Problems solved by technology
In the prior art, when carrying out spraying operations with different concentrations, different batches of pesticides with different concentrations need to be carried on the plant protection drones and then sprayed. Inject another concentration of liquid medicine into the container. In addition, the drone needs to rise and fall multiple times, and repeatedly fly over some plots to generate a large number of invalid trips; the test cost is high and the efficiency is low

Embodiment Construction
[0018] The present invention will be further described below in conjunction with accompanying drawing of description and embodiment:
[0019] Such as figure 1 A switchable pesticide mixing device suitable for plant protection drones is shown, including a liquid storage tank 1, a liquid supply tank 2, a mixing tank 3, and a buffer tank 4; the inside of the liquid storage tank is divided into first The partition 13 of the chamber 11 and the second chamber 12; the liquid supply tank 2 is provided with a liquid taking chamber 21 parallel to each other and two liquid distribution chambers, namely the first liquid distribution chamber 22 and the second liquid distribution chamber 23; Both the liquid chamber and the liquid distribution chamber are provided with a piston 5 that can move longitudinally. The driving mechanism 6, the longitudinal movement driving mechanism drives the pistons to move synchronously in the liquid taking chamber or the liquid distribution chamber; the side ...

The present invention relates to a ratio-switchable pesticide mixing device suitable for plant protection drones, including a liquid storage tank, a liquid supply tank, a mixing tank and a buffer tank; injecting a high-concentration liquid medicine into the first chamber of the present invention, The second chamber is filled with water or an aqueous solution of additives, and the ratio of the liquid in the first chamber and the liquid in the second chamber that enters the mixing tank is controlled by opening and closing the valve, so that three kinds of ratios can be mixed in the mixing tank In actual operation, the weight of the liquid storage tank and its internal liquid is much greater than the weight of other components such as the liquid supply tank and the mixing tank, which will not significantly increase the load of the drone, and the internal space of the mixing tank and the buffer tank Smaller, setting a narrow transition zone between different test plots can spray a predetermined concentration of chemical solution on the target plot, without stirring different concentrations of chemical solutions in batches and without heavy loads to run a large number of invalid strokes.
Description
technical field [0001] The invention relates to a ratio-switchable pesticide mixing device suitable for plant protection drones. Background technique [0002] Due to the continuous outbreak of rice pests, the amount and frequency of pesticide application in rice fields have increased sharply, and the safety of rice has attracted attention. On the one hand, chemical residues are related to pesticides, and more importantly, they are caused by unscientific application of pesticides and outdated pesticide application technology and equipment. In order to explore scientific methods and suitable pesticide application in a scientific time, it is necessary to study aviation pesticides Low-volume spraying techniques in spraying operations, the deposition of pesticides on rice leaves, and the changes in pesticide residues between high-concentration and reduced aerial spraying methods and conventional spraying methods were studied to study the effects of the two operation methods on ri...
