UNIT FOR THE ECOLOGICAL CONTROL OF COLORADO BEETLE AND FERTILIZATION OF POTATO CROPS

摘要

The invention relates to a unit for gathering Colorado beetles and for hoeing and spraying the crop, mounted in connection with a tractor, meant for the mechanization of works in potato crops, which performs, at a single passage, the operations of gathering the beetles, hoeing the field between the rows of the crop and spraying them with ecological liquids containing natural nettle, tobacco and lavender extracts. According to the invention, the unit comprises a framework (1) provided with lifting-lowering system (2) of parallelogram type, a hydraulic cylinder (3), some pipes (4), some hydraulic motors (5), some centrifugal type fans (7) driven by some hydraulic motors (6) from the hydraulic unit and a number of gathering sections (8) which frame the plant rows, and the airstream exhausted through some tubes (9) blows the potato stalks, entraining the adult Colorado beetles and larvae towards a gathering system (10) formed of gathering sacks and boxes, and a combined hoeing and spraying equipment (EPS), mounted behind the tractor, consisting of carried framework (11), on which the hydraulic unit (6), some active elements (12) of ridge plough type for carrying out the inter-row hoeing operation and a spraying installation (13) consisting of a tank, a pump, ana a spraying boom provided with spraying nozzles are mounted.
