Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a device which is used by being attached to the entrance (nest) of a beehive, and more specifically, is formed so as to prevent damage caused by invasion of external enemies and nesting (branching) for breeding. The present invention relates to a nest mounting device for a beehive.

[0002]

[Prior art]

 Conventionally, a beekeeping nest box is usually provided with a plurality of nest boards that can be taken in and out one by one, and a slit-like nest is formed in the lower part of the front side plate.

[0003]

[Problems to be solved by the device]

 By the way, if a foreign enemy invades the beehive, the bees may be predated and the nest may be wiped out, or the bees may throw away the nest and escape. In this case, the bee's external enemies include birds, dragonflies, mantises, flying squirrels, frogs, spiders, and other bee companions. Among the bees of this external enemy are the Japanese honey bee (a subspecies of the honey bee), the honey bee (honey bee native to Europe and Africa), and the hornets such as the giant hornet (bear bee). There is a wasp. Especially in Japan, when the wasps become deficient in autumn, the wasps intensively attack the bees, and the damage is extremely large. Therefore, in beekeeping management, it is the most important issue to prevent the invasion of other bees that attack and prey on bees along with the disease of bees. Bees have a habit of nesting due to breeding. This bee is a phenomenon in which the nest box in which the old queen bee lived is transferred to the new queen bee and it goes out with the worker bee, but at the beekeeping site, the breeding state of the swarm is manipulated and this bee is intentionally suppressed. You may want to. However, the conventional nest box usually has a simple opening of the nest as described above, so it was not only easy to be seriously damaged by the invasion of external enemies in the past, but also to intentionally suppress the bees. I couldn't.

The present invention has been proposed in view of such conventional circumstances. Therefore, the technical problem of the present invention is that the working bees can freely move in and out, other bees having a larger physique than the working bees can prevent invasion, and the nest of a bee hive formed so as to intentionally suppress the split bees. It is to provide a mounting device.

[0005]

[Means for Solving the Problems]

 The present invention adopts the following technical means in order to solve the above problems. That is, the present invention comprises a plurality of bars 5 formed in a cover state covering the nest 2 of the nest 1 and having a front surface 4 facing the nest 2 arranged in parallel with each other at regular intervals D. The distance D is set so that the worker bees 12 in the nest box 1 can pass through but the bees 13 having a larger size than the worker bees 12 cannot pass through.

In this case, the bee 13 having a larger physique than the worker bee 12 means another kind of bee that is a foreign enemy of the worker bee 12, and a queen bee. In addition, the width of the bee 13 in the nest box 1 that can pass through, but the bee 13 having a larger body than the worker bee 12 does not pass is the width that can prevent the invasion of other bees that attack the worker bee 12 and prey on it, and It means the width that can prevent the queen bee from leaving.

[0007] Specifically, when the worker bee 12 is a Japanese honey bee, the external enemy is, for example, a hornet such as a honey bee or a giant hornet, and when the worker bee 12 is a honey bee, there is a hornet such as a hornet. In this case, honeybees have the advantages of being easier to manage and producing more honey than Japanese honeybees, and since the mainstream of beekeeping today is honeybees, the above interval D is usually a foreign enemy of honeybees. It is preferable to select a width that can prevent a certain hornet from entering the nest box 1.

Further, in the present invention, it is preferable that the lowermost bar 5a is formed to be vertically movable so that, for example, a queen bee can temporarily enter and leave. In this case, specifically, it can be achieved by forming the hole 10 through which the left and right ends of the lowermost bar 5a pass through to have a large diameter so that the bar 5a is vertically displaced and fixed.

Since the birdhouse 1 is used outdoors, the present invention is made of, for example, stainless steel, aluminum alloy, or a metal whose surface is rust-proofed so as to have good weather resistance and durability. It is preferable to use a corrosion-resistant metal material such as a material.

[0010]

[Embodiment of device]

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The attaching device of the present invention is formed in a cover state for covering the nest 2 of the nest box 1. The nest box 1 is formed, for example, in a size of about 50 cubic centimeters, and is provided with ten plate-like nest boards 3 which are formed so as to be freely taken out in parallel. The attachment of the present invention is entirely made of, for example, stainless steel so as to have weather resistance and durability.

The front surface 4 facing the nest 2 is partitioned by a plurality of bars 5 which are horizontally arranged in parallel with each other at a constant interval D. As shown in FIG. 2 and the like, the bar 5 has its left and right ends fixed to a pair of left and right side plates 6, 6. Reference numeral 7 is a mounting plate which is continuous with the side plate 6 and extends laterally, and 8 (see FIGS. 3 and 4) is a screw hole opened in the mounting plate 7. In the mounting device of the present invention, a set screw 9 (see FIGS. 2 and 4) is screwed into the screw hole 8 and mounted on the nest box 1 so as to cover the nest 2.

Further, in this embodiment, the lowermost bar 5a is loosely inserted into the hole 10 (see FIGS. 1 and 5B) whose left and right ends are opened in the side plate 6, and the margin of the diameter of the hole 10 is used. It is formed so that it can be vertically displaced. Reference numeral 11 is a nut screwed to the left and right ends of the lowermost bar 5a.

The interval D is set so that the worker bees 12 in the nest box 1 can pass through but the bees 13 having a larger body than the worker bees 12 cannot pass through. This interval D is appropriately selected according to the type of bee.

That is, the Japanese honeybee, which is a subspecies of the honeybee, which is a subspecies of the Japanese honeybee, is usually about 12 mm in length and about 4 mm in abdominal thickness. On the other hand, for example, the honeybee has a body length of about 15 mm and the abdominal thickness is about 5 mm, and the hornet is more than twice as large as the honeybee, with a body length of about 30 mm and a female length of about 40 mm. is there. Therefore, when the worker bee 12 is a Japanese honey bee, it is preferable that the distance D is selected to be about 4 mm, which allows the Japanese honey bee to come in and out. Further, when the worker bees 12 bred in the nest box 1 are honeybees, it is preferable to select the interval D of about 5 mm so as to prevent the invasion of the hornets that attack and prey on the honeybees.

Next, the operation of the present invention will be described. The present invention is used by attaching to the nest box 1 so as to cover the nest opening 2 of the nest box 1. Since the front surface 4 is partitioned by the bar 5 with a space D, the worker bees 12 in the nest box 1 can enter and exit from between the bars 5, and the bees 13 having a larger physique than the worker bees 12 are prevented from entering and exiting.

[Effect of device]

 INDUSTRIAL APPLICABILITY As described above, the present invention comprises a plurality of bars that are formed in a cover state that covers the nest of a nest box, and the front surface facing the nest is arranged in parallel with each other with a certain distance between them. However, the worker bees in the birdhouse are allowed to pass, but the bees larger than this worker bee are not passed. Therefore, according to the present invention, it is possible to prevent the attack of other types of bees that are foreign enemies without restricting the behavior of the worker bees in the nest box. It prevents the bees from throwing away the birdhouse and escaping. Further, according to the present invention, it is possible to prevent the queen bee from coming out of the birdhouse, so that it is possible to intentionally suppress the branch bee that works together with the queen bee.

When the lowermost bar is formed so as to be vertically movable as described in claim 2, the position of the lowermost bar is changed so that, for example, a queen bee can move in and out, the interval between other bars is set. It is possible to make it larger. Therefore, according to this, there is an advantage that the usability is improved because the queen bees can be released to the mating and the bees can be separated without removing the mounting device of the present invention from the nest.

Further, as described in claim 3, when the entirety is formed of a corrosion-resistant metal material, weather resistance and durability can be improved.
