DETAILED DESCRIPTION OF THE INVENTION An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a chemical solution processor for grapes and the like (hereinafter referred to as a gibberellin processor) according to the present invention. The gibberellin processing device 1 includes a drug solution feeder 4 including a tank part 2 for containing a drug solution obtained by diluting gibberellin with water, and a supply part 3 for pressure-feeding the contained drug solution. Further, the processing section 7 is provided with a cup section 5 for accommodating a bunch of grapes (fruit cluster) and a nozzle section 6 for ejecting a chemical solution to the accommodated bunch. Further, a grip portion 11 including a socket portion 8 that detachably attaches and supports the cup portion 5 so as to connect the both, and a handle 9 that is extended at a lower portion of the socket portion 8 and can be gripped. I am prepared. A supply pipe 12 that connects the chemical liquid feeder 4 and the processing unit 7 with flexibility,
The return pipe 19 and the harnesses 14 form a connecting portion 16.

The detailed configuration of each unit will be described below.
First, as shown in FIGS. 1 and 2, the chemical liquid feeder 4 has an integral structure that enables the liquid supply and maintenance work by detachably joining the supply part 3 to the upper opening of the tank part 2. It is configured. The tank portion 2 is installed with the liquid absorption pipe 21 having a wire mesh filter 20 at the bottom of the tank chamber and the end of a return pipe 19 provided with a dense filter 18 described below.

The supply unit 3 sucks the chemical liquid from the liquid suction pipe 21 and sends it to the processing unit 7 through the supply pipe 12 to supply the liquid to the treatment unit 7.
A rechargeable or dry battery type battery 24 that drives the liquid supply pump 23 is removably housed.
An operation switch 26, which is installed on the grip portion 11 side via the harness 14 so as to be operable at hand, and a control unit 27 which is connected to the battery 24 and the liquid supply pump 23 to control the switch.

The operation switch 26 is an ON / OFF switching holding type switch, and its characteristics and the control unit 27 push the finger gripping the gripping unit 11 to move it O.
When N operation is performed, the liquid supply pump 23 is driven and the chemical liquid in the tank portion 2 is pressure-fed to the nozzle portion 6 of the processing portion 7 via the supply pipe 12, and the plurality of nozzle holes 28 included in the nozzle portion 6 to the cup portion 5. The drug solution is supplied to the contained fruit cluster. When the operation switch 26 is pushed again, the OFF operation is held and the liquid supply pump 23 is stopped. The operation switch 26
If the finger continues to be pushed, the pressure-feeding supply amount of the liquid supply pump 23 can be made variable so as to increase the supply amount of the chemical liquid, for example. Further, the chemical liquid feeder 4 is provided with a handle portion 29, a shoulder strap 31 and the like on the upper portion of the main body of the supply portion 3.

Explaining the filter 18,
In the filter 18 shown in this embodiment, a dense and flexible film-like member capable of blocking the passage of pollen is formed in a bag shape, and its opening is attached to a middle portion of the return pipe 19. By fixing, the filter 18 is installed in the vertical direction of the tank chamber, and the filter 18 is maintained in an expanded state in the chemical liquid to improve the filtering performance.

Further, the filter 18 in the illustrated example has a double structure. In this example, the bag-shaped outer filter 17 is made of nylon stocking cloth, and the inner filter 32 is made of coffee filter paper. By doing so, the double membrane filter can be easily manufactured with an inexpensive member that is easily available. Further, the double-structure filter 18 can maintain the shape and improve the durability in the chemical solution.

Then, the chemical liquid containing pollen and returned via the return pipe 19 is first filtered by the inner filter 32,
Small particles such as pollen attached to the filter 32 of the filter paper easily fall down due to vibrations etc. and have a large capacity, so that it can be used for a long period of time and easily replaced when clogging occurs. And it can be performed at low cost. The outer filter 17 further filters the chemical solution and protects the inner filter 32.

Therefore, unlike the conventional one, the filter 18 is not provided in the cup portion 5 so that the clogging of pollens does not hinder the return of the chemical liquid, so that the filter 18 is made tight and the filtering performance is improved. While feeding pump 2
The filter 20 on the 3 side can be slightly roughened.
Further, since the load due to the excessive negative pressure is not applied to the liquid supply pump 23, smooth operation can be performed while saving energy. The filter 18 has a mounting piece 33 having an opening formed in the middle of the return pipe 19 and a mounting tool 34 such as a band.
It is advisable to use a removable structure.

Next, the processing section 7 will be described with reference to FIG. The cup portion 5 of the processing unit 7 has a tubular portion into which a fruit cluster can be inserted and accommodated from below, and a tubular screw portion 36a formed at an end portion where the lower portion of the tubular portion is converged into a funnel shape. The screw portion 36a constitutes a joint portion which is detachably screwed to a screw portion 36b of the gripping portion 11 described later. Further, the cup portion 5 has an edge guide 37 formed by means such as inserting an edge rubber member into the upper peripheral end of the tubular portion, and the edge guide 3 is formed.
By arranging the nozzle portion 6 below 7 it is possible to facilitate storage without damaging the fruit cluster during storage, and the height of the edge guide 37 prevents the chemical liquid from splashing outside during ejection. I am trying.

Further, the nozzle portion 6 is formed by forming a flexible pipe into a ring shape, and a plurality of nozzle holes 28 are provided at the inner peripheral side thereof at substantially equal intervals, and the supply pipe 12 is provided on one side of the outer peripheral side. The liquid medicine that is connected and delivered from the liquid supply pump 23 is supplied to each nozzle hole 2
By jetting from 8 toward the center of the cup portion 5 in a substantially horizontal or downward direction, uneven supply to the entire fruit cluster is prevented. At this time, it is desirable that the ring-shaped nozzle portion 6 fits and supports a part of the outer circumference of the tube into a concave groove formed at a predetermined height position of the cup portion 5, and in this case, the fruit cluster Since the insertion diameter of the nozzle can be increased and the positioning and support can be stably performed in the concave groove, the displacement of the nozzle portion 6 due to the contact with the fruit cluster can be prevented.

Further, as shown in FIG. 4 to FIG.
When a dish-shaped nozzle hole (shown by a dotted line in FIG. 5) is formed on the surface of a flexible tube, when the tube is bent into a ring shape, a vertical closed nozzle hole 28 is formed. Since the medicinal solution is ejected in a streak shape by being guided by the wall thickness of the pipe at the time of ejection, even if the number of the nozzle holes 28 is reduced, the medicinal solution will be ejected while being diffused in a mist state, which causes unevenness of the medicinal solution to the entire fruit cluster. Efficiently supply no jet. Further, when the operation of the liquid supply pump 23 is stopped by the OFF operation of the operation switch 26, the nozzle hole 28 having the above-described configuration is changed from the dotted line state expanded by hydraulic pressure at the time of jetting shown in FIG. 6 to the original closed state of the solid line. Since it is possible to return quickly, it is possible to easily prevent liquid dripping due to residual pressure or the like.

Further, the cup portion 5 in the illustrated example shows an embodiment suitable for reusing a used general-purpose transparent PET bottle that has been used. That is, in this case, a PET bottle having a diameter suitable for accommodating and processing a bunch of different sizes is selected in two stages of the primary gibberellin treatment and the secondary gibberellin treatment performed together with the growth of the bunch, and By cutting an appropriate place in the middle of the cylinder of the bottle, it is possible to easily and inexpensively obtain a container having a screw portion 36a in the funnel portion and having a predetermined length and capacity, and to utilize the resources of the used PET bottle. There are advantages. According to this, one grip 1
Since the cup portion 5 made of several kinds of PET bottles can be attached to and detached from the single socket portion 8 via the screw portion (attachment portion) 36a having a common shape, the cup portion 5 can be easily switched and used with an inexpensive structure. Further, since the funnel-shaped portion of the cup portion 5 is close to the entire circumference of the lower part of the fruit cluster, the nozzle hole 2 is formed on the inner surface thereof.
It is possible to prevent the unevenness of processing by ejecting the chemical solution from 8.

The supply pipe 12 includes a nozzle portion 6 and a grip portion 11.
In the middle of, the connection is made with a plug-in type connection tube 38 capable of one-touch contact / separation, and the edge guide 37 and the nozzle portion 6 can be pulled out upward if necessary. As a result, by removing the edge guide 37 and the nozzle portion 6 with the cup portion 5 removed from the socket portion 8, the cup portion 5 formed of another PET bottle is formed.
Since it can be reassembled, the waste of replacing the edge guide 37 and the nozzle portion 6 when the cup portion 5 is soiled or damaged can be eliminated, and a new cup portion 5 can be mounted at a low cost. In this case, if the edge guide 37 and the nozzle portion 6 are bonded or integrally formed, it is possible to more easily attach and detach the cup portion 5. 39 is the cup portion 5
It is a hook-shaped hanging member projecting laterally, and the hanging unit 39 can be hooked on a grape shelf or a branch during the gibberellin processing work to support the processing unit 7.

Next, the grip 11 will be described. As shown in FIG. 3, the socket portion 8 of the grip portion 11 has a threaded portion (joint portion) 36b into which the threaded portion 36a of the cup portion 5 is screwed and is formed in the upper portion of the tubular member, and the cup portion is formed in the screw bottom. 5 is provided with a contact plug 42 having a through-hole 41 communicating with the inside of the return pipe 1, and the return pipe 1 is inserted into the contact plug 42, the handle 9 and the socket portion 8.
9 is connected.

Further, in the lower portion of the socket portion 8, a screw portion 43 for connecting the upper portion of the handle 9 by screwing is formed, and by connecting the both, a long grip portion 11 is formed in series, and the handle 9 is formed. The structure is such that the gibberellin processing work performed by gripping can be easily performed in a comfortable position without raising the hand. Further, the gripping portion 11 of the illustrated example has a through hole 44 formed in the middle of the socket portion 8 and draws the handle 9 and the supply pipe 12 passing through the inside of the socket portion 8 from the through hole 44 to form a gap between the grip portion 11 and the nozzle portion 6. By providing the joint pipe 38, the supply pipe 12 is prevented from being exposed as much as possible, the handle 9 is easily gripped at the time of working, and the supply pipe 12 and the branches and leaves are prevented from contacting each other, so that the processing section 7 is placed in a proper posture. It is possible to facilitate the gibberellin treatment work while supporting it.

The gibberellin processing device 1 configured as described above
Holds the handle 9 with one hand while holding the drug delivery device 4 and holds the handle 9 in the cup 5 while lifting the handle 9, and then turns on the operation switch 26 to turn on the feed pump 23. Is driven to deliver the liquid medicine in the tank portion 2 to the nozzle portion 6 through the supply pipe 12 and jet it out simultaneously from the plurality of nozzle holes 28, so that the liquid medicine can be appropriately supplied to the contained fruit cluster. . Further, when the operation switch 26 is pushed again to be turned off, the liquid supply pump 23 is stopped and the ejection of the chemical liquid from the nozzle portion 6 is also stopped, so that the gibberellin treatment work of this fruit cluster is promptly completed and the next fruit cluster is processed. Shift to work.

At this time, the nozzle portion 6 formed in a ring shape
Is a plurality of nozzle holes 28 provided on the inner peripheral side thereof at substantially equal intervals.
Since the drug solution is jetted substantially horizontally or downward toward the central portion of the cup portion 5, the gibberellin treatment can be efficiently performed without causing unevenness of supply to the entire fruit cluster. The treated chemical liquid is promptly collected in the central portion of the cup portion 5 having a funnel-shaped bottom, and the tank portion 2 is returned through the return pipe 19 and the filter 18 without applying a large negative pressure resistance to the liquid supply pump 23. Circulate back to. The filter 18 which is made tight so as not to hinder the return of the chemical liquid can perform smooth operation while suppressing the consumption of the power source without increasing the filtration performance and placing a heavy burden on the liquid supply pump 23. .

In such a work, the gibberellin processor 1 forms a cylindrical screw portion 36a in the lower portion of the cup portion 5 and in the upper portion of the grip portion 11 into which the return pipe 19 is inserted.
A screw portion 36b that communicates with the return pipe 19 and into which the screw portion 36a of the cup portion 5 is screwed is formed.
Since it is configured to be attachable to and detachable from the grip portion 11 via 6a,
For example, when performing the primary gibberellin treatment and the secondary gibberellin treatment of the fruit cluster using the cup portions 5 having different sizes, one gripping portion 11 and the drug solution feeder 4 are used, and several types are used for the socket portion 8. By attaching / detaching the cup portion 5 of the first embodiment through the screw portion (joint portion) 36a having a common shape, the work associated with the primary gibberellin treatment and the secondary gibberellin treatment can be easily switched by a low-cost configuration and efficiently performed. .

The attaching / detaching means for the grip portion 11 of the cup portion 5 has a structure in which the screw portion 36a formed on the cylindrical portion of the cup portion 5 and the screw portion 36b of the grip portion 11 are screwed, but it has another constitution. A one-touch detachable structure may be used. Further, in this embodiment, the gibberellin processing device 1 that processes gibberellin on the fruit clusters of grapes using gibberellin as a liquid medicine has been described, but according to the configuration of this embodiment, a chemical liquid such as a disinfectant is stored in the tank portion 2 and the cup portion It can also be used as a disinfecting treatment device for disinfecting fruits and the like within 5.

[0027]
