Further, described accelerating admixture conveying device comprises the accelerating admixture delivery hose that one end is connected with spraying gun head, the accelerating admixture be connected with the accelerating admixture delivery hose other end measures and adds pump, and be arranged at accelerating admixture delivery hose and accelerating admixture measure to add between pump and with the two accelerating admixture atomizer be all communicated with.
In addition, described change gear box is connected by the first Hooks coupling universal coupling with feeding screw axle.Described feeding screw axle is connected by the second Hooks coupling universal coupling with screw rotor.
In addition, the air compressor described blast pipe is also connected with.
Preferred as one, described first Hooks coupling universal coupling and the second Hooks coupling universal coupling are universal coupling with spider.
Described screw rotor and sealed stator form supercharging gas-tight silo jointly.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) structure of the present invention is simple, and reliability is high, and small volume and less weight, energy consumption are low, and manufacturing cost is relatively low; In addition, the present invention adopts screw compulsory pumping feeding, there is not sizing problem.
(2) the present invention first adopts screw pump pumping, and adopt afterwards and add wind conveying, thus obtain higher lift and fed distance far away, ensure that can long distance delivery.
(3) the present invention is Continue displacement method feeding, and achieve concrete no pulse and evenly carry accelerating admixture is added evenly, decrease resilience, jet face is smooth closely knit, and whitewashing labor intensity of operating staff reduces; Equipment is vertical feed simultaneously, considerably increases the compliance to low slump concrete, and improves the intensity of sprayed mortar when not increasing cost.
(4) the present invention adds compressed air in concrete outlet and carries out wind and send, and greatly reduces plugging probability; And the present invention adopts screw rod large eccentricity large pitch, the slow-speed of revolution makes material good by property, thus improves high life of the present invention.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described, and embodiments of the present invention include but not limited to the following example.
Embodiment
As shown in Figure 1, a kind of new concrete wet-spraying machine, comprise motor 1, the change gear box 2 be connected with motor, the feeding screw axle 3 be connected with change gear box, feeding screw axle is contained in the stirring storage bin hopper 4 of its inside, and stirs the sealed stator 5 that is connected of storage bin hopper, and be arranged at the interior and screw rotor 6 be connected with feeding screw axle of sealed stator; Described sealed stator is also provided with mixing arrangement away from the one end of stirring storage bin hopper; Described mixing arrangement is also connected with injection apparatus.By above-mentioned setting, adopt sealed stator and screw rotor to carry out concrete conveying, effectively can prevent the problem of sizing, and be matched by feeding screw axle and sealed stator, screw rotor, thus realize continuous dislocation feeding, ensure that concrete no pulse is evenly carried.In addition, be provided with injection apparatus in concrete discharge outlet, effectively concrete can be sprayed uniformly, ensure that the effect after injection.
Further, described mixing arrangement comprises the mixing chamber 7 be connected with sealed stator, and is arranged at the blast pipe 8 be communicated with on mixing chamber and with it.By arranging blast pipe and mixing chamber; in mixing chamber, air and concrete can be mixed uniformly; and can utilize wind-force by concrete conveyance to injection apparatus by blast pipe to during mixing chamber conveying air; because intake velocity is certain; so can guarantee that concrete enters injection apparatus uniformly; avoid resilience, jet face is smooth closely knit.
