Technical Field

[0001] The utility model relates to the field of coal mine dust reduction equipment, and particularly relates to a crushing dust reducer for coal mines. Background Art

[0002] Whether it is an underground coal mine or an open-pit coal mine, the mined coal needs to be crushed and then transported. The dust generated during the crushing process is particularly large. If not properly handled, there is a risk of combustion and explosion, which also affects the health of personnel in the environment and does not meet environmental protection regulations.

[0003] The main dust reduction method in the coal mine crushing process is spray dust reduction. To prevent dust from spreading, generally, the boundary is demarcated for enclosure, and then spray dust reduction is carried out. This method requires the prior installation of enclosure equipment. Once an expansion is needed, major demolition and reconstruction are required, which is very troublesome. Therefore, a crushing dust reducer for coal mines is proposed. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following describes the preferred embodiments of the present utility model with reference to the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0021] Among them, the same reference numerals in the drawings all refer to the same components.

[0022] Embodiment 1

[0023] As shown Figures 1-3 in the figure, the utility model provides a crushing and dust reducing device for coal mines, which includes a telescopic rod 1 and a hose 3 fixed on the telescopic rod 1. The telescopic rod 1 includes an outer tube 11 and an extension rod 12. The extension rod 12 is inserted into the outer tube 11 from the top of the outer tube 11. Positioning sleeves 2 are bonded to the back of the outer tube 11 and the back of the extension rod 12 respectively. Two hoses 3 are respectively sleeved in the positioning sleeves 2 on the outer tube 11 and the extension rod 12. The number of telescopic rods 1 is multiple, and the number of hoses 3 is two. The bottom of the hose 3 is communicated with an atomizing nozzle 4. One end of the hose 3 is communicated with a water pumping assembly. The water pumping assembly includes a horizontal tube 5, a water pump 6, a water delivery pipe 7 and a water suction pipe 8. The water outlet and the water suction port of the water pump 6 are respectively communicated with the water delivery pipe 7 and the water suction pipe 8. One end of the horizontal tube 5 is communicated with the hose 3, and the other end of the horizontal tube 5 is communicated with the water delivery pipe 7.

[0024] In addition, a positioning plate 61 is fixedly arranged at the bottom of the water pump 6, and the positioning plate 61 can be fixed by screws. The water delivery pipe 7 is a telescopic hose (such as a corrugated pipe), and the length of the water delivery pipe 7 can be adjusted according to actual needs. Multiple water delivery pipes 7 can be spliced together using connectors, or the water delivery pipe 7 can be cut short.

[0025] Furthermore, a bottom plate 9 is fixedly arranged at the bottom of the outer tube 11. Positioning screws 91 penetrating through to the lower side of the bottom plate 9 are threadedly connected to the left and right sides of the top of the bottom plate 9. After placing the bottom plate 9 at a suitable position on the ground, rotate the positioning screws 91 to move downward and pierce into the ground. If the selected telescopic rod 1 is relatively high or the water flow in the hose 3 is relatively large, heavy objects can be pressed on the bottom plate 9 to maintain stability.

[0026] Specifically, a threaded sleeve 13 is fixedly arranged on the outer tube 11. An adjusting screw rod 14 penetrating through to the inside of the outer tube 11 is threadedly connected to one side of the threaded sleeve 13. A pressing head 15 is fixedly arranged at one end of the adjusting screw rod 14 located inside the outer tube 11. The pressing head 15 is used to press tightly against the side of the extension rod 12 for positioning it.

[0027] In summary, by setting the telescopic rod 1 and the hose 3, the range enclosed by the hose 3 can be adjusted by adjusting the position of the telescopic rod 1, and a dust enclosure can be easily arranged. The water mist sprayed by the atomizing nozzle 4 settles the dust. When adjusting the enclosure range, only the position of the telescopic rod 1 needs to be adjusted. Compared with setting a baffle-type enclosure, using the combination of the telescopic rod 1 and the hose 3 is more convenient for disassembly and assembly and has a lower cost.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
