Description

Technical Field

[0001] This utility model relates to the field of concrete mixing equipment technology, and in particular to a water conveying mechanism for a concrete mixer. Background Technology

[0002] The production process of reinforced concrete drainage pipes requires a concrete mixer to prepare concrete. The water delivery mechanism is the core component of the concrete mixer. The water delivery mechanism mainly consists of a water tank, a water pump, water pipes, and a water meter. The water pump is the power equipment of the water supply system, which transports water from the water tank to the mixing drum through the water pipes. The water meter is used to accurately measure the water consumption to ensure that the water-cement ratio of the concrete meets the design requirements.

[0003] In existing concrete mixer water supply mechanisms, the water inlet pipe is usually manually inserted into the feed inlet of the concrete mixer. Due to the relatively large structure of the concrete mixer, the insertion process is troublesome. In addition, the end of the water inlet pipe is usually equipped with a filter screen, and large particles in the water and external sand and gravel can easily clog the filter screen, requiring regular maintenance and cleaning. However, the filter screen is fixed in its installation structure and is not easy to disassemble, which increases the workload of maintenance personnel. Utility Model Content
