Crushing device for recycling farmland straw

Abstract

The invention discloses a crushing device for recycling farmland straw. The device comprises an anti-skid sleeve, a first motor, a second motor, a first crushing device, a receiving tank, a bottom plate and a crushing box. The friction force between the hands of a user and the outer side of a handle is increased by arranging the anti-skid sleeve, so that the situation that the handle slides when the handle is held by the user is avoided. The first motor is used for rotating to drive a crushing blade on a crushing rotary shaft to rotate so as to crush the straw. The first crushing device is arranged, so that the aim of further crushing the straw is achieved, and the straw crushing effect is improved. The second motor rotates to drive a screw rod to rotate, so that a sliding block moves towards a first limiting plate on the screw rod, the receiving tank is further driven to move to the portion under a discharging pipe, the crushed straw falls into the receiving tank after passing throughthe discharging pipe, the crushed straw is collected, manual collection is not needed, and a large amount of manpower is saved.

Description

technical field [0001] The invention relates to a crushing device, in particular to a crushing device for recycling farmland straw. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. Usually refers to the remaining part of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops (usually coarse grains) after the seeds are harvested. 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 used by pigs and chickens, it can be absorbed and utilized by ruminant cattle, sheep and other livestock; [0003] Before recycling farmland straw, it is generally necessary to process the straw to a certain ex...

AI Technical Summary

Problems solved by technology

[0003] Before recycling farmland straw, it is generally necessary to process the straw to a certain extent. Crushing the straw is a very common processing method. The existing crushing device for recycling farmland straw has a poor crushing effect on the straw. The existing crushing device for farmland straw recycling does not have the function of automatically collecting the crushed straw, and the crushed straw needs to be collected manually, which wastes a lot of manpower. At the same time, the existing crushing device for farmland straw recycling is inconvenient to move , the portability is poor, and at the same time, the existing crushing device for farmland straw recycling does not have the function of extruding the crushed straw, which is not convenient for the storage and transportation of the crushed straw, and the practicability is not strong
