[0029] In the embodiment, the bracket includes a long bracket 2 on the side of the feeding device 8 on the base 1 and a short bracket 4 arranged at the end of the base 1, the short bracket 4 is hinged to the sorting mechanism 6, the long bracket 2 is provided with an adjustment groove 21 longitudinally distributed along its length direction, and the other connection end of the sorting mechanism 6 away from the hinged end of the short bracket 4 is slidably arranged in the adjustment groove 21.
[0030] In an embodiment, the sorting mechanism 6 further includes two fixed frames 65. Both ends of the two rollers 66 are rotatably connected with sliders 63, and the sliders 63 at both ends are respectively slidably installed in the two fixed frames 65 for adjusting the distance between the two rollers 66.
[0031] In an embodiment, a lead screw penetrating through the slider 63 and driving the slider 63 to slide is further installed in the fixed frame 65. One end of the lead screw passes through the side wall of the fixed frame 65 and is connected with a hand wheel 62 for more conveniently adjusting the distance between the rollers 66 to adapt to the sorting of seeds of different sizes.
[0032] In an embodiment, the driving device 5 includes a motor 51 installed at the end of the sorting mechanism 6 through a connecting plate. The output end of the motor 51 passes through the connecting plate and is installed with a driving wheel 52. A transmission member is detachably sleeved between the driving wheel 52 and the two driven wheels 64.
[0033] In an embodiment, opposite unilateral guide grooves are provided above both of the two rollers 66. A guide groove 67 with a V-shaped cross-section is formed between the two unilateral guide grooves for guiding the movement of seeds on the sorting mechanism 6.
[0034] In an embodiment, one end of the bottom of the guide groove 67 has an opening, and the opening is directly above the channel formed between the two rollers 66.
[0035] In an embodiment, a discharge port 81 is provided on the top side wall of the feeding device 8, and the discharge port 81 is communicated with the bridge 7.
[0036] The working principle of the small and efficient sorting machine for bad and good seeds based on Embodiment 1 is as follows: The seeds are first placed in the feeding device 8. There is a discharge port 81 on the top side wall of the feeding device 8, and this discharge port 81 is connected to the bridge 7. When the feeding device 8 is started and rotates and vibrates through the internal turntable, the seeds flow out from the discharge port 81 and enter the bridge 7. The bridge 7 serves as a transmission channel to transport the seeds from the feeding device 8 to the sorting mechanism 6. The sorting mechanism 6 is inclined. The sorting mechanism 6 is composed of two parallel rollers 66 inside. The distance between the two rollers 66 is adjustable to meet the sorting requirements of different sizes of bean seeds. A channel for the seeds to pass through is formed between the two rollers 66. There is a single-sided guide groove above each of the two rollers 66. A V-shaped guiding groove 67 is formed between the two single-sided guide grooves, which can guide the seeds to move along the setting direction of the guiding groove 67 to ensure that the seeds can smoothly enter between the two rollers 66. One side of the roller 66 near the end of the base 1 is connected with a driven wheel 64, and a motor 51 is provided at the side end of the sorting mechanism 6. The motor 51 drives the two driven wheels 64 to rotate in the same direction through a transmission member, thereby driving the rollers 66 to rotate. During sorting, the distance between the two rollers 66 is adjusted to be equivalent to the average diameter of the seeds to be sorted. When the seeds enter the channel between the rollers 66, due to the rotation of the rollers 66, the seeds are affected by the rotation of one roller 66 and move towards one side of the channel formed between the two rollers 66. When approaching the channel, the seeds will roll outward under the frictional force of the surface of the other roller 66, preventing the seeds from passing through the channel, so that the seeds can only continue to move along the guiding groove 67 towards the bottom side of the inclined end of the sorting mechanism 6. Defective bad seeds will, due to the differences in their physical properties during the rolling process, such as volume defects, lack of plumpness, diameter less than the average value, etc., be unable to fully contact the two side rollers 66. The two side rollers 66 cannot prevent them from falling down. Then, under the action of gravity, the defective bad seeds pass through the channel and fall into the collection box 3 through the funnel 61. A plurality of funnels 61 arranged in parallel are installed at the bottom of the sorting mechanism 6, and the funnels 61 correspond to the positions of the collection boxes 3 arranged in the base 1. The sorted seeds, according to their size, shape and other characteristics, will fall into different funnels 61 and will finally be collected into the corresponding collection boxes 3. Specifically, the seeds that are too small in volume and have a diameter less than the average value will fall into the collection box 3 near the feeding device 8 first because they are not blocked by the channel; while the defective bad seeds will move a certain distance along the inclined direction of the sorting mechanism 6 and fall into a collection box 3 in the middle of the base 1 when they are not affected by the rolling of the two rollers 66 during the movement process; the good-quality seeds will fall into a collection box 3 arranged at the end of the base 1 or stay above the end of the channel formed between the two rollers 66 at the bottom of the inclined direction of the sorting mechanism 6.
[0037] After the first sorting, the seeds collected in the multiple collection boxes 3 can be separately subjected to secondary sorting to obtain the highest-quality seeds.
[0038] The above specific embodiments are only several preferred embodiments of the present utility model. Based on the technical solution of the present utility model and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
