Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.
[0024] The utility model discloses an efficient sandstone sorting device, and the technical scheme of the utility model is:
[0025] As shown in Figure 1 - Figure 6 A kind of efficient sandstone sorting device, including screen body 1, vertical screen mesh 2 is fixedly connected in the inside of screen body 1, recess 3 is set in the both sides of screen body 1, turbine rotating rod 4 is rotatably connected with the inner side both ends of recess 3, the right side of turbine rotating rod 4 is extended outwardly and passes through the inner wall of screen body 1, first limiting block 5 is fixedly installed on the surface of turbine rotating rod 4, second limiting block 6 is fixedly installed on the surface of turbine rotating rod 4, rocker 7 is fixedly installed on the right side of second limiting block 6, multiple horizontal screen meshes 8 are rotatably connected with the side wall of recess 3, turbine 9 is fixedly installed on the surface of multiple horizontal screen meshes 8, symmetrically arranged installation side plate 10 is fixedly installed on the both sides of screen body 1, rotating rod 11 is rotatably connected between installation side plate 10, cam 12 is fixedly installed on the surface of rotating rod 11, motor 13 is fixedly installed on the side of installation side plate 10, base 14 is arranged on the lower surface of screen body 1, symmetrically arranged connecting block 15 is fixedly installed on the lower surface of screen body 1, symmetrically arranged spring base 16 is fixedly installed on the upper surface of base 14, buffer spring 17 is fixedly installed between connecting block 15 and spring base 16, collection plate 18 is fixedly installed on the inner wall of base 14.
[0026] Further, the vertical screen 2 is arranged in the same direction as the flow direction of the sand and gravel under the action of gravity, and is arranged vertically on the upper end of the horizontal screen 8. The vertical screen 2 and the horizontal screen 8 are arranged in cooperation to screen the sand and gravel. The vertical screen 2 is arranged in the direction to avoid the congestion of the sand and gravel during the screening process.
[0027] Further, the cam 12 is arranged in an arc shape with the upper end smaller than the lower end, and the axis of the cam 12 is different from that of the rotating rod 11. The cam 12 and the rotating rod 11 are arranged in cooperation. The centrifugal effect of the cam 12 causes the vibration of the screen body 1, and the efficiency of the screening is improved.
[0028] Further, the surface of the turbine rotating rod 4 is provided with a plurality of threads consistent with the number of the turbines 9. The threads are engaged with the turbines 9. The turbine rotating rod 4 drives the turbines 9 to rotate.
[0029] Further, the upper and lower sides of the horizontal screen 8 are arranged in parallel, the left and right sides of the horizontal screen 8 are arranged in an arc shape, and the length of the horizontal screen 8 is adapted to the size of the vertical screen 2.

[0031] Working principle: when in use, first, turn on the motor 13, then pour the sand and gravel to the right side of the screen body 1. When the power is turned on, the centrifugal force of the cam 12 causes the vibration of the screen body 1. The sand and gravel slides along the direction of the vertical screen 2. The sand and gravel with large diameter directly slides along the direction of the vertical screen 2 and falls to the ground. The sand and gravel with small diameter falls to the surface of the collecting plate 18 through the holes between the adjacent vertical screens 2 and horizontal screens 8. The sand and gravel with the same size is stuck. At this time, rotating the rocker 7 drives the horizontal screen 8 to rotate, the distance between the adjacent horizontal screens 8 increases, and the sand and gravel falls to the surface of the collecting plate 18 again. With the passage of time, the sand and gravel with small diameter slides along the surface of the collecting plate 18 and finally falls to the ground. The sand and gravel with large diameter is vibrated by the centrifugal force of the cam 12, and then slides along the surface of the vertical screen 2 and falls to the ground.
