Abstract

The utility model discloses a shotcrete machine which is a main construction machine for supporting shotcrete. The shotcrete machine is used for directly spraying concrete mixture to a sprayed surface thereby performing a supporting function for surrounding rocks. Based on the traditional rotor type concrete spraying machine, a novel shotcrete machine is formed through adding a new device which is characterized in that: a water atomizer is added on the rotor spraying machine; the concrete is changed from dry material at a material inlet to wet material at a material outlet, thereby reducing dust and improving aggregation performance of the sprayed concrete; and the special design of the water adding pipe has the following functions: improving penetration power of water, reducing amount of water for mixing, uniformly wetting the concrete mixture, preventing aggregation or pulse, and improving spraying continuity. Simultaneously, because the dry power is loaded, early hydration of the cement is reduced, and reaction efficiency between concrete and accelerator is improved. Higher quality of the sprayed concrete is obtained, and the dust at the periphery of the shotcrete machine is greatly reduced.

Description

A kind of concrete spraying machine
Technical field
The utility model relates to a kind of new concrete wet shot machine, belongs to the main construction machinery of concrete spraying support.
Background technology
Concrete spraying support is as a kind of advanced person's construction technology, extensive use in mine, tunnel, subway, geotechnical engineering and infrastructure construction.As the main construction machinery of concrete spraying support, the rotator type concrete sprayer is to use both at home and abroad at present maximum a kind of types, but mainly is to be main with the dry type concrete spraying machine.The dry type concrete spraying machine is to be prepared burden cement, sand, the stone compound of the certain proportioning that mixes by rotor; Deliver to shower nozzle with compressed air through conveying pipeline; Add water again and be sprayed onto on the working face, the construction operation dust concentration is high, resilience is big, and sprayed concrete strength is not high.
For addressing these problems, some concrete sprayer manufacturers are being devoted to develop wet concrete sprayer both at home and abroad.Wet concrete sprayer is to be prepared burden concrete mix (cement+sand+stone+water) by mixing station, delivers to shower nozzle with compressed air through conveying pipeline, directly is sprayed onto on the working face.Such job practices, water are mixed thoroughly in the mix in advance, and dust concentration is low, resilience is little, and sprayed concrete strength is high.But existing in the market wet concrete sprayer material loading is inconvenient, and concrete disintegration just appearred in the shower nozzle place when fed distance was long, and resilience strengthens, and influences sprayed concrete strength; Hydration reaction takes place in mix too early, and is low at shower nozzle place and accelerating admixture joint efficiency.
Summary of the invention
The purpose of the utility model provides a kind of new concrete wet shot machine, and it can guarantee effectively when concrete sprays that dust concentration is low, resilience is little, sprayed concrete strength is high.
The technical scheme of the utility model is following:
Hopper is connected through support bar with elastic base; Be installed on the rotor then; The discharging elbow is installed on the lower base, and deceleration device, drive unit are installed on the pedestal, and airduct is split into first airduct and second airduct through valve control; Adding water atomizer(-iser) is to be formed by connecting through snap joint in the consistent atomizer of two calibers, and is connected with airduct through the flange at two ends.
Add water atomizer(-iser) by built-in plastics of cover or a rubber parts, the outside steel pipe sleeve that closely puts the band filler pipe is formed, and electrolysis unit is installed on the filler pipe.
Adding water atomizer(-iser) is the same set composite of a cover two ends internal diameter.
Snap joint is connected to the arbitrary place of spraying machine blast pipe or discharging opening place or hopper place, near spraying machine.
The described water atomizer(-iser) that adds is installed on discharging elbow or the hopper.
The utility model is because only need on original rotor spraying machine, to add water atomizer(-iser), electrolysis unit, and devices such as measuring pump are so implement fairly simple; The use of this device simultaneously can guarantee that effectively dust concentration is low, resilience is little, sprayed concrete strength is high during delivering concrete.
Description of drawings
Fig. 1 is a wet shot machine profile sketch map;
Fig. 2 is a wet shot machine work structuring sectional view;
Fig. 3 adds the water atomizer(-iser) sectional view;
Fig. 4 is the electrolysis unit sketch map;
Below in conjunction with accompanying drawing the content of the utility model is done further explain.
The specific embodiment
Shown in accompanying drawing, infundibulate hopper 2 resiliency supported are on hopper base 13, and dried mix evenly falls into the material chamber 15 of rotor block 3 through the feed opening of hopper 2.Rotor block 3 is behind Rotate 180 under the drive of drive unit °; The material chamber 15 of filling the concrete material is communicated with discharging elbow 4; At this moment feed compressed air by a place and blow into discharging elbow 4 to the concrete material through air inlet port 14; Herein, the concrete material mixes with atomized water, then be delivered to together under the effect of air-flow conveying pipeline again the nozzle place be sprayed onto work plane after liquid accelerator mixes.The atomized water here is to add 7 ejections of water atomizer(-iser) by what add between compressed air hose 5 and the discharging elbow 4.This adds water atomizer(-iser) 7 is by cover built-in plastics or a rubber parts, and the outside steel pipe sleeve 18 that closely puts band water injection hole 20 is composited, and is as shown in Figure 3, adds the snap joint 16 of water atomizer(-iser) 7 through two ends and links to each other with compressed air hose 5; Water injection pipe 20 inside are equipped with electrolytic water device 11, and wherein 21 represent electrode bars, 22 expression batteries (as shown in Figure 4).Outer water tube is through linking to each other with water injection pipe 20 and water being injected in the atomizer 7.Because the pressure in blast pipe or the conveying pipeline; The water that can will inject atomizer arrangement becomes atomized water through aperture 19 suction lines; This device does not require the hydraulic pressure that injects, and still can normally join in airduct or the conveying pipeline road during less than blast at hydraulic pressure, and this device can change into the dried mix mixing water in atomized water and the conveying pipeline and be wet concrete; Again with the accelerating admixture effect rapid hardening at nozzle place.
Add water atomizer(-iser) by two parts component, inside is to form with plastics or rubber injection mold, and towards the aperture of 1mm-5mm, the outside is the steel pipe sleeve that is welded with filler pipe identical with its external diameter on its tube wall.This device is connected on blast pipe or discharging opening or the hopper with snap joint.Because the pressure in blast pipe or the conveying pipeline can become atomized water through the aperture suction line with the water that injects this device, this device does not require the hydraulic pressure of injection, still can normally join in airduct or the conveying pipeline road during less than blast at hydraulic pressure.This device can become wet concrete with dried mix aquation in atomized water and the conveying pipeline, again with the liquid accelerator effect rapid hardening at nozzle place.
