Machine for spreading material.

The invention relates to a machine for discharging material, which is provided with discharge organs and with the aid a movement mechanism in a wide working position and a narrow transport position pivotable side boom has, on which track markers in a work as well as a transport position are movably arranged. The invention is based on the object, both the side arm and the track markers from the operator's station the machine or from the driver's seat of a tractor pulling the machine in the working and transport position to be able to move. If the track markers are in the form of track markers, the The alternate engagement and disengagement of the track markers required when the machine is in use can be carried out.

According to the DT-OS 193424? is already a machine at the beginning described design known. This machine has the disadvantage that when lowering the side boom the The marker must be moved into the working position by hand by a second person. If not a second

Person is available, then the machine operator must interrupt the lowering process} get down from his operating position and the marker by hand Swivel on the side arm. After the lowering process has ended, the machine operator has to step down again required by his operating status in order to bring the markers into working position by hand. If this does not happen, then the fact that the downwardly hanging track markers hit the ground, Before the side arms have reached their working position, damage to the marker and side arms unavoidable.

With the exclusion of the above-mentioned notice » times the object is achieved according to the invention in that the lane markers are also connected to a Movement mechanism connected for engagement in the working position and disengagement in the transport position are. A significant simplification is achieved in that the movement mechanism for the bout markers is coupled to the movement mechanism for the side boom. As a result of this measure is just a drivable moving mechanism for moving both the boom and the Track markers required in or out of the working position.

In an advantageous embodiment of the invention are a stop is provided within the connection between the movement mechanisms for the track markers.

409817/0064

Depending on the design of the movement mechanism, not only can the track markers with the side arms be moved into the working or transport position, but an additional upstream or downstream movement of the track marker is possible. This ie.t the event important in the row marker should touch on a trail in the ground to protect the right ATastandes work for the next train _s since then first the movement of the side arm and the row marker is carried out in the working position and also then the row marker alternately in need to lower the floor.

Alternatively, a "simplification" can also be achieved in an embodiment according to the invention in that the track markers are connected to parts of the machine via additional connecting elements. However, this measure allows without a drivable mechanism for the track markers and without the need to connect the movement mechanism for the side outriggers with the track markers, a simultaneous engagement and disengagement of the track markers into or out of the working position when the side arms are moved into the working position or into the transport position _e

In a preferred embodiment of the invention, in which the track markers can be lowered to the ground Bout markers are formed, the bout markers are after the Btfinding over additional connecting elements

409817 / Ö064

connected to a switching device for alternating lowering and raising of the track markers. This also enables the track marker to be lowered alternately during operation in the working position on the floor and lifting from the floor possible.

The invention also provides that the movement mechanism for the side boom is a hydraulic system contains that on both sides. one arm is connected to a toggle lever, which can be pivoted are arranged on the side arms and the other arm via a connecting element with one each These measures are particularly effective with machines, their side arms and Track markers are particularly large or have additional functional parts such as seed coulters with brackets, seed harrows etc., for easy and convenient handling. In connection with the measure, after which the track markers via additional actuating elements with a switching device to reciprocate Lowering and raising the lane markers is a very simple design of the hydraulic system possible. This then only needs to consist of a cylinder that is attached to a side arm on one side, arranged on the other side via the piston rod of the hydraulic piston on the other side arm without the need for an additional fastening or guide mechanism.
