Description

Technical Field

[0001] This application relates to fertilizer and pesticide detection technology, and in particular to an oscillating density meter suitable for pesticide detection. Background Technology

[0002] In modern agricultural production, the widespread use of pesticides has effectively ensured crop yields, but pesticide residue problems have also arisen. Excessive pesticide residues not only pose a potential threat to human health, but may also disrupt the balance of the ecological environment. Therefore, accurate and efficient pesticide residue detection has become an important part of food safety supervision and environmental protection.

[0003] A search revealed Chinese patent publication number CN217505542U, which discloses a density meter for fertilizer and pesticide testing. The meter includes an electronic scale with a weighing platform movably connected to its top. A float is mounted on the top of the electronic scale, and a suspension rope is fixedly connected to the top of the float. This density meter for fertilizer and pesticide testing incorporates a positioning plate, a sliding groove, a slider, a weighing platform, a limiting groove, and a limiting plate. During testing, a beaker containing the fertilizer and pesticide solution is placed at the center of the top of the weighing platform. The positioning plate is then pulled, causing the two side positioning plates to fit against the sides of the beaker for positioning. The slider at the bottom of the positioning plate moves within the sliding groove to limit the positioning plate's position. Furthermore, the two side limiting plates can be symmetrically positioned by the limiting groove to limit the weighing platform, ensuring the balance of the weighing platform during weighing. This improves the stability during weighing and solves the problem of insufficient stability of electronic scales used for weighing during testing.

[0004] The aforementioned patent specification mentions that "a column is fixedly connected to one end of the top of the electronic scale, a through groove is provided inside the column, a lifting plate is fixedly connected to the outside of the suspension rope, a slot is opened at one end of the lifting plate, a fixing bolt is movably connected to one end of one side of the lifting plate, and the fixing bolt passes through the lifting plate and the through groove and extends to the other side of the lifting plate where a fixing nut is movably connected." However, some devices cannot automatically clean the connecting pipes, resulting in a reduced service life. In response to the aforementioned related technologies, an oscillating density meter suitable for pesticide detection is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide an oscillating density meter suitable for pesticide detection, aiming to improve the problem that some devices cannot automatically clean themselves.

[0006] The oscillating density meter for pesticide detection provided in this application adopts the following technical solution: The above technical solution provides an oscillating density meter suitable for pesticide detection, comprising a supporting shell, a cleaning mechanism fixedly connected to the outside of the supporting shell, a clamping and fixing mechanism fixedly connected to the outside of the supporting shell, a driving component for driving, a rotating cleaning column fixedly connected to the outside of the driving component, a cleaning brush fixedly connected inside the rotating cleaning column, a protective shell rotatably connected to the outside of the rotating cleaning column, and a rubber connecting ring fixedly connected to the top of the protective shell.

By adopting the above technical solution, the drive component includes a rotary motor, the drive end of the rotary motor is fixedly connected to a rotary connecting column, and the bottom of the rotary motor is fixedly connected to the bottom of the protective shell.

[0009] Preferably, the rotating motor provides stable rotational power, improving the cleaning effect. The rotating connecting column serves as a transmission component, ensuring efficient power transmission and reducing energy loss. The motor is fixed to the bottom of the protective shell, lowering the center of gravity, enhancing the stability of the cleaning process, and reducing vibration interference. The modular design facilitates overall disassembly and maintenance, reducing maintenance costs. The fully enclosed protective shell effectively prevents cleaning fluid leakage and extends the service life of the equipment. By adopting the above technical solution, the outer side of the rotating connecting column is rotatably connected to the inside of the protective shell, and the outer side of the rotating cleaning column is rotatably connected to the inner side of the protective shell.

[0010] Preferably, the dual-support design enhances rotational stability, reduces shaking during the cleaning process, makes the brush contact the inner wall of the container more even, improves the cleaning effect, protects the outer shell, effectively isolates the cleaning liquid from the external environment, prevents liquid leakage and damage, and extends the service life of the equipment. By adopting the above technical solution, the external part of the cleaning brush is rotatably connected to the inside of the protective shell, and the external part of the rotating cleaning column is rotatably connected to the inside of the rubber connecting ring.

[0011] Preferably, the dual rotation fulcrum greatly improves cleaning stability, reduces vibration interference, makes the brush fit more tightly against the inner wall of the container, improves cleaning efficiency, extends the life of core components, and is compatible with a variety of testing containers.

By adopting the above technical solution, a sliding clamping block is fixedly connected to the outside of the sliding connecting block, and a sliding track is slidably connected to the outside of the sliding connecting block.

[0012] Preferably, the system operates with reduced noise, improving the comfort of the operating environment, enhancing positioning accuracy, meeting the transmission requirements of the equipment, extending the maintenance cycle, and significantly reducing equipment operation and maintenance costs; By adopting the above technical solution, the bottom of the sliding track is fixedly connected to the outside of the supporting shell, and a supporting rotating column is fixedly connected to the outside of the sliding connecting block.

[0013] Preferably, the subsequent transmission mechanism provides support, the connection between the sliding rail and the support shell improves the vibration resistance of the system, the modular design improves assembly efficiency, and damaged parts can be quickly replaced during maintenance; By adopting the above technical solution, a connecting rotating column is rotatably connected to the outside of the first supporting rotating column, and a second supporting rotating column is rotatably connected to the inside of the connecting rotating column, i.e., the end away from the first supporting rotating column. A rotating connecting block is fixedly connected to the outside of the second supporting rotating column. The outside of the rotating connecting block is rotatably connected to the outside of the sliding track. The outside of the connecting rotating column is rotatably connected to the outside of the sliding track.

The outside of the telescopic connecting column is slidably connected to the outside of the sliding track.

[0014] The preferred design features a multi-rotation connection that allows the equipment to flexibly adjust its angle and direction, significantly improving its operating range and adaptability to meet the needs of different work scenarios. The cooperation between the sliding rail and various components ensures smoother and more stable movement, reducing the risk of jamming and malfunctions, and extending the service life of the equipment. The telescopic cylinder provides stable power, and the sliding adjustment of the connecting telescopic column enhances the flexibility of the equipment's operation, improving work efficiency and quality.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. When the rotating motor starts, it drives the rotating connecting column to rotate, which in turn drives the rotating cleaning column and cleaning brush to rotate, realizing mechanical brushing of the inner wall of the pipe. At the same time, the rubber connecting ring tightly clamps and fixes the pipe to ensure the stability of the cleaning process. In addition, the built-in ultrasonic generator works in conjunction to clean stubborn dirt and impurities in the pipe. The combination of mechanical brushing and ultrasonic cleaning can not only quickly remove the attachments on the inner wall of the pipe, but also deeply clean the tiny gaps, prevent the residue from corroding the pipe, significantly extend the service life of the pipe, reduce the maintenance costs and replacement frequency caused by pipe blockage and corrosion, and improve the reliability and stability of equipment operation. 2. The telescopic cylinder drives the connecting telescopic column to extend and retract, causing the sliding connecting block to slide along the sliding track. The movement of the sliding connecting block causes the supporting rotating column to slide synchronously, and through the connecting rotating column, it drives the rotating connecting block to rotate, thereby driving the sliding clamping block to move inward, achieving a stable clamping of the cleaning mechanism. This ensures that the cleaning mechanism remains stable during operation, reducing the decrease in cleaning effect caused by vibration or displacement. The adjustable clamping force ensures both the reliability of the fixation and prevents damage to the cleaning mechanism. This modular fixing method also facilitates the quick replacement and maintenance of the cleaning mechanism, significantly improving the efficiency of equipment use and reducing downtime and maintenance costs.

[0017] The following is in conjunction with the appendix Figure 1-Appendix Figure 5 This application will be described in further detail.

[0018] A vibrating density meter suitable for pesticide detection, refer to Figures 1 to 4 The system includes a supporting housing 1, which serves as the basic frame of the entire density meter. A cleaning mechanism 2 and a clamping and fixing mechanism 3 are fixedly connected to the outside of the supporting housing 1. The cleaning mechanism 2 includes a drive assembly 21 for driving, and a rotating cleaning column 22 is fixedly connected to the outside of the drive assembly 21, transmitting motor power to the rotating cleaning column 22. A cleaning brush 23 is fixedly connected inside the rotating cleaning column 22, removing pesticide residues from the outside of the pipe through high-speed rotation and physical friction. A protective housing 24 is rotatably connected to the outside of the rotating cleaning column 22, and a rubber connecting ring 25 is fixedly connected to the top of the protective housing 24 to isolate the cleaning area. The domain provides a connection between the pipe and the cleaning mechanism 2. The drive assembly 21 includes a rotary motor 211, which provides rotational power to drive the cleaning components to operate. The drive end of the rotary motor 211 is fixedly connected to a rotary connecting column 212. The bottom of the rotary motor 211 is fixedly connected to the bottom of the protective housing 24. When the rotary motor 211 is started, it drives the cleaning brush 23 to rotate. The outside of the rotary connecting column 212 is rotatably connected to the inside of the protective housing 24. The outside of the rotary cleaning column 22 is rotatably connected to the inside of the protective housing 24. The outside of the rotary cleaning column 22 is rotatably connected to the inside of the protective housing 24. The outside of the rotary cleaning column 22 is rotatably connected to the inside of the rubber connecting ring 25. Specifically, the rotating motor 211 drives the cleaning brush 23 to rotate at high speed, which, combined with the flexible seal of the rubber connecting ring 25, achieves all-round physical cleaning of the outer wall of the pipe, improving the pesticide residue removal rate. The double-layer protective shell 24 avoids corrosion of electronic components and reduces the equipment failure rate. The combination design of the clamping block 38 and the cleaning brush 23 ensures the cleaning effect while avoiding scratches on the pipe surface, thus extending the replacement cycle of key components.

[0019] Reference Figure 1 , Figure 3 and Figure 5The clamping and fixing mechanism 3 includes a telescopic cylinder 31. A connecting telescopic column 32 is fixedly connected to the driving end of the telescopic cylinder 31, providing linear driving force and controlling the opening and closing of the sliding clamping block 38. A sliding connecting block 33 is fixedly connected to the outer end of the connecting telescopic column 32, i.e., the end furthest from the telescopic cylinder 31. The sliding clamping block 38 is fixedly connected to the outer side of the sliding connecting block 33, serving as a fulcrum for the linkage mechanism to ensure the accuracy of the motion trajectory. When the telescopic cylinder 31 extends, it drives the sliding clamping block 38 to move inward through the linkage mechanism. A sliding rail 39 is slidably connected to the outer side of the sliding connecting block 33. The bottom of the sliding rail 39 is fixedly connected to the outer side of the supporting shell 1. The external fixed connection is a support rotating column 34, the external rotatable connection of the support rotating column 34 is a connecting rotating column 35, the internal connection of the connecting rotating column 35 (i.e., the end away from the support rotating column 34) is rotatably connected to a support rotating column 36, converting linear motion into rotational motion to achieve linkage clamping. The external fixed connection of the support rotating column 36 is a rotating connecting block 37, the external rotatable connection of the rotating connecting block 37 is to the outside of the sliding rail 39, the external rotatable connection of the connecting rotating column 35 is to the outside of the sliding rail 39, the external fixed connection of the telescopic cylinder 31 is to the outside of the sliding rail 39, and the external slidable connection of the connecting telescopic column 32 is to the outside of the sliding rail 39.

[0020] Specifically, the linkage mechanism transforms the linear motion of the telescopic cylinder 31 into the rotational clamping action of the sliding clamping block, generating greater clamping force and making the workpiece more securely fixed. The design of the sliding track 39 ensures smooth movement of the sliding connecting block 33. The telescopic cylinder 31, as the power source, has a fast response speed, enabling rapid clamping and releasing operations, which helps improve work efficiency. This structural design is compact, occupies little space, and can adapt to different equipment layouts. The linkage mechanism experiences balanced force during movement, reducing component wear and extending the service life of the mechanism.

[0021] The implementation principle of this application embodiment is as follows: when the rotating motor 211 starts running, it drives the rotating connecting column 212 to rotate, thereby driving the rotating cleaning column 22, which in turn drives the cleaning brush 23 to rotate, thereby cleaning the pipes that need to be cleaned inside. At the same time, the rubber connecting ring 25 provides a clamping and fixing effect for the pipes, and the internal ultrasonic waves clean the inside, thereby achieving the effect of cleaning the pipes and increasing the service life of the pipes.

[0022] When the cleaning mechanism 2 needs to be fixed, the telescopic cylinder 31 is operated, which drives the telescopic column 32 to telescopically extend and retract, thereby causing the sliding connecting block 33 to slide. This causes the supporting rotating column 34 to slide, which in turn causes the connecting rotating column 35 to rotate, which in turn causes the supporting rotating column 36 to rotate, which in turn causes the rotating connecting block 37 to rotate. This causes the sliding connecting block 33 to slide on the sliding track 39, which in turn causes the sliding clamping block 38 to move inward, thereby achieving the effect of clamping and fixing the cleaning mechanism 2.

[0023] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
