Description

Dust suppression device of coal conveyor Technical Field The utility model belongs to the technical field of coal conveying machines, and relates to a dust suppression device of a coal conveying machine. Background The power plant is a factory for producing electric energy, the produced electric energy can utilize wind energy, water potential energy and chemical power generation, but main electric power production in China is thermal power generation by burning coal. In the transportation process of coal materials, a coal conveyer is generally used for transporting the coal conveyer, but in the transportation process of the coal conveyer, coal dust such as coal dust and small coal blocks can be remained on the working surface of a conveyor belt of the coal conveyer, if the coal dust is not removed at the discharging end of the coal conveyer, the coal dust can fly upwards along with the reciprocating transportation of the coal conveyer, and the coal dust in a coal conveyer area is caused, so that the problem is solved by the coal conveyer dust suppression device for carrying out dust suppression operation on the residual coal dust on the surface of the conveyor belt by the coal conveyer dust suppression device. Disclosure of utility model Aiming at the problems, the utility model provides a dust suppression device of a coal conveyor, which well solves the problems in the prior art. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: The utility model provides a coal conveyor presses down dirt device, includes the conveyer belt that is used for carrying coal that is driven by the coal conveyor, the downside of conveyer belt is equipped with the collecting box that gathers the buggy, the downside butt of conveyer belt has two rollers, and the downside of every roller all is equipped with the scraper blade that is used for striking off the buggy in the roller outside, the inside of collecting box is equipped with mobilizable regulating plate, every the bottom of scraper blade all with the regulating plate rotates to be connected, the inside of collecting box is equipped with the spraying mechanism that is used for pressing down the dirt. Preferably, each of the left and right sides of the scraping plate is fixedly connected with a connecting block, the middle of each connecting block is provided with a connecting hole, each of the left and right sides of the roller is fixedly connected with a rotating block, and each rotating block is rotationally connected with the corresponding connecting hole through a bearing. Preferably, the bottom of each scraper blade is fixedly connected with a power block, and the downside of each power block is rotationally connected with the adjusting plate.
