Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mortar conveying, and more specifically to a cement mortar conveying mechanism. Background Art
[0002] Cement mortar is a commonly used building material, which is made by mixing cement, fine aggregate (such as sand) and an appropriate amount of concrete additives in a certain proportion. It has the characteristics of strong adhesion and high compressive strength after hardening. Cement mortar is widely used in construction projects to fill gaps in walls, floors, ceilings, etc., repair damaged parts, fix components, and make brickwork and stone pasting. Cement mortar is not only simple and easy to use, but also economical and affordable, and the construction process is relatively fast. In the field of construction, cement mortar plays an important role, providing reliable support and protection for various building structures.
[0003] The cement mortar conveying mechanism is a device used to transport cement mortar from the mixing plant to the construction site. It consists of a conveying pipeline, a conveying pump, and a control system. First, the cement mortar is loaded into the mixing tank and loaded into the conveying pipeline through a screw conveyor or a hoist. Next, the conveying pump generates high pressure to push the cement mortar to flow in the pipeline while maintaining a stable flow rate and pressure. During the conveying process, the conveying speed and the operating status of the pump can be adjusted by the control system. Finally, the cement mortar arrives at the construction site and can be directly supplied to the required area through the pipeline.
[0004] When the existing cement mortar conveying mechanism is discharging cement mortar, the cement mortar may contain impurities such as stones, which may cause blockage of the metal mesh. At the same time, the push plate may collide with the metal mesh when scraping, resulting in a reduction in its service life. The cement mortar may solidify during the conveying process, resulting in a decrease in its conveying efficiency and affecting the use of the equipment. For this reason, we propose a cement mortar conveying mechanism. Utility Model Content
