Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an elevating type low place defrosting fan apparatus for a tea garden.
[0002]
[Prior art]
Conventionally, there is a defrosting fan disclosed in Japanese Patent Application Laid-Open No. 10-113076 as a document related to a multistage elevating type low place defrosting fan device. The present invention supports the blower body so as to be able to swing and adjust the depression angle via a connecting member rotatably provided at a support portion provided at the tip of the telescopic pole, The housing is folded by the ground side using the reduction of the pole and the rotation of the support part, and the work of the large machine is performed or facilitated through the housing of the blower body in the teacup. Or, to maintain the scenery of tea gardens, etc.
[0003]
[Problems to be solved by the invention]
In the above document, the pole is a telescopic and nested type, and the pole is moved up and down using a fluid such as water or air, and the connection pipe for supplying and discharging fluid is buried in the ground. Therefore, it is necessary to drill the hole for the pole and the hole for the connecting pipe. If the holes are drilled at the same time, the hole becomes large, and accordingly, there is a problem of securing a place for drilling or a large hole. There are problems such as time and labor required for drilling. In addition, with regard to the supply or discharge of fluid, the necessary equipment (pressor, pump, hose, etc.) or piping, transportation, water supply measures, human means required for frost-proof fan accommodation, cold measures, etc. Is necessary and is a problem. In addition, when there is a problem with the connection pipe, for example, when repairs, replacement of parts, etc. are necessary, it is necessary to dig up the soil or to take out parts from the ground, which takes time and labor. is there.
[0004]
Further, since the literature has a configuration in which the pole is telescopic and nested, the pole and the blower body may be rotated by the weight of the blower body when the pole and the blower body are lifted and lowered. Therefore, there are problems such as the possibility of damaging the tea plant near the pole, the anti-frost effect cannot be expected, or the danger. This document has a configuration without adjusting the tilt angle of the blower body. Therefore, there is a problem in dealing with slopes.
[0005]
Further, this document is a configuration in which the blower main body is accommodated by a folding operation of the support portion. Therefore, there are problems that various devices for plucking, disinfection, etc. cannot be used promptly, that quick setup and work cannot be performed, and that labor saving cannot be achieved.
[0006]
In addition, in the general structure defrosting fan marketed etc., it is the structure which performs the inclination depression angle adjustment of this defrosting fan in the place which remove | deviates from the support | pillar axial center vicinity. Therefore, an uneven load is applied to the support column, and the stability is impaired. In addition, the defrosting fan having a strut structure with a telescopic square column cannot be easily rotated. Therefore, there are problems that it is difficult to blow air toward a predetermined place in the tea garden and that the defrosting effect cannot be enhanced.
[0007]

[0012]
In order to reach the raised state of FIGS. 4 to 6 from the accommodated state of FIGS. 1 to 3, the winding motor accommodated in the cover and support body is operated (forward rotation), and the winding body is properly aligned. Roll and take up the wire one after another. The winding of the wire raises the third prism and tensions the other wires locked between the third prism and the first prism (the one side is pulled up sequentially). Therefore, the rising of the third prism and the second prism are performed substantially simultaneously, and when the third prism reaches the rising limit, the second prism is also at the rising limit, and just the anti-frost fan. Is installed on the teacup. After this installation, when it becomes close to the frosting state, the frost-proof fan is driven to blow air to the tea plant. In addition, means, such as a guide and a pulley, may be provided in a wire and another wire (hereinafter the same).
[0013]
To reach the accommodated state shown in FIGS. 1 to 3 from the raised state shown in FIGS. 4 to 6, the winding motor is operated (reversely rotated), the winding body is reversed and the wires are sequentially rewound. By the unwinding of the wire, the lowering of the third prism and the other wires locked between the third prism and the first prism are relaxed (substantially the whole descends). Therefore, the lowering of the third prism and the second prism is carried out substantially simultaneously, and when the third prism reaches the lowering limit, the second prism also becomes the lowering limit, which is just anti-frosting. A fan is housed in the teacup.
[0014]
In the examples of FIGS. 8 to 11, since the wire is locked between the winding body and the (n-1) th prism to the first prism, if the wire is sequentially wound via the pulleys 34, 36, etc. The nth prism to the second prism rise sequentially. This rise or the like is substantially the same as described above. Further, when the wires are sequentially rewound, the n-th prism to the second prism descend. This descent is substantially the same as described above.
[0015]
12 to 16 show an example of a turning device for turning the defrost fan. The slant depression angle adjusting plate is turned using a slot or the like provided in the inclination depression angle adjusting plate or the like, and the blowing direction (direction) of the defrosting fan is changed. For example, the stopper is relaxed and the tilt depression angle adjusting plate is rotated, and the relaxed stopper is tightened and fixed at this turning position. Thereby, the ventilation direction of a defrost fan is changed. Although not shown in the drawing, it can be swung by a defrosting fan mounting plate instead of the tilt depression angle adjusting plate.
