[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

The side away from each other, and each sliding protrusion 14 is slidably connected in the adjacent special-shaped holes 16.
[0025] In this embodiment, the special-shaped holes 16 include vertical holes, horizontal holes and arc-shaped holes, and the bottom of the arc-shaped holes is connected to the vertical holes, and the top of the arc-shaped holes is connected to the horizontal holes. The setting of the special-shaped holes 16 allows the upper hopper 12 to automatically tilt when it rises to a high place to achieve material pouring.
[0026] In this embodiment, a same rotating shaft 21 is rotatably connected between the two ends of the inner side of the shell 4 through bearings, and a plurality of fixed rings 22 are fixedly sleeved at equal distances on the circumferential surface of the rotating shaft 21. The outer surface of each fixed ring 22 is rotatably connected to three rotating rods 23 at equal distances, and the other end of each rotating rod 23 is fixedly connected to a counterweight block 24. The arrangement of the rotating rod 23 and the counterweight block 24 makes the corn detachment speed faster.
[0027] In this embodiment, a discharge hopper 18 is fixedly connected to the bottom of the shell 4, and an arc-shaped metal screen 17 is fixedly connected to the bottom inner side of the shell 4. A discharge port matched with the arc-shaped metal screen 17 is opened on one side of the lower end of the shell 4, and a guide plate 19 is fixedly connected to the outer side of the discharge port. A motor 20 is fixedly connected to the outer side of the lower end of the shell 4, and the output end of the motor 20 passes through the shell 4 and is fixedly connected to one end of the rotating shaft 21. The arc-shaped metal screen 17 can allow the detached corn to enter the discharge hopper 18 and be discharged, and the corn cobs are discharged from the guide plate 19.
[0028] In this embodiment, a mounting plate 25 is fixedly connected to the outer side of the higher end of the shell 4, and a reducer 26 is fixedly connected to one side of the mounting plate 25. The input end of the reducer 26 passes through the shell 4 and is fixedly connected to one end of the rotating shaft 21. The output end of the reducer 26 is fixedly connected to a second bevel gear 27, and the second bevel gear 27 is meshed with the first bevel gear 10. Through the arrangement of the reducer 26 and the second bevel gear 27, the rotation speed of the motor 20 is greatly reduced, so that the reciprocating lifting speed of the upper hopper 12 is moderate and not too fast, which is convenient for the user to put corn into the upper hopper 12 when the upper hopper 12 drops to the lowest level.
[0029] In this embodiment, a bending baffle 33 is fixedly connected to the top of the shell 4 near the feeding port 401, and fixed blocks 28 are fixedly connected on both sides of the bending baffle 33. Limiting rods 29 are slidably sleeved on the two fixing blocks 28. Round holes adapted to the limiting rods 29 are opened on the two fixing blocks 28. The ends of the two limiting rods 29 near the upper hopper 12 are fixedly connected to the same first protective net 30. The two limiting rods 29 are located between the first protective net 30 and the fixing blocks 28 and are sleeved with springs 3 1, the other ends of the two limit rods 29 are fixedly connected to the limit blocks, and the two ends of the first protective net 30 close to the fixed block 28 are fixedly connected to the second protective net 32. Through the arrangement of the first protective net 30 and the second protective net 32, when the loading hopper 12 is away from the loading port 401, the first protective net 30 and the second protective net 32 automatically block the loading port 401, and the corn will not splash from the loading port 401. The four corners at the bottom of the bottom plate 1 are fixedly connected with universal wheels 101.
[0030] Working principle: When in use, connect the household power supply and supply power to the motor 20, the motor 20 can drive the rotating shaft 21 to start rotating, so that the multiple fixed rings 22 start rotating with the rotating rod 23 and the counterweight block 24 under the action of centrifugal force. The rotating shaft 21 is decelerated by the reducer 26, which can greatly reduce the high-speed rotation of the motor 20, so that the reciprocating screw rod 9 starts to rotate slowly, which will drive the U-shaped lifting frame 8 to move up and down. In the process of the upper hopper 12 rising, the sliding protrusion 14 slides along the special-shaped hole 16. When the sliding protrusion 14 slides to the horizontal hole with the special-shaped hole 16, due to the continued rise of the U-shaped lifting frame 8, the upper hopper 12 begins to tilt toward one side of the feeding port 401. When the upper hopper 12 is filled with corn, it can be achieved. The corn is automatically sent from the bottom to the loading port 401, which reduces the work that the user has to overcome gravity to do on the corn, greatly saving the user's physical strength. Through the reciprocating lifting of the loading hopper 12, the user can intermittently put the corn into the loading hopper 12 located at the bottom. When the loading hopper 12 is dumped, the front end of the loading hopper 12 will push the first protective net 30, so that the first protective net 30 and the second protective net 32 move, and compress the spring 31, so that the corn can smoothly enter the shell 4 for disengagement. When the loading hopper 12 descends, under the action of the spring 31, the first protective net 30 and the second protective net 32 are reset, so that the corn will not splash out from the loading port 401 when threshing. The threshed corn is discharged from the discharge hopper 18, and the corn cob comes out through the guide plate 19.
