[0036] Example 1
[0037] like Figures 1-5 As shown, this embodiment provides a cleaning and screening device for the production of Polygonum multiflorum, including a cleaning box 1 and a screening cylinder 6. A hinged door 60 is provided on the outside of the cleaning box 1 corresponding to the screening cylinder 6. The door 60 is fixedly connected to the front wall of the cleaning box 1 by a cross lock. The cross lock is embedded in the left side of the door 60.
[0038] The top of the cleaning box 1 is provided with a feeding box 5. A blower 2 is installed on the upper left side of the cleaning box 1, and the air outlet 20 of the blower 2 is directly opposite the discharge port of the feeding box 5.

[0039] Before screening, the Polygonum multiflorum and its contained debris, impurities, and dust are fed into the feed box 5 and fall into the cleaning box 1. At this time, the blower 2 is started to blow the Polygonum multiflorum and impurities, thereby blowing the leaves, impurities, and debris of the original raw material, causing the debris and impurities to drift into the storage box 3, thus completing the initial removal of impurities from the Polygonum multiflorum.
[0040] The screening cylinder 6 is fixed inside the cleaning box 1. It has an inlet 101 at the top and an outlet 61 and a discharge port 62 at the bottom. The screening cylinder 6 contains a first screening mechanism, which includes a screen box 8, a slide rail 82, and a drive device 7. Water enters through the inlet 101 to clean the Polygonum multiflorum, and vibration screening removes surface dirt. The cleaned wastewater is discharged through the outlet 61.
[0041] The sieve box 8 is located below the discharge port of the feed box 5. The lower side wall of the sieve box 8 is provided with a plurality of sieve holes, and the outer side of the sieve box 8 is provided with a sliding part 81.
[0042] The slide rail 82 is located on the lower side of the sieve box 8 and cooperates with the sliding part 81. A plurality of protrusions 821 are provided on the slide rail 82.
[0043] The driving device 7 drives the sieve box 8, causing the sliding part 81 to reciprocate along the slide rail 82. Specifically, the driving device 7 includes a pneumatic cylinder mounted on the outside of the screening cylinder 6, and the piston rod of the pneumatic cylinder is used to drive the sieve box 8.
[0044] The first screening mechanism is further provided with a second screening mechanism below,
[0045] The second screening mechanism comprises a sieve plate 10 and a cam 100.
[0046] The sieve plate 10 is slidingly connected to the side wall of the screening cylinder 6.
[0047] The cam 100 is used for supporting the sieve plate 10, and the cam 100 rotates under the driving of a driving motor and drives the sieve plate 10 to vibrate up and down.
[0048] The first screening mechanism and the second screening mechanism are provided with a flow guide 9, which is used for guiding the radix sophorae flavescentis screened by the upper sieve box 8 to the lower sieve plate 10.
[0049] The driving device 7 further comprises a reset elastic member 83 located between the sieve box 8 and the screening cylinder 6, and the elastic force of the reset elastic member 83 is used for pushing the sieve box 8 to move towards the direction close to the piston rod.

[0051] The specific screening principle is as follows: the radix sophorae flavescentis falling from the feeding box 5 enters the sieve box 8 in the screening cylinder 6, the driving device 7 drives the sieve box 8 through the pneumatic cylinder installed outside the screening cylinder 6, the piston rod of the pneumatic cylinder is used for driving the sieve box 8; the reciprocating movement of the piston rod of the pneumatic cylinder drives the sliding part 81 to move back and forth along the slide rail 82, and the sliding part 81 cooperates with the protrusion 821 to generate the vibration of the sieve box 8; the vibration amount at each position of the sieve box 8 remains consistent, avoiding the problem that the vibration amount far from the driving mechanism end of the existing vibrating screening mechanism is small, causing the sieve box 8 to be blocked.
[0052] The elastic force of the reset elastic member 83 is used for pushing the sieve box 8 to move towards the direction close to the piston rod. In this way, when the piston rod of the pneumatic cylinder is extended, it pushes the sieve box 8 to move in the first direction, and the reset elastic member 83 is in the energy storage state; when the piston rod is retracted, the elastic force of the reset elastic member 83 pushes the sieve box 8 to move in the second direction, and the first direction and the second direction are oppositely arranged. The sieve box 8, the reset elastic member 83 and the end of the piston rod of the pneumatic cylinder are all connected through a push plate. Since the sieve box 8 does not need to be connected with other components, when the screening is completed, the sieve box 8 can be directly taken out by opening the door body 60.
