[0024] The metering component 13 includes a box body 1301 movably installed at the bottom of the support frame 5. Installation grooves 1302 are provided in the middle of both sides of the box body 1301. Adjusting frames 1303 are installed on both sides of the installation grooves 1302. A baffle 1304 is slidably connected inside the adjusting frame 1303. One end of the baffle 1304 is slidably connected to a slide bar 1305. The other end of the baffle 1304 is threadedly connected to a screw rod 1306. A third driving motor 1307 is installed on one side of the screw rod 1306.

[0025] The cleaning component 14 includes side plates 1401 movably installed on both sides of the machine body 1. A second driving motor 1402 is installed on one side of the side plate 1401. A rotating shaft 1403 is driven on one side of the second driving motor 1402. A second tool holder 1404 is installed on the surface of the rotating shaft 1403. A number of sleeves 1405 are installed on both sides of the rotating shaft 1403. One side of the inner wall of the sleeve 1405 is installed with a buffer spring 1406. A connecting shaft 1407 is installed on one side of the buffer spring 1406. A cleaning frame 1408 is installed on one side of the connecting shaft 1407.

[0026] In this embodiment, as Figure 1 shown, the bottom columns 2 are symmetrically distributed with respect to the horizontal center line of the machine body 1; the symmetrical distribution layout can balance the load of the machine body 1, reduce the stress concentration of the structure, improve the overall compressive capacity and durability, and at the same time helps to optimize the design to ensure that the machine body 1 is more reliable and safe during operation.

[0027] In this embodiment, as Figure 3 shown, the baffle 1304 and the third driving motor 1307 constitute a transmission structure through the screw rod 1306; the design of the transmission structure can automatically and flexibly control the opening and closing of the baffle 1304 through the action of the third driving motor 1307, and at the same time can control the feeding speed by adjusting the opening amplitude, thereby realizing the function of metering feeding, simplifying the operation process, and improving the metering efficiency and accuracy.

[0028] In this embodiment, as Figure 2 shown, the first tool holder 11 and the first driving motor 8 constitute a rotating structure through the stirring shaft 10; the design of the rotating structure can drive the stirring shaft 10 to rotate through the first driving motor 8, and then drive the first tool holder 11 to rotate for stirring and crushing work, which is beneficial to the full mixing of different raw materials, improves the mixing quality and mixing efficiency, and the stirring work avoids the problem of easy accumulation and blockage of raw materials.

[0029] In this embodiment, as Figure 3As shown, the baffle 1304 and the adjustment frame 1303 form a sliding structure; the design of the sliding structure ensures that the baffle 1304 can be flexibly and smoothly displaced along the direction of the adjustment frame 1303, ensuring that the baffle 1304 can be flexibly opened and closed during mixing work without getting stuck, thereby improving the smoothness of metering and feeding and improving operating efficiency.

[0031] In this embodiment, Figure 2 As shown, the first blade holder 11 is evenly and equidistantly distributed on the surface of the stirring shaft 10; the equidistant distribution layout design ensures that the raw materials are evenly stressed and mixed during the entire stirring process, effectively improving the stirring efficiency and mixing quality. Through the uniform and comprehensive action, it can ensure that the raw materials to be mixed are fully broken up and not prone to blockage, thereby ensuring the consistency and quality stability of the product during the production process.

[0032] The use method and advantages of the utility model: When the mixer with the feed metering structure is used, the working process is as follows:

[0033] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, first, the operator injects the required production raw materials into the feed covers 9 at the tops of the two end storage bins respectively. Under the guiding action of the feed covers 9, the production raw materials enter the interior of the storage bin body 6. Then, the first driving motor 8 is started to drive the stirring shaft 10 to rotate, so that the first tool rest 11 can uniformly and fully stir and disperse the production raw materials, which is beneficial to accelerating the mixing between different raw materials and avoiding the accumulation and blockage of the raw materials at the feed inlet. Then, the stirred raw materials fall on the surface of the baffle 1304. At this time, the third driving motor 1307 is started to conveniently drive the opening and closing of the baffle 1304, and at the same time, the feeding speed of the raw materials can be controlled by adjusting the opening and closing amplitude of the baffle 1304, thus realizing the function of metering feeding. Further, different types of raw materials fall into the interior of the machine body 1 through the feed inlet at the same time. At this time, the second driving motor 1402 is started to drive the second tool rest 1404 and the cleaning roller 1409 to rotate for the raw material mixing work. The cleaning roller 1409 can ensure that the mixed raw materials are not accumulated and adhered to the inner wall of the machine body 1, which is helpful for subsequent cleaning and improving the quality of raw material mixing. After the raw material mixing production is completed, it can be discharged through the discharge port 4 at the bottom of the machine body 1. Finally, clean water can be injected into the interior of the machine body 1, and the inner wall of the machine body 1 can be cleaned by using the cleaning roller 1409 in the same way. The sewage after cleaning can be directly discharged from the discharge port 4.
