[0002] Straw refers to the stalks left after the crops are harvested, including the stalks of wheat, rice, corn, cotton, etc. Straw is usually left in the fields during agricultural production, and can also be used as a biomass resource to produce pellet fuel, feed, etc.
[0003] A straw crusher is a device used to crush straw and other crop straw into granular materials suitable for subsequent use. The structure of a straw crusher usually includes the following components: a feed hopper, a crushing device, a transmission device, a frame, and a discharge device, which facilitates better crushing of the straw.
[0004] The existing straw crushers still have the following problems: when crushing straw, the existing straw crushers mostly use a conveying device to directly transport the straw into the crushing barrel, and use the crushing knife inside the crushing barrel to cooperate with the crushing motor to crush the straw. However, crushing the straw in this way can easily lead to uneven distribution of the straw, affecting the crushing efficiency, causing some straw to fail to be fully crushed, and directly sending the straw into the crushing barrel for crushing may cause the crushing knife to be subjected to greater impact and wear, shortening the service life of the equipment and greatly increasing the energy consumption required for crushing, causing great trouble to the use;
[0005] Secondly, most of the existing straw crushers can only crush the straw. It is very inconvenient to collect the sizes of particles after the straw is crushed, and the size of the particles is difficult to fully control and screen, which causes many inconveniences in actual use.
[0006] In view of this, we propose a straw crusher with adjustable particle size. Utility Model Content
