The lower part accessory is a material receiving extension end and mainly plays a role in protecting the middle accessory. The tool effectively solves the problem that the concrete of the top plate has color difference after later form removal due to the fact that the pump pipe is not sealed and the excess concrete falls to the top plate after the wall is poured on the construction site; thereby effectively improving the impression quality of the concrete, improving the construction period and reducing the procedures of polishing and repairing the concrete. And the device can complete the pipe connection quickly in a short time before pouring, the accessory is convenient to manufacture, and the construction problem is effectively solved. Meanwhile, the device has the advantages of simple structure, convenient material taking, lower cost, repeated turnover use, wide application range and repeated use.

Detailed Description
The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings:
the automatic closer for the discharge hole of the concrete pump pipe shown in figure 1 is composed of three parts, wherein the three parts are hollow structures, and specifically comprise an upper part fitting, a middle part fitting and a lower part fitting, and the three parts are connected through bolts.
The upper part fitting is of a three-stage step cylinder structure with diameters gradually increased from top to bottom, and is formed by welding a small-diameter steel pipe, a large-diameter steel pipe and a perforated steel plate, and a middle cavity through hole is used for connecting the end part of a pump pipe; the upper part accessory is divided into a left part and a right part which are symmetrical in structure, one side of the opening butt joint surface of the left half part 3 and the right half part 2 is hinged through a hinge, and the other side of the opening butt joint surface is movably connected through a buckle lock 1, so that the opening and closing of the upper part accessory are facilitated and the pump pipe is connected with the pump pipe. The hinge and the latch are standard and commercially available, and the basic structure of the latch is shown in fig. 3a, 3b and 3 c.
The middle part is a check valve 4, the structure of the check valve is shown in fig. 4, and the check valve comprises an annular valve body plate 45, a pressure plate 41 and a spring rod 44, an I-shaped fixing seat 43 is transversely arranged on the inner side of the annular valve body plate 45, the spring rod 44 is rotatably installed on a cross rod of the fixing seat 43 in a resetting manner, the pressure plate 41 is arranged above the spring rod 44 and hinged with the annular valve body plate 45, and the resetting elasticity of the spring rod 44 faces the pressure plate 41, so that the pressure plate 41 is in a radial plane horizontal state in a natural state. The level of the pressing plate is controlled by the elasticity of the spring rod, concrete excess materials are prevented from being exposed, only when the concrete needs to be poured on a construction site, the elasticity of the spring rod is overcome under the action of large concrete external force, the pressing plate is opened, and the concrete rushes out of the pump pipe, so that pouring is realized.
The principle of the check valve is that under the action of fluid pressure flowing in one direction, a valve clack is opened, and a valve plate is closed when the fluid force is small. Through repeated tests, the thickness of the pressure plate 41 is finally determined to be 3mm, the thickness of the annular valve body plate 45 is finally determined to be 20mm, and the diameter of the spring is finally determined to be 6 mm.
The structure of the lower part fitting is a two-step cylinder structure with a large upper part and a small lower part, and is formed by welding an open pore steel plate and a steel pipe, as shown in fig. 5.
The perforated steel plates of the upper part fittings and the lower part fittings are made of 5mm steel plates, the diameter of a bolt hole is 14mm, the diameter of a bolt is 12mm, and the wall thickness of the steel pipe adopted by the upper part fittings and the lower part fittings of the steel pipe is 5 mm.
In the earlier stage of concrete pouring, after a concrete automobile pump or a distributing machine is in place, upper parts, middle parts (check valves) and lower parts are assembled through bolts and connected with an original concrete pump pipe, and then the assembly of the parts can be completed. When the concrete is poured, the concrete is ejected out of the pump pipe by the steam pressure of the concrete steam pump, and the middle fitting, namely the check valve, is ejected out of the pump pipe under the action of a larger external force of the concrete, so that the pouring is finished. When the pressure of the automobile pump is closed, the check valve acts, and the outlet is automatically closed through the spring pressure rod. When the bolt is disassembled, the bolt between the upper part accessory lock and the accessory is unscrewed.
