Description

Technical Field

[0001] The utility model relates to the technical field of coal tipping, in particular to a coal tipping device. Background Technique

[0002] As is well known, in the process of coal processing, coal blocks need to be crushed, washed and other steps. Only after the coal blocks with certain dimensions and characteristics after processing can meet the production requirements. After the coal blocks are transported out of the coal mine, they need to be transferred in a relatively large site, and small carts are often needed to transfer the coal during the transfer process.

[0003] The patent with the application number CN202321273465.5 discloses a coal tipping device, including a mounting plate, a connecting seat, a support rod, a tipping mechanism, a connecting plate, a connecting rod, a connecting ring and a driving mechanism. Two connecting seats are symmetrically and fixedly connected to the upper surface of the right end of the mounting plate. The upper end of the connecting seat is fixedly connected with a support rod. The tipping mechanism includes a connecting shaft, a hopper, a support seat, a rotating shaft, a winding drum and a steel cable. The two ends of the connecting shaft are respectively rotatably connected to the upper ends of the two support rods. The upper end of the right side of the hopper is movably connected to the connecting shaft. A connecting plate is fixedly connected to the outer surface at the middle position on the right side of the hopper. Connecting rods are respectively and fixedly connected to the front and back surfaces of the connecting plate. Connecting rings are respectively rotatably connected to the connecting rods.

[0004] Although this device has the effect of shaking off the coal powder on the inner wall of the storage box, this device drives the shaking plate to vibrate by the rotation of the motor to shake off the coal powder. For some coal powder with strong adsorption force or when there is more coal powder adsorbed on the inner wall of the storage box, the effect of shaking off the coal powder by this vibrating method is not very good. For some coal powder attached to the surface layer of the inner wall of the storage box, it is often impossible to completely shake it off, and the cleaning effect is not very good. It requires the staff to scrape off the surface coal powder again. Therefore, the practicality of this device is not very good and there is room for improvement. Content of the Utility Model

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5, A coal dumping device of the present utility model includes a base 1. The left part of the base 1 is rotatably connected to a hydraulic cylinder 2 through a fourth rotating shaft. The hydraulic cylinder 2 rotates left and right on the base 1 through the fourth rotating shaft. The upper part of the hydraulic cylinder 2 is provided with a connecting rod 3. Both the front and rear ends of the connecting rod 3 are rotatably connected to a first fixing plate 4 through a first rotating shaft. The upper parts of several first fixing plates 4 are provided with a storage box 5. After the coal is added to the storage box 5, the hydraulic cylinder 2 is started. The hydraulic cylinder 2 extends, driving the connecting rod 3 to move and rotate circumferentially during the movement. At this time, the connecting rod 3 drives the first fixing plate 4 to rotate through the first rotating shaft, and drives the storage box 5 to rotate to pour out the internal coal. The left part of the base 1 is provided with several second support plates 16. The upper end surfaces of several second support plates 16 are all in contact with the lower end surfaces of the corresponding first fixing plates 4. When adding coal to the storage box 5, the lower part of the first fixing plate 4 is supported on the upper part of the second support plate 16, and the second support plate 16 plays a supporting role. The lower part of the right part of the storage box 5 is provided with several third fixing plates 13 and is rotatably connected to a first support plate 14 through a third rotating shaft. The lower part of the first support plate 14 is connected to the right part of the base 1. The first support plate 14 supports the storage box 5. When the storage box 5 dumps coal during rotation, the first support plate 14 rotates relative to the third fixing plate 13 through the fourth rotating shaft. The middle part of the storage box 5 is rotatably connected to a scraper 6 through several second rotating shafts. A motor 7 is installed in front of the second rotating shaft located in the front. After the coal in the storage box 5 is dumped, the motor 7 is started. The motor 7 rotates, driving the scraper 6 to rotate, and scraping off all the pulverized coal adhering to the inner wall of the storage box 5, avoiding the pulverized coal adhering to the inner wall of the storage box 5. The left part of the storage box 5 is provided with several through holes 8, and all are penetrated and connected with drain pipes 9. During the coal dumping period, the water mist discharged from the drain pipes 9 adheres to the moving coal, avoiding the occurrence of dust. Several drain pipes 9 are all flexible hoses. The flexibility of the hoses is good. When the storage pipe rotates, the drain pipes 9 can move together without being damaged. There is a gap between one end of several drain pipes 9 and the scraper 6, preventing the scraper 6 from rubbing against the drain pipes 9 during rotation. The lower part of several drain pipes 9 is provided with a connecting pipe 10. The middle part of the connecting pipe 10 is penetrated and connected with a water tank 11. The left part of the water tank 11 is provided with a liquid inlet pipe 15 and is threadedly connected with a cover. Unscrew the cover and add water to the water tank 11 through the liquid inlet pipe 15. A water pump 12 is installed at the lower part of the connecting pipe 10. Start the water pump 12. The water pump 12 discharges the water in the water tank 11 into the connecting pipe 10 and enters the drain pipes 9, and finally sprays on the coal to prevent the occurrence of dust. The diameters of several through holes 8 are all smaller than the upper and lower lengths of the scraper 6, facilitating the scraper 6 to block the through holes 8. One side end face of the scraper 6 is in contact with the inner wall of the storage box 5, facilitating the scraper 6 to scrape off the pulverized coal on the surface of the storage box 5.

[0025] In summary, when using this coal tipping device, after the staff adds coal into the storage bin 5, the hydraulic cylinder 2 is started. The hydraulic cylinder 2 extends and drives the connecting rod 3 to move. At this time, the lower part of the hydraulic cylinder 2 rubs against the base 1 through the fourth rotating shaft, and the connecting rod 3 rotates through the first rotating shaft and the first fixing plate 4. Then the storage bin 5 rotates upward to the right. At the same time, the second fixing plate rotates on the first support plate 14 through the third rotating shaft, and the coal in the storage bin 5 falls outward. At the same time, the motor 7 is started in the forward direction. The motor 7 rotates and drives the scraper 6 to rotate. As the coal in the storage bin 5 decreases, the scraper 6 scrapes the pulverized coal adhering to the inner wall of the storage bin 5. At this time, the scraper 6 leaves the through hole 8, and the water pump 12 is started. The water pump 12 discharges the water in the water tank 11 into the connecting pipe 10 and enters the drain pipe 9, and finally sprays on the coal to avoid dust. When the tipping is completed, the hydraulic cylinder 2 is started. The hydraulic cylinder 2 contracts and drives the connecting rod 3 to move backward to the original position. At this time, the lower part of the first fixing plate 4 supports on the upper part of the second support plate 16. Then the motor 7 is started in the reverse direction. The motor 7 drives the scraper 6 to rotate in the reverse direction. When the scraper 6 blocks the through hole 8, the motor 7 can be turned off.
