The motor in the last pic was harvested from an old massage chair. On 12v it runs pretty slow, might be perfect for this. The one roller will be the drive roller and other will be tension roller.

Got back into the swing of things. Have to look up some 1:1 pictures for loading funnel and some kind of elevation or wheel system.

Re: Great Dane excavating co.
 

Nice to see you back in the groove RW.:cool:
Your conveyor is looking super sweet! Can't wait to see it with rollers installed, a fresh coat of paint and some dirt on the move. :)

As a suggestion for support legs, how's about using a screw drive like Regs dump boxes as a way to power adjust the conveyor height to whatever you want or need?

I'm still along way from building a funnel for mine but my first attempt is going to be like what RVJim has posted. Seems simple enough and effective.
I'd add the link but for some reason my IPad won't copy paste links on here anymore? :confused:

It works!! My wife saw what I had been building and asked what on earth do I need a conveyor for? And I replied " to convey stuff!" Duhhhhh

Re: Great Dane excavating co.
 

That is way cool ! Mike

Re: Great Dane excavating co.
 

Beautiful job RW! That thing runs straight and smooth as silk :cool:
Speed looks great also. What RPM did you go with?
I'm very curious to see what kind of angle you can set it at and still carry material. Such a nice job on the rollers and getting a nice dish to the belt. I bet it will work great!
Set that beauty to about 60 degrees, throw some dirt on it and let's see what happens. :lol:

Re: Great Dane excavating co.
 

Rpm? Uh,, yea, don't know, lol,, the motor was harvested from an old massage chair and sprockets are a couple teeth different. That was running on 7.2v. Originally I planned on 12v but without adding a trimm pot I just hot wired that 2s pack. I haven't got into much of the electrical part yet. I'm still planning on running 12v with a pot for speed control. I'll get the rpm of what the video was running tonight and post so we both will know :). 60 degrees ehh? I'm not going to make this power elevation but will try and make it adjustable to max allowable incline. If I can get material to stay at 45 I will be happy. Might even make it on skids with detachable wheels so I could use a machine to move location of spoil piles. To be honest I never thought about much more than getting the belt moving straight:). Now some more planning !!!and some sort of funnel too. Would be cool to have this in a pit so the dozer could push material into.

Re: Great Dane excavating co.
 

Good Job bro, im digging it!

Re: Great Dane excavating co.
 

Looks good can't wait to see it moving dirt;)

Re: Great Dane excavating co.
 

Your drive roller should be pulling the belt. Looks good, runs quiet & smooth.

I think you'll be hard pressed to get much more than 20° without too much rollback.

Re: Great Dane excavating co.
 

nice conveyor, have you thought about gluing some teeth to the belt to allow you to have a higher incline if need be.
I found on mine (4 feet long)about 15 degrees was the max before the rocks started to roll down hill, also if I slowed it down you can go a little steeper.

Re: Great Dane excavating co.
 

Oops, that redneck engunieerin' again :lol:

Re: Great Dane excavating co.
 

Ouch! I'm not liking the numbers you guys are saying but I never doubt people who speak from experience. At those angles I'm going to need a lot more space to make this all work. :eek:
I was wondering if drive roller must be on the top end? The way it is now all the belt tension is on the bottom which allows the top to have slack and maintain that curve or cupping effect? I guess with heavy material trying to push up a loose belt won't work though..... Ok. Never mind :)
I like Lou's idea using the leading edge of a wiper blade as paddles or teeth on a belt. Just not sure how well they will adhere to the treadmill belt?

Re: Great Dane excavating co.
 

I'm maxing incline out at 70~ or 20 degrees whichever 90 is. Scale wise the pile should have a max height of 25' and a base of around 60-70'. For what I have planned it wouldn't be a max elevation. More for transferring material. What I really need is about six of these lined up for moving material. If this one works out I may built two more for quick transfer of material. I'm planning on spreading cracker dust/ screenings under my deck. And deck is 14x 40'. Lots of work for the perfect sized "toys" :lol: under the deck with height of about two feet.

Re: Great Dane excavating co.
 

good plan.im going to be using mine to feed the screening plant , don't have to build a ramp or pile for the excavator to sit on, just feed the conveyor and job done.

cheers andy

Got the wheels on, it can be elevated a bit more. And lowered completely to the ground. I think it may be a bit heavy for a pintel hitch for the dumptruck but I figure that out later. I still have to get some cross braces and under rollers,, ect,, but you get the idea :)

Re: Great Dane excavating co.
 

The 4 inch width conveyer I had in the basement 5yrs ago was at an approx. angle of 17° & I was getting some roll back of larger dirt lumps & rocks. That was the entire reason for originally building the dirt lump crusher -> the finer the dirt, the less that rolled back. The dirt I was elevating was bone dry too!!! it's almost like beach sand.

Moist dirt and crushed rock, I'm sure you could get greater than 20°.

Your belt RW doesn't seem to have much stretch & bottom drive will probably work fine for you, but you will have to run the tension tighter than if it were top drive. While you're still in the building phase, I'd recommend that you fashion some kind of brush wiper just ahead of the bottom drive roller to keep out foreign material that would affect your roller's traction or jam it up.

I have this problem of fine dirt/dust somehow getting on the inside of the belt of the conveyer that's on my dirt lump crusher, it's a bottom drive with a 5" diameter roller with a 4" width hay baler belt. Even with the conveyer tilted a wee bit, any minute amount of moist dirt that goes through the crusher, moist dirt fines will build up/jam up on one side my conveyer drive roller & stall out the crusher completely. One of these days I'll get ambitious, tear my roadway apart & take that crusher & conveyer to the shop to make some very needed improvements! There's over 200lbs of machine there caked in fine dust to monkey with. :(

Re: Great Dane excavating co.
 

I haven't got to the hopper area yet joe, but it was planning on having some type of loose rubber or brush to guard against rollback into motor/drive roller area. Just not sure yet, I may just cut some rubber fringe as I've got rubber tubes around but no brush type stuff. Well let me go check the wife's bathroom, I may find some brush material :).

Finally got some mail , parts to get the hoe up and running. I was home when the mail man stopped. As he handed me the box the valve assembly fell out!! I know him and told him I may be getting in touch as I was not sure if anything already got loose!!

But thankfully everything was in the box that I ordered!!! Had a large shift of emotions in a short amount of time today:)

Re: Great Dane excavating co.
 

Great timing! You're just about finished project conveyer & now parts arrived for project excavator. :)

The box for my hammer was tore up like that too :rolleyes:, the way the hammer was wrap in bubble wrap it couldn't fall out, but dayum! not much care shown to it during its journey.

Re: Great Dane excavating co.
 

Just wanted to add to the mods, sorry about the Canadian women rant, lost my bearings for a moment, we are sorry.
http://i1357.photobucket.com/albums/...ps7t3hujkb.jpg

And back to the important stuff, going to start work on the hydraulics of the hoe, in Great Dane style, never finishing one project before starting another!!
http://i1357.photobucket.com/albums/...pstzdtvslx.jpg
I have had zero problems with pump and valves in the dozer (except a possible servo death) so that money for my wife's Xmas present showed up in the form of premacon pump and valves. They are going to be the exes new heart and lungs!!

Re: Great Dane excavating co.
 

What? No fourth valve for a thumb?

Re: Great Dane excavating co.
 

I knew someone would say that!!!

Re: Great Dane excavating co.
 

http://i1357.photobucket.com/albums/...psk2fh308b.jpg

But it has had a thought or two :)

Re: Great Dane excavating co.
 

It would definitely work but I would be worried about doing damage to it if you curled the bucket inward too much.
On a 1:1 excavator the thumb relief is always set lower than the bucket relief valve. No relief on a linear actuator.
I mean, the hyd power of the hoe is probably way stronger than what the firgelli can handle and you'd have to be careful with it?

Re: Great Dane excavating co.
 

or he could make a rigid thumb

Re: Great Dane excavating co.
 

Yea I figured that actuator wouldn't be the best option. I more so was trying to one up reg :). But I do have this actuator laying around??? At some point I would like to install a rotary cutter like the small dremmel saw blade on the stick. Kind of like a harvester. I would be able to get under the deck and cut all the little saplings and runners that are growing up into deck. Another project :). So far I've spent about two hours placing and replacing pump, valves, electronics into different positions trying to find the best and most convient fit. Still placing and replacing!! Brain and eyes were starting to bleed!! But I did realize a lot or real estate is in the vertical area :).

Re: Great Dane excavating co.
 

The Firgelli linear actuator in that IzzyBuilt dozer, it doesn't take much force to move the blade up & down, free wheeling the actuator. I didn't notice before installation what ratio it was. I see your actuator there is the 150:1, that might be too high & not free wheel. I doubt you'd injure the actuator anyway.

Say, did you send your email to Firgelli for round bodied actuators? Maybe we'll see those in the near future & something like that would look perfect on your model.

Do you have any trouble those push lock fittings? I have one on the 4206 that I can't get to quit dripping and now I see on this hoe I'm building that one out three of them tank fittings is dripping too. Just push the hose in & pull back to lock it tight, right?

Re: Great Dane excavating co.
 

I have those fittings on all of my hydraulics except the pump connections on my Volvo because I am using standard size hose and fittings(pump is oddball G1/8). I find that the small fittings are fine but the larger 1/4" lines start to weep over time. I bought some of the larger fittings from Princess Auto and they are the worst for it(read Chinese quality). What happens is every time the pressure comes up the hose pushes against the barbs that hold it in place. Eventually it wears the hose and starts to leak. I have never had one come apart though so in that regard I am happy. You just might have to change hoses ever once and a while.

Re: Great Dane excavating co.
 

I think the leftover actuators I had laying around are a bit too big, I think some shorter stroke would be better and yes joe I would go with a little less power, would rather have it stall or force retract than anything. The thumb and harvester attachment will most likely end up being rain day work when digging in summer is getting routine. :).

Joe, the push-lock fittings are great in most applications. Some things to consider. Correct size, angle of hose force, and in my opinion these fittings should have a hard insert to go inside the tube about 1/8" to keep consistent pressure on seal. But the small size doesn't really allow that. Most of the fittings I have been using are only rated for 80~100psi but I've been using them in 300psi range. And the way they work is a tooth washer is on a lock angle to prevent tube from backing out. An o ring is all that makes the pressure seal. To remove the tube all you are doing is releasing the lock washer/spring (whatever ya want to call it). If you got a leaker might just as well replace fitting, the seal may be damaged. BUT, a big issue is to make sure the hose is cut square and sharp edges are bad. 99% of the time just using wire cutters and stuffing it in the hole works:). I cut with razor blade and sometimes run through a lighter flame. (Don't want to heat to the point of balling the ends). Or better yet maybe a heat gun:). As far a locking , yup just push in don't worry about having to pull to lock, it will lock. A good idea is to hold hose next to fitting and eye about where hose should bottom out. Then you have a better idea if hose has been fully inserted. On the 1:1 size fittings I use on small home waterline repair jobs I will so,entires run into a fitting/tube that is a real bugger to seat. And had a situation where a whole 100' roll of waterline had a defect in outside (it had a very small lateral groove or scratch) and couldn't use those type of fittings. They would leak. So another thing to consider if a small scratch or nick, cut on outside of tube it may leak. Uggg enough hoseing around I'm heading to the garage!!! My coffee got cold!!

Re: Great Dane excavating co.
 

It's one of the return lines from the valve back to tank, about 6mm OD. The other 6mm return line seems to be fine. I made sure to cut all lines squarely with a razor blade. Those yellow 6mm hoses are quite soft rubber & maybe I have some brass tube that will fit correctly in the ID, thanx for the suggestion, makes sense.

I used a heat on the suction line, quite a stiff clear rubber/plastic line about 8mm OD, to put a bit of a S curve in it so neither end of the hose was binding on either push lock fitting. I don't see it leaking. I think that's what my problem may be with the 4206 suction line, I need to heat/form the clear hose more so the clear hose is not pulling at an angle on the fittings. :thinking:

The 4mm push lock fittings have 20 bar pressure on them & I have never had a leaker. But then the 4/2.5mm hose is very rigid walled.

Looking at various builds on german forums of this Fumotec 490 I noticed a lot guys didn't use the push lock fittings at all.

Re: Great Dane excavating co.
 

:rolleyes:my thinking too :rolleyes: where's the dopeslap smilie ?

Re: Great Dane excavating co.
 

Ok after a couple of your comments I decided to add a thumb, however I don't know how well it's attached or if it will interfere with the other controls. :)

Yes we both have been accused of being nuts!!!!

I've looked all over the net for an instructional manual for my build, can't find one :). So,,,,, I don't know how the planning will work till well ya all know how it goes, everything in place and then the brilliant idea hits!! Well I've got room for 2 5000mah batteries. Got 10 amps in this puppy. Well more for weight :)
http://i1357.photobucket.com/albums/...psrnvpdeha.jpg

And my modular pump/valve assembly. It was more so I have room for the suction line under pump.

Re: Great Dane excavating co.
 

Tiz only a flesh wound!! And now that I got you attention reg, that dump body payback is rearing it's ugly head!! For those that don't know my purchase from reg was used as blackmail from my wife!! I even have to be the driver to upstate New York on Tuesday. My dumptruck has been leveraged against me for my wife to purchase another four footed, hairy, cat litter eating , snorting, farting, French bulldog. At least it isn't as big as the other residents she makes me share the house with. Sooo, reg, she wants to thank you and I want to,,, well I ain't mailing the truck back!!! Lol!!! So this new little bugger is going to be put in the pit from a young age and to be worked to the bone!! I will hound him till he rolls over!!! I have found an effective way to get the dogs to work, just bury a bone and they will dig!!! I'm really thinking of running cable and a small couch to the garage:).

Re: Great Dane excavating co.
 

Well Cooper in October my daughter , soninlaw and grandson moved back in after they had to sell there house . Another story. Sandy and I and our 2 cats ( who don't care for trucks and trains ) were quite happy , then Saturday Tina our daughter brings there spaniel who has a vacant stare because there is nothing behind the stare ,home who was boarding elsewhere . Anyway the cats reprogrammed him real quick . Take care Mike
