[0027] Now, the present invention will be further described in detail with reference to the accompanying drawings.

[0028] As Figure 1-2 shown, an iron tailings sand making equipment includes a fixed box 1 and a grinding and crushing mechanism. The fixed box 1 is horizontally arranged, and the grinding and crushing mechanism is arranged in the fixed box 1. The grinding and crushing mechanism includes a crushing component and a grinding component.

[0029] The crushing component includes a connecting cylinder 2, a driving unit, a crushing unit, a limiting unit and a vibration unit. The connecting cylinder 2 is horizontally arranged in the fixed box 1. The driving unit is arranged on one side of the fixed box 1. The driving unit includes a motor 3, a fixed rod 4 and a rotating rod 5. The rotating rod 5 is horizontally arranged in the fixed box 1. The rotating rod 5 is coaxially arranged with the connecting cylinder 2. The motor 3 is horizontally arranged at one end of the fixed box 1. One end of the rotating rod 5 passes through the fixed box 1 and is installed on the motor 3. The fixed rod 4 is L-shaped, and the motor 3 is connected to the fixed box 1 through the fixed rod 4;

[0030] The crushing unit is arranged in the connecting cylinder 2, and the crushing unit includes a driven rod 6, a positioning bar 7, a limiting ring 8, a first magnet 9, a second magnet 10 and a cutting unit. The driven rod 6 is horizontally arranged in the connecting cylinder 2, and the driven rod 6 is coaxially arranged with the connecting cylinder 2. The positioning bar 7 is horizontally arranged on the outer ring of the driven rod 6, and the limiting ring 8 is sleeved on the end of the driven rod 6 close to the rotating rod 5. The end of the rotating rod 5 away from the motor 3 is provided with a cylindrical groove, and the inner wall of the groove is provided with a U-shaped opening groove. The end of the driven rod 6 close to the motor 3 extends into the groove, and the positioning bar 7 is located in the opening groove. The driven rod 6 is connected to the rotating rod 5 through the positioning bar 7. The first magnet 9 is arranged at the bottom end inside the groove, and the second magnet 10 is arranged on the end of the driven rod 6 located inside the groove. The first magnet 9 and the second magnet 10 repel each other.

[0031] There are several cutting units, each of which is evenly arranged on the driven rod 6. The cutting unit includes a ring 11, a first spring 12 and a blade 13. The ring 11 is sleeved on the driven rod 6, and the ring 11 is slidably connected to the driven rod 6. There are several blades 13, each of which is evenly arranged along the outer circumference of the ring 11. The first spring 12 is sleeved on the driven rod 6, and the first spring 12 is slidably connected to the driven rod 6. The two ends of the first spring 12 are respectively against two adjacent rings 11.

[0032] When the material needs to be crushed here, the motor 3 is first operated, and the motor 3 drives the rotating rod 5 to rotate. The rotating rod 5 realizes the rotation of the driven rod 6 through the positioning bar 7, and at the same time realizes the rotation of the ring 11. The ring 11 drives the blade 13 to rotate, and the material is crushed by the blade 13. Here, the crushing unit is limited by the limit ring 8 and the push ring 20, so that the crushing unit can only slide freely on the driven rod 6 between the limit ring 8 and the push ring 20.

[0033] like Figure 3-4As shown, the limiting unit is arranged between the outer circle of the connecting cylinder 2 and the inner wall of the top end of the fixed box 1. There are two limiting units, which are respectively arranged at both ends of the connecting cylinder 2. The limiting unit includes a limiting rod 14, a limiting plate 15, a limiting block 16 and a second spring 17. The limiting plate 15 is arranged above the connecting cylinder 2. The limiting plate 15 is arc-shaped, and the center of the limiting plate 15 is located on the connecting cylinder 2. The limiting rod 14 is arranged between the limiting plate 15 and the inner wall of the top end of the fixed box 1. One end of the limiting rod 14 is connected to the middle of the limiting plate 15, and the other end of the limiting rod 14 is connected to the inner wall of the top end of the fixed box 1. An arc-shaped limiting groove is provided at one end of the limiting plate 15 close to the connecting cylinder 2. The limiting block 16 is arranged in the limiting groove. The connecting cylinder 2 is slidably connected to the limiting groove through the limiting block 16. There are two second springs 17, and both second springs 17 are arranged in the limiting groove.

One end of the second spring 17 is connected to the limiting block 16, and the other end of the second spring 17 is connected to the inner wall of one end of the limiting groove;

[0034] A rotating unit is provided at one end of the connecting cylinder 2 close to the rotating rod 5. The rotating unit includes a abutting rod 18 and a pushing rod 19. The abutting rod 18 is horizontally arranged on the outer circle of one end of the connecting cylinder 2. The pushing rod 19 is arranged between the abutting rod 18 and the rotating rod 5. One end of the pushing rod 19 abuts against the abutting rod 18, and the other end of the pushing rod 19 is hinged to the outer circle of the rotating rod 5. A torsion spring is provided at the hinge of the pushing rod 19 and the rotating rod 5;

[0035] The vibration unit is arranged at one end of the fixed box 1 away from the motor 3, and the vibration unit is connected to the driven rod 6;

[0036] The grinding assembly is arranged between the connecting cylinder 2 and the inner wall of the bottom end of the fixed box 1, and the grinding assembly is connected to the connecting cylinder 2.

[0037] Here, the rotating rod 5 rotates, and at the same time drives the pushing rod 19 to rotate. The pushing rod 19 drives the abutting rod 18 to rotate, and the abutting rod 18 drives the connecting cylinder 2 to rotate. Here, the restoring force of the torsion spring at the hinge of the pushing rod 19 and the rotating rod 5 can realize the rotation of the connecting cylinder 2. Only when the restoring force of the second spring 17 inside the limiting groove is greater than the restoring force of the torsion spring, can the pushing rod 19 be separated from the abutting rod 18 at this time.

[0038] Here, when the connecting cylinder 2 rotates, at the same time, it slides through the limiting block 16 in the limiting groove. At this time, one of the two second springs 17 at both ends of the limiting block 16 in the limiting groove is in a compressed state, and the other is in a stretched state. Through the restoring force of the second spring 17, not only can the pushing rod 19 and the abutting rod 18 be assisted in separating, but also the restoring force of the connecting cylinder 2 can be realized, so that the connecting cylinder 2 moves to the initial position.

[0039] By rotating the connecting cylinder 2, the turnover of the material is realized, thereby increasing the contact area between the blade 13 and the material, improving the crushing effect and working efficiency.

[0040] Such as Figure 5-6 As shown, preferably, in order to push the driven rod 6 and improve the crushing effect, the vibration unit includes a pushing ring 20, a communicating pipe 21, a abutting ball 22, an auxiliary unit and a moving unit. The pushing ring 20 is sleeved on the driven rod 6, and the pushing ring 20 is slidably connected with the driven rod 6. The abutting ball 22 is arranged at one end of the fixed box 1. The communicating pipe 21 is arranged between the pushing ring 20 and the abutting ball 22.

[0041] Preferably, in order to realize reciprocating movement, the auxiliary unit is arranged on the side of the abutting ball 22 away from the communicating pipe 21. The auxiliary unit includes an auxiliary rod 23, a protrusion 24, a third spring 25, an auxiliary block 26 and a cross bar 27. The auxiliary rod 23 is vertically arranged on one side of the abutting ball 22. There are several protrusions 24, and each protrusion 24 is evenly arranged at one end of the auxiliary rod 23 close to the abutting ball 22. The abutting ball 22 abuts against two adjacent protrusions 24. A vertical auxiliary groove is arranged on one side of the auxiliary rod 23. The cross section of the auxiliary groove is T-shaped. The auxiliary block 26 is arranged in the auxiliary groove, and the auxiliary block 26 is slidably connected with the auxiliary groove. The cross bar 27 is arranged between the auxiliary block 26 and the fixed box 1. One end of the cross bar 27 is connected with the fixed box 1, and the other end of the cross bar 27 is connected with the auxiliary block 26. The third spring 25 is arranged in the auxiliary groove. The third spring 25 is located above the auxiliary block 26. One end of the third spring 25 is connected with the auxiliary block 26, and the other end of the third spring 25 is connected with the inner wall of the top end of the auxiliary groove.

[0042] Preferably, in order to push the auxiliary rod 23, the moving unit is arranged above the auxiliary rod 23. The moving unit includes a moving rod 28, a wedge plate 29 and a ball 30. An arc-shaped moving groove is provided at one end of the fixed box 1 close to the auxiliary rod 23. The center of the moving groove is located on the axis of the connecting cylinder 2. The wedge plate 29 is arranged at one end of the fixed box 1. The wedge plate 29 is located above the auxiliary rod 23. The moving rod 28 is arranged between the wedge plate 29 and the connecting cylinder 2. One end of the moving rod 28 passes through the moving groove and is connected to the end face of the outer ring of the connecting cylinder 2. The other end of the moving rod 28 is connected to the wedge plate 29. The moving rod 28 is slidably connected to the moving groove. The ball 30 is arranged between the auxiliary rod 23 and the wedge plate 29. One end of the ball 30 is connected to the auxiliary rod 23. The other end of the ball 30 abuts against the wedge plate 29. The ball 30 is rotatably connected to the wedge plate 29.

[0043] Preferably, in order to grind the material, the grinding assembly includes a telescopic rod 31, an arc-shaped grinding plate 32 and a semi-circular baffle 33. The centers of the grinding plate 32 and the baffle 33 are located on the driven rod 6. The grinding plate 32 is horizontally arranged below the connecting cylinder 2. There are two baffle plates 33. The two baffle plates 33 are respectively arranged at both ends of the grinding plate 32. The two baffle plates 33 respectively abut against the end faces at both ends of the connecting cylinder 2. The grinding plate 32 abuts against the connecting cylinder 2. A plurality of discharge holes are provided on the grinding plate 32. The discharge holes are evenly arranged. A plurality of through holes are provided at one end of the connecting cylinder 2 close to the grinding plate 32. The through holes are evenly arranged. The through holes and the discharge holes are arranged in a staggered manner. There are two telescopic rods 31. The two telescopic rods 31 are respectively arranged at both ends of the grinding plate 32. One end of the telescopic rod 31 is connected to the end of the grinding plate 32 far from the connecting cylinder 2. The other end of the telescopic rod 31 is connected to the inner wall of the bottom end of the fixed box 1.

[0044] When the connecting cylinder 2 rotates here, it simultaneously drives the moving rod 28 to rotate. The moving rod 28 drives the wedge plate 29 to rotate around the axis of the connecting cylinder 2. At this time, the wedge plate 29 will drive the ball 30 to slide on the wedge plate 29. And the wedge plate 29 is not on the axis of the connecting cylinder 2. In this way, the wedge plate 29 can also push the ball 30 at the same time. The ball 30 drives the auxiliary rod 23 to move. The auxiliary rod 23 drives the protrusion 24 to move. The protrusion 24 drives the abutting ball 22 to move. The abutting ball 22 drives the communicating pipe 21 to move. The communicating pipe 21 drives the pushing ring 20 to move. This will make the first springs 12 in two adjacent crushing units in a compressed state, thereby reducing the gap between the two crushing units. At the same time, it makes the crushing unit slide on the driven rod 6, so that the blade 13 abuts against the material better. When the pushing ring 20 moves here, through the restoring force of the first spring 12, it can also drive the limiting ring 8 to move towards the motor 3 at the same time. The limiting ring 8 drives the driven rod 6 to move. The driven rod 6 drives the second magnet 10 to move towards the first magnet 9, thereby increasing the repulsive force between the second magnet 10 and the first magnet 9. Here, through the repulsive force between the first magnet 9 and the second magnet 10, the driven rod 6 can also be restored. Here, through the movement of the driven rod 6, that is, the movement of the crushing unit in the connecting cylinder 2 is realized, and the crushing effect is improved.

[0045] Here, through a number of protrusions 24 provided on the auxiliary rod 23, the abutting ball 22 reciprocates. Here, through the restoring force of the third spring 25 inside the auxiliary groove provided on the auxiliary rod 23, the ball 30 always abuts against the wedge plate 29. At the same time, through the cooperation of the auxiliary block 26 and the cross bar 27, the limiting of the auxiliary rod 23 is realized, preventing the movement of the auxiliary rod 23, so that the protrusion 24 and the abutting ball 22 abut better.

[0046] Here, the movement of the grinding plate 32 is realized through the restoring force of the telescopic rod 31, reducing the gap between the grinding plate 32 and the connecting cylinder 2, thereby improving the grinding effect. Here, through the through holes provided on the connecting cylinder 2, the material located inside the connecting cylinder 2 falls through the through holes between the grinding plate 32 and the outer ring of the connecting cylinder 2. Then, through the rotation of the connecting cylinder 2, the extrusion of the material is realized, that is, the grinding of the material is realized. And the material that meets the requirements will flow out through the discharge holes provided on the grinding plate 32, so that the material falls to the bottom end inside the fixed box 1.

[0047] Here, through the baffles 33 provided at both ends of the grinding plate 32, not only can the material be blocked, but also the limiting of the connecting cylinder 2 can be realized, making the connecting cylinder 2 rotate more stably.

[0048] Here, the linkage of multiple mechanisms is realized through the same drive source, saving costs and improving practicability.

[0050] When feeding materials is required here, first push the diversion cover 37. The diversion cover 37 drives the second feeding pipe 35 to move towards the first feeding pipe 34, so that the second feeding pipe 35 is located in the first feeding pipe 34 and abuts against the sealing plate 39. At this time, the fourth spring 36 is in a compressed state. Then push the second feeding pipe 35, so that the second feeding pipe 35 drives the sealing plate 39 to move, so that the feeding pipe is located between the sealing plate 39 and the inner wall of the first feeding pipe 34. Through the restoring force of the torsion spring at the hinge of the sealing plate 39, the limit of the second feeding pipe 35 is realized, preventing the movement of the second feeding pipe 35, thereby facilitating the addition of materials. Here, the restoring force of the torsion spring at the hinge of the sealing plate 39 is greater than the restoring force of the fourth spring 36. Through the cooperation of the first feeding pipe 34 and the second feeding pipe 35, the materials can enter the connecting pipe. Through the sealing plate 39 arranged inside the first feeding pipe 34, the connecting cylinder 2 is in a sealed state when rotating, preventing the uncut materials from falling into the fixed box 1 and improving the quality of the materials.

[0051] Compared with the prior art, the iron tailings sand making equipment realizes the crushing of materials through the cooperation of the driving unit and the crushing unit. Here, through the cooperation of the limiting unit and the rotating unit, not only can the reciprocating rotation of the connecting cylinder 2 be realized, increasing the contact between the materials and the blade 13 and improving the crushing effect, but also the operation of the grinding assembly can be realized, and the grinding of the materials can be achieved through extrusion. Here, through the vibration unit, the reciprocating movement of the crushing unit can also be realized, thereby further improving the crushing effect and working efficiency. Here, through the feeding mechanism, the sealing of the connecting cylinder 2 is set to prevent the uncut materials from falling into the fixed box 1 when the connecting cylinder 2 rotates, improving the quality. Here, through the same driving source, the linkage of multiple mechanisms is realized, saving costs and improving practicability.
