Problems solved by technology

The pipes assembled by pre-installed pipes are low in efficiency and easy to leak, and have been gradually eliminated. Most of the underdrain pipes are poured with concrete pipe continuous forming machines. Although the current underdrain concrete pipe continuous forming machines can achieve continuous However, it must be molded in two parts, the lower part is poured first, and then the upper part is poured. The connection between the upper and lower parts is poor, and leakage is easy to occur, and the efficiency is low and the cost is high.

Embodiment Construction

[0025] Such as figure 1 , 2 As shown, it includes a frame 21, an inner mold 1, an outer mold 2, a compression piston 3, an oval ring plate 5, a rubber pad 4, a feed port 6, a feed channel 7, a feed hopper 8, a crawler 9, a slide Ram 10, differential inner push plate 20, front end plate 11, rear end plate 12, push plate 13, guide rod 14, gate push rod 16, piston push rod 17, screw rod 15, guide roller 18 and slide plate 19.

[0026] The front end of the frame 21 is equipped with a pipeline compression molding mechanism, which includes an inner mold 1, an outer mold 2, and a compression piston 3. Both the inner mold 1 and the outer mold 2 are bent into arcs by two steel plates and then connected and fixed into an ellipse. (see image 3 ), the inside and outside of the inner and outer molds are arranged together to form an elliptical ring cavity. The end of the mold cavity is a discharge port, and an elliptical annular compression piston 3 is arranged in the cavity to squeeze ...

Abstract

The invention relates to an agricultural integral continuous extrusion forming machine for an elliptic concrete pipe. The forming machine comprises a frame, a pipe compression forming mechanism arranged at the front end of the frame, a feeding mechanism arranged on the pipe forming mechanism, a power propulsion mechanism arranged on the frame, and a guiding sliding mechanism. During construction,the forming machine is placed in a pre-dug groove, concrete enters an elliptic annular die cavity of the pipe compression forming mechanism through a feeding hole and a feeding passage of the feedingmechanism, and an elliptic annular compression piston moves forwards under the action of the power propulsion mechanism to extrude and compact the concrete; and when the compression piston cannot further propel the concrete in the cavity, the forming machine is subjected to the reacting force of the concrete and continuously moves forwards under the guide of the guiding sliding mechanism so as torealize integral continuous casting of the elliptic annular pipe. The caliber of the cast-in-place continuous extrusion elliptic concrete pipe reaches 600 to 2,000 millimeters; and the forming machine has the advantages of one-time casting forming, leakage prevention and high casting efficiency, and reduces the production cost.

Description

technical field [0001] The invention relates to an integral continuous extrusion molding machine for concrete pipes, which is particularly suitable for integral continuous pouring of farmland irrigation and drainage culvert pipes or urban drainage pipes. Background technique [0002] Existing farmland irrigation and drainage culverts are composed of joints of prefabricated concrete pipes that are assembled with a binder, or are directly poured and formed by a concrete pipe forming machine. The pipes assembled by pre-installed pipes are low in efficiency and easy to leak, and have been gradually eliminated. Most of the underdrain pipes are poured with concrete pipe continuous forming machines. The current underdrain concrete pipe continuous forming machines can achieve continuous However, it must be molded in two parts, the lower half is poured first, and then the upper half is poured. The joints of the upper and lower halves are poorly bonded, prone to leakage, low in effici...
