Since the threaded ring 405 is rotationally connected to the thread on the connecting pipe 702, when the threaded ring 405 rotates, it can drive the connecting pipe 702 to move up and down, thereby realizing the installation and disassembly of the connecting pipe 702 and the dust extraction pipe 403, making it convenient to disassemble and assemble the dust collection component 7 on the outer box 4, so as to clean the dust inside the dust collection component 7.

[0030] The working principle of this utility model:

[0031] When it is necessary to screen corn hybrid seeds, first place a plurality of screening drawers 101 and collecting drawers 102 in the screening box 1, and move the movable plate 301 in the direction of the spring 1 302 so that the card block also moves. At this time, it does not affect the sliding placement of the screening drawer 101 and the collecting drawer 102 in the screening box 1. After the screening drawer 101 and the collecting drawer 102 slide to a suitable position, the movable plate 301 can be loosened. The elastic force of the spring 1 302 will cause the movable plate 301 to move upward, so that the card block can also move, so that the card block is engaged with the card slot, thereby restricting the screening drawer 101 and the collecting drawer 102 in the screening box 1.

[0032] Then, the dust extractor 701, the motor 2 603, and the motor 1 204 can be started at the same time. The dust extractor 701 can draw the dust in the outer box 4 from the dust extraction pipe 403 into the dust extractor 701, and enter the collection drawer 2 705 in the collection box 704 through the guide tube 703; the motor 2 603 can drive the rotating rod 601 to rotate, thereby driving the spiral conveying sheet 602 to rotate. After the corn hybrid seeds are placed in the feed port 401, the corn hybrid seeds can be transported to the discharge port 402, and the dust raised during the transportation will also be collected by the dust collector 701. The collecting assembly 7 collects the hybrid corn seeds; the hybrid corn seeds enter the screening box 1 through the discharge port 402. Since the motor 204 can drive the wheel 203 to rotate, the vibration rod 205 can be driven to rotate, so that the screening box 1 vibrates up and down in the outer box 4, and then cooperates with the screening drawer 101 to screen the hybrid corn seeds according to size, so that the hybrid corn seeds of different sizes are respectively in several screening drawers 101 and the collecting drawer 102. After the screening is completed, the dust collector 701, the motor 2 603, and the motor 1 204 can be turned off.

[0033] Then the above operation on the movable plate 301 can be repeated to make the card block leave the card slot. At this time, the screening drawer 101 and the collecting drawer 102 can be removed from the screening box 1 to take out the screened corn hybrid seeds.

[0034] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
