BUCKET COMPRISING BLADE ASSEMBLY FIELD id="p-1" id="p-1"

[0001] least one blade assembly.

The present invention relates to a bucket, especially to a bucket comprising at BACKGROUND id="p-2" id="p-2"

[0002] to surface layers, such as snoW and ice. Slipperiness can cause serious injuries to users of Road and pavement surfaces can be extremely slippery during the Winter due the roads and pavements, such as bone fractures due to falls. Slipperiness can be reduced by sanding or gritting. id="p-3" id="p-3"

[0003] sanding/gritting material, such as sand and crushed stone, during Winter and collecting of it HoWever, sanding and gritting causes high cost due to spreading of the after Winter, aside of remarkable material and logistics costs. In addition, usage of the sanding/gritting material for slippery prevention causes several types of health and environmental issues. Applied sanding/gritting material increases formation of road dust composed of different sizes of particles, from Which especially inhalable particles can cause even serious health problems for maintenance Workers, the users of the roads and pavements and other parties and inhabitants exposed to the road dust. In addition, despite applying the sanding/gritting material, sometimes a sufficient coefficient of friction is not achieved. Thus, falls cannot be prevented Well enough. id="p-4" id="p-4"

[0004] of sand and stone is leading to ever-increasing transport distances, Which increases Moreover, sand and stone are non-reneWable resources. The non-reneWability environmental emissions and logistics costs. Over time, problems With the availability of rock material arise. Furthermore, the sanding/gritting material cannot be usually reused due to debris and contaminants. The cleaning of the sanding/gritting material is challenging and time consuming and thus very expensive. That°s Why the most of the sanding/gritting material ends up as hazardous Waste to landfills. id="p-5" id="p-5"

[0005] by a road grader. HoWever, due to large size of the road grader it cannot be used in small In addition, slipperiness can be prevented by removing the ice or snoW layer yards and pavements. In addition, the method used by the road grader contains a high risk of damaging the road structures aside of breaking the ice or snoW layer. Altematively, a tool for grinding the ice or snoW layer can be attached to a smaller Work machine. HoWever, these kinds of tools are designed only for that single purpose. Furthermore, the tools may not provide enough pressure to break the surface layer properly. Thus, there is still a need to improve safety of the roads and pavements by reducing slipperiness.

[0042] FIGURES l and 2 illustrate a bucket l0 having a front side and an opposite back side, comprising at least one blade assembly 20 arranged to the bucket l0 on the back side. A combination of the bucket and blade assembly enables using the bucket for different purposes. The blade assembly can be used for puncturing and breaking the surface layer, such as snow and ice. The bucket can be used to move and lift snow and ice, for example. The bucket can be also used with or without the blade assembly for example, for gardening. Hence, the combination can be used in a variety of different ways and is not tied to just one use. So, it reduces need for purchasing and storing of different tools for different purposes. It also reduces need for changing of tools for different tasks. However, if needed, the blade assembly can be easily removed from the bucket for using the bucket without blade assembly. When the bucket is connected to the work machine, it can be used to increase pressure of the blade assembly. Then, the blade assembly is pressed by the bucket towards the road surface for more efficient puncturing and breaking of the surface layer. The bucket also enables increasing the puncturing pressure by external load, such as material for slipperiness prevention or snow, if needed, which enables efficient usage even by lighter, smaller and more agile work machines with lower environmental emissions. id="p-43" id="p-43"

The suspension The blade assembly can be lifted up in the recess by moving the suspension element 54 can be moved in the upper position for example, by loosening the suspension by rotating the spring tension adjustment screw of the spring perch 60 of the threaded suspension adjustment rod 55 and lifting the suspension element 54 up by rotating the fastening means 58, such as the lock nut, of the threaded suspension adjustment rod 55. Altematively, when the blade assembly 20 will not be utilized for a longer period of time, the suspension element 54, such as the spring 56, can also be removed completely from between the mounting element 53 and a ﬂange or a holder attached or formed to the bucket. This enables of lifting the blade assembly 20 to its top position in the recess 11 and using the bucket without of the blade assembly so that the blade assembly does not affect the operation of the bucket. id="p-86" id="p-86"

[0086] there is no need for it or for the maintenance of the blade assembly.

The blade assembly 20 can be also easily removed from the bucket 10 when id="p-87" id="p-87"

[0087] of snow or ice on a surface or treating the ground, such as ﬂuffing or turning over the soil According to some embodiments, the bucket 10 is used for breaking a layeror Weeding.
