Description
Technical Field
[0001] The utility model relates to the technical field of rice straw crushing, and more specifically, to a rice straw crushing device. Background Art
[0002] Rice stalks are a type of straw, which is a general term for the stems and leaves (ears) of mature crops, usually referring to the remaining parts of wheat, rice, corn, rapeseed, cotton, sugarcane and other crops (usually coarse grains) after harvesting seeds. Straws contain more than half of the products of crop photosynthesis, rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable biological resource and also a roughage. When rice stalks are processed into roughage, they need to be crushed. The existing crusher uses a crushing knife in a box to rotate at high speed, so that the multiple blades of the crushing knife cut the rice stalks. However, the rice stalks are easy to adhere to and entangle on the rotating shaft of the crushing knife after getting wet. Since the blades of the crushing knife cannot contact the rice stalks, the rice stalks are easy to accumulate on the rotating shaft of the crushing knife, which seriously affects the crushing efficiency of the crushing device. In addition, a large amount of dust will be generated during the crushing process of the rice stalks. To solve the above problems, we have introduced the following device. Utility Model Content

The dust generated by the rice straw during the crushing process first enters the first duct 31 through the material filter plate 29, and larger materials cannot pass through the material filter plate 29. Then the dust enters the dust removal box 32 through the first duct 31, and is then blocked by the dust filter cover 33. The dust is retained in the dust removal box 32, thereby processing the dust generated by the rice straw during the crushing process. After the processing is completed, people can open the door panel 40 through the handle 41 to clean the dust collected inside the dust removal box 32.
