Abstract

A distributing device for chaff choppers for attachment to mowing-threshing machines has a top cover plate, beneath which right and left groups of baffles are arranged next to one another, preferably at right angles to the cover plate. The baffles are pivotably supported around axles at their ends facing the chopper and spaced therefrom, while being rigidly connected by guide bolts penetrating guide slots in the cover plate or in the machine casing. A set bar is associated with each group of baffles. The baffles are connected with each other by the guide bolts which are rotatable in fixed bearings and by two guide rails, and, at their ends facing the chopper, rotatably and displaceably arranged in points on the cover plate. The guide slots of each group extend displaced relative to each other in a transverse direction, substantially parallel to each other and to a line through the axles. The set bars are outwardly inclined to that line and spacing of the guide bolts from the axles decreases from baffle to baffle in correspondence with outward displacement of the guide slots. A set leave is connected jointedly to each set bar, and is articulated in a point spaced from its point of articulation on the set bar on the cover plate. A coupling rod connects the set levers. Thus, the groups of baffles can be adjusted to different extents. The set levers are displaceably connected with the coupling rod and displaceable lengthwise to extents limited by stops.

Dependent claims

Distributing device for a chaff chopper for a mowing-and-threshing machine having a top cover plate or casing, beneath which a right and a left group of baffles are arranged next to one another at an angle, said baffles, at their ends facing the chopper, being spaced from and supported for swinging around axles being rigidly connected with guide bolts to the cover plate or casing, said guide bolts penetrating guide slots in the cover plate or in the casing;

and a set bar associated with each of the two groups of baffles;
whereby the baffles are rotatably connected with the guide bolts in fixed bearings by the set bars and, at their ends facing the chopper, rotatably and displaceably arranged on the cover plate, or casing in the axles;
whereby the guide slots of each group extend in a transverse direction and are substantially parallel with one another and with a line drawn through each of the axles;
whereby the set bars of each group are arranged with an outward inclination relative to the line through each of said axles in a way such that the spacing of the guide bolts from the axles is reduced from one baffle to the next baffle in correspondence with the outward displacement of the guide slots;
whereby a set lever is connected articulatedly to each set bar, each said lever being articulated on said cover plate in each case or casing at a point spaced from the point of articulation thereof on said set bar;
and
whereby a coupling rod connects each said set lever with another set lever of like configuration;
characterized in that the set levers are connected with the coupling rods which are connected to each other and slideable lengthwise, and the lengthwise movement of said coupling rods is limited by inner and outer stops.
