The invention relates to an angular reversible plow, the plow support frame with a tractor over three Coupling handlebar and its plow frame on two in the longitudinal direction of the axis of rotation at a distance from each other lying support points is articulated, the rear support point on a Frame beam is attached, which is connected to the plow support frame and extends in the direction of travel and on which other parts of the plow support frame are rigidly arranged.

In such angled reversible plows, the plow frame protrudes from the support frame or the connection points on the handlebars of the tractor from freely to the rear, so that the side forces occurring during plowing act directly on the coupling between the mutually rotatable parts and this Therefore, strain the coupling. For this reason, the frame and support frame must be very stable, especially if the frame is to carry several plow bodies that are used at the same time.

The invention is based on the object of allowing a light construction of the plow without that the side forces occurring during operation are unfavorable on the mutually rotatable parts of the Affect the frame or support frame.

In the case of an angular reversible plow of the type mentioned at the outset, this is achieved according to the invention by that between an outer end of the cross strut of the plow support frame and the rear ab-

In a further embodiment of the invention, the axes forming the support points are surrounded by springs, which are included between the plow parts and stops attached to the axles, and the Stops are adjustable to adjust the preload of the springs.

The invention is provided with further features in the support point of a strut, which is explained in more detail at the rear 30 following on the basis of the embodiment shown in the drawing of the frame extending in the direction of travel. It shows
balkens attacks. Preferably between the two F i g. 1 is a plan view of the angled reversible plow,

Ends of the cross strut and the rear support. Fig. 2 is a side view of the plow of Fig. 1.

one strut is provided at each point. The plow frame 1 is rotatable on the plow carrier

As a result of the strut according to the invention 35 frame 2 is stored. The support frame 2 includes a the coupling between the mutually rotatable frame beam 3, which consists of an upwardly extending part significantly relieved and is therefore only subject to part 4, a curved part 5 and one itself low wear. The structure of the plow consists of part 6 extending backwards and downwards can easily be held in the desired manner, the frame beam 3 lies in a vertical plane, and several plow bodies 40 and at the free end of its part 4 can be used simultaneously at the same time, so that strut 7 is attached to this.

Plow can be worked faster. With the end of part 6 of the frame beam 3

A vertically arranged plate 8 is connected to the fastening of at least one plow body. In a manner known per se, vertically arranged support points can be located between the far ends of the transverse strut 7. The plates 9 and 10 for the plow 45 are expediently attached. Between the plates 8 supporting frame belonging frame beams upwards and 9 or 8 and 10 a strut 11 or 12 is curved. He is here in the vertical plane, and provided. The two struts 11 and 12 form with its ends are in the vicinity of the support points. the cross strut 7 is a triangle in plan view.

In the case of an angled reversible plow according to the invention, the cross strut 7 has bolts 13 at its ends

in the known manner the plow frame in loading 50 and 14, which engage in corresponding recesses of the train on the plow support frame in a link 100 or 101 to the axis of rotation, which can deflect resiliently to the parallel direction, are tractors.

The plow frame 1 contains two support beams 16 and 17, which have two parts 18, 19 and 20, 21 which are each at an angle to one another. The parts 18 and 20 are connected to one another at their front ends. The rear parts 19, 21 extend to one another in plan view, so that their free ends are adjacent. The parts 19 and 20 are connected to one another via the one-piece beams 22, 23. This beam carries a bearing 24 in which an axle 15 attached to the plow support frame 2 is mounted.

At the connection point of the parts 18 and 20 of the plow frame, an axle 25 is attached, which is mounted in a bearing 26 provided in the cross strut 7. The center line of this bearing and the center line of the axis 15 are in alignment and on the longitudinal axis of the plow, so that the plow frame 1 can be rotated with respect to the plow support frame 2 about an axis extending in the direction of travel of the plow.

The axes 15 and 25 are surrounded by springs 27 and 28, respectively. The spring 28 lies between the bearing 26 and a nut 29 which sits on the thread of the axle 25. In the same way, the spring 27 is between the bearing 24 and the nut 30 supported.

Plow bodies are secured 31.32 or 33.34 to the beam portions 19 and 21 of the plow frame. To fasten the plow body, a two-part clamp 35, 36 is provided, which is clamped with bolts 37 on the corresponding beam part. These clamps are secured against rotation by rails 38 attached to the bar, so that they can be displaced on the bar, but not rotated. The bolts 37 are guided through holes 39 in the rail 38, and two rows of holes are provided so that the distance between the plow bodies can be changed.

The plow is coupled to the tractor via the lower links 100, 101 and the upper link 102 of a tractor lifting device. The upper link 102 is fastened to the bell crank 59 with a bolt 61.

In the position of the plow shown in the drawing, the plow bodies 31 and 32 engage in the Soil while the plow bodies 33 and 34 are out of order. The plow frame 1 can relate to move on the support frame 2 in the longitudinal direction against the force of the springs 27 and 28, respectively. These Resilient mobility in the direction of travel is made possible by the maximum possible compression of the springs limited, so the spring coils are directly adjacent to one another. The preload of the springs 27 and 28 can be changed by adjusting the nuts 30 and 29, respectively.

The plow frame articulated at the two support points formed by the axes 15 and 25 is braced against the cross strut 7 of the support frame 2 in such a way that the struts 11 and 12 absorb the side forces acting on the plow body and therefore additionally support the plow frame so that the against each other moving coupling parts between the plow frame and the support frame are relieved. The stiffening achieved with the struts 11, 12 prevents undesired deformations of the frame.
