Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, specifically to a green dust removal device for coal mining. Background Technology

[0002] A coal mine refers to a place rich in coal resources, generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, underground tunnels are typically dug to extract the coal; this is called an underground coal mine. When the coal seam is very close to the surface, the surface soil is typically stripped away to extract the coal; this is called an open-pit coal mine. Coal is the most important solid fuel, a type of combustible organic rock. Based on the degree of coalification, it can be divided into four categories: peat, lignite, bituminous coal, and anthracite.

[0003] Application number CN202122081575.9 discloses a green and environmentally friendly dust removal device for coal mines. The height of the atomizing nozzle is easily adjustable without the need for motors or other mechanical drives, reducing energy consumption and making it more environmentally friendly. Furthermore, the height can be adjusted according to actual needs, making it suitable for dust suppression operations in coal mines at different heights, thus enhancing its practicality. However, the above design still has shortcomings. The device uses locking casters to fix its position, but once locked, its overall orientation cannot be flexibly adjusted. This limits the device's application range in specific operating scenarios and makes it difficult to fully adapt to the complex and ever-changing dust suppression needs of coal mines.

[0004] Therefore, we propose a green dust removal device for coal mining. Utility Model Content

[0005] The main purpose of this utility model is to provide a green dust removal device for coal mining. By setting a motor, a rotating shaft and ball bearings, the motor can drive the support to rotate relative to the base, thereby adjusting the orientation of the dust removal components. This allows the device to flexibly adjust the dust removal direction even after the position is fixed, which can fully adapt to the complex and ever-changing dust reduction needs in coal mines, effectively expand the scope of application of the device, and effectively solve the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A green dust removal device for coal mining includes a base, an adjustment mechanism, and a support assembly. The upper end face of the base is equipped with a dust removal assembly, and the lower end face of the base has a mounting groove for installing the adjustment mechanism at its center. The lower end face of the base has positioning grooves for installing the support assembly at both ends. Two sets of support assemblies are arranged opposite each other, and the adjustment mechanism is located between the two sets of support assemblies.

[0008] The adjustment mechanism includes a support base, an electric cylinder, a buckle plate, a motor, a rotating shaft, ball bearings, a positioning plate, a locking tooth, a heat-conducting plate, a heat dissipation plate, a second moving wheel, and a protrusion. The support base is a circular plate structure. Multiple sets of relatively parallel second moving wheels are installed on the lower end face of the support base. The support base also has a cavity for installing the electric cylinder. The bottom end of the support base, below the cavity, has a storage groove for storing the positioning plate.

[0009] The support assembly includes an assembly plate, a first bolt, support legs, and a first movable wheel. The upper surface of the assembly plate is fastened in a positioning groove, and multiple support legs arranged in parallel are vertically inserted into the lower surface of the assembly plate. The bottom end of each support leg is equipped with a first movable wheel.

[0010] By adopting the above technical solution, and by setting up a motor, a rotating shaft and ball bearings, the motor can drive the support to rotate relative to the base, thereby adjusting the orientation of the dust removal components. This allows the device to flexibly adjust the dust removal direction even after the position is fixed, which can fully adapt to the complex and ever-changing dust reduction needs in coal mines and effectively expand the scope of application of the device.

[0011] Specifically, the top of the first bolt passes through the assembly plate and is threaded to the lower end face of the base, and the bottom ends of the first and second moving wheels are located on the same horizontal line.

[0012] Specifically, the support base has an internal mounting cavity for mounting a motor. The output shaft at the top of the motor is connected to the bottom of the rotating shaft via a coupling. The top of the rotating shaft passes through the inner wall of the top of the mounting cavity and is vertically inserted into the inner wall of the top of the mounting groove. Ball bearings are also provided between the top of the support base and the inner wall of the top of the mounting groove.

[0013] The bottom end of the support base is fastened with a buckle plate located at the position of the mounting cavity, and the upper surface of the buckle plate is provided with a protrusion located in the mounting cavity.

[0014] Specifically, a heat-conducting plate is embedded in the center of the upper surface of the protrusion, and multiple heat dissipation plates arranged in parallel are vertically welded to the lower surface of the heat-conducting plate. The inside of the buckle plate is provided with a heat-conducting cavity for accommodating the heat dissipation plates.

[0015] Specifically, both ends of the buckle plate are fixedly connected to the bottom of the support base by a second bolt, and a heat dissipation port communicating with the heat conduction cavity is provided in the center of the lower end face of the buckle plate.

[0016] Specifically, the bottom end of the electric cylinder is connected to the top end of the positioning plate via a piston rod, and the lower end face of the positioning plate is provided with locking teeth.

[0017] The beneficial effects of this utility model are as follows: The green dust removal device for coal mining described in this utility model, by setting up a motor, a rotating shaft, and ball bearings, allows the motor to drive the support base to rotate relative to the base, thereby adjusting the orientation of the dust removal components. This allows the device to flexibly adjust the dust removal direction even after the position is fixed, fully adapting to the complex and ever-changing dust reduction needs in coal mines and effectively expanding the scope of application of the device. The electric cylinder pushes the positioning plate with locking teeth to embed into the ground. The meshing action of the locking teeth with the ground significantly enhances the connection strength between the device and the ground, avoiding the risk of slippage in a vibrating environment and improving the stability and safety during dust removal operations. The heat dissipation structure, composed of a heat-conducting plate, a heat-dissipating plate, a heat-conducting cavity, and a heat dissipation port, can quickly conduct and dissipate the heat generated by the motor to the outside, effectively controlling the motor's operating temperature, preventing damage due to overheating, and extending the service life of the motor and the entire device. The support components are detachably connected to the base via a first bolt, and the buckle plate is detachably connected to the support base via a second bolt, making the inspection and replacement of the support components and motor more convenient and reducing maintenance time and costs.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As one embodiment of this utility model, such as Figures 1-3As shown, the green dust removal device for coal mining of this utility model includes a base 1, an adjustment mechanism 3, and a support assembly 10. The upper end face of the base 1 is equipped with a dust removal assembly, and the lower end face of the base 1 is provided with an installation groove 2 for installing the adjustment mechanism 3 at the center. The lower end face of the base 1 is provided with positioning grooves 9 at both ends for installing the support assembly 10. Two sets of support assemblies 10 are arranged opposite each other, and the adjustment mechanism 3 is located between the two sets of support assemblies 10.

[0025] The adjustment mechanism 3 includes a support base 4, an electric cylinder 6, a buckle plate 7, a motor 15, a rotating shaft 16, a ball bearing 17, a positioning plate 18, a locking tooth 19, a heat-conducting plate 20, a heat dissipation plate 22, a second moving wheel 23, and a protrusion 24. The support base 4 is a circular plate structure. Multiple sets of relatively parallel second moving wheels 23 are installed on the lower end face of the support base 4. The support base 4 also has a cavity 5 for installing the electric cylinder 6. The bottom end of the support base 4 is located below the cavity 5 and has a storage groove 8 for storing the positioning plate 18.

[0026] The support assembly 10 includes an assembly plate 11, a first bolt 12, support legs 13 and a first moving wheel 14. The upper end face of the assembly plate 11 is fastened in the positioning groove 9, and multiple support legs 13 arranged in parallel are vertically inserted into the lower end face of the assembly plate 11. The first moving wheel 14 is installed at the bottom end of the support legs 13.

[0027] In use, the operator can push the base 1 and use the rolling action of the first moving wheel 14 and the second moving wheel 23 to move the entire device to the target dust removal position in the coal mine. When the device reaches the designated position, the electric cylinder 6 pushes the positioning plate 18 downward through the piston rod at the bottom until the locking teeth 19 on the lower end of the positioning plate 18 are tightly embedded in the ground to prevent the device from sliding during operation. When it is necessary to adjust the orientation of the dust removal device, the output shaft at the top of the motor 15 located in the mounting cavity 25 in the support base 4 drives the rotating shaft 16 to rotate through the coupling. Since the top of the rotating shaft 16 is vertically inserted into the inner wall of the top of the mounting groove 2 on the lower end of the base 1, and there are ball bearings 17 between the top of the support base 4 and the inner wall of the top of the mounting groove 2, the ball bearings 17 can reduce the frictional resistance between the two, so that the motor 15 can drive the support base 4 to rotate flexibly relative to the base 1, thereby driving the dust removal components on the upper end of the base 1 to adjust their orientation until the dust removal device is adjusted to the designated orientation.

[0028] The present invention also includes that the top end of the first bolt 12 passes through the assembly plate 11 and is threadedly connected to the lower end face of the base 1, and the bottom end of the first movable wheel 14 and the bottom end of the second movable wheel 23 are located on the same horizontal line.

[0029] The present invention also includes that the support base 4 is provided with a mounting cavity 25 for mounting the motor 15, the output shaft at the top of the motor 15 is connected to the bottom end of the rotating shaft 16 through a coupling, the top end of the rotating shaft 16 passes through the inner wall of the top end of the mounting cavity 25 and is vertically inserted into the inner wall of the top end of the mounting groove 2, and a ball bearing 17 is also provided between the top end of the support base 4 and the inner wall of the top end of the mounting groove 2.

[0030] The bottom end of the support base 4 is fastened with a buckle plate 7 at the location of the mounting cavity 25, and the upper surface of the buckle plate 7 is provided with a protrusion 24 located in the mounting cavity 25.

[0031] The present invention also includes a heat-conducting plate 20 embedded in the center of the upper surface of the protrusion 24, and a number of relatively parallel heat dissipation plates 22 vertically welded to the lower surface of the heat-conducting plate 20. The buckle plate 7 is provided with a heat-conducting cavity 21 for accommodating the heat dissipation plates 22.

[0032] The present invention also includes that both ends of the buckle plate 7 are fixedly connected to the bottom end of the support base 4 by second bolts, and a heat dissipation port 26 communicating with the heat conduction cavity 21 is provided at the center of the lower end surface of the buckle plate 7.

[0033] This utility model also includes that the bottom end of the electric cylinder 6 is connected to the top end of the positioning plate 18 through a piston rod, and the lower end face of the positioning plate 18 is provided with a locking tooth 19.

[0034] In use, this invention first aligns the bottom of the first moving wheel 14 in the support assembly 10 with the bottom of the second moving wheel 23 in the adjustment mechanism 3 at the same horizontal level. The positioning plate 18 is housed in the storage groove 8 at the bottom of the support base 4, and the locking teeth 19 are not in contact with the ground. Workers can move the entire device to the target dust suppression position in the coal mine by pushing the base 1, utilizing the rolling action of the first moving wheel 14 and the second moving wheel 23. Once the device reaches the designated position, the electric cylinder 6 pushes the positioning plate 18 downwards via the piston rod at its bottom until the locking teeth 19 on the lower surface of the positioning plate 18 are firmly embedded in the ground. To prevent the device from sliding during operation; when the orientation of the dust removal device needs to be adjusted, the output shaft at the top of the motor 15 located in the mounting cavity 25 of the support base 4 drives the rotating shaft 16 to rotate through the coupling. Since the top of the rotating shaft 16 is vertically inserted into the inner wall of the top of the mounting groove 2 on the lower end face of the base 1, and there are ball bearings 17 between the top of the support base 4 and the inner wall of the top of the mounting groove 2, the ball bearings 17 can reduce the frictional resistance between the two, so that the motor 15 can drive the support base 4 to rotate flexibly relative to the base 1, thereby driving the dust removal components on the upper end face of the base 1 to adjust their orientation until the dust removal device is adjusted to the specified orientation;

[0035] During the operation of the motor 15, the heat generated is conducted through the heat-conducting plate 20 on the upper end face of the protrusion 24 to the heat dissipation plate 22 on the lower end face of the heat-conducting plate 20. The heat dissipation plate 22 is located in the heat-conducting cavity 21 inside the buckle plate 7, and the lower end face of the buckle plate 7 is provided with a heat dissipation port 26 that communicates with the heat-conducting cavity 21. The heat is diffused into the heat-conducting cavity 21 through the heat dissipation plate 22, and then dissipated to the outside through the heat dissipation port 26, thereby achieving efficient heat dissipation of the motor 15.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
