SLITTER WORKING TOOL Russian patent published in 1999 - IPC

FIELD: irrigated agriculture, in particular, cutting of narrow slits for cultivating fodder crops. SUBSTANCE: working tool has tine, detachable blades mounted on front part of tine, and chisel mounted on its lower part. Chisel is formed as parallelepiped with blade on its front part and inclined central opening which is aligned with lower part of tine. Tine and chisel junction is formed as dovetail connection. Chisel is further attached to tine by attachment devices, such as mounting pin and fastening bolt, which are inserted into openings in lower part of tine and chisel. Geometric axes of symmetry of openings are extending in parallel one with another or intersect each other. Tine has rigidity rib with mounting opening in upper part for receiving load grip. Such construction allows narrow and supernarrow slits of 15-mm width to be cut and green mass loss to be reduced due to absence of roller which is normally positioned in zone adjacent to slitter casing. EFFECT: reduced draft, increased yield of fodder and other crops and enhanced reliability in operation. 12 cl, 4 dwg
