[0021] See also Figures 1 to 4 A precision sowing and screening device for Codonopsis pilosula seeds includes a device body 1, two screening structures 3 distributed up and down are installed inside the device body 1, the screening structure 3 includes a mounting frame 301, a mounting groove 305 is opened at the bottom edge of the mounting frame 301, a screening frame 4 located on the upper end surface of the mounting groove 305 is installed inside the mounting frame 301, the screening structure 3 also includes two slides 302 fixedly connected to the left and right inner walls of the device body 1, the two slides 302 are both slidably connected to the mounting frame 301, the outer walls of the two slides 302 are both installed with springs 303 located on the outside of the mounting frame 301, and the outer wall of the mounting frame 301 is installed with a vibration motor 304;

[0022] A material guide cavity 2 located above the screening frame 4 is installed at the top of the interior of the equipment body 1 . The lower end surface of the material guide cavity 2 is an open structure. A plurality of staggered dispersion plates 201 are fixedly connected to the interior of the material guide cavity 2 .

[0023] In this embodiment, the codonopsis seeds are put into the guide cavity 2, and then the staggered dispersion plates 201 collide with the codonopsis seeds entering the guide cavity 2, so that the codonopsis seeds are dispersed and fall to the upper end surface of the upper screening frame 4, thereby preventing the codonopsis seeds from falling in piles and affecting the screening effect;

[0024] Secondly, the screening structure 3 is used to screen the Codonopsis pilosula seeds. Specifically, the controller 7 controls the two vibration motors 304 to work synchronously, prompting the two mounting frames 301 to drive the screening frame 4 to slide left and right on the outer wall of the slide 302 for screening. And because the lower screening frame 4 and the mounting frame 301 are larger than the upper screening frame 4 and the mounting frame 301, the seeds in the upper screening frame 4 can be prevented from falling outside during the seed screening process. As the mounting frame 301 and the screening frame 4 vibrate and screen, the spring 303 is stretched or compressed by force, thereby allowing the impurities in the Codonopsis pilosula seeds to remain in the upper screening frame 4, while the full and qualified fine seeds remain in the lower screening frame 4, and the unqualified seeds can fall into the collection box 5 for collection. After the screening is completed, the controller 7 can control the mutually attracted electromagnets 306 to cut off the power, thereby facilitating the removal of the screening frame 4 from the mounting frame 301, thereby achieving the effect of facilitating the removal and processing of the seeds and impurities remaining in the screening frame 4.

[0025] As a technical optimization solution of the present invention, the upper end surface of the installation groove 305 and the lower end surface of the screening frame 4 are installed with electromagnets 306 that attract each other.

[0026] In this embodiment, the electromagnets 306 on the upper end surface of the mounting groove 305 and the lower end surface of the screening frame 4 are attracted to each other, thereby fixing the mounting frame 301 and the screening frame 4.

[0027] As a technical optimization solution of the present invention, the mesh diameter of the upper screening frame 4 is larger than the mesh diameter of the lower screening frame 4 , and two pull rods 401 are fixedly connected to the upper end surface of the screening frame 4 .

[0028] In this embodiment, the mesh diameter of the upper screening frame 4 is larger than the mesh diameter of the lower screening frame 4, so that impurities and smaller unqualified seeds in the Codonopsis seeds can be screened, and the screening frame 4 can be removed from the installation frame 301 by the pull rod 401.

[0029] As a technical optimization solution of the present invention, a collection box 5 is placed at the bottom end of the equipment body 1.

[0030] In this embodiment, the smaller unqualified Codonopsis seeds that are screened can be collected through the collection box 5.

[0031] As a technical optimization solution of the present invention, the upper end surface of the equipment body 1 is installed with a feed port 101 connected to the material guiding cavity 2, and the lower end surface of the equipment body 1 is fixedly connected with a base 6.

[0032] In this embodiment, the codonopsis seeds are put into the equipment body 1 for screening through the feed port 101, and the equipment body 1 can be supported by the base 6.

[0033] As a technical optimization solution of the present invention, a box door is installed on the outer wall of the equipment body 1 , and a controller 7 is installed on the outer wall of the equipment body 1 . The electromagnet 306 and the vibration motor 304 are both electrically connected to the controller 7 .

[0034] In this embodiment, the interior of the device body 1 can be maintained by opening the box door, and the electromagnet 306 and the vibration motor 304 can be controlled to work by the controller 7.

[0035] Working principle: First, connect the device body 1 to the external power supply, then place the screening frame 4 in the installation slot 305, and at the same time, make the controller 7 control the electromagnet 306 to energize and attract, fix the installation frame 301 and the screening frame 4, and then put the codonopsis seeds into the material guide cavity 2 through the feed inlet 101. The staggered dispersion plates 201 collide with the codonopsis seeds entering the material guide cavity 2, causing the codonopsis seeds to disperse and fall to the upper end surface of the upper screening frame 4, thereby preventing the codonopsis seeds from piling up and affecting the screening effect;

[0036] Secondly, the screening structure 3 is used to screen the Codonopsis pilosula seeds. Specifically, the controller 7 controls the two vibration motors 304 to work synchronously, prompting the two mounting frames 301 to drive the screening frame 4 to slide left and right on the outer wall of the slide 302 for screening. And because the lower screening frame 4 and the mounting frame 301 are larger than the upper screening frame 4 and the mounting frame 301, the seeds in the upper screening frame 4 can be prevented from falling outside during the seed screening process. As the mounting frame 301 and the screening frame 4 vibrate and screen, the spring 303 is stretched or compressed by force, thereby making the impurities in the Codonopsis pilosula seeds stay in the upper screening frame 4, while the full and qualified fine seeds stay in the lower screening frame 4, and the unqualified seeds fall into the collection box 5 for collection. After the screening is completed, the controller 7 can control the mutually attracted electromagnets 306 to cut off the power, and the hand-held pull rod 401 can be taken out of the screening frame 4 from the mounting frame 301, thereby achieving the effect of facilitating the removal and processing of the seeds and impurities that remain in the screening frame 4.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
