According to the shelling principle of the scraper peanut shelling machine, it can be known that the peanuts pass through the collecting hopper, shelling box, screen grid, lower box outlet, sorting port, and peanut kernel collecting bucket in order from top to bottom, so the design The basis for the overall structure of the sheller comes out.
The design process is from top to bottom, starting from the collection of peanuts. The top is the collecting hopper. Below the collecting hopper is the shelling chamber. The collecting hopper can be designed as a whole with the shelling chamber. In the peanut shell removing chamber, the peanut must be impacted and squeezed by the scraper to remove the shell. Therefore, the scraper is designed to be placed in the shelling chamber. After the peanuts are shelled by the impact and squeeze of the scraper, they must pass through the screen grid at the bottom, so the grid can be designed as a semi-circular grid cage and fixed in the lower half. After passing through the grid, the peanuts fall through the outlet at the bottom. During the falling process, a blower inlet is designed to separate the peanut shells from the peanut kernels. Blow away, and the lighter peanut shell will bring the airflow blown by the fan into the peanut shell collection channel, and the bottom of the channel is designed at a certain angle. The separated peanut kernels fall down and fall into the peanut kernel collection channel. This channel and the bottom surface of the peanut shell collection channel are designed as a whole. This design allows the peanut kernels blown away by the wind to roll back by its own weight.
