When the cleaner is in use, the cleaner will fall off the belt due to the vibration of the belt. Moreover, during daily use of the scraper, the automatic blanking and cleaning effect of the impurities after the scraper cleaning is not high, resulting in the accumulation of impurities on the surface of the scraper, affecting the subsequent cleaning effect and efficiency of the impurities on the belt surface.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a belt conveyor with a self-cleaning function is proposed. Content of the Utility Model

The outer wall of the legs 14 is rotatably connected with a supporting roller 15 that fits the bottom of the conveyor belt 12. The outer wall of the frame 1 is fixedly connected with a chute 17 on one side of the head frame 16. The outer wall of the head frame 16 is fixedly connected with a fixing frame 2. The outer wall of the fixing frame 2 is slidably connected with a sweeper 21 that fits the surface of the conveyor belt 12. A chute 22 is opened at the connecting part between the outer wall of the fixing frame 2 and the sweeper 21. The bottom of the sweeper 21 is fixedly connected with a telescopic rod 23 that is fixedly connected with the outer wall of the fixing frame 2. The outer wall of the sweeper 21 is fixedly connected with a spring 24 sleeved on the outer wall of the telescopic rod 23.

[0023] Furthermore, both the telescopic rod 23 and the spring 24 are provided in three groups. The three groups of telescopic rods 23 and springs 24 are arranged in a "one" shape at the bottom of the sweeper 21, which is beneficial to improving the effective earthquake resistance of the sweeper 21 by arranging the three groups of telescopic rods 23 and springs 24 in a "one" shape at the bottom of the sweeper 21.

[0024] Furthermore, the chutes 22 are symmetrically arranged at both ends of the sweeper 21. The other end of the spring 24 is fixedly connected with the outer wall of the fixing frame 2, which is beneficial to improving the sliding stability of the sweeper 21 by arranging the chutes 22 symmetrically at both ends of the sweeper 21, and achieving the effect of improving the cleaning efficiency of the sweeper 21 for impurities on the belt surface.

[0025] Embodiment 2: As Figure 1 、 Figure 2 and Figure 4As shown in the figure, a belt conveyor with a self-cleaning function proposed by the present utility model, compared with the first embodiment, as another implementation manner of the present utility model, a connecting plate 37 is fixedly connected to the outer wall of the frame 1 on one side of the chute 17. A scraper 3 is fixedly connected to the outer wall of the connecting plate 37 on one side of the cleaner 21. A discharge groove 31 is formed on the surface of the scraper 3. A threaded rod 32 is rotatably connected to the outer wall of the fixed frame 2. One end of the threaded rod 32 is fixedly connected to a servo motor 33. A threaded slider 34 that is slidably connected to the outer wall of the fixed frame 2 is threadedly connected to the outer wall of the threaded rod 32. A fixing groove 35 is formed at the connecting portion between the outer wall of the fixed frame 2 and the threaded slider 34. A cleaning rod 36 is fixedly connected to the outer wall of the threaded slider 34 on one side of the scraper 3. During operation, by providing the spring 24 and the cleaning rod 36, it is beneficial to improve the tight fitting effect between the cleaner 21 and the surface during the daily use of the belt conveyor, prevent the belt from vibrating and causing the cleaner 21 to fall off the belt, resulting in a decrease in the cleaning effect of the cleaner 21 on the surface of the belt when the belt is rotating. At the same time, through the scraper 3 that fits the surface of the belt, the impurities on the surface of the belt are effectively cleaned. At the same time, under the opening of the discharge groove 31, the impurities automatically fall, facilitating the automatic discharging operation of the impurities. And after the scraper 3 is used for a long time, the servo motor 33 can be periodically turned on. Through the rotation of the threaded rod 32, the threaded slider 34 is driven to slide along the inner wall of the fixing groove 35. The sliding of the threaded slider 34 drives the cleaning rod 36 to reciprocate along the inner wall of the discharge groove 31, achieving the effect of automatically cleaning the impurities adsorbed on the surface of the scraper 3 and improving the cleanliness of the surface of the scraper 3 during use.

[0026] Further, the outer wall contour of the scraper 3 is arc-shaped, and the discharge groove 31 is formed in a comb shape on the surface of the scraper 3. The chute 17 is arranged on the movement tracks of the cleaner 21 and the cleaning rod 36, which is beneficial to the effective discharging of the impurities on the surface of the belt by the scraper 3 due to the chute-shaped outer wall contour of the scraper 3.

[0027] Further, the threaded slider 34 forms a sliding structure with the fixing groove 35 through the threaded rod 32, which is beneficial to the rotation of the threaded rod 32 to drive the threaded slider 34 to slide along the inner wall of the fixing groove 35, realizing the control operation of driving the cleaning rod 36 to reciprocate.

[0028] Further, the scraper 3 is arranged on the movement track of the cleaning rod 36, and the outer wall contour of the cleaning rod 36 is comb-shaped, which is beneficial to automatically cleaning the impurities adsorbed on the surface of the scraper 3 by arranging the scraper 3 on the movement track of the cleaning rod 36, achieving the effect of improving the cleanliness of the surface of the scraper 3 during use.

[0029] Working principle: When using a belt conveyor with a self-cleaning function, during the daily use of the belt conveyor, in order to improve the close-fitting effect between the cleaner 21 and the surface, prevent the belt from vibrating, causing the cleaner 21 to fall off the belt, resulting in a decrease in the cleaning effect of the cleaner 21 on the surface of the belt when the belt is rotating, and with the opening of the chute 17, the cleaner 21 is discharged from the chute 17 and falls onto the impurity conveying belt for conveying. At the same time, through the scraper 3 that fits the surface of the belt, the impurities on the surface of the belt are effectively cleaned. At the same time, with the opening of the discharge chute 31, the impurities automatically fall, facilitating the automatic discharging operation of the impurities. And after the scraper 3 is used for a long time, the servo motor 33 can be regularly opened. Through the rotation of the threaded rod 32, the threaded slider 34 is driven to slide along the inner wall of the fixed groove 35. The sliding of the threaded slider 34 drives the cleaning rod 36 to reciprocate along the inner wall of the discharge chute 31, playing a role in automatically cleaning the impurities adsorbed on the surface of the scraper 3. At the same time, the inclined surface of the chute 17 is arranged on one side of the scraper 3, so that after the scraper 3 cleans the surface of the belt, the impurities will also fall into the inside of the chute 17 and be conveyed to the belt of the next layer, achieving the effect of automatically cleaning and automatically conveying the impurities, and improving the self-cleaning effect of the impurities on the surface of the belt.

[0030] This is the working principle of the belt conveyor with a self-cleaning function.
