Variable wheel diameter mechanism

Abstract

The invention discloses a variable wheel diameter mechanism. The variable wheel diameter mechanism comprises a hub component (100), a driving shaft (200) and a tire component (300), wherein the hub component (100) is arranged on the driving shaft (200), the section of the hub component (100) is of a regular polygon structure, the tire component (300) comprises a plurality of tire blocks (302) which are equally divided, the number of the tire blocks (302) corresponds to the number of edges of the hub component (100), the outer sides of the tire blocks (302) are of arc structures, the inner sides of the tire blocks (302) are the mounting surfaces corresponding to the side surfaces of the hub component (100), and the tire blocks (302) are correspondingly mounted on the side surface of the corresponding side surfaces of the hub component (100) so as to form a round tire. According to the variable wheel diameter mechanism, the wheel diameter of a wheel can be changed in real time, the sliprate of the wheel is reduced, the slip of the wheel is reduced, the driving performance of a vehicle is improved, and the variable wheel diameter mechanism can adapt to various terrains and landforms.

Description

technical field [0001] The invention relates to a variable wheel diameter mechanism, specifically, a mechanism capable of changing the size of the wheel diameter in real time, so that the tire is not easy to slip and realizes stable walking. Background technique [0002] The ground plant protection sprayer has the advantages of high efficiency and convenience, and has made important contributions to the high yield and harvest of my country's grain. Due to the current centralized contiguous and standardized planting of farmland, in order to meet the needs, the ground plant protection equipment is developing in the direction of large-scale, resulting in a relatively large increase in the length of the sprayer's boom, the volume of the medicine box, and the weight of the whole machine. As a result, when the ground sprayer is working in the field, the chassis is easy to sink, the tires are easy to slip, and the slip rate increases, which affects the efficiency and quality of fie...

Due to the current centralized contiguous and standardized planting of farmland, in order to meet the needs, the ground plant protection equipment is developing in the direction of large-scale, resulting in a relatively large increase in the length of the sprayer's boom, the volume of the medicine box, and the weight of the whole machine. As a result, when the ground sprayer is working in the field, the chassis is easy to sink, the tires are easy to slip, and the slip rate increases, which affects the efficiency and quality of field work.

[0003] In view of the above problems, people have designed a boat tractor, which can solve this problem better, but becaus
