Technical Field

The invention belongs to the technical field of agricultural machinery, and particularly relates to a retractable tractor paddy field antiskid dual-purpose tire.

Background

In many areas in south, paddy fields and dry lands are old, so that more functional requirements are provided for tractors for assisting in ploughing, and the tractors can adapt to paddy field and dry land operation. The tractor suitable for dry land is easy to slip and sink mud when working in paddy field. Similarly, tractors suitable for paddy field work are not suitable for dry field work.

Disclosure of Invention

The technical problem of the invention is mainly solved by the following technical scheme:

a retractable tractor paddy field antiskid dual-purpose tire is characterized by comprising a rubber wheel outer tire, a wheel hub, a plurality of driving systems arranged on the rubber wheel outer tire, and a driving wheel plate assembly connected with the driving systems; the driving system comprises a hydraulic oil cylinder assembly, and a driving wheel plate of the driving wheel plate assembly is connected with a piston rod of the hydraulic oil cylinder assembly and can rotate along the radial direction of the rubber wheel cover tire under the driving of the hydraulic oil cylinder assembly.

Preferably, the driving system further comprises an oil distribution fixing seat fixed on an automobile axle, the oil distribution fixing seat is connected with a driving hub shaft disc through a supporting bearing, the driving hub shaft disc is connected with the rubber wheel cover tire, and the driving wheel plate assembly is fixed on the driving hub shaft disc.

Preferably, the driving wheel plate assembly further comprises a driving wheel connecting seat fixed on a driving wheel hub, and the driving wheel plate for the paddy field is connected with the driving wheel connecting seat through a pin shaft and can rotate around a pin shaft hole of the driving wheel connecting seat.

Preferably, the hydraulic cylinder subassembly includes hydraulic cylinder, and hydraulic cylinder's fixed orifices also is connected with the drive wheel connecting seat, can rotate around its round pin shaft hole, and paddy field drive wheel board is connected with the pin hub for hydraulic cylinder to can radially rotate along the rubber wheel cover tire under hydraulic cylinder's drive, drive when hydraulic cylinder shrink paddy field drive wheel board and rotate the back and contract inside the rubber wheel cover tire, drive the paddy field drive wheel board when hydraulic cylinder stretches out and stretch out outside the rubber wheel cover tire after rotating.

Preferably, the number of the driving systems is 6, the driving systems are circumferentially arranged on the rubber wheel outer tire, and the number of the driving wheel plate assemblies is 6, and the driving wheel plate assemblies are matched with the driving systems and circumferentially arranged on the rubber wheel outer tire.

Preferably, the paddy field driving wheel plate is L-shaped, one end of the paddy field driving wheel plate is hinged to the driving wheel connecting seat and is connected with the driving wheel connecting seat through a pin shaft, and the top end of a piston rod of the hydraulic oil cylinder is hinged to the inflection point of the L-shaped paddy field driving wheel plate.

Therefore, the invention has the following advantages: (1) the tyre of the invention is dual-purpose for paddy and dry land, and can switch two farming states in dry land and paddy field. When the dry land is used for farming, the driving wheel plate of the paddy field is retracted into the wheel hub, so that the transfer and the walking of the tires are not influenced; when the paddy field is cultivated, the driving wheel plate of the paddy field extends out, the driving force is increased, and the slipping during cultivation is avoided. (2) The hydraulic oil cylinder is adopted to drive the driving wheel of the paddy field, and the two farming states can be flexibly switched. (3) The invention increases the adhesive force with soil and increases the driving force after adding a plurality of paddy field driving wheel plates, thereby reducing or even avoiding the phenomena of skidding and mud sinking and leading the machine to be capable of adapting to more working conditions.
