[0024] Example 1: As Figures 1-4As shown, this utility model provides a technical solution: a concrete aggregate screening device, comprising: a screening mechanism 1, an auxiliary mechanism 2 disposed on the bottom side of the screening mechanism 1, the screening mechanism 1 including a main cavity 11, a screening roller 12 disposed on the inner surface of the main cavity 11, the inner surface of the main cavity 11 being rotatably connected to the outer surface of the screening roller 12, a semi-circular cavity 13 disposed on the inner surface of the screening roller 12, the inner surface of the screening roller 12 being rotatably in contact with the outer surface of the semi-circular cavity 13, and a folding rod 17 disposed at one end of the semi-circular cavity 13. One end of the semi-circular cavity 13 is rotatably connected to one end of the folding rod 17. A cylinder rod 16 is provided at the other end of the folding rod 17, and is fixedly connected to one end of the cylinder rod 16. One end of the cylinder rod 16 is fixedly connected to one side of the main cavity 11. An inner plate 110 is provided on the inner wall of the main cavity 11, and the inner wall of the main cavity 11 fits against the outer side of the inner plate 110. A discharge port 19 is opened on one side of the main cavity 11. A side rod 18 is provided at one end of the inner plate 110, and one end of the inner plate 110 is fixedly connected to one end of the side rod 18. The side rod 18 is fixedly connected to one side of the folding rod 17. A connecting rod 14 is provided on the top side of one end of the semi-circular cavity 13. The top side of one end of the semi-circular cavity 13 is slidably connected to the bottom end of the connecting rod 14. The other end of the connecting rod 14 is engaged with the inner surface of the locking hole 15 of the screening roller 12. A telescopic rod 112 is provided on one bottom side of the main cavity 11. The bottom side of the main cavity 11 is fixedly connected to the bottom end of the telescopic rod 112. A horizontal plate 113 is provided on the top end of the telescopic rod 112. The bottom side of the horizontal plate 113 is fixedly connected to the horizontal plate 113. The top side of the horizontal plate 113 is provided with a barrier rod 114. The bottom end of the barrier rod 114 is fixedly connected to the top side of the horizontal plate 113. The outer side of the barrier rod 114 is connected through the inner wall of the main cavity 11. The outer side of the barrier rod 114 is connected through the screen hole of the screening roller 12. A motor 111 is provided at one side end of the main cavity 11. The bottom side of the main cavity 11 is fixedly connected to the side of the motor 111. The output end of the motor 111 is fixedly connected to the center of the screening roller 12.

[0025] In this embodiment, when using this type of concrete aggregate screening device, the aggregate is poured into the main chamber 11, and then the motor 111 is started to make the screening roller 12 start rotating. The diameter of the hole of the screening roller 12 can separate the smaller aggregate into the inner surface of the screening roller 12. A semi-circular cavity 13 is designed on the inner surface. Therefore, when the smaller aggregate is separated, it will fall into the semi-circular cavity 13, which receives the smaller aggregate. After screening is completed, the cylinder rod 16 is extended to make the semi-circular cavity 13 slide out from the screening roller 12. When it slides to a certain extent, the connecting rod 14 is pushed into the lock. The semi-circular cavity 13 and the screening roller 12 are integrated within the hole 15. The motor 111 drives the screening roller 12 and the semi-circular cavity 13 to rotate 180 degrees simultaneously. As a result, smaller sand and gravel in the semi-circular cavity 13 fall out. However, as the cylinder rod 16 extends, the inner plate 110 is carried out from the discharge hole. At this point, the discharge channel for larger sand and gravel is opened. Simultaneously, the rotation of the screening roller 12 carries the larger sand and gravel into the discharge port 19 for discharge. This can achieve a relatively automated screening and discharge process, reduce the need for manual operation, and improve the safety and labor-saving of operation.

[0026] Secondly, by extending the telescopic rod 112, the obstacle removal rod 114 on the horizontal plate 113 is raised to a higher height. At this time, the hole on the screening roller 12 is aligned with the obstacle removal rod 114, and the obstacle removal rod 114 will enter the hole to push out the sand and gravel stuck in the hole. This effectively reduces production interruptions caused by material blockage, enhances the continuity of the entire production process, and thus improves the overall output and efficiency.

[0028] In this embodiment, a base support 21 is installed on the bottom side of the main cavity 11, and the bottom side of the base support 21 is connected to the rubber pad 22. Since the rubber pad 22 is responsible for contacting the ground, the flexible contact provided by the rubber pad 22 can increase the stability of the equipment during operation, avoid tilting or displacement of the equipment due to vibration, ensure balance during operation, effectively absorb the vibration generated by the equipment during operation, reduce the impact of vibration on the equipment and foundation, and extend the service life of the equipment.
