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.

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.
