[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) This agricultural corn seed selection device uses a motor to start the second rotating rod, which drives the first rotating plate to rotate. The first rotating plate drives the sliding block to rotate via a rotating shaft. When the sliding block rotates, it can move up and down and back and forth within the arc frame. At the same time, the arc frame can drive the first connecting frame to move laterally and back and forth. This allows the U-shaped pusher plate connected to the first connecting frame to push the corn in the feeding box intermittently, so that the corn can be quantitatively fed into the selection box. This ensures that the corn enters the selection box at a constant speed and quantity, avoiding the problem of inaccurate selection or inconsistent product quality caused by the fluctuation of the corn during vibration.

[0014] 2) This agricultural corn seed selection device uses a motor to drive one end of the second rotating plate to make a circular motion around the motor output shaft. This causes the wedge block, which is connected to the other end of the second rotating plate via a fixed rod, to move up and down in the slide rail. This, in turn, causes the second connecting frame, which is connected to the fixed rod, to drive the slider to slide up and down in the slide groove and along the surface of the slide rod. Under the elastic action of the spring, the slider quickly returns to its original position when it moves up, thereby causing one end of the multiple screen plates to vibrate. This allows the multiple screen plates to vibrate and screen the corn kernels. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Example 1

[0023] Combination Figures 1-5An agricultural corn seed selection device includes a selection box 1, a feeding box 2, and a feeding hopper 3. The feeding hopper 3 is fixedly mounted on the feeding box 2, and the feeding box 2 is fixedly mounted on the selection box 1. The outlet of the feeding hopper 3 is connected to the feeding box 2, and the outlet of the feeding box 2 is connected to the selection box 1. A support frame 6 is fixedly mounted at the bottom of the selection box 1 and the connecting plate 5. The connecting plate 5 is fixedly mounted on the rear side of the selection box 1. A feeding mechanism 7 is installed inside the feeding box 2, and a selection mechanism 8 is installed inside the selection box 1.

[0024] See Figure 2 , Figure 3 and Figure 5 Furthermore, the feeding mechanism 7 includes a first rotating rod 701 rotatably disposed on the rear side of the material selection box 1 and a second rotating rod 702 rotatably disposed on the rear side of the feeding box 2. A belt drive assembly 703 is provided between the first rotating rod 701 and the second rotating rod 702. A first rotating plate 704 is rotatably sleeved on one end of the second rotating rod 702. A rotating shaft 705 is fixedly disposed on the first rotating plate 704. A sliding block 706 is rotatably connected to the rotating shaft 705. A U-shaped pusher plate 707 is slidably disposed inside the feeding box 2. One end of the U-shaped pusher plate 707 slides through the feeding box 2 and is fixedly connected to a first connecting frame 708. An arc frame 709 is fixedly connected to one end of the first connecting frame 708. The sliding block 706 is slidably disposed inside the arc frame 709. A limit seat 710 is fixedly disposed on the rear side of the feeding box 2. One end of the first connecting frame 708 slides through the limit seat 710.

[0025] Specifically, when the second rotating rod 702 rotates, it drives the first rotating plate 704 to rotate. The first rotating plate 704 drives the sliding block 706 to rotate through the rotating shaft 705. When the sliding block 706 rotates, it can move up and down and back and forth within the arc frame 709. At the same time, the arc frame 709 can drive the first connecting frame 708 to move laterally and back and forth. This allows the U-shaped pusher plate 707 connected to the first connecting frame 708 to push the corn material in the feeding box 2 intermittently, so that the corn material can be quantitatively fed into the selection box 1. This ensures that the corn material enters the selection box 1 at a constant speed and quantity, avoiding the problem of inaccurate selection or inconsistent product quality caused by the fluctuation of the corn material during vibration.

[0026] See Figures 2-5Furthermore, the material selection mechanism 8 includes a motor 801. Cranks 803 are fixedly mounted on the output shaft of the motor 801 and on the first rotating rod 701. A connecting rod 804 is fixedly connected between the two cranks 803. A second rotating plate 805 is rotatably sleeved on the connecting rod 804. A slide rail 807 is fixedly mounted on the rear side of the material selection box 1. A wedge block 808 is slidably mounted inside the slide rail 807. A fixing rod 806 is fixedly mounted on the wedge block 808. The other end of the second rotating plate 805 is rotatably sleeved on the fixing rod 806. A second connecting frame 809 is fixedly mounted on the other end of the fixing rod 806. Three screen plates 810 are installed inside the material selection box 1. One of the screen plates 810... The screen plate 810 is hinged to the inner wall of the material selection box 1. The other end of the screen plate 810 is fixedly equipped with a slider 811. The second connecting frame 809 is fixedly connected to the slider 811. One end of the material selection box 1 is provided with a slide groove 812 that is slidably connected to the slider 811. A slide rod 813 that is slidably connected to the slider 811 is fixedly installed in the slide groove 812. A spring 814 that is fixedly installed between the slider 811 and the slide groove 812 is sleeved on the slide rod 813. The other end of the material selection box 1 is provided with three discharge ports 815. Three guide plates 4 corresponding to the three discharge ports 815 are fixedly installed at the other end of the material selection box 1. A bracket 802 that is fixedly connected to the motor 801 is fixedly installed on the connecting plate 5.

[0027] Specifically, the motor 801 drives one end of the second rotating plate 805 to make a circular motion around the output shaft of the motor 801, so that the wedge block 808, which is connected to the other end of the second rotating plate 805 through the fixed rod 806, can move up and down in the slide rail 807. This allows the second connecting frame 809, which is connected to the fixed rod 806, to drive the slider 811 to slide up and down in the slide groove 812 and along the surface of the slide rod 813. Under the elastic action of the spring 814, the slider 811 quickly returns to its original position when it moves up, so that one end of the multiple screen plates 810 can vibrate, thus enabling the multiple screen plates 810 to vibrate and screen the corn kernels.

[0028] In actual operation, corn is poured into the feeding box 2 through the feeding hopper 3. The motor 801 is started, which causes the first rotating rod 701 to drive the second rotating rod 702 to rotate under the transmission of the belt drive assembly 703. The second rotating rod 702 drives the first rotating plate 704 to rotate. When the first rotating plate 704 rotates, it drives the sliding block 706 to rotate through the rotating shaft 705. When the sliding block 706 rotates, it can move up and down in the arc frame 709. At the same time, the arc frame 709 can drive the first connecting frame 708 to move laterally in the reciprocating motion. This allows the U-shaped pusher plate 707 connected to the first connecting frame 708 to push the corn in the feeding box 2 intermittently, so that the corn can be quantitatively fed into the selection box 1.

[0029] Corn kernels fall onto the screen plate 810 in the material selection box 1. When the motor 801 is working, one end of the second rotating plate 805, which is rotatably sleeved on the connecting rod 804 between the two cranks 803, can make a circular motion with the output shaft of the motor 801 as the center. This causes the wedge block 808, which is connected to the other end of the second rotating plate 805 through the fixed rod 806, to move up and down in the slide rail 807. This causes the second connecting frame 809, which is connected to the fixed rod 806, to drive the slider 811 to slide up and down in the slide groove 812 and along the surface of the slide rod 813. Under the elastic action of the spring 814, the slider 811 quickly returns to its original position when it moves up. This causes one end of the multiple screen plates 810 to vibrate, so that the multiple screen plates 810 can vibrate and screen the corn kernels. Corn kernels of the same size flow to the corresponding discharge port 815 on the corresponding screen plate 810 and are discharged through the corresponding guide plate 4.
