Inlay system at Häckslem

The invention relates to a single stone at Häckslem with pulling means, e.g. rollers and / or chain hoists for inevitable insertion of the cut material, if necessary with adjustable feed through the chopping mouthpiece to the Knives, whereby the drive means for clearing blockages can be switched to forward and reverse rotation ..

With the insertion systems of this type, the drive takes place at least via a claw clutch. This is transmitted when the feed rollers, the pre-press drum and the conveyor belt engage, a forward or reverse gear. The smear position of the dog clutch corresponds to the idling of the machine, the forward gear to the working gear. If the reading device is blocked, reverse gear is used to remove the strand parts from the feed device the machine.

~ in the setting of the feed and thus the chopping ^{- i ::} n ~ e can already provide for different stages. Ken achieves different slopes by exchanging gears or sprockets with different numbers of teeth.

Thus, it is not possible to switch-A during operation at different texture of the cut f-stage Hege averaging the average length is not EÖglich.

The object of the invention is therefore to provide a Einlegsysteni with better acceleration and deceleration ability to create a stepless adjustment of the feed length and thus the chop length allowed.

The invention solves this problem in that at least one reversible device is only used to drive the pull-in means hydrostatic riotor is provided.

You already have a threshing drum and reels. Threshing machines hydraulically driven, but only with one direction of rotation.

The idea here was to save Va ₁ complex, continuously variable mechanical gears. According to the invention, it is sufficient if only the intake system of a forage harvester has a hydrostatic drive, which has two advantages. On the one hand, blockages can be cleared by quickly reversing and, on the other hand, any cutting length can be set through infinitely variable adjustment. In relation to these advantages, the hydrostatic drive according to the invention is hardly more complex than any other transmission solution, especially since mechanical transmissions are subject to greater wear and tear.

In an embodiment of the invention, the hydrostatic motor can be steplessly regulated in a simple manner by a throttle valve provided in the suction line of the pump.

The drive is zi-jeckmäBigerrieise with a ratio of the Kesser drive shafts branched off. Through this conception, the losing., at full speed tier Ilessertrosnel succeed. So that your straight cei blockages ... keep up., stays.

.S

The invention provides in a very advantageous manner mobile machines, the wheel axle as an oil container to train.

The oil becomes zv / angular by arranging the suction line at one end and the return line at the other end of the Radachsbehälters in the circuit passed through the same .

In this way, the cooling of the hydraulic mantle is at the same time with favorable use of space for the Liquid container reached.

According to the invention, provision is also made for the intake flow to scan for metallic foreign bodies by an electromagnetic scanning system and a controlled by it Magnetste1! Valve and one not shown Bypass line in the pressure line feeds the FPoissig flow into the Return oil reservoir.

This can stop the pulling system abruptly and damage it and fractures of the Hessians are avoided.

In the drawing, the invention is based on two aspects, Guide elements explained and described in more detail:
