Then, by starting the jacking assembly, the jacking assembly can pour the materials inside the feeding mechanism into the feeding port and conduct peeling through the peeling machine body, thereby achieving the effect of convenient feeding. This solves the problem that when the device is in processing, the user needs to manually lift the bucket for material filling, and it does not have an automatic feeding structure. Moreover, the peeling device is relatively high, and workers need to continuously use arm strength to lift the materials in the bucket and pour them into the peeling machine for peeling.

When feeding is required, there is no need to lift the bucket high for feeding. The materials are directly placed into the feeding hopper. Then, by starting the transmission mechanism, after the transmission mechanism drives the feeding mechanism to reach the designated position, the jacking assembly is started, enabling the jacking assembly to jack up the front end of the feeding hopper, causing the rear end of the feeding hopper movably installed with the limit frame to rise obliquely, so that the materials can generate an impact force to open the blanking door, and the materials fall into the feeding port through the opened blanking door for peeling, thereby achieving the effect of convenient feeding.

[0017] 3. The utility model fixes the jacking groove to the hydraulic cylinder by setting up a jacking component, then fixes the hydraulic cylinder to the jacking frame, and further fixes the jacking frame to the front end of the feeding hopper. When it is necessary to feed the materials inside the feeding hopper, the controller starts the hydraulic cylinder. The output end of the hydraulic cylinder drives the jacking frame to move upward, and the jacking frame drives the front end of the feeding hopper to move upward, making the feeding hopper tilt, so that the internal materials fall into the feeding port. Moreover, the telescopic rods can move synchronously along both sides of the jacking frame, playing an auxiliary moving role to prevent the jacking frame from tilting and ensuring the stability of jacking.

Then, the nut sleeve 105 is installed for transmission with the screw rod 101. When transmission is required, the controller 11 starts the servo motor 104, so that the output end of the servo motor 104 can drive the second helical gear 103 to rotate forward and backward, enabling the second helical gear 103 to drive the screw rod 101 to rotate forward and backward through the first helical gear 102, and enabling the screw rod 101 to drive the nut sleeve 105 to move up and down, thereby achieving the transmission effect.

When the material transportation is required after blanking, the above steps can be reversed to reset.

[0038] Working principle and usage process of the present utility model: When in use, when assembling the support frame 1, the peeling machine body 2, the feeding port 3, the discharging port 4 and the supporting legs 5, when automatic feeding through the feeding port 3 is required for peeling the peeling machine body 2, fix the feeding plate 801 to the slider 7, then fix the limiting frame 802 to the feeding plate 801, then movably install the inner side of the limiting frame 802 to the feeding hopper 803 through a movable shaft, and then slidably install the back surface of the feeding hopper 803 to the discharging door 804 through a pin. When feeding is required, there is no need to lift the bucket high for feeding. Just put the material into the feeding hopper 803. Movably install the screw rod 101 to the connecting plate 9, then fix the servo motor 104 to the second helical gear 103, then mesh the second helical gear 103 with the first helical gear 102 on the surface of the screw rod 101, and then drive and install the nut sleeve 105 to the screw rod 101. When transmission is required, start the servo motor 104 through the controller 11, so that the output end of the servo motor 104 can drive the second helical gear 103 to rotate forward, so that the second helical gear 103 can drive the screw rod 101 to rotate forward through the first helical gear 102, so that the screw rod 101 can drive the nut sleeve 105 to move upward, and then the nut sleeve 105 drives the feeding plate 801 to move through the slider 7. When moving to the specified position, rotate the rotating column 18, so that the rotating column 18 drives the limiting plate 17 to move to the limiting block 19, and magnetically connect the magnet 20 to the magnetic groove 21 to open the discharging door 804. Fix the jacking groove 8051 to the hydraulic cylinder 8052, fix the hydraulic cylinder 8052 to the jacking frame 8053, and then fix the jacking frame 8053 to the front end of the feeding hopper 803. When feeding the material inside the feeding hopper 803 is required, start the hydraulic cylinder 8052 through the controller 11, so that the output end of the hydraulic cylinder 8052 drives the jacking frame 8053 to move upward, so that the jacking frame 8053 drives the front end of the feeding hopper 803 to move upward, so that the feeding hopper 803 can be in an inclined state, so that the material can generate an impact force to open the discharging door 804, and the material falls into the feeding port 3 through the opened discharging door 804 for peeling. After feeding is completed, if feeding is required again, reverse the above steps to reset, thus achieving the effect of convenient feeding.

[0039] In summary, for the grain processing and peeling machine, by setting the controller 11, the controller 11 starts the transmission mechanism 10, enabling the transmission mechanism 10 to drive the feeding mechanism 8 to a specified position. Then, by starting the jacking component 805, the jacking component 805 can pour the materials inside the feeding mechanism 8 into the feeding port 3 for peeling by the peeling machine body 2, thereby achieving the effect of convenient feeding. This solves the problem that when the device is in processing, the user needs to manually lift the bucket to fill the materials, and it does not have an automatic feeding structure. Moreover, the peeling device is relatively high, and workers need to continuously use their arm strength to lift the materials in the bucket and pour them into the peeling machine for peeling. Over time, when the physical strength of the workers is greatly consumed, the feeding efficiency will be reduced, and thus the peeling efficiency will also be reduced, which has certain limitations.
