Description

Technical Field

[0001] The present invention relates to the technical field of the installation of bumblebee hives, and particularly to a sunshade and cooling device for bumblebee hives in a multi-functional glass greenhouse. Background Art

[0002] Under the soilless cultivation mode of tomatoes in a glass greenhouse, due to the special temperature of tomato crops, many pollinating insects cannot pollinate them. However, bumblebees are not sensitive to the special smell of tomatoes and like pollen. Therefore, bumblebees are the best way to replace artificial mechanical pollination and hormone pollination to achieve 100% pollination of tomatoes. The bumblebee pollination technology originated in the Netherlands, is maturely applied in China and is generally commercially applied, and is an important technical link to achieve high yield in the tomato planting mode in a glass greenhouse.

[0003] The optimal pollination temperature for bumblebees is 20 - 26°C. In summer, when the temperature exceeds 26°C, bumblebees no longer go out for pollination but cool the hive by vibrating their wings. Generally, the opening time of tomato flowers is only 3 days. In a high-temperature state, bumblebees take reducing the temperature inside the hive as the primary purpose, which affects pollination and the lifespan of bumblebees, and thus increases the pollination cost. Therefore, sunshade and cooling of the hive are required in summer;

[0004] In winter, the temperature is low. To ensure that the temperature of the hive is higher than the lower limit temperature, the hive needs to be heated. Direct sunlight is the best heating method. Therefore, it is necessary to maintain the direct sunlight heating of the hive in winter. In addition, there is a honey bag (a bag containing a sugar and honey mixture for bumblebees to eat) in the hive. The hive placed near the ground is likely to attract insects such as fruit flies and ants to invade the hive. The pathogens they carry will have a fatal impact on bumblebees. At the same time, these insects will lay eggs in the hive, affecting the quality and lifespan of the hive;

[0005] In a glass greenhouse, due to the prevention of diseases and pests, pesticides need to be sprayed frequently. When spraying pesticides harmful to bumblebees, it is necessary to cover the hive with a plastic bag to prevent the pesticides from being sprayed on the hive. However, the use of plastic covers will exacerbate the increase in the temperature inside the hive and have an adverse impact on the lifespan of bumblebees.

[0006] In the prior art, in order to achieve the protection and adjustment of the hive, the placement rack of the hive is usually set to a structure similar to a sliding window, and then the sunshade device is installed on the window. By pushing and pulling, the purpose of adjusting the sunshade area and protection of the hive is achieved. However, in the actual installation process, the hive is usually installed among the planted plants in the greenhouse, and in order to prevent moisture and insects, it needs to be suspended and placed at a high position. Therefore, the traditional sliding structure is difficult to achieve convenient adjustment. Summary of the Invention

[0039] The rear side of the side plate 1 penetrates through the gap between adjacent columns 2 and is fixedly tied to the fixing rod 3. The transverse width of the side plate 1 is greater than the interval width between adjacent columns 2. Three groups of clamps 29 are linearly and evenly distributed on the rear side of the side plate 1. The clamps 29 are in a semi-circular ring shape. The clamps 29 are clamped on the front end of the fixing rod 3. Ear seats are provided at both ends of the clamps 29, and the clamps 29 are fixedly tied to the fixing rod 3 through binding ropes passing through the ear seats.

[0040] By setting the cooperation between the clamps 29 and the ear seats, the side plate 1 and the column 2 can be conveniently and quickly fixedly installed on the fixing rod 3.

[0041] An intermediate board 8 parallel to the upper board 4 is provided in the middle of the side plate 1. A pair of semi-circular ring-shaped sleeves 24 distributed vertically are provided on the rear side of the side plate 1. The front end ports of the sleeves 24 extend to the front end face of the side plate 1. A pair of symmetrically arranged ports are provided at the front ends of the pair of vertically distributed sleeves 24.

[0042] By setting the cooperation between the sleeves 24 and the semi-circular ring-shaped rotating rods 22, the rotational installation of the semi-circular ring-shaped rotating rods 22 is realized, and then the folding sunshade net 10 is installed on the semi-circular ring-shaped rotating rods 22, so as to realize the installation of the folding sunshade net 10 on the side plate 1.

[0043] A rear fixing post 26 is vertically arranged in the middle at the rear side of the sleeve 24, and a front fixing post 9 is vertically arranged in the middle at the front end of the side plate 1. The front fixing post 9 is located at the front end of the middle layer plate 8. Arc-shaped end plates 7 in a semi-circular ring shape are arranged at the upper and lower ends on the front side of the side plate 1. The front fixing post 9 is located at the front end of the middle layer plate 8, and the upper and lower ends of the front fixing post 9 are fixed on the arc-shaped end plates 7. A pair of right-angle through holes 17 symmetrical left and right are arranged on both the front fixing post 9 and the rear fixing post 26.

The end of the pull rope 12 on the front fixing post 9 is fixed on the front connecting rod 13, and the end of the pull rope 12 on the rear fixing post 26 is fixed on the rear connecting rod 25.

[0044] By setting the cooperation of the right-angle through holes 17 and a pair of pull ropes 12 distributed front and rear, the semi-circular ring rotating rods 22 distributed left and right are rotated and merged forward to the middle at the front end by pulling the pull rope 12 at the front end, driving the folding sunshade net 10 to unfold, achieving the purpose of sunshade and protection. By pulling the pull rope 12 at the rear end, the semi-circular ring rotating rods 22 slide backward and are received into the sleeve 22, so that the folding sunshade nets 10 are folded and pressed against each other and gathered at the front end of the side plate 1, achieving the purpose of increasing the sunlight-receiving area.

[0045] One end port of the right-angle through hole 17 is located on the front side of the side plate 1, the other end port of the right-angle through hole 17 corresponds to the front connecting rod 13 and the rear connecting rod 25. The middle section of the pull rope 12 extends along the bending of the right-angle through hole 17. A guide wheel 18 is arranged at the front end port position of the right-angle through hole 17. The pull rope 12 is smoothly bent along the guide wheel 18 and extends downward.

[0046] The smooth folding and extension of the pull rope 12 is realized by setting the guide wheel 18.

[0047] A second fixing ring 20 fixedly installed by screws 23 is arranged on the side of the front connecting rod 13 close to the semi-circular ring rotating rod 22. The front end port of the sleeve 24 is fixedly installed with the second fixing ring 20. The upper, lower, left and right ends of both sides of the folding sunshade net 10 are correspondingly fixed on the first fixing ring 19 and the second fixing ring 20.

[0048] By setting the first fixing ring 19 and the second fixing ring 20 to limit the front and rear positions of the folding sunshade net 10, it is avoided that the folding sunshade net 10 extends into the sleeve 24 and causes jamming.

[0049] An opening groove 27 is arranged on the arc outer wall of the sleeve 24. The opening groove 27 is distributed in a circular ring. The rear connecting rod 25 rotates and slides along the circumference of the opening groove 27. The upper and lower ends of the rear connecting rod 25 penetrate through the opening groove 27 and are fixed at the end of the semi-circular ring rotating rod 22.

[0050] By setting the opening groove 27, the upper and lower semi-circular ring rotating rods 22 are connected through the rear connecting rod 25, and the rear connecting rod 25 can rotate along the sleeve 24 and the opening groove 27.

[0051] Adjusting plates 14 are fixedly installed on both the front and rear sides of the lower end of the fixed rod 3. A plurality of sleeve columns 15 are vertically arranged on the adjusting plates 14 at linear intervals. The end of the pull rope 12 extends to the front end of the adjusting plate 14, and a hanging ring 16 corresponding to the sleeve column 15 is arranged at the end of the pull rope 12.

[0052] By setting the cooperation between the sleeve column 15 and the hanging ring 16, the height of the pull rope 12 is limited, so as to achieve the purpose of fixing the extended width of the folding sunshade net 10.

[0053] The actual implementation process is as follows: The side plate 1 is conveniently and fixedly installed on the column 2 through the slider 28, the mounting hole and the bolt. Through the cooperation between the clamp 29 and the ear seat, the side plate 1 and the column 2 are conveniently and quickly fixedly installed on the fixed rod 3. The folding sunshade net 10 with the movable ring 21 is sleeved on the semi-circular ring rotating rod 22.

[0054] After the installation is completed, in summer, by pulling the front pull rope 12, the semi-circular ring rotating rods 22 distributed on the left and right rotate forward to the middle of the front end, driving the side surfaces of the pair of folding sunshade nets 10 distributed on the left and right to unfold, so as to avoid the beehive being directly irradiated by the sun and achieve the effect of shading and cooling the beehive.

[0055] In winter, by pulling the rear pull rope 12, the semi-circular ring rotating rod 22 slides backward and is received in the sleeve 22, so that the folding sunshade nets 10 are folded and pressed against each other and gathered at the front end of the side plate 1, achieving the purpose of increasing the sunlight receiving area and realizing the effect of heating and warming the beehive by the low-temperature sunlight in winter.

[0056] When spraying medicine, by pulling the front pull rope 12, the semi-circular ring rotating rods 22 distributed on the left and right rotate forward to the middle of the front end and are pressed against both sides of the front fixed column 9, so that the pair of folding sunshade nets 10 distributed on the left and right completely enclose the front end of the side plate 1, achieving the purpose of completely blocking the medicine during spraying and avoiding spraying it on the beehive.

[0057] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
