Description

Technical Field

[0001] This utility model relates to the field of wheel hub technology, specifically to an agricultural machinery wheel hub unit. Background Technology

[0002] Agricultural machinery, also known as agricultural equipment, refers to machinery and equipment used in agricultural production and related agricultural activities such as the initial processing of agricultural products. Tractors: Machinery driven by internal combustion engines for traction and transporting materials, including wheeled tractors, tracked tractors, walking tractors, and machine-operated tractors; they are the main machinery in farmland operations. Soil tillage machinery: Machinery used for tilling and preparing soil, including tractor-drawn plows, tractor-drawn harrows, rotary tillers, rollers, combined tillage machines, soil compactors, and other soil tillage machinery; they effectively improve soil structure and promote crop growth. Farmland infrastructure construction machinery: Specialized machinery used for farmland infrastructure construction, including ditching and ridging machines, ditching and pipe-laying machines, loaders, and graders; these machines play a vital role in farmland infrastructure construction.

[0003] Currently, in existing technologies, the surface treatment process for wheel hubs varies depending on the characteristics and needs of different vehicle models, and can be broadly categorized into two types: baking paint and electroplating. However, the environment in farmland is harsh, and during prolonged operation, wheel hubs inevitably collide with stones, causing the anti-rust measures on the wheel hub surface to fail. Therefore, we propose an agricultural machinery wheel hub unit. Utility Model Content

[0028] Please see Figure 1 - Figure 5This utility model proposes an agricultural machinery hub unit, including a device body 1. The device body 1 includes an outer wheel rim 101. A support 102 is fixedly connected to the inner wall of the outer wheel rim 101. Bolt holes 103 are opened on the surface of the support 102. An installation ring 104 is fixedly connected to the inner wall of the outer wheel rim 101. A connecting hole 105 is opened on the surface of the installation ring 104. The number of connecting holes 105 is the same as the number of spokes of the support 102, and the position of the connecting holes 105 is offset from the position of the spokes of the support 102.

[0029] The main body 1 of the device is provided with a protective device 2, which includes: an arc-shaped baffle 201, a mounting hole 202 on the surface of the arc-shaped baffle 201, a connecting block 203 rotatably connected to the surface of the arc-shaped baffle 201, the connecting block 203 cooperating with the connecting hole 105, and the surface of the connecting block 203 sleeved with the inner wall of the connecting hole 105, a positioning block 204 sleeved on the inner wall of the mounting hole 202, the surface of the positioning block 204 being fixedly connected to the end face of the threaded rod 205, and a fastening nut 206 threadedly connected to the surface of the threaded rod 205, the surface of the fastening nut 206 having an outer arc that cooperates with the inner arc surface of the arc-shaped baffle 201. On the surface of the positioning block 204, anti-collision rubber 207 is fixedly connected.

Rotate the fastening nut 206 so that the fastening nut 206 disengages from the threaded rod 205, thereby releasing the fixation of the positioning block 204. Pull out the positioning block 204 and the anti-collision rubber 207 for replacement. Insert the new positioning block 204 into the mounting hole 202. Screw the fastening nut 206 into the surface of the threaded rod 205. Continue to rotate the fastening nut 206 so that the surfaces of the anti-collision rubber 207 and the fastening nut 206 fit against the two sides of the arc-shaped baffle 201, thereby completing the replacement. Insert the connecting block 203 back into the corresponding connecting hole 105 and rotate the connecting block 203 to complete the installation.
