Title: Corn chopping device

The invention relates to a chopping machine for the better isolation of the maize harvest according to the preamble of claim 1.

In trimmer shredders, it is known, for example, from French patent specification 20, 791, to use finely grinding the supplied corn cobs or corn kernels with the chopping blades and beating strips provided with the chopping blades. The striking edges are formed by square bars, which are arranged next to each other on the leading end of the striking edges connected to the knives, seen in the direction of rotation of the knives. When chopping, the pieces of corncob cut by the knives or the corn kernels are thrown against the striking edges and thus further finely ground.

The disadvantage in these embodiments is that the pieces of corncob or corn kernels come into contact with a striking edge at most once after cutting through the chopping knives. As a result, however, the degree of refinement of the maize necessary for proper ensiliation cannot be achieved. For quality shredding, a friction bottom co-operating with the circumferential chopping drum or a recutting sieve (Recutter) must be used. However, this is cumbersome and expensive.

The invention provides a structurally simple embodiment, which has a good chopping quality. that is to say corn, provides a degree of fineness necessary for good ensilage, without the use of extra expensive crushing agents such as a rubbing bottom, a trimming screen or the like. According to the invention, this is obtained by a measure described in claim 1.

In the embodiment according to this proposal, the material to be chopped, after cutting through the chopping knives, is largely radially outwardly directed along the toothed end of the impact bars by centrifugal force and thus comes into contact with those impact edges several times.

This achieves a refinement of the pieces of corncob as well as of the corn kernels, which is a precondition for a subsequent good ensilage of the corn.

Further details of the invention are explained with reference to the drawing. It shows: 8103435 - 2 -

Pig. 1 is a schematic side view of a disc chopping device; and

Fig. 2 a beating strip according to the invention.

In Fig. 1 a chopping disc is shown by 1, which is provided in the housing 2 with side walls. 3 of a chopper is driven, driven 5 and is occupied with knives b. The circumferential knives b stroke a counter-knife 5 attached to the housing 2, where they chop up the maize which has been pushed through the counter-rollers 6.7 by means of this counter-knife.

A beating strip 9 is clamped between support 8 on the disc t and the knife b. Seen in the direction of rotation of the knives 10 ’b, it has a tooth-shaped leading edge 10 which is tooth-shaped and under one. sharp angle α ten. bent to the bottom of the blade.

The beating bars 9 are approximately the same length as the blades b.

Claims (2)

1. A maize chopper with a chopper, the blades of which cooperate with a counter-knife attached to the tube when turning and the maize kernels with a plurality of flailing edges for grinding the maize kernels supplied are connected in such a way that the flapping edges below the blades, in the circulation direction / are slightly offset from the cutting edges, characterized in that when used with a disc wheel chopper, the striking strips (9) consist of pieces of flat iron lying parallel to the blades (k) or sheet strips, which are attached to them in viewed from the direction of rotation of the blades (k), 10 leading edges (10) serrated and clamped between the blade supports (8) and the blades (k). Chopping device according to claim 1, characterized in that the impact strips (9) are formed from pieces of flat iron or sheet metal strips of small thickness, and at their range leading in the direction of circulation, under a sharp book (a) relative to the underside bent off the blade. 8105435
