For providing high seeding output and more flexible adaptation to a practical use the material can be transferred from a hopper of the transport capacity into the storage container the material can be reloaded from the hopper of the transport capacity into the sowing machine hopper by means of a transfer device using either the transport facility coupled to the coupling means during operational position or from the disconnected transport capacity in the non-operational position.

Description

The invention relates to a seeder according to the restrictive part of claim 1 of the claims.

A seeder of this type is known, for example, from I8 2008/0314302 A1. This planter contains a central feed hopper, from which the material to be introduced is fed through the metering device and the attached feed lines to the planter coulters. In order to achieve high performance per unit area, a towed transport capacity is located on the drawbar hitch located on the drill carrier frame. With the help of the drawbar and the corresponding coupling device, this transport container is permanently attached and towed during the entire application process. The transport tank contains a material hopper, from which the material can be reloaded into the seeder hopper by means of a transfer device made in the form of a transporting device.

In some cases, during application, it is sometimes advisable not to tow the transport capacity with the drill permanently. Disconnection is not possible and is not provided.

From EP 0584463 B1, another planter is known which contains a feed hopper. If necessary, the feed bunker can be replenished with interruption of work with the help of a transport container standing on the edge of the field, where it is permanently located, by means of a reloading device located on the filling trailer and made in the form of a screw conveyor. Because of this, during the application process, it is not necessary to tow the transport container to replenish the seed drill hopper. However, in this case, it is not possible to tow the transport container behind the seed drill during the application process and, if necessary, load the material from the storage tank into the seed tank during the application process.

The basis of the invention is the task to perform the above-described planter, which has a high sowing capacity, with the possibility of more flexible adaptation to the conditions of use.

According to the invention, this problem is solved by realizing the possibility of reloading material from the hopper of the transport container to the seed hopper of the drill using a loading device of choice, or from the transport container connected to the towing hitch during the application process, or from the disconnected transport container with work interruption . In addition, thanks to these activities, high productivity of ordinary seeding is possible. Additionally, a high degree of flexibility is ensured thanks to the possibility of choosing either joint towing of the transport tank or only planting material using a seeder without an attached transport tank, for example, on soft soil. In this case, the replenishment of the material is carried out with the interruption of work at the edge of the field.

A simple implementation of the transfer device is realized due to the fact that it is made in the form of at least one screw conveyor.

It is also possible to provide several screw conveyors for each material, if the transport capacity contains several bunkers for accommodating various materials.

In order to have the possibility of favorable material overload by means of a reloading device, even when moving in a curve, it is provided that the reloading device is arranged to rotate around an axis at least approximately vertical, and to be able to move to different positions. This pivoting arrangement of the transfer device is also advantageous in order to be able to precisely match the transfer device with the seed drill of the planter in the interrupted method.

In order to be able to ensure optimal following of the transport capacity behind the seeder of small turning radii, as well as the compact arrangement of the seeder and transport capacity when the refueling trailer is attached, it is provided that the traction coupling device is located on the carrier frame with the possibility of movement. Thanks to this arrangement, the trailer coupling can be arranged in accordance with the existing conditions of use. This arrangement of the trailer coupling with the possibility of movement can be realized in the simplest way by the fact that the trailer coupling is located on the carrier frame by means of a regulating device, preferably made in the form of a regulating system of levers, namely with the possibility of moving the connecting point for attaching the drawbar towards the direction of movement in the process of turning.

Further details of the invention are derived from the description of the embodiment and the drawings. They show:

FIG. 1 is a basic image of a seeder with an attached transport capacity in the side view;

FIG. 2 - a seeder with a transport capacity, but without an image of the net harrow and screw conveyors of the transport capacity, when driving in a straight line; and FIG. 3 is a depiction of a seeder with a transport capacity, similar to FIG. 2, when moving in a curve.

The seeder contains a bearing frame 1, on the front side 2 of which the drawbar 3 is located, and on the rear side 4 - a running gear containing driving wheels 5. On the supporting frame 1 in several transverse rows one after the other, at a distance from each other transversely to the direction movement and with clearances relative to each other, the coulters of the 6 planter are located. On the back side 4 not

- 1 016224 of the existing frame 1 above the driving wheels 5 there is a module 7 feed bins, consisting of two feed bins. Dosing and transporting devices (not shown) are attached to this module 7, which feed the seeds through the distributor head 8 to the elements for their introduction, designed as openers 6. A harrowing device 9 for covering the laid seeds with soil is located behind the openers 6 and the running wheels 5.

From the rear side 4 of the carrier frame 1 of the planter there is a drawbar coupling 10 for attaching the transport container 11.

Transport container 11 includes a drawbar 12, designed to be attached to the drawbar device 10 with the ability to detach. In addition, the transport container 11 has a chassis that contains the wheels 13 and at least one material hopper 14 with an attached reloading device made in this case in the form of a screw conveyor 15. With the help of a screw conveyor 15, the material in the corresponding hopper 14 transport container 11, can be reloaded into the corresponding feed hopper of the module 7. The screw conveyors 15 are rotatable by means of a turning device around an axis at least as clearly vertical, and can be moved to different positions (not shown).

Due to the accession of the transport container 11 with the possibility of disconnecting to the towing device 10, the planter can optionally overload the material during the application process using a screw conveyor 15 from the transport container 11 connected to the drawbar hitch, as shown in the exemplary embodiment, from the bunker 14 of the transport capacity 11 into the seed bunker 7 of the planter.

If, under the conditions of use, it is rational for the transport container 11 not to be towed by the seed drill during the application process over the field to be treated, the transport container 11 may be disconnected from the trailer coupling 10 and left at the right place at the edge of the field. After that, the material can be reloaded from the transport container 11 into the feed bunker 7 of the drill with the help of a reloading device 15 with work interruption, when the seed drill is in the overload position relative to the transport capacity 11 and the reloading device 15. Thus, the material can be reloaded from the transport bunker 14 capacity 11 in the corresponding feed bunker 7 seeders with the help of the transfer device, made in the form of a screw conveyor 15, optionally, or from the transport capacity 11 connected to the rod ovo hitch 10 at the time of introduction of the process or of the disconnected transport capacity to interrupt the work. This ensures high productivity of ordinary seeding with a high degree of flexibility. Thus, the additional bunker 14 can be towed by the seed drill during the application process of choice. It is also possible a single ordinary sowing on soft soils without co-towing additional capacity 14 and, thus, with less pulling force.

As specifically shown in FIG. 2 and 3, the trailer hitch 10 is equipped with a movable connecting position 16 for connecting the connecting position 17 of the towing bar 12. For this, the traction coupling device is equipped with a control system 18 of the levers, so that the connecting position 16, 17 for attaching the drawbar 12 can be translated in the process of turning towards the direction of movement, in order thus to provide the possibility of a narrow rotational maneuver with a compact connection while driving in a straight line. The control system 18 of the levers of the towing hitch 10 should be fixed by means of a control device (not shown), to which, for example, a hydraulic cylinder can be attached, in the position shown in FIG. 1 and 2, and in the process of turning it is transferred to the position shown in FIG. 3
