Abstract

The invention discloses a paddy filed tractor. The paddy filed tractor comprises a rack, wherein a driving bridge and a driven bridge are arranged on the rack, two driving wheels of the driving bridge are respectively connected with a gearbox through a half shaft, and the driving wheel and a driven wheel which are arranged at the same side are in linkage. By the aid of the four wheel drive, the wheel pressure of a single wheel is effectively reduced, and a walking type farm machine can be prevented from falling in the paddy field. Besides, two driving wheels are respectively connected with the gearbox through the half shaft, the driving wheel and the driven wheel which are arranged at the same side are in linkage, the problem of power distribution of the four wheel drive is solved, a tractor body turns round a wheel which serves as input power through transmission of unilateral power, the turning method of the four wheel drive walking type farm machine is greatly improved, and the turning radius of the machine is reduced.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a four-wheel tractor suitable for paddy field operations. Background technique [0002] Walk-behind agricultural machinery is generally supported by the weight of the walking wheel, which is pushed forward by people or driven by the engine, and the working parts are driven by the engine to perform cutting and filling operations. When working in the paddy field, because the supporting force of the soil in the paddy field is small, the walking wheels tend to sink, causing the hand-held agricultural machinery to fail to work normally. Especially two-wheeled hand-held agricultural machinery, because the wheel pressure is too large, it is easier to fall into the paddy field. With the four-wheel drive walking agricultural machinery, the wheel pressure of each wheel is reduced, and the sinking phenomenon in the paddy field is not as obvious as that of the two-wheel walking agricultural machin...
