SNOW THROWER EXHAUST PIPE

The invention relates to a snow thrower outlet pipe consisting of two parallel plates, a plate connecting beam and a snow guide member between the plates connected to the plates by an axis allowing the guide member to turn the snow to the right or left, the guide member being powered by a hydraulic cylinder.

A previously known device is disclosed in publications FI 60049 and 890910. In these known devices, the blockage 10 is caused to open by stopping the rotation of the centrifugal blade and then opening the blocked point.

It is an object of the invention to provide an outlet pipe for a snow ligo which is not easily blocked and if it is blocked, the opening can be made hydraulically from the cab.

The device according to the invention provides a decisive improvement in the above-mentioned drawback. To achieve this, the device according to the invention is characterized by what is set forth in the characterizing part of claim 1. The main advantage of the invention can be considered that the blockage can be opened hydraulically from the cab, whereby it takes place quickly and safely.

In the following, the invention will be explained in detail with reference to the accompanying drawings.

Figure 1 shows a centrifugal snow removal torch according to the invention, as well as its location in the centrifuge.

Figure 2 shows the corresponding exhaust pipe in the position in which the snow flies to the left.

Figure 3 is a side view of the corresponding outlet pipe.

In Figures 1, 2 and 3, the snow removal tube is formed by two 30 parallel plates 1 and a beam 2 connecting the plates.

The snow guide member 3 between the plates is connected to the plates by a shaft 4 which allows the control member to pivot in the plane of the plates. The control member is powered by a hydraulic cylinder 5, one end of which is connected to the beam 2.

5 The guide member 3 is wider at the top, guiding the snow either to the right or to the left. In the same motion, the snow guide member removes any blockage of the pipe by swiping and pushing the blockage away from the open sides of the pipe. To this end, the plates 1 are not substantially wider 10 than the wide upper part of the control member 3 and the movement distance of its lower part, so that at least large areas are left in the outlet pipe from which the control member does not wipe the blockage.

It will be apparent to those skilled in the art that various embodiments of the invention may vary within the scope of the 15 claims set forth below.

Claims (1)

3 89091 CLAIMS A snow thrower discharge tube consisting of two parallel plates (1), a plate connecting beam (2) and a snow guide member (3) between the plates connected to the plates by 5 axles (4) allowing the guide to turn to the right or left of the guide member the hydraulic cylinder (5), one end of which is connected to the beam, characterized in that the snow guide member (3) is wide at its axial top and the width of the plates (1) in the direction of movement of the guide member (3) is not substantially greater than the width of the snow guide member (3) and the travel of the lower part in this direction, which ensures that the plates (1) are cleaned by swiping the snow guide member (3) if the tube becomes possibly blocked, which opens it by pushing the blockage 15 away from the open sides of the tube. 4 89091 Auxiliary parts for a vehicle, for example, with a parallel beam (1), for the left (2) with a beam for the bogie (3) with a bogie for the bogie with the axle (4), with a beam of 5 styrningsorganet för styrning av snön account höger ellan vänster, varvid styrningsorganet 1) the name and address of the management body of the company (3) stockas, vilket öppnar det genom att skjuta bort proppen genom de öppna sidorna. li
