Sweeping brush dust falling device and sweeping equipment

Abstract

The invention discloses a sweeping brush dust falling device and sweeping equipment. The sweeping brush dust falling device comprises a sweeping brush, a foam liquid system and a foam blowing system,the foam liquid system comprises a foam liquid storage box, a foam liquid conveying pipe and annular overflow pipes, and foam liquid stored in the foam liquid storage box is conveyed to the annular overflow pipes adjacent to the sweeping brush through the foam liquid conveying pipe below the foam liquid storage box and then sprayed out through a foam liquid nozzle on the inner ring of the annularoverflow pipe; the foam blowing system comprises a gas supply device, a gas conveying device and gas flow nozzles arranged in one-to-one correspondence with the annular overflow pipes, the gas conveying device conveys gas provided by the gas supply device to the gas flow nozzles, and the gas flow nozzles are opposite to the inner rings of the annular overflow pipes. According to the scheme, raiseddust caused by sweeping operation is effectively reduced in a foam dust falling mode, and compared with a spraying dust falling mode, the scheme can greatly reduce the water consumption and greatly improve the dust suppression efficiency; and the size of the water tank is greatly reduced, a water pump and a high-pressure water path are omitted, the structure is simplified, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of sanitation vehicles, in particular to a sweeping and dust-reducing device and a cleaning device. Background technique [0002] The existing road cleaning equipment with sweeping brushes generally adopts the spray dust reduction method, that is, 2 to 3 high-pressure atomizing nozzles are arranged on the side where the sweeping brush touches the ground. Large-tonnage cleaning vehicles are equipped with a large nozzle flow rate, which can wet the unswept area in front of the brush. The wet dust is stirred by the brush and turns into mud. After the operation, it is painted on the ground to show mud marks; For areas where there is not much dust on the ground, a lot of water remains on the ground after the operation in the area covered by the atomizing nozzle. Small-tonnage road cleaning equipment cannot carry large water tanks, so it can only use small-flow high-pressure atomizing nozzles for spraying and dus...

AI Technical Summary

Problems solved by technology

[0004] 1) The existing spray dust suppression method is difficult to achieve a good dust suppression effect;

[0005] 2) The water consumption is large, and a large water tank needs to be equipped. On the basis of the limited vehicle volume, the layout space of the garbage can and other accessories must be compressed. After the volume of the garbage box is compressed, the effective volume for containing the garbage is reduced. Conducive to the continuous operation of the road sweeper;

[0006] 3) The road sweeper needs to be filled with a tank of water when going out to work. For a pure electric road sweeper, the increase in load will lead to an increase in power consumption, which will reduce the working mileage of the road sweeper
