Description

TECHNICAL FIELD

[0002] The mini-tiller is a kind of common agricultural machinery for ploughing, mainly powered by small diesel engine or gasoline engine, with the characteristics of light weight, small size, simple structure, etc., and is widely used in dry land, paddy field, orchard, etc. in plain, mountainous area and hilly area. The riding type mini-tiller belongs to one kind of mini-tiller, and the convenience of use of the operator is improved due to the provision of seat and other equipment, so most common mini-tillers are riding type mini-tillers at present.

[0003] For different geological conditions, the structure and material of the walking wheel used on the riding type mini-tiller also differ. When working in dry land, the riding type mini-tiller uses a special dry land wheel as the walking wheel. The dry land wheel ensures the stability and durability of the riding type mini-tiller during ploughing due to its excellent wear resistance, can bear the weight of the machine and ground pressure, and resist impact and friction. In addition, the dry land wheel provides stable support for the riding type mini-tiller, reduces energy consumption and improves ploughing efficiency.

[0004] In the related art, a walking wheel of a mini-tiller is disclosed in Chinese Utility Model Patent No. CN215321757U. The walking wheel includes a rim, multiple sets of spokes, a mounting seat and multiple sets of ground-inserting pieces. The ground-inserting pieces are rotated by the rim to insert into the ground to move the mini-tiller.

[0005] When the mini-tiller moves, the ground-inserting pieces are inserted into the ground, the rim contacts the ground, and the ground-inserting pieces rotate with the rim. However, for dry land with low water content, the ground-inserting pieces encounter large resistance when inserted into the ground. The contact between the ground-inserting pieces and the rim only has one mounting surface, so the ground-inserting pieces are prone to deformation. This not only reduces the service life of the walking wheel, but also reduces the working efficiency of the riding type mini-tiller. SUMMARY
