[0029] By setting up the stirring structure 6 and starting the motor 62, the stirring rod 63 is driven to rotate under the action of the transmission component 61, and then the stirring blade 64 is driven to rotate, so that the raw material components are fully mixed and reacted, thereby improving the quality of the cement. The heating box 68 serves as an energy supply device to supply energy to the heating tube 66, thereby heating the mixed cement raw materials to prevent them from solidifying inside the tank body 2, and to increase the molecular thermal motion of the raw materials, thereby improving the mixing reaction efficiency of the cement raw materials. The scraper 611 rotates with the stirring rod 63 to clean the inner wall of the tank body 2.

[0030] like Figure 3 As shown, the stirring structure 6 includes a transmission component 61, and the transmission component 61 includes a rectangular box and two gear discs. The outer walls of the two gear discs are meshed and connected with each other. The two gear discs are both located inside the rectangular box. The bottom end of the rectangular box is fixedly connected to the right side of the middle part of the top of the tank body 2. A driving motor 62 is fixedly installed on the right part of the top of the rectangular box. The output end of the driving motor 62 extends to the interior of the rectangular box. The output end of the driving motor 62 is fixedly connected to the top of the gear disc on the right, and the bottom end of the gear disc on the left extends to the interior of the tank body 2. A stirring rod 63 is fixedly connected to the bottom end of the gear disc on the left, and a plurality of stirring blades 64 are fixedly connected to the outer wall of the stirring rod 63.

[0031] By setting the stirring blade 64 and starting the motor 62, the stirring rod 63 is driven to rotate under the action of the transmission component 61, and the stirring rod 63 rotates and drives the stirring blade 64 to rotate, thereby stirring the raw materials, causing the raw material components to fully mix and react, thereby improving the quality of the cement.

[0032] like Figure 3 and Figure 5 As shown, a cavity 65 is opened inside the stirring blade 64, and a heating tube 66 is fixedly installed inside the cavity 65. A protective shell 67 is fixedly connected to the top of the left gear disk, and a heating box 68 is fixedly installed inside the protective shell 67. The output end of the heating box 68 is fixedly connected to the input end of the heating tube 66.

[0033] By setting up the heating tube 66 and starting the heating box 68, the heating box 68 acts as an energy supply device to supply energy to the heating tube 66, thereby heating the mixed cement raw materials to prevent them from solidifying inside the tank body 2, and to increase the molecular thermal motion of the raw materials, thereby improving the mixing reaction efficiency of the cement raw materials.

[0034] like Figure 4 As shown, the top and left and right sides of the bottom outer wall of the stirring rod 63 are fixedly connected with a sleeve 69, the interior of the four sleeves 69 are fixedly connected with an elastic telescopic rod 610, and the output ends of the elastic telescopic rod 610 at the left and right positions are fixedly connected with a scraper 611, and the upper and lower parts of the two scrapers 611 are slidingly connected to the inner walls of the four sleeves 69 near the outer walls of the sleeve 69 respectively.

[0035] By setting the elastic telescopic rod 610, the solenoid valve 5 is opened, and the cement is produced through the discharge pipe 4. At the same time, the motor 62 is continued to be driven, thereby driving the stirring rod 63 to rotate, and then the scraper 611 is scraped inside the tank body 2, thereby scraping off the raw materials adhering to the inner wall of the tank body 2. During this process, the elastic telescopic rod 610 presses the scraper 611 tightly against the inner wall of the tank body 2, thereby ensuring the cleaning effect.

[0036] like Figure 4 As shown, the front ends of the two scrapers 611 are each provided with a through hole penetrating the scraper 611 .

[0037] By providing the through holes, after the scraper 611 scrapes up the cement, the cement falls directly to the bottom of the tank body 2 through the through holes on the surface and is then discharged, thus avoiding the problem of cement falling on the scraper 611.

[0038] like Figure 7 As shown, the grinding structure 7 includes a grinding disc 71, the outer wall of the grinding disc 71 is fixedly connected to the top of the inner wall of the tank body 2, and a plurality of circular holes penetrating the grinding disc 71 are opened at the top of the grinding disc 71. The left and right positions of the outer wall of the top of the stirring rod 63 are rotatably connected to the grinding rollers 72, and the top of the outer wall of the grinding roller 72 overlaps with the top of the grinding disc 71.

[0039] By setting the grinding roller 72, after the cement raw materials are injected into the tank body 2 through the feed pipe 3, the motor 62 is started, and the stirring rod 63 is driven to rotate under the action of the transmission component 61, and then the grinding roller 72 is driven to rotate. At this time, the grinding roller 72 and the grinding disc 71 cooperate to crush the particles in the cement raw materials, thereby improving the fineness of the cement and thus improving the quality of cement production.

[0040] like Figure 6 As shown, an annular groove 74 is provided at the top of the inner wall of the tank body 2, and a rack 75 is fixedly connected to the top of the annular groove 74. The ends of the two grinding rollers 72 away from the stirring rod 63 are fixedly connected to a gear 73, and the outer wall of the gear 73 is meshed with the top of the rack 75.

[0041] By setting the gear 73 and the rack 75, the grinding roller 72 rotates around the axis of the stirring rod 63, while the gear 73 rotates on the surface of the rack 75, and the meshing action between the two drives the grinding roller 72 to rotate, thereby further improving the grinding effect and thus improving the quality of the cement product.

[0042] like Figure 7 As shown, the outer wall of the two grinding rollers 72 away from one end of the stirring rod 63 is rotatably connected to a baffle 76, and the baffle 76 is located above the grinding disc 71. The top and bottom of the baffle 76 away from the stirring rod 63 are rotatably connected to the top of the inner wall of the tank body 2.

[0043] By providing the baffle 76 , the baffle 76 can effectively prevent the cement raw material from falling into the annular groove 74 , thereby affecting the meshing between the gear 73 and the rack 75 .

[0044] The working principle of the present invention is as follows: when in use, the cement raw materials are injected into the tank body 2 through the feed pipe 3, and then the motor 62 is started. Under the action of the transmission assembly 61, the stirring rod 63 is driven to rotate, and then the grinding roller 72 is driven to rotate. At this time, the grinding roller 72 and the grinding disc 71 cooperate to crush the particles in the cement raw materials. While the grinding roller 72 rotates with the axis of the stirring rod 63 as the axis, the gear 73 rotates on the surface of the rack 75, and the meshing action between the two drives the grinding roller 72 to rotate, thereby further improving the grinding effect, and thus improving the quality of the cement product. In this process, the baffle 76 can effectively prevent the cement raw materials from falling into the annular groove 74, thereby affecting the meshing between the gear 73 and the rack 75. After the ground cement raw materials fall to the bottom of the tank body 2, the stirring rod 63 rotates and drives the stirring blades 64 to rotate, thereby stirring the raw materials, causing the raw materials to be The material components are fully mixed and reacted, thereby improving the quality of the cement. At the same time, the heating box 68 is started. The heating box 68 serves as an energy supply device to supply energy to the heating tube 66, thereby heating the mixed cement raw materials to prevent them from solidifying inside the tank body 2 and improving the molecular thermal motion of the raw materials, thereby improving the mixing reaction efficiency of the cement raw materials. After the mixing reaction is complete, the solenoid valve 5 is opened, and the cement is output through the discharge pipe 4. At the same time, the motor 62 is continued to be driven, thereby driving the stirring rod 63 to rotate, thereby causing the scraper 611 to scrape inside the tank body 2, thereby scraping off the raw materials adhering to the inner wall of the tank body 2. In this process, the elastic telescopic rod 610 presses the scraper 611 tightly against the inner wall of the tank body 2, thereby ensuring the cleaning effect. After the scraper 611 scrapes up the cement, it directly falls to the bottom of the tank body 2 through the through-hole support on the surface and is then discharged, avoiding the problem of cement falling on the scraper 611.

[0045] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
