The invention relates to a device for adjusting the lateral inclination of the plow body Mounted reversible plows with a plow body carrying the plow body and pivotable by lifting the plow body Rotary piece, which at its rotary movement on a concentric to its axis of rotation Bahn entrained notches in the working positions of the plow body by means of a below Angle of a spring standing pawl can be locked and that with two on both sides of its Axis of rotation arranged pin is connected, on which alternately the rotating piece in the one or other direction of rotation pivoting driver engages when lifting the plow body, the it receives a constant stroke through a force-controlled drive gear and before the stroke begins the pawl is disengaged against its spring load.

The term mounted reversible plow in connection with the present invention is a To understand suspension of the plow on the tractor, which in the case of the usual three-point linkage is a Connection of two lower links and one upper link with a coupling on which a pivot pin sits, around the axis of which a rotating piece can be pivoted, which has a plow leg on each of its legs carries with ploughshare. The ploughshare can be replaced by a chisel or heavy hook be the one for loosening or biting a furrow previously made with another plow serves.

In practice, when plowing, it is generally necessary to adjust the inclination of the plow about its longitudinal axis To be taken into account if z. B. the wheels of the tractor on one side in a furrow, d. H. so according to the draft set on the upper handlebar, run deeper than the tractor wheels of the on the other side of the tractor and / or if the terrain is sloping or sloping across the furrow direction is to be edited.

These requirements can be met relatively easily with the reversible plows mentioned, because there only one adjustment of the pivoting movement corresponding to the respective inclination of the rotating piece limiting detents needs to be made and the falling movement of the Rotary piece is ended as soon as the pawl collapsed into one of the correspondingly adjusted notches is.

In a mounted reversible plow of the type mentioned above, however, in which the pivoting movement of the rotating piece about its axis is not carried out by a free device for adjusting the lateral
Inclination of the plow bodies of mounted reversible plows

Falling movement, but when lifting the ploughshare (by means of power lifts) is effected, namely by a driver, which as a result of its control by its driver transmission from the power drive when lifting one of the ploughshares and pivoting the rotating piece regardless of the lateral inclination of the plow always carries out a constant stroke, the above requirements are so far has not been taken into account for the following reasons:

The well-known driving gear determines the timely disengagement of the locked pawl regardless of the position of the detent, always before the start of the lifting movement of the driver. But there is this spring-loaded pawl to engage again before the end of this driver stroke free into the other rest.

An adjustment of the notches corresponding to the transverse inclination of the plow would therefore be due to the then a later started but constant stroke of the driver or the rotating piece premature locking of the rotating part due to the locking pawl that engages at the angle of the spring before the pivoting movement of the rotating piece determined by the constant stroke of the driving hook would be ended, resulting in the risk of breaking either the detent means or another part influenced by the constant stroke follows.

For this reason, so far with mounted reversible plows of the type mentioned above, the Notches adjusted, but the ploughshare, and for this purpose the ploughshare by means of a with respect to the transverse inclination adjustable, preferably fixable by clamping at different inclinations

to effect the known, not shown, driver gear 65, sits on each of the detent carriers 4 and 5 attached for swiveling the rotating piece. each a fixed pin 14 or 15, with which

Around the bearing pin 1 are a driver arranged between these pins in the direction of travel of the tractor behind the rotating piece 2 - 16 cooperates, which at its lower end

Pin 15 when pivoting the rotating piece in the clockwise direction of the Fi g. 1, when the plow 2 b was in the locked position and is being lifted out. If this were not provided automatically and at the correct angle with the setting of the locking carriers 4 and 5 in advance of adjustment of the pins 14 and 15, then when the driver 16 is lifted upwards, part of the driver mechanism would be damaged by the pawl 20 engaging prematurely .

As a rule, it is expedient to have both locking supports 4 and 5 or both pivot pins 14 and 15 to pivot about the axis of the journal 1 by the same pivot angle, but in opposite directions to one another. Such a setting can be achieved by the

hook-shaped end portions 16 a and 16 b has. Of the
Driver 16 is at its upper end by means

this pivotally mounted on the coupling, after acts that the driver 16 with its hook end protruding pawl lever 20 α (Fig. La) in arrow 20 16a or 16 b is pivoted a slightly longer idle stroke alignment, so that the pawl 20 leads out until this end of the hook is disengaged on the pin 14 or 15 of the associated catch. After that attacks, but otherwise has no influence on the stroke movement of the driver, which always takes place with the desired pivoting movement of the rotating piece 2. constant stroke length, can take place, the same as for FIG. 1 is true

much, which position of the grid supports 5 or 4 (or 25 35 also for the further described below or 24) and the associated pin 14 or 15 - in embodiments of the invention in which the F i g. 1 according to the setting of the setting spindles 6 and 7 - takes.

In front of and behind the driver 16 is shown as a guide for its in the plane of the FIG. 1 subsequent 30 Pivoting is provided in each case with a guide bar, the rear of which is shown at 16c in FIGS. 1 and 2 is, and each of which is hinged at one end to the pin 15, while the

the other end with an elongated hole over the pegs 14 35 movement by means of clamping screws 27 and 28, respectively, are clamped, each by a guide bracket 29

On the support plate 2 c is symmetrical to the or 30 reach through the latching carrier. Rotary piece attached an approach 19, on the free As in the embodiment according to F i g. 1 sits

At the end of a tension spring 18 is hooked in, which with its each of the pins again designated 14 and 15, respectively the other end at the center of the driver 16 engages an arm that projects toward the rotating piece 2. Depending on the position of the rotating piece 2, the corresponding locking carrier is used, so that it is its angle the driver either away from the spring 18 when it is moved over the detent arch against the right pin 14 (as shown in Fig. 1) 26 participates, or pulled against the left pin 15. F i g. 2 shows a similar position of the right one

If there is - on level ground - one to the wheel 45 plow as in FIG. 1, in which the pawl 20 axles The vertical plane of the tractor is also perpendicular to FIG right to the ground to be plowed, so that will be locked.

Detent carrier 4 and 5 by means of the adjusting spindles 6 It is now assumed that in this position the

and 7 to the large distance of their notches from one clamping screw 28 loosened and the rotating piece 2 adjusted to each other. If, however, one should now, for example, go through the 50 counterclockwise around the armpit into the plane EE in FIG. The right-hand plow - not shown in FIG to be pivoted in such a way relative to the rotating piece 2, set. In this case, the detent carrier 24 moves that the ploughshare 2α or 2b, as for the share2α 55 also in the dash-dotted line shown in Fig. 2 F i g. 1, perpendicular to the ground for the ninth position.

sentence. arrives and is locked in the operating position. At the same time, the pivot pin 14 is opposed

With this adjustment of the notch carriers around the loader clockwise into the one shown in dash-dotted lines gerzapfen 1 is now also the position 14 'pivoted according to the invention, where he, as he, as in Pin 14 and 15 at a corresponding angle 60 of the embodiment of FIG. 1, in the elongated hole of a with respect to the locked position of the pawl 20 engages guide bar 16 c, this takes it. Of the

For the sake of simplicity, this is again a mechanical drive gear is used as a basis for controlling the driver 16 with a constant stroke.

In contrast to FIG. 1 are shown in FIG. 2 the Notch carrier 24 and 25 pivotable not hb -dem Pin 1, but mounted on a detent arch 26 welded to the rotating piece 2, on which they turn in the desired end position

adjusted. This avoids that when, for example, the plow 2a was in use and the stroke of the driver 16 upwards the rotating piece in FIG. 1 pivoted counterclockwise, the pawl 20 prematurely engages in the detent 4 α under the action of the spring 20 b before the stroke of the driver 16 b is ended. The same applies to the

Driver 16, on which the spring 18 attached to the notch arch engages, follows the movement of the Pin 14. At the beginning of the stroke of the driver 65, it now initially makes a small idle stroke, until its hook 16 a engages the pivot pin 14. As a result, this driver 16 can be his lead to the end of a constant stroke, although the

Rast 24 α has moved counterclockwise relative to the catch 25 a and thus the angular path the angle piece has become smaller when turning the plow or the rotating piece 2.

The fact that the pivot pin 15 is not seated on the elbow 2, but on the associated latching carrier 25, can also occur during the reverse rotary movement of the elbow 2 clockwise when the hook 166 with a constant stroke on the pin 15 attacks, no damage to the gear occurs because of the rotation mentioned above of the elbow counterclockwise with the detent carrier 25 held and thus also held Pin 25 of this is displaced relative to the angle of adjustment of the elbow Has.

The same applies if the inclination of the left ploughshare is thereby also applied to the detent carrier 24 should be set that the clamping screw 27 is loosened and the rotating piece 2 clockwise ao is rotated while the pawl 20 is locked in the catch 24 α. In this case, too, results automatically the desired relative movement of the pins 15 and 14 by the same adjustment angle as for the detent 24 α, so that the driver 16 does its turning work with a constant stroke execute on rotating piece 2 bans, although its angle of rotation has been reduced.

In many cases where the tractor is plowing with the left wheel in a furrow just as deep as running with the right wheel, it is advisable to adjust both ratchet supports on one smaller angle of rotation of the contra-angle both clockwise and counterclockwise set simultaneously with one and the same adjustment device for the same angular path. This possibility gives the embodiment according to FIG. 3 for one of the F i g. 2 similar construction and after F i g. 4 for one of the F i g. 1 similar construction and storage of the grid supports.

According to FIG. 3, both latch carriers are mounted to pivot freely on to the plate 2 of the rotary piece welded c 2 notch 26 Bow 24 and 25th As with F i g. 2, the lower arm of each grid carrier carries one pivot pin 14 or the other 15. A link 31 or 32 is hinged to the bracket 29, 30 leading to the grid carrier on the notch arch a bolt 34 are articulated. The spindle nut is mounted so as to be longitudinally displaceable in a guide 35 which is welded to the plate 2 c and protrudes radially from it, by means of a threaded spindle 36 with a hand crank 37 which is rotatably mounted at the outer end of the guide 35. As can be seen, by rotating the spindle 36, the links 31 and 32 are pivoted with respect to the detent supports 24, 25 and bent out of the extended position or returned to it, so that the detent supports move in opposite directions on the detent arch by the same angular path against each other or away from each other move. Otherwise, the pivot pins 14 and 15 work in the same way as in FIG. 2 described with the (not shown) driver 16 and work the notches 24 ″ and 25 a in the same way with the (not shown), according to FIG. 1 a provided pawl 20 together.

In the embodiment according to FIG. 4 are, as in Fig. 1, detent carriers 4 and 5, each with a detent a and 5 a are provided, which are pivotably mounted about the pin 1 and the pins 14 and 15, respectively wear. In place of the separate threaded spindle 6 or 7 of FIG. 1, a left-hand and right-hand thread double threaded spindle 38 is provided, whose threaded parts provided at the ends in each case a spindle nut articulated on the latching carrier 4 and 5, respectively 39 or 40 intervene. The middle part of the double-threaded spindle is on one radially of the Angle plate 2 c outwardly projecting two-legged extension 41 rotatably mounted and by means of a handle 42 rotatable. As can be seen, when a rotary movement is initiated, the mode of action is the thread mirror 38 with respect to the notches 4 a and 5 α and the pins 14 and 15 the same as in Fig. 3.

In the event of inaccuracies in production or bending, it can be provided in all embodiments that the pin (14 or 15) is somewhat adjustable with respect to the associated detent on the detent carrier.
