Subsoiler. Patented in the German Empire on September 21, 1923.

In many soils, plowing too deeply is in the interests of drainage is desired, dead soil brought up. This makes the income of this Fields significantly impaired. Major farmers have therefore started To plow such soils only shallowly, on the other hand the so-called subsoil as deep as possible loosening in order to keep the soil waterlogged (especially in sandy soils) to regulate.

For this purpose, the various

Claims (3)

the most subsoilers have been built, some of which are solid, some of which are movable with the plow body or plow frames, almost all of which suffer from suddenly Large resistances that arise, such as Stones, roots, etc., cannot move quickly enough. The purpose of the invention is now to these the previously known subsoilers ίο to eliminate adherent deficiency, namely this happens primarily because the licking effect, deep in the Arable soil reaching tines is raised when dodging. As a result of the combine lea Movement, the tines are not only held back when they strike against an insurmountable resistance, but at the same time lifted and therefore gives way to the obstacle upwards, this to some extent surpassing it. The prong is advantageously designed as an angle lever, the pivot point of which can deflect upwards and its legs finds its base on a fixed role, on which it finds its base when evading of the tine unrolls. The pivot point of the angle lever can be in one arm of a double lever be arranged whose other arm is under the action of an adjustable spring j spring or similar device that presses the tines into the ground and the evasive movements take place against their effect. The drawing shows an embodiment of the subject matter of the invention, represents. I. On the plow body 1, which is fastened to the frame 2, a plate 4 is arranged adjustable by screw bolts 3, on which a double lever 6 is rotatably mounted at 5. On one arm 7 of the double lever 6 engages | an energy store, for example a spring 8 ^! which you find abutment at 9 and whose | Voltage can be regulated. In the other arm 10 of the double lever 6, the tine 12 equipped with a coulter ix is rotatably supported at 13. The prong 12 has the shape of an angle lever, the free leg 14 of which is curved at j 15 and is supported with this curve against a roller 16 attached to the plate 4. A bracket 17, which is essentially adapted to the shape j of the plate 4, serves as a guide for the prongs 12. The operation of the device is as follows:; Normally the prong 12 takes the | drawn in solid lines in the illustration Position a, is so pressed by the spring 8 into the ground and so does the Loosening of the subsoil. If the crowd now meets an insurmountable obstacle, for example a stone or a root, then the prong swings backwards about its pivot point 13. Simultaneously but the curve 15 rolls on the roller 16 so that the double lever 6 against the Effect of the spring 8 is pivoted. As a result, the fulcrum 13 moves in a cure after 13 '. Take it as a result the prongs and the interacting parts the position shown in dashed lines one that shows that the flock not only swung backwards, but is raised at the same time, so that there is a guarantee that the obstacle is exceeded will. . Instead of the double lever 6, a slot guide could possibly also find pivot point 13, just as a roller can be provided on the leg 14, which cooperates in the corresponding sense with a cam fixedly arranged on the plate 4. In other respects constructional modifications can be made without falling outside the scope of the invention, ₅ g provided that the tines the desired motion is imparted thereby. Godfather τ-An Proverbs: i. Subsoiler with tines swinging out against spring pressure, thereby characterized in that the prong executes a swinging movement around its pivot point when dodging and this in turn swings around a point fixed on the frame. 2. Subsoiler according to claim 1, characterized in that the tine is designed as an angle lever, the J ₀₀ pivot point of which dodge upwards canoe and whose free leg finds its support point on a fixed roller, on which it rolls when evading the tine. 3. Subsoiler according to claims ι and 2, characterized in that the pivot point of the angle lever carrying the prongs is mounted in one arm of a double lever, the other _11Q arm is under the action of an adjustable spring or similar device. 1 sheet of drawings.
