Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, and in particular to an automatic ore discharge and iron removal device for mining operations. Background Technology

[0002] In mining operations, the screening of iron ore or magnetic minerals is a crucial step. Currently, most mining operations use iron separators to screen the mined ore. These separators use magnetic rings to adsorb iron ore or magnetic minerals onto the rings.

[0003] However, the distance between most iron removers and the conveyor belt is fixed. Due to the complex and variable environment of ore mining and the significant differences in ore characteristics between different mining areas, it is impossible to flexibly adjust the distance between the magnetic ring and the conveyor belt according to the ore properties, particle size, and magnetic strength. This results in unstable iron removal effect when processing different ores, and the problem of excessive iron ore or magnetic mineral residue may occur. Therefore, it is necessary to improve the existing technology to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automatic ore discharge and iron removal device for mining operations.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic ore discharge and iron removal device for mining includes a frame and a fixed frame. A conveyor belt is installed inside the frame, and the frame passes through the fixed frame. A sliding plate is installed inside the fixed frame. First grooves are formed on both sides of the fixed frame, allowing the sliding plate to move along the grooves. A lead screw is rotatably connected inside the fixed frame, passing through the sliding plate and threadedly connected to it. A motor is fixedly connected to the top of the fixed frame, with one end of the motor's output shaft passing through the fixed frame and fixed to the lead screw. A rotating motor is fixedly connected to the top of the sliding plate, with one end of the rotating motor's output shaft passing through the sliding plate and fixed to a rotating shaft via a coupling. A support frame is fixedly connected to the outside of the rotating shaft. A housing is fixedly connected to the bottom of the support frame at each of the four outlet positions. A magnetic ring is fixedly connected to the outside of the housing at the bottom position. A pushing assembly is provided outside the magnetic ring. Discharge hoppers are fixedly connected to the outer walls of both sides of the frame. A receiving assembly for collecting the discharged ore is provided inside the fixed frame.

[0007] As a further embodiment of this utility model, the pushing assembly includes a spacer, which is sleeved on the outside of the magnetic ring. An electric push rod is fixedly connected inside the housing, and one end of the telescopic part of the electric push rod is fixed to the spacer.

[0008] As a further embodiment of this utility model, the receiving component includes a receiving tray, and a second sliding groove is provided on the inner walls of both sides of the fixing frame near the bottom. The receiving tray is disposed inside the fixing frame and is slidably connected to the second sliding groove. The receiving tray is located below the discharge hopper.

[0009] As a further improvement of this utility model, the bottom of the receiving tray is fixedly connected to four corners with casters.

[0010] As a further embodiment of this utility model, a turntable is fixedly connected to the bottom end of the rotating shaft, and multiple connecting blocks are fixedly connected to the outer circumference of the turntable, with each of the multiple connecting blocks being fixed to multiple magnetic rings.

[0011] As a further embodiment of this utility model, a guide rod is fixedly connected inside the fixing frame, and the guide rod passes through the sliding plate.

[0012] As a further improvement of this utility model, handles are fixedly connected to both sides of the receiving tray.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By using the sliding plate and the lead screw in combination, the rotation of the lead screw will cause the sliding plate to move up or down along the first chute, thereby driving the magnetic ring to move and changing the distance between the magnetic ring and the conveyor belt. This allows for better adsorption and removal of iron ore or magnetic minerals, improving the screening effect of iron impurities or magnetic minerals.

[0015] 2. By setting up the pushing component, after the magnetic ring adsorbs iron impurities or magnetic minerals, the magnetic ring is rotated to the top of the discharge hopper, and then the pushing component pushes the iron impurities or magnetic minerals off, thereby facilitating the separation of the adsorbed iron impurities or magnetic minerals from the magnetic ring and improving the convenience of using the iron remover.

[0016] 3. Through the setting of the receiving component, iron impurities or magnetic minerals entering the discharge hopper will fall into the receiving tray, thereby collecting the iron impurities or magnetic minerals in a unified manner, making it convenient for staff to collect the discharged iron impurities or magnetic minerals.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-4An automatic ore discharge and iron removal device for mining includes a frame 1 and a fixed frame 5. A conveyor belt 2 is installed inside the frame 1, passing through the fixed frame 5. A sliding plate 6 is installed inside the fixed frame 5. First grooves 7 are formed on both sides of the fixed frame 5, allowing the sliding plate 6 to move along the grooves 7. A lead screw 11 is rotatably connected inside the fixed frame 5, passing through the sliding plate 6 and threadedly connected to it. A motor is bolted to the top of the fixed frame 5, with one end of the motor's output shaft passing through the fixed frame 5 and fixed to the lead screw 11. A rotating motor is bolted to the top of the sliding plate 6, with one end of the rotating motor's output shaft passing through the sliding plate 6 and fixed to a rotating shaft 12 via a coupling. A support frame 13 is bolted to the outside of the rotating shaft 12. A housing 4 is bolted to the bottom of the support frame 13 at each of its four ends. A magnetic ring 14 is bonded to the bottom of the outer side. A pushing component is provided on the outer side of the magnetic ring 14. The two outer walls of the frame 1 are fixed with discharge hoppers 9 by bolts. The fixed frame 5 is provided with a receiving component to collect the discharged ore. When the motor is started, the motor will drive the lead screw 11 to rotate. The lead screw 11 will drive the slide plate 6 to move downward along the first slide groove 7 through the thread engagement between the lead screw 11 and the slide plate 6. The slide plate 6 will drive the rotating shaft 12 to move downward. The rotating shaft 12 will drive the support frame 13 to move downward. The support frame 13 will drive the shell 4 to move downward. The shell 4 will drive the magnetic ring 14 to move downward. By changing the distance between the magnetic ring 14 and the conveyor belt 2, the magnetic ring 14 is moved to a suitable height. Then the motor is turned off, so that the iron ore or magnetic minerals can be better adsorbed and removed, and the screening effect of iron impurities or magnetic minerals can be improved.

[0024] In this invention, the feeding assembly includes a partition 3, which is sleeved on the outside of the magnetic ring 14. An electric push rod 19 is fixed inside the housing 4 by bolts. One end of the telescopic part of the electric push rod 19 is fixed to the partition 3. The ore is conveyed by the conveyor belt 2. During the conveying process, the magnetic ring 14 will adsorb iron ore or magnetic minerals in the ore and adsorb them onto the partition 3. Then, the rotating motor is started, which will drive the rotating shaft 12 to rotate. The rotating shaft 12 will drive the support frame 13 to rotate, thereby rotating the magnetic ring 14 that adsorbs the ore to the top of the discharge hopper 9. Another magnetic ring 14 is rotated to the top of the conveyor belt 2 to continue adsorbing iron ore or magnetic minerals. Then, the electric push rod 19 is started, which will push the partition 3 to move downward, thereby pushing the adsorbed iron ore or magnetic minerals to move, so that the magnetic ring 14 no longer adsorbs the iron ore or magnetic minerals, and the iron ore or magnetic minerals fall into the discharge hopper 9.

[0025] Specifically, the receiving assembly includes a receiving tray 15. Second chutes 10 are provided on the inner walls of both sides of the fixing frame 5 near the bottom. The receiving tray 15 is installed inside the fixing frame 5 and is slidably connected to the second chutes 10. The receiving tray 15 is located below the discharge hopper 9. Iron ore or magnetic minerals falling into the discharge hopper 9 will fall into the receiving tray 15, thus allowing the receiving tray 15 to collect the iron ore or magnetic minerals uniformly. Universal wheels 16 are bolted to the four corners of the bottom of the receiving tray 15. To facilitate the movement of the receiving tray 15, making it easier for workers to pull the receiving tray 15, the bottom end of the rotating shaft 12 is fixed with a turntable 18 by bolts. Multiple connecting blocks 17 are welded to the outer circumference of the turntable 18. The multiple connecting blocks 17 are fixed to multiple magnetic rings 14 respectively. The connecting blocks 17 connect the magnetic rings 14 to the turntable 18, so that the magnetic rings 14 can be stably installed. A guide rod 8 is fixed inside the fixing frame 5 by bolts, and the guide rod 8 passes through the slide plate 6. Handles are fixed on both sides of the receiving tray 15 by bolts.

[0026] Working principle: When needed, the motor is started, which drives the lead screw 11 to rotate. The lead screw 11, through threaded engagement with the slide plate 6, causes the slide plate 6 to move downwards along the first slide groove 7. The slide plate 6 then drives the rotating shaft 12 downwards, which in turn drives the support frame 13 downwards. The support frame 13 then drives the housing 4 downwards, which in turn drives the magnetic ring 14 downwards, changing the distance between the magnetic ring 14 and the conveyor belt 2. After the magnetic ring 14 is moved to a suitable height, the motor is turned off. This allows for better adsorption and removal of iron ore or magnetic minerals, improving the screening effect of iron impurities or magnetic minerals. Subsequently, the ore is conveyed via the conveyor belt 2. During the conveying process, the magnetic ring 14... The process involves adsorbing iron ore or magnetic minerals from the ore onto the partition 3. Then, a rotating motor is activated, driving the rotating shaft 12 to rotate, which in turn drives the support frame 13. This rotates the magnetic ring 14 that adsorbs the ore directly above the discharge hopper 9, and another magnetic ring 14 above the conveyor belt 2 to continue adsorbing iron ore or magnetic minerals. Then, an electric push rod 19 is activated, pushing the partition 3 downwards, thus moving the adsorbed iron ore or magnetic minerals. This causes the magnetic ring 14 to stop adsorbing the iron ore or magnetic minerals, allowing them to fall into the discharge hopper 9 and be collected in the receiving tray 15.

[0027] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
