Description

[Technical field]

[0001] The present invention relates to a storage structure for a work machine that is provided on a body of the work machine. [Background technology]

[0002] In forestry work sites, vehicles with forestry attachments attached to work machines based on hydraulic excavators are used. A harvester, known as a forestry attachment, is set at the base of an upright tree, for example, and cuts the tree with a built-in chainsaw, then lays the tree on its side, fells the branches, and cuts them to a specified length.

[0003] Chainsaws used with attachments such as harvesters need to have their guide blades replaced when they become worn or damaged. Guide blades vary in length depending on the maximum felling diameter, i.e. the size of the attachment, but some can be longer than 1m.

[0004] Conventionally, some working machines are equipped with a tool box, which is a storage structure for storing tools and the like (see, for example, Patent Documents 1 and 2). However, such tool boxes do not easily store long objects such as blades. Therefore, in order to replace a spare guide blade on-site, the guide blade needs to be transported separately.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, the present invention will be described in detail based on an embodiment shown in FIGS.

[0016] Fig. 5 shows a work machine 10. The work machine 10 is a forestry work machine also known as a forestry machine. In this embodiment, the work machine 10 will be described as being based on a hydraulic excavator, which is a rotating work machine. In the example shown in the figure, the work machine 10 comprises a machine body 11 and a working device 12, which is a working arm movably provided on the machine body 11.

[0017] In this embodiment, the machine body 11 has a lower traveling body 13 that can travel by tracks or tires, an upper rotating body 14 that is rotatably mounted on the lower traveling body 13, and a cab 15 that is mounted on the upper rotating body 14 and surrounds a driver's seat where an operator sits. The working device 12 is disposed in the center of the upper rotating body 14 in the vehicle width direction, and the cab 15 is located on one side of the upper rotating body 14, that is, on the left side in the illustrated example, with respect to the working device 12. Note that each direction, such as up / down, left / right, front / rear, etc., is based on the viewpoint of the operator. Each part of the work machine 10 is operated by a fluid pressure actuator. The fluid pressure actuator is, for example, a hydraulic cylinder, a hydraulic motor, etc., and each operation is possible by supplying and discharging hydraulic oil, which is a working fluid discharged from a pump operated by an engine mounted on the machine body 11, with the flow rate and direction controlled by a control valve in response to the operation of the operator.

[0018] An attachment 16 is attached to the working device 12. In the illustrated example, the attachment 16 is a forestry attachment also called a harvester. The attachment 16 includes an attachment body 20 movably attached to the tip of the working device 12, and a pair of gripping arms 21, a pair of feed rollers 22, a cutter 23, and a chain saw 24, which is a cutting device, are each movably arranged on the attachment body 20. The attachment 16 cuts down a tree to be felled, for example, with the pair of gripping arms 21 gripping the tree, and presses the pair of feed rollers 22 against the surface of the felled wood, which is a material to be processed, so as to sandwich the wood, sends the wood out in the longitudinal direction, branches it with the cutter 23, and cuts it to a desired length (bucks) with the chain saw 24.

[0019] The chain saw 24 has a cutting attachment 26 that can be advanced and retreated by, for example, a fluid pressure actuator, and the cutting attachment 26 is driven by an electric motor that serves as a drive source. The cutting attachment 26 is configured by wrapping an endless saw chain 29 around the outer periphery of a long guide blade 28 shown in Fig. 4, and while the saw chain 29 receives power generated by the electric motor and rotates while being guided along the outer periphery of the guide blade 28, the cutting attachment 26 advances and retreats in a direction that intersects with the longitudinal direction of the wood fed by the feed roller 22 shown in Fig. 5, thereby felling or cutting the wood.

[0020] The guide blade 28 shown in Fig. 4 is a long object whose length is set according to the size of the attachment 16 (Fig. 5) selected according to the required maximum felling diameter. The guide blade 28 is detachable from the attachment 16 (Fig. 5) and can be replaced when worn or damaged.

[0021] In this embodiment, the spare guide blade 28 for replacement can be stored in a tool box 30, which is a storage structure provided in the upper rotating body 14 of the machine body 11 shown in FIG. 2. The tool box 30 is arranged on the other side of the upper rotating body 14 with respect to the working device 12 (FIG. 5), on the right side in the illustrated example, that is, on the opposite side to the cab 15 (FIG. 5). In the illustrated example, the tool box 30 is arranged adjacent to the left side of a side scaffolding section 31 formed on the right edge of the rotating frame 14a of the upper rotating body 14. In this embodiment, the front of the tool box 30 is covered by a protective member (guard member) 32. The protective member 32 is formed, for example, in the shape of a plate protruding upward from above the rotating frame 14a of the upper rotating body 14. A handrail 33, which is a gripped member that is gripped when ascending and descending to the side scaffolding section 31, is attached to the protective member 32.

[0022] 1(a), 1(b), 2, and 3, the toolbox 30 has a plurality of storage sections 35 and a storage space 37 that communicates with at least a plurality of adjacent internal spaces 36 among the plurality of storage sections 35. Long objects such as spare guide blades 28 are stored in the storage space 37.

[0023] The storage sections 35 each have an opening 39, and the internal space 36 can be accessed through the openings 39. The openings 39 can be opened and closed by an opening / closing body 40.

[0024] In this embodiment, the storage section 35 is provided with a first storage section 35a and a second storage section 35b.

[0025] The first storage section 35a is located at the frontmost part of the tool box 30. In this embodiment, the first storage section 35a is located at the front right part of the upper rotating body 14, which is the outer edge part of the machine body 11.

[0026] In the illustrated example, the first storage section 35a is formed in a box shape. The first storage section 35a has a pair of left and right side plates 42, 43, a pair of front and rear end plates 44, 45, and a ceiling plate 46, and is placed on the rotating frame 14a of the upper rotating body 14 and protrudes upward from the side scaffolding section 31. In this embodiment, the first storage section 35a is elongated in the front-rear direction. The first storage section 35a has a first opening 39a, which is an opening, and the first space section 36a, which is an internal space section, is accessible from the outside of the tool box 30 through the first opening 39a. In this embodiment, the first opening 39a is formed by cutting out the side plate 43 and the ceiling plate 46. In other words, the first opening 39a is opened above and to the side of the first storage section 35a, and the first space section 36a is accessible from the side of the machine body 11, that is, the side scaffolding section 31 on the right side in this embodiment. In the illustrated example, the first opening 39a is located at the front of the first storage portion 35a and is formed elongated in the left-right direction.

[0027] The first opening 39a can be opened and closed by a first opening / closing body 40a, which is one opening / closing body. The first opening / closing body 40a may have any opening / closing structure, but in this embodiment, it is attached to a ceiling board 46 by a hinge 47 and can be opened and closed in the vertical direction. In the illustrated example, the hinge 47 is located on the left side of the first opening / closing body 40a, which is the center side in the vehicle width direction, and the right edge of the first opening / closing body 40a rotates in the vertical direction to open and close the first opening 39a. In addition, the rear of the first opening 39a of the ceiling board 46 is covered by a first anti-slip portion 48, which is one anti-slip portion.

[0028] In this embodiment, the first storage section 35a is a tank storage section that stores a tank as a first stored object that is one of the stored objects. For example, a urea tank 49 that is a stored tank is stored in the first space section 36a inside the first storage section 35a. The urea tank 49 is connected to an exhaust gas treatment device that treats exhaust gas from an engine via a pipe, and stores urea used in the exhaust gas treatment device. At least a part of the urea tank 49 is located facing the first opening 39a. Therefore, the urea tank 49 is accessible from the first opening 39a when the first opening / closing body 40a is opened.

[0029] The second storage section 35b is located adjacent to the rear side of the first storage section 35a in the tool box 30. The second storage section 35b is disposed between the first storage section 35a and the power unit section 50, which is the section to be serviced located at the rear, on the right side of the upper rotating body 14, which is the outer edge of the machine body 11. In other words, the second storage section 35b is located adjacent to the power unit section 50 side of the first storage section 35a.

[0030] The power unit section 50 includes, for example, an engine, a pump, a generator, a battery, a working fluid tank, a fuel tank, a cooling device, and the like, and is covered by an openable and closable lid section 51. In this embodiment, a foothold section 52 is formed between the power unit section 50 and the second storage section 35b. That is, the foothold section 52 is adjacent to the front side of the power unit section 50, and the second storage section 35b (tool box 30) is adjacent to the front side of the foothold section 52. The foothold section 52 is set at a lower position than the lid section 51 of the power unit section 50.

[0031] In the illustrated example, the second storage section 35b is formed in a box shape. The second storage section 35b has a pair of left and right side plates 53, 54, a pair of front and rear end plates 55, 56, and a ceiling plate 57, and is placed on the revolving frame 14a of the upper revolving body 14 and protrudes upward from the side scaffolding section 31. In this embodiment, the storage section 35 closer to the power unit section 50 is set to be higher in height. That is, the height of the second storage section 35b closer to the power unit section 50 is higher than the height of the first storage section 35a farther from the power unit section 50. In this embodiment, the height of the second storage section 35b is higher than the first storage section 35a and lower than the scaffolding section 52. Therefore, the heights of the side scaffolding section 31, the ceiling panel 46 of the first storage section 35a, the ceiling panel 57 of the second storage section 35b, the scaffolding section 52, and the lid section 51 of the power unit section 50 increase in a stepped manner, and the ceiling panels 46 and 57 at the top of the toolbox 30 form a step extending from the side scaffolding section 31 to the scaffolding section 52.

[0032] In this embodiment, the side plates 53, 54 are formed integrally with the side plates 42, 43 of the first storage section 35a. A side rail 59 is formed on the side plate 54, which extends across the scaffold section 52 and is a gripped object that is gripped when ascending or descending to the scaffold section 52. The end plate 55 is formed integrally with the end plate 45 of the first storage section 35a and extends upward beyond the end plate 45.

[0033] The second storage section 35b has a second opening 39b, which is another opening, and the second space section 36b, which is another space section inside, can be accessed from outside the tool box 30 through the second opening 39b. In this embodiment, the second opening 39b is formed in the side plate 54. That is, the second opening 39b is opened on the side of the second storage section 35b, and the second space section 36b can be accessed from the side of the machine body 11, that is, from the side scaffold section 31 on the right side in this embodiment. In the illustrated example, the second opening 39b is located at the rear of the second storage section 35b.

[0034] The second opening 39b can be opened and closed by a second opening / closing body 40b, which is another opening / closing body. The second opening / closing body 40b may have any opening / closing structure, but in this embodiment, it is attached to the side plate 54 by a hinge and can be opened and closed in the left-right direction. In the example shown in the figure, the hinge is located on the rear edge side of the second opening / closing body 40b, and the second opening 39b is opened and closed by the front part of the second opening / closing body 40b rotating in the left-right direction. In addition, the ceiling plate 57 is covered by a second anti-slip part 61, which is another anti-slip part.

[0035] In this embodiment, the second storage section 35b is a tool storage section that stores tools and the like as second stored objects, which are other stored objects. For example, the second space section 36b inside the second storage section 35b can store tools for maintenance, containers such as cans containing oils and greases, or parts such as replacement pins.

[0036] The storage space 37 is formed by communicating the first space 36a inside the first storage section 35a and the second space 36b inside the second storage section 35b in the front-rear direction. That is, the storage space 37 is formed by opening a communication opening 63 in at least a part of the end plate 45 that serves as a partition between the first storage section 35a and the second storage section 35b. The front part of the storage space 37 is a part of the first space 36a, and the rear part of the storage space 37 is a part of the second space 36b. Therefore, the storage space 37 is formed in a longitudinal shape having a length equal to the total length of the first space 36a and the second space 36b in the front-rear direction.

[0037] The storage space 37 is formed by communicating at least the machine width center side of the interiors of any of the adjacent storage sections among the plurality of storage sections. In this embodiment, the storage space 37 is formed by communicating the left side of the first space 36a of the first storage section 35a and the second space 36b of the second storage section 35b, i.e., the working implement 12 (FIG. 5) side. In other words, the storage space 37 is positioned biased toward the working implement 12 (FIG. 5) side or the cab 15 side in the tool box 30.

[0038] The storage space 37 can be accessed from outside the toolbox 30 through an access opening 65. The access opening 65 is located at a different position from the first opening 39a and the second opening 39b. In this embodiment, the access opening 65 is formed in the ceiling plate 46 of the first storage section 35a. In the illustrated example, the access opening 65 is formed at the left edge of the ceiling plate 46, that is, at the edge opposite to the first opening 39a. Preferably, the access opening 65 is formed longitudinally along the longitudinal direction of the storage space 37. The access opening 65 may be formed at any position accessible to an operator, but in this embodiment, the access opening 65 is formed over substantially the entirety of the ceiling plate 46 in the longitudinal direction. Therefore, the access opening 65 is located adjacent to the left side of the first opening 39a and the first anti-slip portion 48.

[0039] The access opening 65 is opened and closed by an access opening / closing body 66. The access opening / closing body 66 may have any opening / closing structure, but in this embodiment, it is formed in a folding door shape and opens the access opening 65 while sliding forward along the ceiling board 46 and folding, as shown by the two-dot chain line in FIG. 1(a). This configuration ensures an opening and closing space for the access opening / closing body 66. Also, in this embodiment, the access opening / closing body 66 is formed with an opening / closing body anti-slip portion 67, which is adjacent to the first anti-slip portion 48 when the access opening 65 is closed to form an integrated anti-slip portion.

[0040] Next, the effects of the illustrated embodiment will be described.

[0041] The worker can access the first stored object stored in the first space 36a of the first storage section 35a through the first opening 39a by opening the first opening / closing body 40a. In this embodiment, the worker first climbs onto the side scaffolding section 31 and opens the first opening 39a by rotating the first opening / closing body 40a upward, thereby gaining access to the urea tank 49, which is the first stored object. The worker can then perform maintenance work such as supplying urea to the urea tank 49 and checking the remaining amount of urea in the urea tank 49.

[0042] Similarly, the worker can access the second stored object stored in the second space 36b of the second storage section 35b through the second opening 39b by opening the second opening / closing body 40b. In this embodiment, the worker first climbs onto the side scaffolding section 31 and opens the second opening 39b by rotating the second opening / closing body 40b backward, thereby enabling access to the second stored object, such as a tool. The worker can then take out the tool and perform various tasks.

[0043] Here, when performing work using the forestry attachment 16, there is a concern that the guide blade 28 of the cutting attachment 26 of the attachment 16 may be worn or damaged due to felling or cutting of trees, etc. For this reason, it is desirable to store a spare guide blade 28 in the tool box 30. However, the guide blade 28 is a long object, and is therefore difficult to store in the first space 36a of the first storage section 35a and the second space 36b of the second storage section 35b.

[0044] In the present embodiment, the toolbox 30 has a storage space 37 that communicates with the interiors of the first storage section 35a and the second storage section 35b that are adjacent to each other and that can be accessed from an access opening 65 different from each opening 39. Therefore, the storage space 37 can be made to have a length that spans the interiors of the plurality of storage sections 35, and in this embodiment, a length that spans the interiors of the first storage section 35a and the second storage section 35b, so that a long object can be stored in the storage space 37 and taken out from the storage space 37 through the access opening 65. In this embodiment, a worker can climb up to the ceiling board 46 and open the access opening / closing body 66 to store a long object in the storage space 37 or take out a long object from the storage space 37 through the access opening 65. Therefore, the storage space 37 can be used to load spare guide blades 28 or long tools, such as an axe with a long handle, onto the work machine 10, eliminating the need to transport these separately and making it possible to quickly replace the guide blades 28 at the work site or to carry out work using long tools.

[0045] Furthermore, by forming the access opening 65 longitudinally along the longitudinal direction of the storage space 37, it becomes easier to insert a long object into the storage space 37.

[0046] In order to allow a longer object to be stored in the storage space 37, the object may be stored at an angle relative to the storage space 37. For example, by disposing a support for supporting the object at an angle inside the storage space 37, the storage space 37 can be used at an angle to allow a longer object to be stored in the storage space 37, and by inclining one end of the object so that it is closer to the access opening 65, the object can be easily removed from the access opening 65.

[0047] Furthermore, in forestry work, since the work machine 10 travels along unleveled mountain paths, it is expected that the vibrations of the work machine 10 will be large, and therefore it is preferable that a means for fixing the stored long objects be formed in the storage space 37. For example, in order to fix the long objects in the storage space 37 using a fixing member such as a band or string, by forming a fixing auxiliary device such as a hole through which the fixing member can be passed or a hook for hanging the fixing member in the storage space 37, it becomes possible to stably fix the stored long objects.

[0048] Moreover, by arranging the first storage section 35a and the second storage section 35b adjacent to each other in sequence from the outer edge of the airframe 11 toward the power unit section 50, and by setting the height of the second storage section 35b closer to the power unit section 50 higher than the height of the first storage section 35a farther from the power unit section 50, the first storage section 35a and the second storage section 35b can form a step for accessing the power unit section 50 from the outer edge of the airframe 11. Therefore, by using the first storage section 35a and the second storage section 35b as a foothold, it becomes possible to easily access the power unit section 50 and perform maintenance on the power unit section 50.

[0049] Furthermore, in a configuration in which the tool box 30 is disposed at the front of the upper rotating body 14 of the machine body 11, the height of the first storage section 35a, which is located relatively forward, is set relatively low, so that the front of the tool box 30 is unlikely to obstruct the view when viewed from the driver's seat inside the cab 15, ensuring visibility to the lower right front of the operator.

[0050] In addition, since the first storage section 35a and the second storage section 35b are disposed on the side of the machine body 11 and the inside can be accessed from the side of the machine body 11, that is, the right side in this embodiment, through the first opening 39a and the second opening 39b, the storage space section 37 is formed by communicating the inside of the first storage section 35a and the inside of the second storage section 35b on the machine body width center side, that is, the left side position opposite the side of the machine body 11, so that the long object stored in the storage space section 37 does not hinder access to the first stored object stored in the first storage section 35a and the second stored object stored in the second storage section 35b. In particular, since the urea tank 49 stored in the first storage section 35a needs to be accessed more frequently than the long object stored in the storage section 37, the long object stored in the storage space section 37 does not hinder access to the urea tank 49, and workability can be ensured.

[0051] In the above embodiment, the storage space 37 is formed by connecting the interiors of the multiple storage sections 35 through the pre-opened communication openings 63. However, this is not limited to the above, and an opening / closing member capable of opening and closing the communication openings 63 may be provided so that the interiors of the storage sections 35 are connected to each other and the storage space 37 is formed only when the opening / closing member is opened.

[0052] In addition, the toolbox 30 is configured to include two storage sections 35, the first storage section 35a and the second storage section 35b, but is not limited to this, and may be configured to include three or more storage sections 35. In this case, the storage space section 37 is formed to communicate the interiors of at least two of the storage sections 35 adjacent to each other, thereby achieving the same effects as those of the above embodiment.

[0053] Furthermore, the part to be serviced is not limited to the power unit section 50, but may be any other part to be serviced. [Industrial Applicability]

[0054] The present invention has industrial applicability to businesses involved in the manufacturing, sales, and other industries of forestry work machines. [Explanation of symbols]
