Detailed Description
Embodiments according to the present invention will be described in detail below with reference to the drawings.
Fig. 1 is a view showing a tractor in which a diesel engine E is mounted in a hood 2 in the front of a traveling vehicle body 1, and the rotational power of the engine E is transmitted to a transmission in a transmission case 3, and the rotational power decelerated by the transmission is transmitted to front wheels 4 and rear wheels 5. A steering wheel 6 for steering the front wheels 4, 4 is attached to the rear of the engine E, and a driver's seat 7 is provided behind the steering wheel 6. A hydraulic cylinder housing 8 is provided at the rear upper portion of the transmission case 3, and lift arms 9 constituting a part of the hydraulic lift mechanism are rotatably attached to the left and right sides of the hydraulic cylinder housing 8. The lifting arm 9 moves up and down by the telescopic operation of the lifting hydraulic cylinder 10. A three-point link mechanism including an upper link 11 and left and right lower links 12 is provided at the rear of the vehicle body, and a rotary work implement R is attached to the link mechanism, and the lower links 12 are connected to the lift arm 9 via lift levers 13 so that the work implement R can be lifted.
The steering wheel 6, the driver's seat 7, etc. are covered with a cockpit 16. The cabin 16 is fixed to the machine body via an elastic member such as vibration-proof rubber, so that vibration of the machine body is hard to transmit to the cabin.
The cockpit 16 is formed into an integrated frame structure by a floor 17, front pillars 16a erected on the left and right front portions of the floor 17, rear pillars 16b erected on the middle portions of the left and right fenders 18, and an upper frame 16c connecting the upper ends of these pillars to each other, and the frame structure is covered with a roof portion 16 d.
Fuel tanks 20 formed of a resin material are disposed on the left and right sides of the transmission case 3. That is, as shown in fig. 2 to 6, the fuel tank 20 is made of a resin material and is manufactured by blow molding, and the fuel tank 20 is disposed on the left and right sides of the transmission case 3. The tank capacity of the 1 st fuel tank 20L on the left and right sides is made smaller than the capacity of the 2 nd fuel tank 20R on the other left and right sides. The 1 st fuel tank 20L is formed so as to be close to a main body 20La of the transmission case 3 and an extension 20Lb located outside, the bottom of the main body 20La is supported by a 1 st support plate 21 connected to the transmission case 3, and the extension 20Lb is supported by a 2 nd support plate 22 fixedly connected to the 1 st support plate 21.
A urea tank 23 of a urea SCR system is disposed immediately in front of the 1 st fuel tank 20L. The support plate 24 supporting the lower portion of the urea tank 23 is supported by the transmission case 3, and the support plate 24 of the urea tank is coupled to the 2 nd support plate 22 of the 1 st fuel tank 20L to share and bear the load of the fuel tank 20L.
Regarding the support structure of the 1 st fuel tank 20L, the extension portion 20Lb is supported by the strip plate 25L. The cabin supporting bracket 39L and the auxiliary bracket 40L are provided in a state of protruding leftward and rightward from the transmission case 3, and the belt plate 25L is suspended and supported on the distal end sides of these brackets.
Further, since the 1 st fuel tank 20L is molded into the main body 20La and the extension portion 20Lb by blow molding of a resin, the extension portion 20Lb is formed with the fuel supply port 20a as a fuel supply portion, and the fuel supply cap 27 is detachably attached thereto.
Next, the other 2 nd fuel tank 20R is molded into a main body 20Ra and an extension 20Rb, but the support plate 28 for supporting the 2 nd fuel tank 20R at the bottom of the tank is formed into a plate frame formed by connecting front and rear gate steels, and the support plate 28 is fixed to the side wall or bottom wall of the transmission case 3 side via brackets 29a and 29b, whereby the 2 nd fuel tank 20R is supported. A fuel supply port 30a is formed at a front lower position on the 2 nd fuel tank 20R side, and one end of a fuel supply pipe 30 is connected to the fuel supply port 30a, and the other end of the fuel supply pipe 30 for supplying fuel to the engine E via a fuel pump not shown is connected to the engine E.
In the arrangement relation between the 1 st fuel tank 20L and the 2 nd fuel tank 20R, the front end of each tank is arranged such that the 2 nd fuel tank 20R side having a large capacity is located forward, the 1 st fuel tank 20L side having a small capacity is located rearward, and the arrangement relation with the urea tank 23 is also located rearward. On the other hand, the relation between the rear ends of the tanks is such that the rear end of the 1 st fuel tank 20L is located in front of the rear end of the 2 nd fuel tank 20R.
The 1 st fuel tank 20L and the 2 nd fuel tank 20R are attached to the transmission case 3 such that the bottom surfaces thereof are different in height, and the bottom surface of the 1 st fuel tank 20L is provided higher than the bottom surface of the 2 nd fuel tank 20R.
As described above, since the fuel supply port 20a is provided on the 1 st fuel tank 20L side, the 1 st fuel tank 20L and the 2 nd fuel tank 20R are connected together by the resinous communication pipe 31. That is, the communication pipe 31, one end of which is connected to the front lower portion inside of the 1 st fuel tank 20L, is formed in a straight line with substantially the same diameter, but a1 st bent portion 31a, a 2 nd bent portion 31b, and a 3 rd bent portion 31c in a crank shape for forming a gentle slope are formed midway. The other end of the communication pipe 31 is connected to the inside of the front lower portion of the 2 nd fuel tank 20R.
A branch pipe portion 31d is provided, and the branch pipe portion 31d branches from a portion near the 1 st fuel tank 20L in the vicinity of the 3 rd bent portion 31c and is connected to the front middle portion of the 2 nd fuel tank 20R. As described above, since the bottom surfaces of the 1 st fuel tank 20L and the 2 nd fuel tank 20R are set to be different in height from the ground and the connection portion of the communicating pipe 31 is made to be along the bottom surface, the connection portion 31A of the 1 st fuel tank 20L and the communicating pipe 31 is set to be higher than the connection portion 31B of the 2 nd fuel tank 20R and the communicating pipe 31 by the height H1, and the connection portion 31C of the 2 nd fuel tank 20R and the branch pipe portion 31d is set to be higher than the connection portion 31B of the 2 nd fuel tank 20R and the communicating pipe 31 by the height H2, as shown in fig. 5. The height H2 is set to be larger than the height H1.
The fuel supply port 30a of the 2 nd fuel tank 20R connected to the fuel supply pipe 30 for supplying fuel to the engine E is connected to the lowest position of the 2 nd fuel tank 20R.
Next, a check valve 32 is provided between the 3 rd bent portion 31c of the communication pipe 31 and the 2 nd fuel tank 20R, in other words, on the side of the 2 nd fuel tank 20R than the midway portion between the communication pipe 31 and the branch pipe portion 31 d. The check valve 32 is configured to allow fuel to flow from the 1 st fuel tank 20L to the 2 nd fuel tank 20R by using a film-like valve body shown in fig. 8 of patent document 2, for example, but can prevent fuel from flowing from the 2 nd fuel tank 20R to the 1 st fuel tank 20L in the reverse direction.
When the filler cap 27 in the fuel tank 20 configured as described above is removed and fuel (light oil) is injected from the filler hole 20a, the fuel first enters the 1 st fuel tank 20L and also enters the 2 nd fuel tank 20R via the communicating pipe 31 and the check valve 32 in the communicating pipe 31. When the fuel amount gradually increases, the fuel flows into the 2 nd fuel tank 20R from the connection portion 31B of the communication pipe 31 and the connection portion 31C of the branch pipe portion 31d, and the fuel amount of the 2 nd fuel tank 20R also increases.
While fuel is consumed by the operation of the engine E, when the vehicle body 1 is tilted left and right while traveling, fuel can be kept balanced left and right while reciprocating between the 1 st fuel tank 20L and the 2 nd fuel tank 20R via the communicating pipe 31. Specifically, when the traveling vehicle body 1 is tilted so that the 2 nd fuel tank 20R side is raised in a state where the fuel amount exceeds the connection portion 31C of the branch pipe portion 31d of the 2 nd fuel tank 20R, the fuel can flow so as to return to the 1 st fuel tank 20L side via the branch pipe portion 31d, but the backflow of the fuel from the connection portion 31B of the 2 nd fuel tank 20R to the 1 st fuel tank 20L is prevented due to the presence of the check valve 32. When the fuel amount is equal to or less than the connection portion 31C of the branch pipe portion 31d of the 2 nd fuel tank 20R in the horizontal posture, even if the 2 nd fuel tank 20R side becomes high, the fuel cannot exceed the connection portion 31C, and therefore, the fuel cannot flow back to the 1 st fuel tank 20L side.
When the 1 st fuel tank 20L is higher, even a small amount of fuel flows out of the connection portion 31B through the check valve 32 of the communication pipe 31 and flows into the fuel tank 20L. Further, since the connecting portion 31B of the 2 nd fuel tank 20R is lower than the connecting portion 31A of the 1 st fuel tank 20L by the height H1, a small amount of surplus fuel can be moved to the 2 nd fuel tank 20R side entirely.
The fuel supplied to the engine E is supplied to the engine E from the fuel supply pipe 30 connected to the 2 nd fuel tank 20R, but the fuel supply pipe 30 is configured to be supplied with the fuel from the fuel supply port 30a formed as much as possible in the bottom of the 2 nd fuel tank 20R, so that the remaining amount of the fuel can be reduced.
The upper parts of the 1 st fuel tank 20L and the 2 nd fuel tank 20R are connected by a vent connection pipe 33, and a small-diameter vent pipe 34 for opening the upper end part to the atmosphere is provided in one fuel tank (in the figure, the 2 nd fuel tank 20R having a large capacity) or in both fuel tanks.
A fuel sensor 35 is disposed on the 2 nd fuel tank 20R side to which the fuel supply pipe 30 is connected. The form of the fuel sensor 35 may be any of known forms, and for example, a stroke sensor may be used, but a position where the inclination of the traveling vehicle body 1 changes relatively little may be selected and set.
The extension portions 20Lb and 20Rb of the 1 st fuel tank 20L and the 2 nd fuel tank 20R are formed in a stepped shape, and constitute support portions for the upper and lower steps 38L and 38R. That is, as described above, the cabin support brackets 39L and 39R and the auxiliary brackets 40L and 40R are provided in a state of extending laterally from the transmission case 3, and the upper and lower steps 38L and 38R made of iron plates are supported on the distal end sides of these brackets. Since the lower steps 38L, 38R are arranged, step support portions are formed in the extension portions 20Lb, 20Rb of the 1 st fuel tank 20L, the 2 nd fuel tank 20R. The cockpit support brackets 39L and 39R and the auxiliary brackets 40L and 40R serve as support structures for the fuel tanks 20L and 20R.
In the figure, reference numeral 41 denotes a fuel filter existing in the middle of the fuel supply pipe 30, reference numeral 42 denotes an SCR system, and reference numeral 43 denotes a toolbox.
