The outer side of the mounting frame 103 is also rotatably connected with a fixed frame 104. A feed box 109 is fixedly arranged on the upper surface of the bottom plate 101, and a return port 110 is opened on one side of the feed box 109, and the bottom end of the mounting frame 103 is located at the return port 110. In the embodiment, a material guide pipe 111 is connected to the outer wall of one side of the material delivery box 109, and a round bucket 112 is connected to the end of the material guide pipe 111. A support rod 113 is fixedly provided on the upper surface of the bottom plate 101, and a support seat 114 is fixedly provided on the top of the support rod 113. A material storage tank 115 is provided above the support seat 114. A support leg 117 is fixedly provided at the bottom end of the material storage tank 115, and a disc 118 is fixedly provided at the bottom end of the support leg 117. A moving wheel 119 is fixedly provided on the lower surface of the disc 118, and the round wheel 119 is fixedly provided on the lower surface of the disc 118. The disk 118 and the support seat 114 cooperate with each other and also include: a conveying mechanism, which is arranged in the conveying box 109 and is used to convey the material in the conveying box 109 to the hopper 108; a conducting mechanism, which is arranged in the discharge barrel 116 and is used to automatically release the blockage of the discharge barrel 116 when the discharge barrel 116 is docked with the round bucket 112, so that the material in the storage tank 115 is introduced into the round bucket 112 through the discharge barrel 116; a loading and unloading mechanism, which is arranged above the bottom plate 101 and is used for loading and unloading the storage tank 115.

[0017] The fixing frame 104 can be fixed to the feeding port of the sheath processing equipment, and then the storage tank 115 can be loaded onto the top of the round bucket 112 through the loading and unloading mechanism, so that the lower barrel 116 below the storage tank 115 is connected to the round bucket 112, and the support legs 117 at the bottom of the storage tank 115 are lifted by the support seat 114, and when the lower barrel 116 is connected to the round bucket 112, the blocking of the lower barrel 116 can be automatically released under the action of the conduction mechanism, so that the storage tank 115 The material in the feed box 109 is introduced into the round bucket 112 through the lower barrel 116, and then enters the feed box 109 along the guide pipe 111. At this time, the material in the feed box 109 can be introduced into the hopper 108 through the conveying mechanism. At the same time, the drive motor 105 can drive the shaft roller 106 to rotate, so that the conveyor belt 107 rotates together, and the hopper 108 can be transported to the feeding port of the sheath processing equipment. At the same time, the hopper 108 is turned over, so that the material in the hopper 108 is poured into the sheath processing equipment.

A servo motor 202 is fixedly arranged on the top of the lifting cylinder 201, and the output end of the servo motor 202 is rotatably connected to a rotating shaft 203. The rotating shaft 203 is rotatably arranged in the lifting cylinder 201, and the outer wall of the rotating shaft 203 is fixedly connected to an auger blade 204. The side wall of the lifting cylinder 201 is also connected to a discharge frame 205 aimed at the hopper 108. When the material in the feed box 109 needs to be introduced into the hopper 108, the servo motor 202 can be used to drive the rotating shaft 203 to rotate, and the rotating shaft 203 drives the auger blade 204 to rotate, so that the material at the bottom of the feed box 109 can be lifted into the lifting cylinder 201 and discharged into the hopper 108 through the discharge frame 205, which is very convenient to use.

[0019] As an embodiment of the present invention, please refer to Figure 6 The feed box 109 is fixedly provided with a guide plate 301 for guiding the materials falling back into the feed box 109 to the bottom end of the lifting cylinder 201.

The lower surface of the support leg 117 is connected to the lower surface of the support leg 117, and when the lower barrel 116 below the storage tank 115 is docked with the round bucket 112, the lower barrel 116 will first enter the round bucket 112. At this time, the top block 402 in the round bucket 112 will lift the telescopic rod 405, so that the first spring 406 is stretched. At this time, the sealing block 407 will move up together to release the blockage of the lower barrel 116, so that the material in the storage tank 115 is introduced into the round bucket 112 along the lower barrel 116, and as the storage tank 115 moves further downward, the disc 118 at the bottom of the supporting leg 117 will be stuck in the supporting seat 114, which plays a role in lifting the storage tank 115, so that the material in the storage tank 115 is stably introduced into the round bucket 112, which is very convenient to use.

[0022] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 8The loading and unloading mechanism includes a slide rail 501 fixedly arranged on the upper surface of the bottom plate 101, and a slider 502 is slidably arranged in the slide rail 501, a hydraulic cylinder 503 is fixedly arranged on the upper surface of the slider 502, and a support frame 504 is fixedly arranged at the telescopic end of the hydraulic cylinder 503, a side plate 507 is fixedly arranged on the side wall of the storage tank 115, and a block 508 is fixedly arranged on the lower surface of the side plate 507, and a support frame 504 is provided on the upper surface of the support frame 504.

The side wall of the bottom plate 101 is also provided with a limiting opening 509, and the disc 118 and the limiting opening 509 are matched. When the storage tank 115 needs to be loaded, the storage tank 115 can be directly pushed so that the disc 118 at the bottom of the storage tank 115 enters the limiting opening on one side of the bottom plate 101. 509, the position of the storage tank 115 can be quickly limited, and then the slider 502 in the slide rail 501 can be moved, so that the support frame 504 moves to the outside of the storage tank 115 and the block 508 is aligned with the slot 505, and then the support frame 504 can be raised by the hydraulic cylinder 503, so that the block 508 under the side plate 507 enters the slot 505, and the storage tank 115 can be raised by the support frame 504, and then the slider 502 is moved again until the slider 502 is blocked by the blocking rod 506. At this time, the discharge barrel 116 is just in a state of aligning with the circular bucket 112, and the support frame 504 is driven downward by the hydraulic cylinder 503 again. At this time, the discharge barrel 116 will dock with the circular bucket 112, and the disc 118 enters the support seat 114, so that the support seat 114 plays the role of supporting the storage tank 115, effectively realizing the rapid loading of the storage tank 115, and the use effect is better.
