Description

[Detailed description of the invention] This invention relates to a multi-headed spray pipe for spraying liquid such as agricultural chemicals.

Multi-head spray pipes, which have multiple spray heads attached to a single pipe, are used when spraying pesticides on many rows at once or when irrigating crops in large quantities.

However, since conventional pipe bodies were made of long metal pipes such as aluminum pipes, they were inconvenient to prepare for work and handle after work was completed.
Further, there were inconveniences such as the need for a long space for storage. Further, when attaching the spray tube to the metal pipe, it is necessary to attach the spray tube so as to accurately match the hole provided in the pipe, which has the disadvantage of poor assembly efficiency.

The object of this invention is to solve the above-mentioned drawbacks by providing a multi-head spray pipe in which a plurality of spray heads are attached to a flexible hose made of plastic or rubber.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

FIG. 1 shows a state in which the multi-head spray pipe 1 according to the present invention is attached to a support rod 2 and sprays from a large number of spray heads 3 at once in use for pesticide spraying work. As shown in FIG. 2, the multi-head spray pipe 1 has a hose 4 made of plastic or rubber.
and a spray head 3, which is attached to a support rod 2 by a clamping fitting 5 attached to a hose 4.

As shown in FIGS. 3 and 4, the main body of the spray head 3 consists of two halves 6 and 6' that sandwich the hose 4, and a cylindrical packing 8 having a cut-off part 7 is fitted on the inner periphery. , the hose 4 is pressed against the inner periphery of the packing 8 and is integrated with screws 9. A communication hole 10 is provided in the packing 8 and the divided body 6', and a threaded cylinder 11 is protruded around the communication hole 10. After the divided bodies 6, 6' are attached around the hose 4 as described above, a hole 12 is made in the hose 4 by inserting a punch such as an awl into the communication hole 10.

Also, a packing 13 is provided inside the threaded cylinder 11.
A nozzle 14 is inserted through the nozzle 14, and the nozzle 14 is fixed to the divided body 6' with a cap nut 15.

The above embodiment is suitable for the case where the hose 4 is made of a hard material, but the examples shown in the following FIGS. 5 to 7 are suitable for the case where the hose 4 is made of a soft material. The configuration is as follows.

The main body of the spray head 3 in this case also consists of divided bodies 6 and 6' connected by screws 9, and one divided body 6' has a communicating hole 10 and a threaded cylinder 11. Further, the mounting hole 16 for the hose 4 formed by each of the divided bodies 6, 6' is designed to clamp the hose 4 in a compressed state at both ends thereof, and to make the hose 4 watertight at the compressed and clamped portions.

Also, insert a drilling tool such as an awl into the hole 12 of the hose 4 through the communication hole 10 of the one divided body 6'.
Opening is the same as in the previous case.

Further, a spray nozzle 14 is attached to the threaded cylinder 11 via a packing 17.

Since the multi-headed spray pipe of this invention is constructed as described above, when the clamping tool 5 is removed from the support rod 2, the hose 4 is detached from the support rod 2, and due to the flexibility of the hose 4 itself, it can be freely moved. It can be rolled up or rolled up.

As described above, since this invention has a plurality of spray heads attached to a plastic or rubber hose, it can be folded up or rolled up into a smaller size when stored or transported. Therefore, it is much easier to handle than the conventional straight type.

In addition, the hole that connects the hose and the spray head can be opened by inserting a punch from the head side after the spray head is installed, so there is no need to be aware of whether it matches the hole when installing the head. do not have. Therefore, it is possible to assemble efficiently, and the position of the head and the hole of the hose can be precisely aligned.
