Theory of share digging unit in sugar beet harvesting machines

Abstract: The motion of a soil layer together with a sugar beet root fixed in it along the surfaces of a pair of flat, oblique shares is analysed. During the last phase of this motion a beet root gets in direct contact with planes of shares. The influence of share position angles onto the machine maximum allowable forward velocity was defined at which, in particular soil conditions, the end part of the root would not be broken and left in the soil. Assuming the value of the vertical force binding the beet root with the soil as 0.2 kN and unitary resistance of soil already loosened by shares as 2.0 kNm-2 and taking the apex angle of the beet root come as 20–28º, the highest value of the machine velocity limit may be achieved when the angle 2γ of the divergence of shares will be kept between 26 and 32º and the angle β of deflection of share plane from vertical will be 30º.
