Description

Technical Field

[0001] The utility model relates to the technical field of coal mine dust reduction, in particular to a dust reduction device used in coal mines. Background Art

[0002] During coal mining, operations such as blasting, excavation, and transportation generate a large amount of coal dust, including the coal itself and the use of various mechanical equipment during the operation. This coal dust not only affects the working environment, but also poses a serious threat to the health of miners, equipment safety, and the environment.

[0003] Existing underground coal mines usually use wet dust suppression, that is, water spray devices are installed in places where dust is more concentrated to settle the coal dust. However, these water spray devices are generally fixed and difficult to move, and the spraying range is relatively fixed, so they can only suppress dust in a small area, which affects the dust suppression effect. At the same time, spraying too much water will cause the ground to be too wet, thereby affecting the normal walking of workers and the movement of equipment. Therefore, we designed a dust suppression device for underground coal mines. Utility Model Content

[0004] The utility model aims to provide a dust suppression device for use in coal mines, which can change the angle and range of the spray, thereby achieving mobile and comprehensive dust suppression, ensuring the dust suppression effect, and collecting the coal dust after dust suppression to prevent secondary impacts, thereby solving the problems raised in the background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a dust suppression device for use in coal mines includes a supporting base, a side surface of the supporting base is movably connected to a moving wheel, an outer side of the moving wheel is transmission-connected to a crawler, an upper surface of the supporting base is movably connected to a movable disk, a driving motor is fixedly installed on the bottom of the supporting base, and an output end of the driving motor passes through the supporting base and is fixedly connected to the movable disk, an upper surface of the movable disk is fixedly connected to a water tank, a water pump is fixedly installed on the top of the water tank, a water outlet end of the water pump is fixedly connected to a water inlet end of a connecting pipe, a water outlet end of the connecting pipe is fixedly connected to a water inlet end of a water outlet pipe, and a water outlet end of the water outlet pipe is fixedly connected to a spray head;

A through-hole is provided in the horizontal plate, and the water outlet pipe is located in the through-hole. The outer side of the water outlet pipe is fixedly connected to a fixing ring, and the outer side of the fixing ring is fixedly connected to a rotating rod, and the end of the rotating rod away from the fixing ring is movably connected to the vertical plate. A servo motor is fixedly installed on the side of the vertical plate, and the output end of the servo motor passes through the vertical plate and is fixedly connected to the corresponding rotating rod. A collection component is also provided on the water tank.

[0007] Through the above technical solution, the present application starts the water pump to spray the water in the water tank through the connecting pipe and the water outlet pipe and through the spray head to reduce dust, starts the servo motor to drive the fixed ring and the water outlet pipe to rotate, thereby adjusting the bending angle of the water outlet pipe, and then changing the spraying angle of the spray head. Starting the drive motor can drive the movable disk, water tank and spray head to rotate, so that the spray head can adjust the spray range while rotating, thereby achieving comprehensive dust reduction. At the same time, it can also carry out targeted dust reduction at a location with more coal dust, which is more practical. Finally, the water mist that absorbs the coal dust falls into the collection component by gravity for collection. At the same time, the design of the moving wheels and tracks is more in line with the underground working environment of coal mines, and the movement is more stable.

[0008] Preferably, the connecting pipe is a soft water pipe, the water outlet pipe is a hard water pipe, and the diameter of the perforation is larger than the diameter of the water outlet pipe.

[0009] Through the above technical solution, the present application is easier to rotate when the fixed ring drives the water outlet pipe to rotate, and the connecting pipe will follow the deformation without affecting the normal water supply.

[0010] Preferably, the collecting assembly includes a plywood, a stretching rod and a tarpaulin, the upper surface of the water tank is fixedly connected to the plywood, a stretching rod is arranged between the plywood, and the bottom end of the stretching rod is movably connected to the plywood through a rotating shaft, the number of the stretching rods is several and distributed in a ring shape with the axis of the water tank as the center, and the tarpaulin is fixedly connected between the stretching rods.

[0011] Through the above technical solution, the present application rotates the stretching rod to tilt the stretching rod and stretch the tarpaulin, so that the area formed by the tarpaulin becomes larger, and the water mist that absorbs the coal dust can fall onto the tarpaulin for unified collection.

[0012] Preferably, the stretching rod is located outside the vertical plate, and the total length of the connecting pipe and the water outlet pipe is greater than the length of the stretching rod.

[0014] Preferably, an electric telescopic rod is fixedly installed on the top of the water tank, and the output end of the electric telescopic rod is fixedly connected to a limit block, and the limit block is in contact with the stretching rod.

[0015] Through the above technical solution, the height of the limit block can be adjusted in the present application to change the inclination angle of the stretch rod, thereby adapting to different usage locations and changing the stretching area of ​​the tarpaulin.

[0016] Preferably, a collection frame is fixedly connected to the outer side of the water tank, and a drainage hole is provided on the collection frame.

[0017] Through the above technical solution, the water mist collected on the tarpaulin of the present application will slide into the collection frame, or be cleaned by spraying water, and finally discharged through the drainage hole.

[0018] By adopting the above technical solution, the beneficial effects of the utility model are:

[0019] 1.
