Description

Technical Field

[0001] This utility model relates to the technical field of herbicide concentrate dilution devices, and in particular to a herbicide concentrate dilution device. Background Technology

[0002] In modern agricultural production, the use of herbicides is a crucial means of controlling weeds in farmland. To ensure effective weed control and avoid damage to crops, precise dilution of herbicide concentrate is a key step. Currently, most commercially available herbicide dilution devices employ a single-stage dilution method. However, due to the high density and viscosity of herbicide concentrate, it tends to settle and aggregate during single-stage dilution, leading to uneven concentration distribution within the container. This results in excessively high concentrations at the bottom and excessively low concentrations at the top, which not only reduces weed control effectiveness but may also cause phytotoxicity to crops due to locally high concentrations. Furthermore, directly obtaining small doses of herbicide from the concentrate is prone to significant errors, affecting the accuracy of the dilution ratio. Additionally, existing dilution devices are mostly modular, occupying a large area and relying on power equipment for liquid mixing and transportation, resulting in high energy consumption and hindering resource conservation and cost control. Utility Model Content

[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a herbicide concentrate dilution device. This device solves the problem that the liquid cannot be made to flow by gravity and that the herbicide concentrate cannot be diluted again after being diluted. It also solves the problem that the concentrate sinks during a single dilution due to its high density and viscosity, resulting in an excessively high concentration at the bottom and an excessively low concentration at the top. Furthermore, it solves the error when measuring small doses.

Motor 2 9 is fixedly connected to the upper surface of cover plate 1 8 and the lower surface of support plate 28, respectively. A rotating shaft 19 is fixedly connected to the output end of motor 2 9. A stirring blade 20 is fixedly connected to the side surface of rotating shaft 19. A receiving groove 16 is provided on the base 1. The receiving groove 16 is located at the electric motor. Directly below the second part of the machine (9), a main pipe 11 and a branch pipe 18 are respectively connected to the second cover plate 13 and the first cover plate 8. A drug injection pipe 30 is installed on the upper surface of the first cover plate 8. Cleaning devices are installed on the lower surfaces of both the first cover plate 8 and the second cover plate 13. Each cleaning device includes a water tank 3, which is located on the upper surface of the base 1. A liquid pump 17 is fixedly connected to the upper surface of the water tank 3, and the output end of the liquid pump 17 is connected to the main pipe 11. The branch pipe 18 is fixedly connected to the side surface of the main pipe 11 and is also connected to the main pipe 11. Flow meters 10 are installed on both the main pipe 11 and the branch pipe 18. The cleaning device also includes a water ring 21, which is fixedly connected to the lower surface of the first cover plate 8 and is connected to the main pipe 11. Pipe 11 and branch pipe 18 are connected. Spray nozzles 22 are provided on the side surface of water ring 21. Spray nozzles 22 are distributed in a ring around the axis of cover plate 1 8 and cover plate 2 13. Discharge pipe 14 is fixedly connected to the side surface of mixing cylinder 2 12. Discharge pipe 14 is connected to mixing cylinder 2 12. Solenoid valves 15 are provided on discharge pipe 14, main pipe 11, branch pipe 18 and connecting pipe 1 23. Limit plate 29 is fixedly connected to the inner surface of vertical plate 2. Limit plate 29 is located above support plate 28. Control panel 4 is provided on the outer surface of vertical plate 2. Control panel 4 is electrically connected to motor 1 6, motor 2 9, flow meter 10, solenoid valve 15 and liquid pump 17.

[0023] Specifically, during operation, motor 6 is first started via control panel 4. Motor 6 drives screw 26 to rotate, and slider 27 on screw 26 moves within movable groove 25, thereby causing support plate 28 and mixing cylinder 12 to rise. Once mixing cylinder 12 has risen to the appropriate position, the connecting ring is threadedly connected to connecting pipe 23 and connecting pipe 24, connecting mixing cylinder 7 and mixing cylinder 12.

[0024] Next, the solenoid valves 15 on the main pipe 11 and branch pipe 18 are opened. According to the flow meter 10, the liquid pump 17 is controlled to draw a fixed amount of clean water from the water tank 3, which flows into mixing cylinder 7 and mixing cylinder 12 through the main pipe 11 and branch pipe 18 respectively. Then, the herbicide concentrate is injected into mixing cylinder 7 through the injection pipe 30. Subsequently, motor 9 is started, which drives the rotating shaft 19 and the stirring blade 20 to rotate, stirring and mixing the concentrate and clean water in mixing cylinder 7 and mixing cylinder 12. After the initial dilution is completed, the solenoid valve 15 on the connecting pipe 23 is opened to allow the liquid to flow into mixing cylinder 12 for further dilution and mixing.

[0025] After mixing, open the solenoid valve 15 on the discharge pipe 14 to discharge the diluted herbicide from the discharge pipe 14. After use, restart the liquid pump 17 to deliver clean water to the water ring 21 through the main pipe 11 and branch pipe 18. The water is then sprayed through the nozzle 22 to clean the interior of mixing cylinder 7 and mixing cylinder 12. The wastewater from the cleaning process can be discharged through the discharge pipe 14. Throughout the process, the limiting plate 29 is used to limit the height of the support plate 28. The control panel 4 centrally controls the operation of each component, achieving efficient dilution of the herbicide concentrate and convenient cleaning of the device. The receiving tank 16 protects the motor 9 below the support plate 28 when it descends and fits against the base 1.

[0026] Working Principle: During operation, control panel 4 starts motor 6, which drives screw 26 to rotate. The screw 26 and slider 27 are connected by a threaded connection, causing slider 27 to move within the movable groove 25. This, in turn, causes support plate 28 and mixing cylinder 12 to rise. Once at the appropriate position, connecting pipe 23 and connecting pipe 24 are threadedly connected via a connecting ring, connecting mixing cylinder 7 and mixing cylinder 12. Then, solenoid valves 15 on main pipe 11 and branch pipe 18 are opened. Based on feedback from flow meter 10, liquid pump 17 draws a measured amount of clean water from water tank 3, which flows into the two mixing cylinders via main pipe 11 and branch pipe 18. Subsequently, herbicide concentrate is injected into mixing cylinder 7 via injection pipe 30. Next, motor 9 drives rotating shaft 19 and stirring blade 20 to rotate, initially mixing the liquids in the two mixing cylinders. After the initial dilution, open the solenoid valve 15 on the connecting pipe 23 to allow the liquid in the mixing cylinder 7 to flow into the mixing cylinder 12 for further dilution and mixing. After thorough mixing, open the solenoid valve 15 on the discharge pipe 14 to discharge the diluted herbicide. After use, the liquid pump 17 restarts, delivering clean water through the main pipe 11 and branch pipe 18 to the water ring 21. The water is then used to clean the interior of the mixing cylinders 7 and 12 through the nozzle 22, and the wastewater is discharged through the discharge pipe 14. The limit plate 29 restricts the rising height of the support plate 28, and the control panel 4 centrally controls all components to achieve efficient dilution and convenient cleaning. The receiving tank 16 protects the motor 9 when the support plate 28 descends. When water needs to be added to the water tank 3, water can be injected into the water tank 3 through the water inlet pipe.
