[0002] Agriculture is an industry that uses the growth and development laws of plants and animals to obtain products through artificial cultivation. Agriculture belongs to the primary industry, and the science that studies agriculture is agronomy. The objects of agricultural labor are plants, animals and other organisms, and the products obtained come from the organisms themselves. Among them, straw is the general term for the stems and leaves of mature crops, usually referring to the remaining part of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops after harvesting seeds. More than half of the products of crop photosynthesis exist in straw. Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter. It is a multi-purpose renewable biological resource that can be used as feed for ruminants, cattle, sheep and other livestock. Since straw burning will aggravate environmental pollution, most of them currently use straw crushers to effectively crush the straw before using it.
[0003] In the working process of the existing crushing device, the straw is placed in a crushing chamber equipped with crushing blades, and the straw is crushed by the high-speed rotating crushing blades to obtain crushed materials of required fineness. However, since there is only a single crushing rod and crushing blades inside the crushing device, and the straw can only be crushed by the unidirectional rotating crushing blades, the straw crushing fineness does not meet the standard, and secondary crushing is often required, which reduces the crushing efficiency. Therefore, we provide a high-efficiency crushing device for agricultural use. Utility Model Content
