Description

[Detailed Description of the Invention] This invention relates to a spray tube support device for a backpack-type power sprayer.

This type of power sprayer consists of a machine body that integrates a chemical solution tank, a pressurizing pump, and a prime mover, a rubber hose for pressure-feeding the chemical solution from the machine body, and a spray pipe at the end of the rubber hose. It has a handle at the base and a spray head at the tip.

Conventionally, with this type of power sprayer, you leave the spray tube on the ground, etc., carry the machine on your back with both hands, then pull the spray tube to your hand with a rubber hose, hold it in your hand, and work on it. I left it on the ground and used both hands to lower the aircraft from my body, but during the attachment and detachment of the aircraft from my body,
The spray pipe has the drawback that it is easily damaged by rolling on the ground, and in particular, the nozzle at the tip is easily clogged with mud.

This invention aims to eliminate the above-mentioned drawbacks, and provides a spray pipe support device for a backpack-type power sprayer that allows the spray pipe and the machine body to be attached and detached from the body without leaving the spray pipe on the ground. be.

Another object of this invention is to provide a spray tube support device for a backpack-type power sprayer that allows the spray tube to be attached to and removed from the body of the machine extremely easily while carrying the machine on one's back. .

Furthermore, another purpose of this invention is that when the hanging tool is not needed for spraying work, the rod can be rotated so as not to interfere with the work, and the hanging tool can be stored at the rear on one side of the machine. To provide a spray tube support device for a backpack-type power sprayer that can be supported.

That is, this invention provides a spray machine equipped with a spray pipe, in which a rod is provided with a hanger at the tip of the spray pipe so that the hanger can freely protrude toward the front of the machine. The gist of the present invention is the structure of a spray pipe support device in a backpack-type power sprayer, which is provided on one side of the machine body so as to be rotatable back and forth.

This invention will be explained with reference to the illustrated embodiment. Reference numeral 1 denotes a machine body, and a frame 2 integrally supports a chemical solution tank, a pressurizing pump, a prime mover, and the like.

Reference numeral 3 is a supporting metal fitting fixed to the side of the frame 2, and a rod 4 is supported so as to be rotatable back and forth.

The support fitting 3 is configured so that the rod 4 can be rotated forward to support the tip of the rod 4 so as to protrude to the front of the fuselage 1, and can also be used as a case for storing the rod 4 by rotating it backward.

A latching tool 5 is provided at the top of the tip of the rod 4, and the latching tool 5 can freely protrude toward the front of the body 1 as the rod 4 rotates back and forth.

6 is a rubber hose for pumping the chemical solution, and 7 is a spray pipe.

The above-mentioned hook 5 supports the spray tube 7 in a detachable manner, and is preferably formed of a highly elastic plate spring or the like as in the illustrated embodiment.

8 is a handle of the spray tube 7, and 9 is its spray head.

Since this invention is constructed as described above, first, the rod 4 is rotated to project and support the hook 5 at the front of one side of the body 1.

Next, when the spray pipe 7 is hooked to this hook 5, the handle 8 will protrude forward of the machine body 1, the middle part will be supported by the support metal fitting 3, and the spray head 9 will protrude to the rear and be stably supported. Become.

The spray pipe 7 supported by the fuselage 1 in this way can be attached to and removed from the body together with the fuselage 1 without leaving it on the ground, etc., so damage to the spray pipe 7, especially clogging of the nozzle of the spray head 9 due to mud, is avoided. This can be prevented.

Furthermore, when this power sprayer is carried on the back, the handle 8 of the spray tube 7 can be projected and supported at a position where the worker can see it directly, so the worker can freely handle it.

Further, during the work, it is convenient to rotate the rod 4 rearward and fold it into the support fitting 3 so that it does not interfere with the work.

When the work is finished, the operator rotates the rod 4 again while carrying the machine 1 on his back, so that the latching tool 5 protrudes and supports the front of the machine 1, so that the worker can hold the latching tool 5 at the tip of the rod 4 with his fingertips or This can be confirmed by direct viewing, and the spray pipe 7 can be easily hooked onto this.

As described above, according to the present invention, since the aircraft can be handled without leaving the spray pipes on the ground, it has the practical benefit of preventing damage to the spray pipes, especially clogging of the nozzle with mud. be.

In addition, with this invention, the rod tip protrudes and is supported at the front of the machine, so its position can be easily confirmed, and the spray tube can be easily attached to and removed from the machine while the machine is still attached to the body. It has practical benefits that can be achieved.

In addition, with this invention, when the hanging tool is not needed for spraying work, the rod can be rotated backward and the hanging tool can be stored and supported at the rear on one side of the machine, allowing efficient spraying work. It also has practical benefits that can be achieved.
