Description

Technical Field

[0001] The present invention relates to the technical field of poultry farming, and particularly to a feeding device capable of automatically driving away birds. Background Art

[0002] Free-range chickens are a type of chicken raised by free-range farming in an ecological planting and breeding combination mode. This mode can not only improve the quality of chickens but also bring great benefits to the improvement of the surrounding ecological environment. Most of the existing automatic feeding devices in free-range chicken farms on the market are relatively simple in setting, such as automatic feeding and discharging hoppers. Such devices often do not have a structure for driving away birds. When chickens are free-range, they usually need a large space, which is not convenient for people to manage. There are often some small birds eating chicken feed, resulting in a certain amount of waste. Therefore, an automatic feeding device for free-range chicken farms is proposed to solve the above problems. Summary of the Invention

[0003] In view of the above problems, the present invention relates to a feeding device capable of automatically driving away birds.

[0004] To achieve the above object, the present invention provides the following technical solution: A feeding device includes a bottom plate, a barrel outer shell, and a barrel inner shell. It is characterized in that: the barrel outer shell surrounds the barrel inner shell and is arranged above the bottom plate together with the barrel inner shell. A fixed rod is arranged inside the barrel inner shell, and the barrel inner shell is fixed to the bottom plate through the fixed rod. An installation cylinder is sleeved outside the upper part of the fixed rod. A bearing is installed on the outside of the installation cylinder, and a rotating cylinder is installed between the bearing and the inner wall of the barrel inner shell. The rotating cylinder is connected to a plurality of air guide plates outside the barrel outer shell through a plurality of brackets. The air guide plates are arranged in central symmetry with the rotating cylinder as the center, and the air guide plates can rotate around the rotating cylinder to drive away birds; a first spring is installed outside the lower part of the fixed rod. One side of the first spring abuts against the bottom plate, and a leak-proof block is arranged on the other side of the first spring. A slider is installed inside the leak-proof block. A chute is opened at the corresponding position inside the fixed rod, and the slider is arranged inside the chute. The installation cylinder is arranged on the upper side of the leak-proof block. A limiting structure is installed inside the upper end of the installation. A plurality of through holes are arranged at the position where the barrel outer shell is close to the bottom plate. An arc-shaped groove structure is arranged at the position where the barrel inner shell abuts against the bottom plate. Feed enters through the space between the barrel outer shell and the barrel inner shell and can enter the groove structure through the through holes. A control structure is installed inside the barrel inner shell to control the rotation of the air guide plates.

[0005] Preferably, the upper half of the leak-proof block is conical, the lower half of the leak-proof block is frustum-shaped, the upper half of the inner barrel is frustum-shaped, and the outer diameter of the bottom end of the leak-proof block is the same as the inner diameter of the top end of the inner barrel.

[0006] Preferably, the distance from the top end of the sliding groove to the top end of the fixed rod is equal to the distance from the top end of the slider to the top end of the leak-proof block.

[0007] Preferably, the limiting structure includes a clamping block. An installation groove is formed inside the installation cylinder, and the clamping block can slide inside the installation groove. The top end of the fixed rod is conical, and a clamping groove is formed on the outer side of the upper end of the fixed rod. The clamping block is arranged in the clamping groove. One end of the clamping block is provided with a sliding plate, and a second spring is arranged on the other side of the sliding plate.

[0008] Preferably, a control groove is formed at the top end of the installation cylinder. A cross bar is slidably connected inside the control groove. A control ring is installed on one side of the cross bar, a first pull rope is installed on the other side of the cross bar, and the other end of the first pull rope is installed on one side of the sliding plate.

[0009] Preferably, the control structure includes a control board. The control board is arranged around an arc-shaped groove structure and a third spring is installed at its bottom end. The other end of the third spring is installed on the bottom plate. The bottom end of the control board is installed with a second pull rope in a way that passes through the third spring, and the second pull rope penetrates the bottom plate. The other end of the second pull rope is installed with a control block. The control block is located between the inner side of the inner barrel and the outer side of the rotating cylinder, and one side of the control block is slidably connected with a fixed plate. The fixed plate is installed on the inner side of the inner barrel. A fourth spring is installed on the lower side of the control block, and the other side of the fourth spring is installed with a support frame. The support frame is installed on the inner side of the inner barrel. By pressing the control board to drive the second pull rope to move, the control block is driven to be clamped to the rotating cylinder, thereby stopping the guide vane from rotating.

[0010] Preferably, the surface of the fixed plate where it slides with the control block is inclined inward, and the third springs are evenly distributed on the top surface of the bottom plate.

[0011] The present invention has the following beneficial effects: 1. By setting the installation cylinder, bearing, rotating cylinder, bracket, etc., when the device is placed, the rotation of the air guiding plate can be driven by the air flow, so as to achieve a better bird repelling effect, effectively avoiding the stealing of chicken feed by small birds such as sparrows; 2. By setting the anti-leakage block, first spring, slider, etc., after the air guiding plate is removed, the anti-leakage block can automatically move upward, thus blocking the top of the inner shell of the barrel, facilitating the addition of feed, and effectively preventing the feed from falling into the inner side of the inner shell of the barrel; 3. By setting the control board, second pull rope, fixing plate, control block, etc., when the chicken eats the feed, stepping on the control board with the chicken claw can stop the rotation of the rotating cylinder and the air guiding plate, thus avoiding the influence of the air guiding plate on the chicken and ensuring that the chicken can eat the feed normally; 4. By setting the clamping block, first pull rope, control ring, etc., not only can the clamping block be clamped on the outside of the fixing rod to facilitate the installation of the air guiding plate, but also the air guiding plate can be directly removed by pulling the control ring for use.

[0027] Embodiment

[0028] The following are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the following embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention.

[0029] Refer to the attached drawings of the specification Figures 1-8 , a feeding device, comprising a bottom plate 1, a barrel outer shell 2 and a barrel inner shell 3. The top surface of the bottom plate 1 is installed with the barrel inner shell 3. The barrel outer shell 2 is installed on the outside of the barrel inner shell 3 through connecting columns. A fixing rod 4 is installed inside the barrel outer shell 2. An installation cylinder 5 is installed on the outside of the fixing rod 4. A bearing 6 is installed on the outside of the installation cylinder 5. A rotating cylinder 7 is installed on the outside of the bearing 6. Brackets 8 are evenly installed on the outside of the rotating cylinder 7. A wind guiding plate 9 is installed on the outside of the brackets 8;

[0030] A first spring 10 is installed on the outer side of the fixed rod 4. One side of the first spring 10 is in contact with the bottom plate 1, and a leak-proof block 11 is provided on the other side of the first spring 10. A slider 12 is installed inside the leak-proof block 11. A chute 13 is formed inside the fixed rod 4, and the slider 12 is arranged inside the chute 13. An installation cylinder 5 is provided above the leak-proof block 11; a limiting structure is installed inside the upper end of the installation cylinder 5, and a control structure is installed inside the inner shell 3 of the barrel; a plurality of through holes are provided at the position where the barrel outer shell 2 is close to the bottom plate, and an arc-shaped groove structure is provided at the contact position between the inner shell 3 of the barrel and the bottom plate 1. Feed enters through the space between the barrel outer shell 2 and the inner shell 3 of the barrel and can enter the groove structure through the through holes. A control structure is installed inside the inner shell 3 of the barrel to control the rotation of the air guide plate 9.

[0031] The upper part of the leak-proof block 11 is conical, and the lower part of the leak-proof block 11 is frustum-shaped. The upper part of the inner barrel 3 is frustum-shaped, and the outer diameter of the bottom end of the leak-proof block 11 is the same as the inner diameter of the top end of the inner barrel 3. The distance from the top end of the chute 13 to the top end of the fixed rod 4 is equal to the distance from the top end of the slider 12 to the top end of the leak-proof block 11. This setting can automatically seal the top end of the inner barrel 3 when the rotating cylinder 7 is removed, facilitating the addition of feed. The limiting structure includes a clamping block 14. An installation groove is provided inside the installation cylinder 5, and the clamping block 14 slides inside the installation groove. The top end of the fixed rod 4 is conical, and a clamping groove is provided on the outer side of the upper end of the fixed rod 4. The clamping block 14 is arranged in the clamping groove. One end of the clamping block 14 is equipped with a sliding plate 15, and a second spring 16 is provided on the other side of the sliding plate 15. This setting can automatically control the clamping block 14 to clamp outside the fixed rod 4 when the rotating cylinder 7 is installed, ensuring the stable installation of the wind guiding plate 9 and facilitating subsequent bird repelling. A control groove is provided at the top end of the installation cylinder 5. A cross bar 17 is slidably connected inside the control groove. A control ring 18 is installed on one side of the cross bar 17, and a first pull rope 19 is installed on the other side of the cross bar 17. The other end of the first pull rope 19 is installed on one side of the sliding plate 15. This setting can quickly release the limiting structure when the rotating cylinder 7 and the wind guiding plate 9 need to be removed, facilitating the removal of the rotating cylinder 7. The control structure includes a control board 20. A third spring 21 is installed at the bottom end of the control board 20, and the other end of the third spring 21 is installed on the bottom plate 1. A second pull rope 22 is installed at the bottom end of the control board 20, and the second pull rope 22 penetrates through the bottom plate 1. The other side of the second pull rope 22 is installed with a control block 23. One side of the control block 23 is slidably connected with a fixing plate 24, and the fixing plate 24 is installed inside the inner barrel 3. A fourth spring 25 is installed on the lower side of the control block 23, and the other side of the fourth spring 25 is installed with a support frame 26, and the support frame 26 is installed inside the inner barrel 3. The sliding surface of the fixing plate 24 and the control block 23 is inclined inward. The number of the third springs 21 is 6 - 10, and the third springs 21 are evenly distributed on the top surface of the bottom plate 1. By pressing the control board to drive the second pull rope 22 to move, the control block 23 is driven to be clamped to the rotating cylinder, and the rotation of the wind guiding plate 9 is stopped. This setting can automatically trigger the control block 23 when the chickens come to eat feed, making the control block 23 fit to the outside of the rotating cylinder 7, so that the rotating cylinder 7 and the wind guiding plate 9 on the rotating cylinder 7 do not rotate, thus not affecting the chickens' eating of feed. When the chickens leave, the control board 20 is driven to reset by the third spring 21, driving the control block 23 to move downward, thus releasing the restriction on the rotating cylinder 7 and the wind guiding plate 9, so that it can continue to rotate with the airflow, and the bird repelling effect can be continuously achieved.

[0032] Workflow: When the device is in use, first put feed between the outer shell 2 of the barrel and the inner shell 3 of the barrel, and then install the installation cylinder 5 and the rotating cylinder 7 on the outside of the fixed rod 4. When installing the installation cylinder 5, the leakage prevention block 11 is squeezed by the bottom end of the installation cylinder 5, so that the first spring 10 is compressed. When the installation cylinder 5 continues to move downward, the fixed rod 4 will squeeze the clamping block 14, making the clamping block 14 received inside the installation cylinder 5. When the installation cylinder 5 moves to the position where the clamping block 14 is flush with the card slot on the fixed rod 4, it is okay. Driven by the reaction force of the second spring 16, the clamping block 14 is clamped into the card slot of the fixed rod 4, thereby realizing the fixation of the installation cylinder 5, and further realizing the limitation of the rotating cylinder 7, the bracket 8 and the air deflector 9. When there is air flow, the air will push the air deflector 9, and then through the installed installation cylinder 5 and the bearing 6, the air deflector 9 is rotated, so that bird repelling can be effectively carried out. When the air deflector 9 needs to be removed, directly pull the control ring 18 inward, which will drive the cross bar 17 to move, thereby pulling the first pull rope 19, and then driving the sliding plate 15 and the clamping block 14 to move outward, so as to release the clamping of the fixed rod 4, and then pull out the fixed cylinder 5. At this time, under the action of the first spring 11, the leakage prevention block 11 will be driven to reset, first sealing the top of the inner shell 3 of the barrel, so as to facilitate the addition of feed. When a chicken comes to eat the feed, the chicken's claws will step on the control board 20, and then the control board 20 will move downward. Under the action of the fourth spring 25 (originally in a compressed state due to the length of the second pull rope 22), the control block 23 is driven to move upward, and the control block 23 is pushed obliquely upward through the fixed plate 24, so that the control block 23 fits with the rotating cylinder 7, and the rotating cylinder 7 and the air deflector 9 stop rotating through friction, so as to facilitate the chicken to eat the feed. When the chicken leaves, the control board 20 is driven to reset by the third spring 21, thereby driving the control block 23 to move downward, so as to release the restriction on the rotating cylinder 7 and the air deflector 9, so that it can continue to rotate with the air flow, and the bird repelling effect can be continued to be achieved.
