[0002] A self-propelled power machine used to pull and drive operating machinery to complete various mobile operations is one of the most common tools in agricultural production. It is used to change the torque, speed and direction of movement transmitted from the driving shaft to the driven shaft according to different working conditions. The gear-driven gearbox is generally composed of a case and several gear pairs, and is an important component of the tractor.

[0003] Due to the long-term use of the tractor, the connection structure on the tractor will be offset or damaged due to the erosion of rain and the shaking encountered during driving. For example, when the tractor is damaged and repaired, the rear axle is removed and then installed. The original connection structure will not correspond to it, and personnel are required to straighten or repair the connection part before installation and fixation. This is more troublesome, and improper operation may easily cause the connection parts to break.

[0004] Therefore, it is necessary to propose a tractor gearbox rear axle with adjustable clearance to solve the above problems. Utility Model Content

[0007] Preferably, filling blocks are disposed on both sides of the sliding block, the filling blocks are elastic, and the filling blocks are placed inside the corresponding sliding grooves.

[0008] Preferably, both ends of the interior of the drive axle housing are drivingly connected to half shafts, the two half shafts extend out of the drive axle housing, and the outer sides of the extended ends are connected to wheel hubs.

[0009] Preferably, a wear-proof component is telescopically arranged in the middle of the bottom end of the drive axle housing, and the wear-proof component includes an wear-proof block. An embedded groove is opened at the bottom end of the drive axle housing, and a plurality of buffer components are fixed in the embedded groove. The top end of the wear-proof block is fixed to the bottom of the plurality of buffer components.

[0011] Preferably, a non-slip pad is fixed to the bottom end of each of the two sliding blocks.

[0012] Technical effects and advantages of the utility model:

[0013] 1. When a bump appears on the road surface, the bump will come into contact with the anti-wear block and lift up the anti-wear block. At this time, multiple buffers will act as buffers to prevent the collision force generated by the bump and the anti-wear block from directly acting on the drive axle housing. The friction generated by the bump on the road surface will first act on the anti-wear block, replacing the drive axle housing to provide protection.

[0014] 2. In the actual operation of the utility model, the two sliding blocks can slide in the corresponding sliding grooves respectively, so as to adjust the positions of the two sliding blocks, so that the connecting ears at the top of the sliding blocks can be connected to the bottom of the tractor. At the same time, when the position of the sliding blocks is determined, the sliding blocks and the corresponding fixing holes can be fixed by fixing bolts, so that the rear axle can change the position of the connecting ears through the sliding blocks and be installed correspondingly to the bottom of the tractor.

[0015] 3. After the sliding block is fixed, it will fit tightly with the rear axle. The internal vibration sensor can detect the vibration of the rear axle in real time. When the rear axle is damaged or broken, the vibration will increase. The vibration sensor can detect the damage and remind the personnel to repair it in time. At the same time, the filling block can resist the two sides of the sliding block to enhance the fixing effect. At the same time, it can reduce the gap inside the sliding groove to prevent rainwater and dust from entering the sliding groove and causing accumulation. BRIEF DESCRIPTION OF THE DRAWINGS
