Description

Technical Field

[0001] The utility model relates to the field of rice straw pretreatment devices, in particular to a rice straw pretreatment device used for processing rice straw bricks. Background Art

[0002] Rice straw bricks, also known as straw fiber concrete blocks, are a new type of building material. They are formed by inserting straw compressed blocks into hollow fiber concrete blocks. The straw fiber concrete blocks can not only improve the stress performance of concrete blocks, but also have certain economic and environmental benefits. Before the processing of rice straw bricks, the rice straw must be pretreated. Common pretreatment procedures include cutting, soaking, filtering and cleaning, dehydration, curing, and crushing.

[0003] In the prior art, the crushing process in the rice straw pretreatment process for processing rice straw bricks is usually carried out by a straw crusher. The straw crusher is designed with a feed port and a discharge port, and a crushing knife is designed in the machine body. The straw and rice straw are put into the straw crusher from the feed port, and the straw and rice straw are cut into fragments through the high-speed rotation of the crushing knife, and then discharged from the discharge port of the straw crusher. The straw crusher is used to crush the rice straw, and the rice straw can be crushed into very fine and uniform pieces, which is convenient for the subsequent process.

[0004] However, after the existing straw crusher crushes the rice straw and stalks, the rice straw stalks are ejected from the discharge port at a very fast speed, and the rice straw stalks are very light in texture, which causes a large amount of rice straw stalks to be dissipated with the air, which is not only easily inhaled by the on-site personnel into the mouth and nose to cause physical discomfort, but also causes a lot of waste.
