[0019] Embodiment 1
[0020] Please refer to the attached Figure 1 This application provides an efficient concrete batching device, including a batching tank 1, a stirrer 2, a screw conveyor 3 and a storage tank 4. The upper end of the batching tank 1 is provided with a water inlet pipe 5, and the bottom is provided with a discharge pipe 6. The storage tank 4 stores concrete additives. The bottom of the storage tank 4 is connected to the feed inlet of the screw conveyor 3, and the discharge outlet of the screw conveyor 3 is connected to the batching tank 1. The stirrer 2 is arranged in the batching tank 1. The concrete additives are stored in the storage tank 4, and then the concrete additives are transported to the batching tank 1 through the screw conveyor 3. When batching, water is transported into the batching tank 1 through the water inlet pipe 5, and the stirrer 2 is started for stirring. Under the stirring of the stirrer 2, the concrete additives are mixed with water to form a turbid liquid downward. After stirring and mixing, it is discharged through the discharge pipe 6 and mixed with other raw materials of the concrete, so that the concrete additives are efficiently mixed with other raw materials and the mixing efficiency is improved.
[0021] Specifically, the discharging pipe 6 includes a water pipe joint 7, a material conveying pipe 8, a fixed water pipe 9, and an overflow pipe 10. The water pipe joint 7 is communicated with the bottom of the batching tank 1. The upper end of the water pipe joint 7 is communicated with the fixed water pipe 9, and the lower end is communicated with the material conveying pipe 8. The overflow pipe 10 is sleeved on the fixed water pipe 9 and can slide up and down along the fixed water pipe 9. Due to the function of the fixed water pipe 9, part of the water cannot be discharged from the batching tank 1, thereby preventing the concrete additive from condensing in the storage tank 4 due to drying in the batching tank 1. When batching, the concrete additive is continuously conveyed into the batching tank 1, and the stirrer 2 is used to continuously stir. At the same time, the water inlet pipe 5 continuously supplies water into the batching tank 1, and the liquid is discharged from the overflow pipe 10 when the water level rises. The overflow pipe 10 is slidably sleeved on the fixed water pipe 9, and the height of the overflow pipe 10 can be adjusted to control the liquid level height in the mixing tank, so as to adapt to different mixing requirements.
[0022] Specifically, a plurality of positioning holes 11 are provided on the outer side surface of the overflow pipe 10, and the fixed water pipe 9 is provided with positioning snap rings 12 that cooperate with the positioning holes 11. After adjusting the overflow pipe 10 to an appropriate height, the positioning snap ring 12 is inserted into the positioning hole 11 to fix the overflow pipe 10 and improve the stability of the overflow pipe 10.
[0023] Specifically, the stirrer 2 includes a motor 13, a cross bar 14, a longitudinal bar 15, and stirring blades 16. The output shaft of the motor 13 is connected to the cross bar 14. The longitudinal bar 15 is connected below the cross bar 14, and the stirring blades 16 are provided on the longitudinal bar 15. When the motor 13 rotates, it drives the cross bar 14 to rotate, and the cross bar 14 drives the longitudinal bar 15 and the stirring blades 16 on the longitudinal bar 15 to rotate, thereby fully stirring the concrete additive and water in the batching tank 1.
[0024] Embodiment 2
[0025] Please refer to the attached Figure 2 In this embodiment, the difference from Embodiment 1 is that a vertical guiding groove 17 is provided on the outer side wall of the overflow pipe 10, a guiding protrusion 18 that cooperates with the guiding groove 17 is provided on the inner side wall of the fixed water pipe 9, a spiral spring 19 is provided at the bottom of the overflow pipe 10, the lower end of the spiral spring 19 is connected to the fixed water pipe 9, and an inclined guide vane 24 is provided on the outer side wall of the overflow pipe 10. During the stirring process, the liquid rotates and flows in the batching tank 1, and the water flow impacts the guide vane 24 to generate a thrust force. When the water flow rotates forward, an upward thrust force is generated, and when it rotates backward, a downward thrust force is generated, thereby adjusting the height of the overflow pipe 10 without contacting the overflow pipe 10. The spiral spring 19 is used to drive the overflow pipe 10 to reset. The cooperation of the guiding groove 17 and the guiding protrusion 18 is used to prevent the overflow pipe 10 from rotating during the stirring process.
[0026] Specifically, the delivery pipe of the screw conveyor 3 is provided with a torsion spring 20 and a sealing cover 21. The sealing cover 21 is rotatably connected to the delivery pipe, and the torsion spring 20 drives the sealing cover 21 to rotate and cover the opening of the delivery pipe. After stopping the batching, the torsion spring 20 drives the sealing cover 21 to cover the delivery pipe, playing a role in moisture-proofing.
[0027] Specifically, a drain outlet 22 is provided at the bottom of the batching tank 1, and the drain outlet 22 is provided with a lid 23. The drain outlet 22 can be opened through the lid 23, and all the water can be drained after cleaning the batching tank 1.
[0028] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
