Abstract

1. A snow removal device (3) to be fitted on the front of a carrier vehicle (2), said snow removal device having a rotor to take up and eject the snow via an adjustable loading chimney (9) onto the loading area of an accompanying vehicle (1), characterised in that there is attached to the frame (4) of the device a push rod (13) which, at least for operating duty, extends in the forward direction beyond the snow removal device, so that a buffer (21) fitted onto the front end can be positioned, for its pushing operation, against the rear side of the accompanying vehicle (1).

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a snow blower that is mounted on the front side of a vehicle and driven.

[Prior Art] This snow blower has an impeller that rolls up snow and throws the snow through a rotatable loading slot and onto a trailing loading platform. Such snow removal machines consist of rotary snow removal machines or snow blowers or combination machines of this type. Particularly in the case of use in urban areas, for example when clearing snow against a border wall, it is required that the excavated snow be removed immediately. For this purpose, snow blowers run in parallel with a trailing type with a cargo platform, and the trailing type generally runs ahead of the snow blower in order to avoid interfering with traffic as much as possible.

In order to carry out the snow removal task mentioned above, skilled drivers are required not only for the vehicle carrying the vehicle but also for the accompanying vehicle. Both cities must be driven at the same speed so that the snow thrown from the loading nozzle reaches the intended dodging platform.

Since the transmissions in both cities are designed differently, i.e. the working speed of the vehicle is clearly below the minimum speed of the companion type, additional problems arise when coordinating the driving speeds. In the past, this problem could only be solved by the driver of the companion type constantly slipping the clutch, thereby significantly reducing its speed.

[Means for Solving the Problems] In order to remedy the drawbacks mentioned above, that is, to ensure coordination of running speeds in the simplest possible way, according to the invention, the push rod is pinned to the snow blower frame. The push rod is coupled to the front beyond the snow blower so that the push rod brings against the rear side of the follower type a shock absorber attached to the front end of the push rod for the propulsion drive of the follower type for at least power distribution purposes. It is suggested that something stands out.

Embodiments of this invention are described in claims 2 and below.

[Operation, Effect] The proposed solution: is extremely simple. Solution V, is
It is only assumed that the snow blower is equipped with a push rod, preferably of variable length and tiltable in a vertical plane, and that the trailing type is switched to neutral,
The auxiliary engine can be turned off. At least when removing snow from the boundary wall, the accompanying type and the vehicle equipped with it drive at a distance from each other in the longitudinal direction, and the accompanying type takes the lead closer to the center of the road, so the push rod is placed adjacent to the side of the snow remover closer to the center of the road to remove snow. It is reasonable to fix it to the machine.

In order not to impair the operation of the snow blower, i.e. to correctly maintain the necessary pressure on the road surface, press 1. It is reasonable that the rod is arranged so that it can be tilted from a horizontal position toward 7. The tilting angle is determined on the one hand by the distance between the vehicle and the companion model, and on the other hand by the height of the platform on the side of the companion model. In the upward position of the forest, an additional force component is generated that allows the snow blower to be pushed to the ground in a desirable manner.

The solution proposed on the basis of this invention is superior to the possible fixed connections of the vehicle and companion type. Due to traffic conditions, it is generally necessary to be able to operate in both cities independently of each other at any time. Furthermore, fixed connections have deficiencies in terms of maneuverability.

Otherwise, the driver would have to leave the vehicle to make or release the connection.

It is further provided within the scope of the invention that the push rod is provided with a hook at its front end, which hook engages in a ring provided on the rear side of the trailing mold or is simply hooked onto the carrier. There are possible alternatives. However, this alternative presupposes a very rigidly constructed loading platform.

[Example] Next, an example of the present invention will be described based on the drawings. The drawing shows a snow blower in the form of a so-called lateral snow blower 3 mounted on the front side of the vehicle between the rear end of the trailing type 1 and the front end of the vehicle 2. The snow blower is shown in a simplified manner in the drawings. The snow blower is mounted on the -1- of the machine frame 4, and the machine frame is connected to the heavy side plates 6 of the loading vehicle 2 by the machine side plate 5.

In the L of the casing 7 of the snow blower 3, there is a snow throwing tube 8 that can be tilted around the rotation axis of the impeller (not shown), and the snow throwing tube is also loaded. A plow blade 10 attached to the side surface of the impeller casing 7 removes snow from the impeller casing 7.
population. A pusher cup 13 is pin-coupled to a vertical frame portion 11 that projects upwardly of the machine frame 4 and is tiltable in a vertical plane around a horizontal @12. The tilting angle W of the press cup 13 is approximately 60 degrees, and in reality, the tilting position is preferably up to 30 degrees. For tilting the push rod 13, a hydraulic piston 14 is coupled to its underside, and this hydraulic piston is supported on the machine frame at a pivot point 15. In its initial position, the pusher 13 is placed on the horizontal plane 16 on the F-side crosspiece 17 of the vertical fork-shaped guide 18. The guide 18 consists of two side posts 19 that support the pusher cup 13 from both sides, and these side posts are joined at their -L ends by a horizontal bar 20 to increase the stability of the guide 18. Its detailed view is shown in the upper left corner of the IA plane.

The pusher J413 is configured to be extendable in a telescopic shape. A shock absorber 21 is fixed to its front end, and this shock absorber consists of a steel base plate 22 and a cap-shaped rubber pad 23. On the one hand, the rubber lining reduces damage on the side of the vehicle being pushed. On the other hand, it makes it possible to better adapt to the shape of the rear side of the loading platform and, moreover, acts as a crash absorber.

A pressure switch is embedded in the rubber pad, and this pressure switch operates a current circuit via a removable connection cable (not shown), which circuit is transmitted via an indicator in the driver's cab of the escort vehicle. It is also conceivable to indicate a break in the connection between the push rod and the trailer.
