Crop under-leaf sprayer - has nozzles outside tubular slotted housing enclosing foliage and supported on wheels or skids

摘要

The under leaf sprayer is supported by a swing arm or parallelogram linkage. For each row of plants there is a partly tubular housing enclosing the foliage, and having in the underside a lengthwise slot. The housing is supported on one or more wheels, skids etc., and the spray nozzles are mounted outside it. There can be several parallel housings at the same intervals as the rows of plants, and each can be adjustable for width, having a bellows at the top to allow this.
