Description

Technical Field

[0001] The utility model belongs to the technical field of seed screening, in particular to agricultural seed sorting equipment. Background Art

[0002] Seed sorting machines are important equipment for seed selection, grading, and impurity removal. They play an important role in agricultural production, providing an effective means for seed selection, grading, and impurity removal. They are efficient, precise, and environmentally friendly, improving seed quality and yield while reducing labor and time costs. They are also beneficial to environmental protection and sustainable development.

[0003] There are many types of seed sorting machines, including vibration screening machines, gravity separators, magnetic separators, and graders, which are suitable for seed processing of different types and requirements. Among them, the vibration screening machine separates seeds by the vibration and pore size of the screen.

[0004] The bottom of the vibrating screening machine's feed trough or hopper is too narrow, resulting in uneven material distribution. The feed trough width should be adjusted to ensure uniform feeding, but this part of the traditional screening machine cannot be adjusted in width. The entire screen is not used completely and evenly. After a long time, the center aperture wears more than the sides, which in turn affects the service life or the continued air separation effect. Secondly, the screens in traditional screening machines are mostly fixed structures and cannot be adjusted according to different seed particle sizes. This requires additional purchases, which increases costs, or the screen replacement process is too cumbersome.

[0005] In order to solve the above problems, this application proposes an agricultural seed sorting device. Utility Model Content

The gaps between adjacent guide blocks 54 cooperate with the baffle 53 to discharge materials. In this embodiment, the baffle 53 can block the feeding chamber 51 after rotation, thereby intercepting the seeds.

[0034] Among them, a turning handle 55 located outside the feeding hopper 4 is fixedly provided on one side of the baffle rod 53, and a limiting ring 56 is fixedly provided on the base 1 through a bracket. A fixed extension shaft is provided between the baffle rod 53 and the turning handle 55, and the extension shaft passes through and rotates in the limiting ring 56. In this embodiment, the extension shaft and the bracket form a support between the baffle rod 53 and the turning handle 55, and at the same time provide a matching platform for the limiting ring 56 and the U-shaped limiting rod 58.

[0035] Among them, an arc-shaped movable groove is formed on the inner side of the limiting ring 56, and a number of limiting holes 57 are distributed on the inner circumference of the arc. A U-shaped limiting rod 58 is installed inside the turning handle 55 through a spring.

[0040] A specific application of this embodiment is: Figure 3 The left side is the interception state of the feeding component 5. At this time, the seeds that need to be sorted can be added to the feeding hopper 4, and then the sorting equipment is started to work. The screen box 2 and the screen 3 are driven to reciprocate on the base 1 by the driving member to form a screening action. At this time, the staff holds the turning handle 55 and presses down the U-shaped limit rod 58. The spring at the bottom of the U-shaped limit rod 58 is compressed and disengaged from the limit hole 57. At this time, the baffle rod 53 and the guide block 54 are rotated in the feeding chamber 51 by the turning handle 55. The seeds fall onto the screen 3 from the gap between the guide blocks 54 and the feeding holes 52 and are then sorted. The feeding amount can also be controlled by controlling the angles of the baffle rod 53 and the guide block 54 on the feeding chamber 51;

[0041] Replacing the screen 3: After lifting the locking block 64, move it upward inside the locking box 63 and compress the locking spring 65. At this time, the locking block 64 is disengaged from the upper part of the sealing plate 62. Rotate the locking block 64 outward, pull the screen 3 out of the guide rail 61 inside the screen box 2, insert the screen 3 to be replaced into the screen box 2 along the guide rail 61, and then rotate the sealing plate 62 upward. The locking block 64 locks the sealing plate 62 under the action of the locking spring 65, and the replacement of the screen 3 is completed.
