Problems solved by technology

A disadvantage of this construction is that, due to the desired deep engagement of the wedge discs, the axial spacing between the rollers is smaller than with conventional rollers, so that this construction requires at least one additional housing

Embodiment Construction

[0033] figure 1 An agricultural harvester in the form of a self-propelled field grinder 30 is shown in a schematic side view. The field shredder 30 is equipped in a manner known per se (and therefore not shown in detail) with front and rear wheels and a (in addition) main drive motor driving them, in order to be moved over a field for harvesting vegetation. The plant population is received into the machine by means of an additional harvesting attachment on the front side, so that it is subsequently in the form of a flow of harvest G (through the through-through, arrow-provided line passing through the field grinder 1 to be briefly shown) are conveyed by different conveying and / or processing units through the machine 1 and processed there, in particular crushed. Here, the rotating pull-in rollers arranged in pairs carry out the pre-compression of the crop G, so that when the crop G passes through the downstream grinding unit 31, it is formed between a rotating grinding drum w...

Abstract

The back crushing device (1) has at least two rollers (10,20) with mutually parallel rotational axes (11,21). Each of the rollers (10, 20) is alternatively provided with a straight portion and an inclined portion in an axial direction (R). The straight portion is provided with a peripheral surface parallel to the rotational axes (11,21), and the inclined portion is provided with a peripheral surface inclined to the rotational axes (11,21). A straight portion (22,12) of one roller (10,20) is arranged to another straight portion (22,12) of the other roller (20,10). The opposite peripheral surfaces of the straight portions form a crushing gap parallel to the rotational axes (11,21). An inclined portion of one roller (10,20) is arranged to another inclined portion of the other roller (20,10). The opposite peripheral surfaces of the inclined portions form a crushing gap inclined to the rotational axes (11,21).

Description

technical field [0001] The invention relates to a post-shredding device for comminuted harvest according to the preamble of claim 1 . Background technique [0002] Agricultural harvesters, such as self-propelled field grinders, are generally equipped with an after-cracker, also known as a regulating device or a corn cracker, when they are used for corn harvesting. Such post-shredding devices serve the purposeful further shredding of harvested material which was previously shredded by one or more processing units, such as in particular a comminution unit. Post-shredding devices in corn harvesting are primarily used for the purpose of preparing the harvest for use as livestock feed or for biogas production. [0003] For this purpose, post-shredding devices known from the prior art generally comprise two rollers arranged parallel to one another, pretensioned relative to one another, and driven in opposite directions, between which the crushed crop is guided through in order to...
