Auger orienting device for planting sugar beet root crops

Abstract

The mechanization of the technological process in planting sugar beet root crops determines the efficiency of sugar beet seeds production. At the same time, the limiting factor is the use of manual labor in the process of planting sugar beet mother liquors. The article presents a three-dimensional model of an auger orienting device with given design parameters for sowing sugar beet mother liquors. The power for the drive of the auger rollers orienting device is determined, which provides the necessary piece-by-piece supply of sugar beet mother liquors at a speed of the sowing unit of 3.6 km/h. The authors carried out the consistency substantiation of the kinematic parameters in auger orienting device operation with the landing apparatus of the sowing machine, taking into account the design parameters of the presented device. The energy calculation of the auger drive orienting device was carried out and the loads acting on the drive shaft of the roller were determined. The gear wheels of the roller drive have been designed, and the stress-strain analysis of the drive shaft of the auger roller has been carried out. The main parameters of the simulated spur gear were determined using the KOMPAS 3D computer-aided design system, which ensure the reliable operation of the auger orienting device of the machine for planting sugar beet root crops with the required productivity.

Rotary paddle orienting device for planting root crops

“…Orientation of the root crop with the tail part down occurs due to the conical shape of the tail part of the root crop and the moment of gravity arising in the V-shaped groove formed by the combined blades of the rotors, then the root crop is fed through the guide tray 8 into the planting cones of the planting apparatus. According to agritechnical requirements, the speed of planting machines aggregation when planting sugar beet mother plants varies from 1.8 to 3.6 km/h (0.5 ... 1.0 m/s), and the landing step is 0.6 or 0.7 m [8][9].…”

“…The frequency of rotation of the lander, providing a landing step of 0.6 m, at the maximum speed of the lander, is determined by the expression [8][9]:…”
