Description

[Detailed description of the invention] This invention uses forced air from a fan to artificially reverse the temperature reversal phenomenon caused by radiant cooling in areas where there is a risk of frost damage, such as tea fields, mulberry fields, outdoor vegetable gardens, etc. This invention relates to a depression angle adjustment fitting for a pedestal used in a frost damage prevention device using a so-called fan that blows warm air from the upper layer onto the leaves of agricultural crops.

When installing this type of anti-frost fan on a slope, in order to achieve the same frost protection effect as on a flat site, it is desirable that the sloped ground and the mount described later be approximately parallel to each other. One of the devices is a fan depression angle adjustment device for varying the depression angle of a frost protection fan via a depression angle adjustment plate provided on a mount;
A so-called double depression angle adjustment device, which is equipped with a pedestal depression angle adjustment device that can adjust the mount to be approximately parallel to the sloped ground, has been put into practical use by the inventors of the present invention and has achieved some results. . However, since the pedestal depression angle adjustment device of this device is integrated with the pedestal, the pedestal can be fitted directly onto the pole of the anti-frost fan that is being used these days, without the need for any mounting tools. Anti-frost fan devices having a mounting cylinder on the bottom surface cannot be used, and the structure is complicated and costs are high.

Therefore, the object of the present invention is to provide a gantry depression angle adjustment fitting that is most suitable for a frost protection fan device having a mounting cylinder.

Hereinafter, one embodiment of the present invention will be specifically described based on the drawings.

Reference numeral 1 denotes, for example, a hollow cylindrical protruding body, into which a mounting cylinder 3 hanging vertically from a pedestal 2 is fitted. For example, a frost protection fan 4 and a fan motor 5, etc., whose depression angle can be changed, are installed on the pedestal 2, and these swingable frost protection fan devices capable of adjusting the depression angle are well known. Reference numeral 6 denotes a flat skirt-shaped attachment body provided at the lower end of the projecting cylinder 1, and fixing bolts 9, 1 are provided near the lower part of the sloped portions 7, 8 in the direction of expansion of the attachment body 6 (in the horizontal direction in the drawing).
0 are arranged to face each other. Furthermore, mounting body 6
The flat skirt-like shape may be one in which the slope portions 7 and 8 in the expansion direction are arcuate as shown in Fig. 3, or linear as shown in Fig. 4; Any flat skirt shape may be used as long as it has a shape. A support member 11 is provided on the inner surface of the part where the projecting cylinder 1 and the mounting body 6 are connected. The mounting body 6 is loosely fitted onto the upper end of the pole 12 of the anti-frost fan, and is fixed to the pole 12 straightly or at a predetermined inclination angle as described later using the fixing bolts 9, 10 and the support member 11. be stopped.

Next, to explain how the present invention is used, first screw both bolts 9 and 10 back to free the mounting body 6 relative to the pole 12, then tilt the mounting body 6 at a predetermined angle and then unscrew both bolts 9 and 10. Screw in each. As a result, the mounting body 6 is fixed at the above-mentioned inclination angle, and the protruding cylinder 1 is also tilted at a predetermined angle, and the pedestal 2 that is constructed via the protruding cylinder 1 is The anti-frost fan 4 is tilted so that it can correspond to the angle of the ground, for example, and the same anti-frost effect can be expected even on a slope as on a flat ground. When straightening the protruding cylinder 1, unscrew both bolts 9 and 10, and after straightening the mounting body 6, screw in both bolts 9 and 10. becomes straight, and the pedestal 2 also becomes horizontal with respect to the ground.

As described in detail above, the present invention has a flat cylindrical body that has a projecting cylinder into which a mounting cylinder vertically installed on a stand provided with a frost protection fan can be fitted, and a pair of fixing bolts provided on the projecting cylinder. It consists of a skirt-shaped mounting body,
Since this mounting body is configured to fit loosely into the upper end of the anti-frost fan pole, it is a gantry depression angle adjustment fitting suitable for a anti-frost fan device having a mounting cylinder, and can be mounted with one touch. In particular, since the mounting body is shaped like a flat skirt, its rocking and fixed state are maintained reliably, and it is durable and easy to handle. In addition, the structure is a simple window,
It is easy to manufacture and can be provided at low cost.
