DE834787C - Device for plowing the verge of land - Google Patents

Description

The farmer knows that with the known ones pulled or carried by motor tractors Plowing the verge cannot be turned without driving on the property of the resident to have to. This fact works out as an evil.

Since means for eliminating this deficiency have not become known, the inventor has the Task set to construct a device,

ίο their application plowing the verge along the property line. light without the plow and its motor Traction means must be steered over the adjacent property. According to the invention, this Work carried out by at least one ploughshare that can be adjusted transversely to the direction of travel is that the furrow he has drawn is outside the lane of the plow or his Traction means runs. So if you want z. B. plow a verge, then tighten the ploughshare of the plow in the specified manner or brings a previously out of service Auxiliary ploughshare in working position, while the other unneeded shares are swung up or removed from the Pfluggrindel.

The ploughshare or plowshares are arranged on transverse arms. As a cross arm carrier (the Pfluggrindel to serve. It is also possible, often even expedient, to place the transverse arms directly on one To store or center the wheel axle of the plow.

The installation of a known device for changing the coulter angle and thus the The depth of the furrow completes the device. As has been found, a novel one is suitable for this

Construction in which one, but advantageously two, coupled to the drive of the device Swivel levers are attached to the cross arms. These pivot levers are on both sides of the Transverse arms are arranged with the fist connecting the Pfluggrindel and together carry the spindle nut the threaded spindle for adjusting the furrow depth. At the same time they prevent the axial Shifting of the pivotable cross arms in the plow leg.

The invention is applicable to both single and multi-share plows. Reversible plows too can be equipped with it.

In 'the drawing are explanatory sketches and exemplary embodiments of the subject matter of the invention shown schematically. It shows

Fig. Ι two plots by two motorized plows (Bed plowing) are processed, in plan view. A plow is turning the ao the verge of one plot employed, while the other plow the middle section of the second Ackers worked;

Plots that are worked by plows that turn with one left and one to the right Ploughshare are provided. In the plow that processes the edge strips, the ploughshares turn the Clods inwards, with the device plowing the middle section, however, in the usual way Outside;

In the drawings, plow features which are necessary for practice but are irrelevant to the invention have been omitted in order to be able to clearly show the arrangement of the transverse arms. The plows essentially consist of the plow shaft 1, the wheels 2 and the ploughshare 3 or 2> ^L (left ploughshare) and 3 * (right ploughshare). On the plow legs sit cross arms i °, i ^b , i ^c and i ^d , which carry the ploughshare. Clamping devices clamp the ploughshare firmly on these cross arms. The wheel axles are marked with 2 ", the edge strips of the properties G with R and the landmarks delimiting the property G with M !

In the plowing according to fig. 10 and 11 are the cross arms 1 "and ib rotatable in plow Grindelstrasse ι stored. In the cross-sectional square-shaped cross arms are clamped pivot lever 4, which accommodate the spindle nut 5 a threaded spindle 6 for adjusting the cutting depth of the plow shares. Furthermore, the pivot levers 4 form the axial stops which prevent the cross-arms i ^a and i ^ft, which are pivotably mounted in the plow shaft and connected to one another, from moving in the axial direction.

How it works: When plowing, you leave the ploughshare between the The tractor's wheel tracks run (Fig. 2 and 3). If the plow approaches the border strip of the Property, then you move the ploughshare so far outwards that it is outside the lane is working. In the subject of Fig. 4, this was done in such a way that the plow leg 1 on the Wheel axis 2 ° shifted to the right and the ploughshare 3 removed from the cross arm i "and on the Transverse arm i * was placed.

If one wants to according to Fig. 5 Pull successively furrow next groove, then one uses a plow with a left and a right plowshare (3 ¹ × or 2> ^R) ■ On the way usually the ploughshare 3 ^L working (Fig. 6) and on the return trip the ploughshare 3 ^R , which must therefore be swiveled up or down accordingly after each trip. On the other hand, when plowing the verge, the ploughshare should be converted as shown in Figs. 8 and 9. The ploughshare 3 ^ is clamped in this case on the cross arm i ^a , the ploughshare 3 ^L on the cross arm 1 ^d because the edge strips are turned inwards.

The device according to Figs. 10 and 11 represents an embodiment of the device described. With this device, the principle of action is previously known, the cross arms are against Sideways hiking secured. The transverse levers 4 fastened thereon carry the spindle nut 5. A Turning the threaded spindle 6 causes the ploughshare 3 to pivot about the transverse arm axis, as a result of which the coulter angle and thus also the cutting depth is changed.
