Steering arm for front axle of medicine spraying machine

Abstract

The invention discloses a steering arm for a front axle of a medicine spraying machine, which is arranged at each of two ends of the front axle and comprises a steering part, an edge reduction device and a transfer part, wherein the steering part comprises a steering shaft and a vertical shaft sleeve, the vertical shaft sleeve is sleeved on the outer ring of the steering shaft, the top end of the vertical shaft sleeve is fixedly connected with the outer wall of the transfer part, the bottom end of the vertical shaft sleeve is fixedly connected with the edge reduction device, the transfer part is connected with the end part of the front axle, and the steering part is connected with the end part of the front axle through the transfer part. The steering arm for the front axle of the medicine spraying machine, disclosed by the invention, effectively isolates muddy water and dust, effectively prevents the steering shaft and the reduction device from being polluted by external pollutants, ensures the normal steering function of the steering arm, and prolongs the service life of an oil seal and a gear. The steering arm disclosed by the invention has the characteristics of good practicability, good stability, good sealing property, high reliability, long service life, and the like.

Description

technical field [0001] The invention relates to the technical field of spraying machines, in particular to a front axle steering arm of a spraying machine. Background technique [0002] The front axle of the sprayer is mainly used for steering, and the two ends of the front axle are equipped with steering arms for steering. When the sprayer needs to turn, the steering drive device can drive the steering arms at both ends of the front axle to swing at a certain angle, so as to realize spraying. The steering function of the medicine machine can change the spraying route of the medicine sprayer. [0003] The bottom of the steering arm in the prior art is equipped with a side reducing device, which includes a gear reduction mechanism. The driving gear is installed on the bottom of the steering arm near the ground, and the middle part of the driving gear is equipped with a rotating shaft. During the process of spraying pesticides on crops, muddy water and dust can easily enter t...

Problems solved by technology

[0003] The bottom of the steering arm in the prior art is equipped with a side reducing device, which includes a gear reduction mechanism. The driving gear is installed on the bottom of the steering arm near the ground, and the middle part of the driving gear is equipped with a rotating shaft. During the process of spraying pesticides on crops, muddy water and dust can easily enter the joints of the driving gear or the rotating shaft near the ground, which will cause damage to the oil seal of the rotating shaft and the driving gear, resulting in failure of the steering system and reducing the service life of the steering arm
