[0003]

[Problems to be solved by the device]

 In the conventional small-sized shovel, a floor plate portion (a portion indicated by a in FIG. 4) is set so as to be able to move up and down with respect to a driver's seat from both left and right sides of a front portion of an upper swing body. Because of this, the size of the fuel tank and hydraulic oil tank was limited, so the tank capacity of the fuel tank was small. Therefore, when operating a small shovel, it is necessary to refuel the fuel in a short time, which may hinder the progress of work. Also, because the fuel tank is fixed and installed so that it cannot be moved, the space utilization of the upper revolving structure under the fuel tank was not sufficient, and the layout or maintenance of the parts of the small excavator was not good. . An object of the present invention is to provide a tank device that can solve the above problems.

[0004]

[Means for Solving the Problems]

 In the tank device of the present invention, the tank is rotatably arranged in the front part of the upper revolving structure of the small excavator so as to be horizontally and horizontally outwardly, and the storage of the battery, tools, etc. is provided below the position where the tank is arranged. It was configured with a space for use. Alternatively, in the front of the upper revolving structure of the small excavator, the tank is arranged so that it can be tilted and rotated in the vertical direction, and a storage space for batteries, tools, etc. is provided below the position where the tank is arranged.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a main part of a notch showing a revolving superstructure 8 of a small excavator (not shown in general view of the small excavator) equipped with a tank device 7 according to claim 1 of the present invention. In the figure, 9 is a fuel tank which is a tank, 10 is a hydraulic oil tank, 11 is a hinge member which hinges the fuel tank 9 to the hydraulic oil tank 10, and 12 is the fuel tank 9 with respect to the upper swing body 8. Bolts, locking metal fittings such as catch fittings, 13 is a grip portion, 14 is a driver's seat, 15 is a battery, and 16 is a tool box for maintenance. FIG. 2 is a perspective view of essential parts showing an embodiment of the tank device 7 in FIG. In the figure, 17 is a flexible hose connected from a fuel tank 9 to an engine (not shown).

Next, the configuration of the tank device 7 according to claim 1 of the present invention will be described with reference to FIGS. 1 and 2. In the tank device 7, the fuel tank 9 is directed to the outer side in the horizontal direction in the front part of the upper revolving structure 8 of the small shovel (toward the outer side as indicated by the arrow B in FIG. The fuel tank 9 is arranged so as to be rotatable, and a storage space for the battery 15, tools and the like (a space designated by reference numeral 18 in FIG. 2) is provided below the fuel tank 9.

Next, the operation of the tank device 7 according to claim 1 of the present invention will be described. When the small shovel does not perform maintenance work such as repair and inspection, the fuel tank 9 is fixed to the upper revolving structure 8 by the locking metal fitting 12, as shown in FIG. Moreover, the battery 15, the tool box 16 and the like are housed in the storage space 18 of the upper revolving structure 8 below the fuel tank 9. Next, when inspecting the battery (15) of the small shovel, or taking out tools, etc., loosen and remove the locking metal fitting 12, and turn it outward with the hinge member 11 as the center of rotation (in the direction of arrow B shown in FIG. 2). ), And rotate it manually. Since the storage space 18 is opened, the battery can be inspected or tools can be taken out. In the tank device 7 of the present invention, it is not possible to move up and down with respect to the driver's seat 14 from the side where the fuel tank 9 is arranged. However, the tank capacities of the fuel tank (9) and the hydraulic oil tank (10), which are the object of the invention, can be greatly increased, and the storage space 18 under the fuel tank (9) can be used effectively. can do.

Next, FIG. 3 is a side view of an essential part of the tank device 19 according to claim 2 of the present invention. In the figure, the same components as those of the tank device 7 according to claim 1 of the present invention are designated by the same reference numerals. 8'is an upper swing body, 10 'is a hydraulic oil tank, 20 is a fuel tank, 21 is a hinge member that hinges the fuel tank 20 to the hydraulic oil tank 10', and 22 is a handle. Next, the configuration of the tank device 19 according to claim 2 of the present invention will be described with reference to FIG. In the tank device 19, a fuel tank 20 is arranged in a vertical direction (in the direction of arrow C) in a front portion of an upper revolving structure 8 ′ of a small excavator so that the fuel tank 20 can be tilted and rotated by a hinge member 21. A storage space 18 'for the battery 15, tools, etc., is provided below the position where the battery is placed.

Next, the operation of the tank device 19 according to claim 2 of the present invention will be described. When the small shovel does not perform maintenance work such as repair and inspection, the fuel tank 20 is fixed to the upper revolving structure 8 ′ by the locking metal fitting 12 as shown in FIG. 3. However, the storage space 18 'of the upper revolving structure 8'in the lower part of the fuel tank 20 accommodates the battery 15, the tool box 16 and the like. Next, when inspecting the battery (15) of the small shovel or taking out a tool or the like, the locking metal fitting 12 is loosened and removed, and the hinge member 21 is manually rotated upward with respect to the rotation center. The storage space 18 'is opened by locking and locking the fuel tank 20 at the position indicated by the phantom line (lock locking metal fittings are not shown), so that the battery can be checked or tools can be taken out. It can be performed. The function of the tank device 19 of claim 2 is the same as that of the tank device 7 of claim 1.

EFFECTS OF THE INVENTION In the conventional small-sized shovel, the capacity of the fuel tank is small because it is possible to move up and down with respect to the driver's seat from both left and right sides of the front part of the upper swing body. Therefore, during operation, refueling is performed within a short time, which may hinder work progress. Moreover, since the fuel tank is mounted so that it cannot be moved, the space utilization of the upper revolving structure under the fuel tank was not sufficient. However, in the tank device of the present invention, the fuel tank is arranged in the front part of the upper revolving structure of the small excavator so that the fuel tank can be rotated in the horizontal direction toward the outside or the fuel tank can be tilted and rotated in the vertical direction. The storage space for batteries, tools, etc. was provided under the fuel tank. Therefore, when inspecting the battery of a small shovel or taking out a tool, loosen the metal fittings that hold the fuel tank and remove it, and manually rotate the fuel tank to the left and right outside or upward. Since the storage space for the upper revolving structure at the bottom of the fuel tank position is opened, the battery can be checked and tools can be taken out. Therefore, in the construction machine equipped with the tank device of the present invention, the capacity of the fuel tank and the hydraulic oil tank can be greatly increased, and the storage space under the fuel tank can be fully utilized effectively.
