Summary of the Invention

Problems to be Solved by the Invention

[0004] Since the heights of the left and right side surfaces of the bucket of the snow removal tool described in Patent Document 1 are the same, snow exceeding the capacity of the bucket overflows on both sides of the bucket. Therefore, in order to remove the snow spilled on both sides passed by the bucket, it is necessary to remove the snow again on each of the left and right sides of the bucket, which takes time and effort for the snow removal work.

[0005] The present invention has been made in view of the above circumstances, and an object thereof is to provide a bucket capable of efficiently removing snow and earth and sand.

Means for Solving the Problems

[0006] A first aspect of the present invention is characterized in that the bucket includes a loading surface on which an object to be removed is loaded, a left side surface erected from the left side of the loading surface, and a right side surface erected from the right side of the loading surface, and an accommodation space for the object formed by the loading surface, the left side surface, and the right side surface is formed asymmetrically with respect to the left and right.

[0007] Preferably, the bucket is attached in front of a work machine. [Effects of the Invention]

[0008] According to the present invention, a bucket that can efficiently remove snow and soil can be provided. [Brief explanation of the drawing]

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Throughout the drawings, the same components are denoted by the same reference numerals, and redundant descriptions are omitted.

[0011] <First Embodiment> The first embodiment is an embodiment in which the present invention is applied to the bucket of a snow removal tool. In the first embodiment, the object to be removed is snow. Throughout this specification, "removal" includes not only the case of removing an object for the purpose of disposal but also the case of removing an object from its existing location for the purpose of moving or accumulating it.

[0012] FIG. 1 is a comparative explanatory view of a snow removal tool 1 according to the first embodiment and a conventional example.

[0013] The snow removal tool 1 according to the first embodiment includes a bucket 10, a support rod 20, and a grip 30.

[0014] The support rod 20 is a rod-shaped member having one end fixed to the back surface of the bucket 10.

[0015] The grip 30 is provided at the other end of the support rod 20 (the end opposite to the bucket 10).

[0016] The bucket 10 includes a loading surface 11, a left side surface 12L, and a right side surface 12R.

[0017] The loading surface 11 functions as a support surface for the object on which the snow, which is the object to be removed, is loaded.

[0018] The loading surface 11 is formed in a curved surface shape including a bottom surface 11a and a rear surface 11b that rises from the rear of the bottom surface 11a.

[0019] The left side surface 12L stands upright from the left side of the loading surface 11.

[0020] The right side surface 12R stands upright from the right side of the loading surface 11.

[0021] The height of the right side surface 12R is formed higher than the height of the left side surface 12L.

[0022] The left side 12L and the right side 12R are configured as flat or non-flat plate-like bodies, taking into consideration the strength required for the object.

[0023] Preferably, the rear surface 11b of the loading surface 11 is formed so that the depth on the right side is greater than the depth on the left side. That is, the loading surface 11 is formed by an asymmetrical, non-planar plate-like body (non-flat).

[0024] Figure 1A is an explanatory diagram that emphasizes the asymmetry of the bucket 110 in Figure 1. The left side surface 12L and left depth may be formed to be deeper, as with the bucket 10 of the snow removal device 1 shown in Figure 1, or the right side surface 12R and right depth may be formed to be deeper, as with the bucket 10' of the snow removal device 1'.

[0025] Conventional buckets 110 have a loading surface 111, a left side 112L, and a right side 112R. The loading surface 111 is symmetrical, and the height of the left side 112L and the height of the right side 112R are the same. Therefore, the storage space inside the bucket 110 is symmetrical.

[0026] Figure 2 is an explanatory diagram showing the usage state of the bucket 10 according to the first embodiment.

[0027] When the user grasps the grip 30 and the support rod 20 and pushes the snow removal tool 1 forward within the snow-covered area, the snow is collected on the loading surface 11.

[0028] Eventually, when the snow accumulated on the loading surface 11 exceeds the capacity of the bucket 10, snow overflows from the lower left side 12L to the left in the direction of travel of the bucket 10. On the other hand, the right side 12R is higher than the left side 12L, so snow does not overflow to the right in the direction of travel of the bucket 10.

[0029] As a result, the path taken by snow removal tool 1 will only accumulate snow on the left side in the direction of travel of snow removal tool 1, and not on the right side, eliminating the need to clear snow from the right side of the path again.

[0030] In contrast, with the conventional bucket 110, when the amount of snow collected exceeds the bucket's capacity, the left side 112L and the right side 112R are at the same height, causing the snow to overflow to both the left and right sides in the direction of travel of the snow removal tool 1. Therefore, it becomes necessary to clear the snow from both sides of the path again. Thus, the snow removal tool 1 equipped with the bucket 10 according to the first embodiment can perform snow removal work more efficiently than the snow removal tool 101 equipped with the bucket 110 according to the conventional example.

[0031] Figure 3 shows an example of a bucket according to the first embodiment being mounted on a snow removal device.

[0032] The snow removal devices 2a and 2b shown in Figure 3 differ in the shape of their buckets 10a and 10b. The configuration of the arm 40 is the same for both. First, let's explain snow removal device 2a.

[0033] The arm 40 of the snow removal device 2a is formed in a roughly U-shape. One end of the arm 40 is joined to the upper right end of the bucket 10a, and the other end is joined to the upper left end of the bucket 10. As a modified example, instead of joining to the upper ends on both sides, it may be joined to the left and right sides or the back of the loading surface 11.

[0034] The arm 40 is joined to the bucket 10a at two points, left and right. This allows the bucket 10a to be pushed from two points, even if the volume of the contents differs on the left and right sides due to the asymmetrical nature of the bucket 10a, resulting in an uneven load balance on the bucket 10a from the contents. This makes it easier to move the snow removal tool 2 forward.

[0035] Furthermore, the height from the ground at the joint between the left open end of arm 40 and bucket 10a, and the height from the ground at the joint between the right open end of arm 30 and bucket 10a are made equal. This allows for more stable thrust transmission compared to cases where the heights from the ground at the left and right joints are different, and is expected to improve work efficiency when the bucket 10a is rolled over, forward, or reversed to maintain horizontality with the ground and for snow removal.

[0036] The rear surface 11b of the bucket 10a is formed in an asymmetrical curved shape, where the height on the right side of the rear surface 11b is higher than the height on the left side of the rear surface 11b.

[0037] The height of the right side surface 12R is greater than the height of the left side surface 12L, and is formed in continuity with the rightmost edge of the rear surface 11b.

[0038] The height of the left side surface 12L is formed continuously with the leftmost edge of the rear surface 11b.

[0039] The bucket 10b of the snow removal device 2b differs from bucket 10a in that its left side 12L is higher than its right side 12R, and its rear surface 11b is formed in an asymmetrical curved shape where the height of the left side of the rear surface 11b is higher than the height of the right side of the rear surface 11b. The other configurations are the same for buckets 10a and 10b.

[0040] Thus, the right side can be made higher, or the left side can be made higher.

[0041] Figure 4 shows variations of the bucket of a snow removal device equipped with the bucket according to the first embodiment.

[0042] Bucket 10c is a bucket in which the loading surface 11, the right side 12R, and the left side 12L are all formed as nearly flat surfaces, with the right side 12R being higher than the left side 12L.

[0043] Bucket 10d has a loading surface 11 with the same shape as bucket 10c, but with the left side 12L higher than the right side 12R. In other words, it is the same shape as bucket 10c but with the left and right sides reversed.

[0044] The bucket 10e is formed in a roughly trapezoidal shape, where the height of the right side of the rear surface 11b is higher than the height of the left side of the rear surface 11b.

[0045] The height of the right side surface 12R is greater than the height of the left side surface 12L, and is formed in continuity with the rightmost edge of the rear surface 11b.

[0046] The left side surface 12L is formed in continuity with the leftmost edge of the rear surface 11b.

[0047] Bucket 10f is formed in a roughly trapezoidal shape, with the left side of the rear surface 11b being higher than the right side of the rear surface 11b, and the left side 12L being higher than the right side 12R. In other words, it is the same shape as bucket 10e but with the left and right sides reversed.

[0048] The bucket 10g has a curved loading surface 11, a curved right side 12R, and a curved left side 12L, with the right side 12R being higher than the left side 12L.

[0049] Bucket 10h has a loading surface 11 with the same shape as bucket 10g, but with the curved left side 12L higher than the curved right side 12R. In other words, it is the same shape as bucket 10g but with the left and right sides reversed.

[0050] Figure 5 shows an example of a bucket according to the first embodiment mounted on a shovel.

[0051] The shovel 4a in Figure 5 comprises a bucket 10i, a support rod 20, and a grip 30.

[0052] The loading surface 11 of the bucket 10i comprises a bottom surface 11a and a rear surface 11b that rises smoothly from the bottom surface 11a.

[0053] Furthermore, the bucket 10i has a right side surface 12R that rises smoothly from the bottom surface 11a. The height of the right side surface 12R is higher than the left end surface 12EL of the loading surface 11 and is formed in continuity with the rightmost end of the rear surface 11b.

[0054] The left end 12EL of the loading surface 11 does not have a left side surface 12L.

[0055] In other words, a right side surface 12R is provided on the right side of the loading surface 11, but a left side surface is not provided on the left end 12EL, and the bucket 10i is formed asymmetrically.

[0056] Bucket 10j has a left side surface 12L that rises smoothly from the bottom surface 11a. The height of the left side surface 12L is higher than the right end 12ER of the loading surface 11 and is formed continuously with the leftmost end of the rear surface 11b. In other words, bucket 10j has the shape of bucket 10i with the left and right sides reversed.

[0057] Figure 6 shows variations in the shape of the support rod, arm, and grip connected to the bucket according to the first embodiment.

[0058] As shown in Figure 6, the grip shape may be a straight type without a grip (support rod 20 only), or it may be a grip 30a with a hollow section.

[0059] Alternatively, a rod-shaped grip 30b connected to the support rod 20 in a roughly T-shape may be used.

[0060] Furthermore, the curved portion of the U-shaped arm 40 may be used as the grip 30c.

[0061] The bucket 10 according to the first embodiment includes a loading surface 11 on which objects to be removed are loaded, a left side surface 12L erected from the left side of the loading surface 11, and a right side surface 12R erected from the right side of the loading surface 11, and the object storage space 13 formed by the loading surface 11, the left side surface 12L, and the right side surface 12R is formed asymmetrically.

[0062] Figure 7 shows an example in which the support rod 20 is formed to be detachably attached to the bucket 10g. Although Figure 7 uses a bucket 10g as an example, the explanation is not limited to a bucket 10g.

[0063] The back surface of the 10g bucket is provided with support rod holders 15 and 15a for holding the ends of the support rods 20.

[0064] The support rod holder 15 is formed in a cylindrical shape, with one end fixed to the back surface of the loading surface 11 and the other end open.

[0065] When using, insert the end 21 of the support rod 20 into the support rod holder 15.

[0066] According to the embodiment shown in Figure 7, snow removal tools such as snowplows, shovels, and spades are equipped with a bucket and a support rod, the support rod being detachably connected to the rear side (opposite side of the storage space) of the rear surface of the bucket.

[0067] This allows the 10g bucket and the support rod 20 to be stored separately, making storage easier. Since snow removal equipment is not used in the summer, easier storage improves usability.

[0068] Figure 8 shows another example in which the support rod 20 is formed to be detachable from the bucket.

[0069] Bucket 10k, which has a higher right side 12R, and bucket 10l, which has a higher left side 12L, are each equipped with a support rod holder 15.

[0070] The support rod 20 includes a central rod (shaft) 20M and a hand rod 20a connected to the central rod 20M.

[0071] The handle 20a is equipped with the grip 30a shown in Figure 6, but it may also be a handle 20b without a grip, or a handle 20c equipped with a T-shaped grip 30c.

[0072] The handle 20a is equipped with a spring (leaf spring) 22 on the opposite side of the grip 30a.

[0073] On the side of the central rod 20M that connects to the handle rod 20a, a through groove (not shown) is formed through which the spring 22 protrudes when the handle rod 20a is connected.

[0074] The connecting side of the central rod 20M to the support rod holding section 15 is equipped with a spring (leaf spring) 22M.

[0075] On the side of the support rod holder 15 that connects to the central rod 20M, a through groove (not shown) is formed through which the spring 22M protrudes when the central rod 20M is connected.

[0076] A snow removal tool is formed by connecting a 20M central pole to a 10K bucket, and then connecting one of the handle poles 20a, 20b, or 20c.

[0077] The support rod may not have a central rod 20M, but rather a support rod 20d in which a grip 30a is formed on a single rod-shaped member. The support rod 20d also has a snap 22 formed on it.

[0078] If you want to reverse the left-right asymmetry of the storage space, replace the 10k bucket with a 10l bucket.

[0079] This allows for the reversal of the left-right asymmetry of the storage space. Depending on the work area, such as when you want to accumulate the objects on the left side in the direction of travel of the snow removal equipment (for example, when the snow melting ditch is on the left side in the direction of travel) or on the right side (for example, when the snow melting ditch is on the right side in the direction of travel), you can selectively attach the 10k or 10l bucket to improve work efficiency.

[0080] As explained above, according to the bucket of the first embodiment, the object overflows from the lower side of the height between the left side 12L and the right side 12R, and does not overflow from the higher side. Therefore, the removal work only needs to be performed on one side of the bucket 10's trajectory, improving work efficiency. As a result, any object exceeding the capacity of the storage space 13 inside the bucket 10 overflows from the side with the smaller capacity, so the removal work only needs to be performed on one side of the bucket 10's trajectory, making the removal work more efficient.

[0081] <Second Embodiment> The second embodiment is an embodiment in which the bucket according to the present invention is mounted on the bucket of a work machine.

[0082] Figure 9 is an explanatory diagram showing the usage state of the bucket (wheel loader) according to the second embodiment.

[0083] The wheel loader 50 comprises a machine body 51 and a front work implement 55.

[0084] The aircraft 51 is equipped with tires 52 and a cab 53.

[0085] The tire 52 corresponds to the vehicle that enables the wheel loader 50 to move.

[0086] The cab 53 houses either a driver's seat for the wheel loader 50 operator or a remote control receiver. The cab 53 is located above the tires 52.

[0087] The front work machine 55 is attached to the front of the aircraft body 51 so as to be able to be tilted up and down.

[0088] The front work implement 55 is equipped with a left arm 54L, a right arm 54R, and a bucket 10m.

[0089] A bucket 10m is connected to the front end of the left arm 54L and the front end of the right arm so that it can be tilted up and down.

[0090] The bucket 10m may be an attachment (detachable member) that is detachably formed on the front end of the left arm 54L and the front end of the right arm 54R, or it may be connected and fixed to the front end of the left arm 54L and the front end of the right arm 54R so as to be able to be tilted up and down.

[0091] The 10m bucket includes a loading surface 11, a left side 12L, and a right side 12R.

[0092] The length of the bottom surface 11a of the loading surface 11 in the depth direction is formed to be shorter than the length of the rear surface 11b in the height direction.

[0093] The area of ​​the right side surface 12R is larger than the area of ​​the left side surface 12L.

[0094] Bucket 10m has an asymmetrical storage space for objects; more specifically, the contact surface with the object in bucket 10m is wider on the right side of bucket 10d. Therefore, when the amount of object exceeds the capacity of bucket 10m, it overflows from the left side of bucket 10m. As a result, even if the overflowed object accumulates on the left side of the wheel loader 50's travel trajectory, it does not accumulate on the right side. This means that the object collection work can be performed again on the left side of the travel trajectory, improving work efficiency.

[0095] Instead of the 10m bucket, a 10n bucket may be provided on the front work implement 55.

[0096] Bucket 10n has a larger area on its left side 12L than on its right side 12L. The other configurations are the same as bucket 10m.

[0097] Figure 10 is an explanatory diagram showing the usage state of the bucket (bulldozer) according to the second embodiment.

[0098] The bulldozer 60 consists of a main body 61 and a front work implement 65.

[0099] The aircraft 61 is equipped with crawler tracks 62 and a cab 63.

[0100] The Crawler 62 is equivalent to the undercarriage that enables the Bulldozer 60 to operate.

[0101] The front end of the front work implement 65 is equipped with a bucket 10o.

[0102] The bucket 10o is formed with an asymmetrical, non-planar plate-like structure (non-flat), where the area of ​​the right side surface 12R is larger than the area of ​​the left side surface 12L.

[0103] Bucket 10p may be provided on the front work implement 61 instead of bucket 10o.

[0104] Bucket 10p has a larger area on its left side 12L than on its right side 12L. The other configurations are the same as bucket 10o.

[0105] In the second embodiment, the bucket 10 is mounted on the front of a work machine such as a wheel loader 50 or a bulldozer 60.

[0106] More specifically, the work machine comprises a machine body and a front work implement, the machine body comprises a traveling body and a cab mounted above the traveling body, the front work implement comprises at least one arm and a bucket, the rear end of the arm is connected to the machine body so as to be able to be tilted up and down, the bucket is connected to the front end of the arm so as to be able to be tilted up and down, the bucket comprises a loading surface on which objects to be removed are loaded, a left side erected from the left side of the loading surface, and a right side erected from the right side of the loading surface, and the object storage space formed by the loading surface, the left side, and the right side is formed asymmetrically.

[0107] Preferably, the work machine comprises a pair of arms, one on the left and one on the right, and the bucket is connected to the front end of each of the arms so as to be able to be tilted up and down.

[0108] Preferably, the bucket is detachably connected to the arm. Figure 11 shows an example of the present invention being implemented on a dozer blade.

[0109] The dozer blades 70a and 70b in Figure 11 are attachment-type dozer blades used on the front work implement 65 of the bulldozer 60.

[0110] The dozer blade 70a has a curved loading surface 11, a right side 12R, and a left side 12L.

[0111] The dozer blade 70a is formed with an asymmetrical, non-planar plate-like structure (non-flat), with the area of ​​the right side 12R being larger than the area of ​​the left side 12L.

[0112] The dozer blade 70b is formed with an asymmetrical, non-planar plate-like structure, where the area of ​​the left side 12L is larger than the area of ​​the right side 12R.

[0113] Depending on the usage of the bulldozer 60, the dozer blades 70a and 70b can be appropriately selected and attached as the front implement 65, improving usability.

[0114] According to the work machine of the second embodiment, since the object overflows from only one side of the work machine's travel trajectory, the removal work only needs to be performed on that one side again, thereby improving work efficiency.

[0115] The bucket of this invention can be modified in various ways without altering the essence of the invention.

[0116] For example, the height of the left side surface 12L may be made higher than the right side surface 12R, and the area of ​​the left side surface 12L may be made larger than the area of ​​the right side surface 12R.

[0117] For example, the present invention may be applied to the bucket of a shovel or spade. The objects to be removed are not limited to snow, but may also include soil, fertilizer, animal feed, cement, grains, seashells, and fallen leaves.

[0118] Furthermore, the above embodiment is merely one of the best possible forms at present. For example, the bucket 10 may be made of metal or resin.

[0119] Furthermore, in the above embodiment, the work machine may be a hydraulic excavator. The hydraulic excavator comprises a machine body, a boom connected to the machine body so as to be able to be tilted up and down, an arm rotatably connected to the front end of the boom, and an attachment (removably formed) bucket at the front end of the arm, and the present invention may be applied to the bucket.
