Description

Technical Field

[0001] This utility model relates to the field of drug mixing technology, specifically a drug mixing device for a sprayer. Background Technology

[0002] The core purpose of mixing pesticides used in sprayers is to improve application efficiency and control effectiveness, while simultaneously reducing costs and environmental impact. Multiple pests and diseases often exist in the field, which are difficult to control with a single pesticide. Mixing pesticides with different effects can solve multiple problems at once, reducing the number of applications and saving labor and time costs.

[0003] A drug mixing device for a sprayer, disclosed in patent publication number CN218393167U, includes a stirring rod and a dispensing plate. The sealing cap is removed from the inlet, allowing the liquid to be poured into a storage tank. The sealing cap is then threaded back onto the inlet. A PLC controller controls a motor to rotate the shaft, mounting sleeve, stirring rod, and dispensing plate, thus mixing the liquid inside the storage tank and preventing sedimentation. The drug is then delivered to the spraying device via a delivery pipe. When the level of the drug in the storage tank falls below the level sensor, the sensor sends a signal to the PLC controller, which simultaneously illuminates a warning light to indicate the need for additional drug.

[0004] When the above-mentioned device mixes drugs, it uses a stirring rod to drive the liquid-dispensing plate to rotate and mix the drug solution. However, after the powdered drug is poured into the storage tank, it is very easy for it to clump together. Generally, there is a lot of water in the storage tank. At this time, relying on the liquid-dispensing plate to stir may take a lot of time to mix, resulting in poor mixing effect. In order to solve the above problems, a drug mixing device for a sprayer is proposed. Utility Model Content
