Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a backpack for suspending a bag or the like containing a spraying agent and holding it on the back when spraying agricultural chemicals.
[0002]
[Background Art and Problems to be Solved by the Invention]
As a spraying device used when spraying agricultural chemicals, fertilizers, etc. on agricultural land, it has been known that a thick cloth bag 2 with high strength is attached to a metal frame 1 as shown in FIG. Yes. A nozzle 4 is connected to an opening 3 provided at one end of the bag 2, and the user carries out a spraying operation while carrying the spraying device as shown in FIG. 2.
[0003]
However, in the spraying device of FIG. 1, it is necessary to transfer the spraying agent contained in the packaging bag at the time of purchase to the cloth bag 2 at the time of spraying, and it is necessary to wash the cloth bag 2 after spraying. It is troublesome. In order to solve such a problem, it is conceivable that the spraying agent sold in a bag is suspended and held as it is to spray the drug.
[0004]
An object of the present invention is to improve handling at the time of spraying work in a spraying device that suspends and holds such a spraying agent storage bag.
[0005]
[Means / Actions / Effects to Solve Problems]
The present invention has been made in order to effectively solve the above problems, and provides a backpack for spraying having the following characteristics.
[0006]
The spraying backpack of the present invention is used to suspend and hold a packaging body (packaging bag, packaging box, etc.) containing a spraying agent and carry it by carrying it. The spraying backpack of the present invention is characterized in that it includes a “holding ring that engages with a spraying port of a suspended packaging body and keeps the packaging body stable”.
[0007]
In the backpack of the present invention having the above configuration, since the holding ring fixes the spraying opening of the package, the suspended package is stably held on the back side and does not flutter. Therefore, it is possible to perform the spraying work comfortably.
[0008]
In the spraying backpack of the present invention, "the holding guide mechanism that engages with the spraying nozzle extending from the spraying port of the suspended package and guides the nozzle from the back side to the front side of the user" May be provided. Thereby, there exists a merit that a nozzle is stabilized at the time of spraying work.
[0009]
The spreading backpack of the present invention preferably has a skeleton made of a frame material. Thereby, weight reduction of a backpack can be achieved. Moreover, it is preferable to provide a U-shaped foldable leg part rotatably connected to the frame material. The folding leg is connected to the frame material by a strap, and the folding device has a self-supporting function by maintaining the folding leg and the frame material at a certain relative angle by the strap. It becomes.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 3 is a perspective view showing a backpack 10 according to an embodiment of the present invention.
[0011]
Frame made of frame The backpack 10 has a frame made of a metal frame. That is, two vertical frames 12 and 13 extending in the vertical direction are connected at the upper end by a horizontal frame 11 extending in the horizontal direction. The frames 11, 12, and 13 are a single piece in the illustrated example. Two vertical frames 12 and 13 extending in parallel with each other are connected and fixed by three horizontal frames 20, 30 and 40. These horizontal frames are entirely or partially covered with elastic members 21a, 21b, 31, 41a, 41b that function as cushions.
[0012]
The backpack 10 includes two shoulder belts 18 schematically illustrated by broken lines. Each belt 18 is fixed so as to connect the horizontal frames 20 and 40, and the user can carry the backpack 10 on the back by using this belt. In the illustrated example, the backpack has a metal frame skeleton, so it is relatively lightweight and convenient to carry on the back.
[0013]
Folding leg part The backpack 10 includes a folding leg part 50 that is rotatably connected to the vertical frames 12 and 13. The foldable leg portion 50 is formed of a U-shaped frame material as a whole, and includes parallel frames 52 and 53 that extend in parallel to each other, and a bottom frame 51 that connects the parallel frames. Parallel frames 52 and 53 are rotatably connected to the vertical frames 12 and 13, respectively. The bottom frame 51 is a portion that actually contacts the ground.
[0014]
The bottom frame 51 is connected to the horizontal frame 40 by a strap 55. The strap 55 limits the maximum angle of the foldable leg 50 with respect to the backpack 10. That is, the folding leg portion 50 is prohibited from expanding at a larger angle than the state shown in FIGS. In the state shown in FIGS. 3 and 5, the backpack 10 can stand on its own, which is convenient when taking a break in the middle of the spraying operation. On the other hand, the foldable leg 50 is pivotally connected to the backpack 10, so that the entire foldable leg 50 can be folded by folding the foldable leg 50 during storage. Since it is plate-shaped, a large space is not required as a storage place.
[0015]
Suspension mechanism A hook mounting plate 15 is fixed along the horizontal frame 11, and hooks 16a and 16b are provided on both sides thereof. A packaging bag 100 as shown in FIG. 4 is suspended and held on the hook portion. The packaging bag 100 is sold in a state in which a spraying agent is accommodated, and includes a hooking hole 101 at the upper left and right positions. As shown in FIG. 5, the user can perform the spraying work by hanging the purchased spraying agent together with the bag on the hooks 16a and 16b.
[0016]
Resin ring ( holding ring )
In the space between the horizontal frames 20 and 30, the cloth material 25 is wound and fixed around the vertical frames 12 and 13 (see FIG. 3). A strap 26 is sewn at the center of the cloth material 25, and this strap 26 holds a resin ring 27. As indicated by arrows in FIG. 5, the resin ring 27 engages with the spout 102 of the packaging bag 100 in a suspended state, and keeps the suspended state of the packaging bag 100 stable. Thereby, since the packaging bag 100 is stably held even during the spraying operation, the spraying operation can be performed comfortably. A cloth knob 28 is sewn on the resin ring 27. While picking the knob 28, the user can engage the resin ring 27 with the spray port 102 relatively easily.
[0017]
Spray nozzle guide mechanism In an actual spraying operation, the spray nozzle 110 is connected to the spray port 102 of the packaging bag as shown in FIG. The spray nozzle 110 is fixed by screw engagement with a screw portion (not shown) that appears after the cap 102a is removed from the spray port 102. The spray nozzle 110 is supported by a guide mechanism 60 provided in a lower portion of the vertical frame 12. The guide mechanism 60 engages with a spraying nozzle 110 extending from the spraying port 102, guides the nozzle from the back side to the front side of the user, and improves the workability of drug spraying.
[0018]
FIG. 7 is a partially enlarged view for explaining the guide mechanism 60 in detail. The guide mechanism 60 includes a plate-like main body 61 and a holding plate 65 that actually engages the nozzle 110. The plate-like main body 61 is connected to the periphery of the vertical frame 12 so as to be wound with a relatively large gap, and thus can freely rotate around the vertical axis. A pin member 12a is erected in the vicinity of the lower end of the vertical frame 12, and the plate-like main body 61 is held so as to rest on the pin member 12a.
[0019]
The holding plate 65 is made of an elastic plate having a substantially C-shaped cross section and engages around the nozzle 110 (see FIG. 6). The holding plate 65 is connected to the surface of the plate-like main body 61 using two bolt members 62a and 62b. A long hole 61a is formed in the plate-shaped main body 61, and one bolt member 62b is passed through the long hole 61a. Accordingly, the holding plate 65 can be rotated along the surface of the plate-like main body 61 around the bolt member 62a. Therefore, the angle of the nozzle 110 guided from the user's back side to the front side can be appropriately adjusted.
[0020]
In the embodiment illustrated and described above, the bag containing the spray agent is hung on the backpack 10, but it is not necessary that the bag is hung on the backpack 10, but a box or the like. May be.
