Description

TECHNICAL FIELD

[0001] The utility model belongs to the underground transportation equipment technical field, concretely relates to a kind of transportation equipment for underground mining. BACKGROUND

[0002] Coal mine is the core place of coal resources exploitation, and is divided into underground coal mine and open pit coal mine according to the different depth of coal seam. Among them, underground coal mine needs to carry out coal mining through underground roadway, and its operation environment has the characteristics of narrow space, insufficient light, high dust concentration. In the coal transportation link, the traditional transportation equipment (such as conveyor belt) needs to transfer coal from underground to ground through segmented transportation, and the process of coal accumulation, collision and vibration is easy to cause a large amount of coal dust to escape. These dust not only pollutes the underground air, affects the respiratory health of workers, and long-term exposure may cause pneumoconiosis and other occupational diseases; in addition, high concentration of coal dust has the risk of explosion, which seriously threatens the safety of underground operation.

[0003] In view of the above problems, the prior art puts forward an improved scheme. For example, Chinese patent "coal mine transportation equipment for underground mining of coal mine" (authorized publication number: CN22092573U) discloses a design integrating conveying mechanism and dust falling mechanism. The device includes a bottom plate, a connecting plate, a conveying mechanism and a dust falling mechanism, and its core principle is to transport coal by conveyor belt at the same time, and to spray water mist or dust suppressant by dust falling mechanism to suppress dust diffusion. Specifically, the dust falling mechanism is usually composed of a water tank, a pump body and a spray head, and the spray head is arranged along the two sides or above the conveyor belt, and the surface of coal pile is treated by wetting during transportation. However, this design has significant defects in practical application, such as:

[0004] 1. The surface dust falling effect is limited, because the coal blocks are in the state of accumulation during transportation, the water sprayed by the spray head can only cover the surface layer of the coal pile, and cannot penetrate into the gap between the internal coal blocks, so that the internal coal dust is still in dry state.

[0005] 2. Dynamic dust raising is difficult to suppress, in the subsequent transportation process, the vibration of conveyor belt, friction and bumping between coal blocks will cause internal coal dust to fly again, and the residual dust will be released after the surface wet coal block dries.

[0006] 3. Resource waste and low efficiency, in order to achieve a certain dust falling effect, a large amount of water needs to be sprayed, which not only increases the consumption of water resources, but also may cause coal clumping due to excessive wetting, affecting the subsequent processing and combustion efficiency.

[0007] Based on this, the utility model provides a kind of transportation equipment for underground mining, to solve the problems existing in the prior art. UTILITY MODEL CONTENT

[0043] As shown in the accompanying drawings for the description Figures 1-6 The utility model provides a technical scheme:

[0044] A kind of transport equipment for underground mining, including conveyer body 1, dust fall mechanism 2 and dispersion mechanism 3 being arranged on conveyer body 1;Wherein:

[0045] The dust fall mechanism 2 is arranged on the upside of conveyer body 1, for spraying water on the surface of coal material in the transportation process of conveyer body 1, to achieve the effect of preliminary dust prevention;

[0046] The dispersion mechanism 3 is arranged in conveyer body 1 and is fixedly connected with the side wall of conveyer body 1, for preventing the phenomenon of coal block falling in the side transportation process of conveyer body 1.

[0047] In a preferred embodiment, as shown in Figure 1 And Figure 2 The dust fall mechanism 2 includes water tank 4 arranged on one side of conveyer body 1, the water tank 4 is communicated with water pipe 21 installed on the upside of conveyer body 1 by water pipe 24, water tank 4 injects water into water pipe 21 by water pipe 24 in use, and a plurality of spray openings for spraying water are formed on the downside of water pipe 21 towards one side of conveyer body 1, for spraying water to the surface of coal block pile through spray opening, to realize the effect of dust fall on coal block pile.

[0048] Specifically, as shown in Figure 1 And Figure 2 Water pump 23 is further arranged on water pipe 24, for pressurizing water by water pump 23, so that it can be sprayed on the surface of coal block pile.

[0049] Specifically, as shown in Figure 1 AndFigure 2 As shown in the drawings, the water spraying pipe 21 is installed on the upper side of the conveyor body 1 through the electric telescopic rod 22, and the electric telescopic rod 22 can be powered according to the needs in use, and the length of the electric telescopic rod 22 is adjusted so that the installation height of the water spraying pipe 21 can meet the spraying needs.

[0050] In a preferred embodiment, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the dispersion mechanism 3 includes guide plates 32 symmetrically installed on the side wall 11 of the conveyor body 1, and a dispersion block 31 is arranged between the opposite sides of the two guide plates 32, and the dispersion block 31 is of an arc-shaped structure; the dispersion mechanism 3 further includes an air pump 37 fixed to one side of the conveyor body 1, and the air outlet end of the air pump 37 is communicated with the internal cavity of the dispersion block 31 through an air pipe 38; and a plurality of air outlet holes 35 are further arranged on the upper side surface of the dispersion block 31 and communicated with the internal cavity of the dispersion block 31, and the air outlet holes 35 are arranged in three rows.

[0051] In the above description, when the coal block pile contacts the dispersion block 31, the coal block will be displaced upward along the dispersion part because the dispersion block 31 is designed in a conical shape, at this time the air pump 37 is opened, the air pump 37 will inject air into the cavity of the dispersion block 31, at this time the gas in the internal cavity of the dispersion block 31 will be blown out from the air outlet holes 35 on the surface of the dispersion block 31, which can blow away the dust in the coal block pile, and the dust on the surface of the coal block can be removed as much as possible, and the continuously conveyed coal block pile will be dispersed to both sides by the dispersion block 31, and the coal block below the coal block pile will be turned out when the coal block pile is dispersed, because the dust removal mechanism 2 is continuously sprayed with water, the dust in the coal block pile will also be adhered by the water, which can prevent the dust in the coal block pile from being hidden and causing dust raising phenomenon in the subsequent transportation process.

[0052] It should be noted that the dispersion block 31 is located between the two guide plates 32, and the guide plates 32 are fixed to the inner side of the side wall 11 of the conveyor body 1, so that the lower side of the dispersion block 31 does not contact the conveyor body 1, and the problem of blocking the operation of the conveyor belt in the conveyor body 1 does not occur;

[0053] Specifically, as shown in Figure 5 and Figure 6 , an included angle part 36 is arranged between the guide plate 32 and the dispersion block 31, and the angle of the included angle part 36 is upward and relatively inward;

[0054] The converging plate 33 is fixedly connected between the two guide plates 32 and is arc-shaped.

[0055] In the above description, after the coal blocks are dispersed by the dispersion blocks 31, the coal blocks will fall into the converging plate 33 along the inclined part 34, and since the converging plate 33 is arc-shaped, the arc-shaped part of the converging plate 33 can converge the two coal block piles to each other, which can effectively prevent the coal blocks from falling off during the transportation of the side of the conveyor body 1.

[0056] When the coal blocks are transported to the lower side of the dust-settling mechanism 2, the dust-settling mechanism 2 will first spray water on the surface of the coal blocks, so that the water can adhere to the dust on the surface of the coal blocks, and the effect of preliminary dust prevention can be achieved.

[0057] It should be noted that in the above description, the conveyor body 1, the water pump 23, the air pump 37 and the water tank 4 are all relatively mature devices in the prior art, and the specific model can be selected according to actual needs, and the specific power supply mode can be selected to use mains power or a mobile power supply, which will not be described here.

[0058] The above is only a preferred embodiment of the present application, and is not intended to limit the scope of protection of the present application.
