Description

  The present invention relates to a frost-proof fan used in orchards, tea gardens, and other fields, or a frost-proof fan that is preferably used in pasture fields, rice straw / wheat straw outdoor manufacturing plants. The purpose is to prevent contamination of trees, fruits, leaves, rice straw, wheat straw, etc., for example, to wipe away harmful substances such as radioactivity, smoke, dust, etc., or to humidify, cure, or prevent frost. Intentionally, a frost-proof fan (a frost-proof fan installed in the air or on the ground) that injects water, chemical liquid, liquid fertilizer, insect repellent fluid and fluid particles or fluid fine particles. (This frost-proof fan is an idea including a fan).

  In recent years, the prevention of contamination of rice straw, wheat straw, etc. due to radiation has become a major problem in pasture grass, rice straw and wheat straw outdoor factories. As a countermeasure against this contamination, there is room for utilization of a frost-proof fan sprinkler used in orchards and farm fields. Similarly, prevention of contamination of trees, fruits, branches, leaves and the like due to radioactivity in orchards and farm fields is a major problem. And this kind of contamination caused by radiation has caused domestic warfare.

  Therefore, in order to overcome this situation, for example, it is extremely effective to eject a relatively large amount of water, chemical liquid, liquid fertilizer, insect repellent fluid and fluid particles or fluid fine particles. However, there is currently no effective solution. The same applies to other harmful substances such as smoke and dust.

  There is no appropriate means (watering device) for solving such a situation, even in the prior art starting from the prior art, but as a related invention, a frost-proof fan and fine fog cooling are combined. There are combined technologies. For example, the invention of the “fine fog cooling device for controlling the growth of agricultural products” proposed in Japanese Patent Application Laid-Open No. 2010-68740 proposed by the present applicant, ) And a defrosting method using the high altitude fan. It can be appreciated that these inventions are beneficial. However, the present invention intends to use a combination of a watering nozzle and a fan, spray water particles, and wipe off harmful substances such as radioactivity, smoke, and dust from a relatively large amount of water. It is thought that it is not.

  In addition, for example, the following documents can be found as other fields related to watering. Document 1 includes “Decontamination method and apparatus” of JP-A-2002-357695. However, in this specification [0066], there is a description that the spray device is installed in the decontamination tank and the decontamination liquid or washing water is sprayed on the decontamination target. However, specifically, with a fan and a watering nozzle intended by the present invention, objects such as trees, fruits, branches, leaves, or rice straw / wheat straw are prevented from being contaminated by radioactivity and other pollution. Does not aim at decontamination with harmful substances such as smoke and dust, or does not sprinkle water, chemicals, liquid fertilizers or insect repellent fluids. Moreover, the literature 2 has "the purification method of contaminated soil" of Unexamined-Japanese-Patent No. 2004-243195. However, in the present invention, in the specification [0010], sprinkling is effective to calm the soaring dust. In the present invention, the sprinkling effect is exhibited by using superheated steam as a heating source. In other words, the superheated steam is cooled and returned to the water, the steam mixed with the dust returns to the water, adsorbs the dust and falls as water droplets to prevent the dust from scattering, There is a description that it is recovered. However, this document 2 also has the same improvement as document 1.

  First, a preferable example of the defrosting fan A common to each embodiment will be described. This defrosting fan A (which may be a normal fan) is a ceiling that fits on the building pillar B (support material). A cylindrical mounting cylinder 1 provided with: a fastening screw 2 provided in the mounting cylinder 1 for fastening the mounting cylinder 1 to the building pillar B; and a mounting base having a substantially ship shape provided on the upper surface of the mounting cylinder 1 3, a motor 5 having a speed reduction mechanism built in the mount 3, a swinging means C (turning) composed of a link mechanism 6, and a movable shaft 600 (turning within a certain range) of the swinging means C. A rotating base 7 provided on the base 7, a motor base 8 provided on the base 7 so as to be adjustable at a depression angle via a depression angle adjusting means D provided on the base 7, and a protection provided on the motor base 8. It is comprised with the motor 11 which rotates the blade | wing 10 for frost fans.Therefore, the blade 10 is rotated by the rotation of the motor 11, and the gantry 7 swings with the swinging means C and the movable shaft 600, so that the swing range (in FIG. ), The air blowing area F (air blowing flow area) shown in FIGS. 5 and 12 is formed through the rotation of the blade 10. Further, the depression angle of the blowing area F (the depression angle D1 of the defrost fan A shown in FIGS. 5 and 12) is adjusted via the depression angle adjusting means D. As described above, it can be installed on a conventional frost-proof fan (not shown), and low cost and versatility are improved, expenses are reduced, management is simplified, and conventional experience can be utilized. There are features.

  In the figure, reference numeral 12 denotes a guard for the anti-frost fan, which is installed on the rear side of the blade 10 and surrounds the blade 10 from the rear side of the blade 10. The front side of the blade 10 is open 1200. Therefore, the guard 12 is used for a new work of preventing the broken blade 10 from scattering backward (spattering backward is approximately 100%), avoiding the occurrence of the accident, or checking or adjusting the spray nozzle. On the basis of the inspection of the water nozzle, especially in the case of a farm worker who is not accustomed to the water nozzle or its device, avoiding accidents involving people and flying objects that are likely to occur, extra work related to this (for example, This is useful for measuring avoidance and the like of fixing the blade 10 so that it does not rotate in a natural wind, monitoring work, and the like. In the present invention, the guard 12 has other useful roles as described later.

  In the first embodiment shown in FIGS. 1 to 5, the net-like guard 12 that is annular and has a suction gap is larger in diameter than the outer peripheral surface of the motor 11 attached to the output side of the motor 11. A large number of substantially half-turned U-shapes are provided with their base ends sequentially arranged in the disc direction at intervals in the disc direction of the disc-shaped mounting plate 1100 and their free ends provided on the open 1200 side. A guard flat plate 1201 and a plurality of ring-shaped guard frames 1202 extending from the base end toward the opening 1200 side and extending from a small diameter to a large diameter orthogonal to the large number of guard flat plates 1201.

  In the figure, reference numeral 15 denotes a watering nozzle provided on the building pillar B or another pillar, and the watering Y (water discharge) from the watering nozzle 15 is generated by the blade 10 (frost protection fan A) as shown in FIG. Injecting toward the center X1 of the overlapping region X of the swivel region E and the air blowing region F by swinging, for example, diffused in this overlapping region X, and then diffused from this overlapping region X It is carried toward the front-end | tip F1 of the ventilation area | region F in a state. As a result, it is considered that harmful substances remaining in the tree G, fruit G1, leaves G2, rice straw, wheat straw, etc., such as radioactivity, smoke, dust, etc. can be wiped out. Water spray Y sprays water, water particles, or fine particles. For example, as shown in FIG. 14, rain dew sprinkler, shower sprinkler, direct spray sprinkler, diffusion sprinkler, or spray sprinkler. As shown in FIG. 15, the rain dew sprinkling and direct water sprinkling are considered to be beneficial for wiping off the harmful substances. Moreover, it is thought that humidification, curing, frost prevention, etc. of trees G, fruits G1, leaves G2, etc. can be achieved by shower watering and spray watering. A hose 16 is connected to the watering nozzle 15, and a pump is provided on the hose 16 (not shown) to supply a predetermined amount (relatively large amount) of water to the watering nozzle 15. Further, the operation of the watering nozzle 15 can be remotely operated.

  In the figure, reference numeral 20 denotes a moving means, and the moving means 20 has a structure for supporting the watering nozzle 15 and receiving the forward and backward movement of the watering nozzle 15. A preferred example of the moving means 20 will be described below. The pair of belts 21 and 21 that are fitted to the pillar B (including other pillars) are provided with the upper and lower end flange pieces 22a and 22a penetrating or latched, and the building pillar B (pillar) A channel-shaped main body 22 provided in the longitudinal direction B1, a set screw 23 penetrating and screwed into the main body 22, and a long groove 25 through which a shaft portion 23a of the set screw 23 is passed, and an end portion A pair of hook-shaped pieces 26a bent in the form of a plurality of locking notches 27, and a channel-shaped support body 26 slidably provided at a distance 28 between the main body 22 and the belt 21. . And it is the longitudinal direction 26b of the support body 26 to the long groove 25 and the collar piece 26a. In addition, the main body 22 and the support body 26 are provided to cross each other, and this cross state is secured via the set screw 23. The slide, that is, movement of the support 26 in the longitudinal direction 26b will be described. The set screw 23 is screwed back, and the notch 27 of the support 26 is separated from the flange middle part 22b of the main body 22. By this operation, the support body 26 is released from the fixing relationship of the main body 22, so that the support body 26 can be moved forward or backward using the long groove 25 and using the set screw 23 as a guide. And although it mentions later, since the watering nozzle 15 is provided in this support body 26, it can advance or retreat together. When the set screw 23 is screwed (tightened) after the support body 26 is moved forward or backward, this time, the support body 26 is attracted to the main body 22 side, and the notch portion 27 is the middle portion of the main body 22 piece. It bites into 22b and its position is determined. Note that the head of the set screw 23 is within the interval 28 and has a gap 28 a between the belt 21. Accordingly, the gap 28a is used to move forward and backward.

  In the figure, reference numeral 30 denotes a movable means (same as the depression angle adjusting means D) of the watering nozzle 15 and also serves as an attaching means to the support 26. An L-shaped movable plate 32 pivotally attached to the tip 26c of the support 26 via a shaft 31 and an L-shaped inclined bent plate portion 32a of the movable plate 32 are provided with a watering nozzle 15 and a movable plate. A tightening screw 35 provided on the movable plate 32 and the support 26 is penetrated through the half-moon groove 33 established at 32. Accordingly, the loosening of the tightening screw 35 causes the movable plate 32 to move along the half-moon groove 33 with the shaft 31 as a fulcrum, and the tightening screw 35 is fastened and fixed at the movable position. Thereby, the injection direction of the watering nozzle 15 is changed.

  Further, in this example, the belt 21 fitted to the building pillar B described above is supported by the main body 22 between the pair of belts 21. A number of through holes 2100 are formed in the belt 21, and hook bolts 2101 that are inserted into and locked in the through holes 2100 are provided at one end of the belt 21. Therefore, after the belt 21 is mounted on the building pillar B, one end portion is overlapped with the other end portion, and both the through holes 2100 are combined, and the combined through hole 2100a is connected to the hook bolt 2101. It is a structure that inserts and fixes nails. Therefore, the fitting length of the belt 21 can be adjusted using the tightening and loosening of the hook bolt 2101. Using this adjustment, the belt 21 can be moved to an appropriate position of the building pillar B, and at the same time, the vertical position of the water spray nozzle 15 can be changed in the longitudinal direction B1 of the building pillar B. This movement can be used comprehensively by the forward and backward movement of the watering nozzle 15 by the moving means 20 and the angle change by the movable means 30.

  Therefore, the relationship between the spraying direction of the watering nozzle 15, the swirling region E, and the air blowing region F will be described with reference to FIGS. 5, 12, and 13. First, as shown in FIG. 13, the air flow area F (air blowing direction) by the defrost fan A is substantially fan-shaped when viewed in plan, but substantially overlaps the swirl area E of the defrost fan A. Accordingly, it is necessary that the fluid jet from the water spray nozzle 15 also be in the air flow area F and the swirl area E. Therefore, by making full use of the vertical movement of the moving means 20, the movable means 30, and the belt 21, the watering nozzle 15 is moved forward or backward, and for example, an appropriate elevation angle with respect to the field scene. , Horizontal angle or depression angle. The injection direction is selected using such an operation and structure. For example, the spraying direction of the watering nozzle 15 is in the blowing area F and toward the center position of the turning area E (the turning area E and the center X1 of the overlapping area X of the blowing area F). Is ideal, and in FIG. 13, it has a substantially fan shape in plan view. Further, as shown in FIG. 5 or the like, it is desirable to inject toward the center F1 of the air blowing region F in a side view. Thereby, as described above, the structure is diffused in the superimposing region X, and then transported from the superimposing region X toward the tip F1 of the blowing region F in a diffused state, and includes a tree G, a fruit G1, and a leaf. It is conceivable that harmful substances can be wiped off from G2 and the like, and that the trees G, fruits G1, leaves G2, etc. can be humidified, cured, or defrosted.

  Although not shown, there may be an example in which a fluid such as a chemical solution, liquid fertilizer, insect repellent, or other liquid is used instead of water. In this case, spraying water after spraying the fluid such as the chemical solution and the insect repellent is also beneficial for sanitation and wiping away the chemical solution and the insect repellent.
