Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a wear-resistant and abrasion-resistant support roller for agricultural machinery. Background Technology

[0002] Track rollers are an important component of agricultural machinery. They are mainly used to support and guide the weight and movement of agricultural machinery during field operations, ensuring smooth operation, reducing pressure on the ground, and improving work efficiency and quality. Common agricultural machinery track rollers include steel rollers, rubber rollers, and plastic rollers, and track rollers made of different materials have different performance characteristics.

[0003] Traditional track rollers typically support the axle through bearings on both sides inside. However, the middle of the axle is suspended and lacks support. Under heavy loads, the middle of the axle is prone to bending and deformation, leading to axle damage and reduced service life. Therefore, we propose a wear-resistant track roller for agricultural machinery. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a wear-resistant and abrasion-resistant support roller for agricultural machinery.

[0005] This utility model is achieved using the following technical solution: a wear-resistant and anti-wear support roller for agricultural machinery, comprising a support roller, the surface of which is provided with an anti-corrosion layer, an axle inside which is provided, a cavity inside which is provided, positioning grooves at both ends of the support roller, a support bearing inside the cavity, limit rings at both ends of the support bearing, a fixing rod fixedly connected to the end of the limit ring away from the support bearing, a bearing fixedly connected to the end of the fixing rod away from the limit ring, a sealing gasket inside the positioning groove, and sealing end caps fixedly installed at both ends of the support roller.

[0006] Through the above technical solution, by placing the limiting ring inside the cavity, when one end of the bearing enters the positioning groove, it will compress the sealing gasket to ensure sealing. Then, the sealing end cap is installed and fixed, and the bearing is compressed and fixed by the sealing end cap. The above steps are repeated to install the other bearing and sealing end cap. At this time, the two limiting rings will compress and fix the support bearing, which facilitates the subsequent disassembly and replacement of the support bearing. The support bearing and the two bearings support the axle, avoiding the middle of the axle being suspended, improving the structural strength and load-bearing capacity, and extending the service life. The anti-corrosion coating material is polyurethane, which prevents the outside of the support roller from being corroded by the anti-corrosion layer, thus improving the service life of the support roller.

[0007] As a further improvement to the above solution, the surface of the wheel axle is rotatably connected to the support bearing and the inner wall of the bearing, and the support bearing is located in the middle of the cavity.

[0008] The above technical solution provides support for the middle part of the wheel axle through the support bearing.

[0009] As a further improvement to the above solution, the number of fixing rods is set to several, and the several fixing rods are arranged in a circle with the limiting ring as the circumference.

[0010] The above technical solution improves the stability of the connection to the fixed ring by using several fixing rods.

[0011] As a further improvement to the above solution, one end of the bearing is in contact with the surface of the sealing gasket.

[0012] With the above technical solution, when one end of the bearing enters the positioning groove, it will squeeze the internal sealing gasket, thus achieving a preliminary sealing effect.

[0013] As a further improvement to the above solution, the ends of the sealing end caps that are close to each other are in contact with the surface of the bearing.

[0014] With the above technical solution, the sealing end cap is installed and fixed to the support roller with bolts, which facilitates subsequent disassembly. Moreover, after the sealing end cap is installed and fixed, it will squeeze the bearing, thus playing a secondary sealing role.

[0015] As a further improvement to the above solution, an upper oil pipe is fixedly connected to the inner wall of the support roller, and a sealing cap is threaded to one end of the upper oil pipe.

[0016] The above technical solution ensures that the oil supply pipe remains sealed by the sealed tank, preventing lubricating oil from leaking out. The threaded connection between the sealing cap and the oil supply pipe also improves the ease of disassembly.

[0017] As a further improvement to the above solution, the end of the upper oil pipe away from the sealing cover is connected to the cavity.

[0018] The above technical solution allows lubricating oil to be injected into the cavity through the oil inlet pipe, lubricating the wheel axle and support bearing, reducing friction between them, and thus extending their service life.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention utilizes a supporting bearing, a limiting ring, a fixing rod, a bearing, a sealing gasket, and a sealing end cap. Specifically, the limiting ring is placed inside the cavity. When one end of the bearing enters the positioning groove, it compresses the sealing gasket, ensuring a tight seal. Then, the sealing end cap is installed and fixed, further compressing and securing the bearing. The above steps are repeated to install the other bearing and sealing end cap. At this point, the two limiting rings compress and fix the supporting bearing, facilitating subsequent disassembly and replacement. The supporting bearing and the two bearings provide support for the axle, preventing the axle from being suspended in the middle, improving structural strength and load-bearing capacity, and extending service life.

[0021] This utility model incorporates a sealing gasket, a sealing end cap, and an oil inlet pipe. Specifically, the oil inlet pipe allows lubricating oil to be injected into the cavity to lubricate the axle and support bearing, reducing friction between them and extending their service life. The sealing gasket and sealing end cap ensure a tight seal, preventing lubricating oil leakage from the cavity. Attached Figure Description
