Automatic profile modeling sprayer applicable to citrus orchard terrain

Abstract

The invention belongs to the technical field of agricultural machinery and relates to an automatic profile modeling sprayer applicable to citrus orchard terrain. The automatic profiling sprayer consists of a spraying operation part, a lifting guide rail part and a carrier part, wherein the spraying operation part is divided into a left side and a right side, and mechanisms at the two sides are exactly of the same dimension; spraying operation is carried out by upper and lower spray rods, the upper spray rod is used to carry out profile modeling spray on the surface of a citrus tree canopy, andthe lower spray rod is used to carry out profile modeling spray inside the canopy layer; a guide rail device enables the spraying operation devices at the left and right sides to move laterally; a lifting mechanism is mainly driven by hydraulic push rods, and the hydraulic push rods are arranged in a triangular shape, so that the angle of the spraying operation part can be adjusted in real time while the height is adjusted, and furthermore, the spraying operation part can maintain a certain angle relative to the horizontal plane in complex terrain; with a crawler type chassis, the sprayer hasthe characteristics of stable operation, adaptability to wide terrain and the like.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to an automatic profiling sprayer suitable for the topography of citrus orchards. Background technique [0002] The structure of the spraying device is various, and the spraying device usually includes a liquid medicine device, a spray rod communicated with the liquid medicine, a spray rack connected to the end of the spray rod and a spray nozzle arranged on the spray rack. Because citrus and other similar large crown fruit trees have the characteristics of large canopy and dense leaves, a series of spraying machines have been designed at home and abroad. There is a tunnel-type fruit tree spraying device in Taiwan, which is composed of a profiling spray frame similar to the gantry type and a plurality of nozzles installed on the frame. Israel also designed a similar spraying device, which has higher spraying efficiency than conventional spraying devices, ...

AI Technical Summary

Problems solved by technology

The invention patent fails to spray the canopy of fruit trees, the overall quality of the machine is relatively large, and the material requirements are high; due to its large degree of wrapping, it is impossible to change the canopy shape of different fruit trees in time; the economy is poor;

[0005] Chinese patent CN106622773A discloses a profiling boom of a sprayer and its control method. This patent is to carry out profiling spraying operations by adjusting the spray racks on both sides. Adjusting the structure requires a lot of motors; due to the characteristics of the mechanism, it is difficult to adapt to the complex terrain operating environment
