Description

Technical Field

[0001] The invention relates to the technical field of kaolin production, in particular to a crushing and screening device for kaolin production. Background Art

[0002] Kaolin is a non-metallic mineral, a kind of clay and clay rock mainly composed of kaolinite clay minerals. The pure kaolin is white, fine, soft and has good physical and chemical properties such as plasticity and fire resistance. After kaolin is mined, in order to facilitate the use of kaolin, the kaolin material needs to be crushed and screened so that the kaolin material can be crushed into powder for subsequent use.

[0003] When the kaolin material is crushed, due to the presence of large pieces of kaolin ore in the kaolin material, it cannot enter the crushing roller for crushing quickly when passing through the crushing roller, and due to its large size, it may roll on the crushing roller for a period of time. The large pieces of kaolin ore are gradually crushed from the outside by the rotation of the crushing roller, and the time for processing the large pieces of kaolin ore will become longer. At this time, the kaolin material on the top will be piled up, which will not only reduce the feeding rate, but may also cause blockage in severe cases, thereby affecting the crushing efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

A first sliding protrusion 23 is fixed to the end of the slide rod 12. The first sliding protrusion 23 is slidably arranged in the first track groove 22. The first track groove 22 includes a horizontal portion 221, a first inclined portion 222 and a second inclined portion 223 which are connected in sequence.

[0035] In the present technical solution, the top of the processing box 1 is provided with an inclined surface matching the feed hopper 2 for feeding. When crushing and screening the kaolin, the blocky kaolin ore is first fed into the feed hopper 2, and the kaolin ore to be crushed is sent to the crushing roller 3 through the feed hopper 2. Fig.13 As shown in the figure, the servo motor 16 drives the rotating shaft 17 to rotate, and the rotating shaft 17 drives the crushing roller 3 to rotate. When the rotating shaft 17 rotates, the transmission gear 18 is driven to rotate. By meshing the transmission gears 18 at the ends of the two sets of rotating shafts 17, when the rotating shaft 17 connected to the servo motor 16 rotates, the two sets of transmission gears 18 can be driven to rotate, so that the two sets of crushing rollers 3 rotate in opposite directions, thereby completing the crushing of the kaolin. After the kaolin is crushed, the crushed material falls onto the screen 5 through the feeding trough 4. The powdered kaolin that is crushed and qualified can pass through the screen 5 and be discharged through the second discharge port 7. The block material that is crushed and unqualified cannot pass through the screen 5 and is screened out by the screen 5 and discharged from the first discharge port 6 along the screen 5, thereby completing the screening of the crushed kaolin; When the servo motor 16 drives the rotating shaft 17 to rotate, the rotating shaft 17 drives the first pulley 19 to rotate, the first pulley 19 drives the second pulley 20 to rotate through the transmission belt 21, the second pulley 20 drives the worm 9 to rotate, the worm 9 drives the worm wheel 10 to rotate, the rotation of the worm wheel 10 causes the slide bar 12 to slide in the annular slide groove 11, and the slide bar 12 drives the first sliding protrusion 23 to slide in the first track groove 22, as shown in FIG. Figure 4As shown in FIG. 1 , when the first sliding protrusion 23 slides from the horizontal portion 221 to the first inclined portion 222 and slides along the first inclined portion 222, the first sliding protrusion 23 drives the slide bar 12 to move rightward, as shown in FIG. Figure 5 and Figure 8 As shown, when the slide bar 12 moves to the right, it drives the connecting rod 13 to move to the right, and the connecting rod 13 drives the tamping rod 14 to move to the right, so that the tamping rod 14 extends from the inside of the processing box 1 to crush the large pieces of kaolin ore above the crushing roller 3 into smaller pieces of kaolin ore; when the first sliding protrusion 23 slides from the first inclined portion 222 to the second inclined portion 223 and slides along the second inclined portion 223, the first sliding protrusion 23 drives the slide bar 12 to move to the left and reset, so that the tamping rod 14 moves to the left and resets, and the tamping rod 14 is put into the processing box 1, and the above process is repeated. When the worm gear 10 rotates, the slide bar 12 can reciprocate left and right, so that the tamping rod 14 reciprocates left and right, so that the tamping rod 14 continues to crush the large pieces of kaolin ore; In this technical solution, the tamping rods 14 are symmetrically arranged on both sides of the processing box 1, and the tamping rods 14 on both sides are synchronously extended from the inside of the processing box 1 or retracted into the processing box 1, and the tamping rods 14 are arranged in several groups, which can more conveniently crush large pieces of kaolin ore and increase work efficiency.

[0036] In the second embodiment, when the tamping rod 14 is crushing, due to the soft nature of the kaolin ore, when the tamping rod 14 is inserted into the interior of the kaolin ore, the kaolin ore may be inserted by the tamping rod 14, and a pit or a hole may be formed, which will not cause the kaolin ore to be crushed and cracked, thereby failing to fully crush the large kaolin ore into smaller kaolin blocks. In view of this problem, this embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figure 1-Figure 14 A movable groove 24 is provided inside the processing box 1, a longitudinal plate 25 is fixed on the upper surface of the connecting rod 13, a hollow sleeve 26 is fixed on the surface of the longitudinal plate 25, a push rod 27 is slidably connected inside the hollow sleeve 26, a first hydraulic oil groove 28 is provided inside the processing box 1, a first piston plate 29 fixedly connected to the push rod 27 is slidably provided inside the first hydraulic oil groove 28, a second hydraulic oil groove 30 is provided inside the tamping rod 14, an oil delivery pipe 31 is provided between the second hydraulic oil groove 30 and the first hydraulic oil groove 28, a second piston plate 32 is slidably provided inside the second hydraulic oil groove 30, a core rod 33 is elastically connected to the surface of the second piston plate 32, a first slide groove 34 for the core rod 33 to slide is provided inside the tamping rod 14, a tamping column 35 is slidably provided at the end of the tamping rod 14, and the core rod 33 drives the tamping column 35 to perform telescopic action in the tamping rod 14 by sliding in the first slide groove 34; A first spring 36 is fixed between the inner wall of the second hydraulic oil groove 30 and the second piston plate 32. A movable groove 37 for sliding the oil delivery pipe 31 is provided inside the processing box 1. A guide groove 38 is provided inside the core rod 33. A limiting ball 39 is fixed at the end of the tamping column 35. The limiting ball 39 is slidably arranged in the guide groove 38, and the tamping column 35 is slidably connected to the core rod 33. A first rotating groove 40 is opened inside the connecting rod 13, and a first torsion spring 41 is arranged on the inner wall of the first rotating groove 40. The end of the ramming rod 14 is rotatably arranged in the first rotating groove 40, and the end of the ramming rod 14 is fixedly connected to the first torsion spring 41. A wedge block 42 is fixed on the lower surface of the ramming rod 14, and a resistance rod 43 for resisting the wedge block 42 is fixed on the inner wall of the movable groove 24.

[0037] In the present technical solution, when the first sliding protrusion 23 slides along the first inclined portion 222, the sliding rod 12 moves to the right. Figure 5 As shown, the connecting rod 13 drives the longitudinal plate 25 to move right, and the longitudinal plate 25 drives the hollow sleeve 26 to move right. When the ramming rod 14 extends from the inside of the processing box 1 but is not fully extended, the push rod 27 first slides inside the hollow sleeve 26 until the end of the push rod 27 conflicts with the longitudinal plate 25. Then, when the ramming rod 14 continues to extend from the inside of the processing box 1, the top plate conflicts with the longitudinal plate 25, prompting the push rod 27 to move right. The push rod 27 moves right to fill the hydraulic oil in the first hydraulic oil groove 28 into the second hydraulic oil groove 30 through the oil pipe 31. The oil pipe 31 is set as a hose and is not in a straightened state. The oil pipe 31 can move a certain distance with the ramming rod 14. The second hydraulic oil groove 30 is filled with hydraulic oil to push the second piston plate 32 to move right. The second piston plate 32 moves right to push the core rod 33 to move right in the first slide groove 34. At the same time, the first spring 36 is compressed and stored. Figure 7 As shown, when the core rod 33 moves to the right along the first slide groove 34, due to the interference between the limiting ball 39 and the guide groove 38, the limiting ball 39 will slide along the guide groove 38, and the limiting ball 39 drives the tamping column 35 to move, so that the tamping column 35 extends outward from the inside of the tamping rod 14, so that the tamping column 35 extends outward and inserts into the large piece of kaolin ore. The tamping column 35 provides a thrust to the large piece of kaolin ore on both sides of the tamping rod 14, so that the large piece of kaolin ore is more convenient to crack, thereby increasing the possibility of crushing the large piece of kaolin ore. When the tamping column 35 extends from the inside of the tamping rod 14, the tamping rod 14 drives the wedge block 42 to move to the abutment rod 43, and the wedge block 42 contacts the abutment rod 43. When the tamping rod 14 continues to move to the right, the abutment rod 43 abuts the wedge block 42, causing the wedge block 42 to deflect. The wedge block 42 drives the tamping rod 14 to deflect by a certain angle. At the same time, the first torsion spring 41 stores force, and the tamping rod 14 deflects by a certain angle to drive the extended tamping column 35 to rotate. The rotation increases the force-bearing surface between the tamping column 35 and the large piece of kaolin ore, so that the tamping column 35 can more conveniently pound the large piece of kaolin ore, further improving the possibility of crushing the large piece of kaolin ore. When the tamping rod 14 moves to the left for reset, the wedge block 42 moves to the left first, the wedge block 42 loses the resistance of the resistance rod 43, and the first torsion spring 41 releases force, causing the tamping rod 14 to rotate in the opposite direction and reset. At the same time, the connecting rod 13 drives the longitudinal plate 25 to move to the left and reset, and the longitudinal plate 25 drives the hollow sleeve 26 to move to the left and reset. The hollow sleeve 26 moves to the left, causing the top plate to lose the resistance of the longitudinal plate 25, and the first spring 36 releases force to push the second piston plate 32 to move to the left and reset, and the hydraulic oil inside the second hydraulic oil groove 30 is filled into the first hydraulic oil groove 28, so that the first piston plate 29 moves to the left and resets, and drives the top rod 27 to move to the left and reset. When the first spring 36 releases force and drives the second piston plate 32 to move to the left, it will drive the core rod 33 to move to the left and reset. The core rod 33 moves to the left and resets, and drives the tamping column 35 to be retracted into the tamping rod 14, and then the tamping rod 14 continues to move to the left and reset until the reset is completed.

[0038] In the third embodiment, before the large pieces of kaolin ore are crushed, the kaolin ore materials above will pile up. When the large pieces of kaolin ore are crushed, there will be a certain force between the kaolin ore materials due to the accumulation, which will cause the kaolin ore materials above to fail to be discharged in time, and the crushed large pieces of kaolin ore cannot be crushed faster by the crushing roller 3, thereby reducing the crushing efficiency. In view of this problem, this embodiment is an improvement made on the basis of the second embodiment. For details, please refer to Figure 1-Figure 14A straight rod 44 is slidably provided inside the processing box 1, one end of the straight rod 44 is fixedly connected to the first piston plate 29, and a third piston plate 45 is fixedly provided at the other end of the straight rod 44. A third hydraulic oil groove 46 for the third piston plate 45 to slide is provided inside the processing box 1, and a fourth piston plate 47 is slidably provided at the other end of the third hydraulic oil groove 46. A transmission rod 48 is fixed on the fourth piston plate 47, and a convex plate 49 is fixed at the other end of the transmission rod 48. A second slide groove 55 for the convex plate 49 to slide is provided inside the processing box 1, and a third slide groove 56 is provided inside the processing box 1. A moving plate 57 is slidably provided in the third slide groove 56, and a third spring 58 is provided between the top of the moving plate 57 and the top of the third slide groove 56. A knocking column 50 is elastically connected in the third slide groove 56, and the moving plate 57 drives the knocking column 50 to knock on the inner wall of the processing box 1 by sliding in the third slide groove 56; A second spring 51 is fixed inside the third slide groove 56, and the bottom end of the knocking column 50 is fixedly connected to the second spring 51. A limiting groove 52 for the knocking column 50 to slide is provided inside the processing box 1, and a second track groove 53 is provided on the movable plate 57. A second sliding protrusion 54 is fixed on the outer surface of the knocking column 50, and the second sliding protrusion 54 is slidably arranged in the second track groove 53. The second track groove 53 includes a first sliding portion 531 , a knocking portion 532 , and a second sliding portion 533 which are sequentially connected and arranged in communication. A rotating plate 534 is elastically arranged at the connection between the second sliding portion 533 and the first sliding portion 531 .

[0039] In the present technical solution, when the first piston plate 29 moves to the right, the straight rod 44 is driven to move to the right, and the straight rod 44 moves to the right, driving the third piston plate 45 to move to the right. The third piston plate 45 moves to the right and pushes the hydraulic oil in the third hydraulic oil groove 46 to move, so that the hydraulic oil pushes the fourth piston plate 47 to move upward. The fourth piston plate 47 moves upward and drives the convex plate 49 to move upward in the second slide groove 55 through the transmission rod 48. The convex plate 49 drives the moving plate 57 to slide upward in the third slide groove 56. The moving plate 57 moves upward to compress the third spring 58, so that the third spring 58 accumulates The moving plate 57 moves upward to make the second sliding protrusion 54 slide in the second track groove 53. When the second sliding protrusion 54 slides along the first sliding portion 531, the second sliding protrusion 54 drives the knocking column 50 to move leftward and compresses the second spring 51, so that the second spring 51 accumulates force. When the second sliding protrusion 54 slides to the knocking portion 532, the second spring 51 releases force, so that the second sliding protrusion 54 instantly slides along the knocking portion 532 to the second sliding portion 533, so that the second sliding protrusion 54 drives the knocking column 50 to knock the inner wall of the processing box 1; When the first piston plate 29 moves to the left and resets, the first piston plate 29 drives the straight rod 44 to move to the left and reset, and the third spring 58 releases force, pushing the moving plate 57 to move downward in the third slide groove 56 and reset, while driving the convex plate 49, the fourth piston plate 47 and the third piston plate 45 to reset. At this time, the second sliding protrusion 54 slides along the second sliding portion 533. When the second sliding protrusion 54 slides to the rotating plate 534, the rotating plate 534 can only be pressed as shown in the figure. Fig.11 The state shown in FIG. 1 is to rotate to the left and cannot rotate to the right, so that the rotating plate 534 can automatically return to the position after rotating to the left. Fig.11 Therefore, when the second sliding protrusion 54 slides to the rotating plate 534, the second sliding protrusion 54 abuts against the rotating plate 534, causing the rotating plate 534 to rotate leftward until the second sliding protrusion 54 is reset and the rotating plate 534 loses the abutment of the second sliding protrusion 54, causing the rotating plate 534 to reset to Fig.11 state, and then each time the moving plate 57 moves upward, due to the resistance of the rotating plate 534, the second sliding protrusion 54 can only slide along the first sliding portion 531, thereby completing the reciprocating knocking work of the knocking column 50 and improving the material feeding rate; In this technical solution, if Fig.14 As shown, a second rotating groove 59 is provided inside the movable plate 57, a rotating rod 60 is fixed at the end of the rotating plate 534, the rotating rod 60 is rotatably arranged in the second rotating groove 59, a second torsion spring 61 is sleeved on the circumference of the rotating rod 60, the a end of the second torsion spring 61 abuts against one side of the rotating plate 534, the b end of the second torsion spring 61 is fixedly connected to the inner wall of the second rotating groove 59, and a resisting block 62 is fixed inside the second rotating groove 59, and a limiting rod 63 abutting against the resisting block 62 is fixed on the rotating rod 60; as shown in FIG. Fig.14 As shown, the resistance block 62 is provided so that the rotating plate 534 can only be pressed Fig.14 When the state rotates to the right, when it rotates to the left, the limit rod 63 conflicts with the abutment block 62, making it impossible to rotate to the left. When the rotating plate 534 rotates to the right, the rotating plate 534 conflicts with the end a of the second torsion spring 61, so that the second torsion spring 61 accumulates force. When the rotating plate 534 loses the abutment, the second torsion spring 61 releases the force, so that the rotating plate 534 returns to its original position.
