[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1 and Figure 2 The utility model discloses a reaction force type belt cleaning device, which is used to clean the residual materials and residues stuck on the surface of the belt of the belt conveyor. The belt can be used to transport mineral materials, etc. Specifically, the belt cleaning device includes: a scraper shaft 5, a cleaning scraper 3, a roller brush 8 and two bearing seats 6; the two bearing seats 6 are fixed to the bracket 10 of the steering roller 2 by adjusting bolts 11, and the two ends of the scraper shaft 5 are rotatably installed in the two bearing seats 6 so that the scraper shaft 5 can rotate freely; the cleaning scraper 3 is installed by the scraper bracket 104 It is installed on one side of the scraper shaft 5 (that is, the scraper bracket 4 is fixed to one side of the scraper shaft 5, and the cleaning scraper 3 is connected to the end of the scraper bracket 4), and the other side of the scraper shaft 5 is fixedly installed with a roller brush 8 through a roller brush connecting rod 7 (that is, the roller brush connecting rod 7 is fixed to the other side of the scraper shaft 5, and the roller brush 8 is connected to the end of the roller brush connecting rod 7), and the cleaning scraper 3 and the roller brush 8 are both in contact with the outer surface of the belt 1; the cleaning device utilizes the reaction force when the cleaning scraper 3 or the roller brush 8 cleans the belt 1 to realize the cleaning function of the cleaning scraper 3 and the roller brush 8.

[0024] In an embodiment of the present invention, the bearing seat 6 is fixed to the bracket 10 of the steering roller 2 using an adjusting bolt 11, so that the installation height of the bearing seat 6 can be controlled by the adjusting bolt 11, and the distance between the scraper shaft 5 and the steering roller 2 can be adjusted, so that the cleaning scraper 3 and the roller brush 8 can be in close contact with the bottom belt 1. The bracket 10 of the steering roller 2 is provided with a jackscrew nut on the back and front sides adjacent to the two bearing seats 6, and a jackscrew 9 is passed through the jackscrew nut. The jackscrew nut is fixedly mounted on a jackscrew plate, and the jackscrew plate is fixedly mounted on the bracket 10 of the steering roller 2. The jackscrew 9 is used to adjust the horizontal installation position of the bearing seat 6.

[0025] In an embodiment of the present invention, the roller brush connecting rod 7 and the scraper bracket 4 are both made of titanium alloy, the roller brush 8 is made of rubber, and the cleaning scraper 3 can be made of rubber or the same material as the belt 1, and can also be selected according to the material being transported.

[0026] In an embodiment of the present invention, the roller brush 8 is arranged at the lowest point of the cleaning scraper 3 near the steering roller 2; the angle between the scraper bracket 4 and the roller brush connecting rod 7 is 45°~60°, and the specific angle can be set according to process requirements.

[0027] During use, when the conveyor belt 1 is running, after the roller brush 8 contacts the conveyor belt 1, the roller brush 8 rotates in the opposite direction under the action of the friction force of the belt 1 to achieve the cleaning function. When the roller brush 8 is cleaning, it will generate a downward reverse force, which will drive the scraper shaft 5 and the cleaning scraper 3, so that the belt 1 and the cleaning scraper 3 are in close contact, achieving the cleaning function. When the belt 1 and the cleaning scraper 3 are in close contact for cleaning, a horizontal outward reaction force will be generated. This force will drive the scraper shaft 5, the roller brush connecting rod 7 and the roller brush 8, so that the roller brush 8 is in close contact with the bottom of the belt 1, achieving the cleaning function. This reciprocating process will achieve the cleaning function of the belt 1.
