Description

[Technical Field]

[0001] The present invention relates to a work vehicle equipped with an engine. [Background technology]

[0002] As an example of a conventional work vehicle, as described in Patent Document 1, there is one that is equipped with a separator that separates and removes water from the fuel flowing through the fuel supply path from the fuel tank to the engine, and a platform on which a fuel tank for refueling the fuel tank can be placed. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-217276 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in conventional work vehicles, a support member for mounting the separator and a support member for mounting the mounting base are used, and these are supported on the traveling vehicle body.

[0005] In such work vehicles, the structure for attaching the separator and the mounting base to the running body is complex, and during manufacturing, the separator and the mounting base must each be attached to the running body, so the attachment process is time-consuming and there is room for improvement.

[0006] An object of the present invention is to provide a work vehicle that allows separators and mounting tables to be efficiently attached during manufacturing, and that allows the structure for attaching them to be simplified. [Means for solving the problem]

[0007] The work vehicle of the present invention comprises a running body, an engine mounted on the running body, a bonnet covering the engine, a fuel tank capable of storing fuel to be supplied to the engine, a mounting base capable of mounting a fuel tank for refueling the fuel tank, a separator mounted midway along a fuel supply path that supplies fuel from the fuel tank side to the engine side, which separates and removes moisture from the fuel flowing through the fuel supply path, and a support member that supports the mounting base and the separator.

[0008] According to this invention, the separator and the mounting base are supported by the same support member, which reduces the number of members required to support the separator and the mounting base on the traveling body, and simplifies the structure for attaching them.

[0009] Furthermore, during manufacturing, the support member to which the separator and the mounting base are already attached can be attached to the traveling body, making it possible to efficiently attach the separator and the mounting base during manufacturing.

[0010] In the present invention, it is preferable that the support member has an attachment portion that extends obliquely so that the front side is more inward in the left-right direction of the traveling body, and the separator is supported by the attachment portion.

[0011] With this configuration, the separator supported by the mounting portion can be attached to the traveling body with its front portion positioned on the inside of the traveling body in the left-right direction, which reduces the separator's protrusion to the outside of the traveling body in the left-right direction and allows for space-saving placement of the separator.

[0012] In the present invention, the separator has a main body portion and a rod-shaped portion that is longer than the length between one side edge and the other side edge of the main body portion when viewed in a plane, and it is preferable that the rod-shaped portion is arranged so that its longitudinal direction extends diagonally so that it is more inward in the left-right direction of the running body as it approaches the front.

[0013] With this configuration, the separator rod is attached to the traveling body with its front portion positioned on the inside of the traveling body in the left-right direction, which reduces the amount of protrusion of the rod outward from the traveling body in the left-right direction, thereby enabling space savings in the placement of the separator.

[0014] In the present invention, it is preferable that the support member be located forward of the rear end of the bonnet.

[0015] According to this configuration, the separator is attached to the sides and front of the hood, which makes it possible to increase the space around the driver's seat, which is generally located behind the hood.

[0016] In the present invention, it is preferable that a brake sensor capable of detecting the amount of depression of a brake pedal is provided, and that the brake sensor is supported by the support member.

[0017] According to this configuration, the separator, the mounting base, and the brake sensor are supported by the support member, which allows these to be attached more efficiently.

[0018] In the present invention, it is preferable that the vehicle be equipped with a driver's seat that is provided on the running body and in which a pilot can sit, and a rope that is provided behind the driver's seat and has a horizontal frame portion connected to the upper ends of the left and right vertical frame portions.

[0019] According to this configuration, the ROP is provided behind the driver's seat. Generally, the separator is often provided in front of the driver's seat near the engine, and in this case, the ROP is located behind the driver's seat and the separator is located in front of the driver's seat. The ROP and the separator, which are configured to protrude outward in the left-right direction of the aircraft, are distributed and located behind and in front of the driver's seat. As a result, it is possible to avoid inconveniences such as a configuration that protrudes outward in the left-right direction of the aircraft by attaching the separator so as to avoid the vertical frame portion of the ROP.

[0020] In the present invention, it is preferable that the vehicle is provided with a driving section in which a pilot sits and a cabin that covers the driving section, and that the support member is supported by a bracket that supports the cabin.

[0021] According to this configuration, since the bracket that supports the cabin is used, there is no need to provide a new structure for supporting the support member, which makes it possible to reduce the number of components. [Brief explanation of the drawings]

The side cover 38 is formed with a mesh-like side ventilation section 39 that allows air to flow through. Air can flow in the lateral direction between the inside and outside of the hood 24 through the side ventilation section 39.

[0035] A mesh-like front ventilation section 40 that allows air to flow is formed in the front plate section 36. Air can flow in the front-rear direction between the inside and outside of the hood 24 through the front ventilation section 40.

[0036] [Configuration of the mounting table] 2 and 3, in this embodiment, a support member 41 is supported on the right side portion of the clutch housing 21. The support member 41 supports a mounting base 42 on which a fuel tank for refueling the fuel tank 30 can be placed.

[0037] The mounting table 42 is supported by the support member 41 via a rotation mechanism 43. The rotation mechanism 43 allows the mounting table 42 to rotate about a front-to-rear axis P, as shown in Figures 3 and 4. This allows the mounting table 42 to be switched between a mounting position A1 in which the mounting surface 44 faces upward as shown by imaginary lines in Figures 3 and 4, and a storage position A2 in which the mounting surface 44 faces sideways as shown by solid lines in Figures 3 and 4.

[0038] 1 and 3, in this embodiment, the support member 41 is located forward of the rear end of the hood 24 and to the right of the right side cover 38. The mounting base 42 is located to the right of the engine 20 and the fuel tank 30.

[0039] [Separator configuration] As shown in FIGS. 1 to 3, a separator 46 for separating and removing water from the fuel is provided below the mounting table 42 and the rotating mechanism 43.

[0040] The separator 46 is provided in the middle of a fuel supply path that supplies fuel from the fuel tank 30 side toward the engine 20 side. The separator 46 separates and removes water from the fuel flowing through this fuel supply path.

[0041] The separator 46 is cylindrical and includes a main body 46a that separates and removes water from the fuel, and an upper portion 46b to which pipes (not shown) that connect the fuel tank 30 to the separator 46 and the separator 46 to the engine 20 are connected.

[0042] 4, the upper portion 46b has a rod-shaped portion 46c that is longer than the length between one side edge and the other side edge of the main body portion 46a in a plan view. In this embodiment, a pipe (not shown) connecting the fuel tank 30 and the separator 46 and a pipe (not shown) connecting the separator 46 and the engine 20 are connected to both ends of the rod-shaped portion 46c in the longitudinal direction, respectively.

[0043] [Separator support structure] 2 to 4, the separator 46 is supported by the support member 41 via an attachment portion 47. That is, the support member 41 supports the mounting table 42 and the separator 46.

[0044] 3 and 4, the mounting portion 47 is configured as a plate-like member having an upper surface 47a formed by bending the upper portion thereof. The mounting portion 47 is supported by the support member 41 in a state in which it extends obliquely so that the front side is inward in the left-right direction of the traveling body 1 (toward the "left side" in this embodiment).

[0045] 2 to 4, in this embodiment, the upper portion 46b of the separator 46 is attached to the attachment portion 47. Here, the rod-shaped portion 46c of the separator 46 attached to the attachment portion 47 is arranged so that the longitudinal direction of the rod-shaped portion 46c extends obliquely so that the more forward it is, the more inward in the left-right direction of the traveling body 1 (in this embodiment, the "left side").

[0046] In this embodiment, a drain 46d is provided in a lower portion of the separator 46. A stay 48 is provided between the drain 46d and the clutch housing 21 so as to extend in the front-rear direction of the traveling machine body 1.

[0047] The stay 48 has a front portion 48a formed by bending the front portion outward in the left-right direction of the traveling machine body 1 (to the "right side" in this embodiment).

[0048] The stay 48 is supported by the support member 41. A front surface 48a of the stay 48 is disposed so as to be located in front of the drain 46d.

[0049] In this embodiment, the support member 41 supports a brake sensor 49 that can detect the amount of depression of the brake pedal 13. That is, the support member 41 supports the mounting base 42, the separator 46, the stay 48, and the brake sensor 49.
