Elastic components are provided inside the mounting grooves 10, and the two elastic components are respectively engaged with the two engaging grooves 13, wherein the elastic components include an engaging spring 11 fixedly mounted on the inner wall of the mounting groove 10, and an engaging key 12 mounted on the engaging spring 11, wherein the engaging key 12 is engaged with the engaging groove 13, so that the elastic force of the two engaging springs 11 can be stretched to enable the two engaging keys 12 to maintain a tendency to move toward the two engaging grooves 13 until the two engaging keys 12 are respectively stably engaged with the two engaging grooves 13, thereby achieving the effect of fixing the positioning seat 2, and further achieving the effect of fixing the filter screen 5.

[0026] In this embodiment, an elastic spring 3 is installed between the inner bottom wall of the positioning seat 2 and the bottom of the filter screen 5. Through the elastic force of the expansion and contraction of the elastic spring 3, when the workpiece falls onto the filter screen 5, the filter screen 5 can vibrate by itself, thereby effectively avoiding clogging of the filter screen 5.

[0027] In this embodiment, a limit slot 14 is vertically provided between two opposite inner walls of the positioning seat 2, and a limit slider 15 is installed on two separated side walls of the filter screen 5, wherein the two limit sliders 15 are respectively slidably connected to the two limit slots 14. By means of the two limit sliders 15 being respectively slidably connected to the two limit slots 14, the filter screen 5 can only vibrate up and down but cannot rotate, thereby achieving the effect of limiting the filter screen 5.

[0028] In this embodiment, a motor 6 is installed on the side wall of the lower hopper 1, a rotating shaft 8 is installed on the output shaft of the motor 6, and a cam 7 is installed on the end of the rotating shaft 8 away from the output end of the motor 6, wherein the bottom of the cam 7 is movably connected to the upper surface of the filter screen 5, so that the rotating shaft 8 can achieve the effect of automatic rotation through the rotation of the output shaft of the motor 6, and then the cam 7 can achieve the effect of automatic rotation, and then the rotation of the cam 7 can achieve the effect of hitting the filter screen 5, and the rotation speed of the cam 7 can be adjusted by adjusting the rotation speed of the rotating shaft 8, thereby achieving the effect of adjusting the vibration frequency of the filter screen 5.

[0029] In this embodiment, a slope 9 is installed on the positioning seat 2, wherein the lowest point of the slope 9 is close to the upper surface of the filter screen 5. By installing the slope 9, the workpieces falling into the inner edge of the lower hopper 1 can slide onto the filter screen 5 and be filtered, thereby avoiding the accumulation of workpieces inside the lower hopper 1.

[0030] Working principle: Press the positioning seat 2 from the top of the lower hopper 1 to the inside of the lower hopper 1 until the two snap-in keys 12 move to the two snap-in grooves 13. The two snap-in keys 12 can be stably snap-fitted with the two snap-in grooves 13 through the elastic force of the extended snap-in spring 11, thereby achieving the effect of fixing the positioning seat 2 and the filter screen 5. During the filtering process, start the motor 6 to rotate the rotating shaft 8 and the cam 7, and then the cam 7 hits the filter screen 5, so that the filter screen 5 can filter the workpiece more effectively through vibration, thereby improving the filtration efficiency of the filter screen 5, and at the same time preventing the workpiece from clogging the filter screen 5.
