Description

Technical Field

[0001] This invention belongs to the field of pesticide production technology, specifically a sampling device for biological pesticide production. Background Technology

[0002] Biopesticides are pesticide formulations that utilize living organisms or their metabolites to control pests, pathogens, weeds, nematodes, rodents, and other harmful organisms, or pesticide formulations with specific effects through biomimetic synthesis. During the production of biopesticides, it is necessary to sample and analyze the pesticide solution to ensure production quality.

[0003] Patent CN220751714U discloses a sampling device for biopesticide production, including a pesticide storage tank. A sampling mechanism is provided on one side of the pesticide storage tank. The sampling mechanism includes a support frame. A groove is opened on the side of the support frame away from the pesticide storage tank. A collection tube is slidably connected to the inner wall of the groove. A clamping plate is engaged with the outer wall of the collection tube. A control rope is fixedly installed at one end of the top of the clamping plate. A winding roller is fixedly connected to the other end of the control rope. The side of the winding roller is rotatably connected to the support frame. A collection port is opened at one end of the collection tube. A sealing piston is slidably connected to the inner wall of the collection tube. When it is necessary to sample the biopesticide, the support frame can be inserted into the bottom of the pesticide container. Then, by pulling the control rope at the top of the support frame, the sealing piston slides inside the collection tube, changing the air pressure inside the collection tube, and finally achieving the function of absorbing the pesticide liquid.

[0004] However, the above technical solutions still have the following shortcomings in practical applications: When sampling pharmaceutical solutions, glass measuring cups are used to collect the samples for easier subsequent analysis. Furthermore, to improve the accuracy of the analytical results, samples are typically taken from different depths, so multiple glass measuring cups are used to collect the samples before analyzing them together. However, in some cases, the glass measuring cups lack lids. If multiple measuring cups are placed together and shake due to compression, collision, or other factors, the pharmaceutical solution in the measuring cups can easily overflow. This not only affects the amount of pharmaceutical solution collected but also causes mixing of solutions from different depths, thus impacting the accuracy of the subsequent analytical results.

[0024] One end of the lifting plate 4 is threadedly connected to a threaded rod 57. Both ends of the threaded rod 57 are rotatably mounted on the frame 2. A motor 58 is fixedly connected to one side of the upper end of the frame 2. The output end of the motor 58 is fixedly connected to one end of the threaded rod 57. A cylinder 17 is fixedly connected to one side of the lifting plate 4. The piston end of the cylinder 17 is fixedly connected to one side of the mounting plate 20.

[0025] A motor 25 is fixedly connected to one side of the upper end of the mounting plate 20. The output end of the motor 25 is fixedly connected to one end of the connecting rod 26. An air pump 29 is fixedly connected to one side of the mounting plate 20. A hose 30 is connected to the air inlet end of the air pump 29. One end of the hose 30 is connected to one side of the adsorption tube 31.

[0026] A second motor 24 is fixedly connected to one side of the upper end of the fixed plate 22. The output end of the second motor 24 is fixedly connected to one end of the film roll 23. Slide rods 36 are fixedly connected to both sides of the upper end of the fixed plate 22. Pressure rollers 38 are slidably connected to slide rods 36. Support rollers 39 are rotatably set on one side of the upper end of the fixed plate 22. Slide rod 34 is fixedly connected to one side of the upper surface of the fixed plate 22. Blade plate 33 is slidably connected to slide rod 34. Cutting plate 35 is fixedly connected to one side of the upper surface of the fixed plate 22.

[0027] A spring 37 is fitted on one side of the slide bar 36. One end of the spring 37 is fixedly connected to one end of the pressure roller 38, and the other end is fixedly connected to the fixed plate 22. A cylinder 32 is fixedly connected to one side of the lower end face of the fixed plate 22. The piston end of the cylinder 32 is fixedly connected to one end of the blade plate 33.

[0028] Specifically, in existing technologies, when sampling a pharmaceutical solution, glass measuring cups are used to collect the sampled solution for easier subsequent analysis. Furthermore, to improve the accuracy of the analytical results, samples are typically taken from different depths, so multiple glass measuring cups are used to collect the solution before analyzing it collectively. However, in some cases, the glass measuring cups lack lids. If multiple measuring cups are placed together and shake due to compression, collision, or other factors, the solution in the measuring cups can easily overflow. This not only affects the amount of solution collected but also causes mixing of solutions from different depths, thus impacting the accuracy of the subsequent analytical results.

[0029] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: Place the base plate 1 next to the medicine storage tank and position the suction head 6 above it. Place the glass measuring cup on the electric chuck 9 and secure it in place. Then, insert the outlet tube 15 into the glass measuring cup. Next, use the motor 10 to drive the rotating wheel 11 to unwind the rope 12, causing the counterweight 7 and suction head 6 to descend and enter the medicine solution. Simultaneously, the liquid level sensor 16 monitors the sinking depth. The liquid level sensor 16 is an existing sensor capable of monitoring sinking depth, and will not be described in detail here. The operator can observe the depth of the suction head 6 in real time on the display screen. When the suction head 6 reaches the appropriate depth, start the liquid pump 14. The liquid pump 14 draws the medicine from the storage tank, injects it into the glass measuring cup through the inlet tube 8 and outlet tube 15, thus completing the medicine sampling. Once a sufficient amount of medicine has been collected in the glass measuring cup, turn off the liquid pump 14 and remove the outlet tube 15 from the glass measuring cup.

[0030] In the initial state, one end of the film roll 23 is positioned between the pressure roller 38 and the support roller 39, and is pressed by the spring 37. The cylinder 17 drives the mounting plate 20 to move laterally, aligning the clamping ends of the two finger cylinders 21 with the edge of the film, and clamping the edge of the film through the finger cylinders 21. Then, the motor 24 drives the film roll 23 to rotate, unwinding the film, while the finger cylinders 21 pull the film until the part of the film pulled out can cover the top of the glass measuring cup. Then, the motor 25 drives the connecting rods 26 and 27 to rotate, causing the connecting block 28 to move laterally and adjusting the lateral position of the adsorption tube 31. Then, the cylinder 61 drives the adsorption tube 31 to descend, so that the adsorption tube 31 is attached to one side of the film surface. Then, the air pump 29 is started, and the film is adsorbed onto the adsorption tube 31 by negative pressure adsorption. Then, the cylinder 32 drives the blade plate 33 to descend, and the film is cut by the cooperation of the blade plate 33 and the cutting plate 35. At this time, the two edges of the film are fixed by negative pressure adsorption and clamping respectively. Then, the cut membrane is driven to descend by the rotation of the threaded rod 57 driven by motor 6 58 until the membrane adheres to the upper end of the glass measuring cup. The membrane then covers the mouth of the glass measuring cup. The glass measuring cup is then removed from the electric chuck 9. The above operation is repeated so that the mouth of each glass measuring cup containing the medicine is covered by the membrane. When the glass measuring cup is placed, if the medicine splashes due to shaking, the splashed medicine will be intercepted by the membrane and will not overflow, thus ensuring the amount of medicine collected. At the same time, it also avoids the situation where the medicine in different glass measuring cups mixes, which would affect the accuracy of subsequent analysis results.

[0031] In this embodiment, as Figure 7 , Figure 8 , Figures 10-13 As shown, a cup mouth reinforcement component is also provided on the fixing plate 22; The cup mouth reinforcement assembly includes a grooved plate 45 fixedly connected to one side of the fixed plate 22. An adjusting plate 43 is slidably connected to the groove of the grooved plate 45. An annular tube 47 is fixedly connected to one end of the adjusting plate 43. The annular tube 47 is radially evenly distributed and connected to multiple branch tubes 52. One end of each branch tube 52 is connected to a nozzle 51. Multiple radial rods 62 are radially evenly distributed and slidably connected to the bottom of the annular tube 47. One end of each radial rod 62 is fixedly connected to the nozzle 51. A threaded rod 56 is provided at the lower end of the radial rod 62, and a threaded rod 56 is sleeved on the threaded rod 56. There is a wrapping cloth 54, which is made of elastic material and has a circular hole in the middle. A threaded rod 56 is threaded to a nut 55. The threaded rod 56 and the nut 55 cooperate to press the wrapping cloth 54 onto the radial rod 62. A cylinder 53 is fixedly connected to one side of the annular tube 47. Two sliding columns 60 are slidably connected to the piston end of the cylinder 53. A pressure ball 59 is fixedly connected to one end of the sliding column 60. A motor 40 is fixedly connected to one side of the upper end of the base plate 1. The output end of the motor 40 is fixedly connected to one side of the bottom of the electric chuck 9.

[0032] One end of the adjusting plate 43 is threadedly connected to a threaded rod 44. Both ends of the threaded rod 44 are rotatably mounted on the slot plate 45. One end of the slot plate 45 is fixedly connected to a motor 46. The output end of the motor 46 is fixedly connected to one end of the threaded rod 44. One end of the radial rod 62 is rotatably connected to a connecting rod 49. One end of the connecting rod 49 is rotatably connected to a transmission ring 48. One side of the annular tube 47 is fixedly connected to an electric actuator 50. The piston end of the electric actuator 50 is fixedly connected to one side of the transmission ring 48.

[0033] A spring 19 is fitted on one side of the sliding column 60. One end of the spring 19 is fixedly connected to one end of the sliding column 60, and the other end is fixedly connected to one end of the pressure ball 59.

[0034] A glue cylinder 3 is fixedly connected to one side of the upper end face of the base plate 1. A glue pump 41 is connected and fixed to one side of the upper end of the glue cylinder 3. A glue outlet pipe 42 is connected to the glue outlet end of the glue pump 41. One end of the glue outlet pipe 42 is connected to one side of the annular pipe 47.

[0035] Specifically, in the above embodiments, although the film can be covered over the mouth of the glass measuring cup to prevent the medicine from spilling out, the film is lightweight and therefore easily displaced by external force after being covered over the mouth of the glass measuring cup, and falls off the mouth, thus affecting the normal coverage of the mouth of the glass measuring cup.

[0036] Therefore, to solve the above problems, in this embodiment, before the film is covered on the glass measuring cup, the annular tube 47 is raised and lowered by the motor 46 driving the threaded rod 44 to rotate, so that the nozzle 51 is aligned with the edge of the glass measuring cup. Subsequently, the electric push rod 50 drives the transmission ring 48 to move, so that the radial rod 62 slides on the annular tube 47 under the transmission of the connecting rod 49, so that the nozzle 51 is close to the outer wall of the glass measuring cup to a suitable position. In addition, the size of the wrapping cloth 54 will also change due to the movement of the radial rod 62, so that the edge of the circular hole of the wrapping cloth 54 is tightly attached to the outer wall of the glass measuring cup. Then the glue pump 41 is started, and the glue in the glue tank 3 is sprayed onto the outer wall of the glass measuring cup through multiple nozzles 51. During spraying, motor 40 drives electric chuck 9 to rotate, ensuring the adhesive adheres evenly around the rim of the glass measuring cup. Because the wrapping cloth 54 is in contact with the outer wall of the glass measuring cup, it intercepts the adhesive as it slides down the surface, concentrating it in a fixed area. The cut film is then placed over the glass measuring cup. The film edge, under gravity, hangs down along the rim. Cylinder 3 53 moves the clamping ball 59, pressing the film firmly against the rim. Simultaneously, the electric chuck 9 rotates, causing relative movement between the clamping ball 59 and the glass measuring cup. This adhesive adheres the film to the rim, ensuring a strong bond and stability. This prevents the film from easily detaching from the rim due to external force, thus ensuring proper coverage of the glass measuring cup. In addition, when maintenance and cleaning of the wrapping cloth 54 are required, the wrapping cloth 54 can be removed by unscrewing the nut 55 to ensure the effectiveness of the wrapping cloth 54.

[0037] Working Principle: Place the base plate 1 next to the medicine storage tank and position the suction head 6 above it. Place the glass measuring cup on the electric chuck 9 and secure it in place. Then, insert the outlet tube 15 into the glass measuring cup. Next, use the motor 10 to drive the rotating wheel 11 to unwind the rope 12, causing the counterweight 7 and suction head 6 to descend and enter the medicine solution. Simultaneously, the liquid level sensor 16 monitors the sinking depth. The liquid level sensor 16 is an existing sensor capable of monitoring sinking depth, and will not be described in detail here. The operator can observe the depth of the suction head 6 in real time on the display screen. When the suction head 6 reaches the appropriate depth, start the liquid pump 14. The liquid pump 14 draws the medicine from the storage tank, injects it into the glass measuring cup through the inlet tube 8 and outlet tube 15, thus completing the medicine sampling. Once a sufficient amount of medicine has been collected in the glass measuring cup, turn off the liquid pump 14 and remove the outlet tube 15 from the glass measuring cup. In the initial state, one end of the film roll 23 is positioned between the pressure roller 38 and the support roller 39, and is pressed by the spring 37. The cylinder 17 drives the mounting plate 20 to move laterally, aligning the clamping ends of the two finger cylinders 21 with the edge of the film, and clamping the edge of the film through the finger cylinders 21. Then, the motor 24 drives the film roll 23 to rotate, unwinding the film, while the finger cylinders 21 pull the film until the part of the film pulled out can cover the top of the glass measuring cup. Then, the motor 25 drives the connecting rods 26 and 27 to rotate, causing the connecting block 28 to move laterally and adjusting the lateral position of the adsorption tube 31. Then, the cylinder 61 drives the adsorption tube 31 to descend, so that the adsorption tube 31 is attached to one side of the film surface. Then, the air pump 29 is started, and the film is adsorbed onto the adsorption tube 31 by negative pressure adsorption. Then, the cylinder 32 drives the blade plate 33 to descend, and the film is cut by the cooperation of the blade plate 33 and the cutting plate 35. At this time, the two edges of the film are fixed by negative pressure adsorption and clamping respectively. Then, the cut membrane is driven to descend by the rotation of the threaded rod 57 driven by motor 6 58 until the membrane adheres to the upper end of the glass measuring cup. The membrane then covers the mouth of the glass measuring cup. The glass measuring cup is then removed from the electric chuck 9. The above operation is repeated so that the mouth of each glass measuring cup containing the medicine is covered by the membrane. When the glass measuring cup is placed, if the medicine splashes due to shaking, the splashed medicine will be intercepted by the membrane and will not overflow, thus ensuring the amount of medicine collected. At the same time, it also avoids the situation where the medicine in different glass measuring cups mixes, which would affect the accuracy of subsequent analysis results.

[0038] Before the film is applied to the glass measuring cup, the annular tube 47 is raised and lowered by the rotation of the threaded rod 44 driven by motor 46, aligning the nozzle 51 with the edge of the glass measuring cup rim. Subsequently, the electric push rod 50 moves the transmission ring 48, causing the radial rod 62 to slide on the annular tube 47 under the transmission of the connecting rod 49, bringing the nozzle 51 closer to the outer wall of the glass measuring cup to a suitable position. The size of the wrapping cloth 54 also changes due to the movement of the radial rod 62, ensuring that the edges of the circular holes in the wrapping cloth 54 are tightly fitted to the outer wall of the glass measuring cup. Then, the glue pump 41 is started, and the glue in the glue cartridge 3 is sprayed onto the outer wall of the glass measuring cup through multiple nozzles 51. Simultaneously, motor 40 drives the electric chuck 9 to rotate, ensuring that the glue is evenly adhered around the rim of the glass measuring cup. Because the wrapping cloth 54 is in contact with the outer wall of the glass measuring cup, it intercepts the glue as it slides down the surface, ensuring that the glue is concentrated in a fixed area. Next, the cut film is placed over the glass measuring cup. The film edge will droop along the rim of the cup under gravity. Then, cylinder 3 53 moves the clamping ball 59, pressing the film firmly against the rim of the glass measuring cup. Simultaneously, the electric chuck 9 rotates, causing relative movement between the clamping ball 59 and the glass measuring cup. This adhesive then adheres the film to the rim of the glass measuring cup, ensuring a firm bond and stability. This prevents the film from easily detaching from the rim due to external force, thus ensuring proper coverage of the glass measuring cup. Furthermore, when maintenance and cleaning of the wrapping cloth 54 are required, it can be removed by unscrewing the nut 55 to maintain its effectiveness.
