However, the problem of paddy rice working machines in hilly and mountainous areas has become a difficult problem that hinders the industrialization of agriculture, and farmers have strong demands for high-performance paddy rice tillage machines.
Currently, for some extremely complex and severe terrain environments, such as the ground with deep snow, extremely soft soil, desert, grasslands with high weeds and the like, the trafficability of tires is far inferior to that of a crawler belt. This is because the ground contact area of the track is large, greatly improving the grip and traction of the tracked vehicle; in addition, the pressure of the crawler belt to the ground is far smaller than the pressure of the wheels to the ground, so that the vehicle can easily overcome various complex and severe terrain environments.
The two triangular crawler belts of the existing triangular crawler belt type driving mechanism cannot rotate along with the driving axle alone, namely, the driving mechanism does not have a terrain-imitating walking function, when the vehicle runs on complex road conditions of over-ridge and uneven height, due to the fact that stable inclination angles of the crawler belts cannot be guaranteed, the triangular crawler belt wheels cannot be attached to and grabbed on the ground flexibly, so that the trafficability of the vehicle body under the condition of operation in fields and the like is poor, more fuel oil is further consumed to change the trafficability, and meanwhile, due to the fact that the vehicle cannot grab the ground well, a tractor with the conventional triangular crawler belt is prone to overturning, and therefore driving safety is affected.
