[0002] The screening device is also called a separation device, a screening machine, etc. With the characteristic of long-time operation, the screening device is convenient for carrying out persistent screening operations on apples. When storing and picking apples, a screening device is needed to screen the apples, so as to facilitate the subsequent storage and transportation of apples of different specifications, and to facilitate the screening operations on apples of different specifications. In daily use, a screening device for apples is needed to carry out classification screening operations on apples.

[0003] The existing screening devices do not have the function of adjusting the installation height of the device according to the use requirements during use. It is necessary to rely on external equipment to adjust the installation height position of the device, which reduces the convenience of adjusting the installation height position of the device. The existing solutions are to equip electrical equipment such as threaded foot rods, telescopic rods, and electric rods to adjust the installation height position of the device. However, when using the device, there are still problems. It does not have an automatic cleaning function and cannot clean the apples during the screening operation, resulting in the need to clean the apples after the screening operation, complicating the cleaning process of the apples and at the same time reducing the cleanliness of the apple surface. At the same time, it does not have an automatic dust removal function and cannot collect the dust and impurities generated during the screening of apples. The dust and impurities floating in the air are likely to cause environmental pollution and reduce the environmental protection effect of using the device. Therefore, a screening device for apples needs to be designed. Summary of the Utility Model
