DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a veterinary repellent launcher for preventing crops and the like from being damaged by birds and animals.

[0002]

2. Description of the Related Art In order to prevent crops from being damaged by birds and beasts, various bird and animal repelling devices have been developed.
Or a method of repelling birds and beasts is being considered. For example, a bomber is one of them, which is set up in rice fields during the rice harvesting season, etc., and explodes at a certain time interval to expel the sparrow,
It prevents damage to paddy by sparrows. Capture devices such as traps for catching birds and animals approaching the field, and electric fences surrounding the field with energized wires are also a type of bird repellent device. Also, to prevent damage from birds,
They hang balloons with birds' eye-catching paintings on the fields, and wrap tapes that reflect light around the fields.

[0003]

The conventional bombers emit loud explosions at regular intervals and even if the crops are not actually damaged, so that human beings can hear noise. It is not preferable to use near a house. Also, there is a drawback that birds and beasts are not dangerous due to learning effects, and the repulsion effect diminishes as time passes. The use of balloons depicting eyeballs or tapes that reflect light also has the disadvantage that the repulsion effect is diminished by learning effects. Furthermore, even if a trapping device or the like is used, the effect of repelling birds and beasts cannot be expected so much, and it is not desirable from the viewpoint of coexistence of humans and birds and beasts or protection of birds and beasts. The conventional bird repelling device or repelling method is mainly for birds, and there is no effective repelling device or repelling method for animals such as monkeys, wild boars, and deer. The use of electric fences has a great effect on beasts,
There are disadvantages that the installation cost increases and a great deal of labor is required for maintenance.

The present invention has been made to solve the above-mentioned problems of the prior art, and the repelling effect is not weakened by the learning effect, and the damage caused by birds and animals while coexisting with humans and birds and animals. Can be effectively prevented,
Another object of the present invention is to provide a low cost and safe bird repellent launcher.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of a bird and animal repellent launcher according to the present invention will be described with reference to the drawings. In FIG. 1, one end (the left end in FIG. 1) of a case 1 having a substantially cylindrical shape as a whole has a bottom, the other end of the case 1 is open, and this open end is closed by a lid 5. . A pressure receiving plate 3 is attached to the center of the case 1 in the length direction, and the internal space of the case 1 is bisected in the length direction by the pressure receiving plate 3. In the space between the pressure receiving plate 3 and the lid 5 in the internal space of the case 1, a bird and animal repellent 4 is stored. The bird repellent 3 is mainly composed of chili powder.

The end of the case 1 on the side opposite to the opening end is squeezed to have a smaller diameter, and is located between the pressure receiving plate 3 and the bottom of the case 1 on the side opposite to the opening end. Explosive 2 is stored in the space. The gunpowder 2 may have the same specification as the gunpowder of a cracker used for a game at a party or the like, or may have a specification different from this. In any case, the gunpowder 2 has the string 9 and pulls the string 9 instantaneously. As a result, frictional heat is generated, and the explosive 2 ignites and explodes. The cord 9 extends outward from the bottom of the case 1. Two explosives 2 are used, and two strings 9 protruding from each explosive 2 toward the outside of the case 1 are bundled by a fastener 6 near the outer end thereof. The space between the pressure receiving plate 3 in which the explosive 2 is stored and the bottom of the case 1 is a space of an appropriate size so that the pressure when the explosive 2 explodes is effectively applied to the pressure receiving plate 3. Has become. The pressure receiving plate 3 is made of thick paper or the like so that the bird repellent 3 can be radiated from the opening end of the case 1 under the pressure of the explosive of the explosive 2. In addition, the lid 5 is used when the explosive 2 explodes.
It is made of a material that can be broken by the pressure applied through, such as thin paper. Note that case 1 in the example shown in FIG.
As described above, the diameter of the end opposite to the opening end is smaller and is stepped, and the opening end has a form in which a flange is integrally formed, A simple cylindrical shape having no steps or flanges as described above may be used.

Now, for example, holding the case 1 in one hand,
When the string 9 is momentarily pulled with the other hand, the explosive 2
Ignites and explodes. The pressure of this explosion is applied to the pressure receiving plate 3, and the pressure receiving plate 3 is pushed toward the open end of the case 1.
The pressure receiving plate 3 moves instantaneously toward the open end of the case 1 with the inner peripheral surface of the case 1 serving as a guide, and pushes out the bird repellent 3 toward the open end of the case 1. At this time, the pressure applied at this time causes the lid 5 to be torn, and the bird and animal repellent 3 is vigorously radiated from the opening end and scattered around. Therefore, if the bird / beast repellent 3 is fired at a bird or animal that is about to enter a field or an orchard, the explosion sound at the time of launching threatens the bird / beast, and the scattered bird / beast repellent 3 is exposed to the bird's eyes and nose. The pepper powder which adheres to the mucous membrane of the bird and forms the main body of the bird repellent 3 irritates the mucous membranes such as the eyes and nose of the bird and gives pain, and the bird does not endure the pain and escapes. Moreover, experimental results show that birds and animals that once experienced the stimulus of pepper powder are less accustomed to the above-mentioned stimuli, unlike conventional devices such as bombers, and do not approach the area from strong fear. It turned out that the bird and animal repelling effect was great. In addition, although the chili powder itself is strongly irritating, it is used only in foods and therefore has no toxicity.Therefore, it does not harm birds and beasts. Absent.

In the embodiment shown in FIG. 1, the case 1 has a substantially cylindrical shape, and at least a portion from the pressure receiving plate to the open end of the case has a cylindrical shape having the same diameter. Therefore, the pressure at the time of explosion of the explosive 2 is effectively transmitted to the pressure receiving plate 3 until the pressure receiving plate 3 reaches the opening end of the case, and the bird and animal repellent 3
Is effectively radiated, and the cylindrical portion of the same diameter of the case 1 functions as a guide, and the bird / beast repellent 3 is effectively radiated toward the target without being diffused unnecessarily.

FIG. 2 shows an example of the bird and animal repellent launcher according to the present invention in the course of development, and the case 21 has a conical shape. Gunpowder, pressure plate, bird repellent,
It has a lid, a string, and a fastener, and these members are denoted by the same reference numerals as those in the example of FIG. In FIG. 2, reference numeral 22 denotes a pipe seat. The example shown in FIG. 2 differs from the example shown in FIG. 1 in that the case 21 has a conical shape and the diameter increases toward the open end of the case 21 covered with the lid 5. Also in this example, the pressure receiving plate 3 receives a pressure due to the explosion of the explosive 2, the bird repellent 4 breaks the lid 5 and is radiated, and the bird repelling effect can be obtained. However, since the case 21 has a conical shape whose diameter increases toward its open end, the pressure is dispersed as the pressure receiving plate 3 is pushed out, and the bird repellent 4 is efficiently radiated toward the target. Could not. An improvement of this point is that substantially the entire case 1 is formed into a cylindrical shape as shown in FIG.

The veterinary repellent launcher according to the present invention can be loaded into the launching device to automatically launch the veterinary repellent only when necessary. FIG. 3 schematically shows the launching device. In FIG. 3, reference numeral 7 denotes a sensor, and 8 denotes a launching device main body. For example, one or a plurality of bird and animal repellent launchers as shown in FIG. 1 can be loaded in the launcher body 8. Sensor 7
Is composed of, for example, an infrared sensor and is installed facing a path for birds and animals to approach the field. Launcher body 8
Has a function of receiving the detection signal from the sensor 7 and instantaneously pulling the string 9 of the bird and animal repellent launcher. When a bird or animal enters the detection range of the sensor 7, the body temperature is
Is detected. In response to this detection signal, the string 9 of the bird repellent launcher is pulled in the launcher body 8, and the bird repellent is emitted from the bird repellent launcher.

FIGS. 4 and 5 schematically show an example of a mechanism for pulling the string 9 of the bird and animal repellent launcher provided in the launcher body 8. FIG. This example has a solenoid 10 as a drive source. The solenoid 10 has a plunger 11, and the plunger 11 is urged by a spring 12 in a direction protruding from the solenoid 10. The plunger 11 is connected to a horizontal portion of an L-shaped operation plate 13. A sleeve 15 is integrally mounted through a vertical portion of the operation plate 13, and the sleeve 15 is penetrated by a horizontally supported guide shaft 16. Therefore, the operation plate 13 and the plunger 11 can move along the guide shaft 16. A groove 14 is formed in the vertical portion of the operation plate 13 from the tip side. The upper end portion of the groove 14 is widened, and the string 9 of the bird repellent launcher is fitted in the groove 14, and the fastener 6 is hooked on the vertical portion of the operation plate 13. The solenoid 10 is excited by a detection signal from the sensor 7 described with reference to FIG. 3, for example.

In the state shown in FIG. 4, the plunger 11 and the operation plate 13 are projected from the solenoid 10 by the urging force of the spring 12 when the solenoid 10 is not excited. Now, for example, when the solenoid 10 is excited by a detection signal from the sensor 7, the plunger 11 is instantaneously attracted to the solenoid 10 against the urging force of the spring 12, and the operation plate 13 is instantaneously moved to the left in FIG. It is moved to. The movement of the operation plate 13 instantaneously pulls the string 9 of the bird repellent ejector, and as described above, the bird repellent mainly composed of pepper powder is emitted from the bird repellent ejector together with the explosion sound. The configuration inside the firing device main body shown in FIG. 4 is merely an example, and various types of firing devices can be considered.
