Background

The straw is a general term of stem leaf (ear) part of mature crops. Typically refers to the remainder of the wheat, rice, corn, potatoes, oilseed rape, cotton, sugar cane and other crops (typically roughages) after harvesting the seed. More than half of the products of crop photosynthesis exist in the straws, and the straws are rich in nitrogen, phosphorus, potassium, calcium, magnesium, organic matters and the like, are multipurpose renewable biological resources, and are also coarse feeds. It features high coarse fibre content (30-40%), and lignin content. Although the lignocellulose cannot be utilized by pigs and chickens, the lignocellulose can be absorbed and utilized by livestock such as ruminants, cattle and sheep.

The most common treatment mode of the prior straw is incineration, however, the straw is incinerated to cause the straw with potential nutrition to be wasted, and on the other hand, smoke generated by combustion can cause great pollution to air, so that the straw is crushed into fine particles by a crusher in the current straw treatment mode to be absorbed and utilized by cattle, sheep and other livestock. The existing straw crusher usually comprises a crushing box, and when straws are sent into the crushing box to be crushed, crushed straw particles can flow out of a sieve plate at an outlet. But the crushing quality of the existing crusher is low, the straw is crushed not thoroughly enough, and the crushed straw can usually comprise more incompletely crushed straw, so that the cattle, sheep and other livestock can not well meet the user demand because the cattle, sheep and other livestock can cause damage to organs such as intestines and stomach when eating.
