Highly-effective energy-saving chain type concrete spraying machine

Abstract

The invention provides a high-efficiency energy-saving chain-type concrete injector, which comprises an underpan, a hopper, a gear reducer, a driving chain wheel, a driven chain wheel, a piston cylinder and pistons that are connected in series. The driving chain wheel is connected with a power output shaft of the gear reducer and horizontally arranged on the right end of the underpan; the shaft bottom end on the driven chain wheel is horizontally mounted on the left end of the underpan through the bearing support; the driven chain wheel on the mixer is coaxially arranged inside the hopper; the driven chain wheel and the mixer inside the hopper are separated into two vertically-arranged feeding chambers by a partition board; the partition board is arranged with a down-flow port on one side; between the driving chain wheel and the driven chain wheel, the piston cylinder and the purging cylinder are arranged horizontally; the pistons in serial connection are connected with the chain in serial mode, and linked to the driving chain wheel and the driven chain wheel through the piston cylinder and the purging cylinder; the piston cylinder is arranged with an air intake and a grout injection port (nozzle); the purging cylinder is arranged with a water injection pipe and a water outlet.

Description

technical field [0001] The invention relates to engineering machinery equipment, in particular to a high-efficiency energy-saving chain concrete sprayer integrating conveying and pouring. Background technique [0002] Concrete spraying machines are widely used in hydropower projects, underground tunnels, culverts, subway projects, and shotcrete reinforcement construction operations in coal mines and high marshes mine roadways. [0003] At present, there are about six types of concrete sprayers at home and abroad: double-tank type, screw type, drum type, extruded hose type, and rotor type. The first four have been screened by long-term application and have withdrawn from the market. [0004] Rotor-type products are the most widely used today. Domestic products include Pz5 dry spraying machine and HPc6 wet spraying machine. Foreign products include Furukawa dry spraying machine from Japan and Aliwa wet spraying machine from Switzerland. [0005] The rotor type concrete spray...

AI Technical Summary

Problems solved by technology

[0005] The rotor type concrete spraying machine widely used in the market has obvious defects in the use of the plane gap seal. The rotor type spraying machine is a constant pressure forced friction seal, the seal is not reliable, the seal is difficult to replace, and the energy consumption is high. , large dust, high operating cost, short service life, the service life is only 50-70 hours
