Description

Technical Field

[0001] This utility model relates to the field of pesticide emulsion technology, and in particular to a metering device suitable for mixing and metering pesticides in emulsion formulations. Background Technology

[0002] Water-in-oil emulsions (HIEs) are a new type of pesticide formulation. They are formed by dissolving a water-insoluble liquid or solid active ingredient in an organic solvent to obtain a water-insoluble solution, which is then dispersed in water as 0.5-1.5 micrometer droplets. This results in an environmentally friendly pesticide formulation that appears as an opaque white emulsion, a type of oil-in-water emulsion. The production of HIEs requires a mixing and metering device. However, existing devices typically only have a fixed-size stirring rack at the center, which cannot cover the entire mixing chamber, especially in areas where stirring is difficult. There are some inaccessible areas between the mixing rack and the mixing chamber wall. A Chinese patent discloses a "pesticide proportioning and mixing device" with the application number "CN202020587069.X". It can mix pesticides and water evenly through stirring to improve the efficacy of the pesticide. While stirring, it can reduce the vibration force and reduce the vibration effect. However, it cannot solve the problem that there is only one fixed-size mixing rack in the center of the device, which cannot cover all areas of the mixing chamber, especially the problem that some inaccessible areas are formed between the mixing rack and the mixing chamber wall. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a metering device for mixing and proportioning water-in-oil pesticides. A motor rotates a spur gear, causing a gear ring meshing with the spur gear to rotate a rotating table. The rotation of the rotating table causes a stirring frame to stir within the main body of the device, improving the mixing effect of the liquid and ensuring the uniformity of the components. A motor on the rotating table rotates a bevel gear, causing a bevel gear two meshing with the bevel gear to rotate a lead screw. This allows the extension frame threaded to the lead screw to move, changing the stirring range of the stirring frame, promoting uniform mixing, and reducing dead zones.

[0004] This utility model also provides a metering device for mixing and proportioning water-in-oil pesticides, comprising: a device body, a top cover detachably connected to the upper surface of the device body via a snap fastener, a mounting frame fixedly connected to the upper surface of the top cover, a motor I fixedly connected to the inner side of the mounting frame, a spur gear fixedly connected to the output end of the motor I, a gear ring meshing with the outer surface of the spur gear, a rotating platform fixedly connected to the inner wall of the gear ring, a stirring frame fixedly connected to the lower surface of the rotating platform, a motor II fixedly connected to the upper surface of the rotating platform, a bevel gear I fixedly connected to the output end of the motor II, a bevel gear II meshing with the outer surface of the bevel gear I, a lead screw fixedly connected to the inner wall of the bevel gear II, an extension frame threadedly connected to the outer surface of the lead screw, and the stirring frame and the extension frame being located inside the device body.

An identification box is fixedly connected to the outer surface of the main body of the device. An identification plate is placed inside the identification box. The identification plate in the identification box can clearly display the operation instructions and improve the user's operating efficiency.

[0012] Compared with existing technologies, this device for mixing and metering water-in-oil pesticides uses a motor to rotate a spur gear, which in turn rotates a gear ring that meshes with the spur gear, causing the rotating table to rotate. The rotation of the rotating table causes the stirring frame to stir within the main body of the device, improving the mixing effect of the liquid and ensuring the uniformity of the components. A motor on the rotating table rotates a bevel gear, which in turn rotates a lead screw. This allows the extension frame, which is threaded to the lead screw, to move, changing the stirring range of the stirring frame, promoting uniform mixing, and reducing dead zones.

[0022] Specifically, the main body 1 of the device is used to accurately proportion the raw materials and mix them. It mainly consists of a metering pump, a mixing chamber, and a control system. The motor 4 above the upper cover 2 rotates the spur gear 5, which causes the gear ring 6 meshing with the spur gear 5 to rotate the rotating table 7. The rotation of the rotating table 7 causes the stirring frame 9 to stir inside the main body 1 of the device, which improves the mixing effect of the liquid and ensures the uniformity of the components. At the same time, a protective shell 15 is fixed on the upper cover 2 to protect the motor 4, the motor 8, the spur gear 5 and the gear ring 6 from the impact of external debris.

[0023] Reference Figure 3 and Figure 4A motor 8 is fixedly connected to the upper surface of the rotating table 7. A bevel gear 10 is fixedly connected to the output end of the motor 8. A bevel gear 11 is meshed with the outer surface of the bevel gear 10. A lead screw 12 is fixedly connected to the inner wall of the bevel gear 11.

The other end of the lead screw 12 is rotatably connected to the protective shell 17.

[0024] Specifically, the motor 8 on the rotating table 7 rotates the bevel gear 10, which in turn rotates the bevel gear 11 that meshes with the bevel gear 10. The rotation of the bevel gear 11 causes the lead screw 12 to rotate, which allows the extension frame 13, which is threadedly connected to the lead screw 12, to move on the stirring frame 9, thereby changing the stirring range of the stirring frame 9, promoting uniform mixing, and reducing dead zones. The main body 1 of the device is equipped with a protective shell 17 to protect the bevel gear 10 and the bevel gear 11.

[0025] Working principle: During use, the motor 4 above the top cover 2 rotates the spur gear 5, causing the gear ring 6 meshing with the spur gear 5 to rotate the rotating table 7. The rotation of the rotating table 7 causes the stirring frame 9 to stir inside the main body 1 of the device, improving the mixing effect of the liquid and ensuring the uniformity of the components. Then, the motor 8 on the rotating table 7 rotates the bevel gear 10, causing the bevel gear 11 meshing with the bevel gear 10 to rotate. The rotation of the bevel gear 11 causes the lead screw 12 to rotate, allowing the extension frame 13 threadedly connected to the lead screw 12 to move on the stirring frame 9, changing the stirring range of the stirring frame 9, promoting uniform mixing and reducing dead zones.
