A dustproof door 4 is provided at the top of the inner cavity of the feed shell 2. A feeding assembly 5 is provided below the dustproof door 4. A dust suction assembly 6 is provided on the left side of the feed shell 2. The dustproof door 4 includes two flip doors 401 located on the top sides of the inner cavity of the feed shell 2. The ends of the two flip doors 401 that are far apart from each other are rotatably connected to the left and right sides of the inner cavity of the feed shell 2, respectively. The feeding assembly 5 includes a diverting block 501 located in the inner cavity of the feed shell 2. The inner cavity of the feed housing 2 is symmetrically provided with guide plates 502 on both sides. Below the two guide plates 502, there is a feed plate 503. Both sides of the bottom of the feed plate 503 are rotatably connected to the connecting shaft 504. The bottom of the inner cavity of the feed housing 2 is provided with a dual-axis motor 505. Both ends of the dual-axis motor 505 are connected to lead screws 506. The ends of the two lead screws 506 away from the dual-axis motor 505 are respectively rotatably connected to the inner walls of the two sides of the feed housing 2. The surfaces of the two lead screws 506 are threaded with moving blocks 507. The dust collection assembly 6 includes a fan 601 provided on the left side of the feed housing 2. One side of the fan 601 is fixedly connected to the outer wall of the left side of the feed housing 2. The filter box 604 is provided below the fan 601.
[0025] like Figure 2 As shown, each of the two flip doors 401 has a telescopic spring 402 fixedly connected to one end of its bottom that is far from each other. The ends of the two telescopic springs 402 that are far from the flip doors 401 are fixedly connected to the inner walls of the left and right sides of the feed shell 2, respectively. Each of the two flip doors 401 has a telescopic rod 403 fixedly connected to the middle of its bottom. The ends of the two telescopic rods 403 that are far from the flip doors 401 are also rotatably connected to the inner walls of the two sides of the feed shell 2. The cross-section of the diverting block 501 is an isosceles triangle. The opposite sides of the two guide plates 502 are fixedly connected to the inner walls of the two sides of the feed shell 2, respectively. The tops of the two moving blocks 507 are rotatably connected to the ends of the two connecting shafts 504 that are far from the guide plates 502, respectively.
[0026] like Figure 2 , Figure 3 As shown, a suction pipe 602 is fixedly connected to the top of the blower 601. The end of the suction pipe 602 away from the blower 601 extends into the interior of the feed housing 2. The outer wall of the filter box 604 is fixedly connected to the left outer wall of the feed housing 2. A connecting pipe 603 is fixedly connected to the bottom of the blower 601.

[0027] The working process of this utility model is as follows: When in use, the container for adding raw materials pushes the two flip doors 401 downwards, causing the two telescopic springs 402 and the telescopic rod 403 to be compressed, contracted, and rotated. The raw materials fall onto the surface of the diverting block 501 and are diverted to both sides. The raw materials pass through the guide plates 502 on both sides and fall onto the top of the discharge plate 503, slowing down the speed and impact of the falling raw materials. At the same time, the dual-axis motor 505 drives the lead screws 506 on both sides to rotate, and the moving blocks 507 on the surface move closer to each other. The connecting shaft 504 is used to adjust the movement. The feeding plate 503 moves downward, and the raw material enters the interior of the mixer 1 through the bent feeding pipes 3 on both sides. The blower 601 uses the extraction pipe 602 and the connecting pipe 603 to extract the dust inside the feeding shell 2. The filter screen 606 filters the dust in the air. The dust falls into the dust collection box 605 for unified collection. After the feeding is completed, the flip door 401 flips back under the action of the telescopic spring 402 and the telescopic rod 403 to seal the feeding shell 2 and prevent fine dust from overflowing through the feeding shell 2 during the mixing process.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
