Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of breeding, and particularly relates to a feeding device for outdoor geese in a breeding farm. BACKGROUND

[0002] With the continuous development of the breeding industry in the direction of scale and intelligence, the traditional outdoor feeding method of poultry cannot meet the multiple requirements of modern breeding for high efficiency, hygiene and energy saving. In particular, in a free-range or semi-open breeding environment, how to achieve precise feeding with timing, quantity and pollution prevention has become a key challenge faced by the industry. At present, the breeding farm mainly adopts two ways of manual feeding and simple automatic equipment. However, most small breeding farms or farmers still rely on manual feeding, which not only consumes time and effort, but also often leads to uneven feeding, resulting in the accumulation of feed in some areas and insufficient feed in other areas. In addition, in rainy days, the feed that has not been eaten by poultry is easily wetted and wasted. On the other hand, the simple automatic equipment on the market also has obvious defects: first, these devices still need regular manual inspection and feed replenishment; second, the devices are prone to blockage, which leads to delayed feeding and affects breeding efficiency.

[0003] In view of this, in order to solve the above problems, the application provides a feeding device for outdoor geese in a breeding farm, which can automatically supplement the feed according to the internal feed condition of the feeding mechanism, effectively prevent blockage, and ensure timely feeding. This device has high automation degree, can save time and effort, and significantly improves breeding efficiency. SUMMARY

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] See Figures 1-9 An outdoor goose feeding device for a farm includes a support frame 1 and a storage bin 2 fixedly mounted on the support frame 1. A feeding mechanism 3 is located on one side of the storage bin 2. The lower end of the storage bin 2 is connected to a conveying mechanism 4 via a feeding pipe. Multiple feeding pipes 5 are connected to the conveying mechanism 4, each equipped with an electrically controlled valve. The output ends of the feeding pipes 5 are connected to a feeding mechanism 6. An anti-blocking component 7 is installed inside the feeding mechanism 6. The feeding mechanism 3, the electrically controlled valves, the conveying mechanism 4, and the anti-blocking component 7 are electrically connected to a controller. Specifically, the storage bin 2 adopts... The feeding mechanism 3 is arranged along the height of the storage bin 2 using an inverted cone structure design. The feeding pipe at the lower end of the storage bin 2 is equipped with a flange connection. The flange is detachably connected to the conveying mechanism 4 by bolts. The multiple feeding pipes 5 set on the conveying mechanism 4 can extend in different directions according to the actual outdoor layout. Their length can also be determined according to the site distance. The feeding pipes 5 can be made of PP pipe material. Their output end is connected to the feeding mechanism 7. The controller can be a PLC controller or a single-chip microcomputer in the existing technology to control all electrical control components in this device. During operation, the controller controls the conveying mechanism 4 to transport the feed stored in the storage bin 2 to each feeding pipe 5, and then from the feeding pipe 5 to each feeding mechanism 6. Combined with the control activation of the anti-blocking component 7, blockage of the feeding mechanism 6 can be effectively prevented. When there is a shortage of feed in each feeding mechanism 6, the controller will control the conveying mechanism 4 to automatically replenish the feed, thereby realizing automatic feed replenishment, ensuring timely feeding, and significantly improving breeding efficiency.

[0027] The feeding mechanism 6 includes a feeding disc 601 and a storage bin 602. The feeding disc 601 has an arc-shaped protrusion 603 in the middle and an evenly spaced fixed bracket 604 along its circumference. The storage bin 602 is installed on the fixed bracket 604. The output end of the feeding pipe 5 is located directly above the storage bin 602. The anti-blocking component 7 is installed inside the storage bin 602. Specifically, the feed hopper 602 adopts a structure that is wider at the top and narrower at the bottom, allowing the feed to fall naturally under gravity. The fixing platform 604, with its side design higher than the connection point of the arc-shaped protrusion 603, creates a gap between the feed hopper 602 and the arc-shaped protrusion 603, facilitating feed passage. In use, geese eat in the feeding tray 601. As the feed gradually decreases, the feed in the feed hopper 602 overflows from the gap into the feeding tray 601 due to gravity, allowing the geese to continue eating. The anti-blocking component 7 is designed to effectively prevent clogging during the overflow process.

[0028] Infrared sensors are installed on the lower inside of the storage hopper 602 and the lower inside of the storage bin 2, respectively, and the infrared sensors are electrically connected to the controller. Specifically, infrared sensors can be installed in the lower part of the storage bin 602 and the storage hopper 2, and infrared sensors commonly used in the prior art can be adopted. This design can issue an early warning to the staff to replenish the feed when the feed in the storage hopper 2 is lower than the preset value. At the same time, when the feed in the storage bin 602 is insufficient, the controller can automatically control the internal feed to be replenished, thereby saving time and manpower.

[0029] The upper end of the storage hopper 602 is provided with a rain cover 605. The diameter of the rain cover 605 is larger than the diameter of the feeding tray 601. The output end of the feeding pipe 5 passes through the rain cover 605 and extends downward. Specifically, the rain cover 605 adopts a conical structure and is detachably connected to the upper end of the storage hopper 602 by bolts. The feeding pipe 5 passes through the middle of the rain cover 605, and the rain cover 605 can also be detachably connected to the feeding pipe 5 by bolts to increase the overall stability of the storage hopper 602. The diameter of the rain cover 605 is designed to be larger than the size of the feeding tray 601 in order to effectively prevent rainwater from falling into the feeding tray 601 in rainy weather and avoid the feed from getting damp.

[0030] The anti-clogging component 7 includes a stirring motor 701, a stirring shaft, and stirring rods 702. The stirring motor 701 is disposed inside the arc-shaped protrusion 603. The output end of the stirring motor 701 is connected to the stirring shaft. The end of the stirring shaft passes through the arc-shaped protrusion 603 and extends upward. Multiple stirring rods 702 are axially spaced on the upper side of the arc-shaped protrusion 603, and the stirring rods 702 are inclined downward. The stirring motor 701 is electrically connected to the controller. Specifically, a mounting groove for mounting the mixing motor 701 can be formed at the center of the lower end face of the feeding tray 601 along the arc-shaped protrusion 603. This mounting groove extends upward to form a through hole for the mixing shaft to pass through. The upper end of the mixing shaft is detachably connected to a sleeve by bolts, and multiple mixing rods 702 are evenly spaced around the outer periphery of the sleeve. In use, the controller controls the mixing motor 701 to operate, driving the mixing shaft to rotate, which in turn causes the multiple mixing rods to rotate synchronously, effectively agitating the feed to prevent blockage.

[0031] The feeding mechanism 3 includes a mounting frame 301, a mounting plate 302, a sprocket 303, a chain 304, a feeding hopper 305, an electric telescopic rod 306, and a drive motor. The mounting frame 301 is located on one side of the storage bin 2, and the upper end of the mounting frame 301 is higher than the storage bin 2. The two sides of the upper and lower ends of the mounting frame 301 are respectively connected to the sprocket 303 by a rotating shaft. The two sprockets 303 on the same side are connected by a chain 304. The sprockets 303 are driven to rotate by the drive motor. The mounting plate 302 is located on the two chains 304 on the side away from the storage bin 2. The mounting plate 302 is fixedly connected to the two sides of the mounting plate 302. The two sides of the feeding hopper 305 are rotatably connected to the mounting ears 307 by a shaft. The two sides of the mounting plate 302 are respectively provided with electric telescopic rods 306. The output ends of the two electric telescopic rods 306 are rotatably connected to the two sides of the feeding hopper 305. The electric telescopic rods 306 and the drive motor are electrically connected to the controller. Specifically, the mounting frame 301 consists of two symmetrically arranged columns and multiple crossbeams positioned between them. Each of the two columns has a horizontally rotating shaft at its upper and lower ends, with both ends extending outwards through the columns. A sprocket 303 is fitted onto each end of the shaft, and the two sprockets 303 on the same side are connected and rotated by a chain 304. One of the shafts is driven by a drive motor, allowing the shafts on the two columns to rotate synchronously. In the initial state, the mounting plate 302 is located below the two chains 304, facilitating the pouring of feed into the feeding hopper 305. Two electric telescopic rods 306 are rotatably connected to the lower part of the mounting plate 302, and their output ends are rotatably connected to both sides of the feeding hopper 305 via connectors. When feed is added to the storage bin 2, the controller activates the drive motor, causing the two sprockets 303 to rotate, thus moving the feeding hopper 305 upwards. When the upper end of the mounting plate 302 reaches the upper end of the two columns, the controller stops the drive motor and then controls the two electric telescopic rods 306 to work, pushing the feeding hopper 305 so that its opening end faces the storage bin 2, and pouring the internal feed into the storage bin to complete the feed replenishment.

[0032] The mounting plate 302 is provided with an inverted T-shaped slider 308 on the side near the mounting bracket 301, and the mounting bracket 301 is provided with an inverted T-shaped groove 309 suitable for sliding the inverted T-shaped slider 308. Specifically, inverted T-shaped sliders 308 are symmetrically arranged on the upper and lower sides of the mounting plate 302. The design of the inverted T-shaped sliders 308 ensures the stability of the mounting plate 302 during the up and down movement.

[0033] Mounting bases 8 are fixedly installed on both sides of the mounting bracket 301 below the mounting plate 302. The mounting base 8 is provided with a buffer spring 9, and the top of the buffer spring 9 is provided with a buffer platform that contacts the lower end of the mounting plate 302. Specifically, each of the two columns is welded with a mounting base 8, and a buffer spring 9 is fixedly mounted on the mounting base 8. A buffer platform is fixedly connected to the top of the buffer spring 9, and the buffer platform is in contact with the lower end face of the mounting plate 302 in its initial state. After the mounting plate 302 moves upward, the upper end face of the buffer platform is slightly higher than the inverted T-shaped groove on the lower side. When the mounting plate 302 returns to its original position, the spring force of the buffer spring 9 can provide a buffering effect.

[0034] The conveying mechanism 4 includes a support frame 401 and a screw conveyor 402 mounted on the support frame 401. The lower end of the storage bin 2 is connected to the screw conveyor 402 through a discharge pipe. Multiple feeding pipes 5 are connected at intervals to the lower surface of the screw conveyor 402, and all multiple feeding pipes 5 are arranged downwardly. The screw conveyor 402 is electrically connected to the controller. Specifically, the screw conveyor 402 is detachably connected to the support frame 401 via bolts and adopts a tubular screw conveyor structure design commonly used in the prior art. The inlet ends of multiple feeding pipes 5 are all connected to the lower surface of the screw conveyor 402. To ensure smoother feed transport, the feeding pipes 5 are designed to be arranged at a downward angle. In operation, the controller controls the screw conveyor 402, allowing the feed in the storage silo 2 to be transported to each storage bin 602 via the multiple feeding pipes 5, thus replenishing the feed.

[0035] Working principle of the invention: When adding feed to storage bin 2 for the first time: First, pour the feed into the feeding hopper 305, and the controller controls the drive motor to drive the two sprockets 303 to rotate, thereby moving the feeding hopper 305 upward. When the upper end of the mounting plate 302 reaches the upper end of the two columns, the controller stops the drive motor and then controls the two electric telescopic rods 306 to push the feeding hopper 305 so that its opening end faces the storage bin 2, and pour the feed inside into the storage bin. This process is repeated to complete the addition of feed to storage bin 2. When adding feed to each storage bin 602 for the first time: the controller controls the opening of the electrically controlled valves on each feeding pipe 5, and the controller controls the screw conveyor 402 to work, so that the feed in the storage bin 2 is transported to each storage bin 602 through multiple feeding pipes 5. When the feed in the storage bin 602 is sufficient, the screw conveyor 402 can be turned off. When the infrared sensor inside the storage hopper 602 detects that the feed in the hopper is insufficient, the controller will first close the electrically controlled valves of other feeding pipes 5, then open the electrically controlled valves on the feeding pipe 5, and start the screw conveyor 402, thereby replenishing the feed in the storage hopper 602. The feed replenishment method for other storage hoppers 602 is the same. When the infrared sensor in the storage bin 2 detects that the feed in the bin is insufficient, the controller controls the drive motor to work, which drives the two sprockets 303 to rotate, thereby moving the feeding hopper 305 upward. When the upper end of the mounting plate 302 reaches the upper end of the two columns, the controller stops the drive motor and then controls the two electric telescopic rods 306 to work, pushing the feeding hopper 305 so that its opening end faces the storage bin 2, and pouring the feed inside into the storage bin to complete the feed replenishment.

[0036] Furthermore, the feeding device of this invention features a high degree of automation, enabling automatic feed replenishment without manual intervention, saving time and reducing manpower. In addition, the anti-clogging component effectively prevents blockages, ensuring timely feeding and significantly improving breeding efficiency.
