DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments of the present technical solution will be described below in conjunction with the accompanying drawings. Figure 1 to the accompanying drawings Figure 10 The technical solutions in the embodiments of the present technical solution will be described below in conjunction with the accompanying drawings.

[0044] It should be noted that the directions involved in the embodiments of the present technical solution are based on the drawings shown, for example, front, back, left side of the left, right side of the right, front side of the front, rear side of the rear, as shown in the drawings, the left-right direction is the horizontal direction, and the up-down direction shown in the drawings is the vertical direction. If a certain specific posture changes, the directional indication also changes accordingly. Figure 1 Figure 1 Figure 1 Figure 1 Figure 1 Figure 1

[0045] In order to better approach nature and facilitate observation of the foraging conditions of birds from different angles, the present technical solution provides a bird feeder, which is provided with a camera device 3 on the bird foraging device, and the angle of the camera device 3 can be adjusted to observe the foraging conditions of birds under control.

[0046] As shown in the feeder of the present technical solution, Figure 1 which is similar to a house shape, has a shell 1, the shell 1 has a material chamber 11 for containing materials and a camera device 3 for facilitating observation of bird feeding, the lower part of the shell 1 is connected with a material tray 4, the upper part of the shell 1 is detachably connected with a top cover 6, and the shell 1 can be further connected with a solar power supply panel (not shown in the figure), which is used to provide power supply for the camera device 3 and a signal receiving and transmitting device 8. Figure 1

[0047] As shown in the drawings, Figure 1 , Figure 3 and Figure 6 , the shell 1 has a material chamber 11 for containing materials, the area of the shell 1 towards the material tray 4 has a groove 12 recessed into the material chamber 11, the groove 12 has a groove wall 121 and an opening 122 communicating with the outside, and the groove 12 has at least a camera device 3 capable of pointing to the material tray 4; the groove 12 has a first connection adjusting device 2 assembled with the groove wall 121, the first connection adjusting device 2 is assembled with the camera device 3, and the first connection adjusting device 2 is capable of adjusting the angle of the camera device 3 under control.

[0048] Further, as shown in the drawings, Figures 4-1 to 4-2 the first connection adjusting device 2 is capable of adjusting the up-down movement or left-right rotation or forward-backward movement of the camera device 3 under control.

[0049] In detail, as shown in the drawings, Figure 2 ​​​​​​​As shown, the first connection adjustment device 2 includes two side arms 22, which are connected by a horizontal bracket 21. The horizontal bracket 21 has a small hole 211 for connecting a detachable component. The two side arms 22 are respectively connected to the groove wall 121 of the groove 12 through an adjustment device. The camera device 3 is connected to the horizontal bracket 21 through the detachable component.

[0050] Furthermore, the small hole 211 is elongated, providing the detachable component with a certain space for positional movement, allowing the detachable component to move within the small hole 211. Of course, the small hole 211 is not limited to an elongated shape; it can be any other shape, as long as the small hole 211 provides enough space for the detachable component to move.

[0051] In this embodiment, when the detachable component is connected to the camera device 3, the camera device 3 moves back and forth in the small hole 211 by the detachable component, thereby moving back and forth in the groove 12, thereby realizing the adjustment of the camera angle of the camera device 3.

[0052] In another application scenario, since the detachable component includes a nut 241 and a screw 242, the left and right rotation angle of the camera device 3 can be adjusted by adjusting the rotation tightness of the camera device 3 and the screw 242, thereby achieving the camera angle adjustment of the camera device 3.

[0053] In addition to the two application scenarios mentioned above, in another application scenario, the camera device 3 can also move up and down in the groove 12 to adjust the up and down camera angle of the camera device 3.

[0054] Specific examples Figure 5 As shown, the first connection adjustment device 2 rotates from 0° to 180° towards the opening 122 of the groove 12 by rotating the adjustment device connected to the groove wall 121 of the groove 12.

[0055] In addition, the adjustment device can also enable the first connection adjustment device 2 to rotate and maintain a suspended state at an angle after balancing the external force.

[0056] The adjustment device includes a connecting part, which is integrally formed and connected to the side arm 22. The connecting part includes a first rotating member 2311, and a second rotating member 2312 is connected to the first rotating member 2311. The diameter of the second rotating member 2312 is smaller than that of the first rotating member 2311.

[0057] When the first connecting adjustment device 2 is rotationally connected in the second small hole 123, the first rotating part 2311 can rotate relative to the second small hole 123.

[0058] Therefore, the camera device 3 in the technical scheme can move up and down in the groove 12 to adjust the camera angle up and down.

[0059] However, when the first connecting adjustment device 2 needs to be kept in a suspended fixed state, the adjustment device further comprises a stop part 232, as shown in the figure. Figure 2 As shown, the stop part 232 comprises a hollow inner spiral structure in the first rotating part 2311, which is connected with a second screw. Further, the stop part 232 further comprises a ring-shaped disc 2321, which has at least one annular protrusion on one side, and the side edge of the annular protrusion extends to the edge of the ring-shaped disc with a strip-shaped protrusion 2323; the corresponding outer side edge of the second small hole 123 has at least one strip-shaped groove corresponding to the strip-shaped protrusion 2323; further, the adjustment device further comprises a ring-shaped non-slip pad 233, which separates the direct contact between the second screw and the ring-shaped disc 2321.

[0060] It can be understood that when the first connecting adjustment device 2 needs to be kept in a suspended fixed state, after the first rotating part 2311 is clearance-fitted in the second small hole 123, the second rotating part 2312 is completely exposed on the outer side surface of the second small hole 123, and the ring-shaped disc 2321 is sleeved on the second rotating part 2312 and adjusted to the strip-shaped protrusion 2323 clamped in the strip-shaped groove, so that the ring-shaped disc 2321 cannot move in position. Further, after the second screw is assembled in the hollow inner spiral structure, the surface of the second screw abuts against the ring-shaped disc 2321, which not only rotationally connects the second connecting adjustment device 2 on the groove wall 121, but also realizes the front and back movement of the second connecting adjustment device 2 in the groove 12 by assembling and fitting the ring-shaped disc 2321 and the strip-shaped groove.

[0061] The left and right movement of the camera device 3 caused by the second connecting adjustment device 2 is defined as the X-axis, the up and down movement of the camera device 3 is defined as the Z-axis, and the front and back movement of the camera device 3 is defined as the Y-axis. When the second connecting adjustment device 2 moves forward and backward, the second connecting adjustment device 2 can cause the camera device 3 to move and stay in a certain angle on a plane formed by any two axes of XY, ZY or XZ.

[0062] However, when the second connecting adjustment device 2 generates rotational movement, the second screw also generates synchronous rotational movement with the second connecting adjustment device 2. After long-term rotational use, the contact between the second screw and the annular disc 2321 will be damaged by friction, so that the first connecting adjustment device 2 cannot be suspended in the groove 12 for a long time.

[0063] Therefore, a non-slip pad 2324 can be arranged at the contact between the second screw and the annular disc 2321, as shown in Figure 3 The non-slip pad 2324 is used to increase the extrusion friction of the contact surface between the second screw and the annular disc 2321, so that the second connecting adjustment device 2 can be suspended in a certain position for a long time.

[0064] Further, as shown in Figure 6 The camera device 3 is provided with a charging interface 31, and a power line 32 is plugged into the charging interface 31. The power line 32 is connected with a solar power supply panel which passes through a wire slot 116 in the shell 1. The solar power supply panel can provide power for the camera device 3 for use in the working of the camera device 3.

[0065] Further, as shown in Figure 7 The shell 1 has a material chamber 11 which can accommodate food. The material chamber 11 is enclosed by a front panel 111 and a rear panel 112 to form a material chamber 11 with a cavity which can accommodate food.

[0066] Further, the material chamber 11 has a feeding opening 113, and a side of the material chamber 11 opposite to the feeding opening 113 has a discharging opening 114.

[0067] Further, the side wall of the material chamber 11 near the bottom has a sliding area 115 which is inclined to the bottom surface of the material chamber 11 at an angle of 20°-80°.

[0068] In detail, when food enters the material chamber 11 from the feeding opening 113, part of the food will contact the sliding area 115 and slide along the inclined surface of the sliding area 115 into the discharging opening 114, and part of the food will come out of the discharging opening 114, so that birds can eat the food from the discharging opening 114.

[0069] In order to replace the cleaning material chamber 11 more conveniently, the front panel 111 and the rear panel 112 are connected in a slide structure, that is, each of the two sides of the rear panel 112 is provided with a slide groove 1121, and the two side edges of the front panel 111 can be clamped in the slide groove 1121. When it is necessary to clean or replace the material, the front panel 111 only needs to be pulled up to separate the bottom of the front panel 111 from the bottom of the rear panel 112, so that a larger discharging area is exposed, and the old food is conveniently removed.

[0070] Further, as shown in Figure 7 The lower part of the shell 1 is further connected with a material tray 4, and the material tray 4 comprises a feeding area 41. When the food is discharged from the discharging port 114, the food flows to the feeding area 41, and the birds can forage in the feeding area 41. It should be noted that the feeding area 41 is just in the shooting field of view of the camera device 3, and when the birds are foraging, the camera device 3 can record the foraging situation of the birds.

[0071] Further, the material tray 4 further comprises a plurality of water leakage holes 42. When it rains, the material tray 4 is easily invaded by rainwater, and a plurality of water leakage holes 42 are arranged on the material tray 4, which can drain away the rainwater to avoid affecting the birds foraging.

[0072] Further, as shown in Figure 7 The intersection of the two side edges and the horizontal edge of the material tray 4 is respectively provided with a third small hole 43, and the third small hole 43 is connected with a stand 10.

[0073] It can be understood that when the birds fly in the air and land on the feeder to forage, the stand 10 can provide a landing buffer area for the birds, so that the birds can better walk into the feeding area 41 to forage.

[0074] However, in order to better protect the food of the birds from wind and sun, further as shown in Figure 1 and Figure 8-1 , Figure 8-2 A top cover 6 can also be arranged above the material chamber 11, the top cover 6 is used for opening or closing the material chamber 11, the top cover 6 presents a conical body, the two sides of the largest part of the top cover 6 are respectively provided with a second connecting rotating part 61, and the second connecting rotating part 61 enables the top cover 6 to rotate relative to the cross section of the material chamber 11 by 0° to 180°.

[0075] Specifically, as shown in Figures 8-1 to 8-2As shown, the second connecting rotating part 61 on both sides includes a recessed part 63 on both sides of the top cover 6 at the largest part and a protruding part 1111 on both sides of the top of the front panel 111, the protruding part 1111 is assembled in the recessed part 63, so that the top cover 6 and the front panel 111 are detachably connected.

[0076] Further, as shown in Figures 8-1 to 8-3 As shown, the recessed part 63 has a limiting part 631, which is a half-circle protrusion arranged along the top surface of the recessed part 63, as shown in Figure 6 As shown, when the top cover 6 is turned over, the recessed part 63 causes the top cover 6 to move from the C position to the D position, the recessed part 63 abuts against the limiting part 631, the top cover 6 cannot continue to rotate, only the active area between the C point and the D point can rotate, thereby realizing the rotation of the top cover 6 relative to the cross section of the material chamber 11 from 0° to 180°.

[0077] Further, as shown in Figures 8-1 to 8-3 As shown, the top of the top cover 6 also includes a first slot hole 62, which can be detachably assembled with a dust cover 7 (not shown in the figure) or an assembly part 64 (not shown in the figure) according to actual practical needs.

[0078] Specifically, the dust cover 7 is used when the top cover 6 does not need to be assembled with the solar power panel, the dust cover 7 is assembled in the first slot hole 62, so that the dust cover 7 can fill the first slot hole 62 so that the first slot hole 62 does not accumulate dust or rainwater.

[0079] However, in another use scenario, the top cover 6 can be assembled with the solar power panel, and the inner spiral hole 641 recessed inward on the assembly part 64 is used to assemble the solar power panel 5.

[0080] In detail, the assembly part 64 is assembled in the first slot hole 62 by a screw, and the inner spiral hole 641 on the assembly part 64 can be assembled with the screw on the solar power panel to realize that the solar power panel is placed above the top cover 6, and fully absorbs solar energy to provide the camera device 3 with a continuous power supply.

[0081] In order to better fix the solar power panel above the top cover 6, and can adjust the angle of the solar power panel towards the sun according to the actual sunshine angle.

[0082] Specifically, as shown in Figure 9As shown, the solar power panel includes a solar panel 50, a power line and a connecting assembly, the connecting assembly is fixed on the back side of the solar panel 50, the connecting assembly includes a fixing seat 511, a first connecting part 512; one end of the fixing seat 511 is fixedly connected with the solar power panel; the other end of the fixing seat 511 is connected with the first connecting part 512; the first connecting part 512 can rotate in any direction around the fixing seat 511.

[0083] Further, the connecting assembly further includes a second connecting part 513, the second connecting part 513 is movably sleeved on the first connecting part 512, the second connecting part 512 is connected with an adapter fixing part 514, it should be noted that the adapter fixing part 514 can have many types, which can be replaced according to the actual use site.

[0084] It should be understood that when the solar power panel is fixedly connected with the bird feeder through the adapter fixing part 514, the angle of the solar panel 50 is adjusted, so that the fixing seat 511 on the back side of the solar panel 50 rotates relative to the first connecting part 512, thereby realizing the adjustment of the sunlight angle of the solar panel 50.

[0085] Further, the power line of the solar power panel can cross the entire upper part of the material chamber 11 along the wire slot 116 on the front panel 111 and the rear panel 112 and be electrically connected with the charging interface 31 of the camera device 3.

[0086] Further, the feeder further includes a signal receiving / transmitting device 8, which is used to transmit the photographed bird foraging information to the service center, so that the user can view the foraging situation of the bird in time, in addition, the food consumption degree of the camera device 3 can be controlled, which is convenient for the user to replace the food material in time.

[0087] Specifically, the power line of the signal receiving / transmitting device 8 is electrically connected with the camera device 3 in the recess 12 through the through slot penetrating the front panel 111 and the rear panel 112, and the solar power panel supplies power to the camera device 3.

[0088] Further, the receiving angle of the signal receiving / transmitting device 8 is adjustable, specifically, the signal receiving / transmitting device 8 can make a bending motion of 0° to 90° relative to the rear panel 112 through the bending structure 81 thereon.

[0089] Further, the feeder further comprises a fixing support 9, which is arranged below the tray 4, and supports the feeder to be fixed on a tree or a wall or the like, and the feeder can be adjusted in angle relative to the tree or the wall after being fixed on the tree or the wall.

[0090] Specifically as shown in Figure 10 The fixing support 9 comprises a fixing end 91, a supporting end 92 and an angle adjusting device 93; the fixing end 91 is used to be fixedly connected on a wall or a tree or the like; the supporting end 92 is in abutting contact with the bottom of the tray 4 to bear the weight of the whole feeder.

[0091] Further, the supporting end 92 extends the angle adjusting device 93, which is circular, and comprises a positioning hole 931 and a plurality of auxiliary positioning holes 932, which are arranged on the periphery of the angle adjusting device 93 at equal distance from the positioning hole 931.

[0092] It should be understood that when the feeder is assembled with the fixing support 9, the feeder is fixedly connected with the tree or the wall through the fixing end 91. In another use scenario, when the assembly angle of the feeder with the tree or the wall needs to be adjusted, the assembly of the feeder with the wall can be completed through the angle adjusting device 93.

[0093] Specifically, two assembly holes are arranged on the tray 4 at positions corresponding to the angle adjusting device 93, and the two assembly holes are symmetrically distributed and are respectively assembled with the positioning hole 931 and the auxiliary positioning hole 932, and the assembly can be connected by screw connection or the like.

[0094] Since the plurality of auxiliary positioning holes 932 are arranged at equal distance from the positioning hole 931, and each auxiliary positioning hole 932 is arranged on the periphery of the angle adjusting device 93 at an interval of 20°. Therefore, after one of the assembly holes is connected with the positioning hole 931, the assembly angle of the feeder relative to the wall is adjusted, preferably at an interval of 20° each time, until the assembly angle is adjusted, and then the other assembly hole is assembled with the auxiliary positioning hole 932 corresponding to the selected angle, so that the feeder obtains a suitable assembly angle.

[0095] The feeding device has the first connecting adjusting device 2 which can adjust the shooting visual field of the camera device 3 from multiple angles, so that the foraging conditions of birds can be observed from multiple angles, and the technical problem of single shooting angle for observing the foraging of birds in the prior art is overcome.

[0096] According to the disclosure and teaching of the above description, those skilled in the art to which the technical scheme belongs can also make changes and modifications to the above embodiments. Therefore, the technical scheme is not limited to the specific embodiments disclosed and described above, and some modifications and changes of the technical scheme should also fall within the protection scope of the claims of the technical scheme. In addition, although some specific terms are used in the specification, these terms are only for convenience of description and do not constitute any limitation on the technical scheme.
