Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] Please see Figure 1 and Figure 2 This embodiment provides a pesticide quantitative filling device, including a fixed plate 1, a movable plate 2, and a pipette 3. The fixed plate 1 is used to fix other components, the movable plate 2 is used to drive the pipette 3 to move, and the pipette 3 is used to quantitatively transfer pesticide.

[0020] Multiple pipettes 3 are arranged side by side. Each pipette 3 includes a pipette tube 3a, a piston 3b, and a push rod 3c. The piston 3b is located inside the pipette tube 3a and is slidably connected to it. One end of the push rod 3c is fixedly connected to the piston 3b, and the other end is connected to a moving plate 2. One end of the pipette tube 3a is connected to a fixed plate 1, and the other end has an opening for liquid inlet and outlet. Specifically, each pipette 3 also includes an inlet tube 3d, an outlet tube 3e, an inlet check valve 3f, and an outlet check valve 3g. The inlet tube 3d is connected to the opening of the pipette tube 3a, and the inlet check valve 3f is provided on the inlet tube 3d. The inlet check valve 3f allows the liquid in the inlet tube 3d to flow unidirectionally to the pipette 3. The outlet tube 3e is connected to the delivery ends of the multiple pipettes 3 respectively, and the connection points are each provided with an outlet check valve 3g. The outlet check valve 3g allows the liquid in the outlet tube 3e to flow unidirectionally to the outlet end. When the push rod 3c moves a certain distance, the inner diameter area of ​​the pipette 3a is directly proportional to the amount of pesticide absorbed and released. Therefore, when mixing multiple pesticides, pipettes 3a with different diameters can be set according to different pesticide ratios for pipetting. The ratios of different pesticides are equal to the ratio of the cross-sectional areas of the pipettes 3a.

[0021] The movable plate 2 is connected to the push rods 3c of multiple pipettes 3. The movable plate 2 moves to simultaneously push the multiple push rods 3c to move simultaneously. Preferably, the pesticide quantitative filling device also includes a drive unit 5, which is connected to the movable plate 2 to drive the movable plate 2 to move. More preferably, the drive unit 5 is a cylinder, with its fixed end fixedly connected to the fixed plate 1 and its movable end fixedly connected to the movable plate 2. More preferably, the surface of the fixed plate 1 has a protrusion forming a connecting part 1b, and a limiting bolt 6 is set along the moving direction of the push rod 3c. The limiting bolt 6 is threadedly connected to the connecting part 1b, and the limiting bolt 6 can abut against the movable plate 2 to restrict the movement of the movable plate 2. This ensures that the path length of the movable plate 2 is fixed for each round trip, further ensuring that the amount of pesticide absorbed and released by the pipette 3a is constant, thus achieving quantitative filling.

[0022] Preferably, the pesticide quantitative filling device further includes fixing pins 4, with a fixing port formed between two adjacent fixing pins 4. Multiple fixing pins 4 are fixedly connected to the fixing plate 1. A fixing part 3aa extends outward from the end of the pipette 3a near the moving plate 2. The fixing part 3aa is disposed in the fixing port to limit the movement of the pipette 3a along the direction of the push rod 3c. More preferably, the fixing plate 1 has multiple fixing holes 1a, and the fixing pins 4 can be connected to different fixing holes 1a to change the position of the fixing port. When it is necessary to replace the pipette 3 with a different diameter, the size of the fixing part 3aa may also be different. The two ends of the fixing part 3aa are respectively in two fixing ports, and changing the position of the fixing port can accommodate pipettes 3 with different diameters.

[0023] Preferably, the movable plate 2 has multiple connecting grooves 2a, and the end of the push rod 3c away from the piston 3b extends to the side to form a pushing part 3ca. The pushing part 3ca is embedded in the connecting groove 2a, thereby facilitating the replacement of different pipettes 3.

[0024] Preferably, the side of the pipette 3a is provided with graduation lines to facilitate observation of the volume of liquid drawn and dispensed by the pipette 3.

[0025] In summary, the pesticide quantitative filling device provided in this application uses pipettes 3a of different diameters to simultaneously absorb different pesticides. When the moving plate 2 drives the push rod 3c to move, the ratio of different pesticides absorbed and released is the same as the ratio of the cross-sectional area of ​​the pipette 3a, thereby realizing proportional dispensing. By controlling the moving path of the moving plate 2, the dispensing volume can be controlled, thus realizing quantitative dispensing of pesticides.

Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
