Subsoiler. Patented in the German Empire on June 17, 1925.

The well-known subsoilers for plows usually consist of one or more knife-like, rigid tines which are pivotably arranged in the plow body to to be able to evade resistance when starting up; they are by spring force storage held in their working position or returned to it after being pivoted away. These spring force accumulators were

ίο so far entirely or to a large extent within of the plow body, always below the plow frame, in which arrangement the Feather parts heavily contaminated or clogged by parts of the earth, herbs or roots subject to what the effectiveness of the energy storage in question and thus when occurring high resistance, swiveling the subsoiler out of the working position or its return to the

this prevents working position after swiveling away.

In order to eliminate these possibilities, it has already been proposed to use the spring force accumulator to be placed above the plow body or plow frame carrying the ploughshare, however, it was given an upward sloping position. This magnifies the height of the plow part formed by the subsoiler is considerable and makes it a bulky device, which is particularly annoying on a multi-share plow several subsoilers works.

Therefore, according to the invention, the spring force accumulator is located above the plow body or plow frame given a horizontal or approximately horizontal position, being an abutment attached to an attachment or sprue of the plow body or plow frame is and its other abutment engages with the pivotable prongs connected to transmission members. These transmission links become light and insensitive parts in their mode of action designed by between the prongs and a double-armed attack on the energy storage device Lever a simple pull rod as a

*) The patent seeker stated as the inventor:

Eduard Müller in Düsseldorf.

Intermediate link is placed in each position and with each movement of the tine is only used on train.

The drawing illustrates an exemplary embodiment of the invention, and show it:

Sitting on the plow body α , rotatable about the pin b , is the double-armed Zinkemihalter c, which carries the vertically adjustable tines d at the rear end; on the other hand, his front arm is articulated to one end of a pull rod e. The pull rod e is articulated in / on the angle lever h which can be pivoted in a bearing block of the plow body α. Between the upwardly directed ao arm h ^{1 of} the angle lever h and an arm ij that sits on top of the jointer pocket ä ¹ cast on the plow body a , there is a spring force accumulator k, the spring of which is secured against dirt in a housing closed on all sides, switched in such a way that it is always approximately horizontally above the plow body α both in the working position of the tine d (Fig The ground thrown up by the plow remains without significantly increasing the height of the plow.

Of course, the connecting links between the tine holder c and the spring force accumulator k, which, even acting on compression or tension, consist of a blade or screw

spring can exist, also designed and arranged differently, but always so that apart from the parts that are used as a lever (z. B. the parts c and h) are claimed to bend, otherwise only to train stressed transmission members such. B. on the type of tie rod e, come to use. This makes it possible to make the cross-sectional dimensions of these parts simple and small, and bending and kinking, as can occur with parts subject to pressure, is excluded.

Claims (1)

Patent Claims: i. Subsoiler with rigid tines that counteract the action of an above of the plow body or plow frame carrying the ploughshare, the spring energy store swing out upwards can, characterized in that the energy store with its one spring abutment attached to an attachment or sprue of the plow body or plow frame is and, with its other abutment connected to the pivotable prongs Attacking transmission links, a horizontal or approximately horizontal one above the plow body or plow frame Position. 2, subsoiler according to claim 1, characterized in that the pivotable Prongs and the spring force accumulator or the transmission levers connected to them are connected to one another by intermediate links that are only subjected to tension when plowing in any working position will.
