Three-freedom-degree weeding robot

Abstract

The invention discloses a three-freedom-degree weeding robot. The three-freedom-degree weeding robot is characterized in that the bottom of a frame is provided with support rods, wheels are arranged at the bottoms of the support rods, and each wheel is connected with a wheel motor; a linear moving device is arranged at the bottom of the frame, a linear moving device motor is connected with the linear moving device, and the output end of the linear moving device is connected with a first platform; two ends of each drive arm are respectively provided with a through hole and a hinge hole, the output shaft of each drive arm motor penetrates the corresponding through hole to be hinged to the first platform, the output shaft of each drive arm motor is in interference fit with the corresponding through hole, the through holes of the two drive arms are located on the same horizontal plane, and the two drive arms are collinear and vertical to the output direction of the linear moving device; the hinge hole of each drive arm is connected with one end of one driven arm in a hinged manner, the other ends of two driven arms are hinged to a second platform, the second platform is located below the first platform, the second platform is provided with a weeding rotary cutter motor, and the output shaft of the weeding rotary cutter motor is located below the second platform and connected with aweeding rotary cutter.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and relates to a three-degree-of-freedom movable weeding robot. Background technique [0002] The concentration of land has led to the emergence of farms with arable land. However, farms require more efficient mechanized and automated management. Large-scale mechanized and automated weeding of farms is imminent. [0003] In order to solve the problem of low crops or weeds in the early stage of crop growth in large farms, a group of weeding robots have appeared on the market, which can automatically cut the weeds on the path; but the existing weeding robots, the weeding cutter is fixed The setting or can only move in one direction, cannot move flexibly, cannot be suitable for complex field environment, and the cutting position is single. Contents of the invention [0004] The object of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide a thre...
