The invention relates to a deflection device for the pull rope of a hand scraper, e.g. B. Dung sledge, consisting of a column that can be inserted into the ground with an attached roller for Corner guide of the pull rope, which has a conical approach for the automatic dropping of the pull rope the deflection is provided.

Devices for removing manure from stables are general in the most varied of designs known. In one of these known devices, the same has a rope pulled Dung sledge, which runs through the manure channel and over the rope that can be wound up by a winch is pulled to the dung site. In the aforementioned embodiment, however, there is only a straight-line movement of the manure sledge in the direction of the winch. From this predetermined trajectory you can only minor deviations caused by pushing or pushing the side of the manure sledge Achieve person. A straight direction of movement of the manure sledge has proven itself in practice but proved disadvantageous. Due to the straight direction of movement, the use of such a Transport device if there are no straight obstacles of a general nature between the filling and emptying locations Allow transport route, questioned.

As a result, a transport device has become known, which consists of a cable winch and a load slide exists, which is moved by the rope that can be wound up by the winch in the loaded state and is retrieved empty by hand. The direction of movement of the loaded cargo slide is via Deflection links, in that the pull rope can be detached from them. So that the pulling rope is out of sequence Deflecting member can take place properly, the cargo slide has a separation of rope and deflecting member controlling element. The element consists of one arranged on the front of the cargo slide Control means which causes the deflection member to be released from the pull rope.

The control means is formed from deflector planks attached to a drawbar of the load slide. These planks consist of panels that are inclined backwards and downwards directly on the drawbar arms are arranged behind the drawbar tip. The drawbar is triangular or curved and articulated on the load slide so that it can pivot upwards and downwards, the pivoting is limited downwards by a stop.

As a deflection element for any large changes in direction of the cargo slide, a support arm is a deflection device for the pull rope

provided, the pivot point is on the outside of the curve and the one at its free end has horizontally and cantilevered rope pulley. In the pulley of the aforementioned deflection link the pull rope guided. When the drawbar of the cargo slide starts running, the control means lift the Fork slightly and thus cause the pull rope to gradually loosen from the roll. Of the The load slide is then pivoted in the changed direction of movement.

Furthermore, a device is known in which the pull rope is similar to that in the embodiment described above is guided over a pulley. This pull rope has a conical shape attached at a distance Approaches. By these approaches it is effected that when the approach enters the Deflection pulley the pull rope is raised by the approach so far that the rope over the upper edge the pulley arrives and is therefore released.

The disadvantage of the aforementioned embodiment is that there is no security against an unintentional Jumping out of the pull rope from the rope channel is given.

The inventor has now set himself the task of being aware of the shortcomings identified the aforementioned area to disclose a deflection device in which an unintentional jumping out of the pull rope in the area of the pulley is not possible. To this end the invention characterized in that the column is laterally a tensioning device under the pressure of a spring has with punch tongue, which presses against the pulley and a jumping out of the front Prevents the conical approach located part of the pull rope from the rope groove of the pulley. The following description serves to explain the subject matter according to the invention. An embodiment the object of the invention is shown in the drawing; it shows

F i g. 1 shows a deflection device for the pull rope of a hand scraper in a front view,

F i g. 2 shows a side view of the deflection device according to FIG. 1,

3 shows a further view according to FIGS. 1 and 2, in which the pull rope is thrown off.

According to FIGS. 1 to 3, the pulley 1 is load-bearing Column designated with 2. The deflection roller 1 is arranged in a frame 1 'on the column 2 stored that the pulley 1 relative to the column 2 supporting it has a small angle of inclination having.

The pull rope 3, which is connected to the manure sled 4, runs over the pulley 1. This The pull rope 3 has a conical extension 3 'at a predetermined distance from the manure sledge 4 on.

The frame 1 'arranged on the column 2 has a clamping device S on the side, the punch tongue of which 6 is pressed by the spring 7 against the pulley 1. The pulley 1 is z. B. in shape a V-belt pulley, the axis 1 "of which is in the aforementioned small angle of inclination.

The conical extension 3 'of the pull rope 3 is made of metal, plastic or similar material manufactured.

The mode of operation of the deflection device is as follows: The sledge 4 loaded with manure is pulled by means of the pull rope 3 through the manure gutter of the stall in question. The pull rope 3 runs while over the pulley 1. The stamp tongue 6 of the tensioning device, which is under the pressure of the spring 7 5 presses against the side edge of the pulley 1, causing it to jump out unintentionally of the Zugseües 3 is prevented.

In order to make it possible that the manure sledge 4 can now change its direction of travel, the conical extension 3 'is arranged at a predetermined distance from the manure sledge 4 on the pull rope 3. This conical extension 3 'has the effect that when it enters the deflection roller 1 it raises the pull rope 3 so far that it passes over the upper edge V ″ of the deflection roller 1 and is thereby thrown off. The pull rope 3 now runs over the further deflection devices. As soon as the extension 3 'of the pulling rope 3 runs back into the deflecting roller 1 of the next device, the pulling rope 3 is again thrown over the upper edge Γ "of the deflecting roll 1.

The advantage of the subject matter of the invention over the known is seen in the fact that Due to the arrangement of the tensioning device, the rope can accidentally jump out of the pulley is not given.
