Study on the parameters of bars of the potato digger ploughshare

Abstract

Currently, potato diggers used in agricultural production in Uzbekistan have a number serious drawbacks. In particular, they have a high material and energy capacity, and their use in small farms and personal subsidiary farms is considered less effective. The purpose study is to substantiate the parameters vibrating rods potato digger ploughshare. The authors proposed a potato digger with lattice ploughshares equipped with vibrating rods. Swinging rods are attached to the main ploughshares, the oscillation which is carried out from the tractor power take-off shaft. A diagram a ploughshare with vibrating rods and a mechanism for transmitting motion is given. The laws theoretical mechanics are used in the research. In the experiments, losses and damage to potatoes, as well as traction resistance, were taken as a criterion for evaluating the performance potato digger. As a result theoretical studies carried out, analytical dependencies and mathematical models were obtained that allow determining the parameters rods. It is proved that the length bars the potato digger ploughshare should be 25 cm, the number bars is 14 pieces, the distance between the bars is 3 cm, the diameter the bars is 1 cm.
