Description

  The present invention relates to a construction machine such as a wheel loader, its V-shaped bucket and its wear edge. More specifically, a V-shaped bucket that scoops up and conveys objects such as earth and sand, rough stone, and the like, provided on the construction machine, a wear edge for wear prevention that is attached to the front edge of the V-shaped bucket, and the above The present invention relates to a construction machine provided with a V-shaped bucket.

  As shown in FIG. 10, a construction machine 51 such as a wheel loader includes a bucket 52 that moves back and forth and up and down by a hydraulic drive at the front of the vehicle body. The bucket 52 is used for scooping up an object S such as earth and sand or rough stone and transporting it to a truck bed or the like. At this time, since the bottom portion of the bucket thrusts into the ground or the object to be transported, the wear of the front edge becomes severe. For this reason, a thick edge 53 is formed at the front end edge of the bucket. Usually, the edge 53 is attached to the front end edge of the bucket main body 52a by welding. However, if the edge 53 is also worn, the expensive bucket 52 must be replaced.

  In order to prevent wear of the bucket (edge), a blade member made of anti-wear steel called a wear edge 54 may be attached to the front edge of the edge 53 in some cases. The wear edge 54 is a plate-shaped member having a simple shape. The wear of the wear edge first prevents wear of the bucket body, which is much more expensive than the wear edge. For this purpose, the wear edge is usually detachably attached to the bucket body. When the wear edge wears out and cannot be used, it is replaced with a new one.

  Two types of bucket shapes, specifically, the shape of the front end edge (edge) of the bucket, V-shaped and linear, are well known. The straight edge is a rectangular plate-like member welded and connected along the straight front end edge of the bucket. A plurality of wear edges are attached to the linear edge so as to be aligned in a line (see, for example, Patent Document 1), and each wear edge has a rectangular shape in plan view. Therefore, if the front edge of the wear edge is worn, the same wear edge can be used again with the rear edge as a blade by removing each wear edge, rotating it 180 degrees and then reattaching it.

However, no such configuration is known for V-shaped edges.

Further, in the V-shaped bucket having the end wear edge having a rectangular shape according to the present invention, the end wear edge is rotated by 180 ° and reattached, or the left and right end wear edges are interchanged. Can be used multiple times.

  Hereinafter, a wheel loader, its V-shaped bucket, and its wear edge as an embodiment of the construction machine of the present invention will be described with reference to the drawings. FIG. 1 is a schematic view showing an embodiment of a wear edge of a V-shaped bucket for a wheel loader according to the present invention.

  The bucket 1 of FIG. 1 can be attached to the front part of a conventionally known wheel loader. Therefore, the description of the configuration of the wheel loader according to the present embodiment other than the bucket is omitted. The bucket 1 is detachable along the bucket body 1a, the V-shaped body edge 2 fixed to the front edge of the bucket body 1a by welding, and the V-shaped front edge of the body edge 2. The attached wear edges 3 and 4 are shown. The main body edge 2 has a substantially isosceles triangular shape in a plan view, and a base portion thereof is fixed to the front end edge of the bucket main body portion 1a. The isosceles sides of the body edge 2 intersect with each other at an angle α, and this intersection is the forefront of the body edge 2.

  The wear edges (hereinafter also referred to as oblique side edges) 3, 4 are attached to the front end edge of the V-shaped body edge 2, that is, both the right and left oblique sides. This oblique wear edge is composed of a left edge 3 and a right edge 4. The hypotenuse edges 3 and 4 have the same isosceles trapezoidal shape in plan view. That is, they all have the same shape. In the present embodiment, both the left side edge 3 and the right side edge 4 are mounted two by two. In each hypotenuse of the main body edge 2, the two hypotenuse edges coincide with each other and are arranged in a line without a gap, thereby exhibiting a parallelogram in plan view as a whole. The front edge of the left edge row and the front edge of the right edge row intersect with each other at an angle α, like the front edge isosceles of the main body edge 2.

  Note that the number of each hypotenuse edge is not limited to the above (two each). However, if all the hypotenuse edges have the same shape, the left and right hypotenuse edges 3 and 4 need to be an even number in order to obtain the effect described later by making the hypotenuse edges are isosceles trapezoids.

  As is apparent when referring also to FIG. 2, each of the oblique side edges 3 and 4 is provided with a bolt hole 5 to be attached to the main body edge 2 by a bolt B and a nut N. Bolt holes 6 are also formed in the vicinity of the front end edge of the main body edge 2 at portions corresponding to the bolt holes 5. The bolt holes 5 of the oblique sides 3 and 4 are formed along the longitudinal center line of the oblique sides. Furthermore, it is formed at a point-symmetrical position with respect to the center point of this center line (the centroid of the plan view shape). Of course, the bolt holes 6 of the main body edge 2 are formed corresponding to the positions of the bolt holes 5 of the respective hypotenuse edges 3 and 4. In short, the bolt holes can be bolted even if each hypotenuse edge 3, 4 is rotated 180 °, and can be bolted even if the left and right hypotenuse edges 3, 4 are repositioned. 5 and 6 may be arranged, and is not particularly limited to the center line in the longitudinal direction of the hypotenuse edge. This also applies to the other buckets 7, 11, 18, and 19 described later.

  As shown in FIG. 2, any hypotenuse edge is bolted to its lower surface so as to follow the front end edge of the main body edge 2. As is apparent from the cross section of the oblique side edge 3 shown in the figure, the front end edge and the rear end edge constitute a blade, and the upper corner C of the front and rear end edges is chamfered depending on whether it is flat or curved. . When the bucket 1 is used, the underside or front end edge of the hypotenuse edges 3 and 4 rub against the ground, or the front end edge is thrust into a transport object such as earth and rock, so that the hypotenuse edge 3 instead of the main body edge 2 is used. 4, the front edge is worn. In particular, the intersection T between the left and right oblique sides, which is the center portion of the edge row and the front end, and the left and right end portions E of the front end edge are most worn. When the leading edge T and both end portions E are worn, the main body edge 2 is worn, and the bucket 1 is not easily pushed into the object to be conveyed.

  Therefore, as shown in FIG. 3, by changing the posture and arrangement of the hypotenuse edges 3, 4, the non-wearing portions of the hypotenuse edges 3, 4 are positioned at the most distal portion T and the end E. By doing so, the thrusting function of the bucket 1 is restored. Specifically, as shown in FIG. 3A, the front end portions T of the left and right hypotenuse edges 3a, 4a near the center are worn, and the outer declination corner portions of the hypotenuse edges 3b, 4b near both sides. When E wears out (the wear part is indicated by a symbol M in the figure), after removing all the hypotenuse edges, as shown in FIG. 3 (b), the left side edge pairs 3a and 3b are rotated 180 °. At the same time, the set 4a, 4b of the right side edge is rotated by 180 ° and reattached. By doing so, the corner portions where the hypotenuse edges are not worn are located in both the most advanced portion T and both end portions E.

  As shown in FIG. 3 (c), when the most distal portion T and both end portions E are worn again by use, the entire hypotenuse edge is removed and, as shown in FIG. Is rotated clockwise by (180−α) ° and attached to the center of the right side, and the edge 3a on the left side is rotated clockwise by (180−α) ° and attached to the end of the right side. Further, the right edge 4b is rotated counterclockwise by (180−α) ° and attached to the center of the left edge, and the right edge 4a is counterclockwise by (180−α) °. Rotate and attach to the end of the left side. By doing so, the corner portions where the hypotenuse edges are not worn are located in both the most advanced portion T and both end portions E.

  As shown in FIG. 3 (e), when the leading edge T and both ends E are worn three times by use, after removing all the hypotenuse edges, as shown in FIG. 3 (f), a set of edges on the left side. 4a and 4b are rotated 180 ° and reattached, and the edge pairs 3a and 3b on the right side are rotated 180 ° and reattached. By doing so, the corner portions where the hypotenuse edges are not worn are located in both the most advanced portion T and both end portions E.

  As shown in FIG. 3 (g), when the foremost portion T and both end portions E are worn four times by use, all are replaced with new ones. Thus, by changing the posture of one hypotenuse edge three times, the four corners can be used sequentially. As shown in FIGS. 3 (b) to 3 (f), even if the wear part M is located at the rear end edge of the edge, there is no adverse effect on the thrusting function of the bucket. There is no problem in the thrusting function when the wear part M is located in the middle part.

  In this way, by forming the hypotenuse edges 3 and 4 that are detachably attached to the main body edge 2 into an isosceles trapezoidal shape in plan view, all four corners of each hypotenuse edge 3 and 4 can be used. As a result, the hypotenuse edge 3 4 lifespan can be extended. In order to obtain this effect for the hypotenuse edges having the same shape, the number of the hypotenuse edges 3 and 4 on the left and right sides is an even number as described above.

  In the above embodiment, the wear edge arranged so that the front end edge is completely V-shaped is exemplified, but the present invention is not limited to this configuration. It may be a wear edge arranged so as to be an isosceles trapezoidal front edge as a whole as described below. A bucket having an isosceles trapezoidal front edge is also included in the concept of a V-shaped bucket in a broad sense.

  FIG. 4 shows the bucket 7 whose front end edge is in the shape of an isosceles trapezoid. In this bucket 7, a plurality of wear edges are arranged and attached to the front edge of the isosceles trapezoidal body edge 8 so as to form an isosceles trapezoid. A plurality of central wear edges (center edges) 9 are detachably attached to the front edge of the main body edge 8 on the side (front side) perpendicular to the front-rear direction central axis CL formed at the center. A plurality of the oblique side wear edges 3 and 4 are removably attached to the oblique sides on both the left and right sides of the side, respectively. The hypotenuse wear edge is composed of two left side edges 3 attached to the left oblique side of the front edge of the main body edge 7 and two right side edges 4 attached to the right oblique side. All wear edges 3, 4, and 9 are arranged with almost no gap.

  Each of the central edges 9 has the same rectangular shape (including a square) in plan view. The two opposing sides are parallel and have the same length, and are attached so as to be parallel to the central axis CL in the front-rear direction of the main body edge 8. Both left and right hypotenuse edges 3 and 4 have the same isosceles trapezoidal shape in plan view. As shown in the figure, the wear edges 3, 4, 9 arranged in this way are also particularly susceptible to wear on the outer corners E of the left and right oblique sides due to long-term use, and the left and right corners T 1, T 1, T2 is also relatively easy to wear. In this case, the left and right hypotenuse edges 3 and 4 can use up the corners of the four corners by changing the posture and position in the same manner as described with reference to FIG. is there. Since this point has already been described, it will be omitted. The rectangular central edge 9 can be reversed by 180 ° to change the posture, and the left and right positions can be changed to use the corners of the four corners in the same manner. As described above, the lifetime of the entire wear edge can be extended.

  The number of the central edges 9 is not limited to two. One sheet or three or more sheets may be used.

  FIG. 5 shows a V-shaped bucket 11 in which three types of wear edges are detachably attached to the main body edge 12. Since the basic structure of the main body edge 12 is the same as that of the main body edge (FIG. 1), the description thereof is omitted. The wear edge includes a center wear edge (hereinafter referred to as a center edge) 13 attached to the central corner of the front edge of the V-shaped body edge 12, and ends attached to the left and right ends of the front edge of the body edge 12. Wear edges 14, 15 and oblique wear edges 16, 17 attached to the left and right oblique sides of the front edge of the main body edge 12, respectively. The end wear edge includes a left end edge 14 and a right end edge 15, and the oblique wear edge includes a left side edge 16 and a right side edge 17. Both hypotenuse edges 16 and 17 are arranged between the central edge 13 and the left and right end edges 14 and 15.

  The central edge 13 has a hexagonal shape in plan view, and two opposing sides thereof are parallel and have the same length, and are attached so as to be parallel to the central axis CL in the front-rear direction of the main body edge 12. Further, the two sides intersecting the front end edge and the two sides intersecting the rear end edge have the same shape, and the intersection angle thereof is the same as the angle formed by the front end edge of the left end edge 16 and the front end edge of the right end edge 17. It is. Further, the angle α formed by the left and right oblique sides of the front end edge of the main body edge 12 is also made substantially the same.

  The end edges 14 and 15 have the same shape, and have a rectangular shape (including a square shape) in plan view. Each end edge 14, 15 is attached so that its opposite two sides are parallel to the central axis CL in the front-rear direction of the main body edge 12.

  Both the hypotenuse edges 16 and 17 have the same parallelogram shape in plan view. In the present embodiment, both the left side edge 16 and the right side edge 17 are mounted. However, it is not limited to this number, and it may be one for each side or three or more. Further, the plan view shape of the hypotenuse edge is not limited to a parallelogram, and may be an isosceles trapezoid in the same plan view as shown in FIGS. The reason why the hypotenuse edge does not depend on the shape is that the four corners of the hypotenuse edges 16 and 17 are not particularly easily worn by attaching the central edge 13 and the end edges 14 and 15. However, when a plurality of hypotenuse edges are combined in each hypotenuse, it is desirable to select the shape of the edges so that the overall shape of the arranged plan view is a parallelogram as shown in the figure.

  Further, as described above with reference to FIG. 2, any of the wear edges 13, 14, 15, 16, and 17 are detachably attached to the main body edge 12 by bolts and nuts. In addition, as described above with reference to FIG. 2, each wear edge is chamfered depending on whether the upper corner C of the front and rear end edges is a flat surface or a curved surface so that the front and rear end edges constitute a blade.

  Similarly to the above-described bucket 1 (FIG. 1), the bucket 11 also wears most at the front end T at the center of the edge row and at the left and right ends E at the front edge due to long-term use. That is, the front edge of the center edge 13 and the corners outside the front edges of the end edges 14 and 15 are particularly easily worn.

  Therefore, as shown in FIG. 6, by changing the posture and arrangement of the central edge 13 and the end edges 14 and 15, the unworn portions of the edges 13, 14, and 15 Position E. By doing so, the thrusting function of the bucket 1 is restored.

  Specifically, as shown in FIG. 6A, when the front end T of the central edge 13 and the corner E on the outside of the front end of each of the end edges 14 and 15 are worn (in the figure, the worn portion is denoted by a symbol M). After removing these edges 13, 14, 15, the edges 13, 14, 15 are rotated by 180 ° and reattached as shown in FIG. 6B. By doing so, the edge portions 13, 14, and 15 of the corner portions where the tip portions T and the corner portions E are not worn are positioned.

  As shown in FIG. 6 (c), when the tip T and both ends E are worn again by use, as shown in FIG. 6 (d), the left edge 14 is attached to the right edge as it is without being rotated, and the right edge 15 Attach to the left end without rotating and replace the central edge with a new one. By doing so, the corners of the edges 23, 14, and 15 that are not worn are positioned on both the tip portion T and both end portions E.

  As shown in FIG. 6 (e), when the tip T and the ends E are worn three times by use, as shown in FIG. 6 (f), the end edges 15, 14 at the left end and the right end are respectively turned 180. Rotate and reattach, and also rotate the central edge 23 by 180 degrees and reattach. By doing so, the corner portions where the hypotenuse edges are not worn are located in both the tip portion T and the both end portions E. As shown in FIG. 6 (g), when the leading edge T and both ends E wear four times by use, the end edges 14 and 15 are replaced with new ones for the first time.

  As described above, by changing the posture or position of one end edge three times, the four corners can be used sequentially. However, the center edge must be replaced with a new one after being used twice. However, the used end edges 14, 15 with worn corners can be used as the central edge as described below.

  In FIG. 7, the used state where the corners E of the four corners of the left end edge 14 (FIG. 7A) and the right end edge 15 (FIG. 7B) are worn is indicated by a solid line and before use by a two-dot chain line. Shows the state. Further, the central edge 13 (FIG. 7C) before use is indicated by a solid line. Both used end edges 14 and 15 have a substantially hexagonal plan view shape similar to the central edge 13 before use. Therefore, by attaching one of the end edges 14 and 15 to the central portion of the front edge of the main body edge 12, it can be used as the central edge. In this way, if one bucket 11 is considered, if two central edges 13 are prepared first, after they are used up, used end edges are produced. This can be used as the central edge. For this purpose, it is desirable that both end edges 14 and 15 have a slightly longer length in the front-rear direction than the center edge.

  As described above, the isosceles trapezoidal hypotenuse edges 3 and 4 shown in FIGS. 1 to 4 and the center edge 13 and end edges 14 and 15 shown in FIGS. 5 to 7 are used alone or in combination. This makes it possible to extend the life of the edge. Other examples of edge combinations for such purposes are shown in FIGS.

  The bucket 18 shown in FIG. 8 includes the hypotenuse edges 3 and 4 shown in FIGS. 1 to 4 and the end edges 14 and 15 shown in FIGS. 5 to 7. Both the left side edge 3 and the right side edge 4 are arranged in an even number (two). In this bucket 18, the tip T of the row of the hypotenuse edges 3 and 4 is particularly susceptible to wear. Therefore, by changing the posture and position according to the same procedure as described with reference to FIG. The corners at the two corners can be used up and the life can be extended. Since this point has already been described, it will be omitted. The rectangular end edges 14 and 15 are inverted by 180 ° to change the posture, and then the left and right positions are changed to change the corners E of the four corners by the same procedure as described with reference to FIG. Can be used up. As described above, the lifetime of the entire wear edge can be extended. Since the bucket 18 shown in FIG. 8 does not use the center edge, the used end edges 14 and 15 cannot be used for the center.

  The bucket 19 shown in FIG. 9 includes oblique side edges 3 and 4 shown in FIGS. 1 to 4 and a central edge 13 shown in FIGS. 5 to 7. Both the left side edge 3 and the right side edge 4 are arranged in an even number (two). In this bucket 19, the corners E at the left and right ends of the row of the hypotenuse edges 3 and 4 are particularly easily worn. Therefore, by changing the posture and position in the same manner as described with reference to FIG. The corners at the two corners can be used up and the life can be extended. Since this point has already been described, it will be omitted. The hexagonal central edge 13 can be used up by using the same procedure as described with reference to FIG. As described above, the lifetime of the entire wear edge can be extended.

  The present invention is not limited to the combination of wear edges in the embodiment described above. It is within the scope of the present invention for those skilled in the art to select one of the isosceles trapezoidal hypotenuse edge, center edge, and rectangular end edge as needed, and to effectively combine two or more. is there.

  Moreover, as a means to attach a wear edge to a main body edge so that attachment or detachment is possible, not only a bolt nut but a well-known suitable means can be used.

  By applying the present invention to a wear edge attached to a V-shaped bucket of a construction machine such as a wheel loader, the life of the wear edge can be extended. As a result, it is possible to extend the life of the bucket.
