Description

Technical Field

[0001] The present invention relates to the technical field of breeding devices, and particularly to a bumblebee breeding device. Background Art

[0002] Bumblebees are a type of polyphagous social insects. Because bumblebees are resistant to low temperatures and have strong foraging abilities, especially with the characteristic of buzz pollination, bumblebees are also known as the "pollination masters" of greenhouse crops. With the breakthrough of bumblebee artificial breeding technology, bumblebees are now widely used for pollinating greenhouse crops worldwide. Currently, many countries are researching and breeding pollinating bumblebees. Cultivating queens with a large number and good quality is the key technology for breeding pollinating bumblebees. Therefore, when breeding bumblebees, it is usually necessary to use a breeding box for breeding.

[0003] However, the existing bumblebee breeding devices are generally in a sealed state during use. And bumblebee feces will produce a large number of bacteria when in a sealed state for a long time. Moreover, the existing bumblebee breeding devices are generally integrated, which is not convenient to check the internal situation. At the same time, heat dissipation is also a problem. Therefore, we make improvements and propose a bumblebee breeding device. Summary of the Invention

[0018] The present invention provides a bumblebee breeding device. It has the following beneficial effects:

[0019] First, by placing one end of the main bumblebee nest inside the quick connection mechanism, the quick connection mechanism can clamp the surface of the main bumblebee nest for quick installation.

[0020] After placing the main bumblebee nest inside the quick connection mechanism arranged inside the bumblebee breeding box, start the servo motor at this time. The servo motor will drive the second connection disk to rotate in cooperation with the first connection disk and the transmission belt. The positive and negative threaded rod installed at the center on one side will also rotate accordingly. At this time, the positive and negative threads of the positive and negative threaded rod will drive an elliptical movable block to move respectively. The semi-circular limiting block fixedly connected to one end of the elliptical movable block through a fixed connecting rod will gradually tighten inward, thus clamping tightly on the outer surface of the main bumblebee nest;

[0021] The telescopic rod and the buffer spring arranged on the semi-circular limiting block can provide a certain buffering effect to prevent damage to the main bumblebee nest due to excessive clamping force. Moreover, the suction cup installed at one end of the telescopic rod can adsorb on the main bumblebee nest to prevent sliding;

[0022] When the device is used for a long time, start the biaxial motor in the ventilation mechanism at this time. The start of the biaxial motor will drive the ventilation fan blades to rotate at both output ends. At this time, the air circulation is driven, and the activated carbon filter block can filter harmful substances, increasing the practicality of the device;

[0023] The heat dissipation mechanism provided on one side of the bumblebee breeding box can rotate the knob according to the situation during use. At this time, the knob will drive a number of first movable disks to rotate in cooperation with the second movable disk and the linkage belt, and the louvers provided on one side of the first movable disk will gradually open to facilitate heat dissipation.

[0047] As Figures 1 to 8 shown, the quick connection mechanism 5 includes a device housing 501 and an elliptical fixing plate 506;

[0048] The device housing 501 is fixedly installed on one side inside the bumblebee breeding box 1. On both sides at one end inside the device housing 501, an oval fixing plate 506 is fixedly installed. An anti - reverse threaded rod 504 is movably installed between the two oval fixing plates 506.

One end of each telescopic rod 511 away from the semi - circular limiting block 509 is provided with a suction cup 513. The suction cup 513 is movably clamped on the outer surface of the bumblebee main nest 4. After placing the bumblebee main nest 4 inside the quick - connection mechanism 5 arranged inside the bumblebee breeding box 1, start the servo motor 505 at this time. At this time, the servo motor 505 will drive the second connecting disc 510 to rotate in cooperation with the first connecting disc 508 and the transmission belt 507. The anti - reverse threaded rod 504 installed at the center of one side will also rotate together. At this time, the positive - threaded and reverse - threaded parts of the anti - reverse threaded rod 504 will drive an oval moving block 502 to move respectively. The semi - circular limiting block 509 fixedly connected by the fixed connecting rod 503 at one end of the oval moving block 502 will gradually tighten inward, thus clamping on the outer surface of the bumblebee main nest 4;

[0049] The telescopic rods 511 and buffer springs 512 provided on the semi - circular limiting block 509 can provide a certain buffering effect, preventing damage to the bumblebee main nest 4 due to excessive clamping force. And the suction cup 513 installed at one end of the telescopic rod 511 can adsorb on the bumblebee main nest 4 to prevent sliding.

[0050] As Figures 1 to 8 shown, the ventilation and air - change mechanism includes a protective housing 801 and a through - hole 802;

[0051] The protective housing 801 is fixedly installed inside the bumblebee main nest 4. A plurality of through holes 802 are formed at one end of the protective housing 801. An activated carbon filter block 806 and a biaxial motor 807 are fixedly installed inside the protective housing 801 through connecting rods. Both output shafts of the biaxial motor 807 pass through an activated carbon filter block 806 movably, and a plurality of replacement fan blades 805 are arranged on the output shafts. An air inlet 803 is arranged at one end of the protective housing 801, and an air outlet 804 is arranged at the other end of the protective housing 801. Protective nets are arranged at both the air inlet 803 and the air outlet 804. When the device is used for a long time, the biaxial motor 807 in the ventilation and air change mechanism 8 is started at this time. When the biaxial motor 807 is started, both output ends will drive the replacement fan blades 805 to rotate, driving the flow of air at this time, and the activated carbon filter block 806 can filter harmful substances, increasing the practicability of the device.

[0052] Working principle:

[0053] First, one end of the bumblebee main nest 4 is placed inside the quick connection mechanism 5. At this time, the quick connection mechanism 5 can clamp the surface of the bumblebee main nest 4 for quick installation. At the same time, it can be taken out separately when it is necessary to check the internal situation. Moreover, the heat dissipation mechanism 3 arranged on one side of the bumblebee breeding box body 1 can be opened according to requirements to adjust the temperature inside the bumblebee breeding box body 1. The ventilation and air change mechanism 8 arranged inside the bumblebee main nest 4 can adjust the internal ventilation environment according to requirements, and the feces receiving plate 10 that can be taken out movably is convenient for cleaning;

[0054] After the bumblebee main nest 4 is placed inside the quick connection mechanism 5 arranged inside the bumblebee breeding box body 1, the servo motor 505 is started at this time. At this time, the servo motor 505 will drive the second connection disk 510 to rotate in cooperation with the first connection disk 508 and the transmission belt 507. The positive and reverse threaded rod 504 installed at the center on one side will also rotate together. At this time, the positive thread and the reverse thread of the positive and reverse threaded rod 504 will drive an oval movable block 502 to move respectively. The semi-circular limit block 509 fixedly connected to one end of the oval movable block 502 by a fixed connecting rod 503 will gradually tighten inward, thus clamping on the outer surface of the bumblebee main nest 4;

[0055] The telescopic rod 511 and the buffer spring 512 arranged on the semi-circular limit block 509 can provide a certain buffer effect to prevent damage to the bumblebee main nest 4 due to excessive clamping force. Moreover, the suction cup 513 installed at one end of the telescopic rod 511 can adsorb on the bumblebee main nest 4 to prevent sliding;

[0056] When the device is used for a long time, the biaxial motor 807 in the ventilation and air exchange mechanism 8 is started at this time. When the biaxial motor 807 is started, both output ends will drive the replacement fan blades 805 to rotate, driving the circulation of air at this time, and the activated carbon filter block 806 can filter harmful substances, increasing the practicality of the device;

[0057] The heat dissipation mechanism 3 provided on one side of the bumblebee breeding box body 1 can rotate the knob 301 according to the situation during use. At this time, the knob 301 will cooperate with the second movable disc 304 and the linkage belt 303 to drive a plurality of first movable discs 302 to rotate, and the louvers 305 provided on one side of the first movable disc 302 will gradually open, facilitating heat dissipation.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
