A support column 8 is arranged at the bottom of the dust removal barrel 6. The support column 8 has a supporting effect on the dust removal barrel 6 and can improve the stability of the dust removal barrel 6.

[0034] Example 2

[0035] On the basis of the above-mentioned embodiment 1, Figure 1 As shown, the driving mechanism includes a driving motor 9, which is arranged on the base 1. The output end of the driving motor 9 is connected to the input end of the reducer 10. The output end of the reducer 10 is provided with a driving gear 11, which is meshed with a gear ring 12, and the gear ring 12 is arranged outside the ball mill cylinder 3.

[0036] The working principle and beneficial effects of the above technical solution are as follows: starting the drive motor 9 can drive the drive gear 11 at the output end of the reducer 10 to rotate, and the engagement of the drive gear 11 with the gear ring 12 can drive the gear ring 12 to rotate, thereby driving the ball mill cylinder 3 to rotate between the two fixed plates 2, thereby realizing the driving of the ball mill cylinder 3, and facilitating the completion of the ball milling work of the stone.

[0037] Example 3

[0038] On the basis of Example 1 or 2, Figure 2 As shown, a conveying shaft 13 is arranged inside the conveying pipe 4 , a spiral blade 14 is arranged outside the conveying shaft 13 , and one end of the conveying shaft 13 extends to the outside of the conveying pipe 4 and is provided with a conveying motor 15 .

[0039] The working principle and beneficial effects of the above technical solution are as follows: starting the conveying motor 15 can drive the conveying shaft 13 to rotate, and the rotation of the conveying shaft 13 drives the spiral blade 14 to rotate, thereby conveying the stone entering the conveying pipe 4 to the ball mill cylinder 3, realizing automatic feeding.

[0040] Example 4

[0041] On the basis of any one of Examples 1-3, Figure 1 , Figure 2 , Figure 7 As shown, a support ring 16 is arranged outside the ball mill cylinder 3, and the side wall of the support ring 16 is connected to the side wall of the fixed plate 2 through a connecting column. The outer wall of the ball mill cylinder 3 is rotatably connected to the inner wall of the support ring 16, and a discharge port 17 is arranged on the bottom wall of the support ring 16. A discharge screen 18 is arranged in the discharge port 17, and a receiving vehicle 19 is arranged below the discharge port 17. A discharge port 20 is arranged on the side wall of the ball mill cylinder 3, and the discharge port 20 corresponds to the discharge port 17.

[0042] The working principle and beneficial effects of the above technical solution are as follows: when the ball mill cylinder 3 rotates, the discharge port 20 of the ball mill cylinder 3 can be intermittently connected with the discharge port 17. When the particle size of the stone in the ball mill cylinder 3 after crushing is smaller than the sieve hole diameter of the discharge screen 18, the crushed stone can pass through the discharge screen 18 into the discharge port 17 and finally fall into the receiving vehicle 19, while the stone with a particle size larger than the sieve hole diameter of the discharge screen 18 continues to rotate with the ball mill cylinder 3 and continues to be crushed. By setting the discharge screen 18, the crushed stone can be screened so that the particle size of the stone entering the receiving vehicle 19 is smaller than the sieve hole diameter of the discharge screen 18. The discharge screen 18 is detachably connected to the inner wall of the discharge port 17, and the user can select different discharge screens 18 according to different needs, thereby improving the scope of application.

[0043] Example 5

[0044] On the basis of any one of Examples 1-4, Figure 2 , Figure 3As shown, the dust removal mechanism includes a driving shaft 22, the upper end of the driving shaft 22 is rotatably connected to the top wall of the dust removal cylinder 6, a dust removal motor 23 is arranged at the upper end of the dust removal cylinder 6, the output end of the dust removal motor 23 is connected to the driving shaft 22, a dust removal fan blade 24 is arranged on the outer wall of the driving shaft 22, a dust collection cylinder 25 is arranged below the dust removal fan blade 24, a gap is arranged between the outer wall of the dust collection cylinder 25 and the inner wall of the dust collection cylinder 6, a plurality of adsorption holes are arranged on the inner wall of the dust collection cylinder 25, connecting rings 26 are symmetrically arranged on the upper and lower sides of the dust collection cylinder 25, the connecting ring 26 is in a hollow truncated cone shape, one end of the connecting ring 26 is connected to the dust collection cylinder 25, and the other end of the connecting ring 26 is connected to the inner wall of the dust collection cylinder 6, and the two connecting rings 26, the outer side of the dust collection cylinder 25 and the inner side of the dust collection cylinder 6 constitute a dust collection cavity 27;

[0045] A collection box 28 is disposed outside the dust removal cylinder 6 , and the collection box 28 is connected to the interior of the dust collection cavity 27 through a dust removal channel 29 .

[0046] The working principle and beneficial effects of the above technical solution are as follows: when stones are put into the feeding pipe 7, the stones move and collide with each other in the feeding pipe 7 and the dust removal pipe to generate stone dust, and the dust removal motor 23 is started. The rotation of the dust removal motor 23 drives the driving shaft 22 to rotate, and the rotation of the driving shaft 22 drives the dust removal fan blades 24 to rotate. The rotation of the dust removal fan blades 24 can suck the stone dust in the dust removal pipe to the upper position inside the dust removal pipe, and then enter the dust collection cavity 27 through the dust collection cylinder 25. Since the connecting ring 26 is in the shape of a hollow truncated cone, the stone dust can accumulate on the side wall of the lower connecting ring 26, and slide downward along the side wall of the connecting ring 26, and finally enter the collecting box 28 through the inclined dust removal channel 29, completing the stone dust collection. In order to collect the stone dust, an air suction fan and a spray mechanism are also arranged in the collection box 28. The air suction fan can accelerate the stone dust to enter the collection box 28, thereby improving the collection efficiency of the stone dust. At the same time, the stone dust entering the collection box 28 is sprayed by the spray mechanism, thereby achieving the effect of dust reduction, preventing the stone dust from diffusing out of the collection box 28, and improving the collection capacity of the collection box 28 for stone dust. The spray mechanism is arranged in the collection box 28, so as to avoid spraying the stone in the dust removal tube 6, thereby ensuring the dry ball grinding of the stone. The dust removal mechanism can collect the stone dust in the dust removal tube 6, and prevent the stone dust from diffusing to the external environment through the feed pipe 7, thereby protecting the working environment and the health of the staff.

[0047] Example 6

[0048] On the basis of Example 5, Figure 2 , Figure 3 As shown, a reciprocating screw 30 is arranged at the lower end of the driving shaft 22, a sliding block 31 is slidingly arranged outside the reciprocating screw 30, a dust removal net 32 ​​is arranged outside the sliding block 31, and the outer wall of the dust removal net 32 ​​is slidably connected to the inner wall of the dust collection cylinder 25 up and down.

[0049] The working principle and beneficial effects of the above technical solution are as follows: the stone dust in the dust collecting cylinder 6 can pass through the dust collecting net 32 ​​to reach the dust collecting cylinder 25. Part of the stone dust will adhere to the inner wall of the dust collecting cylinder 25 when passing through the dust collecting cylinder 25. When the stone dust accumulates more, the dust collecting cylinder 25 will be blocked, affecting the collection effect of the stone dust. Therefore, a reciprocating screw 30 is arranged at the lower end of the driving shaft 22. When the driving shaft 22 rotates, the reciprocating screw 30 can be driven to rotate. Since the outer wall of the dust collecting net 32 ​​is slidably connected with the inner wall of the dust collecting cylinder 25 up and down, the reciprocating screw 30 can drive the slider 31 to move up and down on the outside of the reciprocating screw 30 when the reciprocating screw 30 rotates. The slider 31 drives the dust removal net 32 ​​to reciprocate up and down on the inner wall of the dust collection tube 25 by the reciprocating motion. The outer periphery of the dust removal net 32 ​​contacts the inner wall of the dust collection tube 25 to scrape off the stone dust accumulated on the inner wall of the dust collection tube 25, and makes the stone dust fall into the dust collection cavity 27, so as to facilitate the collection box 28 to collect the stone dust, thereby improving the removal and collection effect of the dust removal mechanism on the stone dust, and reducing the diffusion of the stone dust. At the same time, the stone dust attached to the inner wall of the dust collection tube 25 is removed by the dust removal net 32, so as to extend the service life of the dust collection tube 25, reduce the replacement and cleaning frequency of the dust collection tube 25, and reduce the labor intensity of the staff.

[0050] Example 7

[0051] On the basis of Example 6, Figure 5 , Figure 6 As shown, a feed screen 33 is provided in the connecting pipe 5, and the feed screen 33 is located at the connection between the connecting pipe 5 and the dust removal cylinder 6;

[0052] A connecting shaft 34 is provided at the lower end of the reciprocating screw 30, and the upper end of the connecting shaft 34 is fixedly connected to the lower end of the reciprocating screw 30. A crushing block 35 is provided at the lower end of the connecting shaft 34. The crushing block 35 is truncated cone-shaped. The diameter of the upper end of the crushing block 35 is smaller than the diameter of the lower end of the crushing block 35. The diameter of the lower end of the crushing block 35 is smaller than the diameter of the inner wall of the dust collecting tube 6. A toggle plate 36 is provided on the lower surface of the crushing block 35, and one end of the toggle plate 36 contacts the inner wall of the dust collecting tube 6. A plurality of crushing protrusions 37 are provided on the outer wall of the crushing block 35, and a plurality of crushing teeth 38 are provided on the inner wall of the dust collecting tube 6.

[0053] The working principle and beneficial effects of the above technical solution are as follows: the rotation of the reciprocating screw 30 can drive the connecting shaft 34 to rotate, and the rotation of the connecting shaft 34 can drive the crushing block 35 to rotate. When the stone falls into the dust removal tube 6 through the feeding pipe 7, the stone first contacts the crushing block 35, and the rotation of the crushing block 35 can drive the crushing spurs 37 to rotate. The crushing spurs 37 can drive the stone to move in the dust removal tube 6 and crush the stone under the action of the crushing teeth 38, thereby reducing the size of the stone. Since the crushing block 35 is set to a truncated cone shape, the stone can gradually move downward as the particle size decreases until it falls below the crushing block 35. At this time, the particle size of the stone is smaller than the sieve hole diameter of the feeding screen 33, and the stone is moved downward. The stone under the crushing block 35 can enter the connecting pipe 5 through the feed screen 33, and then be transported to the ball mill cylinder 3 through the conveying pipe 4 for ball milling and crushing. When the crushing block 35 rotates, it can drive the toggle plate 36 to rotate. The toggle plate 36 can toggle the stone under the crushing block 35, and make the stone quickly pass through the feed screen 33 under the centrifugal action, thereby improving the conveying efficiency of the stone. By setting the crushing block 35, the stone can be preliminarily crushed, thereby improving the crushing and grinding efficiency of the ball mill for the stone. In addition, the crushing block 35 is in the shape of a truncated cone. Through the cooperation of the crushing thorns 37 and the crushing teeth 38, the stone can be crushed step by step, thereby improving the crushing efficiency of the crushing block 35 for the stone.

[0054] Example 8

[0055] On the basis of Example 7, Figure 2-Figure 4 As shown, a pressure block 39 is arranged outside the connecting shaft 34, and a sliding hole is arranged at the center of the pressure block 39. The pressure block 39 is slidably connected to the outer wall of the connecting shaft 34 up and down through the sliding hole. A limiting groove is arranged on the inner wall of the sliding hole. A limiting bar is arranged on the outer wall of the connecting shaft 34. The limiting bar is slidably connected to the inner wall of the limiting groove up and down. The pressure block 39 is truncated cone-shaped. The diameter of the upper end of the pressure block 39 is smaller than the diameter of the lower end of the pressure block 39. The diameter of the lower end of the pressure block 39 is smaller than the diameter of the inner wall of the dust removal cylinder 6. A plurality of anti-slip teeth 40 are arranged on the lower surface of the pressure block 39. A plurality of mounting holes 41 are arranged in the pressure block 39. A sliding column 42 is slidably arranged in the mounting hole 41. The upper end of the sliding column 42 is connected to the lower surface of the slider 31. A connecting spring 43 is sleeved on the outside of the sliding column 42. One end of the connecting spring 43 is connected to the lower surface of the slider 31, and the other end of the connecting spring 43 is connected to the upper surface of the pressure block 39.

[0056] The working principle and beneficial effects of the above technical solution are as follows: when the slider 31 reciprocates up and down on the reciprocating screw 30, it can drive the sliding column 42 to reciprocate up and down. When the sliding column 42 moves downward, the connecting spring 43 drives the pressing block 39 to move downward. The pressing block 39 can press the stone between the pressing block 39 and the crushing block 35, and by increasing the pressure of the stone, the contact effect between the stone and the crushing block 35 is enhanced to prevent the stone from jumping, and the crushing effect of the crushing block 35 on the stone is further improved. The anti-skid teeth 40 are arranged on the lower surface of the pressing block 39, and the anti-skid teeth 40 can prevent the rolling of the stone, which is convenient for the crushing spurs 37 to crush the stone As the slider 31 gradually moves downward, the pressure of the pressing block 39 on the stone gradually increases, which can crush the stone and accelerate the falling of the stone. When the slider 31 gradually moves upward, the space between the pressing block 39 and the crushing block 35 increases, which is convenient for replenishing the stone into the dust collecting tube 6. The diameter of the lower end of the pressing block 39 is smaller than the diameter of the inner wall of the dust collecting tube 6, which can make a gap between the pressing block 39 and the inner wall of the dust collecting tube 6, ensuring the accelerated passage of stone dust and improving the collection efficiency of stone dust. In the process of stone ball milling, the stone can be automatically conveyed to the feed pipe 7 through the conveyor belt, realizing automatic ball milling of the stone and improving the ball milling efficiency.
