Description

Technical Field

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

[0002] Pesticides are mainly used to control crop diseases and pests, improve crop yield and quality, and ensure agricultural production safety. They can kill or inhibit pests, pathogens, and weeds, reducing damage to crops and thus protecting their normal growth. However, pesticides need to be formulated because formulation can improve efficacy. By mixing pesticides with different mechanisms of action, their effects can complement each other. The concentration and combination can be adjusted according to the pest and disease situation. Formulation can also delay the development of pesticide resistance in pests, pathogens, and weeds. By alternating the use of pesticides with different mechanisms of action, the accumulation of resistant individuals can be reduced. In addition, rational formulation of pesticides can reduce the amount of pesticides used while ensuring control effects, thereby reducing production costs and environmental pollution, and minimizing the damage of pesticide residues to the ecological environment.

[0003] A search revealed that the document with publication number "CN218637185U" states that "this utility model relates to the technical field of auxiliary devices for mixing equipment, and in particular to a pesticide mixing device that facilitates mixing, improves work efficiency, and enhances practicality; it includes a mixing box, a stirring mechanism, and a base plate. The mixing box is installed on top of the base plate, and the stirring mechanism is installed on the mixing box. The stirring mechanism includes a support plate, a motor, a first rotating rod, two sets of synchronous wheels, a spur gear, an end-face gear, a second rotating rod, two sets of bevel gears, a stirring rod, and a limiting component.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 As shown, this utility model provides a technical solution: a pesticide mixing device with weighing ratio, including a working chamber 1, a pesticide weighing component 6 installed at the top of the working chamber 1, the pesticide weighing component 6 including a weighing chamber 601 installed at the top of the working chamber 1, a weighing plate 602 installed on the inner side of the weighing chamber 601, a cleaning and stirring component 7 installed on the right side of the weighing chamber 601, the cleaning and stirring component 7 including a drive motor 701 installed on the right side of the weighing chamber 601, and a rotating rod 702 installed at the lower end of the drive motor 701.

[0033] Furthermore, a connecting base 2 is installed on the upper surface of the working chamber 1, and an inlet flow meter 3 is installed above the connecting base 2. The connecting base 2 and the inlet flow meter 3 are connected by a pipe. A water control valve 4 is installed on the upper side of the inlet flow meter 3, and the inlet flow meter 3 and the water control valve 4 are connected by a pipe. An inlet 5 is installed on the right side of the water control valve 4. Under the control of the water control valve 4, the water flows through the inlet 5 into the pipe, flows through the inlet flow meter 3, and enters the working chamber 1 through the connecting base 2. The water inlet volume is controlled by the cooperation of the inlet flow meter 3 and the water control valve 4, so that the water volume can be accurately controlled and the mixing ratio can be precisely controlled when mixing with pesticides.

[0034] Furthermore, the weighing chamber 601 and the weighing plate 602 are a rotating structure. A weight sensor 603 is installed inside the weighing plate 602, and a return spring 604 is installed around the weight sensor 603. There are four sets of return springs 604. When the pesticide enters the weighing chamber 601, it first falls onto the surface of the weighing plate 602. The weight sensor 603 accurately measures the amount of pesticide, so that the ratio can be accurately controlled when it is mixed with water, thereby improving the accuracy of pesticide mixing.

[0035] Furthermore, a cover plate 605 is provided above the weight sensor 603, a connecting shaft 606 is welded to the surface of the weighing plate 602, and a rotating gear 607 is fixedly connected to the surface of the connecting shaft 606. The connecting shaft 606 and the rotating gear 607 are welded together. A rotating motor 608 is provided on the outside of the rotating gear 607. The rotating motor 608 and the rotating gear 607 form a rotating structure through the connecting gear. The rotating motor 608 and the connecting gear drive the rotating gear 607 to rotate. Then, the connecting shaft 606 drives the weighing chamber 601 to flip, so that the weighed pesticide can fall into the working chamber 1 without human control, saving time and effort.

[0036] Furthermore, the drive motor 701 and the rotating rod 702 are connected by a key. A connecting plate 703 is fixedly connected to the surface of the rotating rod 702. A sun gear 704 is mounted on the lower surface of the connecting plate 703. Planet gears 705 are meshed on both sides of the sun gear 704. A gear ring 706 is meshed on the outer side of the planet gear 705. The drive motor 701 drives the rotating rod 702 to rotate, which in turn drives the sun gear 704 to rotate. At the same time, under the action of the sun gear 704 and the gear ring 706, the planet gear 705 is driven to revolve.

[0037] Furthermore, a stirring blade 707 is fixedly connected to the lower surface of the rotating rod 702, and a rotating blade 708 is fixedly connected to the inner side of the planetary gear 705. A connecting rod 709 is installed at the bottom end of the rotating rod 702. The rotating rod 702 and the connecting rod 709 are welded together. A cleaning brush 710 is installed on the surface of the connecting rod 709. The connecting rod 709 and the cleaning brush 710 are bonded together. The rotating rod 702 drives the stirring blade 707 to rotate, thereby mixing pesticides and water. The planetary gear 705 drives the rotating blade 708 to rotate, assisting in the mixing. At the same time, the cleaning brush 710 on the connecting rod 709 brushes the inside of the working chamber 1 during the mixing process. By combining multiple mixing methods, the pesticides and water are ensured to be fully mixed. The cleaning brush 710 can clean the working chamber 1, prevent pesticide residues, and improve the service life of the device.

[0038] Furthermore, a water outlet pipe 8 is installed at the bottom of the working chamber 1, and a water flow meter 9 is installed on the surface of the water outlet pipe 8. When preparing the pesticide solution, the prepared pesticide solution is discharged through the water outlet pipe 8, which facilitates the discharge and collection of the solution. The water flow meter 9 can accurately measure the amount of solution discharged, ensuring that the prepared pesticide solution is used accurately.

[0039] Working Principle: After installing the device in its working position, the water control valve 4 is opened. Water flows into the pipeline through the inlet 5, passes through the inlet flow meter 3, and enters the working chamber 1 through the connecting base 2. The inlet flow meter 3 and the water control valve 4 work together to precisely control the water flow, ensuring that the water volume when mixed with pesticides meets the preset ratio. Pesticides are poured onto the weighing plate 602 of the weighing chamber 601. The weight sensor 603 measures the weight of the pesticides, and the reset spring 604 acts as a buffer and reset mechanism. When the pesticide weight reaches the preset value, the rotating motor 608 starts, driving the rotating gear 607 to rotate via the connecting gear. This, in turn, drives the connecting shaft 606, causing the weighing chamber 601 to flip, and the pesticides automatically fall into the working chamber 1. The drive motor 701 starts, driving the rotating rod 702 to rotate. The rotating rod 702 drives the sun gear 704 to rotate, while the planetary gear 705 revolves under the action of the sun gear 704 and the gear ring 706. The stirring blades 707 on the rotating rod 702 and the rotating blades 708 on the planetary gear 705 work together to stir the pesticide and water in the working chamber 1 to ensure thorough mixing. The cleaning brush 710 on the connecting rod 709 cleans the working chamber 1 to prevent pesticide residue. The prepared pesticide solution is discharged through the water outlet pipe 8. The water flow meter 9 accurately measures the amount of solution discharged to ensure accurate use. This completes the use of a pesticide mixing device with weighing and proportioning.
