Row crop weed-killing sprayer - has tanks with separate pumps supplying separate sets of nozzles

摘要

The sprayer is used for weed killing in row crops, and has a number of nozzles at intervals, connected by pipes and a pump to a tank. Two or more tanks are provided, each with its own pump, some of the nozzles being connected to one tank and the remainder to the other. The nozzles can be adjustable vertically and horizontally on a supporting bar, typically via annular holders sliding on the latter and accommodating them in guides holding them in the vertical position. Adjustable guard plates can be mounted on the bar between the nozzles.
