Abstract

PROBLEM TO BE SOLVED: To provide the subject apparatus, comprising a specific constitution for turning a rotating rod attached to the top of a rotating tower parallel to the ground surface, capable of smoothly rotating, producible at a low cost and readily installing and removing the rod. SOLUTION: This rotating tower for scaring fowls is obtained by providing supporting pins to be supporting fulcra of rods 33 at the tips of arms 32 overhung from a rotating plate 31 at the top of the rotating tower, engaging the supporting pins with recessed parts formed near the roots of the rods 33, thereby attaching the rods 33 to the rotating plate 31 and composing the rotating rod 30. Furthermore, the rotating rod 30 is connected through a wire rope passed through the interior of a tower column 20 to a driving device 10 to absorb the resistance due to a natural wind and smoothly rotate the rotating rod 30. On the other hand, the roots of hooked rods 36 having forked tips are rotatably supported with the pins attached near the roots of the arms 32 and the tips of the roots of the rods 33 are supported by the fork of the hooked rods 36 to readily install and remove the rods 33 from the rotating plate 31 by operating the hooked rods. Bowllike wind receivers 38 are fixed to the rotating plate 31 or arms 32 to prevent the rotating rod 30 from reversibly rotating.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing damage to wild birds in fish farms, farms, orchards and the like.

[0002]

2. Description of the Related Art As a device for repelling wild birds to prevent feeding damage, there are a blaster, a bird net, a tension string, ultrasonic waves, a reflection tape, and a scoop.

[0003]

[Problems to be Solved by the Invention] A method of repulsing or repelling wild birds by rotating or swinging on a tree with a height of several M above the ground, and in a strong wind the rotated or swung object can be easily removed and reattached. It is a simple one, one that can function against normal natural winds, and one that inclines and rotates a threatening object according to the height of trees or the inclination of the ground, and there is no inexpensive equipment at present. Is.

[0004]

In the bird chasing rotary tower of the present invention, a plurality of rods are attached to an arm portion of a rotary plate provided on the top of a tower pillar standing on a driving device to rotate as a rotary rod.

A deceleration motor is adopted as a driving device, and a rotating plate is connected to the rotating plate through a wire rope that passes through the inside of the tower, and the bent portion is a mechanism that is transmitted by passing through a gently curved pipe.

[0006] The rod meshes with a pin at the tip of the arm protruding from the rotating plate, and a recess provided near the base of the rod is meshed with the rod, and the outermost end of the rod base is rotatably supported by the arm by a pin. It has a bifurcated shape with a bifurcated key bar that supports it to form a rotating rod.

A bowl-shaped wind receiver is provided on the rotary plate or the arm to fix it.

[0008]

[Operation] The wire rope as a transmission shaft also plays the role of a cushioning material and absorbs the resistance due to natural wind. Even if the shaft of the drive motor is mounted at a right angle to the tower pillar, the 90 ° bent portion of the wire rope is gently bent. It can be manufactured at low cost because it rotates smoothly by passing through a pipe and does not require a mechanism such as a bevel gear, worm & wheel gear, or universal joint.

Even when the rotary rod is tilted and turned, only the tower columns need to be bent, and no special transmission mechanism such as a universal joint or a flexible joint is required.

By pulling a string attached to the lower end of the rod in the direction of the tip of the rod, the rod is disengaged from the base of the rod and can be easily removed from the rotating plate. Hold the intermediate part and engage the support pin at the end of the arm with the recessed part of the base of the rod and pull the lower end of the key rod to the center of the rotating tower, the forked part of the key rod will engage and support the rod,
The rod is fixed to the arm of the rotating plate.

[0011] Further, the string attached to the lower end of the key rod is wound around the tower pillar and bound by a ring-shaped weight that moves freely, whereby the key rod and the rod are more firmly fixed.

The bowl-shaped wind receiver attached to the rotary plate or the arm is attached in the direction of rotation of the rotary blades to prevent the rotary rod from becoming a windmill by natural wind and to prevent reverse rotation of the rotary rod and the reduction motor.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. FIG.

The lower drive unit (10) houses a reduction motor (11) and is fixedly installed on the ground (see FIG. 3).

Tower column (20) standing on the drive unit (10)
The rotating rod (30) at the top is rotated through the wire rope (21) that passes through the inside (see FIGS. 2 and 3).

FIG. 2 shows the top of the tower (20) and the rotary rod (3
0) represents the relation and mechanism, and the wire rope (21) in the tower column (20) has a ring-shaped eyebolt (23) attached to the rotating shaft (28) integrally attached to the rotating plate (31) with the bolt (39). ) Is tied with a wire clamp (22).

Further, the wire rope (21) and the eyebolt (23) can be tied by pulling it out from the tower pillar (20) and separating it.

In FIG. 3, inside the drive unit (10), the wire rope (21) that has passed through the inside of the tower column (20) curves through the curved pipe (14) and passes through the joint (12). Connected to the deceleration motor (11).

FIG. 4 shows the upper surface of the rotary rod (30) and FIG. 5 shows the side surface of the rotary rod (30). The rotary rod (30) is fixedly integrated with the rotary shaft (28) in the top of the column (20) by bolts (39). And a recess (37) attached to a rod (33) is engaged with a support pin (34) provided at the tip of an arm (32) extending two in four directions from a rotating plate (31), and placed.

At the end of the base of the rod (33), the arm (3
2) The pin (34) provided at the base is pivotally supported to engage and support the forked part of the tip of the key rod (36).

The rotating rod (3) is provided by the rotating plate (31) or four bowl-shaped wind receivers (38) attached to the arm (32).
Make 0) a windmill.

FIG. 6 shows a rotary tower in which a tower pole (20) is bent to rotate the rotary rod (30) by tilting it on a sloping ground, and FIG. 7 shows a cross section of a bent portion of the tower pillar (20). There is.

[0023]

EFFECT OF THE INVENTION Since the rotary rod is supported only by the support pin and the key rod at the arm portion, the rod can be easily attached and detached.

By using the wire rope to transmit the rotational movement, mechanical elements such as a bevel gear, a worm & wheel gear, a universal joint, etc. are not required even in the axial change in the driving device or the bent portion of the tower.

The rotating plate or the bowl-shaped wind receiver attached to the arm acts as a windmill by natural wind and rotates only in a fixed direction, so that the rotating rod is prevented from rotating in the reverse direction.

Since the tower pole can be bent to incline the rotary rod, the rotary rod can be rotated according to the height even on a sloping ground even if the ground surface is parallel or the height of trees is high or low.
