Technical Field

[0001] The utility model relates to the technical field of wheat straw materials, in particular to wheat straw crushing and processing equipment. Background Art

[0002] Wheat straw crushing equipment generally refers to equipment used to crush and break wheat straw and other crop straw. This equipment is usually used for the treatment and reuse of agricultural waste. It can break the straw into smaller particles for use in soil improvement, feed processing, biomass energy production and other fields. Traditional wheat straw crushing equipment usually uses a hammer crusher, which breaks the wheat straw by rotating and impacting the hammer head. There are some problems. During the crushing process, the traditional wheat straw crushing equipment may cause uneven crushing effect due to the impact method of the hammer head, and some wheat straw particles may be over-crushed. In addition, the hammer crusher will generate large noise and vibration during operation, which will have a certain impact on the surrounding environment and equipment structure. For this reason, we propose a wheat straw crushing equipment. Utility Model Content
