digging potatoes (modified)

[Archimede Pitagorico]

Good morning to all... in time "lost" I wanted to evaluate the idea of changing a digging/ picking potatoes used to "better" it according to my needs. at iron level welds and mechanics I arrange discreetly. . at the level of oleodynamics are almost zero. I'll explain.

the draft you see is to be interpreted as:
- black, chain tractor= existing
- red, convoy ramp = homemade
- blue, 2nd conveyor chain = recoverable
- orange and purple, case and product case support = not relevantwith a tractor from 25-30 cv to cardan I wanted to eliminate the bike with the chain, mount a hydraulic pump (if with multiplier or not you will tell) and mount a hydraulic motor (suitable) on the first chain + a second hydraulic motor in the second chain. 1 flow regulator in the second motor to adjust the chain speed (very slower... manual screening with operator). a 3-position distributor (pos. 0-1 fixed. Pos. 2 spring return) to be able to reverse the direction of the main tape only in case of jamming with a simple gas station (with return to zero spring).

that pump, multiplier, reservoir, engines, distributor, flow regulators can serve I ask who knows more about me.. but all this according to you is feasible? and at what prices?. leaving the possibility of wandering between workshops and recoveries of course

ps for the most curious, I would remove the 3rd point on the tractor and turn it into "semi-ported tool" given the structure "corposa" for a 30cv.

Hello and thank you.ps if the subject did not appear properly the moderators can move it to the appropriate section.

I apologize for my non-relevant answer, but I did not understand the advantage of transforming the mechanism from purely mechanical to hydraulic, I try to explain myself better; historically the father of all modern hydraulic machines is the cyngolate excavator in which there was an endothermic engine, two large pumps plus a small for the services attached to a coupler and the oleodynamic system that ruled everything: right and left cingle advancement, cingoli rotation, arm lifting, forearm call, excavation with the bucket etc. etc.
things that had previously been done with brainchilds of pulley ropes and instead now it works all very well thanks to simple hammers and hoses.

but in your case it seems to me that the use is only two, from what little I understand, you are sure that it is convenient to put reservoir, pumps, distributors, hydraulic motors etc etc. to transform mechanical energy into oleodynamic energy, moreover I believe that physically every transformation of energy causes dissipation of a part of it.

I have three machines for potato harvesting and therefore something I also understand of practical use in addition to mechanics, and for this reason I recommend you to let go of the second tape slightly faster than the first, as well as not to make it semi-ported. .
What tractor would you use to operate the whole thing?

first of all thanks for the answers, we talk about family gathering (3 families) and agricultural hobbies in equal measure

the modification would be given the soil "not suitable" to potatoes so not sandy or vaglia as you have to... some pebble of too much creates jams (sometimes you make meters and nothing happens, other times they get stuck in the catenary and to unlock them I have to put the sync in pdf and back to get the chain back, get down and extract them)... a nuance. the oleodynamics would have the possibility of (with the distributor) reverse the rotation of the catenary without stopping the pdf, adjust the speed of the second tape as it says bip (even if I would have made it slower not faster the second) with a flow regulator. the choice of the semi-ported is given (in instinct) by the weight to be charged on the lift of an isodiametric 25-30 cv type (ferrari,pasquali,bertolini) that weigh on average 8-10 qt and carry max to the 4-5 qt rotules but leaving from the rotules of the tools drops drastically the flow obviously. I imagine it is difficult to reverse with a tool of almost 2 meters long (+ 2.54 meters of tractor) at the end of the field if the tool is semi-ported, but I don't know if the lift of my isodiametric manages to raise the tool with the second chain, harvested product and man "seater" without impennating for this I would try to put the axis of the collected more in the green center possible

 

[bip]

it does not raise it but above all you will have big problems pulling it once it is buried

I hoped I had enough cavalry to land with an isodiametric 4x4... for what I wanted to do:frown:
but according to you, do you have any idea that pump (port and pressure) and rotating engines would serve to achieve this?

 

[bip]

It is not a matter of power, it is a problem of weight, the tractor is too light. .

Okay, thanks, parking the idea:frown:
