DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Specific examples are given below.
[0026] See also Figure 1 - Figure 5 The utility model provides a recycled concrete screening device, including a body 1, a material injection port 2, a material discharge port 3 and a screening drum 4. The material injection port 2 is fixedly installed at one end of the top of the body 1, and one end of the material injection port 2 is fixedly connected to a material guide pipe 21. The material discharge port 3 is installed on one side of the body 1, and the screening drum 4 is arranged inside the body 1. A connecting port 41 is opened on one side of the screening drum 4, and the outer wall of the connecting port 41 is rotatably connected to the outer wall of one end of the material guide pipe 21. A first screen 42 is fixedly connected to one end of the connecting port 41, and a spiral blade 44 is fixedly connected to the inside of the first screen 42. A second screen 43 is sleeved on the outer side of the first screen 42, and one end of the second screen 43 is also fixedly connected to the inner wall of one side of the screening drum 4. A spiral blade 44 is fixedly connected between the first screen 42 and the second screen 43, and another spiral blade 44 is also fixedly connected to the outer wall of the second screen 43. And the outer wall of one side of the other spiral blade 44 is fixedly connected to the inner wall of the screening drum 4. A circular groove 12 is provided on the inner wall of one side of the body 1, and the outer wall of one end of the circular groove 12 is rotatably connected to the inner wall of the circular groove 12, and a plurality of sealing rings 13 are fixedly connected inside the circular groove 12. One side of each sealing ring 13 is fixedly connected to the discharge port 3, and one side of each sealing ring 13 is rotatably connected to the outer wall of one side of the screening cylinder 4 through the circular groove 12. One end of the first screen 42 and the second screen 43 are both attached to one side of a sealing ring 13 through the screening cylinder 4.
[0027] During operation, the recycled concrete material enters the device through the injection port 2 located at one end of the top of the machine body 1. The injection port 2 is connected to a guide pipe 21 for guiding the material to enter the screening drum 4 smoothly. The connection port 41 can prevent the screening drum 4 from damaging the guide pipe 21 when it rotates. Two layers of screens are installed inside the screening drum 4, namely, a first screen 42 and a second screen 43. A spiral blade 44 is fixedly connected between the two layers of screens and on their outer sides. The material is pushed and turned by the spiral blade 44 inside the screening drum 4, so that the material is turned and dispersed. Since the apertures of the first screen 42 and the second screen 43 are different, the material with a smaller particle size can pass through the first screen 42 while the material with a larger particle size is intercepted by the second screen 43. In this way, the two layers of screens realize the classification of the material. The spiral blade 44 is used to rotate inside the screening drum 4 to push the material to move toward the discharge port 3, and at the same time, the material is fully mixed and screened. The screened material is discharged through the discharge port 3 of the machine body 1. The discharge port 3 is connected to a plurality of sealing rings 13, which are rotatably connected to the outer wall of one end of the screening cylinder 4 through the circular groove 12 to ensure the sealing of the discharge process and prevent the material from scattering during the discharge process. The discharge port 3 has three material separation plates, so that the material discharged through the discharge port 3 can be discharged in stages to prevent the screened materials from being mixed together again, thereby completing the screening process. The above-mentioned method can make the concrete raw materials of different sizes separated completely, without the need for secondary screening, which can improve the quality of concrete raw material screening and improve the practicality of the equipment.
[0028] Further, such as Figure 2 As shown, a driving motor 11 is fixedly connected inside the machine body 1, and a transmission gear 10 is fixedly connected to the middle of the output shaft of the driving motor 11. The outer wall of the transmission gear 10 is meshedly connected with a toothed collar 9, and the inner wall of the toothed collar 9 is fixedly connected to the outer wall of one end of the screening cylinder 4.
[0029] During operation, when the material enters the screening drum 4 through the injection port 2, the drive motor 11 is started, and the output shaft of the drive motor 11 drives the transmission gear 10 to rotate, and then the meshing of the transmission gear 10 and the toothed collar 9 can drive the screening drum 4 to rotate, so that the material turns over inside the screening drum, accelerating the screening of concrete.
[0030] Further, such as Figure 3As shown, the outer walls at both ends of the screening drum 4 are fixedly connected with positioning collars 5, and the outer wall of each positioning collar 5 is provided with a limiting groove 51, and the interior of each limiting groove 51 is rotatably connected with two rollers 6. The middle part of each roller 6 is fixedly connected with a connecting rod 7, and the two ends of each connecting rod 7 are rotatably connected with a positioning frame 8. The bottom of each positioning frame 8 is fixedly connected to the inner wall of the machine body 1, and each roller 6 rotates with the top of the positioning frame 8 via the connecting rod 7. Every two adjacent rollers 6 are symmetrically arranged on both sides of the screening drum 4 via the positioning frame 8, and the screening drum 4 rotates inside the machine body 1 via the positioning collar 5 and the rollers 6.
[0031] During operation, when the driving motor 11 drives the screening drum 4 to rotate through the transmission gear 10 and the toothed collar 9, the screening drum 4 will rotate around the roller 6 on the positioning collar 5. The roller 6 rotates in the limiting groove 51, allowing the screening drum 4 to rotate inside the machine body 1. The symmetrical layout between two adjacent rollers 6 can maintain the balance of the screening drum 4 during rotation, ensuring the stable rotation of the screening drum 4 inside the machine body 1. The positioning frame 8 rotatably connected at both ends of the connecting rod 7 is used to ensure the stability of the roller 6, and the positioning frame 8 is fixedly connected to the machine body 1 to ensure the stability of the entire structure. The use efficiency and service life of the device are improved.
[0032] Working principle: The recycled concrete material enters the equipment through the injection port 2 located at one end of the top of the machine body 1. The injection port 2 is connected to a guide pipe 21 for guiding the material to enter the screening drum 4 smoothly. The drive motor 11 is started, and the output shaft of the drive motor 11 is used to drive the transmission gear 10 to rotate, and then the meshing of the transmission gear 10 and the toothed collar 9 can drive the screening drum 4 to rotate. The screening drum 4 will rotate around the roller 6 on the positioning collar 5, and the roller 6 rotates in the limit groove 51, allowing the screening drum 4 to rotate inside the machine body 1. The first screen 42 and the second screen 43 and their outer sides are fixedly connected with spiral blades 44, so that the material is pushed and turned inside the screening drum 4 by the spiral blades 44. And because the apertures of the first screen 42 and the second screen 43 are different, the material with a smaller particle size can pass through the first screen 42, and the material with a larger particle size is intercepted by the second screen 43 again, so that the material classification is realized. The spiral blade 44 is used to rotate inside the screening cylinder 4 to push the material to move toward the discharge port 3. The screened material is discharged through the discharge port 3 of the machine body 1. The discharge port 3 has three dividing plates, so that the material discharged through the discharge port 3 can be discharged in grades, thereby completing the screening process.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
