Abstract

The utility model relates to a discharging device of a wet sprayer for concrete, which is particularly suitable for column piston enforced uniform feed type concrete wet sprayers. The utility model has a discharge barrel (1) connected with the discharge port of the wet sprayer. The two ends of the discharge barrel are respectively an air inlet pipe joint (2) and a discharge nozzle joint (4). A non-metal adhering-proof liner (3) is sheathed in the discharge barrel. The discharging device has a function of adhered mortar self-cleaning and can automatically clear the mortar adhered to the inner wall of the discharging device, effectively solving the problems of rough discharge and discharging block due to adhered mortar in the process of discharging of the wet sprayer.

Description

The concrete spraying machine discharger

The utility model relates to a kind of concrete spraying machine discharger, is specially adapted to plunger and forces even feeding type concrete spraying machine.

For solving dust concentration problems of too in the concrete sprayer course of work, improve working environment, at present, bolt-spary supports device fabrication producer is developing and is promoting concrete spraying machine.Applicant's application number promptly provides a kind of " plunger is forced even feeding type concrete spraying machine " for 96241088.8 patent application.Because the concrete that enters the wet shot machine and spray from the wet shot machine is a wet feed, and wet feed has bigger adhesiveness than siccative or tide material, therefore must consider to overcome the sticking problem of concrete mortar in particularly discharging process of wet shot machine inside, to avoid causing the smooth or obstruction of discharging, effective solution is not arranged as yet at present.

The purpose of this utility model promptly provides a kind of concrete spraying machine discharger, with the sticking problem of mortar in the solution discharging process, thereby avoids the smooth and obstruction of discharging.

The purpose of utility model realizes by following mode.

The concrete spraying machine discharger has a discharge barrel that is connected with wet shot machine discharging opening, and two of discharge barrel is respectively blast pipe joint and discharge nozzle joint, is with cover in the nonmetal anti-adhesion in the discharge barrel.

When the wet shot machine was worked, mortar 4 discharging openings were transfused to discharger, and the high-pressure blast that enters through one of discharger also is pressed into discharger simultaneously, and mortar is pressed into discharge nozzle, delivers to working face.Owing to be with cover in the nonmetal anti-adhesion in the discharge barrel, simultaneously because the continuous impact of high-pressure blast, thereby the mortar that puts in sticking to is come off automatically, play self clean-up action.

The concrete spraying machine discharger that the utility model provides, has the mortar of adhesion self-cleaning function, can remove the attached mortar that is bonded on the discharger inwall automatically, overcome effectively in the wet shot machine discharging process and caused the not smooth or blocking problem of discharging because mortar adheres to.

Below in conjunction with accompanying drawing the utility model is described in detail.

Accompanying drawing is the structural representation of the concrete spraying machine discharger that provides according to the utility model.

Discharger has a discharge barrel (1) that is connected with wet shot machine discharging opening as shown in drawings, and two of discharge barrel is respectively blast pipe joint (2) and discharge nozzle joint (4), is with cover (3) in the nonmetal anti-adhesion in the discharge barrel.

Interior cover (3) is the abrasive rubber cover, and between interior cover and the discharge barrel inwall 1-4 mm clearance is arranged.Since between interior cover and the barrel certain interval is arranged, constantly vibration under the impact of high-pressure blast, and therefore the mortar that sticks on the discharger inwall can come off automatically.Gap generally speaking between cover and the barrel is 2 millimeters.

Interior cover (3) also can adopt polyurethane material to manufacture, and between the discharge barrel inwall 1-4 mm clearance can be set, so that interior cover can produce vibration, thereby makes discharger have the mortar self-cleaning function.

Interior cover (3) also can adopt the supra polymer engineering plastics, and this material itself has the anti-preferably performance that adheres to, and can play self clean-up action.

Claims

1, a kind of concrete spraying machine discharger, a discharge barrel (1) that is connected with wet shot machine discharging opening is arranged, two of discharge barrel is respectively blast pipe joint (2) and discharge nozzle joint (4), it is characterized in that: be with cover (3) in the nonmetal anti-adhesion in the discharge barrel (1).

2, by the described discharger of claim 1, it is characterized in that: interior cover (3) is the abrasive rubber cover, between interior cover and the discharge barrel inwall 1-4 mm clearance is arranged.
