Automatic feeding control device for concrete 3D printing tool end

Abstract

The invention relates to an automatic feeding control device for a concrete 3D printing tool end. The automatic feeding control device comprises a tubular shell, the tail portion of the interior of the shell is fixedly provided with an inner pipe, the front end of the inner pipe is sequentially provided with a conductive ring for opening a pump truck, a backing ring and a conductive ring for stopping the pump truck from front to back, and the rear end of the inner pipe is a spring seat and is provided with a cylindrical coil spring; and the front end of the cylindrical coil spring is providedwith a columnar button, the tail of the button is inserted into the inner pipe, a spring contact finger is arranged on the outer wall of the button, and the head of the button extends out of the headof the shell. According to the automatic feeding control device, a limit switch is adopted for controlling residual materials of a hopper, the switch is switched on when the residual materials are less than the design lower limit of the limit switch, and a mixer pumps the materials to the hopper. When the residual materials are more than the design upper limit of the limit switch, the switch is switched off, and the mixer stops pumping the materials to the hopper. The application of the limit switch increases the automation degree of a discharge device, and manpower is saved.

Description

technical field [0001] The invention relates to the technical field of concrete 3D construction, in particular to an automatic feeding control device for a concrete 3D printing tool end. Background technique [0002] With the development of traditional concrete construction, its limitations are gradually exposed. For complex special-shaped structures, traditional concrete pouring methods are difficult to do. Its high cost, low construction efficiency, and slow construction speed seriously restrict traditional concrete pouring in local areas. field development. Therefore, combined with the development of modern industry, combining concrete pouring and industrial robots, concrete 3D printing construction came into being. Its advantages lie in its high construction efficiency and strong degree of personalization, which transforms the traditional construction that mainly relies on human physical labor into mainly relying on human mental labor to achieve purposeful construction....
