Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a knife sharpening device for a chopping knife of a chopping and kneading machine. Background Art

[0002] Traditional silage is prepared by transversely chopping corn stalks and then storing and fermenting them. However, the silage structure formed by this process has low digestibility and poor palatability, which greatly affects the feeding speed of livestock. The chopping device is the shutdown component of the chopping and kneading machine. The sharpness of the chopping device's blade has an important impact on the equipment's operating quality and work efficiency. At the same time, the chopping device is under high-intensity operation, and the cutting edge of the chopping knife is very easy to become blunt, which not only affects the chopping quality, but also increases the energy consumption of the equipment accordingly. Therefore, it is necessary to sharpen the knife frequently to maintain the sharpness of the chopping knife. At present, in addition to large-scale silage harvesting machinery, existing chopping and kneading machines usually use manual sharpening. Manual sharpening requires manual operation, which is time-consuming and labor-intensive. At the same time, the grinding amount is difficult to control, which destroys the dynamic balance of the chopping roller, thereby affecting the service life of the equipment. Therefore, it is urgent to optimize the chopping knife sharpening device of the chopping and kneading machine to solve the difficulties in daily sharpening of the equipment. Utility Model Content
