technical field

The utility model relates to a driving device, in particular to a walking driving device of a combine harvester.

Background technique

The front wheel of the existing combine harvester is a driving wheel, and the rear wheel is a guide wheel for controlling the walking direction of the harvester; this walking driving mechanism is easy to cause the harvester to sink into the soil when the soil is soft or the paddy field operation, so that the harvester cannot Carrying out the harvesting operation greatly reduces the operating efficiency of the harvester.

Contents of the invention

The technical problem to be solved by the utility model is to provide a walking driving device of the harvester which can also drive the rear wheel of the harvester.

In order to achieve the above object, the technical solution of the utility model is: a walking driving device of a harvester includes a front drive wheel, a rear guide wheel, and a main gearbox that provides driving force for the front drive wheel. Li's main gearbox is also provided with a power output shaft, which is connected with the power input shaft of the sub-transmission that can provide driving force for the rear guide wheels, and the power output shaft of the sub-transmission and the driving gearbox of the rear guide wheels pass through connected by a universal coupling; a clutch device is arranged in the auxiliary gearbox.

As an improvement, the clutch device is a sliding gear arranged on the power input shaft of the auxiliary transmission, and a shift fork controls the engagement or disconnection of the sliding gear.

As an improvement, the auxiliary gearbox includes a sliding gear arranged on the power input shaft of the auxiliary gearbox, a driven gear that can mesh with the sliding gear, a first bevel gear fixed on the same shaft as the driven gear, and fixed on The second bevel gear on the PTO shaft of the auxiliary transmission and meshing with the first bevel gear.

Due to the adoption of the above technical scheme, a walking drive device for a harvester includes a front drive wheel, a rear guide wheel, and a main gearbox that provides driving force for the front drive wheel. The main gearbox that provides drive force for the front drive wheel is also provided with There is a power output shaft, and the power output shaft is connected with the power input shaft of the sub-transmission that can provide driving force for the rear guide wheels, and the power output shaft of the sub-transmission is connected with the driving gearbox of the rear guide wheels through a universal coupling; The auxiliary gearbox is provided with a clutch device; when the rear guide wheel is required to participate in the drive, the power output shaft of the auxiliary gearbox is output through the clutch device and transmitted to the drive gearbox of the rear guide wheel, thus becoming Four-wheel drive mode, the utility model is simple in structure, flexible in operation, and can be suitable for various ground operations.
