Description

[0002] In the coal mining process, coal unloading is an essential and important link. Traditional unloading equipment often has problems such as incomplete unloading and serious coal dust flying. Compared with traditional unloading methods, the plow type unloader generates less noise and dust during the unloading process, and has less impact on the environment.

[0003] With reference to the Chinese patent, the application number is "201711115440.1" for "a vertically liftable plow type discharger", which solves the problem that in the field of bulk material transportation, in specific environments such as fixed-point unloading, the installation space is limited and the unloading effect must be achieved; the currently commonly used discharger uses the plow head to tilt up to achieve the flattening and grooving of the movable roller group; under the condition of limited installation space, the currently commonly used discharger cannot meet the on-site use conditions and there is a possibility that the tape will collide with the plow head structure and scratch the tape. However, when the existing plow type discharger is used in the coal mine production process, although the noise and dust generated are less, when the coal falls into the coal box, coal dust is still inevitably raised, causing pollution.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention provides three technical solutions, including the following embodiments:

[0028] Example 1

[0029] See also Figure 1-Figure 3 A plough type discharger with dust removal function for coal mining includes a bracket 1. The stable bracket 1 serves as the basis of the entire device. A discharger body 2 is arranged on the top of the bracket 1. The discharger body 2 is a plough type discharger. The plough type discharger is a prior art. The plough type discharger is mainly composed of a plow blade, a discharge chute and a discharge slide. Its working principle is to use the plow blade to scrape the moving conveyor belt, guide the material to the discharge chute, and deliver it to the designated position through the slide. This discharge method has a simple structure. , flexible operation, high unloading efficiency, a conveyor belt 3 is installed on the bracket 1, coal is transported on the conveyor belt 3, the conveyor belt 3 is controlled by an external switch and electrically connected to an external power supply, a coal collecting box 4 is fixed on one side of the bracket 1, the coal collecting box 4 is used to collect the unloaded coal, and a mobile dust removal mechanism 5 for spraying water to reduce dust during unloading is provided on the coal collecting box 4. The mobile dust removal mechanism 5 can spray water mist evenly in the unloading area, effectively suppress the flying of coal dust, and protect the working environment and the health of workers;

[0030] The mobile dust removal mechanism 5 includes two vertical plates 51 fixed on one side of the coal collecting box 4, a screw rod 52 is rotatably connected between the opposite sides of the two vertical plates 51, a moving seat 53 is slidably connected to one side of the coal collecting box 4, one end of the screw rod 52 passes through the moving seat 53 and extends to the outside of the moving seat 53, the outer surface of the screw rod 52 is threadedly connected to the inner surface of the moving seat 53, and a motor 1 54 is fixed on one side of one of the vertical plates 51. The motor 1 54 is a three-phase asynchronous motor that can rotate forward and reverse, is controlled by the touch switch 1 6 and the touch switch 2 7, and is electrically connected to the external power supply. The motor 1 54 drives the screw rod 52 to rotate, and the moving seat 53 is moved. A water tank 55 is fixed to one side of the moving seat 53. The water tank 55 contains water and a water pump is installed inside. The water pump is electrically connected to an external power supply and is controlled by an external switch. A water inlet pipe 56 is connected to one side of the water tank 55. Water enters the water tank 55 through the water inlet pipe 56 and is stored. Three vertical pipes 57 are connected to the top of the water tank 55. The liquid outlet of the water pump is connected to the three vertical pipes 57, so that the water in the water tank 55 can be pumped out. The tops of the three vertical pipes 57 are all connected to horizontal pipes 58. One ends of the three horizontal pipes 58 are all connected to nozzles 59. The nozzles 59 can spray water in the form of water mist, and the sprayed water mist can suppress the raised coal dust.

[0033] Example 2

[0034] Based on Example 1, see Figure 2 and Figure 4As shown, the mobile dust removal mechanism 5 is provided with a mobile grader assembly 8 for evenly spreading the coal inside the coal box 4. The setting of the mobile grader assembly 8 enables the coal to fill the coal box 4 faster and more evenly, reducing the problem of prolonged unloading time caused by accumulation. At the same time, the uniform distribution of coal improves the space utilization rate of the coal box 4, providing convenience for subsequent processing. The mobile grader assembly 8 includes a mobile box 81 slidably connected to the bottom wall of the coal box 4, a hook rod 82 is fixed to one side of the top of the mobile box 81, one end of the hook rod 82 is fixed to the top of the mobile seat 53, and a plurality of grader pipes 83 are fixed to the top of the mobile box 81. The setting of the grader pipes 83 can evenly rake the accumulated coal material during the horizontal reciprocating movement, so that the coal material is evenly spread in the coal box 4.

[0035] By setting up the mobile material leveling component 8, during the process of the mobile dust removal mechanism 5 performing mobile dust reduction, the material leveling pipe 83 can be synchronously driven to perform horizontal reciprocating movement, so as to rake the coal accumulated in the coal box 4 and spread the coal evenly in the coal box 4, thereby avoiding the phenomenon of unloading accumulation and improving the unloading efficiency.

[0036] Example 3

[0037] Based on Example 2, see Figure 4-Figure 6 As shown, the mobile dust removal mechanism 5 is provided with a loosening unit 9 for loosening the accumulated coal material. The loosening unit 9 effectively prevents the problem of coal material sticking together after water spraying to reduce dust, ensures the loose state of the coal material, and facilitates subsequent processing and transportation. The loosening unit 9 includes a rotating rod 91 rotatably connected to the inside of the hook rod 82, and a motor 2 92 is fixed to the top of the hook rod 82. The motor 2 92 is a three-phase asynchronous motor that can be reversed. The motor 2 92 is controlled by an external switch and is electrically connected to an external power supply. The motor 2 92 drives the rotating rod 91 to rotate, and the bottom end of the rotating rod 91 extends to the inside of the mobile box 81.

[0038] A bevel gear 1 93 is fixed to the bottom end of the rotating rod 91 , a threaded rod 94 is rotatably connected between the inner walls of the moving box 81 , a bevel gear 2 95 is fixed to the outer surface of the threaded rod 94 , the bevel gear 1 93 is meshed with the bevel gear 2 95 , and a slide seat 96 is slidably connected between the inner walls of the moving box 81 .

[0039] One end of the threaded rod 94 passes through the slide 96 and extends to the outside of the slide 96. The outer surface of the threaded rod 94 is threadedly connected to the inner surface of the slide 96. A fan-shaped protrusion 97 is fixed to the top of the slide 96. The interiors of the multiple material mixing tubes 83 are all slidably connected with loosening rods 98.

[0040] Top ends of the plurality of loosening rods 98 penetrate the material mixing tube 83 and extend to the top of the material mixing tube 83 . A limiting plate 99 is fixed to the outer surface of the loosening rod 98 , and the bottom of the limiting plate 99 contacts the top of the material mixing tube 83 .

[0041] The bottom end of the loosening rod 98 passes through the material mixing pipe 83 and extends to the interior of the moving box 81. The bottom end of the loosening rod 98 is set as a spherical protrusion 910. The outer surface of the fan-shaped protrusion 97 is in contact and extrusion with the outer surface of the spherical protrusion 910. When the fan-shaped protrusion 97 is in contact and extrusion with the spherical protrusion 910, the loosening rod 98 can be driven to push upward, and then the loosening rod 98 can loosen the coal material and make it loose.

[0042] By setting the loosening unit 9, in the process of horizontal reciprocating raking of the mobile material leveling assembly 8, the coal is loosened by lifting up the loosening rods 98 in sequence, thereby avoiding the problem of coal sticking together after being wetted by water spraying and dust reduction, which makes it difficult to discharge the coal. After loosening, the coal can be made loose, making it convenient to discharge the coal.

[0043] Through the close collaboration of the three major functions of dust removal, material leveling and material loosening, the entire process of coal mine unloading, collection and processing has been optimized, significantly improving operational efficiency and environmental protection effects.

[0044] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0045] During operation, the coal is placed on the conveyor belt 3 for transmission, the unloader body 2 is started, and the coal is unloaded into the coal collecting box 4 using the plow cutter on the unloader body 2, and the motor 54 is started, so that the motor 54 drives the screw rod 52 to rotate, and the screw rod 52 drives the moving seat 53 and the water tank 55 to move to the right. When the water tank 55 moves to the far right, the touch switch 16 on the water tank 55 contacts the touch switch 27 on the right side, so that the motor 154 is reversed, and then the water tank 55 is driven to move to the left. When the touch switch 16 contacts the touch switch 27 on the left side, the motor 154 is reversed again, so that the water tank 55 moves to the right, realizing left and right reciprocating movement, and the water pump in the water tank 55 is started. , water is sprayed out through the nozzle 59, and water is sprayed to reduce dust while moving back and forth left and right. On the other hand, the moving seat 53 drives the moving box 81 and the material-scraping pipe 83 to move back and forth left and right in the coal collecting box 4. During the movement of the material-scraping pipe 83 left and right, the accumulated coal is raked and the coal is evenly spread in the coal collecting box 4. The motor 2 92 is further started to drive the threaded rod 94 to rotate, thereby driving the slide 96 to move back and forth, thereby driving the fan-shaped protrusion 97 to regularly drive the loosening rod 98 to lift up in sequence, and the loosening rod 98 is used to loosen the accumulated coal moistened by the water spray. After loosening, the coal becomes loose, which is convenient for discharging.

[0046] The above embodiments of the invention are described in detail, but the contents are only preferred embodiments of the invention and cannot be considered to limit the scope of the invention. All equivalent changes and improvements made within the scope of the invention should still fall within the scope of the invention.
