[0017] In this embodiment: the working bin 1 is used to support and connect various components, so that the screening of corn kernels in corn cobs can be completed through the cooperation of other components. The sealing cover 2 detachably connected to the top of the working bin 1 is used to seal the inside of the working bin 1, so that when the corn kernels are screened, the supporting seat 11 fixed on the inner side of the working bin 1 is used to support the screening disk 3 and the blocking cover 31, and the sealing cover 2 can fix components such as the transmission seat 21. A driven gear 22 is meshed on the inner side of the transmission seat 21, and a connecting rod 23 is fixedly connected to the bottom end of the driven gear 22, so that when the staff places the sealing cover 2 on the top of the working bin 1, the driven gear 22 can be located on the inner side of the screening disk 3, and the screening disk 3 is used to place the corn cobs and corn kernels that need to be screened. The corn cob and the corn kernels are carried by the screen disc 3. A driving motor is fixed at the bottom of the working bin 1, and the output end of the driving motor is connected to the screening disc 3, so that the driving motor can drive the screening disc 3 to rotate, so that the corn cobs and corn kernels located at the top of the screening disc 3 can move, and the screening disc 3 is provided with screening holes inside, so that when the corn kernels touch the screening holes opened inside the screening disc 3, they can fall to the bottom of the screening disc 3, thereby being separated from the corn cobs. A blocking cover 31 is provided on the top of the screening disc 3 for rotation, and the blocking cover 31 is used to block the corn cobs, so as to ensure that the corn cobs can be stably located at the top of the screening disc 3 for screening operation. A driving rod 32 is fixed on the top of the screening disc 3, and the driving rod 32 can drive the driven gear 22 through the transmission seat 21, so that the screening disc 3 rotates. When the corn cob is moved, the connecting rod 23 will rotate around the outer side of the driving rod 32, and the driving rod 32 and the connecting rod 23 rotate in opposite directions. A plurality of adapter rods 24 are fixed to the outer side of the connecting rod 23, and a plurality of extension rods 33 are fixed to the driving rod 32, so that when the connecting rod 23 and the driving rod 32 rotate, a force can be applied to the corn cob through the adapter rod 24 and the extension rod 33 to make it move, thereby avoiding the accumulation of the corn cob and allowing the corn kernels mixed in the corn cob to fall to the top of the screening plate 3 and contact the holes opened inside the screening plate 3. A lifting plate 4 is provided under the screening plate 3. When the screening plate 3 rotates, the lifting plate 4 will be driven to move synchronously through other components. An electric push rod is fixed to the inner wall of the bottom end of the working bin 1. The rotating ring 42 is connected, and the rotating ring 42 can rotate relative to the lifting plate 4, so that when the lifting plate 4 rotates with the screening plate 3, it will not drive the rotating ring 42 and the electric push rod to move synchronously, but the electric push rod can drive the rotating ring 42 and the lifting plate 4 to move vertically, so that when the lifting plate 4 can move vertically upward, it will drive the alignment rod 41 fixed on the top to move synchronously. Since the lifting plate 4 and the screening plate 3 move synchronously, the alignment rod 41 and the hole opened inside the screening plate 3 are continuously corresponding. The alignment rod 41 will be inserted into the hole during movement and continue to move upward. Since the size difference between the corn cob and the corn kernel is large, several alignment rods 41 will drive the corn cob located at the top of the screening plate 3 to move vertically upward.The corn kernels can fall between the alignment rods 41. At this time, the adaptor rod 24 and the extension rod 33 will continue to contact the corn cob and drive the corn cob to move, so that the corn kernels between the corn cobs can fall to the top of the screening plate 3. Since the adaptor rod 24 and the extension rod 33 rotate in opposite directions, the adaptor rod 24 and the extension rod 33 will apply forces in two directions to the corn cob, so that the stirring effect on the corn cob can be guaranteed. The corn kernels that fall on the top of the screening plate 3 will rotate with the screening plate 3, so that the corn kernels enter the clearance cavity 43 opened inside the alignment rod 41, and then fall to the bottom of the screening plate 3 through the clearance cavity 43, completing the screening operation of the corn kernels.
[0018] A synchronization rod 34 is fixedly connected to the outer side of the screening disc 3, and the lifting disc 4 slides on the inner side of the synchronization rod 34; the synchronization rod 34 fixed on the outer side of the screening disc 3 is used to connect the screening disc 3 and the lifting disc 4, so that when the screening disc 3 rotates, the lifting disc 4 can be driven to move synchronously through the synchronization rod 34, so that the position of the alignment rod 41 fixed on the top of the lifting disc 4 continues to correspond to the hole opened inside the screening disc 3, and the lifting disc 4 slides on the inner side of the synchronization rod 34, so that when the lifting disc 4 rotates with the screening disc 3, it can be driven by the rotating ring 42 to move vertically, so that the alignment rod 41 can be inserted into the hole opened inside the screening disc 3, and the corn cob on the top of the screening disc 3 is lifted to prevent the corn cob from blocking the hole.
[0019] The outer side of the blocking cover 31 is fixedly connected to a limit block 35, and the limit block 35 is engaged with the top of the support seat 11; the limit block 35 fixed on the outer side of the blocking cover 31 is used to fix the position of the blocking cover 31, so that when the screening disc 3 rotates, it will not drive the blocking cover 31 to move synchronously, to prevent the adapter rod 24 from driving the corn cob to move and contact the blocking cover 31, and the blocking cover 31 applies a force to the corn cob, causing the corn cob to detach from the inner side of the blocking cover 31, so that the blocking cover 31 can stably complete the blocking work of the corn cob.
[0020] A driving tooth 36 is fixedly connected to the outer side of the driving rod 32, and the driving tooth 36 is meshed with the driven gear 22; the driving tooth 36 fixed on the outer side of the driving rod 32 is used to drive the driven gear 22 to move, and the driving tooth 36 is meshed with the driven gear 22, so that when the driving rod 32 rotates, the driving tooth 36 can be driven to move synchronously, and the driving tooth 36 can drive the driven gear 22 to rotate when rotating, so that the driven gear 22 drives the connecting rod 23 and the adapter rod 24 to move synchronously, so that the connecting rod 23 can rotate with the driving rod 32, and the rotation direction of the connecting rod 23 and the driving rod 32 is opposite, thereby ensuring the degree of stirring of the corn cob.
[0021] An auxiliary block 44 is fixedly connected to the outer side of the lifting plate 4, and a guide groove 37 is opened inside the synchronization rod 34, and the auxiliary block 44 slides inside the guide groove 37; the auxiliary block 44 fixed on the outer side of the lifting plate 4 is used to guide the sliding of the lifting plate 4, and the auxiliary block 44 slides in the guide groove 37 opened inside the synchronization rod 34, so that the lifting plate 4 will be guided by the guide groove 37 when it moves vertically, thereby avoiding the lifting plate 4 from being offset during the vertical movement.
[0022] The working principle and use process of the utility model are as follows: when the staff needs to screen the corn kernels in the corn cob, the staff can place the mixture of the corn cob and the corn kernels on the top of the screening plate 3, and then the staff can place the blocking cover plate 2 on the top of the working bin 1. When the staff places the blocking cover plate 2 on the top of the working bin 1, the staff can mesh the active tooth 36 fixed on the outside of the driving rod 32 with the driven gear 22, and then the staff can start the driving motor installed on the inner wall of the bottom end of the working bin 1, and then the driving motor will drive the screening plate 3 to perform screening. The sieve plate 3 rotates, and the driving rod 32 and the driving tooth 36 rotate when the sieve plate 3 rotates, so that the driving tooth 36 can drive the driven gear 22 to rotate, and the driven gear 22 drives the synchronous movement when it rotates, and the connecting rod 23 rotates in the opposite direction to the driving rod 32. When the connecting rod 23 and the driving rod 32 rotate, they will respectively drive the adapting rod 24 and the extending rod 33 to rotate, and the adapting rod 24 and the extending rod 33 will contact the corn cob and exert opposite forces on the corn cob, so that the corn cob moves above the sieve plate 3, so that the corn mixed in the corn cob can be removed. The rice grains can fall on the top of the screening plate 3 and touch the holes opened inside the screening plate 3, so that the corn grains can fall to the bottom of the screening plate 3 through the holes. While the screening plate 3 is moving, it will drive the lifting plate 4 to rotate synchronously through the synchronization rod 34, so that the alignment rod 41 fixed on the top of the lifting plate 4 can continue to correspond to the holes opened inside the screening plate 3. At this time, the electric push rod installed on the inner wall of the bottom end of the working bin 1 will drive the lifting plate 4 to move vertically upward through the rotating ring 42, so that the lifting plate 4 drives the alignment rod 41 to pass through the hole and insert into the inside of the screening plate 3. The alignment rod 41 is The vertical movement will drive the corn cob at the top of the screening disk 3 to be lifted, so as to prevent the corn kernels from being continuously located at the top of the screening disk 3 and blocking the holes. At this time, when the corn kernels are separated from the corn cobs by the adaptor rod 24 and the extension rod 33 when stirring the corn cobs, they can reach the top of the screening disk 3. The screening disk 3 will drive the corn kernels to move when rotating, so that the corn kernels enter the make way cavity 43 opened in the alignment rod 41. The corn kernels entering the make way cavity 43 will be separated from the top of the screening disk 3 by the guidance of the make way cavity 43, thereby completing the screening operation of the corn kernels.
