The two stirring frames 17 are connected to scrapers 16 on the separated sides through bolts 15. Two push rods 22 are fixedly connected to the bottom end of the outer periphery of the mixing shaft 12. By starting the motor 8 to drive the mixing shaft 12 to rotate, the stirring frame 17 on the mixing shaft 12 and the stirring rod inside it stir and mix the raw materials in the mixing chamber 1, thereby accelerating the mixing efficiency of the raw materials. When the stirring frame 17 stirs the raw materials, a scraper 16 is installed on the outer wall of the stirring frame 17 to clean the inner wall of the mixing chamber 1 to prevent the mixed raw materials from adhering to it and affecting the mixing of subsequent raw materials.
[0026] Reference Figure 2-Figure 3 Electric slide rails 11 are arranged on both sides of the upper end of the fixed frame 10, and a quantitative member 7 is slidably connected to one end of the two electric slide rails 11. The electric slide rails 11 are started to drive the quantitative member 7 to reciprocate inside the fixed frame 10, so that the quantitative member 7 moves to the feed hole on the fixed frame 10 and transports the raw materials inside to the mixing chamber 1 through the feed pipe 6. At the same time, the baffle at the rear end of the quantitative member 7 will block the feed hopper 9 to prevent the raw materials inside the feed hopper 9 from falling. When the quantitative member 7 moves back, the raw materials in the feed hopper 9 will enter the containing tube again, thereby realizing quantitative feeding of the device.
[0027] Reference Figure 4-Figure 6The right side of the mixing chamber 1 is connected with a replacement door 5 through a hinge, and a handle 4 is provided on the outer wall of the front end of the replacement door 5. The handle 4 is connected with a gear 21 through a connecting shaft, and the connecting shaft is rotatably connected to the inside of the replacement door 5. The outer periphery of the gear 21 is meshed and connected with a rack 20. The front end of the rack 20 is fixedly connected with a clamping piece 13, and the inside of the clamping piece 13 is connected with a clamping block 18 through two springs 19. By rotating the handle 4 on the outer wall of the mixing chamber 1, the gear 21 is driven to rotate on the rack 20 through the connecting shaft, so that the rack 20 drives the clamping piece 13 to move toward the inside of the replacement door 5. A connecting groove is provided at the connection between the clamping piece 13 and the mixing chamber 1. The clamping block 18 on the clamping piece 13 will be squeezed by the connecting groove, thereby being compressed into the clamping piece 13, so that the clamping piece 13 is separated from the mixing chamber 1, so that the replacement door 5 is opened to expose the scraper 16 inside the mixing chamber 1. A feeding hole is provided on the side away from the bottom end of the two fixed frames 10, and a feeding pipe 6 is fixedly connected inside the two feeding holes. The two feeding pipes 6 are fixedly connected to the outer wall of the mixing chamber 1 on the side close to each other. The raw materials transported by the quantitative member 7 enter the mixing chamber 1 through the feeding pipe 6. Four support columns 2 are fixedly connected to the bottom of the mixing chamber 1, and a discharge port 3 is fixedly connected to the middle end of the bottom of the mixing chamber 1. A control valve 14 is arranged inside the discharge port 3, which can be used to control the mixed raw materials in the discharge device. One end of the two springs 19 is connected to the bottom of the locking block 18, and the other ends of the two springs 19 are connected to the bottom of the inner wall of the locking member 13. A plurality of stirring rods are arranged inside the two stirring frames 17, and the other ends of the plurality of stirring rods are connected to the outer wall of the mixing shaft 12, so that when the raw materials are mixed, the raw materials are mixed more fully, so that the materials can be better processed later.
[0028] Working principle: the raw materials to be mixed are put into the feed hopper 9 above the device, and the raw materials inside the feed hopper 9 will enter the containing tube on the quantitative member 7. By starting the electric slide rail 11, the quantitative member 7 is driven to reciprocate inside the fixed frame 10, so that the quantitative member 7 moves to the feed hole on the fixed frame 10 and transports the internal raw materials to the mixing chamber 1 through the feed pipe 6. At the same time, the baffle at the rear end of the quantitative member 7 will block the feed hopper 9 to prevent the raw materials inside the feed hopper 9 from falling. When the quantitative member 7 moves back, the raw materials in the feed hopper 9 will enter the containing tube again, thereby realizing quantitative feeding of the device. The raw materials entering the mixing chamber 1 can be driven by the starting motor 8 to rotate the mixing shaft 12, so that the stirring frame 17 on the mixing shaft 12 and the stirring rod inside it stir and mix the raw materials in the mixing chamber 1, thereby accelerating the mixing efficiency of the raw materials. When the stirring frame 17 stirs the raw materials, a scraper 16 is installed on the outer wall of the stirring frame 17 to clean the inner wall of the mixing chamber 1 to prevent the mixed raw materials from adhering to the upper rear surface. The mixing of the raw materials will be affected. If the scraper 16 is used for cleaning the inner wall of the mixing chamber 1 for a long time, the scraper 16 will be damaged. The scraper 16 needs to be replaced. At this time, the handle 4 on the outer wall of the mixing chamber 1 can be rotated to drive the gear 21 to rotate on the rack 20 through the connecting shaft, so that the rack 20 drives the clamping member 13 to move inside the replacement door 5. A connecting groove is provided at the connection between the clamping member 13 and the mixing chamber 1. The clamping block 18 on the clamping member 13 will be squeezed by the connecting groove, thereby being compressed to the clamping member 13. The engaging member 13 is separated from the mixing chamber 1, so that the replacement door 5 is opened to expose the scraper 16 inside the mixing chamber 1, and the bolts 15 used to fix the stirring frame 17 and the scraper 16 are removed with a tool to replace the scraper 16. A control valve 14 is installed inside the discharge port 3 at the bottom of the mixing chamber 1 to control the discharge of the mixed raw materials in the device, and the push rod 22 can push the raw materials at the bottom of the mixing chamber 1 to make them fall into the discharge port 3 to prevent the raw materials from accumulating in the mixing chamber 1.
