Axle for plant protection machine

Abstract

The invention discloses a plant protection machine axle which comprises an axle housing, fixing sleeves are mounted on the left side and the right side of the axle housing, sliding sleeves are slidably mounted in the fixing sleeves, a taper hole is formed in the end, away from the axle housing, of each fixing sleeve, the taper holes expand outwards, the sliding sleeves penetrate through the taper holes and extend outwards, taper tiles are inserted into the taper holes, and the outer side faces of the taper tiles abut against the fixing sleeves. A clamping sleeve is arranged at the end, away from the axle housing, of the fixed sleeve, a taper hole is formed in the clamping sleeve, an opening in the end, close to a wheel, of the taper hole is large, an opening in the end, away from the wheel, of the taper hole is small, and a limiting edge extending in the length direction of the sliding sleeve is arranged on the outer wall of the sliding sleeve and is a transversely-extending plane. Limiting grooves are formed in the fixing sleeves and open towards the wheels, top plates are clamped in the limiting grooves, inserting plates are arranged on the top plates, and the inserting plates are inserted in the taper holes. According to the novel axle, the connecting strength of the fixed sleeve and the sliding sleeve can be guaranteed, and the fixed sleeve and the sliding sleeve are prevented from being collided and abraded when a vehicle runs.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an axle for a plant protection machine. Background technique [0002] Agricultural vehicles often need to drive in the fields. Due to the influence of the width of the farmland and the ridges, the trafficability and driving safety of the vehicles gradually show problems. Driving in the farmland, forcibly entering the farmland to work will inevitably damage the crops. [0003] Based on this, the application number 201510137975.3, titled the invention patent of wheel base and height adjustable locomotive drive axle, proposes that an axially fixed guide sleeve is installed on the side of the drive axle housing, and an axially fixed guide sleeve is sleeved on the axially fixed guide sleeve. Sliding guide sleeve, the axial sliding guide sleeve can slide laterally along the axial fixed guide sleeve, in addition, a half shaft is installed in the axial spline sleeve, the half shaft...

AI Technical Summary

Problems solved by technology

However, during the actual operation of the vehicle, there will inevitably be bumps and jams. Due to the existence of the matching gap between the axial fixed guide bush and the axial sliding guide bush, collisions will occur between the two fittings. After the vehicle has been running for a long time, the collision will Cause wear and deformation between the axial fixed guide sleeve and the axial sliding guide sleeve, resulting in the failure of the sliding fit between the axial fixed guide sleeve and the axial sliding guide sleeve, or the occurrence of axial sliding guide sleeve due to excessive deformation Fracture, affecting the safety of the car body, needs to be improved
