Description

Technical Field

[0001] The invention relates to the field of straw crushing, in particular to a crusher for potato straw and asparagus straw. Background Art

[0002] There are many ways to use potato straw and asparagus straw. Generally speaking, the straw can be directly crushed and returned to the field, which can increase soil organic matter, improve soil structure, and increase soil fertility. In addition, the straw can also be piled up and fermented to make compost and then used, which is also very effective. There are also some other methods, such as using it as feed, weaving processing, planting edible fungi, etc., which can also turn potato straw and asparagus straw into treasure.

[0003] In order to facilitate the crushing of straw, there are many types of straw crushers on the market. One type of crusher adopts a feeding roller group for feeding. The feeding roller group includes at least two feeding rollers. The straw enters between the two feeding rollers of the feeding roller group, so that the straw can be transmitted to the inside of the crusher through the two feeding rollers of the feeding roller group, and the straw can be automatically fed into the crusher. However, there is a characteristic that after the fed straw is pressed by the two feeding rollers and passes through the two feeding rollers, the straw at the rear is pressed, and the passed straw will be tilted upward or downward. On the one hand, this tilting is not conducive to the cutting and crushing of the straw. On the other hand, even if the tilted part of the straw can be cut and crushed, the end cutting positions of the structures at different positions are different during cutting due to the tilting of the ends, which will also cause the straw to have different shapes after cutting and crushing, resulting in inconsistency of the straw feed obtained after crushing, which is easy to affect the quality of the straw feed. Summary of the invention
