During this process, the seeds damaged by insects or shriveled float up due to the buoyancy effect, and then are fished out manually. However, this method has the problem of low efficiency, and the used seed selection liquid is usually directly discharged, resulting in waste and loss of resources. Summary of the Utility Model

[0020] The following describes in detail the specific implementation of the present utility model with reference to specific embodiments.

[0021] As Figures 1 to 5 shown, an oil-tea camellia seed screening device provided by an embodiment of the present utility model, an oil-tea camellia seed screening device, includes a device body 1, and the device body 1 includes support legs 2 fixedly arranged at the lower end of the device body 1 for support, and further includes:

[0024] Stirring unit 13, the stirring unit 13 includes a device cover 14 sleeved on the upper end of the device body 1, a limiting block 141 for limiting is fixedly arranged on the inner side of the device cover 14, a bayonet 142 is fixedly arranged at the position corresponding to the limiting block 141 at the upper end of the device body 1, a motor 15 is fixedly arranged in the middle of the upper end of the device cover 14, a first rotating shaft 16 is movably arranged in the connecting shaft 12, the upper end of the first rotating shaft 16 penetrates through the middle of the device cover 14 and is fixedly connected with the main shaft of the motor 15, a plurality of groups of first stirring claws 161 are fixedly arranged on the outer side of the first rotating shaft 16, a brush 17 is fixedly connected to the bottom of the first stirring claws 161, a second rotating shaft 18 is arranged below the first rotating shaft 16, a connecting head 181 for connection is arranged at the upper end of the second rotating shaft 18, a plurality of groups of second stirring claws 182 are fixedly arranged on the outer side of the second rotating shaft 18, and a connecting sleeve 162 adapted to the connecting head 181 is arranged at the lower end of the first rotating shaft 16 corresponding to the shape of the connecting head 181.

[0025] In an embodiment of the present invention, the movable cover plate 11 provided can block the through hole at the bottom of the second filter cartridge 10, so as to control the passage of camellia seeds, facilitate the screening of camellia seeds, cooperate with the first rotating shaft 16 and the brush 17 provided, and indirectly control the movement of the movable cover plate 11 based on the friction force between the brush 17 and the movable cover plate 11 during rotation. Through the brush 17 provided, the surface of the seeds can also be brushed. By means of the recovery pipe 4 cooperating with the water pump 41, after the seeds are screened and left standing for a period of time, the relatively clear seed selection liquid on the upper layer can be pumped out for recycling, and the seed selection liquid with more impurities mixed in the lower layer is discharged through the sewage outlet 5.

[0026] As Figure 2 shown, as a preferred embodiment of the present invention, small holes with diameters smaller than the diameter of normal camellia seeds are provided on both the side surface and the bottom surface of the first filter cartridge 9, and small holes with diameters smaller than the diameter of normal camellia seeds are provided on the side surface of the second filter cartridge 10.

[0027] In an example of the present invention, the small holes provided on the outer sides of the first filter cartridge 9 and the second filter cartridge 10 can facilitate the passage of the seed selection liquid and screen out the too small seeds.

[0028] As Figure 2 and Figure 4As shown, as a preferred embodiment of the present utility model, the fan plate 111 is provided in a sector structure. Both sides of the fan plate 111 are fixedly provided with retaining grooves 112. At positions corresponding to the retaining grooves 112 on the bottom surface of the second filter cartridge 10, retaining blocks 101 for limiting are fixedly provided. The bottom surface of the second filter cartridge 10 is divided into four regions by the provided fan plate 111. The region of the bottom surface of the second filter cartridge 10 that coincides with the fan plate 111 is provided with holes having a diameter larger than the diameter of normal oil-tea camellia seeds. The remaining regions of the bottom surface of the second filter cartridge 10 and the surface of the fan plate 111 are provided with small holes having a diameter smaller than the diameter of normal oil-tea camellia seeds.

[0029] In an example of the present utility model, through the cooperation of the provided retaining grooves 112 and the retaining blocks 101, it is convenient to control the position of the fan plate 111, and the on-off of the large holes of the second filter cartridge 10 is realized by changing the position of the fan plate 111.

[0030] As Figure 2 and Figure 3 As shown, as a preferred embodiment of the present utility model, a first bearing 19 is fixedly provided at the bottom of the second filter cartridge 10 corresponding to the lower end of the connecting shaft 12. A second bearing 20 is fixedly provided at the upper end of the connecting shaft 12. Above the position corresponding to the second bearing 20 on the outer side of the first rotating shaft 16, a retaining ring 163 integrally formed with the first rotating shaft 16 is fixedly provided. A third bearing 21 is fixedly provided at the bottom of the first filter cartridge 9 corresponding to the lower end of the second rotating shaft 18.

[0031] In an example of the present utility model, through the provided first bearing 19, second bearing 20 and third bearing 21, the rotation of the first rotating shaft 16 and the second rotating shaft 18 is facilitated, and the stirring of the seed selection liquid and seeds in the device by the first stirring claws 161 and the connecting heads 181 is facilitated.

[0032] In an example of the present utility model, during use, first seal the sewage outlet 5 with the sealing plug 6. Load the seeds to be screened into the second filter cylinder 10, pour the seed selection liquid into the device body 1, cover the device cover 14, sleeved the connecting sleeve 162 outside the connecting head 181, and engage the clamping block 141 through the bayonet 142. Start the motor 15 to drive the first rotating shaft 16 and the second rotating shaft 18 to rotate. The rotating first rotating shaft 16 drives the first stirring claw 161 to stir the seeds and the seed selection liquid in the second filter cylinder 10, and drives the brush 17 to rotate. Under the frictional action between the brush 17 and the surface of the fan plate 111, the movable cover plate 11 rotates 90 degrees and is blocked by the stop block 101. At this time, the worm-eaten or shriveled seeds float in the seed selection liquid, and the seeds of normal size and heavier fall from the large holes in the second filter cylinder 10 into the first filter cylinder 9. The over-sized seeds or impurities still remain in the second filter cylinder 10. Then stir the seeds in the first filter cylinder 9 through the provided connecting head 181, and the too-small seeds and impurities fall into the device body 1 through the small holes in the first filter cylinder 9. Subsequently, control the motor 15 to rotate in the reverse direction. Under the frictional action between the brush 17 and the surface of the fan plate 111, the movable cover plate 11 rotates 90 degrees and is blocked by the stop block 101 to block the large holes at the bottom of the second filter cylinder 10. Remove the device cover 14, and then take out the second filter cylinder 10 and the first filter cylinder 9 in sequence. The seeds in the first filter cylinder 9 are the ones that have been screened. After the seed selection liquid is left standing for a period of time, pump out the relatively clear upper layer of the seed selection liquid through the water pump 41 for recycling, and directly discharge the lower layer of the turbid liquid through the sewage outlet 5, and filter out the too-small seeds through the filter cup 7.
