Description

Technical Field

[0001] This utility model relates to the field of pesticide formulation technology, and in particular to a detachable multi-layer pesticide slow-release rack for registration testing. Background Technology

[0002] In pesticide development, the application of controlled-release technology is crucial. It primarily regulates the release rate of pesticide active ingredients through physical encapsulation, chemical bonding, or carrier loading to address the rapid degradation of traditional pesticides due to photolysis, hydrolysis, or volatilization. Controlled-release systems can extend pesticide efficacy to weeks or even months, significantly reducing the frequency of application. Simultaneously, they mitigate the risk of phytotoxicity by reducing the initial burst release effect and minimize pesticide runoff pollution.

[0003] Existing pesticide slow-release racks mostly use fixed support structures, which cannot be flexibly adjusted according to the actual height requirements of the slow-release cups. This results in instability when placing slow-release cups of different sizes, either due to the rack being too high or too low, affecting the slow-release effect. Due to the lack of adjustable load-bearing mechanisms, the racks are difficult to match the various diameters and heights of slow-release cups available on the market. When multiple types of slow-release cups need to be placed simultaneously, multiple sets of racks of different sizes are often required, increasing operating costs and reducing operational efficiency. In terms of disassembly and maintenance, existing racks mostly use permanent connections such as welding or bolting, making daily cleaning, component replacement, and transportation / storage extremely inconvenient.

[0004] To address the aforementioned problems, this utility model proposes a detachable multi-layer pesticide slow-release holder for registration testing. Utility Model Content

[0020] Please see Figure 1-4 This utility model provides a technical solution: a detachable multi-layer pesticide slow-release rack for registration tests, including a rack body 1, with multiple placement plates 2 inside the rack body 1, guide grooves 3 on both sides of the inner wall of the rack body 1, and sliders 4 integrally formed at both ends of the placement plates 2, with the sliders 4 being limited and slidably disposed in the guide grooves 3.

[0021] Specifically, circular grooves 7 are provided at both ends of the placement plate 2 corresponding to the positions of the sliders 4. Limiting rods 8 are slidably installed inside the circular grooves 7. Multiple limiting holes 9 are evenly provided longitudinally inside the guide grooves 3. The limiting rods 8 are inserted into the limiting holes 9. A return spring 10 is fixedly connected to one end of the limiting rod 8 away from the limiting hole 9. The other end of the return spring 10 is fixedly connected to the inside of the circular groove 7. Connecting grooves 11 are provided on both sides of the bottom end of the placement plate 2. A lever 12 is slidably installed inside the connecting groove 11. The lever 12 is fixedly connected to the limiting rod 8.

[0022] Furthermore, loading and unloading slots 5 are provided on both sides of the inner wall of the frame 1 for removing the placement plate 2. The loading and unloading slots 5 are internally connected to the guide slot 3, and the slider 4 is transitionally fitted with the loading and unloading slots 5, realizing the quick assembly and disassembly of the placement plate 2, which facilitates the cleaning, maintenance and component replacement of the equipment.

[0023] Multiple placement positions 6 are evenly spaced on the upper surface of the placement plate 2. Each placement position 6 is equipped with a spiral anti-slip pad 15 to prevent the slow-release cup from accidentally sliding or tipping over during the test.

[0024] In this embodiment of the invention: a baffle 16 is fixedly installed on the front side of each placement plate 2, and a label holder 13 is fixedly installed on each baffle 16 at the position corresponding to the placement position 6, for registering experimental data and labels. This provides a standardized location for recording experimental data, ensuring that the experiment number and data are clearly traceable.

[0025] In this embodiment of the invention, multiple heating lamps 14 are equidistantly embedded inside the frame 1. These heating lamps 14 are powered by an external power source and are used to regulate the temperature of the slow-release environment. This achieves precise control of the slow-release environment temperature, meeting the temperature requirements under different experimental conditions.

[0026] Working principle: When the height of the placement plate 2 needs to be adjusted, the operator should simultaneously pinch the levers 12 on both sides of the bottom of the placement plate 2 with their thumbs and forefingers, and apply uniform pressure inward along the guide track of the connecting groove 11. At this time, the levers 12 drive the limiting rod 8 to move horizontally within the circular groove 7, causing the return spring 10 to undergo elastic compression deformation. When the limiting rod 8 is completely released from the constraint of the current limiting hole 9, the slider 4 is released from the locked state. At this time, the operator can smoothly slide the placement plate 2 up and down along the vertical track of the guide groove 3 to the target height. During the sliding process, the cooperation between the guide groove 3 and the slider 4 ensures the straightness and stability of the movement trajectory. When the placement plate 2 reaches the predetermined position, the operator slowly releases the levers 12. The restoring force of the return spring 10 pushes the limiting rod 8 to accurately insert into the limiting hole 9 of the corresponding height. At this time, a clear "click" locking sound can be heard, indicating that the height adjustment is complete.

[0027] The adjustable mechanism allows the placement plate 2 to be positioned at multiple height levels within the frame 1, accommodating the placement needs of different sized slow-release cups. When the placement plate 2 needs to be disassembled for cleaning or replacement, first adjust it to the lowest position, then continue applying downward pressure to fully engage the slider 4 in the transition area of ​​the loading / unloading slot 5. At this point, the constraint between the slider 4 and the guide groove 3 is released, and the operator can smoothly pull the placement plate 2 outward at a 15-degree angle. The entire disassembly process can be completed without any tools. For reverse installation, simply align the slider 4 with the entrance of the loading / unloading slot 5 and push it in along the reverse trajectory of disassembly. Once the slider 4 is fully engaged in the guide groove 3, it will automatically reset. This ingenious design ensures structural stability during use while also providing convenient quick disassembly and assembly.

[0028] The placement positions 6 evenly distributed on the placement plate 2, together with the spiral texture of the anti-slip pad 15, can stably support various standard slow-release cups with diameters ranging from 50 to 100 mm. The label stand 13 on the baffle 16 provides a standardized marking area for recording experimental data, ensuring the traceability of the experimental process.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
