description

The invention relates to a pick-up device, in particular for collective trailers, forage harvesters, combine harvesters and like that.

The previously known devices of this type contain a control system for the binder tines in the form of a cam-roller mechanism (e.g. DE-PSs 1 457 967 and 2 124 342). The short-term wear of such mechanisms due to the friction of the rollers on the curves after a short period of operation is accelerated by the fact that there is practically no possibility of protecting the mechanism from the action of mineral and organic dust, as well as pollution by protecting the earth, sand and plant particles. As a result of the wear of the curve or the seizure of the rollers Severe damage occurs to the entire pick-up device. Experience has shown that curve binders are no longer operational, as a result of which machines with such mechanisms require at least two to three major repairs during a period of use, which reduces the practical operability and increases the costs considerably.

The purpose of the invention is to eliminate these drawbacks and to prevent undesirable wear and tear on the drive of the pick-up device.

The pick-up device according to the invention basically has no disadvantages of the known pick-up devices because with her a constructively different than

Galloster, less sensitive to the difficult field work conditions adapted drive applied.

The receiving device according to the invention is characterized by a rotating drive box with a front Dusting-protected control system for the finger bars is provided, the box rotatable on one side on one immovable crank pin, and on the other hand via a truss axis fixed to the box in the bearing of the frame the device and the axle is preferably driven by a chain wheel.

The device is also characterized by the structural solution of the crank system located in the box, which consists of an immovable crank attached to the frame, the first leg of which is an immovable pin, around which the drive box rotates, and the second leg of which is an axis for the means of the in the legs of the Finger bar is set pendulum-like with the finger bar connected crank rods, these bars with their other ends are mounted pendulum-like in the bearings of a disc fixedly connected to the axis of the device. the The crank can also be arranged so as to be adjustable in order to enable the trajectory of the finger ends to be adjusted as desired.

The receiving device according to the invention, provided with a drive box sealed from the outside, is around a Much more wear-resistant than pick-up devices with cam mechanisms.

The invention is explained in more detail using the exemplary embodiment shown in the drawing. Show it:

Fig. 3 shows schematically the paths of the finger ends of the finger bars of the device, based on the cover the device.

The pick-up device according to the invention consists of some finger bars 9 arranged in any number at equal angular intervals around axis 1 of the device is on the one hand firmly attached to the rotating drive box 3, which tightly encloses the crank system, which the individual finger bars 9 drives and brings the spring fingers 14 into the movement shown in FIG. 3 related to the cover 15. The axis 1 is on the other hand rotatably mounted in the bearing 4 of the frame. On the protruding pin 5 of the axle is the drive wheel 13, preferably a chain wheel, is attached. In front of the bearing 4, one of the sins of the finger bars 9 is pendulum-like disc 2, which is held in bearings, is firmly connected to the axle.

The box 3 is rotatable together with the axis 1 in the bearing 6 on the immovable pin fixed in the frame 7 of the crank 8 mounted.

The crank 8 has a pin which is connected to the connecting rods 12, which preferably have arc-like legs is. The connecting rods 12 are connected to the finger bars 9 by means of bolts 11 via pairs of legs 10. The feather fingers 14 of the beams 9 are firmly attached to these beams; its ends describe the axis 1 with a full revolution 3, the fingers 14 disappearing behind the cover 15 on part of their path.

The crank 8 can e.g. be adjustable in relation to the frame. at
