[0003] The Chinese patent with publication number CN214865201U discloses a screening vibration table for concrete production, which includes a rotating rod, a movable block, a second servo motor, a scraping plate, a sliding sleeve, and a sliding rod. The second servo motor is installed on one side of the top end of the vibration cavity. A scraping mechanism is provided at the top end of the vibration cavity. The second servo motor is started to drive the rotating rod to rotate under the work of the second servo motor. Since the rotating rod is threadedly connected with the movable block, the movable block is moved. At this time, the sliding sleeve slides on the outer side wall of the sliding rod, thereby driving the scraping plate to move, which realizes the convenient scraping of the excess material inside the vibration cavity, thereby greatly improving the working efficiency of the vibration table during use.

[0004] The screening vibration table of the above-mentioned patent has the problem that the filtered material will be retained at the upper end of the screen during use, and the screen is difficult to clean during use of the equipment. The entire concrete inside the equipment needs to be discharged before cleaning. When the screen needs to be cleaned, the retained material will continue to affect the screening efficiency, resulting in reduced concrete screening efficiency. UTILITY MODEL CONTENTS

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] This invention enables different concrete flow trajectories by varying the inclination direction of the main screen during concrete screening. The longitudinally distributed upper fixing strips and secondary screens on both sides of the main screen adapt to it and assist in concrete screening. The inclined main screen causes the concrete to move towards the secondary screen during screening, and the concrete is also screened at the secondary screen. Material confined and retained at the top of both the main and secondary screens gradually slides towards the secondary screen as the concrete flows, resulting in material retention at the top of the secondary screen. The secondary screen can be directly removed and cleaned by sliding it through the sliding rail. Furthermore, when cleaning the secondary screen, the main screen's inclination direction can be adjusted by rotating it around the first handle. The inclination directions of the two secondary screens and the main screen can be interchanged, preventing the equipment from stopping concrete screening due to cleaning of the screened material.
