Problems solved by technology

At present, pesticides are mixed manually in plant protection operations. Due to uneven manual mixing, the mixing accuracy cannot be guaranteed, which will lead to large errors in the dilution of pesticides, waste pesticides, and affect the operation effect. Not only that, improper operation of manual mixing of pesticides will bring great pollution to the environment, and will also cause harm to the health of workers
[0003] Nowadays, the operation of plant protection drones is developing rapidly and widely, and there is an urgent need for a pesticide mixing device. Some manufacturers have realized this problem and produced pesticide boxes. However, the existing pesticide boxes can only be mixed manually, with single functions and relatively high precision. Low, unable to meet the operation requirements of plant protection drones

Embodiment 1

[0056] Such as Figure 1 to Figure 6 As shown, the present embodiment provides an automatic pesticide mixing device, which includes a water tank 1, a chemical mixing box 2, a pesticide box 3 and a main controller 4, and the automatic pesticide mixing device of this embodiment is applied to spraying equipment (such as plant protection drones, etc.) in spraying operations.

[0057] The water tank 1 has a water inlet and a water outlet, and the water outlet of the water tank 1 is connected with the water inlet of the mixing tank 2 through the pump water pipe 5 to provide clear water for the mixing tank 2; in order to prevent water from overflowing from the water inlet of the water tank 1 , The water inlet of the water tank 1 of this embodiment is provided with a water inlet cover 101 .

[0058] Further, the water tank 1 is provided with a first liquid level sensor 102 and a water quality sensor 103. The first liquid level sensor 102 and the water quality sensor 103 are connected...

Embodiment 2

[0079] Such as Figure 12 with Figure 13 As shown, the difference between the pesticide automatic mixing device of this embodiment and Embodiment 1 is that: the outside of the mixing box 2 and the pesticide box 3 is provided with a third shield 9, and the third shield 9 can protect the mixing box. 2 and the pesticide box 3, the second shield 9 and the water tank 1 form a square structure respectively.

Embodiment 3

[0081] Such as Figure 14 As shown, the difference between the pesticide automatic mixing device of this embodiment and Embodiment 1 is that: the outside of the mixing box 2 and the pesticide box 3 is provided with a third shield 9, and the third shield 9 can protect the mixing box. 2 and the pesticide box 3, the third shield 9 and the water tank 1 form a cylindrical structure respectively.

Abstract

The invention discloses a device for automatically blending pesticides and a control method. The device comprises a water tank, a pesticide mixing tank, a pesticide box and a master controller; a water outlet of the water tank is connected with a water inlet of the pesticide mixing tank through a pump water pipe; a pesticide outlet of the pesticide box is connected with a pesticide inlet of the pesticide mixing tank through a pesticide feeding pipe; a pesticide feeding channel is arranged on the upper end of the pesticide mixing tank; the pesticide outlet of the pesticide mixing tank is connected with a pesticide tank of a spraying device through a pump pesticide pipe; the master controller is used for controlling the volume of pesticides conveyed into the pesticide mixing tank through thepesticide box, the volume of clean water conveyed into the pesticide mixing tank through the water tank, the blending of pesticides in the pesticide mixing tank and the volume of pesticide liquor conveyed to the pesticide tank of the spraying device through the pesticide mixing tank. Pesticide water separation, real-time blending, sufficient mixing and accurate ratio are adopted by the device, sothat the dosage of pesticides and the inflow volume of clean water in the pesticide mixing tank can be effectively controlled and the dilution ratio and the pesticide concentration can be accuratelymeasured.

Description

technical field [0001] The invention relates to an automatic pesticide mixing device and a control method, which can be used for the automatic mixing of pesticides during the spraying operation of plant protection spraying equipment, especially agricultural automatic mixing of agricultural aviation drones for plant protection operations, and belongs to the field of pesticide mixing. Background technique [0002] At this stage, the prevention and control of diseases and insect pests in my country's agriculture and forestry mainly depends on the chemical control of pesticides, and most pesticide formulations need to be diluted with water and prepared to a certain concentration before use, especially the dilution of pesticides required for plant protection UAV flying defense operations . At present, pesticides are mixed manually in plant protection operations. Due to uneven manual mixing, the mixing accuracy cannot be guaranteed, which will lead to large errors in the dilution o...
