A door-type three-dimensional air-supply sprayer for orchard

Abstract

The invention discloses a door-shaped three-dimensional air-supply sprayer for orchards. The sprayer includes a crawler-type walking system, a door-shaped bracket (15), a spraying system and a spiral three-dimensional air-sending system, wherein the crawler-type walking The system is used to drive the entire sprayer; the door bracket (15) is used to carry and install the spraying system and the spiral three-dimensional air delivery system; the spraying system is used to spray the liquid medicine on the fruit trees; The air exits from the air outlet (21) on the left rear side / or right front side of the canopy and flips the leaves from bottom to top after penetrating the canopy, entering the negative pressure fan and the corresponding wind wind, and again from the air outlet (21) on the right front side / or left rear side of the canopy and turn the leaves from bottom to top to penetrate the canopy and enter the corresponding negative pressure fan and corresponding air duct, forming a circle around Spiral airflow in the canopy. The sprayer of the invention can enhance the rolling degree of the blades and improve the spraying effect.

Description

technical field [0001] The invention belongs to the technical field of agricultural plant protection machinery, and in particular relates to an orchard air-fed sprayer, in particular to an orchard door-shaped three-dimensional air-fed sprayer capable of realizing spiral air blowing. Background technique [0002] The orchard door-type three-dimensional air-supply sprayer adopts the air-supply mode. The negative-pressure fan generates a strong airflow to blow the mist to various parts of the fruit tree, which promotes the leaf turning, improves the adhesion rate of the liquid medicine, and is not easy to damage the branches of the fruit tree or damage the fruit. Existing orchard air-supply sprayers mostly adopt single-side diffuse spraying technology, which are applied to standard air-supply sprayers, high-tower air-suspended sprayers and multi-arm air-sent sprayers, and are used in branches and leaves in my country. In dense low-rise densely planted orchards, the inherent thre...

Problems solved by technology

Existing orchard air-supply sprayers mostly adopt single-side diffuse spraying technology, which are applied to standard air-supply sprayers, high-tower air-suspended sprayers and multi-arm air-sent sprayers, and are used in branches and leaves in my country. In dense low-rise densely planted orchards, the inherent three-dimensional structure of the canopy makes it difficult for the droplets to deposit on the inner chamber and the back of the leaves, and the drift is more serious. The tunnel-type pesticide application technology that emerged later semi-enclosed the crops in a trihedral space. The use of the liquid holding tank to achieve recovery and adjustable width improves the deposition effect of the liquid on the front of the leaves to a certain extent and reduces the drift of pesticides. However, the deposition of the liquid on the back of the leaves, which is often an area where diseases and insect pests frequently occur, is still insufficient, and tunnel spraying Machine size adjustment is limited to width adjustment, only suitable for some trellis orchards
