Device for deep loosening of soils!

r t

This object is achieved in that the loosening coulter is hinged to at least one of the pub and the loosening coulter Handlebar is pivotably mounted on the Euü and dab the or the for Storage of the loosening coulter on the foot provided handlebars based on the direction of pull arrangement completely within. the contour behind the Loexerungsschar against the upcoming one Floor are covered.

The pivoting movement is due to the link or links provided the loosening coulter is no longer bound to a fixed pivot axis and thus to a sinusoidal movement, in particular the Loosening coulter are predisposed to movements in which the upward movement is not, as with the sinus movement, the downward movement symmetrically corresponds. This makes it possible, through the geometric design of the handlebar (s), to control the sequence of movements to optimize the loosening coulter in terms of the task at hand.

In a device of this type known from OS 1 918 670 the loosening coulter performs a pivoting movement around one at the front end of the foot and approximately following the front third the loosening coulter has a horizontal swivel axis located transversely to the pulling direction. That leads to the this Pivot axis protruding towards the front end of the Loosening Schör performs an up and down movement about this pivot axis and the leading edge of the loosening coulter moves the cutting edge - up and down through the soil. The cutting edge describes as a result, a sinusoidal and therefore extremely long path through the ground in relation to the effective distance traveled therefore extreme wear and tear. In addition, when the front end of the loosening coulter swings down, it pushes the underneath the soil together, which increases the effort required for loosening.

The object of the invention is to design a device of the type mentioned at the beginning in such a way that the energy expended for the movement of the loosening coulter is better for the desired loosening of the soil is exploited and excessive abrasion, in particular the cutting edge.

• cn ι ι ι ι .ι /

The link (s) are by their arrangement in the shadow of the loosening coulter against the slimy and blocking They are protected against the effects of the ground they drive through and therefore do not exert any additional load on the pulling force.

The guidance of the loosening coulter along its up and down movement can be made safer if the loosening bar is pivotably mounted on the foot, both at the front and back, with a handlebar articulated on the foot and on the loosening coulter completely through the Loocerungsschar against the upcoming one Soil are covered and the loosening coulter is hinged to the coupling rod. With two links are further manifolds possible with regard to the design of the periodic movement of the loosening coulter, which favors the desired optimization.

The protective effect of the loosening coulter can still be favored by one on the edge of the loosening coulter in the direction of the Foot them '., Extending apron.

In the case of Riiokwär ί, οΓα.'υι ö necessary for the purpose of kangierens or when lifting the leg out of the ground, the foot may move backwards through the ground. For this For this purpose, a protective protrusion on the side of the foot is recommended in relation to the direction of pull behind the foot on this side outstanding handlebar, through which then this handlebar at least partially before the direct action of when reversing driven ground is protected.

The invention will now be exemplified with reference to the accompanying drawing explained in more detail.

The parts not shown in Figures 5 to 12 are

Exemplary embodiment shown in FIGS. 1 to 4.

In Figures 1 to 4, mil ^ o is the rear end of an as

The angle 46 is in the example 28 degrees. The connector 24 is supported between the control arm 23 and the mounting frame.

The leg is supported by the leg links 23 and 22 in connection with the connector 24. By increasing the length of the connector 24, the leg 1 can be lifted. In this way, the depth of penetration into the ground can be adjusted and the leg can also be pulled completely out of the ground

into an ineffective transport position, which is indicated in Figure 1 by "the dash-dotted line 11. In this transport position the curved leg hugs the rear contour of the tractor and wins thereby an optimal position for the center of gravity of the entire tractor. In this transport position, the leg is opposite the fully drawn functional position not only raised but also swiveled by about 3o degrees. This coupled Raising and pivoting is achieved by appropriately dimensioning the leg links 23 and 22 and the arrangement of their bearings 39, 40, 43 and 44 scored.

With 1o one of the tractor drive rotates around the axis 17 Drivable eccentric designated, which drives a coupling rod 9 via a second coupling rod 15 in an oscillating manner. The two Coupling rods are articulated with one another and with a pivot bearing 5o with a pivot axis perpendicular to the plane of symmetry 47 a link 51 is connected, the other end of which is mounted in a pivot bearing 52 on the leg 1. If the Eccentric 1o rotates, so the first coupling rod 9 performs oscillating Movements from top to bottom in the direction of double arrow 53.

At the top of the foot 38 is a front link 55 and behind it a rear link 56 is articulated in a pivot bearing 57 »58 each. A loosening coulter 59 is attached to these two links 55, 56, specifically on the link 55 by means of the pivot bearing 60 and on the handlebar 56 by means of the pivot bearing 61 in which

coaxially the lower end of the first coupling rod 9 is articulated with the loosening coulter. In the functional position shown, the second coupling rod 9 is in its upper extreme division. In this position, the connecting line 62 of the axes of the two swivel bearings 57 extends almost perpendicular to the working plane bj> the loosening coulter 59.The corresponding connecting line 64 between the axes of the swivel bearings 58 and 61, on the other hand, extends at a large obtuse angle 65 to this working plane 63 · The center distance of the pivot bearings 58 and 61 is more than twice as large as the center distance of the pivot bearings 57 and 6o. The loosening coulter 59 has a work plate 66, the surface of which is the work plane 63, which is inclined to the direction of pull, according to arrow 31, and which is otherwise perpendicular to the plane of symmetry 47.

As can be seen from FIG. 4, the two links 55 and 56 with their bearings 57> 58, 60 and 61 are located in relation to the direction of pull - that is, the direction opposite to arrow IV behind the loosening coulter 59 "in relation to the direction of pull within the contour 81 of this loosening coulter visible in FIG. In this way, these two links 55 and 56 and their bearings 57, 58, do una 61 against the. pending soil covered by the Locicerungsschar, while the leg moves in the pulling direction according to arrow 31 through the soil. To further protect these links and their bearings, protective aprons 67, 68 that are attached to the side of the worktop 66 and point backwards are provided. With b9 and 7o two lateral projections in the heel area of the foot 33 are designated, which are arranged in the rearward extension of the forked handlebar 56 and protect this handlebar when the foot moves against the pulling direction 31 through the soil. As can be seen from FIG. 4, the link 56 is forked at its two ends and overlaps on the one hand the Fuia 33 and on the other hand the coupling rod y. The rear end of the loosening coulter is iiebenfa * lls bifurcated and engages around the handlebar 56. The handlebar 55 · i ^ji st not bifurcated and is received in the bifurcated toe 72 and a fork 71 in the Locxerungsschar.

Rear links 56 with the associated bearings are designed mirror-symmetrically to the plane of symmetry 47. The worktop bb extends broadly across the plane of symmetry 47? on the other hand, the coupling rod 9 and the leg 1 are narrow transversely to the plane of symmetry 47. The effect of the grind with its loosening coulter is as follows.

If the leg is in the drawn functional position in the direction of pull pulled through the earth, dar ^ i will normally only one force exerted on the leg in the direction of the plane of symmetry, namely because the worktop 66 is transverse to the plane of symmetry is very wide, whereas the coupling rod 9 and the leg 1 are very narrow transversely to the plane of symmetry, this force becomes mainly exerted on the working plane 63 of the worktop 66 and a component of this force pulls the leg into the drawn vertical position. If a force component outside the symmetry plane acts on the worktop, for example because the loosening coulter hits a stone, then the whole leg can swing around the pendulum axis 45 of this force component yield and give way to the side, in the extreme case in the in Figure 1 and 2 by the dash-dotted line 73 indicated position. The normally exerted on the loosening coulter by arrow 74 during further operation The indicated force strives to drive the leg back into the drawn symmetry position. Remarkably, that with a pendulum swing the transmission of the eccentric movement not interrupted by the coupling rods 15 and 9, and if at all, then only slightly shifted. The warehouse of the eccentric and the swivel bearing 5o "offer enough bearing play, to absorb the displacements caused by the pendulum movement.

If the eccentric is driven 1o during operation, i.e. when driving forward is then caused by the double arrow 53 as shown Up and down movement of the coupling rod 9, the loosening coulter 59 is pivoted up and down. The back end of the The loosening coulter is pressed down and the forward one
