Arrangement for connecting accessories to the side of the machine

The invention relates to an arrangement for connecting accessories, in particular accessories used in the construction and maintenance of roadside 5, to the side of a machine, which arrangement comprises at least one telescopic arm part and at least one arm articulated to the telescopic arm part. The machine can be, for example, a road roller, a bulldozer or some other similar device. The accessory may be any device used, for example, in the leveling of road ramps, in mowing, in cutting machines or in similar tasks. With the help of the arrangement, the roadside can be hand-operated from the roadway with a machine.

The design of road ramps in connection with their construction and lifting is usually carried out by the excavator's so-called

with a ramp bucket, leaving the excavator most of the time across the road, disrupting traffic and posing a high safety risk. Special machines have also been developed for the design of ramps, but they are expensive given the workload.

A mower with a rotating cutting blade mounted on an excavator boom is commonly used to cut a growing roadside.

Tractors equipped with a mowing device are commonly used to mow hay and other vegetation along roadsides. However, the disadvantage of using a tractor is, for example, that driving takes place on a slope in an inclined position, which makes the driver's working position awkward. Driving on a ramp can also cause harmful grooves on the 30 ramps. Obstacles along roadsides, such as handrails and the like, mean that not all areas can be mowed with this method.

For ramping ramps and plowing snow, devices have been developed that have been able to increase the lateral dimension of the Lana or plow 35. Such devices are disclosed in, for example, U.S. Patent Application No. 900233, SE Publications 213950 and 401541, and U.S. Patent Nos. 2,646,633, 3,061,956, 3,348,322 and 4,953,625.

FI patent application 900233 discloses a device 5 with which the wing of a snow plow is attached to the side of a vehicle.

SE patent publication 213950 discloses a device by means of which a road leveling and asphalt spreading vane is attached to the side of the vehicle at a distance from the vehicle.

10 SE publication 401541 discloses a lath device with which various inclined surfaces can be leveled and compacted.

U.S. Patent No. 2,646,633 discloses an extension of the lane blade of the tiehoya, the length, plowing angle and inclination of which can be radiated.

U.S. Patent 3,061,956 discloses a sheet attached to the back of a tie rod extending to the side of the tie rod, the lateral extent, plowing angle and inclination of which can be obtained.

U.S. Pat. No. 3,348,322 discloses an extension of the lane blade of a tie, which is most suitable for plowing.

The solutions presented above are characterized in that they are intended to increase the lateral dimension of the Lana or plow during plowing or plowing. The disadvantage of 25 in most is e.g. the fact that the oblique support bar or other support structures at the front or rear of the Lana prevent traffic signs, light poles and other similar obstacles from entering the bay, thereby dividing untreated areas into the bay, which must be dealt with separately by another device. A common disadvantage of all the above-mentioned devices is that the railings and other similar long structures form a force majeure obstacle to the treatment of the area behind the railing. In addition, the above solutions are characterized by the fact that each of them has been developed for only 35 types of work, including the price of plowing and plowing.

The object of the invention is to provide an arrangement by means of which many different accessories can be fitted to the working machine with which the areas on the side of the road can be handled. Examples of accessories include lanate-5, mower, blade cutter, etc. Em. with the aid of accessories, the use of work machines, such as road surfaces, is increased during the summer, when their use is otherwise reduced. On the other hand, it should be noted that the machines currently used in said tasks, such as excavators for designing ramps 10 and cutting machines, as well as agricultural tractors for mowing ramps are freed up for their primary tasks, which are also mainly in the summer. In addition, the invention makes efficient use of the versatile control devices already available in work machines, as well as the disadvantages of the previously known solutions. Em. the facts are achieved by means of an arrangement according to the invention, characterized in that the first telescopic part of the telescopic arm part is fixed to the lan device of the machine substantially parallel to the lan blade.

The advantage of the arrangement according to the invention is e.g. the fact that, for example, the areas behind traffic signs, lighting poles and similar structures can be treated in their entirety by an accessory connected to the arm structure. Em. this is due to the fact that the first teles-25 copy part is directly attached to the rear surface of the machine's lan blade, parallel to the lan blade i without other interfering support structures. The area behind the railings and other similar structures can also be treated in the height and slope adjuster of the machine's implement as well as in the arm structure adjuster. It is easy to bypass traffic signs, light poles and other similar obstacles, as the arrangement and the accompanying accessory are completely inside the side line of the machine. The arrangement according to the invention, despite its simple structure, is versatile and provides roadside, bulldozers.

and other similar machines. Above all, the invention helps to reduce the construction and maintenance costs of road ramps as well as to reduce the inconvenience caused to traffic by the above-mentioned others and the risk of 5 kiM.

The invention will be explained in more detail in the following by means of a preferred embodiment shown in the accompanying drawing, in which Fig. 1 shows the arrangement according to the invention in a cross-sectional view of the area behind the handrail 15 is being treated, and Fig. 3 shows the embodiment according to Figs. 1 and 2 in a situation where the arrangement is in the transport position.

In the application example according to Figures 1-3, the first telescopic part 2a of the telescopic arm part of the arrangement is fixed substantially parallel to the lan blade of the lane blade 1 of the road surface lane device. A second telescopic part 2b is slidably fitted to the first telescopic part 2a. The telescopic arm part can then be moved la-; 25 with the help of the lanaterå's adjusting devices. At the outermost end of the second telescopic part 2b, a hinge part 3 is arranged to allow movement about a substantially horizontal and transverse axis with respect to the telescopic arm part 2a, 2b. A cylinder of the hydraulic cylinder 4 is fixed to the first telescopic part 2a. The end of the arm part of the hydraulic cylinder 4 is in turn fixed to the articulation part 3. By means of the hydraulic cylinder 4, the second telescopic part 2b can be moved between its outer positions shown in Figures 1 and 3.

35 By means of the articulation part 3, the second telescopic part 2b has

Attached to the outermost end of the arm 5 is an articulation means 8 enabling a rotational movement about an axis substantially tangential to the tangential movement of the arm 5, which may be, for example, an articulation joint. A hydraulic cylinder 7 is attached to the articulation part 3 and to the arm 5, by means of which the arm 5 can be adjusted between the articular positions shown in Figures 2 and 3.

A pivot shaft 8a is arranged in the articulation means 8, on the upper end of which the lugs for the rotating cylinders 10 9, 11 are arranged, and on the lower end a joint 8b. A fastening part 10 is arranged on the joint 8b, on the lower surface of which the tool or accessory required in each case is fastened, in the example of the figures a disc mower 12.

The inclination of the accessory 12 can be adjusted by means of a fitting cylinder 11 fitted between the lugs 8c and the fastening part 10. By means of a pick-up cylinder 9 arranged between the lugs 8d attached to the head shaft 8a and the lugs 5a attached to the arm 5, the angle of attack of the accessory 12 with respect to the direction of travel is determined. The structure of the joint 8b 20 is such that it allows the accessory to be rotated about a substantially horizontal axis, whereby the inclination of the accessory 12 is reduced. Ko. the fact is clear from the figures.

The embodiment of the invention shown in the figures is characterized by a large lateral dimension and xnon-like reach possibilities, which are further increased by the ornate reach possibilities of the machine Lana.

The application example shown in the figures is in no way intended to limit the invention, but the invention 30 can be modified completely freely within the scope of the claims. It is clear that the embodiment according to the invention or its details do not necessarily have to be exactly as shown in the figures, but other solutions are possible. For example, the telescopic arm part may have several steps than shown in Figs. 6 92343, thus giving the arrangement an even greater dimension. Correspondingly, the arm can also be a telescopically extendable device, etc. In addition to the road clearance, the arrangement can also be adapted to other work machines, for example trucks, agricultural tractors, bulldozers and other similar equipment. An accessory or tool that can be attached to the arrangement can also be any device suitable for the job in question, as noted above.
