A straw crushing equipment for feed production

Abstract

The invention relates to a feed production straw crushing device, which comprises a base and a crushing device, and the crushing device is arranged on the upper surface of the base. The present invention can solve the following problems existing in the crushing of feed production straws: the straws of crops are long or short, hard or soft, thick or thin, and the existing straw crushing devices adopt all kinds of methods for crushing these straws. It is carried out in the way of direct feeding, which will make it difficult for the crushing device to crush some hard and thick straw, which will cause problems such as stuck and difficult operation of the straw crushing device, resulting in a decrease in the efficiency of straw crushing, which will affect the production efficiency of feed. , and the existing straw crushing device completes the crushing of the straw at one time, which will make the crushing effect of the straw worse, and the straw particles are too large, which will affect the quality of the feed when making feed.

Description

technical field [0001] The invention relates to the field of feed, in particular to straw crushing equipment for feed production. Background technique [0002] 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 (40%-60%), and contains lignin and so on. Although lignin and cellulose cannot be utilized by pigs and chickens, they can be absorbed and utilized by ruminant cattle, sheep and other livestock. Moreover, the recycled and crushed crop stalks are used as raw materials for making roughage, ...

AI Technical Summary

Problems solved by technology

[0003] At present, when crushing feed production straw, there are the following problems: the straw of crops is long or short, hard or soft, thick or thin, and the existing straw crushing devices are all directly fed to the crushing of these straws. This will make it difficult for the crushing device to crush some hard and thick straw, which will cause problems such as stuck and difficult operation of the straw crushing device, resulting in a decrease in the efficiency of straw crushing, which will affect the production efficiency of feed, and the existing The straw crushing device for the straw crushing is a crushing end, which will make the crushing effect of the straw worse, and the straw particles are too large, which will affect the quality of the feed when making feed
