Concrete conveying pump

Abstract

The invention relates to a concrete conveying pump. The concrete conveying pump comprises a base, a support block, a controller, a conveying mechanism and a feeding mechanism, the feeding mechanism comprises a hopper, a cover plate, a power assembly, a rotating shaft, a serrated block, a screening net and two stirring plates, the conveying mechanism comprises a driving assembly, a conveying pipe, a connecting pipe and two conveying assemblies, and the conveying assemblies comprise discharging pipes, feeding pipes, sealing plugs and driving rods. According to the concrete conveying pump, large pieces of aggregate and clumps in concrete can be ground into fine and small particles through the feeding mechanism, plugging occurring in the conveying process is avoided, smooth circulation is ensured, not only that, the two feeding pipes provide the concrete for the connecting pipe through the connecting pipe by utilizing the conveying mechanism, so that the concrete is continuously conveyed out from the conveying pipe, the concrete conveying efficiency and the conveying stability are improved, and thus the practicality of the concrete conveying pump is improved.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to a concrete conveying pump. Background technique [0002] Concrete delivery pump, also known as concrete pump, is composed of a pump body and a delivery pipe. It is a machine that uses pressure to continuously transport concrete along the pipeline. It is mainly used in house construction, bridge and tunnel construction. It is mainly divided into gate valve concrete delivery pump and S-valve concrete delivery pump. The other one is to install the pump body on the chassis of the car, and then equip it with a telescopic or inflection boom to form a pump truck. [0003] However, during the operation of the existing concrete pumps, larger aggregates or agglomerates are often blocked inside the feed pipeline, resulting in slow feed, and in severe cases, pipeline blockage and equipment failure.

[0003] However, during the operation of the existing concrete pumps, larger aggregates or agglomerates are often blocked inside the feed pipeline, resulting in slow feed, and in severe cases, pipeline blockage and equipment failure. Not only that, the existing At the same time, the concrete delivery pump realizes the delivery of concrete by moving the piston back and forth. When delivering, the piston first sucks the concrete into the delivery pipeline through the hopper, and then the piston moves in the opposite direction to push the concrete out of the delivery pipeline. Therefore, the existing concrete is All of them adopt the way of intermittent conveying, which not only reduces the conveying efficiency, but also affects the precise control of the conveying volume due to the discontinuous conveying, which leads to the reduction of the practicability of the existing concrete conveying pumps.
