Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a walking type management machine in which a worker performs a maneuvering operation while walking on the rear side of a machine body in a working machine used for farming work in a field.
[0002]
[Prior art]
As is well known in the past, the walking type management machine is equipped with a running wheel and a rotary on the lower part of the fuselage, an engine is mounted on the upper front side of the fuselage, and a steering wheel is directed diagonally upward from the upper center of the fuselage. Standing up, the operator holds the rear end of the handlebar to perform the steering operation.
[0003]
[Problems to be solved by the invention]
As described above, the walking-type management machine allows the operator to operate while walking on the rear side of the aircraft, so that the lower front part of the aircraft is easier to see the unevenness of the ground just before the aircraft, and it is easier to operate. As described above, since the engine is mounted on the front of the airframe and the fuel tank is mounted on the engine, the ground clearance is increased.
[0004]
[Means for Solving the Problems]
Therefore, in the present invention, the traveling wheel 3 is provided at the lower part of the gear case 2 provided in the center of the airframe 1, the rotary 4 is provided on the rear side thereof, the engine 5 is mounted on the front side of the gear case 2, and obliquely rearward from the upper side of the gear case 2. In a walking type management machine in which a steering wheel 6 is provided and an operator walking on the rear side of the machine body 1 controls the steering wheel 6 with the rear end portion of the steering wheel 6, it is moved forward and backward from the rear upper part of the engine 5 to the lower part of the base of the steering wheel 6. A long fuel tank 7 is provided, and the fuel tank 7 is configured to supply fuel to the engine 5 from a reservoir 8 formed at the front lower portion of the fuel tank 7, and a front reservoir 8 and a rear reservoir 50 of the fuel tank 7 are provided. When the rotary 4 is lifted up, the fuel moves from the rear reservoir 50 to the front reservoir 8, and the fuel in the front reservoir 8 remains at the rear when the machine body 1 is leveled or plowed. Move to reservoir 50 It was prevented by consisting of a walking type management machine configuration from.
Further, a rear reservoir 50 having a larger capacity than the front reservoir 8 is formed in the rear lower portion of the fuel tank 7.
[0005]
[Action and effect of the invention]
With the above configuration, there is no fuel tank 7 on the engine 5 at the front of the fuselage, and by providing the fuel tank 7 that is formed long in the front and back from the rear side of the engine 5 to the lower part of the base of the handle rod 6, the fuel capacity can be reduced. While sufficient, the front part of the aircraft can be lowered, and it becomes easier for the operator to operate while walking the rear part of the aircraft.
Although the weight of the fuel tank 7 is reduced, the weight is reduced. However, since the fuel tank 7 is provided below the base of the handle bar 6 located substantially at the center of the airframe, the balance between the front and rear of the airframe due to the reduction of fuel is achieved. The maneuverability is good without changing.
Further, by forming a rear reservoir 50 having a capacity larger than that of the front reservoir 8 at the rear lower portion of the fuel tank 7, the rear side of the base portion of the handle bar 6 is not increased without raising the fuel tank 7 upward. The space can be used to increase the tank capacity. The fuel collected in the rear reservoir 50 moves to the front reservoir 8 when the rotary 4 is lifted to turn the management machine, and does not hinder the use.
In addition, by providing a weir between the front reservoir 8 and the rear reservoir 50 of the fuel tank 7, the fuel in the front reservoir 8 is prevented from moving to the rear reservoir 50 during work, and the fuel runs out. To prevent becoming.

【Example】
Next, an embodiment of the present invention will be described with reference to the drawings.
The gear case 2 provided in the center of the machine body 1 distributes the rotation of the input shaft for inputting power from the engine 5 to the travel output shaft for outputting power to the traveling wheels 3 and the rotary output shaft for outputting power to the rotary 4. In addition, a transmission mechanism that rotates in high, low, and reverse directions and a rotary clutch that intermittently transmits power to the rotary output shaft are provided, and a traveling transmission case 16 is attached downward from the gear case 2 to the lower end of the case 16. A single traveling wheel 3 is attached, a rotary transmission case 17 is attached to the rear lower side, and a tilling blade 19 is attached to an output shaft 18 projecting left and right at the lower end of the case 17 to constitute the rotary 4.
[0007]
An attachment frame 21 for attaching a rotary cover 20 covering the upper portion of the rotary 4 so that the front and rear positions can be changed is attached to the gear case 2 at the upper part of the rotary 4, and a resistance rod 22 for determining the tilling depth is provided at the rear end of the attachment frame 21. It is attached.
An engine mounting base 23 projects from the front of the gear case 2, the engine 5 is mounted on the mounting base 23, and power is transmitted by belt transmission between the output shaft of the engine 5 and the input shaft of the gear case 2. . A cover 24 covers the belt transmission mechanism.
As shown in FIG. 4, a long fuel tank 7 is attached from the rear of the engine 5 to the top of the gear case 2 in the front-rear direction. A front reservoir 8 that is recessed downward is formed at the front lower portion of the fuel tank 7, a rear reservoir 50 having a large capacity is formed at the rear, and a weir 52 is formed between the reservoirs 8 and 50. The fuel accumulated in the rear reservoir 50 of the fuel tank 7 by the vertical movement of the airframe 1 moves over the weir 52 and moves to the front reservoir 8. A pipe 25 is connected to an extraction pipe provided at the bottom of the front reservoir 8 so that fuel is supplied to the engine 5. Reference numeral 26 denotes a supply plug of the fuel tank 7.
