[0002] The sand and gravel separator, also known as the concrete sand and gravel separator, is the core equipment of the concrete recycling system. After the concrete tank truck is used, the mixing tank usually needs to be cleaned. Since the sewage after cleaning the mixing tank contains more useful components, such as sand and gravel, people usually separate the sewage to separate the sand and gravel for recycling.
[0003] At present, a vibrating sand and gravel separator is a more commonly used sand and gravel separator, which usually includes a screen seat and a screen frame arranged on the screen seat. The four corners of the bottom of the screen frame are connected with springs and connected to the screen seat through springs. A vibration motor is arranged at the bottom of the screen frame, and a screen is arranged inside the screen frame. When in use, the vibration motor is used as a vibration source to drive the screen frame to swing, so that the material on the screen is thrown up and moves forward in a straight line. The screen can separate the sand and gravel, so that the stone moves along the front end direction of the screen frame and is discharged through the stone outlet opened thereon, while the sand leaks through the screen holes of the screen and is finally discharged through the sand outlet, thereby realizing sand and gravel separation. However, after long-term use of the equipment, fine sand will adhere to the screen holes of the screen, which may easily cause the screen to be blocked and affect the screening effect. For this reason, the screen needs to be cleaned regularly, and the screen is fixedly connected to the inside of the screen frame and is difficult to disassemble, resulting in troublesome, time-consuming and labor-intensive operation of cleaning the screen.
