[0026] Furthermore, when the zero scale line of the scale 14 is aligned with the boundary of one side of the screening box 5, the screening box 5 and the rectangular screening slots in the adjusting screen plate 9 are not intercommunication but the boundaries of the rectangular screening slots are aligned, and the screw 12 passes through the fixed plate 11 and is threadedly connected. The moving distance of the adjusting screen plate 9 can be accurately controlled by the scale 14, so as to control the width of the intercommunication area of ​​the upper and lower rectangular screening slots, thereby realizing accurate sand and gravel particle size screening.

[0027] Furthermore, the screening mechanism 7 includes a slide bar 71 fixed at both ends of the screening box 5, the slide bar 71 passes through the inner cavity of the sorting machine body 3 and is slidably connected, and a spring 72 is arranged on the outer ring of the slide bar 71 located in the inner cavity of the sorting machine body 3.

[0028] Furthermore, one end of the screening box 5 is fixedly connected to a tooth plate 74, which passes through the inner cavity of the sorting machine body 3 and is slidably connected. A half-tooth gear 73 is meshed at the bottom of the tooth plate 74, and a motor 75 is fixedly connected to one side of the sorting machine body 3.
