Embodiment Construction

[0014] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0015] In addition, for convenience of explanation, three axes of X, Y, and Z which are mutually orthogonal to each other are set in the drawings. The X-axis extends in the front-rear direction of the vehicle (approximately horizontal longitudinal direction), the Y-axis extends in the left-right direction of the vehicle (approximately horizontal horizontal direction), and the Z-axis extends in the vertical direction of the vehicle (approximately vertical direction). The rotation direction around the X-axis is called a swing direction, and the rotation direction around the Z-axis is called a yaw direction.

[0016] figure 1 The shown boom sprayer 1 is an agricultural work equipment that is installed on the front side of a work vehicle (tractor) 90 traveling in a field and is used for spraying an insect pest control liquid (pesticide) from the work vehicle 90 .

Abstract

A boom raising and lowering device 9 is configured to raise and lower a boom 4 that is cantilever-supported on a working vehicle 90. The boom raising and lowering device 9 includes a raising and lowering mount 3 that is provided so as to be able to be raised and lowered with respective to the working vehicle, a roll mount 5 that is provided on the raising and lowering mount so as to be rotatable in a roll direction and that supports the boom in a cantilever-supported manner, a first raising and lowering actuator 30 that drives one end of the roll mount 5 in the vertical direction with respective to the working vehicle 90, and a second raising and lowering actuator 40 that drives other end of the roll mount in the vertical direction with respective to the working vehicle. The boom is driven in the vertical direction and roll direction by operating the first raising and lowering actuator 30 and the second raising and lowering actuator 40.

Description

technical field [0001] The invention relates to a boom sprayer and a boom lifting device. Background technique [0002] JP2004-254526A discloses a boom sprayer. The boom sprayer includes: a boom support frame, which is raised or lowered by a lifting link mechanism arranged on the front side of the work vehicle; a swing shaft, which is arranged on the boom support frame and extends along the front and rear directions; , which is cantilevered on the swing shaft in a rotatable manner; hydraulic cylinder, which is installed between the spray boom support frame and the spray boom; tilt sensor, which is used to detect the tilt angle of the work vehicle; swing angle sensor, which is used to detect The swing angle of the spray boom relative to the spray boom support frame; and the control device, which is used to control the telescopic work of the hydraulic cylinder. [0003] The lift link mechanism is driven by left and right lift cylinders provided on the left and right sides of...
