Abstract
The invention discloses a front canopy automatic water curtain of a digging and blasting working surface and a working method thereof. The front canopy automatic water curtain comprises a shower nozzle, a water pipe and an automatic control device, wherein the shower nozzle is mounted in the inner groove of a front canopy, which is 1-2 meters far from the digging and blasting working surface; the automatic control device is mounted at the back end of the front canopy; the water pipe is communicated with the shower nozzle, then extends into the back end of the front canopy from the inner groove of the front canopy and is communicated with the water outlet of the automatic control device; the automatic control device is structurally composed of a water valve, an impacting plate, a supporting rod, a chuck, a heavy hammer and a connecting rod mechanism; the heavy hammer is connected to the rotatable chuck through the supporting rod and the heavy hammer at a normal state is located at a closed position of a handle of the water valve; the impacting plate is fixed at one end of the connecting rod mechanism and the plate surface of the impacting plate faces to a blasting and impacting direction; and the other end of the connecting rod mechanism is clamped into a clamping groove of the chuck at a normal state so that the clamping disc is at a locking state. The front canopy automatic water curtain has an automatic function of blasting impact waves and automatically spraying and has high flexibility; and the front canopy automatic water curtain can spray while blasting.
Description
Technical field
The present invention relates to mine underground dustproof equipment.
Background technology
Under coal mine, gun diging face is all provided with automatic sprayer at present, to eliminate the flue dust after blowing out.Existing atomization mechanism is, near tunnel work plane, shower nozzle is set, and electromagnetic valve or pendulum are controlled the unlatching of spraying automatically.Have the following disadvantages: when dustproof water quality is bad, electromagnetic valve is blocked easily burns with electromagnetic valve frequent starting; Fog-spray nozzle is installed from work plane and is easily blown out and break close to too, installation too far away, and work plane accumulates flue dust.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of gun diging face forestope automatic water curtain.Generally all adopt forestope to do interim roof timbering at gun diging face.The present invention is applicable to the gun diging face with forestope temporary lining.
For achieving the above object, the technical scheme that the present invention takes is: it comprises shower nozzle, water pipe and automaton, it is characterized in that, described shower nozzle is arranged in the inside groove of the forestope at gun diging face 1-2 rice; Described automaton is arranged on the rear end of forestope; Described water pipe and shower nozzle extend to forestope rear end after connecting from forestope inside groove, and connect with the delivery port of automaton; The structure of described automaton is: it comprises penstock, shock plate, support bar, chuck, weight and linkage; Weight is connected on rotating chuck by support bar, the fastening position of normality lower heavy punch in penstock handle; Shock plate is fixed on one end of linkage, and plate face is in face of blowing out impact direction; Under the other end normality of linkage, be stuck in the draw-in groove of chuck, chuck is in the lock state.
Operating principle of the present invention is: the gas shock wave during by face firing is in shock plate, drivening rod mechanism action, and linkage departs from the draw-in groove of chuck, falls to acting on penstock handle, and then open water valve and carry out atomizing de-dusting after weight release; After depositing dust process finishes, manually close penstock and stop spraying, in the time blowing out next time, restart.
Advantage of the present invention is:
1, there is Blasting shock wave auto spraying function, highly sensitive; Blow out and spray.
2, fog-spray nozzle is arranged in forestope groove, and the one, fog-spray nozzle is difficult for being bombarded damage, and the 2nd, near apart from work plane, while blowing out, whole big gun district is surrounded in spraying, increases dust-laying effect.
3, all accessories of automaton can be contained in an iron case, and compact conformation is easy to carry and installs.
The present invention is through trying out at applicant 71503E return airway, and trial effect is fine, now applies at all driving faces in full ore deposit.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
In figure: 1-shock plate, 2-linkage, 3-chuck, 4-draw-in groove, 5-weight, 6-handle, 7-penstock, 8-forestope, 9-water pipe, 10-shower nozzle.
The specific embodiment
As shown in Figure 1, the present invention includes shower nozzle 10, water pipe 9 and automaton, shower nozzle 10 is arranged in the inside groove of the forestope 8 at gun diging face 1-2 rice; Automaton is arranged on the rear end of front spy 8 beams; Water pipe 9 extends to forestope 8 rear ends after connecting with shower nozzle 10 from forestope 8 inside grooves, and connects with the delivery port of automaton; The structure of described automaton is: it comprises penstock 7, shock plate 1, support bar, chuck 3, weight 5 and linkage 2; Weight 5 is connected on rotating chuck 3 by support bar, the fastening position of normality lower heavy punch 5 in penstock 7 handles; Shock plate 1 is fixed on one end of linkage 2, and plate face is in face of blowing out impact direction; Under the other end normality of linkage 2, be stuck in the draw-in groove of chuck 3, chuck 3 is in the lock state.
Work of the present invention is: the gas shock wave during by face firing is in shock plate 1, and drivening rod mechanism 2 moves, and linkage 2 departs from the draw-in groove of chuck 3, falls to acting on penstock 7 handles, and then open water valve and carry out atomizing de-dusting after weight release; After depositing dust process finishes, manually close penstock 7 and stop spraying, in the time blowing out next time, restart.
Claims (1)
1. a method of utilizing forestope automatic water curtain gun diging face to be carried out to dedusting, it is characterized in that, described forestope automatic water curtain structure is: it comprises shower nozzle, water pipe and automaton, and described shower nozzle is arranged in the inside groove of the forestope at gun diging face 1-2 rice; Described automaton is arranged on the rear end of forestope; Described water pipe and shower nozzle extend to forestope rear end after connecting from forestope inside groove, and connect with the delivery port of automaton; The structure of described automaton is: it comprises penstock, shock plate, support bar, chuck, weight and linkage; Weight is connected on rotating chuck by support bar, the fastening position of normality lower heavy punch in penstock handle; Shock plate is fixed on one end of linkage, and plate face is in face of blowing out impact direction; Under the other end normality of linkage, be stuck in the draw-in groove of chuck, chuck is in the lock state;
