Walking wheel structure for narrow-width micro-cultivator

Abstract

The invention discloses a walking wheel structure for a narrow-width micro-cultivator. Radial bosses are uniformly distributed on the outer circumferential surfaces of rims, side bosses are symmetrically arranged on the two sides of the middles of the radial bosses, the rims cover a steel skeleton, reinforcing structures uniformly distributed on the circumference are arranged on the steel skeleton, the reinforcing structures are spaced apart from the radial bosses, a hub is located at the center of the rims, a plurality of spokes uniformly distributed on the circumference are arranged betweenthe hub and the rims, and the spokes are of steel tube structures. The walking wheel structure can reduce the width of the rims, reduce the rolled area of the ground, increase road holding, avoid phenomena of idling and ridge running in arable land operation, and ensure easy operation, labor saving and high tillage efficiency. In addition, the rims cover the steel skeleton in combination with thereinforcing structures to prevent deformation or damage of the rims and facilitate connection with the spokes. The walking wheel structure has good supporting strength and is durable in harsh environments such as muddy roads.

Description

technical field [0001] The invention belongs to the technical field of miniature cultivators, and in particular relates to a walking wheel structure of a narrow-width microcultivator. Background technique [0002] With the vigorous support and development of agricultural mechanization, the use of tillage machines is becoming more and more extensive. Due to the characteristics of light weight, small size, simple structure, and convenient operation, the tiller is suitable for the cultivation of sloping land and small pieces of land in the vast hilly and mountainous areas of our country, and is deeply loved by the majority of users. [0003] At present, the walking wheels of micro tillage machines generally use wide rubber wheels, which have a large contact area with the ground and are easy to compact the ground, which is not conducive to the root growth of crops. Simultaneously, the gripping effect of the traveling wheels of the existing micro tillage machine is not good, and...

AI Technical Summary

Problems solved by technology

[0003] At present, the walking wheels of micro tillage machines generally use wide rubber wheels, which have a large contact area with the ground and are easy to compact the ground, which is not conducive to the root growth of crops.

At the same time, the walking wheels of the existing micro tillage machine do not have a good grip on the ground, and it is easy to idling and run away when the force is applied during the operation of the cultivated land, which limits the utilization rate of the micro tillage machine on sloping land

Some micro tillage machines add ground claws on the outer circumference of the walking wheel. Although the grip is increased, the ground claws are mostly wedge-shaped. On the one hand, they are prone to damage when encountering hard objects such as stones. resistance, making the operation more laborious, thus reducing the farming efficiency

[0004] Some micro tillage machine walking wheels adopt metal structure, including steel ring, hub installed in the steel ring and leaves installed on the periphery of the steel ring. It is easy to cause damage to the steel ring due to overload; and the processing technology of this all-metal structure travel wheel is complicated, the cost is high, and the relative rotation between the hub and the axle is easy to occur, and the reliability is poor
