Bucket Field of the Invention

The present invention relates to a combined snow-throwing, sanding and salting device in a vehicle according to the preamble of claim 1.

Background of the Invention

Snowboarding and anti-skid activities for pedestrians, cyclists and vehicles, such as sanding and salting, on private and public roads, sidewalks, walking / biking trails, real estate entrances and exits, are most often performed by the same contractor / machine user. Such operations are carried out by means of snow plowing and sanding means combined with a tractor and / or loading machine, for example in the form of snow plows and / or buckets of various designs, types or designs. In snow plowing, snow plows are usually more effective than buckets. At present, a separate snowplow or snow bucket is generally used for snowploughing and, after snowploughing, a different sanding bucket for spreading sand or crushed stone.

The market is available eg. folding snow flaps made by various manufacturers (a multi-bucket introduced in the 1980s). The side-plate-shaped flaps are most often fitted on both sides of the snow bucket and secured by hinges to increase the snow plow width of the bucket. The side panels can be folded, i.e. folded inwards and outwards, by means of the hinges included, · · v, between 0 and 180 °, by means of one or more hydraulic units for controlling the hydraulic cylinders mounted on the side panels. Side panels are often flexibly hung to prevent them from breaking when a potential obstacle • • * occurs. SE C2-513718 discloses an example of this type of snow bucket. The sanding buckets include a frequently rotating feed / spreading roller at the back of the bucket and a mixing roller, which is guided by a hydraulic unit to grind, feed and distribute the sand out of the lower opening at the back of the bucket.

• · '• y * The problem with the individual snow plows and snow buckets described above: 30 and sanding buckets is that the operator has to change the snow bucket or snow plow to the sanding bucket after snow plowing or vice versa after sanding or salting. The machine owner should also invest in two • ♦ «* · * | tool or aggregate, that is to say a snow bucket or snow plow and a sanding bucket. This increases the cost of labor and working time as well as the costs of procurement, maintenance and storage of tools and other handling.

Brief Description of the Invention

It is therefore an object of the present invention to provide a solution to the problems mentioned above by providing an improved combined snow-plow, sand and salt bucket for the vehicle.

The present invention relates to a combined snow-throwing, sanding and salting device in a vehicle to which a bucket is removably attached. The bucket comprises inward and outwardly foldable side flaps for increasing the bucket snow plow 10 in the outwardly bent position and comprises at least one controllable device for applying sand, salt or the like. In one embodiment of the bucket, the controlled device is positioned inside the bucket at the rear of the bucket, whereby at least one movable cover inside the bucket covers it during snow plowing.

In another embodiment of the bucket, the sand / salt applicator is disposed at the rear edge of the bucket in a space defined by the bucket and roof.

In yet another embodiment, the space comprises at least a first opening for opening and closing the inside of the bucket for receiving sand / salt and at least a second opening for spreading sand / salt from the bucket.

118229 3:

This new combined snow plow and sand / salt spreading bucket has several benefits. The bucket reduces the number of tools to be stored from two to one, reducing the operator's workload and reducing work time by eliminating the need to replace the snow bucket or alternatively snow blade with the sanding bucket after each plow or sand application. The bucket also provides more flexibility in sand spreading because the width can be partially used for sand spreading so that the walking / bike path can be partially sanded, for example only half its width, allowing unobstructed sides of the road, for example, for people moving by kick. The combination scoop can be used in the same way as the sand scoop to spread the salt, though with greater flexibility. The bucket reduces the purchase cost and the need for maintenance by requiring only one tool for both snow plowing and sand / salt application.

The bucket 10 illustrated in Figures 1-4 comprises inwardly and outwardly foldable side flaps 20 which are movably connected to the front bucket head 10c through each of the foldable joints 21.

The back end 10d of the bucket is removably coupled to a non-shown vehicle stream by means of a tool holder of known shape and purpose. The bucket has two sides, a right side 11 and a left side 12, which together with the bottom 13 of the bucket and the back side 14 of the bucket forming essentially the back end 10d of the bucket define the bucket loading area / volume. The bucket 10 also has a leading edge 15 which extends along the front 10 of the entire bucket bottom 13 and includes removably mounted and therefore replaceable wear blades which come into contact with roads and other surfaces, and due to sand and salt, etc.

The front end 10c of the bucket is aligned with the upright side flaps 20 which are foldably connected to the vertical first ends 15 by means of vertical hinged joints 21 to the sides 11,12 of the bucket, the side flaps also comprising opposite vertical free ends. The side flaps increase the bucket width of the bucket because they can be pivoted / folded around the pivot axis of said joint 21 regardless of the bucket's folded-in position on the sides 11, 12 of the bucket, optionally by means of non-shown hydraulic or pneumatic known to the operator. In Fig. 1 to 3, the right flap 20 is shown in the inwardly folded side flap position • Il / Y, while the left side flap is shown in one outwardly folded position • * · «j among several other positions. the edges comprise 1 2 3 4 5 6 removable, and thus replaceable, wear blades 22 as the front edge 15.

: Figures 1-4 are shown the bucket 10, the inner half 10a of the rear part of the movable mask the 3 VA / liikuteitava cover 40, which together with the bucket sides 11,12 and a rear side 14 and the bottom 13 define / limit on the inner side of the space 50, ··. *. 30 whose cross-section at the back of the bucket 16 is a triangular 4 * · ', cf. Figure 4. The cover 40 protects the sanding * · ί · and saline applicator 30 placed inside the interior 50 so that the snow cannot be packed in when the 5 snow is plowed and impair or even ruin the function of the sanding / salting device 6.

* * * 35 The cover 40 is substantially spaced from the center in the longitudinal direction, i.e., across the vertical line of the bucket 10, to provide 118229 5 two separate movable roof cover spaces that form oblique standing cover plates (one plate 43 to the right, another plate 44 to the left). , cf. Figures 2,3), which can be displaced and guided longitudinally by the long sides 46 together with the guide profiles 45 sealed and extending to the sides 11,12 of the bucket. The profiles extend obliquely from the top of the back of the bucket 14 downwardly along the inside of the bucket 10a towards the front edge 15 of the bucket and down to the bottom 13 of the bucket.

The inclination / inclination of the cover plates 43, 44 and the guide profiles 45 with respect to the bucket 10 can be adapted to the size / structure of the bucket as well as the space required by the spreading device 30 and its sanding / salting and snow plowing capacity.

The sanding / salting applicator 30 is controlled by a machine operator from within a space 50 comprising at least a first inner opening 60 to be opened and closed via a cover 40 connected to the inside of the bucket 10a for receiving sand / salt 15 and at least one second to the outer side 10b. an outer opening 70 for applying sand or salt from below / outside the bucket 10b.

The size of the inner opening 60 determines the sanding / salting application capacity of the bucket 10. If the left cover plate 44 is moved or pulled up 20 (cf. Fig. 2) or if only the left cover plate 43 is pulled up the sand / salt bucket is only half its width / capacity.

:; γ If both cover plates 43, 44 are pulled up, an internal opening 60 will open up to the size (cf. Figure 3) and the bucket will sand or salt its entire width or capacity.

The roof plates 43, 44 are steplessly displaced independently of one another in the longitudinal direction: · · up and down in the bucket 10 via a hydraulic unit 34 operatively controlled by a machine operator by means of non-shown hydraulic or pneumatic cylinders and associated but not shown components by means of roads attached to the rear end 42 and the distance ·· * of the respective cover plate 43, 44. 30 I catch one of the cylinders to either open the space 50, that is, to pull up the cover plate * · [when the piston is moved out of the cylinder or when the piston is retracted into the cylinder and vice versa when the space 50 is closed. The hydraulic assembly 34 can φ ·· step-stop the movement of such a cover plate in any position between open and closed positions of each cover plate 43, 44. Machine user 35 may be able to manually move the cover plates from the back of the bucket and / or • · 118229 6 driver's cab by pulling the cover plates up and down using chains, pulleys and pulley systems or the like, although motoring is preferred.

Figures 1-3 illustrate a bucket bottom 13 of the inner side 10a and a bucket rear side 14 of upright-standing separating plate which is a plate strip 51 formed 5 sa and share both the bucket inner side 10a of the inner space 50 (see FIG. 3) in the vertical direction in two separate parts / area of the bucket. The dividing plate 51 divides the inner space 50 so that no sand or salt "" flows "over from the left side of the inner space 50 to the right side of the inner space behind the closed right cover plate 43. This allows as has been said that the only one of the width of the bucket 10 can be used, for example, pedestrian / bike the other side of the road sanding / salting-order, leaving the other side of hiekoittamatta / salt made.

The controlled applicator 30 comprises at least a first rotatable roll 31 within the width of the first bucket 10, which receives, mixes and comminutes the sintered, often frozen, sand / salt 15 through the inner opening 60. In this embodiment, said mixing roller 31 is disposed substantially parallel to at least one rotatable roller 32 adjacent to the outer side 10b of the bucket, which extends in the bucket width direction inside the space 50 to feed and distribute through an external opening 70 below the bucket rear edge 16. The action provided by these two tees 20, 31, 32 can also be accomplished by only one. . with a roller.

25 runs on vehicle (not shown) hydraulic oil.

The drive assembly 34 rotates the associated toothed drive wheel 35 through the toothed straps at the ends of each roller 31, 32 (cf. Figure 4), whereby the sand / salt is ground, fed in and then out through an opening 70 in the rear edge of the outer bucket. The rollers 31, 32 may also / or rotate by means of, for example, electric or internal combustion engines, although existing hydraulic units • · * "should be preferred. The toothed wheels 35 may instead be gears 35 which are guided by other gears or tooth · «»: ... · rods Another solution could be to use the rollers 31,32 · · · 35 to drive the wheels outside the bucket 10 directly connected to the ends of the rollers • · · ( not shown), lowered together with the bucket to roll contact with the ground for salting or alternatively sanding and at the same time 118229 7, the respective rollers 31,32 are rotated as the vehicle and wheels move forward so that the sand / salt is applied in support of the bucket.

The cover plate 40 may also be subdivided into more than two cover plates 43, 44, and may also remain undivided, i.e., remain a single le-5 cover covering the entire interior 50 when said space is complete, not divided by plates 51, bucket 10 along the entire width or space 50 may be subdivided into a plurality of discrete spaces on a plurality of plates 51. The number of divider plates 51 is not due to the number of cover plates 43, 44 used. The cover 40 can be divided directly across its width along the length of the bucket so that it can be bent in the same manner as the 10 venetian blinds by at least one longitudinal extension of the bucket (not shown) per division to provide less space in the sand / salt Levi position. However, this requires that the roof is made strong enough so that it does not twist / bend under the snow load and does not break or deteriorate.

The two rolls 31,32 comprise projections 33 formed by the sheet metal members 33. The sheet metal parts 33 are arranged one after the other in the longitudinal direction of the roll and are simultaneously displaced along the circumference of the roll, thereby forming a spiral shape. Spiral design means that the sand / salt to be received is mixed and disintegrated so that the projections 33 are connected or alternatively aligned with one another. , in other words, not exactly when the roller is rotating in the sand / salt, and reduces the risk of simultaneous toothing of several protrusions 33, for example, [*], why the frosting pit creates too much strain on the spreading device 30: 34 so that it stops. If the device stops, there is a safety function in the form of at least * * * 25 one overflow valve which causes the oil to circulate in a known manner so that the hydraulic pressure does not increase too and thus prevents the spreading device 30 from breaking. The tongue projections 33 further include both feed and ejection • · * functions on both rollers 31, 32 which resemble blades or buckets that work together to "pull out" and spread sand / salt evenly! ···, 30 divided by the lower 10 of the bucket opening 70.
