A push-chain concrete sprayer

Abstract

A push chain-type concrete spraying machine, related to the technical field of concrete spraying equipment, comprising a machine frame (1), a traveling mechanism (3), a slurry spraying mechanism (2), a spiral feeding mechanism (4), and a hydraulic mechanism (5). The traveling mechanism and the machine frame are fixed. The slurry spraying mechanism is provided on the machine frame. The spiral feeding mechanism is connected to a hopper (207) of the slurry spraying mechanism. The traveling mechanism comprises a continuous track (31). A chain (205) is provided between an active sprocket base (201) and a passive sprocket base (202) of the slurry spraying mechanism. Pistons (206) are evenly distributed on the chain. The chain and the pistons run through cylinders (208) fixed on a cylinder supporting base (211). The spiral feeding mechanism comprises a feeder base (41), a feeder tank (42), a main spiral shaft (43), a feeding spiral shaft (44), and a material compartment (45). The feeder tank is fixed on the feeder base. The main spiral shaft is provided within the feeder tank. The feeding spiral shaft is provided at the bottom part of the material compartment. Different screw pitches and leads are designed on the main spiral shaft and the feeding spiral shaft. The spraying machine implements the functions of proportioning, mixing, feeding, and concrete spraying and has the advantages of mobile flexibility and structural compactness.

Description

technical field [0001] The invention relates to the technical field of concrete spraying equipment, in particular to an all-in-one concrete spraying machine with push-chain feeding. Background technique [0002] Concrete spraying is inseparable from the construction of coal mine roadways, railways, and tunnels. At present, the concrete spraying machines used in the concrete spraying process mainly include rotor type, rotor piston type, plunger type and push chain type, but there is no concrete spraying machine at present. A jetting machine that integrates proportioning, mixing, feeding and spraying. Most concrete jetting machines use manual proportioning, manual mixing or mixer mixing, and then manual feeding. This feeding method is time-consuming and laborious, and the construction personnel The labor intensity is relatively high, and the process of moving the machine is difficult due to the heavy weight of the concrete spraying equipment. Therefore, the market needs a con...
