Further, it is preferable to which the quantity of showerhead hole 11 is several, and several showerhead holes 11 are along the end face of the second end of tube wall
It is provided at circumferentially spaced, each showerhead hole 11 is correspondingly connected with an atomizer.
By above-mentioned improvement, several atomizers carry out 360 degree by spraying to the dust at nozzle 30 jointly, increase sprinkling
Area keeps dust-laying effect more preferable.
Further, shown in cooperation Fig. 5 and Fig. 7, nozzle 30 is prevented to be pierced by the locating part of casing 10 in installing on casing 10
21, specifically, the present embodiment preferably locating part 21 is formed from the end face of the second end of tube wall to casing inner diameter to extension, is made
The locating part 21 is annular in shape, and the internal diameter of locating part 21 is less than the outer diameter of nozzle 30.
By above-mentioned improvement, while preventing nozzle 30 to be pierced by casing 10, the water spray end of spray head is as far as possible close to spray
The outlet of mouth 30, the dust for generating spray head to 30 exit of nozzle in time are sprayed water, effectively will from source
Dust Capacity is preferably minimized, in addition, can be adapted for the device different straight since locating part 21 annular in shape has one fixed width
The nozzle 30 of diameter.
Further, casing 10 is equipped with the locking piece 22 casing 10 to be fixed to nozzle 30,22 edge of locking piece
Casing 10 is connected to radially displaceablely on the tube wall of inlet segment 14, and one end of locking piece 22 stretch to inside casing 10 with
It is resisted against the outer wall of nozzle 30, by above-mentioned locking piece 22, allows casing 10 is more firm to be sheathed on nozzle 30, prevent
It is worn caused by shaking because of the radial direction of casing 10 to nozzle 30.
Further, one end that the present embodiment is preferable on locking piece 22 inside casing 10 is fixed with shape and is matched with
The arc jacking block 23 of 30 outer wall of nozzle.By the setting of the arc jacking block 23, increase when fastening locking piece 22, locking piece 22
With the contact area between 30 outer wall of nozzle, keep locking more firm.
Further, the quantity of the preferred locking piece 22 of the present embodiment is two, and is symmetrically set in 10 radially opposite sides of casing.With
It is maintained at nozzle 30 and casing 10 in same axis, does not influence injection direction when gunite concrete, while making casing 10 can
It is sheathed on nozzle 30 with more firm.
For the key step of use process of the present invention:
1, several atomizers are flush-mounted in respectively in corresponding showerhead hole 11, water supplying pipe are connected on inlet opening 12, so
Entire sleeve 10 is inserted in nozzle 30 afterwards, and makes 21 one end of locating part close to the outlet end of nozzle 30；
2, locking piece 22 is fastened, arc jacking block 23 is made to be resisted against the outer wall of nozzle 30；
3, start gunite concrete, open simultaneously tap, pressure water is injected to casing 10 by inlet opening 12, makes to be atomized
Spray head carries out 360 degree of atomizing de-dustings in concrete of the outlet end of nozzle 30 to ejection；
4, after concrete to be sprayed, tap is closed, stops spraying, absent-mindedness locking piece 22, taking-up casing 10.
