Abstract
The utility model discloses a spraying device of tunneling machines, which comprises a spraying device equipped with a plurality of nozzles. The spraying device is arranged on the cutting outer arm, which does not stretch or move with the cutting head. The cutting outer arm equipped with the spraying device do not stretch or move with the cutting head, thereby preventing the spraying device from getting in and out of coal bed frequently with the cutting head. The mist sprayed out is continuous and stable and has a good dust suppression effect. Nozzles are out of touch with the coal bed and thus are not easy to be blocked by coal dusts. The spraying device of the present utility model also has the advantages of low failure rate and high reliability.
Description
Technical field
The utility model relates to a kind of development machine that is applicable to mining, specifically is a kind of development machine atomization mechanism.
Background technology
When development machine was worked in the coal mining lane, cutterhead is one section degree of depth of rotary drilling at first, sweeps coal then up and down, in this process, can produce a large amount of coal dusts, and known development machine outwards sprays water smoke by the nozzle that is installed on the cutterhead, to eliminate coal dust.But the technical problem that exists is that along with cutterhead rotary drilling coal seam, nozzle has also and then entered the coal seam, the water smoke that sprays be along with the drilling depth of cutterhead can reduce gradually, and until not having, dust-laying effect is bad, and nozzle is stopped up by coal dust after frequently going deep into the coal seam easily.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides that a kind of atomizing de-dusting is effective, the not susceptible to plugging development machine atomization mechanism of nozzle.
The technical solution adopted in the utility model is: a kind of development machine atomization mechanism, comprise the humidifier that a plurality of nozzles are installed, and humidifier is installed in not on the cut outer arm with the cutterhead telescopic moving.
Humidifier is installed on the cut outer arm, along with the creeping into withdrawal and do not move of cutterhead, is not positioned at all the time outside the digging coal seam, can continue to cut face implementation atomizing de-dusting, atomizing de-dusting is effective, and nozzle do not follow the coal seam to contact, can blockage phenomenon.
Above-mentioned humidifier comprises the square frame that is installed on the cut outer arm, and a plurality of nozzles are set on the square frame, interconnects by the moulding internal cavities between the nozzle.In order to obtain best dust-laying effect, uniform a plurality of nozzles on the moulding of square frame both sides.
Above-mentioned humidifier comprises the ring frame that is installed on the cut outer arm, and uniform a plurality of nozzles on the ring frame interconnect by the moulding internal cavities between the nozzle.
The utility model is set to humidifier not on the cut outer arm with the cutterhead telescopic moving, make humidifier can frequently not pass in and out the coal seam with cutterhead, the water smoke that is sprayed continues and is stable, dust-laying effect is good, and nozzle does not contact the coal seam, be difficult for being stopped up by coal dust, fault rate is low, and functional reliability is good.
