Description

Integral concrete spraying device

technical field

The invention relates to a motorized grouting device used for roadway support in coal mines, mines, water conservancy, tunnels and the like. the

Background technique

The shotcrete machine used in underground coal mines is generally shotcrete (a mixture of cement, stone, sand, and powdered quick-setting agent) which is manually mixed and directly added to the feeding port of the shotcrete machine, so that not only the dust in the roadway The quantity is large, and the labor intensity of the workers is high. At the same time, due to the manual mixing, the composition of the sprayed material is not uniform. The uniformity of the sprayed material from the spray gun of the shotcrete machine is very poor, and the rebound rate is very high. It directly affects the large roadway support. the quality of. the

At the same time, the existing spraying device is simply placed in the working area. With the spraying operation, the spraying surface gradually moves away from the spraying device, so it is necessary to manually move the spraying device to a new position again. Long and narrow, it may be necessary to move the spraying device several times, which undoubtedly further increases the labor intensity and workload. the

Contents of the invention

The present invention aims at problems such as uneven mixing of sprayed materials, high rebound rate, large dust of working flour and poor maneuverability in the prior art, and provides an integral concrete spraying device. The present invention combines the concrete spraying machine and the mud mixer The products are transported to the spray head respectively, and the equipment is placed on a car body, which has the advantages of good maneuvering effect, low labor intensity of workers, uniform mixing of spray materials, low rebound rate, and small dust of working flour. the

To achieve the above object, the present invention adopts the following technical means:

An integral concrete spraying device, comprising at least one car body, the car body is provided with a concrete sprayer, a matching mud mixer and a mud pump; the outlet of the concrete sprayer and the outlet of the mud pump are respectively connected to the sprayer The spray head is connected with a spray gun at the front end of the spray head for the shotcrete machine.

Further, a powder quick-setting agent adder is connected with the concrete sprayer. the

Further, the vehicle body is provided with a cement rack corresponding to the mud mixer. the

Further, the concrete sprayer, the supporting mud mixer and the mud pump are located at both ends of the vehicle. the

Further, the mud pump is fixed on the cement rack. the

the

Operating principle and working process of the present invention are as follows:

In the present invention, the concrete spraying machine, the supporting mud pump and the mud mixer are placed on a moving car body, which improves the mobility of the spraying device. , you only need to move the car body towards the direction close to the spray surface.

At the same time, this spraying device adds stone and sand to the concrete spraying machine, adds cement to the mud mixer, and inputs the two into the nozzle of the spraying machine respectively, and finally sprays them out through the spray gun, thus completely solving the problem. The dust problem has been solved, and the construction environment has been optimized. the

A powdered quick-setting agent adder is installed at the inlet of the concrete sprayer, which can add the quick-setting agent into the sprayer, which improves the adhesion between the two, makes it evenly mixed and reduces the rebound phenomenon.

Jet machines, mud pumps and mud mixers are located at both ends of the car body, so that the weight can be optimally distributed on the car body as much as possible, and the force on the car body is more uniform. the

In summary, compared with the prior art, the present invention has the following obvious advantages:

1. Shotcrete machine, powder accelerator and cement slurry pump are integrated, which is very convenient to transport and use.

2. The powder accelerator is added automatically, and the amount added is guaranteed. the

3. Because the "spray head for spraying machine" is equipped with a mixing device, the material sprayed by the spray gun of the present invention is very uniform and the spray effect is good. the
