Description

TECHNICAL FIELD The present invention relates to a tool in accordance with the claims. felling of snow, ice or similar masses from a surface. The side parts show the lower edges that can be applied to the substrate, as well as portions that receive and remove the felled masses. By means of pivoting means, each side part is allowed to pivot about a guide line perpendicular to the longitudinal direction of the main part.

Known buckets of this kind have the disadvantage that they are of limited use in scraping masses from surfaces inclined relative to the horizontal plane or substrates to be assigned a different inclination, for example in cases where it is desired to give the substrate as the main part of the tool a definite inclination to the horizontal plane. the slope of adjacent side surfaces. This can involve scraping masses from a sloping ditch or collecting material such as soil or snow from sloping walkways and carriageways, for example the area that forms the central carriageway boundary at a motorway where level differences can also occur in the surface being scraped and connected. parties such as sidewalks. There is thus a desire to be able to more efficiently scrape and fell masses from substrates which have separate surfaces which slope in relation to each other or in cases where it is desired to give surfaces of a substrate different slopes both relative to each other and towards the horizontal plane.

Via the Swedish patent specification SE536224 is a variant of a bucket, multiscope, which includes side parts, wings, which quickly compensate for oj substances and inclination variations that occur in the substrate. The construction according to the patent specification differs in substantial extent from the construction in accordance with the present patent application. A problem with this construction is that the side parts, the wings, can get stuck in certain positions. A further problem is that the construction only allows a limited width of the side wing.

The construction has a fixed center of rotation between the parts of the wing.

Patent specification SE525295 describes a vehicle-borne scraper implement. The scraper implement according to the patent specification includes side parts, wings, which compensate for irregularities and inclination variations that occur in the substrate. The construction according to the patent specification differs substantially from the construction in accordance with the present patent application. A problem with this construction is that the side parts, the wings can get stuck in certain positions. A further problem is that the construction only allows a limited width of the side wing.

The construction has a fixed center of rotation, Buckets with integrated scraper function are already known. For example, the marketing company YPV such a construction. There are problems with existing constructions of the scraper device which are integrated in a bucket. These can only scrape a limited part of the substrate to be scraped. The construction of the bucket further means that the entire width of the base is not scraped. The marketed bucket lacks wings. Furthermore, the object of the present invention is to eliminate or substantially reduce at least one of the previously mentioned, or any of the following description mentioned, the problems with existing types of scraper devices. The object is solved with a scraping device in accordance with the claims.

Detailed Description of the Invention With reference to the figures, an implement 1 in accordance with the present invention will be described in more detail. In the exemplary embodiment, the tool 1 comprises at least bucket 2. The shape of bucket 2 can vary within the scope of protection. An exemplary bucket 2 is shown in the figures which is not limiting of the inventive concept.

In the exemplary embodiment, the bucket 2 is formed with at least one material receiving space 3 which is delimited by a main part 4 consisting of at least one bottom part 5, at least one rear part 6 and a pair of adjoining side pieces 7 on the short sides of the implement. to a vehicle's tool holder. The side pieces 7 are preferably placed perpendicular to the front edge of the bucket. In alternative embodiments, the chancid pieces may be located at an angle other than perpendicular to the leading edge of the bucket.

To at least one of the side pieces 7 of the bucket, at least one side part 9, like a wing, flap or the like, is pivotally arranged. In an exemplary embodiment, the respective side piece 7 comprises at least one side part 9. For efficient felling of snow, ice, soil or similar masses from a substrate, both the main part 3 and the side parts 9 are provided at their lower edges with a cutting insert 10, planer steel or the like . In alternative embodiments, the side members may be without inserts 10, or the like. Each side part 9 is hinged 11 articulated to the leading edge of the side piece 7 side piece 7 pivoting the side part 9 about a hinge axis line 12 which is perpendicular to the longitudinal direction of the main part or in this case more precisely the width of the bucket. The side parts 9 are pivotable within a horizontal plane which can essentially be regarded as parallel to the ground. The pivoting of each such side part 9 within the horizontal plane takes place by the action of at least one hydraulically active actuator 13 which in this case consists of a hydraulic power cylinder (hydraulic cylinder) 14 is articulated between at least a first bracket 15 on the outside of the side piece 7 of the main part 3 and a bracket 16 on the back of the side part 9. The power cylinder is connected to the respective bracket with at least one pin 17, connecting part or the like. Note that Figures 1A and 1B are schematic and do not show the construction in detail.

With reference to Figures 2A and 4, it can be seen that the side part 9 (the wing) comprises at least one fixed part 18, first part, mounting part or the like, which is rotatably connected to the side piece via a hinge. The respective fixed part 18 is pivotally connected to one of the side pieces 7 of the bucket. The fixed part 18, the mounting part, is pivotally connected to the side piece 7. The fixed part 18, the mounting part, is connected to the side piece 7 of the bucket via the hinges at least one connecting part 19. In alternative embodiments, the bucket may lack a connecting part 19. The connecting part 19 may form a part of the side piece 7 or consist of a part connectable to the side piece 7. The connection of the connecting part to the side piece 7 can take place by welding, during the manufacture of the bucket or after the bucket has been manufactured and started to be used. In alternative embodiments, the connecting part can be screwed into the side piece 7 in connection with the manufacture or after the manufacture and the bucket has started to be used.

The side part 9 (the wing) further comprises at least one movable part 20, movable wing part, movable part or the like which is movably connected to the fixed part 18. The fixed part 18 and the movable part 20 are held together by at least one cohesive device 21 which comprises at least a first cohesive means 22A and at least one second cohesive means 22B.

In the exemplary embodiment, the side members include at least a third holding member 22C. The third cohesive member in the embodiment consists of at least a profile such as an angular profile or the like which is connected to the movable part in its free edge (with the fixed part between the third cohesive member and the movable part).

The movable part 20 of each side part 9 is spring-biased in the direction of the ground by the action of at least one first spring device 23. The movement of the movable part 20 towards the ground is limited by a stop member 25 serving as abutment 24 which ensures that the movable part 20 of the side parts 9 and the lower edge portions or cuts of the main part (in the bucket) are level or in line with each other when the side parts 9 are in unaffected rest position. To form abutments, said stop means 25 has been formed as a longitudinal upper bent edge portion 26.

The spring bias of the movable member 20 relative to the fixed member 18 is further achieved in that the movable member 20 further comprises at least a first bracket 27 for at least a first spring member 28 and at least a second bracket 29 for at least a second spring member 30. The fixed member 18 further comprises a bracket 31 for at least one first resilient member 28 and at least one second bracket 32 for a second resilient member 30. The first resilient member 28 is connected to the first bracket 27 in the blade 20 and the first bracket 32 in the fixed part 18. The second resilient member 30 is connected to the second bracket 29 in the movable part 20 and the second bracket 32 in the fixed part 18. The resilient members 28 and 30 cause the movable member 20 to return to the original position (when the lower edge of the movable member does not abut a base). The cohesive means 22A and 22B in the exemplary embodiment are constituted by stop means. In the exemplary embodiment, the stop means consist of plates. The plates are connected to the first guide means 35, or another part of the side part 9 suitable for the purpose (so that the fixed part and the movable part are held together).

The movable part 20 is slidably and movably supported by the fixed part 18 and the said parts are movably arranged up and down parallel or substantially parallel in relation to the guide line 12 by means of active holding and guide means.

The mutual movement between the side piece 7 and the mounting part 18 is controlled by at least one first holding and guiding device 33. In the exemplary embodiment, the mutual movement between the moving part and the fixed part 18 is controlled by at least a first holding and guiding device 33 and at least a second direction. and control device 34. Respective holding and control devices 33 and 34 comprise at least one first control means 35 and at least one second control means 36. The first guide member 33 consists of a variant of at least one plate 37, block or the like, and the second guide member 36 consists of a groove 38, hole, opening, recess or the like. The groove 38 is preferably directed in the vertical direction. The groove 38 in the eXemplifying embodiment has a rectangular shape with rounded corners. In alternative embodiments, another shape suitable for the purpose may be traced. The plate 37 is movably arranged relative to the groove 38. The plate 37 in the exemplified embodiment has a substantially rectangular shape but with curved surfaces (convexa) on their long sides. The width of the plate 37 is less than the width of the groove. In alternative embodiments, the plate 37 may be of a shape other than substantially rectangular. It is thus conceivable that the plate 37 has a square, oval or other shape suitable for the purpose.

The movable member 20 and the fixed member 18 are held together by at least one first cohesive member 22A and at least one second cohesive member 22B. The first cohesive means is connected to the first control means in the first control and holding device and the second cohesive means is connected to the first control means 35 in the second control and holding device. The cohesive means 22A and 22B in the exemplary embodiment are constituted by stop means which prevent the movable part 20 from being released from the fixed part 18. In the exemplary embodiment the stop means are constituted by plates. The tiles have a larger dimension than the dimensions of the grooves.

Depending on the difference between the width of the grooves 38 and the width of the plate, different degrees of mutual movement between the blade 20 and the mounting part 18, such as rotation, between the mounting part 18 and the blade 20 can be achieved.

The wing structure comprises at least one member 39 which prevents mutual locking of the intermediate parts. In the exemplary embodiment, the member consists of at least one round bar or other construction suitable for the purpose.

In the exemplary embodiment, the construction also includes scraper plate 40 or the like which limits the occurrence of a smaller string of snow or ice when scraping with the implement.

The present construction has a surface center of rotation of the movable part of the wing relative to the fixed part of the wing. The fl rotating center of the surface achieves improved mobility towards the ground.

Referring to Figures 3A to 3F, the relative mobility between the respective side portion 9, wing, constituent fixed portion 18 (first portion) and its movable portion (second portion) 20 is shown. The side portion 9, the wing, on the other side of the bucket 2, is mirror to the construction shown in the figures. Figure 3A shows mutual positions between the parts 18 and 20, which corresponds to the vertically highest position of the movable part 20 relative to the fixed part 18. The vertically lowest relative position of the movable part 20 is reached when the upper edge of the movable part 20 abuts the upper part of the fixed part 18. The spring bias causes the movable part 20 to strive to abut against the fixed part 18. The upper part of the plate abuts against the upper edge of the groove.

In Figures 3B, the movable part 20 is rotated according to the angle V relative to the fixed part 18. The inner part of the insert 10 of the movable part 18, in the direction of the bucket, the insert 10 is turned down to a lower vertical position relative to the fixed part and the bucket. The inner corner of the upper edge, in the direction of the bucket, on the fixed part 18 abuts against the angled part of the upper edge of the movable part 20. The member 39 abuts against the outer vertical part of the movable part. The member prevents the movable part and the fixed part from getting stuck between them. The figure shows how the curved surfaces of the plates allow the movable part to be rotated relative to the fixed part.

In Figures 3C, the movable part is rotated in the other direction according to the angle V1 relative to the fixed part. The outer part of the movable part 18, from the bucket, is rotated to a lower vertical position relative to the fixed part. The corner of the upper edge, in the direction of the bucket, on the fixed part abuts against the angled part of the upper edge of the movable part. The figure shows how the curved surfaces of the plates allow the movable part to be rotated relative to the fixed part.

Referring to Figure 3D, the movable member 20 is shown rotated at an angle V relative to the fixed member 18. The inner portion of the movable member 18 insert 10, in the direction of the bucket 2, the insert 10 is rotated (affected by the ground not shown in Figures). to a lower vertical position relative to the fixed part 18 and the bucket 2. The inner corner of the upper edge, in the direction of the bucket 2, on the fixed part 18 is positioned at a distance from the angled part (does not abut) of the upper the edge of the movable part 20. The member 39 abuts against the outer vertical edge of the movable part. The means 39 prevents the movable part 20 and the fixed part 18 from risking getting stuck together. The figure shows how the curved surfaces of the plates 37 allow the movable part 20 to be rotated relative to the grooves 38 in the fixed part 18.

In Figures 3E, the movable part 20 is rotated in the other direction according to the angle V1 relative to the fixed part 18. The outer part of the cutter 10 of the movable part 18, the bucket 2, is turned down to a lower vertical position relative to the fixed part. 18. The inner part, towards the bucket, of the movable part 20 is turned upwards to a higher vertical position relative to the fixed part and the bucket. The inner corner of the upper edge, in the direction of the counter scoop, on the fixed part 18 is positioned at a distance from the angled part (lies the edge) of the upper edge of the movable part 20. The member 39 abuts against the movable part outer vertical edge . The figure shows how the curved surfaces of the plates allow the movable part to be rotated relative to the fixed part.

Referring to Figure 4, a first alternative embodiment of the invention is shown. In this embodiment, the invention comprises a variant of a grating device 41, scraper device, which is placed in the rear part 42 of the bucket. The grating device 41 of the bucket substantially covers the entire width of the rear part of the bucket. Tear device 41 comprises at least one blade 43, planer blade, scraper blade, which extends through at least one opening 44 in the transverse direction of the bucket, i.e. extends over the width of the bucket. The scraper blade 43 is connected to at least one fastening device 45 at the opening 44. The fastening device 45 consists of a fastening device suitable for the purpose, such as screw connections. The angle of the blade 43 relative to the recess and the underside of the main body may vary. The planer blade 43 extends some distance downwards from the underside of the bucket 2.

In the exemplary embodiment, the bucket comprises at least one reinforcement 46 which holds the bottom of the bucket together with its rear inner part. In the exemplary embodiments, this comprises at least a first reinforcement 46 and at least a second reinforcement 46.

In the exemplary embodiment, each side member comprises at least one damper 47, buffer or the like. The damper 46 may be a rubber damper or other suitable damper. This does not exclude that this part, the damper 47, is not included in other embodiments.

The construction of the present scraper device has great advantages. For example, this can be used to scrape away ice and snow from a surface. Because the implement, the bucket, is equipped with wings, it is possible to scrape varying widths on a road. It is conceivable that the user when scraping can lay a string of the scraped next to the scoop. This is done, for example, by one of the wings being directed forwards and the other wing being directed backwards as shown in figure 5.

In the detailed description of the present patent application, details of the invention may be omitted which are obvious to a person skilled in the art to the field to which the invention relates. Such obvious details are included to the extent required for a satisfactory function to be obtained for the present invention. Although certain preferred embodiments have been shown in more detail, variations and modifications of the device may be apparent to those skilled in the art to which the invention pertains. All such modifications and variations are considered to fall within the scope of the appended claims. It is conceivable that the present scraper device is defined as a bucket.

The wings can be applied to other tools than the said bucket. It is thus conceivable that the bucket 2 consists of a dozer blade or the like. Advantages of the invention With the present invention a number of advantages are achieved. The most important is that at least one of the problems described in the background is eliminated or reduced.
