DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a tea plant (chaune)
The present invention relates to a low-rise, low-profile, frost-resistant fan device for tea plantations, which can be stored sideways in a room and has no obstacle to the use of the tea plant management device.

[0002]

2. Description of the Related Art Conventionally, a structure in which a frost prevention fan device is provided above a tea garden by using a building pole has recently become increasingly mechanized, so that a tea cutter, a pest control machine (insect control machine), and other tea garden management devices are used. Has been adopted. There is a problem that, when the tea mower or the like is moved or a tea mowing operation is performed, the column is obstructed (harmful) and the movement, the operation, and the like cannot be performed smoothly. In particular, in a situation where the building pillar is erected in a tea garden (field) such as a tea ridge, the harmful effects are large, and this is a problem to be improved. There is also one aspect that the building pole and the anti-frost fan device are not preferable in view of the landscape.

[0003] In view of the above situation, the present applicant has proposed several low-profile type tea garden frost prevention fan devices.
The outline is that a support is erected on a support buried in the tea garden, and a support is taken out from the support, a support is taken out from the support, an anti-frost fan is provided above the tea plant, and the anti-frost fan is driven to prevent frost,
Further, the support is immersed (inserted) in the support, and the anti-frost fan can be accommodated in the tea plant.

[0004] Although not a frost-proof fan device, there is a fan device for a golf course disclosed in Japanese Utility Model Laid-Open No. 5-83392 as a configuration for preventing an obstruction when the fan goes up and down or is not used.
This invention uses a four-stage type cylinder actuator mechanism to make a column provided with a fan at the upper end extend and contract, and expands the mechanism when in use and contracts when not in use. It is. Examples of the extendable structure include a cylinder actuator mechanism, a pantograph mechanism, a screw jack mechanism, and a link mechanism. Among them, there is a device related to the present invention in which the cylinder actuator shown in FIG.

[0005]

The structure proposed by the present applicant to provide a support on a support so as to be freely retractable is to use a frost prevention fan,
It has the feature that it can be stored in tea plants. However, it takes time and effort to raise and lower the pillars and the anti-frost fan, and in some cases, to assemble the components of the anti-frost fan, and because of its relatively heavy weight, it must have equipment or extra human means for lifting and lowering work And other issues are conceivable. This is a problem particularly in the tea garden industry where the number of elderly people is increasing or in a tea garden such as a slope.

[0006] Next, since the undulating construction in the invention of Japanese Utility Model Application Laid-Open No. 5-83392 employs a cylinder actuator, ancillary equipment such as piping is required, the structure becomes complicated, and the cost increases accordingly. Or a drive source for operating the cylinder is required, which complicates equipment and construction. There is also difficulty in installation due to land conditions such as sloping land and narrow land. In addition, under the above-mentioned land conditions, there are difficulties in installing and carrying in the equipment required for the construction, and the like, which is not suitable for the frost prevention fan device aimed at by the present invention. In addition, there is a problem that the structure becomes complicated and maintenance and handling of parts become complicated.

In this state, the fan is driven to blow air such as warm air into the tea garden in a substantially horizontal direction to lick the leaf surface of the tea plant. By blowing air in such a manner, the structure is such that a reliable frost prevention effect can be achieved. Of course, a swing operation in the horizontal direction and / or the multi-plane direction (different from the depression angle adjustment) may be added.

The state shown in FIG. 1 is shifted to the state shown in FIG.
That is, in order to accommodate the support in the tea plant, the tightening of the fixing means such as bolts and tightening tools is released, and the fixing of the support and the support is released, and then the support is turned over.
