It is processed from biological materials, animal and plant waste, and plant residues, eliminating toxic and harmful substances. It is rich in a large number of beneficial substances, including a variety of organic acids, peptides, and rich nutrients such as nitrogen, phosphorus, and potassium. It can not only provide comprehensive nutrition for crops, but also has a long fertilizer effect. It can increase and renew soil organic matter, promote microbial reproduction, improve the physical and chemical properties and biological activity of the soil. It is the main nutrient for green food production. There are many types of organic fertilizers, and straw is one of its important sources of raw materials. Using straw to produce organic fertilizer can maximize the application of straw, a green waste, and prevent air pollution caused by incineration. It is more scientific and environmentally friendly. To produce organic fertilizer using straw, the straw raw material must first be crushed.

[0003] Before making organic fertilizer, the straw needs to be crushed by a crusher. The straw can be crushed into smaller particles to facilitate subsequent mixing and fermentation operations. When the crusher crushes the straw and discharges it, dust will be generated at the discharge port, making the processing site inconvenient to clean and not conducive to the lung health of the workers. Therefore, a straw crusher with a dust suction structure is needed, which can filter and collect the dust at the straw discharge after crushing, so as to reduce the negative impact of dust in the straw crushing operation, thereby improving the sanitation and cleanliness of the processing site and protecting the lung health of the workers.
