[0019] As shown in the attached Figures 1 - 3 figure, the utility model discloses a rotary feeding device for a corn husker, which comprises a turntable 1, a root-opening drill bit 23 fixedly arranged on the bottom surface of the turntable 1, a root sleeve 15 located in front of the root-opening drill bit 23 and slidably mounted on the turntable 1, a roller 19 mounted on the root sleeve 15, and a guide rail located above the turntable 1. The root-opening drill bit 23 and the root sleeve 15 rotate together with the turntable 1. The guide rail is located above the turntable 1 and is fixed in position. The roller 19 cooperates with the guide rail, and the guide rail gradually offsets outwards. Under the guiding action of the guide rail, the root sleeve 15 gradually moves outwards, away from the root-opening drill bit 23, so as to push the corn on the root-opening drill bit 23 down to realize feeding.

[0020] According to actual processing requirements, the guide rail can be divided into two sections. The first section includes a first guide rail 6, and the second section includes a second guide rail 7 and a third guide rail corresponding to the second guide rail 7. The first guide rail 6 is approximately arc-shaped. When the roller 19 cooperates with the first guide rail 6, the positions of the root sleeve 15 and the root-opening drill bit 23 remain unchanged. The second guide rail 7 and the third guide rail are adapted in shape, and both gradually offset outwards. The third guide rail is located inside the second guide rail 7. The roller 19 is cooperatively installed at a position between the second guide rail 7 and the third guide rail. Under the action of the second and third guide rails, the root sleeve 15 gradually moves outwards to push the corn on the root-opening drill bit 23 down.

[0021] The axes of the root-opening drill bit 23 and the root sleeve 15 are on the same straight line. A hole is opened at the central position of the root sleeve 15 for the root-opening drill bit 23 to penetrate into the root sleeve 15. Preferably, a smooth rod 13 is fixedly arranged on the bottom surface of the turntable 1, and a sliding sleeve 14 is slidably mounted on the smooth rod 13. The root sleeve 15 is fixedly arranged on the sliding sleeve 14, so that the root sleeve 15 can slide along the smooth rod 13. The root-opening drill bit 23 and the smooth rod 13 are both arranged along the radial direction of the turntable 1. The roller 19 is fixedly installed at the top position of the sliding sleeve 14 through a connecting rod. A long groove corresponding to the position of the smooth rod 13 is arranged on the turntable 1, and the connecting rod passes through the long groove so that the roller 19 is located above the turntable 1, facilitating the cooperation between the roller 19 and the guide rail.

[0022] A root-opening sleeve 21 is fixedly arranged on the bottom surface of the turntable 1. A root-opening rotating shaft 22 is arranged inside the root-opening sleeve 21. The root-opening drill bit 23 is fixedly installed at one end of the root-opening rotating shaft 22. A root-opening driving device is connected to the other end of the root-opening rotating shaft 22. When the root-opening drill bit 23 rotates, the root-opening action is realized. In the drawings of the present utility model, the root-opening sleeve 21 is fixed on the smooth rod 13, which is essentially the same as being fixed on the turntable 1, as long as the relative position with the turntable 1 can be kept unchanged.

[0023] A thrust mechanism is provided on the turntable 1 to push the sliding sleeve 14 outward. The thrust mechanism comprises a thrust sleeve 16 fixedly mounted on the top surface of the turntable 1 and a slide rod 17 sleeved within the thrust sleeve 16. One end of the slide rod 17 is fixedly connected to a connecting rod. A first spring 18 is provided on the slide rod 17, located between the thrust sleeve 16 and the connecting rod. The force of the first spring 18 keeps the roller 19 in close contact with the inner sides of the first and second guide rails.

[0024] The root opening drive device includes a drive motor 24, a drive sprocket connected to the drive motor 24, and a drive sprocket arranged at the other end of the root opening shaft 22. The drive motor 24 and the drive sprocket are driven by a chain, and the drive sprocket cooperates with the chain.

[0025] In the embodiment of the present invention, a fixing frame 9 may be further included, on which components that do not need to be moved, such as guide rails and drive motors 24, are mounted. The turntable 1 is also mounted at the center of the fixing frame 9 through a corresponding structure.

[0026] To enable automatic loading, a clamping device is also provided on the outside of the turntable 1. The clamping device includes a clamping frame 2, a clamping cylinder 3 mounted on the clamping frame 2, a clamping sleeve 10 fixed to the piston rod of the clamping cylinder 3, a clamping rod disposed within the clamping sleeve 10, a tip sleeve 11 fixedly mounted at the end of the clamping rod, and a third spring 12 disposed between the clamping sleeve 10 and the tip sleeve 11. The clamping cylinder 3 is mounted on the top surface of the clamping frame 2, and the clamping sleeve 10 is located below the clamping frame 2. The clamping frame 2 is also provided with a long slot, and the clamping sleeve 10 and the piston rod are connected together by a connecting rod disposed in the long slot. The movement direction of the piston rod of the clamping cylinder 3 is consistent with the radial direction of the turntable 1. When the fresh corn is located between the root sleeve 15 and the tip sleeve 11, the clamping cylinder 3 is actuated, and the tip sleeve 11 cooperates with one end of the corn to push the corn toward the side of the root sleeve 15, so that the other end of the corn cooperates with the root sleeve 15. The clamping cylinder 3 continues to move, driving the root sleeve 15 to move toward the root drill bit 23 until the root drill bit 23 passes through the root sleeve 15 and is inserted into the corn. After that, the root drill bit 23 rotates to cut the root of the corn, which is convenient for subsequent peeling processing.

[0027] When the utility model is in use, the root of the fresh corn is fitted with the root sleeve 15, and the root sleeve 15 is located near the root-opening drill bit 23. After the root-opening drill bit 23 passes through the root sleeve 15, it cooperates with the fresh corn. When the turntable 1 rotates, the root sleeve 15 and the root-opening drill bit 23 rotate together with the turntable 1. The roller 19 is in contact with the inner side of the first guide rail 6. When the roller 19 rotates with the turntable 1 to the positions of the second and third guide rails, the roller 19 enters the gap between the second and third guide rails. Under the guiding action of the guide rails, the root sleeve 15 gradually moves outwards, so as to pick the fresh corn off the root-opening drill bit 23 and realize automatic blanking.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
