The scraper 1406 and the center line of the cement hopper 2 are on the same vertical line. The scraper 1406 matches the inner wall of the cement hopper 2. The motor 1402 is located inside the protective cover 20. The advantage is that during construction, when the workers start the motor 1402, the output shaft of the motor 1402 rotates and drives the scraper 1406 to rotate, which can scrape off the cement adhering to the inner wall of the cement hopper 2, avoiding waste, and also preventing the cement adhering to the inner wall of the cement hopper 2 from solidifying and becoming difficult to clean, making it highly practical.

[0038] Specifically, the insert 1407 and the slot 1404 are installed by plugging in. The bolt 1409 extends through the first threaded hole 1405 to the inside of the second threaded hole 1408. The first threaded hole 1405 and the second threaded hole 1408 have the same diameter. The advantage is that the operator can quickly install the scraper 1406 by inserting the insert 1407 into the slot 1404 and then extending the bolt 1409 through the first threaded hole 1405 to the second threaded hole 1408. After long-term use, it is easy to clean or replace, making it highly practical.

[0039] Specifically, the cement hopper 2, at the end furthest from the construction platform 1, has an installation groove 15 and a limiting groove 16. A filter screen 17 is installed at this end, with a limiting groove 18 along its outer edge. A limiting rod 19, compatible with the limiting grooves 16 and 18, is inserted into the end of the cement hopper 2 furthest from the construction platform 1. The filter screen 17 is fitted into the installation groove 15, and the limiting rod 19 extends through the limiting groove 16 into the limiting groove 18. The advantage is that workers can quickly install the filter screen 17 by inserting it into the installation groove 15 and then extending the limiting rod 19 through the limiting groove 16 into the limiting groove 18. After prolonged use, it is easy to clean or replace. The design of the filter screen 17 prevents larger sand and gravel from falling into the grouting tank 3, affecting the grouting quality, making it highly practical.

[0040] Working principle: During installation, the worker rotates the protective baffle 5 until it abuts against the construction platform 1, and then slides the limiting block 7 into the limiting groove 4, which quickly limits the protective baffle 5. The design of the protective baffle 5 prevents debris from falling into the grouting tank 3, making it highly practical. Next, the worker inserts the guide block 9 into the guide groove 11, and then rotates the guide tube 8 until the guide block 9 is completely submerged in the guide groove 11, achieving rapid positioning of the guide tube 8. After quickly positioning the guide tube 8, the worker inserts the limiting rod 13 through the through hole 12 and the through hole 10, achieving rapid positioning of the guide tube 8. This facilitates quick assembly and disassembly during use, making it highly practical. Finally, the worker inserts the insert block 1407 into the slot 1404, and then inserts the bolt 1409 through the threaded hole 1405 to the threaded hole 1408. The internal structure allows for quick installation of the scraper 1406, facilitating cleaning or replacement after prolonged use, making it highly practical. The worker then inserts the filter screen 17 into the installation slot 15, and then extends the limiting rod 19 through the limiting slot 16 to the limiting slot 18, enabling quick installation of the filter screen 17. This also facilitates cleaning or replacement after prolonged use. During use, the worker first connects the external power supply. During construction, the worker starts the motor 1402, causing the output shaft of the motor 1402 to rotate, which in turn drives the scraper 1406 to rotate, scraping off the cement adhering to the inner wall of the cement hopper 2, preventing waste and avoiding the cement from hardening and becoming difficult to clean. The filter screen 17's design also prevents larger sand and gravel from falling into the grouting tank 3, affecting the grouting quality, further enhancing its practicality.
