Description

Technical Field

[0001] The utility model relates to the technical field of scraper conveyors, in particular to a high-efficiency scraper conveyor. Background Art

[0002] A conveyor that uses scraper chains to transport bulk materials in a trough is called a scraper conveyor. A KS scraper conveyor whose adjacent middle troughs can bend to a limited extent in the horizontal and vertical planes is called a flexible scraper conveyor. Among them, a working face conveyor with a body bent 90 degrees at the intersection of the working face and the transport tunnel is called a "corner scraper conveyor." In the current coal mining working face, the role of the scraper conveyor is not only to transport coal and materials, but also to serve as the operating track for the coal mining machine. Therefore, it has become an indispensable main equipment in the modern coal mining process.

[0003] After the existing scraper conveyor is started by the motor, the scrapers continuously transport the materials along the track under the rotation of each sprocket and the transmission of the chain. Due to the continuous feeding, the materials can be transported efficiently. However, the materials are not completely dry, which makes the materials have a certain stickiness. As the materials are transported to the top by the scrapers, part of the materials that contact the scrapers will stick to the scrapers, which may cause material accumulation on the scrapers. In order to clean the scrapers, an efficient scraper conveyor is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a high-efficiency scraper conveyor, which has the advantage of being easy to clean the scraper.

[0006] The beating assembly includes a movable shaft, a synchronous wheel, a synchronous belt, a connecting plate, a movable plate and a spring. The movable shaft is rotatably connected to the front wall and the rear wall of the discharge pipe. The synchronous wheel is fixedly installed on the end of the rotating shaft and the movable shaft. The synchronous belt is transmission-connected to the outer surface of the synchronous wheel. The connecting plate is fixedly connected to the outer surface of the movable shaft. The movable plate is slidably connected in the connecting plate. The spring is fixedly installed on the inner wall of the connecting plate and fixedly installed with the movable plate.

[0007] Furthermore, the extension shell is connected to the bottom shell and the discharge pipe, the rotating shaft is rotatably connected to the extension shell, and the connecting plate and the movable plate are both located in the discharge pipe.

[0008] Furthermore, a receiving groove is provided on the connecting plate, the spring is located in the receiving groove, and both ends of the movable plate are fixedly connected with stoppers corresponding to the connecting plate.

[0009] Furthermore, a mounting hole is provided on the bottom plate of the mounting frame, and a feed hopper communicating with the inner cavity of the bottom shell is fixedly mounted on the top wall of the bottom shell.

[0010] Furthermore, a driven shaft is rotatably connected between the front side wall and the opposite side of the rear side wall of the bottom shell, and the front wall and the rear wall of the bottom shell are both rotatably connected to a guide shaft.

The flapping assembly 8 includes a movable shaft 81, a synchronous wheel 82, a synchronous belt 83, a connecting plate 84, a movable plate 85 and a spring 86. The movable shaft 81 is rotatably connected to the front wall and the rear wall of the discharge pipe 4. The synchronous wheel 82 is fixedly mounted on the end of the rotating shaft 7 and the movable shaft 81. The synchronous belt 83 is transmission-connected to the outer surface of the synchronous wheel 82. Under the transmission of the synchronous wheel 82 and the synchronous belt 83, the rotating shaft 7 can drive the movable shaft 81 to rotate together. The connecting plate 84 is fixedly connected to the outer surface of the movable shaft 81 and can rotate with the movable shaft 81. The connecting plate 84 is provided with a accommodating groove 9.

[0023] In addition, the movable plate 85 is slidably connected to the connecting plate 84, and the movable plate 85 can move in the connecting plate 84. The connecting plate 84 and the movable plate 85 are both located in the discharge pipe 4. Both ends of the movable plate 85 are fixedly connected with a stopper 10 corresponding to the connecting plate 84, which prevents the movable plate 85 from completely moving out of the connecting plate 84 and plays a limiting role. The end of the movable plate 85 is arc-shaped, and the spring 86 is fixedly mounted on the inner wall of the connecting plate 84 and fixedly mounted with the movable plate 85. Under the elastic force of the spring 86, the movable plate 85 can repeatedly extend out of the connecting plate 84, thereby continuously slapping the moving scraper 17, effectively shaking off the material attached to the scraper 17, and the spring 86 is located in the accommodating groove 9.

[0024] See also Figure 1 、 Figure 2 and Figure 4 A driven shaft 13 is rotatably connected between the front side wall and the opposite side of the rear side wall of the bottom shell 2, and the front wall and the rear wall of the bottom shell 2 are rotatably connected to the guide shaft 14. The outer surfaces of the rotating shaft 7 and the driven shaft 13 and the end of the guide shaft 14 are fixedly installed with a sprocket 15, and the outer surface of the sprocket 15 is transmission-connected with a chain 16. Under the connection between the chain 16 and each sprocket 15, the scraper 17 can be driven by the rotating shaft 7 to carry out material conveying work. The sprocket 15 on the guide shaft 14 can guide the chain 16 and can convey the material according to the trajectory of the bottom shell 2 and the extension shell 3. A scraper 17 is installed between the opposite sides of the front and rear chains 16 for scraping the material on the bottom wall of the bottom shell 2. The movable plate 85 contacts the scraper 17, and the rotating movable plate 85 can slap the moving scraper 17 so that the material attached to the scraper 17 can be effectively shaken off and discharged.

[0025] When this embodiment is in use, the motor 6 is started and the rotating shaft 7 rotates. Under the rotation of the sprocket 15, the transmission chain 16 drives the scraper 17 to transport the material along the trajectory of the bottom shell 2 and the extension shell 3. Under the transmission of the synchronous wheel 82 and the synchronous belt 83, the connecting plate 84, the spring 86 and the movable plate 85 rotate. The rotating movable plate 85 slaps the moving scraper 17, causing the scraper 17 to vibrate, which can slap the material attached to the scraper 17 and discharge it from the discharge pipe 4.

[0026] The beneficial effects of the above embodiment are:

[0027] The efficient scraper conveyor is provided with a flapping assembly 8. After the flapping assembly 8 is used, the movable shaft 81, the connecting plate 84 and the movable plate 85 rotate under the drive of the synchronous wheel 82 and the synchronous belt 83, so that the rotating movable plate 85 can flap the continuously moving scraper 17, allowing the scraper 17 to drop the attached materials after vibration. At the same time, under the elastic force of the spring 86, the movable plate 85 can repeatedly extend to flap the continuous scraper 17, effectively cleaning the materials attached to the scraper 17 and avoiding the accumulation of materials on the scraper 17 as much as possible. At the same time, only one motor 6 is configured to realize the material transportation and the cleaning of the scraper 17, which is energy-saving and efficient.
