A wet mixing and spraying machine

Abstract

The invention relates to a wet mixing and spraying integrated machine, which includes a vertical stirring device A and a vertical stirring device B with the same structure, a slurry wind conveying pipe, a driving device, a control system and a chassis. The output of the two sets of vertical stirring devices The feed ports are respectively sealed and connected with the slurry wind conveying pipe, and the driving device drives the stirring shafts of the two sets of vertical stirring devices to realize forward and reverse asynchronous rotation, and the control system realizes the control of the driving device and the switching between forward and reverse rotation. on the chassis. When working, the stirring device A rotates forward to realize the discharge wet spraying operation, and the stirring device B reverses to stir the material in the mixing tank to prepare slurry; in the next cycle, the forward and reverse switching of the stirring device is realized under the control of the control system , the mixing device B rotates forward to discharge, and the stirring device A reverses to prepare the material. This cycle realizes continuous wet mixing and spraying operation. The wet mixing and spraying machine of the present invention is small in size, light in weight and simple in structure, and is suitable for tunnels, culverts, mines, etc. Wet spraying operations in underground roadways.

Description

technical field [0001] The invention relates to the field of spraying machines, in particular to a wet mixing and spraying integrated machine. Background technique [0002] Shotcrete machine is the necessary equipment in the tunnel, culvert, and mine underground roadway operation. At present, the wet shotcrete machine used has the so-called tidal spray machine with spiral feeding and rotor dry spraying machine. This machine relies on the stirring during the spiral feeding process. It is difficult to achieve uniform mixing of materials, and it is necessary to add water at the nozzle, which is actually still a dry spraying operation; there is a wet spraying machine with a piston concrete pump and a mixer, which realizes wet spraying. However, due to the complexity, bulkiness, high cost, poor mobility, and difficulty in cleaning and maintenance of the equipment, its use in small spaces is limited. Therefore, there is an urgent need for a wet mixing and spraying all-in-one mach...
