Abstract

The invention discloses an automatic pesticide mixing device for a vehicle-mounted variable spraying machine. According to a set mixing concentration, quantitative clear water and quantitative pesticide concentrated liquid are drawn through a metering pump, the pesticide concentrated liquid and the clear water are sufficiently and uniformly mixed in a mixing tank and transferred into a buffer tank, and needed pesticide liquid is provided for the spraying machine. The liquid level in the buffer tank and the liquid level in the mixing tank are monitored through liquid level sensors in real time, a system determines whether the pesticide liquid needs to be transferred from the mixing tank or pesticide mixing needs to be conducted again according to the information, the buffer tank is supplemented with the pesticide liquid, and the pesticide liquid is provided for the spraying machine for use. The spraying machine conducts variable spraying including massive spraying, less spraying and zero spraying according to target characteristic information detected by a vehicle-mounted sensor, and the concentration of the mixed pesticide liquid is always constant in the process. Through the automatic pesticide mixing device, the concentration of the mixed pesticide liquid is controlled accurately and intelligently, the probability of contact between personnel and pesticides is reduced, pesticide waste is reduced, and development and popularization of the vehicle-mounted pesticide mixing device are accelerated.

Description

technical field [0001] The invention relates to an automatic drug mixing device, in particular to an automatic drug mixing device for a vehicle-mounted variable sprayer, belonging to the technical field of plant protection machinery spraying. Background technique [0002] my country is a large agricultural country. Spraying pesticides is an effective method to control pests and weeds in nurseries and orchards. As one of the core components of sprayers, the drug mixing device plays an important role in spraying operations. At present, most spray mixing technologies in China are pre-mixed technologies, that is, pesticide concentrates and water are sprayed after manual mixing in the mixing tank. The hidden dangers of personal safety, and the low control precision of the mixing technology, there is a lot of blindness, and the concentration of the mixed liquid cannot be controlled flexibly and conveniently, which may lead to excessive pesticide residues in agricultural products, ...
