Power output device of subsoiling land preparation machine

Abstract

A power output device of a subsoiling land preparation machine comprises an engine, a transmission shaft, a transfer case, a front gearbox and a rear gearbox which are installed on a frame, an output shaft of the engine is connected with an input shaft of the transfer case, an output shaft of the transfer case is connected with an input shaft of the front gearbox, an output shaft of the front gearbox is connected with an input shaft of the rear gearbox through the transmission shaft, the engine transfers power to the front gearbox, the transmission shaft and the rear gearbox sequentially through the transfer case, and an output shaft of the rear gearbox transfers the power to an agricultural implement. By the aid of the power output device of the subsoiling land preparation machine, the variable-speed, variable-torque and interrupted power transfer can be achieved, the best match between the device and the engine can be achieved, the revolving speed and the torque of the whole vehicle are effectively controlled, the transmission system overload is prevented, the torque and revolving speed changing range for power output is large, the output power is strong, the power output device can be adapted to frequently-changing terrains, during driving, the power transfer is interrupted through neutral positions of the gearboxes to stop operation of the agricultural implement, the energy consumption is reduced, and the implement is protected.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a power output device for a subsoiling tillage machine. Background technique [0002] At present, most of the subsoiling and soil preparation machines produced at home and abroad are designed to be used as agricultural machinery, and there is no independent power output device in their structure. Operation. [0003] 1. The power output device of some domestic tillage and leveling machines is evolved from the power output device of the tractor, which is composed of the engine, clutch, transmission box assembly, transmission shaft, etc. In the transmission box assembly, the operation is mainly carried out by the separation and engagement of a clutch, so there are the following disadvantages: 1) It is easy to overload the transmission system, 2) When the power output and the travel drive device work at the same time, due to the clutch The torque that can be transmitted is limited, so wh...

Problems solved by technology

[0003] 1. The power output device of some domestic tillage and leveling machines is evolved from the power output device of the tractor, which is composed of the engine, clutch, transmission box assembly, transmission shaft, etc. In the transmission box assembly, the operation is mainly carried out by the separation and engagement of a clutch, so there are the following disadvantages: 1) It is easy to overload the transmission system, 2) When the power output and the travel drive device work at the same time, due to the clutch The torque that can be transmitted is limited, so when the speed of the machine changes sharply, the rotating parts in the entire transmission system will generate a large moment of inertia. This moment acts on the transmission system, which will cause its deformation or even damage. 3) This transmission system It is a mechanical transmission system, the operation is not very light, and it is easy to cause driver fatigue

[0004] 2. In addition, some of the cultivating and leveling machines produced have the same power output device as the chassis of the car. Chengli also relies on the separation and engagement of a clutch for operation, and there are also problems such as overload of the drive train and inconvenient operation, so it has a great impact on the power output performance of the cultivator.
