The two arc-shaped plates are located on the outer sides of the mixing tank, and both arc-shaped plates are made of rubber.

[0026] This utility model has the following beneficial effects:

[0027] 1. In this utility model, when installing the filter shell, first move the two moving blocks relative to each other, causing the arc-shaped block to squeeze the first return spring, so that the locking block moves out of the mounting ring hole. Insert the protrusion on the filter shell into the mounting ring, release the moving blocks, and the spring returns to its original position so that the locking block is locked into the groove of the protrusion, thus completing the installation. During drainage, the liquid is initially filtered by the coarse filter plate to remove large particles, and then filtered by the fine filter plate to remove small particles before being discharged. During cleaning, rotate the right filter shell to remove it from the mounting groove, and then rotate the connecting ring to remove it from the left filter shell. The coarse and fine filter plates can then be disassembled for cleaning. This design facilitates filtration and is easy to disassemble and maintain. It can remove impurities, improve the purity of the agent, ensure uniform spraying of the liquid, and improve the prevention and control effect.

[0028] 2. In this utility model, when using solid agents, the two baffles are first pressed downwards. The baffles move down along the rotating rod, pushing the arc-shaped rod to compress the second return spring, thus exposing the hopper opening. After the agent is poured in, the baffles are released, and the spring returns to its original position, causing the baffles to close the hopper. Then, the motor is started, driving the front transmission rod and gear to rotate, and meshing with the rear gear and transmission rod. The dispersing rollers on the two transmission rods rotate accordingly, breaking up the clumps of agent so that they finally fall into the mixing tank. This design can effectively break up clumps, ensuring that the agent dissolves evenly and has a consistent concentration. At the same time, the entire feeding process is shielded, preventing the powder from scattering, reducing waste, and improving the control effect.

[0029] 3. In this utility model, when moving the mixer, the traction hole on the traction frame can be connected to the traction tool for dragging. During the movement, if the mixing tank sways left and right, two rubber arc plates provide protection and cushioning; if it sways up and down, the damper will contract and drive the buffer rod to move, squeezing the buffer spring. The deformation of the buffer spring absorbs the shaking force. This design makes the equipment easy to move and reduces vibration and impact during transportation, preventing the tank body, support or weld from loosening and deforming due to bumps, thus improving the durability and stability of the equipment.

[0030] 4. In this utility model, when mixing the agent, the agent is first added to the mixing tank through the dosing port, then the water pump is started, and water is injected into the tank through the connecting pipe and the delivery pipe. Then the motor is started, driving the drive wheel, the transmission belt and the driven wheel to rotate the rotating shaft. The stirring blades on the rotating shaft fully mix the agent and water. At the same time, the connecting rods on both sides drive the scraper to rotate, scraping off the liquid adhering to the inner wall of the mixing tank. This achieves uniform mixing of the liquid and can promptly remove the residue on the inner wall, preventing the liquid from drying or deteriorating and affecting the quality of the next batch. This effectively ensures the purity and control effect of the agent. Attached Figure Description

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0047] See appendix Figure 1 -Appendix Figure 12This utility model provides an embodiment of a mobile rice blast control agent mixing and stirring machine, including a traction frame 1, a mixing tank 9 on the upper part of the traction frame 1, a dosing port 10 fixedly connected to the top right side of the mixing tank 9 for easy addition of the agent, a hopper 28 fixedly connected to the top front side of the mixing tank 9, a solid agent crushing and overflow prevention mechanism inside the hopper 28 for crushing clumps of solid agent and for shielding the hopper 28 during crushing to prevent agent overflow, and a liquid outlet 14 fixedly connected to the bottom right side of the mixing tank 9 for discharging liquid. A mounting ring 23 is fixedly connected to the bottom of the port 14. A liquid filtration mechanism is installed on the outside of the mounting ring 23 to facilitate the filtration of the mixed reagents, improving their purity. A mixing mechanism is installed on the left side of the outside of the mixing tank 9 to facilitate the mixing of reagents and water. A movable protective mechanism is installed at the bottom of the mixing tank 9 to facilitate movement and protect it. A warning light 58 is installed on the outside of the traction frame 1 to improve the safety of the equipment during movement. The right side of the traction frame 1 is fixed... A placement basket 47 is connected to facilitate the placement of the required medications. Rollers 2 are installed on both outer sides of the traction frame 1 for easy movement. A traction hole 4 is provided on the left outer side of the traction frame 1 for connection to a traction tool. A support column 5 is rotatably connected to the lower part of the traction frame 1. A bolt 7 is installed on the left inner side of the traction frame 1, with a nut 8 threaded onto the outside of the bolt 7. A placement groove 6 is provided at the lower part of the traction frame 1, and the support column 5 is rotatably connected inside the placement groove 6. The placement groove 6 facilitates the storage of the support column 5. The support column 5 serves to... When there is no towing equipment, the towing frame 1 can be placed in a horizontal position. Guardrails 3 are installed on both sides of the upper part of the towing frame 1. Positioning plates 59 are fixedly connected to the top of the two guardrails 3. Arc plates 60 are fixedly connected to the top of the two positioning plates 59. The two arc plates 60 are set on the outer sides of the mixing tank 9. The two arc plates 60 are made of rubber. Rubber has excellent elasticity and flexibility. When the mixer shakes or vibrates during movement, the arc plates 60 can effectively absorb and disperse the impact force from the mixing tank 9, play a shock absorption and buffering role, and prevent hard collisions between the tank and the supporting structure.

[0048] The liquid filtration mechanism includes a filter housing 15. A protrusion 19 is fixedly connected to the left side of the filter housing 15. Arc-shaped blocks 24 are slidably connected to both sides of the mounting ring 23. Moving blocks 25 are fixedly connected to the outside of each of the two arc-shaped blocks 24. A first return spring 27 is fixedly connected to the middle of each of the two arc-shaped blocks 24. A locking block 26 is fixedly connected to the top of each of the two arc-shaped blocks 24. A coarse filter plate 21 is provided on the left side of the filter housing 15 to facilitate the filtration of larger particles in the liquid. A fine filter plate 22 is provided on the right side of the filter housing 15 to facilitate the filtration of larger particles in the liquid. Plate 22 facilitates the filtration of smaller particles in the liquid medicine. A drain port 16 is fixedly connected to the outside right side of the filter shell 15. A valve 17 is installed on the outside of the drain port 16. The drain port 16 facilitates the discharge of the liquid medicine. A connecting ring 61 is provided in the middle of the filter shell 15. The connecting ring 61 has mounting grooves 18 on both sides inside. The left and right filter shells 15 are threadedly connected to the inside of the two mounting grooves 18. The two protrusions 19 have slots 20 inside. The two locking blocks 26 are inserted into the two slots 20. The slots 20 facilitate the limiting of the protrusions 19.

[0049] Specifically, when installing the filter housing 15 outside the mixer drain port 16, the operator first needs to hold the two moving blocks 25 with both hands and push them in opposite directions. As the two moving blocks 25 move relative to each other, the two arc-shaped blocks 24 fixedly connected to their bottoms also move closer to the center. During this process, the first return spring 27 located between the two arc-shaped blocks 24 is compressed and subjected to force, thus undergoing elastic deformation and storing elastic potential energy for subsequent reset. When the two arc-shaped blocks 24 are relatively close, the two clips fixedly connected to them at the top... Block 26 moves synchronously towards the center, causing the locking block 26, which was originally inserted into the hole inside the mounting ring 23, to disengage from the hole. Then, the two protrusions 19, which are pre-fixed to the left side of the filter shell 15, are accurately aligned and inserted into the positioning areas on both sides of the bottom mounting ring 23 of the drain port 16, so that they are firmly embedded. At this time, the operator slowly releases the two moving blocks 25. Under the reaction force of the first return spring 27, the arc-shaped block 24 gradually returns to its initial position, driving the two locking blocks 26 at the top to return to the outside, and finally inserting into the two protrusions. The slot 20 inside the filter housing 15 provides a secure connection between the filter housing 15 and the drain port 16, ensuring that there will be no loosening or leakage during equipment operation and liquid discharge. During operation, the mixed liquid flows into the filter housing 15 through the drain port 14. The liquid first undergoes primary filtration through the internal coarse filter plate 21, which primarily intercepts larger particles such as incompletely dissolved powder or larger impurities. After coarse filtration, the liquid then flows through the fine filter plate 22 for secondary filtration. The process further removes fine particles or tiny clumps, ensuring the purity and flowability of the filter solution. Finally, the filtered solution is smoothly discharged through drain port 16. Cleaning or maintenance of the coarse filter plate 21 and fine filter plate 22 is equally simple. First, the operator can manually rotate the right-side filter housing 15 to gradually detach it from the mounting groove 18 inside the connecting ring 61. Then, continue rotating the connecting ring 61 to separate it from the external connection structure of the left-side filter housing 15, thus easily disassembling the filter assembly. The disassembled coarse filter plate 21 and fine filter plate 22 can be easily removed for thorough cleaning and inspection to ensure stable filtration performance over a long period. After cleaning or replacement, simply reinstall them in reverse order: realign the filter housing 15 with the connecting ring 61, rotate to secure it, and then connect it to the drain port 16 using the aforementioned snap-fit ​​steps. The entire installation and disassembly process requires no additional tools, is convenient, and saves time and manpower.

[0050] Please see the appendix Figure 9 -Appendix Figure 13The solid drug pulverizing and spill prevention mechanism includes a hopper 28, which is fixedly connected to the top front side of the mixing tank 9. Rotating rods 29 are fixedly connected to both sides of the top of the hopper 28. Baffles 30 are rotatably connected to the outside of each of the two rotating rods 29. The baffles 30 are used to prevent the pulverized drug powder from being trapped. Arc-shaped rods 31 are fixedly connected to the bottom of each of the two baffles 30. The two arc-shaped rods 31 are located on both sides inside the hopper 28. Second return springs 39 are fitted onto the outside of each of the two hoppers 28. Transmission rods 36 are rotatably connected to both sides inside the hopper 28. A motor 35 is fixedly connected to the right side of the front transmission rod 36. Gears 37 are fixedly connected to the left side of each of the two transmission rods 36, and the two gears 37 mesh with each other. Dispersing rollers 38 are fixedly connected to the outside of each of the two transmission rods 36. Roller 38 facilitates the crushing of agglomerated medicine. A water pump 11 is fixedly connected to the top left side of the mixing tank 9. A connecting pipe 13 is fixedly connected to the input end of the water pump 11, and a conveying pipe 12 is fixedly connected to the output end of the water pump 11. The bottom of the conveying pipe 12 is fixedly connected to the inside of the mixing tank 9. A liquid level window 40 is installed on the front side of the outside of the mixing tank 9. A support block 34 is fixedly connected to the left side of the outside of the hopper 28. A motor 35 is fixedly connected to the top of the support block 34. The support block 34 facilitates the fixation of the motor 35. Guide plates 33 are fixedly connected to both sides inside the hopper 28. The guide plates 33 facilitate the guidance of the medicine. Through holes 32 are opened on both sides inside the hopper 28. Two arc-shaped rods 31 are slidably connected inside the two through holes 32. The through holes 32 facilitate the movement of the arc-shaped rods 31.

[0051] Specifically, when using solid pesticides for rice blast control, the operator first presses down on the two baffles 30 installed on top of the hopper 28 with both hands. As the external force is applied, the two baffles 30 rotate along the outer surfaces of the two rotating rods 29 and gradually move downwards. During this process, the downward movement of the baffles 30 will cause the two arc-shaped rods 31 connected to their bottoms to slide downwards inside the through-hole 32. The movement of the arc-shaped rods 31 further compresses the two externally sleeved second return springs 39, causing the second return springs 39 to undergo elastic deformation and store elastic potential energy for the subsequent reset action. When the two baffles 30 have completely moved down and exposed the opening of the hopper 28, Once inside, the operator can stop pressing down, creating an open feeding space above the hopper 28. Then, the pre-weighed solid pesticide for rice blast control is evenly poured into the hopper 28, ensuring no spillage or uneven accumulation. After feeding, the operator slowly releases their hands. The two second return springs 39, upon release, generate a counter-force, pushing the arc-shaped rod 31 upwards and causing the baffle plate 30 to rotate back to its original position along the rotating rod 29. Finally, the two baffle plates 30 close again, covering the upper opening of the hopper 28, thus providing a seal and protection, effectively preventing pesticide powder from scattering into the air during subsequent operations. In order to reduce waste and avoid polluting the working environment, after feeding and sealing are completed, motor 35 is started. The output end of motor 35 is fixedly connected to the front transmission rod 36. Driven by the operation of motor 35, the front transmission rod 36 starts to rotate at high speed, which in turn drives the front gear 37 fixedly connected to its left side to rotate. The rotation of the front gear 37 drives the rear gear 37 to rotate synchronously through meshing transmission. The rear gear 37 then transmits power to the rear transmission rod 36 fixedly connected inside. As the two transmission rods 36 rotate, the two dispersing rollers 38 fixedly connected to their outside start to rotate. The dispersing rollers 38 generate a continuous agitation force during the rotation, which agitates the material in the hopper. The solid pesticide for rice blast control inside container 28 is thoroughly dispersed, breaking up any clumps and making the pesticide particles fine and uniform. This process not only effectively avoids clumping caused by moisture or compaction, but also ensures that the pesticide can come into more complete contact with water or other solutions during the subsequent mixing stage, achieving uniform dissolution and dispersion. After dispersion, the pesticide falls smoothly into the mixing tank 9 below under gravity, providing sufficient raw materials for the next step of pesticide solution preparation. The entire operation is automated from feeding, sealing, dispersion to discharge, simplifying the operation steps, reducing manual intervention, and improving work efficiency. In addition, the baffle 30 effectively isolates dust during pesticide addition and dispersion, preventing solid pesticide particles from floating and spreading into the air, reducing pesticide waste and protecting the respiratory health of operators.By thoroughly dispersing the pesticide, the uniformity of the pesticide concentration is ensured, resulting in a more even distribution of the pesticide effect during subsequent spraying. This enhances the overall effectiveness and stability of rice blast control, achieving the goal of safe and economical use.

[0052] Please see the appendix Figure 10 -Appendix Figure 11 The mobile protective mechanism includes a mounting plate 46, which is fixedly connected to the bottom of the mixing tank 9. A damper 42 is fixedly connected to the bottom of the mounting plate 46. The damper 42 is fixedly connected to the middle of the traction frame 1. An annular block 41 is fixedly connected to the middle of the traction frame 1. Guide rods 43 are fixedly connected to the inner periphery of the annular block 41. Buffer springs 44 are sleeved on the outside of the multiple guide rods 43. Buffer rods 45 are slidably connected to the outside of the multiple guide rods 43. The tops of the multiple buffer rods 45 are rotatably connected to the inner periphery of the mounting plate 46.

[0053] Specifically, during the movement of the rice blast control agent mixing machine, the operator first needs to connect the pre-drilled traction hole 4 on the left side of the traction frame 1 to the external traction tool. During connection, ensure the traction pin is securely inserted into the traction hole 4 and reinforce it with a locking pin or fixing device to prevent it from falling off or loosening during traction. After connection, the mixing machine can be moved. During the movement, the ground may be uneven, bumpy, or have potholes, causing the mixing drum 9 to experience vibrations and impacts from different directions. When the mixing drum 9 sways left and right during movement, the two rubber arc-shaped plates 60 on the outside of the device come into play. The arc-shaped plates 60 are in close contact with the outer wall of the mixing drum 9, and through their excellent elasticity and cushioning characteristics, they provide flexible support and protection for the mixing drum 9, effectively limiting its lateral sway and preventing direct collision between the drum and the supporting structure, thus preventing scratches, deformation, or weld cracks on the drum wall. When encountering large bumps that cause the mixing drum to sway, the mixing drum 9 will be moved. When the tank 9 shakes vertically, the damper 42 at the bottom starts to work. As the damper 42 contracts under force, it drives the four buffer rods 45 connected to its two ends to expand and move in all directions. Under the pushing action of the buffer rods 45, the buffer springs 44 on the four guide rods 43 are compressed synchronously. During the deformation process, the buffer springs 44 absorb and disperse the vertical impact force from the tank body, so that the vibration energy gradually decays. Through the synchronous action of this multi-stage buffer structure, the impact amplitude of the mixing tank 9 caused by uneven ground or changes in traction speed can be significantly reduced. This design not only reduces the overall vibration and shaking of the equipment, but also extends the service life of key components. At the same time, the shock absorption can also prevent the liquid from overflowing or foaming due to violent shaking during transportation or movement, and maintain the stability of the liquid in the tank. In addition, by setting the traction frame 1 and traction hole 4, the operator can easily move the mixing mixer without the aid of large handling equipment, which greatly improves the flexibility and convenience of the equipment.

Rotating blocks 54 are fixedly connected to both sides of the rotating shaft 53. Stirring blades 55 are fixedly connected to the outer periphery of both rotating blocks 54. The stirring blades 55 facilitate the mixing of the medicine and water. Connecting rods 56 are fixedly connected to both sides of the rotating shaft 53. Scrapers 57 are fixedly connected to the outer sides of multiple connecting rods 56. The scrapers 57 facilitate the scraping of the medicine liquid from the inner wall of the mixing tank 9. The two scrapers 57 are in contact with the inner wall of the mixing tank 9. A fixing block 48 is fixedly connected to the outer left side of the mixing tank 9. The motor 49 is fixedly connected inside the fixing block 48. The fixing block 48 facilitates the fixing of the motor 49.

[0055] Specifically, during the mixing process, the operator first adds the rice blast control agent into the mixing tank 9 through the dosing port 10. After the agent is added, the suction end of the connecting pipe 13 is placed in a clean water source to ensure the water is clean and free of impurities, preventing contamination of the mixture. Then, the water pump 11 is started. Once the pump is operational, it draws in external water through the connecting pipe 13 and steadily delivers the water to the mixing tank 9 along the delivery pipe 12. As water flows in, the liquid level inside the tank gradually rises, providing a sufficient liquid environment for the dissolution of the agent. After the agent and water are fully injected into the tank, the motor 49 is started. When the motor 49 operates, its output end drives the fixedly connected drive wheel 50 to rotate. The driving wheel 50 is connected to the driven wheel 51 via the transmission belt 52 to form a power transmission relationship. Driven by the transmission belt 52, the driven wheel 51 rotates synchronously. As the driven wheel 51 rotates, the internally fixed rotating shaft 53 starts to rotate. During the rotation, the rotating shaft 53 drives the rotating blocks 54 fixed on both sides to rotate synchronously. Several stirring blades 55 are evenly distributed and fixed on the outside of the rotating blocks 54. The stirring blades 55 rotate at high speed in the tank, forming strong fluid disturbance and shearing action, so that the agent and water are fully mixed and quickly dispersed, thereby achieving uniform fusion of the agent solution. The angle and layout of the stirring blades 55 are optimized to maintain a high-efficiency stirring effect at different liquid levels, avoiding agent sedimentation or uneven suspension.

[0056] Working principle: When installing the filter shell 15 outside the drain port 16 of the mixer, firstly, the two moving blocks 25 move relative to each other. The movement of the two moving blocks 25 causes the two arc-shaped blocks 24 fixedly connected at the bottom to move relative to each other. The relative movement of the two arc-shaped blocks 24 compresses the first return spring 27 fixedly connected in the middle, causing the first return spring 27 to deform under force. Then, when the two arc-shaped blocks 24 move relative to each other, the two locking blocks 26 fixedly connected at the top move synchronously, so that the two locking blocks 26 can be removed from the holes opened on both sides inside the mounting ring 23. Then, the two protrusions 19 fixedly connected to the left side of the filter shell 15 are inserted into the inside sides of the mounting ring 23 fixedly connected to the bottom of the drain port 16. Then, under the reaction force of the first return spring 27, the two moving blocks 25 are released, causing the two arc-shaped blocks 24 to return to their original position, and the two locking blocks 26 are inserted into the slots 20 opened inside the two protrusions 19. The installation of the filter shell 15 is then completed. When discharging the liquid, the liquid will enter through the outlet 14. Inside the filter housing 15, the pesticide solution entering the filter housing 15 first undergoes preliminary filtration through the coarse filter plate 21, which filters out larger particles in the pesticide solution. Then, it passes through the fine filter plate 22 to filter out smaller particles. Finally, the filtered pesticide solution is discharged through the drain port 16. When cleaning the coarse filter plate 21 and the fine filter plate 22, the right-side filter housing 15 is rotated to disengage it from the mounting groove 18 inside the connecting ring 61. Then, the connecting ring 61 is rotated again to disengage it from the outside of the left-side filter housing 15. This completes the disassembly and cleaning of the coarse filter plate 21 and the fine filter plate 22. During installation, the disassembly steps are repeated in reverse. This facilitates the filtration of the mixed pesticide solution when the pesticide is discharged from the mixing and stirring machine used for rice blast control. It also facilitates the disassembly, cleaning, and maintenance of the filter equipment. It effectively removes undissolved powder, impurities, or clumps, improving the purity of the pesticide, ensuring uniform spraying, and enhancing the control effect.

[0057] When using solid pesticide for rice blast control, firstly, press down on the two baffle plates 30. The two baffle plates 30 rotate and move downwards outside the two rotating rods 29. As the two baffle plates 30 move downwards, they press down on the two arc-shaped rods 31, which move inside the two through holes 32. As the two arc-shaped rods 31 move, they press down on the two externally sleeved second return springs 39, causing the two second return springs 39 to deform under force. Then, stop pressing when the two baffle plates 30 are exposed inside the hopper 28. Next, pour the solid pesticide for rice blast control into the hopper 28. After the solid pesticide for rice blast control has been added, release the two baffle plates 30. Under the reaction force of the two second return springs 39, the two baffle plates 30 return to their original positions and cover the hopper 28. At this time, start the motor 35, which drives the front transmission rod 36 fixedly connected to the output end to rotate. The rotation of the transmission rod 36 drives the front gear 37, which is fixedly connected to the left side, to rotate. The rotation of the front gear 37 drives the rear gear 37, which is meshed with the rear gear, to rotate. The rotation of the rear gear 37 drives the rear transmission rod 36, which is fixedly connected internally, to rotate. The rotation of the two transmission rods 36 drives the two dispersing rollers 38, which are fixedly connected externally, to rotate. The rotation of the two dispersing rollers 38 can disperse the solid pesticide for rice blast control to prevent clumping. Finally, the dispersed solid pesticide for rice blast control falls into the mixing tank 9. This makes it easy to disperse clumped solid pesticide for rice blast control, so that the pesticide can be fully dissolved or evenly dispersed in water, ensuring a consistent pesticide concentration. At the same time, the dispersing process can also shield the hopper 28 to prevent pesticide powder from floating in the air and causing waste, thereby improving the overall effect of rice blast control.

[0058] During the process of moving the rice blast control agent mixing machine, the traction hole 4 on the left side of the traction frame 1 is first connected to the traction tool. Then, during the movement, when the mixing tank 9 shakes, two rubber arc plates 60 protect the body of the mixing tank 9 to prevent it from shaking left and right. When it shakes up and down, the damper 42 contracts and moves the four buffer rods 45 in all directions. When the four buffer rods 45 move in all directions, they compress the four buffer springs 44 sleeved on the outside of the four guide rods 43. The four buffer springs 44 deform under the force and absorb the shaking force generated by the up and down of the mixing tank 9. This makes it easy to move the rice blast control agent mixing machine by setting the traction frame 1 and the traction hole 4. At the same time, it is easy to absorb the shaking force generated by the mixing tank 9 during the movement, reducing the overall vibration and impact of the equipment, preventing the welds, supports or tank body from loosening or deforming due to long-term bumps, and improving the convenience of moving the equipment.

[0059] When mixing the chemicals, firstly, add the chemicals into the mixing tank 9 through the dosing port 10. Then, place the connecting pipe 13 into the water source. Next, start the water pump 11 to draw water into the water source through the connecting pipe 13, and then transport it into the mixing tank 9 through the delivery pipe 12. Then, start the motor 49. The motor 49 drives the drive wheel 50, which is fixedly connected to the output end, to rotate. The rotation of the drive wheel 50 drives the driven wheel 51 to rotate through the transmission belt 52. The rotation of the driven wheel 51 drives the rotating shaft 53, which is fixedly connected inside, to rotate. The rotation of the rotating shaft 53 drives the rotating blocks 54, which are fixedly connected to both sides outside, to rotate. The rotation of the rotating blocks 54 drives the external... The stirring blades 55, fixedly connected on all four sides, rotate, mixing the pesticide and water. As the rotating shaft 53 rotates, it also drives the connecting rods 56, fixedly connected to both sides, to rotate. The rotating connecting rods 56, in turn, drive the externally fixed scraper 57 to rotate, scraping away the pesticide residue adhering to the inner wall of the mixing tank 9. This process ensures thorough mixing of the pesticide inside the mixing tank 9 while simultaneously removing any residue adhering to the inner wall. Timely removal of residual pesticide prevents it from drying out or deteriorating, thus protecting the quality of the next batch and ensuring the purity and effectiveness of the pesticide.
