Description

Technical Field

[0001] This utility model relates to the field of bird feeder technology, and in particular to a squirrel-proof bird feeder. Background Technology

[0002] With improved living standards, people have adopted bird feeders for bird watching. Bird feeders are devices placed in outdoor environments such as parks and forests to provide food for wild birds. They are generally installed on the ground or hung from tree branches or supports. Existing bird feeders have a protective cover around the food container, connected to the container by a spring. The feeding trough is located at the bottom of the container. When a squirrel climbs, the protective cover descends, pulling the spring and causing it to deform, thus closing the feeding trough. After the squirrel leaves, the spring returns to its original shape, causing the protective cover to rise and open the feeding trough. This structure is relatively complex, and with prolonged use, the spring's elasticity can easily decrease, causing the protective cover to fail to return to its original position, resulting in the protective cover closing the feeding trough.

[0003] Therefore, it is necessary to provide a squirrel-proof bird feeder to solve the above-mentioned technical problems. Utility Model Content

[0004] This utility model provides a squirrel-proof bird feeder, which solves the problem in the prior art that the protective cover of the squirrel-proof bird feeder does not reset properly and easily closes the feeding trough.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a squirrel-proof bird feeder, comprising a storage box, a protective cover surrounding the storage box and rotatably connected to the storage box at both ends, symmetrically arranged poles on both sides of the protective cover, a counterweight disposed below the protective cover for balancing the poles on both sides, and an opening disposed on the protective cover for birds on the poles to take food from the storage box.

[0006] In this invention, the protective cover is further provided with symmetrical guardrails, which are respectively connected to the side walls of the openings on both sides of the protective cover.

[0007] In this invention, one side of the symmetrical guardrail extends toward the bottom of the protective cover and intersects with it, and the counterweight is connected to the intersection of the guardrails.

[0008] In this invention, feeding slots are provided on both sides of the bottom of the storage box.

[0009] In this invention, the top of the storage box is also provided with a feed inlet for adding grain.

[0010] In this invention, the storage box is further provided with a concave structure arranged along the length of the storage box, and the concave structure is located above the feeding trough.

[0011] In this invention, the bottom of the storage box is an arched structure, and multiple drainage holes are provided on both sides of the bottom of the storage box.

[0012] In this invention, both the storage box and the protective cover are made of transparent material.

[0013] In this utility model, the anti-squirrel bird feeder is also provided with a hook, and the two ends of the hook are respectively fixed to the connection point between the protective cover and the storage box.

[0014] In this invention, a bearing is also provided at the connection point between the protective cover and the storage box.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: When a non-avian animal, such as a squirrel, climbs onto the pergola to steal food, the squirrel's weight is much greater than that of a bird, causing the pergola to become unbalanced and rotate the protective cover. The opening on the protective cover is misaligned with the food storage box, thus blocking the squirrel from stealing food. After the squirrel leaves, the pergola will be reset by the counterweight, without affecting the birds' normal feeding. This can effectively prevent non-avian animals from stealing food.

[0026] The following is a preferred embodiment of a squirrel-proof bird feeder provided by this utility model that can solve the above-mentioned technical problems.

[0027] Please refer to Figure 1 , Figure 2 and Figure 3 ,in Figure 1 This is a perspective view of the squirrel-proof bird feeder of this utility model.

[0029] The terms "first" and "second" in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as a restriction on the order of events.

[0030] This utility model provides a bird feeder to prevent squirrels from eating. It includes a food storage box 12, a protective cover 11 surrounding the food and rotatably connected at both ends, symmetrically arranged poles 112 on both sides of the protective cover 11, a counterweight 115 located below the protective cover 11 to balance the poles 112, and an opening 113 on the protective cover 11 for birds on the poles 112 to access the food from the storage box 12. The food storage box 12 holds bird feed and bird food. The opening 113 in the protective cover 11 allows the food storage box 12 to be opened for easy access to the birds. The poles 112 facilitate birds standing and feeding from the food storage box 12. Since birds are relatively lightweight... When a squirrel climbs onto the perch 112 to eat, due to its weight, the perch 112 rotates towards the bottom of the food storage box 12. As the perch 112 moves, it causes the protective cover 11 to rotate, moving the opening 113 of the protective cover 11 away from the food storage box 12. At the same time, the counterweight 115 moves with the protective cover 11, and the side panel of the protective cover 11 closes the food storage box 12, preventing the squirrel from taking food from the food storage box 12. After the squirrel leaves, the counterweight 115 moves down under its own weight, causing the protective cover 11 to return to its original position, and the opening 113 of the protective cover 11 opens the food storage box 12, making it easier for birds to eat.

[0031] In this embodiment, the weight of the counterweight 115 is greater than the weight of the bird but less than the weight of the squirrel, so as to prevent the protective cover 11 from rotating when the bird stands on the pole 112.

[0032] The protective cover 11 is also equipped with symmetrical guardrails 111, which are respectively connected to the side walls of the openings 113 on both sides of the protective cover 11. The guardrails 111 are used to prevent large debris from entering the protective cover 11 and blocking the feeding trough 121, so as to facilitate birds to eat.

[0033] In this embodiment, the protective cover 11 is square in shape, but it is not limited to square; it can also be circular.

[0034] One side of the symmetrical guardrail 111 extends toward the bottom of the protective cover 11 and intersects. The counterweight 115 is connected to the intersection of the guardrail 111, which facilitates the fixing of the counterweight 115. At the same time, the counterweight 115 is located at the bottom of the guardrail 111, which facilitates the resetting of the protective cover 11.

[0035] In this embodiment, the counterweight 115 is rod-shaped and is fixed at the intersection of the symmetrical guardrails 111, which facilitates the fixing of the counterweight 115.

[0036] Please refer to Figure 4 , Figure 4 This is a perspective view of the storage box of the anti-squirrel bird feeder of this utility model. Both sides of the bottom of the storage box 12 are provided with feeding troughs 121, which are used to facilitate birds to eat from the storage box 12.

[0037] The top of the feed box 12 is also provided with a feed inlet 122 for adding food. The feed inlet 122 is used to facilitate adding food to the feed box 12, so that the bird feeder can be used repeatedly.

[0038] The storage box 12 is also provided with a concave structure 123 arranged along the length of the storage box 12. The concave structure 123 is located above the feeding trough 121. The concave structure 123 makes the upper part of the feeding trough 121 of the storage box 12 concave, preventing the grain from falling out from the direction of the feeding trough 121 and avoiding waste of grain.

[0039] The bottom of the storage box 12 has an arched structure. Multiple drainage holes 124 are provided on both sides of the bottom of the storage box 12. The drainage holes 124 are used to drain the rainwater inside the storage box 12 to prevent the rainwater that accidentally falls into the storage box 12 from accumulating inside the storage box 12 and soaking the grain.

[0040] The protective cover 11 is made of transparent material, which makes it easier for birds to find the food in the food storage box 12 and come over to eat.

[0041] The bird feeder is also equipped with a hook 13. The two ends of the hook 13 are fixed to the connection points of the protective cover 11 and the storage box 12, respectively. The hook 13 is used to conveniently hang the bird feeder on tree branches or supports.

[0042] A bearing 114 is also provided at the connection point between the protective cover 11 and the storage box 12. The bearing 114 is used to reduce the friction force of the protective cover 11 during rotation, so that the protective cover 11 can rotate more smoothly.

[0043] Working principle:

[0044] The grain is poured in from the inlet 122 and moves towards the feeding trough 121. Due to the concave structure 123, the grain is prevented from overflowing from the feeding trough 121, avoiding waste. When birds come to eat, they stand on the perch 112. Since the weight of the birds is less than the weight of the counterweight 115, the protective cover 11 remains stationary, allowing the birds to eat from the opening 113 on the perch 112. When a squirrel climbs onto the perch 112 to eat, since the weight of the squirrel is greater than the weight of the counterweight 115, the squirrel moves the perch 112 towards the other side of the storage box 12. As the perch 112 moves, the protective cover 11 rotates. The opening 113 moves away from the feeding trough 121, and the counterweight 115 moves with the protective cover 11 to one side of the protective cover 11 so that the side wall of the protective cover 11 is opposite to the feeding trough 121, thereby closing the feeding trough 121 and preventing the squirrel from eating. After the squirrel leaves the perch 112, the counterweight 115 moves downward according to its own weight. During the movement of the counterweight 115, the protective cover 11 rotates, so that the protective cover 11 returns to its initial position. The opening 113 of the protective cover 11 opens the feeding trough 121 of the storage box 12, making it easier for birds to eat. The above structure is simple, and the method of resetting the protective cover 11 by the gravity of the counterweight 115 is simple. There is no need to worry about the protective cover 11 not being able to reset after a long period of use, making it more convenient for birds to eat.

[0045] In this preferred embodiment of the squirrel-proof bird feeder, when a non-avian animal, such as a squirrel, climbs onto the pergola to steal food, the squirrel's weight, being much greater than that of a bird, causes the pergola to become unbalanced, causing the protective cover to rotate. The opening on the protective cover misaligns with the food storage box, thus blocking the squirrel from stealing food. After the squirrel leaves, the pergola, under the action of the counterweight, will cause the protective cover to return to its original position, without affecting the birds' normal feeding. This device can effectively prevent non-avian animals from stealing food.

[0046] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
