Description

An intelligent staggered linkage pair pendulum type orchard pesticide application device

technical field

The invention relates to the field of modern agricultural plant protection machinery and equipment, in particular to an intelligent staggered linkage pair-swing cylinder type pesticide application device for orchards.

Background technique

With the rapid development of modern agricultural plant protection machinery, spraying plant protection machinery has been greatly improved in terms of automation and intelligence. Of course, the spraying system as a key component must have a corresponding degree of automation and intelligence. At present, the electric control boom spraying system has been launched for the low crop market in the field, which can realize the automatic expansion and folding of the spray boom and the control of the opening and closing of the nozzle through operation, and has been widely used; but for relatively high orchard crops, spraying Rod spraying systems are hardly applicable. After several years of research and development, air-driven orchard spraying systems have been introduced in the market. Although the efficiency of orchard spraying has been improved to a certain extent, the spraying effect, especially for Fruit trees such as hard leaves, dense crowns, arborization and old arborization have poor spraying effects, and at the same time, there are deficiencies in automatic intelligence. The specific problems are expressed as follows:

(1) The spraying of fruit trees is uneven and the spray penetration is poor. At present, the axial flow fan air delivery spraying system commonly used in the market, the air outlet is along the entire circumferential direction of the fan or the baffle is added to block the flow, resulting in divergent, non-concentrated, uneven air volume and low utilization rate. The air outlet close to the air inlet of the fan has a larger air volume, and the corresponding amount of fruit tree leaves is sprayed more, which can basically be sprayed to the inside of the tree canopy; Fruit tree leaves are less sprayed, and even no liquid is sprayed to the fruit tree leaves, let alone sprayed to the inside of the canopy.

(2) The back side of fruit tree leaves cannot be covered with medicine, and the adhesion rate is low. Because the entire circumferential direction of most air-driven spraying systems is an air outlet, it is a single wind direction. During the spraying process, because the air outlet is fixed to the leaves of the fruit tree, the single wind direction makes the front of the leaves facing the air outlet unable to be turned over, resulting in the inability to apply the medicine on the back of the leaves. Although some related manufacturers have produced simple swinging spraying equipment for the problem of spraying in a single wind direction, the spraying efficiency is low due to the swing range, and even missed spraying; because it is not linked to swinging in opposite directions, better wind field deflection cannot be formed. There is still an inability to fully turn over the leaves, and it is impossible to better realize the application of pesticides on the back of the fruit tree. However, the insecticidal and bactericidal application of fruit trees is mainly aimed at the back of the leaves, so the spraying effect is relatively poor.

(3) The spraying cannot be automatically controlled, resulting in a large amount of waste of pesticides. Since the spraying cannot be turned on and off automatically, if it is applied to an automated and intelligent spraying plant protection machine, the spraying system needs to continue spraying, and the spraying is still carried out between the crowns of adjacent fruit trees, single rows of fruit trees and corners, resulting in Great waste of pesticides.

To sum up, many problems in the orchard spraying system are mainly due to the divergence of air volume, fixed and single wind direction, low degree of automation, poor spraying effect, and waste of pesticides. How to concentrate the air volume to improve its utilization rate, realize wind direction deflection, and improve the automation of spraying, so that the uniformity, penetration, and adhesion rate of spraying equipment in orchards are better, the spraying efficiency is higher, and the amount of pesticide waste is lower. It is a technical problem that those skilled in the art need to solve at present.
