[0025] Figure 1 is a schematic diagram showing the structure of a belt conveyor cleaning device according to an exemplary embodiment;

[0026] Figure 2 According to an exemplary embodiment, Figure 1 The middle is an enlarged view of part A showing the location of the deformation groove. Figure 1 and Figure 2 Provide explanation.

[0027] Some specific implementation modes described below are intended to facilitate those skilled in the art to understand the present embodiment, and the present embodiment is not limited to some specific implementation modes described below.

[0028] Reference Figure 1 and Figure 2 An exemplary embodiment of the present disclosure provides a belt conveyor cleaning device, the belt conveyor cleaning device comprising:

[0029] The base 1 is fixed on the belt conveyor and has a water inlet 11 and a water outlet 14.

[0030] The scraper 2 is used to be fixed to the base 1 and to abut against the belt. The scraper 2 includes a base plate 21 fixed to the base 1 and a knife plate 23 detachably connected to the base plate 21. There are multiple knife plates 23 and they are sequentially abutted and arranged along the length direction of the base 1.

[0031] The water spraying part 3 is movably connected to the base 1 , and has a first posture of spraying toward the belt and a second posture of spraying toward the scraper 2 .

[0032] For example, refer to Figure 1 and Figure 2The base 1 includes a pipe with one end closed and the other end open. The open end of the base 1 is a water inlet 11. There are multiple water outlets 14 distributed at intervals on the outer wall of the base 1 along the length direction of the base 1. There are multiple water spray parts 3 and they are respectively fixed at the positions where the water outlets 14 are opened on the outer wall of the base 1. Each water spray part 3 corresponds to a water outlet 14. The water spray part 3 is connected to the water outlet 14, and the water in the base 1 enters the water spray part 3 through the water outlet 14. The water spray part 3 includes a metal bellows 31 fixed to the base 1 and a nozzle 32 threadedly connected to the metal bellows 31. One end of the metal bellows 31 is fixedly connected to the outer wall of the base 1 and communicates with the inside of the base 1. The other end of the metal bellows 31 is fixedly connected to the nozzle 32. By bending the metal bellows 31, the direction of the nozzle 32 fixed to the end of the metal bellows 31 can be changed, that is, the nozzle 32 changes between the first posture and the second posture, which is used to change the spray direction of the water flow.

[0033] The base plate 21 is in the shape of a long straight plate arranged along the length direction of the base 1. One side of the base plate 21 is fixedly connected to the side wall of the base 1, and the other side of the base plate 21 extends in a direction away from the base 1. The blade plate 23 also includes a connecting plate 22 for detachably connecting the base plate 21. The connecting plate 22 is detachably connected to the blade plate 23. There are multiple connecting plates 22 and they are spaced apart along the length direction of the base plate 21. The side walls of two adjacent connecting plates 22 abut against each other. One side of the connecting plate 22 is bolted to the base plate 21, and the other side of the connecting plate 22 is bolted to the blade plate 23. The connecting plate 22 and the base plate 21 are fixed by at least two bolts spaced apart along the length direction of the base plate 21. Similarly, the connecting plate 22 and the blade plate 23 are fixed by at least two bolts spaced apart along the length direction of the base plate 21. Each connecting plate 22 is only connected to one blade plate 23. The blade plate 23 is flush with the base plate 21. The connecting plate 22 covers part of the outer wall of the base plate 21, and the connecting plate 22 covers part of the outer wall of the blade plate 23. A drainage port 26 is provided on the blade 23 and passes through the scraper 2 along the belt conveying direction, that is, the axial direction of the drainage port 26 is perpendicular to the length direction of the base 1, and the axial direction of the drainage port 26 is perpendicular to the blade 23. Three drainage ports 26 are provided on each blade 23, and the three drainage ports 26 are spaced apart along the length direction of the base 1, and the drainage ports 26 are spaced apart from the side of the blade 23 away from the base plate 21.

[0034] In this embodiment, by connecting the base 1 to an external water source, water flows from the water outlet 14 through the water spraying part 3 to the scraper 2 or directly onto the belt to wet the belt, thereby reducing the risk of friction fire when too much coal accumulates on the belt.

[0035] In an exemplary embodiment of the present disclosure, referring to Figure 1 and Figure 2Part of the connecting plate 22 is located between the base plate 21 and the blade plate 23 , and a deformation groove 25 extending along the arrangement direction of the blade plates 23 is opened on the connecting plate 22 , and the deformation groove 25 is located between the base plate 21 and the blade plate 23 .

[0036] For example, refer to Figure 1 and Figure 2 The connecting plate 22 has a boss 24 extending toward the base plate 21 and the blade plate 23. The boss 24 extends between the blade plate 23 and the base plate 21. The side wall of the base plate 21 facing away from the base 1 abuts against the boss 24. The side wall of the blade plate 23 facing the base 1 abuts against the boss 24. The base plate 21 and the blade plate 23 are respectively located on opposite sides of the boss 24. The deformation groove 25 is provided on the side wall of the connecting plate 22 facing away from the base plate 21 and the blade plate 23, and the position of the deformation groove 25 corresponds to the position of the boss 24. The deformation groove 25 extends along the length direction of the base 1 and passes through the connecting plate 22. The setting of the deformation groove 25 can provide the knife plate 23 with a certain posture change possibility when the knife plate 23 scrapes hard and difficult-to-move impurities on the belt, that is, the deformation groove 25 reduces the difficulty of bending the connecting plate 22 and reduces the possibility of direct breakage of the connecting plate 22, so that the knife plate 23 can pass over the difficult-to-scrape impurities on the belt at the current position, reducing the possibility of damage to the knife plate 23 and the connecting plate 22.

[0037] In an exemplary embodiment of the present disclosure, referring to Figure 1 and Figure 2 The end of the base 1 has a threaded structure 12 for threaded connection to the belt conveyor.

[0038] For example, refer to Figure 1 and Figure 2 The threaded structure 12 is located at the end of the base 1. The base 1 can be fixed to the frame of the belt conveyor or other foundation through the threaded structure 12. A nut 13 for contacting the belt conveyor is threadedly connected to the threaded structure 12, and part of the threaded structure 12 is exposed from the outside of the nut 13. After the base 1 is fixed to the belt conveyor through the threaded structure 12 at the end of the base 1, the nut 13 is rotated to make the nut 13 contact the frame or other foundation of the belt conveyor. The base 1 maintains a stable posture by increasing the friction between the threaded structure 12 on the base 1 and the belt conveyor. Similarly, the scraper 2 can also have a more inclined posture by changing the deflection angle of the base 1 and tightening the nut 13.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
