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 composed of a first part and a second part, a gap is formed between the first part and the second part, and the first part and the second part can rotate relatively. The vehicle wheel device further comprises a guide rail and adjusting rods. The guide rail is fixedly connected with the vehicle frame. One ends of the adjusting rods are connected with the guide rail, and the other ends of the adjusting rods are provided with adjusting parts. The adjusting parts are gradually broadened from outside to inside in the radial direction of the vehicle wheel and are aligned to the gaps between the first parts and the second parts of the check blocks. 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
