Reöhköi · per for a device for lateral raking Foreground crop lying on the ground.

The invention relates to one or more, lifted side by side Ilechkörper for a device for turning to the side of crop lying on the sod with an approximate Transverse to the direction of travel Cuerträger, the or the iiechi £ ör.pe-r positive or non-positive drive by about ver * tikäle Br & Hächsen can be moved in the same direction in Br * ehüng.

A lifting body of the type mentioned at the beginning has already been proposed in which a larger number of radially protruding prongs are arranged in several planes one above the other on the circumference of the raking body. The rake tines engage in the lying crop , push it to the side and transfer it to an adjacent rake body * So that the crop is not carried along by the tines *, neighboring tines interlock in a camarden manner * whereby -the next one, © Zinkenkamtn, strips off the crop from the previous one and transported further.

BAD OBIGSNAL

This well-known version has the "Näöiifce-ii" saw at the the tines, which are spaced one on top of the other, penetrate the 'Eritte' well the hacking bodies push the crop first in front of you and then to the side, with the crop still in contact with the "bath fet .." With such an intensive processing of the crop there is There is a risk, especially when it comes to hay, that valuable components of the hay are lost through crumbling. Even the cramped one Interlocking of the prongs of neighboring Rehkörpe "increased" the danger of a destructive effect on the crop »;

Another disadvantage of this design is * that; the Rake body is attached to the bottom of a shaft, the eleventh has a relatively small diameter »So with this version the transverse flow of the raised material on one side of the river is guaranteed * it is necessary about half the height and on the top of the shaft Have the task of transporting the goods from one reef body to another. It has been found, however, that these zinc with Rehmer exert a blow-up effect on the harvested crop, as a result of which you see the loss of breadcrumbs increase to a very great extent. Also: stay on this Driving tines often hang the goods * so that the driver is forced is to turn off the machine and remove the tines from = the Good to get rid of.

The invention is therefore based on the object. To train the rake body as follows:,. that he can harvest the crop in a particularly gentle manner

"Way-picks up from the ground and does it at optimal delivery rate without Leaf and crumbling losses and without the rake body for winding leans transported to the side.

According to the invention, this is achieved in that the rake body is designed as a conveyor drum with a closed outer surface is, as well as a plurality of approximately radially or tangentially protruding prongs are arranged on the underside of the conveyor drum and the The diameter of the conveyor drum is smaller than the rotary acid diameter the prongs.

During work, the tine ends lying on one level grip under the crop lying on the stubble of the field attach it and bring it into the range of action of the conveyor drum that has it; transported to the side.

In another embodiment of the invention, there is the conveyor drum of several approximately vertically arranged rods which are fastened between an annular upper and lower part, wherein are located on the underside of the cage-shaped conveyor drum radially or tangentially protruding prongs and the diameter of the conveyor drum is smaller than the rotation diameter of the. Prongs.

A special feature of the invention is that the Prongs are formed from rods which are curved opposite to the direction of rotation of the rake body.

In another embodiment of the invention, the prongs are made of flexible material.

■ Another feature of the invention is the closed or cage-shaped conveyor drum either cylindrical, conical or polygonal.

It is particularly advantageous to arrange a plurality of conveyor elements running approximately vertically or helically on the conveyor drum.

A special feature of the invention is that the prongs and the rods of the cage-shaped conveyor drum consist of one piece and the rods pass through holes in the lower part of the conveyor drum so that they can move and are fixed in the upper part so that they cannot rotate *

According to a further feature of the invention, the prongs at the lower end of the conveyor drum form an angle of approximately 35o to 8o ^G with its axis of rotation, while the ends of the prongs lie in a plane perpendicular to the axis of rotation of the conveyor drum.

A particular advantage is that the closed or cage-shaped conveyor drum has a frustoconical annular surface on its underside which partially covers the prongs.

According to a further feature of the invention, the conveyor drum is surrounded by a stationary cover plate on its side facing the Quafcäger.

The drive of the rake body, not shown, is provided by the power take-off shaft of the tractor carrying or pulling the device. Of the Rake body consists of a cylindrical conveyor drum 2 with a closed jacket surface 3 ·. At the bottom of the conveyor drum 2 tines 4 are arranged, which are opposite to the direction of rotation of the rake body ^ 2.4 · curved and approximately radially from the conveyor drum stick out. The jacket surface 3 of the conveyor drum 2 has approximately vertically extending conveyor elements 5, which are evenly on Scope of the conveyor drum 2 are distributed.

Below the conveyor drum 2 and the prongs 4 is a support plate 6 or a support roller that is freely rotatable with respect to the conveyor drum 6 (Fig.7) arranged over which the rake body on the ground supports.

All the rake bodies mounted in the cross member 1 are in the same direction driven. Since the rotation diameter of the prongs 4 is larger than the diameter of the conveyor drum 2, grip at work first the tines 4 under the crop lying on the ground and gently feed it to the conveyor drum 2. The conveyor drum 2 is transported the crop to the side and gives it to the neighboring rake body continue until it is deposited in a swath at the discharge end of the device. Through the vertical conveying organs 5, the conveying effect the conveyor drum increased.

In another embodiment (Pig. 2), conveying elements are arranged in a helical manner on the lateral surface J of the conveying drum 2. In addition to the conveying effect to the side, the conveying elements 5 'also exert an upward conveying effect and distribute the crop evenly on the lateral surface J>. '. -

In Fig. 3, the conveyor drum 2 is conical. The rejuvenation upwards also causes the crop to be lifted. The conveyor drum. 2 is either with approximately vertical conveyor elements 5 or provided helical conveying organs.

In another embodiment of the invention (FIG. K) , approximately vertical rods J, which are fastened between an upper part 8 and a lower part 9, form a cage-shaped conveyor drum 2 * arranged opposite to the direction of rotation of the rake body curved prongs.

In a particularly advantageous embodiment of the conveyor drum 2 ¹ (FIG. 5), a rod 7 and a prong 4 are each made from one piece. Here, the zinc rod J, K is non-rotatably attached to the upper part 8 of the conveyor drum 2 * while it is guided in the lower part 9 by holes whose diameter is greater than the diameter of the zinc rod 7 * K .Dadurch the zinc rod "J ₉ forms K during the Work off a torsion spring, which significantly reduces the risk of tine breakage when hitting a solid object, for example a boundary stone,

promotes. A similar effect is achieved when, as shown in Fig.

shown, the prongs 4 on the underside of the conveyor drum 2 with the axis of rotation of the conveyor drum form an angle oC of about 3o - 80 ° and the ends 4 'of the prongs 4 are in a plane perpendicular to the axis of rotation of the conveyor drum.

Finally, FIG. 8 shows an embodiment of the invention in which a cover plate 11 is attached to the cross member 1 that covers the upper part of the conveyor drum 2. This prevents blockages and underneath the cross member 1 comes to wrap the crop.
