PROBLEM TO BE SOLVED: To provide a granular material spraying device for artificial turf, which sprays a plurality of types of granular material on the artificial turf, specifically between a number of piles implanted into a base material of the artificial turf, wherein the device can spray the plurality of types of granular material in predetermined proportions, with good working efficiency. SOLUTION: According to the structure of the granular material spraying device, a carriage 1 moving on the artificial turf C has a hopper 2 mounted thereon. The interior of the hopper 2 is partitioned by partition walls 21 into a plurality of housing chambers 22. Each housing chamber 22 has a discharge port 23 at a lower end thereof, and each discharge port 23 has an adjusting shutter 24 for adjusting the opening degree thereof. Thus the granular material D housed in each housing chamber 22 is discharged from the discharge port 23, and the discharge quantity of the granular material D is adjusted by the adjusting shutter 24.
