SECTIONAL BOOM HEIGHT CONTROL OF INDIVIDUAL SECTION FOR SPRAYERS AND SYSTEM THEREOF

摘要

A spray boom of a spray boom assembly (112) includes a boom frame (124, 126, 128, 130, 132, 134, 136) and a spray section (204, 206, 208, 210, 420, 422, 424, 426, 428, 430, 436, 438, 440, 442, 500, 604, 606, 608, 704, 706, 708) coupled to the boom frame (124, 126, 128, 130, 132, 134, 136). The spray section (204, 206, 208, 210, 420, 422, 424, 426, 428, 430, 436, 438, 440, 442, 500, 604, 606, 608, 704, 706, 708) includes an elongated spray pipe (212, 504, 610, 612, 710, 712, 714) configured to be fluidly coupled to a fluid source (110) and a nozzle (116, 214, 506, 616, 618, 620, 716, 718, 720) coupled to the spray pipe (212, 504, 610, 612, 710, 712, 714). An actuator is coupled at one end to the boom frame (124, 126, 128, 130, 132, 134, 136) and at an opposite end to the spray section (204, 206, 208, 210, 420, 422, 424, 426, 428, 430, 436, 438, 440, 442, 500, 604, 606, 608, 704, 706, 708). The actuator controllably extends and retracts to move the spray pipe (212, 504, 610, 612, 710, 712, 714) and nozzle (116, 214, 506, 616, 618, 620, 716, 718, 720) between a raised position and a lowered position.
