Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of beekeeping equipment, in particular to a multifunctional nest door with external feeding, magnetic attraction, rotation and fixation. BACKGROUND

[0002] The beehive is a basic beekeeping machine for artificially feeding bees, and the nest door is an important part of the beehive, which is the passageway for bees to enter and exit the beehive and the portal directly connected to the outside world. The nest door is of great significance to the feeding and management of bees. At present, the nest door used for beekeeping is basically made of pine or cedar with the same length and width as the beehive. A small cuboid that can be horizontally rotated and closed and opened is fixed on the lower side of the cuboid by a nail shaft. The large cuboid is fixed at the entrance of the beehive, and the bottom of the small cuboid is attached to the bottom plate of the beehive. According to the needs of the bee colony, the large cuboid is opened and separated, or the size of the small door is changed by rotating the small cuboid.

[0003] However, the nest door in the prior art still has the following problems in use:

[0004] 1. When the large cuboid is fixed with the beehive, iron nails are needed for fixation, and the nails need to be removed when the door is opened, which can easily damage the nest door and the beehive;

[0005] 2. The small cuboid and the large cuboid are fixed and connected by iron nails, the nail shafts are prone to rust, corrosion and breakage, the small cuboid cannot be normally opened and closed, and the service life is short;

[0006] 3. When the bee colony closes the nest door, it is necessary to knock and fix the iron nails to prevent the nest door from being reopened, which has a great impact on the bee colony, and the bees become violent. Similarly, when the nest door is opened, the bees will also be stimulated to become violent, and the operation is complicated;

[0007] 4. The wooden nest door is easily damaged by bees and cannot effectively block the bees. The wooden nest door is deformed, rotted and has a short service life, high replacement frequency and high cost.

[0008] 5. The nest door is of natural wood grain color, which reduces the ability of bees to recognize the nest and easily leads to loss of bees.

[0009] 6. The current nest door only has the function of allowing bees to pass when it is opened and blocking bees when it is closed, and the function is single.

[0054] The main nest door body 35 and the auxiliary nest door 5 are respectively mixed with yellow, blue, cyan and purple colors except red to enhance the discrimination ability of bees. Bees have a keen sense of color perception, so using different colors to identify different nests can help them find their own homes more easily. This practice can also reduce the risk of bees getting lost or mistakenly entering other nests. Bright and contrasting colors such as yellow, blue, cyan and purple can make the nest more visible in the environment, making it easier for bees to find it. This design takes advantage of the sensitivity of bees to visual stimuli, providing them with better navigation and positioning clues, which helps them find their own nests more quickly.

[0055] When solid feed or powder for preventing and treating bee disease or slow-release agent is needed, open the upper cover 1 of the solid feed box outside the box, drive out the bees in the solid feed box 10, and directly put in the solid feed, bee medicine, and close the cover.

[0064] The first smoking area 17 is formed by the fixed connection of the "[ ]" type surrounding plate, the bottom plate and the lower part of the inner end plate, the width of the "[ ]" type surrounding plate to the inner end plate 16 of the main nest door is 2.5-3.5 cm, the first smoking area 17 is located in the middle of the nest door and is symmetrically distributed on the left and right, the height of the " " type middle partition 36 is the same as the height of the door of the beehive 32, the thickness is the same as the thickness of the front wall of the beehive 32, and the width is the same as the thickness of the partition plate, the nest door is not only suitable for single king group beehives, but also suitable for nest box double king group beehives with partition plates installed in the middle or nest box king group beehives with partition king grids installed in the middle, and the like, which is flexible and universal.

[0065] The working principle of the present application is that the main body material of the nest door is ABS, which is waterproof, moisture-proof, anti-aging and non-deformable, and cannot be damaged by bees, and is solid and durable. Meanwhile, the auxiliary nest door 5 and the main nest door body 35 are connected by an ABS shaft, which is wear-resistant and durable and does not rust. When the auxiliary nest door 5 is closed, the convex block 7 on the upper end of the side end plate 3 of the beehive 32 automatically inserts into the groove 39 of the opening slot 12, which is firm and reliable. When the auxiliary nest door 5 is opened, it only needs to be slightly rotated to open the opening slot 12, which eliminates the trouble of fixing and opening the auxiliary nest door 5 by nails, and is convenient and flexible, without damage to the beehive 32 and the nest door.

The symmetric two rotating parts 6 keep the installed nest door in place in the left, right, up and down directions of the door of the beehive 32. When the nest door is installed, the outer end vertical buckle 13 is rotated to the horizontal limit block 34, and then the nest door is pushed against the door of the beehive 32 from the outside to the inside along the bottom of the box. The surface of the side end plate 9 on the side close to the inner end plate 16 is provided with a magnet 15 fixedly connected in the magnetic groove 14, which is matched with the iron sheet 33 symmetrically arranged on the two side walls of the door of the beehive 32, and automatically magnetically fixes the nest door. Then the outer end vertical buckle 13 on the surface of the outer end plate 3 is rotated to the vertical limit block 34, which drives the inner end vertical buckle 13 to hook the inner surface of the lower end of the upper wall of the door of the beehive 32, so that the nest door is fixed more firmly and cannot be moved in the left and right directions. The magnetic attraction between the magnet 15 and the fixed iron sheet 33, the rotation of the symmetric vertical buckle 13 and the symmetric rotating part 6 together enhance the firmness of the nest door. When the nest door is opened, the outer end vertical buckle 13 on the surface of the outer end plate 3 is rotated from the vertical limit block 34 to the horizontal limit block 34, which drives the inner end vertical buckle 13 to separate from the inner surface of the lower end of the upper wall of the door of the beehive 32, and then the nest door is opened by slightly using force from the inside to the outside, so that the nest door is separated from the beehive 32 without being fixed by nails, which is convenient and fast, not easy to damage and has a long service life.

[0066] The upper cover of the solid feed box 10 and the flow control box 23 is arranged in a slope shape, which is high inside and low outside. After water, it will flow to the outside along the slope, effectively preventing water from entering the beehive 32. The height of the fence of the first feeding area 17 is the same as the height of the door of the beehive 32. Not only effectively prevents the direct invasion of wind from the auxiliary nest door 5, but also prevents the theft of liquid feed by the bees in the group. At the same time, the nest door is a multifunctional integrated design of a special nest door for bees, which is free of opening the box to feed liquid feed, solid feed, pesticide, magnetic attraction rotation fixation and the like. The heat preservation layer 30 is arranged at the outermost layer of the nest door, that is, at the outer layer of the flow control box 23 and the solid feed box 10. The upper cover 1 of the solid feed box and the upper cover 21 of the flow control box are matched with the heat preservation layer cover plate mounting piece 31. The heat preservation layer 30 has the functions of heat preservation, heat insulation and cooling resistance, which is beneficial to the bees to suck the constant-temperature feed, reduces the influence of the external harsh climate on the bee colony, maintains the normal living environment, and is environmentally friendly, durable, saves materials, reduces cost, and is convenient and fast to apply. The multifunctional effect is remarkable. (Note: Liquid feed includes water, honey, syrup, etc.; solid feed includes sugar powder and honey kneaded together, bee pollen cake, and bee substitute powder cake)

[0067] The feeding pipe 281 of the present application is connected with a pressure storage liquid feed container. When feeding, only the valve 284 of the feeding pipe 281 needs to be opened. When solid feed or powder for preventing and treating bee disease or slow-release agent is needed, the upper cover 1 of the solid feed box is opened outside the box, the bees in the solid feed box 10 are driven out, and the solid feed or bee medicine is directly put in. After closing the upper cover, the bees obtain the solid feed from the feeding port 29 in the beehive, which eliminates the complicated, laborious and tedious operation of opening the box for feeding and applying medicine, and the pain of bee stings.

[0068] By setting the flow control assembly 2, the liquid feed from the feed pipe 281 into the flow control box 23, and finally to the first and second feeding area for bees to suck, the outside of the box is connected to the feed pipe 281 to transport the feed, which solves the feeding of bees, the first feeding area 17 discharge seam spacing <3mm, the second feeding area 38 L-shaped grid 40 gap <3mm, effectively blocking bees and impurities from entering the first and second feeding areas into the floating body 24 area in the flow control box 23, ensuring the normal lifting of the floating body 24, the first feeding area 17 and the second feeding area 38 are connected to each other The channel width and height distance > 5mm, ensuring that bees in the two areas can pass through each other to eat, when the beehive 32 is not placed flat, the bees in the first feeding area 17 and the second feeding area 38 will eat the feed, ensuring that there is no remaining liquid feed at the bottom of the floating body 24, effectively preventing the phenomenon of the floating body 24 being connected to the bottom plate of the flow control box 23 due to the remaining liquid feed drying and solidifying, maintaining the stability of the liquid level, the bottom plate of the flow control box 23 is fixedly connected with two symmetrical first feeding areas 17 on both sides, and the "ㄒ" type partition plate 36 is fixedly connected between the two first feeding areas 17. The height of the "ㄒ" type partition plate 36 is equal to the height of the nest door of the beehive 32, the thickness is equal to the thickness of the front wall of the beehive 32, and the width is the same as the thickness of the partition plate. It is not only suitable for single queen group beehives 32, but also suitable for nest boxes with partition plates installed in the middle of the double queen group beehives 32, or nest boxes with partition plates installed in the middle of the queen group beehives 32. Flexible and versatile, and the flow control body 26 is a detachable device, which can directly feed the bees by opening the flow control upper cover 21 in special circumstances. In some cases, special adjustments may be needed for the feeding of bees, such as changes in the needs of specific bee groups or feed formulations. At this time, the feeding can be adjusted flexibly by opening the flow control upper cover 21.
