Snow plow-course-making device

The invention relates to a snow plow-laying device for outdoor roads and also to ordinary roads, with which when plowing 5 trails are obtained next to the road.

Previous ski equipment is connected behind a tractor, snowmobile or snowplows. These are good in open terrain, but it is often necessary to have a normal walkway and trails on eg 10 outdoor roads.

Cross-country skiing with normal skiing is heavy among snow-lumps next to the roads. Another disadvantage is that the trails do not stay in good condition after snowfall and plowing.

The device according to the invention provides a small platform at the edge 20 of the plowing where there are tracks after each plowing which is characteristic of the device and which is set out in the first claim.

In the following, we consider the invention in the accompanying figure avu-1a: Figure 1 shows a front view of a snow plow laying device, cut at the laying device.

Figure 2 shows a snow plow pasture device from the side, cut at the outer ski in a low snow situation.

30 Figure 3 shows a snow plow pasture device from the side, cut at the outer ski in a snowy situation.

Figure 1 shows a snow plow (1) with an opening (2), at its lower part, behind it a vertical sealing plate (4) facing backwards in the direction of travel and a curved sealing plate (3) in a horizontal plane which is adjustable on the joint (6), up -down and located - - - ---- - "* ---- 4 ........._ .. .... ·,:. ··.. ··. **: 2 69334 at the top of the opening (2). The support arm (9) of the sealing plate (3) can be adjusted and locked in the required position.

Skis (5) are attached to the curved plate for the trails.

5 Figure 2 shows the snow (7) in front of the plow (1) and the compacted snow (Θ) as well as the track (10) behind the snow plow in the low snow situation.

In Fig. 3 the snow layer (8) is thicker than in Fig. 2, i.e. the curved plate (3) is adjusted for heavy snow.

10 It is also possible to add previously known solutions to the snow plow-laying device, such as devices to prevent the drainage of the snow barrier, e.g. the Swedish Bremmer oat, v. 1, 1939, 94-836.
