DE564086C - Planting machine in which the furrow coulter is arranged under a plate that slides on the ground - Google Patents

Description

In the case of the planting machines, the young plants are usually inserted in the So that a furrow is drawn by a flock and the plant is deposited in this furrow and the furrow is then filled with earth again by covering it. This way of working has the disadvantage that the plants often fall over, are spilled or lack not rooting enough firm root

ίο can grasp and enter.

The invention is intended to remedy this disadvantage, namely in that the Do not close the furrow by filling it with soil, but by pressing it from the side the furrow takes place. For this purpose are under a plate that slides on the floor Lateral oblique knives arranged behind the furrow coulter, the laterally the Cut a furrow in the soil and close the furrow. The plants are on Wrapped in this way at the side, cannot be covered with earth and can be in that take root more easily in compacted soil.

The pinch knives are expediently attached under the same sliding plate, under which the furrow coulter is located in a known manner for slitting the soil. In order to make it easier to penetrate the ground, can also be in front of the Zudrückmesser cutting disks be arranged, as they are for this purpose with flocks etc. are widely used.

The drawings illustrate an embodiment of the invention. "It shows Fig. 1 Section 1-1 through Fig. 3, Fig. 2 Section 2-2 through Fig. 3,

The support of the planting machine is the plate a, which is slightly bent up at the front.

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 surface of the earth is leveled, and at the same time it is prevented that the cut earth is pushed out upwards or falls into the plant furrow and covers the heart leaf of the young plant with earth.

The front upwardly curved plate a has a cutout f running from the center backwards, at the tip of which a two-winged, height-adjustable exchangeable knife b for cutting open the ground is attached to the bottom. The knife b diverges backwards and into two parallel guide wings, so that

the young plants can be inserted there easily and conveniently by hand. Behind or partly next to this knife b there is a knife c according to the invention on one side or on each side, which has the purpose of pressing the plant furrow from the side towards the entire height again, thereby at the same time the plants in To pack the earth appropriately _ and to give them a hold '. With these knives c , the outer wings lie in the longitudinal direction of the plate, while the inner wings can be adjusted for a larger or smaller angle by means of handle k and eccentric i to be able to press less firmly. The height of the knives c are also adjustable and interchangeable. The action of these knives occurs just behind the wings of the furrow opener b . At the same moment in which the soil pressed by the last-mentioned knife grips the plant, a certain amount of water is also supplied to the root '5, if necessary. In order to achieve this, a water container d is set up on the plate α at the front, from which a pipe or hose r leads to the rear end of the wing of the furrow knife and shortly before the end it has a self-closing taper by spring j. The tap handle q is simultaneously pushed away by the hand of the worker using the plant and the tap is opened for a short time.

The worker sits in the front of the chassis with his back against the water tank with his legs almost stretched out. So that the worker who looks backwards can devote himself entirely to the planting work and can insert the plants without difficulty so that they are always the same distance from one another, a wheel i is attached to the plate, which actuates a signaling device w through transmission ν , so that a signal sounds every time after the same distance.

Behind the knives c are straight, round, thin disks η , which are positioned in the direction of the plate α or slightly inclined, and can be easily rotated about their axis, which throw the furrow created by the knife c. Instead of these discs, a few inclined, rearward-facing tines, which rake the furrow, are sufficient in weed-free soil.

In order to prevent weeds etc. from building up in front of the knives, the blades of knives ' b and c are bevelled sharply backwards. In addition, a round, sharp disk knife m , which can be rotated about its axis I , is arranged shortly in front of each of these knives, 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.
