Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pest-flight prevention device for preventing harmful birds from flying and covering vinyls for agriculture.
[0002]
[Prior art]
Conventionally, a hanging string is stretched around the field to prevent the arrival of harmful birds, and silver birds, CDs, Naruko or pseudo-tonboshi, crows, etc. that threaten birds visually and audibly are suspended on the hanging strings. Although there was something to prevent, there was nothing for exclusive use of the greenhouse.
[0003]
[Problems to be solved by the invention]
The vinyl stretched in an agricultural greenhouse was blown away by crows, tobi, white birch, etc., and it was difficult to take measures against it. In order to prevent such damage, there is a method of setting bamboo poles and wooden pillars around the house, but there is a problem that the cost is increased and the pillar breaks due to strong wind and breaks through the greenhouse. Most of the instruments for preventing harmful bird arrivals are exclusively for Tabata. The birds are hung from the strings that are reflected on the strings by the strings of 1m to 1.5m in height. There was nothing to stand on the roof of the house.
[0004]
[Means for Solving the Problems]
The present invention hangs a threatening object 4 threatening a harmful bird such as a belt-like silver paper or CD, a pseudo crow or a tobi on a hanging strap 2 which stands on a roof of a greenhouse 1 and is routed between the stands. It is intended to get rid of.
[0005]
The stand 3 is composed of a main body column 5 and three legs 6 branching from the column into a T-shape, and the legs 6 have a fixture 8 for holding the frame pipe 7 of the greenhouse from above the vinyl. Each of them is characterized by being swingably mounted.
[0006]
Further , the slide column 9 is inserted into the main column 5 of the stand 3 and the slide column 9 can be fixed to an arbitrary height with a set screw 10.
[0007]
Of the three legs (6a, 6b, 6c) branched into the T-shape of the stand 3, the central leg 6a is configured to be extendable and contractable in accordance with the pitch interval of the frame pipe 7 in the longitudinal direction of the greenhouse. The fixture of the center leg is fixed to the frame pipe, and the fixture 8 of the other leg (6b, 6c) is held and fixed to the frame pipe 7 in the lateral direction .

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram showing a state in which a pest flying prevention device of the present invention is attached to a roof of a greenhouse, FIG. 2 is a perspective view showing a state in which a stand of the pest flying prevention device is attached to a pipe of a house, and FIG. It is a perspective view of a stand.
[0009]
As shown in FIG. 1, the pest-flight prevention device of the present invention is a belt-like silver paper that stands up on a stand 3 that stretches a suspension string 2 at the front, center, and rear of the roof of a greenhouse 1, or Hang out threatening objects 4 that threaten birds, such as naruto, pseudo crows and tonbi, which make noises, and drive away harmful birds.
[0010]
As shown in FIG. 2, the stand 3 is composed of a main column 5 and three legs 6 branching in a T-shape from the base of the column. Fixtures 8 to be gripped from above are mounted so as to be swingable.
[0011]
Further, as shown in FIG. 3, the stand 3 is configured such that a slide column 9 is inserted into the main body column 5, and the stand can be fixed to an arbitrary height with a female screw 10. Of the three legs 6a, 6b, 6c that branch into a T-shape, the center leg 6a is telescopic and can be expanded or contracted according to the pitch interval of the frame pipe in the longitudinal direction of the greenhouse. The fixing tool 8 of 6c can be securely held by the pipe frame 7 extending in the lateral direction.
[0012]
【The invention's effect】
The present invention has the following effects.
1. By setting up a stand on the roof of the greenhouse, it is possible to easily install a hanging strap for preventing the arrival of harmful birds.
2. Since the central leg 6a of the stand can be extended and contracted, it can be aligned even if the interval pitch of the skeleton pipe of the house is different.
3. Since the stand for drawing the suspension strap is made to be extendable, the height of the suspension strap can be adjusted according to the shape and size of the suspension member.

Claims (1)

In the greenhouse for preventing harmful bird arrivals in the greenhouse, the intimidating object (4) threatening the harmful birds is suspended from the hanging string (2) which stands between the stands on the roof of the greenhouse (1). Of the three legs (6a, 6b, 6c) branching into a T-shape of the stand (3), the center leg (6a) is adjusted to the pitch interval of the frame pipe (7) in the longitudinal direction of the greenhouse. It is constructed so that it can be extended and contracted, and a fixture for the center leg is fixed to the frame pipe, and the fixture (8) of the other leg (6b, 6c) is held and fixed to the frame pipe (7) in the lateral direction. bird flying prevention device of vinyl house that was so.
