Description

In the case of the planting machines, the young plants are usually inserted in the Way that the plant is deposited in the plant furrow or holes and the furrow through Cover is filled with soil or closed by pressure rollers. This procedure has the disadvantage that the plants multiply fall over, be spilled or fail to take root due to a lack of firm attachment can. The pressure rollers running over the floor are fixed to a frame in such a way that the pressure can also be if the rollers are at an angle, it acts more vertically. Also arise this way slightly detrimental compacted tracks, and the - plants are indented unevenly deep.

It is also already known that the plants are pressed against the surface by means of plate-like curved panes to effect, which are attached to revolving wheels and opposite to Rotate the direction of travel of the machine. The opposite working direction will but swept the earth with the plants.

The shortcomings mentioned can be eliminated by closing the furrow done by pressing on the side. In a known machine that works accordingly this is done by inclined fixed knives, which when moving forward their inclination push the earth sideways. With these knives, the pressure is partially effective forward, so that the roots are not firmly packed and the earth is also digged can be. -

To bring about a lateral pressing of the furrow, in which the pressure is immediate acts laterally on the plant furrow, and to prevent the soil from being carried away, side movable rotating knives are now arranged according to the invention, which penetrate the soil at the side of the furrow when moving forward and Carry out a transverse movement against the row of pavements. The side pressing can also be done by happen on one side; so that the opposite furrow wall is not pushed back it is supported.

The carrier of the planting machine is einRalj- men ¹ · where a forward slightly curved ■ on}; ' Plate α is attached. "'% Ά · β

The ground is cut open evenly at the set depth, whereby a controllable lever pressure is exerted from the associated chassis on the plate α and thus on the surface of the earth. Under this pressure, the earth's surface is leveled, crumbled, and at the same time it prevents the cut earth from being pushed upwards or from falling into the plant furrow.

The front upwardly curved plate α has a rearwardly extending cutout b, at the tip of which a height and thickness adjustable, replaceable furrow knife d , which ends in a box c, is attached, in which the plants are guided to the location intended for them will.

Behind this are circumferential knives e on each side, which penetrate the soil next to the plant when the machine is moved and execute a transverse movement against the row of plants and press the furrow along its entire height. To the side of this rotating knife, pressure wheels f are arranged, which guide the rotating knife laterally and thus cause the transverse movement. The wheel "which drives the knives e is dimensioned so that they have the same speed of rotation. A device h is arranged behind the knives, which closes the holes made by the knives and the rest of the plant furrow. In order to avoid damaging or pelting, etc., the plants already used, an upstanding protective plate q is arranged on the device h. The lateral packing device can also only be arranged on one side. So that: With the one-sided arrangement, the side of the plant furrow opposite the measuring -% rn is not pushed back, pressure rods v, "pressure wheels, sliding carriages or the like ).

In order to prevent root fibers, weeds, etc. from settling in front of the plant insert box c , the cutting edge of the furrow diameter d is bevelled sharply backwards. In addition, a round, sharp disc knife which can be rotated about its axis is arranged just in front of the furrow knife d , which cuts the weeds and thus clears the way. Anything that remains uncut is pressed down by the rolling disc wheel so that the main knife then slides over it.

Claims (3)

Patent claims: 1. Furrow closing device for planting machines, through which the plant furrow is laterally pressed, characterized by circumferential knife (e), the after penetrating the soil, make a transverse movement against the row of plants. 2. furrow closing device "according to claim i, characterized in that the knife (<?) arranged laterally movable and are guided to the side, for example by means of pressure rollers (/). 3. furrow closing device according to claim ι or 2, characterized in that the knife (s) are arranged only on one side of the row of plants and the plant furrow is supported on the other side. 1 sheet of drawings
