Description

Technical Field

[0001] This invention belongs to the technical field of agricultural pest control equipment, and relates to a green control spraying device for agricultural pests and diseases. Background Technology

[0002] Agricultural pest control refers to the monitoring, early warning, and control of harmful insects, fungi, viruses, and other organisms in agricultural production through a series of scientific and technological means, in order to reduce their harm to crops and ensure agricultural production and the quality and safety of agricultural products. Among them, green control is an important means of agricultural pest control. It emphasizes the use of environmentally friendly measures such as ecological control, biological control, physical control, and scientific pesticide application to control harmful organisms, protect the ecological environment, and improve the quality and safety level of agricultural products.

[0003] Currently, spraying devices are commonly used when using pesticides to control pests and diseases. These devices mainly consist of a tank, a water pump, a nozzle, and a traveling mechanism. The pesticide and water are added into the tank and mixed. The traveling mechanism then moves the tank, along with the water pump and nozzle, across the farmland. During this movement, the water pump extracts the pesticide solution from the tank and sprays it through the nozzle to control pests and diseases.

[0004] However, since pesticides are divided into wettable powders, liquids, etc., directly adding different types of pesticides into the container and mixing them with water can easily cause wettable powders to agglomerate, resulting in uneven dispersion of different pesticides in the water and affecting the effectiveness of pesticide use. Summary of the Invention

[0005] The purpose of this invention is to provide a green pesticide spraying device for the prevention and control of agricultural pests and diseases, which can reduce the agglomeration force between wettable powder particles, thereby reducing the agglomeration of wettable powder and making different pesticides more evenly dispersed in water.

[0006] To achieve the above objectives, the present invention provides a specific technical solution for a green pest control spraying device for agricultural diseases and pests as follows:

[0007] A green spraying device for agricultural pest and disease control includes a housing, a first stirring mechanism inside the housing for rotating and stirring the liquid inside the housing, and further includes:

[0008] At least one first tank is vertically installed on the upper part of the box, and a second stirring mechanism is installed inside the first tank;

[0009] The second tank is horizontally arranged on the side of the box and is close to the first tank. The second tank is connected to the first tank through the first one-way conveyor. The end of the second tank away from the box has a through hole, and a piston is installed inside the second tank.

[0010] The nozzle is installed on the inner wall of the box. The nozzle is connected to the second tank through the second one-way conveyor. Multiple output holes are opened on the nozzle away from the inner wall. The angles formed by the multiple output holes and the horizontal direction are different.

[0011] The horizontal reciprocating moving mechanism has an output end, which is connected to a piston. It is used to drive the piston to move horizontally and reciprocally in the second tank, pressurize the mixture in the first tank and inject it into the box, so that the mixture enters the rotating liquid at a certain speed from multiple different angles.

[0012] The invention is further characterized by:

[0013] The horizontal reciprocating moving mechanism includes: a partition plate, horizontally arranged inside the housing, dividing the housing into a driving chamber and a mixing chamber from top to bottom; a connecting shaft, vertically arranged inside the driving chamber and positioned close to the second tank; a cam, horizontally sleeved on the connecting shaft; a push rod, horizontally arranged between the cam and the second tank, with one end of the push rod passing through the inner wall of the mixing chamber and the end of the second tank before connecting to a piston; a moving block, arranged at the other end of the push rod, contacting the edge of the cam; a first elastic element, sleeved on the push rod and located between the moving block and the inner wall of the driving chamber; and a rotating assembly, arranged inside the mixing chamber, used to drive the connecting shaft to rotate.

[0014] A limit groove is horizontally formed at the upper part of the partition near the moving block, and a limit block is set in the limit groove. The upper part of the limit block is connected to the lower part of the moving block.

[0015] The rotating assembly includes: a drive shaft, vertically arranged inside the mixing chamber and positioned close to the connecting shaft, with its lower end rotatably connected to the partition plate and its upper end passing through the top of the mixing chamber and located on the upper part of the housing; a motor, located on the upper part of the housing, with its output end connected to the upper end of the drive shaft; a first gear, sleeved on the drive shaft; and a second gear, sleeved on the connecting shaft and positioned close to the first gear, with the second gear meshing with the first gear.

[0016] The lower end of the drive shaft passes through the partition and is connected to the first stirring mechanism. The connecting shaft is located close to the first tank. The upper end of the connecting shaft passes through the top of the mixing chamber and the lower part of the first tank and is connected to the second stirring mechanism. The connecting shaft is connected to the cam through a clutch assembly. There are multiple connecting shafts, which are evenly arranged around the drive shaft.

[0017] The clutch assembly includes: a first pawl disc, sleeved on and rotatably connected to the connecting shaft, with a cam sleeved on the first pawl disc; a second pawl disc, sleeved on the connecting shaft and located above the first pawl disc, slidably connected to the connecting shaft, with a gap between the second pawl disc and the first pawl disc, and capable of engaging with the first pawl disc after the second pawl disc moves downward; a control rod, the connecting shaft having a hollow internal structure, the control rod being located inside the connecting shaft, with its upper end passing through the upper end and inlet of the connecting shaft and located outside the first tank body; and a connecting piece, connected to the control rod and the second pawl disc respectively, used to drive the second pawl disc to move up and down via the control rod.

[0018] The first one-way conveying component includes: a first connecting pipe disposed between the second tank and the first tank, one end of the first connecting pipe being connected to the first tank and the other end of the first connecting pipe being connected to the second tank, with the connection position located between the piston and the housing; and a first one-way valve disposed on the first connecting pipe.

[0019] The second one-way conveying component includes: a second connecting pipe, which is disposed between the second tank and the nozzle, with one end of the second connecting pipe connected to the second tank and the other end of the second connecting pipe passing through the side wall of the tank and connected to the nozzle; and a second one-way valve, which is disposed on the second connecting pipe.

[0020] The second check valve is a one-way pressure relief valve.

[0021] The green pest and disease control spraying device of the present invention has the following advantages:

[0022] First, through the cooperation of a first stirring mechanism, at least one first tank, a second stirring mechanism, a second tank, a piston, a nozzle, multiple output holes, and a horizontal reciprocating moving mechanism, the pesticide and water added to the first tank can be initially stirred and mixed by the second stirring mechanism, so that the pesticide is first mixed with a small amount of water to form a relatively uniform mixture, ensuring that wettable powders and other pesticides are fully dispersed in the water. The horizontal reciprocating moving mechanism drives the piston to move, causing the internal pressure of the second tank to change, pressurizing the mixture and injecting it into the tank. The mixture enters the rotating liquid at a certain speed from multiple different angles, so that the mixture can form local eddies at different positions in the rotating liquid, promoting the formation of turbulence, enhancing the diffusion ability of pesticides, breaking the interface between pesticides and water, reducing the agglomeration force between wettable powder particles, thereby reducing the agglomeration of wettable powders and making different pesticides more evenly dispersed in water.

[0023] Secondly, through the cooperation of multiple connecting shafts, multiple first tanks and multiple clutch components, multiple different pesticides can be mixed sequentially. After multiple different pesticides are added to the tank, air can be injected into the tank at a certain speed from multiple different angles, so that the mixture in the tank forms local vortices at multiple different positions, further promoting the reduction of agglomeration force between wettable powder particles.

[0034] The technical solutions of this application will now be described clearly and in detail with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " indicates "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more. The terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0035] like Figure 1 , Figure 2As shown, this invention provides a green pest control spraying device for agricultural diseases and pests, including a housing 1, a first stirring mechanism, at least one first tank 4, a second stirring mechanism, a second tank 5, a nozzle 37, a piston 15, and a horizontal reciprocating movement mechanism. The housing 1 is equipped with a first stirring mechanism, which is used to rotate and stir the liquid inside the housing 1. Initially, a large amount of water is added to the housing 1, and the first stirring mechanism stirs the water, causing it to rotate. At least one first tank 4 is vertically arranged on the upper part of the housing 1. The first tank 4 is equipped with a second stirring mechanism, which is used to initially stir and mix the pesticide and water added to the first tank 4, that is, the pesticide and a small amount of water are mixed first to form a relatively uniform mixture, ensuring the wettable powder... The pesticides, such as wettable powders, are fully dispersed in the water, avoiding the possibility of excessively high local concentrations when adding wettable powders directly to large amounts of water, which could cause the wettable powders to agglomerate. The second tank 5 is horizontally positioned on the side of the housing 1, close to the first tank 4, meaning that the second tank 5 corresponds to the first tank 4, with one first tank 4 corresponding to one second tank 5. The second tank 5 and the first tank 4 are connected by a first one-way conveyor, facilitating the unidirectional flow of the pesticide-water mixture in the first tank 4 into the second tank 5. A through hole 23 is provided at the end of the second tank 5 away from the housing 1. A piston 15 is installed inside the second tank 5, with its edge slidingly and sealingly connected to the inner wall of the second tank 5. The through hole 23 allows the piston 15 to move left and right. During movement, external gas enters or exits through the through-hole 23, causing a change in the pressure inside the second tank 5. The nozzle 37 is located on the inner wall of the housing 1, close to the second tank 5. The nozzle 37 is connected to the second tank 5 via a second unidirectional conveying component, facilitating unidirectional entry of the mixture from the second tank 5 into the nozzle 37. Multiple output holes 40 are located away from the inner wall of the nozzle 37, each forming a different angle with the horizontal direction, allowing the mixture to enter the housing 1 at different angles. The horizontal reciprocating movement mechanism has an output end connected to the piston 15, driving the piston 15 to reciprocate horizontally within the second tank 5, causing a change in the pressure inside the second tank 5, thus changing the pressure inside the first tank 5. The mixture in tank 4 is pressurized and injected into box 1, causing it to enter the rotating liquid at a certain speed from multiple different angles. First, piston 15 moves towards through-hole 23, reducing the pressure inside second tank 5 and drawing the mixture from first tank 4 into second tank 5. Then, piston 15 returns to its original position, increasing the pressure inside second tank 5 and pressurizing the mixture. This allows the mixture to enter the rotating liquid at a certain speed, and through multiple outlet holes 40, it enters the rotating liquid at different angles at a constant speed. Local eddies are formed at different positions within the rotating liquid, promoting turbulence, enhancing pesticide diffusion, breaking down the pesticide-water interface, and reducing the agglomeration force between wettable powder particles.This reduces the agglomeration of wettable powders, resulting in more uniform dispersion of different pesticides in water.

[0036] like Figure 2 , Figure 3 , Figure 4 As shown, the horizontal reciprocating moving mechanism includes a partition 14, a connecting shaft 8, a cam 16, a push rod 17, a moving block 20, a first elastic element 18, and a rotating assembly. The partition 14 is horizontally arranged inside the housing 1, and the edge of the partition 14 is fixedly connected to the inner wall of the housing 1, dividing the housing 1 into a driving chamber 141 and a mixing chamber 142 from top to bottom. The second tank 5 is located close to the driving chamber 141 and is unidirectionally connected to the mixing chamber 142, so that the mixture in the second tank 5 flows unidirectionally into the mixing chamber 142. The connecting shaft 8 is vertically arranged inside the driving chamber 141 and is positioned... The lower end of the connecting shaft 8 is rotatably connected to the partition plate 14, and the upper end of the connecting shaft 8 is rotatably connected to the top of the mixing chamber 142. The cam 16 is horizontally sleeved on the connecting shaft 8, and the push rod 17 is horizontally positioned between the cam 16 and the second tank 5. One end of the push rod 17 passes through the inner wall of the mixing chamber 142 and the end of the second tank 5 and is connected to the piston 15. The push rod 17 is slidably sealed to the housing 1 and the second tank 5, so that a sealed cavity is formed in the second tank 5 at the position between the piston 15 and the housing 1, thereby facilitating the movement of the piston 15. As the pressure inside the sealed cavity changes, the moving block 20 is positioned at the other end of the push rod 17. The moving block 20 contacts the edge of the cam 16. Initially, the closest end of the cam 16 contacts the moving block 20, and the lower part of the moving block 20 is slidably connected to the partition plate 14, facilitating the horizontal movement of the moving block 20 by the rotation of the cam 16. The first elastic element 18 is sleeved on the push rod 17 and located between the moving block 20 and the inner wall of the drive cavity 141. The two ends of the first elastic element 18 are respectively connected to the moving block 20 and the inner wall of the drive cavity 141. The elastic force of the elastic element 18 facilitates the movement of the movable block 20 towards the second tank 5 and its reset. The rotating assembly is located in the mixing chamber 142. The rotating assembly is used to drive the connecting shaft 8 to rotate. The connecting shaft 8 drives the cam 16 to rotate. The cam 16 drives the movable block 20 to move towards the second tank 5 and resets under the elastic force of the first elastic element 18. This process is repeated, continuously driving the movable block 20 to move horizontally back and forth. The movable block 20 drives the piston 15 to move in the second tank 5 through the push rod 17, causing the pressure in the second tank 5 to change.

[0037] like Figure 2 , Figure 5 As shown, a limiting groove 27 is horizontally opened on the upper part of the partition 14 near the moving block 20. A limiting block 28 is provided in the limiting groove 27. The limiting block 28 is slidably connected to the inner wall of the limiting groove 27 along the length of the limiting groove 27. The upper part of the limiting block 28 is connected to the lower part of the moving block 20, which makes the moving block 20 more stable when it moves along the upper part of the partition 14.

[0038] like Figure 2 , Figure 4 As shown, the rotating assembly includes a drive shaft 9, a motor 7, a first gear 12, and a second gear 13. The drive shaft 9 is vertically arranged in the mixing chamber 142 and positioned close to the connecting shaft 8. The lower end of the drive shaft 9 is rotatably connected to the partition plate 14, and the upper end of the drive shaft 9 passes through the top of the mixing chamber 142 and is located on the upper part of the housing 1. The motor 7 is located on the upper part of the housing 1, and the output end of the motor 7 is connected to the upper end of the drive shaft 9. The first gear 12 is sleeved on the drive shaft 9, and the second gear 13 is sleeved on the connecting shaft 8 and positioned close to the first gear 12. The second gear 13 is meshed with the first gear 12. When the motor 7 is started, the motor 7 drives the drive shaft 9 to rotate, the drive shaft 9 drives the first gear 12 to rotate, the first gear 12 drives the second gear 13 to rotate, the second gear 13 drives the connecting shaft 8 to rotate, and the connecting shaft 8 drives the cam 16 to rotate.

[0039] like Figure 2As shown, the lower end of the drive shaft 9 passes through the partition 14 and connects to the first stirring mechanism. The connecting shaft 8 is located close to the first tank 4. The upper end of the connecting shaft 8 passes through the top of the mixing chamber 142 and the lower part of the first tank 4 and connects to the second stirring mechanism. The connecting shaft 8 is rotatably and sealed to the lower part of the first tank 4. The connecting shaft 8 is connected to the cam 16 through a clutch assembly. There are multiple connecting shafts 8, which are evenly arranged around the drive shaft 9, meaning there are also multiple first tanks 4. Each first tank 4 is equipped with a second stirring mechanism, and each first tank 4 also has a corresponding second tank 5. Starting the motor 7 will simultaneously drive the drive shaft 9 and multiple connecting shafts 8 to rotate. The drive shaft 9 drives the first stirring mechanism to rotate, and the multiple connecting shafts 8 drive multiple second stirring mechanisms to rotate. Since various pesticides need to be added in sequence, the connection between the connecting shaft 8 and the cam 16 can be disconnected first through the clutch assembly on each connecting shaft 8. Then, the various pesticides and a small amount of water can be added to the multiple first tanks respectively. The mixing chamber 4 is stirred by the corresponding second stirring mechanism. After the initial mixing is completed, each connecting shaft 8 is connected to the cam 16 in sequence, and the mixture in each first tank 4 is added to the mixing chamber 142 in sequence. After completion, the connection between each connecting shaft 8 and the cam 16 is maintained, and air is injected into the mixing chamber 142 at a certain speed. This causes the mixture in the mixing chamber 142 to form local eddies at multiple different positions, further promoting the formation of turbulence, enhancing the diffusion ability of pesticides, breaking the interface between pesticides and water, and reducing the agglomeration force between wettable powder particles. This further reduces the agglomeration of wettable powders, making different pesticides disperse more evenly in water. At the same time, the motor 7 can provide power to the first stirring mechanism, the second stirring mechanism, and the horizontal reciprocating movement mechanism simultaneously through the transmission shaft 9 connected to the first stirring mechanism and the connecting shaft 8 connected to the second stirring mechanism. This not only enables the three to mix pesticides synchronously, but also saves energy.

[0040] like Figure 2 , Figure 5 , Figure 6As shown, the clutch assembly includes a first pawl disc 21, a second pawl disc 22, a control lever 39, and a connector. The first pawl disc 21 is sleeved on and rotatably connected to the connecting shaft 8. The cam 16 is sleeved on and fixedly connected to the first pawl disc 21, so that the rotation of the connecting shaft 8 will not cause the first pawl disc 21 and the cam 16 to rotate. The upper end of the first pawl disc 21 has a pawl structure. The second pawl disc 22 is sleeved on the connecting shaft 8 and located above the first pawl disc 21. The second pawl disc 22 is slidably connected to the connecting shaft 8. The lower end of the second pawl disc 22 has a pawl structure. There is a gap between the second pawl disc 22 and the first pawl disc 21, and the second pawl disc 22 can move towards the first pawl disc 21. After moving downwards, it engages with the first claw disc 21, meaning the first claw disc 21 and the second claw disc 22 can form a claw coupling. The connecting shaft 8 has a hollow internal structure, and the control rod 3 is vertically installed inside the connecting shaft 8. The upper end of the control rod 39 passes through the upper end of the connecting shaft 8 and the inlet 6 and is located outside the first tank body 4, making it easy to manually control via the control rod 39. The control rod 39 is rotatably and sealingly connected to the upper end of the connecting shaft 8 to prevent the mixed liquid from entering the connecting shaft 8. The connecting parts are connected to the control rod 39 and the second claw disc 22 respectively. The connecting parts are used to drive the second claw disc 22 to move up and down via the control rod 39, thereby controlling the engagement and disengagement of the second claw disc 22 with the first claw disc 21.

[0041] like Figure 6 , Figure 8 As shown, the connector includes a collar 30, which is sleeved on the control rod 39 and rotatably connected to it. The collar 30 is positioned close to the second pawl 22. Two guide grooves 29 are vertically and symmetrically formed on the side of the connecting shaft 8 near the collar 30. Each guide groove 29 communicates with the interior of the connecting shaft 8. A connecting rod 31 is horizontally arranged in each guide groove 29. The two ends of the connecting rod 31 are connected to the collar 30 and the second pawl 22, respectively, so that the second pawl 22 can be moved up and down by the up and down movement of the collar 30. A slider 34 is provided at the lower end of the control rod 39. A second elastic element 19 is vertically arranged in the connecting shaft 8 below the slider 34. The two ends of the second elastic element 19 are connected to the slider 34 and the bottom of the connecting shaft 8, respectively, so that the slider 34 can be reset after moving down. Two vertically symmetrical grooves 35 are formed on the inner wall of the connecting shaft 8 near the slider 34. Each groove 35 contains a guide block 45, which is slidably connected to the inner wall of the groove 35, allowing the guide block 45 to slide freely up and down the groove 35. One side of the guide block 45 is connected to the slider 34. Two arc-shaped grooves 36 are formed on the inner wall of the connecting shaft 8 near the lower end of each groove 35. The two arc-shaped grooves 36 are symmetrically arranged along the groove 35, and one end of each arc-shaped groove 36 is connected to the groove 35, so that the guide block 45 can move into one of the arc-shaped grooves 36 after moving to the lower end of the groove 35. Thus, the slider 34 is rotated by the rotation of the control rod 39, and the slider 34 drives the two guide blocks 45 to rotate in and out of the two arc-shaped grooves 36, fixing and releasing the slider 34.

[0042] like Figure 6 As shown, an annular groove 32 is provided on the inner side of the collar 30 along its circumference. A limiting ring 33 is fixedly sleeved on the control rod 39 near the annular groove 32. The outer side of the limiting ring 33 is located in the annular groove 32. The limiting ring 33 is slidably connected to the annular groove 32, which facilitates the rotation of the control rod 39 while driving the collar 30 to move up and down.

[0043] like Figure 1 , Figure 2 As shown, the first one-way conveying component includes a first connecting pipe 24 and a first one-way valve 26. The first connecting pipe 24 is disposed between the second tank 5 and the first tank 4. One end of the first connecting pipe 24 is connected to the first tank 4, and the other end of the first connecting pipe 24 is connected to the second tank 5, with the connection position located between the piston 15 and the housing 1. The first one-way valve 26 is disposed on the first connecting pipe 24. Through the first one-way valve 26, the mixture in the first tank 4 can enter the second tank 5 in one direction through the first connecting pipe 24.

[0044] like Figure 1 , Figure 2 As shown, the second one-way conveying component includes a second connecting pipe 25 and a second one-way valve 46. The second connecting pipe 25 is disposed between the second tank 5 and the nozzle 37. One end of the second connecting pipe 25 is connected to the second tank 5, and the other end of the second connecting pipe 25 passes through the side wall of the housing 1 and is connected to the nozzle 37. The second one-way valve 46 is disposed on the second connecting pipe 25. Through the second one-way valve 46, the mixture in the second tank 5 can enter the nozzle 37 in one direction through the second connecting pipe 25.

[0045] The second one-way valve 46 is a one-way pressure relief valve, which allows the mixture entering the second tank 5 to remain in the second tank 5 for a period of time, so that the pressure in the second tank 5 continues to increase. When the pressure exceeds the pressure setting value of the second one-way valve 46, the second one-way valve 46 opens to allow the mixture to enter the tank 1. Through the setting of the second one-way valve 46, the wettable powder particles in the mixture can be quickly dispersed in a small amount of water under continuous pressure, which accelerates the mixing of wettable powder particles and water. This makes the mixture more uniformly mixed with a large amount of water after entering the tank 1, further reducing the agglomeration of wettable powder and making different pesticides more uniformly dispersed in water.

[0046] like Figure 3 , Figure 4 As shown, a liquid inlet 44 is provided on the side of the box 1 near the upper part of the mixing chamber 142, so that water can be added into the box 1 through the liquid inlet 44.

[0047] like Figure 1 , Figure 2As shown, a movable frame 2 is provided at the lower part of the housing 1. Wheels are provided at the four corners of the lower part of the movable frame 2 to facilitate the movement of the housing 1 by the movable frame 2. A water pump 38 is provided at the upper part of the movable frame 2 near the housing 1. The input end of the water pump 38 is connected to the inside of the housing 1. A nozzle 3 is provided at the upper part of the movable frame 2. The nozzle 3 is connected to the output end of the water pump 38 through a pipe. When the water pump 38 is started, the water pump 38 delivers the mixed liquid inside the housing 1 to the nozzle 3 for spraying.

[0048] like Figure 2 As shown, the first stirring mechanism includes a plurality of first stirring blades 42, which are disposed in the mixing chamber 142 and are evenly arranged around the drive shaft 9. One end of each first stirring blade 42 is connected to the drive shaft 9, so that the plurality of first stirring blades 42 can be rotated by rotating the drive shaft 9.

[0049] like Figure 2 As shown, each second stirring mechanism includes multiple second stirring blades 43. The multiple second stirring blades 43 are arranged in the corresponding first tank 4 and are evenly arranged around the connecting shaft 8. One end of each second stirring blade 43 is connected to the connecting shaft 8, so that the multiple second stirring blades 43 can be rotated by the rotation of the connecting shaft 8.

[0050] Working principle: In use, the device is moved to a farmland. First, the height of each control lever 39 is detected, ensuring that the first claw disc 21 and second claw disc 22 on each connecting shaft 8 are initially separated. Then, the motor 7 is started, driving the transmission shaft 9 to rotate. The transmission shaft 9 drives the first gear 12 to rotate, which in turn drives multiple second gears 13. These second gears 13 then drive the corresponding connecting shafts 8 to rotate. The transmission shaft 9 drives multiple first stirring blades 42 to rotate, and each connecting shaft 8 drives multiple second stirring blades 43 to rotate. Then, a large amount of... Water is first added into the mixing chamber 142 through the inlet 44. Multiple first stirring blades 42 rotate, causing the water in the mixing chamber 142 to rotate. Then, various pesticides and a small amount of water are added into multiple first tanks 4 respectively. Multiple second stirring blades 43 in each first tank 4 rotate to stir and mix the pesticides and water. After the initial mixing is completed, the control lever 39 corresponding to the first pesticide to be added is pressed down in sequence. The control lever 39 drives the second claw plate 22 to move down through the collar 30 until the claw block at the lower end of the second claw plate 22 inserts into the first claw plate 2. The first claw disc 21 and the second claw disc 22 are engaged in the upper claw groove. Simultaneously, the slider 34 moves downwards along the connecting shaft 8, causing the two guide blocks 45 to move downwards along the two grooves 35 until they reach their lower ends. Then, the control lever 39 is gripped, making it stationary relative to the connecting shaft 8. The two guide blocks 45 rotate into the two arc-shaped grooves 36, fixing the position of the slider 34. This ensures that the first claw disc 21 and the second claw disc 22 are engaged. The connecting shaft 8 then drives the cam 16 to rotate via the first claw disc 21 and the second claw disc 22. The cam 16 drives the moving block 20 to move towards the second tank 5, and resets under the elastic force of the first elastic element 18. This process is repeated, continuously driving the moving block 20 to move horizontally back and forth. The moving block 20 drives the piston 15 to move inside the second tank 5 through the push rod 17, causing the pressure inside the second tank 5 to change. The mixture in the first tank 4 is pressurized and injected into the box 1, so that the mixture has a certain speed when it enters the rotating liquid, forming a local vortex. After the first pesticide is mixed, the above steps are repeated in sequence with other pesticides.
