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

[0013] 1. For the screening device for collecting stones of fixed specifications in a quarry, by setting a screening mechanism, when screening the size of stones, first, three fixed plates are equidistantly distributed inside the slots opened on the screening plate, so that four equidistant screening slots are formed inside the three fixed plates and the slots. And a movable plate is slidably connected inside the fixed plate, so that the movable plate can be pushed to move inside the fixed plate. When the movable plate moves a certain distance, since both sides of the upper surface of the movable plate are respectively connected to the first screw rod, and the first screw rod moves inside the chute opened on the fixed plate, the first screw rod moves a certain distance accordingly. At this time, according to the size of the screened stones, the caliber of the screening slot can be controlled from top to bottom through the movable plate. After the adjustment is completed, the rotating circular plate on the outer surface of the first screw rod can be rotated so that the lower surface of the rotating circular plate abuts against the upper surface of the fixed plate, thereby restricting the caliber size of the adjusted screening slot. Through the operation of the conveyor belt, the stones are conveyed to the platform of the screening plate, and by the principle of natural rolling, the stones roll on the surface of the screening plate. Stones of different sizes enter the inside of screening slots with different caliber sizes respectively, achieving the effect of screening stones. The setting of this structure can effectively screen stones of different specifications and fixed specifications, and the caliber of the screening slot can be adjusted according to the actual required stone size, thus avoiding the situation where the screening size is not adjustable and meeting the actual screening requirements. By the way of natural rolling, the situation of scattered stones during screening is avoided.

When adjusting the angle of the screening plate, one side of the screening plate is rotatably connected to the inside of the bearing block, and both ends of the lower surface of the other side of the screening plate are connected with connecting top blocks. The inside of the hinge seat is hinged to the connecting top block, and the lower surface inside of the hinge seat is rotatably sleeved with a second screw rod. The second screw rod is threadedly connected to the adjusting circular block rotatably sleeved inside the support rod. By rotating the adjusting circular block, the second screw rod can move up and down inside the support rod, so that the angle of the screening plate can be adjusted to control the rolling rate of the stones. The setting of this structure can control the rolling rate of the stones by controlling the angle of the screening plate, avoiding the situation that the rolling rate is too fast to be screened, and can select the angle of the screening plate according to the actual situation, improving the screening efficiency of the stones.

The inside of the rotating circular plate 13 is threadedly connected to the outer surface of the first screw 11. On the other side of the bearing block 1, there is a conveyor belt 2. The three groups of fixing plates 10 are evenly distributed inside the notch 8 formed on the screening plate 7, so that four groups of equally spaced screening slots 9 are formed inside the three groups of fixing plates 10 and the notch 8. And the inside of the fixing plate 10 is slidably connected with the movable plate 22, so as to push the movable plate 22 to move inside the fixing plate 10. When the movable plate 22 moves a certain distance, since both sides of the upper surface of the movable plate 22 are respectively connected to the first screw 11, and the first screw 11 moves inside the chute 12 formed on the fixing plate 10, the first screw 11 moves a certain distance accordingly. At this time, according to the size of the screened stones, the diameter of the screening slot 9 can be controlled from top to bottom through the movable plate 22. After the adjustment is completed, the rotating circular plate 13 on the outer surface of the first screw 11 can be rotated so that the lower surface of the rotating circular plate 13 abuts against the upper surface of the fixing plate 10, thereby restricting the adjusted diameter of the screening slot 9. Through the operation of the conveyor belt 2, the stones are conveyed to the platform of the screening plate 7, and by the principle of natural rolling, the stones roll on the surface of the screening plate 7, and stones of different sizes enter the inside of screening slots 9 with different diameters respectively.

At this time, according to the size of the screened stones, the caliber size of the screening slot 9 can be controlled from top to bottom through the movable plate 22. After the adjustment is completed, the rotating circular plate 13 on the outer surface of the first screw 11 can be rotated so that the lower surface of the rotating circular plate 13 abuts against the upper surface of the fixed plate 10, thereby restricting the caliber size of the adjusted screening slot 9. Through the operation of the conveyor belt 2, the stones are conveyed to the platform of the screening plate 7. According to the principle of natural rolling, the stones roll on the surface of the screening plate 7. Stones of different sizes respectively enter the inside of the screening slots 9 with different caliber sizes and are discharged into the corresponding external collection devices through the collection frame 5 arranged at the bottom of the screening plate 7.
