Study of the kinematics of a disc-pin working body

Abstract

Currently, there are a large number of tillage disc working tools. The article provides a detailed analysis of their designs. The main disadvantage of all structures is slippage during its interaction with the soil, which greatly reduces the quality of tillage. To eliminate this drawback, a new design of a soil-cultivating disc-pin working body was developed. The purpose of this study was to study the kinematics of a soil-cultivating disc-pin working body to ensure uniform operation without slipping. The rotation of the disk is ensured by a pin drum. During the forward movement of the trolley, the pins enter the soil, engage with it and turn the pin drum until, due to this rotation, they come out of the soil. A mathematical model of the movement of the ends of the pins in the plane of motion and taking into account the angle of attack has been compiled. Based on kinematics studies, the main parameters of the disc-pin working body are substantiated, the performance of which has been confirmed experimentally.
