[0028] An L-shaped material dividing plate 9, the L-shaped material dividing plate 9 is slidably connected to the bottom of the mixing drum 1, and a material leakage groove 19 is opened on the surface of the L-shaped material dividing plate 9;

[0029] A driving mechanism is provided on one side of the L-shaped material dividing plate 9 , and the cylinder 7 of the driving mechanism drives the L-shaped material dividing plate 9 to move left and right inside the mixing drum 1 , so that the material leaks down through the leakage groove 19 .

[0030] The driving mechanism includes a polished rod 22 connected to one side of the mixing drum 1, the polished rod 22 passes through the L-shaped material dividing plate 9, the cylinder 7 is connected to the top of the fixed frame 10, and the surface of the polished rod 22 is sleeved with a spring 21 located on one side of the L-shaped material dividing plate 9.

[0031] The polished rod 22 passes through the L-shaped dividing plate 9 and is connected to the limiting plate 8 .

[0032] A sealing gasket 20 is connected to the surface of the L-shaped material dividing plate 9 inside the mixing drum 1 . The sealing gasket 20 can seal the material inside the mixing drum 1 .

[0033] A scraper 2 is connected to one side of the stirring rod 6, and one side of the scraper 2 is in contact with the inner wall of the mixing drum 1. The scraper 2 and the stirring rod 6 are integrally formed, and the scraper 2 can remove materials from the inner wall of the mixing drum 1. The bottom of the scraper 2 is in contact with the surface of the L-shaped dividing plate 9.

[0034] The output end of the first motor 11 is connected to a rotating rod 17, which extends to the inside of the fixed frame 10. A bearing is sleeved on the surface of the rotating rod 17, and the bearing is embedded in the inner wall of the fixed frame 10. The surface of the rotating rod 17 is connected to a spiral blade 16, and the spiral blade 16 and the rotating rod 17 are integrally formed. A discharge port 18 is connected to one side of the bottom of the fixed frame 10.

[0035] The surface of the base 15 is connected to a controller 13, which can control the operation of the first motor 11, the second motor 4 and the cylinder 7. The top of the base 15 is located at the bottom of the first motor 11 and is connected to a support block 12, which can support the first motor 11.

[0036] The bottom of the base 15 is connected with a universal wheel 14, which can drive the base 15 to move, thereby driving the base 15 to move to a specified position, and the universal wheel 14 has a brake function, which can be used to stop the movement of the universal wheel 14.

[0037] Specifically, when in use, after pouring the material into the mixing drum 1, the cover plate 3 with the second motor 4 is covered on the top of the mixing drum 1, and then the second motor 4 is started, so that the output end of the second motor 4 drives the rotating rod 5 and the stirring rod 6 to rotate together, so that the stirring rod 6 stirs the material inside the mixing drum 1, and the scraper 2 on one side of the stirring rod 6 will scrape the material on the inner wall of the mixing drum 1, so that the inner wall of the mixing drum 1 is always in a clean state, and then the scraper 2 and the stirring rod 6 are used together, so that the material inside the mixing drum 1 can be stirred;

After the L-shaped dividing plate 9 moves to a certain position, the leakage groove 19 on the surface of the L-shaped dividing plate 9 will enter the inside of the mixing drum 1, so that the material will move from the inside of the leakage groove 19 to the inside of the fixed frame 10, so that the material accumulated on the surface of the L-shaped dividing plate 9 will flow out from the inside of the leakage groove 19, and because the bottom of the scraper 2 is in contact with the surface of the L-shaped dividing plate 9, the material can be better separated from the surface of the L-shaped dividing plate 9.

[0039] After the material falls downward for a certain period of time, the controller 13 controls the output end of the cylinder 7 to drive the L-shaped material dividing plate 9 to move to the initial position, so that the leakage groove 19 on the surface of the L-shaped material dividing plate 9 is away from the inside of the mixing drum 1 (such as Figure 1 The state is shown), and the movement of the L-shaped dividing plate 9 can be limited by the setting of the light rod 22, so that the L-shaped dividing plate 9 is always in a horizontal state. The spring 21 on the surface of the light rod 22 can also be used to push the L-shaped dividing plate 9 to move, and the movement of the L-shaped dividing plate 9 driven by the cylinder 7 can be protected. Then, when the L-shaped dividing plate 9 is in reciprocating motion, the flow rate of the material inside the mixing drum 1 can be controlled, thereby preventing the subsequent materials from clogging the screw feeder;

[0040] Then, after the material enters the interior of the fixed frame 10, the output end of the first motor 11 is used to drive the rotating rod 17 and the spiral blade 16 to rotate, and the continuous rotation of the spiral blade 16 drives the material inside the fixed frame 10 to flow to one side of the discharge port 18, so that the material can flow downward from the inside of the discharge port 18 for collection.
