Spraying device and spraying system for fruit forest

Abstract

The invention discloses a spraying device and spraying system for a fruit forest. The spraying device comprises a bracket and multiple nozzles; the multiple nozzles are installed on the bracket, and capable of all covering a fruit tree with medicine liquid from the crown to the bottom while spraying in a manner of adjusting the injection angle; the spraying system comprises a medicine liquid source, a liquid pumping power device and the spraying device; and the output end of the liquid pumping power device is communicated with the liquid inlet ends of the nozzles through a pipeline. Accordingto the spraying device and spraying system for the fruit forest in the invention, due to arrangement of the nozzles different in injection angle, the fruit tree can be sprayed with the medicine liquidfrom top to bottom, from back to face and from outside to inside, so that there is no place for pests to hide; simultaneously, the fruit tree can be sprayed with the medicine liquid from inside to outside at the same time; furthermore, 60% pesticides can be saved; the medication cost is reduced; the pesticide amount in the environment is reduced; furthermore, the spraying device in the inventionis simple in structure, high in operability and free from complex operation step, and cannot be influenced by roads and land forms; and spraying can be carried out in any place where people can walk.

Description

technical field [0001] The invention relates to the technical field of gardens, in particular to a pesticide spraying device and a pesticide spraying system for fruit forests. Background technique [0002] The existing orchard spraying methods are mainly three types: artificial boom spraying, self-propelled air-driven mechanical spraying and helicopter spraying. [0003] Artificial boom spraying is to pressurize the liquid medicine through the medicine pump and then use the pipe to transport it to the nozzle. Although the efficiency and quality of this spraying method are greatly improved compared with the knapsack sprayer, in Chenglin Orchard, a worker can only For an orchard of 2 to 3 mu, the operating efficiency is low and the time cost is high; the labor cost of spraying is high, and it takes a lot of labor to spray an orchard; at the same time, it is difficult to spray the liquid evenly on the leaves, backs, and inside and outside of the fruit trees. , leading to repea...

[0003] Artificial boom spraying is to pressurize the liquid medicine through the medicine pump and then use the pipe to transport it to the nozzle. Although the efficiency and quality of this spraying method are greatly improved compared with the knapsack sprayer, in Chenglin Orchard, a worker can only For an orchard of 2 to 3 mu, the operating efficiency is low and the time cost is high; the labor cost of spraying is high, and it takes a lot of labor to spray an orchard; at the same time, it is difficult to spray the liquid evenly on the leaves, backs, and inside and outside of the fruit trees. , leading to repeated spraying of most of the medicinal liquid on the outermost leaf surface, not only the waste of medicinal liquid is large, but also the spraying effect is poor, and the human factors are greatly different.

[0004] Since the ground of the orchard is equipped with drainage ditches, the self-propelled air-driven spraying machine is limited by the terrain and roads, so it is difficult to realize the mechanization of spraying in the orchard

At the same time, the air-driven spraying machine consumes diesel or gasoline, which not only consumes non-renewable resources, but also is not clean energy, which is not friendly to the environment

[0005] Although helicopter spraying is efficient and not affected by roads, its use concentration is 20 times that of other spraying methods, which is prone to phytotoxicity, and it cannot spray pesticides on the inner hall and back of fruit trees; and many pests live on the back of leaves hiding, especially from mites

Even if the leaves are sprayed with liquid medicine by blowing air to the leaves to increase the turning of the leaves, the effect is limited, and it is limited to the leaves at the top of the tree, and the effect of spraying the liquid medicine on the bottom of the tree and the inner hall is poor.
