Description

Technical Field

[0001] This utility model relates to the field of coal mine machinery and equipment cleaning technology, specifically a coal mining machinery cleaning mechanism. Background Technology

[0002] In the coal mining process, mining machinery is the core equipment, and its performance stability and reliability are directly related to the production efficiency and safety of the coal mine. However, due to the complex mining environment, mining machinery often gets contaminated with a large amount of coal dust, mud, rock debris and other impurities during operation. These impurities not only affect the normal operation of the machinery, but may also accelerate the wear of mechanical parts and shorten the service life of the equipment.

[0003] Currently, most coal mining machinery is cleaned using traditional manual rinsing or simple fixed nozzle rinsing. This method has blind spots, some areas are difficult to reach, and it cannot thoroughly clean the dirt on the machinery. Furthermore, it is inefficient and consumes a significant amount of time, manpower, and resources. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to provide a cleaning mechanism for coal mining machinery, which solves the problem that traditional cleaning methods mentioned in the background technology mostly use traditional manual rinsing or simple fixed nozzle rinsing. These methods have cleaning dead corners, some areas are difficult to reach, and cannot thoroughly clean the dirt on the mining machinery.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cleaning mechanism for coal mining machinery, comprising a cleaning cylinder, wherein a rotating tube is passed through the center of the outer side wall of the cleaning cylinder, and the rotating tube is rotatably connected to the cleaning cylinder through a bearing seat; a plurality of flushing tubes are fixedly connected in a circumferential array on the outer surface of one end of the rotating tube located inside the cleaning cylinder, and the flushing tubes are connected to the rotating tube.

[0006] In this technical solution, the rotating tube rotates, driving several flushing tubes to surround and flush the instrument, thereby flushing all parts and dead corners of the instrument. Compared with traditional manual flushing, the surrounding flushing method is faster, saves time and effort, and has higher cleaning efficiency.

[0007] Preferably, a fixing frame is fixedly connected to the outer surface of the cleaning cylinder above the rotating tube, a servo motor is fixedly connected to the outer surface of the fixing frame, a gear is rotatably connected to the inner surface of the fixing frame on the opposite side of the servo motor, and the tail end of the drive shaft of the servo motor is fixedly connected to the gear.

[0008] Preferably, a circular groove is formed on the outer surface of the cleaning cylinder above the fixing frame, a rotating ring is rotatably connected to the inner side of the circular groove, a crossbar is fixedly connected to the inner side wall of the rotating ring, and a fan blade is fixedly connected to the surface of the crossbar.

[0009] Preferably, the outer surface of the rotating tube is fixedly connected with a plurality of first protruding teeth in a circumferential array, the first protruding teeth meshing with gears, and the water inlet end of the rotating tube is rotatably connected to a water inlet pipe.

[0010] Preferably, the outer wall of the rotating ring is fixedly connected with a plurality of second-order convex teeth in a circumferential array, the second-order convex teeth meshing with gears, and an intercepting net is fixedly connected to the opening of the rotating ring facing the inside of the cleaning cylinder.

[0011] Preferably, the bottom of the cleaning cylinder is connected to a water receiving tank, and a support ring is rotatably connected to the inner side of the annular groove at the opening of the inner wall of the cleaning cylinder, and the support ring is fixedly connected to the rinsing pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model has several rinsing pipes installed inside the cleaning cylinder. After the instrument is inserted into the cleaning cylinder, the rotating pipe rotates, causing the several rinsing pipes to circulate and rinse the instrument, thereby rinsing all parts and dead corners of the instrument. Compared with traditional manual rinsing, the circumferential rinsing method is faster, saves time and effort, and has higher cleaning efficiency.

[0014] 2. This utility model uses gears to simultaneously drive the rotating tube and the rotating ring to rotate. The rotating tube achieves circumferential rinsing during rotation, while the rotating ring drives the fan blades to rotate, generating a certain airflow. This draws out the floating water vapor inside the cleaning tube, and the intercepting net intercepts the mud and dust, reducing the amount of mud and dust that drifts into the air with the water vapor, thus improving the protection of the surrounding air and environment.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0022] A cleaning mechanism for coal mining machinery, see [link / reference] Figures 1 to 4 The system includes a cleaning cylinder 1, with a rotating tube 2 penetrating through the center of its outer wall. The inlet end of the rotating tube 2 is rotatably connected to an inlet pipe 201, the other end of which is connected to an external water pump to draw in flushing water. A sealing ring is provided at the rotating contact point between the inlet pipe 201 and the rotating tube 2 to reduce leakage. The rotating tube 2 is rotatably connected to the cleaning cylinder 1 via a bearing seat. The outer surface of the rotating tube 2 is fixedly connected to the inner ring of the bearing seat, and the outer ring of the bearing seat is fixedly connected to the inner wall of the cleaning cylinder 1, ensuring normal rotation without detachment. Several flushing pipes 3 are fixedly connected in a circular array on the outer surface of one end of the rotating tube 2 inside the cleaning cylinder 1. The flushing pipes 3 are connected to the rotating tube 2. When the rotating tube 2 rotates, the flushing pipes 3 rotate under its influence, thus circumferentially flushing the instruments inserted into the cleaning cylinder 1, cleaning various locations and hard-to-reach areas, improving cleaning efficiency compared to manual cleaning.

[0023] Specifically, such as Figure 2 As shown, a fixed frame 6 is fixedly connected to the outer surface of the cleaning cylinder 1 above the rotating tube 2. A servo motor 7 is fixedly connected to the outer surface of the fixed frame 6. A gear 701 is rotatably connected to the inner surface of the fixed frame 6 on the opposite side of the servo motor 7. The tail end of the drive shaft of the servo motor 7 is fixedly connected to the gear 701. After the servo motor 7 is started, it drives the gear 701 to rotate. During the rotation of the gear 701, the rotating tube 2 and the rotating ring 9 will rotate. The servo motor 7 is equipped with a waterproof shell to prevent water from getting into it during the extraction of water vapor and causing damage.

[0024] Furthermore, such as Figure 2 and Figure 4As shown, the outer surface of the rotating tube 2 is fixedly connected with several first protruding teeth 202 in a circumferential array. The first protruding teeth 202 mesh with the gear 701. The outer wall of the rotating ring 9 is fixedly connected with several second protruding teeth 901 in a circumferential array. The second protruding teeth 901 mesh with the gear 701. When the gear 701 rotates, it drives the first protruding teeth 202 and the rotating tube 2 to rotate. It also drives the rotating ring 9 above to rotate through the second protruding teeth 901. Thus, the ventilation and circumferential rinsing operations are realized at the same time. There is no need to set up two sets of drive devices, which saves costs.

[0025] It is worth noting that, such as Figure 2 and Figure 3 As shown, a circular groove 8 is provided on the outer surface of the cleaning cylinder 1 above the fixing frame 6. A rotating ring 9 is rotatably connected to the inner side of the circular groove 8. A crossbar 10 is fixedly connected to the inner wall of the rotating ring 9. A fan blade 11 is fixedly connected to the surface of the crossbar 10. An intercepting net 12 is fixedly connected to the opening of the rotating ring 9 facing the inner side of the cleaning cylinder 1. When the rotating ring 9 rotates, the fan blade 11 will generate a suction effect to extract the water vapor inside the cleaning cylinder 1 and intercept and filter out the floating mud and dust to prevent a large amount from drifting out and affecting the surrounding environment.

[0026] It is worth noting that, such as Figure 1 and Figure 3 As shown, the bottom of the cleaning cylinder 1 is connected to a water receiving tank 5, which can collect most of the rinsing water and then collect and filter it in a unified manner, thereby realizing the secondary use of water resources. The inner side of the annular groove 401 at the opening of the inner wall of the cleaning cylinder 1 is rotatably connected to a support ring 4. The support ring 4 is fixedly connected to the rinsing pipe 3. The support ring 4 can provide stable support for the rinsing pipe 3, thereby improving the stability of the rinsing pipe 3 and reducing the shaking caused by centrifugal force.

[0027] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

[0028] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
