Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure accumulating spraying device used for watering garden trees, spraying chemicals and the like.

[0002]

2. Description of the Related Art A conventional pressure-accumulation type spraying device is a hand-held pumping device having a vertically-moving handle, such as a bicycle inflator, for a vertically long hollow cylindrical tank for containing water and the like. And a handheld injector via a flexible hose.

In this spraying device, air is pressurized and filled from the pump device into the tank by moving the handle up and down in advance, and the injector is operated as necessary to spray the air by using air pressure. It was something to stop the water.

[0004]

In order to move the handle up and down, it is necessary to bend and extend the arm or waist many times while keeping the prone posture. Therefore, it is difficult for the elderly and children to handle. In addition, since the handle has a structure protruding above the tank, the overall height is large, which is unstable, which also makes the handle inconvenient. It should be noted that such a large overall height is a structure necessary for operating the steering wheel, and in reality there is no improvement measure.

The present invention has been made in view of the above circumstances, and provides a pressure accumulating spraying device capable of performing pressure filling of air easily and lightly by anyone and stably performing this work. The purpose is to provide.

[0006]

In order to achieve the above object, the present invention takes the following technical means. That is, the present invention comprises a base body, a tank supported on the base body, and a pedal movably held at the front portion of the tank. The pedal is provided at the front portion of the base body. Is characterized in that a notch is formed by opening a region directly below the front and in the vertical direction, and grounding portions are provided on the lower surfaces of both left and right sides of the notch.

Further, according to the present invention, the base body, the pedal which is vertically swingably held above the front side of the base body around the fulcrum provided near the rear portion of the base body, and the vertical direction of the pedal. It is characterized in that it comprises a tank supported on the base body in a state of filling the space between the movement locus and the fulcrum arrangement portion. A cover body for covering the tank is provided on the base body, and a recess opened forwardly and vertically is formed in the cover body in correspondence with the vertical movement locus of the pedal. It is also possible to

An injection port portion having an external thread on the outer peripheral surface and projecting upward is provided on the upper part of the tank, and a top hole matching the injection port part of the tank is provided on the upper part of the base body. A cover body having a cover is provided so as to cover the tank, and a nut member is screwed into an inlet port of the tank projecting from the top hole of the cover body to engage and hold the cover body with respect to the base body. It is also possible to do so.

[0009]

According to the present invention, since the pressure in the tank can be filled with air by stepping on the pedal held in the front portion of the tank, the operator remains upright (depressing and leaning). You can do that without any effort. Since the base body supporting the tank has a notch corresponding to the area directly below the pedal, mud and water droplets adhering to the feet do not enter the base body. Further, since the ground contact portions are provided on both left and right sides of the cutout portion, the pedaling force on the pedal can be firmly supported.

By forming the tank by maximizing the space on the base body so as to fill the space between the vertical movement locus of the pedal and the fulcrum near the rear, the tank is not made tall. A predetermined capacity can be secured. By providing the base body with the cover body having the foot insertion guide portions that sandwich the vertical movement locus of the pedal from both sides, it is possible to make the operating position of the pedaling force on the pedal constant.

In the case of providing the cover body covering the tank on the upper portion of the base body, the following is made in order to simplify the coupling structure of the base body and the cover body and to perform the coupling easily. That is, in the upper part of the tank, an outer peripheral surface is provided with an injection port part having a male screw part and protruding upward, and the cover body is provided with a top hole that matches the injection port part of this tank. Then, after the cover body is placed on the base body, the nut member is screwed into the inlet port of the tank protruding from the top hole of the cover body. As a result, the cover body is pushed down with respect to the base body, and the both are engaged and held.

If this structure is adopted, the base body and the cover body can be connected very easily, reliably and quickly.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 6 show a first embodiment of a pressure-accumulation spraying device 1 according to the present invention, in which 2 is a tank for storing water or chemicals and 3 is a flexible hose 4 in this tank 2. It is a handheld injector connected via. Reference numeral 6 is a pump device for pressurizing and filling the tank 2 with air.

In the spraying device 1, the pedal operating portion 8 is constructed so that the pedal 7 is projected to one side of the tank 2.
The pump device 6 can be operated by the foot operation part 8. In the following description, the side from which the pedal 7 protrudes (the right side in FIGS. 1 and 2) is referred to as “front”, the opposite side is referred to as “rear”, and the left and right sides (refer to FIG. Lower side) and "right" (upper side in FIG. 1).

The tank 2 and the pump device 6 are the casing 1
It is stored in 0. The casing 10 has a structure that can be divided into a base body 11 that supports the tank 2 and a cover body 12 that covers the upper side and has a substantially semicircular side surface. As shown in FIG. 4, a notch 13 is formed in the front part of the base body 11 by opening a region directly below the pedal 7 forward and downward, and a lower surface of a part left on both left and right sides of the notch 13 Is the grounding portion 14. Further, a recess 15 is formed at the front part of the cover body 12 so as to coincide with the notch 13 and is pulled out upward, and portions left on both the left and right sides of the recess 15 serve as foot insertion guides 16.

The internal space formed by the grounding portion 14 and the foot-placement guide portion 16 is necessary for accommodating a part of the stepping operation portion 8 (see FIGS. 1 and 2) which will be described later. There is. The foot insertion guide portion 16 as described above makes it possible to make the operating position of the pedaling force on the pedal 7 constant, prevent the foot from slipping off, and firmly support the pedaling force applied to the pedal 7 by the grounding portion 14. be able to. All of these are useful for improving the stability of the spray device 1. The recess 15 and the notch 13 also have an effect of preventing mud, water droplets, and the like attached to the foot from entering the casing 10.

In the base body 11, the ground portion 14
Has a sled shape extending to the rear end as it is, so that it can be easily slid on a lawn, for example. As shown in FIG. 2, the tank 2 is formed to have a relatively short height in order to increase stability, and a fulcrum (see a pivot 19 described later) on which the pedal 7 moves up and down, and a vertical movement locus of the pedal 7. So that the space between the base body 1
It is formed by maximizing the space above 1. The side shape of the tank 2 is an oval shape that is obtained by removing the formation of the recess 15 from the side shape (semicircular shape) of the cover body 12. Needless to say, this tank 2 has not only a watertight structure, but also a structure having pressure resistance to withstand the filling of pressurized air.

In the first embodiment, the tank 2 is made of metal, has a capacity of 2 to 3 liters, and has a capacity of 3 kgf / c.
It should be able to withstand an internal pressure of about m ² . 17 is tank 2
Inlet part 2a provided in a state of protruding upward in the upper part of the
And a safety valve 18 is provided. Two sets of pump devices 6 are provided so as to sandwich the left and right sides of the tank 2 and form a pair (see FIG. 1). Each of the pump devices 6 has a horizontal pivot 19 provided near the rear end of the side of the tank 2 as a fulcrum, and a cylinder 20 that is vertically swingably held with a rod end 20a facing forward.
A link 21 connected to the rod end 20a of the cylinder 20 and a spring 22 for pulling and urging the cylinder 20 upward.

A feed hose 23 is connected to the rear end of the cylinder 20 as shown in FIG. 1, and the other end of the feed hose 23 is connected to the rear surface of the tank 2. Between the connection between the cylinder 20 and the feed hose 23, or between the connection between the feed hose 23 and the tank 2, an air flow from the cylinder 20 to the tank 2 is allowed, but a check valve (shown in the figure) for preventing the back flow is shown. Is omitted).

In the first embodiment, in order to prevent an unreasonable force from acting on the cylinder 20, the cylinder 2 is inserted into the cylinder holding rod 25 having a groove-shaped cross section as shown in FIG.
0 was stored and fixed. The pivot 19, the spring 22, and the link 21 are indirectly connected to the cylinder holding rod 25. That is, the pivot shaft 19 is held by the hinge portion 26 provided on the base body 11 in a state of penetrating the rear end portion of the cylinder holding rod 25.

Further, the spring 22 is stretched around a proper position of the upper side of the cylinder holding rod 25 and a holding pin 27 projecting near the upper side surface of the tank 2. Further, the link 21 is swingably held by a pivot 29, which is provided so as to project near the upper part of the center of the side surface of the tank 2, as a fulcrum, and at its free end, as shown in FIG.
Is formed in a bifurcated shape so as to sandwich the rod end portion 20a from both left and right sides. And these are connected by the stop shaft 30 in a skewered shape.

On the other hand, on the front side of the cylinder holding rod 25, a long guide slot 31 (see FIG. 2) is formed so as to extend along the direction in which the rod end 20a of the cylinder 20 expands and contracts. Sliding pieces 32 provided at both ends of the stop shaft 30 are movably fitted to the stopper shaft 31. As shown in FIGS. 1 and 6, the left and right pump devices 6 are configured so that the front ends of the cylinder holding rods 25 are connected to each other by a crossover shaft 33 so that the cylinders 20 oscillate synchronously. ing. And this crossover shaft 3
Pedal 7 is attached to 3. The pedal 7, the transition shaft 33, and the cylinder holding rod 25 (at least the portion connecting the transition shaft 33 and the cylinder 20)
The foot operation section 8 is configured by.

Since two sets of the pump devices 6 are provided as described above, when the pedal 7 is stepped on, the pedaling force acts on both pump devices 6 evenly to reduce the loss.
The advantage is that structural rigidity is obtained and failure is less likely to occur. Further, since each cylinder 20 can have a relatively small diameter and stroke, it is possible to allow the tank 2 to have a large capacity without increasing the size of the spraying device 1. You can

In the spraying device 1 thus constructed, in a normal state, the spring 22 pulls the cylinder holding rod 25 upward to urge the cylinder 20 (pedal 7) to stop at the upper position of the swing range. The rod end portion 20a is held and is pulled out by the link 21. To use the spraying device 1, first, the cap 17 is removed, water or a chemical is injected into the tank 2, and then the cap 17 is firmly attached and the pedal 7 is stepped on. As a result, the cylinder holding rod 25 swings downward and the link 21 also swings downward.

Therefore, the sliding piece 32 is attached to the guide elongated hole 31.
Moving rearward along the rod end 2 of the cylinder 20.
0a comes to be pushed. This allows cylinder 2
Air is pumped from 0 to the tank 2. When the depression of the pedal 7 is stopped, the cylinder 20 swings upward again by the spring 22, at which time air is sucked into the cylinder 20 and stands by for the next pressure feeding.

When the inside of the tank 2 reaches a predetermined pressure by repeatedly depressing the pedal 7 as described above, by opening the injector 3 (see FIG. 4) toward the target object,
The water, the medicine or the like in the tank 2 can be continuously sprayed for a predetermined time. The shape of the tank 2 and the shape of the casing 10 are merely examples, and are not limited in any way.

7 to 13 show a spraying device 1 according to the present invention.
In the second embodiment, not only the casing 10 (base body 11 and cover body 12) is made of resin, but the tank 2 is also made of resin. Therefore, the following 5 is applied to the first embodiment.
It has one improvement. First, the first improvement is that in the tank 2, as shown in FIGS. 8 and 9, a width stop rod 50 that penetrates the tank 2 in the left-right direction is provided at the center of the body.

The width stop rod 50 has a bolt 51 having a length substantially corresponding to the lateral width dimension of the tank 2, a sleeve 52 externally fitted to the bolt 51, and a diameter arranged at both ends of the sleeve 52. It has a large washer 53 and a nut 54 screwed onto the bolt 51. Further, the tank 2 is provided with a water blocking cylinder portion 58 at a portion where the width stop rod 50 penetrates. The water-blocking tubular portion 58 encloses the width stop rod 50 so that both side walls of the tank 2 are recessed in a conical tubular shape toward the side walls of the other side, and both tubular shapes are formed at a substantially central position in the tank 2. The parts communicate with each other. The tubular interior of the water blocking tubular portion 58 and the interior of the tank 2 do not communicate with each other, that is, the water blocking tubular portion 58 has a hole penetrating left and right in the body portion of the tank 2. It is supposed to be composed.

A circular recess 60 into which a washer 53 can be fitted at both ends of the water-blocking tubular portion 58 and which can accommodate the wall thickness of the washer 53 and the bolt head of the bolt 51 or the nut 54. Are formed. To attach the width stop rod 50 to the tank 2, for example, first, the sleeve 5 is attached to the water-blocking tubular portion 58.
2 are inserted, then washers 53 are fitted into the circular recesses 60 on both end sides, and the bolts 51 are inserted into them in a skewered shape. Then, the nut 54 is screwed into the bolt 51.
By doing so, it is possible to prevent both side walls of the tank 2 from expanding (deformation of the tank 2 into a middle bulge) due to an increase in internal pressure.

Since the tank 2 does not spread laterally, the side wall of the tank 2 and the cylinder 20 (cylinder holding rod 25) do not come into contact with each other. This is also permanently maintained. Therefore, the cylinder 20 (cylinder holding rod 25) can be designed to be close to the side wall of the tank 2, and there is an advantage that the size increase of the spraying device 1 can be suppressed and the capacity of the tank 2 can be increased as much as possible.

Since the width stop rod 50 (particularly the bolt 51) is shielded from the water or the chemicals in the tank 2 by the water shield cylinder portion 58, corrosion or the like is less likely to occur. Therefore, it is possible to prolong the service life, and it is not necessary to use an expensive corrosion-resistant material for the bolt 51 and the like. In addition, width stop rod 5
0, the above configuration is not limited. For example, although not shown in the drawings, the bolts 51 may be simple rods, and retaining pieces (wedges, split pins, etc.) that come into contact with both side walls of the tank 2 may be provided at both ends thereof.
Of course, the sleeve 52 and the washer 53 can be unused.

Further, when the water blocking cylinder portion 58 is provided in the tank 2, it is also possible to adopt a structure in which a cylindrical portion is extended from one side wall to the other side wall. This water blocking cylinder 5
It is also possible to adopt a configuration in which 8 is not provided (that is, the width stop rod 50 crosses the inside of the tank 2). Second point of improvement
In the casing 10, the base body 11 and the cover body 12 have a structure that can be coupled by hook engagement, and this coupling is performed at once by a nut member 65 attached to the inlet port 2a of the tank 2.

That is, as shown in FIGS. 8 and 9, the base body 11 is erected outwardly at predetermined positions along its outer peripheral portion (see reference numeral 67 in FIG. 7 (total of 8 positions)). Hook pieces 68 are integrally provided, and on the other hand, the cover body 12 is integrally formed with an engagement recess 69 at a position corresponding to each hook piece 68. Further, as shown in FIG. 10, a male screw portion 72 is formed on the outer peripheral surface of the injection port portion 2a provided in the upper portion of the tank 2 so as to project upward. The male thread 72 has a base body 11
After the cover body 12 is covered with respect to the (tank 2), the nut member 65 is screwed to the portion protruding from the top hole 12 a formed in the upper portion of the cover body 12.

The nut member 65 has a flange portion 73 projecting outward on the outer periphery of the lower portion thereof. Therefore, when the nut member 65 is screwed into the injection port portion 2a, the cover body 12 can be pushed down strongly and stably via the flange portion 73. The pressing force of the nut member 65 enables the base body 11 and the cover body 12 to be coupled (that is, the hook piece 68 and the engagement recess 69 to be engaged) at once.

Therefore, the cover body 1 for the base body 11
There is an advantage that the assembly of 2 is extremely easy and light. Further, since the nut member 65 is in a state of being strongly pressed against the cover body 12, the cover body 12 is less likely to be flooded from the outside. Note that the nut member 65 can also have a structure that also serves as the cap 17 that is screwed into the water injection port 2a of the tank 2.

In connecting the base body 11 and the cover body 12, the number and arrangement of the hook pieces 68 and the engaging recesses 69,
The detailed shape is appropriate, and the relative relationship between the hook piece 68 and the engagement recess 69 (the cover body 12 side is the hook piece 68 and the base body 11 side is the engagement recess 69) and the coupling procedure (the hook piece 68 and The engagement recess 69 and the nut member 65 may be previously fitted by hand, and then the nut member 65 may be tightened.

The third improvement is that, as shown in FIGS. 7 and 8, the pivot shaft 29 of the link 21 for restricting the swing of the cylinder 20 (cylinder holding rod 25) and the upper end holding portion 7 of the spring 22.
6 is held in the tank 2 via mounting aids 78 and 79, respectively. Link 21
The attachment assisting tool 78 for holding the pivot 29 is formed in a U shape so as to sandwich the upper portion of the tank 2 from the left and right (see FIG. 9), and the pivots 29 are provided on both sides thereof. There is.

The mounting aid 78 is sandwiched and held between the upper surface of the tank 2 and the ceiling surface of the cover body 12 when the cover body 12 is mounted on the base body 11. The tank 2 is provided with a fitting recess 80 (see FIG. 10) for immovably holding the attachment assisting tool 78. On the other hand, the attachment assisting tool 7 that holds the upper end holding portion 76 of the spring 22
Reference numeral 9 is a rod-shaped member that crosses the upper portion of the tank 2 in the left-right direction, and spring-hanging pieces 81 are provided at both ends thereof.
The tank 2 is also formed with a fitting recess 82 for holding the mounting aid 79 immovably.

Since these attachment aids 78 and 79 are provided, an excessive load due to the link 21 and the spring 22 is applied to the tank 2.
The tank 2 can be protected without directly acting on the side wall of the tank. This allows the tank 2
Can be prevented from being damaged. Since the tank 2 is made of resin, the outer shape thereof has a degree of freedom, and the fitting recesses 80 and 82 as described above can be easily formed.

The fourth improvement is the structure which makes it easy to attach the tank 2 to the base body 11. That is, as shown in FIGS. 8, 9, 11, and 12, the tank 2 is formed in a shape in which the central portion in the left-right direction of the lower surface is bulged downward, and accordingly, the base body 11 is also formed in the tank 2. The lower bulge is formed in a structure that can be fitted. Therefore, the tank 2 can be laterally positioned with respect to the base body 11.

Further, a triangular plate-shaped fixing piece 85 is projected forward on the front side of the tank 2, and a positioning rod 86 is projected backward on the rear side of the tank 2. And
Accordingly, the base body 11 is provided with a retaining ring 88 for receiving the positioning rod 86 near the rear portion thereof, and with a holding piece 89 for receiving the fixing piece 85 near the front portion thereof. Therefore, if the tank 2 is placed on the base body 11 while inserting the positioning rod 86 of the tank 2 into the retaining ring 88 of the base body 11, the fixing piece 85 of the tank 2 is inevitably placed in the holding piece 89 of the base body 11. It will fit. Therefore, the split pin 90 is inserted into the sandwiching piece 89 and the fixed piece 85 in a skewered manner to open the leg.

As described above, the tank 2 can be positioned and attached to the base body 11 without any screwing or adhesion, and the assembling thereof can be extremely simple and quick. The fifth improvement is shown in FIGS. 7 and 8.
As shown in FIG.
The point is that a grip 93 protruding by the mold stay 92 is provided. As a result, the spraying device 1 as a whole can be handled more easily.

By the way, in the second embodiment, the hand-held injector 3 as shown in FIG. 13 (the injection nozzle is not shown in the drawing, but the reference numeral 94 is a male screw portion for mounting thereof) is adopted. This hand-held injector 3 is provided with a water pipe 96 having a water shutoff valve 95, and a rectangular box-shaped grip half body 9 from both left and right sides thereof.
7,98 are covered and combined. In the water pipe 96, 99 is a grip half 97, 9
The fins are used for positioning within 8 and for preventing rattling.

The grip halves 97, 98 form a rectangular opening 100 by connecting them, and hold the operation lever 101 swingably therein. The inner surface of the operating lever 101 is the water shutoff valve 9
5 is in contact with the spindle 102, and the operating lever 101
Engaging piece 103 projecting from one end (left end in FIG. 13) of the
Engages with the inner surface of one end of the opening 100. Further, at the other end of the operating lever 101, a hook portion 108 that can engage with dowel pins 105 and 106 that project from the inner side surfaces of the grip halves 97 and 98 so as to face each other is provided.

Therefore, the operating lever 101 can swing the hook portion 108 side with the engaging piece 103 as a fulcrum, and this swinging enables the water stop valve 95 to be opened. (Returning of the rocking follows the self-returning action of the water shutoff valve 95). A slide piece 110 having an operation portion (not shown) exposed to the outside is slidably held on one grip half body 97, and the operation lever 101 is swung (that is, A hook leg 112 is provided which can be engaged with the slide piece 110 when the water shutoff valve 95 is opened.

Therefore, in the hand-held injector 3, the operating portion of the slide piece 110 is operated while the operating lever 101 is swung, so that the operating lever 101 swings, that is, the water stop valve 95 is opened. Can be maintained as is. Therefore, the grip (grip half 9
(7,98) has the advantage that it is not necessary to hold it.

[0047]

According to the present invention, which has the above-mentioned structure, air can be pressurized and filled into the tank by stepping on the pedal held in the front portion of the tank. Therefore, the operator can perform the operation while standing upright (without being depressed and bending).
Therefore, anyone can perform air pressure filling easily and lightly.

Since the base body supporting the tank is formed with a notch corresponding to the area directly below the pedal, mud and water droplets attached to the feet do not enter the base body. Therefore, it is possible to prevent the pump device or the like from being broken or the tank from being rusted. Further, since the grounding portions are provided on both the left and right sides of the cutout portion, the pedaling force on the pedal can be firmly supported and the stability is enhanced. Therefore, the spraying device does not rattle or fall when the pedal is depressed.

The tank is formed by making the best use of the space on the base body so as to fill the space between the vertical movement locus of the pedal and the fulcrum near the rear part, without making the tank tall. A predetermined capacity can be secured. Therefore, stability can be improved. If a cover body is provided on the base body that has foot insertion guides that sandwich the vertical movement path of the pedal from both sides, the position where the pedaling force acts on the pedal can be made constant and stability is improved. It is possible to prevent the foot from slipping off and to prevent the foot from slipping off.

In the case of providing the cover body for covering the tank on the upper portion of the base body, the following is made in order to simplify the coupling structure of the base body and the cover body and to perform the coupling easily. That is, in the upper part of the tank, an outer peripheral surface is provided with an injection port part having a male screw part and protruding upward, and the cover body is provided with a top hole that matches the injection port part of this tank. Then, after the cover body is placed on the base body, the nut member is screwed into the inlet port of the tank protruding from the top hole of the cover body. As a result, the cover body is pushed down with respect to the base body, and the both are engaged and held.

By adopting this structure, the connection between the base body and the cover body can be performed very easily, reliably and quickly. Further, with the simplification of the structure, there is an advantage that the easiness of manufacturing and the manufacturing cost can be reduced. Further, since the nut member is strongly pressed against the cover body, it is difficult for the cover body to be flooded with water from the outside.
