Description

Technical Field

[0001] The invention relates to the technical field of straw processing, in particular to a straw crushing device for recycling and processing agricultural waste. Background Art

[0002] Straw refers to the remaining stems and leaves of rice, wheat, corn and other gramineous crops after threshing. When the straw is crushed, the straw enters the crushing chamber through the feed hopper. There may be solid particles such as stones between the straw. These objects may be trapped between the straw when the straw is collected in the field. These stones and metal objects will damage the knife group after entering the crushing chamber through the feed hopper. The existing patent announcement number CN118077439B discloses a biomass straw processing device, which allows the straw to slide down the feed hopper, and the stones carried between the straws will be shaken off during the movement of the straws, and the shaken stones will fall to the bottom of the feed hopper, pass through the mesh plate into the inner side of the storage slot during the movement, and then cooperate with the auger to push the stones and metal objects out of the feed hopper to prevent the stones from entering the crushing chamber and causing accidents. However, it is not easy to break up the straw during the movement of the straw, making it difficult to expose the stones, and there is still a risk of subsequent crushing. In addition, the straw here is easily blocked during the filtering process, resulting in very unsmooth material discharge.

[0003] Based on this, a straw crushing device for agricultural waste recycling and processing is now provided, which can eliminate the disadvantages of existing devices. Summary of the invention
