The broken shell kernels are small in size and fall directly from the vibrating screen 3 onto the receiving tray 4. Due to the inclined setting of the vibrating screen 3 and the dropping tray 4, the unbroken sour jujube kernels slide from the outlet end of the vibrating screen 3 and fall into the first receiving hopper 5, and the broken shell kernels slide from the outlet of the receiving tray 4 and fall into the second receiving hopper 6.

[0018] The feeding mechanism includes a storage bin 7, a first elevator 8 arranged on the storage bin 7, a first drop hopper 9 arranged below the discharge end of the first elevator 8, a first feeding pipe 10 arranged at the discharge end of the first drop hopper 9, a distribution hopper 11 arranged at the discharge end of the first feeding pipe 10, a first storage hopper 12 arranged below the first receiving hopper 5, a second elevator 13 arranged on the first storage hopper 12, a second drop hopper 14 arranged at the discharge end of the second elevator 13, a second feeding pipe 15 arranged at the discharge end of the second drop hopper 14, and a A second storage hopper 16 is disposed on one side of the frame 1, and a third elevator 17 is disposed on the second storage hopper 16. The lower end of the sub-hopper 11 is provided with two drop openings and are respectively connected to the feed ends of the first two groups of shell breakers 2. The discharge ends of the first receiving hoppers 5 of the first two groups of shell breakers 2 are connected to the feed ends of the first storage hopper 12. The second feeding pipe 15 is connected to the feed end of the third group of shell breakers 2. The discharge end of the first receiving hopper 5 of the third group of shell breakers 2 is connected to the feed end of the second storage hopper 16. The discharge end of the third elevator 17 extends into the storage bin 7.

The sub-hopper 11 is located lower than the first drop hopper 9. The sour jujube kernels slide from the first drop hopper 9 along the first feeding pipe 10 and fall into the sub-hopper 11. The sub-hopper 11 is located above the shelling machine 2. The sour jujube kernels in the sub-hopper 11 automatically fall into the feeding ports of the first two groups of shelling machines 2 for shelling. After shelling, the material is discharged from the lower end of the shelling machine 2 and falls on the vibrating screen 3. After screening by the vibrating screen 3, the unbroken sour jujube kernels slide from the outlet end of the vibrating screen 3 and fall into the first receiving hopper 5. The broken shell kernels fall on the receiving tray 4 and slide from the outlet of the receiving tray 4 to fall into the second receiving hopper 6. The unbroken sour jujube kernels of the first two groups of shelling machines 2 all fall into the first storage hopper 1 from the first receiving hopper 5. 2, the second elevator 13 lifts the sour jujube kernels in the first storage hopper 12 and transports them to the second drop hopper 14, the sour jujube kernels fall from the second drop hopper 14 along the second feeding pipe 15 into the feeding port of the third group of shelling machines 2, and are crushed again by the third group of shelling machines 2. After being screened by the vibrating screen 3 and the receiving tray 4, the unbroken sour jujube kernels fall from the outlet end of the vibrating screen 3 into the second storage hopper 16, and are then lifted and transported to the storage bin 7 by the third elevator 17 for cyclic crushing. The design of the feeding mechanism can automatically feed and screen, and transport the unbroken sour jujube kernels back to the storage bin 7 for cyclic crushing, which greatly improves the feeding efficiency while screening.
