CLASS 4S: Agricultural tools.

'Patented in the German Empire by ig. June 1883.

The present invention relates to innovations in plowing and crushing equipment agricultural implements determined by the earth from the patent no. 9598 which became known Construction.

First and foremost, the present device should be trained appropriately the plow tree taken into consideration.

The plow tree is kept straight and mounted higher at the front than at the back, in order to facilitate the approach exert the required downward pressure on the coulter and plow.

For vertical adjustment of the front and rear end of the plow tree, as well as the up The rear wheel running on the land side is an adjusting mechanism that can be operated from the driver's seat arranged. The skiving plow is narrower than the main plow in order to be next to the furrow of the latter to be able to leave a strip lying, which the complete turning over of the plowed by the former Strip allows. Finally, the construction of the grinding wheel is such that it completely cuts through the strips turned over by the peeling coulter, as shown below Description emerges in more detail.

In the field device shown in perspective in FIG. 1, the semolina column C ^{1 of} the main share A ^{1 is} connected to the plow tree B by bracket D ¹ , the semolina column C ^{2 of} the peeling share A ² by bracket D ² .

The rear end of the plow tree B is guided in a loop J starting from the axis G , and the beam H, which is firmly connected to the axis G , lies parallel to the tree B.

The loop J on axis G allows the plow tree to move freely up and down by means of the angular adjusting lever K ₁ which the operator can adjust from the resilient seat L with the right hand on the adjusting bracket M ¹ , which is attached to the beam H.

The latching lever M ³ , the control rod of which is guided in a sleeve seated on K , is used to fix the lever on the adjusting bracket. Any lateral movement of the front end of the plow tree B is prevented by rods N ^x N ² , which are firmly connected to the plow tree B by means of the eyes OO 'and bolts inserted and held on the axis G in the fittings P ¹ P " ¹ .

The front end of the plow tree is carried by one arm of the angle lever R , which is rotatable about a bolt at R ' on the beam H. This lever can also be adjusted from the driver's seat and by means of it one can regulate or regulate the aisle depth of each coulter. Lift each coulter out of the ground for the purpose of turning and transporting the agricultural implements.

The rear wheel S is rotatable on the pin S ^{1 of} the angle lever .S ² , which swings around the bolt S ³ , which sits on the segment piece S * carried by the axis G. A suitable adjustment of the pin S ¹ and wheel S can be effected on the segment .S ^{5 by means of} the latching lever S ^s. The angle lever, S ² , is adjusted with the left hand from the driver's seat and enables axis G and seat L to be kept in a horizontal position and the coulters in an upright position.

So that the front share the plowed

It is made somewhat narrower than the rear main share, so that a narrow strip remains between the furrows of both shares, which serves as a connecting band for the plowed strip, and which lasts long enough for the latter to be completely turned over from the moldboard to have an effect. The mouldboard of the plowing plow is curved in such a way that it causes a half-turn of the plowed strip around the remaining one, the former being inserted into the previously drawn furrow (see Fig. 2, in which the plowing share A ² as well as the main share A ¹ in horizontal projection and their related cutting lines are shown dotted).

The soil crushing wheel T runs close to the furrow last drawn on the plowed field, its width should approximately correspond to the width of the furrow, and the distance between the two rings T ¹ T ^{2 should be} measured accordingly. The latter are connected to one another by cross rails U ¹ U "* U ^z ... , which are bent towards the wheel axis, so that the wheel has a fluted shape on its periphery; the outer edges of these rails are just like those of the When the wheel rolls forwards on the turned-over ground, the rails are pressed into the latter and the rim T ' cuts through the weeds. As a result of the curvature of the rails, the wheel rims can be pressed down to the furrow floor by the weight of the agricultural implements So the wheel rummaged through the strip of land turned over by the front blade A "'without being significantly lifted.

The wheel hub is composed of the central elongated part V and the side rims V ¹ V ² of larger diameter which are used to fasten the spokes W ¹ W ^2. The wedge-like teeth W ^z W ¹ arranged on the outer wheel rim are used for Aufreisen.und crushing of the tilled soil, their number, length and position depends on the nature of the soil to be worked. The mouldboard of the main plow is connected to a screen V ¹ , which holds back the earth introduced into the crushing wheel until it has been crushed enough to fall through the openings left on the periphery.

The Ackergeräth described strives to bezw in a straight line. to move in a direction which is determined by the previously drawn furrow, next to which the grinding wheel rolls. The plow tree is held in a straight forward direction by the beam H and the loop J preventing it from shifting sideways. For this reason one can dispense with the otherwise usual sole on one of the shares or on both and thereby reduce the weight and the friction.

The position of the peeling share could also be arranged as shown in FIG. 3. Here the peeling coulter is to the side and somewhat behind the main coulter, so that the same thus draws its furrow to the side of the latter. In this case, the peeling share A ² turns over the strip of soil immediately behind the main share A ^1. During the first pass on unploughed ground, it is advisable to let the plow share A ^{2 go} alone through the field, on the following pass the main share A ^{1 is} lowered into the furrow previously made by A ² , with the third gear the shredding wheel runs respectively on the furrow last drawn. on the last strip of land that was turned over, chop it up and cut up the weeds in the manner described.

An advantage of the arrangement shown in FIG. 3 is that the main coulter is arranged in the middle between the peeling coulter and the shredding wheel, resulting in a symmetrical distribution of the tensile resistance, the resultant of which is then fairly accurate lies in the middle of the farm implements.

Claims (2)

PATENT CLAIMS: For agricultural implements with main and peeling coulter and soil shredding wheel arranged one behind the other: 1. The mechanism for the independent vertical adjustment of the front and rear parts of the plow tree B, characterized by angle levers R and K and the rods N ¹ N ² and loop J which serve for lateral guidance of the plow tree; also the segment S ⁵ with the angle lever S ⁶ for vertical adjustment of the pin .S ^{1 of} the wheel 5. 2. The construction of the grinding wheel, characterized by an elongated hub, two rows of spokes down from the ends ■ the outer wheel rim T ² go out, and the two wheel rims T ¹ T ² with inwardly bent cross rails, for the purpose of cutting through the folded field along with the weeds and chopping them up; Furthermore, the combination of such a comminuting wheel with a screen Y formed as an extension of the moldboard of the latter, for the purpose of holding back the earth introduced into the wheel until it is sufficiently comminuted.
