[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: a concrete additive reactor, including a kettle body 1, a concrete adding port 11 is fixedly connected to the left side of the top of the kettle body 1, a support leg 12 is fixedly connected to the bottom surface of the kettle body 1, a cross connecting frame 2 is fixedly connected to the bottom of the inner part of the kettle body 1, a transmission shaft 3 is rotatably connected to the top of the cross connecting frame 2 through a bearing, a first motor 4 is fixedly connected to the top end of the transmission shaft 3, a motor base 5 is fixedly connected to the top of the first motor 4, a stirring rod 6 and a scraper 7 are fixedly connected to the surface of the transmission shaft 3, an adding mechanism 8 is fixedly connected to the right side of the top of the kettle body 1, and a discharging mechanism 9 is fixedly connected to the bottom of the kettle body 1;
[0022] The top of the cross connecting frame 2 is designed as an inclined surface, the top end of the transmission shaft 3 is fixedly connected to the bottom end of the first motor 4 through a flange plate, the bottom of the motor base 5 is fixedly connected to the middle of the top of the kettle body 1, the number of the stirring rods 6 is sixteen, and the sixteen stirring rods 6 are fixedly connected to the surface of the transmission shaft 3 in groups of eight at equal circumferential intervals. The number of the scrapers 7 is four, and the four scrapers 7 are fixedly connected to the surface of the transmission shaft 3 at equal circumferential intervals. The outer side of the scraper 7 is attached to the inner wall of the kettle body 1.
[0023] Further, the adding mechanism 8 includes a storage barrel 811, which is fixedly connected to the right side of the top of the kettle body 1, a feeding port 812 is fixedly connected to the bottom of the storage barrel 811, a adding port 813 is fixedly connected to the right side of the top of the storage barrel 811, a second motor 814 is fixedly connected to the top of the storage barrel 811, a rotating shaft 815 is fixedly connected to the bottom end of the second motor 814, and a circular plate 816 is fixedly connected to the bottom end of the rotating shaft 815;
[0024] The second motor 814 is fixedly connected to the middle of the top of the storage barrel 811 through a motor plate, and the bottom of the second motor 814 is rotatably connected to the top of the storage barrel 811 through a bearing. A trapezoidal opening is opened at the bottom of the circular plate 816, and the bottom of the circular plate 816 is slidably connected to the bottom of the storage barrel 811.
[0025] It should be noted that when adding additives, the additives are poured into the storage barrel 811 from the addition port 813. When discharging, the second motor 814 at the top of the storage barrel 811 is started. Under the transmission of the second motor 814, the rotating shaft 815 fixedly connected at the bottom is driven to rotate, thereby driving the circular plate 816 to rotate at the bottom of the storage barrel 811. When the trapezoidal opening on the surface of the circular plate 816 coincides with the discharging port 812, the additives inside the storage barrel 811 fall into the kettle body 1 and are mixed with the concrete. When the trapezoidal opening on the surface of the circular plate 816 continues to rotate, the top of the discharging port 812 is blocked, and the additives cannot fall. Under the operation of the second motor 814, the circular plate 816 is continuously overlapped with and blocked with the top of the discharging port 812, and then the addition inside the storage barrel 811 can be realized. Discharge into the kettle body 1 can be achieved step by step, avoiding the problem that some additives are difficult to fully mix after adding the additives at one time, thereby improving the mixing degree of concrete and additives.
[0026] Further, the discharge mechanism 9 includes an arc-shaped base 911, which is fixedly connected to the bottom of the kettle body 1, and an L-shaped discharge pipe 912 is fixedly connected to the bottom of the arc-shaped base 911, and the left end of the L-shaped discharge pipe 912 is rotatably connected to a third motor 913, and a fixed seat 914 is fixedly connected to the left side of the third motor 913, and a discharge shaft 915 is fixedly connected to the right end of the third motor 913;
[0027] The arc base 911 is designed with a forty-five-degree slope. The right end of the fixed seat 914 is fixedly connected to the left side of the L-shaped discharge pipe 912. The surface of the discharge shaft 915 is provided with a threaded coil, and the threaded coil on the surface of the discharge shaft 915 fits the inner wall of the L-shaped discharge pipe 912.
[0028] It should be noted that when discharging concrete, by starting the third motor 913, under the fixation of the fixed seat 914, the third motor 913 drives the discharge shaft 915 fixedly connected at the right end to rotate. When the concrete falls on the surface of the discharge shaft 915, it can be continuously discharged from the right end of the L-shaped discharge pipe 912 under the transportation of the discharge shaft 915, so as to avoid the problem that the concrete itself is too viscous and blocks the L-shaped discharge pipe 912, making it difficult to discharge. The forty-five-degree inclined surface design of the arc-shaped base 911 also facilitates the complete discharge of the concrete remaining at the bottom of the kettle body 1 to prevent the internal residue from drying and adhering to the inside of the kettle body 1.
[0029] Working principle: When using the device, concrete is added into the kettle body 1 from the concrete adding port 11, and the first motor 4 on the top of the kettle body 1 is started. Under the fixation of the motor base 5, the first motor 4 drives the transmission shaft 3 to rotate inside the kettle body 1, and then the stirring rod 6 and the scraper 7 fixed on the surface of the transmission shaft 3 rotate, driving the concrete to turn inside the kettle body 1. At the same time, the scraper 7 can scrape off the concrete attached to the inner wall of the kettle body 1, so that it can be fully mixed with the additive, and then the additive is removed from the adding port 11. The material is poured into the storage barrel 811 through the addition port 813. When the material is discharged, the second motor 814 at the top of the storage barrel 811 is started. Under the drive of the second motor 814, the rotating shaft 815 fixed at the bottom is driven to rotate, thereby driving the circular plate 816 to rotate at the bottom of the storage barrel 811. When the trapezoidal opening on the surface of the circular plate 816 coincides with the discharge port 812, the additive inside the storage barrel 811 falls into the kettle body 1 and is mixed with the concrete under the stirring of the stirring rod 6. When the trapezoidal opening on the surface of the circular plate 816 continues to overlap with the discharge port 812, the additive inside the storage barrel 811 falls into the kettle body 1 and is mixed with the concrete under the stirring of the stirring rod 6. After the continuous rotation, the top of the discharge port 812 is blocked, and the additive cannot fall. Under the operation of the second motor 814, the circular plate 816 is constantly overlapped with and blocked with the top of the discharge port 812, so that the material added inside the storage barrel 811 can be gradually discharged into the kettle body 1, avoiding the problem that some additives are difficult to fully mix after adding the additives at one time, thereby improving the mixing degree of concrete and additives. When the concrete and additives are fully mixed, by starting the third motor 913, under the fixation of the fixed seat 914, the third motor 913 drives the discharge shaft 915 fixedly connected at the right end to rotate. When the concrete falls on the surface of the discharge shaft 915, it can be continuously discharged from the right end of the L-shaped discharge pipe 912 under the transportation of the discharge shaft 915, thereby avoiding the problem that the concrete itself is too viscous and blocks the L-shaped discharge pipe 912, making it difficult to discharge. The forty-five-degree inclined surface design of the arc base 911 also facilitates the complete discharge of the concrete remaining at the bottom of the kettle body 1, preventing the internal residue from drying and adhering to the inside of the kettle body 1.
[0030] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present utility model, rather than limiting the protection scope of the present utility model. Any simple modification or equivalent replacement made by those of ordinary skill in the art to the technical solution of the present utility model shall not depart from the essence and scope of the technical solution of the present utility model.
