<p>PROBLEM TO BE SOLVED: To provide a spraying device in which spraying holes of uniform pitches can be provided at the bottom of a hopper, and buckling does not occur even when foreign matter is caught between the hopper and a shutter.SOLUTION: A spraying device 1 includes a hopper 4 for fertilizers that can accommodate fertilizers, a plurality of spraying holes 42 provided below the hopper 4 for fertilizers, a shutter 43 for adjusting an opening area of the spraying holes 42, and drive means 5 for sliding the shutter 43. When sliding the shutter 43 to the right side, a lever 52 on the right side is caused to contact a contact part 45 on the right side to pull the shutter 43 from the upstream side, and when sliding the shutter 43 to the left side, the lever 52 on the left side is caused to contact the contact part 45 on the left side to pull the shutter 43 from the upstream side, thereby preventing the buckling due to pulling the shutter 43 from the upstream side at all times.</p> |
