Design of Mechanism for Moving Soil -- Need help with an instability

[Micheal_Leo]

This mechanism move the soil through steel plates attached to chain and gears.The mechanism is unstable since there will be high Fx and Fy of hydrualic cylinder,Any other way to stable mechanism ? or any other design ideas please
Thank you

 

[Baluncore]

What does this machine do?
Is it pulled through the soil by a tractor?
Which way does it travel?
A plough or a ripper tine will be lower at the front, so it pulls down, into the soil.
Is the front on the left in the diagram?

 

[Micheal_Leo]

Thank you for reply.This mechanism extract soil when tractor moves during harvesting and also soil transport .The sharp edge at front is used to remove soil and the steel plates will used for move the soil on base plaform

 

[hutchphd]

There are bucket chain excavators used in mining. Also bucket wheel excavators which use rubber transport belts. These are old designs that have been well tested ..... (?)

What is being harvested?
Is this a side view or a plan view?
Stability comes from the way it is attached to the tractor. Where are the attachment points?

yes it is same with my mechanism

crops harvested but also remove soil at the same time
This is Front view
This mechanism attached with another machine not tractor and the attached point is this

 

[jbriggs444]

This is Front view

Are you sure? It looks to me like a side view with the front pointed to the right.

The wheel on the lower right appears to be attached to the frame while the scoop below appears to be attached to the hydraulic cylinder and hinged on the left. This means that the clearance between belt and scoop is variable, right?

 

[hutchphd]

yes it is same with my mechanism

What part is the same? What is your "instability" exactly?

 

[Baluncore]

I don't yet have a clue as to what that machine does, which way is up, how it works, or how big it might be.

Maybe it is just my remote mind reading ability that is failing me.
I don't feel too bad though since, if the OP actually wanted assistance, they would have provided those necessary details.

 

[jbriggs444]

My best guess is that we are talking about an elevating tractor-scraper.

Edit: linked to the design section of the Wiki article on the subject.

I don't yet have a clue as to what that machine does,

One can fall in love with graphics and forget about the practicalities if a pretty design . I'm assuming that the wheels rotate clockwise and the soil is lifted by that wedge. The design could work for sand and fine gravel but what happens when a single stone gets trapped in the channel below?

The OP seems to expect us to get the whole picture on minimal description.

My best guess is that we are talking about an elevating tractor-scraper.

But on a smaller scale, $12 on e-Bay:

[Baluncore]

The towed scraper generates a surface from the weighted average of the tractor's rear wheels and the scraper's wheels. That is an interpolation, it will lower the spatial frequency, and always attenuates the undulations in the surface. The wide wheelbase of the scraper better follows the regional cross-slope, again interpolating and attenuating.

A front pusher blade, like on a bulldozer, or a front-end-loader bucket, performs an extrapolation of level, forwards from the vehicle wheelbase. That will always increase the spatial frequency of, and amplify, the ground undulations.

Yes, but that's just for the brochure (not the scraper itself).

Oh jeeze! I wondered why it was so cheap!

 

[Micheal_Leo]

since there is only one cylinder on other side no cylinder so tilt will happen on one side

the function of this mechanism is to covered the hole where seed transplanting take place.Means there wil be hole created and seed will goes on than the mechanism that i have design will adjust soil for covering of holes


THis mechanism build for agriculture mechanization engineering

Thank you very much sure will read it

"Seed transplanting"?

Is the point to extract seedlings from a field, place seeds in the resulting holes and cover them up?

Is the point to dig holes, place seedlings into the holes and cover them up?

Seeds are normally handled with "planters" or "drills" in a one pass operation on a prepared field.

How does the machine you have drawn help accomplish any of this? How is it drawn through the soil? Which way does it move? Is soil being extracted? Deposited? Is the conveyor powered? Which way does it move? Where does the dirt come in? Where does the dirt go out? What sort of seeds or seedlings are to be handled? Does this machine handle them or does it just move soil afterward? What machines currently exist to perform these tasks?

Why are you being coy and refusing to provide any useful information?

please see this how it works

 

[Baluncore]

It is because we are being trolled.

What is being harvested?

crops harvested but also remove soil at the same time

Which all contradicts:

Little bit misinformation happen between me and colleagues so less information delivered
