[0033] The specific embodiments of the present invention 1-10 are further described in detail below with reference to the accompanying drawings.

[0034] When this embodiment is in use, the main body of the peeling machine is a support frame 1, the upper end face of the support frame 1 is arranged obliquely, and the obliquely upward protruding end of the upper end face of the support frame 1 is the feeding part and the obliquely downward protruding end is the discharging part. The feeding part is provided with a plurality of feeding partition plates 7 and the discharging part is provided with a discharge guide plate 8. Blocking guard plates 2 for preventing corn from falling are respectively provided at both ends of the support frame 1, and a plurality of obliquely arranged and parallel peeling components are provided between the feeding part and the discharging part. Each peeling component is composed of four peeling rollers arranged parallel to each other, and the peeling rollers of each group are, from left to right, the first peeling roller and the second peeling roller. Roller 3, second peeling roller 4, third peeling roller 5 and fourth peeling roller 6, wherein the first peeling roller 3 and the second peeling roller 4 are located on the left, and the third peeling roller 5 and the fourth peeling roller 6 are located on the right, and the first peeling roller 3 and the second peeling roller 4 are connected at both ends by gear transmission, so that the rotation directions of the two peeling rollers are opposite, and the third peeling roller 5 and the fourth peeling roller 6 are also connected at both ends by gear transmission, so that the rotation directions of the two peeling rollers are opposite, the second peeling roller 4 and the third peeling roller 5 are located in the middle and higher than the first peeling roller 3 and the fourth peeling roller 6, the first peeling roller 3 ... The four peeling rollers 6 have the same height, and the second peeling roller 4 and the third peeling roller 5 have the same height. In this way, after the corn enters the upper end surface of the support frame 1 from the feeding part at the upper end of the support frame 1, the corn will be transported under the conveying of the obliquely arranged peeling components and the gravity generated by the oblique arrangement. Since the heights of the second peeling roller 4 and the third peeling roller 5 are higher than the first peeling roller 3 and the fourth peeling roller 6, and the first peeling roller 3 and the third peeling roller 5 rotate clockwise, and the second peeling roller 4 and the fourth peeling roller 6 rotate counterclockwise, the corn will be transported in the rotating peeling roller when entering each group of peeling components. Under the action of the skin rollers, it moves toward both ends. At the same time, the first peeling roller 3 and the second peeling roller 4 will produce a winding effect on the outer surface of the corn during the rotation, so that the corn husks will be continuously wound in after being wound into between the two peeling rollers until they touch the corn body. Only then will the root of the husks be disconnected from the corn cob under the winding action, thereby realizing the peeling action. During the peeling process, the corn will be transported synchronously, so that the peeled corn will be discharged from the discharge position, and the peeled husks will fall into the funnel-shaped debris outlet 9 below the peeling component and be discharged.

[0035] During the peeling process, a spirally arranged anti-slip layer is provided on each peeling roller to prevent the husks from falling off during the peeling process, and a covering safety shield is provided at the upper end of the support frame 1. The safety shield is used to prevent the corn from jumping during the peeling process. The support leg at the lower end of the support frame 1 is rotatably connected to the base at one end close to the feeding part, and an angle adjustment bolt is screwed on the end close to the discharge part. The inclination angle of the upper end face of the support frame 1 is adjusted by adjusting the extended length of the angle adjustment bolt, and a spirally arranged discharge guide pattern is provided at the end of the first peeling roller 3 and the fourth peeling roller 6 close to the discharge guide plate 8. The discharge guide pattern is used to prevent the corn from being stuck at the end of the peeling roller due to lack of driving force.

[0036] At the lower end of the funnel-shaped debris outlet 9, a debris conveying mechanism for processing the peeled husks, fallen corn kernels and residues is fixedly connected. When the husks fall downward from the debris outlet 9 onto the debris conveying mechanism, the husks and debris will first fall onto the screen 11 located at the upper end of the debris conveying frame 10. Since the screen 11 is arranged obliquely and in an array, the gaps in the screen 11 are smaller than the distance the husks pass through, so that the husks will not fall downward. When the husks on the screen 11 are on the obliquely arranged screen 11, they will be guided by the oblique guiding effect and the vibration of the entire equipment. It moves along the screen 11, so that when the debris passes through the screen 11, the bracts larger than the gaps of the screen 11 will fall at the end of the screen 11 under the guidance of the oblique screen 11, while the debris smaller than the gaps of the screen 11 will fall from the screen 11 to the bottom of the screen 11. Below the screen 11 is a first filter cavity 12, and a first conveyor belt 13 is provided at the lower end of the first filter cavity 12. At the obliquely downward extending end of the screen 11 is a leaf outlet cavity 14, and a second conveyor belt 15 for conveying the bracts is provided at the lower end of the leaf outlet cavity 14. At this time, the preliminary separation according to volume is completed.

[0037] A limiting net 16 is provided on the side of the blade outlet cavity 14 away from the screen 11 to prevent the bracts from passing through, and a downward connecting port is provided on the outside of the limiting net 16. A filtering device for filtering debris is provided below the first conveyor belt 13 and the second conveyor belt 15, and air circulation is required when the filtering device is in operation. The air inlet of the air circulation is the connecting port on the outside of the limiting net 16, and the air outlet of the air circulation is the right end of the filter housing 17 corresponding to the right end of the screen 11, so that the air completes a counterclockwise air circulation in the debris conveying rack 10, and during the air circulation process, the debris in the air is filtered through the filter sheet 18 in the filter housing 17.

[0038] The debris filtering device includes a filter housing 17, which is divided into two parts, the lower end of the filter housing 17 is a transverse through-channel, and the upper end of the filter housing 17 is provided with a plurality of vertically arranged and evenly spaced storage slots, each storage slot is vertically slidably connected to a filter plate 18, and each filter plate 18 is fixedly connected to a drive rod 19 at both ends and extends out of the filter housing 17, and a vertically arranged check tooth is fixedly connected at the corresponding positions of the filter plates 18 at both ends of the filter housing 17. The drive rods 19 are fixedly connected to a check piece 25 that matches the check rack 26. Each check piece 25 extends obliquely downward and is stuck on the check rack 26 to prevent the drive rod 19 from moving downward without external force. A paddle 27 extending obliquely outward is fixedly connected to the outside of each check piece 25. The check piece 25 is driven by driving the paddle 27, so that when the paddle 27 is pressed, the check piece 25 is driven to move and disengage from the check rack 26. The lifting rod 21 is provided at the outer side of the filter housing 17 at the position corresponding to the driving rod 19. The lifting rod 21 is horizontally arranged and the lower end of the lifting rod 21 is supported by an electric telescopic rod 22. The height of the lifting rod 21 can be adjusted by adjusting the height of the electric telescopic rod 22. A connecting rod 23 is slidably connected inside the lifting rod 21. The middle part of the connecting rod 23 cooperates with the lifting rod 21 through a threaded connection, so that when the threaded rod in the lifting rod 21 rotates, the connecting rod 23 is driven to slide horizontally along the lifting rod 21 through threaded transmission. Telescopic connecting members 24 are fixedly connected at both ends of the connecting rod 23, and the telescopic connecting members 24 are respectively extended toward the driving rod 19. A sleeve for connecting the extended end of the driving rod 19 is fixedly connected to the extended end of the telescopic connecting member 24. At the same time, a pressing piece 28 for toggling the paddle 27 is fixedly connected to the extended end of the telescopic connecting member 24, so that when the telescopic connecting member 24 is connected to the driving rod 19, the pressing piece 28 will synchronously press the paddle 27.

[0039] The movement principle in the process of driving the driving rod 19 through the telescopic connection 24 is that in the initial state, all the filter plates 18 are in the corresponding storage grooves and the corresponding driving rods 19 are respectively located at the upper ends, and the check plates 25 fixedly connected to each driving rod 19 are extended obliquely downward and cooperate with the check racks 26, so they are positioned to prevent downward movement. The telescopic connection 24 moves upward under the action of the lifting rod 21 until the telescopic connection 24 moves upward to the position corresponding to the driving rod 19 and stops moving. Then the telescopic connection 24 is extended. The extended end of the telescopic connection 24 will be sleeved on the extended end of the driving rod 19 when it is extended, so that the driving rod 19 will then rise and fall with the lifting rod 21, and the pressing piece fixed on the extended end of the telescopic connection 24 28 will press the paddle 27, causing the check plate 25 to move and disengage from the check rack 26. At this time, the lifting rod 21 can drive the driving rod 19 to lift when it is lifted, so that the corresponding filter 18 moves downward and blocks the filter channel. At this time, the air passing through the filter channel will be filtered by the filter net until it needs to be replaced. The used filter 18 will be moved upward first, and then the telescopic connection 24 will be reset. At this time, the check plate 25 will lose the pressure and will be reset to prevent it from falling downward. Then the connecting rod 23 will be driven to move a certain distance in the lifting rod 21, so that the telescopic connection 24 corresponds to the position of the next group of filters 18, and then the above steps are repeated for replacement. In order to achieve better filtering effect, the filter arrangement for each downward movement is greater than or equal to two.

[0040] An exhaust fan 20 is fixedly connected to the right end of the filter housing 17, and the exhaust fan 20 is used to exhaust the filter channel, so that the air moves from the left end of the filter channel to the right, and the air outlet of the exhaust fan 20 is the right end of the first filter cavity 12, so that the air circulates counterclockwise in the debris conveying rack 10 and is continuously filtered through the filter screen during the circulation process.
