Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural seed processing and testing technology, and in particular to a small seed counting board for grasses. Background Technology
[0002] The miniature grass seed counting board is a plastic tool specifically designed for small-diameter grass seeds such as wheat, rice, and Kentucky bluegrass. It is primarily used for rapid counting and standardized seed placement. Its surface features evenly distributed indentations or holes adapted to small seeds, and the single-seed design prevents overlap. It supports rapid counting manually or with auxiliary instruments, ensuring consistent spacing between each seed. Suitable for seed germination experiments and quality testing, it is lightweight and durable, and its size is compatible with standard germination boxes, facilitating laboratory or field operations. It is a fundamental tool for grass seed research, breeding, and production, especially suitable for the standardized processing of grass seeds with low thousand-seed weight and fine particle size.
[0003] The working principle of the small grass seed counting board is based on physical positioning and spatial adaptation. The board surface has recesses or through holes according to a preset density distribution rule. The hole diameter is slightly larger than the seed diameter. Gravity and friction are used to make individual seeds embed into the holes, avoiding overlap. When counting, the count is quickly counted through visual feedback that "the count is completed when the hole is full". Manual tapping or vibration can help the seeds fall into place, which greatly improves the handling efficiency and accuracy of small seeds.
[0004] In existing technologies, some small grass seed counting boards may have a small number of seeds stuck on the panel during operation, resulting in the actual number being less than the preset value for the well position. This causes statistical deviations in data such as germination rate and thousand-seed weight. Furthermore, stuck seeds are difficult to fall into the culture medium normally, resulting in insufficient sowing sample size or uneven spacing, which affects the consistency of experimental observations. Therefore, a small grass seed counting board is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a small grass seed counting board, which aims to improve the problem that some small grass seed counting boards in the prior art have a small number of seeds stuck on the panel during operation, resulting in the actual number being less than the preset value of the well position when counting, causing statistical deviations in data such as germination rate and thousand-seed weight. In addition, the stuck seeds are difficult to fall into the culture medium normally, resulting in insufficient sowing sample size or uneven spacing, which affects the consistency of experimental observation.

[0031] 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.
[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a small grass seed counting board, including a handle 1. The handle 1 serves as the handheld part of the counting board, providing a comfortable grip for the operator to hold the board and count seeds. It also provides a mounting base and protective space for other internal components. A fixing ring 2 is fixedly connected inside the handle 1, providing stable support and connecting to a spring 3, thus providing a fixed end for the spring 3 and ensuring reliable support for its extension and retraction.
[0033] A spring 3 is fixedly connected to the front of the fixed ring 2. The spring 3 connects the fixed ring 2 and the fixed ring 4, and its main function is to provide elastic force. When subjected to external force, the spring 3 will compress or stretch. After the external force disappears, it can return to its original shape by its own elasticity, driving the connected parts to move. The other end of the spring 3 is fixedly connected to the fixed ring 4, which serves as the fixed connection point of the slide rod 5, transmitting the force of the spring 3 to the slide rod 5. The slide rod 5 is fixedly connected to the inner side of the fixed ring 4. Driven by the fixed ring 4, the slide rod 5 can slide inside the handle 1, transmitting the movement of the fixed ring 4 to the transmission rod 6 through its own sliding, thus playing a role in force transmission.
[0034] A disc 15 is fixedly connected to the front of the slide rod 5, allowing the operator to apply external force and drive the slide rod 5 to move by pushing the disc 15. A transmission rod 6 is fixedly connected to the rear of the slide rod 5, transmitting the movement of the slide rod 5 to the linkage rod 7. The linkage rod 6 slides inside the panel 12 to ensure the accuracy and stability of the movement. Multiple linkage rods 7 are fixedly connected to the rear of the transmission rod 6. The multiple linkage rods 7 move in coordination under the drive of the transmission rod 6. The fixed shaft 8, slider 9, lifting block 10 and other components inside each linkage rod 7 cooperate to realize the lifting control of the lifting block 10 by the linkage rod 7.
[0035] Multiple linkage rods 7 are all fixedly connected to multiple fixed shafts 8. The fixed shafts 8 provide sliding support shafts for the sliders 9. Two sliders 9 are fixedly connected to the outside of the multiple fixed shafts 8. The sliders 9 cooperate with the sliding grooves 13 inside the lifting block 10. By sliding in the sliding grooves 13, the lifting block 10 is driven to move up and down in the square grooves 14 of the panel 12 to achieve the lifting function.
[0036] Lifting blocks 10 are slidably connected to the outer sides of the two sliders 9. A top platform 11 is fixedly connected to the top of the lifting blocks 10. The top platform 11 is the component that directly contacts the seeds. Through the lifting movement of the lifting blocks 10, the top platform 11 can lift the seeds. A panel 12 is slidably connected to the outer side of the top platform 11. The panel 12 provides a frame for the installation and movement of other components. The square groove 14 inside provides a sliding track for the lifting blocks 10 to ensure the accuracy of its movement. An antibacterial component to prevent mold growth is provided on the outer side of the fixing ring 2.
[0037] Reference Figure 1 , Figure 2 , Figure 4 The antibacterial component includes a support layer 16, the inner side of which is fixedly connected to the outer side of the fixing ring 2. The support layer 16 provides a reliable foundation and structural support for the entire antibacterial component, and can evenly distribute the external pressure, preventing the buffer layer 17 and the antibacterial layer 18 from being damaged due to uneven stress. At the same time, it ensures that the antibacterial component remains stable during the operation of the various boards, without displacement or deformation, and maintains the integrity of the internal structure of the various boards.
[0038] A buffer layer 17 is fixedly connected to the outside of the support layer 16, which can absorb the vibration generated during the use of the various boards and the impact force from external collisions. When the operator holds the various boards, hand shaking or accidental collisions will impact the various boards. The buffer layer 17 converts these impact forces into its own internal energy through its own elastic deformation, thereby reducing the impact of vibration and impact on the antibacterial layer 18, extending the service life of the antibacterial layer 18, and also preventing seeds from scattering or affecting the accuracy of counting due to vibration.
[0039] An antibacterial layer 18 is fixedly connected to the outer side of the buffer layer 17. The antibacterial layer 18 is in direct contact with the external environment and its surface is coated with special antibacterial substances. These antibacterial substances can effectively inhibit the growth of mold on the surface of the seed trays by destroying the cell walls of mold, interfering with the metabolism of mold, or inhibiting the reproduction of mold. Neither a humid environment nor residual seed debris can become a breeding ground for mold, thus ensuring that the seed trays are always clean and avoiding the impact of mold growth on the accuracy of seed counting and seed quality, ensuring the smooth progress of seed counting.
[0040] Reference Figures 2 to 4The outer side of the second fixing ring 4 is slidably connected to the inner side of the first fixing ring 2. The outer side of the slide rod 5 is slidably connected to the inside of the handle 1. The rear side of the handle 1 is fixedly connected to the front side of the panel 12. The handle 1 and the panel 12 work together to provide installation space for the internal components. The outer side of the transmission rod 6 is slidably connected to the inside of the panel 12. The outer sides of the multiple fixed shafts 8 are also slidably connected to the inside of the panel 12. The outer side of the linkage rod 7 is slidably connected to the inside of the panel 12, and the outer side of the linkage rod 7 is slidably connected to the inside of the lifting block 10.
[0041] The lifting block 10 has two sliding grooves 13 inside. The outer side of the slider 9 is slidably connected to the inside of the sliding groove 13. The sliding groove 13 cooperates with the slider 9 to restrict the movement trajectory of the slider 9, so that the movement of the slider 9 can be accurately converted into the lifting movement of the lifting block 10. The panel 12 has multiple square grooves 14 inside. The outer side of the lifting block 10 is slidably connected to the inside of the square grooves 14. The square grooves 14 provide space for the lifting block 10 to slide up and down, ensuring that the lifting block 10 remains stable during movement and does not deviate.
[0042] When the operator pushes the disc 15, the disc 15 causes the slide rod 5 to slide backward inside the handle 1. The slide rod 5 pulls the fixed ring 4 to compress the spring 3, and at the same time transmits the force to the transmission rod 6. The transmission rod 6 slides inside the panel 12, driving multiple linkage rods 7 to move. When the linkage rods 7 move, the internal fixed shaft 8 remains relatively fixed, and the slider 9 slides in the sliding groove 13 of the lifting block 10, thereby pushing the lifting block 10 to move upward in the square groove 14 of the panel 12. The top platform 11 at the top of the lifting block 10 rises accordingly, lifting the small grass seeds placed on the panel 12 and preventing the seeds from getting stuck inside the panel 12.
[0043] The support layer 16 is made of polyoxymethylene (POM). During frequent use of various boards, it can withstand various external pressures and impacts, maintaining the stable shape of the antibacterial component and providing a solid and reliable support for the buffer layer 17 and the antibacterial layer 18. Its excellent wear resistance ensures that the support layer 16 is not prone to wear or deformation under long-term contact and friction with other components, guaranteeing the service life of the antibacterial component. Simultaneously, the low water absorption rate of POM prevents it from absorbing moisture and swelling or deforming in humid seed-counting environments, maintaining dimensional accuracy and structural stability.
[0044] The buffer layer 17 is made of microporous polyurethane elastomer. The material contains a large number of uniformly distributed micropores, which allow it to rapidly undergo elastic deformation when the panels are subjected to external impact or vibration, converting mechanical energy into internal energy and effectively absorbing and buffering the impact force. Its excellent flexibility and elastic recovery capability allow it to quickly return to its original shape after being subjected to force, continuously providing buffering and shock absorption, ensuring the stability and reliability of the panels during operation.
[0045] The antibacterial layer 18 is made of antibacterial polybutylene terephthalate (PPT). The nano-silver antibacterial agent added to the material continuously releases silver ions. These silver ions can penetrate the cell membranes of microorganisms such as mold and bind to key substances within the cells, such as proteins and nucleic acids, disrupting their cell structure and physiological functions, thereby effectively inhibiting the growth and reproduction of microorganisms. Simultaneously, the antibacterial PPT has a smooth surface, which makes it difficult for seeds and debris to adhere to the surface of the antibacterial layer 18. After several applications, residues can be easily removed by rinsing with water, reducing the risk of mold growth caused by organic residue.
[0046] Working principle: The operator inserts several plates into the seed pile and moves the seeds by hand to fill the seed slots on the panel 12. Then, the seeds are poured out. If any seeds are stuck in the seed slots, the operator can press the disc 15. The disc 15 receives external force and drives the slide rod 5 to move. The movement of the slide rod 5 causes the fixed ring 4 to move and the spring 3 to undergo elastic deformation and store elastic potential energy. At the same time, the other end of the slide rod 5 drives the transmission rod 6 to move. The movement of the transmission rod 6 drives the multiple linkage rods 7 connected to it to move. The movement of the linkage rods 7 causes the slider 9 to slide in the sliding groove 13. The lifting block 10 receives the power of the slider 9 and slides upward, causing the top platform 11 to push out the seeds stuck in the seed slots. At this time, the operator releases the spring 3, which releases its elastic potential energy and drives a series of components to return to their original positions, which can prevent any seeds from being left in the seed slots and affecting the accuracy of the seed count.
[0047] The antibacterial component achieves structural support, buffer protection, and antibacterial and antifungal functions through the synergistic effect of the support layer 16, the buffer layer 17, and the antibacterial layer 18. Specifically, the support layer 16 of the agricultural seed treatment and testing technology, made of polyoxymethylene, serves as the basic structure. Its high strength, high wear resistance, and low water absorption provide stable mechanical support for the entire antibacterial component, ensuring it is not deformed by external forces during seed counting. The buffer layer 17 of the agricultural seed treatment and testing technology uses microporous polyurethane elastomer. Its unique microporous structure effectively absorbs the impact force generated during operation, reducing wear between components of the seed plate, while also providing shock absorption protection for the internal structure. The outermost antibacterial layer 18 of the agricultural seed treatment and testing technology is made of antibacterial polybutylene terephthalate. Its nano-silver antibacterial agent continuously releases silver ions, destroying the cell structure of mold and other microorganisms, inhibiting their growth and reproduction. Its smooth surface makes it difficult for seeds to adhere, and residues can be easily removed by rinsing with water, preventing mold growth due to organic residue, thereby extending the service life of the seed plate and ensuring a clean and safe seed counting environment.
[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
