[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example:

[0021] like Figures 1 to 4 As shown, a recycled concrete aggregate screening device includes a body 1, a screening mechanism 2 installed inside the body 1 for screening the recycled concrete aggregate, a material distribution mechanism 3 installed on the top of the body 1 for evenly spreading the recycled concrete aggregate, a feeding mechanism 4 installed inside the body 1, and a cleaning mechanism 5 that cooperates with the screening mechanism 2 installed inside the body 1.

[0022] The screening mechanism 2 can not only screen the recycled concrete aggregate, but also automatically adjust the screening position to avoid clogging of the screening holes, extend the screening distance, and improve the screening effect. The material equalization mechanism 3 can perform material equalization operation on the recycled concrete aggregate on the screening mechanism 2 to avoid accumulation and affect the screening effect. The material discharge mechanism 4 can facilitate the collection of the two types of recycled concrete aggregate after screening. The cleaning mechanism 5 can automatically clear blockages in the screening mechanism 2 and reduce the workload.

[0023] It should be noted that in this technical solution, support legs are installed around the bottom of the machine body 1, and a vibration motor is installed at the bottom of the machine body 1. The vibration motor can vibrate the machine body 1 to improve the screening effect. Furthermore, a controller 6 is fixedly installed on one side of the outer surface of the machine body 1. The controller 6 facilitates the control of various mechanisms. The controller 6 is a commonly used technical means in this field and belongs to the prior art.

[0024] like Figures 1 to 3As shown, the screening mechanism 2 includes four conveyor rollers 21 rotatably connected inside the machine body 1. A belt screening belt 22 is sleeved between the four conveyor rollers 21. Multiple rows of screening holes are sequentially opened on the outer surface of the belt screening belt 22. A motor 23 is fixedly installed on one side of the outer surface of the machine body 1. The output shaft of the motor 23 is fixedly connected to one end of the adjacent conveyor roller 21. The two conveyor rollers 21 located at the top are arranged vertically.

[0025] The recycled concrete aggregate can be screened by the set belt screening belt 22, and the rotation of the motor 23 can drive the belt screening belt 22 to rotate. This can not only change the screening position and avoid clogging that affects the screening effect, but also extend the distance of the recycled concrete aggregate on the belt screening belt 22, thereby improving the screening effect.

[0026] like Figures 1 to 3 As shown, the material distribution mechanism 3 includes a horizontal plate 31 fixedly connected to the top of the machine body 1. An electric push rod 32 is fixedly installed on the top of the horizontal plate 31, and a material distribution baffle 33 is fixedly connected to the bottom end of the electric push rod 32. A material distribution hopper 34 is fixedly installed on one side of the top of the machine body 1.

[0027] Recycled concrete aggregate is evenly distributed onto the belt screening belt 22 through the equalization hopper 34, and the electric push rod 32 can drive the equalization baffle 33 to move up and down, which can further equalize the recycled concrete aggregate and avoid accumulation that would affect the screening effect.

[0028] like Figures 1 to 3 As shown, the feeding mechanism 4 includes a first guide frame 41 fixedly connected inside the machine body 1. One end of the first guide frame 41 extends to the outside of the machine body 1, and the first guide frame 41 is located inside the belt screening belt 22. A guide plate 42 is fixedly connected to the bottom inner side of the machine body 1, and a second guide frame 43 that cooperates with the guide plate 42 is fixedly connected to one side of the machine body 1.

[0029] The first guide frame 41 can collect the recycled concrete aggregate after screening, while the guide plate 42 and the second guide frame 43 can collect larger recycled concrete aggregate.

[0030] like Figures 3 to 4 As shown, the cleaning mechanism 5 includes a connecting plate 51 fixedly connected inside the machine body 1. A spring 52 is fixedly connected to the lower surface of the connecting plate 51. A mounting plate 53 is fixedly connected to the bottom end of the spring 52. A plurality of conical protrusions 54 that cooperate with the screening holes are fixedly connected to the lower surface of the mounting plate 53 in sequence. A guide rod 55 that is slidably connected to the inside of the connecting plate 51 is fixedly connected to the top end of the mounting plate 53.

[0031] When the motor 23 drives the belt screening belt 22 to rotate, when the screening hole coincides with the conical protrusion 54, the conical protrusion 54 can be pushed into the screening hole by the cooperation of the spring 52, which can clear the blockage of the screening hole.

[0032] Working principle: Recycled concrete aggregate is evenly distributed onto the belt screening belt 22 through the equalization hopper 34. The electric push rod 32 can drive the equalization baffle 33 to move up and down, which can further equalize the recycled concrete aggregate and avoid accumulation that would affect the screening effect. The belt screening belt 22 can screen the recycled concrete aggregate. The rotation of the motor 23 can drive the belt screening belt 22 to rotate, which can not only change the screening position to avoid blockage affecting the screening effect, but also extend the distance of the recycled concrete aggregate on the belt screening belt 22, thereby improving the screening effect. The first guide frame 41 can collect the recycled concrete aggregate that has been screened, while the guide plate 42 and the second guide frame 43 can collect larger recycled concrete aggregate. When the motor 23 drives the belt screening belt 22 to rotate, when the screening hole coincides with the conical protrusion 54, the conical protrusion 54 can be pushed into the screening hole with the cooperation of the spring 52, which can clear the blockage of the screening hole.

[0033] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
