Hybrid rice seed cleaning machine suitable for mixed sowing and mixed harvesting

The hybrid rice seed cleaning and sorting machine comprises a machine shell, a material storage cavity and a cleaning and sorting cavity which are adjacent to each other are formed in the machine shell, a pushing mechanism used for pushing seeds to enter the cleaning and sorting cavity is installed in the material storage cavity, and a screening mechanism used for separating the seeds according to the particle size is installed in the cleaning and sorting cavity. According to the seed cleaning machine, the material storage cavity is formed in the machine shell, a part of seeds to be cleaned can be stored in the material storage cavity, then the seeds are fed into the cleaning cavity at the preset speed through the pushing mechanism installed in the material storage cavity to be screened, and therefore continuous manual material adding is not needed, and manpower is saved. By arranging the screening mechanism, male parent seeds and female parent seeds obtained through mixed sowing and mixed harvesting can be d
