Bucket, and work vehicle provided with same
By increasing the radius and slope of the bucket, a curved surface is formed to facilitate the sliding of objects, and the bulging part is used to compensate for the capacity, which solves the problem of object obstruction and stability in the existing bucket, and achieves smooth pushing and pushing of objects in the bucket. Stable shoveling ensures workload and excavation stability.

Problems solved by technology
[0007] However, in conventional buckets, when shoveling or excavating accumulated deposits or natural ground, etc., there is a problem that the object is pushed into the Objects remaining in the middle part of the inner side of the bucket hinder the storage of further pushed objects, making it impossible to smoothly shovel into the bucket, and the amount of work (throughput) cannot be ensured.

Embodiment Construction
[0031] Hereinafter, an embodiment of the present invention will be described based on the drawings.
[0032] figure 1 It is a side view showing the wheel loader 1 as the work vehicle of the present embodiment. Note that in each figure, based on the operator in the driving posture of the wheel loader 1, the front and rear direction of the vehicle body is only referred to as the front and rear direction, the width direction of the vehicle body is only referred to as the left and right direction, and the vertical direction of the vehicle body is only referred to as Up and down direction. In addition, the back side of the bucket refers to the rear side based on the opening of the bucket.
[0033] [Brief description of wheel loader]
[0034] in figure 1 Among them, the wheel loader 1 includes a vehicle body 2 made of steel. The vehicle body 2 includes a rear frame and a front frame 21 made of steel as a frame that is swingable in the left-right direction with respect to the rear frame....

A bucket (32), a lower front edge (43F) of which is provided in a straight linear shape, is equipped with: a first linear part (43) that extends horizontally from the lower front edge (43F) towards the back of the bucket; an inclined part (44) that is continuous with a back edge (43B) of the first linear part (43), extends further towards the back of the bucket, and is inclined upwards towards the back of the bucket; a curved part (45) that is continuous with a back edge (44B) of the inclined part (44) at a lower edge (45L), and is formed at a prescribed bucket radius (R); a second linear part (46) that is continuous with an upper edge (45U) of the curved part (45), and is inclined upwards towards the bucket opening; and a third linear part (48) that is bent towards the bucket opening by a bend part (47) at a front edge (46F) of the second linear part (46), and extends further towards the bucket opening.
Description
Technical field [0001] The present invention relates to a bucket and a work vehicle provided with the bucket. Background technique [0002] Conventionally, work vehicles such as wheel loaders have been provided with buckets constituting work equipment. As the cross section of such a bucket, there is known a middle part curved in a circular arc shape with a predetermined bucket radius, a bottom part extending linearly from the lower side of the middle part in the tangential direction of the circular arc, and A cross section in the shape of an upper part extending linearly from the upper side of the middle part in the tangential direction of the arc (for example, refer to Patent Document 1). [0003] Prior art literature [0004] Patent literature [0005] Patent Document 1: (Japan) Special Form No. 2013-526664 Summary of the invention [0006] The technical problem to be solved by the invention [0007] However, in a conventional bucket, when shoveling or excavating accumulated deposi...
