[0024] Combined with reference Figure 1-Figure 5 The utility model provides a limestone pre-homogenizing device, comprising a homogenizing mixing drum 1 and a stirring frame 11 rotatably connected to the homogenizing mixing drum 1, the stirring frame 11 can perform homogenizing and stirring treatment on the limestone raw material particles entering the homogenizing mixing drum 1, a pretreatment drum 2 is arranged on the top of the homogenizing mixing drum 1, the pretreatment drum 2 comprises a mixing tank 21 and a feeding pipe 22 fixedly connected to the bottom of the mixing tank 21, a driving box 3 is fixedly penetrated on the top of the mixing tank 21, the feeding pipe 22 is fixedly penetrated on the top of the homogenizing mixing drum 1, and is extended inwardly to be provided The discharge pipe 22 can be used to transport limestone particle raw materials into the homogenizing mixing drum 1. At least two pairs of conveying pipes 4 for limestone raw materials are fixedly penetrated on the mixing tank 21. A first auger shaft 41 is rotatably connected in the conveying pipe 4. A discharge port 43 is opened on the conveying pipe 4. The discharge port 43 corresponds to the mixing tank 21. A transmission shaft 5 is rotatably connected in the driving box 3. A motor 6 that drives the transmission shaft 5 to rotate through a reducer is arranged on the top of the driving box 3. A transmission assembly 7 for synchronously driving the two pairs of first auger shafts 41 to rotate is arranged on the transmission shaft 5.

[0025] A feed hopper 42 is provided on the conveying pipe 4, one end of which is fixedly connected to the driving box 3, and the axial end of the first auger shaft 41 arranged in the conveying pipe 4 extends into the driving box 3. The position of the feed hopper 42 can be used to load limestone raw materials with the help of conveying equipment.

[0026] The transmission assembly 7 includes a toothed disc 71 fixedly connected to the transmission shaft 5 and two pairs of bevel gears 72 meshingly connected to the toothed disc 71 . The bevel gears 72 are fixedly connected to the shaft end of the first auger shaft 41 .

[0027] Specifically, by feeding limestone raw materials into the feed hopper 42, the motor 6 can drive the transmission shaft 5 to rotate through the reducer, and the rotation of the gear plate 71 can synchronously drive the two pairs of bevel gears 72 to rotate, so that the first auger shaft 41 in the conveying pipe 4 can drive the limestone raw materials to move into the mixing tank 21.

[0028] It is worth noting that since the toothed disc 71 drives the two pairs of bevel gears 72 to rotate synchronously, there is inconsistency in the rotation direction. Therefore, by changing the direction of the auger on the first auger shaft 41 in the conveying pipe 4, it is possible to ensure that the limestone raw material is fed into the mixing tank 21 facing the direction of the auger.

Under the action of the dividing plate 8 driving the driven rod 91 to rotate, the rolling roller 92 can roll on the inner bottom wall of the inner bottom of the mixing tank 21, which can facilitate the rolling of the limestone material, thereby changing the particle size of the limestone raw material to promote homogenization processing.

[0034] The feeding assembly 10 includes a second auger shaft 101 fixedly connected to the bottom end of the driven rod 91 and a stirring rod 102 fixedly connected to the shaft of the second auger shaft 101 .
