Description

The invention relates to a wind protection device on centrifugal fertilizer spreaders, which accordingly the spread of the machine with in working position protruding beyond the machine width and after is provided rear pivotably arranged side arms. Devices of this type have the Purpose, on the one hand, to eliminate the influence of the wind on the spreading process from the outside, on the other hand to keep the dust generation when scattering powdery StreustO'ffe within acceptable limits.

In the case of centrifugal spreaders, wind protection devices are already known which move with both sides Provide side arms that protrude beyond the width of the machine and are foldable to the rear are. This foldable arrangement was made solely for the purpose of conversion these devices hit the narrowest possible transport position.

To swing the boom backwards while To prevent work, the extension arm is locked in the working position that has been swiveled out to the side necessary. This locking, however, has the disadvantage that the wind protection devices when bumping into posts, fences, trees, gate entrances or inevitable in practical use other obstacles are damaged. The invention overcomes this disadvantage in a simple manner by that between the foldable side arms and the device frame of the centrifugal spreader is arranged a spring which the jibs basically retract into the working position. For example to avoid too frequent clinking in closely-spaced orchards and tree nurseries or To adjust the wind protection device to narrower bed crops, the invention sees in further Design provides that the working position of the boom can be adjusted by ropes, chains or other connecting elements is set, each on the one hand on the rigid middle part of the device frame, on the other hand are attached to the folding outriggers.

The invention thus provides a significantly improved design of a wind protection device has been created in which any damage to both the device and the crops by bumping is avoided or the device can be adjusted to narrower bed crops can.

The invention is illustrated by way of example in the drawings. It shows

but with the side arms folded back in the transport position, also in the view from above.

The two side arms 1 of the draft shield device are pivotable about a pivot 2 each, both of which are mounted vertically on the device frame 4 of the centrifugal spreader provided with two centrifugal disks 6. They are each pulled into the working position by a spring 5, which is arranged on the one hand on the side arm 1, on the other hand on the device frame 4 or directly on the spreader.

The boom 1 can thus give way to the rear when it hits an obstacle and snaps afterwards Passing the obstacle back to its starting position.

In a further embodiment, the invention provides that the outer end position of the boom 1 through mutually adjustable ropes, chains or other connecting elements 3 is determined.

For transport, the booms 1 are simply folded back and carried over in a manner known per se the ropes, chains or other connecting elements 3 locked in the new position.

Claims (1)

Patent claims: . 1. Draft protection device on centrifugal fertilizer spreaders, which according to the spread of the machine with in working position across the machine width provided protruding and pivotable to the rear side arms is, characterized in that springs are arranged between the side arms and the device frame who seek to pull the boom into working position. 2. Draft protection device on centrifugal fertilizer spreaders according to claim 1, characterized 109 539/26 draws that the working position of the boom by ropes, chains or other connecting elements is set, on the one hand on the rear central part of the device frame, on the other hand to the pivotable booms are themselves attached, the length of these connecting elements being adjustable is.
