Abstract

The invention discloses a tractor, and relates to the technical field of agricultural machine manufacture. The tractor comprises an engine, wherein an output shaft of the engine is connected with a power distributing box between a front drive axle and a rear drive axle, a first output shaft of the power distributing box is connected with a first hydraulic pump, an output opening of the first hydraulic pump is communicated with an oil inlet of a first hydraulic motor through oil pipes and a first solenoid valve set, and the first hydraulic motor is connected with gear drive boxes which are mounted at both ends of an agricultural machine tool input shaft; a second output shaft of the power distributing box is connected with a second hydraulic pump, and an output opening of the second hydraulic pump is communicated with an oil inlet of a lifting cylinder of an agricultural machine tool hanging device through oil pipes and a second solenoid valve set; and a third output shaft of the power distributing box is connected with an input shaft of the front drive axle and an input shaft of the rear drive axle through a gearbox. Compared with the prior art, the tractor disclosed by the invention can solve the problems of poor power output performance and low production and operation efficiency in ploughing of the conventional tractor.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery manufacturing, in particular to a tractor with a hydraulic system and a mechanical system for power transmission. Background technique [0002] There is an existing figure 1 The wheeled tractor shown includes an axle box 105 connected to the engine 101 through a coupling 103 and a clutch 102 in sequence, and three power output units are arranged on the axle box 105, and one power output unit is driven by the rear axle. The wheel 104, one power output unit drives the agricultural implement 107 through the output shaft 106, and the one power output unit drives the three-point suspension device 108 connected to the agricultural implement through the lifting box 109. The power transmission device of this tractor has the following problems in the use process: the axle box with the three-way power output unit is limited by its structure, resulting in a small output torque of the output s...
