TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a backpack type sprayer for spraying powdery or granular materials such as agricultural chemicals and organic fertilizers, and more particularly to a sprayer for smoothly supplying powdery or granular materials to be sprayed.
[0002]
[Prior art]
A conventional backpack type powdery and granular material disperser includes a storage unit formed of a cloth bag having an opening, a folding frame for fixing the periphery of the opening of the storage unit, and a strap suspended from the frame. And a discharge tube attached to the bottom of the storage unit in communication with the bottom of the storage unit. The release tube is mounted on a side surface near the bottom of the storage unit via a rubber bellows, A spray nozzle is detachably attached to the apparatus (see Patent Document 1).
[0003]
When using the above-mentioned powdery and granular material sprayer, a pesticide or an organic fertilizer is stored in a storage part, and the pesticide or the like is discharged and sprayed from a spray nozzle provided at a tip of the discharge pipe. In order to uniformly spray the pesticides and the like discharged from the nozzles at appropriate locations, the farmer moves the farmland while swinging the discharge pipe left and right. When the discharge tube is swung right and left, a rubber bellows (bent portion configured to be freely bendable) is provided to make the angle of the discharge tube free.
[0004]
However, in order to spray the pesticides and the like stored in the storage unit smoothly, it is necessary to continuously supply the pesticides from the storage unit to the discharge pipe. The amount available was not constant. This is because pesticides or organic fertilizers to be sprayed on agricultural land include powdered ones in addition to those processed into pellets. Although it is possible to continuously supply approximately the same amount of pesticides, etc., powdered pesticides, etc., have low fluidity and cannot supply a continuous constant amount to the discharge pipe. If a large amount of pesticide temporarily flows into the discharge pipe, the pesticide may be clogged inside the discharge pipe. Therefore, a method of preventing stagnation of pesticides and the like inside the discharge tube by providing small holes in a part of the discharge tube has been adopted (see Patent Document 2).

[Problems to be solved by the invention]
However, the powdery pesticide and the like are not only in the inside of the discharge tube but also in the inside of the bellows (bent portion configured to be freely bent) or in the vicinity of the outlet provided at the bottom of the storage portion to which the bellows is connected. Agglomerates are formed, and the pesticides and the like are stagnated, so that not only the supply amount of the pesticides and the like is not stabilized, but also a situation in which the pesticides to be sprayed is not supplied to the spray nozzle occurs.
[0007]
In particular, in recent years, cultivation by organic agriculture is becoming popular, and organic fertilizers used for these are expensive in comparison to unprocessed organic fertilizers. The frequency of using organic fertilizers is increasing. In addition, a mixture containing magnesium and calcium called formic lime which is used as a neutralizing agent because of the necessity of soil improvement is a very fine powder. Was virtually impossible to spray.
[0008]
The present invention has been made in view of the above points, and an object of the present invention is to provide a sprayer that can continuously spray not only granular agricultural chemicals but also organic fertilizers and the like. .

In this case, since the connecting portion swings together with the pipe portion due to the bending of the bent portion, the projecting member supported by the connecting portion moves down the flow of the pesticide or the like stagnated inside the bent portion by swinging the pipe portion. Can be promoted.
[0013]
In the above case, the protruding member may be a protruding member that passes through the hollow interior of the bent portion and reaches the storage portion. Thereby, fluidity can be given not only to the bent portion but also to the pesticide or the like stagnating inside the storage portion, and the flow can be promoted.
[0014]
Further, the projecting member may be a substantially U-shaped projecting member formed by bending one rod-shaped member at the center, and both ends of the projecting member may be supported by the base end of the pipe portion. it can. Thereby, the support of the protruding member can be strengthened, and a configuration capable of withstanding a force acting laterally on the protruding member can be achieved.
[0015]
In this case, the vicinity of both ends of the protruding portion is bent, and both of the bent ends are directed in the radial direction of the pipe portion, and the main body of the protruding member is in a state substantially parallel to the axial direction of the pipe portion. Is preferred. Thereby, the vicinity of the bent both ends can make the main body portion of the protruding member have a predetermined interval from the inner surface of the pipe portion, and when the bent portion is linear, the main body portion of the protruding member becomes Since it is arranged near the center line of the bent portion, the projecting member can be present in a wide range according to the bending state of the bent portion.
[0016]
Further, the protruding member is formed by bending one rod-shaped member at the center to form two parallel bases, and bending a tip portion in an angle direction with respect to a plane including the two bases. The two ends are supported by the side surface of the pipe part, and the base part can be arranged in a state substantially parallel to the axial direction of the pipe part. Accordingly, even when an external force acts in a direction perpendicular to a plane including the two bases, the external force does not act in a rotating direction about both ends as an axis. can do.
[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present embodiment relates to a baggage type powder / granular material spreader 1 shown in FIG. 1, and the spreader 1 is provided with a bag-shaped storage portion 3 on a frame 2, and an upper portion of the storage portion 3. Are fixed to the frame 2 and both are integrally formed. A cylindrical pipe portion 5 is attached to the bottom of the storage portion 3 via a bent portion 4, and the frame 2 is provided with two straps 6. By hanging the strap on both shoulders, the storage unit 2 integral with the frame 2 can be carried. The bent portion 4 is made of rubber and can be bent freely, so that the tip of the pipe portion 5 can be freely directed to the location where the spraying is to be performed while carrying the storage portion 3.
[0018]
Here, in the present embodiment, as shown in FIG. 2A, a protruding member 7 is provided at a base end 51 of the pipe portion 5, and the protruding member 7 is separated from the base end 51 of the pipe portion 5. It protrudes toward the inside of the bent portion 4. Further, as shown in FIG. 2B, the protruding member 7 is formed by curving one rod-shaped member at the center, and forms a substantially U-shape having two parallel bases 71 and 72. At the same time, both end portions 73 and 74 are supported by the pipe portion 5. The two end portions (tip portions of the base portions 71, 72) 73, 74 are bent at right angles to the axes of the base portions 71, 72, and the tip portions 73, 74 extend in the circumferential direction of the pipe portion 5. By being supported so as to face each other, the axial directions of the bases 71 and 72 are arranged so as to coincide with the axial direction of the pipe portion 5.
[0019]
The cylindrical wall surface of the pipe portion 5 is provided with through holes 52, 53 penetrating in the circumferential direction. By inserting the tip portions 73, 74 of the base portions 71, 72 into the through holes 52, 52, Thus, the axial directions of the base portions 71 and 72 can be made to coincide with the axial direction of the pipe portion 5. Male threads 75, 76 are engraved on the tip portions 73, 74 of the base portions 71, 72, and nuts 77-82 can be screwed from both inside and outside of the pipe portion 5. It is. The distance from the inner surface of the pipe portion 5 to the bases 71 and 72 is adjusted by the positions of the nuts 77 and 78 screwed inward, and the inner nuts 77 and 78 are screwed by the outer nuts 79 to 82. Thus, the side wall of the pipe portion 5 is sandwiched between them, and thereby the projecting member 7 is supported.
[0020]
With the above configuration, as shown in FIG. 3A, the protruding member 7 protruding from the pipe portion 5 is arranged near the center line of the hollow inside of the bent portion 4. . And when rocking the pipe part 5 in order to spray a pesticide etc., the bending part 4 bends suitably between the storage part 3 and the pipe part 5 according to the rocking angle of the pipe part 5 concerned. On the other hand, the protruding member 7 is fixedly supported at the base end 51 of the pipe portion 5 and changes the angle according to the swing of the pipe portion 5. Therefore, when the pipe portion 5 swings, as shown in FIG. 3B, the protruding member 7 swings in the left-right direction relative to the inside of the bent portion 4, and the bent portion When a powdery agricultural chemical or the like forms a lump in the inside of 4, the lump can be crushed. As described above, by pulverizing the clumps that cause the stagnation of the powdery pesticide and the like inside the bent portion 4, the flowability of the pesticide and the like is improved, and the pesticide and the like are continuously supplied to the pipe portion 5. The pesticide and the like with improved fluidity can be supplied to the tip without stagnation even inside the pipe portion 5.
[0021]
Next, both end portions (tip portions of the base portion) 73 and 74 of the protruding portion 7 will be described in detail. As described above, both end portions 73 and 74 of the protruding portion 7 are bent in a direction perpendicular to the base portions 71 and 72 for attachment to the wall surface of the pipe portion 5. As shown in FIG. 4A, the distal end portions 73 and 74 can be formed on the same plane as a virtual plane X including the base portions 71 and 72 of the protruding member 7. When bent in this manner, the end portions 73 and 74 are supported in a state perpendicular to the wall surface of the pipe portion 5, so that the plane X matches the diametric direction of the cylindrical pipe portion 5, The end portions 73 and 74 are fixed to wall surfaces located on both sides in the diameter direction. Therefore, the axial direction of the bases 71, 72 of the protruding portion 7 can be adjusted by turning the ends 73, 74 around them. Then, by making this direction coincide with the axial direction of the pipe portion 5, the protruding portion 7 can be arranged near the center line of the pipe portion 5.
[0022]
Further, both end portions 73 and 74 of the protruding portion 7 can be bent so as to have angles α and β with respect to the plane X as shown in FIG. In this case, the tip portions 73 and 74 have predetermined angles α and β with respect to the plane X, but are bent at right angles to the axes of the base portions 71 and 72. . Therefore, by fixing the tip portions 73 and 74 perpendicularly to the axis of the pipe portion 5, the axial direction of the base portions 71 and 72 is constant, and the direction matches the axial direction of the pipe portion 5. . When a force acts in a direction perpendicular to the plane X, the tip portions 73 and 74 support the base portions 71 and 72, and the swinging of the pipe portion 5 causes the projecting portion 7 inside the bent portion 4. The support of the projecting member 7 can be strengthened irrespective of the relative swing direction of the projection member 7.
[0023]
Next, another embodiment will be described. In the present embodiment, as shown in FIG. 5, a cylindrical connecting portion 9 that can be arranged between the bent portion 4 and the pipe portion 5 is provided, and the connecting portion 9 is provided with the protruding member 7. It is. The outer diameter of one end 91 of the connecting portion 9 is large enough to be inserted into the end 41 of the bent portion 4, and the inner diameter of the other end 92 is large enough to allow the insertion of the pipe portion 5. The protruding member 7 is supported by the main body of the connecting portion 9 and almost entirely protrudes outward.
[0024]
Therefore, the connection portion 9 is mounted by inserting the one end 91 into the end portion 41 of the bent portion 4 while inserting the protruding member 7 into the hollow interior of the bent portion 4. The end 51 is inserted into the other end 92 of the connecting portion 9. According to the present embodiment, the projecting member 7 can be projected into the hollow inside of the bent portion 4 without providing the through-holes 52 and 53 (FIG. 2) in the pipe portion 5. For example, it can be easily exchanged when it is curved or its length is changed.
[0025]
Although the embodiments of the present invention are as described above, various modes can be adopted without departing from the spirit of the present invention. For example, as shown in FIG. 6, the protruding member 7 can be configured to be long enough to reach the storage unit 3. In this case, it is possible to promote the flow of the powdery pesticide or the like that stagnates near the connection between the storage portion 3 and the bent portion 4.
[0026]
In each of the above-described embodiments, the bent portion 4 is shown to be greatly curved. However, when the storage portion 3 is a cloth bag-shaped storage portion, in addition to the bent portion 4 being bent. The direction of the bottom outlet of the cloth bag-shaped storage portion may change in accordance with the direction of the pipe portion 5, whereby the bending of the bent portion 4 may be small. In such a case, by causing the projecting member 7 to reach the storage section 3, the effect of improving the fluidity when the pipe section 5 swings is exerted near the discharge port of the storage section 3.
[0027]
Further, in the above-described embodiment, the description of the nozzle provided at the tip of the pipe portion 5 is omitted, but various exchangeable forms of the nozzle can be used. For example, it is also possible to adopt a configuration in which all ends of the pipe portion 5 are opened. A plurality of through holes are provided in a wall surface near the end of the pipe portion 5, and an agricultural chemical or an organic fertilizer to be sprayed from the through holes. Can be discharged. It is also possible to mount a nozzle having a special shape or mechanism. Different types of nozzles are used depending on whether a pesticide or the like processed into a pellet having a large particle diameter is sprayed or a nozzle processed into a granule having a small particle diameter. Naturally, when spraying powdered agricultural chemicals or the like, a nozzle that does not cause clogging should be selected.
[0028]
【The invention's effect】
As described above, according to the present invention, even when spraying not only granular agricultural chemicals or organic fertilizers, but also powdery agricultural chemicals or the like, by improving the fluidity of the agricultural chemicals or the like stagnant in the storage portion or the bent portion. , The supply to the pipe section and the tip nozzle can be made smooth. Further, since the supply to the pipe portion and the tip nozzle becomes smooth, continuous spraying can be realized without stagnation of the pesticide or the like in the range up to the tip nozzle.
