A bionic duck paw inflatable paddy field tire

Abstract

The present invention relates to a bionic duck paw pneumatic paddy field tire, belonging to the technical field of agricultural machinery. The tire comprises a tire body provided with a tread, wherein the tread is provided with: a plurality of imitation duck paw-shaped pattern blocks evenly distributed on the tread, wherein the symmetry lines of the imitation duck paw-shaped pattern blocks coincide with the center line of the tread, and the imitation duck paw-shaped pattern blocks comprise: a duck phalangeal pattern arranged on the tread; and an interdigital webbed pneumatic pattern arranged on the duck phalangeal pattern and connected to the tread. The paddy field wheel of the present invention is the first to imitate the shape characteristics of a duck paw and is designed as a walking component of a paddy field weeder using bionic principles. The paddy field wheel imitates the shape curves of the duck paw phalanges and webbed feet, thereby increasing the tire's grip and reducing the degree of tire tread sinkage and the amount of mud on the tire. The webbed pattern is inflated internally, which can increase the contact area between the paddy field tire tread and the soil during travel, thereby reducing the degree of tire tread sinkage and the amount of mud on the tire.

Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a bionic duck-foot inflatable paddy field tire. Background Art

[0002] Paddy field wheels are the running gear mounted on the axles of wheeled agricultural machinery used for paddy field cultivation. Due to the unique characteristics of paddy field soil and the load-bearing and adhesion properties of the machinery, paddy field wheels must possess excellent grip and friction, while also minimizing excessive tread depression. Tires are round rubber products that roll around the wheel rim.

[0003] Currently, commonly used paddy field wheels include high-pattern rubber wheels and toothed iron wheels. High-pattern rubber tires can easily cause wet mud to embed into the gaps in the pattern, or even stick to the wheel hub and the rotating shaft, causing damage to the soil, affecting the maneuverability of the machine, thereby increasing energy consumption and reducing efficiency, and also easily damaging crops. Compared with dry fields, paddy fields have greater resistance to tires, so greater traction is required. The existing tread pattern design does not meet people's needs in terms of power, braking, and steering control, so it needs to be improved. Toothed iron wheels mostly use metal structures and are heavy, which not only increases the mechanical load but also reduces their maneuverability. Summary of the Invention

[0037] The tread 1 is arranged on the surface of the tire body 7, and has a number of duck-foot-shaped pattern blocks 8 distributed evenly thereon. The duck-foot-shaped pattern blocks 8 are made in the shape of a duck's foot and are used to rotate with the tire body 7 to contact the ground to generate grip and reduce the amount of tread sinkage.

[0038] When the present invention is actually used, the imitation duck-foot-shaped pattern block 8 rotates with the tire body 7 and contacts the ground. The imitation duck-foot-shaped pattern block 8 includes: a duck phalangeal pattern, which is arranged on the tread 1; an intertoe webbed inflatable pattern, which is arranged on the duck phalangeal pattern and connected to the tread 1; when the duck phalangeal pattern contacts the paddy field soil, it will generate greater grip, the intertoe webbed inflatable pattern is pressed and concave, and the gas in the cavity of the intertoe webbed inflatable pattern generates a force on the tire, reducing the amount of tread sinkage; since the imitation duck-foot-shaped pattern block 8 is made in the shape of a duck's foot, it can effectively increase the contact area between the tread of the paddy field tire and the soil, reduce the degree of tire tread sinkage, and reduce the amount of mud stuck to the tire, thereby increasing the tire's grip and making the tire better able to travel in the paddy field.

The surface curve curvature is 2.25-7.2mm, the second phalangeal pattern 2 is 8-12mm wide, 18-38mm high, 60-90mm long, and the top section curve curvature is 3.6-8.64mm. The third phalangeal pattern 4 is 5-10mm wide, 18-38mm high, 50-80mm long, and the top section curve curvature is 2.25-7.2mm. The symmetry line of the second phalangeal pattern 2 is opposite to the first phalangeal pattern 3. The deviation angle of the weighing line is 30-50 degrees, the deviation angle of the symmetry line of the third phalangeal pattern 4 and the symmetry line of the second phalangeal pattern 2 is 30-50 degrees, the first webbed inflatable pattern 5, the side length close to the first phalangeal pattern 3 is 40-55mm, the side length close to the second phalangeal pattern 2 is 48-65mm, the outer edge curve curvature is 30-60 degrees, the surface of the first webbed inflatable pattern 5 is horizontal, the pattern height is 10-30mm, the second webbed inflatable pattern In the pattern 6, the side length close to the second metatarsal pattern 2 is 40-55mm, the side length close to the third metatarsal pattern 4 is 48-65mm, the outer edge curve curvature is 30-60°, the surface of the second webbed inflatable pattern 6 is horizontal, and the pattern height is 10-30mm. This design can effectively increase the contact area between the tread of the paddy field tire and the soil, reduce the degree of tire tread sinkage, and reduce the amount of mud on the tire, thereby increasing the tire's grip and making the tire better able to travel in paddy fields.
