Abstract
The utility model discloses a wet spraying machine spray head provided with two accelerating agent inlets and capable of reducing the sprayed concrete rebound rate. The spray head comprises a spray head body (1) and a material conveying hose (2) connected with the tail portion of the spray head body (1). The spray head body (1) is of a hollow tubular structure, the material conveying hose (2) is provided with a material mixing part (3) in the shape of a football, and the length of a short shaft of the material mixing part (3) is larger than the diameter of the material conveying hose (2); accelerating agent addition tubes (4) are arranged at the front end of the material mixing part (3), and the included angle between the axis of each accelerating agent addition tube (4) and the axis of the spray head body (1) is an acute angle; the two accelerating agent addition tubes (4) are arranged in an up-down mode. The wet spraying machine spray head provided with the two accelerating agent inlets and capable of reducing the sprayed concrete rebound rate has the advantages of being resistant to blocking, little in rebound and sufficient in mixing.
Description
Technical field
The utility model relates to a kind of mine apparatus, is specifically related to a kind of two accelerator entrance wet-spraying machine shower nozzles of the reduction spray concrete rebound degree spraying for concrete.
Background technology
Conventional wet concrete-spraying machine is to utilize compressed air, the concrete material mixing by certain level hydrous water gray scale, the nozzle by carrier pipe through spraying machine, ejects with very high speed, thereby being subject to form concrete supporting on spray plane, is the capital equipment in current construction of shotcrete operation.Spray concrete shower nozzle is as concrete terminal output equipment, must there is gas defence leakproof, the uniform fundamental characteristics of high-voltage-resistant anti-corrosion spray concrete, and shower nozzle mostly in the market is elongated cast, concrete mixes not thorough with accelerator, and it is too small that ejection material is dispersed face, causes rebound degree large, spray concrete face is easily caved in.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of anti-blocking, resilience is few, make mixing of materials reduce fully two accelerator entrance wet-spraying machine shower nozzles of spray concrete rebound degree.
A kind of two accelerator entrance wet-spraying machine shower nozzles that reduce spray concrete rebound degree, comprise head body and the conveying flexible pipe being connected with its afterbody, described head body is hollow tubular structure, the mixing of materials portion that is provided with rugby shape on described conveying flexible pipe, its minor axis length is greater than the diameter of described conveying flexible pipe; Front end in described mixing of materials portion is provided with accelerator adding tube, and the angle between the axis of described accelerator adding tube and the axis of described head body is acute angle; Described accelerator adding tube is upper and lower two.
Two accelerator entrance wet-spraying machine shower nozzles of reduction spray concrete rebound degree described in the utility model, the angle between the axis of wherein said accelerator adding tube and the axis of described head body is 30 degree.
Two accelerator entrance wet-spraying machine shower nozzles of reduction spray concrete rebound degree described in the utility model, the front end of wherein said head body is fixed with spray concrete plate, is evenly distributed with multiple spray orifices on it.
Two accelerator entrance wet-spraying machine shower nozzle differences from prior art that the utility model reduces spray concrete rebound degree are:
Two accelerator entrance wet-spraying machine shower nozzles of reduction spray concrete rebound degree described in the utility model expand the internal diameter of the conveying flexible pipe near shower nozzle afterbody, make it to be rugby shape spheroid, accelerator adding tube is connected to the front end of described rugby shape spheroid, and the axis of accelerator adding tube and the axis of shower nozzle are acute angle; This design is in order to increase blending space, fully mix concrete and accelerator, and the axis of accelerator adding tube and shower nozzle axis be designed to after acute angle, and accelerator is more easily by swiftly flowing concrete fluid inhalation spray head pipeline, and resilience is few; Shower nozzle described in the utility model has multiple spray orifices, makes the concrete of ejection more even; Two accelerator entrance wet-spraying machine shower nozzles of reduction spray concrete rebound degree described in the utility model are provided with upper and lower two accelerator entrances, concrete enters Mixed Zone with accelerator with contrary direction, and formation liquidates, and can fully mix, guarantee that concrete can evenly mix, rapid solidification.
Below in conjunction with accompanying drawing, two accelerator entrance wet-spraying machine shower nozzles of reduction spray concrete rebound degree described in the utility model are described further.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model reduces two accelerator entrance wet-spraying machine shower nozzles of spray concrete rebound degree.
The specific embodiment
Embodiment 1
As shown in Figure 1, two accelerator entrance wet-spraying machine shower nozzles of reduction spray concrete rebound degree described in the utility model, comprise head body 1 and the conveying flexible pipe 2 being connected with its afterbody, described head body 1 is hollow tubular structure, the mixing of materials portion 3 that is provided with rugby shape on described conveying flexible pipe 2, its minor axis length is greater than the diameter of described conveying flexible pipe 2; Front end in described mixing of materials portion 3 is provided with accelerator adding tube 4, and the angle between the axis of described accelerator adding tube 4 and the axis of described head body 1 is acute angle; Described accelerator adding tube 4 is upper and lower two, and the front end of described head body 1 is fixed with spray concrete plate, is evenly distributed with multiple spray orifices on it, can make the concrete of ejection more even.
Preferably, the angle of the axis of the axis of described accelerator adding tube 4 and described head body 1 is 30 degree, and now mixed effect is best.
Shower nozzle described in the utility model can make concrete better spread out, and is ejected into more equably on metope, can reduce bounce-back rate, also can hold better the thickness that spray concrete forms on the inwall of tunnel.
The mixing of materials portion 3 of rugby shape described in the utility model has expanded the blending space of material, fully mix concrete and accelerator, and after the axis of accelerator adding tube 4 and head body 1 axis designs acutangulate, accelerator is more easily by swiftly flowing concrete fluid inhalation spray head pipeline.
Above-described embodiment is described preferred embodiment of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
Claims (3)
