Description

Technical Field

[0001] This utility model relates to the technical field of wheat straw crushing equipment, and in particular to a wheat harvester straw crushing device. Background Technology

[0002] After wheat is harvested, a large amount of straw remains. In order to improve soil fertility, the straw usually needs to be crushed and returned to the field.

[0003] Existing wheat straw crushing equipment, such as the Chinese utility model patent CN220935760U (authorization announcement number: A wheat harvester straw crushing device), represents a class of prior art whose main structure includes a vertical cutter, a horizontal cutter, and an air pump. The vertical cutter and the horizontal cutter work together to crush the wheat straw, and the air pump blows the vertical cutter, the horizontal cutter, and the crushed wheat straw to reduce the straw jamming and increase the discharge speed of the wheat straw.

[0004] However, the existing technology and equipment still have the following problems when in use: when processing wet straw with high moisture content, the existing machines are prone to sticking and tangling with the blades, resulting in low work efficiency. Furthermore, the existing machines have a relatively complex structure and are not easy to maintain. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a straw crushing device for wheat harvesters. By setting up a cutting device, a cleaning device, and a crushing device, it reduces the number of times the blades cut the straw and cleans the blades in a timely manner. At the same time, it crushes the straw by throwing and smashing, reducing the phenomenon of wet straw sticking to and tangling the blades, thus improving work efficiency. Furthermore, by setting up a cutting device, a cleaning device, and a crushing device, it uses a simple machine structure with fewer transmission parts to crush the straw, thereby improving the machine's ease of maintenance.

[0006] This utility model discloses a straw crushing device for a wheat harvester, comprising a machine body; and further comprising a cutting device, a cleaning device, a crushing device, and a spreading device. The cutting device, cleaning device, and crushing device are all mounted on the machine body, and the spreading device is mounted on the crushing device. The machine body provides support, the cutting device cuts the wheat straw, the cleaning device accelerates the discharge of the cut wheat straw, the crushing device crushes the cut wheat straw, and the spreading device increases the spreading speed of the crushed wheat straw.

The motor is fixedly installed on one side of the reducer and provides power to the rotating shaft through the reducer. The power provided by the motor drives the rotating shaft to rotate the cutters, and the rotation of the cutters, in conjunction with the cutting cylinder, cuts the wheat straw into segments.
