[0021] The electrical components mentioned in this solution are all existing technologies, and their models are only one of them. As long as the electrical components can meet the requirements of this solution, they can be used.

[0022] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control. The specific work is as follows.

[0023] When in use, the corn thresher 1 and the dust suction fan 54 are turned on, and the corn is put into the corn thresher 1 from the feed port 2. After being processed by the corn thresher 1, the corn kernels will be discharged from the second discharge port 4, and the corn cobs will be discharged from the first discharge port 3. In this process, the dust and debris at the feed port 2, the first discharge port 3 and the second discharge port 4 can be adsorbed by the dust suction seat 58 through the dust suction fan 54 and enter the box body 51 through the four-way hose 57. The dust and debris in the box body 51 can be prevented from entering the dust suction fan 54 through the filter screen 55, thereby ensuring that the dust suction fan 54 can operate stably. The box body 51 can be cleaned by the dust collecting box 56. 1 to collect dust and debris; when it is necessary to regularly clean the box 51, it is only necessary to open the door 53, pull out the dust box 56 and pour out the dust inside, and the dust on the outer wall of the filter 55 can be cleaned by other cleaning tools such as a brush to avoid clogging; when it is necessary to change the position of the dust seat 58, it is only necessary to loosen the clip 59 from the outer wall of the feed port 2, the first discharge port 3 and the second discharge port 4 to complete the disassembly of the dust seat 58.
