Narrow rim structure

Abstract

The invention discloses a narrow rim structure. The width of a rim body ranges from 50 mm to 70 mm, radial bosses are evenly distributed on the outer circumferential face of the rim body, edge bossesare symmetrically arranged on the two sides of the middle portion of each radial boss, the edge bosses, the side faces of the rim body and the radial bosses are connected into a whole, the outer end faces of the edge bosses and the outer end faces of the radial bosses are located on the same circumferential face, and the inner end faces of the edge bosses and the inner circumferential face of therim body are located on the same circumference; and a steel framework is coated with the rim body, and multiple evenly-distributed connecting sleeves are arranged on the inner circumferential face ofthe steel framework. By the adoption of the structure, the width of a rim is reduced, meanwhile, the radial bosses and the edge bosses are additionally arranged, the rolled region of the ground can bereduced, the ground holding force is increased, the idling and ridge deviation phenomena generated in land cultivation operation are prevented, it is guaranteed that operation is convenient and quickand saves labor, and cultivation efficiency is high. In addition, the steel framework achieving a lining effect is coated, so that the rim is prevented from being deformed or damaged, and the rim canbe conveniently connected with a wheel arm.

Description

technical field [0001] The invention belongs to the technical field of miniature cultivators, and in particular relates to a narrow rim of a microcultivator traveling wheel. 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 it is eas...

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
