The corn kernels reach the roughing screen 12 through the feeding hole 11, and the first motor 3 drives the roughing screen 12 to vibrate when working. The screening sieve 12 vibrates, and the corn kernels can pass through the screening sieve 12 to remove larger impurities such as stones and debris.

A first impurity outlet 123 is fixed at one end of the screen far away from the feed inlet 11, and impurities screened by the roughing screen 12 can be discharged through the first impurity outlet 123. A collecting box 13 is fixed in the machine case 1, and the collecting box 13 is positioned at the lower side of the roughing screen 12. The kernel of corn after screening through roughing screen cloth 12 can fall to collection box 13, and the kernel of corn at this moment is not of uniform size, still includes flat grain except that full kernel of corn. The collecting box 13 is fixed with a first discharge port 124.

The lower side of the first discharge port 124 is provided with a fine selection screen 14 placed obliquely. As shown in fig. 2 and fig. 3, an elongated spherical protrusion 141 is fixed at one end of the fine selection screen 14 close to the first motor 3, an elongated spherical chute 142 is arranged on the inner wall of the casing 1, and the chute 142 extends inwards from the edge of the casing 1 and penetrates through the casing at the side, and the direction of the chute is consistent with the direction of the protrusion 141. The protrusion 141 can slide in the sliding groove 142 along the sliding groove 142, and two ends of the sliding groove 142 are provided with openings, so that an operator can slide the fine selection screen 141 out of the edge of the sliding groove 142 and remove the fine selection screen 141 for replacement. As shown in fig. 1, a second pad 143 is disposed on an inner wall of the housing 1 on one side of the first outlet 123, a spring 144 is fixed on the second pad 143, and a spring hook 1441 is fixed on the spring 144. The second pad 143 and the spring 144 with spring hook 1441 function to fixedly attach the sifter screen 14. The end of the sifting screen 14 near the first outlet 123 is connected to a spring 144. As shown in fig. 2 and 4, the lower side of the refining screen 14 is provided with a first projection 145, the first projection 145 is provided with a hole 1451, and the spring hook 1441 is hooked in the hole 1451 of the first projection 145, so that the connection to the refining screen 14 is realized. The spring 144 may return the sizing screen 14 to its original position during vibration.

As shown in fig. 1, a vibration device is fixed to a lower side of the second pad 143. The vibrating device comprises a second motor 4, and a second eccentric disc 41 is fixed on an output shaft of the second motor 4. When the output shaft of the second motor 4 rotates, the second eccentric disc 41 is driven to rotate. The second eccentric disc 41 is abutted against the lower surface of the fine selection screen 14, and the fine selection screen 14 is driven to vibrate up and down when the second eccentric disc 41 rotates. A second discharge port 146 is provided at one side of the first motor 3, and the second discharge port 146 is positioned at an upper side of the protrusion 141 of the fine selection screen 14. An inclined drainage plate 15 is fixed on the lower side of the fine selection screen 14, the drainage plate 15 is arranged to be narrow at the lower side, and a third discharge hole 16 is formed in the narrow part. The corn coming from the first outlet 124 falls onto the sifting screen 14 and the undersized, flat grains are dropped by vibration onto the lower drainage plate 15 and collected through the third outlet 16. The filled kernels are collected through a second outlet 146.

Because there are many varieties of corn, the size of the plump grains to be sorted out is different among different varieties of corn. Thus, full and flat corn kernels can be sorted from different corn varieties by replacing the sifting screen 14 with sifting screens of different sizes.

As shown in fig. 5 and 6, the casing 1 can be opened at a side perpendicular to the plane of the sifting screen 14. The cabinet 1 has a cabinet door 17 fixed to one side thereof, the cabinet door 17 is rotatably connected to one side thereof by a hinge 175, and the other side thereof is provided with a receptacle 171. A second protrusion 172 is fixed on the side of the chassis 1 away from the hinge 175, the second protrusion 172 can be inserted into the insertion hole 171, a pin hole 173 is fixed in the second protrusion 172, and a pin 174 can be inserted into the pin hole 173 to block the chassis door 17 to fix the chassis door 17. When the cabinet door 17 needs to be opened, the pin 174 is pulled out to open the cabinet door 17.

When it is desired to replace the refining screen 14, the housing door 17 is opened, the spring hook 1441 is first detached from the first projection 145 of the refining screen 14, the refining screen 14 is pulled out from the side of the housing door 17, the desired refining screen 14 projection is inserted into the chute 142 from the edge of the housing 1, and the refining screen 14 is pushed inward. After the replacement is completed, the cabinet door 17 is closed and the pin 174 is inserted.

The implementation principle of the embodiment is as follows: corn is poured into the feed inlet 11, the corn is vibrated by the roughing screen 12, and large impurities such as stones and chips are discharged through the first impurity outlet 123. The corn kernels with different sizes mixed with the shrivelled kernels enter the fine screening screen 14 through the first discharge hole 124, and the full corn kernels are discharged and collected through the second discharge hole 146 through the vibration of the fine screening screen 14. The shrivelled grains pass through the sifting screen 14 onto the flow-guide plate 15 and are discharged through a third discharge opening 16 for collection.
