The spray gun of pulp shooting machine
Technical field
The utility model relates to the pulp shooting machine field, relates in particular to a kind of spray gun that is used for spraying on the pulp shooting machine mud.
Background technology
Pulp shooting machine is mainly used in the engineerings such as construction site, house factory tall building, tunnel, highway, bridge, protects in their surface sprinkling one deck cement mortar.
In the use of pulp shooting machine, manually hold spray gun, spray gun is sprayed onto surface of wall with mortar under the effect of air pressure and hydraulic pressure.Traditional pulp shooting machine spray gun is not blocked, and can not suppress the splash of mortar.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, provides a kind of and can reduce the construction dust concentration, and the spray gun of the pulp shooting machine that air jet pipe is fixing.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of spray gun of pulp shooting machine, comprise that nozzle, bend pipe shake hands and air jet pipe, the end that described bend pipe is shaken hands fixedly is communicated with nozzle, its other end is provided with hose coupling, and the junction of shaking hands with nozzle at bend pipe is provided with splashing board; Shake hands by bend pipe and place in the nozzle in the gas outlet of described air jet pipe, the air inlet of air jet pipe places outside bend pipe shakes hands.
According to another embodiment of the present utility model, comprise that further described splashing board is a butterfly structure, described splashing board is fixedly welded on bend pipe shakes hands.
According to another embodiment of the present utility model, comprise further on the described air jet pipe control valve is installed that described control valve is arranged on air jet pipe and the bend pipe contact position of shaking hands.
According to another embodiment of the present utility model, the air inlet that further comprises described air jet pipe is connected with and connects air valve, and the described air valve that connects is connected with the air inlet of air jet pipe by rubber linking tube.
According to another embodiment of the present utility model, comprise that further the described air valve that connects is provided with gripper shoe, an end of described gripper shoe by nut with connect air valve and fixedly connected, its other end is welded on bend pipe shakes hands.
Beneficial effect: the utility model has solved the defective that exists in the background technology, by having adopted the splashing board technology, has reduced the construction dust concentration, and adopts gripper shoe to be fixed to above bend pipe shakes hands air jet pipe, makes injection more stable.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of preferred embodiment of the present utility model.
Wherein: 1, nozzle; 2, bend pipe is shaken hands; 3, air jet pipe; 4, splashing board; 5, hose coupling; 6, control valve; 7, connect air valve; 8, rubber linking tube; 9, gripper shoe.
The specific embodiment
As shown in Figure 1, a kind of spray gun of pulp shooting machine, comprise that nozzle 1, bend pipe shake hands 2 and air jet pipe 3, the end that bend pipe is held 2 hands fixedly is communicated with nozzle 1, its other end is provided with hose coupling 5, shaking hands at bend pipe 2 is provided with splashing board 4 with the junction of nozzle 1, and splashing board 4 is a butterfly structure, and splashing board 4 is fixedly welded on bend pipe and shakes hands on 2.Shake hands by bend pipe and 2 place in the nozzle 1 in the gas outlet of air jet pipe 3, the air inlet of air jet pipe 3 places bend pipe to shake hands outside 2, the air inlet of air jet pipe 3 is connected with and connects air valve 7, connects air valve 7 and is connected with the air inlet of air jet pipe 3 by rubber linking tube 8, connects air valve 7 and is provided with gripper shoe 9; One end of gripper shoe 9 by nut with connect air valve 7 and fixedly connected, its other end is welded on bend pipe and shakes hands on 2; Control valve 7 is installed on the air jet pipe 3, and control valve 7 is arranged on air jet pipe 3 and bend pipe 2 contact positions of shaking hands.
Reasonable improvement of the present utility model has increased splashing board 4 on the spray gun, effectively suppressed splashing of mortar, has reduced the construction dust concentration, thereby produces not only practical but also can regulate the spray gun that various cement mortar are used.Connecing on the air jet pipe 3 gripper shoe 9 is installed on the air valve 7, makes air jet pipe 3 can arbitrarily not shake, spray more stable because air pressure is excessive.
Should be appreciated that specific embodiment described above only is used to explain the utility model, and be not used in qualification the utility model.Conspicuous variation of being extended out by spirit of the present utility model or change still are among the protection domain of the present utility model.
