plate on which is slightly below the top of the in which the prongs 11 ends at the top in one eye,

Device supported silage block along this which is formed by a number of turns

and by means of which the prong is pivotably suspended on its support axis 10.

During the working stroke of the support frame 9, these prongs 11 are held in place by a stop cam 12 that interacts therewith and is connected to the support frame 9 in an operating position that extends obliquely downwards and in the direction of movement. During the return movement, the prongs 11 assume a somewhat flatter rest position (FIG. 5).

A plurality of support plates 13 are mounted at some distance from one another on each support shaft 10. These support plates 13, which are arranged on each support shaft 10 are connected to one another by a U-shaped connecting plate 14. Also are on everyone Support axis 10 between the eyes of the prongs 11 or A number of spacer sleeves 15 are arranged between the eyes of the prongs 11 'and the support plates 13 (Figs. 5 and 6).

The support plates 13 carry in their entirety a first continuous stop rail 16, which at Working stroke of the support frame 9 against the stop cam 12 'abuts and then in turn a stop for the Forms prongs 11 in the operating position (Fig. 5).

Incidentally, these stop cams 12 are opposite in the direction of the reciprocating movement the support frame 9 adjustable.

In the embodiment shown in the drawing, the prongs 11 can be switched so that they can throw the silage to one side or the other. To this end lies opposite for each stop cam 12 a counter stop cam 12 ', which is used to throw the silage to the other side, always only one of the two Stop cam 12, 12 'is effective and the other stop cam 12', 12 is ineffective (FIG. 5).

The support platforms 13 carry on each support axis 10 In addition, a second stop rail 16 'connecting them all, which after reversing the throwing direction by adjusting the stop cams 12, 12' during the working stroke of the support frame 9 against the counter-stop cam 12 'interacting with it, and then in turn a counter-stop forms for the prongs 11 in their operating position here is always only one of the stop rails 16, 16 'effective and the other stop rail 16' or 16 ineffective.

As especially Fig.5 shows, is between each Stop cam 12 and the associated counter stop cam 12 'a driver 17 is arranged, which when adjusting the stop cam 12, 12' with respect to the support frame 9 for the purpose of reversing the throwing direction with one of the stop rails 16, 16 'in Intervention occurs and this is forcibly pivoted from the effective position to the inoperative position in this way it is prevented that a number of support plates 13 when adjusting the stop cams 12, 12 ' can get stuck, which would result in a blockage.

In the middle of the support frame 9, a central U-profile 18, which is open at the top, runs in the direction of the and forward movement and parallel to two opposite support frame sides 9 ', 9 ". On both sides of this U-profile 18 a number of support axes 10 are attached at right angles to this U-profile 18 and the relevant support frame side 9', 9" F i g. 3 always shows two support axles 10 on both sides of the U-profile 18 in a line.

Even if in Fi g. 3 the prongs 11 on the successive support axles 10 in the direction of the back and forth forward movement of the support frame 9 each lie in one plane, it is also easily possible to arrange these prongs 11 on the support axles in such a way that they are offset against each other on two consecutive supporting axes 10.

Under the U-profile 18 is a carrier 18 'for the stop cams 12, the counter stop cams 12' and the Driver 17 mounted adjustable in the longitudinal direction of the U-profile 18. As Fig. 6 shows, these are Impact cams 12, the counter-stop cams 12 'and the drivers 17 are attached to both sides of the carrier 18', while the stop rails 16, 16 'are attached to each support axis 10. on the support plates 13 on the side of the U-profile 18 on the inner, on the relevant support axis 10

is run past tines 11.

A number (three in the illustrated embodiment) horizontal rods 19 are attached to the distribution device 7, which can be moved up and down, which during the return of the support frame 9 on the one carried along by the prongs 11 during the outward run Lay on the silage and prevent this loose silage from following the return movement of the tines 11 can, d. H. so can be covered again from these.

In the central U-profile 18, a piston rod 20 is attached, which in the direction of the reciprocating Movement of the support frame 9 takes place. This piston rod 20 carries a piston 21 in its center double-acting cylinder 20, the latter with the reciprocating distributor device 7 is connected.

The upright frame part 4 has two parallel, vertically upwardly extending profiles 23 in which rollers 24 are guided, which in stands 25 of the frame of the distributor device 7 which can be moved up and down are supported. This stand 25 wear two arms 26, between which a cross member 27 runs. The arms 26 carry the at their free end double-acting cylinder 22. Under the cross member 27 vertical support straps 28 are attached to soft the underside are rigidly connected to the uprights 25 via an intermediate band and each carry a guide roller 29 which is inserted into one of the support frame side 9 "formed rail engage.

One of the arms 26 of the distributor device 7 which can be moved up and down carries a second cylinder-piston unit 30, which runs horizontally. The piston rod of this unit 30 carries two on one horizontal discs 31 mounted on the vertical axis,

so while the cylinder carries two vertical disks 32 mounted on a horizontal axis A cable 33 (Fig. 7) is attached at one end to the upstanding frame part 4 and runs over the one vertical disk 32, the lowermost horizontal disk 31, then over the other vertical disk 32 and over the top horizontal disk 31 to the cylinder of the second cylinder-piston unit 30, which in turn is connected to the distributor device 7 which can be moved up and down

In Fig. 4 shows the hydraulic circuit for operating the device described above carries a feed line 35 from the tractor 34 via a valve 36 or the like to a switch 37 two switch positions. In one switch position this first switch 37 is the double-acting cylinder 22 connected to the oil circuit by a switch valve 38. As can be seen in FIG. 7, this switching valve 38 is provided with stops 39, soft with the towards

and backward movable support frame 9 are connected.

In the other switch position of this first switch 37, the supply line or the drain line for the blocked oil to or from the double-acting cylinder 32 so that the support frame 9 is blocked and can no longer move back and forth. The pressure oil line then leads from this first switch 37 to a second switch 40 with three switch positions. In the first switch position of this second switch ters 40, the oil supply to the second cylinder-piston unit is opened, whereby the up and down movable distributor device 7 through the cable 33 quickly is guided upwards. In the second switch position of this second switch 40, the first switch 37 connected to a third switch 41, which has three switch positions and through which the tapping spade 6 can be moved up and down. The second Switch 40 also connects the second cylinder-piston unit 30 in its third switch position the third switch 41 with the return line for the hydraulic oil, whereby the movable up and down Distribution device 7 is moved quickly downwards.

The line 42 between the second switch 40 and the second cylinder-piston unit 30 is via a Line 43 is connected to the inlet side of a plunger pump 44. The plunger of this plunger pump 44 is actuated by one of the stops 39 on the support frame 9 which can be moved back and forth and which carries an adjustable stop screw 45. This plunger periodically presses with each reciprocating stroke of the support frame 9 via a spring-loaded valve

46 of the plunger pump 44 some oil into the overflow line

47 between the switching valve 38 and the first switch 37. When the plunger 44 is released again by the stop screw 45, some oil flows out of the second cylinder / piston unit 30 to plunger pump 44 to replace the displaced oil.

In this way it is achieved that the up and down movable distributor device 7, soft as it were on Oil hangs in the second cylinder-piston unit 30, receives an intermittent downward movement through this periodic delivery of small amounts of oil

From the third switch 41 to the tractor 34 leading return line 48, a slide 49 is used

The three switches 37, 40 and 41 are locked against one another in such a way that only one of them can ever come into effect.

Even if the invention has only been explained above with reference to a single exemplary embodiment, so are of course the most varied of modifications within the framework of the respective operating conditions possible as long as this does not affect the idea of the invention.
