A discharge pipe is fixedly connected to the screw feeder, and a docking ring is fixedly connected to the outer surface of the discharge pipe. Two positioning grooves are provided on the docking ring. A connecting ring is fixedly connected to the hopper, and two positioning blocks are fixedly connected to the lower surface of the connecting ring. Each of the two positioning blocks has two connecting grooves.

[0006] Two guide rods are fixedly connected to the inner surface of the docking ring. Two sliders are slidably connected to the outer surfaces of the two guide rods. A docking block is fixedly connected to each of the four sliders. A limit groove is formed on each of the four docking blocks.

[0030] Reference Figure 1-8This utility model discloses a portable feeding device, which includes a screw feeder 1 and a hopper 2. A feeding pipe 3 is fixedly connected to the screw feeder 1, and a docking ring 4 is fixedly connected to the outer surface of the feeding pipe 3. Two positioning grooves 5 are provided on the docking ring 4. A connecting ring 7 is fixedly connected to the hopper 2. The lower surface of the connecting ring 7 is in contact with the docking ring 4. Two positioning blocks 6 are fixedly connected to the lower surface of the connecting ring 7. The outer surface of the positioning blocks 6 is movably connected to the positioning grooves 5. Two connecting grooves 18 are provided on each of the two positioning blocks 6. Two handles 8 are fixedly connected to the side surface of the hopper 2. The number of handles 8 is two and they are symmetrically distributed. The handles 8 facilitate the operation of the hopper 2.

[0031] Two guide rods 9 are fixedly connected to the inner surface of the docking ring 4. Two sliders 10 are slidably connected to the outer surfaces of the two guide rods 9. The guide rods 9 pass through the sliders 10. Under the action of the guide rods 9, the stability of the sliders 10 during movement can be improved. A docking block 11 is fixedly connected to each of the four sliders 10. The outer surface of the docking block 11 is movably connected to the connecting groove 18. Limiting grooves 12 are provided on each of the four docking blocks 11. Four limiting blocks 13 are slidably connected to the inner surface of the connecting ring 7. Sliding rods 14 are fixedly connected to the side surfaces of the four limiting blocks 13. The outer surface of the sliding rods 14 is slidably connected to the connecting ring 7. The same connecting rod is fixedly connected to each of the corresponding two sliding rods 14. The lower surfaces of the two connecting rods 15 are fixedly connected to two fixing blocks 16. The outer surface of the fixing blocks 16 is movably connected to the limiting groove 12. The outer surface of the sliding rod 14 is slidably sleeved with a spring 17. One end of the spring 17 is fixedly connected to the side surface of the limiting block 13, and the end of the spring 17 away from the limiting block 13 is fixedly connected to the inner side wall of the connecting ring 7. Under the action of the spring 17, the fixing block 16 can quickly enter the limiting groove 12. The connecting ring 4 is provided with a first sliding groove 19, and the outer surface of the slider 10 is slidably connected to the first sliding groove 19. The connecting ring 7 is provided with a second sliding groove 20, and the outer surface of the limiting block 13 is slidably connected to the second sliding groove 20.

[0032] Working principle: By pulling the connecting rod 15, the moving connecting rod 15 can drive the fixed block 16, the sliding rod 14, and the limiting block 13 to move. During the movement, the limiting block 13 gradually compresses the spring 17, thus keeping the spring 17 taut. When the moving fixed block 16 disengages from the limiting groove 12, it releases the fixing of the mating block 11. Then, pulling the two mating blocks 11 separately causes the moving mating blocks 11 to drive the limiting groove 12 and the slider 10 to move. When the moving limiting groove 12... After aligning with the fixing block 16, release the connecting rod 15, causing the spring 17 to rebound and be released from pressure. The rebounding spring 17 then drives the limiting block 13, sliding rod 14, connecting rod 15, and fixing block 16 to move back to their original positions. Repeat the above operation on the other side to release the fixing of the hopper 2. Then lift the handle 8 upwards to remove the handle 8 and its structure from the screw feeder 1, completing the disassembly of the screw feeder 1 and the hopper 2, thereby reducing the space occupied by the screw feeder 1. In addition to reducing the weight of the screw feeder 1, the portability of the screw feeder 1 can be improved. When installing the screw feeder 1 and the hopper 2, the positioning block 6 is inserted into the positioning groove 5 on the docking ring 4, and then the connecting rod 15 is pulled. The moving connecting rod 15 drives the limiting block 13, the sliding rod 14 and the fixed block 16 to move, while keeping the spring 17 in a taut state. When the moving fixed block 16 does not affect the connection between the docking block 11 and the connecting groove 18, the two docking blocks 11 are pushed respectively, so that the docking blocks 11... The limiting groove 12 and the slider 10 move in opposite directions. When the moving docking block 11 is inserted into the connecting groove 18, the moving limiting groove 12 can correspond to the fixed block 16. Then the connecting rod 15 is released, so that the spring 17 is no longer compressed and rebounds. The rebounding spring 17 can drive the limiting block 13, the slider 14, the connecting rod 15 and the fixed block 16 to move back to their original positions. When the moving fixed block 16 enters the limiting groove 12, the above operation is repeated to complete the connection and fixation between the screw feeder 1 and the hopper 2.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
