A high-pressure concrete stamping feeding device

Abstract

The invention discloses a high-pressure concrete punching and feeding device, which includes a machine base, a punching device, a feeding device, a feeding box and a pre-stirring device. The punching device includes a punching box, a mixing tank, a lubricating box, an oil pressure box, a first A punching tube, a second punching tube, a punching rod, a punching piston and a punching disc, the pre-mixing device includes a hopper, a stirring motor, a stirring shaft and a rotary knife, and the feeding device includes a reciprocating motor, a telescopic push rod, and a feeding pipeline and plugging, the stamping rod is provided with a stamping piston at one end close to the oil pressure tank, the other end of the stamping rod is connected to the stamping plate located inside the mixing tank, and the feeding pipe is connected to the bottom of the supply hopper The end of the feeding pipeline away from the reciprocating motor communicates with the middle of the mixing tank, and the inner wall of the mixing tank is provided with pointed thorns. The invention improves the bearing capacity of loose soil by stamping the concrete and effectively mixing the concrete while eliminating air bubbles in the concrete.

Description

technical field [0001] The invention relates to the technical field of high-pressure concrete pressing, in particular to a high-pressure concrete stamping feeding device. Background technique [0002] Traditionally, some old buildings are reinforced later or some loose soils are reinforced by using concrete pumps to press concrete into the soil for reinforcement, but the existing concrete pumps are prone to clogging and lack of lubrication in the long-term working state. Oil lubrication leads to insufficient pressure. It is difficult for the concrete pump to eliminate the agglomeration and air bubbles in the concrete during normal work, and it is easy to cause secondary depression or collapse after construction, which is very unsafe. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0004] The object of the present invention is to provide a high-pressure concrete stamping feeding device to...
