MATERIAL CONVEYING TRANSITION MECHANISM, PUMPING DEVICE, AND SPRAYING APPARATUS

WIPO Patent Application WO/2023/087983

A1

A material conveying transition mechanism, a pumping device, and a spraying apparatus. The material conveying transition mechanism (21) comprises: a device body (100) provided with an accommodation space and a feeding port (I) and a discharging port (II) which are in communication with the accommodation space; and an elastic energy storage member (200) arranged inside the accommodation space, wherein the elastic energy storage member (200) is configured to be compressed by slurry and deform to store elastic potential energy when the slurry enters through the feeding port (I), and to release the elastic potential energy to extrude the slurry from the discharging port (II) when restored from deformation. The material conveying transition mechanism (21) is configured to be arranged between the pumping device (2) and a spray gun to receive the slurry output every time in a pulsed manner by the pumping device (2), convert mechanical energy generated by pumped slurry pressure into elastic potential energy for storage, and gradually release the elastic potential energy to continuously and stably output the slurry, thereby achieving both spraying continuity and relatively large output flow, increasing a slurry spraying velocity of the spray gun, and improving the operating efficiency.
