The lower end of the discharge outlet 2 is provided with a rotating pipe 4 through a rotating joint 3. The outer wall of the rotating pipe 4 is connected to an inclined discharge pipe 5. The outer wall of the discharge pipe 5 is provided with a cleaning mechanism.

[0024] The cleaning mechanism includes a first mounting plate 6 fixedly connected to the upper end face of the discharge pipe 5, an electric push rod 7 mounted on the lower end face of the first mounting plate 6, the output end of the electric push rod 7 extending above the first mounting plate 6 and fixedly connected to a second mounting plate 8, a hexagonal shaft 9 rotatably connected to the lower end face of the second mounting plate 8, the lower end of the hexagonal shaft 9 extending into the interior of the discharge pipe 5 and fixedly connected to a brush roller 10.

[0025] In this embodiment: During discharge, the powder inside the tank 1 is discharged through the discharge port 2 into the discharge pipe 5 and discharged from the discharge pipe 5. The discharge pipe 5 can be rotated to facilitate adjustment of its direction as needed. When cleaning the discharge pipe 5, the electric push rod 7 is activated. The electric push rod 7 drives the second mounting plate 8 to move back and forth along the axial direction of the discharge pipe 5, which in turn drives the hexagonal shaft 9 to move back and forth. The hexagonal shaft 9 further drives the brush roller 10 to move back and forth on the inner wall of the discharge pipe 5 to clean the inner wall of the discharge pipe 5 and brush off the accumulated or clumped powder. No manual cleaning by the operator is required, and the effect is good.

[0026] As a technical optimization of this utility model, the cleaning mechanism further includes a sleeve 11 that penetrates and is rotatably connected to the outer wall of the first mounting plate 6. The hexagonal shaft 9 is slidably connected to the sleeve 11. A second pulley 20 is fixedly connected to the outer wall of the sleeve 11. A first drive motor 12 is installed on the lower end face of the first mounting plate 6. The output end of the first drive motor 12 extends to the top of the first mounting plate 6 and is fixedly connected to a first pulley 13. The first pulley 13 and the second pulley 20 are connected by belt drive.

[0027] In this embodiment: the first drive motor 12 is started, the first drive motor 12 drives the first pulley 13 to rotate, and then drives the second pulley 20 to rotate through the belt. The second pulley 20 further drives the sleeve 11 to rotate, and then drives the hexagonal shaft 9 to rotate. The hexagonal shaft 9 further drives the brush roller 10 to rotate, so that the brush roller 10 rotates while reciprocating on the inner wall of the discharge pipe 5, resulting in a good cleaning effect.

[0028] As a technical optimization of this utility model, a second drive motor 15 is installed on the upper end face of the tank body 1. The output end of the second drive motor 15 extends into the interior of the tank body 1 and is fixedly connected to a rotating shaft 16. The lower end of the rotating shaft 16 extends into the interior of the rotating tube 4 and is fixedly connected to a spiral blade 19.

[0029] In this embodiment: the second drive motor 15 is started, the second drive motor 15 drives the rotating shaft 16 to rotate, which in turn drives the spiral blade 19 to rotate, so that the powder in the tank 1 is discharged evenly.

[0030] As a technical optimization of this utility model, a plurality of stirring blades 18 are fixedly connected to the outer wall of the rotating shaft 16.

[0031] In this embodiment: when the rotating shaft 16 rotates, it drives multiple stirring blades 18 to rotate, stirring and mixing the powder in the tank 1.

[0032] As a technical optimization of this utility model, the outer wall of the rotating shaft 16 is fixedly connected to two scrapers 17 that abut against the inner wall of the tank body 1 via a connecting rod.

[0033] In this embodiment: when the rotating shaft 16 rotates, it drives the two scrapers 17 to rotate through the connecting rod, scraping the inner wall of the tank 1 to prevent the powder from adhering to the inner wall of the tank 1.

[0034] As a technical optimization of this utility model, both the inlet 14 and the outlet pipe 5 are threaded with sealing caps.

[0035] In this embodiment, sealing caps are threaded onto the outer walls of both the inlet 14 and the outlet pipe 5, making it easy to open or close the inlet 14 and the outlet pipe 5.

[0036] As a technical optimization of this utility model, a controller is provided on the outer wall of the tank body 1, and the electric push rod 7, the first drive motor 12 and the second drive motor 15 are all electrically connected to the controller.

[0037] In this embodiment, the controller facilitates the normal operation of the electric actuator 7, the first drive motor 12, and the second drive motor 15.

[0038] The working principle and usage process of this utility model are as follows: First, the powder to be mixed is introduced into the tank 1. Then, the second drive motor 15 is started, which drives the rotating shaft 16 to rotate, thereby driving multiple stirring blades 18 to rotate and mix the powder. When the rotating shaft 16 rotates, it drives two scrapers 17 to rotate via a connecting rod, scraping the inner wall of the tank 1 to prevent the powder from adhering to the inner wall. During discharge, the rotating shaft 16 drives the spiral blades 19 to rotate, causing the powder inside the tank 1 to be discharged through the discharge port 2 into the discharge pipe 5. The sealing cover on the outer wall of the discharge pipe 5 is opened, allowing the powder to be discharged from the discharge pipe 5. The discharge pipe 5 can be rotated, facilitating adjustment of its direction and cleaning as needed. At 5 o'clock, the electric actuator 7 is started. The electric actuator 7 drives the second mounting plate 8 to move back and forth along the axial direction of the discharge pipe 5, which in turn drives the hexagonal shaft 9 to move back and forth. The hexagonal shaft 9 further drives the brush roller 10 to move back and forth on the inner wall of the discharge pipe 5. At the same time, the first drive motor 12 is started. The first drive motor 12 drives the first pulley 13 to rotate, which in turn drives the second pulley 20 to rotate via the belt. The second pulley 20 further drives the sleeve 11 to rotate, which in turn drives the hexagonal shaft 9 to rotate. The hexagonal shaft 9 further drives the brush roller 10 to rotate, so that the brush roller 10 rotates while moving back and forth on the inner wall of the discharge pipe 5, cleaning the inner wall of the discharge pipe 5 and brushing off the accumulated or clumped powder. No manual cleaning by the operator is required, and the effect is good.
