It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] See also Figure 1-3The utility model provides a technical solution: comprising a device tube 1 with an open top and a negative pressure tube 14 arranged above the device tube 1.

[0021] A mounting hole is vertically penetrated at the bottom end of the inside of the device barrel 1, and a rotating seat 2 is vertically rotatably connected inside the mounting hole. A threaded rod 3 is vertically fixedly connected to the top of the rotating seat 2. A threaded sleeve 4 is threadedly connected to the outer surface of the threaded rod 3. A pushing plate 5 matching the inner diameter of the device barrel 1 is laterally fixedly connected to the outer surface of the threaded sleeve 4.

[0022] The top of the threaded rod 3 is fixedly connected to a connecting block 11, and a connecting ring 12 is laterally fixedly connected to a side surface of the connecting block 11. The bottom end of the negative pressure tube 14 is connected to a suction hose 13, and the bottom end of the suction hose 13 is rotatably connected to the inside of the connecting ring 12.

[0023] In this embodiment, when the device is in operation, the threaded rod 3 will continue to rotate. During the rotation, the threaded sleeve 4 on its surface will move along its length, thereby driving the pushing plate 5 on the outer surface of the threaded sleeve 4 to move upward, and the plastic particles inside the device tube 1 will be driven to lift upward, preventing the suction hose 13 from being too far away from the plastic particles and unable to suck up the particles. At the same time, the threaded rod 3 will also drive the connecting ring 12 to rotate during its rotation, and synchronously drive the plastic hose 13 to rotate, so that its absorption coverage area is improved, and there will be no residual residue, no waste, and the practicality of the device is improved.

[0024] Furthermore, a guide hole is vertically penetrated through the upper surface of the push plate 5 , and a guide column 6 is vertically slidably connected inside the guide hole, and the bottom end of the guide column 6 is fixedly connected to the bottom end inside the device tube 1 .

[0025] In this embodiment, the guide column 6 plays a guiding and limiting role, so that the push plate 5 and the threaded sleeve 4 of the device will not rotate synchronously with the rotation of the threaded rod 3.

[0026] Furthermore, the bottom end of the device tube 1 is fixedly connected to a device frame 8, the interior of the device frame 8 is fixedly connected to a motor 9, the output shaft surface of the motor 9 is fixedly connected to a driving gear 10, and the bottom end of the rotating seat 2 and the interior of the device frame 8 are fixedly connected to a driven gear 7 that meshes with the driving gear 10.

[0027] In this embodiment, when the motor 9 is running, its output shaft rotates, and the driving gear 10 on the surface of the output shaft drives the driven gear 7 to rotate, thereby driving the rotating seat 2 to rotate, thereby driving the threaded rod 3 to rotate.

[0028] Furthermore, a lap block 16 is fixedly connected to the outer surface of the connecting ring 12 , and a lap ring 18 matched with the lap block 16 is fixedly connected to the top end inside the device tube 1 .

[0029] In this embodiment, the overlapping blocks 16 and the overlapping rings 18 play the role of overlapping supports, and can support the connecting ring 12 to prevent the connecting ring 12 from tilting during the rotation process.

[0030] Furthermore, a mounting groove is formed at the bottom end of the lap block 16 , and a ball bearing 17 is disposed inside the mounting groove.

[0031] In this embodiment, the balls 17 ensure smooth movement of the lap block 16 on the lap ring 18 .

[0032] Furthermore, a plurality of supporting legs 15 are fixedly connected to the bottom end of the outer surface of the device tube 1 .

[0033] In this embodiment, the support legs 15 play a supporting role.

[0034] The working principle and use process of the utility model: After the utility model is installed, when the device is in operation, the threaded rod 3 will continue to rotate. During the rotation, the threaded sleeve 4 on its surface will move along its length direction, thereby driving the pushing plate 5 on the outer surface of the threaded sleeve 4 to move upward, and the plastic particles inside the device tube 1 will be driven to lift upward, preventing the suction hose 13 from being too far away from the plastic particles and unable to suck up the particles. At the same time, the threaded rod 3 will also drive the connecting ring 12 to rotate during its rotation, and synchronously drive the plastic hose 13 to rotate, so that its absorption coverage area is improved, and there will be no residual residue, no waste, and the practicality of the device is improved.
