Description

Drivable paddy field wheel on hard road surface

Technical Field

The utility model belongs to an agricultural production machinery field, concretely relates to agricultural machinery plants a can go to stereoplasm road surface paddy field wheel of using.

Background

The existing agricultural machine paddy field wheel has two types, namely a high-pattern tire and a tooth-inlaid iron wheel, and the two types of paddy field wheels can provide enough traction force during the working period of the paddy field wheel, simultaneously ensure that the agricultural machine has good adhesion performance in a paddy field with severe driving conditions, and greatly improve the farming efficiency and the planting quality. This is attributed to the large working area of the paddy field blades, which are greatly worn and damaged by the large extension dimension of the blades when running on hard roads, and the service life of the blades is reduced. The first existing solution is to temporarily assemble, disassemble and replace the road, which is time-consuming and labor-consuming. In the second solution, a special vehicle is adopted for consignment, and extra manpower and material resources are generated due to the large mass of the body of the agricultural machine.

Disclosure of Invention

The utility model provides a technical scheme that its technical problem adopted is: on the basis of the original large blade, protective measures are taken for the abrasion of the blade, and the two types of blade structures are alternately used. The spoke is connected with the rim and the hub, and the spoke is composed of an outer tube, a damping spring and a stroke rod and plays a role in damping and buffering. Novel paddy field wheel rim has upper and lower two-layer structure, and middle fretwork provides good working space for tire blade. The inclined blades and the vertical blades are alternately embedded on the supporting wheel rim, the top of each blade is provided with a large protection tire, and the two sides of the top of each blade are provided with small protection tires. The vertical blades play a main role in fixing and supporting the protective tire, and the inclined blades play an auxiliary role. When the agricultural machine runs in a paddy field, the inclined blades provide main traction. In a hard bump road section, the size protection tire is in direct contact with the ground, so that abrasion of the blades is avoided, and meanwhile, the damping spring at the spoke part plays a role in buffering, so that driving is stable, and abrasion to the protection tire is reduced.

The beneficial effects of the utility model are that, can realize that the agricultural machinery freely walks in paddy field and dry land, in the paddy field, because its double-deck hollow out construction, oblique blade and perpendicular blade alternate use, this kind of novel paddy field wheel can provide sufficient traction force, makes to plough and plants the high-efficient going on. The three outer protective tyres protect the blades, the damping springs at the spoke parts have a buffering effect, and the agricultural machine can run on cement roads, asphalt roads and field broken stone roads and cannot damage the novel paddy field wheel to influence the use performance of the novel paddy field wheel.

description of reference numerals: 1. the tire comprises a large protective tire, 2 small protective tires, 3 small protective tires, 4 vertical blades, 5 inclined blades, 6 hubs, 7 outer tubes, 8 damping springs, 9 travel rods, 10 supporting wheel rims, 11 steel rim cores, 12 rubber outer layers, 13 rubber outer layers and 14 steel tire cores.

Detailed Description

In fig. 1, the novel paddy field wheel comprises a hub 6, spokes and a rim, wherein the radius of the hub 6 is increased, so that three spokes separated by 120 degrees are fixed, and the mechanical structure of the novel paddy field wheel is more reliable. The spoke has three components, namely an outer tube 7, a damping spring 8 and a stroke rod 9. The body pressure elastically deforms the outer tube 7 by compressing the damper spring 8 fixed to the stroke rod 9, thereby relieving the impact. The rim adopts a double-layer structure, the middle of the rim is hollow, the lower layer is an elliptical ring supporting rim 10, and the upper layer is three protective tires 1, 2 and 3. The middle part is provided with an inclined blade 5 and a vertical blade 4, the top of the blade is shaped like a Chinese character 'shan', the two types of blades are alternately embedded on a supporting rim 10 at intervals of 20 degrees, and the number of the blades is 9. When the agricultural machine works in a paddy field, the inclined blades 5 provide main traction force, and the vertical blades 4 play an auxiliary role. The main function of the vertical blades 4 is to fix and support the shields 1, 2, 3 embedded at their top. When the road passes through a cement road, an asphalt road and a field gravel road, the protective tires 1, 2 and 3 at the outermost layers are in direct contact with the road surface to protect the blades 4 and 5.

In fig. 1, the oblique blades 5 are at an angle of 45 ° to the normal of the outer diameter of the supporting rim 10, and the vertical blades 4 are perpendicular to the normal of the outer diameter of the supporting rim. The large protective tire 1 is fixed at the tip of the blade, the small protective tires 2 and 3 are fixed at two sides of the top of the blade and are glued with each other, and the contact area between the vertical blade and the protective tires is large, so that the main supporting and fixing effects are achieved.

In fig. 2, the spoke part, the end of the outer tube 7 connected with the hub 6 is solid, the end connected with the damping spring 8 is hollow, enough space is left inside, and the damping spring 8 is in contact with the rubber outer layer 12 of the supporting rim 10.

In fig. 3, the stroke rod 9 is welded with the steel rim core 11, the steel rim core 11 is concave, and the outside of the steel rim core is covered with the rubber outer layer 12. The inner part of the protective tire is provided with steel wires 14, and the outer part of the protective tire is covered with a rubber outer layer 13.
