After being fully mixed with raw materials such as cement, concrete can be made. Before the sand and gravel raw materials are used, a sorting device is needed to remove the sand and gravel with larger particles. Sand and gravel are easy to compact into blocks, so they need to be gathered and dispersed before they can be sorted.

[0003] According to the application number 202223478962.7, a sand and gravel sorting device for civil engineering is disclosed, which can make the fan blades rotate, and then the dust generated during falling and screening is sucked into the connecting box through the dust hood and the connecting pipe and filtered by the filter plate, thereby preventing the dust from being discharged to the outside and absorbed by the staff, thereby protecting the health of the staff.

[0004] The following problems still exist in actual use:

[0005] (1) In the above-mentioned equipment, the dust generated during screening is sucked in by a dust hood to prevent the dust from flying around.

[0033] In the utility model, the working steps of the device are as follows:

[0034] The first step: add sand and gravel into the box body 1 from the feed port 2. The sand and gravel first fall on the screening mesh plate 6. Start the vibration platform 13 to drive the box body 1 to vibrate, thereby driving the screening mesh plate 6 and the screening mesh plate 2 7 to vibrate. The sand and gravel on the surface are preliminarily screened by the vibration of the screening mesh plate 6. The screened sand and gravel continue to fall on the screening mesh plate 2 7 for secondary screening. When a large amount of dust is generated during the screening process, the dust removal pipe 3 is connected to an external vacuum cleaner to make the dust removal hood 4 generate suction to suck in the generated dust to achieve the dust removal effect. When the dust removal angle needs to be adjusted, the motor 508 is started to drive the arc plate 50 6 rotates, so that the arc plate 1 506 pushes the movable rod 505 to slide in the slide groove 503, and at the same time makes the movable rod 505 slide in the hollow part of the arc plate 2 507, and at the same time drives the dust cover 4 to move along the hollow part of the arc plate 2 507, and adjusts the dust removal angle of the dust cover 4, cooperates with the starting motor 2 509 to drive the arc plate 2 507 to rotate, can drive the movable rod 505 to slide inside the arc plate 1 506, can drive the dust cover 4 to move in another direction, two motors can control the movement of the dust cover 4 in two directions, and cooperate with each other to realize multi-angle adjustment, so as to perform all-round dust removal in the box body 1 and increase the dust removal efficiency;

[0035] The second step: when the screening mesh plate 1 6 or the screening mesh plate 2 7 is blocked by sand and gravel due to long-term work, the personnel can turn the hand wheel 806, and at the same time drive the transmission gear 807 to rotate, and drive the screw 802 to rotate through the driven gear 805, thereby driving the movable block 803 to move upward, and finally drive the insertion rod 804 to move upward. When the insertion rod 804 is completely disengaged from the slot 10, the screening mesh plate 1 6 or the screening mesh plate 2 7 can be pulled out from the interior of the box 1, and then the blocked part can be cleaned. After cleaning, it can be reinserted into the interior of the box 1, and the hand wheel 806 is rotated in the opposite direction to move the insertion rod 804 downward into the interior of the slot 10 to re-fix the screening mesh plate.
