Description

Unmanned aerial vehicle fertilizer injection unit of fruit tree Technical Field The utility model relates to the technical field of fruit tree fertilization, in particular to a fruit tree unmanned aerial vehicle fertilization device. Background In modern agriculture, unmanned aerial vehicle fertilization is used as a high-efficiency and accurate fertilization mode, and has been widely used. Existing unmanned aerial vehicle fertilizer applicators typically include a drug storage tank and spray system for carrying liquid fertilizer. To meet the demands of different types of fertilizers, some devices attempt to dissolve solid fertilizers in water manually or semi-automatically, and direct addition of insufficiently dissolved solid fertilizers may result in solutions containing large amounts of undissolved particles, which, however, tend to clog the pipes and nozzles of the spraying system, affecting the fertilization effect. In addition, the flying height of the fertilization of the fruit trees is large, and in the flying process, the liquid level in the medicine storage box can be fluctuated due to the movement of the unmanned aerial vehicle, so that the balance and the stability of the unmanned aerial vehicle are affected, and particularly, the problem is particularly remarkable when the unmanned aerial vehicle turns or is accelerated rapidly. Disclosure of utility model Aiming at the prior art, the utility model provides the unmanned aerial vehicle fertilizer device for the fruit trees, which realizes the functions of high-efficiency dissolution and stable liquid level of solid fertilizer and remarkably improves the practicability and reliability of the unmanned aerial vehicle fertilizer application operation.
