AI Technical Summary
Existing agricultural rubber wheels suffer from the silt sealing effect and stress concentration in the supporting structure when used in muddy fields, resulting in high slippage rate, unstable grip performance, and easy structural damage, which cannot meet the needs of efficient agricultural operations.
It adopts a composite structure design of convex and plate-shaped barbs, combined with curved spokes and an inverted triangular perforation system, to form a dynamic mud discharge channel, optimize stress distribution and grip performance.
It significantly reduces mud slippage rate, improves grip efficiency and structural durability, and enables lightweight and efficient mud operations.

A non-slip rubber wheel used in mud and having two kinds of spikes, characterized in that, include: Rubber anti-slip parts and metal support parts; The rubber anti-slip part includes a wheel surface, raised serrations, and plate-shaped serrations; The metal support includes a rim, a hub, a perforation, and spokes; The wheel surface is wrapped around the outer circumferential surface and both axial sides of the wheel rim; The convex barbs have a trapezoidal structure, with the lower end fixed to the wheel surface, the upper end being a flat surface, and the surrounding area being an inclined slope. The plate-shaped perforations are flat plate structures that are fixed to the wheel surface at a preset tilt angle; The convex barbs are arranged along the circumference of the wheel surface, and in the direction of wheel surface width perpendicular to the circumference, adjacent convex barbs are arranged on both sides of the center line of the wheel surface, forming an alternating arrangement; Along the circumferential direction of the wheel surface, a plate-shaped barb is provided between every two adjacent convex barbs; The wheel spokes are provided in three parts, arranged in a circular array, with one end connected to the rim and the other end connected to the hub; The spokes include a near-rim section directly connected to the rim and a near-hub section directly connected to the hub. The near-hub section is bent towards the hub relative to the near-rim section, so that the spokes as a whole present a curved shape. The curvature of the curve matches the outer circumference of the hub. The perforations are located in the area between two adjacent spokes and are arranged in an inverted triangle from the inside to the outside along the radial direction of the rubber wheel.
