Description

Technical Field

[0001] This utility model relates to the field of coal mine conveyor technology, specifically a coal mine conveyor with dust reduction function. Background Technology

[0002] Coal mine conveyors are an indispensable piece of equipment in coal mine production. They are mainly used in the mining, production, transportation and processing of coal. The transmission drum is driven by an electric motor, which causes the belt to move. The material is placed on the belt and is carried along a predetermined path as the belt moves.

[0003] Coal mine conveyors with dust suppression functions use spray dust suppression components installed on both sides above the conveyor belt. Water is pumped to the spray head to spray mist-like water droplets to adsorb dust in the air and cause it to settle, which can effectively reduce the dust generated during belt transportation. However, currently, coal mine conveyors with dust suppression functions often do not have spray head angle adjustment function, which can easily cause uneven spraying of coal, resulting in poor dust suppression effect on some coal.

[0004] In view of this, we propose a coal mine conveyor with dust reduction function. Utility Model Content

[0005] The purpose of this invention is to provide a coal mine conveyor with dust reduction function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A coal mine conveyor with dust suppression function includes a base, a conveyor belt mounted on the base, a conveyor frame fixedly mounted on the top surface of the base, a water pump mounted on the side wall of the conveyor frame, a water storage device fixedly connected to the water inlet of the water pump, a collection box snapped onto the side wall of the base, and a dust suppression component mounted on the base. The dust suppression component includes:

[0008] A dual-axis motor is fixedly installed inside the conveyor frame. One end of the output shaft of the dual-axis motor is fixedly installed, and a first bevel gear is fixedly installed at the other end of the shaft. A fixed frame is fixedly installed inside the conveyor frame.

An atomizing nozzle is provided on the bottom of the connecting plate. The connecting plate is hinged to the bottom of the bracket via a connecting rod. The bracket is fixedly mounted on the bottom of the conveyor frame. One end of a water supply pipe is fixedly mounted on the top of the connecting plate. The other end of the water supply pipe is fixedly connected to the inside of the conveyor frame.

[0011] In a further embodiment, the atomizing nozzles are provided in multiple sets to better spray water mist.

[0012] In a further embodiment, multiple sets of the atomizing nozzles are arranged in a linear array with equal spacing.

[0013] In a further embodiment, the atomizing nozzle is positioned directly above the conveyor belt, thereby ensuring more even spraying.

[0014] In a further embodiment, the water supply pipe is a flexible hose, and the water supply pipe, atomizing nozzle, connecting plate, conveying frame, and internal space of the water pump are interconnected.

[0015] In a further embodiment, a dust collection assembly is provided on the conveyor belt.

[0016] In a further embodiment, the dust collection box is connected to the internal space of the vacuum cleaner.

[0017] Compared with the prior art, this utility model provides a coal mine conveyor with dust reduction function, which has the following beneficial effects:

[0018] 1. This coal mine conveyor with dust suppression function can swing at multiple angles to make the dust suppression nozzles spray more evenly on the coal.

It is primarily used to better describe this application and its embodiments, and is not intended to limit the indicated device, element, or component to having a specific orientation, or to construct and operate in a specific orientation. Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0031] Please see Figures 1-5 This utility model provides a technical solution:

[0032] A coal mine conveyor with dust suppression function includes a base 1, a conveyor belt 2 on the base 1, a conveyor frame 3 fixedly installed on the top surface of the base 1, a water pump 31 on the side wall of the conveyor frame 3, a water storage device fixedly connected to the water inlet end of the water pump 31, and a collection box 4 snapped onto the side wall of the base 1.

[0033] In one embodiment of this utility model, a dust-suppressing component 5 is provided on the base 1. The dust-suppressing component 5 includes a dual-axis motor 51. The dual-axis motor 51 is fixedly installed inside the conveyor frame 3. One end of the rotating shaft 52 is fixedly installed at the output end of the dual-axis motor 51. A first bevel gear 53 is fixedly installed at the other end of the rotating shaft 52. A fixed frame 54 is fixedly installed inside the conveyor frame 3. One end of a driven rod 55 is rotatably installed inside the fixed frame 54 through bearing components. A second bevel gear 56 is fixedly installed in the middle of the driven rod 55. The first bevel gear 53 meshes with the second bevel gear 56. A gear disk 57 is fixedly installed at the other end of the driven rod 55. A sector gear 58 is rotatably installed on the side wall of the conveyor frame 3 through bearing components. The gear disk 57 meshes with the sector gear 58. A rectangular block 59 is fixedly installed on the bottom of the gear 58. A connecting plate 510 is fixedly installed on the bottom of the rectangular block 59. An atomizing nozzle 511 is provided on the bottom of the connecting plate 510. The connecting plate 510 is hinged to the bottom of the bracket 513 via a connecting rod 512. The bracket 513 is fixedly installed on the bottom of the conveyor frame 3. One end of a water supply pipe 514 is fixedly installed on the top of the connecting plate 510. The other end of the water supply pipe 514 is fixedly connected to the inside of the conveyor frame 3. Multiple sets of atomizing nozzles 511 are provided. The multiple sets of atomizing nozzles 511 are arranged in a linear array with equal spacing. The atomizing nozzles 511 are located directly above the conveyor belt 2. The water supply pipe 514 is a flexible hose. The water supply pipe 514, the atomizing nozzles 511, the connecting plate 510, the conveyor frame 3, and the internal space of the water pump 31 are connected.

[0034] In this embodiment, when dust suppression is required for the coal continuously conveyed on the conveyor belt 2, the dual-shaft motor 51 is started. The dual-shaft motor 51 is an asynchronous motor, which drives the rotating shaft 52 to reciprocate continuously in the forward and reverse directions. The first bevel gear 53 starts to rotate with the rotating shaft 52. The continuous rotation of the first bevel gear 53 transmits the rotational power to the second bevel gear 56. The second bevel gear 56 rotates synchronously, causing the driven rod 55 to rotate. When the gear disk 57 rotates, it drives the sector gear 58 to oscillate back and forth. The rectangular block 59 will make arc-shaped movements with the oscillation of the sector gear 58 and transmit the motion to the connecting plate 510. The connecting plate 510 is connected to the support 5 by the connecting rod 512. The hinge point of 13 is the axis, which swings within a certain angle range. At the same time, the water pump 31 uses the suction force generated by the rotation of its impeller to draw water out of the water storage device. The water flows into the internal space of the conveyor frame 3 and is then transported to the atomizing nozzle 511 through the water pipe 514. The atomizing nozzle 511 disperses the water flow into fine water mist particles. During the process of the connecting plate 510 driving the atomizing nozzle 511 to swing at multiple angles, these atomizing nozzles 511 will continuously spray water mist onto the surface of the coal on the conveyor belt 2. The water mist can evenly cover all parts of the coal, making the spraying of water mist on the coal more uniform, thereby achieving a better coal dust reduction effect.

[0035] In one embodiment of this utility model, a dust collection component 6 is provided on the conveyor belt 2. The dust collection component 6 includes a fixed platform 61. The fixed platform 61 is fixedly installed on the side wall of the conveyor belt 2. A dust collection box 62 is fixedly installed on the top surface of the fixed platform 61. A vacuum cleaner 63 is provided at one end of the dust collection box 62 near the conveyor belt 2. An exhaust pipe 64 is fixedly installed on the top of the dust collection box 62. The dust collection box 62 is connected to the internal space of the vacuum cleaner 63.

[0036] In this embodiment, during dust suppression, the vacuum cleaner 63 is turned on simultaneously. Under the negative pressure of the vacuum cleaner 63, air begins to flow and generate suction. Dust on the coal surface of the conveyor belt 2 caused by vibration and the conveying process, as well as fine dust that was not completely adsorbed after the water mist sprayed by the dust suppression component 5 and is suspended in the gap area, are sucked into the vacuum cleaner 63 under the action of suction. The dust-laden air is drawn into the dust collection box 62 through the pipe. The dust collection box 62 is usually equipped with a filter screen or other filtration device. These filtration structures can effectively intercept dust particles in the air. After the dust is blocked by the filter screen, it will gradually settle in the dust collection box 62. The relatively clean air after filtration is discharged through the exhaust pipe 64, which makes up for the shortcomings of simple water mist dust suppression in dealing with fine suspended dust, thereby achieving more comprehensive cleaning of dust on the coal surface and surrounding gap area of ​​the conveyor belt 2.

[0037] All electrical components mentioned in this application are electrically connected to the controller and 220V AC mains power. The controller is a conventional and known device that can control the conveyor belt 2, water pump 31, dual-axis motor 51, and vacuum cleaner 63. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. The machinery, parts, and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
