Technical Field

The invention relates to the field of plant protection machinery, in particular to a mechanical travelling wheel structure.

Background

When the plant protection machine walks between crops in a field, the plant protection machine needs to have good traffic capacity and reduce the rolled crops as much as possible so as to ensure smooth walking in the field and reduce the damage of the crops. The walking wheels of the existing plant protection machinery mainly have the following two types: 1. the tire type wheel has larger width, is suitable for walking in dry land and is easy to slip and sink in paddy field; 2. the tooth-shaped wheel is characterized in that a plurality of anti-skidding teeth are distributed on the outer circumference of the wheel, the width of the wheel is narrow, the anti-skidding teeth have certain ground scraping force, the slip is reduced, only the wheel is in contact with the ground easily in the walking process, the anti-skidding teeth are suspended, and the wheel is low in ground scraping force and easy to slip.
