Problems solved by technology
[0005] Aiming at the deficiencies of the prior art, the present invention provides a material conveying device for subway shield tunneling. The telescopic rod is driven by the cylinder, and the telescopic rod drives the first movable plate to reciprocate between the piston head and the baffle plate. Pressing and crushing, at the same time, the second movable plate stretches under the action of the torsion spring to push the surrounding bulk materials, thus solving the problem of blockage of bulk materials between the piston head and the baffle

The invention relates to the technical field of subway shield construction, particularly to a subway shield construction conveying device, which includes a first spiral feeding device, a settling vat,a second spiral feeding device, a breaking device and a stirring device, wherein a discharging barrel is connected with the bottom of the settling vat; a groove is connected between the two inner walls at the front and rear parts of the discharging barrel; two movable rods are arranged at the bottom of the groove; a piston head is connected with the top of each movable rod; an air cylinder is arranged between the two movable rods; a first separation room and a second separation room are arranged inside the piston heads; a first movable plate is arranged inside the first separation room; the two ends of the first movable plates are connected through a second movable plate via torsional springs; a telescopic rod is connected with the bottom of the first movable plate, and penetrates throughthe piston head and is connected with the air cylinder; the air cylinder can drive the telescopic rod to move vertically, so that the first movable plate and the second movable plate can be used forpushing large materials, and the problem that large materials are stacked at coarse outlets is effectively solved.
Description
technical field [0001] The invention relates to the technical field of subway shield tunnel construction, in particular to a transportation device for subway shield tunnel construction. Background technique [0002] Shield method is a comprehensive construction technology. The main content of the shield tunneling method construction is: first build a shaft or foundation pit at one end of a certain section of the tunnel for the shield to be installed in place. The shield starts from the reserved hole in the wall of the vertical shaft or foundation pit, and advances to the designed reserved hole of another vertical shaft or foundation pit along the design axis in the stratum. The shield is a circular steel cylinder structure that can support the formation pressure and can be pushed in the formation. Its diameter is slightly larger than the diameter of the tunnel lining. Various types of support and soil excavation devices are arranged in front of the steel cylinder. , the ja...
