Description
Technical Field
[0001] The utility model relates to the technical field of sample extraction equipment, in particular to a sample extraction equipment for plant quarantine. Background Art
[0002] Plant quarantine is an important measure to prevent the introduction and export of quarantine pests and to ensure the safety of agricultural production, ecological environment and human health. The sample extraction equipment for plant quarantine is a key tool in quarantine work. It can accurately collect plant samples, process and temporarily store the samples, and provide a reliable sample source for subsequent detection and analysis, so as to determine whether the plants carry pests or other abnormal substances.
[0003] Traditional sample extraction equipment is mainly composed of a sampling part, a sample transmission channel, a grinding device, a storage unit and a control part. The sampling part usually has a simple handheld sampling tool or a fixed sampling head to obtain plant samples; the sample transmission channel is mostly a simple pipe or slide to transport the collected samples to the next step; the grinding device is generally a relatively fixed grinding table and grinding parts combination to crush the sample; the storage unit contains some ordinary containers or boxes for storing processed samples; the control part is a relatively basic switch and a simple control knob to operate the operation of each component of the equipment.
[0004] From a structural perspective, traditional sample extraction equipment has the problem of difficult disassembly and assembly of the grinding table, mainly because its connection method mostly adopts welding or a large number of bolts. Welding makes the grinding table and the main body of the equipment form an integral whole, which is difficult to separate; a large number of bolts require more time and tools to disassemble and install, and the bolts are difficult to operate due to rust or wear. This situation makes it extremely inconvenient when the grinding table needs to be cleaned, repaired or replaced, which prolongs the equipment maintenance time and reduces the efficiency of equipment use. At the same time, due to the difficulty of disassembly and assembly, the residual samples on the grinding table cannot be cleaned in time, which is easy to cause cross-contamination of samples, affecting the accuracy of subsequent test results, and when the grinding table fails, it cannot be quickly replaced, delaying the progress of the entire plant quarantine work. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Reference Figure 1-Figure 3 , the utility model provides an embodiment: a sample extraction device for plant quarantine, including a workbench 1, which is the basic operating platform of the entire device, and provides stable support for other components such as a grinding table 2 and a sampling table 12. The upper surface of the workbench 1 is provided with a grinding table 2, and the grinding table 2 is a key component for grinding samples. Its surface material has a certain wear resistance and roughness, and can effectively grind plant samples, etc. The upper surface of the workbench 1 is fixedly connected with a sampling table 12, and the sampling table 12 is an area for collecting plant samples. A disassembly assembly component is provided on the top of the workbench 1, and a pressing assembly is provided on the top of the workbench 1, and the pressing assembly is used to press plant samples;
[0026] The disassembly and assembly components include a collar 8, which cooperates with the plug post 3 to form a locking mechanism. Multiple collars 8 are fixedly connected to the top of the workbench 1, and multiple plug posts 3 are fixedly connected to the side wall of the grinding table 2. The plug posts 3 play a role of connection and positioning in the device. The plug posts 3 are slidably connected inside the collar 8. A slider 5 is slidably connected inside the plug post 3, which slides inside the plug post 3, receives the thrust from the connecting rod 6, and transmits it to the block 7. A spring 4 is arranged inside the plug post 3. When the slider 5 pushes the block 7 into the side platform 9, the tension of the spring 4 can keep the position of the slider 5 stable, thereby indirectly maintaining the engagement state of the block 7 and the side platform 9. One end of the spring 4 is fixedly connected to The side wall of the grinding table 2, the other end of the spring 4 is fixedly connected to the side wall of the slider 5, the side wall of the slider 5 is rotatably connected to multiple connecting rods 6, one end of each connecting rod 6 is rotatably connected to a clamping block 7, the clamping block 7 is a key element for realizing the connection and fixation of components, both sides of the ring 8 are fixedly connected to side platforms 9, the side platform 9, as a part of the device, provides a clamping position and guide for the clamping block 7, each side platform 9 is slidably connected to a slider 2 10, a tension spring 11 is arranged inside the side platform 9, the tension spring 11 is mainly used for the reset operation of the slider 2 10 in the device, one end of the tension spring 11 is fixedly connected to the side wall of the slider 2 10, and the other end of the slider 2 10 is fixedly connected to the inside of the side platform 9.
[0027] Specifically, during use, the grinding table 2 will contact various plant samples, and the residues, juice, etc. of the samples are likely to remain on the surface and inside of the grinding table 2. When the grinding table 2 needs to be cleaned, the operator manually moves the sliders 2 10 located on both sides. After being acted upon by external force, the sliders 2 10 will begin to slide along a specific track inside the side table 9. This sliding action of multiple sliders 2 10 will further generate a thrust effect on the block 7 stuck inside the side table 9. After being acted upon by the thrust, the block 7 will be further stressed and drive the connecting rod 6 connected to its side wall to start rotating. The rotation of the connecting rod 6 will push the slider 1 5, and the slider 1 5 will then slide along a predetermined path inside the plug column 3 under the action of external force. When multiple blocks 7 slip out of the side table 9, the ring 8 that was originally engaged with the plug column 3 loses its grip. The locking relationship is established, and the plug post 3 can be smoothly pulled out from the inside of the ring 8, thereby realizing the disassembly operation of the grinding table 2. When the plug post 3 is re-engaged with the ring 8, the tension of the spring 4 will play a role first, which can ensure that the slider 1 5 has enough force to push the block 7 to make it located in the side table 9 and maintain a stable locking state, thereby preventing the block 7 from accidentally loosening or slipping off. The tension spring 11 can ensure that the slider 2 10 will not cause the block 7 to slip off the side table 9 due to accidental touch during the resetting process. The grinding table 2 can be disassembled quickly and conveniently, and then it can be thoroughly and carefully cleaned to ensure that there is no sample residue on the grinding table 2 and avoid cross contamination, thereby ensuring the accuracy and reliability of subsequent use and providing a clean and pollution-free grinding operation platform for related experiments or production processes.
[0028] Reference Figure 4The pressing assembly includes a connecting platform 13, which is fixedly connected to the top of the workbench 1. An electric push rod 14 is provided inside the connecting platform 13. A turntable 16 is fixedly connected to the side wall of the connecting platform 13. The turntable 16 plays a role in connecting and converting the direction of movement in the device. A straight groove 15 is fixedly connected to the side wall of the connecting platform 13. The straight groove 15 provides a sliding track and guide for a push column 17. A push column 17 is fixedly connected to the output end of the straight groove 15. The push column 17 is slidably connected to the inside of the electric push rod 14. A telescopic rod 19 is rotatably connected inside the turntable 16. The bottom of the telescopic rod 19 is rotatably connected to a connecting wheel 18. The connecting wheel 18 plays a role in connecting and converting the form of movement in the mechanical transmission chain of the device, receiving the thrust of the push column 17 and converting it into the thrust of the telescopic rod 19. Rotational power, the connecting wheel 18 is rotatably connected to one end of the push column 17, the side wall of the connecting platform 13 is fixedly connected with a hanging platform 21, which is a component connecting the glass pressing plate 24 and the sliding shaft 22. It realizes the up and down movement of the glass pressing plate 24 through the vertical sliding of the sliding shaft 22 inside the hanging platform 21. There are multiple sliding shafts 22 slidingly connected inside the hanging platform 21. The sliding shaft 22 slides vertically inside the hanging platform 21 and is one of the key components to realize the up and down movement of the glass pressing plate 24. The top side of the sliding shaft 22 is fixedly connected with a side plate 23, one end of the telescopic rod 19 is rotatably connected with a rotating rod 20, one end of the rotating rod 20 is rotatably connected inside the side plate 23, and the bottom end of the sliding shaft 22 is fixedly connected with a glass pressing plate 24. The glass pressing plate 24 is a component that directly contacts and presses the plant sample. The glass material has the characteristics of transparency, smoothness and flatness, which is convenient for operators to observe the state of the sample during the pressing process.
[0029] Specifically, when faced with a task of pressing plant samples, such as leaves, etc., the relevant personnel start the electric push rod 14. Once the electric push rod 14 is started, it will apply a thrust to the push column 17, causing the push column 17 to first start to slide in the horizontal direction inside the straight groove 15. During the sliding process, the push column 17 will further push the connecting wheel 18 connected to one end thereof. When the position of the connecting wheel 18 is changed due to the push of the push column 17, the connecting wheel 18 will exert a thrust on the telescopic rod 19 on its outer wall, causing the telescopic rod 19 to rotate inside the turntable 16 and gradually change its own inclination angle during the rotation. The change in the angle of the telescopic rod 19 will have a pushing effect on the rotating rod 20 at one end thereof, causing the rotating rod 20 to rotate inside the side plate 23 and to rotate to the rotating rod 20. The side panels 23 are pushed and pulled. After being subjected to the push-pull force of the rotating rod 20, the side panels 23 will further drive the sliding shaft 22 at the bottom to slide in the vertical direction inside the hanging platform 21. This vertical sliding process of the hanging platform 21 will drive the glass pressing plate 24 connected thereto to effectively press the plant samples inside the sampling platform 12. Through such pressing operations, the original form of the plant samples can be extremely effectively maintained. In the subsequent transportation, processing and other series of processes, the sample breakage caused by interference from external factors can be avoided, and the integrity of the sample can be effectively ensured, thereby providing a reliable sample basis for precise detection work, helping to obtain accurate and complete data information during the detection process, improving the scientificity and effectiveness of research and analysis of plant samples, and promoting the smooth development of related plant research work.
[0030] Working principle: when it is necessary to clean the grinding table 2, the sliders 10 on both sides are moved. The sliders 10 will slide inside the side table 9 after being stressed. The sliding of multiple sliders 10 further pushes the block 7 stuck inside the side table 9. The block 7 is further stressed and drives the connecting rod 6 of its side wall to rotate and push the slider 1 5. The slider 1 5 is then stressed and slides inside the plug column 3. After multiple blocks 7 slip off from the inside of the side table 9, the collar 8 and the plug column 3 are no longer engaged, and the plug column 3 can be pulled out from the inside of the collar 8 to realize the disassembly of the grinding table 2. When the plug column 3 is re-engaged with the collar 8, the tension of the spring 4 first ensures that the slider 1 5 can push the block 7 to remain stable in the side table 9, and the tension spring 11 can ensure that the reset of the slider 2 10 will not accidentally touch the block 7 to make it slip off. The grinding table 2 can be quickly disassembled and cleaned comprehensively and carefully to ensure that there is no sample residue and cross contamination. If plant samples, such as leaves, need to be pressed When the handle 12 is closed, the electric push rod 14 is started. After starting, the electric push rod 14 pushes the push column 17, so that the push column 17 first slides horizontally inside the straight groove 15. The sliding process of the push column 17 further pushes the connecting wheel 18 at one end thereof. When the position of the connecting wheel 18 changes, it will push the telescopic rod 19 on its outer wall, so that the telescopic rod 19 rotates inside the turntable 16 and changes its own inclination angle. The change in the angle of the telescopic rod 19 will push the rotating rod 20 at one end thereof, so that the rotating rod 20 also rotates inside the side plate 23 and pushes and pulls the side plate 23. The force applied to the side plate 23 further drives the sliding shaft 22 at the bottom to slide vertically inside the hanging platform 21. The vertical sliding process of the hanging platform 21 will drive the glass pressing plate 24 to effectively press the plant sample inside the sampling platform 12. Through pressing, the original shape of the sample can be maintained, the sample can be prevented from being broken during subsequent transportation and processing, the integrity of the sample is ensured, and a reliable sample basis is provided for accurate detection.
[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
