Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, and in particular to a precise quantitative spraying device for soil remediation. Background Technology

[0002] In integrated soil remediation operations, soil quality needs to be improved by spraying chemicals. It is necessary to ensure that the chemicals are mixed evenly with water to avoid local concentration imbalances that may affect the remediation effect, and to prevent impurities in the chemicals from clogging equipment components and causing spraying interruptions.

[0003] Existing pesticide spraying devices rely solely on simple stirring rods or manual mixing, which easily leads to pesticide clumping and uneven mixing. This results in excessively high local pesticide concentrations in the soil after spraying, causing ecological damage, or insufficient concentrations, failing to achieve the desired treatment effect. Furthermore, pesticides tend to accumulate at the bottom of the tank, leading to waste. At the same time, undissolved particles in the pesticide and dust mixed in during storage can easily enter the water pump and spray head along with the pesticide, causing component blockages. This not only requires frequent shutdowns for cleaning, affecting operational efficiency, but may also damage the equipment due to blockages, increasing maintenance costs.

[0004] Therefore, those skilled in the art have provided a precise quantitative spraying device for integrated soil management to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a precise quantitative spraying device for soil remediation. Through a specially designed stirring mechanism, the main stirring rod and auxiliary stirring rod rotate in tandem, working in conjunction with a T-shaped dispersing rod to achieve comprehensive and uniform mixing of the pesticide, preventing clumping and maintaining consistent concentration. To improve soil remediation effectiveness, the bottom material distribution plate also prevents pesticide deposition, waste, and deterioration. At the same time, the filter mechanism intercepts impurities to prevent clogging of the spray head and flow controller, ensuring smooth operation of the device. The annular sealing ring prevents pesticide leakage, avoiding waste and safety hazards. The snap-fit ​​structure facilitates quick replacement of the filter screen. The combination of these two features makes the pesticide spraying more uniform and the device operation more stable, improving soil remediation efficiency and safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A precise quantitative spraying device for soil remediation includes a base plate. Mounting frames and a pesticide storage tank are fixedly connected to both sides of the upper surface of the base plate. A flow controller is fixedly mounted on the mounting frame. A water storage head is fixedly connected to one side of the flow controller. Multiple spray heads are fixedly connected to one side of the water storage head. A water pump is fixedly connected to the outer wall of one side of the pesticide storage tank. A water guide pipe is fixedly connected between the water pump and the flow controller. A corrugated pipe is fixedly connected to the lower end of the water pump. An L-shaped connecting pipe is fixedly connected to one side of the pesticide storage tank. A stirring mechanism is installed inside the pesticide storage tank. A filtration mechanism is installed between the corrugated pipe and the L-shaped connecting pipe. The stirring mechanism includes a protective frame, a driving gear, and two driven gears. A main stirring rod is rotatably connected to the center of the upper inner wall of the medicine storage box. Auxiliary stirring rods are rotatably connected to both sides of the upper inner wall of the medicine storage box. Multiple T-shaped dispersing rods are fixedly connected to the outer walls of both sides of the main stirring rod and the outer walls of one side of the two auxiliary stirring rods. A connecting rod is fixedly connected to the lower end of the main stirring rod, and a bottom material equalization plate is fixedly connected to one side of the lower end face of the connecting rod. Through the above technical solution, the set stirring mechanism can achieve all-round uniform mixing of the agent in the agent storage tank. Specifically, the drive motor drives the main stirring rod to rotate, and the main stirring rod drives the auxiliary stirring rods on both sides to rotate synchronously through the meshing of the active gear. Multiple T-shaped dispersing rods on the main and auxiliary stirring rods rotate with the rods, dispersing the agent and water at multiple angles to prevent the agent from clumping. The connecting rod at the lower end of the main stirring rod drives the bottom uniform plate to scrape the bottom of the tank to prevent the agent from settling at the bottom of the tank, ensuring that the agent concentration in the tank is consistent, laying the foundation for subsequent precise quantitative spraying. At the same time, the protective frame can isolate the gear set from the agent, preventing the agent from corroding the gears and affecting the transmission.

[0007] Furthermore, the filtering mechanism includes a filter ring, and a connecting sleeve is fixedly connected to the lower end of the corrugated pipe and the upper end of the L-shaped connecting pipe. A fixing opening is provided on the upper end face of the filter ring, and a filter screen is fixedly sleeved in the fixing opening. Through the above technical solution, the set filtration mechanism can intercept impurities before the agent is delivered. That is, the agent flows from the L-shaped connecting pipe into the lower connecting sleeve, and then passes through the filter screen in the filter ring fixing port. The filter screen can effectively intercept undissolved particles, dust and other impurities in the agent. The purified agent enters the corrugated pipe through the upper connecting sleeve. The filter ring connects the corrugated pipe and the L-shaped connecting pipe, which not only ensures a smooth agent delivery path, but also prevents impurities from entering the water pump, flow controller or spray head with the agent through filtration, preventing component blockage and ensuring continuous spraying operation.

[0008] Furthermore, annular sealing rings are fixedly connected to both the upper and lower end faces of the filter ring, and annular sealing grooves are opened on the opposite sides of the two connecting sleeves, with the two annular sealing rings respectively engaging and fitting into the corresponding annular sealing grooves. The above technical solution involves inserting the annular sealing rings at the upper and lower ends of the filter ring into the annular sealing grooves of the corresponding connecting sleeve, filling the gap between the two. This prevents the pesticide from leaking through the gaps during transportation, reducing pesticide waste and preventing leaked pesticide from contaminating the soil or coming into contact with operators, thus improving operational safety. At the same time, the sealing structure can maintain stable pesticide delivery pressure, ensuring that the flow controller can accurately regulate the pesticide flow and guarantee the quantitative spraying effect.

[0009] Furthermore, limiting posts are fixedly connected to both sides of the upper and lower end faces of the filter ring. An adjustment groove is provided on one side of the limiting post near the front and rear. A return spring is fixedly connected to the inner wall of one side of the adjustment groove. A movable seat is fixedly connected to one side of the return spring. A locking rod is fixedly connected to one side of the movable seat. A limiting port is provided on the opposite side of the two connecting sleeves near the front and rear. The limiting post is locked in the limiting port. Locking holes are provided on both sides of the two connecting sleeves near the front and rear. The locking holes are connected to the limiting ports. The locking rod is locked in the locking holes. With the above technical solution, by pressing the locking rod to compress the return spring in the adjusting groove, after the limiting post is fully engaged, the return spring pushes the locking rod into the locking hole of the connecting sleeve to fix the position of the filter ring. When disassembling, pressing the locking rod can unlock it without tools, which is convenient for regular cleaning or replacement of the filter screen. In addition, the cooperation between the limiting post and the limiting port can also prevent the filter ring from rotating, ensuring that the filter screen is always in the correct filtration position and improving filtration reliability.

[0010] Furthermore, the upper and lower end faces of the movable seat are fixedly connected to limit sliders, and the inner walls of the upper and lower ends of the adjustment groove are provided with limit grooves, and the limit sliders are slidably disposed in the limit grooves. Through the above technical solution, when the moving seat drives the locking rod to move along the adjustment groove, the upper and lower limit sliders slide along the limit slide groove in the adjustment groove, which constrains the movement trajectory of the moving seat, prevents the moving seat from deviating or tilting, and ensures that the locking rod is always aligned with the locking hole of the connecting sleeve. This avoids the filter ring from failing to be fixed due to misalignment, thereby preventing the filter ring from loosening and shifting during operation and ensuring the stability of drug filtration and delivery.

[0011] Furthermore, the driving gear is fixedly sleeved on the upper part of the outer wall of the main stirring rod, and the two driven gears are respectively fixedly sleeved on the upper part of the outer wall of the corresponding auxiliary stirring rod. The protective frame is fixedly connected to the upper inner wall of the medicine storage box, and the driving gear and the two driven gears are movably arranged inside the protective frame. Through the above technical solution, the active gear rotates with the main stirring rod, meshing with and driving the two driven gears to rotate synchronously, realizing the coordinated rotation of the main and auxiliary stirring rods, ensuring that the stirring range covers the entire reagent storage tank; the protective frame encloses the active and driven gears, preventing reagents from splashing and contacting the gears during stirring, preventing reagents from corroding the gears or impurities from gear wear from mixing into the reagents, extending the service life of the gear set, and ensuring the long-term stable operation of the stirring mechanism.

[0012] Furthermore, a drive motor is fixedly connected to the upper end face of the medicine storage box, and the output end of the drive motor is fixedly connected to the main stirring rod; The above technical solution allows for precise control of the main stirring rod's speed by directly connecting the drive motor output end to the main stirring rod. This adapts to the mixing requirements of different agents. Compared to manual stirring, motor-driven stirring is more labor-saving and provides uniform stirring speed, avoiding uneven mixing of agents caused by uneven stirring force in manual stirring. At the same time, the motor operates stably and can operate continuously for a long time, meeting the spraying needs of large-scale integrated soil management.

[0013] Furthermore, casters are fixedly connected to the lower end face of the base plate near the four corners, and a control panel is fixedly connected to the front end face of the medicine storage box; The above technical solution allows operators to easily move the device in the field using the casters at the bottom of the base plate, adapting to soil remediation operations in different areas. It eliminates the need for large equipment for transport, reducing the intensity of work. The control panel at the front of the pesticide storage tank can intuitively display and adjust the pump start / stop, flow controller parameters, drive motor speed, etc. Operators can complete various operations without frequently touching the internal parts of the equipment, simplifying the work process and improving spraying efficiency.

[0014] This utility model has the following beneficial effects: 1. This utility model proposes a precise quantitative spraying device for integrated soil remediation. Through the addition of a stirring mechanism, the main stirring rod and auxiliary stirring rod rotate in tandem, and together with the T-shaped dispersing rod, the agent is stirred in all directions. This effectively avoids agent clumping or uneven mixing, ensuring consistent agent concentration, improving soil remediation effect, and preventing localized excessively high agent concentrations that damage the soil ecology or excessively low concentrations that lead to treatment failure. In addition, the bottom material distribution plate scrapes the agent at the bottom of the tank, preventing agent deposition and waste, reducing the risk of agent deterioration at the bottom of the tank, extending the agent's service life, and protecting the gear set from agent corrosion or impurities from gear wear into the agent. This ensures long-term stable operation of the stirring mechanism, reduces equipment maintenance frequency and cost, and is suitable for long-term soil remediation operations.

Through the addition of a filtration mechanism, the filter screen effectively intercepts impurities in the pesticide, preventing clogging of the spray head or flow controller, ensuring smooth operation of the spraying device, reducing equipment downtime due to component blockage, and improving the efficiency of soil remediation operations. Furthermore, the cooperation between the annular sealing ring and the sealing groove achieves a sealed connection, preventing pesticide leakage and waste, while also preventing soil contamination or operator contact with the pesticide, thus improving operational safety. Simultaneously, the cooperation between the locking rod and the locking hole facilitates quick disassembly of the filter ring, allowing for regular cleaning or replacement of the filter screen. Operation requires no tools, reducing maintenance difficulty. The limit slider ensures stable locking, preventing the filter ring from loosening or shifting during operation, ensuring continuous and reliable filtration.

[0016] 3. This utility model proposes a precise quantitative spraying device for comprehensive soil remediation. Through a set stirring mechanism, the main stirring rod and the auxiliary stirring rod rotate in tandem, and together with the T-shaped dispersing rod, the agent is uniformly stirred in all directions, preventing clumping and maintaining consistent concentration, thus improving the soil remediation effect. The bottom uniform plate can also prevent agent deposition, waste, and deterioration. At the same time, through the set filtration mechanism, the filter screen can intercept impurities to prevent clogging of the spray head and flow controller, ensuring smooth operation of the device. The annular sealing ring prevents agent leakage, avoiding waste and safety hazards. The snap-fit ​​structure facilitates quick replacement of the filter screen. The combination of these two features makes the agent spraying more uniform, the device operation more stable, and improves the efficiency and safety of soil remediation. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Referring to Figures 1, 2, and 4, this utility model provides a specific embodiment: a precise quantitative spraying device for soil remediation, comprising a base plate 1, with mounting frames 8 and a pesticide storage box 3 fixedly connected to both sides of the upper end face of the base plate 1, a flow controller 9 fixedly mounted on the mounting frame 8, a water storage head 10 fixedly connected to one side of the flow controller 9, and multiple spray heads 11 fixedly connected to one side of the water storage head 10, a water pump 6 fixedly connected to one side of the outer wall of the pesticide storage box 3, a water guide pipe 12 fixedly connected between the water pump 6 and the flow controller 9, a corrugated pipe 7 fixedly connected to the lower end of the water pump 6, an L-shaped connecting pipe 5 fixedly connected to one side of the pesticide storage box 3, a stirring mechanism 13 provided inside the pesticide storage box 3, and a filtering mechanism 14 provided between the corrugated pipe 7 and the L-shaped connecting pipe 5; The stirring mechanism 13 includes a protective frame 1305, a drive gear 1306, and two driven gears 1307. A main stirring rod 1301 is rotatably connected to the center of the upper inner wall of the medicine storage box 3. Auxiliary stirring rods 1302 are rotatably connected to both sides of the upper inner wall of the medicine storage box 3. Multiple T-shaped dispersing rods 1303 are fixedly connected to the outer walls of both sides of the main stirring rod 1301 and the outer wall of one side of the two auxiliary stirring rods 1302. A connecting rod 1308 is fixedly connected to the lower end of the main stirring rod 1301, and a bottom uniform plate 1309 is fixedly connected to one side of the lower end face of the connecting rod 1308. The stirring mechanism 13 enables the medicine in the medicine storage box 3 to be mixed evenly in all directions. That is, the drive motor 1304 drives the main stirring rod 1301 to rotate, and the main stirring rod 1301 drives the two auxiliary stirring rods 1302 to rotate synchronously through the meshing of the drive gear 1306. Multiple T-shaped dispersing rods 1303 rotate with the rod to disperse the agent and water at multiple angles, preventing the agent from clumping. The connecting rod 1308 at the lower end of the main stirring rod 1301 drives the bottom uniform plate 1309 to scrape the bottom of the tank, preventing the agent from settling at the bottom and ensuring a consistent agent concentration inside the tank, laying the foundation for subsequent precise quantitative spraying. At the same time, the protective frame 1305 can isolate the gear set from the agent, preventing the agent from corroding the gears and affecting the transmission. The driving gear 1306 is fixedly sleeved on the upper part of the outer wall of the main stirring rod 1301, and the two driven gears 1307 are respectively fixedly sleeved on the upper part of the outer wall of the corresponding auxiliary stirring rods 1302. The protective frame 1305 is fixedly connected to the upper inner wall of the agent storage tank 3. The driving gear 1306 and the two driven gears 1307 are all movably set inside the protective frame 1305. The driving gear 1306 moves with the main stirring rod 1301. The rotation and meshing of the two driven gears 1307 drive them to rotate synchronously, achieving coordinated rotation of the main and auxiliary stirring rods 1302. This ensures that the stirring range covers the entire agent storage tank 3. The protective frame 1305 encloses the driving gear 1306 and the driven gear 1307, preventing agent splashing and contact with the gears during stirring. This also prevents the agent from corroding the gears or impurities from gear wear from mixing into the agent, extending the service life of the gear set and ensuring the long-term stable operation of the stirring mechanism 13. A drive motor 1304 is fixedly connected to the upper end of the agent storage tank 3. The output end of the drive motor 1304 is fixedly connected to the main stirring rod 1301. By directly connecting the output end of the drive motor 1304 to the main stirring rod 1301, the rotation speed of the main stirring rod 1301 can be precisely controlled to adapt to the stirring requirements of different agents. Compared with manual stirring, motor-driven stirring is less labor-intensive and provides uniform stirring speed, avoiding uneven mixing of agents caused by uneven stirring force. At the same time, the motor operates stably and can operate continuously for a long time, meeting the spraying requirements of large-scale integrated soil management.

[0021] Referring to Figures 2, 4, and 5, the filtration mechanism 14 includes a filter ring 1402. A connecting sleeve 1401 is fixedly connected to the lower end of the corrugated pipe 7 and the upper end of the L-shaped connecting pipe 5. A fixing port 1403 is opened on the upper surface of the filter ring 1402, and a filter screen 1404 is fixedly fitted inside the fixing port 1403. The filtration mechanism 14 can intercept impurities before the agent is delivered. The agent flows from the L-shaped connecting pipe 5 into the lower connecting sleeve 1401, and then passes through the filter screen 1404 inside the fixing port 1403 of the filter ring 1402. The filter screen 1404 effectively intercepts undissolved particles, dust, and other impurities in the agent. The purified agent enters the corrugated pipe 7 through the upper connecting sleeve 1401. The filter ring 1402 connects the corrugated pipe 7 and the L-shaped connecting pipe 5, ensuring a smooth agent delivery path and preventing impurities from entering the water pump 6 with the agent through its filter screen 1404. The flow controller 9 or spray head 11 prevents component blockage and ensures continuous spraying. Annular sealing rings 1405 are fixedly connected to the upper and lower end faces of the filter ring 1402. Annular sealing grooves 1406 are opened on opposite sides of the two connecting sleeves 1401. The two annular sealing rings 1405 are respectively engaged and fitted into the corresponding annular sealing grooves 1406. The annular sealing rings 1405 at the upper and lower ends of the filter ring 1402 engage with the annular sealing grooves 1406 of the corresponding connecting sleeves 1401, filling the connection gap and preventing leakage of the pesticide during delivery. This reduces pesticide waste and prevents leaked pesticide from contaminating the soil or contacting operators, improving operational safety. Simultaneously, the sealing structure maintains stable pesticide delivery pressure, ensuring that the flow controller 9 can accurately control the pesticide flow rate and guarantee quantitative spraying effect. Limiting posts 1408 are fixedly connected to both sides of the upper and lower end faces of the filter ring 1402. One side of each connecting sleeve 1401 has an adjustment groove 1409 at the front and rear. A return spring 1410 is fixedly connected to the inner wall of one side of the adjustment groove 1409. A movable seat 1411 is fixedly connected to one side of the return spring 1410. A locking rod 1412 is fixedly connected to one side of the movable seat 1411. Each of the two connecting sleeves 1401 has a limiting port 1407 at the front and rear of its opposite side. A limiting post 1408 is engaged in the limiting port 1407. Each of the two connecting sleeves 1401 has a locking hole 1413 at the front and rear of its two sides. The locking hole 1413 communicates with the limiting port 1407. The locking rod 1412 is engaged in the locking hole 1413. By pressing the locking rod 1412, the return spring 1410 in the adjustment groove 1409 is compressed. After the limiting post 1408 is fully engaged...The return spring 1410 pushes the locking rod 1412 into the locking hole 1413 of the connecting sleeve 1401, fixing the position of the filter ring 1402. For disassembly, pressing the locking rod 1412 unlocks the filter ring without tools, facilitating regular cleaning or replacement of the filter screen 1404. The cooperation between the limiting post 1408 and the limiting port 1407 also prevents the filter ring 1402 from rotating, ensuring the filter screen 1404 is always in the correct filtration position, improving filtration reliability. Limiting sliders 1414 are fixedly connected to the upper and lower end faces of the moving base 1411. Limiting grooves 1415 are formed on the inner walls of the upper and lower ends of the adjusting groove 1409. The limiting sliders 1414 are slidably positioned within the limiting grooves 1415. When the moving base 1411 drives the locking rod 1412 to move along the adjusting groove 1409, the limiting sliders 1414 at the upper and lower ends move along the adjusting groove 1409. The sliding limit groove 1415 inside the device restricts the movement trajectory of the moving seat 1411, preventing the moving seat 1411 from shifting or tilting. This ensures that the locking rod 1412 is always aligned with the locking hole 1413 of the connecting sleeve 1401, preventing the filter ring 1402 from failing to stay in place due to misalignment. This also prevents the filter ring 1402 from loosening or shifting during operation, ensuring stable filtration and delivery of the pesticide. Universal wheels 2 are fixedly connected to the lower end face of the base plate 1 near the four corners. A control panel 4 is fixedly connected to the front end face of the pesticide storage box 3. The universal wheels 2 at the lower end of the base plate 1 facilitate the movement of the device in the field by the operator, adapting to soil remediation operations in different areas. This eliminates the need for large equipment for transport, reducing workload. The control panel 4 at the front of the pesticide storage box 3 can intuitively display and adjust the start / stop of the water pump 6, the parameters of the flow controller 9, and the speed of the drive motor 1304. Operators can complete various operations without frequently touching the internal components of the equipment, simplifying the work process and improving spraying efficiency. ,

[0022] Working Principle: This precision quantitative spraying device for comprehensive soil remediation ensures uniformity of the pesticide through a stirring mechanism 13 and purifies the pesticide through a filtration mechanism 14. Combined with the conveying and control components, it achieves precise spraying. First, the pesticide is stirred. The drive motor 1304 at the top of the pesticide storage tank 3 is started, and its output drives the main stirring rod 1301 to rotate. The drive gear 1306 on the outer wall of the main stirring rod 1301 meshes with the driven gears 1307 of the auxiliary stirring rods 1302 on both sides, causing the main stirring rod 1301 and the auxiliary stirring rods 1302 to rotate simultaneously. Multiple T-shaped dispersing rods 1303 on both rods thoroughly disperse and stir the pesticide and water in the tank, preventing pesticide clumping. The connecting rod 1308 at the lower end of the main stirring rod 1301 simultaneously drives the bottom uniform plate 1309 to rotate, scraping away the pesticide deposited at the bottom of the tank to prevent accumulation and ensure uniform mixing. Then, the pesticide is filtered and conveyed, and the water pump 6 is started. The agent in the agent storage tank 3 flows into the filter mechanism 14 through the L-shaped connecting pipe 5. The agent first enters the lower connecting sleeve 1401, passes through the filter screen 1404 in the fixing port 1403 of the filter ring 1402, and intercepts undissolved particles, dust and other impurities. The purified agent enters the upper connecting sleeve 1401 and the corrugated pipe 7. The annular sealing rings 1405 at the upper and lower ends of the filter ring 1402 are engaged in the annular sealing grooves 1406 of the corresponding connecting sleeve 1401 to prevent agent leakage. The limiting post 1408 is engaged in the limiting port 1407 and the engaging rod 1412 is engaged in the engaging hole 1413 to ensure that the filter mechanism 14 is firmly connected, and finally achieves precise spraying. The filtered agent is transported to the water pump 6 through the corrugated pipe 7, and then sent to the flow controller 9 on the mounting frame 8 through the water guide pipe 12. The operator sets the spray volume through the control panel 4, and the flow controller 9... After precisely controlling the flow rate of the agent, the agent is delivered to the water storage head 10, and finally sprayed evenly onto the soil through multiple spray heads 11 on one side of the water storage head 10. The device can be flexibly moved by the casters 2 at the bottom of the base plate 1 to adapt to soil treatment operations in different areas, ensuring uniform, pure and quantitative spraying of the agent throughout the process.
