<p>PROBLEM TO BE SOLVED: To appropriately perform application work under control of a number of revolutions of a delivery roll interlocked with a working speed of a vehicle body by starting the work after checking and setting a current accurate actual application amount of material to be applied in a hopper delivered by the delivery hopper.SOLUTION: A GPS vehicle-speed-interlocked application system comprises: an applicator A1 including a hopper 1, a delivery roll 2, and a drive motor 3; a GPS receiver A2 for receiving working speed information of a vehicle body B1 from GPS; and a control device A3 for controlling a number of revolutions of the delivery roll 2 interlocked with the working speed of the vehicle body B1 from the GPS receiver A2. The control device A3 includes: low-speed amount adjusting means 11 and high-speed amount adjusting means 12 that rotate the delivery roll 2 at a low speed and a high speed for preset numbers of revolutions for prescribed times, respectively; and actual application amount calculation means 13 that calculates an actual application amount per application hour from a total application amount of material to be applied M per area of a field by inputting respective measurement values for the low-speed rotation and the high-speed rotation that are acquired by a weighing instrument D from respective delivery amounts of the material M to be delivered from the current applicator A1 by the low-speed amount adjusting means 11 and the high-speed amount adjusting means 12.</p> |
