[0031] Reference Figure 1-3 A limestone batching device comprises a batching pipe body 1, a stirring assembly 2 is arranged in the middle of the batching pipe body 1, a high-quality limestone feed pipe 11 and a low-quality limestone feed pipe 12 are respectively connected and arranged on the top of the batching pipe body 1, the high-quality limestone feed pipe 11 and the low-quality limestone feed pipe 12 are arranged in a mirror image, a pushing assembly 3 is arranged on the high-quality limestone feed pipe 11 and the low-quality limestone feed pipe 12, and a feeding pipe 13 is arranged on the high-quality limestone feed pipe 11 and the low-quality limestone feed pipe 12;

[0032] When in use, high-quality limestone and low-quality limestone enter the high-quality limestone feeding pipe 11 and the low-quality limestone feeding pipe 12 respectively from the feeding pipe 13, and are pushed into the batching pipe body 1 respectively through the pushing component 3, and are dispersed and mixed through the stirring component 2, so that the two qualities of limestone can be discharged into the batching pipe body 1 at the same time, and are fully stirred and mixed by the stirring component 2, so that the two qualities of limestone are mixed first and then discharged into the cement, thereby ensuring the quality of cement production.

[0033] Reference Figure 2 A weighing device 14 is provided at the bottom of the inner wall of the high-quality limestone feed pipe 11 and the low-quality limestone feed pipe 12, which can more accurately control the input amount of limestone of each quality.

[0034] Reference Figure 1-2 A flow meter 15 is provided on the feeding pipe 13. In the present embodiment, the flow meter 15 is an electromagnetic flow meter 15, which can accurately control the discharge amount.

[0035] Reference Figure 1-3 The push assembly 3 includes a cylinder 31 and a push plate 32. The cylinder 31 is fixedly arranged on the outer wall of the high-quality limestone feed pipe 11 and the low-quality limestone feed pipe 12. The push plate 32 is located in the high-quality limestone feed pipe 11 and the low-quality limestone feed pipe 12. The cylinder 31 drives the push plate 32 to move.

[0036] When in use, the cylinder 31 drives the push plate 32 to push the limestone powder dropped on the weigher 14 into the batching pipe body 1 in the high-quality limestone feeding pipe 11 and the low-quality limestone feeding pipe 12 for mixing.

[0037] Reference Figure 2-3 A bottom scraper 33 is also provided at the bottom of the push plate 32. The cross section of the bottom scraper 33 is triangular, and the bottom scraper 33 abuts against the surfaces of the high-quality limestone feed pipe 11, the low-quality limestone feed pipe 12, and the weighing device 14, which can clean the limestone powder more thoroughly.

[0038] Reference Figure 1-2 The high-quality limestone feed pipe 11 and the low-quality limestone feed pipe 12 are also provided with an air inlet 16, the air inlet 16 is connected to a blower 17, and an air guide plate 18 is provided at the lower end of the air inlet 16;

[0039] When in use, the blower 17 blows air into the pipe and the wind guide plate 18 can blow the wind toward the middle of the batching pipe body 1 to prevent the limestone powder from splashing and flowing back to the weighing device 14 during stirring and mixing, thereby affecting the weighing accuracy.

[0040] Reference Figure 1-2 The stirring assembly 2 includes a driving motor 21, a rotating shaft 22, a scattering roller 23 and a spiral blade 24.

[0041] When in use, the driving motor 21 drives the rotating shaft 22 to rotate, driving the scattering roller 23 to scatter and mix the limestone powder. At the same time, the limestone powder can be further mixed when it falls onto the spiral blades 24, and the limestone powder can be squeezed out to prevent the discharge end of the batching pipe body 1 from being blocked.

[0042] Reference Figure 2 The breaking roller 23 is located between the discharge end of the high-quality limestone feed pipe 11 and the discharge end of the low-quality limestone feed pipe 12, and can more accurately stir and mix the newly fallen limestone powder.
