Abstract

The present invention discloses an automatic sprayer of blasting, which is composed of a spray gun body and a nozzle. The tail of the spray gun body is provided with a high-pressure wind inlet pipe and a high-pressure water inlet pipe. The nozzle is a wedge-shaped nozzle. The upper surface, the lower surface, the front surface and the back surface of the wedge-shaped nozzle are provided with spraying holes. A high-pressure blower which supplies wind to the high-pressure wind inlet pipe is provided with a blasting vibration automatic opening device. The nozzle is installed in the middle part of the laneway top which is separated from the working surface for 25-30 meters. The automatic sprayer of blasting of the invention has the advantages of: safe and convenient using, good construction environment, capability for removing dust instantly, and water resource saving.

Description

technical field [0001] The invention relates to a dedusting device, in particular to an automatic blasting spray device for instant automatic spraying and dust reduction during the excavation and blasting process of the second and third phases of mine construction flat (inclined roadway) projects. Background technique [0002] At present, during the construction of the second and third phases of the coal mine, it is necessary to spray water and dust according to the regulations during each blasting of the roadway excavation. Due to the low water pressure, it takes a long time to start the spray after each blasting, and the dust removal effect is poor. According to the three- and eight-work system, three cycles of footage are used to calculate: one cycle of footage is fired twice, and the dust after one shot is at least (10-15 minutes) sprinkled and dusted, and the water is about (40-50 kg), one working day. Sprinkling water to reduce dust just needs (60-90 minutes) spraying ...
