Description

Technical Field

[0001] The present invention belongs to the technical field of dust collection, and particularly relates to an on-vehicle dust collection device for open-pit mines. Background Art

[0002] In open-pit mines, large transport vehicles are required to transport ores and rock waste. A large amount of dust is generated during the processes of loading and transportation, causing great pollution to the surrounding air environment. To reduce dust pollution, the traditional method is to sprinkle water to settle and absorb the dust in the air. Since sprinkling water is a waste of water resources and can make the roads muddy, there are also safety hazards when vehicles drive on icy roads in winter. Therefore, an air dust collector is currently usually used to replace sprinkling water to settle and absorb dust, so as to reduce the dust pollution to the air. Due to the large amount of dust in the mine, after the dust collector filters the dust, a large amount of dust accumulates in the dust collector, and the dust collected in the dust collector needs to be frequently cleaned, which is inconvenient to use. Summary of the Invention

[0003] The purpose of the present invention is to solve the above-mentioned technical problems existing in the prior art, and provide an on-vehicle dust collection device for open-pit mines, which can pat and compact the dust, reduce the cleaning frequency of the dust collector, and is applicable to an environment with a large amount of dust.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions:

The dust collection inlet is movably connected with a first opening and closing plate for controlling the opening and closing of the dust collection inlet. The dust collection outlet is provided with a second opening and closing plate for controlling the opening and closing of the dust collection outlet. The dust collection box is movably connected with a push plate to push the dust in the dust collection box to the dust collection outlet. A flapping plate is slidably connected in the dust collection box. The flapping plate is arranged above the second opening and closing plate. One end of the flapping plate is provided with a connecting rod, and the connecting rod is provided with a roller. The placement box is provided with a first motor, and the first motor is connected with a cam and drives the cam to rotate. The roller is connected with the cam. The top of the dust collection box is provided with an atomizing nozzle. A water tank is arranged on the side of the placement box. The water tank is provided with a water pump. The water inlet end of the water pump is communicated with the water tank, and the water outlet end of the water pump is connected with the atomizing nozzle. Through the water mist of the atomizing nozzle, the adhesiveness between the dust can be improved, which is convenient for the dust to be slapped into blocks. Through the cooperation of the dust collection chamber and the fan, the external dust can be inhaled. Then, the dust collection box is used to collect and compact the dust, reducing the volume occupied by the dust, reducing the cleaning frequency of the dust collector. And after the dust is compacted into blocks, it is convenient for the transportation of the dust and the subsequent reuse of the waste. Through the setting of the cam, the first motor can drive the flapping plate to move upward. Then, under the action of its own weight, the flapping plate makes the roller stick to the edge of the cam to realize the downward pressing and slapping. A counterweight can be set on the connecting rod to improve the effect of the downward pressing and slapping. A controller is set on the placement box to control the timing start of the water pump. The water pump pumps out the water in the water tank and sprays it after atomization through the atomizing nozzle to wet the dust accumulated in the dust collection box. By spraying a small amount of water mist regularly to wet the dust, the adhesiveness between the dust particles can be increased. And through the method of multiple times and small amounts, the possibility of over-wetting the dust can be reduced. A placement groove can be set on the top of the dust collection box and the atomizing nozzle can be arranged in the placement groove, reducing the influence on the movement of the push plate.

[0006] Further, the first opening and closing plate is slidably connected with the placement box. The placement box is provided with a first electric push rod, and the first electric push rod is connected with the first opening and closing plate and drives the first opening and closing plate to slide.
