Description

Technical Field

[0001] This utility model relates to the field of coal mining machine cutting tooth cleaning equipment, and more specifically, to a coal mining machine cutting tooth cleaning device. Background Technology

[0002] Coal mining machine cutting teeth are key components for cutting coal and rock, directly participating in the crushing and stripping of coal seams. Their performance directly affects the working efficiency, performance, and stability of the coal mining machine. However, during the process of cutting coal and rock, cutting teeth will accumulate impurities such as coal dust, rock slag, and mud. If they are not cleaned regularly, these impurities may cause uneven wear on the cutting teeth, reducing their service life.

[0003] Currently, when cleaning impurities adhering to the outer surface of cutting teeth, high-pressure water guns are generally used to rinse the impurities. When the high-pressure water gun sprays water at increased pressure onto the outer surface of the cutting teeth, the high-pressure water impacts the impurities, causing them to detach from the outer surface of the cutting teeth. This process cleans the outer surface of the cutting teeth. However, high-pressure water guns cannot completely remove coal slime and bituminous coal adhering to the outer surface of the cutting teeth (due to their strong adhesion). After the cutting teeth are rinsed with high-pressure water guns, cleaning tools (such as brushes and flat shovels) are needed to remove the coal slime and bituminous coal adhering to the outer surface of the cutting teeth. This increases the number of steps, time, and effort required for cleaning the outer surface of the cutting teeth, thus reducing the efficiency of the cleaning process.

[0004] Therefore, this utility model provides a coal mining machine cutting tooth cleaning device to solve the above problems. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0021] Example 1 This embodiment provides a coal mining machine cutting tooth cleaning device, such as... Figure 1As shown, it includes a cleaning section and a decontamination component. The cleaning section includes a mixing tank 3 and a water pump 2. The water inlet of the water pump 2 is connected to the bottom of the mixing tank 3, and the water outlet of the water pump 2 is connected to a water spray gun 4. The water spray gun 4 is used to clean the cutting teeth of the coal mining machine. The water spray gun 4 and the water pump 2 can be connected by a hose, which facilitates the operation of the water spray gun 4. The decontamination component is set at the nozzle of the water spray gun 4. The decontamination component removes dirt by striking the outer wall of the cutting teeth of the coal mining machine.

[0022] Specifically, the mixing tank 3 can fully stir and mix water and alkaline cleaning agents such as sodium hydroxide and sodium carbonate, and dilute the alkaline cleaning agents. The alkaline cleaning agents can dissolve the coal slime and bituminous coal adhering to the outer surface of the cutting teeth, thereby making the coal slime and bituminous coal adhering to the outer wall of the cutting teeth softer and easier to remove.

[0023] When in use, start the water pump 2, then hold the water gun 4 and aim the nozzle at the cutting teeth. Then press the switch of the water gun 4, so that the cleaning agent in the mixing tank 3 is transferred to the hose through the water pump 2 and then to the inside of the water gun 4. The cleaning agent inside the water gun 4 is sprayed onto the outer surface of the cutting teeth through the nozzle, which can wash away the coal powder, rock slag and mud adhering to the outer surface of the cutting teeth.

[0024] In this embodiment, as Figure 3 and Figure 5 As shown, the cleaning component includes a cleaning pipe 5, with an installation pipe 6 axially passing through it. The installation pipe 6 is connected to the nozzle of the water gun 4 at one end outside the inner cavity of the cleaning pipe 5. A connecting pipe 12 is rotatably installed at one end of the installation pipe 6 inside the inner cavity of the cleaning pipe 5. A support plate 11 is fixedly sleeved on the outer wall of the connecting pipe 12. Multiple cleaning plates 10 are arranged along the edge of the side of the support plate 11 away from the installation pipe 6. Cleaning bristles 9 are installed on the side of the cleaning plate 10 near the axis of the cleaning pipe 5. After the installation pipe 6 is connected to the water gun 4 and the cutting teeth need to be cleaned, the water gun 4 is held and moved towards the cutting teeth until one of the cutting teeth is inserted into the inner cavity of the cleaning pipe 5. At this time, the multiple rows of cleaning bristles 9 are in contact with the outer wall of the cutting teeth.

[0025] The connecting pipe 12 is also connected to a drive motor, which rotates the cleaning bristles 9 by rotating the connecting pipe 12. The drive motor is installed on the outer wall of the cleaning pipe 5. The output end of the drive motor is provided with a first tensioning wheel, and the outer wall of the connecting pipe 12 is provided with a second tensioning wheel. The first tensioning wheel and the second tensioning wheel are rotatably connected by a tensioning belt. The wall of the cleaning pipe 5 has a through hole for the tensioning belt to pass through. After the cutting tooth is inserted into the inner cavity of the cleaning pipe 5, the drive motor is started and the water spray gun 4 is switched on. At this time, the first tensioning wheel connected to the output end of the drive motor rotates, and the second tensioning wheel rotates under the action of the tension belt, which realizes the rotation of the bearing plate 11. When the bearing plate 11 rotates, the multiple cleaning plates 10 rotate accordingly. At this time, the rotating cleaning bristles 9 can beat the impurities (such as coal slime, bituminous coal, rock slag and mud, etc.) attached to the outer surface of the cutting tooth, and apply impact force to the impurities attached to the outer surface of the cutting tooth. At the same time, the high-pressure cleaning agent is sprayed directly onto the outer surface of the cutting tooth through the connecting pipe 12, thereby continuously rinsing the outer surface of the cutting tooth, removing the impurities attached to the outer surface of the cutting tooth, and cleaning the outer surface of the cutting tooth. This reduces the steps, time and effort required for cleaning the outer surface of the cutting tooth, and improves the efficiency of cleaning the outer surface of the cutting tooth.

[0026] In one embodiment of this example, as Figure 2 As shown, the mounting pipe 6 is detachably connected to the nozzle of the water spray gun 4. Preferably, the end of the mounting pipe 6 away from the connecting pipe 12 has an internal thread, and the nozzle of the water spray gun 4 has an external thread corresponding to the internal thread. Before cleaning coal dust, rock slag, and mud from the outer surface of the cutting teeth, the nozzle of the water spray gun 4 is threadedly connected to the mounting pipe 6. At this time, the nozzle is completely located in the inner cavity of the mounting pipe 6. When the high-pressure cleaning agent is sprayed from the nozzle, the mounting pipe 6 and the cleaning pipe 5 can reduce the area sprayed by the nozzle, allowing the sprayed cleaning agent to act completely on the outer wall of the cutting teeth. When it is necessary to spray the entire coal-mining end of the coal mining machine with cleaning agent, it is necessary to increase the spraying area of ​​the cleaning agent. In this case, the mounting pipe 6 and the water spray gun 4 can be detached.

[0027] In another embodiment of this invention, a sealed bearing is provided on the inner wall of the connecting pipe 12, and the inner ring of the sealed bearing is fixedly connected to the outer wall of the mounting pipe 6. The sealed bearing enables the connecting pipe 12 to rotate with the mounting pipe 6, allowing the connecting pipe 12 to rotate under the drive of the second tensioning wheel, thereby improving the stability of the rotation of the connecting pipe 12.

[0028] Furthermore, in this embodiment, such as Figures 3-5As shown, a support ring 8 is rotatably installed inside the cleaning pipe 5. The support ring 8 is fixedly connected to the end of multiple cleaning plates 10 away from the support plate 11. Multiple limiting balls 7 are provided on the outer wall of the support ring 8, and all the limiting balls 7 are in contact with the inner wall of the mounting pipe 6. When the multiple cleaning plates 10 rotate with the support plate 11, the support ring 8 rotates accordingly, thereby increasing the strength of the cleaning plates 10 and extending their service life. Specifically, when the support ring 8 rotates, the outer wall of the limiting balls 7 continuously rotates under the action of the inner wall of the cleaning pipe 5, thus supporting the rotating support ring 8 and improving the stability of its rotation.

[0029] In the above embodiment, the cleaning bristles 9 are made of steel wire. The flexible steel wire material increases the strength of the cleaning bristles 9 and the impact force exerted on the impurities on the outer wall of the cutting teeth, making it easier for impurities attached to the outer wall of the metal steel wire to fall off.

[0030] For ease of movement in this embodiment, such as Figure 1 As shown, the cleaning unit is located on the trolley 1; it is moved by the trolley 1; the trolley 1 allows the mixing box 3 to be moved, which is beneficial for pushing the mixing box 3 to the side of the cutting teeth of the coal mining machine, so as to facilitate the cleaning of the cutting teeth.

[0031] In summary, the embodiments of this utility model provide a coal mining machine cutting tooth cleaning device, which has at least the following advantages or beneficial effects: In this invention, the cleaning component can beat the impurities attached to the outer surface of the cutting teeth, applying impact force to the impurities. At the same time, the cleaning agent in the mixing tank 3 is directly sprayed onto the outer surface of the cutting teeth through the connecting pipe 12, thereby continuously rinsing the outer surface of the cutting teeth, removing the impurities attached to the outer surface of the cutting teeth, and cleaning the outer surface of the cutting teeth. This reduces the steps, time and effort required for cleaning the outer surface of the cutting teeth, and improves the efficiency of cleaning the outer surface of the cutting teeth.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
