Description

The invention relates to a device for handling straw, hay and the like of low specific gravity in agricultural holdings which possess the mechanical means for adapting it, in which the control of the functional part - the holding device and the ejector - is addressed in a new way

Handling devices and said materials are known which operate as follows: after insertion of the active part into the material, it is fixed by a retainer and its movement is controlled by a linear motor, which also means a linear motor. After moving the filled device above the designated location a and the material is released by the backward movement of the retainer and the device is emptied by ejecting the ejector, the movement of which is controlled by another rectilinear motor. This means that the equipment must be connected to two separate power circuits, which is not possible for some mechanization means because they have only one power circuit available.

This drawback removes the solution of controlling both functional movements by a single linear motor according to the invention, such that on the retainer to which the rectilinear motor is connected and on the ejector arm there is a carrier-stop system by which the ejector is moved. The return movement of the ejector is ensured by the return element.

The advantage of this solution is the use of a single control for both functions, the ability to connect to a single power circuit and reduce material costs in the manufacture and maintenance of the equipment.® ·

The attached drawing shows the handling device and operating the ejector retainer of the invention in the take-up position. Endpoints are marked with a dash. On the main beam 1 there is a rotatably fastened retainer 2 and an ejector arm with an ejector 4. The rectilinear motor 7 is rotatably connected to the retainer 2 and the main shaft 1 and the working medium is allowed to move the retainer 2 in the range of extreme poldhs. When moving from the pick-up position to the lower end position, the stop 6 formed on the ejector arm 3 and the carrier g attached to the retainer 2 are separated from each other. Thereby aa fixes the collected material and the ejector 4 is billed to the main beam 1 via the ejector arm 3 with the return element 8. When the retainer moves from the pick-up position to the upper end position, the retainer 2 acts via the carrier 5, the stop 6 and the ejector arm 3 onto the ejector 4 and also moves it to the end position. Thus, by continuously moving the retainer 2 to the upper limit position, the material is released and the device ea is emptied at the same time. The return movement of the ejector 4 when the retainer 2 is moved from the upper end position to the pick-up position is provided by the return element 8.

Claims (1)

OBJECT OF THE INVENTION Apparatus for handling and low density materials, characterized in that it comprises a retainer (2) pivotally connected to the main beam (1), further coupled to the main bearing (1) by a rectilinear motor (7) which ensures the functional movement of the retainer (2). in the range of extreme positions and at the same time the functional movement of the ejector (4) and the ejector arm (3) connected to the main beam (1) so that a carrier (5) is formed on the retainer (2); the formed stop (6) and the ejector arm (3) are connected to the main shoe (1) by the return element (8).
