Description

Technical Field

[0001] This utility model relates to the field of grouting machine technology, and in particular to a grouting machine with controllable grouting volume. Background Technology

[0002] Grouting machines are key equipment used in construction, geological engineering and other fields to transport fluid materials such as mortar and cement slurry. They are widely used in foundation reinforcement, crack repair, tunnel lining and other operations. Their core function is to stably and quantitatively deliver grout to the target area, which directly affects the quality and efficiency of engineering construction.

[0003] Current grouting machines on the market still have significant shortcomings in practical applications: Firstly, the grout often contains large particles such as sand, gravel, and lumps, which can easily clog the grout delivery pipeline, interrupting the grouting operation and requiring a significant amount of time to disassemble and clean the pipeline, severely impacting the construction progress. Secondly, existing equipment often lacks convenient filter cleaning structures; even if some equipment has filter components, cleaning requires stopping the machine and disassembling multiple parts, making the operation cumbersome and maintenance costly. Furthermore, the grouting volume control of traditional grouting machines largely relies on manual adjustment, resulting in low precision and difficulty in... To adapt to the varying grouting volume requirements of different projects, there is an urgent need to develop a grouting machine that allows for flexible control of grouting volume through a combination of a solenoid valve and a flow control valve. This machine features a filter in the grout delivery pipe that can filter large particles of impurities, and the use of a water storage tank, flushing pipe, slag discharge port, and waste discharge hole allows for easy cleaning of clogged impurities on the filter. The machine combines precise and controllable grouting, ease of use, and convenient maintenance, thereby improving the efficiency and quality of grouting operations. This would overcome the shortcomings of current practical applications and meet current needs. Utility Model Content
