Concrete grout spraying machine

Abstract

The invention discloses a concrete grout spraying machine. The concrete grout spraying machine structurally comprises a speed reduction machine base, a shaft motion motor, a steel lining rotor base, agrout spraying material stirring roller, a hopper disc groove, a clamping column rack and a connecting pipe whirlcone. The concrete grout spraying machine applies cooperation of a brush grout extraction frame and the connecting pipe whirlcone, the effect that an extraction air flue wraps a fluid column pipe is achieved through a multi-runner left wheel sliding groove in a roller groove shell, theeffect of condensation pipe convolution is achieved, sprayed grout is erupted, meanwhile, preliminary cooling is rapidly conducted on concrete, the brush grout extraction frame achieves the guiding function in a corrugation inner way, and an equipment inner runner is maintained. By application of cooperation of a funnel grout spraying groove and the hopper disc groove, the track effect that a multi-rack propeller extraction fluid column is upwards twisted, and twisted grout spraying is developed is achieved, the grout discharging face is wide, fine-layer coverage is efficient, layer-by-layercoverage uniformity and flatness are achieved, a foundation wall face and a column body are positioned and erected through wood boards, concrete pasted plate filling, flowing and compacting are achieved through the sprayed grout, and stable grouting operation is formed.

Description

technical field [0001] The invention relates to a concrete spraying machine, which belongs to the field of concrete. Background technique [0002] Concrete is the basic raw material for building construction. It is used for laying foundations and stabilizing wall bricks. In large-scale building construction, it is often necessary to use a shotcrete machine with concrete delivery to form the operation of pouring foundation support columns and supporting walls. The continuous supply of conveying quality and spraying progress forms a close matching work. The shortcomings of the current technology that need to be optimized are: [0003] Concrete is formed by the mixing ratio of material coagulation mud and mortar with a small amount of water injection. Among them, the mud powder is relatively small, while the sand particles are too large and easy to agglomerate, which will cause the inner hard block of the mortar to be wrapped and coagulated by the mud liquid. During the proces...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a concrete spraying machine to solve the problem that concrete is formed by the mixing ratio of a small amount of water injection of material coagulation mud and mortar, among which the mud powder is relatively small, while the sand particles are relatively large and It is easy to agglomerate, which will cause the inner hard block of the mortar to be wrapped and coagulated by the mud liquid. During the conveying and spraying process, the sand ball will scratch the runner plate in the runner, and the inner wall will be pressed by the roller conveying, resulting in the outside of the runner groove. Convex deformation brings fluid sluggish residual raw material operation during the mud transportation process. After the residual raw material is air-dried, the hard lumps will interfere with the purity of the concrete. During the impact of the fluid, the agglomerated mud lumps will be mixed in, causing the wall to crack in the later stage of construction and cause safety hazards. The problem
