Problems solved by technology

[0002] Concrete wet spraying machine is widely used in coal mine roadways, highway tunnels and other places that require shotcrete support. The common concrete wet spraying machine is plunger type concrete wet spraying machine. Its working principle is to realize pumping by switching the distribution valve. Due to the swing of the distribution valve during the pumping process, the pulse phenomenon during the pumping process is caused, which increases the probability of pipe plugging during the pumping process and causes the rebound problem during the spraying process

Abstract

The invention provides a non-pulse S-valve wet spraying machine, which solves the pulse problem in the pumping process of the concrete wet spraying machine. The wet spraying machine includes a frame, a pumping mechanism, a swing mechanism, a motor and a hydraulic system, and the pumping mechanism It includes a hopper, a material chamber, a concrete feeding mechanism, an auxiliary feeding mechanism and a distribution valve. The hopper is set above the material chamber. Both the concrete feeding mechanism and the auxiliary feeding mechanism include a hydraulic cylinder, a concrete piston and a concrete cylinder. The auxiliary concrete cylinders of the feeding mechanism are all connected to the material chamber, the distribution valve is an eccentric reducer, the front end is connected to the discharge port, and the rear end is equipped with a distribution valve friction plate and a rear friction plate. The swing mechanism includes a swing hydraulic cylinder, a mandrel, The base of the swing arm and the swing hydraulic cylinder, and the two ends of the mandrel are respectively connected with the swing arm and the upper part of the distribution valve. The non-pulse S-valve wet spraying machine provided by the present invention also has the advantages of high-pressure pumping, good sealing performance, no pumping pulse, and small grouting rebound.

Description

technical field [0001] The invention relates to the technical field of engineering equipment, in particular to a pulseless S-valve wet spraying machine. Background technique [0002] Concrete wet spraying machine is widely used in coal mine roadways, highway tunnels and other places that require shotcrete support. The common concrete wet spraying machine is plunger type concrete wet spraying machine. Its working principle is to realize pumping by switching the distribution valve. Due to the swing of the distribution valve during the pumping process, the pulse phenomenon during the pumping process is caused, which increases the probability of pipe plugging during the pumping process and causes the rebound problem during the spraying process. Contents of the invention [0003] In order to solve the pulse and spray rebound problems that occur during the working process of the concrete wet spraying machine, the present invention provides a non-pulse S-valve wet spraying machin...
