Agricultural implement with tines, in particular arable thorns

Me firing refers to an agricultural implement with tines, in particular a field tree with a machine frame and tine holders, which under the action of a restoring force generating elements, in particular Tension springs are in place.

The task of the! Price increase is to create a device of this type create whose prongs swing out according to the forces acting on them. Are the forces acting on the tines small, then should act on the individual prongs

- 2 -

Restoring forces can be comparatively small. Conversely, "with high resistances, ie with relatively heavy soils, the the restoring forces acting on the prongs must be comparatively large.

This object is achieved according to the invention in that swivel members are articulated on the machine frame with each pivot member a tine holder is articulated that the pivoting movement of each pivot member in the stop limiting one direction is provided, and that after reaching the stop position with further enlargement the force acting on each prong pivots the associated prong holder relative to the pivot member.

With the device according to the innovation, with on the machine frame and tension spring hinged to one end of each tine holder form the two articulation points of each tension spring and the articulation point of each pivot link or the articulation point of the tine holder corner points of a triangle, the height of which is different is.

For a device with a machine frame designed as an L-profile serves as a stop on one leg of the machine frame.

According to a further feature of the innovation, a lock is provided, which each prong in the inoperative position locked. Advantageously, the lock consists of a hook connected to the machine frame, which is in the locked position engages in a recess machined into the tine holder.

The agricultural device according to the invention is explained in more detail below with reference to the drawing. In this show in a purely schematic way:

Fig. 5 is a view, partly in section,

of the tiller according to the control in the inoperative position.

1 with the machine frame is designated "which" in the embodiment shown in the drawing as an L-profile is trained. A pivot member 2 is articulated to the machine frame 1, to which the tine holder 3 is in turn articulated is. It is clear that the weed according to the innovation consists of several units lying next to one another, like them are shown in the figures of the drawing.

The tine holder 3 is connected to the machine frame 1 via an element generating a restoring force, for example a tension spring 4j connected.

The tine, which is firmly connected to the tine holder 3, is denoted by 5.

As can be seen from Figure 5 of the drawing, a lock is provided which holds each prong, e.g., 5j, in the inoperative position locked. When cultivating row crops, it is essential to put one or the other tine in the out-of-service position to convict.

Me locking consists expediently of a hook 6, in the locked position in one in the tine holder 3 ~ worked recess 7 engages.

As can be seen from Figure 3 of the drawing, Mlden the articulation points 8,9 of the tension spring 4 and the articulation point 10 of the pivot member 2 are the corner points of a triangle with the height h.

In the stop position according to Figure 4 are the Articulation points 8.9 of the tension spring 4 and the articulation point 11 of the tine holder 3 on the corner points of a triangle with the Height H. Figures 3 ″ and 4 clearly show that the height H is greater than the height h.

The method of operation of the agricultural device according to the innovation is as follows:

In the rest position, the ropes of the device assume the position shown in FIGS. The swivel link is here 2 approximately perpendicular to the machine frame 1; the tine holder 3 forms approximately a right angle with the pivot member 2.

When the agricultural implement is moved, the tines, e.g. 5, are subjected to a force against the direction of movement exercised, which deflects the prong 5 according to its intensity. If this force is relatively small, the pivot member 2 pivots only slightly, with no relative movement taking place between this and the tine holder 3.

- 6 -

U increases the intensity of the acting on the prong 5 Force, the pivot member 2 reaches that shown in FIG te position in which the pivot member 2 is against the vertical leg of the machine frame 1 acting as a stop applies. If the pivot member 2 and the tine holder 3 were to form a rigid unit, then "with greater forces a further pivoting of the pivot member 2 and thus the Tine 5 impossible! Damage to the prong 5 would be immediate PoIge of this.

But since the tine holder 3 opposite the pivot member is relatively pivotable, the prong 5 can pivot even further and thereby reaches the position shown in ligur-4.

Should one or the other tine 5 be functionally switched off, which is necessary when working on row crops is, it is sufficient to swing out the corresponding prong until the hook 6 engages in the recess 7.
