Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a feeding device such as a fertilizer spreader, and can be used as a fertilizer roll that feeds out seeds while adjusting the amount of fertilizer applied. It can be used as a fertilizer application device for machines, or as a feeding device for feeding out other granular materials.

Prior Art and Problems to be Solved by the Invention In order to control the seeding rate of the seeding roll to 18 knots, a grooved roll is provided with feeding grooves on its rotating circumferential surface, and each of these feeding grooves is slidable from the axial direction. In the form of an adjustment roll equipped with an adjuster that adjusts the axial length of the feed groove by fitting into the adjustment roll, each adjuster of the adjustment roll has an automatic end in the circumferential direction. Since the adjuster is separated into a brush-like shape, during the feeding operation, the adjuster easily floats up from the feeding groove to the outer periphery and deforms. In particular, when adjusting the adjustment roll by means of a screw in the axial direction, when the screw is still rotatable, the adjuster moves to narrow the axial width of the feed groove by the rotational transmission of the feed roll. The free end is likely to hit and deform.
