[0001] The utility model relates to concrete construction technical field, concretely relates to a nozzle auxiliary sprayer. BACKGROUND

[0002] In the tunnel construction, when the concrete is sprayed to the surrounding rock, in order to avoid the rebound impact of the concrete when it is sprayed to the surrounding rock by artificial, a long spraying distance is usually selected. However, when the spraying distance is long, the rock surface spraying adhesion is reduced, which causes the nozzle to be seriously splashed, resulting in wet sprayed concrete overconsumption. SUMMARY

[0003] In view of the defects in the prior art, the technical problem to be solved by the utility model is to provide a nozzle auxiliary sprayer which is simple in structure, easy to manufacture, can catch the splashed concrete and spray it out again.

[0004] In order to solve the above technical problems, the utility model adopts the following technical scheme: a nozzle auxiliary sprayer, which comprises an arc-shaped apron and an auxiliary spray pipe, the auxiliary spray pipe is fixedly installed in the arc-shaped apron, the arc-shaped apron is installed below the nozzle through a fixing piece, and the front end of the arc-shaped apron extends to the front of the nozzle outlet to catch the splashed spray material of the nozzle; a valve switch is arranged on the auxiliary spray pipe, the auxiliary spray pipe is communicated with a fan through the interface, and the high-pressure wind generated by the fan can spray the spray material in the arc-shaped apron out again.

[0005] Preferably, the fixing piece comprises a fixed plate, a fixed bolt and a pair of threaded rods, the two threaded rods are welded on the two sides of the arc-shaped apron, the fixed plate is slidably installed on the two threaded rods and is fixed by a double nut, the fixed position can be adjusted, and the adaptability is enhanced.

[0006] Preferably, the arc-shaped apron is a semicircular plate, and the front end of the arc-shaped apron exceeds the nozzle outlet by 4 cm.

[0007] Preferably, the auxiliary spray pipe is fixedly installed in the arc-shaped apron by welding.

[0008] Preferably, the valve switch is a ball valve.

[0009] Preferably, the arc-shaped apron and the auxiliary spray pipe are integrally molded rubber products, which can reduce the weight.

[0010] The utility model has the advantages that the device is arranged below the nozzle to catch the splashed spray material of the nozzle, and the spray material in the arc-shaped apron is sprayed again by high-pressure wind, which can avoid or reduce the splashed spray material, and greatly reduce the waste caused by the splashed spray material.

[0015] In order to better understand the improvement of the utility model compared with prior art, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment.

[0016] As Figure 1 The utility model discloses a spray head auxiliary sprayer, mainly by arc bucket 1 and auxiliary spray pipe 2 are formed, arc bucket 1 is installed below spray head 6 through fixed part 3 and the front end of arc bucket 1 extends to the front of the spout of spray head 6 to catch the spray anchor material that spray head 6 spills.

[0017] Arc bucket 1 is semicircular plate, and the front end of arc bucket 1 is preferably more than the spout 4cm of spray head 6.Fixed part 3 is mainly composed of fixed plate 3a, fixed bolt 3c and a pair of threaded rods 3b, two threaded rods are welded on the two sides of arc bucket 1, and the fixed plate is slidingly installed on the two threaded rods and is fixed through double-end nuts. Figure 3 As shown in the figure, the fixed plate 3a is adjusted on the two threaded rods 3b to make the arc bucket 1 can be installed on different spray heads 6, and the adaptability is high.

[0018] Auxiliary spray pipe 2 is fixedly installed in arc bucket 1 by welding, in order to reduce the weight of the device, arc bucket 1 and auxiliary spray pipe 2 can also be made by integral molding. Figure 2 As shown in the figure, the rear end of auxiliary spray pipe 2 is provided with an interface 5 with valve switch 4, auxiliary spray pipe 2 is communicated with fan through interface 5, and auxiliary spray pipe 2 sprays the spray material in arc bucket 1 again through the high-pressure wind generated by fan. The valve switch 4 is preferably a ball valve, the fan pipe is connected to the interface 5, the valve switch 4 is rotated to open the valve, and the high-pressure wind blows out from the front end of auxiliary spray pipe 2.

[0019] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
