Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid transport container, and more particularly to a liquid transport container that is mounted on a hand truck and used.

BACKGROUND OF THE INVENTION Hand trucks used for agricultural or civil engineering and construction work are known.

In order to adapt to relatively narrow usage environments, these transport vehicles often take the form of small wheeled vehicles with wheels at the front and legs for grounding at the rear, and usually the wheels and legs are fixed. A cargo loading area is formed on the frame.

For example, a loading tray as shown by the number 11 in the drawing is commonly used as a loading area for carrying earth, sand, and cement.

It can be well adapted to transporting solid materials such as compost.

However, these transport vehicles are not equipped with means for loading liquid materials such as water, liquid agricultural chemicals, and liquid fertilizers, and a separately prepared liquid transport container must be used when transporting liquid materials.

Therefore, the liquid transport container used on such a hand truck must be designed with due consideration given to stability when the truck is running, perspiration resistance when loading and unloading the contents, etc. However, no existing liquid transport container has yet been found that can satisfy these practical requirements.

The main object of the present invention is to find a new structure for a liquid transport container that overcomes the above-mentioned unresolved drawbacks of conventional liquid transport containers.

Another main objective of the present invention is to find new technical means to increase the capacity of the liquid transport container as much as possible while maintaining good running stability and operability.

Therefore, these objects of the present invention are such that the wheels 1 are attached to the frame 16.
A liquid transport container 20 is used by being mounted on a transport vehicle 10 having fixed legs 8 and legs 14. With the legs 14 in contact with the ground, the bottom wall surface 26 slopes downward from the front to the rear, and the front wall surface 24 located above or in front of the fixed position of the wheel 18 slopes downward from the front to the rear. This is preferably achieved by using a liquid conveying container 20 which is inclined downwardly at a larger angle of inclination than the above, and which is provided with an opening 28 with a cap at the rear of the upper wall surface 22 for entering and exiting the contents. I can do that.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a side view showing a liquid transport container 20 mounted on a unicycle-type handcart 10 with the legs of the cart in contact with the ground.

In FIG. 1, a liquid transport container 20 according to the present invention is loaded on a unicycle-type hand truck 10 with wheels 18 and legs 14 fixed to a frame 16, and is placed on a tray 11 shown by two-dot chain lines, or It is directly fixed to the frame 16 with suitable fixing means such as a fastening band, a hook, or a set screw without using a mounting plate.

However, it is not always necessary to use such fixing means, and the liquid transport container 20 is secured to the transport vehicle 10 by utilizing the weight of the contents and the frictional resistance or physical engagement between the bottom wall surface 26 and the frame 16. It can be stably mounted on top.

The liquid carrying container 20 has one top wall surface 22, one bottom wall surface 26. and a hexahedral hollow vessel body consisting of four side wall surfaces, which can be integrally molded by known blow molding of polyethylene resin or the like.

In addition, the liquid transport container 20 has a bottom wall surface 26 that slopes downward from the front toward the rear with the legs 14 of the transport vehicle 10 on the ground, forming a retainer 25 for the contents at the rear of the bottom wall surface 26. .

Since this liquid reservoir 25 is formed at the lowest position within the transport container 20, it is convenient for taking out the liquid without leaving it in the container.

The angle of inclination of the bottom wall surface 26 needs to be set so that the liquid remaining at the bottom of the transport container 20 can naturally flow down into the liquid reservoir 25 due to its own weight. If it is too large, the effect of reducing the weight of the contents by the front overhang portion 23 when the transport vehicle is running, which will be described later, will be impaired, so it is desirable to set the angle to 20 degrees or less from the front of the frame 16 toward the rear.

On the other hand, the front wall surface 24 of the liquid transport container 20 located above or in front of the fixed position of the wheels 18 is inclined downward from the front toward the rear at a larger angle of inclination than the bottom wall surface 26.

Due to the inclination of the front wall surface 24, the front projecting portion 2 of the liquid conveying container 20 is positioned above or in front of the fixed position of the wheel 18.
3 is formed, and the front projecting portion 23 functions as a means for increasing the liquid storage volume of the transport container 20, and when the bundle 12 is lifted upward and the legs 14 are released from the ground 30 in order to move the transport vehicle 10. act as an additional balancing weight above or in front of the fixed location of the wheels 18 to reduce the force required by the operator to lift the bundle 12.

Therefore, such a front projecting portion 23
When moving the bundle forward in the direction of arrow F, the bundle supporting force of the worker is reduced, creating load carrying conditions with less fatigue.

Further, at the rear of the upper wall surface 22 and above the liquid reservoir 25, there is provided an opening 28 with a cap for inlet/output of the liquid contained therein.

With the cap removed, the opening 28 may allow the contents to enter or exit the transport container 20 by using any liquid access means, such as an injection or suction hose, a dropper, or the like.

It is desirable that the opening 28 has a relatively large opening area to facilitate operation of the liquid inlet/outlet means.

In the present invention, the inclination angle of the front wall surface 24 is set so that the center of gravity of the container and its contents is adjusted as much as possible without impairing the operability of the transport vehicle 10 and increasing the capacity of the transport container 20. From this point of view, at least the bottom wall surface 2 is required to be located at the front.
It is necessary to slope downward with an angle of inclination greater than 6.

On the other hand, in a preferred embodiment of the present invention, the top wall surface 22 of the transport container 20 is designed to ensure maximum liquid storage volume without leaving any void space above the front wall surface 24 of the transport container 20 when the legs 14 are in contact with the ground. 14 is preferably substantially parallel to the ground 30 or slightly inclined upward from the front toward the rear, and by doing so, the balance weight effect of the front overhang portion 23 is also improved.

Further, an opening 21 with a cap for draining liquid can be provided above the front wall surface 24 if necessary.

This opening 21 is located at the front end 13 of the wheel 18 or frame 16.
bundle 1 of the transport vehicle 10 with the fulcrum relative to the ground 30
2 can be brought closer to the ground 30 by lifting it higher than when it is running, so the front wall surface 2 is inclined in the opposite direction to when the legs 14 touch the ground or when the transport vehicle 10 is running.
The remaining liquid in the container 20 can be collected in the vicinity of the opening 21 by using 4 as a liquid flowing down surface.

Therefore, when replacing the contents or cleaning the inside of the transport container, the remaining liquid can be easily and reliably drained by removing the liquid draining cap at this liquid draining position.

As is clear from the above description, the present invention provides a liquid reservoir at the rear of the liquid transport container, and a portion functioning as a means for increasing the liquid storage volume and a balance weight means at the front of the liquid transport container. It has excellent practical value as it improves safety when driving and operability when loading and unloading contents.
