[0002] Agriculture refers to plants and animals. Forestry, animal husbandry, and planting are all considered agriculture. For example, when harvesting crops, agricultural machinery is needed to assist in the work, such as separating mature, dried wheat from other debris to improve the quality of the wheat.

[0003] After searching, a Chinese patent with publication number CN218167741U discloses a filter device for agricultural machinery operations. The technical point is: it solves the problem that when filtering and separating wheat, some of the separated debris can be recycled, such as wheat husks. If they are not classified and filtered, the production value of wheat will be reduced and production resources will be wasted.

[0004] However, in the above scheme, after the wheat is separated from the wheat husk, the wheat husk is light in weight and difficult to collect when it falls on the ground. The separated wheat husk cannot be collected quickly, resulting in inconvenience in transportation and collection.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
