Air mixed with dirt enters the dirt pocket 38 via the suction fan 36 and the dirt is trapped by the side walls of the dirt pocket 38. The air passes through the side walls of the dust bag 38 and is effectively collected to prevent contamination by the dust being discharged into the air.

The implementation principle of the wheat gravity cleaning and sorting machine in the embodiment of the application is as follows: the worker pours the wheat original seeds into the dust removing box 31 from the feeding bin 32, after the dust removing operation, the wheat original seeds enter the machine case 1, the wheat original seeds fall onto the cleaning plate 213, meanwhile, the vibration motor 224 is started, the vibration motor vibrates to drive the bottom plate 221 to move up and down on the guide column 222, further, the material collecting plate 211, the cleaning plate 213 and the collecting plate 216 are driven to vibrate synchronously, and because the material collecting plate 211, the cleaning plate 213 and the collecting plate 216 are all arranged in an inclined mode, the wheat original seeds move towards the opening close to the machine case 1 in the vibration process, in the movement process, the wheat original seeds with smaller particle diameters fall onto the material collecting plate 211 through the filtering holes 2131 in the cleaning plate 213, the purpose of preliminary screening is achieved, the wheat original seeds with poor quality vibrate synchronously along with the vibration impurities and the cleaning plate 213, the wheat original seeds with relatively small quality move to a relatively higher height, and further move to the collecting plate 216, and the collecting plate 216 moves out of the collecting plate 216 along with the vibration of the collecting plate 216, so that the cleaning effect on the wheat stock seeds is increased, the quality of the cleaned and selected wheat stock seeds is improved, and the defects that when the quality of the wheat stock seeds is too small, longer time is needed for vibration separation, and the working efficiency is lower are overcome.

When the quality screening scope of wheat stock seed need be changed, staff's accessible is changed different cleaning plate 213, and the filtration hole 2131 diameter on the cleaning plate 213 of difference is different, and then can filter out the wheat stock seed of different particle diameters, and the accessible is adjusted the quality scope of the wheat stock seed of separation by adjusting the interval between collecting plate 216 and the cleaning plate 213, the effectual convenience of changing the quality of cleaning the wheat stock seed that has improved.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
