[0030] See also Figure 1-5 The utility model provides a technical solution: a quantitative feeding device for raw materials in a mixing warehouse, comprising a mixing warehouse body 1, a feeding device, which is arranged at the lower end of the mixing warehouse body 1, and a mixing component, which is arranged inside the mixing warehouse body 1, and the mixing component comprises a first driving motor 5, and the output end of the first driving motor 5 is fixedly connected to a first rotating shaft 6, the first rotating shaft 6 is rotatably connected to the mixing warehouse body 1, the surface of the first rotating shaft 6 is fixedly connected to a first spiral stirring blade 7, the surface of the first rotating shaft 6 is fixedly connected to a stirring rod 8, and the surface of the first rotating shaft 6 is fixedly connected to a stirring plate 9.

[0031] The mixing assembly also includes a stirring blade connecting rod 10, which is fixedly connected to the lower end of the first rotating shaft 6. The lower end of the stirring blade connecting rod 10 is fixedly connected to a second spiral stirring blade 11. The second spiral stirring blade 11 is in the shape of a spiral that is small at the bottom and large at the top. A plurality of second through holes 13 are evenly arranged on the surface of the second spiral stirring blade 11.

[0032] There are two first spiral stirring blades 7 and four stirring rods 8, all of which are fixedly connected to the surface of the first rotating shaft 6. A plurality of first through holes 12 are evenly arranged on the surfaces of the two first spiral stirring blades 7. The two first spiral stirring blades 7 are in a spiral shape that is larger at the bottom and smaller at the top.

[0033] The unloading component includes a mixing warehouse discharge pipe 2, which is fixedly connected to the lower end of the mixing warehouse body 1, and a valve is installed inside the mixing warehouse discharge pipe 2. The lower end of the mixing warehouse discharge pipe 2 is fixedly connected to a raw material conveying pipe 3, and the left end of the raw material conveying pipe 3 is fixedly connected to a second driving motor 17, and the output end of the second driving motor 17 is fixedly connected to a second rotating shaft 18, and the second rotating shaft 18 is rotatably connected to the inside of the raw material conveying pipe 3, and the surface of the second rotating shaft 18 is fixedly connected to a spiral conveying blade 19.

[0034] A scraper frame 14 is fixedly connected to the surface of the first rotating shaft 6, and two scraper connecting rods 16 are fixedly connected to the inside of the scraper frame 14. The two scraper connecting rods 16 are fixedly connected to the cement raw material scraper 15 at one end close to the preparation warehouse body 1, and the cement raw material scraper 15 is in contact with the inner wall of the preparation warehouse body 1. There are two scraper frames 14 and two cement raw material scrapers 15, and there are four scraper connecting rods 16, which are symmetrically arranged on the surface of the first rotating shaft 6.

[0036] During the process of mixing and stirring the cement raw materials, the cement raw materials will be squeezed. The first through hole 12 and the second through hole 13 can reduce the squeezing of the cement, making it easier for the first spiral stirring blade 7 and the second spiral stirring blade 11 to fully contact the cement raw materials. Due to the special shapes of the first spiral stirring blade 7 and the second spiral stirring blade 11, it is easy to break up the cement raw materials, and the cement raw materials can flow from the inner side and edge of the second spiral stirring blade 11. During the rotation of the second spiral stirring blade 11, it is easy to control the feeding rate of the cement raw materials to prevent the cement raw materials from agglomerating under the action of squeezing and clogging the discharge pipe 2 of the mixing warehouse.

[0037] The first rotating shaft 6 drives the scraper frame 14 to rotate, and the scraper frame 14 drives the cement raw material scraper 15 and the scraper connecting rod 16 to rotate.

When the cement raw materials are mixed evenly, the valve is opened to discharge the cement raw materials from the mixing warehouse discharge pipe 2 to the inside of the raw material delivery pipe 3.

[0038] The second driving motor 17 is started to drive the second rotating shaft 18 and the spiral conveying blade 19 to convey the cement raw material, so as to facilitate the quantitative feeding of the cement raw material. The second spiral stirring blade 11 cooperates with the bottom of the batching warehouse body 1 to facilitate the adjustment of the feeding speed of the cement raw material and prevent the batching warehouse body 1 from being blocked by excessive cement raw materials.

[0039] Furthermore, the cement raw material is stirred by the first spiral stirring blade 7 and the second spiral stirring blade 11.

[0042] During the process of mixing and stirring the cement raw materials, the cement raw materials will be squeezed. The first through hole 12 and the second through hole 13 can reduce the squeezing of the cement, making it easier for the first spiral stirring blade 7 and the second spiral stirring blade 11 to fully contact the cement raw materials. Due to the special shapes of the first spiral stirring blade 7 and the second spiral stirring blade 11, it is easy to break up the cement raw materials, and the cement raw materials can flow from the inner side and edge of the second spiral stirring blade 11. During the rotation of the second spiral stirring blade 11, it is easy to control the feeding rate of the cement raw materials to prevent the cement raw materials from agglomerating under the action of squeezing and clogging the discharge pipe 2 of the mixing warehouse.

[0043] The first rotating shaft 6 drives the scraper frame 14 to rotate, and the scraper frame 14 drives the cement raw material scraper 15 and the scraper connecting rod 16 to rotate. The cement raw material scraper 15 scrapes the inner wall of the mixing warehouse body 1 to prevent the cement raw material from adhering to the inner wall of the mixing warehouse body 1. When the cement raw materials are mixed evenly, the valve is opened to discharge the cement raw materials from the mixing warehouse discharge pipe 2 to the inside of the raw material delivery pipe 3.

[0044] The second driving motor 17 is started to drive the second rotating shaft 18 and the spiral conveying blade 19 to convey the cement raw material, so as to facilitate the quantitative feeding of the cement raw material.
