<P>PROBLEM TO BE SOLVED: To provide a control working vehicle for spraying chemicals, which can stably obtain spraying speed with high degree of accuracy in order to perform proper chemical spraying by spraying of a prescribed amount of chemicals per unit area. <P>SOLUTION: The control working vehicle for chemical spray includes: a front wheel 3 and a rear wheel 4 which support the machine body to be travelable in the farm; and a vehicle speed interlocking spraying apparatus D which performs chemical spray of the chemical amount of a prescribed amount per unit area by a control part C which control the spray amount by the spraying vehicle speed as an interlocking standard. The control working vehicle for chemical spray also includes: a driving sensor S1 which detects driving operation of the front wheel 3 and rear wheel 4; a GPS sensor S2 which detects a machine body position by receiving GPS radio wave; and a storing part C1 which controls the spraying amount of the vehicle speed interlocking spraying apparatus D by moving speed of the machine body obtained by the GPS sensor S2 as the spraying vehicle speed, and obtainably holds the slip ratios of the front wheel 3 and the rear wheel 4 computed from the difference between the driving speed of the machine body obtained by the driving sensor S1 and the above moving speed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
