Description

Technical Field

[0001] This application relates to the technical field of herbicide production, and in particular to a production apparatus for herbicide synthesis. Background Technology

[0002] Herbicides are highly effective, broad-spectrum, and systemic benzothiazole herbicides. This compound can exert its weed-controlling effect through various application methods, including foliar spraying, seed coating, and soil treatment. In industrial production, its synthesis reaction must be completed in a reactor equipped with production equipment.

[0003] Currently, typical herbicide production equipment involves adding the herbicide technical material and reaction medium into a stirred tank, then using a motor to drive the stirring shaft and rotate the impeller to achieve mechanical mixing and mass transfer of the materials, ultimately synthesizing the target product.

[0004] However, corrosive substances are generated during the production process, which can easily damage the agitator shaft, requiring frequent equipment maintenance and increasing production costs. Summary of the Invention

[0005] In order to reduce the production cost of herbicide synthesis, this application provides a production apparatus for herbicide synthesis.

[0006] This application provides a production apparatus for the synthesis of herbicides, which adopts the following technical solution:

[0007] A production apparatus for synthesizing herbicides includes a reactor, a drive mechanism, and at least one stirring mechanism. The reactor has an inlet pipe at its top and an outlet pipe at its bottom. The reactor contains a mixture of herbicides technical and a reaction medium. A control valve is installed on the outlet pipe. The drive mechanism is mounted on the reactor and drives the stirring mechanism to rotate. The at least one stirring mechanism includes a base, at least one set of stirring teeth, a power component, and a stirring assembly. The base is rotatably mounted inside the reactor. At least one set of stirring teeth is mounted on the base, with multiple teeth arranged along the radius of the base's rotation circumference. One end of the power component is connected to the base, and the other end contacts the inner wall of the reactor. The stirring assembly is rotatably mounted on the base. When the base rotates, the reactor provides force to the power component, causing the power component to drive the stirring assembly to rotate, thus stirring the mixture around the stirring teeth and preventing corrosive substances in the mixture from adhering to the stirring teeth.

[0008] Optionally, the drive mechanism includes a driver, a drive gear, a driven gear, and a support cylinder. The driver is fixedly connected to the reactor; the drive gear is connected to the driver; the driven gear meshes with the drive gear; the support cylinder is disposed inside the reactor and is coaxially fixedly connected to the driven gear, wherein the support cylinder rotates under the meshing action of the drive gear and the driven gear.

[0009] Optionally, the stirring mechanism is configured as multiple groups, with multiple groups of stirring mechanisms arranged around the axis of the support cylinder, and each group of stirring mechanisms having multiple stirring mechanisms arranged along the axial direction of the support cylinder.

[0010] Optionally, the number of power components corresponds to the number of stirring mechanisms. The power components include a vertical rod, at least one roller, and a first bevel gear. The vertical rod is connected to the base component via an extension and is located between the base component and the inner wall of the reactor. At least one roller is coaxially fixedly connected to the vertical rod and contacts the inner wall of the reactor, rotating along the inner wall of the reactor. The first bevel gear is coaxially fixedly connected to the vertical rod, and the diameter of the roller is larger than the diameter of the first bevel gear. The base component is hollow inside, and the first bevel gear meshes with a second bevel gear. The second bevel gear is coaxially fixedly connected to a rotating rod, one end of which rotatably passes through the base component.

[0011] Optionally, the stirring assembly includes a driving bevel gear and at least one driven bevel gear. The driving bevel gear is coaxially fixedly connected to the rotating rod and located within the base component. At least one driven bevel gear meshes with the driving bevel gear. A connecting rod is coaxially fixedly connected to the driven bevel gear. The connecting rod passes through the base component. An stirring wheel is fixedly connected to the end of the connecting rod away from the driven bevel gear. The stirring wheel is located on one side of the stirring teeth.

[0012] Optionally, the production apparatus also includes a detection mechanism, which comprises an electric telescopic rod, a controller, a bottom cylinder, and a detection component. The electric telescopic rod is mounted on the top of the support cylinder, with its fixed end fixedly connected to the top of the reactor, and its movable end located inside the support cylinder. The controller is mounted on the reactor, and both the electric telescopic rod and the actuator are electrically connected to the controller. The controller is used to control the extension or retraction of the movable end of the electric telescopic rod and to control the start and stop of the actuator. The top of the bottom cylinder is open, and the open end has a rotating groove. The bottom end of the support cylinder is rotatably mounted in the rotating groove, and the bottom end of the bottom cylinder is fixedly connected to the bottom end of the reactor. The bottom cylinder has multiple through holes arranged around its axis. The detection component is located inside the support cylinder and is used to detect the concentration of the herbicide.

[0013] Optionally, the detection component includes a concentration detection sensor and a float. The concentration detection sensor is embedded in a preset detection position on the support cylinder and is used to detect the concentration of the herbicide. The concentration detection sensor outputs a concentration signal and is electrically connected to the controller. The controller responds to the concentration signal output by the concentration detection sensor. The float is slidably connected inside the support cylinder, and the sliding direction is the axial direction of the support cylinder. The float contacts the movable end of the electric telescopic rod.

[0014] Optionally, the detection assembly also includes a float, which is fixedly connected to the end of the float plate away from the motorized telescopic rod.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] This application can drive the stirring mechanism to rotate around the vertical axis of the reactor via a drive mechanism. During the rotation, the base component drives the stirring teeth to stir the mixture, so that the mixture reacts fully to synthesize the herbicide. At the same time, since the power component is in contact with the inner wall of the reactor, the inner wall of the reactor provides friction for the power component, so that the power component drives the stirring component to rotate, so that the stirring component can synchronously disperse the mixture around the stirring teeth, making it difficult for corrosive substances in the mixture to adhere to the stirring teeth, effectively preventing the stirring teeth from being corroded, thereby effectively reducing production costs.

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses a production apparatus for the synthesis of herbicides. Figure 1 A schematic diagram of the production apparatus according to an embodiment of this application is shown; Figure 2 A cross-sectional schematic diagram of a production apparatus according to an embodiment of this application is shown; Figure 3 yes Figure 2 Enlarged view at point A in the middle; Figure 4 yes Figure 2 Enlarged view at point B; Figure 5 yes Figure 2 A magnified view of point C in the middle.

[0035] According to the example embodiment, refer to Figures 1-4 A production apparatus for synthesizing herbicides includes a reactor 1, a drive mechanism 2, and a stirring mechanism 3. The reactor 1 has an inlet pipe 11 and an outlet pipe 13 at its top and bottom, respectively. The reactor 1 contains a mixture formed from herbicides technical and a reaction medium. A control valve 14 is installed on the outlet pipe 13.

[0036] For example, the reactor 1 can be a cylindrical structure or a conical structure. The reactor 1 can be erected on the ground by a profile frame or supported on the ground by support columns 12. The feed pipe 11 can be a straight pipe structure or a flared structure. The discharge pipe 13 is a straight pipe structure. The control valve 14 can be, but is not limited to, a solenoid valve or a ball valve.

[0037] For example, refer to Figure 1The reactor 1 is cylindrical and vertically positioned. The feed pipe 11 is vertically positioned, with one end connected to the top of the reactor 1. Four support columns 12 are provided, evenly arranged around the vertical axis of the reactor 1. The support columns 12 are cylindrical and vertically positioned.

[0038] The discharge pipe 13 is a straight pipe structure, vertically arranged, with its top end connected to the bottom end of the reactor 1. A solenoid valve is installed on the discharge pipe 13.

[0039] According to the example embodiment, refer to Figure 2 and Figure 3 At least one stirring mechanism 3 includes a base component 31, at least one set of stirring teeth 32, a power component 33, and a stirring component 34. The base component 31 is rotatably disposed inside the reactor 1. At least one set of stirring teeth 32 is disposed on the base component 31, and each set of stirring teeth 32 is provided with multiple teeth, which are arranged along the radial direction of the rotation circumference of the base component 31.

[0040] For example, the base component 31 can be a plate-like structure or a column-like structure. The base component 31 can be made of corrosion-resistant materials, including but not limited to 316L stainless steel, 2205 duplex steel, polytetrafluoroethylene (PTFE) coating, or carbon fiber reinforced resin. The stirring teeth 32 can be configured in multiple sets, and the multiple sets of stirring teeth 32 can be symmetrically arranged on the base component 31.

[0041] For example, the base component 31 is a rectangular plate structure, vertically arranged, with its width direction parallel to the vertical axis of the reactor 1. The base component 31 can be made of 316L stainless steel, and the stirring teeth 32 are configured in two sets, symmetrically arranged at the top and bottom ends of the base component 31. Each set of stirring teeth 32 consists of multiple teeth, which are evenly distributed along the length of the base component 31.

[0042] According to the example embodiment, refer to Figure 2 and Figure 3 One end of the power assembly 33 is connected to the base component 31, and the other end contacts the inner wall of the reactor 1. The stirring assembly 34 is rotatably mounted on the base component 31. When the base component 31 rotates, the reactor 1 provides force to the power assembly 33, causing the power assembly 33 to drive the stirring assembly 34 to rotate, thereby stirring the mixture around the stirring teeth 32 and preventing corrosive substances in the mixture from adhering to the stirring teeth 32. The drive mechanism 2 is mounted on the reactor 1 and is used to drive the stirring mechanism 34 to rotate.

[0043] For example, the power assembly 33 is located between the base 31 and the inner wall of the reactor 1, with one end connected to the base 31 and the other end in contact with the inner wall of the reactor 1. The stirring assembly 34 is rotatably mounted on the base 31, and the drive mechanism 2 is mounted on the reactor 1 and is used to drive the stirring mechanism 34 to rotate.

[0044] When the driving mechanism 2 drives the stirring mechanism 3 to rotate, the inner wall of the reactor 1 provides friction to the power component 33, so that the power component 33 drives the stirring component 34 to rotate, thereby stirring the mixture around the stirring teeth 32, so that corrosive substances in the mixture (such as chloride-containing deposits) are not easily attached to the stirring teeth 32.

[0045] Through the above embodiments, the driving mechanism 2 drives the stirring mechanism 3 to rotate around the vertical axis of the reactor 1. During the rotation, the base component 31 drives the stirring teeth 32 to stir the mixture, so that the mixture reacts fully to synthesize herbicide.

[0046] Meanwhile, since the power component 33 is in contact with the inner wall of the reactor 1, the inner wall of the reactor 1 provides friction for the power component 33, which drives the stirring component 34 to rotate, so as to stir the mixture around the stirring teeth 32. This makes it difficult for corrosive substances in the mixture to adhere to the stirring teeth 32, thereby effectively reducing production costs.

[0047] According to the example embodiment, refer to Figure 1 and Figure 4 The drive mechanism 2 includes a driver 21, a driving gear 22, a driven gear 23, and a support cylinder 24. The driver 21 is fixedly connected to the reactor 1. The driving gear 22 is connected to the driver 21, and the driven gear 23 meshes with the driving gear 22. The support cylinder 24 is disposed inside the reactor 1 and is coaxially fixedly connected to the driven gear 23. Under the meshing action of the driving gear 22 and the driven gear 23, the support cylinder 24 rotates.

[0048] For example, the driver 21 may be, but is not limited to, a servo motor, an asynchronous motor, a hydraulic motor, or a pneumatic motor, and the driver 21 may be used in conjunction with a reducer. The support cylinder 24 may be made of corrosion-resistant material, which may include, but is not limited to, 316L stainless steel or 2205 duplex steel.

[0049] The two ends of the support cylinder 24 can be open, and the two open ends are rotatably connected to the reactor 1 through a limiting groove. A sealing ring can be set in the limiting groove to prevent the mixture from entering the support cylinder 24. The two ends of the support cylinder 24 can also be sealed. A rotating groove is set on the support cylinder 24, and a fixing ring is set on the reactor 1. The fixing ring is located in the rotating groove to limit the support cylinder 24.

[0050] For example, the driver 21 can be a servo motor, fixedly connected to the top of the reactor 1 and located on one side of the feed pipe 11, with the output shaft of the servo motor located inside the reactor 1. The driving gear 22 and the output shaft of the servo motor can be connected via a keyway (not shown in the figure). The driven gear 23 meshes with the driving gear 22 and is coaxially fixedly connected to the top of the support cylinder 24. The support cylinder 24 is cylindrical and vertically arranged. Both ends of the support cylinder 24 can be open, and the two open ends are rotatably connected to the reactor 1 via a limiting groove (not shown in the figure).

[0051] Through the above embodiments, this application starts a servo motor, the output shaft of the servo motor drives the drive gear 22 to rotate, the drive gear 22 drives the driven gear 23 to rotate, the driven gear 23 drives the support cylinder 24 to rotate, the support cylinder 24 drives the base component 31 to rotate, and the base component 31 drives the stirring teeth 32 to stir the mixture, so that the mixture reacts fully to synthesize the herbicide, thereby improving the production quality of the herbicide.

[0052] According to the example embodiment, refer to Figure 2 and Figure 3 The stirring mechanism 3 is configured as multiple groups, and the multiple groups of stirring mechanisms 3 are arranged around the axis of the support cylinder 24. Each group of stirring mechanisms 3 is provided with multiple stirring mechanisms 3, and the multiple stirring mechanisms 3 are arranged along the axis of the support cylinder 24.

[0053] For example, refer to Figure 2 The stirring mechanism 3 is provided in four groups. The four groups of stirring mechanisms 3 are evenly arranged around the axis of the support cylinder 24. Each group of stirring mechanisms 3 is provided with four stirring mechanisms 3. The four stirring mechanisms 3 are evenly arranged along the vertical axis of the support cylinder 24.

[0054] Through the above embodiments, this application increases the number of stirring mechanisms 3, and when the support cylinder 24 rotates, the axial arrangement makes the mixture form a spiral convection in the vertical direction, which can avoid stratification; the circumferential uniform distribution can ensure that the reactor 1 is subjected to uniform shear force at each point on the cross-section, eliminate the stirring dead zone, thereby improving the stirring effect and thus improving the production quality of the herbicide.

[0055] According to the example embodiment, refer to Figure 2 and Figure 3 The number of power components 33 corresponds to the number of stirring mechanisms 3. The power components 33 include a vertical rod 330, at least one roller 331 and a first bevel gear 332. The vertical rod 330 is connected to the base component 31 through an extension 311 and is located between the base component 31 and the inner wall of the reactor 1.

[0056] For example, the extension 311 can be a pair of plate-like structures, respectively fixedly connected to both ends of the base 31 in the width direction. The extension 311 is horizontally arranged, and a vertical plate 312 can be provided on the extension 311. One side of the vertical plate 312 contacts the inner wall of the reactor 1. The two ends of the vertical rod 330 are rotatably connected to the pair of plate-like structures.

[0057] The extension 311 can also be a rectangular funnel-shaped structure, with the constricted end fixedly connected to the end of the base 31, and the flared end able to contact the inner wall of the reactor 1. The vertical rod 330 is located inside the rectangular funnel-shaped structure.

[0058] For example, the vertical rod 330 can be a round rod structure, and the extension 311 can be a pair of plate-shaped structures, which are respectively fixedly connected to the two ends of the base 31 in the width direction. The two ends of the vertical rod 330 are rotatably connected to the extension 311 through a slot (not shown in the figure). The extension 311 is set horizontally, and a vertical plate 312 can be set on the extension 311. One side of the vertical plate 312 is in contact with the inner wall of the reactor 1.

[0059] According to the example embodiment, refer to Figure 3 At least one roller 331 is coaxially and fixedly connected to the vertical rod 330 and contacts the inner wall of the reactor 1. The roller 331 rotates along the inner wall of the reactor 1. The first bevel gear 332 is coaxially and fixedly connected to the vertical rod 330. The diameter of the roller 331 is larger than the diameter of the first bevel gear 332.

[0060] For example, multiple rollers 331 can be provided, and the multiple rollers 331 are evenly arranged along the axial direction of the vertical rod 330.

[0061] For example, refer to Figure 3 Two rollers 331 are provided, and the two rollers 331 are evenly arranged along the axial direction of the vertical rod 330. The rollers 331 are in rolling friction contact with the inner wall of the reactor 1. The first bevel gear 332 is coaxially fixedly connected to the vertical rod 330 and is located between the two rollers 331. The diameter of the rollers 331 is larger than the diameter of the first bevel gear 332.

[0062] According to the example embodiment, refer to Figure 3 The base component 31 is hollow inside. The first bevel gear 332 meshes with the second bevel gear 333. The second bevel gear 333 is coaxially fixedly connected to the rotating rod 334. One end of the rotating rod 334 is rotatably inserted through the base component 31.

[0063] For example, the base component 31 is hollow inside, the first bevel gear 332 meshes with the second bevel gear 333, the second bevel gear 333 is coaxially fixedly connected to the rotating rod 334, the rotating rod 334 is in the shape of a circular rod, the axis of the rotating rod 334 is parallel to the length direction of the rectangular plate structure of the base component 31, and one end of the rotating rod 334 is rotatably inserted through the base component 31.

[0064] According to the example embodiment, the stirring assembly 34 includes an active bevel gear 341 and at least one driven bevel gear 342. The active bevel gear 341 is coaxially fixedly connected to the rotating rod 334 and located inside the base (31). At least one driven bevel gear 342 meshes with the active bevel gear 341.

[0065] For example, the stirring assembly 34 can be configured as multiple sets, and the multiple sets of stirring assemblies 34 are arranged along the rotating rod 334. The driven bevel gear 342 can be configured as multiple sets, and the multiple driven bevel gears 342 are configured in one-to-one correspondence with the multiple sets of stirring teeth 32.

[0066] For example, refer to Figure 3 The stirring assembly 34 can be configured as two sets, and the two sets of stirring assemblies 34 are evenly arranged along the rotating rod 334. There are two driven bevel gears 342, which are fixedly connected to the rotating rod 334 by a flat key (not shown in the figure) and mesh with the driving bevel gear 341.

[0067] According to the example embodiment, refer to Figure 3 A connecting rod 343 is coaxially fixedly connected to the driven bevel gear 342. The connecting rod 343 passes through the base component 31. An agitator 344 is fixedly connected to the end of the connecting rod 343 away from the driven bevel gear 342. The agitator 344 is located on one side of the agitator 32.

[0068] For example, refer to Figure 3 The connecting rod 343 is in the shape of a circular rod. The driven bevel gear 342 and the connecting rod 343 can be fixedly connected by a flat key (not shown in the figure). The top end of the connecting rod 343 passes through the base component 31. The stirring wheel 344 and the connecting rod 343 can be fixedly connected by a flat key (not shown in the figure). The stirring wheel 344 is located on the side of the stirring tooth 32 away from the base component 31.

[0070] Under the action of friction on the inner wall of the reactor 1, the roller 331 drives the first bevel gear 332 to rotate, the first bevel gear 332 drives the second bevel gear 333 to rotate, the second bevel gear 333 drives the rotating rod 334 to rotate, the rotating rod 334 drives the driving bevel gear 341 to rotate, the driving bevel gear 341 drives the driven bevel gear 342 to rotate, and the driven bevel gear 342 drives the stirring wheel 344 to rotate, so that the stirring wheel 344 can stir the mixture around the stirring teeth 32, making it difficult for corrosive substances in the mixture to adhere to the stirring teeth 32, preventing the stirring teeth 32 from corroding, thereby effectively reducing production costs;

[0071] In addition, this application can also achieve multi-directional stirring in the reactor 1 by means of the stirring wheel 344, thereby expanding the stirring range and making it easier to obtain a more uniform mixture of herbicides.

[0072] According to the example embodiment, refer to Figures 2-5 The production device also includes a detection mechanism 4, which includes an electric telescopic rod 41, a controller 42, a bottom cylinder 43, and a detection component 44. The electric telescopic rod 41 is set on the top of the support cylinder 24, with its fixed end fixedly connected to the top of the reactor 1 and its movable end set inside the support cylinder 24.

[0073] For example, the fixed end of the electric telescopic rod 41 can be fixedly connected to the top of the reactor 1 by means including but not limited to flange connection or welding.

[0074] For example, the support cylinder 24 is open at both ends, the fixed end of the electric telescopic rod 41 can be welded to the center of the top of the reactor 1, the inner wall of the top opening of the support cylinder 24 and the outer wall of the electric telescopic rod 41 can contact each other through a sealing ring (not shown in the figure), and the movable end of the electric telescopic rod 41 is disposed inside the support cylinder 24.

[0075] According to the example embodiment, refer to Figure 4 The controller 42 is installed on the reactor 1. The electric telescopic rod 41 and the driver 21 are both electrically connected to the controller 42. The controller 42 is used to control the extension or retraction of the movable end of the electric telescopic rod 41 and to control the start and stop of the driver 21.

[0076] For example, refer to Figure 4 The controller 42 is fixedly connected to the electric telescopic pole 41. Specifically, it can be fixed to the sleeve housing of the electric telescopic pole 41 by bolts, and its signal line is led out through a waterproof connector. The controller 42 is located inside the sleeve 41. Both the electric telescopic pole 41 and the driver 21 are electrically connected to the controller 42. The controller 42 is used to control the extension or retraction of the movable end of the electric telescopic pole 41 and to control the start and stop of the driver 21.

[0077] According to the example embodiment, refer to Figure 2 The bottom cylinder 43 has an open top and a rotating groove 431 at the open end. The bottom end of the support cylinder 24 is rotatably disposed in the rotating groove 431. The bottom end of the bottom cylinder 43 is fixedly connected to the bottom end of the reactor 1. The bottom cylinder 43 has multiple through holes 432, which are arranged around the axis of the bottom cylinder 43.

[0078] For example, refer to Figure 2 The bottom cylinder 43 has a cylindrical structure with an open top and a rotating groove 431 at the open end. The bottom end of the support cylinder 24 is rotatably mounted in the rotating groove 431. The bottom end of the bottom cylinder 43 is welded to the bottom end of the reactor 1. The bottom cylinder 43 has multiple through holes 432, which are evenly arranged around the axis of the bottom cylinder 43.

[0079] According to the example embodiment, refer to Figure 2 and Figure 5 The detection component 44 is disposed within the support cylinder 24 and is used to detect the concentration of herbicide. The detection component 44 includes a concentration detection sensor 441, a float 442, and a float ball 443. The concentration detection sensor 441 is embedded in a preset detection position in the support cylinder 24 and is used to detect the concentration of herbicide. The concentration detection sensor 441 outputs a concentration signal. Both the concentration detection sensor 441 and the control valve 14 are electrically connected to the controller 42, and the controller 42 responds to the concentration signal output by the concentration detection sensor 441.

[0080] For example, it should be noted that the preset detection position is close to the electric telescopic rod 41, allowing sufficient reaction time for the mixture, and the reaction time is fed back by the height of the support cylinder 24.

[0081] For example, refer to Figure 2 and Figure 5 The concentration detection sensor 441 is embedded in the preset detection position of the support cylinder 24 and is used to detect the concentration of herbicide. The concentration detection sensor 441 outputs a concentration signal. The concentration detection sensor 441 and the solenoid valve are both electrically connected to the controller 42. The controller 42 responds to the concentration signal output by the concentration detection sensor 441.

[0082] According to the example embodiment, refer to Figure 2 and Figure 5 The float plate 442 is slidably connected inside the support cylinder 24, and the sliding direction is the axial direction of the support cylinder 24. The float plate 442 is in contact with the movable end of the electric telescopic rod 41.

[0083] For example, the outer periphery of the float plate 442 contacts the inner wall of the support cylinder 24, and the center of its top surface contacts the movable end of the electric telescopic rod 41. The float plate 442 is slidably connected inside the support cylinder 24, and the sliding direction is the axial direction of the support cylinder 24.

[0084] Through the above embodiments, the mixture can enter the support cylinder 24 through the through hole 432. Under the action of buoyancy, the float plate 442 moves to above the preset detection position, and the concentration detection sensor 441 detects the concentration of the mixture.

[0085] When the concentration of the mixture does not reach the set value, the concentration detection sensor 441 outputs a concentration signal. In response to the concentration signal output by the concentration detection sensor 441, the controller 42 controls the movable end of the electric telescopic rod 41 to move. The movable end of the electric telescopic rod 41 pushes the float 442 to reset, and the movable end of the electric telescopic rod 41 retracts to reset. The float 442 squeezes the mixture out of the support cylinder 24, so that the mixture continues to react and synthesize the herbicide.

[0086] When the concentration of the mixture reaches the set value, the controller 42 controls the solenoid valve to open, thereby removing the herbicide from the reactor 1. After the pressure is released, the float 442 resets under its own gravity. This application can easily improve the efficiency of automated production by monitoring the concentration change of the herbicide in real time.

[0087] According to the example embodiment, refer to Figure 5 The detection component 44 also includes a float 443, which is fixedly connected to the end of the float plate 442 away from the electric telescopic rod 41.

[0088] For example, the float 443 is attached to the end of the float plate 442 away from the electric telescopic rod 41.

[0089] Through the above embodiments, this application can cause the float 443 to drive the float plate 442 to move under the buoyancy of the mixture. By adding the float 443, the buoyancy is increased, making it easier to monitor the concentration change of the herbicide.

[0090] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
