[0002] A crusher is a mechanical device for crushing stones. Crushers mainly crush large stones into smaller particles by means of extrusion, impact, grinding, etc. Then, the crushed stones are conveyed to a designated position through a crawler conveyor.

[0003] There are often metal impurities in the crushed stones. For the metal impurities in the crushed stones, it is necessary to separate and collect them to prevent the metal impurities from being mixed in the crushed stone pile, so that there are sundries in the crushed stones, reducing the subsequent utilization effect of the crushed stones. Summary of the Utility Model

[0004] In order to separate and collect the metal impurities in the crushed stones, the present application provides a magnetic impurity removal system for crushers.

[0005] A magnetic impurity removal system for crushers provided by the present application adopts the following technical solutions:

[0006] A magnetic impurity removal system for crushers includes a frame, a conveyor belt, and an impurity removal mechanism. The conveyor belt is drivingly connected to the frame. The starting end of the conveyor belt is located on one side of the discharge port of the crusher. The impurity removal mechanism is used to remove impurities from the crushed stones. The impurity removal mechanism includes a magnetic component and a conveyor belt. The magnetic component is fixedly connected to the frame. The magnetic component is located above the conveyor belt. The conveyor belt is drivingly connected to the frame. The driving direction of the conveyor belt is arranged in a staggered manner with the conveying direction of the conveyor belt. The conveyor belt is wound around the magnetic component.

[0007] By adopting the above technical solutions, the stones crushed by the crusher are conveyed through the conveyor belt. When the crushed stones are conveyed to the lower end of the magnetic component, the metal impurities will be adsorbed on the conveyor belt due to the magnetic force of the magnetic component, so as to achieve the purpose of removing the metal impurities in the crushed stone pile. When the metal impurities on the conveyor belt are conveyed towards the side away from the magnetic component, the magnetic force received by the metal impurities weakens and they fall off the conveyor belt within a specified range, facilitating the collection of the metal impurities.

[0008] Preferably, a scraping rod is fixedly connected to the frame. The scraping rod is located on one side of the end of the driving direction of the conveyor belt. The scraping rod abuts against the conveyor belt.

[0009] By adopting the above technical solution, by providing a scraping rod, when the metal impurities adsorbed on the conveyor belt are conveyed to the position of the scraping rod, the metal impurities on the conveyor belt are scraped off by the scraping rod, so that the metal impurities fall below the conveyor belt, which is convenient for collecting the metal impurities and can reduce the possibility that some metal impurities with strong magnetism still adhere to the conveyor belt.

[0010] Preferably, a collection box for collecting metal impurities is provided on the frame, a guide plate is provided on the frame, the guide plate is located below the scraping rod, and one end of the guide plate abuts against the collection box.

[0011] By adopting the above technical solution, after the scraping rod scrapes off the metal impurities on the conveyor belt, the metal impurities fall on the guide plate, and the guide plate guides the metal impurities, so that the metal impurities fall into the collection box, which is convenient for collecting the metal impurities and reduces the possibility that the metal impurities falling from the conveyor belt scatter.

[0012] Preferably, a baffle is fixedly connected to the side of the scraping rod away from the conveyor belt, and the baffle is located above the guide plate.

[0013] By adopting the above technical solution, it reduces the possibility that the scraped metal impurities or the metal impurities with weak magnetism fly out due to inertia when the conveyor belt runs too fast, which plays a protective role for the staff around the equipment; and the baffle is located above the guide plate. When the metal impurities fly to the baffle, the metal impurities fall on the guide plate along the side of the baffle, which is convenient for collecting the metal impurities.

[0014] Preferably, a limiting rod is slidably connected to the frame along the direction perpendicular to the transmission direction of the conveyor belt. The limiting rod is located between the conveyor belt and the transmission belt, and there is a gap between the limiting rod and the transmission belt. The stone materials are conveyed through the gap between the limiting rod and the transmission belt.

[0015] By adopting the above technical solution, the setting of the limiting rod limits the height of the crushed stones on the conveyor belt and makes the crushed stones spread out on the conveyor belt, reducing the possibility that the crushed stones on the transmission belt accumulate and prevent the metal impurities in the crushed stone pile from being adsorbed, thereby improving the impurity removal efficiency of the crushed stone pile.

[0016] Preferably, a vibrator is provided on the frame, the conveyor belt is wound around the vibrator, the vibrator is located below the magnetic attracting member, and the limiting rod is located on the side of the vibrator close to the main body of the crusher.

[0017] By adopting the above technical solution, when the crushed stone pile is conveyed below the magnetic attracting member, the vibrator vibrates the conveyor belt at this section, reducing the possibility that smaller metal impurities accumulate under the crushed stones and cannot be sucked out, so as to improve the impurity removal efficiency of the crushed stone pile.

[0018] Preferably, the distances from both ends in the width direction of the conveyor belt to the middle section in the width direction of the conveyor belt gradually become closer to the vibrator.

[0019] By adopting the above technical solution, the movement of crushed stones caused by vibration or the process of adsorbing metals is reduced, and the possibility of crushed stones falling out from both sides of the conveyor belt is minimized.

[0020] The technical effects of the present utility model are mainly reflected in the following aspects:

[0021] 1. By setting the impurity removal mechanism in the present utility model, the stones crushed by the crusher are conveyed through the conveyor belt. When the crushed stones are conveyed to the lower end of the magnetic attracting member, the metal impurities will be adsorbed on the conveyor belt due to the magnetic force of the magnetic attracting member, thereby achieving the purpose of removing metal impurities in the crushed stone pile; when the metal impurities on the conveyor belt are conveyed towards the side away from the magnetic attracting member, the magnetic force received by the metal impurities weakens and they fall off the conveyor belt within a specified range, facilitating the collection of metal impurities.

[0022] 2. By setting the scraping rod in the present utility model, when the metal impurities adsorbed on the conveyor belt are conveyed to the scraping rod, the metal impurities on the conveyor belt are scraped by the scraping rod, so that the metal impurities fall below the conveyor belt, facilitating the collection of metal impurities, and reducing the possibility that some metal impurities with stronger magnetism still adhere to the conveyor belt.

[0023] 3. By setting the limiting rod in the present utility model, the limiting rod limits the height of the crushed stones on the conveyor belt and makes the crushed stones spread flat on the conveyor belt, reducing the possibility that the accumulation of crushed stones on the conveyor belt causes the metal impurities in the crushed stone pile to be unable to be adsorbed, thereby improving the impurity removal efficiency of the crushed stone pile.

[0031] The following further elaborates on this application in conjunction with the Figures 1-6 accompanying drawings to make the technical solutions of this application easier to understand and master.

[0032] An embodiment of this application discloses a magnetic impurity removal system for a crusher.

[0033] Referring to Figures 1-6 , a magnetic impurity removal system for a crusher in this embodiment includes a frame 1, a conveyor belt 11, and an impurity removal mechanism 2. The conveyor belt 11 is drivingly connected to the frame 1. The starting end of the conveyor belt 11 is located on one side of the discharge port of the crusher 3. The impurity removal mechanism 2 is used to remove impurities from the crushed stones. The impurity removal mechanism 2 includes a magnetic component 21 and a transmission belt 22. The magnetic component 21 is fixedly connected to the frame 1. The magnetic component 21 is located above the conveyor belt 11. The transmission belt 22 is drivingly connected to the frame 1. The driving direction of the transmission belt 22 is arranged in an interleaved manner with the conveying direction of the conveyor belt 11. One side surface of the transmission belt 22 opposite to the interleaved part with the conveyor belt 11 is arranged in parallel. The transmission belt 22 is wound around the magnetic component 21. The magnetic component 21 is a rare earth permanent magnet separator, a ferrite permanent magnet separator, or an electromagnetic separator.

[0034] Referring to Figures 1-5 , a limit rod 12 is slidably connected to the frame 1 along a direction perpendicular to the driving direction of the conveyor belt 11. A hydraulic cylinder is fixedly connected to the frame 1. One end of the piston rod of the hydraulic cylinder is fixedly connected to the limit rod 12 and drives the sliding of the limit rod 12. The limit rod 12 is located between the conveyor belt 11 and the transmission belt 22. There is a spacing between the limit rod 12 and the transmission belt 22. The stones are conveyed through the spacing between the limit rod 12 and the transmission belt 22.

[0035] Referring to Figure 3 and Figure 5, a vibrator 13 is fixedly connected to the frame 1, a conveyor belt 11 is wound around the vibrator 13, the vibrator 13 is located below the magnetic part 21, the vibrator 13 is composed of a contact plate, a motor and a cam. The contact plate is slidably connected to the frame 1 in a direction perpendicular to the driving direction of the conveyor belt 11. One side of the contact plate abuts against the conveyor belt 11. The motor is fixedly connected to the frame 1, the cam is fixedly connected to the output shaft of the motor, and the circumferential surface of the cam always abuts against the side surface of the contact plate away from the conveyor belt 11. When the motor drives the cam to rotate, the contact plate slides repeatedly in a direction perpendicular to the conveyor belt 11 and abuts against this section of the conveyor section, so that this section of the conveyor belt 11 vibrates. The limiting rod 12 is located on one side of the vibrator 13 close to the main body of the crusher 3.

[0036] Refer to Figure 2- Figure 6 , the setting of the limiting rod 12 limits the height of the crushed stones on the conveyor belt 11 and makes the crushed stones spread flat on the conveyor belt 11, reducing the possibility of crushed stones piling up on the conveyor belt 22 and resulting in the inability to adsorb the metal impurities in the crushed stone pile, thereby improving the impurity removal efficiency of the crushed stone pile. When the crushed stone pile is conveyed below the magnetic part 21, the vibrator 13 vibrates this section of the conveyor belt 11, reducing the possibility that smaller metal impurities accumulate under the crushed stones and cannot be sucked out, so as to improve the impurity removal efficiency of the crushed stone pile.

[0037] Refer to Figures 1-5 , the distances from both ends in the width direction of the conveyor belt 11 to the middle section in the width direction of the conveyor belt 11 gradually become closer to the vibrator 13. A connecting rod is fixedly connected to the frame 1. The distances from both ends in the length direction of the connecting rod to the middle section of the connecting rod gradually become closer to the frame 1. A plurality of rollers 111 are rotatably connected to the connecting rod, and the plurality of rollers 111 are evenly distributed along the axis direction of the connecting rod. The conveyor belt 11 abuts against the rollers 111, reducing the possibility of the crushed stones moving due to vibration or the process of adsorbing metal and falling out from both sides of the conveyor belt 11.

[0038] Refer to 1- Figure 6 , a scraping rod 14 is fixedly connected to the frame 1. The scraping rod 14 is located on one side of the end of the conveyor belt 22 in the driving direction. The scraping rod 14 abuts against the conveyor belt 22. A guiding plate 15 is fixedly connected to the frame 1. The guiding plate 15 is located below the scraping rod 14. One end of the guiding plate 15 abuts against the conveyor belt 11. A collecting frame 16 for collecting metal impurities is fixedly connected to the frame 1. The end of the guiding plate 15 away from the conveyor belt 11 abuts against the collecting frame 16. A baffle 17 is fixedly connected to the side of the scraping rod 14 away from the conveyor belt 11, and the baffle 17 is located above the guiding plate 15.

[0039] Refer to 1- Figure 6, by setting the scraping rod 14, when the metal impurities adsorbed on the conveyor belt 22 are transported to the position of the scraping rod 14, the metal impurities on the conveyor belt 22 are scraped by the scraping rod 14, so that the metal impurities fall below the conveyor belt 22, and the possibility that some metal impurities with stronger magnetism still adhere to the conveyor belt 22 can be reduced. After the scraping rod 14 scrapes the metal impurities on the conveyor belt 22, the metal impurities fall on the guide plate 15, and the guide plate 15 guides the metal impurities, so that the metal impurities fall into the collection box 16, which is convenient for collecting the metal impurities and reduces the possibility that the metal impurities falling from the conveyor belt 22 scatter and float. The setting of the baffle 17 reduces the possibility that the scraped metal impurities or the metal impurities with weak magnetism fly out due to inertia when the conveyor belt 22 runs too fast, which plays a protective role for the staff around the equipment; and the baffle 17 is located above the guide plate 15. When the metal impurities fly to the baffle 17, the metal impurities fall on the guide plate 15 along the side surface of the baffle 17, which is convenient for collecting the metal impurities.

[0040] Refer to 1- Figure 6 , the stone materials crushed by the crusher 3 are transported through the conveyor belt 11. When the crushed stones are transported to the lower end of the magnetic attracting member 21, the metal impurities will be adsorbed on the conveyor belt 22 due to the magnetic force of the magnetic attracting member 21, so as to achieve the purpose of removing the metal impurities in the crushed stone pile; when the metal impurities on the conveyor belt 22 are transported to the side away from the magnetic attracting member 21, the magnetic force received by the metal impurities weakens and the metal impurities fall off the conveyor belt 22 within the specified range, which is convenient for collecting the metal impurities and has achieved the purpose of separating and collecting the metal impurities in the crushed stones.

[0041] Of course, the above are only typical examples of this application. In addition, this application can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by this application.
