Transmission shaft and its parameters for feed choppers in agriculture

Abstract

The article presents the results of research on the selection of a transmission shaft of an optimal design for a small-sized, simple-constructed crushing device and theoretical determination of its parameters. According to the analysis of rectangular, trapezoidal, oval, tubular and conical transmission rods, trapezoidal rods have an optimal construction. Such rods ensure the convenient transmission of the stalks to be crushed, as well as compression of the material from both sides, accumulation and transmission. For this reason, we adopt a trapezoidal transmission line to the blue stem feed shredder. Based on the results of the theoretical research of transmission rods, it was determined that the stalks transmitted from the rod to the crusher depend on the shape of the rod and some parameters. According to theoretical studies, in order to transfer the crushed feed to the device and its supply channels with a comfortable and low resistance, the length of its transfer chute should be 65 cm, the width of the front part of the chute should be 40 cm, the width of the part connected to the supply chute should be 20 cm, and the slope of the chute should be 27°.
