Straw crusher

Abstract

The invention discloses a straw crusher which comprises slide ways, a crushing cylinder and a bottom plate, two parallel fixing plates are welded to the top of the bottom plate, the fixing plates are perpendicular to the bottom plate, annular slide ways are arranged at the tops of the fixing plates, sliding grooves are formed in the inner sides of the annular slide ways, and the crushing cylinder is horizontally arranged on the inner side between the annular slide ways on the two sides. A first conveying belt, a second conveying belt and a third conveying belt are arranged and matched with the effect of conveying crushed straw generated by rotation of the crushing cylinder, and in the straw crushing process, the crushed straw which does not reach the aperture of a sieve hole can move to the end, close to the third conveying belt, in the crushing cylinder, fall on the third conveying belt, is conveyed through the third conveying belt, the first conveying belt and the second conveying belt in sequence and then enters the crushing cylinder again to be crushed, the straw crushing effect is good, the automation degree is higher, and the crushed straw is not prone to accumulation.

Description

technical field [0001] The invention relates to the technical field of straw crushing, in particular to a straw crushing machine. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops, usually referring to the remaining parts of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops (usually coarse grains) after harvesting seeds, the product of photosynthesis of crops More than half of them exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable biological resource. Straw is also a roughage, characterized by high crude fiber content 30%-40%), and contains lignin, etc. Although lignocellulose cannot be used by pigs and chickens, it can be absorbed and utilized by ruminant cattle, sheep and other livestock. Straw can be used after crushing. [0003] At present, in the process of crushing straw with the existing straw grinde...
