APPLICATOR FOR PARTICULATE MATERIAL

摘要

APPLICATOR FOR PARTICULATE MATERIAL A manually operated applicator for distributing controlled quantities of particulate fertilizer or pesticide to container-grown ornamentals. The applicator comprises a hopper, an elongated discharge conduit extending below the hopper and a control means located in the upper part of the discharge conduit for precise control of the quantity of particulate material distributed from the applicator. The control means comprises one or more rotors horizontally mounted for rotation within a cylindrical housing, the rotors containing cavities therein for metering the amount of particulate material. The rotor is spaced from the housing to form an annular clearance to permit a small but controlled quantity of particulate material to enter the clearance. The rotor is mounted on a shaft journaled on bearings at both ends, one of the bearings being axially adjustable to accommodate varying numbers of rotors or rotors of varying axial thickness. The rotors are manually cranked by a suitable arm attached to the shaft.
