Description

Technical Field

[0001] This utility model relates to the field of rice seed selection technology, and more specifically, to a rice seed selection device for agricultural production. Background Technology

[0002] Rice seeds are the propagation material used for rice cultivation. Their quality directly affects the yield, quality, and disease resistance of rice. Seed selection, as a key preliminary step in rice cultivation, aims to remove shriveled, insect-infested, damaged, and impurity-laden seeds, retaining plump, healthy, and high-quality seeds. This lays the foundation for efficient rice cultivation and a bumper harvest. Traditional rice seed selection methods include manual screening and water selection. Manual screening is inefficient, labor-intensive, and easily affected by subjective factors. While water selection can separate some unqualified seeds, it suffers from water waste and poor screening effect for fine impurities. In addition, there is also wind selection.

[0003] A search revealed a Chinese patent application with patent number CN202420721595.9, which discloses a rice seed selection device, including a box body. A hopper is embedded in the top of the box body, and a through hole is opened on one side of the hopper above the box body. A baffle is slidably connected inside the through hole. A base is connected to the right side wall of the box body, and a blower is connected above the base.

[0004] Although the aforementioned patent describes a method that involves placing rice seeds into a hopper, removing a baffle, and simultaneously turning on a blower to blow away empty and shriveled seeds, allowing them to fall along the partition into the first collection box, and ensuring that plump seeds fall into the second frame, this method reduces manual labor and avoids the influence of unstable external wind forces. Subsequently, a vibrating motor is used to vibrate and screen the seeds in the second frame, facilitating the rapid selection of plump seeds and further improving seed selection efficiency. However, the following shortcomings still exist in its application: 1. Uneven wind distribution leads to unstable screening results; 2. Vibration screening requires a vibrating motor, adding an extra power source, resulting in higher energy consumption and insufficient resource utilization.

[0005] Therefore, there is an urgent need for a rice seed selection device for agricultural production to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a rice seed selection device for agricultural production to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] An agricultural rice seed selection device includes a box, a hopper fixedly connected to the top wall of the box, a fixing plate fixedly connected to the inner wall of the box, symmetrically distributed casters fixedly connected to the outer wall of the box, and a collection box B slidably connected to the inner wall of the box. The device also includes:

[0009] A blowing and screening assembly includes a blower fixedly connected to the top wall of a fixed plate, an air collection box fixedly connected to the air outlet of the blower, a partition fixedly connected to the outer wall of the air collection box and the partition fixedly connected to the box body, a central air guide block fixedly connected to the inner wall of the air collection box, a top air guide block fixedly connected to the inner wall of the air collection box, a bottom air guide block fixedly connected to the inner wall of the air collection box, and a material guide block fixedly connected to the inner wall of the air collection box.

[0010] A linkage screening component is installed on the outer wall of the air collection box, and the linkage screening component cooperates with the air blowing screening component.

[0011] As a preferred technical solution of this application, the linkage screening component includes an air distribution duct fixedly connected to the outer wall of the box, a rotating cylinder rotatably connected to the inner wall of the air distribution duct, symmetrically distributed air scoops fixedly connected to the outer wall of the rotating cylinder, a rotating plate fixedly connected to the outer wall of the rotating cylinder, a linkage plate A rotatably connected to the outer wall of the rotating plate, a linkage plate B rotatably connected to the end of the linkage plate A away from the rotating plate, and a frame rotatably connected to the outer wall of the linkage plate B.

[0012] As a preferred technical solution of this application, the outer wall of the frame is fixedly connected with symmetrically distributed strong springs, and the end of the strong spring away from the frame is fixedly connected to a fixing box, and the fixing box is fixedly connected to the box body. The outer wall of the frame is clamped with a screen.

[0013] As a preferred technical solution of this application, a door A is rotatably connected to the outer wall of the box, and a door B is also rotatably connected to the outer wall of the box.

[0014] As a preferred technical solution of this application, a collection box A is slidably connected to the outer wall of the fixed box, and handles are fixedly connected to the outer walls of the collection box A, the box door A, and the box door B.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] 1. By coordinating the central, top, and bottom air guide blocks within the air collection box, a single air source is cleverly divided into multiple channels, forming a uniform and stable airflow distribution. This ensures that each seed receives balanced airflow during the screening process, preventing insufficient screening or mis-screening of some seeds due to uneven airflow. This effectively improves the quality and stability of the airflow screening process. Simultaneously, the guide blocks extend the seed feeding time and disrupt the seed's falling trajectory, allowing the seeds more time to come into contact with the airflow, thus improving impurity separation. This ensures that each seed is fully screened, further enhancing the overall screening effect and solving the problem of unstable screening results caused by uneven airflow distribution in existing technologies.

[0018] 2. By fully utilizing the excess wind energy generated during the air-blowing screening process through the set linkage screening components, the wind energy is converted into kinetic energy through the air scoop to drive the rotating drum and subsequent linkage structure for vibration screening. There is no need to equip additional power devices such as motors, which reduces the energy consumption of the equipment. This not only saves energy costs but also conforms to the concept of green and environmentally friendly agricultural production. It solves the problem that existing technologies require vibration motors for vibration screening, resulting in additional power sources, higher energy consumption, and insufficient resource utilization.

It also includes:

[0028] The blowing and screening assembly includes a blower 9 fixedly connected to the top wall of the fixed plate 8. An air collection box 11 is fixedly connected to the air outlet of the blower 9. A partition 10 is fixedly connected to the outer wall of the air collection box 11 and is fixedly connected to the box body 1. A central air guide block 12 is fixedly connected to the inner wall of the air collection box 11. A top air guide block 13 is also fixedly connected to the inner wall of the air collection box 11. A bottom air guide block 14 is also fixedly connected to the inner wall of the air collection box 11. A material guide block 15 is also fixedly connected to the inner wall of the air collection box 11. The airflow generated by the blower 9 enters the air collection box 11. The central air guide block 12, the top air guide block 13 and the bottom air guide block 14 divide the airflow into multiple channels to form a uniformly distributed wind force. The material guide block 15 causes the seeds to fall slowly and disrupts their trajectory, prolonging the contact time with the airflow. Light impurities are blown to the top of the box body 1 and discharged.

[0029] The linkage screening component is installed on the outer wall of the air collection box 11, and the linkage screening component cooperates with the air blowing screening component.

[0030] like Figure 4-5As shown, in a preferred embodiment, based on the above method, the linkage screening component further includes an air distribution duct 16 fixedly connected to the outer wall of the housing 1, a rotating cylinder 17 rotatably connected to the inner wall of the air distribution duct 16, symmetrically distributed air scoops 19 fixedly connected to the outer wall of the rotating cylinder 17, a rotating plate 18 fixedly connected to the outer wall of the rotating cylinder 17, a linkage plate A20 rotatably connected to the outer wall of the rotating plate 18, a linkage plate B21 rotatably connected to the end of the linkage plate A20 away from the rotating plate 18, and a frame 22 rotatably connected to the outer wall of the linkage plate B21. Part of the airflow drives the air scoops 19 through the air distribution duct 16, causing the rotating cylinder 17 to rotate. The rotating cylinder 17 drives the rotating plate 18, and the frame 22 reciprocates through the linkage plate A20 and the linkage plate B21.

[0031] like Figure 5 As shown, in a preferred embodiment, based on the above method, the frame 22 is further provided with symmetrically distributed strong springs 23 fixedly connected to the outer wall. The end of the strong spring 23 away from the frame 22 is fixedly connected to a fixed box 24, and the fixed box 24 is fixedly connected to the box body 1. A screen 2 is snapped onto the outer wall of the frame 22. The frame 22 drives the screen 2 to vibrate, screening out plump seeds that fall into the collection box B26, and separating impurities and unplump seeds.

[0032] like Figure 1 As shown, in a preferred embodiment, based on the above method, the outer wall of the box 1 is rotatably connected to a door A4, and the outer wall of the box 1 is also rotatably connected to a door B5. By opening door A4 and door B5, the collection box A25 and collection box B26 can be taken out through handle 7.

[0033] like Figure 1-2 As shown, in a preferred embodiment, based on the above method, a collection box A25 is slidably connected to the outer wall of the fixed box 24. The outer walls of the collection box A25, the box door A4, and the box door B5 are all fixedly connected to handles 7, and the collection box A25 and the collection box B26 can be taken out through the handles 7.

[0034] Specifically, when using this rice seed selection device for agricultural production: rice seeds enter the housing 1 from the hopper 6. The airflow generated by the blower 9 enters the air collection box 11. The central air guide block 12, the top air guide block 13, and the bottom air guide block 14 divide the airflow into multiple channels, forming a uniformly distributed wind force. The guide block 15 causes the seeds to fall slowly and disrupts their trajectory, prolonging the contact time with the airflow. Light impurities are blown to the top of the housing 1 and discharged. Part of the airflow drives the air scoop 19 through the air distribution pipe 16, causing the rotating drum 17 to rotate. The rotating drum 17 drives the rotating plate 18, which in turn causes the frame 22 to vibrate back and forth through the linkage plate A20 and linkage plate B21. The frame 22 drives the screen 2 to vibrate, screening out plump seeds that fall into the collection box B26. Impurities and unplump seeds are separated. The housing door A4 and housing door B5 are opened, and the collection box A25 and collection box B26 are taken out through the handle 7.
