The second bevel gear 8 is meshed with the first bevel gear 7 to drive the connecting shaft 6 to rotate. The end of the connecting shaft 6 located inside the crushing barrel 2 is connected to the extrusion plate 3 through a connecting rod pair, so that the rotation of the connecting shaft 6 is converted into reciprocating movement of the extrusion plate 3. The connecting rod pair includes a first connecting rod 9 and a second connecting rod 10. One end of the first connecting rod 9 is fixedly connected to the connecting shaft 6, and the other end of the first connecting rod 9 is hinged to one end of the second connecting rod 10, and the other end of the second connecting rod 10 is hinged to the extrusion plate 3.

[0032] like Figure 1-Figure 3As shown, the grinding mechanism includes a grinding cylinder 19, a driving assembly and a grinding roller 20. Two shaft seats 21 are installed on the box body 1. The two ends of the grinding cylinder 19 are supported on the box body 1 and rotate relative to the box body 1 through the shaft seats 21. There are two grinding rollers 20. The two grinding rollers 20 are installed in parallel and side by side in the grinding cylinder 19. Both ends of the grinding rollers 20 extend out of the grinding cylinder 19 and are rotatably connected to the box body 1. A sealing structure that can rotate relative to the grinding cylinder 19 can be installed at the end of the grinding cylinder 19 to prevent the material in the grinding cylinder 19 from falling from the two ends of the grinding cylinder 19. The sealing structure is an application of the prior art, and its structure is not repeated here. The first gear 2 is fixedly connected to one end of the grinding roller 20 that passes through the grinding cylinder 19 and the box body 1. 2. The two first gears 22 on the two grinding rollers 20 are meshed. Through meshing transmission, the two grinding rollers 20 can rotate in opposite directions, thereby grinding the refractory raw materials. A second gear 23 and a third gear 24 are rotatably installed on the box body 1. The second gear 23 and the third gear 24 are coaxially installed to achieve synchronous rotation. The second gear 23 is meshed with one of the first gears 22. A gear ring 25 is integrally machined on the outer circumferential surface of the end of the grinding cylinder 19 close to the first gear 22. The third gear 24 is meshed with the gear ring 25. Through meshing transmission, the grinding cylinder 19 is driven to rotate. During the rotation of the grinding cylinder 19, the refractory raw materials inside are driven to roll and fall between the two grinding rollers 20, thereby improving the grinding efficiency.

[0033] The driving assembly includes a driving motor 28 and two driving wheels 29. The driving motor 28 is installed on the box body 1, one of the driving wheels 29 is fixedly connected to the output shaft of the driving motor 28, and the other driving wheel 29 is coaxially installed on one of the grinding rollers 20. The two driving wheels 29 transmit power to each other. The driving wheel 29 uses but is not limited to a sprocket or a pulley. The driving motor 28 drives the driving wheel 29 to rotate, and the power transmission between the two driving wheels 29 drives one of the grinding rollers 20 to rotate, and then the rotation of the grinding roller 20 and the grinding cylinder 19 is realized through the meshing of gears.

[0034] like Figure 3 As shown, in order to further improve the uniform distribution of the refractory raw materials in the grinding cylinder 19, a spiral blade 26 is processed on the inner wall of the grinding cylinder 19. As the grinding cylinder 19 rotates, the spiral blade 26 can realize the transportation of the material at one end of the grinding cylinder 19 to the inside of the spiral cylinder. On the grinding cylinder 19, a plurality of drop holes 27 are evenly processed along its circumferential direction and penetrate its thickness direction. The aperture of the drop hole 27 is processed according to the particle size requirement after grinding. The refractory material that reaches the required particle size after grinding passes through the drop hole 27 and falls to the outside of the grinding cylinder 19.

[0035] like Figure 2As shown, a receiving bin 30 is processed on the box body 1 and located at the bottom of the grinding cylinder 19. The refractory materials falling from the drop holes 27 of the grinding cylinder 19 fall into the receiving bin 30 for collection. The receiving bin 30 is processed into a cone shape to facilitate the collection of refractory materials. A discharge port 31 is processed at the bottom of the receiving bin 30, and a butterfly valve 32 is connected to the discharge port 31. By connecting an external pipeline to the butterfly valve 32 and opening the butterfly valve 32, the refractory materials in the receiving bin 30 can be transported to a designated position.

[0036] like Figure 2 As shown, a drop hopper 34 is connected between the crushing cylinder 2 and the grinding cylinder 19. The drop hopper 34 is installed on the box body 1, and the upper end of the drop hopper 34 is connected to the drop port 11. When the pressure plate 12 is opened, the refractory material in the crushing cylinder 2 falls into the drop hopper 34 from the drop port 11, and the lower end of the drop hopper 34 is connected to the grinding cylinder 19 through a rotary joint 33. The rotary joint 33 is located at the end of the grinding cylinder 19 close to the crushing cylinder 2. The refractory material dropped into the drop hopper 34 is transported to the inside of the grinding cylinder 19 through the rotary joint 33.

[0037] The working principle of the utility model is:

[0038] When in use, the cover plate 16 is opened to put the refractory raw materials into the crushing drum 2 through the feed hopper 15, the cover plate 16 is closed, and the power motor 4 is started. The power motor 4 drives the transmission shaft 5 to rotate, and the two connecting shafts 6 are driven to rotate through the meshing of the first bevel gear 7 and the second bevel gear 8. The connecting shaft 6 drives the two extrusion discs 3 to move relatively close to or away from each other through the transmission of the first connecting rod 9 and the second connecting rod 10. When they are close to each other, the two extrusion discs 3 squeeze and crush the refractory raw materials with larger particle sizes to reduce the particle size of the raw materials, which is convenient for subsequent grinding;

[0039] After crushing is completed, the flap cylinder 14 drives the pressure plate 12 to rotate, the feeding port 11 is opened, and the crushed raw materials fall from the feeding port 11 into the feeding hopper 34 and enter the grinding cylinder 19 through the rotary joint 33. When feeding, the movement of the extrusion plate 3 can accelerate the falling speed of the raw materials. The driving motor 28 drives one of the grinding rollers 20 to rotate. Through the meshing of the two first gears 22, the two grinding rollers 20 rotate in opposite directions. The raw materials are ground during the rotation to further reduce the particle size of the raw materials. The grinding cylinder 19 is driven to rotate through the meshing of the first gear 22 and the second gear 23 and the meshing of the third gear 24 and the gear ring 25. The rotation of the grinding cylinder 19 drives the raw materials inside to be lifted and fall between the two grinding rollers 20, saving grinding time and improving grinding efficiency. The raw materials that reach the required particle size after grinding fall out from the feeding hole 27 on the circumferential surface of the grinding cylinder 19 and fall into the receiving bin 30. When the raw materials are completely ground, the butterfly valve 32 is opened to discharge the raw materials outward through the discharge port 31.

[0040] The above description is only a preferred embodiment of the utility model, and is not intended to limit the scope of implementation of the utility model. That is, all equivalent changes and modifications made according to the content of the patent application scope of the utility model should belong to the technical scope of the utility model.
