<P>PROBLEM TO BE SOLVED: To provide a tractor-mounted boom sprayer capable of controlling rotation of the boom rapidly and appropriately to correct the inclination angle rapidly when a boom is inclined actually. <P>SOLUTION: The boom sprayer includes a boom rotation means 8 for supporting the boom 4 in a freely rotatable way in the vicinity of the center of gravity of the base frame 3 and rotating the boom 4 in one or the reverse direction, a front wheel inclination angle measurement means 9 for measuring the inclination angle of the front wheel 24 relative to the body 21, a boom rotation preparation control means 11 for causing the boom rotation means 8 to prepare for rotating the boom 4 in the direction opposite to the direction of the relative inclination angle of the axis of the front wheel before the rear wheel is inclined owing to bumpiness of the running surface, a boom inclination angle measurement means 10 for measuring the inclination angle of the boom 4 relative to the base frame 3, and a boom rotation control means 12 for controlling the boom 4 by driving the boom rotation means 8 being preparing for rotation when the relative inclination angle of the boom 4 exceeds a predetermined range. <P>COPYRIGHT: (C)2013,JPO&INPIT |
