In figure, 1: semi-circular shape injection spray pipe; 2: fog-spray nozzle; 3: water inlet; 4: outer protective cover; 5: interior protective cover.
Detailed description of the invention
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but can not be used for limiting scope of the present utility model.
In description of the present utility model, it should be noted that, term " " center ", " longitudinal direction ", " transverse direction ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.In addition, term " first ", " second " only for describing object, and can not be interpreted as instruction or hint relative importance.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, concrete condition the concrete meaning of above-mentioned term in the utility model can be understood.In addition, in description of the present utility model, except as otherwise noted, the implication of " multiple " is two or more.
As shown in Figure 1, the fully-mechanized digging machine external spraying device of the present embodiment comprises: semi-circular shape injection spray pipe 1, and semi-circular shape injection spray pipe 1 is provided with multiple fog-spray nozzle 2, and in the present embodiment, the quantity of fog-spray nozzle 2 is preferably 10, and 10 fog-spray nozzles 2 are evenly distributed along the circumference of the yellow shape injection spray pipe 1 of semicircle, instead of 8 fog-spray nozzles of the prior art, enhance atomization density, depositing dust effect is more obvious, simultaneously, fog-spray nozzle 2 can have workman's welding production, and it is convenient that fog-spray nozzle 2 is dismantled, and is beneficial to repair and replacement.
