DETAILED DESCRIPTION

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] A preferred embodiment of the rapid separation and screening device for hybrid rice seeds provided by this utility model is, for example... Figures 1 to 5 As shown: A rapid separation and screening device for hybrid rice seeds includes a base 1; a shell 2 fixed inside the upper part of the base 1; a feed pipe 3 fixedly extending through the upper left side of the shell 2; a feed sleeve 4 fixedly fitted around the upper part of the feed pipe 3; a partition sleeve 5 fixed inside the left side of the shell 2, the interior of the partition sleeve 5 communicating with the interior of the feed pipe 3; and a drive assembly 6 assembled on the outer wall of the shell 2, which can filter rice seeds of different types and sizes; the drive assembly 6 includes a first motor 601 fixed at the middle of the top of the shell 2; and a rotating rod 602 fixed at the bottom of the first motor 601, which rotatably extends through the top of the shell 2. A circular plate 603 is fixed at the bottom of the rotating rod 602 and is rotatably connected to the housing 2. Four screens 604 are fixedly connected inside the circular plate 603. The first motor 601 is a stepper motor. The first motor 601 stops after rotating 90 degrees. The left side of the rotating shaft 702 rotates through the housing 2, and the right side of the rotating shaft 702 is designed to be non-contact with the rotating rod 602. The four screens 604 are arranged in a ring around the axis of the rotating rod 602. The angle between any two screens 604 is 90 degrees. The density of the four screens 604 increases from small to large in the direction of clockwise rotation of the axis of the rotating rod 602.

[0029] It should be noted that the existing rapid separation and screening devices for hybrid rice seeds still have certain shortcomings in actual use. They cannot perform rapid classification and screening of rice seeds of different types and sizes, which reduces the effectiveness and efficiency of rice seed screening.

[0030] In this embodiment, the operator first pours rice seeds into the partition sleeve 5 through the feed pipe 3 from the feed sleeve 4, so that the screen 604 can screen and filter the rice seeds. In addition, the operator can turn on the first motor 601, which drives the rotating rod 602 to rotate the circular plate 603 by 90 degrees and then stops. This allows the screens 604 of different densities to overlap with the partition sleeve 5 in sequence, improving the efficiency and effectiveness of the screens 604 of different densities to screen the rice seeds of different types from small to large in sequence.

[0031] In a further preferred embodiment of this utility model, a flipping assembly 7 is assembled outside the housing 2. The flipping assembly 7 can vibrate the rice seeds inside the partition 5. The flipping assembly 7 includes a second motor 701 fixedly mounted on the top left side of the housing 2; a rotating shaft 702 rotatably mounted inside the lower end of the partition 5; a pulley 703 fixedly mounted on the outside of the rotating shaft 702 and the output end of the second motor 701; a toothed belt 704 tightly mounted on the outside of the pulley 703, the toothed belt 704 meshing with the teeth of the pulley 703; and several flipping bars 705 fixedly mounted on the outer wall of the rotating shaft 702. A controller 8 is fixedly mounted on the outer wall of the housing 2, and the controller 8 is connected to the first motor 601 and the second motor 701 through wires.

[0032] In this embodiment, the operator can turn on the second motor 701. The second motor 701 controls the toothed belt 704 to rotate in conjunction with the pulley 703, the shaft 702, and the turning bar 705. This causes the turning bar 705 to vibrate the rice seeds at the top of the screen 604, ensuring the smooth passage of the rice seeds through the screen 604.

[0033] Example 2

[0034] Based on Example 1, a preferred embodiment of the rapid separation and screening device for hybrid rice seeds provided by this utility model is as follows: Figures 1 to 5 As shown: A discharge pipe 9 is fixedly inserted through the bottom left side of the housing 2. The axis of the discharge pipe 9 is designed to coincide with the center of the spacer 5. A linkage component is set inside the base 1. The linkage component can rotate synchronously with the circular plate 603. The linkage component includes a mounting plate 10 rotatably set inside the lower end of the base 1; a placement groove 11 integrally set inside the mounting plate 10; a connecting rod 12 fixed to the top of the mounting plate 10. The top of the connecting rod 12 rotatably passes through the bottom of the housing 2, and the top of the connecting rod 12 is fixedly connected to the bottom of the circular plate 603; and a box 13 set inside the placement groove 11. The mounting plate 10 has a circular cross-section when viewed from above. There are four placement grooves 11, and each placement groove 11 corresponds to a screen 604.

[0035] In the embodiment, when the first motor 601 drives the round plate 603 to rotate, the round plate 603 drives the connecting rod 12, the mounting plate 10, the placing groove 11 and the box 13 to rotate synchronously, thereby ensuring the stability of the box 13 in collecting the same type of rice seeds.

[0036] In the further preferred embodiment of the utility model, the mounting plate 10 is externally provided with a limiting assembly, which can prevent the box 13 from being separated from the placing groove 11 due to centrifugal force when the mounting plate 10 drives the box 13 to rotate, the limiting assembly comprises a guide groove 14 integrally arranged inside the mounting plate 10, the number of the guide groove 14 is four, a sliding block 15 is slidingly arranged inside the guide groove 14, a limiting ring 16 is fixedly sleeved outside the sliding block 15, the guide groove 14 and the placing groove 11 are designed to be one-to-one corresponding, a spring 17 is fixedly arranged between the bottom of the sliding block 15 and the guide groove 14, four pedal plates 18 are fixedly arranged on the outer wall of the limiting ring 16, the pedal plates 18 and the placing groove 11 are one-to-one corresponding, four accommodating holes 19 are integrally arranged inside the base 1, and the accommodating holes 19 and the placing groove 11 are designed to be mutually coincident.

[0037] In the embodiment, when the mounting plate 10 drives the box 13 to rotate, the limiting ring 16 can prevent the centrifugal force generated when the box 13 rotates from separating from the placing groove 11, when the device is used, the staff steps on the pedal plate 18, so that the pedal plate 18 drives the sliding plate to move along the direction of the guide groove 14, and the spring 17 is deformed, that is, the top surface of the limiting ring 16 and the bottom surface of the placing groove 11 are mutually flush, then the staff can take out the box 13 from the placing groove 11, and the accommodating holes 19 provide the space for taking out the box 13 from the inside of the base 1.

[0038] In summary, the application can quickly classify and screen different types and sizes of rice seeds, and can separately collect the classified and screened rice seeds, thereby improving the screening effect and efficiency of the rice seeds.
