Description

Technical Field

[0001] The invention belongs to the technical field of conveying equipment, and in particular relates to a mining material conveying device driven by a permanent magnetic roller. Background Art

[0002] Conveyor belts, also known as transport belts, are composite products of rubber, fiber, metal, or plastic and fabric that carry and transport materials in belt conveyors. Conveyor belts can transport materials continuously, efficiently, and at large angles. They are safe to operate, easy to use, and easy to maintain. They are also inexpensive and can shorten transportation distances, reduce project costs, and save manpower and material resources.

[0003] Conveyor belts are mostly used in coal mines to transport crushed coal blocks to designated stockpiles. There are several problems with transporting coal blocks via conveyor belts: 1. In the process of transporting stones, dust and debris are easily entrained at the corners where the conveyor belt and the transport frame are connected. In addition, coal powder is mixed in the coal blocks during transportation. If the coal powder encounters a humid environment or humid air, it will stick to the inside of the corners where the transport frame is connected. Moreover, this bonded coal powder will gradually accumulate on the conveyor belt and the frame, affecting the transport capacity and transport effect.

[0004] 2. The existing conveyor belts are not loaded evenly during transportation, and it is difficult to ensure that every transport frame can be effectively loaded.

[0005] 3. Due to the transportation slope from low to high and the transportation vibration, coal leakage or coal blocks may fall during transportation.

[0006] Therefore, we propose a mining material conveying device driven by a permanent magnetic roller. Summary of the invention

[0009] Furthermore, it also includes a cleaning mechanism, which is installed between the two side plates. The cleaning mechanism includes a transmission rod located at the bottom of the conveyor belt, and multiple transmission rods are installed between the two side plates in a rotatable and equidistant manner. A fixed sleeve is installed on the outer surface of the transmission rod, and a knocking rod is fixedly connected to the outer surface of the fixed sleeve in sequence and equidistantly; a transmission belt is installed on the outer surface of one end of the multiple transmission rods, and a first pulley is installed on the other end of one of the transmission rods, and a first pulley is also installed on one side surface of the permanent magnet roller located at one end of the conveyor belt feed port, and a first connecting belt is installed between the two first pulleys.

DETAILED DESCRIPTION

[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention is further described in detail in conjunction with the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. The technical solutions of the present invention are described in detail below in conjunction with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0017] See also Figures 1 to 5 , this embodiment proposes a mining material conveying device driven by a permanent magnetic roller, including a belt conveyor, a cleaning mechanism and a screening mechanism; The belt conveyor is an existing device, which includes a side plate 1, a permanent magnet roller 2 and a conveyor belt 3. A permanent magnet roller 2 is rotatably installed between the two ends of the two side plates 1, and the permanent magnet roller 2 is electrically controlled and connected by an external power supply. The outer surface of the permanent magnet roller 2 is installed with a conveyor belt 3; the outer surface of the conveyor belt 3 is fixedly connected with partitions 4 at equal intervals in sequence, and the outer surface of the conveyor belt 3 is symmetrically fixedly connected with skirt plates 5, and the skirt plates 5 are fixedly connected to the partitions 4. The two side plates 1 are internally installed with limited rollers 6, and the two side plates 1 are rotatably installed with a limited rotating rod 7; the two side plates 1 are rotatably installed with a connecting rod 8 at equal intervals in sequence, and the outer surface of the connecting rod 8 is installed with a rubber roller 9.

[0018] A cleaning mechanism is installed between the two side plates 1, and the cleaning mechanism includes a transmission rod 10 located at the bottom of the conveyor belt 3. A plurality of transmission rods 10 are equidistantly rotated and installed between the two side plates 1. A fixed sleeve 11 is installed on the outer surface of the transmission rod 10, and a plurality of knocking rods 12 are fixedly connected to the outer surface of the fixed sleeve 11 in sequence and equidistantly. A transmission belt 13 is installed on the outer surface of one end of the plurality of transmission rods 10, and a first pulley 14 is installed on the other end of one of the transmission rods 10. A first pulley 14 is also installed on one side surface of the permanent magnetic roller 2 located at one end of the feed port of the conveyor belt 3, and a first connecting belt 15 is installed between the two first pulleys 14. When the permanent magnet drum 2 rotates, it drives the first pulley 14 to rotate. The rotation of the first pulley 14 drives the transmission rod 10 to rotate through the first connecting belt 15. The rotation of the transmission rod 10 drives the fixed sleeve 11 and the knocking rod 12 to rotate. The knocking rod 12 rotates to knock the conveyor belt 3, knocking the coal powder stuck on the conveyor belt 3 off, thereby solving the problem of coal powder sticking to the conveyor belt 3.

[0019] The screening mechanism includes a screening drum 16, which is located above one end of the feed port of the conveyor belt 3 and fixedly connected to the top surface of the side plate 1. A feed port 17 is symmetrically provided on the outer surface of the top of the screening drum 16. A driving rod 18 is rotatably installed at the center of the inner part of the screening drum 16. A spiral blade 19 is symmetrically fixedly connected to the outer surface of the driving rod 18. The feed port 17 corresponds to the position of the spiral blade 19, so that the coal material entering through the feed port 17 enters the spiral blade 19. A second pulley 23 is installed on one side surface of the screening drum 16, and the second pulley 23 is fixedly connected to the driving rod 18. A second pulley 23 is also installed on the other side surface of the permanent magnet drum 2 located at one end of the feed port of the conveyor belt 3, and a second connecting belt 24 is installed between the two second pulleys 23. The screening drum 16 is provided with a screening hole 20 on the outer surface of the bottom end at the spiral blade 19, and a guide pipe 22 is symmetrically fixedly connected to the bottom surface of the screening drum 16 at the screening hole 20, and a discharge port 21 is provided on the outer surface of the bottom end at the center of the screening drum 16, and the discharge port 21 is located between the two guide pipes 22, and the discharge port 21 is used for unloading coal blocks; the guide pipe 22 is extended in the direction of the conveyor belt 3, and the guide pipe 22 is used for unloading coal powder.

[0020] The coal material is delivered to the screening drum 16 through the feed port 17, and then, as the permanent magnetic drum 2 rotates, the driving rod 18 is driven to rotate through the cooperation of the second pulley 23 and the second connecting belt 24, and the driving rod 18 rotates to drive the spiral blade 19 to rotate, and the spiral blade 19 rotates to drive the coal material to move toward the center of the screening drum 16. While moving inside the screening drum 16, the coal material passes through the screening hole 20 to screen out the small coal powder particles and guides them to the conveyor belt 3 through the guide pipe 22, while the large coal blocks pass through the discharge port 21 and directly fall onto the conveyor belt 3. Since the guide pipe 22 extends forward, the large coal blocks fall onto the conveyor belt 3 first, and then the small coal powder particles are placed on the coal blocks on the conveyor belt 3.

[0021] The working principle of a mining material conveying device driven by a permanent magnetic roller provided in this embodiment is as follows: When the device is needed, firstly, the coal material is delivered into the screening drum 16 through the feeding port 17, and then, as the permanent magnetic drum 2 rotates, the driving rod 18 is driven to rotate through the cooperation of the second pulley 23 and the second connecting belt 24, and the driving rod 18 rotates to drive the spiral blade 19 to rotate, and the spiral blade 19 rotates to drive the coal material to move toward the center of the screening drum 16. While the coal material moves inside the screening drum 16, the coal material passes through the screening hole 20 to screen out the coal powder in the coal and guides it to the conveyor belt 3 through the guide pipe 22, while the coal blocks pass through the discharge port 21 and fall onto the conveyor belt 3; and because the guide pipe 22 extends forward, the large coal blocks fall onto the conveyor belt 3 first, and then the small coal powder particles are placed on the coal blocks on the conveyor belt 3. The coal powder particles can fill the gaps between the coal blocks, making the coal on the conveyor belt 3 more compact and reducing the space waste caused by the gaps. When coal powder and coal blocks are transported together, the coal powder will fill the gaps between the coal blocks. A certain compression and adhesion force will be generated between the coal powder particles and between the coal powder and the coal blocks. Under the action of this force, the coal powder can firmly adhere to the surface and gaps of the coal blocks, forming a stable covering layer, which improves the overall density and stability, and reduces the flying of coal dust.

[0022] At the same time, when the permanent magnet drum 2 rotates, it drives the first pulley 14 to rotate. The rotation of the first pulley 14 drives the transmission rod 10 to rotate through the first connecting belt 15. The rotation of the transmission rod 10 drives the fixed sleeve 11 and the knocking rod 12 to rotate. The knocking rod 12 rotates to knock the conveyor belt 3, knocking the coal powder stuck on the conveyor belt 3 off, thereby solving the problem of coal powder sticking.

It cannot be determined that the specific embodiments of the present invention are limited to this.
