Abstract

The invention discloses a wet spraying machine double-head discharging device. The wet spraying machine double-head discharging device comprises a main pipe communicating with a concrete conveying pipeline. Two branch pipes communicating with the main pipe are fixedly arranged on the main pipe, the two branch pipes and the main pipe form a Y-shaped structure, air-material mixers are arranged at discharging ends of the branch pipes correspondingly, and the included angle alpha between the central axis of each air-material mixer and the central axis of the corresponding branch pipe is an acute angle; each air-material mixer comprises an air inlet and a discharging port which are formed in the two ends of each air-material mixer correspondingly in the axial direction, a feeding port is formed in the position, between the air inlet and the discharging port, of each air-material mixer, and the feeding port of each air-material mixer is connected with the discharging end of the corresponding branch pipe; and the two air-material mixers are distributed in a V shape, the discharging ports of the two air-material mixers are both located at one end of a flaring, and flow adjusting structures are arranged on the branch pipes correspondingly. According to the wet spraying machine double-head discharging device, the air-material mixers can be freely and flexibly switched to control the concrete spraying amount according to the demand quantity of man-hours and working conditions, and the requirement for diversified production of users is met.

Description

technical field [0001] The invention relates to the technical field of concrete wet spraying machines, in particular to a double-head discharge device for wet spraying machines. Background technique [0002] Concrete wet spraying machine is mainly used in engineering construction. Its basic principle is to use hydraulic pressure to transport the ready-mixed concrete to the air mixer through the pipeline, and use the energy of compressed air to spray the concrete at high speed to the sprayed surface. After setting and hardening, the concrete support layer is formed. [0003] The existing concrete spraying machine has the following defects: the original discharge and spray pipeline cannot adjust the discharge flow rate, and the discharge of wet sprayed concrete cannot be effectively controlled according to the pouring position and demand. Contents of the invention [0004] In order to solve the problems in the prior art, the present invention provides a double-head discharg...
