Description

[Detailed Description of the Invention] [Industrial field of application] This invention is an agricultural equipment that can be mounted on a carrier such as an automobile or a power carrier for farming and spray the stored liquid fertilizer or other liquid directly onto a field or the like. It is related to the tank for use.

[Prior Art] A tank made of a vinyl chloride resin, polyethylene, or an individual resin material such as FRP (fiber reinforced plastic) is lightweight and tough, so for example, this tank is used as a carrier for automobiles, agricultural power carriers, etc. After the liquid fertilizer is stored in the tank and the liquid fertilizer is stored in the tank, it is widely practiced to drive the automobile or the like to the field to spray the liquid fertilizer in the tank.

Such agricultural tanks generally have an inlet for liquid fertilizer, etc. at the top, and a drainage port is formed at the bottom of the tank body, such as at or near the bottom, and a valve made of metal or synthetic resin is provided at this drainage port. While being attached, a spray nozzle or the like is connected to this valve, and by appropriately opening and closing the valve, liquid fertilizer or the like is directly discharged or sprayed from the nozzle.

[Problems to be solved by the invention] In such a conventional agricultural tank, the liquid is controlled by opening and closing the valve, but since the valve is made of metal or synthetic resin as described above, it has a relatively heavy weight. Therefore, reinforcement of the mounting part is required.

In addition, when it is used by being mounted on a carrier such as an automobile or a power carrier for agricultural use, during operation, the valve portion is liable to be damaged by another object, causing troubles such as liquid fertilizer flowing out.

Furthermore, when the liquid fertilizer is in the form of mud containing solid matter such as lower fertilizer, not only is the part of this case often blocked by solid matter for smooth spraying, but also the valve is blocked by solid matter. In addition, there are frequent operational problems such as being unable to use the valve unless the valve is disassembled to remove this solid material, and if the valve to be installed in the tank is made of metal, installation becomes extremely troublesome. In addition, there was an economical disadvantage such as increased costs.

In view of such a current situation, the present invention intends to provide an agricultural tank that can easily and easily adjust and stop the flow rate associated with the discharge of liquid in the tank, and that is easy to handle. is there.

[Means for Solving the Problems]

In order to achieve the above object, the agricultural tank of the present invention has a drain port formed in a lower portion of a tank main body for storing liquid such as liquid fertilizer and a twist for discharging the liquid in the tank main body. And a non-conformable discharge pipe, a flow control pipe having flexibility with respect to twisting and bending that is twisted by the rotating operation of the discharge pipe to control the flow rate is interposed.
Further, the discharge pipe is configured such that the tip end thereof is detachably attached to a locking portion provided in the tank body.

In the present invention, the flow control pipe includes a drain port formed in a lower portion of a tank body that stores liquid such as liquid fertilizer, and a drain pipe that is not adaptable to twisting for draining the liquid in the tank body. It is provided between and.

This flow rate control pipe is made of a soft hose that can easily adapt to twisting and narrow the inner diameter of the pipe, and can easily follow bending as well. A hose having a waterproof coating formed on a soft pipe made of a synthetic resin such as vinyl chloride resin, polyethylene, polypropylene, or a synthetic rubber, or a cloth pipe such as a hose for fire fighting is used.

Also, although there is no special limitation on the length of the flow control pipe,
If it is too short, the adaptability to twisting and bending will be poor,
If it is too long, it will take time to operate and it will be difficult to reliably control the flow rate, so the most suitable length (length excluding the fitting margin with the drainage port and the discharge pipe) is in the range of 200 to 500 mm. Is preferred.

On the other hand, the discharge pipe for discharging the liquid in the tank main body is made of a vinyl chloride resin, polyethylene, polypropylene or the like and is made of a hard tubular body that is not adaptable to twisting. Each of the tubes is made of a material that is not attacked by the liquid contained in the tank body.

[Action]

The agricultural tank of this invention is twisted by a rotating operation of the drain pipe between the drain port at the bottom of the tank body and the drain pipe for draining the liquid in the tank body to control the flow rate. Since the flow rate control pipe having flexibility with respect to bending is interposed, the flow rate control pipe is twisted following the rotation of the discharge pipe which is not flexible with respect to twisting.

Therefore, the flow rate of the liquid sent from the tank body to the discharge pipe can be adjusted by adjusting the degree of the twist, and the liquid discharge can be completely stopped by making the turning amount extremely deep. It is possible.
