[0026] The utility model will be further described in detail in combination with examples:

[0027] Example 1

[0028] As Figs. 1-6 Indicated, the utility model provides a kind of seed screening equipment for American ginseng planting, including base 1, filter collection box one 2 and filter collection box two 3, the top of filter collection box one 2 is fixedly connected with filter chamber 4, the inner wall of filter chamber 4 is fixedly connected with filter plate 6, the upper surface of filter plate 6 is movably connected with the through roll 9 for the screen hole of it to be dredged, the side of through roll 9 is provided with the material blocking and pushing of material scraping plate 8, and one end of material scraping plate 8 is fixedly connected with the side of guide pull rod 13;

[0029] The outer wall of through roll 9 is fixedly connected with positioning cylinder 18, the inner wall of positioning cylinder 18 is movably connected with through needle 14, the bottom end of through needle 14 is fixedly connected with reset spring 15, and the bottom end of reset spring 15 is fixedly connected with the inner wall bottom of positioning cylinder 18.

[0030] One end of through roll 9 is fixedly connected with gear 12, the outer wall of gear 12 is engaged with rack 10, the inner wall of gear 12 is rotatably connected with guide pull rod 13, and the end, away from gear 12, of guide pull rod 13 is fixedly connected with electric push rod 11 for driving forward.

[0031] The end, away from guide pull rod 13, of electric push rod 11 is fixedly connected to the outer wall of filter collection box one 2 by bolt.

[0032] The bottom surface of material scraping plate 8 is fixedly connected with rubber scraping plate 17, and the bottom surface of rubber scraping plate 17 is slidably connected with the upper surface of filter plate 6.

[0033] Example 2

[0034] As Figs. 1-6 Indicated, on the basis of example 1, the utility model provides a kind of technical scheme: preferably, filter chamber 4 is fixedly connected with the import of filter collection box two 3 by conveying pipe 7, and the inner wall top of conveying pipe 7 is rotatably connected with baffle.

[0035] Both ends of the rack 10 are fixedly connected to the inner wall of the filter chamber 4.

[0036] The material blocking scraper 8 has a groove 16 at one end, and the inner wall of the groove 16 is slidably connected to the outer wall of the rack 10.

[0037] A feeding hopper 5 is fixedly connected to the top of the filter chamber 4. The guide rod 13 has a U-shaped structure and slides through to the outside of the filter chamber 4.

[0038] The top of the filter collection box 2 is equipped with a battery for power supply, or it can be directly powered by an external power source.

[0039] The filter plate 6 is inclined at a certain angle inside the filter chamber 4, and the end of the filter plate 6 that connects with the conveying pipe 7 is connected to the inner wall of the filter chamber 4 at an acute angle, which can be between seventy and eighty degrees.

[0040] The working principle of the seed screening equipment used for American ginseng cultivation will be explained in detail below.

[0041] like Figs. 1-6 As shown, when in use, after the seeds are put into the filter chamber 4 through the feeding hopper 5, they will be filtered through the filter plate 6. Small seeds will fall into the filter collection box 2 for temporary storage, while large seeds will remain on the surface of the filter plate 6.

[0042] When it is necessary to clean the screen holes on the surface of the filter plate 6, the electric push rod 11 is activated. The electric push rod 11 will push the guide rod 13 forward, and the guide rod 13 will pull the gear 12 forward. During the forward movement, the gear 12, under the action of the rack 10, will drive the unblocking roller 9 to rotate and move forward. At the same time, the guide rod 13 will also drive the material blocking scraper 8 to move forward.

[0043] As the unblocking roller 9 rotates forward, the unblocking needles 14 on its outer wall, when engaging with the sieve holes on the filter plate 6, are pushed into the sieve holes by the deformation force of the return spring 15. In non-sieve hole areas, the return spring 15 is compressed and the needles retract into the positioning cylinder 18, without hindering the rolling forward movement of the unblocking roller 9. When the unblocking needles 14 insert into the sieve holes, they push the seeds blocking them out of the sieve holes, resolving the blockage problem. The length of the unblocking needles 14 does not adversely affect the rolling of the unblocking roller 9.

[0044] As the guide rod 13 moves forward, the baffle scraper 8 moves forward simultaneously, and the rubber scraper 17 at its bottom begins to scrape the surface of the filter plate 6. This pushes the seeds towards the position of the conveying pipe 7, and through the conveying pipe 7, the seeds are transported to the filter collection box 3 for secondary filtration. During the process of the baffle scraper 8 pushing the seeds, the baffle in the conveying pipe 7 is forced open towards the conveying pipe 7.

[0045] The rubber scraper 17 is made of rubber material or plastic material, and will not damage the surface of the filter plate 6 during scraping.

[0046] The utility model has been described in detail above, but some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, without departing from the spirit of the utility model, the modifications or improvements are within the scope of the utility model.
