[0010] The work vehicle of the present invention is designed to operate while traveling in a field, performing work using implements. One embodiment of the work vehicle of the present invention, a tractor 1, will be described with reference to the drawings. As shown in Figure 1, the tractor 1 comprises a body 2 and implements 3 (see dashed line), and is configured to perform work such as tilling using the implements 3 while traveling on the body 2. Various implements 3, such as rotary tillers, harrows, loaders, and box scrapers, are attached to the body 2 of the tractor 1 as needed. The tractor 1 is equipped with a toolbox 4 for storing tools used for maintenance of various parts.

[0011] A pair of front wheels 10 are provided on the lower front of the vehicle body 2, and a pair of rear wheels 11 are provided on the lower rear of the vehicle body 2. In this embodiment, as shown in Figure 1, an example is described in which the front wheels 10 are made up of tires and the rear wheels 11 are made up of half-crawlers, but in other examples, the rear wheels 11 may be made up of tires, or full crawlers may be provided instead of the front wheels 10 and rear wheels 11.

[0012] The front of the vehicle body 2 houses the engine 12, which is covered by a bonnet 17. Behind the engine 12, a transmission 13 is located between the pair of rear wheels 11. Power from the engine 12 is transmitted to the transmission 13, which changes the gear ratio before transmitting the power to each of the front wheels 10 and each of the rear wheels 11. At the rear of the vehicle body 2, a work implement lifting mechanism 14 and a work implement angle changing mechanism 15 are provided as drive units for driving the work implement 3 using hydraulic pressure from hydraulic fluid.

[0013] At the rear of the transmission 13 are a pair of left and right lower links 20, a top link 21, and a PTO shaft 22, with each lower link 20, top link 21, and PTO shaft 22 extending to the rear. The work implement 3 is connected to the rear ends of each lower link 20, top link 21, and PTO shaft 22 and is driven by the PTO shaft 22.

[0014] The work implement lifting mechanism 14 includes a pair of left and right lift arms 23 and a lift cylinder (not shown) composed of a hydraulic cylinder. The tip of one lift arm 23 is connected to one lower link 20 via a link member 24, and the tip of the other lift arm 23 is connected to the other lower link 20 via a rolling cylinder (not shown). The work implement lifting mechanism 14 can change the height of the work implement 3 supported by the vehicle body 2 by driving the lift cylinder by the hydraulic pressure of the hydraulic oil supplied from a hydraulic pump (not shown) of the transmission 13.

[0015] The work implement angle changing mechanism 15 includes a rolling cylinder composed of a hydraulic cylinder. As described above, the rolling cylinder is configured to connect the other lift arm 23 and the other lower link 20. The work implement angle changing mechanism 15 can change the lateral inclination posture of the work implement 3 supported by the vehicle body 2 by driving the rolling cylinder by the hydraulic pressure of the hydraulic oil supplied from the hydraulic pump of the transmission 13.

[0016] On the upper part of the vehicle body 2, a cabin 16 for the operator to board is provided. Inside the cabin 16, a driver's seat 30 for the operator to sit on is provided, and various operating tools are provided around the driver's seat 30. On the lower parts of the left and right outer sides of the cabin 16, steps 32 serving as footrests when the operator gets on and off the cabin 16 are provided. Also, outside the cabin 16, a toolbox 4 for storing tools is provided.

[0017] For example, as an operating tool, a steering wheel 31 for operating the steering of the front wheels 10 is provided in front of the driver's seat 30. Around the steering wheel 31, there are provided a lift lever (not shown) for forcibly moving and operating the working machine 3 to the uppermost position or the lowermost position, a forward / backward switching lever (not shown) for switching the traveling direction of the vehicle body 2 between forward and backward, etc. On the floor surface below the steering wheel 31, there are provided a brake pedal (not shown) for braking the vehicle body 2, a clutch pedal (not shown) for operating a clutch (not shown) for switching the transmission / interruption of power, an accelerator pedal (not shown) for accelerating and decelerating the rotational speed of the engine 12 (the vehicle speed of the vehicle body 2), etc.

[0018] As shown in FIGS. 1 and 2, a fuel tank 33 for storing fuel supplied to the engine 12 and a reductant tank 34 for storing a reductant such as urea water to be mixed with the exhaust gas discharged from the engine 12 are provided at the lower part of the vehicle body 2. By mixing the reductant with the exhaust gas, nitrogen oxides (NOx) in the exhaust gas are reduced.

[0019] The fuel tank 33, for example, has a tank body 33a that is divided into two left and right parts and is elongated in the traveling direction, and an introduction part 33b that extends obliquely upward from the left tank body 33a. At the upper part of the introduction part 33b, a fuel filling port 33c for filling fuel is provided. The fuel tank 33 is arranged on the side of the body of the tractor 1. The two tank bodies 33a are respectively arranged on both sides in the left-right direction of the body. Specifically, they are arranged inside the steps 32 in the left-right direction below the cabin 16.

[0020] The introduction section 33b extends from below the cabin 16 toward the front and upward, and wraps around the left step 32 from the inside in the left-right direction, reaching the side (left side) of the bonnet 17 (engine 12) and in front of the left step 32. As shown in Figures 1, 2, 3, and 4, the fuel filler neck 33c is located in front of the cabin 16 and on the side (left side) of the bonnet 17 (engine 12), and is also positioned facing upward. Fuel supplied through the fuel filler neck 33c is introduced through the introduction section 33b and stored in the tank body 33a. The introduction section 33b and the fuel filler neck 33c are located behind the left front wheel 10 and in a position that does not interfere with the left front wheel 10.

[0021] The reducing agent tank 34 is positioned on the side of the tractor 1, specifically in front of the left tank body 33a and left step 32 of the fuel tank 33, and on the side (left side) of the bonnet 17 (engine 12), and below at least a portion of the inlet 33b of the fuel tank 33 (including the fuel filler port 33c). As shown in Figures 1, 2, 3, and 4, a water inlet 34a facing sideways (left side) is provided on the upper part of the side (left side) of the reducing agent tank 34 for injecting the reducing agent into the reducing agent tank 34. The reducing agent tank 34 and the water inlet 34a are positioned behind the left front wheel 10 and in a position that does not interfere with the left front wheel 10.

[0022] As shown in Figure 3, the toolbox 4 is formed in an elongated shape when viewed from above, and its longitudinal direction is aligned with the direction of travel of the tractor 1. As shown in Figures 1, 2, and 3, the toolbox 4 is positioned in front of the cabin 16 (driver's seat 30) and behind the left front wheel 10. The toolbox 4 is positioned in the left-right direction of the tractor 1, inside the water inlet 34a of the reducing agent tank 34 and outside (to the left) of the bonnet 17 (engine 12), and further positioned above the reducing agent tank 34. Here, the toolbox 4 may be positioned so as to overlap with the right portion of the water inlet 34a of the reducing agent tank 34 in the left-right direction, but it is positioned to avoid overlap with the water inlet 34a.

[0023] Furthermore, the toolbox 4 is positioned so as to overlap with at least a portion of the fuel tank 33 in a side view (for example, the upper part of the fuel filler port 33c and the inlet 33b), and is positioned inward from the fuel filler port 33c of the fuel tank 33 in the left-right direction of the tractor 1's body, and is positioned in front of the left side of the tank body 33a of the fuel tank 33. Here, the toolbox 4 may be positioned so as to overlap with the portion of the fuel tank 33 to the right of the fuel filler port 33c in the left-right direction, but is positioned to avoid overlap with the fuel filler port 33c.

[0024] Furthermore, the toolbox 4 may be positioned inside the reducing agent tank 34 in the left-right direction, and may also be positioned inside the left front wheel 10. In addition, the toolbox 4 may be positioned above the introduction portion 33b of the fuel tank 33, and may also be positioned so as to overlap with at least a part of the fuel tank 33 (for example, the introduction portion 33b) when viewed from above.

[0025] As shown in Figure 2, a mounting portion 35, such as a stay, for attaching the toolbox 4 to the body of the tractor 1 is provided at the front corner (left front corner) of the cabin 16. The cabin 16 is supported by a box-shaped cabin frame 16a, and the mounting portion 35 is provided on the cabin frame 16a that supports the cabin 16 on the left front side and is formed to protrude forward.

[0026] As shown in Figures 1, 2, 3, and 4, the toolbox 4 is fixed to the toolbox fixing part 36 and is also attached to the mounting part 35 via the toolbox fixing part 36. The toolbox fixing part 36 is formed in an L-shape, for example as shown in Figure 5, with one side of the toolbox fixing part 36 extending horizontally (front-to-back direction) protruding forward from the left front cabin frame 16a, and the other side of the toolbox fixing part 36 extending vertically attached to the mounting part 35.

[0027] As shown in Figures 5 and 6, the toolbox fixing section 36 has a connecting section 37 that connects to the toolbox 4, and the toolbox 4 is fixed to the upper side of the toolbox fixing section 36 by the connecting section 37. The connecting section 37 is made up of, for example, bolts that fasten the bottom surface of the toolbox 4 to the upper surface of the toolbox fixing section 36.

[0028] The bottom surface of the toolbox 4 is provided with a predetermined number of fastening holes (at least two), and one side of the toolbox fixing part 36 is provided with through holes 38 corresponding to each fastening hole, as shown in Figure 6. The through holes 38 are formed on one side of the toolbox fixing part 36 in the normal position in which the orientation of the toolbox 4 is fixed so that the longitudinal direction of the toolbox 4 is parallel to the direction of travel of the tractor 1. The connecting part 37 is fastened to the fastening holes via the through holes 38, thereby fixing the toolbox 4 to the toolbox fixing part 36 in the normal position in which the longitudinal direction of the toolbox 4 is parallel to the direction of travel of the machine.

[0029] As described above, according to this embodiment, the tractor 1, which is a work vehicle, is equipped with a driver's seat 30 in which the operator sits and a toolbox 4 for storing tools, the toolbox 4 being positioned in front of the driver's seat 30.

[0030] As a result, in tractor 1, the driver's seat 30 and cabin 16 are configured to be easily accessible to the operator, and by placing the toolbox 4 in front of the driver's seat 30 and cabin 16, access to the toolbox 4 is improved, thereby improving work efficiency and convenience, and the operator does not need to interfere with the implement 3 in order to access the toolbox 4.

[0031] Specifically, the tractor 1 is further equipped with a reducing agent tank 34 located on the side of the machine, and the toolbox 4 is positioned inward from the water inlet 34a of the reducing agent tank 34 in the left-right direction of the machine.

[0032] This prevents the reducing agent from spilling onto the toolbox 4 even if some of the reducing agent is poured into the reducing agent tank 34 on the tractor 1. Furthermore, since the reducing agent tank 34 is designed to be easily accessible to the operator, positioning the toolbox 4 inside the water inlet 34a of the reducing agent tank 34 improves accessibility to the toolbox 4, thereby enhancing work efficiency and convenience.

[0033] Furthermore, according to this embodiment, the toolbox 4 is positioned above the reducing agent tank 34.

[0034] As a result, in tractor 1, by positioning the toolbox 4 above the reducing agent tank 34, the operator can access the toolbox 4 without being obstructed by the reducing agent tank 34, thereby improving accessibility to the toolbox 4 and enhancing work efficiency and convenience.

[0035] Furthermore, according to this embodiment, the tractor 1 further comprises a fuel tank 33 located on the side of the machine body, and the toolbox 4 is positioned so as to overlap with at least a portion of the fuel tank 33 in a side view.

[0036] This allows the toolbox 4 to be positioned at a height that is not obstructed by the fuel tank 33 in the tractor 1, improving access to the toolbox 4 and thus enhancing work efficiency and convenience.

[0037] Furthermore, according to this embodiment, the toolbox 4 is positioned so that its longitudinal direction aligns with the direction of travel of the machine.

[0038] As a result, in tractor 1, the toolbox 4 is positioned vertically from the perspective of the operator seated in the driver's seat 30. Therefore, the toolbox 4 does not obstruct the operator's view when checking parts such as the front wheels 10 at the front of tractor 1, thus ensuring safety.

[0039] Furthermore, according to this embodiment, the tractor 1 further comprises a cabin 16 having a driver's seat 30, a toolbox fixing part 36 for fixing a toolbox 4, and a mounting part 35 for attaching the toolbox fixing part 36 to the machine body, the mounting part 35 being provided at the front corner of the cabin 16.

[0040] As a result, in tractor 1, by providing mounting parts 35 such as stays on the highly rigid cabin 16, the toolbox fixing part 36 can be attached to the machine body with high strength, and the toolbox 4 can be fixed to the machine body with even greater strength.

[0041] In other embodiments, the tractor 1 may be equipped with a front loader (not shown) extending forward from the side of the bonnet 17. As shown in Figures 7 and 8, the front loader is attached to a front loader bracket 40 that extends forward from both sides of the bonnet 17 in the left-right direction of the tractor body 1. The front loader bracket 40 is rotatable around a pivot axis extending in the left-right direction below the bonnet 17 and is configured to rotate up and down. The front loader is supported by the front loader bracket 40 so as to be rotatable up and down.

[0042] In other embodiments, the toolbox 4, positioned to the side of the bonnet 17, may be positioned so as not to interfere with the vertically rotating front loader bracket 40. For example, the connecting portion 37 that connects the toolbox 4 to the toolbox fixing portion 36 is positioned outside the front loader bracket 40 in the left-right direction of the tractor 1, and the toolbox 4 is positioned outside the front loader bracket 40. This allows the toolbox 4 to be positioned and fixed by the connecting portion 37 without interfering with the vertically rotating front loader, even when the front loader is attached to the front of the tractor 1.

[0043] In this case, the toolbox fixing portion 36 that secures the toolbox 4 is formed in a shape that does not interfere with the front loader bracket 40 which rotates up and down. Specifically, it is preferable to cut out one side of the toolbox fixing portion 36, at the end of the toolbox fixing portion 36 closest to the front loader bracket 40 (for example, the right front end).

[0044] Furthermore, the connecting part 37 that fixes the toolbox 4 to the toolbox fixing part 36 is configured to allow the orientation of the toolbox 4 to be changed between a normal orientation in which the longitudinal direction is parallel to the direction of travel of the tractor 1 and a non-interference orientation in which it does not interfere with the front loader bracket 40.

[0045] In this case, as shown in Figures 8 and 9, on one side of the toolbox fixing portion 36, in addition to the through hole 38a in the normal position, a through hole 38b in a non-interference position is formed as a through hole 38 to which the connecting portion 37 is connected, so as to fix the posture of the toolbox 4 so that it does not interfere with the front loader bracket 40. The non-interference position through hole 38b is positioned so that the connecting portion 37 is connected outside the front loader bracket 40 in the left-right direction of the tractor 1 body.

[0046] Then, the connecting portion 37 is fastened to the fastening hole of the toolbox 4 via the through hole 38a in the normal position, so that the toolbox 4 is fixed to the toolbox fixing portion 36 in the normal position. On the other hand, if the connecting portion 37 is fastened to the fastening hole via the through hole 38b in the non-interference position, the connecting portion 37 is positioned outside the front loader bracket 40 in the left-right direction, and the toolbox 4 is fixed to the toolbox fixing portion 36 in a non-interference position. As a result, when the front loader is configured to be detachable from the front of the tractor 1, the position of the toolbox 4 can be changed as needed and fixed to the machine body without changing the toolbox fixing portion 36. For example, when a front loader that rotates up and down is attached, the toolbox 4 can be positioned in a non-interference position that does not interfere with the front loader and fixed by the connecting portion 37.

[0047] Alternatively, the connecting portion 37 may be configured to support the toolbox 4 so that it can rotate horizontally with respect to one side of the toolbox fixing portion 36, thereby allowing the orientation of the toolbox 4 to be changed between a normal orientation and a non-interference orientation.

[0048] In this embodiment, the toolbox 4 is described as being located on the left side of the tractor 1 in the left-right direction, more specifically, on the left side of the bonnet 17 and at the left front corner of the cabin 16. However, the present invention is not limited to this example. In other examples, the toolbox 4 may be located on the right side in the left-right direction, more specifically, on the right side of the bonnet 17 and at the right front corner of the cabin 16.

[0049] Furthermore, in this embodiment, an example was described in which a mounting portion 35 is provided at the front corner of the cabin frame 16a supporting the cabin 16, and the toolbox 4 is attached to the mounting portion 35 via a toolbox fixing portion 36. However, the present invention is not limited to this example. In other examples, a mounting portion 35 may be provided on another frame of the tractor body 2, and the toolbox 4 may be attached to the mounting portion 35 of the other frame via a toolbox fixing portion 36.

[0050] In the embodiments described above, an example was shown in which the work vehicle of the present invention is composed of a tractor 1. However, the present invention is not limited to this example, and the work vehicle of the present invention may be composed of other agricultural machinery or other work vehicles.

[0051] Furthermore, the present invention may be modified as appropriate, provided that it does not contradict the gist or idea of ​​the invention as can be read from the claims and the specification as a whole, and work vehicles with such modifications are also included in the technical concept of the present invention.
