Technical Field

[0001] This utility model belongs to the field of pesticide adjuvant extraction technology, specifically a pesticide adjuvant extraction test device. Background Technology

[0002] In modern agricultural production, pesticide adjuvants, as an important component of pesticide formulations, play a crucial role in enhancing pesticide efficacy and improving the physicochemical properties of pesticides. Pesticide adjuvants can enhance the adhesion, penetration, and distribution of active pesticide ingredients on target organisms, thereby increasing pesticide utilization, reducing pesticide usage, and ultimately minimizing environmental pollution. Currently, common methods for extracting pesticide adjuvants include solvent extraction, distillation, and adsorption. Solvent extraction involves selecting a suitable organic solvent to extract and separate pesticide adjuvants.

[0003] Existing solvent extraction methods are cumbersome and have low automation. They require manual shaking, settling, and separation during extraction, which is not only time-consuming but also dependent on the operator's experience, easily leading to large errors in parallel samples. Therefore, we propose a pesticide adjuvant extraction experimental device. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a pesticide adjuvant extraction test device, which effectively solves the problems of the existing solvent extraction method being cumbersome to operate, having a low degree of automation, requiring manual shaking, standing for layering, and manual separation during extraction, which is not only time-consuming but also dependent on the operator's experience and easily leads to large errors in parallel samples.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pesticide adjuvant extraction test device, comprising a pesticide adjuvant temperature control tank, a sealing cover plate on the top of the pesticide adjuvant temperature control tank, a stirring assembly in the middle of the sealing cover plate, the pesticide adjuvant temperature control tank and the sealing cover plate being connected by a set of hydraulic cylinders, a limiting mechanism inside the stirring assembly, the stirring assembly including a motor, the motor being located in the middle of the surface of the sealing cover plate, an I-shaped shaft connected to the movable end of the motor, a rotating shaft fixedly connected to the bottom of the I-shaped shaft, a plurality of guide rods uniformly fixed in a ring on the outer side of the rotating shaft, a movable frame sleeved on the outside of the rotating shaft and guide rods, a slot being opened inside the movable frame, and a plurality of stirring rods symmetrically fixed on both sides of the surface of the movable frame.

[0006] Preferably, the stirring assembly further includes a scraper, which is fixed at the end of the stirring rod away from the movable frame. A sealing sleeve is fitted on the outer side of the bottom of the movable frame, and a hydraulic cylinder is embedded inside the rotating shaft.

[0007] Preferably, the assembly consisting of the rotating shaft and several guide rods can be matched and engaged inside the slot, and the outer side of the guide rods is arc-shaped.

[0008] Preferably, the outer side of the scraper is made of rubber, and the outer side of the scraper is in contact with the inner wall of the pesticide adjuvant temperature control tank.

[0009] Preferably, the limiting mechanism includes a limiting block, which is fixed to the movable end of the hydraulic cylinder. A set of springs is symmetrically arranged inside the limiting block, and a locking block is connected to the outer end of the spring. A pressing block is attached to the side of the locking block away from the spring.

[0010] Preferably, the locking block forms an elastic structure with a spring and a limiting block. When the spring is in the normal state, the locking block is partially engaged inside the movable frame.

[0011] Preferably, the bottom side of the movable frame is provided with an inclined transition section to assist the movement of the pressing block, the pressing block can move horizontally inside the movable frame, and the sealing sleeve can fit and seal the outer end of the pressing block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The pesticide adjuvant temperature control tank provides a stable temperature environment, and the sealing cover ensures good airtightness, reducing the loss of active ingredients during extraction. Hydraulic cylinder one allows for flexible adjustment of the sealing cover's opening and closing, facilitating material feeding and equipment maintenance. When the motor drives the I-shaped shaft and rotating shaft, the guide rod and slot work together to drive the movable frame to rotate synchronously, ensuring the stirring rod thoroughly mixes the material and improves mixing uniformity. The arc-shaped guide rod ensures transmission stability and reduces stress concentration when in contact with the movable frame. The scraper fits against the inner wall of the pesticide adjuvant temperature control tank, effectively removing residual material and preventing scale buildup that could affect temperature control efficiency. Hydraulic cylinder two within the rotating shaft drives the limiting mechanism and movable frame to move axially along the guide rod, allowing for flexible adjustment of the stirring height to suit different liquid levels. During the static stratification process, the stirring rod and scraper can be moved upwards away from the mixed solution.

[0013] 2. The inclined transition section on the bottom side of the movable frame guides the locking block when the movable frame is combined with the rotating shaft, allowing the locking block to gradually disappear inside the limiting block. This facilitates the connection between the movable frame and the limiting block when the limiting block is locked to the bottom of the movable frame. When the movable frame needs to be disassembled, first remove the sealing sleeve, then press the button inward to push the locking block out of the movable frame. At this time, the movable frame is unrestrained and can be directly pulled out. The sealing sleeve's fit and seal against the outer end of the button prevents material from seeping into the limiting mechanism and causing component jamming or corrosion, thus extending the service life of the limiting mechanism.

A movable frame 305 is fitted around the guide rod 304. A slot 306 is provided inside the movable frame 305. The assembly consisting of the rotating shaft 303 and several guide rods 304 can be matched and engaged inside the slot 306. The outer side of the guide rod 304 is arc-shaped. Several stirring rods 307 are symmetrically fixed on both sides of the surface of the movable frame 305. The stirring assembly 3 also includes a scraper 308, which is fixed at the end of the stirring rod 307 away from the movable frame 305. Furthermore, the outer side of the scraper 308 is made of rubber and is in contact with the inner wall of the pesticide adjuvant temperature control tank 1. The movable frame 305 has a sealing sleeve 309 on its outer bottom. A hydraulic cylinder 310 is embedded inside the rotating shaft 303. A stable temperature environment is provided by the pesticide adjuvant temperature control tank 1, which, together with the sealing cover 2, achieves good sealing, reducing the loss of active ingredients during extraction. The hydraulic cylinder 4 can flexibly adjust the opening and closing of the sealing cover 2, facilitating material feeding and equipment maintenance. When the motor 301 drives the I-shaped shaft 302 and the rotating shaft 303 to rotate, the movable frame 305 rotates synchronously through the cooperation of the guide rod 304 and the slot 306, allowing the stirring rod 307 to fully agitate the material. Stirring improves the uniformity of mixing. The arc-shaped guide rod 304 ensures transmission stability and reduces stress concentration when in contact with the movable frame 305. The scraper 308 fits against the inner wall of the pesticide adjuvant temperature control tank 1, which can scrape off residual materials on the tank wall to avoid waste and prevent scale buildup on the tank wall from affecting temperature control efficiency. The hydraulic cylinder 310 in the rotating shaft 303 can drive the limiting mechanism 5 and the movable frame 305 to move axially along the guide rod 304, realizing flexible adjustment of the stirring height to adapt to different liquid level conditions. At the same time, during the static stratification process, the stirring rod 307 and the scraper 308 can be moved upward away from the mixed solution.

[0019] The limiting mechanism 5 includes a limiting block 501, which is fixed to the movable end of the hydraulic cylinder 310. A set of springs 502 are symmetrically arranged inside the limiting block 501. A locking block 503 is connected to the outer end of each spring 502. The locking block 503 forms an elastic structure with the limiting block 501 through the springs 502. When the springs 502 are in their normal state, the locking block 503 is partially engaged with the inner side of the movable frame 305. A pressing block 504 is attached to the side of the locking block 503 away from the springs 502. Furthermore, the bottom inside the movable frame 305 has an inclined transition section to assist the movement of the locking block 503. The pressing block 504 can move horizontally inside the movable frame 305. A sealing sleeve 309 can seal the outer end of the pressing block 504. The sloping transition section on the bottom side can guide the locking block 503 when the movable frame 305 is combined with the rotating shaft 303, so that the locking block 503 gradually disappears into the limit block 501. This makes it convenient for the locking block 503 to pop out when the limit block 501 is locked to the bottom of the movable frame 305, thus realizing the connection between the movable frame 305 and the limit block 501. When the movable frame 305 needs to be disassembled, first remove the sealing sleeve 309, and then press the button 504 inward, so that the button 504 pushes the locking block 503 out of the movable frame 305. At this time, the movable frame 305 is unrestrained and can be directly pulled out. The sealing sleeve 309 adheres to the outer end of the button 504 to prevent materials from seeping into the interior of the limit mechanism 5, causing parts to jam or corrode, thus extending the service life of the limit mechanism 5.
