Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid storage tank that can be moved back and forth in a mobile vehicle.

For agricultural tractors, etc., a liquid storage tank for separate work is suspended at the front end and rear end of the body by a vertically movable link via a link, and the liquid storage tank itself is divided into two types. There is a vehicle in which the wheels and the towing rod are mounted and one end of the towing rod is attached to the body to travel. In the present invention, a liquid storage tank is used as a part of the body.

[Prior Art] As described above, in the related art, a liquid storage tank is suspended vertically by a lifting link such as a two-point link or a three-point link provided at the front and rear ends of the body. There are two types, one that travels substantially integrally with the body and the other that has another wheel and a tow rod attached to the liquid storage tank itself, and one end of the tow rod is attached to the body to tow and travel separately from the body.

[Problem to be Solved by the Invention] In such a conventional device, when the body and the link are attached substantially integrally, the total length is lengthened by an amount corresponding to the overhang of the rear portion, and the protruding portion of the rear portion when turning in a narrow place is reduced. It is easy to come into contact with other things, and driving becomes difficult compared to a wide place without other things.

In addition, the one that is attached to one end of the towing rod and towed separately from the fuselage can bend even at a narrow place because it bends at the towed rod portion. As mentioned above, as another towing license is required, it is very difficult to drive backwards compared to driving forward,
Requires long experience days of driving.

[Means for Solving the Problems] The present invention is to solve such a problem of the conventional device, and has taken the following technical means. That is, the front and rear wheels 8, 9 are provided in the front and rear of the body, at least the rear part of the body is a substantially flat machine frame 4 in the front and rear direction, and the storage tank 1 is arranged in the front and rear direction from above the rear wheels 9 to the rear end of the body. The rear tank of the fuselage is arranged around the entire width of the fuselage. The storage tank 1 stores liquid therein and has a seating portion 2 for a driver at the upper front and a rear portion protrudes from the rear end of the fuselage. In addition, a front-rear direction guide 3 is provided on the bottom surface of the storage tank 1 and a front-rear direction
And the guide portion 3 of the storage tank 1 is engaged with the guide 5, and the liquid pump 6 is mounted in the lower tank width near the bottom surface of the storage tank 1 so as to project rearward from the machine frame 4 at the rear end of the body. The storage tank 1 can be adjusted to move back and forth along the guide tool 5. When the storage tank 1 is adjusted to move backward, the upper part of the liquid pump 6 is covered by the rear portion of the storage tank 1, and when the storage tank 1 is moved to the forefront side, , Liquid pump 6 attached to machine frame 4
The liquid storage tank is movable forward and backward of a mobile vehicle, characterized in that the liquid storage tank appears outside.

[Effects of the Invention] The present invention has the following technical effects by the above configuration. That is, the front and rear wheels 8, 9 are provided in the front and rear of the body, at least the rear part of the body is a substantially flat machine frame 4 in the front and rear direction, and the storage tank 1 is arranged in the front and rear direction from above the rear wheels 9 to the rear end of the body in the width direction. Is a tank in the rear half of the fuselage, which is arranged around the entire width of the fuselage. Therefore, the storage tank 1 can be arranged as a configuration having a large capacity at the rear of the fuselage. Therefore, the driver's seat 2 can be easily provided in the upper front portion of the storage tank 1.

Further, the front and rear direction guides 3 are provided on the bottom surface of the storage tank 1 and the front and rear direction guides 5 are provided on the machine frame 4, and the guides 3 of the storage tank 1 are engaged with the guides 5. Even if the storage tank 1 has a large capacity and the weight is increased, it is easy to adjust the movement in the front-rear direction and the seat 2 is adjusted in the front-rear direction in accordance with the length of the driver's foot to facilitate driving. Can be held.

Further, since the liquid pump 6 is mounted in the width of the tank below the bottom surface of the storage tank 1 and protruding rearward from the machine frame 4 at the rear end of the body, the working machine that moves the storage tank 1 rearward is adjusted. When the vehicle is traveling, the upper side and the left and right sides of the liquid pump 6 can be protected by the trailing edge and the left and right side edges of the storage tank 1, and the traveling of the liquid pump 6 is less likely to come into contact with other objects during traveling. At the time of inspection and maintenance, the storage tank 1 is moved to the frontmost
Since the liquid pump 6 attached to the rear end is exposed to the outside, the weight of the storage tank 1 is adjusted by the guide portion 3 of the storage tank 1 and the guide 5 on the side of the machine frame 4 so that the weight can move in the direction between the front and rear wheels 8 and 9. , So even if the storage tank 1 is large enough to occupy the rear half of the fuselage, there is little danger of the aircraft being lost in front and rear and left and right balance due to movement during inspection and maintenance of the storage tank 1, and It is not necessary to reduce the amount of liquid in the storage tank 1 at the time of maintenance of the liquid pump 6, and the strength of the liquid pump 6 can be maintained without increasing the size of the guide 5 because it is not a cantilevered guide. Since the rear portion and the left and right side portions are opened to the rear of the machine, the operator can directly approach the liquid pump 6 without taking an unreasonable posture such as peeping or twisting the body, thereby improving maintainability.
