Description

The invention relates to planting machines. In the proposed planting machine, a device consisting of two discs is used, one of which is movable, on which the blades are fixed, which take on themselves - lumps with plants when passing near the descending branch of the conveyor. To clamp the blades to the soil pieces with plants, there are plates mounted pivotally on the disk and controlled in their motion relative to the blades by a guide slot in a fixed disk. The profile of the guide slit is designed so that after the root of the plate gets on the plant blade, the plant rotates and presses the plant to the blade, with further turning of the latter, approximately 180 °, they move to the side and the plant slides off from the scapula. - root down.

In the schematic drawing of FIG. 1 shows a vertical section of a landing gear; Fig, 2nd transverse horizontal section.

In the proposed planting machine, the usual accessory of which is a water tank with piping, a transporter for feeding seedlings, a coulter for opening the furrow and a ground crop, a characteristic feature is the planting apparatus constituting the main part of the whole device. Two rotating discs 7 (Fig. 2) and a fixed 10 fixed to the frame bar are mounted on the rotating shaft 6 from the axis of the running wheels of the machine. Diametrically intersecting blades Ji are bolted to the movable disk 7. The purpose of these blades is to take on seedlings brought to them by means of a transporter. In order that the seedlings during the rotation of the blades do not fall out and crumble at the highest and opposite points from the initial position (points H and P of Fig. 1), a metal plate kr is installed on the movable disk 7 (Fig. 1 and 2) at right angles to the auxiliary protrusion O (Fig. 1). The plate L, being pivotally mounted on the movable disk 7 by means of hinges 8 (Fig. 2), enters into it with its own axis, the outer end of which is fixed by the nut g, while the inner end is covered by the collar X (Fig. 2) extending from the rod, inserted into the guide slot 9 (Fig. 1 and 2) of the fixed disk 10, the entrance is the interaction of the crank 11 with its finger 11, which is stuck on the projecting end of the hinge 8 (Fig. 2). The effect of the cut in a fixed disk on the plate U,

it is calculated in such a way that, depending on the location of the axis of the plate of the cr at one or another point of the slit, the plate will either maintain a free open position, or hold the seedlings on the blade, or release this seedling. Thus, for example, while the transfer blade of the wheel is in position 1 (Fig. 1), the red plate is positioned vertically, and since the blade moves from right to left in the first quarter of the circle (from the initial position), it takes position 2 (Fig 1), the plate kr, since the axis of the rod entering the slot, is covered in its movements by the direction of this characteristic curved slot, changes its position and moves from a horizontal plane to an inclined, i.e., a lump of earth with seedlings. Changes in the planar position of the plate are determined by the peculiar structure of the slit 9, the passage of which in places of bending, the core of the plate will change its gender, cm 1 and 1 CH 2 (Fig. 1) in a fixed disk, which will change the position of the plate on the axis xv of the moving disk. From the drawing (Fig. 1) it can be seen that the position “b 1 of the axis of the rod of the plate kr on the movable disk and csn 1 of the axis of the same rod inserted into the slot of the fixed disk takes the initial position, and figures 2 and csn 2 show the position of the same parts according to moment 2 (fig. 1), i.e. a position in which the transfer blade l moves closer to the plate lr, which is what the seedlings adhere to. The retention state of the plate will be maintained all the way to the passage of the blade until the third quarter.

a circle, the entrance to which (moment 5 of fig, 1) the cr plate, subordinating to the regulating direction of the notch 9 in the fixed disk, will already move away from the transfer blade l, and, therefore, from the seedling, which it held. By the beginning of the fourth quarter of the circle (moment 6), the plate kr, departure from the lump of earth, will release the seedlings so much that, subject to the law of gravity, it will freely fall out into the furrow prepared for it, root down along with the enveloping seedling lump of earth. The cr plates on the rod axis x are set to the number of blades l, i.e., for example, four, and the effect of all these four fixing devices is exactly the same.

The subject of the patent.

A planting machine with adaptations for grabbing the latter mounted on a rotating wheel and a conveyor feeding plants to the planting apparatus, characterized in that the blades of the method consist of 7 blades fixed on the disc soil lumps with plants during the passage near the escaping (feeding) branch of the conveyor and intended for pressing the planting material to the blades of the cr plates installed pivotally on the disk 7, by means of hinges 8, to control of which there are plates relative movement of the blades. "serves as guide slots 9 of the fixed plate 10, incoming into engagement with the fingers 11 of cranks 12, keyed on the protruding ends maj) Ner 8.
