Description
Technical Field
[0001] The utility model relates to the technical field of water-stabilized mixing equipment, in particular to a device for adding a recycled cement-stabilized crushed stone admixture. Background Art
[0002] Cement-stabilized crushed stone material uses graded crushed stone as aggregate, combined with a binder (such as cement) and a certain volume of mortar to fill the voids. This mixture, which primarily relies on the interlocking effect of the crushed stone, possesses a certain mechanical strength and density. The cement imparts high initial strength, which increases with age and forms a cohesive structure. Due to its high strength and stiffness, it is widely used in highway base construction. However, due to the brittle nature of cement-stabilized crushed stone bases, shrinkage cracks are prone to occur under the combined effects of temperature and humidity, traffic loads, and environmental stresses, posing a potential threat to the highway being constructed. By incorporating composite admixtures during construction, the morphological and activity effects of these materials within the mixture, combined with the micro-aggregate filling effect, complement each other to create a superimposed effect, improving the road performance of cement-stabilized crushed stone.
[0003] The admixture needs to be mixed evenly with water before being added to the cement-stabilized gravel mixing device. Currently, the dissolution and mixing of the admixture needs to be carried out in a separately set mixing tank. The admixture and water are not mixed evenly or due to temperature influences, solids of the admixture are likely to remain at the bottom of the tank. At the same time, the mixing tank is a closed device and the internal parts cannot be replaced. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a device for adding a recycled cement stabilized gravel admixture, so that the admixture and water can be fully mixed, and an insulation mechanism is provided to prevent solid residues of the admixture from remaining at the bottom of the pool. At the same time, the internal parts can be replaced, which can effectively solve the problems in the background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for adding an admixture to recycled cement-stabilized gravel, comprising a mixing tank, a motor protection frame and a mixing device;
[0006] The top of the mixing tank is connected to the cover plate by bolts, a stirring device is installed in the cover plate, a feed port is installed on the left side of the mixing tank, a water spray device is installed on the right side of the mixing tank, a liquid discharge device is installed at the bottom of the mixing tank, and a first mounting bracket is installed on the outside of the mixing tank;
[0007] Stirring device: includes a motor, a first mounting frame, a connecting shaft 1, a connecting shaft 2, a large gear, an upper cover plate, a gear ring, a lower cover plate, a rotating plate, a connecting plate, a stirring shaft, a small gear, a paddle stirring blade and a frame stirring blade. The motor protection frame is installed at the center of the upper surface of the upper cover plate. The motor is installed at the center of the motor protection frame. The output shaft of the motor is fixedly connected to the top of the first mounting frame. The bottom end of the first mounting frame is fixedly installed with a connecting shaft 1 and a connecting shaft 2. There are three connecting shafts 1 and 2 respectively, and the three connecting shafts 1 and 2 are interspersed. The three connecting shafts are equidistantly distributed on the circumference of the first mounting frame. One end of the three connecting shafts is rotatably connected to a pinion gear at a distance from the first mounting frame. A large gear is mounted on the lower end of the first mounting frame. A ring gear is meshed on the outer side of the small gear, and the small gear is meshed between the large gear and the ring gear. The end of the second connecting shaft away from the first mounting frame is fixedly connected to a rotating plate, and the bottom of the large gear is rotatably connected to the rotating plate through a support rod. The bottom of the small gear is fixedly connected to the stirring shaft. A frame stirring blade and a paddle stirring blade are mounted on the stirring shaft.

[0008] An armrest is installed on the cover plate.
[0009] The top of the mixing tank is connected to the cover by bolts and can be disassembled to replace the internal parts. The handrail can assist the crane to remove the cover. The center of the motor protection frame protects the motor from damage. After the motor is started, the first mounting frame begins to rotate, causing the pinion to rotate on the ring gear, and the rotating plate also begins to rotate. During the rotation of the pinion, the stirring shaft rotates, and the stirring shaft causes the frame stirring blades and the paddle stirring blades to rotate, so that the admixture and water can be fully integrated.
[0010] Furthermore, the bottom of the upper cover is fixedly connected to the ring gear, and a connecting plate is fixedly mounted on the outside of the upper cover. The bottom of the ring gear is fixedly connected to the lower cover. A rotating groove is provided in the middle of the lower cover, and the rotating plate rotates within the rotating groove. The upper and lower cover plates secure the ring gear and prevent external interference with the large and small gears. The connecting plate is where the top of the mixing tank connects to the cover plate. The rotating plate prevents water and solution in the mixing tank from affecting the large and small gears.
[0011] Furthermore, the water spray device includes a water inlet pipe, a second mounting bracket, and a ring-shaped faucet.

The water inlet pipe delivers water to the ring-shaped faucet, which delivers water to the interior of the mixing tank and also has the function of cleaning the interior of the mixing tank.
[0012] Furthermore, the drainage device includes a filter, a check valve, and a drain pipe. A drain hole is provided at the bottom of the mixing tank, and a filter is installed within the drain hole. The bottom of the drain hole is fixedly connected to the check valve, and the drain outlet of the check valve is connected to the drain pipe. When the admixture and water form a solvent, the filter filters the solvent, the check valve controls the outflow of the solvent, and the drain pipe sends the solvent to other locations.
[0013] Furthermore, the mixing tank also includes a heating layer, a wear-resistant layer inside the mixing tank, a heating layer at the lower middle end of the mixing tank, and a heat-insulating layer outside the mixing tank. The wear-resistant layer prevents the admixture from damaging the mixing tank, and the heating layer heats the interior of the mixing tank to accelerate the formation of a solvent between the admixture and water.
[0014] Furthermore, the bottom of the mixing tank is conical, the bottom of the frame-type stirring blade is at the same angle as the bottom of the mixing tank, and the sides of the frame-type stirring blade are arc-shaped. The conical bottom of the mixing tank facilitates the flow of solution from the bottom of the mixing tank and reduces residue. During rotation, the bottom and sides of the frame-type stirring blade are at a certain distance from the interior of the mixing tank, which facilitates the stirring of additives adhering to the inner wall of the mixing tank.
