It features a simple structure, convenient disassembly and maintenance, and a long service life. This solves the problem of cumbersome replacement of worn plow wheel bearings.

[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions:

[0005] A plow wheel structure with detachable and maintainable bearings includes a positioning ring, a bearing that is inserted and fitted into the positioning ring, an end cap that is pressed and limited by the bearing on the side of the positioning ring, a plurality of gripping rods that are evenly spaced and distributed in a ring on the positioning ring, the gripping rods extending outwards and having plowing claws at their front ends, a plurality of bolts that are evenly spaced and distributed in a ring and penetrate the gripping rods and the positioning ring on the end cap, and a plurality of nuts that are threaded and fixed to the bolts on the outer end face of the positioning ring.

[0006] Preferably, both ends of the gripping rod are provided with reinforcing pressure rings, and the reinforcing pressure rings are fixedly connected to the gripping rod by rivets.

[0007] Preferably, the reinforcing pressure ring is located at the middle of the gripper bar.

[0008] Preferably, the outer end face of the plow claw is a pointed structure, and the gripper bar and the plow claw are an integrated structure.

[0009] Preferably, the plow claw has an arc-shaped structure.

[0010] This invention can achieve the following effects:

[0011] This invention provides a plow wheel structure with detachable and maintainable bearings. Compared with existing technologies, it features a simple structure, convenient disassembly and maintenance, and a long service life. It solves the problem of cumbersome replacement of worn plow wheel bearings. Attached Figure Description

[0016] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0017] Example: Figure 1 , Figure 2 and Figure 3 As shown, a plow wheel structure with detachable and maintainable bearings includes a positioning ring 4, a bearing 7 that is inserted and sleeved within the positioning ring 4, and an end cap 9 on the side of the positioning ring 4 that limits and presses against the bearing 7. The positioning ring 4 has 16 equally spaced ring-shaped gripping rods 1 extending outwards, with plowing claws 2 at their front ends. The plowing claws 2 have an arc-shaped structure, with pointed outer ends. The gripping rods 1 and plowing claws 2 are integrated. Reinforcing rings 3 are provided at both ends of the gripping rods 1, and are fixedly connected to the gripping rods 1 by rivets 5. The reinforcing rings 3 are located in the middle of the gripping rods 1. The end cap 9 has four equally spaced ring-shaped bolts 6 that penetrate the gripping rods 1 and the positioning ring 4. The outer end face of the positioning ring 4 has four nuts 8 that are threadedly sleeved and fixed to the bolts 6.

[0018] In summary, this plow wheel structure with detachable and maintainable bearings features simple structure, convenient disassembly and maintenance, and long service life. It solves the problem of cumbersome replacement of worn plow wheel bearings.
