group transferred to a loading bed 250 arranged further backwards. The anchor end 510 of the cylinder 508 is hinged to the loading bed 250 by means of a pivot pin 216. The piston rod end 512 is via a pin 218 pivotally connected to a rearwardly directed actuating arm 220, the front end of which is attached to the angle frame 202 is attached.

The loading bed 250 consists of a platform 254 which is pivotable about transverse pins 256. The pivot pins are received in upwardly and rearwardly directed support members 258 at the rear end of the longitudinal frame members 16. To form a pile of bales on the loading bed 250, the second platform 200 is pivoted upwards in order to deposit a group of bales B on the loading bed, so that the bales B assume the position C indicated in FIG. As soon as the first group of bales is set down on the loading bed, the rear of the bales rest against a sliding frame 300, which is moved further backwards on the loading bed by subsequent groups of bales. The bale groups are guided by right and left guide plates 260 on the cart that are attached to upwardly directed front and rear struts 262 and 26 ² I-. At the rear of the platform 254, a plurality of upwardly facing prongs 296 are attached transversely to one another and limit the rearward movement of the sliding frame.

Shall from the one stored on the cargo bed of the wagon Stacks of individual bales are unloaded, so are the bale groups C from cargo bed 250 onto inclined platform 200 returned * where then a cross conveyor 350 the last The bales of the lowest row of bales are gripped and these bales are discarded to the right. Before that, a bale lifter 352 has the above The bales lying at the bottom of the bale layer are raised (Pig. 1) and moved upwards on the loading area 215. The cross conveyor consists, among other things, of an endless chain 354-j on which two carriers 358 are attached those, one each on the left side of the wagon Detected the end of the lowest bale layer in order to unload it to the right (in the direction of travel). The one from hook 362 existing bale lifter 352 is taken from cross conveyor 350 between an extended position for lifting and pushing the top bales up and a retracted position Controlled under the platform retracted position. Located the platform 200 is in its inclined position for unloading individual bales, so the upper bales can after retracting the bale jack hooks slide down the platform until they hit the top of a cross member 298 butt against the front end of the loading bed 250. The cross member protrudes on both sides over the platform according to Pig. 2 out, in order to additionally guide the bales to be unloaded on their lateral displacement path.

The bale lifter 352 consists of a plurality of hooks 362, which are attached to a pivot shaft 364. The pivot shaft 364 is stored below the loading area of the platform 200. The hooks 362, only one of which is shown, are of the Swivel shaft through openings in the loading area 2L5 of the platform

the
form 200 moves through it, moving the upper bale above the lowest bale layer to be unloaded and up on the platform. The pivoted-back rest position of the hooks 362 is shown in FIG. 1 with solid lines.

The workflow on the bale cart is as follows . yourself: When a group of balls is formed on the second platform 200 and then by pivoting the platform has been placed on the loading bed 250, it arrives the sliding frame 500 to the system and presses this to the rear. The movement of the slide frame is controlled by a cylinder 528 that is associated with the slide frame is connected via a cable 342. One end 342e of the cable is attached to the rear end of the platform 254, the cable over four pulleys 342a, 342b, 342c and 342d is guided. According to Pig. 2 is at the end of the

"Piston rod 528b attached to a fork 528c in the side by side the rollers 342a and 342d are supported. The roller 342b is at the rear end of the platform 254 and the Roller 342c is supported at the front end of the platform. The cylinder 528 is at the front end of the platform 254 on the Attached at location 528a. An intermediate portion of cable 242 between pulleys 342b and 342c is shown at location 342g of FIG 2 on the transverse connecting part 314 of the sliding frame attached. When depositing groups of bales on the loading bed 250, the sliding frame moves to the rear moves, with a control valve 530 (according to FIG. 3) in its normal position, so that hydraulic oil from the

| Anchoring end of the cylinder 528 is displaced via a pressure relief valve 532, which serves as a brake, so that the sliding frame only moves when a new group of bales is placed on the loading bed. Part of the repressed Hydraulic oil flows via line 533 and a check valve 534 into the piston rod end of cylinder 528, during the excess of hydraulic oil in reservoir 514 flows back. Once the cargo bed is completely filled with bales is, the prongs 302 of the Versohiebegeg are on the prongs attached to the rear of the platform 254 on, the rearward-facing profile section 306 on

facing each other inner seldom the prongs 296 rests in order to achieve a lateral stability.

The pile of bales now on the loading bed can be connected to be placed on the floor by the cylinder 535 the loading bed 250 about the axis 256 in a not shown vertical position with respect to the chassis upwards ~ pivots. If the carriage is moved forward with the loading bed 250 in this position, the stack remains on the floor stand. The entire stack can be picked up in the same way, but with the reverse workflow, by using the Car backs up to the stack so that the tines Move 296 and 302 under the stack and support the bales, when the loading bed 250 swings back into the position shown in FIG. 1.

The second platform 200 brought into the working position shown in Fig. 1 with solid lines. This is done by appropriate actuation of the cylinder 508. If the platform 200 is in this position inclined to the traveling frame, the sliding frame moved forward to transfer a group of bales onto platform 200. This forward movement is done by Extending the piston rod 528b from the cylinder 528 so that the central portion of the cable 342 moves forward. Of the Cylinder 528 is controlled by an adjusting lever 546 and various valves 544, 552 and 530. If the lever 546 is in its End position waving backwards according to position 1 in Fig. moved, the slide of valves 544 and 552 also move backwards, so that pressurized hydraulic oil from the Control valve 544, via line 554 and valve 552 into the line 556 flows. As a result, the valve 530 is adjusted from its normal position according to FIG. 3 so that hydraulic oil is then from line 556 through valve 530 into the anchor end of the cylinder 528 flows. By moving the Versahlebestell 300 becomes the foremost group of bales of the

The stack is pushed over a transverse box girder 298 at the front end of the platform 254 and falls onto the second platform 200, where they are shown in FIG Position D.

After dropping a group of bales onto the transfer platform 200 the sliding frame is stopped and a motor 560 for driving the transverse conveyor 350 is switched on. this takes place by moving the lever 546 to an intermediate position (position 2 in Pig. 3), whereby the slide of the valve 552 in its front normal position shown in Fig. 3, returns, while the slide of the valve 544 its rearward Maintains position. Hydraulic oil now flows out of line 544 via valve 552 into line 558 and from there to the rotating hydraulic motor 56O, from where it is over line 562 flows back into reservoir 514. The output shaft 564 of the motor 560 is coupled to a sprocket, not shown, over which the chain of the cross conveyor runs. Due to the rotation of the chain of the cross conveyor, the bale lifter 352 is actuated, with the drivers 358 grasp the bottom layer of bales on the conveyor chain and eject the individual bales from the side of the trolley.

When the bale groups are transferred to the second platform 200 are the hooks 362 of the bale jack in their end position retracted under the top 215 of the platform. The movement of the hooks to the extended end position for grasping and lifting bales takes place as a function of the movement of the transverse conveyor 350 by not shown Coupling and control parts. After the bottom layer of bales has been unloaded from platform 200, the Hook 362 withdrawn so that the next lower bale layer ■ can slide downwards. If the conveyor chain continues to move the hooks of the bale lifter are then extended again to remove the next higher bale layer from the lowest bale take off and disconnect. Are all layers of Bali

unload the group of bales deposited on the platform 200, wird.mittel the sliding frame tipped another group from the loading bed 250.

Control valves 544 and 552 are associated with the adjusting lever 546 to ensure that the sliding frame can only be moved forward when the hooks of the bale jack 552 are in their retracted position. The motor and the cylinder 528 of the sliding frame cannot be acted upon or driven at the same time. The valve 552 directs the hydraulic oil from the line 554 to either the cylinder 528 or the motor 560. When the lever 546 to its intermediate position (position 2 in Pig. 3), so the motor rotates 56o _# When the lever 546 according to hir ^ en adjusted (position 1), the slide of the valve 542 only moves backwards if the hooks 362 assume their retracted position. A pawl 432 holds the slide of the valve 552 in its forward position until it is unlocked by a control cable 434. The front end of the control cable 434 is connected to one side of the pivot shaft for operating the hooks 362. The control cable unlocks the pawl 432 only when the pivot shaft 364 has been rotated counterclockwise according to FIG. 1 to its end position in which the hooks 362 are retracted under the platform. As soon as the pawl is unlocked, the valve slide can move backwards, which stops the cross conveyor.
