Description

Agricultural attachment

The invention relates to an agricultural implement / in particular a soil cultivating machine for multi-row crops such as a precision seeder or hoe, with one connected to the three-point hydraulic system agricultural tractor attachable machine carrier, with articulated on this, from a swiveled out, Machine side bars pivotable inwardly into a transport position in a substantially horizontal working position and with a swivel device, which is supported in an articulated manner on the machine carrier, each with a machine side bar includes associated pivot struts and arranged below the pivot struts power lift.

In a known device of this type, the power lifts each extend from the machine carrier in a standing position Arrangement to the pivot parallelograms provided here and engage with their lifting rods in each case in the Working position of the machine side haws on the upper swivel strut of a swivel parallelogram. to at one The lifting rods of the upright power lifts do not impair the ground clearance of the machine if the lifting path is sufficient attached to the end area of the swivel struts directly adjoining the machine carrier. Because of this The unfavorable angle arm conditions caused by the inward pivoting of the machine side bars are considerable Forces are required so that the device can be operated with strong and

The invention is based on the object of creating an agricultural attachment of the type specified in the preamble of claim 1. \ J ", in which the machine side bars can be easily and simply produced inexpensively without impairing the ground clearance or other spaces located in the area of the machine carrier, Swivel power lifts exposed to less wear during operation. The invention solves this problem with the features of the characterizing part of claim 1. With regard to essential refinements, reference is made to the subclaims.

Due to the space-saving arrangement of the power lifts underneath the machine side bars in the working position ^ The swivel struts can be used without impairing the ground clearance or otherwise, e.g. for machine carrier or Machine side beam superstructures required spaces ;, the respective Power lift can be provided with a lever arm favorable for the pivoting movement. The pivoting the machine side beam can be secured with relatively lightweight, inexpensive power lifts with low compressive forces be performed. The pivoting arrangement of the power lifts means that the legs are extended in the transport position Lifting rods removed from the dirt area of the tractor tires so that they do not wear out as a result adhering dirt particles are subject to. The position of the power lift is largely independent of the position and arrangement of pivot points of the swivel device or the

Speaking heavy, expensive hydraulic cylinder in-ϊ. units is to be provided. The power lift or hydraulic I

cylinders are in operation, increased wear on the moving parts by ^ .. adhering dirt particles. exposed because they extend in the dirt area of the tractor wheels even with extended lifting rods. The lifespan of the power lift is therefore limited.

Swivel struts, so that the arrangement of the cylinder with simple means to meet the respective space requirements, e.g. the tool groups to be set for setting ■ need spaces that can be customized.

Although it is known, on structural parts. of the machine carrier Provide power lift for swiveling machine side bars in the working position of the machine side bars run diagonally down from the superstructure to the swivel struts, but is required by the ■ "Space requirement in the area of the machine carrier of the available Standing space for the arrangement of e.g. fertilizer boxes is limited.

For a further explanation of the invention, reference is made to the following description and the drawing, in which an embodiment of the subject matter of the invention is illustrated in more detail. In the drawing show:
