Description

Technical Field

[0001] This utility model relates to the field of dust suppression technology in coal mines, and in particular to a dust suppression device for open-pit coal mines. Background Technology

[0002] Coal mines are areas where humans extract coal resources in coal-rich mining areas. When the coal seam is very close to the surface, the coal is usually mined by directly stripping the surface soil layer. This is called an open-pit coal mine. Dust control measures in open-pit coal mines are very important, mainly to reduce the harm of coal dust to the environment and human health.

[0003] A dust suppression device for coal mines (authorization announcement number: CN209457969U) allows for adjustment and fixation of the nozzle height and deflection angle by manually adjusting a fixing pin and a rotating pin. While this provides the dust suppression device with adjustable spray height and deflection angle, it is inconvenient to simultaneously adjust the nozzle's reciprocating lifting and deflection during actual water spraying dust suppression in coal mines. This limits the coverage area of ​​the water spraying dust suppression and reduces the working efficiency of the dust suppression device. Therefore, this utility model is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dust suppression device for open-pit coal mines, which solves the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dust suppression device for open-pit coal mines includes a base, an mounting frame fixedly installed on the top side of the base, a lifting slot provided in the mounting frame, a lifting plate movably installed in the lifting slot, a lifting adjustment drive mechanism for the lifting plate provided on the top side of the mounting frame, two rotating slots provided in the lifting plate, spray cylinders rotatably installed in each of the two rotating slots, multiple water spray heads provided on each of the two spray cylinders, a rolling mechanism for the rotating slots provided on the spray cylinders, a first chamber and a second chamber provided in the mounting frame, a transmission mechanism provided on the bottom side of each of the two spray cylinders, and a deflection adjustment drive mechanism for the transmission mechanism provided in the second chamber of the mounting frame.

[0007] Preferably, the lifting adjustment drive mechanism includes a first motor and a threaded rod. The first motor is fixedly installed on the top side of the mounting bracket, and one end of the threaded rod is fixedly installed on the output shaft of the first motor. The other end of the threaded rod is threaded through the outside of the lifting plate and rotatably installed on the bottom inner wall of the lifting slot. By starting the first motor, the threaded rod can be reciprocated to achieve height adjustment of the two spray cylinders on the lifting plate.

[0008] Preferably, the rolling mechanism includes wheel grooves and rollers. Multiple wheel grooves are respectively opened on the outer surface of the spraying cylinder. Rollers are rotatably installed in each of the multiple wheel grooves through a rotating shaft. The contact surfaces of the multiple rollers roll against the inner wall of the wheel groove. When the spraying cylinder rotates, the multiple rollers on the spraying cylinder roll on the inner wall of the corresponding rotating groove in the lifting plate, which facilitates the reciprocating rotation of the two spraying cylinders in the lifting plate.

[0009] Preferably, the transmission mechanism includes a transmission rod and a transmission gear. One end of the transmission rod is fixedly installed on the bottom side of the spray cylinder, and the other end of the transmission rod extends movably into the first chamber and is fixedly installed with the transmission gear. When the transmission gear on the transmission rod rotates, it can drive the spray cylinder to rotate.

[0010] Preferably, the deflection adjustment drive mechanism includes a second motor and a gear column. The second motor is fixedly installed in the second chamber of the mounting bracket. The output shaft of the second motor extends rotatably into the first chamber and is fixedly installed with a gear column. The gear column meshes with two transmission gears. By starting the second motor, the gear column is made to reciprocate at a certain angle. Since the gear column meshes with the two transmission gears, it synchronously drives the two sets of transmission rods and the spray cylinder to reciprocate at an angle.

[0011] Preferably, each of the two spray cylinders is connected to one end of a water supply hose, and the two water supply hoses on the two spray cylinders are connected together. The mounting bracket has two side openings respectively. Water is delivered to the two spray cylinders through the water supply hoses via an external water supply device.

[0012] The beneficial effects of this utility model are as follows: This open-pit coal mine dust suppression device, by starting the second motor, causes the gear column to reciprocate at a certain angle, synchronously driving the two sets of transmission rods and spray cylinders to reciprocate at a 120-degree angle, thereby increasing the coverage of the dust suppression spray from multiple spray heads on the two spray cylinders. At the same time, in conjunction with the drive first motor, it can drive the threaded rod to reciprocate, causing the lifting plate to reciprocate and adjust its height within the lifting slot of the mounting frame. This allows for simultaneous reciprocating height adjustment of the two spray cylinders on the lifting plate, thus improving the working efficiency of the open-pit coal mine dust suppression device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1-5 A dust suppression device for open-pit coal mines includes a base 1, an mounting frame 2 fixedly installed on the top side of the base 1, a lifting slot 3 opened in the mounting frame 2, a lifting plate 4 movably installed in the lifting slot 3, a lifting adjustment drive mechanism for the lifting plate 4 provided on the top side of the mounting frame 2, two rotating slots 7 respectively opened in the lifting plate 4, spray cylinders 8 rotatably installed in both rotating slots 7, multiple water spray heads 9 provided on both spray cylinders 8, a rolling mechanism for the rotating slots 7 provided on the spray cylinders 8, a first chamber 12 and a second chamber 13 respectively opened in the mounting frame 2, a transmission mechanism provided on the bottom side of both spray cylinders 8, and a deflection adjustment drive mechanism for the transmission mechanism provided in the second chamber 13 of the mounting frame 2.

[0021] Furthermore, the lifting and adjusting drive mechanism includes a first motor 5 and a threaded rod 6. The first motor 5 is fixedly installed on the top side of the mounting bracket 2. One end of the threaded rod 6 is fixedly installed on the output shaft of the first motor 5. The other end of the threaded rod 6 is threaded through the outside of the lifting plate 4 and rotatably installed on the bottom inner wall of the lifting slot 3. By starting the first motor 5, the threaded rod 6 can be reciprocated to achieve the lifting and adjusting of the height of the two spray cylinders 8 on the lifting plate 4.

[0022] Furthermore, the rolling mechanism includes wheel grooves 10 and rollers 11. Multiple wheel grooves 10 are respectively opened on the outer surface of the spray cylinder 8. Rollers 11 are rotatably installed in the multiple wheel grooves 10 through rotating shafts. The wheel contact surfaces of the multiple rollers 11 roll and adhere to the inner wall of the wheel groove 10. When the spray cylinder 8 rotates, the multiple rollers 11 on the spray cylinder 8 roll on the inner wall of the corresponding rotating groove 7 in the lifting plate 4, which facilitates the two spray cylinders 8 to reciprocate within the lifting plate 4.

[0023] Specifically, the transmission mechanism includes a transmission rod 14 and a transmission gear 15. One end of the transmission rod 14 is fixedly installed on the bottom side of the spray cylinder 8, and the other end of the transmission rod 14 extends movably into the first chamber 12 and is fixedly installed with the transmission gear 15. When the transmission gear 15 on the transmission rod 14 rotates, it can drive the spray cylinder 8 to rotate.

[0024] Specifically, the deflection adjustment drive mechanism includes a second motor 16 and a gear column 17. The second motor 16 is fixedly installed in the second chamber 13 of the mounting bracket 2. The output shaft of the second motor 16 extends rotatably into the first chamber 12 and is fixedly installed with the gear column 17. The gear column 17 meshes with two transmission gears 15. By starting the second motor 16, the gear column 17 is made to reciprocate at a certain angle. Since the gear column 17 meshes with the two transmission gears 15, it synchronously drives the two sets of transmission rods 14 and the spray cylinder 8 to reciprocate at an angle.

[0025] Specifically, each of the two spray cylinders 8 is connected to one end of a water supply hose 18, and the two water supply hoses 18 on the two spray cylinders 8 are connected together. The mounting bracket 2 has two side openings 19 respectively. Water is delivered to the two spray cylinders 8 through the water supply hoses 18 via an external water supply device.

[0026] In use: During dust suppression in open-pit coal mines, water is supplied via an external water supply device through a water supply hose 18 to two spray cylinders 8. The water is then sprayed out through multiple water nozzles 9 on the outer walls of the two spray cylinders 8, achieving dust suppression by spraying water on the open-pit coal mine. Simultaneously, by starting the second motor 16, the gear column 17 reciprocates at a certain angle. Since the gear column 17 meshes with two transmission gears 15, it synchronously drives the two sets of transmission rods 14 and the spray cylinders 8 to reciprocate at a 120-degree angle, thereby increasing the efficiency of the two spray cylinders. The multiple water spray heads 9 on the cylinder 8 cover the dust suppression area. Multiple rollers 11 on the two spray cylinders 8 roll on the inner wall of the corresponding rotating groove 7 inside the lifting plate 4, which facilitates the reciprocating rotation of the two spray cylinders 8 inside the lifting plate 4. At the same time, by starting the first motor 5, the threaded rod 6 can be driven to reciprocate, so that the lifting plate 4 can be reciprocated and adjusted in the lifting groove 3 of the mounting frame 2. Thus, the reciprocating lifting height adjustment of the two spray cylinders 8 on the lifting plate 4 can be realized simultaneously, which improves the working efficiency of the dust suppression device in the open-pit coal mine.
