Abstract

The utility model discloses a dust-proof front canopy, which comprises a front canopy body, wherein two ends of the front canopy body are hermetically connected with baffles; one baffle is provided with a through hole; the pipe wall of the front canopy body is provided with a round hole; a spraying pipe is fixedly connected to the front canopy body; the spraying pipe is hermetically communicated with a spraying water curtain nozzle; the spraying water curtain nozzle corresponds to the round hole; one end of the spraying pipe is sealed; the other end of the spraying water curtain nozzle is hermetically communicated with a high-pressure pipe joint; and the high-pressure pipe joint penetrates through the through hole to the outer side of the baffle. In the dust-proof front canopy, the functions of a remote spraying device and the front canopy are combined into a whole. When the dust-proof front canopy is used, pressure water conveyed via an underground high-pressure water pipe serves as a water source and is conveyed to a sealed head via a high-pressure rubber pipe. A purpose of dust fall can be achieved by generating the water curtain by the water curtain nozzle, temporary timbering safety of the head is guaranteed, fully-sealing dust fall is realized, and the use effect is good.

Description

Dustproof forestope
Technical field
The utility model relates to a kind of mining device, relates in particular to a kind of dustproof forestope.
Background technology
At present, adopt in the tunnel of drilling and blasting method construction at coal road and half coal rock tunnel, blow out with hoeing be topmost product dirt operation; The dust-producing amount of meeting head on accounts for 80% of each operation dust-producing amount, and the measure of control dust generally is to adopt spraying curtain or spray bar, but owing to blowing out influence; Spraying curtain and spray bar be fixing difficulty before raking loader; And the water curtain that forms is difficult to cover whole meeting head on, and dust-laying effect is bad, and amounts of dust brings serious threat for miner's life.
Summary of the invention
The purpose of the utility model provides the good dustproof forestope of a kind of dust-laying effect.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:
A kind of dustproof forestope comprises the forestope main body, it is characterized in that: the airtight baffle plate that is connected with in the two ends of forestope main body, wherein have through hole on a baffle plate, and have circular hole on the tube wall of forestope main body; Be fixedly connected with injection spray pipe in the forestope main body; The airtight atomizing drencher head that is communicated with on the injection spray pipe; The atomizing drencher head is corresponding with circular hole, the end sealing of injection spray pipe, the airtight high-pressure pipe connector that is communicated with of the other end, and high-pressure pipe connector passes to the baffle plate outside from through hole.
The utility model unites two into one the function of remote spray device and forestope; The press water that adopts the conveying of down-hole high pressure water pipe during use is as the water source; Be sent to sealing through high-pressure rubber pipe and meet head on, rely on the atomizing drencher head to produce the purpose that water curtain reaches depositing dust, the safety of the temporary lining that both guaranteed to meet head on; Realized totally-enclosed depositing dust again, result of use is good.
Description of drawings
Fig. 1 is the structural representation of the utility model.
In the accompanying drawing:
1, through hole; 2, high-pressure pipe connector; 3, baffle plate; 4, forestope main body; 5, injection spray pipe; 6, atomizing drencher head; 7, circular hole.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:
A kind of dustproof forestope, as shown in Figure 1, comprise forestope main body 4, the airtight baffle plate 3 that is connected with in the two ends of forestope main body 4 wherein has through hole 1 on a baffle plate 3, has circular hole 7 on the tube wall of forestope main body 4; Be fixedly connected with injection spray pipe 5 in the forestope main body 4; The airtight atomizing drencher head 6 that is communicated with on the injection spray pipe 5; Atomizing drencher head 6 is corresponding with circular hole 7, the end sealing of injection spray pipe 5, the airtight high-pressure pipe connector 2 that is communicated with of the other end, and high-pressure pipe connector 2 passes to baffle plate 3 outsides from through hole 1.
Using the utility model can reduce big gun pick meet head on the to blow out dust that produced with the hoeing two procedures and don't influence blows out and normally the carrying out of hoeing operation.
The utility model mainly utilizes the temporary lining of boring head---and the forestope and the injection spray pipe of 3 cun steel pipe manufacturings make up; Interval by 1.0 meters on the tube wall of forestope main body gets out 3 Φ 25mm circular holes; Make 3 shower nozzles on the injection spray pipe corresponding with the circular hole on the forestope main body; And seal the two ends of forestope main body with plate washer, the plate washer place of end sealing therein is installed with through hole, and Φ 10mm high-pressure pipe connector passes from through hole.
That this device has is simple in structure, easy to make, in light weight, the sealing feeding, reduce airborne dust, reduce advantages such as labor strength.
Use the utility model can reduce the dust that the big gun pick meets head on to blow out and the hoeing two procedures is produced, through on-site measurement, full dirt and respirable dust reduce by 71% and 50% respectively, and following table is to use the dust parameter index before and after the utility model:
Project Unit Before the use After the use
Full dirt ㎎/m3 30 ~35 9.0 ~9.8
Respirable dust ㎎/m3 4.2 ~7.8 2.5 ~3.5
