Description

Technical Field

[0001] This application belongs to the field of biological control, and more specifically, relates to a box with a structure for killing bee mites. Background Technology

[0002] Bees are social insects that live in colonies. Major mites, such as Varroa destructor and Tropicalaspeps mites, are considered to be one of the factors that threaten beekeeping. They are mostly found in the young bees (including drones and worker bees) in the hive and appear together with the young bees, repeating their cycle.

[0003] To control bee mites, refer to the patent document published in Chinese Patent Publication No. CN1484488A, which discloses a method and device for controlling mites in a beehive, and specifically discloses the following technical solution: The beehive includes:

[0004] (a) A support member provides a base for constructing cells (honeycombs) on at least one of its surfaces so that worker bees can build the honeycomb and the queen bee can lay drone eggs in the cells, from which the eggs in the honeycomb cells will later develop into drone larvae and pupae; and (b) an electric heating device adjacent to or within the support member enables selective treatment of drone larvae and pupae and mites on drone larvae and pupae, thereby killing the mites. It also relates to a honeycomb for supporting drone larvae and pupae within a hive, the honeycomb comprising: (a) a frame defining the boundaries of the honeycomb and providing a foundation for the installation of the honeycomb within the hive; (b) a support member mounted within the frame, capable of providing a foundation for constructing honeycomb cells on at least one of its surfaces so that worker bees can make cells and the queen bee can lay drone eggs in the cells, from which the eggs in the honeycomb cells grow into drone larvae and pupae; and (c) an electrothermal element mounted across the support member, wherein the element is electrically connected to a power source to directly heat the drone larvae and pupae to kill mites on the drone larvae and pupae.

[0005] However, the aforementioned structure uses electric heating, selectively and directly applying electricity to a separate honeycomb containing drone larvae and pupae to kill mites. This method is quite difficult and not well-suited for beekeeping. Secondly, using insecticide powder to kill mites is a common method. To avoid mites developing resistance from prolonged use of insecticide powder, various insecticide powders can be used alternately. Improving the distribution efficiency of insecticide powder within the hive and enhancing mite control effectiveness has become a key technical challenge for the industry. Summary of the Invention

[0024] The technical solutions described in this application will be explained and illustrated below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] like Figures 1 to 6 As shown, a bee mite-killing box includes a box body 1, which is rectangular with an open top and a sealed bottom, forming an internal space to accommodate a nest frame 27. The box body 1 has a threaded hole at the top opening, and is connected to a cover connecting part 3 via the threaded hole and fasteners. The cover connecting part 3 and the cover body 2 are integrally formed, and the cover body 2 and the box body 1 together constitute the chamber for bees to build their nest. An internal filter 29 is also installed in the space formed by the box body 1 and the cover body 2 within the cover connecting part 3. The internal filter 29 separates the space inside the cover body 2 from the space inside the box body 1, preventing bees from entering the interior of the cover body 2 and interfering with other equipment.

[0027] The box 1 has a box inlet 19 on one side of its bottom end, and the cover 2 has an upper outer box 33 integrally formed on its top. The top of the upper outer box 33 has a box top plate 10, and the box top plate 10 has an integrally formed box exhaust plate 11 with several through holes. The box inlet 19, the box exhaust plate 11, and the upper outer box 33 work together to realize the flow of external air into the box and the exhaust channel of gas inside the box to the outside, so as to facilitate air circulation and ensure the normal nest building and growth of bees.

[0028] The box 1 has several mite removal holes 26 on two sides perpendicular to the nest frame 27. The mite removal holes 26 on the two side walls of the box 1 are located in the upper and lower areas of the side walls, respectively.

[0029] The housing 1 includes a lower outer housing 23 and an inner housing 24. A side wall chamber 32 is formed between the lower outer housing 23 and the inner housing 24. The side wall chamber 32 forms an upper chamber and a lower chamber through a cavity partition 25. The cavity partition 25 is fixedly connected to the lower outer housing 23 and the inner housing 24 respectively.

[0030] The side wall chamber 32 is provided with several pipes in the upper chamber and lower chamber respectively, which are connected to the side wall mite removal holes 26 arranged in rows or columns. These pipes are also connected to the air collection boxes 18 in the upper chamber and lower chamber respectively. The air collection boxes 18 in the chamber are connected to one end of the distribution cylinder air outlet pipe 14 arranged externally through the rear branch pipe 16. The other end of the distribution cylinder air outlet pipe 14 is connected to several distribution cylinders 5 respectively.

[0031] The distribution cylinder 5 is fixedly connected to the side of the cover 2 via the distribution cylinder base 4. The distribution cylinder outlet pipe 14 is connected to the bottom end of the distribution cylinder 5. The distribution cylinder 5 has an inlet pipe 6 connected to its side wall near the middle position. A push rod piston 13 is provided inside the distribution cylinder 5. When the push rod piston 13 moves relative to the distribution cylinder 5 inside the distribution cylinder 5, it can send the gas delivered by the distribution cylinder inlet pipe 6 through the distribution cylinder outlet pipe 14 to the rear branch pipe 16.

[0032] The push rod piston 13 is driven by the push rod 12, which can be an electric push rod or a linear motor. The push rod 12 is fixed to the frame on both sides of the upper outer box 33. A medicine placement box 7 is integrally installed on the upper part of the frame, and the distribution cylinder air inlet pipe 6 is connected to the medicine placement box 7. The medicine placement box 7 also has a placement box air inlet pipe 8 connected to the upper outer box 33.

[0033] Example 2

[0034] See also Figures 1 to 6 A box with a bee mite killing structure is disclosed, wherein the distribution cylinder air outlet pipe 14 is also connected to the front air collection box 17 through the front branch pipe 15. The front air collection box 17 is located at the box body 1 on both sides of the box body inlet 19, and the front air collection box 17 is also connected to the box body inlet 19 through the inlet connecting pipe 21. The box body inlet 19 has a hollow rectangular shell extending away from the box body 1, and a plurality of inlet exhaust holes 20 are respectively provided on the inner side of the top and bottom of the box body inlet 19.

[0035] The structure and connection relationships of the remaining parts are the same as those described in Example 1, and will not be repeated here to avoid unnecessary details.

[0036] Example 3

[0037] See also Figures 1 to 6 A box with a bee mite killing structure, wherein a one-way valve is provided at the connection position between the air outlet pipe 14 of the distribution cylinder and the distribution cylinder 5, and a one-way valve is provided at the connection position between the air inlet pipe 6 of the distribution cylinder and the distribution cylinder 5. The one-way valves at these two positions have opposite opening and closing states, that is, when one one-way valve is in the open state, the other one-way valve is in the closed state.

[0038] The upper outer casing 33 is provided with an air exchange filter cylinder 30 inside, and an air exchange fan body 31 is provided inside the air exchange filter cylinder 30. The opening of the air exchange filter cylinder 30 at the top of the air exchange fan body 31 is connected to the exhaust plate 11 of the casing as a whole.

[0039] A plurality of top filter cylinders 9 are integrally provided at the top plate 10 of the box body around the exhaust plate 11. The bottom end of the top filter cylinder 9 is open and communicates with the inside of the cover 2. The inside of the top filter cylinder 9 is filled with filter core. The top end of the top filter cylinder 9 is sealed and communicates with the air inlet pipe 8 of the placement box at the corresponding position.

[0040] The housing 1 has a nest frame limiting block 28 within the space formed by the inner housing 24. The nest frame limiting block 28 has a limiting groove for placing nest frames 27. A gap is formed between adjacent nest frames 27 to allow airflow through the mite removal holes 26 on the side walls. The nest frame limiting block 28 also allows for gaps between the nest frames 27 and the internal filters 29 installed on the circumferential side walls, bottom, and top of the inner housing 24 to ensure airflow.

[0041] The structure and connection relationships of the remaining parts are the same as those described in Embodiment 1 or Embodiment 2, and will not be repeated here to avoid tedious writing.

[0042] Based on the above embodiments, this application will continue to describe and illustrate the technical features and working process involved therein with reference to the accompanying drawings, so as to help those skilled in the art to fully understand the technical solution of this application and be able to reproduce it.

[0043] In this application, the box 1 is used to place the frames 27, which serve as the foundation for bees to build their honeycomb. A frame retaining block 28 needs to be provided at the connection point between the frame 27 and the box 1. The frame retaining block 28 should have a certain thickness and be able to be machined with placement grooves corresponding to the frames 27. The placement grooves are distributed along the length of the frame retaining block 28, and the presence of the placement grooves ensures sufficient airflow gaps and space for bee movement between adjacent frames 27.

[0044] In this application, a plurality of side wall mite removal holes 26 are processed on the inner wall of the box 1, which is perpendicular to the nest frame 27, and are distributed in a matrix. The side wall mite removal holes 26 on both sides of the nest frame 27 are located at the upper and lower parts of the inner wall of the box 1, respectively. This arrangement allows air containing mite removal agent to flow into the box 1 from the upper side wall mite removal holes 26 and out from the lower side wall mite removal holes 26 in the first cycle; in the second cycle, it flows in from the lower side wall mite removal holes 26 and out from the upper side wall mite removal holes 26.

[0045] In this application, the side wall mite removal holes 26 are respectively connected to corresponding pipes. These pipes refer to rows or columns of side wall mite removal holes 26 being connected to corresponding air collection boxes 18 inside the box via pipes. The air collection boxes 18 inside the box are respectively located in the upper and lower chambers at corresponding positions. The upper and lower chambers are formed within the side wall chambers 32 by cavity partitions 25. The side wall chambers 32 are formed by a lower outer box 23 and an inner box 24, which are connected to form a complete box 1 by cavity partitions 25.

[0046] The air collection box 18 inside the box can hold mite-removing agents, which are released under the action of air input by the rear branch pipe 16 and flow out through the corresponding mite-removing hole 26 on the side wall via the pipeline.

[0047] The rear branch pipe 16 serves as a branch pipe of the distribution cylinder outlet pipe 14. The top end of the distribution cylinder outlet pipe 14 has multiple connectors, each of which is connected to a corresponding distribution cylinder 5. The distribution cylinder 5 is fixed to the side wall of the cover 2 via the distribution cylinder seat 4. Inside the distribution cylinder 5, there is a push rod piston 13 that moves relative to it. When the push rod piston 13 reciprocates inside the distribution cylinder 5, it can send the gas supplied by the distribution cylinder inlet pipe 6 into the distribution cylinder outlet pipe 14, and it can also send the gas in the distribution cylinder outlet pipe 14 into the distribution cylinder inlet pipe 6, thus realizing the first cycle and the second cycle.

[0048] Based on the above description, one-way valves with opposite opening states are required at the connection points of the distribution cylinder inlet pipe 6 and the distribution cylinder 5, and at the connection points of the distribution cylinder outlet pipe 14 and the distribution cylinder 5, to ensure the smooth operation of the first and second cycles. In this application, the distribution cylinder inlet pipe 6 is connected to the agent placement box 7, which also includes a placement box inlet pipe 8. The placement box inlet pipe 8 is connected to the internal chamber of the cover 2 through the top filter cylinder 9. This structure ensures airflow within the cover 2 and solves the problem of gas source within the agent placement box 7. Furthermore, it reduces the supply of mite-killing agent as the number of cycles increases.

[0049] In this application, the cover 2 is integrally provided with an upper outer casing 33 at its top. The bottom end of the upper outer casing 33 communicates with the internal cavity of the cover 2. An exhaust plate 11 with several through holes is integrally provided at the top opening of the upper outer casing 33. The interior of the upper outer casing 33 is connected to the ventilation filter cylinder 30 via a frame. The bottom end of the ventilation filter cylinder 30 is sealed, and the top end is sealed by the exhaust plate 11. The ventilation filter cylinder 30 includes a filter outer shell and a filter inner shell. The filter inner shell and the filter outer shell are respectively machined with several filter holes on their circumferential sidewalls. Sufficient gaps are left between the filter inner shell and the filter outer shell to fill the filter core. The gas inside the cover 2 enters the interior of the ventilation filter cylinder 30 through the filter outer shell, filter core, and filter inner shell, and is discharged through the exhaust plate 11 by the ventilation fan 31 inside the ventilation filter cylinder 30. The function of this structure is to facilitate the flow of gas from the inlet 19 of the box into the interior of the cover 2, and to send the gas inside the cover 2 out through the air exchange filter 30 and the air exchange fan 31, thereby realizing the flow of internal airflow, improving fluidity, and facilitating the diffusion of the mite-removing agent delivered through the mite removal hole 26 on the side wall within the box 1, thereby improving the degree of diffusion.

[0050] In this application, the top filter cylinder 9 also needs to be filled with a filter core. The function of the filter core is to filter the air inside the cover 2 to avoid affecting the medicine in the medicine placement box 7 and the medicine in the gas collection box 18 inside the box, thereby improving the usability of the medicine. The top filter cylinder 9 is distributed on the top plate 10 of the box around the exhaust plate 11 of the box, and it corresponds to the air inlet pipe 8 of the placement box at the same location.

[0051] In this application, a shock-absorbing structure, such as a shock-absorbing pad, may be provided at the connection point between the cover connecting part 3 and the top end face of the box 1 to avoid the impact of the working device on the top of the cover 2 on the bee colony inside the box 1. Therefore, see [reference needed]. Figures 1 to 5 The structure shown has grooves on the top end face of the housing 1 and the bottom end face of the cover connecting part 3, which are large enough to accommodate shock-absorbing pads. In addition to the above locations, shock-absorbing pads also need to be distributed on the connecting end faces of the housing 1 and the cover connecting part 3.

[0052] In this application, in addition to forming an entrance at the bottom of one side of the box 1, the box entrance 19 also needs to extend a certain distance away from the box 1 to ensure that there are enough inlet vent holes 20 distributed on the top inner wall and bottom surface of the box entrance 19. This allows the mite-removing agent delivered by the front branch pipe 15 to be sprayed into the box entrance 19 through the inlet vent holes 20, thereby achieving mite removal for bees entering and exiting through the box entrance 19.

[0053] The front branch pipe 15 can be connected to the front gas collection box 17 on both sides. The front branch pipe 15 is connected to the gas outlet pipe 14 of the distribution cylinder. It is also under the control of the distribution cylinder 5. During the relative movement of the push rod piston 13 and the distribution cylinder 5, the first cycle and the second cycle can be alternated.

[0054] The distribution cylinders 5 connected to both sides of the cover 2 operate in opposite directions. That is, when the distribution cylinder 5 and push rod piston 13 on one side of the cover 2 are pushed in the direction of the distribution cylinder outlet pipe 14, the distribution cylinder 5 and push rod piston 13 on the other side move away from the distribution cylinder outlet pipe 14.

[0055] At the entrance of the box entrance 19, a baffle is hinged. The top of the baffle is hinged to the top of the box entrance 19, and there is a sufficient gap for movement between the bottom of the baffle and the bottom end face of the box entrance 19. When the bee moves into the box entrance 19, the baffle can rotate into the box entrance 19 under the action of the top hinge. When the bee separates from the baffle, the baffle returns to its natural hanging state under the action of natural gravity.

[0056] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
