The invention relates to a rear-mounted device for loading a conveyor with a floor conveyor Od. The like. Provided agricultural vehicle with automatically picked up from the ground Halmoder Leaf crops as well as for unloading the vehicle or spreading its cargo, which from an endless conveyor with tines or the like. The aim of the invention is to be that the conveyor, without having to change its position, both for loading the Wagon with stalks and leaf crops lying on the ground or scattered around, as well as for unloading of the wagon loaded with the goods mentioned or with manure.

It is already known, on the rear of an od with a roller floor endless conveyor device, preferably driven by two deflecting rollers and equipped with prongs to be arranged, which is used both for loading and unloading the wagon. So shows a be ao Known agricultural transport vehicle a rear-mounted loading and unloading device, in essentially consisting of several juxtaposed endless, revolving, studded with prongs Conveyor belts and a gripper roller arranged above. As a result of the leaning towards the hold The location of this device is a loading of the car with loose cargo, but only under simultaneous direct participation of the endless, all-round roller floor is possible, which is with a must be driven relatively high speed, otherwise the conveyor pulls the loaded goods, at least partially, back down from the wagon immediately. The fast speed However, the roller floor is disadvantageous because it results in a completely inadequate compression of the load Good is achieved. This device is switched from loading to unloading or vice versa by pivoting the conveyor in the vertical, parallel to the longitudinal axis of the car Level and is therefore relatively cumbersome and expensive, in particular due to the arrangement or training of the necessary drive for the conveyor.

It is also already known to assign guiding means to rotating conveyor drums and also to endless conveyor belts fitted with tines, which are shaped so that the conveyed material is lifted off the conveyor tines in a certain section of the conveying path. However, these guide means are fixedly arranged on the support frame of the conveying device, so that the once set conveying direction or the device for loading and unloading a

set point in time for the deflection of the conveyed material cannot be changed.

The invention overcomes these disadvantages in that a guide grate is pivotably assigned to the conveyor device is, so that this can be pivoted optionally and as needed so that depending on the Position of the same the prongs of the conveyor either over the entire length of its conveying path or reach through the guide grate only on part of this path. This makes it possible to use the conveyor without having to change their position, depending on the position of the guide grate, both for unloading and can also be used for loading the wagon, including in the latter case the conveyor device in on In a known manner, the conveyed goods by a pickup drum arranged below the same od. The like. is fed. When the car is loaded, the pivoting of the guide grate also results in the great advantage that the load is inevitably stripped from the prongs by the same, with at the same time there is a certain compression of the cargo in the direction of the hold.

Another feature of the invention is that the pivotable guide grate at its upper Another guide plate is assigned to the end, which overhangs the loaded goods over the avoids pivotable guide grate backwards and thus on the conveyor.

The invention is illustrated in an exemplary embodiment and is described in more detail below. The drawing shows a trolley of the type mentioned with the device according to the invention in a schematic representation in the side view.

On the trolley 1, which can be single or multi-axle, is at the rear in a manner known per se an endless, pronged conveyor! arranged, the direction of movement in

is also reversible in a manner known per se. A guide grate 3 is assigned to this conveyor device, which according to the invention can be pivoted in the vertical plane parallel to the longitudinal direction of the car. The guide grate can consist of individual sheet metal strips or rods at their lower end combined into a unit outside of the space swept by the prongs of the conveyor device and are pivotable about a horizontal axis perpendicular to the longitudinal direction of the carriage.

To load the car, the guide grate is brought into the position shown so that the tines of the When it moves downward, the conveyor device 2 only passes through the lower part of the guide grate 3. This is done by a also known per se receiving device 4 of the conveyor! supplied cargo inevitably stripped of the same from the prongs and continued by the Loaded goods fed in from below on the side of the guide grate facing away from the conveying device into the Load space pushed in and pressed within certain limits. The guide grate 3 is on his A further guide means 5, for example a guide plate, assigned to the upper end, the upper edge of which is expedient turned towards the cargo hold too. This avoids having a high Loading of the loading space Cargo via the guide grate 3 is in contact with the conveying device 2 comes and is thrown back to the ground.

The compression of the cargo in the hold can be increased in a manner known per se by that at the beginning of the loading process, the rolling floor, not shown, of the trolley is not yet is driven, but only later, when a certain compression of the load has already taken place, whereby at the same time an even filling of the cargo space is achieved.

If, on the other hand, cargo located in the loading space of the transport vehicle is to be unloaded, the Guide grate 3 is pivoted into the position shown in dashed lines, so that the prongs of the conveyor 2 reach through the guide grate along the entire length of its upward movement. By doing this towards The load is pushed against the conveyor 2 on the conveyor belt moving floor and then conveyed up or down depending on the direction of movement of the same.

When the cargo is conveyed downwards, a spreading roller can be used instead of the receiving device 4 be arranged, which distributes the cargo, for example stable manure, more finely and spreads out laterally.

If the load is only to be unloaded or possibly reloaded to another wagon, in In a manner known per se, the conveying device including the guide grate 3 is pivoted backwards and be brought into a horizontal position, for example.

As in contrast to previously known similar conveying devices for loading and unloading the car each must be brought into a different position, this in the subject matter of the invention their location retains or can retain, the receiving device 4 is arranged below the conveyor device 2. In order to tilt back at the transfer point between the receiving device and the conveyor device of the load picked up from the floor by the pick-up device is to be prevented according to a further feature of the invention of

ίο named transfer point another control means 6 assigned. To achieve an always optimal distance between the receiving device and the Conducting means in changing conditions of use can be made by known construction elements Guide means can be arranged displaceably or displaceably with respect to the receiving device.
