Large vertical straw pulverizer

Abstract

The invention provides a large vertical straw pulverizer which is efficient and high in automation degree and can realize continuous production. The large vertical straw pulverizer comprises a base, a feeding device arranged above the base, a primary pulverizing device and a secondary pulverizing device, the feeding device comprises an outer barrel, an inner barrel arranged in the outer barrel and a power unit for driving the inner barrel to rotate; the primary pulverizing device comprises a primary pulverizing chamber provided with a feeding hole, a primary rotating shaft assembly arranged in the primary pulverizing chamber and a primary motor for driving the primary rotating shaft assembly to rotate; the secondary pulverizing device comprises a secondary pulverizing chamber, a secondary rotating shaft assembly arranged in the secondary pulverizing chamber and a secondary motor for driving the secondary rotating shaft assembly to rotate; and the primary pulverizing chamber and the second pulverizing chamber are connected in series and arranged in the base, and the primary rotating shaft assembly and the secondary rotating shaft assembly are opposite in rotation direction.

Description

technical field [0001] The invention relates to the related technical field of agricultural equipment, in particular to a large vertical straw grinder. Background technique [0002] Straw mainly includes field crop straw, greenhouse vegetable straw, etc. The use of modern fertilizers has greatly reduced the demand for fertilizers made from straw in agriculture, and the disposal of straw has become a major problem. If the straw is not disposed of in time, it will affect the sowing of the next season's crops. This has become the objective reason for the repeated prohibition of large-scale straw burning. Burning straw not only poses a great safety hazard, but also causes serious air pollution, which is an act explicitly prohibited by the state. [0003] At the same time, straw is an important raw material for making organic fertilizer and biogas. In order to achieve the best use effect, it must be crushed. However, the current straw grinder has the disadvantages of low effici...

Problems solved by technology

Burning straw not only poses a great safety hazard, but also causes serious air pollution, which is an act explicitly prohibited by the state.

[0003] At the same time, straw is an important raw material for making organic fertilizer and biogas. In order to achieve the best use effect, it must be crushed. However, the current straw grinder has the disadvantages of low efficiency, time-consuming and labor-intensive production. Efficiency cannot meet the preparation needs of large-scale organic fertilizer and biogas plants. There are many places where manual participation is required, and the labor intensity is high and it is easy to cause personal injury.
