Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This embodiment provides a technical solution: a seed selection device for flowering plants, including an external guide bucket 1 and a screening mechanism 2;

[0026] External guide hopper 1: A support 6 is provided on its outer side, a feed hopper 4 is provided on the upper front side of the external guide hopper 1, a discharge port 5 is provided on the lower rear side of the external guide hopper 1, and a control switch 9 is provided on the left side of the support 6. The input end of the control switch 9 is electrically connected to an external power supply.

[0027] Screening mechanism 2 includes a drive shaft 21, a crank connecting plate 22, a chute 23, a slider 24, a rotating shaft 25, a connecting seat 26, and a sorting hopper 29. The drive shafts 21 are symmetrically rotatably connected to the left and right sides of the outer guide hopper 1. The ends of the four drive shafts 21 facing the outer guide hopper 1 are fixedly connected to the crank connecting plates 22. The sides of the four crank connecting plates 22 are respectively provided with chute 23, and the sliders 24 are slidably connected inside the chute 23. A rotating shaft 25 is fixedly connected between every two laterally adjacent sliders 24. The outer arc surfaces of the two rotating shafts 25 are rotatably connected to the connecting seats 26. The upper ends of the two connecting seats 26 are fixedly connected to the lower surface of a sorting hopper 29. The screening mechanism 2 also includes a lead screw 27 and a torsion valve 28. The lead screws 27 are rotatably connected to the interiors of four sliding grooves 23. The external threaded surfaces of the lead screws 27 are threadedly connected to the middle of the sliders 24 located in the same sliding groove 23. The rear ends of the four lead screws 27 are respectively provided with torsion valves 28. The sorting hopper 29 includes a mother screening hopper 291, a lower drain hole 292, a lower threaded groove 293, a daughter screening hopper 294, an upper drain hole 295, and an upper threaded groove 296. The upper ends of the two connecting seats 26 are fixedly connected to the lower surface of a mother screening hopper 291. The lower side of the mother screening hopper 291 has evenly distributed lower drain holes 292 in the middle. The upper surface of the mother screening hopper 291 has evenly distributed lower threaded grooves 293 on the front and rear sides respectively. The daughter screening hopper 294 is placed on the upper side of the mother screening hopper 291. The upper surface of the 294 has evenly distributed upper drain holes 295 in the middle. The upper surface of the sub-screening hopper 294 has evenly distributed upper threaded grooves 296 on the front and rear sides respectively. The left ends of the two drive shafts 21 on the left side are respectively provided with drive pulleys 3. The lower side of the bracket 6 is provided with a motor 7. The output shaft of the motor 7 is provided with a multi-wedge pulley 8. The two drive pulleys 3 are respectively connected to a multi-wedge pulley 8 through a drive belt. The input end of the motor 7 is electrically connected to the output end of the control switch 9. When the flower seed selection equipment is needed, the sub-screening hopper 294 can be manually picked up and placed inside the mother screening hopper 291. The mother screening hopper 291 can then be moved back and forth. At this time, according to the needs of flower seed production, the lower drain hole 292 and the upper drain hole 295 form a The new sieve hole, the specific size of which can correspond to the required peanut seed size, forms a new sieve hole by combining the lower sieve hole 292 and the upper sieve hole 295. Then, external bolts are screwed into the corresponding lower threaded groove 293 and upper threaded groove 296 to complete the installation of the sorting hopper 29. At this point, according to the peanut seed selection requirements, each pair of horizontally adjacent torsion valves 28 can be turned simultaneously. This causes each pair of horizontally adjacent lead screws 27 to rotate synchronously in both directions, thereby driving each pair of horizontally adjacent sliders 24 to adjust their forward and backward positions simultaneously. This, in turn, adjusts the positions of the two connecting seats 26, thereby adjusting the length of the crank and the height of the subsequent screening. After debugging, the control switch 9 can be adjusted to operate the motor 7.The output shaft of motor 7 rotates, which in turn drives the multi-wedge pulley 8 to rotate. This, in turn, drives the two transmission pulleys 3 to rotate synchronously via the transmission belt. This, in turn, drives the crank connecting plate 22 to rotate around the axis of the transmission shaft 21. This, in turn, drives the sorting bucket 29 to continuously rotate around the center of the outer guide bucket 1 via the rotating shaft 25 and the connecting seat 26, performing continuous up-and-down screening. At this time, the peanut kernels to be sorted are evenly poured into the sorting bucket 29 through the feed hopper 4. The shaking sorting bucket 29 continuously screens the peanut kernels. Unqualified peanut kernels are affected by the screening and fall into the outer guide bucket 1 through the lower drain hole 292 and the upper drain hole 295. Qualified peanut kernels move backward with the sorting bucket 29 and are discharged. At this time, a collection frame is placed at the outlet to collect the qualified peanut kernels. Unqualified peanut kernels are guided by the outer guide bucket 1 and discharged from the discharge port 5, completing the sorting operation.

[0028] The working principle of the peanut seed selection device provided by this utility model is as follows: When the peanut seed selection device is needed, the sub-screening hopper 294 can be manually picked up and placed inside the mother screening hopper 291. The mother screening hopper 291 can then be moved back and forth. At this time, according to the peanut seed selection requirements, the lower leakage hole 292 and the upper leakage hole 295 form a new leakage hole. The specific size of the leakage hole can correspond to the required peanut seed size. After the lower leakage hole 292 and the upper leakage hole 295 form a new leakage hole, the external bolts can be screwed into the corresponding lower threaded groove 293 and upper threaded groove 296 to complete the installation of the sorting hopper 29. At this time, according to the peanut seed selection requirements, each pair of horizontally adjacent torsion valves 28 can be turned simultaneously. At this time, each pair of horizontally adjacent lead screws 27 rotate synchronously in the forward and reverse directions, thereby driving each pair of horizontally adjacent sliders 24 to adjust their forward and backward positions simultaneously, thereby adjusting the position of the two connecting seats 26, thereby adjusting the length of the crank and adjusting the height of the subsequent screening. After debugging, the control switch 9 can be adjusted to operate the motor 7. The output shaft of the motor 7 rotates, which in turn drives the multi-wedge pulley 8 to rotate. This, in turn, drives the two transmission pulleys 3 to rotate synchronously via the transmission belt. This, in turn, drives the crank connecting plate 22 to rotate around the axis of the transmission shaft 21. This, in turn, drives the sorting bucket 29 to continuously rotate around the center of the outer guide bucket 1 via the rotating shaft 25 and the connecting seat 26, continuously performing up and down screening operations. At this time, the peanut kernels to be sorted are evenly poured into the sorting bucket 29 through the feed hopper 4. The shaking sorting bucket 29 continuously screens the peanut kernels. Unqualified peanut kernels will be affected by the screening and fall into the outer guide bucket 1 through the lower drain hole 292 and the upper drain hole 295. At this time, qualified peanut kernels will move backward with the sorting bucket 29 and then be discharged. At this time, a collection frame is placed at the outlet to collect the qualified peanut kernels. Unqualified peanut kernels are guided by the outer guide bucket 1 and then discharged from the discharge port 5, completing the sorting operation.

[0029] It is worth noting that the motor 7 disclosed in the above embodiments can be freely configured according to the actual application scenario. It is recommended that the motor 7 be a YX132M1-6 horizontal three-phase asynchronous motor. The control switch 9 is equipped with a control button corresponding to the motor 7 and used to control its switching.
