DE659252C - Furrow pulling machine with a furrow coulter that moves back and forth to the side - Google Patents

Description

The invention relates to furrow pullers, both of which have a coulter at the side performs a reciprocating motion. The movement takes place by one horizontal axis near the lower edge of the share. Downside to this A known arrangement is that the furrow walls are firmly pressed down to the furrow sole will. It has been shown in practice

10 that the growth of plants is essential is encouraged when loosened in the lower area of the furrow for the suction roots of the plants Floor is available. The furrow must therefore be made that it is smooth and firm in its steep walls and loosened soil in the depths having.

According to the invention, the mentioned deficiency is eliminated by the fact that the coulter In addition to the known movement, a horizontal axis can also move about an approximately vertical axis. Through this is created in the deepest point of the furrow by a kind of stirring movement of the share tip properly loosened soil, so that after the furrow has been entered the plants are given the opportunity to develop their suction roots to develop in loose soil. To adapt the machine to the various requirements the angular deflection of the rotary movement and the lateral deflection of the reciprocating movement can be adjusted.

A further improvement of Scharspitzenriihrbcwegung is still achieved in that the coulter is extended beyond its horizontal pivot axis out downwards, suitably such that ^r obliquely extending from back to front extends downwardly. -

In order to prevent the crowd from walking too quickly to and fro Energy is consumed, you can determine the number choose the back and forth movements so that the coulter when covering a distance equal to the coulter length about one Performs reciprocation. For this purpose, the number of strokes can be adjusted do.

A further reduction in the price is achieved by the fact that the crowd is going back and forth Movement only carries out brief periods of time, but in the meantime in one Rest position, expediently the middle one, remains. This creates a furrow that very much during the time of the standstill

is narrow and, due to the lack of solid walls, immediately closes again and therefore does not close needs to become. When ·. Pivoting movement of the coulter arise xii? ' certain intervals a kind of planting holes., ': "which have the advantages described above ,, .- will several furrow pulling devices '"' are provided on one machine, so it is necessary to that two adjacent furrow pulling devices to compensate for the inertia forces work in opposite directions, as is the case with agricultural machinery with side acting Tools is known. The opposite direction is of particular importance here, because it is only the smooth running of the machine that is caused by this that produces a smooth one and firm furrow guaranteed.

The invention is shown in the drawing in an exemplary embodiment, and on a two-furrow furrower.

Of the four wheels ^ ₁ , ^ _{2 of} the furrowing machine, the two rear ones, U ₁ , drive the crank disks O ₁ , b ₂ via a drive unit f, g, which move the coulters C ₁ , C ₂ in a sideways movement offset. In order to generate, in addition to the lateral movement of the coulter, a movement that rotates about an approximately vertical axis, the pivot ρ lying outside the plane of movement is connected to the guide of the coulter, as shown in Figure 3. The two parallel lugs form a guide for the handle of the furrow opener. So that the coulter can perform the rotary movement, it is articulated by means of a ball joint e. Figures 4 and 5 show the position of the coulter in the final lift position.

The size of the rotary movement can be changed by changing the distance A (Fig. 3). In the crank disks b _v b ₂ slots s are made, whereby the point of application of the linkage k can be shifted to the center point of the crank disk in order to be able to change the stroke.

The gear ratio /, g can be selected so that the coulter executes at least one to-and-fro movement when the machine is moving forwards the size of the coulter length. By replacing the gears, the number of strokes of the -. Shares in the travel unit is changed.
gj ₄ Fig. 6 and 7 show a cam disk for driving the linkage k, when used, the coulters only move at time intervals. The bolt h engages in the guide groove i and transmits the movements to the coulters via the linkage k. According to Figure 3, the coulter is extended by an amount V beyond the horizontal axis of rotation.

The drive shaft / for the crank disk b _L carries a chain wheel / "which drives the wheel on the shaft of the crank disk b _{2 by means of a chain".} The cranks b _i} b ₂ are set so quickly (Fig. 2) that they work in opposite directions.
