Description

Paddy field agricultural tire

Technical Field

The utility model belongs to the technical field of the rubber matrix, especially, relate to a paddy field agricultural tire.

Background

A paddy field agricultural tire is a special driving tire for a paddy field, and a tread of the paddy field agricultural tire is provided with a plurality of raised pattern blocks. The water field has the advantages that the supporting pressure for the tires is very small due to the sparse and heavy soil, and meanwhile, the plastic deformation of the soil is very large. When the tire runs on a road surface, the traction force is equal to the friction force of the contact part of the tire and the road surface, and when the tire runs on soft paddy fields, the blocks of the paddy field agricultural tire are pressed into soil, and besides the friction force of the tread, the blocks of the tire press the soil from the direction opposite to the moving direction, so that the soil generates reaction force opposite to the moving direction to agricultural equipment. The tangential traction of the tire therefore consists of the resultant of all the friction forces of the tire in contact with the soil and the reaction forces generated when the tire presses the soil in the opposite direction of the tractor's motion.

The protruding height of the pattern block of the agricultural tire for the paddy field is generally 70-95 mm, and is 2.5-2.8 times higher than that of a common R-1 dry field tire with the same specification, so that the pattern block of the tire is in more sufficient contact with soil in the paddy field, the pattern block of the existing agricultural tire for the paddy field is high, the pattern saturation is low, and the thickness of a tire shoulder is higher than the design thickness of the tire shoulder of the common tire; meanwhile, because the tire shoulder is too thick, heat is easily generated, the root of the pattern block at the tire shoulder is more easily adhered with mud and caked, the self-cleaning property of the tire is influenced, and the problem that the shoulder is easily emptied and the like is easily generated at the heated tire shoulder. Therefore, the agricultural tire for the paddy field is designed.

It should be noted that the information disclosed in the above background section is only for enhancement of understanding of the background of the present disclosure, and thus may include information that does not constitute prior art.
