A crushing device for a combine harvester

Abstract

The invention discloses a crushing device of a combined harvester. The device comprises a barrel body, a rotating shaft, a driving device, cutter bodies and a cutter mounting mechanism, wherein the rotating shaft is arranged at the axial center of the barrel body; the driving device is used for driving the rotating shaft to rotate, and the cutter mounting mechanism is used for mounting the cutterbodies on the rotating shaft. The crushing device has an excellent continuous operation capability and effectively relieves or avoids blockage through reverse folding of some cutter bodies under an extreme condition of blockage or impending blockage, and therefore the rotating shaft can carry other cutter bodies for continuous rotation operation. Meanwhile, damage to the rotating shaft, the driving device and the like because of the blockage is avoided.

Description

technical field [0001] The invention relates to the field of harvesters, and particularly provides a crushing device for a combine harvester. Background technique [0002] In order to better degrade the straw after returning to the field, the harvester needs to first crush the straw through the crushing device and then discharge it to the field. For example, the patent application No. 201710760987.0 discloses a straw crushing device for a combine harvester, which is crushed by the intermeshing of horizontally arranged rollers with blades. Although the device has a large crushing force, due to the long straw, the straw enters the crushing The speed of the device is fast and the posture is diverse, which can easily cause the crushing device to be unable to quickly crush the incoming straw, and it is very easy to cause the accumulation of straw materials. If the vertically arranged rotating shaft drives the horizontally arranged blades to rotate for crushing, although the crus...

Problems solved by technology

For example, the patent application No. 201710760987.0 discloses a straw crushing device for a combine harvester, which is crushed by means of horizontally arranged rollers with blades meshing with each other. Although the crushing force of this device is large, due to the long straw, the straw will enter the crushing process. The speed of the device is fast and the postures are diverse, which can easily cause the crushing device to be unable to quickly crush the incoming straw, and it is easy to cause the straw materials to accumulate

If the rotating shaft arranged vertically drives the blades arranged horizontally to rotate for crushing, although the crushing speed is fast, once it is blocked by straw, the rotating shaft cannot drive the blades to rotate, the crushing operation cannot be continued, and even the rotating shaft and the driving device will be damaged.
