Description

Technical Field

[0001] The utility model relates to the technical field of straw collection and reuse, in particular to a crop straw collection and reuse device. Background Art

[0002] Straw is the general term for the stems and leaves (ears) of mature crops, usually wheat straw, corn straw, sorghum straw, rice straw, bean straw and other crops (usually coarse grains) left after harvesting seeds. Straw contains more than half of the products of crop photosynthesis and is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter. Straw can be collected and crushed for reuse, which can avoid waste of straw.

[0003] A crop waste fermentation device with the Chinese authorized announcement number CN214391598U improves the fermentation efficiency by setting up a crusher to crush the crop straw before putting it into a sealed fermentation chamber. By setting up a feeding preparation room, the entry of air is avoided during the feeding process of the crop waste, and the contact between the combustible gas in the fermentation chamber and the air is avoided, thereby improving the safety of the fermentation device.

[0004] There are still certain shortcomings in its use. When the straw is recycled, it is directly crushed. When there is dirt on the surface of the straw, the dirt cannot be removed from the surface of the straw, which will reduce the crushing rate of the straw. At the same time, when the straw is crushed, only a single crushing is performed, which will reduce the crushing quality of the straw, and there will be dead corners in the crushing, resulting in incomplete crushing of the straw, which reduces the effect of straw collection and reuse.
