The invention relates to the design of the conveyor device for an agricultural self-loading wagon, picked up with the stalk or leaf-like crop lying on the ground and the hold of the carriage is fed.

In these wagons, said crop is first picked up from the ground by a pick-up device, preferably by a rotating pick-up roller, and fed to the lower end of a conveyor channel Push the car. With these known devices, however, with very short-stemmed or leaf-like crops, especially when they lie flat on the ground, difficulties can arise in transferring them from the pick-up device to the conveyor device, as the crop rolls back from the pick-up device and thus not from the tines of the conveyor device is detected.

To remedy this deficiency, so-called baffle plates are often used, which are about can be attached above the receiving drum in the conveyor channel. The disadvantage here is that the Baffles are inherently rigid and are also rigidly attached so that they can accommodate the most diverse, prevailing conditions with regard to the amount and type of crop and uneven ground and the like cannot adapt. They thus work in particular with larger quantities of harvested material annoying and must then be removed again. However, this particular cultivation and dismantling is very Labor and time consuming and therefore very disadvantageous. There is also the risk that loose parts of the crop will get through Build-up on the back of the baffle plates can lead to blockages.

Furthermore, it is already known, in front of the conveying channel, vertically movable from a semicircular shape To arrange pipes existing guide bracket, the rear free ends in the conveying direction in the The receiving area of the conveying channel protrude. However, the disadvantage of this device is the front the holding device deeply guided arch of the guide bracket, as this is during the recording a larger swath has a disruptive effect by pushing open the swath. Like the one mentioned earlier The baffle plate is thus either this guide device, depending on the amount of crop available to add or remove.

This is followed by the invention, the object of which is to provide a device through which a good and safe pick-up and further conveyance loading device for self-loading wagons

also smaller amounts of short-stemmed and leaf-like and a trouble-free uptake and further conveyance even large amounts of long-stemmed crop is guaranteed, and also a subsequent one Installation in almost all types of loading wagons, preferably with trailing pick-up devices enables. This object is achieved according to the invention by a device which from resilient guide brackets, which are individually attached to the front part with their upper front end the guide plates representing the front wall of the conveyor channel or the like, through which in In a known manner, the prongs of the conveyor device engage in the conveyor channel from above, fastened are in such a way that they are at least predominantly only in the vertical plane can evade upwards and at least from the prongs of the conveyor be penetrated on part of their path in the conveyor channel. This will make the crop inevitably pressed against the receiving device and thereby its rolling back or slipping back prevented, so that it safely arrives in that area of the conveyor channel in which the prongs the conveyor are fully effective.

Pushing on even a very thick swath is practically impossible here, since it comes with the resilient bracket only comes into contact when it has already been captured by the receiving device and is raised.

There are already resilient retainers in the conveyor channels of self-loading wagons or other conveying devices known. The purpose of this known retainer, which is preferably made of triangular sheets exist, it is to prevent the crop from slipping back in the conveyor channel. On the handover of the

However, crop from the receiving device to the conveying device have these retainers no influence.

According to a further feature of the invention, the guide brackets are leaf springs that are in the already Said manner od on the front part of the guide plates. Like. Are attached. Instead of These leaf springs can of course also be used in rigid guide brackets, which are shown in the aforementioned way are movably mounted in the vertical plane and counter to the action of springs can move up and back.

The big and therefore decisive advantage of this new guide bracket is that they are in In contrast to the previously known devices of a similar type, they can always remain on the loading wagon, absolutely regardless of which crop is to be loaded, as they adapt well to all harvesting conditions. They are also much cheaper than the previously known devices of a similar type, insensitive against lateral loads and also prevent the crop from sliding back out of the Conveyor channel. After all, they can often be done without special expenses retrospectively for existing loading wagons or other pick-up devices attach.

The invention is illustrated in one embodiment and described below.

The figure shows in a completely schematic representation in side view the front part of a Loading wagons omitting all parts not necessary to understand the invention. So are also the drive means for the receiving device and for the conveying device, as known per se, not shown.

1 with the support frame of the self-loading truck is referred to, which by means of a drawbar 2 to a Tractor can be attached. By a pick-up device 3, which is both a rotating pick-up roller as well as an endless revolving belt equipped with tines or the like. The crop will be picked up from the ground and fed to the conveying channel 4. The conveyor channel consists of a well-known Way from side walls, from one or more rear sheets 5 and a front Wall, which preferably consists of several juxtaposed guide plates 6, between through which the prongs 7 of the conveying device 8 engage in the conveying channel 4. The prongs 7 can either be rigid or movable and steered by means known per se be arranged on the conveyor 8 that its free end is more or less kidney-shaped Describes the path, with the prongs in the lower region of the conveying channel approximately perpendicular to the conveying direction of the crop engage in the conveying channel and out in the upper area of the conveying channel pulled out of the feed channel.

According to the invention now protrude into the lower front part of the conveyor channel 4 curved resilient Guide bracket 9 with their rear ends in the conveying direction. According to the illustrated embodiment these brackets are self-resilient, for example leaf springs with their upper end firmly attached to the front part of the channel wall 6, are advantageously screwed. Your rear The end protrudes into the vicinity of the receiving device 3 into the conveying channel. Instead of leaf springs can of course also springs with a different, for example a circular cross-section be used.

According to a further feature of the invention, at least the rear ends of the resilient guide bracket are 9 curved, with its free end facing the conveyor channel 4. The crop will printed by the resilient bracket 9 against the receiving device 3, so that a rolling back or Slipping back of the crop is prevented. Even short, leaf-like crops are therefore flawless and securely gripped by the prongs 7 and fed through the conveyor channel 4 to the loading space 10, the floor of which is provided with a drivable scraper floor 11 in a manner known per se. As a result the backward inclined position of the resilient bracket 9 also interfere with the recording not thick swaths, so that they can remain on the wagon during loading work of any kind, whereby their position need not be changed.

Another feature of the invention is that the resilient bracket seen in the side view be arranged both in a row behind one another and offset from one another up and down can. This means that it is largely possible to adapt to the various recording conditions.

According to a further feature of the invention, the bracket can both be a self-contained assembly form, which is attached as such, as well as attached as individual elements.
