Abstract

The invention discloses an agricultural omnidirectional wheel which comprises traveling wheels, a traveling drive mechanism, a steering mechanism and a jacking mechanism. The traveling wheels are coaxially arranged on a wheel shaft in a transmission manner, the wheel shaft is rotatably assembled in a spindle sleeve, the spindle sleeve is fixedly connected with a frame base through supporting columns, the traveling drive mechanism drives the traveling wheels, the steering mechanism comprises a steering shaft and a steering motor, the steering shaft is assembled on the frame base through a thrust bearing, one end of the steering shaft is in transmission connection with the fixedly mounted steering motor, the other end of the steering shaft is vertically and fixedly connected with the spindle sleeve, the jacking mechanism comprises a jack, a steering support and a steering supporting wheel, one end of the jack is connected with the steering shaft, the other end of the jack is connected with the steering support, the steering support and the middle of the spindle sleeve are slidably assembled along a jacking direction, an the steering supporting wheel is assembled at the bottom of the steering support by the aid of a universal structure. A steering angle of the agricultural omnidirectional wheel is large, needed steering radius is small, the agricultural omnidirectional wheel conveniently drives and moves in farmlands and has good traveling ability in different landforms, and seedling pressing is decreased.

Description

technical field [0001] The invention belongs to the wheel system structure of farmland machinery, and in particular relates to an omnidirectional agricultural wheel capable of steering at any angle under various terrain conditions. Background technique [0002] At present in our country, farmland field operations are mainly manual, and the level of mechanization technology is not high. Some existing agricultural machinery has the problems of low precision and low efficiency when performing plant protection operations, and has a relatively high performance when turning in the farmland. The large turning radius, the disadvantage of inevitably overwhelming many crops when working. In particular, China's main food crops, rice, wheat, corn, etc., grow densely and the row spacing is extremely small. During the growth period, there is no corresponding agricultural machinery that can pollinate, spray pesticides and weed in the field without harming the plants. And other fine operati...
