Vehicle wheel device and agricultural machine using vehicle wheel device

Abstract

The invention provides a vehicle wheel device and an agricultural machine using the vehicle wheel device, and belongs to the technical field of agricultural machinery. The vehicle wheel device comprises a vehicle wheel. The vehicle wheel comprises a wheel rim, a wheel hub and spokes. The vehicle wheel is connected with a vehicle frame. Two or more check blocks are distributed on the inner side of the wheel rim. Each check block is divided into a working part and an adjusting part; and the working part comprises a first working part and a second working part, the first working part and the second working part can freely rotate around the axes parallel to the diameter of the vehicle wheel, and the first working part is engaged with the second working part through a pair of external gears. A baffle is arranged on the side face of the vehicle wheel, is fixed to the vehicle frame and makes contact with the adjusting parts. When the vehicle wheel rotates around the vehicle frame, the adjusting parts move along the baffle and drive the working parts to rotate under the action of the baffle. The vehicle wheel device is simple in structure, and travelling of the vehicle wheel in water fields or mires is facilitated.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a wheel device and an agricultural machine using the wheel device. Background technique [0002] When agricultural machinery walks in paddy fields or muddy swamps, in order to increase the contact area, a number of teeth with a certain area are generally added to the outside of the rim of the wheel to help the wheel move forward. However, in the first half of the contact with mud and water, the large-area gear teeth can indeed play a very good role in boosting due to the large contact area, but in the second half of the contact with mud and water, the same wheel However, the teeth hinder the movement of the wheel. The larger the area, the more obvious the obstruction effect. On the other hand, as the wheel rotates, the teeth can easily bring out mud or weeds and attach them to the wheel, thereby increasing the size of the wheel. The size and weight are not conducive to the ...

However, in the first half of the contact with mud and water, the large-area gear teeth can indeed play a very good role in boosting due to the large contact area, but in the second half of the contact with mud and water, the same wheel However, the teeth hinder the movement of the wheel. The larger the area, the more obvious the obstruction effect. On the other hand, as the wheel rotates, the teeth can easily bring out mud or weeds and attach them to the wheel, thereby increasing the size of the wheel. The volume and weight are not conducive to the continuous progress of the wheels
