DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0027] Reference Figure 1-Figure 5 A multi-stage calcium stone screening device comprises a base 1 and a fixed column 2. A plurality of groups of screening nets 3 are arranged on the top of the base 1. A fixed block 4 is fixedly connected to the top of the plurality of groups of screening nets 3. A screw rod 5 is rotatably connected to the side of the fixed block 4 through a bearing. Two moving blocks 6 are connected to the surface of the screw rod 5 through a thread. A driving member 26 is fixedly connected to the end of the screw rod 5. A fixed frame 7 is fixedly connected to the top of one moving block 6. A U-shaped frame 8 is slidably connected to the inner wall of the fixed frame 7. A reset spring 9 is fixedly connected between the fixed frame 7 and the U-shaped frame 8. A rectangular plate 10 is fixedly connected to the bottom of the U-shaped frame 8. A toggle plate 11 is arranged at the bottom of the rectangular plate 10.

[0028] In the present invention, the feeding method of calcium stone is set to intermittent feeding. When the calcium stone needs to be screened, the calcium stone is firstly fed to the side of the U-shaped frame 8 close to the first collecting box 19. Since the toggle plate 11 is always in a fit state with the screening net 3, when the calcium stone is always fed, the toggle plate 11 will push the first batch of calcium stone to move. When the U-shaped frame 8 moves in a direction away from the first collecting box 19, the toggle plate 11 will push the subsequent calcium stone to form an accumulation at the highest point in the screening net 3, which is not conducive to the subsequent screening of the calcium stone. Therefore, the feeding method of calcium stone is set to intermittent feeding;

[0029] When calcium stone is put into the screening net 3, it will roll along the slope of the screening net 3 so that it can be screened. Due to the different sizes of calcium stones, some of the calcium stones will be stuck in the mesh of the screening net 3 during the screening process. At this time, the driving member 26 is driven to work, so that the driving member 26 drives the screw rod 5 to rotate, and then the screw rod 5 drives the moving block 6 and the fixed frame 7 to move, and at the same time, the fixed frame 7 drives the U-shaped frame 8 and the return spring 9 to move, and the U-shaped frame 8 drives the rectangular plate 10 and the toggle plate 11 to move synchronously. Since the screening net 3 is set to be inclined, when the rectangular plate 10 and the toggle plate 11 are away from the driving member 26, the return spring 9 will drive the U-shaped frame 8 to move downward, and the toggle plate 11 will contact the top of the screening net 3, so as to facilitate the calcium stone stuck in the mesh of the screening net 3 to be toggled, so as to avoid the screening net 3 from being blocked and causing the screening efficiency to be seriously affected;

[0030] Therefore, intermittent feeding can be set to avoid the accumulation of calcium stone on the toggle plate 11 when the toggle plate 11 moves away from the first collecting box 19.

[0031] The driving member 26 is a sprocket or a chain, and the sprocket is installed on the screw rod 5 .

[0032] Reference Figure 3 A first connecting block 12 is fixedly connected to the side of the rectangular plate 10, a second connecting block 13 is fixedly connected to the side of the toggle plate 11, a bolt 14 is provided on the inner wall of the first connecting block 12, and the surface of the bolt 14 is movably connected to the second connecting block 13 through a thread.

[0033] In the utility model, since the calcium stone is damaged due to long-term use of the toggle plate 11, the staff can rotate the bolt 14 by a hand-held tool to disengage the bolt 14 from the second connecting block 13, so that the staff can disassemble and replace the toggle plate 11, thereby improving the use efficiency of the screening device.

[0034] Reference Figure 3 A hexagonal groove 15 and a cross groove 16 are respectively formed on the top of the bolt 14, and the hexagonal groove 15 and the cross groove 16 are connected.

[0035] In the utility model, by providing the hexagonal groove 15 and the cross groove 16 , it is convenient for the staff to use two tools to rotate the bolt 14 , thereby effectively increasing the practicability of the screening device.

[0036] Reference Figure 3 A placement groove 17 is provided on the top of the first connecting block 12, and the placement groove 17 is circular in shape.

[0037] In the present invention, the bolt 14 can be placed by setting the placement groove 17, so as to avoid the bolt 14 protruding on the first connecting block 12 and affecting the appearance.

[0038] Reference Figure 3 A locking piece 18 is movably connected to the surface of the bolt 14 , and the inner wall of the placement groove 17 is movably connected to the locking piece 18 .

[0039] In the present invention, by providing the locking piece 18, the locking degree between the bolt 14 and the first connecting block 12 can be strengthened to avoid loosening during use and affecting subsequent normal use.

[0040] Reference Figure 1-Figure 5 A first collecting box 19 is fixedly connected to the side of the screening net 3, and a second collecting box 20 is movably connected to the top of the base 1.

[0041] In the utility model, the screened calcium stones can be collected by setting the first collecting box 19 and the second collecting box 20, so that it is convenient for subsequent staff to uniformly process the calcium stones.

[0042] Reference Figure 1 A guide rod 21 is fixedly connected to the side of the fixed block 4, the surface of the guide rod 21 is slidably connected to another moving block 6, and the top of the other moving block 6 is fixedly connected to the fixed frame 7.

[0043] In the present invention, the guide rod 21 is provided to limit the position of the fixing frame 7, so as to prevent the screw rod 5 from driving the moving block 6 and the fixing frame 7 to flip over and affect subsequent use.

[0044] Reference Figure 1-Figure 4 A gantry 22 is fixedly connected to the surface of the fixed column 2, an electric push rod 23 is fixedly connected to the side of the gantry 22, a connecting plate 24 is fixedly connected to the output end of the electric push rod 23, the side of the connecting plate 24 is fixedly connected to multiple groups of screening nets 3, a slide groove 25 is opened on the surface of the screening net 3, a slider 27 is slidably connected to the inner wall of the slide groove 25, and the surface of the slider 27 is fixedly connected to the fixed column 2.
