Loading wagons

The invention relates to a self-propelled wagon in which a receiving device on the boat picks up harvested material and leaves and delivers it to a conveyor device which conveys the harvested material through a conveyor channel essentially in an upward direction into a loading space.

In a loading wagon of this type, the crop transported into the loading area is pushed up to the loading wall until it falls backwards and forms a flat heap.

With the scraper floor, this pile of crops can be moved backwards and new crops can be added.

Finally, when the loading process is completed, the front part of the loading space is filled with compressed cargo up to the tensioning cables on the top of the loading space, while a considerable empty space remains in front of the rear wall of the loading space, which can no longer be filled, which means that the pressure in the rear loading area remains low and is overall insufficient.

The invention aims to improve the filling of the loading space with simple means and also to enable retrofitting to loading wagons.

In a loading wagon of the type described above, the problem is solved with the features of the characterizing part of claim 1.

This creates a rigid counter support and guideway in the area behind the front wall of the loading area, which absorbs the pressure of the crop from the conveyor and allows a much greater compaction than with previous arrangements, while at the same time the pressed load can be moved backwards more easily by operating the scraper bed.

The length of the press flap is determined by how far back the pressure is exerted by the conveyor device on the load in order to use this as effectively as possible for the press and to avoid this pressure pressing the load too hard against the cover ropes and then making it difficult to move the pressed load backwards. 15

The subclaims relate to particularly advantageous additions to the invention and, together with claim 1, form part of the description.

Thanks to the removable attachment of spring-loaded supports, the press flap can be removed if necessary or can be retrofitted.

The split, spring-loaded design of the supports enables the flexible attachment of the press flap and the The pressing range can be influenced by adjusting the spring tension.

Furthermore, this makes it possible to use a control switch, with the help of which the transport of the compressed cargo to the rear by means of a scraper floor and its stopping can be carried out automatically, whereby the entire loading space is completely filled with cargo that is essentially compressed to the same degree, thus allowing a much better use of the loading space.

By maintaining an obtuse angle between the front wall of the loading area and the press flap, the transport of the load to the rear is made considerably easier.

In addition, the inclination of the upper part of the front wall towards the rear also has a beneficial effect.

By using profiles and shaped tubes, a very stable construction is achieved, with the profiles running to the rear greatly improving the guidance of the load.

To ensure sufficient pressing effect, it is important to adjust the weight and pre-tension of the compression springs of the supports to the pressing pressure exerted by the conveyor device.

By connecting the press flap with the cover parts leading to the rear, a continuation of the guide to the rear is achieved, adapted to a set filling level.

The invention is then described using the drawing of an embodiment of the invention. 25

which it releases through the conveyor channel 3 in an upward direction along the front wall 6 of a loading space 4 into the latter, which is also formed by two side walls 7, a floor 9 designed as a scraper floor 5 and an openable rear wall 8 and whose upper side 10 consists of cover parts 11 which extend from the front wall 6 to the rear wall 8.

The front wall 6 is provided with an upper part 27, which is arranged at an angle to the rear and on whose upper end 12 several tabs 32 are attached at intervals from one another, which form hinge joints 35 with corresponding tabs 34, which are attached to the front cross member 29 of a pressing flap 14 and with pivot pins 33, to which the pressing flap 14 is attached so that it can be swung up and down.

The press flap 14 consists of a front cross member 29 and a rear cross member 30 and of profiles 28 arranged between them over the width 13 of the front wall 6, aligned from front to back, which are welded on both sides to the cross members 29 and 30.

At the rear end of the press flap 14, supports 17 are arranged on both sides, with which it is hingedly connected to the side walls.

Each support 17 consists of a rod-shaped support part 18 and a bearing part 19, in whose guides 20, 20' the rod-shaped support part 18 is slidably guided.

A compression spring 21 is inserted between the upper guide 20 and an abutment 41 on the rod-shaped support part 18. 35

The rod-shaped support part 18 is bent at the top and is attached as a bolt-bore arrangement 22 to the press flap 14 and the bearing part 19 is attached with a bolt-bore arrangement 23 to a carrier part 37 and secured with pins 24,24'.

The support part 37 is connected to the upper longitudinal support 38 of the side wall 7 in one of several holes 40, 40', 40'' arranged in the longitudinal direction 39 of the loading space 4.

By selecting the corresponding holes 40,40'' or 40,40''', the inclination of the pressure flap 14 can be adjusted backwards, whereby when it is in the basic position, in which it assumes the lowest position under the action of the compression spring 21, it has an obtuse angle 26 of 120 degrees with the front wall 6 of the loading space 4.

At the rear end 15 of the press flap 14, brackets 31 are attached across the width 13 of the rear cross member 30, into which the cover cables 11 are hooked with their front ends 16, while they are fastened at the rear ends to the rear wall 8 of the loading space 4.

During loading, the crop is pushed upwards by the conveyor channel 3 along the front wall 6 until it hits the press flap 14 and is pressed against it until the movement of the press flap 14 upwards beyond a preset position actuates the control switch, which activates a circuit via which the drive of the scraper floor 5 is switched on.

The crop is then moved backwards until the control switch 25 is lowered by the pressing flap 14 in

the home position returns, whereupon the drive of the scraper floor 5 is stopped again.

This process is repeated until the cargo space <. is completely full.
