Description

Technical Field

[0001] This utility model relates to the field of cotton breeding technology, and more specifically, it relates to an efficient seed collection device for cotton breeding. Background Technology

[0002] In the field of cotton breeding, seed collection and classification are key links to ensure breeding quality. Since different varieties of cotton seeds differ in size, shape and other aspects, it is necessary to frequently change the screening components according to different screening requirements. This requires the collection device to have convenient replacement function and efficient classification ability to improve the efficiency of breeding work.

[0003] However, the seed collection devices commonly available on the market have obvious shortcomings. Most traditional screening structures adopt a fixed installation method, and multiple fasteners need to be disassembled when replacing the screen, which is cumbersome and time-consuming. At the same time, the disassembly and assembly structure of the screening components is complicated, and the connection between parts is not flexible enough, which can easily cause damage or loss of parts during frequent replacement.

A quick-installation mechanism is provided on the filter plate 3. The quick-installation mechanism includes an insertion rod 8, a slot 9, a fixing sleeve 10, a snap-fit ​​piece 11, and a quick-release mechanism. The insertion rod 8 is inserted into the placement box 2 and the filter plate 3. Multiple sets of slots 9 are distributed on the outer wall of the insertion rod 8. The fixing sleeve 10 is inserted into the top of the insertion rod 8. Multiple sets of snap-fit ​​pieces 11 are distributed on the inner side of the fixing sleeve 10. An aggregation hopper 12 is installed inside the mounting frame 1.

[0030] The quick-release mechanism includes a movable sleeve 13, a pulling frame 14, a sliding sleeve 15, and a quick-release sleeve 16. The movable sleeve 13 slides on the outside of the fixed sleeve 10, the pulling frame 14 is installed on the inside of the movable sleeve 13, the sliding sleeve 15 slides inside the fixed sleeve 10, and the quick-release sleeve 16 is located on the top surface of the sliding sleeve 15 and is fixedly connected to the pulling frame 14. The movable sleeve 13 drives the pulling frame 14, which in turn drives the quick-release sleeve 16 and the sliding sleeve 15 to form a linkage mechanism, thereby achieving quick disassembly.

[0031] The fixed sleeve 10 is provided with a slide rod 17. Multiple slide rods 17 are provided and are slidably connected to the slide sleeve 15. The slide rod 17 provides guidance for the slide sleeve 15 to ensure the accuracy of its movement trajectory.

[0032] A compression spring 18 is provided between the top surface of the sliding sleeve 15 and the inner side of the fixed sleeve 10. Multiple sets of compression springs 18 are provided. When the compression spring 18 is compressed, it stores elastic potential energy. When it is released, it can make the sliding sleeve 15 automatically return to its original position.

[0037] In this embodiment, seeds are placed in the placement box 2. The motor 5 is started and transmits power to the connecting block 6 through the reducer 4. The connecting block 6 drives the connecting rod 7, which in turn drives the placement box 2 to move repeatedly. The placement box 2 slides along the slide rail 26 via multiple sets of sliders 25. The seeds are sieved through the filter plate 3 by the repeated shaking of the placement box 2. Seeds of different sizes are sieved and collected. The sieved seeds fall into the external collection box through the collection hopper. When it is necessary to disassemble the filter plate 3, the movable sleeve 13 pulls the quick-release sleeve 16 through the pull frame 14. The quick-release sleeve 16 slides along multiple sets of slide rods 17 via the sliding sleeve 15 and compresses the compression spring 18. The top of the quick-release sleeve 16 pushes multiple sets of snap-fit ​​pieces 11 to disengage it from the slot 9.

Multiple sets of positioning blocks 20 are used for positioning and insertion into the positioning groove 19. Multiple sets of snap-fit ​​pieces 11 are used to snap and fix the insertion rod 8 in the slot 9, thereby completing the installation of the filter plate 3.

[0039] In summary, when the entire device is in use or running: seeds are placed in the placement box 2, the motor 5 is started and the power is transmitted to the connecting block 6 through the reducer 4, the connecting block 6 drives the connecting rod 7, the connecting rod 7 drives the placement box 2 to move repeatedly, the placement box 2 slides along the slide rail 26 through multiple sets of sliders 25, the seeds are repeatedly shaken by the placement box 2 and screened through the filter plate 3, and seeds of different sizes are screened and collected. The screened seeds fall into the external collection box through the collection hopper. When it is necessary to disassemble the filter plate 3, the movable sleeve 13 pulls the quick release sleeve 16 to slide through the pull frame 14, the quick release sleeve 16 slides along multiple sets of slide rods 17 through the sliding sleeve 15 and compresses the compression spring 18, the top of the quick release sleeve 16 pushes multiple sets of snap-fit ​​pieces 11 to disengage it from the slot 9, and then pushes the insertion rod 8 to separate from the fixed sleeve 10 through multiple push springs 22. The filter plate 3 is disassembled in sequence.

[0040] When the filter plate 3 needs to be installed, insert the rod 8 into the box 2 and the filter plate 3, then insert the fixing sleeve 10 into the rod 8, and use multiple sets of positioning blocks 20 to position and insert into the positioning groove 19.
