Description

An agricultural straw grinder

technical field

The utility model relates to the technical field of agricultural equipment, in particular to an agricultural straw grinder.

Background technique

Straw is the general term for the stems and leaves (ears) of mature crops. It usually refers to the remaining part of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops (usually coarse grains) after harvesting the 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 (30%-40%), and contains lignin and so on. Although lignocellulose cannot be utilized by pigs and chickens, it can be absorbed and utilized by ruminant cattle, sheep and other livestock.

In the past, the most common treatment method for straw was incineration. However, on the one hand, the straw with potential nutrition will be wasted by incineration. On the other hand, the smoke generated by combustion will cause great pollution to the air. The straw is crushed into fine particles by a grinder for absorption and utilization by cattle, sheep and other livestock. Existing straw grinders usually include a crushing box, and when the straw is sent into the crushing box for crushing, the crushed straw particles will flow out from the sieve plate at the outlet at the same time. However, the crushing quality of existing pulverizers is low, and the crushing of straw is not thorough enough. The crushed straw material usually includes more incompletely crushed straw material, which will cause damage to the stomach and other organs when cattle, sheep and other livestock eat. , can not well meet the needs of users.
