Abstract

The invention discloses a power output device of a tractor and relates to the technical field of tractor manufacturing. The power output device comprises an engine, an agricultural implement and an agricultural implement hanging device, the agricultural implement hanging device is connected with a lift cylinder, an oil inlet of the lift cylinder is communicated with an oil outlet of a first hydraulic pump through a first solenoid valve set, an input shaft of the agricultural implement is connected with hydraulic motors through gear transmission cases arranged at two ends thereof, and oil inlets of the hydraulic motors are communicated with an oil outlet of a second hydraulic pump through a second solenoid valve set. The first hydraulic pump and the second hydraulic pump are both connected with an engine through a transfer case. Compared with the prior art, the power output device has the advantage that the problem of low production and operation efficiency of existing tractors can be solved.

Description

technical field [0001] The invention relates to the technical field of tractor manufacturing, in particular to a tractor power output device. 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. This kind of 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 the output torque of the output shaft connected with the agricultural implement is small, causing the agricultural implement to ...
