Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an auxiliary leg mounting device for a grain transport tank which transports grains and the like mounted on a truck or the like.

[0002]

2. Description of the Related Art When a grain transport tank is mounted on a truck bed, there is known a method in which auxiliary legs are attached and lifted to a predetermined height, and the truck is moved backward to load the grain. For example, Japanese Utility Model Laid-Open No. 60-167797 is known.

[0003]

However, according to the above-mentioned known technique, a leg support cylinder is provided in the front and rear of the bottom frame in the width direction to slide the legs. In this case, the weight of the transport tank itself is applied to the inner lateral surface of the support cylinder, and there is a disadvantage that it takes a great deal of labor to pull out each leg. Also,
No. 151310 discloses a view of folding down in the direction along the support leg surface, but there is no fixing means at the time of storage and use, and it is unstable.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a grain transport tank having auxiliary legs provided on both sides of a frame. A horizontal arm is provided on the upper part of the supporting leg and the supporting leg, and a vertical boss is provided at the tip of the horizontal arm to constitute an auxiliary leg, and the boss of the auxiliary leg is rotatably attached to the vertical axis, When the auxiliary leg is folded and stored when not in use, the auxiliary leg is expanded by pulling in when used, and a hole provided in the vertical axis and the boss in a horizontal direction is selected and fixed by a pin. An auxiliary leg mounting device for a grain transport tank is provided.

[0005]

As described above, the boss at the base of the auxiliary leg having the lateral arm protruding outward is provided rotatably on the vertical axis provided on the side frame of the grain tank. The support leg having the caster can be easily folded while moving along the side frame by simply pressing the lightly. What is necessary is just to fix by pin replacement suitably.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration will be described with reference to the drawings embodying the present invention. FIG. 1 is an overall perspective view embodying the present invention, FIG. 2 is an enlarged perspective view of a main part, and FIG.

[0007] Reference numeral 1 denotes a grain tank, which is equipped with a well-known screw conveyor, and 7 denotes a discharge port thereof. Reference numeral 2 denotes a side frame, which is a support frame material for the grain tank 1.
Reference numeral 8 denotes a shutter lever for opening and closing the shutter of the grain in the grain tank. Reference numeral 3 denotes an auxiliary leg, which is provided with a vertical boss 5 at the end of a horizontal arm 9. Reference numeral 4 denotes a vertical axis vertically mounted on the side frame 2 and rotatably supports the boss 5 described above. 6 is a caster.

FIG. 2 is a detailed view of the auxiliary leg portion, in which the boss 5 is inserted into the longitudinal axis 4 and abuts on the receiving shaft 11 to rotate. Reference numeral 10 denotes a pin which is fixed to the grain tank 1 at a position protruding in the width direction and at a folded position. The height of the support leg 8 is changed by replacing the pin 10 '. The 10 ″ pin may be removed when the longitudinal axis 4 is disassembled and removed from the side frame 2.

FIG. 3 is a plan view of a section showing the operation of the auxiliary leg 3 in a folded state. When the pin 10 is removed and the grain tank 1 is pressed lightly, the grain tank 1 can be folded along the side frame 2. Therefore, when not in use, it is folded and stored, and when in use, it is pulled out to expand the auxiliary portion 3, and the holes 12 and 12 ′ are appropriately selected and fixed by the pins 10.

[0010]

As described above, when the grain tank is stored, it can be easily folded when stored, and when used, it can be easily spread on the truck bed by moving it lightly, which is convenient.
