Concrete continuous and uniform blanking device for pipe pile production

Abstract

The invention relates to a concrete continuous and uniform blanking device for pipe pile production, which comprises a bin. A discharge port positioned at the bottom of the bin is communicated with a steel die inlet; the top of the bin is communicated with a discharge port of a concrete mixer; a driving shaft and a driven shaft are arranged on the bin; a first transmission gear is arranged on the driving shaft; a second transmission gear is arranged on the driven shaft; the driving shaft transfers power to the driven shaft by the meshing of the first transmission gear and the second transmission gear; stirring blades are fixedly arranged on both the driving shaft and the driven shaft; when the driving shaft and the driven shaft rotate, the stirring blades can carry out secondary stirring on concrete discharged from the concrete mixer. The concrete continuous and uniform blanking device implements secondary stirring on the concrete jetted from the mixer above the concrete continuous and uniform blanking device, has a buffering effect on a blanking speed, and controls a discharging speed by controlling the rotating speed of the blades in the bin.

Description

technical field [0001] The invention relates to a device capable of continuously and uniformly distributing concrete into the pipe pile steel form in the pipe pile industry, and is mainly suitable for the pipe pile manufacturing industry in China with low degree of automation and extensive production. Background technique [0002] At the end of the 1960s, in order to meet the needs of the infrastructure construction of railway bridge projects, the pipe pile industry appeared in China. Nowadays, with the rapid development of reform and opening up and economic construction, the application of concrete pipe piles has expanded from the railway system to industrial and civil buildings, municipal administration, metallurgy, ports, highways and other fields. Especially in the Yangtze River Delta and Pearl River Delta regions, because the geological conditions are suitable for the use of pipe piles, the demand for concrete pipe piles has soared. Because of this high demand, the pipe...

Problems solved by technology

[0004]1. Due to the working characteristics of the mixers used in the pipe pile industry in China today, the concrete cannot be fully mixed evenly; 2. The process of concrete falling into the steel mold is intermittent 3. Because the output speed of the concrete mixer is not controlled, the concrete will splash out when it falls into the steel mold in many cases, causing a lot of waste, the working environment of the workers is very poor, and it also causes the lower Potential safety hazards for workers; 4. Concrete falls into the steel mold in the form of clumps, which is easy to form accumulations on the steel cage

[0005]However, in recent years, domestic research and design on continuous and uniform material distribution devices in the production of pipe pile industry is almost zero, the production process is still extensive, the production environment is poor, and there are big security risk
