Description

Technical Field

[0001] The utility model relates to the technical field of fabrics, in particular to a multi-point automatic fabric distributing device for a mine belt conveyor. Background Art

[0002] In the fields of mine exploitation and mineral processing, belt conveyors are one of the indispensable important devices for efficiently transporting a large amount of ores or other bulk materials. However, in the existing belt conveyor systems, especially in environments where multi-point automatic fabric distribution is required, a series of technical challenges are often faced. Among them, the most prominent problems are frequent failures and low efficiency during the fabric distribution process. In traditional multi-point fabric distribution systems, a fabric distribution trolley is used for fabric distribution, that is, the trolley moves on the belt for fabric distribution. When the head of the belt conveyor needs to discharge materials, the flap is closed. However, the trolley is prone to wear, and the uniform distribution of materials often depends on manual intervention or simple mechanical devices. This method not only increases the workload of operators, but also due to the inability to adjust the fabric distribution position and quantity in real time, the phenomenon of material accumulation or uneven distribution often occurs. These problems not only reduce production efficiency, but also may trigger a series of chain reactions such as increased conveyor belt wear and rising equipment failure rates, seriously affecting the normal operation of mine production. In addition, the materials often contain iron impurities. If the iron impurities in the ores are not removed, downstream equipment will be damaged. Content of the Utility Model

[0003] The purpose of the utility model is to provide a multi-point automatic fabric distributing device for a mine belt conveyor, which realizes the precise placement and efficient transportation of materials, improves the overall efficiency and safety of mine operations, and at the same time sets up an iron removal device that is easy to clean to remove iron parts in the materials, so as to protect downstream equipment from damage, and solves the problems in the prior art.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A multi-point automatic fabric distributing device for a mine belt conveyor includes a feeding belt conveyor, the feeding belt conveyor is arranged at a fixed position, a track is arranged below the feeding belt conveyor, a moving belt conveyor is arranged on the track, a bin is arranged directly below the track, an iron removal device is arranged above the moving belt conveyor, the iron removal device includes a hanging rack, an iron remover and a receiving box, the iron remover is installed above the moving belt conveyor through the hanging rack, the receiving box is located at the bottom side of the iron remover, a scale is installed on the side edge of the track, and the scale cooperates with a reading probe installed on the moving belt conveyor.

[0006] Preferably, the moving belt conveyor includes a first motor, a second motor, pulleys, a belt body, a connecting shaft, a transmission belt and a baffle. Guard plates are arranged on both sides of the belt body, a baffle is arranged above the guard plates, and a second motor is fixed on one side of the guard plates, and the second motor is connected to a transmission roller.

[0007] Preferably, several pairs of pulleys are arranged under the guard plate, and the pulleys opposite to each other on both sides of the belt body are connected by a connecting shaft, a first motor is installed in the middle of one of the connecting shafts, and the top of the first motor is connected to the guard plates on both sides through a fixing plate.

[0008] Preferably, the reading probe is installed on the outer side surface of one side guard plate, and the collecting end of the reading probe faces downward and directly faces the scale.

[0009] Preferably, an iron remover is connected to the horizontal bar above the hanger through a rope, and the iron remover is located directly above the belt body. One end of the receiving box is pivotally connected to one of the support rods of the hanger, and a proximity switch is correspondingly arranged on the other support rod of the hanger. The other end of the receiving box is provided with a sensing surface that cooperates with the proximity switch.

[0010] Preferably, the silos are provided in a plurality and are distributed linearly, and their extending direction is the same as the conveying direction of the mobile belt conveyor.

[0011] Preferably, two level meters are provided at the upper position of the inner wall of each silo, and the level meters are arranged opposite to each other.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. In the utility model, the mobile belt conveyor continues to convey materials so that the materials fall into the current silo. The production coordination control system determines the material level of the current silo by detecting the value of the material level meter and decides whether to continue unloading or stop unloading. After stopping unloading, the production coordination control system detects the material levels of the silos in front and behind the mobile belt conveyor. When a low-level silo is detected, the mobile belt conveyor is directed to the nearest low-level silo. When it is detected that there are no low-level silos in the front and rear, an alarm is sounded and unloading is stopped. The equipment failure rate is lower, the system maintenance workload is reduced, and the continuity and efficiency of production are guaranteed.

[0014] 2. The iron remover in the utility model adopts an electromagnet, which generates magnetic force when energized and disappears when the electromagnetic force is turned off. The iron debris in the material passing below is adsorbed by the iron remover to protect the downstream equipment. When there are many iron pieces adsorbed on the iron remover, the receiving box is rotated from one side of the belt body to the bottom of the iron remover. At this time, the proximity switch and the sensing surface are closed, so that the circuit of the iron remover is cut off, the magnetic force disappears, and the iron pieces fall from the iron remover into the receiving box. Then the receiving box is reset, the proximity switch is separated from the sensing surface, the circuit is reconnected, and the iron remover restores its magnetic force to continue to adsorb impurities, thereby achieving convenient cleaning.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0021] In order to solve the problems in the prior art that production suspension and maintenance are easily caused by equipment wear and ore jamming during cloth feeding, and the miscellaneous iron in the material is likely to damage the downstream equipment, the following technical solutions are given. Please refer to Figures 1-4 ;

[0022] A multi-point automatic cloth feeding device for a mine belt conveyor, including a feeding belt conveyor 1, characterized in that a track 3 is arranged below the feeding belt conveyor 1, a mobile belt conveyor 2 is arranged on the track 3, a bunker 6 is arranged directly below the track 3, an iron removal device 4 is arranged above the mobile belt conveyor 2, and a scale 7 is arranged on the side of the track 3, and the extending direction of the scale is the same as the extending direction of the track 3.

[0023] The mobile belt conveyor 2 includes a first motor 21, a second motor 22, a pulley 23, a belt body 24, a connecting shaft 25, a transmission belt 26 and a baffle 27. Guard plates 28 are arranged on both sides of the belt body 24, and a baffle 27 is arranged above the guard plates 28. The baffle 27 is used to prevent the material from leaking out from both sides of the belt body 24 and the end for receiving the material; one side of the guard plate 28 is fixed with a second motor 22, the second motor 22 is connected to the driving roller, and the second motor 22 drives the driving roller to continuously convey the material on the belt body 24;

[0024] Below the guard plate 28, a number of pairs of pulleys 23 are provided. The pulleys 23 on opposite sides of both sides of the belt body 24 are connected by a connecting shaft 25. The adjacent two connecting shafts 25 are connected by a transmission belt 26. In the middle of one of the connecting shafts 25, a first motor 21 is installed. The first motor 21 is a double-output shaft motor. The top of the first motor 21 is connected to the guard plates 28 on both sides through a fixing plate. The first motor 21 enables the pulley 23 to rotate forward or backward, so that the mobile belt conveyor 2 moves back and forth along the track 3, realizing the function of moving the cloth.

[0025] The iron removal device 4 includes a hanging rack 41, an iron remover 42, a receiving box 43 and a proximity switch 44. The two support rods of the hanging rack 41 are respectively located on both sides of the mobile belt conveyor 2. An iron remover 42 is connected by a rope on the cross bar above the hanging rack 41. The iron remover 42 is located directly above the belt body 24. The iron remover 42 uses an electromagnet. The iron remover 42 is connected to the power supply. When the iron remover 42 is energized, it generates magnetic force, and when the power is cut off, the magnetic force disappears. The iron parts and sundries in the materials passing under it are adsorbed by the iron remover 42 to protect the downstream equipment.

[0026] Below the iron remover 42, there is a receiving box 43. One end of the receiving box 43 is pivotally connected to one of the support rods of the hanging rack 41. The other end of the receiving box 43 is provided with a first mounting plate 45. A second mounting plate 46 is correspondingly arranged on the other support rod of the hanging rack 41. A proximity switch 44 is arranged on the second mounting plate 46. An induction surface matching the proximity switch 44 is arranged on the first mounting plate 45. The proximity switch 44 is electrically connected to the power supply of the iron remover 42.

[0027] Specifically, when there are more iron parts adsorbed on the iron remover 42, rotate the receiving box 43 so that it rotates from one side of the belt body 24 to directly below the iron remover 42. At this time, the proximity switch 44 is closed with the induction surface, cutting off the circuit of the iron remover 42, and the magnetic force disappears. The iron parts fall from the iron remover 42 into the receiving box 43. Then reset the receiving box 43. The proximity switch 44 is separated from the induction surface, reconnecting the circuit, and the iron remover 42 resumes magnetic force to continue adsorbing impurities. The staff cleans the iron parts in the receiving box 43.

[0028] The side of the scale 7 with scale values faces directly upward. One side of the scale 7 is installed at the side edge position of the track 3. A reading probe 8 is installed on the outer side surface of one of the guard plates 28. The acquisition end of the reading probe 8 faces downward and is directly opposite to the scale 7.

[0029] A number of bins 6 are provided and are linearly distributed. Their extending direction is the same as the conveying direction of the mobile belt conveyor 2; at a position slightly above the inner side wall of each bin 6, two level gauges 5 are provided and are arranged oppositely. The level gauges 5 are used to detect the material level in the bin 6, and their average value is fed back to the system. The maximum value of the level gauges 5 is usually set to 70%-80% of the volume of the bin 6.

[0030] By detecting the value of the level gauge 5 and coordinating with the reading of the scale on the track 3, the positioning, direction, and whether to unload of the mobile belt conveyor 2 are determined, so as to realize automatic batching.

[0031] Working principle: The materials on the feeding belt conveyor 1 are transported and fall onto the belt body 24, so that the materials continue to be transported and fall into the current bin 6. The production coordination control system judges the level of the current bin 6 by detecting the value of the level gauge 5. When the detected value is less than the maximum limit level, unloading continues; when the detected value is equal to or greater than the maximum limit level, unloading stops; after unloading stops, the production coordination control system detects the level of the bin 6 in front of the mobile belt conveyor 2. When there is a bin 6 with a low level in front, the first motor 21 is driven to make the pulley 23 rotate forward, driving the mobile belt conveyor 2 to reach the nearest bin 6 with a low level; when the bin 6 in front is full, the level of the bin 6 behind the mobile belt conveyor 2 is detected. When there is a bin 6 with a low level behind, the first motor 21 is started to drive the mobile belt conveyor 2 to move backward and reach the nearest bin 6 with a low level. When it is detected that there is no bin 6 with a low level in both the front and the back, the production coordination control system issues an alarm and stops unloading.
