DE1121871B - Arrangement of the guide bars on the engine block of a motorized single-axle front mower - Google Patents

Description

The invention relates to an arrangement of the guide bars on the engine block of a motorized one Single-axle front mower, with between a pivot pin of the engine block and a connecting ring of the stile foot a sleeve made of elastic material is provided, according to patent application M 28357 III / 45 c.

Proceeding from this, the invention solves the problem of the elastic mounting of the spar foot as required to convert into a rigid arrangement. According to the invention, the arrangement is characterized in that that the pivot pin and the connecting ring coupling elements are assigned which the spar fork rigidly connect imt to the engine block in certain pivoted positions.

This has the advantage that on the one hand when the z. B. two-axle tractors working with a front mower drives forward and the farmer walks behind on the stiles, the elastic connection works and keeps the mower from shaking the handlebars, on the other hand, if that Front mower is removed when the bars about a vertical axis z. B. pivoted by 180 ° and when the farmer walks in the opposite direction and z. B. plowing or on the country road drives or does a work in the vineyard that has a rigid arrangement.

For example, the coupling elements can consist of spur gear segments, e.g. B. in the Kind of having three coupling element pairs offset by 120 ° from one another. The sleeve can be put together with a guide cone on the engine block, preferably by means of a face gear, be secured against twisting.

The drawing shows an embodiment.

screwed tight. The connecting ring 3 α of the spar base 3 carrying the spars 3 b is pivotable about the vertical axis Z, but is prevented from doing so by the spur teeth Ib, 3 c or by the rubber cone sleeve 5 via the metal guide cone 6 when the nut 4 is screwed onto the screw 7 .

In the position according to Figure 1, the spar base 3 is rigidly coupled to the engine block 2 via the spur teeth 3 c, Ib. The two-wheel tractor drives in direction N on the road, with the farmer ζ. B. sits on a single-axle trailer and directs the train by means of the spars.

If the securing clip 8 is removed and the nut 4 loosened, then the spars with their symmetry vertical plane z. B. can be pivoted by 15 ° into the position R according to Figure 2. In this case, the farmer can work in the field after re-establishing and securing the screw 4, 7 with a rigid coupling of the parts Ib, 3 c in the field, for. B. plow, the two-wheel tractor driving in the direction N , but the farmer strides sideways to the lane of the wheels.

If the securing clip 8 is removed and the nut 4 is loosened, the spars 3 b with their vertical plane of symmetry can also, for. B. can be pivoted through 180 ° into position E according to Figure 2. In this case, after re-establishing and

Securing the screw connection 4, 7 of the connecting ring 3 a via coupling strips 3 d engaging in grooves 9 of the rubber cone sleeve 5 via the rubber cone sleeve 5 and via the guide cone 6 with the spar connection head 1, the guide cone 6 being elastically coupled by means of its end teeth 6 a in the end teeth Ib is secured against twisting and the coupling strips 6 b prevent the rubber cone sleeve 5 from turning. The coupling strips 6 b engage in grooves 10 in the sleeve 5. The two-wheel tractor is now driving in the direction of Af and can carry a front mower.

Figures 2 and 3 show that there are three coupling element pairs Ib, 3c for the rigid coupling, so that the support is statically determined (three-point support with the three points in a circle around the axis Z).

The cam 3e serves as a stop for the shift lever of the gear change gear of the two-wheel tractor to prevent the farmer from being able to engage a reverse gear when he steps in the M direction while mowing.

The invention can also be used when the screw 7 is a fixed part of the spar foot 3 is and protrudes into a bore of the spar connection head 1 as.

Claims (4)

PATENT CLAIMS: 1. Arrangement of the guide horn on the drive Averkblock of a motorized single-axle front mower, with a sleeve made of elastic material is provided between a pivot pin of the engine block and a connecting ring of the Hohnfußes, according to patent application M 28357 III / 45 c, characterized in that the pivot pin ( 7) and the connecting ring (3 a) coupling elements (Ib, 3 c) are assigned, which rigidly connect the spar fork in certain pivoting positions (5, R) to the engine block (2). 2.
