Description

A kind of air-driven pesticide application mechanism for large-scale spraying

Technical field

The utility model relates to the technical field of agricultural pesticide application mechanisms, and in particular to a wind-driven pesticide application mechanism for large-scale spraying.

Background technique

In the process of planting fruit trees, it is often necessary to spray pesticides on the fruit trees. Since the spraying process requires upward spraying, the mist spreads around the sprayers, so the working environment is relatively harsh. In order to reduce the damage to labor caused by spraying operations, spraying machines are currently being used. Gradually popularized. The air-driven pesticide application mechanism is the core part of the pesticide application machine. In the existing technology, the patent CN108353874A discloses a typical sprayer. This sprayer sprays more concentratedly and has a small spray range. When used in orchards, frequent control is required for pesticide spraying. its rotation. In the patent CN213939455U, in order to obtain a larger spraying range, a larger shelf needs to be built to disperse the spray heads, resulting in a larger overall volume, easy obstruction by branches, and poor applicability.

The air outlet on the fan cover includes a first air outlet and a second air outlet; the shape of the first air outlet is square or circular, and a plurality of atomizers are arranged on the outline of the first air outlet. Composite arrangement within the range; the shape of the second air outlet is a long strip, and a plurality of the atomizers are arranged equidistantly on the extension line of the second air outlet; viewed in the axial direction of the fan blades , the air outlet range of the first air outlet is staggered from the air outlet range of the second air outlet.

In actual use, the entire inclination angle of the first air outlet relative to the ground is greater than the inclination angle of the part with the largest inclination in the second air outlet. Since the outline shape of the first air outlet is a compact shape such as a circle or a square, and the atomizers within its outline are arranged in a concentrated manner, it can produce a stronger and denser spray of medicine, which can help the medicine overcome gravity and be sprayed to a larger area. High branches and leaves, and be able to fully turn the branches and leaves to spread the medicinal mist throughout the blocked branches and leaves. Since the second air outlet is strip-shaped and the atomizers within its outline are arranged in a scattered manner, it can spray within a larger angle range and is suitable for better spraying and spraying on the side and above the side. The sprayed liquid does not need to overcome great resistance to reach the branches and leaves for spraying.

The above-mentioned composite layout structure can meet the spraying characteristics of the orchard, fully spray the branches and leaves of the fruit trees, and achieve good spraying effects.

Further, the first air outlet and the second air outlet are staggered in the axial direction of the fan blade. This can facilitate air distribution and prevent internal air flow turbulence from causing insufficient wind power at the first air outlet.

Further, the space in the fan casing is divided into two air chambers by an annular partition, which are a first air chamber and a second air chamber respectively; the fan blades are respectively installed in the two air chambers; The first air outlet and the second air outlet are connected with the first air chamber and the second air chamber respectively.

Further, the ventilation holes are arranged along the axial direction of the fan blade, and the ventilation holes and the air duct are connected through pipes. The duct guides the air discharged from the axially arranged vent holes to the circumferentially arranged air ducts. Compared with the scheme in which the second air cavity is directly connected to each air duct, it can avoid the weakening of the wind caused by the extension length of the second air outlet being too long. And the problem of uneven wind speed in each air duct.

Furthermore, the cross-section of the air guide duct gradually decreases in the direction away from the second air cavity, which can achieve a wind gathering effect, increase the wind speed of the vent hole, and ensure the mist delivery effect.

Beneficial effects: The large-scale air-driven pesticide application mechanism of this utility model arranges the atomizers in air outlets of different shapes in different arrangements, which can meet the air outlet requirements of different fruit trees at different positions and meet the pesticide application requirements in orchards. Characteristics: fully apply pesticides to the branches and leaves of fruit trees, and the pesticide application effect is good. In addition, the air-fed pesticide application mechanism has a compact structure, small volume, and good applicability.
