The control switch group 6 is arranged on the left side of the front surface of the screening box 1. The input end of the control switch group 6 is electrically connected to an external power source. It also includes a viewing window 10. The viewing window 10 is arranged on the right side of the upper surface of the screening box 1. Before the operation of processing traditional Chinese medicine decoction pieces, it is necessary to select slices with qualified specifications. At this time, the slices are slowly poured into the interior of the screening box 1 from the feeding hopper 5 through a lifting device;

[0026] Screening movement mechanism 2: It includes a screening plate 21, a chute 22, a rotating rod 23, an eccentric wheel 24, a rounded arc-shaped groove 25, an arc-shaped slider 27, and a return spring 28. The screening plate 21 is rotatably connected between the front and rear inner walls of the screening box 1 in the middle through a first rotating shaft. On the upper surface of the screening plate 21, chutes 22 are symmetrically arranged at the front and rear on the right side. A rotating rod 23 is rotatably connected between the front and rear inner walls of the screening box 1 on the upper right side. Eccentric wheels 24 are symmetrically arranged on the outer arc surface of the rotating rod 23 at the front and rear. The outer arc surfaces of the two eccentric wheels 24 are both slidably connected to the inner arc surface of the chute 22 on the same side. Rounded arc-shaped grooves 25 are opened on the right sides of the front and rear inner walls of the screening box 1. Arc-shaped sliders 27 are slidably connected inside the rounded arc-shaped grooves 25. The two arc-shaped sliders 27 are rotatably connected to the outer surface of the screening plate 21 through a second rotating shaft. A return spring 28 is provided between the lower surface of the arc-shaped slider 27 and the bottom inner wall of the rounded arc-shaped groove 25. The screening movement mechanism 2 further includes arc-shaped limiting rods 26, which are respectively fixedly connected to the inside of the two rounded arc-shaped grooves 25. The outer arc surfaces of the arc-shaped limiting rods 26 are respectively slidably connected to the middle parts of the arc-shaped sliders 27 located inside the same rounded arc-shaped groove 25. The two return springs 28 are respectively movably sleeved on the outer arc surfaces of the arc-shaped limiting rods 26 on the same side. It also includes a screening motor 3, which is arranged on the right side of the rear surface of the screening box 1. The output shaft of the screening motor 3 is fixedly connected to the rear end of the rotating rod 23. The input end of the screening motor 3 is electrically connected to the output end of the control switch group 6. It also includes an electric feeding conveyor belt 4, which is arranged on the left side inside the screening box 1. The electric feeding conveyor belt 4 corresponds to the screening plate 21 in the left-right position. The input end of the electric feeding conveyor belt 4 is electrically connected to the output end of the control switch group 6. It also includes a feeding hopper 5, which is arranged on the left side of the upper surface of the screening box 1. The feeding hopper 5 corresponds to the electric feeding conveyor belt 4 in the up-down position. A slag discharge hopper 7 is provided on the lower surface of the right side of the screening box 1. The screening plate 21 corresponds to the slag discharge hopper 7 in the up-down position. A waste material box 8 is placed below the slag discharge hopper 7. An outlet guiding hopper 9 is provided on the right side of the screening box 1. The outlet guiding hopper 9 corresponds to the screening plate 21 in the left-right position. At this time, by adjusting the control switch group 6, the electric feeding conveyor belt 4 operates, and the raw materials of traditional Chinese medicine slices are dropped onto the screening plate 21 at a specified rate. At this time, the control switch group 6 can be adjusted, and the screening motor 3 operates. The output shaft of the screening motor 3 rotates slowly, and then drives the two eccentric wheels 24 to rotate slowly through the rotating rod 23. When the eccentric wheel 24 rotates from the proximal end to the distal end, it will push the screening plate 21 to change clockwise by twenty degrees with its left side as the axis. This changing force overcomes part of the tensile force of the return spring 28. During this period, it will be affected by the elastic force of the return spring 28 to ensure the stability of the screening plate 21 during the clockwise change. When the eccentric wheel 24 rotates from the distal end to the proximal end, the eccentric wheel 24 loses the extrusion of the screening plate 21. At this time, affected by the tensile force of the return spring 28, the screening plate 21 will return to its original position. Thus, the reciprocating operation of the screening plate 21 at a specified angle is repeated continuously.The Chinese medicinal material slices raw materials that fall on the upper surface of the vibrating sieve plate 21 are vibrated while moving to the right. The Chinese medicinal material slices raw materials on the vibrating sieve plate 21 will maintain a loose quantity. During vibration, the Chinese medicinal material slices raw materials with smaller specifications will fall through the sieve holes of the vibrating sieve plate 21, and fall into the waste box 8 along the guide of the slag discharge hopper 7. The qualified Chinese medicinal material slices raw materials will continue to move to the right and then fall outside the device along the discharge guiding hopper 9.

[0027] The working principle of a screening machine for processing Chinese medicinal material slices provided by the present utility model is as follows: Before the operation of processing Chinese medicinal material slices, it is necessary to select slices with qualified specifications. At this time, the slices are slowly poured into the interior of the screening box 1 from the feeding hopper 5 through a lifting device. At this time, the control switch group 6 can be adjusted to make the electric feeding conveyor belt 4 operate, and the Chinese medicine slice raw materials are dropped onto the vibrating sieve plate 21 at a specified rate. At this time, the control switch group 6 can be adjusted to make the screening motor 3 operate. The output shaft of the screening motor 3 rotates slowly, and then drives two eccentric wheels 24 to rotate slowly through the rotating rod 23. When the eccentric wheel 24 rotates from the proximal end to the distal end, it will push the vibrating sieve plate 21 to make a 20-degree clockwise change with its left side as the axis. This changing force overcomes part of the stretching force of the return spring 28. During this period, it will be affected by the elastic force of the return spring 28 to ensure the stability of the vibrating sieve plate 21 during the clockwise change. When the eccentric wheel 24 rotates from the distal end to the proximal end, the eccentric wheel 24 loses the extrusion of the vibrating sieve plate 21. At this time, affected by the stretching force of the return spring 28, the vibrating sieve plate 21 will return to its original position. Thus, the reciprocating operation of the vibrating sieve plate 21 at a specified angle is repeated all the time, so that the Chinese medicinal material slices raw materials that fall on the upper surface of the vibrating sieve plate 21 are vibrated while moving to the right. The Chinese medicinal material slices raw materials on the vibrating sieve plate 21 will maintain a loose quantity. During vibration, the Chinese medicinal material slices raw materials with smaller specifications will fall through the sieve holes of the vibrating sieve plate 21, and fall into the waste box 8 along the guide of the slag discharge hopper 7. The qualified Chinese medicinal material slices raw materials will continue to move to the right and then fall outside the device along the discharge guiding hopper 9.

[0028] It should be noted that the screening motor 3 and the electric feeding conveyor belt 4 disclosed in the above embodiments can be freely configured according to the actual application scenarios. It is recommended to select a 42PG series planetary reduction stepping motor for the screening motor 3, and it is recommended to select a conventional electric conveyor line for the electric feeding conveyor belt 4. The control switch group 6 is provided with control buttons corresponding to the screening motor 3 and the electric feeding conveyor belt 4 one by one and used to control their switches.

[0029] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
