[0001] The invention relates to the technical field of concrete testing, in particular to a proportioning device for testing a high-cracking-resistant concrete base. Background Art

[0002] High crack-resistant concrete base is a concrete material layer with excellent crack resistance, which is widely used in key parts of building structures such as floors, floors, and walls. It optimizes the ratio of raw materials such as cement, aggregates, and additives, and combines advanced concrete preparation and construction technology to significantly reduce the risk of cracks when the concrete base is subjected to various external forces and environmental changes, thereby improving the overall durability and safety of the structure. The use of high crack-resistant concrete base is of great significance for improving building quality and extending the service life of buildings.

[0003] A proportioning device is required in the production process of high crack-resistant concrete. Although the existing technology has met the user's needs to a certain extent, there are still certain defects in the use process. The specific problems are as follows: The existing concrete proportioning device is not convenient for cleaning the inner wall of the mixing drum after use, which will cause concrete material to remain on the inner wall of the mixing drum. These residues will not only affect the accuracy and reliability of the next proportioning test, but may also solidify due to long-term accumulation, increasing the difficulty and cost of cleaning, and even causing corrosion and damage to the mixing drum, shortening the service life of the equipment.

[0004] In order to solve the above problems, we made improvements and proposed a mixing device for high crack-resistant concrete base test. Summary of the invention

[0007] Preferably, a collection box is clamped to the top of the outer side of the batching cylinder. Cleaning brushes are fixedly connected to the bottoms of the left and right sides of the stirring rod. The outer sides of the cleaning brushes are in contact with the bottom of the outer side of the inner wall of the batching cylinder.

During the rotation of the screw rod, the screw sleeve is driven to move upward by the action of the thread. The screw sleeve drives the cylinder cover to move upward through the movable plate and the connecting rod. The cylinder cover drives the scraping plate to move upward through the stirring rod. The slurry adhered to the inner wall of the batching cylinder is scraped upward by the scraping plate, effectively removing the residual concrete, preventing the hardening of the concrete from increasing the cleaning difficulty and damaging the equipment, thereby maintaining the cleanliness and working efficiency of the equipment, ensuring the accuracy and reliability of the next proportioning test, and at the same time extending the service life of the equipment and reducing the maintenance cost.

[0017] Through the above technical solution, the output end of the servo motor 14 drives the screw rod 15 to rotate. During the rotation of the screw rod 15, the nut sleeve 16 is driven to move upward by the action of the thread. The nut sleeve 16 drives the cylinder cover 3 to move upward through the movable plate 24 and the connecting rod 9. The cylinder cover 3 drives the scraping plate 22 to move upward through the stirring rod 21. The slurry adhered to the inner wall of the batching cylinder 2 is scraped upward by the scraping plate 22, effectively removing the residual concrete, preventing the hardening of the concrete from increasing the cleaning difficulty and damaging the equipment, thereby maintaining the cleanliness and working efficiency of the equipment, ensuring the accuracy and reliability of the next proportioning test, and at the same time extending the service life of the equipment and reducing the maintenance cost.

[0018] Specifically, a liquid storage tank 7 is fixedly connected to the top of the adjustment box 6. On the right side of the inner cavity of the liquid storage tank 7, a water pump 13 is fixedly connected. The output end of the water pump 13 is communicated with a corrugated pipe 10.
