The invention relates to an unloading device with a tine drum for loosening and distributing preferably unchopped shark and leaf material, which is passed through a scraper floor Od. Like. Unloaded from a farm wagon and fed to a conveyor device, such as a blower or elevator will. The tine drum lies with a horizontal axis above the rear end of the Scraper floor and sweeps over its entire width. Instead of a simple farm wagon, it can Can also be easily unloaded from a loading wagon. However, it can also initially be switched to a special loading device, which itself has a scraper floor, have been brought and now pushed from this scraper floor into a conveyor will.

If the crop is unloaded through a scraper floor, especially if it is not chopped, it remains in an intertwined state that pulls apart and dissolves for the sake of uniformity Allocation to a further conveying device makes necessary. This work is when by Hand done, very difficult with the unloading capacity usually required.

There are already attached to the rear end of the wagon distribution devices known which from two or three drums with rigid ripping prongs arranged one above the other in a common frame exist. These drums are suitable for distributing chopped crops; to also for uncut To be able to use the crop are various proposals for special tine designs been made. However, these devices still tend to wind up the Good. They are complex in design and drive. Your weight is great. The high center of gravity is unfavorable for the vehicle. Due to their rigid attachment, the conveyor tines are subject to wear and tear and exposed to destruction. Furthermore, the starting is very difficult because the rigid, outward The tines that point are firmly surrounded by the goods that were packed close to the drums during loading are. They can only be made free or kept free for start-up by taking special measures will. If they are kept free, valuable cargo space is lost.

It has also already been proposed to use a known flail drum as the unloading device to be used with freely swiveling single flails. But in the required dimensioning such a drum to give the single flail the centrifugal force that gives it the necessary to dissolve the Unloading device with a tine drum

Gives the required rigidity or circumferential force, a relatively high circumferential speed is necessary, through which the material is smashed, which leads to considerable damage to the feed, especially in the case of leaf material leads.

The mentioned shortcomings are remedied according to the invention in that the tine drum several extending across the width of the drum, provided with rigid or spring-mounted ripping prongs and has tine carriers which are arranged at a distance from the drum axis and which are rotatably mounted and are coupled to one another in such a way that all tine carriers are always in the same position relative to the center of the drum take in. In this way, a ripper tine, which is single through an obstacle from its Stretched position would be deflected and folded into a position ineffective for funding by a counter-torque supports, which results from the centrifugal force of all ripping tines.

The peripheral speed can be reduced to less than half the size, from which various essential advantages result:

a) Damage to the goods is almost avoided.

b) The force required to tear the goods loose is reduced.

c) The ripping prongs can be given a point pointing forward, with which a portion of the good is safely torn loose. As a result of the small The speed of the good portion then falls after the downward movement due to its gravity below; with rapidly rotating tines, there is no falling off, but the material would be from a tine pointed to the front on the circular path.

According to the invention, the tine carriers are pen-welded, which are mounted on two loose disks by means of links 12 with the changers and have both drive disks 5 connected,
On the other hand, arms which are connected concentrically by means of links. By such an arrangement 13 is supported, and on one side of each prong it is effected that not only the centrifugal forces but also a sprocket 14 are firmly attached. All three of the rotating sprockets 14 introduced via the drive pulleys are connected to the prongs by a chain 15 so that the ripping prongs 9 share the same position. 15 Take the center of the drum.

In the exemplary embodiment according to FIGS. 1 and 2, the ripping tines 9 are mounted via the links 12 and the tines are mounted on the tine drum in a frame 1, the support arms 11 are erected and by which they are pulled around the crop wagon or loading wagon 2 in tabs 3. They are able to hang up and quickly work free by a bracket (not shown) and a radial position is fixed. Two assumptions are to be made on a supporting shaft 4. A further pivoting forward is wedged drive or fixed disks 5 and two loose 65 are limited by a stop in position 36,

The loose disks 6 in the exemplary embodiment according to FIG. 3 align themselves carry in their bearings 7 three tine carriers 8, the ripping prongs 9 due to their centrifugal force from their ripping prongs made of spring steel 9 rest position 35 with increasing speed and

Now the scraper floor 22 is switched on, whereby the load in the orbit of the tine drum device. Each ripping prong tears off its portion with its forwardly directed tip 37 and promotes them backwards in the direction of the arrow. During the downward movement, this portion falls as a result of it Gravity from the ripper tine downwards.

If a ripper meets resistance, its own centrifugal force would be much too weak to control it to overcome this resistance. As a single prong, it would be in an ineligible position fold back. As a result of the positive coupling of all ripping tines, however, it is through a Supported counter-torque, which results from the centrifugal force of all ripping tines.
