Description

Technical Field

[0001] This utility model relates to the field of pesticide mixing technology, and in particular to a pesticide mixing device. Background Technology

[0002] During the application of pesticides, it is usually necessary to use a special mixing device to fully mix the active ingredient with water to ensure uniform concentration of the pesticide solution, thereby improving the spraying effect.

[0003] Existing pesticide mixing equipment generally includes a mixing tank, a mixing mechanism, and a pesticide discharge port, which can basically meet the needs of pesticide mixing and stirring. However, after the pesticide is used, pesticide and sediment often remain on the inner wall of the mixing tank, the surface of the mixing device, and the bottom of the tank. If not cleaned in time, it can easily lead to cross-contamination of the pesticide, imbalance of pesticide efficacy, and even deterioration of pesticide components. Utility Model Content

[0004] The main objective of this invention is to provide a pesticide mixing device that addresses the problems mentioned in the background section.

[0005] To solve the above problems, this utility model proposes a pesticide mixing device, including a mixing tank: a cleaning device is fixedly installed in the upper cavity of the inner wall of the mixing tank. The cleaning device includes a ring pipe and a water inlet. Semi-circular diverter pipes are fixedly installed on both sides of the ring pipe. The top end of the other side of each diverter pipe is fixedly connected to both sides of the water inlet. The rod of the water inlet extends through the mixing tank to the outside.

[0006] The inner circumference of the annular tube is provided with a plurality of first nozzles at fixed intervals, and the bottom circumference of the annular tube is provided with a plurality of second nozzles at fixed intervals.

[0007] In one embodiment, a top cover is fixedly provided at the top of the mixing tank, and a motor is fixedly provided at the center of the top surface of the top cover. The output end of the motor passes through the top cover and extends into the inner cavity of the mixing tank, and a stirring device is fixedly provided at the output end.

[0008] In one embodiment, the stirring device includes a transmission rod and a threaded bolt. Multiple stirring blades are fixedly arranged at 15-degree intervals on the circumference of the transmission rod. A baffle is rotatably mounted at the center of each pair of parallel stirring blades. One side of each stirring blade is fixedly connected to a mounting plate. The top and bottom of the mounting plate protrude outwards. A scraper is rotatably mounted on the inner wall of the mounting plate. A support rod is fixedly mounted within an opening on one side of the scraper. The bottom end of the support rod is rotatably connected to the top surface of the bottom end of the mounting plate. The top end of the support rod is mounted on the inner wall of the top of the mounting plate and threadedly connected to the threaded bolt on the outer wall of the top end of the mounting plate.

[0009] In one embodiment, a plurality of storage tanks are fixedly spaced at the edge of the top cover near the motor. The top of each storage tank penetrates the top cover and extends to its inner wall. A flow valve is fixedly installed at the outlet of each storage tank.

[0010] In one embodiment, a concentration sensor is fixedly installed on the bottom surface of the inner wall of the mixing tank.

[0011] In one embodiment, a control panel is fixedly installed on the middle of one side outer wall of the mixing tank, a discharge port is fixedly installed at the center of the bottom end of the mixing tank, and multiple support legs are fixedly spaced around the bottom circumference of the mixing tank.

[0012] Beneficial effects:

[0013] 1. Input the required formula and measurement through the control panel. The control panel can send an electrical signal to precisely control the flow valves of each storage tank to open proportionally, so that the liquid medicine flows out and automatically enters the mixing tank for mixing, reducing human operation error and ensuring the accuracy of the liquid medicine ratio.

[0014] 2. The stirring device driven by the motor can be automatically started under the control signal. The baffles arranged between the stirring blades can quickly disperse the medicine and fully mix it with clean water, which can significantly improve the stirring efficiency and mixing uniformity. The other side of the stirring blades is equipped with scrapers. The angle of the scrapers can be flexibly adjusted according to the degree of dirt on the inner wall of the mixing tank. During the stirring process, the inner wall is scraped off at the same time, so that the mixing tank is always kept clean and avoids medicine residue and cross-contamination.

[0015] 3. After stirring is completed, the concentration sensor at the bottom of the stirring tank can detect the concentration of the medicine solution in real time and transmit the detection signal to the control panel. If the detection result deviates from the target concentration, the control panel can open the flow valve of the corresponding storage tank again to replenish it, so as to achieve accurate and automated medicine solution ratio.

[0016] 4. After the chemical solution is prepared, the cleaning device can inject high-pressure water through the inlet. The water flows through the diversion pipe into both sides of the ring pipe to ensure that each nozzle in the ring pipe has sufficient pressure. First, multiple second nozzles spaced apart at the bottom form an annular water curtain to thoroughly flush the inner wall of the mixing tank. At the same time, the stirring device is activated, driving the scraper to rotate and scrape off the residue. Subsequently, multiple first nozzles spaced apart around the circumference of the ring pipe use high-pressure jets to thoroughly rinse the stirring blades and the outlet of the storage tank, ensuring that the tank body and the surface of the stirring components are completely clean and guaranteeing the long-term stable use of the equipment.

[0028] The cleaning device 3 is installed in the upper cavity of the inner wall of the mixing tank 1. It is used to rinse the inside of the tank and the mixing components after the proportioning and mixing are completed, so as to keep the inside of the tank clean and avoid drug residue.

[0029] The ring pipe 31, as the core ring pipe of the cleaning device 3, is evenly distributed on the upper part of the inner wall of the mixing tank 1. Its interior is responsible for distributing the high-pressure water flow from the inlet 33 to each nozzle to achieve 360° ring water supply and ensure uniform rinsing.

[0030] The inlet 33 is used to introduce external high-pressure water into the cleaning device 3. Part of its rod penetrates through the mixing tank 1 and extends to the outside, which facilitates connection with the external water source and ensures timely and stable water supply.

[0031] The diversion pipe 32 has a semi-circular structure, with one end fixed to both sides of the ring pipe 31 and the other end fixed to both sides of the inlet 33. It is used to disperse and transmit the water flow from the inlet 33 to both ends of the ring pipe 31, thereby maintaining the water pressure balance in the ring pipe 31 and ensuring that the water pressure of each nozzle is consistent.

[0032] The first nozzle 34 is evenly spaced on the inner circumference of the ring pipe 31, and can use high-pressure water flow to rinse the stirring blade 42 inside the mixing tank 1, the upper part of the tank body and the outlet of the storage tank 7, etc., to ensure that these parts are clean without dead corners.

[0033] The second nozzle 35 is fixed to the bottom circumference of the ring pipe 31 and arranged at even intervals. It can spray downward to form an annular water curtain, which can carry out large-area coverage cleaning of the inner wall of the mixing tank 1. With the rotation of the scraper 44 of the mixing device 4, the inner wall can be quickly flushed and the residue removed.

[0034] To achieve the above-mentioned utility model objectives, such as Figure 1-5As shown, this utility model provides a pesticide mixing device. A top cover 2 is fixedly installed at the top of the mixing tank 1. A motor 6 is fixedly installed at the center of the top surface of the top cover 2.

A baffle 43 is rotatably installed in the middle of two parallel stirring blades 42.

[0035] One side of the stirring blade 42 is fixedly connected to the mounting plate. The top and bottom of the mounting plate protrude outwards. A scraper 44 is rotatably installed on the inner wall of the mounting plate. A support rod 45 is fixedly installed in an opening on one side of the scraper 44. The bottom end of the support rod 45 is rotatably connected to the top surface of the bottom end of the mounting plate. The top end of the support rod 45 is installed on the inner wall of the top of the mounting plate and threadedly connected to the threaded bolt 46 on the outer wall of the top end of the mounting plate. Multiple storage tanks 7 are fixedly spaced near the edge of the top cover 2 close to the motor 6. The top end of the storage tank 7 passes through the top cover 2 and extends to its inner wall. A flow valve is fixedly installed at the outlet of each storage tank 7. A concentration sensor 10 is fixedly installed on the bottom surface of the inner wall of the stirring tank 1. A control panel 5 is fixedly installed in the middle of the outer wall of one side of the stirring tank 1. An outlet 9 is fixedly installed in the center of the bottom end of the stirring tank 1. Multiple support legs 8 are fixedly spaced around the bottom circumference of the stirring tank 1.

[0036] Specifically, the top cover 2 is sealed and installed on the top of the mixing tank 1 to seal the tank body, prevent the liquid from overflowing or contaminating, and also serves as a mounting base for components such as the motor 6 and the storage tank 7.

[0037] The motor 6 is fixed in the center of the top surface of the top cover 2, and its output end passes through the top cover 2 and enters the interior of the mixing tank 1 to drive the stirring device 4 to rotate, providing power for the mixing of the medicine liquid.

[0038] The stirring device 4 consists of a transmission rod 41, stirring blades 42, baffle 43, mounting plate, scraper 44, support rod 45 and threaded bolt 46, and is responsible for achieving rapid and uniform stirring of the liquid medicine.

[0039] The transmission rod 41 is fixedly connected to the output end of the motor 6 and is the central transmission component of the stirring device 4;

[0040] The stirring blades 42 are installed around the transmission rod 41 at fixed intervals of 90 degrees to form a multi-directional stirring surface and increase the stirring coverage area.

[0041] The baffle 43 is rotatably installed in the middle of the adjacent stirring blades 42 to break the direction of liquid flow, avoid the formation of vortex dead angles in the liquid, and thus improve the mixing uniformity;

[0042] The mounting plate serves as a fixed support structure for the stirring blade 42, supporting and connecting the scraper 44 and the support rod 45.

[0043] The scraper 44 is rotatably installed on the inner wall of the mounting plate. During the mixing process, it adheres closely to the inner wall of the mixing tank 1 to scrape off residues or attached dirt and keep the inner wall clean.

[0044] The support rod 45 is fixedly connected to the scraper 44 and rotatably installed on the inner wall of the mounting plate, supporting the rotation of the scraper 44. The bottom end is rotatably connected to the bottom end of the mounting plate, and the top end is connected to the top of the mounting plate through the threaded bolt 46, ensuring that the angle of the scraper 44 can be adjusted as needed.

[0045] The threaded bolt 46 is threaded to the top of the support rod 45 and is used to adjust the angle of the scraper 44 to ensure that the scraper 44 can effectively clean the tank wall under different working conditions.

[0046] Storage tanks 7 are fixed at intervals along the edge of top cover 2 and are used to store different types of pesticide concentrates. The top of the tank penetrates the top cover 2 for easy feeding, and a flow valve is provided at the bottom outlet for precise control of the amount of concentrate added.

[0047] The flow valve is fixedly installed at the outlet of the storage tank 7. It can be opened or closed according to the electrical signal sent by the control panel 5, thereby achieving precise control of the amount of pesticide concentrate added and ensuring the accuracy of the pesticide solution ratio.

[0048] The concentration sensor 10 is fixedly installed at the bottom of the inner wall of the mixing tank 1 to detect the concentration of the liquid in the tank in real time and transmit the detection data to the control panel 5 as the basis for ratio adjustment and replenishment.

[0049] The control panel 5 is fixed in the middle of the outer wall of the mixing tank 1 and serves as the control core of the whole machine. By inputting the required drug formula and ratio parameters, the user can send an electrical signal to control the opening time and opening degree of the flow valve, and at the same time receive the data fed back by the concentration sensor 10 to adjust the ratio in real time.

[0050] The outlet 9 is fixedly located at the center of the bottom of the mixing tank 1, and is used to quickly discharge the medicine solution after the proportioning is completed, so as to facilitate subsequent transportation and use;

[0051] The support legs 8 are fixedly installed at intervals around the bottom circumference of the mixing tank 1 to support and stabilize the entire device, ensuring that the equipment operates smoothly and reliably.

[0052] The specific working process of this device;

[0053] In use, the operator first sets the target mixing ratio parameters through the control panel 5 and selects the type of pesticide to be injected. Driven by the control signal, the flow valves at the bottom of each storage tank 7 open sequentially, allowing different types of pesticide solutions to flow into the inner cavity of the mixing tank 1 according to a preset ratio. After adding an appropriate amount of water, the motor 6 is started. The motor 6 drives the transmission rod 41 to rotate multiple stirring blades 42 synchronously, forming a multi-directional fluid circulation within the tank. The baffle 43 continuously breaks up the liquid eddies during stirring, making the pesticide solution flow more evenly and avoiding sedimentation and dead zones. Simultaneously, the scraper 44 on the mounting plate, with the cooperation of the support rod 45 and the threaded bolt 46, rotates close to the inner wall of the mixing tank 1, effectively scraping away residual liquid adhering to the inner wall and ensuring the integrity of the pesticide mixture within the tank. During stirring, the concentration sensor 10, located on the inner wall at the bottom of the mixing tank 1, monitors the pesticide concentration in real time and transmits the detection signal to the control panel 5. The operator can then readjust the flow valves of each storage tank 7 according to the displayed information to achieve the desired pesticide concentration. Dynamic calibration of liquid concentration; once the liquid solution is prepared and reaches the required concentration, the operator opens the outlet 9 via the control panel 5, and the liquid solution is discharged from the bottom of the mixing tank 1 for easy collection and subsequent use; after the liquid solution is discharged through the outlet 9, the operator injects clean water or high-pressure water through the inlet 33. The clean water is diverted into the ring pipe 31 via the diverter pipe 32, maintaining a stable water pressure inside the ring pipe 31. At this time, the first nozzle 34 on the inner circumference of the ring pipe 31 forms a multi-point impact water flow under high pressure, which can impact the stirring blades 42 and turbulence. The plate 43, scraper 44, and flow valve outlet are subjected to high-intensity rinsing to effectively remove residual chemicals and deposits. At the same time, the second nozzle 35 set on the bottom of the ring pipe 31 sprays a low-pressure water curtain to form a water film that covers the entire inner wall of the mixing tank 1, achieving large-area rinsing. In order to further improve the cleaning effect, the motor 6 can be started at the same time as the clean water is injected, so that the stirring device 4 drives the scraper 44 to rotate. During the rotation, the scraper 44 scrapes off the residual dirt on the inner wall and, together with the water flow, ensures that the inner wall of the mixing tank 1 is clean and free of attachments.
