Embodiment Construction

[0006] The present invention will be further described in conjunction with the accompanying drawings. First, the conical stirring cage and the vertical stirring cage are rotated by the power source to enter the working state, and then the high-pressure air valve is opened to allow the high-pressure airflow to enter from the left end of the spray pipe. The above preparatory work can be completed Pour the well-mixed concrete material from the feed port, and the concrete is pushed to the small end of the cone sleeve of the mixing cage under the push of the spiral blade of the conical mixing cage, and then sent into the discharge box. When the concrete in the discharge box reaches the After a certain amount, it is squeezed into the upper end of the vertical mixing cage, and under the push of the vertical mixing helical blade, the concrete is sent down into the injection pipe, and the concrete is sprayed from the right end of the injection pipe by the high-pressure airflow at the lef...

Abstract

The invention is a mixing cage-type wet shotcrete machine, relating to constructional engineering machinery, characterized in that the lower part of a feed hopper is connected with the big end of a mixing cage taper bush, the small end is connected with a discharge tank, the discharge tank is connected with the upper end of a vertical mixing cage cover, and the lower end is connected with the middle of a jet pipe. And the concrete enters through the feed hopper, enters the discharge tank under the drive of spiral vanes of a taper mixing cage and then enters the upper end of the vertical mixing cage, and then enters the jet pipe under the drive of spiral vanes of a vertical mixing cage, and here, the high pressure air at the left end of the jet pipe enters and jets out concrete grout from the right end of the jet pipe onto a working surface. And its advantages: the space of its spiral vanes is large and convenient to continuously push concrete grout with aggregate; its structure is simple, convenient to move and occupies a little space, easy to maintain; and its manufacturing cost is lower.

Description

technical field [0001] The invention belongs to the field of construction engineering machinery, in particular to a spraying machine for wet spraying concrete. Background technique [0002] At present, concrete spraying machines at home and abroad are divided into dry spraying machines, tidal spraying machines and wet spraying machines. Due to the large dust, high rebound and poor spraying quality of dry spraying machines and tidal spraying machines during spraying operations, they are gradually replaced by wet spraying machines. machine replaced. The screw pump structure and extrusion structure in the wet spraying machine are only suitable for conveying mortar without aggregates, and cannot transport concrete containing aggregates; the rotor wet spraying machine has concrete aggregates that are easy to be kneaded, and the mechanical mechanism of the mechanism The wear is serious and the price is high; the cylinder plunger type wet spray machine is large in size, inconvenie...
