[0033] In this embodiment, an opening adapted to the screening box 7 and the storage box 8 is opened on one side of the screening chamber 2. A sliding plate 901 is fixedly installed on one side of the screening box 7. The sliding groove 902 is adapted to the sliding plate 901.

[0034] Specifically, the combination of the sliding groove 902 and the sliding plate 901 can facilitate the preliminary installation of the screening box 7 and the storage box 8;

[0035] In this embodiment, the mounting rod 903 is generally in a "convex" shape. The protruding end of the mounting rod 903 is fixedly installed on one side of the screening chamber 2. An opening adapted to the protruding end of the mounting rod 903 is opened at one end of the positioning block 904. One end of the positioning block 904 is sleeved on the mounting rod 903 and one side of the positioning block 904 is in contact with one end of the sliding plate 901;

[0036] Specifically, the mounting rod 903 can facilitate the rotational installation of the positioning block 904;

[0037] In this embodiment, magnet blocks 905 are embedded at one end of the side of the positioning block 904 that is in contact with the screening chamber 2 and at corresponding positions on both sides of the chute 902. There is magnetic attraction between the magnet blocks 905 on the positioning block 904 and the magnet blocks 905 on the screening chamber 2. Slide plates 901 are provided at both ends of the screening box 7, and the installation structures of the two groups of slide plates 901 are the same;

[0038] Specifically, when the positioning block 904 is in contact with one side of the slide plate 901, it can position the slide plate 901;

[0039] In this embodiment, the storage box 8 and the screening box 7 have the same specifications and installation structures, and the storage box 8 is located below the screening box 7. No sieve holes 17 are provided at the bottom of the storage box 8;

[0040] Specifically, the storage box 8 can store the seeds screened by the screening box 7.

[0041] The working principle and usage process of the present utility model: The screening box 7 is not limited to one group and can be installed according to actual conditions. As long as it is ensured that the sieve holes 17 of several groups of installed screening boxes 7 gradually decrease from top to bottom. Pour the seeds into the threshing chamber 1, and the threshing roller 3 can thresh the seeds. The threshed stalks and seeds will fall onto the sieve mesh 6. The vibration motor 18 vibrates to drive the inner wall of the threshing chamber 1 to shake, and then several groups of rubber balls 16 can be driven to bounce. The bouncing of the rubber balls 16 can improve the shaking effect of the sieve mesh 6, and thus can accelerate the screening effect between the sieve mesh 6 and the stalks and seeds. The screened stalks will be discharged through the slag outlet 5, and the seeds will fall downward into the screening chamber 2. When the seeds pass by one side of the blower 19, the blower 19 can blow the dust mixed in the seeds into the ash storage bag 20;

[0042] The seeds after being dedusted by the blower 19 will fall into the screening box 7. The screening box 7 can screen the seeds. The vibration motor 18 vibrates to drive the inner wall of the screening chamber 2 to shake, and thus can improve the screening effect of the screening box 7. The seeds smaller than the sieve holes 17 of the screening box 7 will fall out of the screening box 7 and into the storage box 8, and the seeds larger than the sieve holes 17 will still remain in the screening box 7, and the screening of the seeds can be completed. Later, rotate each positioning block 904 in turn so that the positioning block 904 is located above the corresponding slide plate 901. And because there is magnetic attraction between the magnet block 905 above the slide plate 901 and the magnet block 905 at one end of the positioning block 904, the positioning block 904 will not rotate randomly. At this time, pull the handle 10 to take out the screening box 7 and the storage box 8, and the seeds screened in the screening box 7 and the storage box 8 can be processed subsequently. Reversing the above operations later can complete the installation of the screening box 7 and the storage box 8, and the disassembly and assembly of the screening box 7 and the storage box 8 are relatively convenient;

[0043] When the screen 6 needs to be cleaned separately in the later stage, remove the screws used to fix the sealing plate 11, move the sealing plate 11 outwards so that the sealing plate 11 is separated from the handle 13, and pull the handle 13 to take out the screen 6 from the threshing chamber 1, then the screen 6 can be cleaned. Reverse the above operations to complete the installation of the screen 6. The disassembly and assembly of the screen 6 are relatively convenient, which can facilitate the separate cleaning of the screen 6 in the later stage.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
