[0023] The technical solution of one embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example

[0025] like Figure 1-3 As shown, one embodiment of the present invention provides a belt conveyor coal cleaning machine, including two side plates 1. A reversible dual pneumatic motor 2 is fixedly installed on the inner side of each side plate 1. Mounting grooves 101 are provided on the outer side of each side plate 1. The two output ends of the reversible dual pneumatic motor 2 extend into the two mounting grooves 101, and each output end of the reversible dual pneumatic motor 2 is provided with a first chain 3. A first connecting shaft 4 is installed between the ends of the two first chains 3 located on the side of the mounting groove 101 away from the reversible dual pneumatic motor 2. The first connecting shaft 4 is rotatably connected between the two side plates 1. A second connecting shaft 5 is provided on one side. The first connecting shaft 4 and the second connecting shaft 5 are connected by a cleaning chain tensioning mechanism. At least two fixedly connected first sprockets 6 are sleeved on the first connecting shaft 4. At least two second sprockets 7 adapted to the first sprockets 6 are sleeved on the second connecting shaft 5. A compatible second chain 8 is sleeved between each pair of first sprockets 6 and second sprockets 7. At least one feeder 9 is installed on the surface of each second chain 8. The second chain 8 is changed from a linear motion type to an oblique motion type. The linear motion type has gaps in the middle and cannot completely clean out the coal slag. The oblique motion type can clean more thoroughly by alternating movement.

[0026] The top surfaces of the two side plates 1 located near the second chain 8 are each equipped with a first connecting seat 11 that is fixedly connected. A first connecting rod 12 is fixedly installed between the two first connecting seats 11. A coal scraper 13 is provided on the first connecting rod 12.

[0027] Two straight rods 17 are fixedly connected to the ends of the two side plates 1 located away from the second chain 8. A crossbar 18 is fixedly connected between the tops of the two straight rods 17. Handle switches 19 that are electrically connected to the forward and reverse dual pneumatic motors 2 are provided at both ends of the crossbar 18.

[0028] The bottom of the floating coal cleaning machine is made of a material similar to soft rubber to scrape out the coal slag without causing it to get stuck.

[0029] To ensure the stability of the device's movement, as a further embodiment of the present invention, the cleaning chain tensioning mechanism includes a first sleeve 24 and a second sleeve 25 respectively sleeved on the first connecting shaft 4 and the second connecting shaft 5. The first sleeve 24 is rotatably connected to the first connecting shaft 4, and the second sleeve 25 is rotatably connected to the second connecting shaft 5. An elastic telescopic tensioning bracket 26 is fixedly connected between the first sleeve 24 and the second sleeve 25.

[0030] To facilitate the fixation of the entire device, as a further embodiment of the present invention, a second connecting seat 14 is fixedly installed on the inner side of each of the two side plates 1. A second connecting rod 16 is fixedly connected to the surface of each of the two second connecting seats 14. A connecting plate 27 is fixedly installed between the two second connecting rods 16. An elastic retractor 28 is provided on the surface of the connecting plate 27. A pressure plate 30 is installed at the pressure end of the elastic retractor 28, and a fixed cone 29 is fixedly connected to the output end of the elastic retractor 28. The fixed cone 29 passes through the connecting plate 27 and is slidably connected to the connecting plate 27. The internal structure of the elastic retractor 28 is similar to the telescopic structure inside a ballpoint pen, which is common knowledge to those skilled in the art and will not be described in detail here.

[0031] In order to increase the friction of the pressure plate 30 surface and prevent slippage when stepping on the pressure plate 30, as a further embodiment of the present invention, the pressure plate 30 surface is provided with anti-slip grooves.

[0032] To facilitate the movement of the entire device, as a further embodiment of the present invention, each of the two second connecting seats 14 is equipped with a first universal wheel 15.

[0033] To prevent the second universal wheel 23 from affecting the work, as a further embodiment of the present invention, a drive motor 20 is installed on the side of the straight rod 17, and a rotating shaft 21 is installed at the output end of the drive motor 20. The two ends of the rotating shaft 21 are respectively rotatably connected to the inner sides of the two side plates 1. A connecting post 22 is fixedly connected on the rotating shaft 21, and the second universal wheel 23 is installed at the end of the connecting post 22.

[0034] To prevent the second chain 8 from being exposed and reducing the product's service life, as a further embodiment of the present invention, a top cover 10 is fixedly connected to the ends of the two side plates 1 located above the second chain 8.

[0035] Please see Figure 4 To facilitate the use of the fixed cone, another embodiment of the present invention provides a belt conveyor coal cleaning machine. This embodiment differs from the previous embodiment in the installation position of the fixed cone 29. The second connecting rod 16 is fixedly installed on the inner side of the ends of the two side plates 1 near the straight rod 17. A connecting plate 27 is fixedly installed between the two second connecting rods 16. An elastic retractor 28 is provided on the surface of the connecting plate 27. A pressure plate 30 is installed at the pressure end of the elastic retractor 28, and a fixed cone 29 is fixedly connected to the output end of the elastic retractor 28. The fixed cone 29 passes through the connecting plate 27 and is slidably connected to it. The internal structure of the elastic retractor 28 is similar to the telescopic structure inside a ballpoint pen, which is common knowledge to those skilled in the art and will not be described in detail here.

[0036] Working principle: When in use, place the device on one side of the conveyor belt walkway, turn on the forward and reverse dual pneumatic motor 2, adjust the position of the cleaning machine, drive the first chain 3 and the second chain 8 to rotate through the handle switch 19, and move the cleaning machine forward with the first universal wheel 15 and the second universal wheel 23. Manually control the forward movement speed. The cleaning machine cleans the floating coal on one side of the conveyor belt. Continue to move forward to the other side of the conveyor belt. Manually control the forward movement speed. The cleaning machine cleans the floating coal on the other side of the conveyor belt to the middle of the conveyor belt. Then rotate the operating handle. The cleaning machine moves backward and at the same time the scraper plate 13 pushes the floating coal cleaned on the other side out of the conveyor belt.

[0037] The handle switch 19 has a function similar to that of a motorcycle, which will not be described in detail here. Turning it back will turn on the forward and reverse dual pneumatic motor 2, and the cleaner will move forward to under the belt. Turning the handle back will stop the movement. Stepping on the fixed cone 29 and continuing to turn the handle will cause the forward and reverse dual pneumatic motor 2 to continue to rotate, driving the feeder 9 on the second chain 8 to rotate. Since the fixed cone 29 fixes the machine, the feeder 9 can only rotate in place, thus scraping out the loose coal. After cleaning, turning the handle forward will cause the feeder 9 on the second sprocket 7 to reverse and push out the loose coal.
