DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The following is an explanation of an embodiment of the present invention with reference to the drawings. In this embodiment, a tractor is used as an example of a work vehicle, but other than tractors, various types of riding work vehicles such as harvesters, rice transplanters, combine harvesters, civil engineering and construction work equipment, and snowplows can also be considered as work vehicles.

[0010] In addition, in this specification, directions are defined as follows. First, the direction in which a tractor, which is a work vehicle, travels during work is defined as "front", and the opposite direction is defined as "rear". Furthermore, the right side of the tractor's travel direction is defined as the right, and the left side is defined as the left. The direction perpendicular to the front-to-rear and left-to-right directions of the tractor is defined as the up-down direction. In this case, the direction of gravity is defined as down, and the opposite side is defined as up. In the drawings, the front direction is indicated as F, the rear direction as B, the left direction as L, the right direction as R, the up direction as U, and the down direction as D, as appropriate.

[0011] 1 is a side view showing a schematic configuration of a tractor 1, which is an example of a work vehicle according to this embodiment. The tractor 1 includes a body 2. The front portion of the body 2 is supported by a pair of left and right front wheels 3. The rear portion of the body 2 is supported by a pair of left and right rear wheels 4.

[0012] A bonnet 5 is disposed at the front of the vehicle body 2. An engine 6 serving as a drive source is disposed below the bonnet 5. That is, the tractor 1 includes the engine 6 and the bonnet 5 that covers the engine 6. The engine 6 is, for example, a diesel engine, but is not limited thereto, and may be, for example, a gasoline engine.

[0013] A driver's seat 7 in which a driver (operator) sits is provided behind the engine 6 in the vehicle body 2. A steering wheel 8 for the driver to steer and a driver's seat 9 for the driver are provided in the driver's seat 7. The steering wheel 8 is supported rotatably by a steering column 10. That is, the tractor 1 is equipped with the steering column 10 located in the driver's seat 7. The driver's seat 7 is also provided with an operating lever LV, a pedal P, etc. that are operated by the driver.

[0014] A three-point link mechanism is provided on the rear side of the vehicle body 2. The three-point link mechanism includes a pair of left and right lower links 11 and an upper link (not shown). A working machine can be attached to the three-point link mechanism. Examples of the working machine that can be used include, but are not limited to, a cultivator, a plow, and a fertilizer applicator. In addition, a lifting device (not shown) having a hydraulic device such as a lifting cylinder is provided on the rear side of the vehicle body 2. The lifting device raises and lowers the three-point link mechanism, thereby raising and lowering the working machine.

[0015] A rope frame 12 is provided behind the driver's seat 7 (driver's seat 9) in the vehicle body 2. The tractor 1 of this embodiment is a type in which the driver's seat 9 is not covered by a cabin. Therefore, the rope frame 12 is provided for the purpose of protecting the driver when the tractor 1 rolls over.

[0016] In the vehicle body 2, a transmission case 13 is located behind the engine 6 and below the driver's seat 7. More specifically, the transmission case 13 is located below the steering column 10. A power transmission device (not shown) is disposed inside the transmission case 13. The rotational power of the engine 5 is transmitted to at least one of the front wheels 3 and the rear wheels 4 via the power transmission device in the transmission case 13.

[0017] In the vehicle body 2, a dashboard 14 is disposed between the bonnet 5 and the steering column 10. Fig. 2 is a perspective view of the dashboard 14 as viewed from the rear. The dashboard 14 has a first cover 141 and a second cover 142. The first cover 141 is made of a metal such as SUS.

[0018] The second cover 142 is located at the upper rear end of the first cover 141. The second cover 142 is made of resin. Examples of the resin include ABS (acrylonitrile-butadiene-styrene copolymer synthetic resin), PP (polypropylene resin), PE (polyethylene resin), and PC (polycarbonate resin). A meter panel 142a showing a speedometer, a fuel gauge, a water temperature gauge, etc. is provided at the rear end of the second cover 142.

[0019] FIG. 3 is a perspective view showing a state in which the first cover 141 of the dashboard 14 shown in FIG. 2 has been removed. The tractor 1 is provided with a partition plate 20 which is a partition member. The partition plate 20 is a partition wall which separates the inside of the bonnet 5 from the inside of the dashboard 14. The partition plate 20 is made of a metal plate having a thickness of, for example, about 10 mm. The partition plate 20 is located between the bonnet 5 and the steering column 10, more specifically, between the engine 6 (see FIG. 1) inside the bonnet 5 and the steering column 10. As a result, the partition plate 20 blocks heat radiated rearward from the engine 6.

[0020] The tractor 1 includes a fuel tank 30. The fuel tank 30 is a container that stores fuel. The fuel in the fuel tank 30 is supplied to the engine 6 via a fuel hose by a feed pump 62 (see FIGS. 14 and 15) described below. The fuel tank 30 is located between the partition plate 20 and the steering column 10. The fuel tank 30 is supported by the partition plate 20 via a tank support portion 30a.

[0021] The fuel tank 30 has a fuel receiving section 90 which is connected to an oil leakage hose 91, the details of which will be described later.

[0022] A lid member 52, which will be described later, is located above the partition plate 20. Fig. 4 is a perspective view showing the inside of the dashboard 14 (see Fig. 2) with the lid member 52 of Fig. 3 removed. Inside the dashboard 14, a bonnet rotating part 40 is located below the lid member 52. Details of the bonnet rotating part 40 will be described below.

[0023] Fig. 5 is a perspective view showing the internal configuration of the bonnet 5 (see Fig. 2) and the dashboard 14. Fig. 6 is an enlarged perspective view of the bonnet rotation part 40 of Fig. 5. The bonnet rotation part 40 supports the bonnet 5 (see Fig. 4, etc.) so that it can rotate up and down. Such a bonnet rotation part 40 has a rotation shaft part 41, a support plate 42 which is a support member, a hinge 43, and a hinge stay 44.

[0024] The pivot shaft portion 41 is a portion that serves as a pivot shaft for the bonnet 5 and the hinges 43. The pivot shaft portion 41 is positioned extending in the left-right direction. The support plate 42 supports the bonnet 5 from the inside (the engine 6 side). Two hinges 43 are provided in the left-right direction. One end (front end) of each hinge 43 is fixed to the support plate 42. The other end (rear end) of each hinge 43 is fixed to both ends of the pivot shaft portion 41, respectively.

[0025] 7 is an enlarged perspective view of the hinge stay 44 of the bonnet rotation part 40. Both ends of the rotation shaft part 41 are rotatably supported by the hinge stays 44. The hinge stays 44 are fixed to the partition plate 20 via mounting stays (not shown). Therefore, the rotation shaft part 41 is rotatably supported by the partition plate 20 via the hinge stays 44 and the mounting stays.

[0026] 8 is a perspective view of the partition plate 20. The partition plate 20 has a notch 20a at its upper end. In this embodiment, two notches 20a are provided in the left and right directions of the upper end of the partition plate 20 corresponding to the two hinges 43. Each hinge 43 is positioned passing through the notch 20a of the partition plate 20 in the front-rear direction (see FIG. 5).

[0027] 5, in this embodiment, the rotation shaft portion 41 is located above the fuel tank 30 and between the partition plate 20 and the steering column 10. As a result, the rotation fulcrum when the bonnet 5 is rotated by the bonnet rotation portion 40 is located above the fuel tank 30 and between the partition plate 20 and the steering column 10. In other words, the rotation fulcrum is located above the fuel tank 30 and rearward of the partition plate 20.

[0028] Fig. 9 is a side view showing a schematic position (closed state) of the bonnet 5 before it is rotated. Fig. 10 is a side view showing a schematic position (open state) of the bonnet 5 after it is rotated. When the rotation shaft 41 is viewed from the side as in Figs. 9 and 10, the rotation center of the rotation shaft 41 is referred to as a rotation fulcrum F here.

[0029] By positioning the pivot point F above the fuel tank 30 and rearward of the partition plate 20, a larger open space can be secured when the bonnet 5 is rotated upward, compared to a configuration in which the pivot point F is located forward of the partition plate 20. In particular, the rear portion of the bonnet 5, i.e., the portion of the bonnet 5 close to the partition plate 20, can be opened widely. This improves the ease of operation when rotating the bonnet 5 for maintenance.

[0030] In particular, by positioning the pivot shaft portion 41 of the bonnet pivot portion 40 between the partition plate 20 and the steering column 10, a configuration can be reliably realized in which the pivot fulcrum F when the bonnet 5 pivots is positioned between the partition plate 20 and the steering column 10.

[0031] Furthermore, the hinge 43 of the bonnet rotating part 40 is positioned through the notch 20a at the upper end of the partition plate 20. This ensures that the configuration of this embodiment in which the rotating shaft part 41 to which the hinge 43, which is connected to the bonnet 5 via the support plate 42, is fixed is positioned between the partition plate 20 and the steering column 10 can be realized.

[0032] 4 and 5, the tractor 1 of this embodiment includes a hinge cover 51. The hinge cover 51 is fixed to the rear surface of the partition plate 20 (the surface on the steering column 10 side).

[0033] Fig. 11 is a perspective view of the hinge cover 51. Fig. 12 is a perspective view showing the hinge cover 51 attached to the partition plate 20. The hinge cover 51 is formed by bending a single flat plate. The hinge cover 51 has a first flat plate portion 51P, a second flat plate portion 51Q, a third flat plate portion 51R, and a fourth flat plate portion 51S.

[0034] The first flat plate portion 51P is a flat plate extending in the up-down and left-right directions. The first flat plate portion 51P is elongated in the left-right direction and has an opening 51b. A hinge for rotating a lid 95 (see FIG. 2) that opens and closes a fuel filler opening 92 (see FIG. 3) can be positioned in the opening 51b. This prevents the hinge from coming into contact with the hinge cover 51 when the lid 95 is opened or closed.

[0035] The second flat plate portion 51Q is a flat plate that is elongated in the left-right direction and is connected to the lower edge of the first flat plate portion 51P. The lower edge of the second flat plate portion 51Q is located forward of the first flat plate portion 51P. Therefore, the second flat plate portion 51Q forms an obtuse angle with the first flat plate portion 51P.

[0036] The second flat plate portion 51Q has a passage opening 51a. That is, the hinge cover 51 has the passage opening 51a. As shown in FIG. 12, a hose H or a harness E (hereinafter, referred to as a hose or the like) is inserted through the passage opening 51a. That is, the hose H or the like is positioned through the passage opening 51a of the hinge cover 51. Also, the hose H or the like that has passed through the passage opening 51a is positioned through the cutout portion 20a of the partition plate 20 (see FIG. 14). Note that the passage opening 51a of the hinge cover 51 is formed as a cutout portion in this embodiment, but may be formed as a hole. Also, a gap between the passage opening 51a and the hose H or the like is filled with a packing or the like. The hose H is a hose through which oil, water, fuel, or the like flows, but the fluid that flows through the hose H is not limited to these. The harness E is connected to, for example, an electrical component of the tractor 1.

[0037] In this way, by providing the passage opening 51a in the hinge cover 51 and arranging the hose H, etc., to pass through the passage opening 51a and the cutout portion 20a, it is possible to arrange the hose H, etc., without providing a separate passage opening in the partition plate 20 exclusively for passing the hose H, etc. Therefore, since the passage opening is not provided in the partition plate 20, the hot air of the engine 6 does not flow rearward (toward the steering column 10) through the passage opening. Furthermore, since the passage opening is not provided in the partition plate 20, it is also possible to avoid a decrease in the strength of the partition plate 20 due to the formation of the passage opening.

[0038] The third flat plate portion 51R is a flat plate extending in the front-rear and up-down directions, and is connected to the left edge of the first flat plate portion 51P. The lower edge of the third flat plate portion 51R is inclined downward toward the front. This allows the lower edge of the third flat plate portion 51R to contact the left edge of the second flat plate portion 51Q. The front end of the third flat plate portion 51R is bent outward to the left to form a fixed plate 51R1. Two through holes 51h are formed in the fixed plate 51R1 in a vertical line.

[0039] The fourth flat plate portion 51S is a flat plate extending in the front-rear and up-down directions, and is connected to the right edge of the first flat plate portion 51P. The lower edge of the fourth flat plate portion 51S is inclined downward toward the front. As a result, the lower edge of the fourth flat plate portion 51S contacts the right edge of the second flat plate portion 51Q. The front end of the fourth flat plate portion 51S is bent outward to the right to form a fixing plate 51S1. Two through holes 51h are formed in the fixing plate 51S1 in a vertical line.

[0040] 13 is a perspective view showing a process of attaching the hinge cover 51 to the partition plate 20. The hinge cover 51 is attached and fixed to the partition plate 20 by bolts or the like. Specifically, the fixing plates 51R1 and 51S1 are brought into surface contact with the partition plate 20 from the rear. In this state, bolts (not shown) are inserted into the through holes 51h of the fixing plates 51R1 and 51S1 and the passing holes 20b provided in the partition plate 20, respectively, and fastened with nuts (not shown). As a result, the hinge cover 51 is fixed to the partition plate 20.

[0041] 13, the hinge cover 51 covers the cutout portion 20a of the partition plate 20 from the rear, that is, from the steering column 10 side. Also, as shown in FIG.

[0042] Thus, in this embodiment, the hinge cover 51 simultaneously covers the cutout portion 20a and the rotating shaft portion 41 from the steering column 10 side. This allows the hinge cover 51 to block hot air from the engine 6 (see FIG. 1 ) that passes through the cutout portion 20a and attempts to flow toward the steering column 10 via the rotating shaft portion 41.

[0043] 3 to 5, the tractor 1 of this embodiment is provided with a cover member 52. The cover member 52 covers the pivot shaft portion 41 and the hinge cover 51 of the bonnet pivot portion 40 from above. The cover member 52 is made of, for example, a urethane cover, and extends in the left-right direction.

[0044] In this way, by covering the hinge cover 51 from above with the lid member 52, the space surrounded by the partition plate 20 and the hinge cover 51 (the space in which the rotating shaft portion 41 is located) can be almost sealed. Therefore, the hot air from the engine 6 passing through the cutout portion 20a of the partition plate 20 can be trapped and blocked by the hinge cover 51 and the lid member 52.

[0045] Fig. 14 is a perspective view showing the configuration of the lower right part of the fuel tank 30 in the tractor 1. The tractor 1 of this embodiment is equipped with a water separator 61 and a feed pump 62. The water separator 61 and the feed pump 62 are located in a fuel supply path X between the fuel tank 30 and the engine 6 (see Fig. 1). The water separator 61 removes (separates) moisture contained in the fuel supplied from the fuel tank 30. The feed pump 62 supplies the fuel in the fuel tank 30 to the engine 6 via the water separator 61.

[0046] The tractor 1 further includes a bracket 63. The bracket 63 is connected to a lower portion (particularly, the lower right portion) of the partition plate 20 by a bolt or the like. The bracket 63 supports the water separator 61 and the feed pump 62.

[0047] FIG. 15 is an exploded perspective view of the bracket 63, the water separator 61, and the feed pump 62. The bracket 63 has a support stay 63a, a pump fixing portion 63b, and a right partition wall portion 63c. The support stay 63a is a support member that supports the water separator 61 and is positioned to extend in the front-rear direction. The pump fixing portion 63b is a flat plate that is fixed to the front end portion of the support stay 63a. The feed pump 62 is fixed to the pump fixing portion 63b by bolts or the like. The right partition wall portion 63c is located on the lower right side of the partition plate 20, and separates the inside of the bonnet 5 from the inside of the dashboard 14, similar to the partition plate 20. The right partition wall portion 63c is formed in a substantially triangular shape when viewed from the front side in order to fill the vertical gap formed between the transmission case 13 and the partition plate 20. The right partition wall portion 63c is fixed to the support stay 63a by welding or bolts.

[0048] By connecting the bracket 63 to the lower part of the partition plate 20, the bracket 63 can be given not only the function of supporting the water separator 61 and the feed pump 62, but also the function of blocking hot air from the engine 6. In other words, the bracket 63 supporting the water separator 61 and the feed pump 62 can be effectively used as a member for blocking hot air.

[0049] In particular, the right partition wall portion 63c of the bracket 63 is formed in a shape that fills the gap between the transmission case 13 and the partition plate 20, and therefore the right partition wall portion 63c can be treated as a member that extends downward from the right-side lower end portion of the partition plate 20. Thus, the right partition wall portion 63c can be provided with the same hot air blocking function as the partition plate 20.

[0050] In this embodiment, as shown in Fig. 14, the left partition wall portion 64 is located below and to the left of the partition plate 20. The left partition wall portion 64 is fixed to the left lower end portion of the partition plate 20 by a bolt. The left partition wall portion 64 is formed in a shape that is approximately symmetrical to the right partition wall portion 63c in the left-right direction, and fills the gap between the transmission case 13 and the partition plate 20, similar to the right partition wall portion 63c. In this case, the left partition wall portion 64 can be treated as a member that extends downward from the left lower end portion of the partition plate 20. Therefore, the left partition wall portion 63c can be provided with the same hot air blocking function as the partition plate 20.

[0051] Fig. 16 is a perspective view of the above-mentioned fuel tank 30 as seen from the rear. Fig. 17 is a perspective view of the fuel tank 30 as seen from the front. The fuel tank 30 has a front surface portion 31 (see Fig. 17), a side surface portion 32, a top surface portion 33, a bottom surface portion 34, and a rear surface portion 35 (see Fig. 16).

[0052] The front surface portion 31 is located opposite the partition plate 20 (see FIG. 14, etc.) within the dashboard 14. The front surface portion 31 has a recess 31a. The recess 31a is configured as a groove extending in the vertical direction. Two recesses 31a are provided on the front surface portion 31. The two recesses 31a are provided side by side with a gap between them in the left-right direction.

[0053] The side surface portions 32 are located on the left and right sides of the front surface portion 31. The left and right side surface portions 32 are connected to the left and right edges of the front surface portion 31, respectively. This connects the left and right side surface portions 32 to the front surface portion 31. The top surface portion 33 is connected to the upper portion of the front surface portion 31 and the upper portions of the left and right side surface portions 32. This connects the top surface portion 33 to the front surface portion 31 and the left and right side surface portions 32.

[0054] The bottom surface portion 34 is connected to the lower part of the front surface portion 31 and the lower parts of the left and right side surface portions 32. This connects the bottom surface portion 34 to the front surface portion 31 and the side surface portions 32. As shown in FIG. 17, the bottom surface portion 34 has a shape in which the center part of the bottom surface is recessed toward the top surface portion 33, but the bottom surface portion 34 may be flush. The rear surface portion 35 is connected to the top surface portion 33, the left and right side surface portions 32, and the bottom surface portion 34.

[0055] FIG. 18 is a perspective view of the partition plate 20 as viewed from the rear. A reinforcing frame 21 is fixed to the rear surface of the partition plate 20, that is, the surface of the partition plate 20 on the steering column 10 side. That is, the tractor 1 includes the reinforcing frame 21 fixed to the partition plate 20. The reinforcing frame 21 extends in the vertical direction and is fixed to the partition plate 20 at two positions in the left and right directions. The reinforcing frame 21 is formed, for example, by bending a flat plate, but may be formed in a cylindrical shape (square tube) with a square cross section. The strength of the partition plate 20 can be increased by fixing the reinforcing frame 21 to the partition plate 20. The above-mentioned hinge cover 51 is attached to the upper part of the partition plate 20. The partition plate 20 is also fixed to the fixing plate 81 by welding or the like.

[0056] The reinforcing frame 21 has a passing portion 21a. The passing portion 21a is a portion through which the oil leakage hose 90 (see Figs. 3, 4, and 21) passes. Such a passing portion 21a can be configured as a recess (a groove extending in the vertical direction) formed by bending a flat plate that is the original plate of the reinforcing frame 21. When the reinforcing frame 21 is configured as a tube with a square cross section, the inside (hollow portion) of the tube can be used as the passing portion 21a.

[0057] A plurality of contact portions 22 are attached to the reinforcing frame 21. More specifically, a part (a protruding portion) of each contact portion 22 is fitted into a hole formed in the reinforcing frame 21 from the fuel tank 30 side, whereby each contact portion 22 is attached to the reinforcing frame 21.

[0058] Each contact portion 22 is made of an elastic material (for example, rubber). In this embodiment, two contact portions 22 are attached to one reinforcing frame 21 side by side in the vertical direction, but the number of contact portions 22 is not particularly limited.

[0059] Fig. 19 is a perspective view of the partition plate 20 with the fuel tank 30 supported by the tank support portion 30a, as viewed from the front. Fig. 20 is a perspective view showing the state of Fig. 19 with the partition plate 20 removed. Each reinforcing frame 21 is positioned in a recess 31a in the front surface portion 31 of the fuel tank 30. At this time, the contact portion 22 attached to the reinforcing frame 21 comes into contact with the front surface portion 31 (particularly the portion facing each other in the recess 31a).

[0060] By positioning the reinforcing frame 21 in the recess 31 a of the front portion 31 , the fuel tank 30 is appropriately positioned relative to the partition plate 20 .

[0061] 20 , the bottom portion 34 of the fuel tank 30 is supported by a fixed plate 81 via a support member 82. A spacer 83 is positioned between the fixed plate 81 and the transmission case 13. Therefore, the bottom portion 34 of the fuel tank 30 is supported by the transmission case 13 via the support member 82, the fixed plate 81, and the spacer 83.

[0062] In this embodiment, the fuel that leaks when the fuel tank 30 is filled with fuel (hereinafter, also referred to as leaked oil) is configured to be discharged to the outside of the tractor 1. Hereinafter, a structure for discharging the leaked oil will be described.

[0063] As shown in Fig. 19, the fuel tank 30 has a fuel receiving portion 90. The fuel receiving portion 90 is provided on the upper surface portion 33 of the fuel tank 30. Fig. 21 is a side view of the fuel tank 30. Note that, for the sake of convenience, the support structure of the fuel tank 30 (tank support portion 30a in Fig. 19) is not shown in Fig. 21.

[0064] The fuel receiving portion 90 has a fuel filler opening 92 and a fuel receiving tray portion 93. Fuel is poured into the fuel tank 30 through the fuel filler opening 92. The fuel receiving tray portion 93 is located around the fuel filler opening 92. The fuel receiving tray portion 93 receives fuel (leakage oil) that spills to the outside from the fuel filler opening 92 during refueling.

[0065] 21, a leakage hose 91 is connected to the bottom of the fuel receiving tray portion 93. The leakage hose 91 is positioned passing through the passing portion 21a of the reinforcing frame 21, and extends to below the fuel tank 30.

[0066] In this way, the leakage hose 91 connected to the fuel receiving tray 93 passes through the passage 21a of the reinforcing frame 21, so that the leakage oil that has spilled around the fuel filler port 92 and is received by the fuel receiving tray 93 is discharged downward through the leakage oil hose 91. This reduces inconveniences caused by oil leakage during refueling (for example, situations in which surrounding electrical components come into contact with the fuel and malfunction). In addition, the inside of the reinforcing frame 21 (passage 21a) can be effectively used as a passage for the leakage hose 91, and the leakage hose 91 can also be protected by the reinforcing frame 21.

[0067] Although the embodiment of the present invention has been described above, the scope of the present invention is not limited to this, and the invention can be expanded or modified without departing from the spirit of the invention. [Industrial Applicability]

[0068] The present invention can be used in work vehicles such as tractors. [Explanation of symbols]
