Abstract
A beet topping device transportable over the ground, comprising a frame, a polygonal construction, in particular a quadrangular construction or quadrangular linkage movably connected to the frame, via at least one pivot shaft and variable in position relative thereto, a blade holder connected movably relative to the frame via a feeler arm in a first point of application to the quadrangular linkage, while furthermore the connection arm is slidable relative to the feeler arm and optionally connected therewith and the feeler and blade holder are positioned outside the quadrangular linkage.
Claims13
A beet topping device transportable over the ground comprising:
- (a) a frame (20) having a leading side and a trailing side;
- (b) a feeler arm (3) slidably mounted to said frame for vertically-extensive movement;
- (c) a feeler mounted to said feeler arm for movement therewith;
- (d) a plurality of rods (12, 32), said rods being pivotally connected to one another, one of said rods being pivotally connected to said frame at a coupling point for movement about a horizontal axis, an other one of said rods being connected to said feeler arm so that said rods, feeler arm and frame cooperatively constitute a deformable polygonal linkage;
- (e) a connection arm (10) slidably connected to said feeler arm, said connection arm also being linked to said other one of said rods so that upon upward displacement of said feeler arm said connecting arm will be displaced upwardly to a lesser extent than said feeler arm;
- and
- (f) a topping blade disposed below said feeler, said blade having a cutting edge directed toward the leading side of said frame, said blade being attached to said connection arm for movement therewith, whereby the vertical distance between said blade and said feeler will increase upon upward displacement of said feeler.
