technical field

The invention relates to the field of agricultural machinery, in particular to a high-efficiency straw cutting and crushing device.

Background technique

Straw is the general term for the stems and leaves (ears) of mature crops. Usually refers to the remaining parts of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops after harvesting seeds. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable biological resource, and straw is also a roughage. It is characterized by high crude fiber content and lignin. Although lignocellulose cannot be utilized by pigs and chickens, it can be absorbed and utilized by ruminant cattle, sheep and other livestock.

In order to protect the environment and recycle resources, the country has now banned the burning of straw. It is a good way to crush and reuse straw. The crushing efficiency of ordinary crushing devices is not high, and the crushing effect is not good. It is difficult for the crushed straw particles to reach the feed. The standard of preparation, and because many straws have high crude fiber content and long length, it is inconvenient to crush directly, and it is easy to cause the crushing blade or rotating shaft to be stuck, which will have an adverse effect on the crushing device.
