Concrete automatic feeding and jetting device and concrete automatic feeding and jetting method

Abstract

The invention discloses a concrete automatic feeding and jetting device and a concrete automatic feeding and jetting method, and the problem that in the prior art, the mechanization degree of concrete jetting during the construction process still needs to be improved is solved. The concrete automatic feeding and jetting device comprises a moving rack, a material collecting device, a material conveying device, a feed opening and a driving device; the liftable material conveying device is arranged in the front of the moving rack, the material collecting device is fixedly arranged at the front end of the material conveying device, the feed opening is connected to the tail end of the material conveying device, a material jetting device is fixedly arranged on the tail portion of the moving rack, the material collecting device is shaped like a barrel, a rotating shaft is fixedly arranged on the center axis of the material collecting device, the two ends of the rotating shaft are provided with reversely distributed helical blades respectively, and a material-sticking prevention device is fixedly arranged on the inner contact face of a delivery rolling wheel in an opposite mode. According to the concrete automatic feeding and jetting device and the concrete automatic feeding and jetting method, the automation degree is high, manual feeding operation is thoroughly liberated, the influences that due to the fact that concrete feeding is discontinuous due to human factors, pulses are nonuniform during the concrete jetting process are reduced, and automated operation of the concrete jetting field is really achieved.

Description

Technical field [0001] The invention relates to a concrete construction equipment and method, in particular to an automatic concrete taking and spraying device and a concrete automatic taking and spraying method. Background technique [0002] At present, concrete spraying in tunnels with large cross-sections is generally used: during wet spraying, the concrete tanker transports the mixed wet material to the wet spraying machine, and directly drops into the hopper of the wet spraying machine to start the wet spraying operation. When dry spraying, the spraying process is: the mixture of sand, stones, and cement is stirred on the ground mixer and transported to the construction section by other means such as trucks or forklifts, and the concrete is poured into the fully automatic spraying machine (patented) CN103382845B), vehicle-mounted shotcrete machine (patent number CN103883334B), walking type automatic feeding shotcrete machine device (patent number CN102677904B), shotcrete mac...
