Abstract

A cage-stirring concrete wet spraying machine related to construction machinery, characterized in that the bottom of the feed hopper (1) is connected to the large end of the cage-stirring cone sleeve (2), and its small hole is communicated with the discharge box (5). The hopper is communicated with the upper end of the vertical cage cover (4), and the lower end is communicated with the middle part of the injection pipe (7). Concrete is fed from the feed hopper, pushed by the conical mixing cage (3) helical blade, enters the discharge box, and then enters the upper end of the vertical mixing cage sleeve, and enters the injection pipe under the push of the vertical mixing cage (6) helical blade At this time, the high-pressure air from the left end of the injection pipe enters, and the concrete slurry is sprayed out from the right end of the injection pipe and sprayed onto the working surface. Its advantages are that the helical blade has a large space, which is convenient for continuously pushing the concrete slurry with aggregate, the equipment structure is simple, the movement is convenient, the space occupied is small, the maintenance is easy, and the cost is low.

Description

Stirring cage wet spraying machine

technical field

The invention belongs to the field of construction engineering machinery, in particular to a spraying machine for wet spraying concrete.

Background technique

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 Severe wear and tear, and the price is high; the cylinder plunger type wet spray machine is large in size, inconvenient to transport, and the maintenance of the hydraulic system is complicated, and the price is higher. For this reason, the present invention provides a concrete wet spraying machine with a cage-stirring structure that is simple in structure, easy to move, takes up little space, feeds continuously, and is easy to maintain.

Contents of the invention

The bottom of the feed hopper (1) is connected to the large end of the cage-stirring cone sleeve (2), the conical stirring cage (3) is installed in the cage-stirring cone sleeve, and the small end of the cage-stirring cone sleeve communicates with the discharge box (5). The discharge box communicates with the upper end of the vertical cage cover (4), and the vertical cage cover (6) is installed in the vertical cage cover, and the vertical cage cover below communicates with the middle part of the injection pipe (7).

The advantages of the present invention are that the volume of the working space of the spiral blades of the mixing cage is large, which is convenient for conveying and advancing the concrete containing aggregates, and the mixing cage with the structure of the spiral blades has continuous feeding, simple structure, convenient movement, small occupied space, easy maintenance and low cost. lower.

Description of drawings

Figure 1 is a schematic diagram of the structure of the cage-stirring wet spraying machine.

Detailed ways

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 left end of the injection pipe. Get out and get the concrete sprayed onto the work surface through the hose and nozzle. After the work is completed, first stop the feeding, and after the concrete is basically drained, turn off the power source, and then turn off the high-pressure air valve.
