Description

Technical Field

[0001] The utility model relates to a concrete pumping hopper, which is mainly suitable for commercial concrete pumping construction during construction site, and is mainly used for splash protection of the pumping hopper during construction and concrete residue collection of the pumping hopper after the construction is completed. Background Art

[0002] The development process of concrete pumps is from piston type to extrusion type and then to piston type, from mechanical type to hydraulic type, from fixed type to towed type and then to vehicle-mounted type. At present, the development of concrete pump trucks continues to move towards environmental protection and energy saving, structural optimization, lightweight, automation, intelligence, and digitalization. In the direction of environmental protection and energy saving, the following problems need to be solved first:

[0003] (1) How to prevent leaves, paper scraps, plastic film and other debris from falling into the hopper during the pumping process, thus affecting the quality of concrete?

[0004] (2) During the feeding process of the hopper mixing mechanism, the concrete in the hopper is easy to splash, resulting in material waste;

[0005] (3) After completion, there is often concrete residue on the inner wall of the hopper. If it is cleaned directly through the discharge port, it will cause a lot of material waste.

[0006] In view of the above problems, it is urgent to invent a simple and effective concrete pumping hopper to reduce the impact of air debris falling into the hopper on quality, collect concrete residues for reuse, and achieve green environmental protection. Utility Model Content

By opening the discharge door plate, the concrete residue in the hopper can be cleaned and collected by graded filtration through a multi-stage barrel consisting of a primary barrel, a secondary barrel, a tertiary barrel and a quaternary barrel.

[0013] Furthermore, the screen is welded by steel bars into a grid structure, which is placed on the top of the hopper, and a sliding groove is arranged in the strip steel plate.

[0014] Furthermore, the folding cover is a retractable and foldable iron plate, and a push-pull plate is provided at the end of the folding cover. The push-pull plate fixes the push-pull handle. The folding cover is embedded in the sliding groove in the strip steel plate. Under the push of the push-pull handle, the folding cover can be telescopically folded along the sliding groove to achieve covering of the screen.

[0015] Furthermore, the first-level barrel, the second-level barrel, the third-level barrel and the fourth-level barrel are all connected to the bracket through a fixed cross bar. A filter screen is set under the first-level barrel, the second-level barrel and the third-level barrel. A discharge barrel pipe is set at the lower right corner of the upper part of the filter screen. A push-pull valve is set at the connection between the discharge barrel and the barrel to control the size of the collected material discharge.
