Description

Technical Field

[0001] This invention relates to the technical field of pesticide production equipment, and in particular to a suspension pesticide production and processing equipment and its processing technology. Background Technology

[0002] Suspension pesticide production and processing equipment mainly disperses solid active ingredients evenly in an aqueous phase to prepare water-based environmentally friendly formulations with fine particle size, high suspension rate, and stable storage.

[0003] In the actual production process of pesticide suspensions, workers need to add various raw materials used to prepare pesticide suspensions, including solid technical materials, dispersants, wetting agents, thickeners, etc., to the mixing equipment in a certain proportion. Then, the mixing device is started, and the raw materials are thoroughly mixed by the high-speed rotation of the stirring paddle. During this process, the stirring paddle can promote the gradual dispersion of the components in the water, forming a preliminary suspension. However, in actual application, some solid technical materials may clump during storage or transportation. These clumps of pesticide particles are relatively large and difficult to break down and disperse sufficiently during traditional mixing processes. This results in poor uniformity of the final pesticide suspension, with differences in component content in different parts, which seriously affects the quality stability of the product. Summary of the Invention

[0004] This invention proposes a suspension pesticide production and processing equipment and process, which has the advantages of filtration and dispersion, and is used to solve the problem of uneven pesticide mixing caused by large raw material particles mentioned in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a suspension pesticide production and processing equipment, comprising: a processing tank, with a tank cover fixedly installed on the top, and a drive shaft driven by a motor installed at the bottom of the tank cover; a rotating core, movably installed inside the processing tank and driven by the drive shaft, the rotating core having filter holes on its side, and a cover plate movably fitted on the bottom inner side of the rotating core, a drive gear fixedly installed at the middle of the bottom inner side of the rotating core, and a driven gear meshing with the external teeth of the drive gear movably installed at the bottom of the cover plate, the rotating shaft of the driven gear being fixedly installed... Equipped with blades; a cylinder, fixed to the top of the tank cover, with an adjusting rod fixedly installed at the output end, and the bottom end of the adjusting rod fixedly connected to the cover plate; when the cylinder uses the adjusting rod to pull the rotating core upward, the blades driven by the motor uniformly stir the raw materials in each layer of the processing tank cavity. The upward rotating core will create a pressure difference between the upper and lower cavities of the processing tank, which will intensify the filtration of the raw materials through the filter holes, and large particles of raw materials filtered into the inner cavity of the rotating core will be broken and dispersed by the blades; when the rotating core moves downward, the pressure difference generated between the upper and lower cavities of the processing tank will cause the raw materials to flow in reverse through the filter holes, thereby clearing blockages.

[0006] Furthermore, the cross-sectional shape of the drive shaft is elliptical.

[0007] Furthermore, the inner cavity of the drive shaft is provided with a vent hole to allow the flow of the inner cavity of the treatment tank to go up and down, and a check valve is fixedly installed on the inner side of the drive shaft.

[0008] Furthermore, an adjusting plate is movably installed on the top inner side of the tank cover, and a detection ball is fixedly installed at the bottom of the adjusting plate above the inner cavity of the processing tank. The height of the detection ball is lower than the top opening of the vent hole, and a detection element is fixedly installed on the top of the tank cover. After the liquid level reaches the height of the detection ball, the detection ball is buoyed, causing the adjusting plate to rise and contact the detection element. The detection element sends a signal to the control system, and the control system adjusts the cylinder to stop pulling the rotating core upward, thereby preventing unfiltered raw materials from directly entering the vent hole.

[0009] Furthermore, an intake pipe is fixedly connected to the bottom of the outer side of the cylinder, and a damping pipe and a one-way intake valve are fixedly connected to the top of the cylinder, and both the intake pipe and the one-way intake valve are connected to the air source.

[0010] Furthermore, a positioning push seat is fixedly installed on the side of the adjusting rod, and an adjusting rod is movably installed on the side of the can lid. A metal disc is fixedly installed at one end of the adjusting rod, and an electromagnet assembly is fixedly installed on the side of the can lid. Multiple arc-shaped grooves are equidistantly opened on the side of the adjusting rod. By using the adjusting rod to abut against the grooves, the rotating core can be suspended at any height.

[0011] Furthermore, the outer side of the rotating core is provided with a spiral channel that makes active contact with the inner side of the processing tank. When the rotating core moves up or down, the rotating spiral channel scrapes the inner wall of the processing tank and conveys the agglomerated material upward.

[0012] Furthermore, there are two detection elements, which are arranged vertically on one side of the adjustment plate.

[0013] Furthermore, an adjusting sleeve is fixedly installed in the middle of the adjusting rod, and a pressure roller located above the outer side of the adjusting sleeve is fixedly installed on the side of the adjusting plate.

[0014] A processing technology for a suspension pesticide production and processing equipment includes the following steps:

[0015] S1. Pour the raw materials and water solvent for processing suspension pesticides into the processing tank. The raw materials fall into the inner cavity of the rotating core and are filtered through the filter holes. The raw materials that meet the particle size requirements pass through the filter holes with the water solvent, while the large particles remain in the inner cavity of the rotating core.

[0016] S2. Start the motor and drive the rotating core to rotate through the transmission shaft. Because the cover plate cannot rotate due to the restriction of the adjusting rod, the rotating core and the cover plate rotate relative to each other. The rotating core drives the drive gear to rotate. By using the meshing transmission between the drive gear and the driven gear, the driven gear drives the blade to rotate, crushing and dispersing the large particles of raw material in the rotating core.

[0017] S3. The cylinder drives the cover plate to move up and down reciprocally through the adjusting rod. The blades rotate and move up and down to stir the raw materials and water solvent, and stir and mix the raw materials in each layer of the treatment tank.

[0018] S4. When the rotating core moves upward, the pressure in the lower area is relatively lower than that in the upper area. Large particles are filtered into the inner cavity of the rotating core, and the blades crush and disperse the large particles. When the rotating core moves downward, the pressure in the lower area tends to be relatively greater than that in the upper area. The water solvent in the inner cavity of the treatment tank backflows through the filter holes to clear blockages and mixes with the raw materials again.

[0019] The beneficial effects of this invention are as follows:

[0020] This invention provides a suspension pesticide production and processing equipment and its processing technology. A motor and cylinder are installed on the processing tank to drive a rotating core in reciprocating motion and rotation. During the upward movement of the core, several filter holes are provided on the side of the core. When the raw material flows through the filter holes, large particles cannot pass through due to their size and are effectively intercepted and concentrated inside the core. Simultaneously, multiple blades are installed inside the core. As the core rotates, the blades break up the large particles concentrated inside the core, thereby achieving preliminary filtration and dispersion of the suspension pesticide raw material.

[0021] Furthermore, as the rotating core descends, the crushed raw materials come into full contact with and mix with the water-soluble solvent again. Simultaneously, the rotating blades follow the core downwards, continuously rotating to agitate and mix the raw materials and water-soluble solvent. Moreover, as the core drives the blades downwards, the blades sequentially mix the raw materials in each layer of the processing tank, ensuring thorough mixing in each area and ultimately achieving a uniform mixture of raw materials and water-soluble solvent.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1, please refer to Figure 1 and Figure 2 As can be seen, the side of the treatment tank 1 is symmetrically fitted with mounting lugs for securing the equipment. Furthermore, the side of the treatment tank 1 has a transparent glass viewing window, allowing for a direct view of the tank's internal workings. A discharge pipe is fixedly connected to the bottom of the treatment tank 1, allowing the prepared pesticide suspension to be discharged. During normal operation, the discharge pipe is sealed with a valve to ensure a relatively airtight seal within the treatment tank 1.

[0034] The top of the processing tank 1 has a tank cover 2 that is fastened to the top by a flange, combined with Figure 2 and Figure 5It can be seen that a feed pipe is fixedly connected to the top of the tank lid 2, and the raw materials required for preparing suspension pesticides can be poured sequentially into the inner cavity of the processing tank 1 through this pipe. In the process of processing and producing suspension pesticides, to avoid uneven distribution of pesticide raw materials due to large particle sizes, this application proposes a suspension pesticide production and processing equipment. Figures 2-5 It can be seen that a motor 3 is fixedly installed on the top of the can lid 2, and a transmission shaft 11 is coaxially and fastened to the output shaft of the motor 3. The central axis of the transmission shaft 11 coincides with the central axis of the inner cavity of the processing can 1. Preferably, the cross-sectional shape of the transmission shaft 11 is elliptical. When the motor 3 is powered by mains electricity, it can drive the transmission shaft 11 to rotate in the inner cavity of the processing can 1.

[0035] The inner cavity of the processing tank 1 is fitted with a rotating core 9, such as Figure 3 As shown, the rotating core 9 is a cylindrical tube with a stepped side and an upward-opening interior. A sealed movable assembly is fitted between the center of the rotating core 9 and the drive shaft 11. In this way, the drive shaft 11 can not only drive the rotating core 9 to rotate, but the rotating core 9 can also reciprocate up and down along the central axis of the drive shaft 11. Furthermore, combined with… Figures 2-4 It can be seen that the side of the rotating core 9 has multiple filter holes 901 arranged at equal angles for filtering large particles of raw materials. From Figure 3 and Figure 4 It can be seen that a cover plate is movably fitted inside the bottom of the rotating core 9, and the cover plate and the rotating core 9 are sealed together. Specifically, the upper and lower ends of the cover plate are restricted by retaining rings, ensuring that the cover plate can only rotate inside the rotating core 9. A sealing area for installing gears is provided between the bottom of the cover plate and the inner side of the rotating core 9. Specifically, a drive gear 13 is fixedly installed in the middle of the bottom of the inner side of the rotating core 9, located in this sealing area. Correspondingly, a driven gear 14 that meshes with the external teeth of the drive gear 13 is movably installed at the bottom of the cover plate, and a blade 15 located above the cover plate is fixedly installed on the shaft of the driven gear 14. When the drive shaft 11 drives the rotating core 9 and the drive gear 13 to rotate, if the cover plate remains fixed, the meshing transmission of the drive gear 13 and the driven gear 14 forces the driven gear 14 to drive the blade 15 to rotate, thereby using the blade 15 to crush the large particles of raw material filtered in the inner cavity of the rotating core 9. Figure 4 It is evident that the diameter of the drive gear 13 is larger than that of the driven gear 14. Therefore, when the drive gear 13 drives the driven gear 14 to rotate, it forms an acceleration gear set, ensuring that the blades 15 rotate at high speed and shear and crush the raw materials. In practical applications, the number of driven gears 14 and blades 15 can be multiple, ensuring that the multiple driven gears 14 are arranged in a ring at equal angles along the central axis of the cover plate. The number of blades 15 used can be adjusted according to actual usage requirements.

[0036] To ensure the cover plate remains relatively fixed in position, combined with Figure 2 , Figure 3 and Figure 5 It can be seen that a cylinder 4 is fixedly installed at the top of the can lid 2, and an adjusting rod 12 is fixedly installed at the output end of the cylinder 4. The bottom end of the adjusting rod 12 is fixedly connected to the cover plate. In this way, when the air source is input into the cylinder 4, the cylinder 4 drives the cover plate to move up and down through the adjusting rod 12, that is, the rotating core 9 moves up and down.

[0037] In practical applications, the specific working principle of this embodiment is as follows:

[0038] The raw materials for processing suspension pesticides and the aqueous solvent are poured in sequentially through the feed pipe. The raw materials entering the inner cavity of the processing tank 1 fall into the inner cavity of the rotating core 9 and are filtered through the filter holes 901. This allows the raw materials that meet the particle size requirements to pass through the filter holes 901 with the aqueous solvent, while the larger particles remain in the inner cavity of the rotating core 9.

[0039] Secondly, the motor 3 starts and drives the transmission shaft 11 to rotate synchronously, which in turn drives the rotating core 9 to rotate synchronously. During this process, the cover plate cannot rotate due to the restriction of the adjusting rod 12, resulting in relative rotation between the cover plate and the rotating core 9. When the rotating core 9 drives the drive gear 13 to rotate, the meshing transmission between the drive gear 13 and the driven gear 14 forces the driven gear 14 to drive the blades 15 to rotate at high speed. The high-speed rotating blades 15 are used to break and disperse the water solvent containing large particles in the inner cavity of the rotating core 9, thereby breaking the large particles of raw material into small particles.

[0040] Furthermore, in this embodiment, cylinder 4 is controlled by an air source, and the adjusting rod 12 causes the cover plate to drive the rotating core 9 to reciprocate up and down. During this reciprocating motion, the rotating core 9 drives the blades 15 to move up and down. Due to the rotation of the blades 15, the raw materials and water-soluble solvents are effectively stirred and mixed. Combined with the adjusting rod 12 driving the rotating core 9 to reciprocate up and down along the inner cavity of the processing tank 1, the blades 15 can stir and mix the raw materials in each layer of the inner cavity of the processing tank 1. Simultaneously, as the adjusting rod 12 drives the rotating core 9 upwards, the pressure in the lower area of ​​the rotating core 9 is relatively lower than that in the upper area. As the rotating core 9 moves upward, the raw materials and water solvent are filtered, causing large particles to be filtered into the inner cavity of the rotating core 9. The blades 15 can more effectively break and disperse the large particles. Similarly, when the cylinder 4 pushes the rotating core 9 downward through the adjusting rod 12, the pressure in the area below the rotating core 9 tends to be relatively greater than that in the area above. Therefore, the water solvent in the inner cavity of the processing tank 1 will reverse through the filter hole 901, which not only achieves backflushing and clearing of the filter hole 901, but also mixes the water solvent with the raw materials again through the water solvent entering the inner cavity of the rotating core 9.

[0041] As cylinder 4 drives rotor 9 to move up and down continuously, and motor 3 drives blades 15 to rotate at high speed, the large particles in the inner cavity of processing tank 1 are filtered, crushed, and then remixed. This cycle continues until the production and processing of the suspension pesticide is complete. Finally, the prepared suspension pesticide is discharged through the discharge pipe at the bottom of processing tank 1.

[0042] Example 2 is a further improvement on Example 1. Please refer to Example 1. Figures 2-4 It can be seen that the inner cavity of the drive shaft 11 has a vent hole 110 to allow vertical flow within the inner cavity of the processing tank 1. A check valve 111 is fixedly installed on the inner side of the drive shaft 11 and at the top of the vent hole 110. The check valve 111 restricts the airflow above the processing tank 1 from flowing downwards along the vent hole 110. In this way, when the adjusting rod 12 pulls the rotating core 9 upwards, if the filter hole 901 is blocked during the upward movement of the rotating core 9, the upward movement of the rotating core 9 will cause the pressure above the inner cavity of the processing tank 1 to increase. When the pressure exceeds the starting resistance of the check valve 111, the check valve 111 is opened. At this time, the air above the inner cavity of the processing tank 1 will enter the lower part of the inner cavity of the processing tank 1 through the vent hole 110, thereby avoiding the problem of excessive pressure in the upper inner cavity of the processing tank 1 causing difficulty in the upward movement of the rotating core 9.

[0043] Example 3, as a supplement to Example 2, combines... Figure 3 , Figure 5 and Figure 6 As can be seen, an adjusting plate 5 is movably installed on the top inner side of the can lid 2, and a detection ball 502 is fixedly installed at the bottom of the adjusting plate 5 above the inner cavity of the processing tank 1. The detection ball 502 is preferably a hollow sphere, and its height is lower than the top opening of the vent hole 110. At the same time, a detection element 6 is fixedly installed on the top of the can lid 2. Under normal conditions, the detection ball 502, under the action of gravity, keeps the top of the adjusting plate 5 relatively away from the detection element 6. When the adjusting rod 12 pulls the rotating core 9 upward, if the filter hole 901 is blocked above the rotating core 9, resulting in excessive raw material and water solvent, the liquid level of the raw material will rise as the rotating core 9 moves upward. When the liquid level passes the detection ball 502, the buoyancy will push the detection ball 502 upward until the adjusting plate 5 moves upward and passes the detection element 6. After that, the detection element 6 will send an electrical signal to the control system, which will use the control system to stop the cylinder 4 from pulling the rotating core 9 upward. In this way, the rotating core 9 is prevented from pushing the liquid level above it too high, which would cause unfiltered and uncrushed raw material to flow directly into the bottom of the inner cavity of the processing tank 1 through the vent hole 110.

[0044] Example 4 is a further improvement on Example 3. During the preparation process, pesticide residues may appear inside the treatment tank 1, which can easily lead to clumping or scaling over time. Although the rotating core 9 can clean the inside of the treatment tank 1 by moving up and down along its inner wall, if scaling or clumping forms on the inner wall, directly scraping it with the rotating core 9 can cause the clumping to be scraped to the lower part of the inner cavity of the treatment tank 1. Subsequently, because the clumping cannot pass through the filter holes 901, the raw material clumping or scaling cannot be broken up. Example 4 addresses this problem by combining... Figure 1 As can be seen, unlike Embodiment 1, the cylinder 4 in this application provides a damping lifting effect on the rotating core 9. More specifically, an air inlet pipe 401 is fixedly connected to the bottom of the outer side of the cylinder 4. The air inlet pipe 401 is generally connected to an air source. A damping pipe 402 and a one-way air inlet valve 403 are fixedly connected to the top of the cylinder 4. When the piston inside the cylinder 4 moves upward, the air above the piston can only flow out slowly from the damping pipe 402, thereby slowing down the upward speed of the cylinder 4 driving the adjusting rod 12. When the cylinder 4 moves downward, the air source is connected through the one-way air inlet valve 403, thereby quickly pushing the cylinder 4 downward.

[0045] Moreover, combined Figures 2-4 It can be seen that a positioning push seat 121 is fixedly installed on the side of the adjusting rod 12. The positioning push seat 121 is in the shape of an inverted frustum. Correspondingly, an adjusting rod 7 is movably installed on the side of the can lid 2. The end of the adjusting rod 7 is spherical. Figure 2 , Figure 3 and Figure 5 It can be seen that a metal plate is fixedly installed at one end of the adjusting rod 7 on the outer side of the can lid 2, and an electromagnet assembly 8 is fixedly installed on the side of the can lid 2. When the electromagnet assembly 8 is energized and generates magnetism, it will attract the adjusting rod 7, causing one end of the adjusting rod 7 to press against the side of the adjusting rod 12. By changing the magnitude of the electromagnetic force of the electromagnet assembly 8, the strength of the adjusting rod 7 pushing against the adjusting rod 12 can be changed. Furthermore, combined with... Figures 2-4As can be seen, multiple arc-shaped grooves are equidistantly arranged on the side of the adjusting rod 12. When the cylinder 4 pushes the rotating core 9 downward, if an external operator needs to focus on crushing and dispersing the raw materials at a specific height using the viewing window, the control system activates the electromagnet assembly 8 after the rotating core 9 has reached the desired position. The generated magnetism attracts the metal disc at the end of the adjusting rod 7, forcing the adjusting rod 7 further into the arc-shaped groove on the side of the adjusting rod 12. Simultaneously, the air supply to the one-way air inlet valve 403 is stopped. Thus, the position of the adjusting rod 12 can be restricted using the adjusting rod 7, which in turn restricts the position of the rotating core 9 through the cover plate, causing the rotating core 9 to hover at a fixed height. For subsequent resetting, the cylinder 4 can pull the rotating core 9 upward for resetting; the specific steps can be found in the subsequent working principle of the rotating core 9's upward movement. This method ensures that the rotating core 9 can be suspended at any height for crushing and dispersion, thereby allowing for focused crushing and dispersion of raw materials at different heights.

[0046] Combination Figure 2 and Figure 3 As can be seen, the outer side of the rotating core 9 is provided with a spiral channel 902 that is in active contact with the inner side of the treatment tank 1. When the rotating core 9 drives the spiral channel 902 to rotate along the inner wall of the treatment tank 1, the spiral channel 902 can scrape off the clumps or scale on the side of the treatment tank 1 and transport them to the top of the rotating core 9.

[0047] Combination Figure 3 , Figure 5 and Figure 6 It can be seen that there are two detection elements 6, which are arranged vertically and located on one side of the adjusting plate 5. An adjusting sleeve 10 is fixedly installed in the middle of the adjusting rod 7. The adjusting sleeve 10 is a cylindrical tube with steps. Correspondingly, a pressure roller 501 is fixedly installed on the side of the adjusting plate 5, located above the outer side of the adjusting sleeve 10. By pressing the adjusting sleeve 10 at different positions on the side by the pressure roller 501, the two detection elements 6 can send different response signals to the control system.

[0048] Specifically, in practical applications, the working principle of this embodiment is as follows:

[0049] Rotating core 9 downward state: At this time, the electromagnet assembly 8 stops working, and the detection ball 502 is driven by gravity to make the adjusting plate 5 drive the pressure roller 501 downward. The pressure roller 501 presses on the larger diameter side of the left side of the adjusting sleeve 10. At this time, the end of the adjusting plate 5 only blocks the detection element 6 below. The air source stops supplying airflow to the air inlet pipe 401 and supplies airflow to the one-way air inlet valve 403.

[0050] Secondly, the control system causes the motor 3 to drive the transmission shaft 11 to rotate. When the motor 3 drives the rotating core 9 to rotate through the transmission shaft 11, on the one hand, the rotating core 9 drives the drive gear 13 to mesh with the driven gear 14, so that the blades 15 crush and stir the raw materials in the inner cavity of the processing tank 1. On the other hand, when the rotating core 9 rotates, the spiral channel 902 on the outside of the rotating core 9 contacts the inner wall of the processing tank 1, forcing the spiral channel 902 to scrape the inner side of the processing tank 1. Under the conveying of the spiral channel 902, the scraped lumps are conveyed to the top of the rotating core 9 until they fall into the inner cavity of the rotating core 9 for crushing.

[0051] Furthermore, when cylinder 4 rapidly pushes the rotating core 9 downward via adjusting rod 12, the water-soluble solvent inside the treatment tank 1 and located below the rotating core 9 is conveyed upward along the spiral channel 902, intensifying the upward conveying of the agglomerates scraped off by the spiral channel 902. Simultaneously, the water-soluble solvent is reverse-impacted through the filter holes 901, thus clearing the blockage. Figure 7 As shown in the diagram, when cylinder 4 pushes the rotating core 9 down to the bottom, the positioning push seat 121 immediately moves to the end of the adjusting rod 7. Using the trapezoidal inclined surface of the positioning push seat 121, the adjusting rod 7 moves to the left. After the adjusting rod 7 moves to the left, it drives the adjusting sleeve 10 to move to the left. The outer side of the small diameter on the right side of the adjusting sleeve 10 moves below the pressure roller 501. Then, under the action of gravity, the detection ball 502 causes the adjusting plate 5 to move down, and the pressure roller 501 moves down and presses down on the outer side of the small diameter of the adjusting sleeve 10. As the detection ball 502 drives the adjusting plate 5 down, the adjusting plate 5 also moves away from the detection element 6 below. The detection element 6 below then knows that the rotating core 9 has reached the top and changes the air source input through the control system to make the rotating core 9 move upward.

[0052] The upward state of the rotating core 9; that is Figure 8 As shown, at this time, the air source is input into the inner cavity of the cylinder 4 through the air inlet pipe 401, and the one-way air inlet valve 403 stops the air supply. Afterwards, as the air source is supplied through the air inlet pipe 401, the airflow in the inner cavity of the cylinder 4 is slowly discharged from the damping pipe 402, thereby slowing down the upward speed of the rotating core 9. During this process, the upward movement of the rotating core 9 will cause the pressure in the chamber below it to decrease relatively, allowing the raw materials in the inner cavity of the rotating core 9 to be filtered through the filter hole 901. The rotating core 9 itself is driven by the drive shaft 11 to rotate, and then uses the spiral channel 902 to transport the aqueous solution and any clumps that may appear inside the treatment tank 1 to the upper part of the rotating core 9 again. When the clumps generated inside the treatment tank 1 are scraped by the rotating core 9, the clumps can only be transported towards the inner cavity of the rotating core 9.

[0053] When cylinder 4 moves the rotating core 9 upward via adjusting rod 12, if filter hole 901 becomes clogged, the liquid surface above the rotating core 9 will first contact the detection ball 502. Under buoyancy, the detection ball 502 pushes the adjusting plate 5 and the pressure roller 501 on the side of the adjusting plate 5 upward. The upward-moving adjusting plate 5 eventually connects the detection elements 6 below and above in sequence. At this time, the upward height of the pressure roller 501 has exceeded the adjusting sleeve 10. Afterward, the control system will connect the electromagnet assembly 8, which will generate force on the adjusting rod 7. Magnetic attraction causes the end of adjusting rod 7 to abut the side of adjusting rod 12. The control system then changes the air input, causing cylinder 4 to push rotating core 9 downwards via adjusting rod 12. As core 9 descends, the liquid level decreases, and detection ball 502, under gravity, moves adjusting plate 5 downwards. Adjusting plate 5 moves away from the upper detection element 6, which sends a signal to the control system. The control system then stops the electromagnet assembly 8. Finally, pressure roller 501 presses against the outer side of the large diameter on the left side of adjusting sleeve 10. This process is then repeated cyclically.

[0054] If the filter hole 901 is not blocked during the upward movement of the rotating core 9, the top of the upward rotating core 9 will eventually reach the detection ball 502, and then the air source reversal input mentioned above will be realized.

[0055] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.

10. A processing technology for a suspension pesticide production and processing equipment, using the suspension pesticide production and processing equipment as described in claim 1, characterized in that, Includes the following steps: S1. Pour the raw materials and water solvent for processing suspension pesticides into the processing tank (1). The raw materials fall into the inner cavity of the rotating core (9) and are filtered through the filter hole (901). The raw materials that meet the particle size requirements pass through the filter hole with the water solvent, while the large particles remain in the inner cavity of the rotating core (9). S2. Start the motor (3), drive the rotating core (9) to rotate through the transmission shaft (11). Because the cover plate is restricted by the adjusting rod (12) and cannot rotate, the rotating core (9) and the cover plate rotate relative to each other. The rotating core (9) drives the drive gear (13) to rotate. By using the meshing transmission between the drive gear (13) and the driven gear (14), the driven gear (14) drives the blade (15) to rotate, crushing and dispersing the large particles of raw material in the rotating core (9). S3, the cylinder (4) causes the cover plate to drive the rotating core (9) to move up and down repeatedly through the adjusting rod (12), and the blade (15) rotates and moves up and down to stir the raw materials and water solvent, and stirs and mixes the raw materials in each layer of the treatment tank (1); S4. When the rotating core (9) moves upward, the pressure in the lower region is relatively lower than that in the upper region. Large particles are filtered into the inner cavity of the rotating core (9), and the blades (15) break and disperse the large particles. When the rotating core (9) moves downward, the pressure in the lower region tends to be relatively greater than that in the upper region. The water solvent in the inner cavity of the treatment tank (1) is backflushed and cleared through the filter hole (901) and mixed with the raw material again.
