KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die vorliegende Erfindung betrifft einen Pflug, der als ein- und mehrschariger Pflug verwendet werden kann, sich durch die leichte und genaue Einstellung des Furchen- und Laufrades vermittelst eines Hebels auszeichnet und die sichere, stets geradlinige Führung durch Anordnung des Zugangriffes an einem mit dem Pfluggestell fest verbundenen, aufserhalb des letzteren liegenden Punktes ermöglicht.The present invention relates to a plow which is used as a single and multi-blade plow can be used by the easy and precise adjustment of the furrow and impeller by means of a lever and the safe, always straight guidance through Arrangement of the access handle on a firmly connected to the plow frame, outside the the latter lying point allows.

Ein Pflug, bei welchem das rechte Vorderrad in der Furche geht, wird nur dann richtig arbeiten, wenn dieses Rad (das Furchenrad) mit dem untersten Berührungspunkte in die Horizontale der Pflugsohle fällt.A plow with the right front wheel in the furrow will only then be correct work when this wheel (the furrow wheel) with the lowest point of contact is horizontal the plow sole falls.

Ist z. B. ein Pflug mit ungleichschenkliger Winkelachse auf eine bestimmte Furchentiefe richtig, d. h. so eingestellt, dafs das Furchenrad seine Stellung auf der Horizontalen der Pflugsohle hat, so wird dieser Pflug auch nur in dieser einen Stellung richtig arbeiten. Bei einer Verstellung des Landrades wird auch das Furchenrad in Mitleidenschaft gezogen (weil beide auf einer Achse sitzen), d. h. aus der Horizontalen der Pflugsohle fast um ebenso viel herausgehoben oder gesenkt, wie die senkrechte Hebung des Landrades beträgt. Soll nun dieser Pflug tiefer arbeiten, so wird das Furchenrad über die Horizontale der Pflugsohle fast ebenso viel hinweggehoben, als das Landrad über das Terrain. Das vordere Schar arbeitet demnach um diese Differenz tiefer wie das hintere Schar.Is z. B. a plow with a non-isosceles angular axis to a certain furrow depth correct, d. H. adjusted so that the furrow wheel is positioned on the horizontal of the Has the plow sole, this plow will only work properly in this one position. at an adjustment of the land wheel will also affect the furrow wheel (because both sit on one axis), d. H. from the horizontal of the plow sole almost by the same much raised or lowered, as is the vertical rise of the land wheel. Intended to Now work this plow deeper, so the furrow wheel will be above the horizontal line of the plow base lifted almost as much as the country bike over the terrain. The front crowd therefore works by this difference deeper than the rear coulter.

Will man diesen Uebelstand vermeiden, soll also der Pflug für verschiedene Furchentiefen gleich gut arbeiten, so mufs jedesmal ein anderes Landrad aufgesteckt oder der Schenkel desselben verkürzt bezw. verlängert oder aber beide Schenkel zu einander verdreht werden.If one wants to avoid this inconvenience, the plow should be used for different furrow depths work equally well, so each time a different country bike or the thigh has to be attached same shortened respectively. extended or both legs are twisted to each other.

Anders verhält es sich bei dem den Gegenstand vorliegender Erfindung bildenden Pflug.The situation is different with the plow forming the subject of the present invention.

Man kann bei einem Pflug, der z. B. auf 100 bis 250 mm Tiefgang bestimmt ist, mittelst des Winkelhebels das Landrad um etwa 150 mm heben und senken, ohne dafs das Furchenrad mehr als 5 mm über bezw. unter die Horizontale der Pflugsohle tritt.You can with a plow that z. B. is determined to a draft of 100 to 250 mm, mean of the angle lever raise and lower the land wheel by about 150 mm without doing this Furrow wheel more than 5 mm over or. steps below the horizontal of the plow sole.

Abgesehen von der einfacheren Handhabung dieses Pfluges ist dies ein hervorragender Vorzug bei verschiedenartiger Bodenbeschaffenheit, wo der Pflug während des Ganges tiefer oder flacher gestellt werden mufs, ohne dafs derselbe schief geht.Aside from making this plow easier to use, this is an excellent asset with different types of soil, where the plow is lower or lower during the course must be made flatter without it going wrong.

Auf der Zeichnung zeigt Fig. 1 den neuen Pflug, von der Seite gesehen, in der Arbeitsstellung, während Fig. 2 die gleiche Ansicht dieses Pfluges in der Transportstellung darstellt. Fig. 3 ist die obere Ansicht und die Fig. 4 bis 7 sind Einzelheiten des Pfluges.In the drawing, Fig. 1 shows the new plow, seen from the side, in the working position, while Fig. 2 shows the same view of this plow in the transport position. Figure 3 is the top view and Figures 4-7 are details of the plow.

Auf dem Rahmengestell R, Fig. 1 bis 3, sind zwei gekröpfte Achsen α α¹ gelagert, auf denen sich die beiden Räder, das Furchenrad F bezw. das Landrad L befinden. Diese beiden Achsen werden derart von dem Winkelhebel W bewegt, dafs die Achse α des Landrades beim Einrücken des Pfluges, Fig. 1, eine gröfsere Winkelgeschwindigkeit annimmt, wodurch eine Voreilung des Landrades L eintritt und so durch die verschiedenartige Stellung der beiden Vorderräder die Furchentiefe bestimmt wird.On the frame R, Fig. 1 to 3, two cranked axes α α ^{1 are} mounted, on which the two wheels, the furrow wheel F respectively. the Landrad L are located. These two axes are moved by the angle lever W in such a way that the axis α of the land wheel assumes a greater angular velocity when the plow is engaged, Fig. 1, whereby the land wheel L advances and thus determines the furrow depth through the different positions of the two front wheels will.

Die beiden Schenkel 5 und s^] des Winkelhebels W, welche mittelst der verstellbaren Schubstangen 5 und S¹ die beiden AchsenThe two legs 5 and s ^{] of} the angle lever W, which by means of the adjustable push rods 5 and S ^1, the two axes

Claims

move, are set so that the leg s ¹ , which engages the furrow wheel, stands on the dead point as soon as this wheel has reached its correct position, ie the horizontal of the plow base. Since in this position, Fig. 1, the movement of the furrow wheel in the vicinity of the dead point is very slight, but the action of the leg on the land wheel is greatest, the furrow depth can be adjusted correctly by simply moving the angle lever W. possibly borrowed.

The axis a ^{1 of} the furrow wheel can be displaced in the guide block f, FIG. 3, and in the adjusting rings h . This shift allows the track of the furrow wheel to be changed, so that the single-furrow plow can also be used as a two-furrow plow (see the dotted position in Fig. 2) in such a way that the right wheel goes in the last furrow even with this use, without coming into any connection with the lever mechanism.

It is not necessary that the axis a ^{1 of} the furrow wheel F consists of one piece, but the leg a ² carrying the furrow wheel can be shifted on the straight part of the axis a which must be lengthened in this case.

The two push rods S and S ¹ , which transmit the movement of the hand lever W to the axles, are divided approximately in the middle (see FIGS. 4 and 5) and can be adjusted by means of the screws i in such a way that one half of them can be adjusted there is a long hole in which the screw bolt can be slid. By tightening this bolt, the nose η of one half of the push rod is pressed into any notch in the other half, and the two ends of a push rod are joined to one another in such a way that they cannot be displaced.

The tie rod Z, Fig. 6, consisting of T-iron, is arranged adjustable at the front on the cross piece of the frame by means of claw k and setting iron e , whereas it is fastened at the rear in the various holes of the bracket / by means of bolts. By virtue of this device it is possible to give the pulling device a fixed point of application at the hook H, which is still in front of the wheels - the actual guide points of the plow - in any direction of the room, both to the right and to the left, high and low , forwards and backwards, parallel and diagonal to the frame.

Is z. B. plowed wide with three horses, with the line of pull on the left outside the frame, the pull rod Z must be placed diagonally (Fig. 3, dotted position), otherwise the horses will always pull the ploughshare to the land side and thereby the furrow Always make it wider and wider, whereas with a diagonal tie rod position the ploughshare can be guided exactly in the furrow direction.

This pulling device gives the plow good guidance, as it would with a loose chain, where the fixed point of application must be within the boundaries of the frame, not possible is.

This makes the plow especially useful when plowing steep slopes and when plowing wide and turning is guided very safely. Furthermore, turning the plow around is made much easier by this tow hook.

Pat τ claims:

ι. In plowing the use of a cranked axle (aa ^l ) for the two front wheels (LF), which are moved by an angle lever (W) equipped with two legs (see V) by means of adjustable push rods (S and S ¹ J) in such a way that one is different large adjustment of the two wheels is possible for the purpose of determining the furrow depth, the leg (s ^ J of the angle lever, which engages the furrow wheel (F) , stands on the dead point as soon as this wheel has reached its correct position, i.e. the horizontal of the ploughshare , for the purpose of enabling the plow to move out and in by means of a single lever.

2. On plows with the device specified under 1., the axis (a ^l ) of the furrow wheel, which is displaceable in its longitudinal direction to the axis (a) of the land wheel, in order to be able to change the distance between the two front wheels as required and thus a single-blade plow into a two-blade plow to be able to transform in such a way that the furrow wheel with both types of use can always be placed in the last furrow in order to have its guidance in this.
