Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a concrete delivery pump hopper. Background Art

[0002] Concrete is one of the most important civil engineering materials in contemporary times. It is an artificial stone made of cementitious materials, granular aggregates, water, and admixtures and additives added in a certain proportion, which are evenly mixed, compacted into a dense shape, and cured and hardened. Concrete pump, also known as concrete pump, is a machine that uses pressure to continuously transport concrete along a pipeline. It is mainly used in house construction, bridge and tunnel construction. With the development of urban construction, concrete pumps often require hoppers to be used in conjunction with them when working.

[0003] However, the prior art still has the following problems:

[0004] First, the discharge port of the concrete delivery pump hopper in the prior art is mostly unable to control the discharge speed. When a large amount of concrete needs to be discharged, the device discharges the concrete at a slow speed, which may result in failure to complete the work within the specified time of the construction period, thus reducing the working efficiency of the device;

[0005] Secondly, most of the existing concrete delivery pumps have a stirring assembly in the hopper. When the hopper is not used for a short period of time, a large amount of concrete is accumulated in the hopper, and the concrete may solidify. As a result, when the device is needed later, the solidified concrete in the hopper must be cleaned before the device can be used, which reduces the versatility of the device.

[0006] In view of the above problems, the inventor proposes a concrete pump hopper for solving the above problems. Utility Model Content
