[0034] The discharge assembly 6 includes a collection bin 61 welded to the bottom discharge port of the L-shaped discharge pipe 5, a discharge pipeline 62 is rotatably installed at the discharge end of the collection bin 61, and a cover plate 63 is rotatably provided at the vertical pipe end of the discharge pipeline 62. At the same time, the cover plate 63 is used to be installed at the upper end of the feed port of the mixing cylinder to seal the feed port to prevent external impurities from entering the interior of the mixing cylinder from the open inlet.

[0035] A through hole is formed at the center of the top of the cover plate 63 , a bearing is installed inside the through hole, and the cover plate 63 is rotatably connected to the vertical pipe end of the discharge pipeline 62 through the bearing.

[0036] The discharge pipeline 62 includes a vertical feed pipe 621 rotatably installed at the outlet end of the collecting bin 61 through a bearing. A shaping hose 622 is installed at the outlet end of the vertical feed pipe 621. The shaping hose 622 is made of silicone material. An inclined discharge pipe 623 is installed at the outlet end of the shaping hose 622. The inclined pipe is used to change the outlet direction of the material.

[0037] A driving motor 65 is installed on one side of the top of the cover plate 63. A gear 66 is sleeved on the driving end of the driving motor 65 and the upper side of the outer wall of the vertical feed pipe 621, and the two gears 66 are meshed. When the material passes through the inside of the discharge pipe 62, the driving motor 65 drives the gear 66 thereon to rotate. Under the transmission action of the two meshing gears 66, the discharge pipe 62 is rotated. When the discharge pipe 62 rotates, the outlet of the discharge pipe 62, that is, the outlet position of the inclined discharge pipe 623, will change in direction accordingly, so that the direction of the material discharged through the inclined discharge pipe 623 will change, which can expand the area where the material enters the mixing cylinder.

The material will continuously enter the discharge pipeline 62 through the guidance of the collecting bin 61, and finally fall into the mixing bin.

[0041] Example 2

[0042] Reference Figure 1-4 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0043] A magnet bar 624 is fixedly mounted on the outer wall of the inclined discharge pipe 623 , and a circle of magnetic structure 64 is mounted on the outward edge of the bottom of the cover plate 63 .

[0044] The magnetic structure 64 includes a mounting seat 641 mounted on the bottom of the cover plate 63 . A T-shaped slot 644 is formed on the outside of the mounting seat 641 . A T-shaped block 646 is clamped inside the T-shaped slot 644 . An electromagnet 645 is installed at the bottom of the T-shaped block 646 .

[0045] A blocking plate 642 is provided on the outer side of the mounting seat 641, and threaded holes are provided on the outer sides of the mounting seat 641 and the blocking plate 642, and screws 643 are threadedly installed between the two threaded holes on the blocking plate 642 and the mounting seat 641. The blocking plate 642 is installed on the side of the mounting seat 641 by the screws 643, which facilitates the installation and disassembly of the electromagnet 645.

[0046] Two electromagnets 645 are connected, one is in an attractive state with the magnet bar 624, and the other is in an attractive state with the magnet bar 624, and the magnetism of the electromagnets 645 that repel or attract the magnet bar 624 is different. Under the state of magnetic attraction and repulsion between different electromagnets 645 and the magnet bar 624, the inclined discharge pipe 623 is constantly in a state of "nodding" up and down, and the area where the material falls into the mixing cylinder is progressively changed at this time, which is more conducive to the uniform dispersion of the material inside the mixing cylinder. The bending of the shaping hose 622 can also be adjusted through a certain inclined discharge pipe 623 to change the outlet position of the inclined discharge pipe 623. The outlet position of the inclined discharge pipe 623 is only adjusted once and then rotated for users to choose.

[0047] During use, when the oblique discharge tube 623 rotates, the electromagnet 645 is turned on, and the oblique discharge tube 623 is constantly in a state of "nodding" up and down under the state of magnetic attraction and repulsion between different electromagnets 645 and magnet bars 624, thereby further changing the area where the material falls into the mixing cylinder.
