Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for spraying powder or the like used in pollinating pollen or spraying chemicals, fertilizers, etc., and is particularly used as an attachment for a portable or portable power spreader. Suitable for.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, a backpack type power spreader 1 as shown in FIG. 5, for example, has been used for spraying powder or mist of pollen, chemicals, fertilizers or the like (hereinafter referred to as powder). In addition to the engine 2 as a power source, the power spreader 1 includes a fan for blower, a backrest (not shown), a chemical tank 4 for containing powder to be sprayed, a fuel tank 6 Etc., and the powder and the like in the medicine tank 4 are blown out from the blowout port 7 together with the air sucked from the outside.

Then, when the powder or the like is sprayed using the power sprayer 1, the powder or the like to be sprayed is put in the medicine tank 4, and the outlet 7 of the power sprayer 1 is used. The spraying device 9 is connected to the via a bellows type connecting tube 12. The spraying instrument 9 is composed of a relatively long and straight cylindrical direct injection pipe 15 and a nozzle 20 detachably attached to the tip of the direct injection pipe 15. The jet nozzle 20 is generally called a fan-shaped jet nozzle, and has powder and the like sent from the power spraying machine 1 through the connecting pipe 12 and the direct injection pipe 15 together with air at the tip thereof. As shown by the broken line in the figure, the nozzle 20a blows out toward the front obliquely downward so as to form a fan shape when viewed from the side.

[0004]

[Problems to be solved by the device]

 In the above-described conventional spraying device 9 composed of the direct injection pipe 15 and the spray head 20, since the posture of the spray nozzle 20 cannot be changed with respect to the direct injection pipe 15, the spraying direction (direction To change the direction, it is necessary to change the posture of the direct injection pipe 15 itself. In this case, the base side of the direct injection pipe 15 is connected to the power spreader 1, and since the direct injection pipe 15 is relatively long, the injection nozzle 20 is positioned higher than the chest of the worker. In order to look down, the base side of the direct injection pipe 15 must be lifted higher than the operator's chest, which is troublesome.

To explain this more specifically, for example, when pollinating a tall tree such as pears and apples, which is relatively tall, the pollen to be pollinated and the extender are mixed in an appropriate ratio. It is required to sprinkle other things (hereinafter referred to as pollen, etc.) down the flowers. Therefore, in order to spray pollen or the like on a flower located higher than the chest of the worker using the conventional spraying device 9, the spout 20 is positioned above the flower and It is necessary to lift the base side of the direct injection pipe 15 so that the injection port 20a faces downward and rotate the entire instrument 9 within the vertical plane. In this case, the base side of the direct injection pipe 15 is connected to the power spreader 1 as described above, and since the direct injection pipe 15 is relatively long, the entire instrument 9 is lifted up within the vertical plane. It is extremely difficult to rotate with. Further, in the case of the instrument 9, there may be a case where it is difficult for the nozzle 20a to take the necessary posture and position due to the obstacles such as tree branches.

[0006] Therefore, conventionally, pollen and the like cannot be properly sprayed, and a large amount of waste may be wasted, so that such pollination work is often difficult. As described above, with the conventionally used spraying device 9, it is difficult to spray powder or the like onto a relatively high portion, and the spraying efficiency is poor, and the powder or the like is wasted. In some cases, it is difficult to change the posture of the injection nozzle, so that it may not be possible to spray powder or the like to a desired portion.

In view of the above point, the present invention can spray the powder or the like so that it can be blown down to a relatively high portion as well, can prevent the waste of the powder or the like, and improve the spraying efficiency. It is an object of the present invention to provide a device for spraying powder or the like, which can be easily and surely sprayed onto a desired site and has a simple structure and can be provided at low cost.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the device for spraying powder or the like according to the present invention does not need to move the base side of the direct injection pipe, and only the injection head arranged on the head can be easily moved in a desired direction. It is something that can be directed. Specifically, a flexible pipe is attached to the tip of the direct injection pipe connected to the power sprayer, and a jet nozzle having a nozzle for spraying powder and the like in a specific direction is connected to the tip of this flexible pipe. In addition, the angle adjusting rod is swingably connected to the outer circumference of the jet nozzle.

The spraying device of the present invention is particularly suitable for being used as an attachment to a power sprayer when pollinating a tall tree such as pears and apples. Needless to say, the present invention is not limited to such usage forms, but can be used for spraying various other powders and the like. As the flexible pipe, known flexible pipes, tubes, and hoses such as a bellows type flexible pipe, a flexible metal pipe, and a hose made of an elastic material such as rubber can be used. It is more preferable to use the one which is straight in its natural state and automatically returns to its original straight state when released after being bent or bent by applying an external force.

Further, the connection form between the nozzle and the angle adjusting rod may be one in which the angle adjusting rod is simply attached to the nozzle by a pin or the like, or various universal joints or spherical bearings are used to adjust the angle. The rod may be made to freely swing in any direction.

[0011]

[Action]

 In the device for spraying powder or the like according to the present invention configured as described above, the direct injection pipe and the nozzle head are connected by the flexible tube, and the angle adjusting rod is swingably connected to the nozzle head. Since the base side of the direct injection pipe is held by one hand, the flexible pipe can be bent in any direction by pulling, pushing or turning the angle adjusting rod with the other hand. It is possible to freely change the position of the injection head with respect to the direct injection pipe without having to change the position of the injection pipe.

[0012] Therefore, it is possible to easily direct the spray head so as to look down at a site higher than the chest of the worker, and, for example, when pollinating a relatively tall standing tree such as pears and apples. Can be sprayed down from above the flower, and by operating the angle adjustment rod to swivel or raise only the spout, conventional conventional spraying equipment that is totally straight can use tree branches, etc. Even if it is difficult to get the required posture and position due to the obstacles, it is possible to spray the powder etc. to all the desired parts, and the spraying range can be adjusted without moving the direct injection pipe. It can be expanded.

Further, if the free end side of the angle adjusting rod is fixed by an appropriate locking means such as a hook, powder or the like can be continuously sprinkled in a fixed direction. Therefore, when the spraying device of the present invention is used, it is possible to easily carry out the work of spraying the powder or the like, which has been difficult in the past, so that the powder or the like is blown down to a relatively high portion. It is possible to prevent waste and improve the spraying efficiency, and it is possible to spray the powder or the like easily and surely on a desired part.

Further, in the spraying device of the present invention, most of the parts thereof can be composed of commercial products and diversion parts of the existing spraying device, so that there is an advantage that it can be easily manufactured at low cost.

The connecting part is hermetically sealed. Further, the flexible pipe 25 is straight as shown in FIG. 1 in a natural state, and has an appropriate degree of straightness when it is released after being bent or bent by an external force and then released. The one with elasticity is adopted.

Further, the injection nozzle 20 has a double pipe structure in which a connecting tubular member 27 is externally fitted and fixed to the outer periphery of the tubular passage portion 20b (FIG. 3), and the outer periphery of the connecting tubular member 27 is The tip portion 31 of the angle adjusting rod 30 is connected to the portion via a swing connecting portion 35. For example, as shown in FIG. 3, the swing connecting portion 35 is configured such that the male screw portion 41 of the bolt 40 is screwed in the thickness direction of the connecting tubular member 27 so that the tip end portion 31 of the angle adjusting rod 30 is fixed to the bolt. It has a very simple structure in which it is pivotally supported by a cylindrical shaft portion 45 on the head side of 40, and a slide washer 43 is provided between the head of the bolt 40 and the tip 31 of the angle adjusting rod 30. Further, ring spacers 42 are respectively interposed between the tip end portion 31 of the angle adjusting rod 30 and the connecting tubular member 27, and the angle adjusting rod 30 extends in the direction along the central axis of the injection nozzle 20. It can be rocked.

A spherical bearing may be used as the swing connecting portion 35. In this case, for example, as shown in FIG. 4, the lower portion of the spherical bearing 36 having a two-divided configuration is embedded in the connecting tubular member 27, and the spherical body 37 having the connecting pin 38 protruding therefrom is supported, and When the tip end 31 of the angle adjusting rod 30 is fixed to the connecting pin 38 with the nut 39, the angle adjusting rod 30 can be swung freely and smoothly in any direction as shown by the chain line in FIG. Can be made.

Can be changed.

Therefore, as shown in FIG. 2, for example, it is possible to easily orient the spout 20 so as to look down at a portion higher than the chest of the operator, for example, a pear or an apple. When pollinating tall tall trees, it is possible to sprinkle pollen from above the flowers, and operate the angle adjusting rod 30 to turn only the spout 20 described above. Even if it is difficult for the conventional spraying device 9 having a straightness to be lifted up to take a necessary posture and position by being obstructed by a tree branch or the like, the spraying device 10 of the present embodiment is desired. It is possible to spray the powder or the like on all of the parts, and it is also possible to widen the spraying range without having to largely move the direct injection pipe 15.

Further, if the free end side of the angle adjusting rod 30 is fixed to the machine body side by an appropriate locking means such as a hook, the powder or the like can be continuously sprinkled in a fixed direction. . Therefore, when the spraying device 10 of the present embodiment is used, it is possible to easily carry out the work of spraying powder and the like down to a relatively high portion, which has been difficult in the past, and to perform the operation of powdering. The waste efficiency of the body and the like can be prevented, and the spraying efficiency can be improved, and the powder and the like can be sprayed easily and surely to a desired portion.

Further, since most of the parts of the spraying device 10 can be composed of commercial products and diversion parts of existing spraying devices, there is an advantage that they can be easily manufactured at low cost.
