Description

Technical Field

[0001] The utility model relates to the technical field of seed coating detection and fixing devices, in particular to an extraction and fixing device used for seed coating drug detection. Background Art

[0002] Grain and vegetable seeds are often treated with seed coating, which coats the surface with pesticides and related adjuvants to control seedling diseases and underground pests. However, the production technology of different manufacturers varies considerably. Some manufacturers produce seed coatings with inconsistent pesticide content, resulting in poor pest control effectiveness and even the risk of crop damage. To strengthen the quality control and supervision of seed coating pesticides, it is necessary to measure the pesticide content in the coated seeds, including whether it is the declared active ingredient and its mass fraction.

[0003] Currently, there are no pretreatment devices specifically designed for testing seed coatings. When testing is required, plastic ziplock bags are typically used to simulate the coating process, and conventional extraction equipment used in analytical experiments is used to conduct the extraction process. However, these existing devices fail to take into account the specific characteristics of seed coatings, resulting in significant additive losses during simulated additive testing. Furthermore, plastic ziplock bags cannot be stably placed in conventional extraction equipment, making it easy for the sample to be spilled during the extraction process, resulting in losses and contamination.

The extraction component is embedded in the fixing groove and fixed by a pushing component.

[0007] The utility model places a simulated sample in an extraction component, and fixes the extraction component to the support plate of the support frame through a pushing component, and then places the device in a conventional extraction device to fix and support the simulated sample in the extraction component during various extraction processes such as vibration extraction, ultrasonic extraction, and immersion extraction, thereby ensuring the stable placement of the simulated sample and preventing the simulated sample from spilling.

[0023] The specific implementation methods of the present invention are described to facilitate technical personnel in this technical field to understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific implementation methods. For ordinary technical personnel in this technical field, as long as various changes are within the spirit and scope of the present invention defined and determined by the attached claims, these changes are obvious, and all utility model creations using the concept of the present invention are protected.

[0024] refer to Figures 1-6 , which is a structural schematic diagram of an extraction and fixing device for seed coating drug detection in this embodiment. Its purpose is to solve the problem that the simulated sample cannot be stably placed in a conventional extraction device during the existing seed coating drug detection process. The specific structure of this embodiment will be explained in detail below.

[0025] An extraction and fixing device for detecting seed coating medication comprises an extraction component 1 and a support and fixing component 2.

[0026] Among them, the extraction component 1 is used to hold simulated samples, which include seeds, coating drugs, film-forming agents and other additives. The seeds, coating drugs and additives are placed in the extraction component 1 and rubbed and shaken to simulate the seed coating, and then the extraction component 1 is supported and fixed on the supporting and fixing component 2.

[0027] Specifically, the supporting and fixing component 2 includes a supporting frame 3, the supporting frame 3 includes a base plate, and support plates 31 are arranged on both sides of the base plate through vertical plates. A plurality of fixing grooves 32 are staggered at intervals on both sides of the support plate 31. The specific number of the fixing grooves 32 can be set according to actual needs. The extraction component 1 is embedded in the fixing groove 32 and fixed by the pushing component 4.

[0028] When in use, the support frame 3 is then placed in a conventional extraction device, and the extraction component 1 is fixed by the support frame 3 to fix the simulated sample in the extraction component 1 during various extraction processes such as vibration extraction, ultrasonic extraction, and immersion extraction, thereby ensuring the stable placement of the simulated sample, avoiding spillage of the simulated sample, and effectively connecting subsequent pre-treatment steps such as purification and concentration.

[0029] Specifically, the extraction component 1 includes an extraction bag 11 for placing a simulated sample. The bag mouth of the extraction bag 11 is provided with a fixed neck 12. The extraction bag 11 is made of soft polypropylene material to facilitate kneading and shaking of seeds, coating drugs and additives in the extraction bag 11 to simulate seed coating. The fixed neck 12 is made of hard polypropylene material to facilitate pushing and fixing. A bottle stopper 13 is inserted on the fixed neck 12, and the extraction bag 11 is closed by the bottle stopper 13; the fixed neck 12 is embedded in the fixing groove 32 and fixed by the pushing component 4.

[0030] Optionally, the bottom of the fixing groove 32 fits with the fixing neck 12 . The bottom of the fixing groove 32 may be circular and fit with the fixing neck 12 so as to engage with the fixing neck 12 .

[0031] Specifically, the pushing assembly 4 includes a pushing rod 41, and slides 42 are arranged on both sides of the pushing rod 41. The slides 42 are embedded in the sliding grooves 33 reserved on the support plate 31; through the cooperation of the slides 42 and the sliding grooves 33, the sliding direction of the pushing rod 41 is restricted to prevent the pushing rod 41 from shaking and dislocating, thereby accurately pushing the fixed neck 12 into the fixing groove 32. At the same time, a fixing hole 43 is opened on the slide 42, and a through hole 34 that matches the fixing hole 43 is opened on the support plate 31. After the pushing rod 41 pushes the fixed neck 12 into the fixing groove 32, the pin 44 passes through the through hole 34 and is inserted into the fixing hole 43, thereby fixing the pushing rod 41, thereby restricting the fixing neck 12 in the fixing groove 32.

[0032] Optionally, a conical portion 45 is provided at the top of the push rod 41, and a limiting groove 14 that fits with the conical portion 45 is opened on the fixed neck 12. The conical portion 45 is embedded in the limiting groove 14. The conical portion 45 is embedded in the limiting groove 14 to further limit the fixed neck 12, further preventing the fixed neck 12 from shaking or jumping, causing the simulated sample in the extraction bag 11 to spill out.

[0033] Optionally, a pull plate 46 is provided at the tail of the push rod 41 , and the pull plate 46 facilitates an operator to push the push rod 41 into the fixing groove 32 .

[0034] Although the specific embodiments of the utility model are described in detail in conjunction with the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Within the scope described by the claims, various modifications and variations that can be made by those skilled in the art without creative work still fall within the scope of protection of this patent.
