To achieve the above object, the present invention uses following technical proposals：
A kind of high pneumatic dth drill orients dust discharge depositing dust cover, including depositing dust cover, screen pack and dust discharge position plate, the drop
Dust hood includes full symmetric left and right two parts, and the top of the depositing dust cover is provided with airtight part, the bottom one of the depositing dust cover
It is provided with grid hollow-out parts week, screen pack, the removable dust discharge of grid hollow-out parts outer surface covering is provided with inside the depositing dust cover
Position plate.
The depositing dust cover is hemispherical shape.
Left and right two parts side of the depositing dust cover is provided with rotating shaft, and left and right two parts are linked together by rotating shaft, rotated
Axle can be rotated, and the two-part opposite side in left and right of the depositing dust cover is provided with snib.
The top end opening of the depositing dust cover, open interior is provided with sealing sponge with clamping drilling rod.
The screen pack is attached to depositing dust cover inwall, and rig is fitted on depositing dust cover inwall when working with gas pressure.
Two pieces of dust discharge position plates are covered each by left and right two parts of the depositing dust cover, air-flow is prevented, dust is never hidden
Discharged at gear.
The dust discharge position plate blocks a part of grid hollow-out parts, dust is discharged from remaining grid hollow out position.It is described
/ 2nd of the total lateral area of dust discharge position plate less than grid hollow-out parts lateral area.
The depositing dust cover and dust discharge position plate are corrosion resistant metal material.The dust discharge position plate is fixed on outside depositing dust cover
Draw-in groove on, slidably position, dust discharge direction is changed with this.
The screen pack is recyclable fibers material, and different mesh-densities are can be directed to design for different depositing dust requirements
Screen pack.
When using, depositing dust cover is opened from snib one end, will be stuck on drilling rod at upper opening, closes depositing dust cover, shuts card
Bolt, regulation dust discharge position plate direction, then starts drilling, and now device starts depositing dust dust discharge.
Beneficial effects of the present invention are：The present invention realizes effective control of the dust that drilled to blast high, to the anti-dry of wind
Immunity is strong, reduces the diffusion of dust, it is to avoid staff sucks excessive dust, improves construction working environment.Device is whole
Body is simple to operation, and material environment friendly low cost is easy-maintaining, it is adaptable to various drillings and construction environment, is particularly suited for windy field
Rig operation.

Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples.
As Figure 1-Figure 5, high pneumatic dth drill orientation dust discharge depositing dust cover, including depositing dust cover, screen pack 7, dust discharge are fixed
To plate 2.Big particle diameter dust is filtered by screen pack 7, and thin dirt and gas pass through pact of the grid hollow-out parts 3 in dust discharge position plate 2
Discharge is oriented under beam.Depositing dust cover and dust discharge position plate 2 are corrosion resistant metal, and depositing dust cover is symmetrically closed for two a quarter spheroid shells
Close, two a quarter spheroid shells one end rotating shaft 5 is connected, and the other end is connected using snib 6.Depositing dust cover bottom one week is hollow out
Lattice portion 3, grid is square, and top is airtight part 1.Screen pack 7 is set in depositing dust cover, with gas pressure when rig works
It is fitted on depositing dust cover inwall, screen pack 7 can be directed to design using cheap recyclable fibers material for different depositing dust requirements
The screen pack 7 of different mesh-densities.Dust discharge position plate 2 is covered in grid hollow-out parts, institute's cover height and the height of grid hollow-out parts 3
Unanimously, dust discharge position plate 2 is the airtight plate of solid metal, and edge is provided with draw-in groove 8 to fix dust discharge position plate 2 in grid hollow-out parts 3,
Dust discharge position plate 2 can be slided along draw-in groove 8, and dust discharge direction is changed with this.Dust discharge position plate 2 is provided with four pieces, each four/
Two pieces on one spheroid shell, air-flow is prevented, discharge the dust never place of blocking.The top end opening of depositing dust cover, open interior is provided with close
Envelope sponge 4 is with clamping drilling rod.
Depositing dust cover is opened from the one end of snib 6, and screen pack 7 is attached into depositing dust cover inwall (airtight part 1 and grid hollow-out parts
3), depositing dust cover upper opening is snapped on high pneumatic dth drill drilling rod, depositing dust cover is closed, snib 6, regulation dust discharge orientation is locked
The direction of plate 2, makes the exposed portion of depositing dust cover grid hollow-out parts 3 against being conducive to depositing dust and do not interfere with the direction of skilled worker,
Depositing dust cover bottom and ground are brought into close contact, rig are then started and is started drilling, at this moment high pneumatic dth drill orientation dust discharge drop
Dust hood just starts to play depositing dust and orientation dust discharging function：The native rock ballast and floating dust that are produced when drilling are carried out into filtering precipitation, it is impossible to
The orientation discharge of precipitation, concentrates hole slag and is deposited in depositing dust cover, reduce the diffusion of dust, it is to avoid staff's suction is excessive
Dust.
Although above-mentioned be described with reference to accompanying drawing to specific embodiment of the invention, not to present invention protection model
The limitation enclosed, one of ordinary skill in the art should be understood that on the basis of technical scheme those skilled in the art are not
Need the various modifications made by paying creative work or deformation still within protection scope of the present invention.
