Feeding system for building contour forming

Abstract

A feeding system for building contour forming comprises a moving supporting platform, an intermediate bunker and a three-dimensional building printing spraying head arranged on the moving supporting platform. The intermediate bunker is arranged on the moving supporting platform and is connected with the three-dimensional building printing spraying head through a feeding pipeline; the intermediate bunker can connect with a traditional pump truck for feeding; and stirred concrete raw materials on the ground are conveyed to the intermediate bunker through a pump machine, and then the materials are supplied to the three-dimensional building printing spraying head through the intermediate bunker. The feeding pipeline just needs to be arranged between the intermediate bunker and the three-dimensional building printing spraying head, the length of the feeding pipeline can be reduced, and the probability of feeding pipeline blocking is reduced. When raw materials with different granularity are conveyed, due to buffering through the intermediate bunker, the raw materials can be selected in wider ranges to be used, and the efficiency of material supplying to the three-dimensional building printing spraying head can be improved.

Description

technical field [0001] The invention relates to the field of building equipment, in particular to equipment for building contour forming, in particular to a material supply system for building contour forming. Background technique [0002] The feeding system of the existing contour forming technology is connected with the 3D building printing nozzle through the screw type, hydraulic concrete and mortar pump truck, and the pipe (mainly made of rubber or metal) and the 3D building printing nozzle. The size of the feed pipe diameter of the forming equipment determines that the machine can only eat raw materials with appropriate thickness, which greatly increases the supply chain cost of raw materials. If the raw material particle size is too large, it is easy to damage the stator, rotor or hydraulic mechanism of the pump. , which increases the maintenance cost, and it is very easy to block the feeding pipe, which reduces the feeding efficiency; if the raw material is too fine, ...

Problems solved by technology

[0002] The feeding system of the existing contour forming technology is connected with the 3D building printing nozzle through the screw type, hydraulic concrete and mortar pump truck, and the pipe (mainly made of rubber or metal) and the 3D building printing nozzle. The size of the feed pipe diameter of the forming equipment determines that the machine can only eat raw materials with appropriate thickness, which greatly increases the supply chain cost of raw materials. If the raw material particle size is too large, it is easy to damage the stator, rotor or hydraulic mechanism of the pump. , which increases the maintenance cost, and it is very easy to block the feeding pipe, which reduces the feeding efficiency; if the raw material is too fine, it is not conducive to forming the raw material immediately after printing, because if the raw material particle size is too small, when the thrust of the machine is constant, the output The speed of the nozzle will increase, it is extremely difficult to control the plasticity of the raw material, and with the expansion of the working range, the feeding pipe will become longer and longer. In particular, in 3D architectural printing equipment, the Z-axis often needs to have a certain working height. The material is supplied from a low-level position such as the ground to a platform with a considerable height, which requires considerable pressure; the higher the floor, the greater the pressure, which increases the difficulty of material supply and reduces the operating efficiency. When the feed pipe is long and the feed device delivers the material directly to the nozzle, it will be difficult to achieve a stable feed, and it will also increase the chance of clogging the feed pipe
