초록 ▼

Mechanism for dispensing seed or fertilizer for agricultural row crop implements such as seed drills and precision planters. A resilient rotatable roller cooperates with a flat vertical glass dispensing plate to dispense seed or fertilizer from a hopper through a nip between the plate and the roller. A slightly raised narrow slow rate band on the roller cooperates sealingly with a pair of removable confinement flanges so that small seeds such as kale can be confined to the slow rate band and dispensed much more slowly than if the whole width of the roller were used.

대표청구항 ▼

An agricultural implement arranged to be moved along the ground and operative during its movement to deliver seed, fertilizer, or other agricultural particulate materials to the ground, the implement comprising: a hopper extending length-wise transverse to the direction of operative forward motion of the implement, a plurality of outlet openings being formed adjacent the bottom of the hopper, and, a plurality of dispensing mechanisms, one for each said outlet opening respectively, each of said dispensing mechanisms comprising: a dispensing roller fabricated of a resilient material; a flat dispensing plate mounted to cooperate with said resilient dispensing roller in defining a nip which communicates with the associated one of said outlet openings and to which, in use, agricultural particulate material to be dispensed is supplied from said hopper; said resilient dispensing roller being mounted for rotation by a drive and being effective, when rotated, to dispense particulate material through said nip; the dispensing roller being formed on its periphery with a circumferentially extending resilient band which is raised with respect to the adjacent periphery of the roller, said flat dispensing plate being positioned to make tangential contact with said raised band while being spaced from the adjacent periphery of the roller; and each dispensing mechanism further comprising removable particulate material confinement means adapted to be disposed adjacent the hopper outlet opening with which said dispensing mechanism is associated and adapted to cooperate with said raised band on said dispensing roller to confine particulate material to the raised band portion only of the length of said dispensing roller measured in the direction of the axis of rotation of the roller, said removable confinement means comprising a blanking plate adapted to close the said hopper outlet opening, said blanking plate having a smaller sized opening therein to provide communication between said hopper and the raised band portion of said dispensing roller, the underside of said blanking plate having a pair of spaced confinement members, one at each side of said smaller sized opening, extending from said blanking plate toward said dispensing roller and positioned closely adjacent the opposing edges of said raised band respectively, each of said confinement members being shaped to conform to the shape of the portion of the periphery of said dispensing roller adjacent said confinement member; the dispensing roller, upon removal of said removable particulate material confinement means from said hopper outlet opening, being operative to dispense particulate material over a larger portion of the length of the dispensing roller.
