Technical field
The present invention relates to a kind of suction type concrete spraying unit, belong to the building machinery technical field.
Background technology
Concrete sprayer is widely used a kind of construction equipment in the fields such as underground construction, geotechnical engineering; It utilizes compressed air as power, with the mix of certain proportion configuration, through pipeline; High velocity jet is to receiving on the spray plane and setting and harden, thereby forms concrete supporting.Concrete sprayer is divided into dry spraying machine and wet shot machine by the water content of institute's spraying of material, and the dust concentration on dry spraying machine side is big, the injection resilience is many, and work situation is very abominable, material is wasted and supporting quality is poor; So dry spraying machine is replaced by the wet shot machine gradually; The wet shot machine overcomes or partly overcomes the shortcoming of dry spraying machine, has reduced dust concentration, has improved workman's condition of labor; Improved supporting quality; But still exist following problem: mostly domestic wet shot machine is rotator type, exists wear liner serious, the sealing difficulty; Artificial batching can not guarantee the concrete quality, finally influences supporting quality; Material loading, proportioning, stirring, conveying and injection lack integrated, and efficiency of construction is low.
Summary of the invention
To the problem that above-mentioned prior art exists, the present invention provides a kind of suction type concrete spraying unit, and compact conformation is reasonable, operating principle is advanced, integrate batching, stirring, conveying, injection are multi-functional; Improve workman's condition of work; Reduce labor strength, batching can accurately be regulated, and supporting quality is stable; High efficiency controls easy.
To achieve these goals; The technical scheme that the present invention adopts is: a kind of suction type concrete spraying unit; Comprise strength delivery injector, frame, base, the strength delivery injector is fixed on the base of frame, comprises hopper, bracing frame, airduct seat; The strength delivery injector also comprises Venturi tube, and suction type concrete spraying unit also comprises spiral batching mixing plant; Venturi tube is fixed on the bracing frame on the base, and is connected with the airduct seat through the short pipe of its rear end welding, is connected with hopper through the short pipe of its rear end perpendicular to axis direction again simultaneously; Spiral batching mixing plant is made up of driving mechanism, mixed-hopper, sand hopper, helical stir axle, cement hopper, bearing, bearing cover; Driving mechanism comprises transmission mechanism, shaft coupling, reductor, motor; Motor is fixed on the base; Helical stir axle two ends are placed in the mixed-hopper by bearings, sand hopper, cement hopper be positioned at the helical stir axle the top of mixed-hopper at one end.
The helical stir axle is the Reducing screw shaft, can select different screw pitches for use according to the requirement of charge ratio.
Transmission mechanism is a belt gear.
Increased spiral batching mixing plant; Therefore with before compared with techniques, this concrete spraying unit compact conformation is reasonable, operating principle is advanced, integrate batching, stirring, conveying, injection are multi-functional, improves workman's condition of work; Reduce labor strength, batching can accurately be regulated; Adopt Venturi tube to be used for strength and carry, pressure reduction is big, and precision is high, good stability, and supporting quality is stable, and high efficiency controls easy.
