Abstract

The invention relates to a drive system for the Zufuehrorgane a Feldhaeckslers, which are formed from upper and lower rollers, wherein at least one höhenveraenderlich is arranged and has an opposite direction of rotation relative to the stationary mounted in the frame of Haeckselaggregates rolls. The aim is to provide a common drive capability for two stationary rollers and a parallel to the axis displaceable, drivable in the reverse direction of the feed roller with minimum width. This is achieved by assigning the main drive to one side of the lower feed roller (7) and by applying on the opposite side on the shaft (9) of the feed roller (7) a spur gear (10) which is mounted in a journal (13). fixed drive pinion (11) engages. The bearing pin (13) forms the lower pivot point of a double-ring gear (17, 25) which is arranged between the bearing pin (13), axis (16) and press roller (23) and whose inflection point in the axis (15), which is another intermediate (20) bears, which once with the drive pinion (11) and on the other with a spur gear (21) on the axially parallel displaceable press roller (23) is in operative connection.

Description

Title of the invention

Drive system for the feeders of a forage harvester

,i ,     ..

Field of application of the invention. ·

The invention relates to the drive system for the Zuführorgane a forage harvester, which are formed from roller systems and cause the inevitable collection and promotion of the crop to the cutting member. In this case, the roller system is formed by «lower and upper rollers, wherein

, the upper rollers for the purpose of adaptation to different Gutstrangdicken in the intake duct are lifted and must be driven in the reverse direction to the lower rollers. , '

Characteristic of the known technical solutions

For the design of the drive of the intake organs to forage harvesters have been the most diverse solutions

. ' proposed. For example, in the brochure "Self-propelled forage harvester SFH 3008/4010" by Deutz / Fahr, the drive mechanism of the intake system is shown, in which the upper and lower intake rollers are moved by cardan shafts from a gearbox located to the side of the chopping unit. By the drive shafts becomes at the same time

  Transmission of the rotational movement of the different positions of the upper intake organs met. ·

Such a drive design has the disadvantage that the aggregate complex intake organ chaff device drive system requires a very large space, which is transverse

the direction of travel over the entire width of the machine extends · In ^- another known embodiment of a forage harvester is also laterally adjacent to the chopping assembly, a transmission arranged takes place from which the drive of the feed rollers via chain drives, and thus the Aushebbarkeit the upper roll can be met. This height-adjustable roller kanrv only one movement.um on: perform a fixed pivot point, which is also the starting point for the drive of this roller'is. , :

This solution has the Hachteile that also here the location of the transmission in addition to the Häekselaggregat a wide · 'space required, the chain drives, especially in Schnellstopvorrichtungeh. Inappropriate ^: are and the accessibility to the arrival. _{: /} Driebs- and structural elements between the Häckselkastenseitenwand'm significantly more difficult. ,

.Desweiteren is a drive solution known aus'der DD-PS 205 597, in which the upper feed rollers, which is associated with a spur gear, ,, from a fixed driving point by a the width of the feed rolls, bridging drive _shaft:, starting driven. The lower rollers, on the other hand, will be.

Object of the invention - "· ν '. ^V:

 The invention has the 'aim to provide a drive system for the feeder of a forage harvester, which transmits the drive from an in the frame of Häckselaggregates immutable fixed roller on an axially parallel displaceable roller, with only a small lateral space requirement is required and still good accessibility to Hackseiaggregat allows.

"Explanation of the essence of the invention

The object of the invention is to design a drive system for the feeder units of a forage harvester. "That a roller of the feeder system fixedly mounted in the frame of the chopper unit can be used in a confined space and without additional chain drives in both a stationary and an axle.

parallel displaceable and in the opposite direction of rotation 'rotating roller can be driven.

Exfindungsgemäß this is achieved in that a lower, "i stationary arranged in the frame of the chopper feed roller on one side driven by a propeller shaft

Angular gear, and on the opposite side ". · A spur gear is mounted, the .mit. With a mounted in the frame of the chopping unit, another positionally stable roller and a double swing gear with respect to its position to the stationary rollers axially parallel displaceable roller,

Also allows such a drive ''system'die free, axially parallel movement and the rotation Rich-35-tung inverting the upper .Einzugswalzen from that in the ^frame: the Häekse aggregates stationary lower feed rollers.
