Description

WORK IMPLEMENT FOR CONSTRUCTION VEHICLE Technical Field [0001] The present disclosure relates to a work implement and a construction vehicle including the work implement.

Background

[0002] A construction vehicle, such as a wheel loader, typically includes a work implement coupled at a front end of the construction vehicle. The work implement, such as a bucket, may be used in mining and earth moving operations. For example, the work implement may be used to handle materials such as debris, soil, and the like. An amount of material that can be carried by the work implement is typically governed by a size of the work implement. Further, to handle large amounts of the material, the size of the work implement has to be large.

[0003] It is a prerequisite that an operator seated within an operator cabin of the construction vehicle is able to view a surrounding area of the construction vehicle during movement of the construction vehicle or while the construction vehicle is performing work operations. More particularly, the operator needs to have a clear view of the surrounding area to avoid collision of the construction vehicle with various obstructions present at a w-orksite. However, large sized work implements may impact a visibility of the operator. In some cases, the operator may have to stand up or tilt to view the surrounding area, which may cause operator fatigue. Further, camera systems are associated with the construction vehicle to achieve visibility around the construction vehicle. However, such camera systems may also fail to provide visibility at the front and/or the sides of the construction vehicle due to presence of large sized work implements.

[0004] U. S. Patent Number 4,309,142 describes a material handling element or bucket formed from two sidewalls and a backwall. The backwall has one or more apertures positioned in such a manner that the operator manipulating the bucket can see a portion of the leading edge of the bucket. In one embodiment, the apertures are positioned in such a manner that the leading edge can be viewed directly or in combination with one or more mirrors. In another embodiment, the apertures are positioned in such a manner so that the operator can sight one or more of the sidewalls of the bucket using those sidewalls as a guide for positioning the leading edge of the bucket.

Industrial Applicability

[0032] As per industrial regulations, it is desirable that the operator of the construction vehicle 100 is able to view the surrounding area of the construction vehicle 100 up to a certain distance. Accordingly, the present disclosure relates to the work implement 102 that includes the first opening 164, the second opening 180, and the number of third openings 148 that provide improved visibility to the operator while the operator is seated within the operator station 114. More particularly, the first opening 164 and the second opening 180 may provide improved visibility of the first and second sides 108, 110, and the number of third openings 148 may provide improved visibility of the front end 104.

[0033] It should be noted that the openings 164, 180, 148 are disposed high enough for the operator to view the surrounding area at various positions of the work implement 102. The size and a position of the openings 164, 180, 148 may vary based on dimensions of the work implement 102 such that the openings 164, 180, 148 allow the operator to view the surrounding area at various positions of the work implement 102. For example, the size and position of the openings 164, 180, 148 may be decided such that the surrounding area is visible when the work implement 102 is in the raised position or the lowered position. Such improved visibility may assist the operator to perform work operations in an efficient manner, while also complying with visibility requirements that are governed by industrial standards. Further, the openings 164, 180, 148 may improve work quality and reduce operator fatigue as the operator may not have to tilt or leave an operator seat to monitor the surrounding area of the construction vehicle 100. The operator may have a clear view of the surrounding area thereby reducing a possibility of contact with any obstructions at the worksite 103.

[0034] Further, the work implement 102 described herein does not include any chamfered edges, or other such geometrical features, that tend to reduce a capacity of the work implement 102. Thus, the present disclosure describes the work implement 102 that provides improved operator visibility while maintaining the capacity of the work implement 102. Further, the covering members 166, 182, 152 includes the perforated material that allows visibility of the surrounding area therethrough. Thus, the covering members 166, 182, 152 provide operator visibility while reducing any material spillage through the respective openings 164, 180, 148.

[0035] Moreover, when the construction vehicle includes the camera system, the openings 164, 180, 148 and the camera system may together assist in improving operator visibility of the surrounding area. Further, any need of repositioning the camera system to meet visibility requirements may also be eliminated. It should be noted that the work implement 102 may include another design/shape and mayss be associated with a number of different construction vehicles. Further, the openings 164, 180, 148 and the covering members 166, 182, 152 may be provided in existing construction vehicles. Moreover, such openings 164, 180, 148 and the associated covering members 166, 182, 152 may be associated with various work implements of different shapes and sizes.

[0036] While aspects of the present disclosure have been particularly shown and described with reference to the embodiments above, it will be understood by those skilled in the art that various additional embodiments may be contemplated by the modification of the disclosed machines, systems and methods without departing from the spirit and scope of what is disclosed. Such embodiments should be understood to fall within the scope of the present disclosure as determined based upon the claims and any equivalents thereof.
