Description

Agricultural transport trailer with rear unloading

The invention relates to an agricultural Transport trailer for unloading to the rear, with a truck platform, the unloading edge of which can be raised to a height of more than 2000 mm before unloading is. It refers to both semi-trailer and two-axle trailers which are used to transport pourable material, such. B. Root crops, manure, loose mineral fertilizers, gravel, etc. can be used.

With the usual agricultural transport trailers, which by tilting backwards or through If a scraper floor is unloaded, the delivery height of the platform floor is approximately the same as the chassis frame, d. H. between 800 and 1200 mm above the ground.

In many cases, however, a lower delivery level is desirable, e.g. B. when the cargo is loaded into another car or when it is to be unloaded onto a stack or a rental. The desired delivery height is then 2000 to 2500 mm. For this purpose, so-called high tippers have been proposed, in which the tipping axle located at the end of the vehicle is raised before the loading bed is tipped, e.g. by means of an intermediate _{frame e} through

two scissor rods are connected to the chassis,

All known Hoehklpper have the great disadvantage of inability to stand during the unloading process: The center of gravity of the flatbed must be brought to a height that is considerably higher than the delivery height. There is then a risk of tipping over sideways on uneven or softened ground.

Due to the more versatile applicability of such high tippers, the demand was made «that certain goods, z. B. potatoes, must be moved gently. In addition, there was a need to dose the amount unloaded and to regulate the dosage with simple means.

The object of the invention is to provide a * To create traaaport trailers with a high delivery height, the 1 Stable even when unloading on uneven or softened ground that does not hold the transported goods squeezes and presses and allows precise dosing of the dumped quantity.

The object is achieved according to the invention in that the Has the truck bed at its front edge pivot bearing with which it is mounted on the chassis that it in its rear area is connected to the chassis by one or two hydraulic working cylinders, and that the platform floor is equipped in a manner known per se with a scraper floor which can be moved forwards and backwards is, which has a clearing blade, which is in the loading position: on the front platform wall.

In addition, the construction according to the invention offers due to their scraper floor conception towards djn known dump trucks have the advantage * that a manure spreader can be attached instead of the rear flap »so that the trailer can also be used as a manure spreader

An exemplary embodiment of the invention is shown in the drawing. It shows a single-axle trolley in the unloading position.

On both sides of the exhaust cross member k , a hydraulic working cylinder 6 is articulated in bearing brackets 5 'the piston rod 7 of which is mounted from the outside on the side wall of the truck platform 3 in its rear region corresponding to the exhaust cross member of the frame.

The truck bed 3 has a scraper floor 8 in the area of the wagon floor is covered with conveyor strips 9 and to which a clearing blade 10 is attached » which rests in the loading position on the front platform wall.
