DE202008011484U1 - Conveyor roller of a loader for agricultural stalk - Google Patents

Abstract

conveyor roller a loading device for agricultural stalks, that between an upstream collecting drum and a downstream pressing device is arranged, whose length is about the same same working widths of collecting drum and pressing device extends and whose axis is parallel to the axes of the collecting drum and the pressing device runs, characterized that the ends of the conveyor roller (2) as truncated cones (4 and 5) are formed.

Description

The The invention relates to a conveyor roller on a loading device for agricultural stalks according to the generic term of claim 1.

At the loading devices of harvesting vehicles, such as loader wagons and balers, are conveyor rollers, which in support of the transfer of the Halmgutes generally folded into fodder, which taken from the receiving drum from the ground and to a downstream Press device is forwarded, known.

In the utility model DE 20 2007 004 530 the conveyor roller of a prior art type of loading device is described and illustrated, which has over its entire length a cylindrical roller body which is equipped with spirals.

at this execution is the transfer of the of Picking drum recorded Halmgutes to the conveyor roller and on to the pressing device, on the outside Ends of the feed roller can still be optimized, since that in these Outdoor areas to be promoted towards the center, here loosely resting stalks are not grabbed enough by the spirals becomes.

Of the The above defect can according to the invention by Changes at the outer ends of the Conveyor roller to be fixed.

below The invention will be described with reference to an embodiment and shown in the drawings:

1 shows the arrangement of a conveyor roller within the loading device.

2 shows a section A-B through the loading device. The side not shown is symmetrical to the central axis.

3 shows the separate representation of the feed roller.

Inside the loader ( 1 ) of a loading wagon is the conveyor roller ( 2 ) between the recording drum ( 11 ) and the pressing device ( 13 ) arranged.

From the spring tines ( 12 ) of the receiving drum ( 11 ), the stalks generally lying in forage on the ground is taken up and the downstream conveyor drum ( 2 ), which takes over the feed and into the pressing channel ( 14 ) one, with a press roll ( 15 ) equipped pressing device ( 13 ) for forwarding in a downstream loading space ( 17 ) passes.

The conveyor roller ( 2 ), consisting essentially of the roller tube ( 3 ) with the truncated cones ( 4 and 5 ) and the spirals ( 6 . 7 . 8th and 9 ), rotates to the upstream recording drum ( 11 ) in the same direction and to the downstream press roll ( 15 in opposite directions.

That of the conveyor roller ( 2 ) to those with press tines ( 16 ) occupied press roll ( 15 ) to be handed straw feed is preferably in the central region of the transfer width, where the fodder swales have their largest clusters, from the press tines on the conveyor roller ( 2 ) and between the spirals ( 6 and 7 ). This pressure causes in the central region of the working width a grippy distribution of the conveyed material from the middle to the outer sides.

On the outer sides, where the ingested feed swath delivers a small, loose amount of stalk material, little pressure builds up on the conveyor roller. The spiraling from outside to inside ( 8th and 9 ) therefore have only a weak axial conveying component, the proportion of further flowing in the radial direction of flow of crop is still relatively high. For this reason, the ends of the conveyor roller ( 2 ) with spirals ( 8th and 9 ) occupied truncated cones ( 4 and 5 ) fitted. Into the recessed spaces within the turns of the spirals ( 8th and 9 ), with the outer diameter remaining the same, the stalk material is detected more effectively. The spirals ( 8th and 9 ) are more aggressive. The conveying effect from the outside to the middle is intensified.

The attachment of grooves ( 18 ) or spikes ( 19 ), which are evenly or irregularly spaced on the outer diameter of the spirals ( 8th and 9 ), improve the grip and thus the conveying effect on.

The roughening of the spirals ( 6 and 7 ) by grooves ( 18 ) or spikes ( 19 ) is also possible to influence the axial delivery components.
