[0061] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0062] One of the purposes of the present invention is to provide a novel rabbit feeding device to solve the problem that the existing rabbit house feeding device is too high and has an unstable center of gravity, which is not only easy to overturn but also difficult to load.

[0063] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0064] Example 1

[0065] like Figures 1 to 7As shown, this embodiment provides a rabbit feeding device 100, comprising a main frame 1, a feeding unit, a feeding unit 4, and a weighing unit 5. The feeding unit includes a conveyor mounted on the main frame 1, the conveyor being arranged in an up-and-down tilt, and the upper end of the conveyor being used to connect with a rabbit cage food box to transport feed into the rabbit cage food box. The feeding unit 4 is mounted on the main frame 1 and arranged near the lower end of the conveyor, and is used to provide feed to the conveyor. The weighing unit 5 is mounted on the main frame 1 and arranged near the lower end of the conveyor, and is used to weigh the feed discharged by the feeding unit 4 and discharge it into the conveyor. During operation, feed is manually added to the feeding unit 4, which then conveys the feed to the weighing unit 5. The weighed feed falls from the weighing unit 5 into the feeding unit, and finally, the feed is transported to the rabbit cage food box by the feeding unit. The weighing unit 5 ensures that each rabbit cage food box is fed according to the set amount of feed, achieving refined feeding.

[0066] In this embodiment, the conveyor in the feeding unit can be a skirt conveyor. One or more skirt conveyors can be provided. As a preferred solution, multiple skirt conveyors are provided on the main frame 1 at the same time, so that multiple food boxes can be fed at the same time, thereby improving the feeding efficiency. Taking the example of two skirt conveyors provided on the main frame 1 at the same time, the two skirt conveyors are respectively the first skirt conveyor 2 and the second skirt conveyor 3, and the structural composition of the first skirt conveyor 2 and the second skirt conveyor 3 is the same. The following takes the first skirt conveyor 2 as an example to explain its structural composition in detail. Figure 1 and Figure 2As shown, the first skirt conveyor 2 includes a fixed frame 21, a folding frame 24, a skirt conveyor belt 26, a conveyor drive 27 and a folding mechanism, wherein the fixed frame 21 is arranged on the main frame 1 and is arranged in an up and down tilted manner, and the lower end of the fixed frame 21 is rotatably provided with a first roller 22, and the upper end of the fixed frame 21 is rotatably provided with a second roller 23 parallel to the first roller 22, and the feeding unit 4 and the weighing unit 5 are both arranged close to the first roller 22. Generally, the feeding unit 4 and the weighing unit 5 are both lower than the second roller 23, so that the structure between the feeding unit 4, the weighing unit 5 and the first skirt conveyor 2 is more compact, thereby achieving the purpose of shortening the overall height of the rabbit feeding device 100, making its center of gravity lower and not easy to tip over, and the height of the feeding unit 4 is reduced, which is more conducive to manual loading. One end of the folding frame 24 is connected to the rotating shaft of the second roller 23, and the other end is provided with a third roller 25 parallel to the first roller 22. The third roller 25 is rotatably installed on the folding frame 24, and the folding frame 24 is rotatably connected to the rotating shaft of the second roller 23 as a whole. The folding mechanism is provided on the folding frame 24, which can drive the folding frame 24 to rotate around the rotating connection point between the folding frame 24 and the rotating shaft of the second roller 23, so as to realize the folding and unfolding of the folding frame 24 relative to the fixed frame 21. The folding mechanism can also maintain the position of the folding frame 24 after the folding frame 24 is rotated to a suitable position. The folding frame 24 and the fixed frame 21 together form the overall frame of the first skirt conveyor 2. The skirt conveyor belt 26 is arranged in a closed loop outside the overall frame. The first roller 22, the second roller 23, and the third roller 25 are all in driving contact with the inner wall of the skirt conveyor belt 26. The skirt conveyor belt 26 is used to receive and convey the feed discharged by the weighing unit 5. The skirt conveyor belt 26 adopts the existing conveyor belt form with skirts and partitions. The skirt conveyor belt 26 is provided with a plurality of partitions spaced along its conveying direction. Any two adjacent partitions are closed with the skirts on both sides of the skirt conveyor belt to form a cell, and each cell is used to receive the feed discharged by the weighing unit. The above-mentioned conveyor drive 27 is connected to at least one of the first roller 22, the second roller 23, and the third roller 25 to provide conveying power for the skirt conveyor belt 26. As a preferred embodiment, the conveyor drive 27 is preferably a reduction motor, which is connected only to the first roller 22 and drives the first roller 22 to rotate, thereby driving the skirt conveyor belt 26.

[0067] In this solution, the conveying surface of the skirt conveyor belt 26 in the first skirt conveyor 2 is divided into a plurality of mutually spaced cavities by baffles, and each cavity can be used to receive the feed discharged by the weighing unit 5. This type of skirt conveyor belt 26 is a prior art and will not be described in detail here. At the same time, the folding frame 24 in the first skirt conveyor 2 is set as a foldable structure, which can adjust the conveying end of the first skirt conveyor 2 according to the size of the space in the rabbit house so as to be suitable for different spaces. It should be noted that the skirt conveyor belt 26 is generally elastic, and the change in the relative position of the folding frame 24 and the fixed frame 21 will not affect the normal use of the skirt conveyor belt 26. Accordingly, the skirt conveyor belt 26 will not hinder the folding (folding) adjustment of the folding frame 24 relative to the fixed frame 21.

[0068] Furthermore, in this embodiment, the folding mechanism specifically includes a folding motor 28 and a belt pressing device 210. The folding motor 28 can be fixed to the fixed frame 21 by bolts. The folding motor 28 is preferably a stepping motor, and its output end is connected to the folding frame 24 through a reducer, and is used to drive the folding frame 24 to rotate about the rotation connection point between the folding frame 24 and the rotating shaft of the second roller 23. The belt pressing device 210 is provided on the fixed frame 21 and is used to contact the edge of the skirt conveyor belt 26 and press the skirt conveyor belt 26 against the fixed frame 21. The belt pressing device 210 is a common component in the conveyor belt mechanism and is a prior art. Its specific structure and working principle will not be repeated here.

[0069] In this embodiment, the feeding unit further includes a storage mechanism 29, which is arranged in a one-to-one correspondence with the skirt conveyor. The structure of the corresponding storage mechanism 29 is described in detail below in conjunction with the first skirt conveyor 2. Figure 5As shown, the storage mechanism 29 includes a storage hopper 291, a first discharge device and a food box monitoring device 295. The storage hopper 291 is connected to the conveying end of the skirt conveyor belt 26, that is, the end of the folding frame 24 away from the fixed frame 21, for receiving feed from one or more cells on the skirt conveyor belt 26; the first discharge device specifically includes a first cover plate 293 and a first flip mechanism 294. The first cover plate 293 is rotatably set at the bottom opening of the storage hopper 291 through a first rotating pin 292. The first flip mechanism 294 is set on the storage hopper 291 and is used to drive the first cover plate 293 to switch between an open state and a closed state. In the closed state, the first cover plate 293 blocks the bottom opening of the storage hopper 291, and the feed is stored in the storage hopper 291. In the open state, the bottom opening of the storage hopper 291 is opened, and the feed stored in the storage hopper 291 is discharged into the food box of the rabbit cage. Generally, the first flip mechanism 294 can be a telescopic member such as a hydraulic cylinder or an electric telescopic rod. For example, the electric telescopic rod can be directly mounted on the side wall of the hopper 291, and its telescopic motion drives the first cover 293 to open and close about the first rotating pin 292. The food box monitoring device 295 is mounted on the hopper 291 and is in communication with the first flip mechanism. When the food box monitoring device 295 detects a rabbit cage food box to be fed, it triggers the first flip mechanism to switch the first cover 293 to the open state.

[0070] Furthermore, the above-mentioned food box monitoring device 295 serves as an identification and positioning unit, which can be an infrared detection device or an image acquisition device. For example, if the food box monitoring device 295 is an image acquisition device, Figure 5 As shown, it specifically includes a camera 2951, a camera bracket 2952 and a support 2953. The support 2953 can be set on the same side of the storage hopper 291 as the electric telescopic rod. The camera bracket 2952 is connected to the support 2953, and the camera 2951 is set on the camera bracket 2952. The camera 2951 can monitor in real time whether the storage hopper 291 reaches the top of the rabbit cage food box. When the camera 2951 detects the rabbit cage food box within the visual range, it means that the storage hopper 291 is already above the rabbit cage food box. At this time, the electric telescopic rod can receive the signal and open the first cover 293 to discharge the feed stored in the storage hopper 291 into the corresponding rabbit cage food box. When the storage mechanism 29 is working, the feed for one feeding amount falls from the first skirt conveyor 2 or the second skirt conveyor 3 into the corresponding storage hopper 291 for temporary storage. When the camera 2951 is positioned at the position of the rabbit cage food box, the first flip mechanism 294 (electric telescopic rod) starts to work, which is specifically manifested in that the electric telescopic rod contracts and pulls the first cover plate 293 to rotate around the first rotating pin 292, opening the closed first cover plate 293, and the feed falls from the bottom opening of the storage hopper 291 into the corresponding rabbit cage food box below, completing the feeding work.

[0071] In this embodiment, Figure 3 As shown, the feeding unit 4 includes a cylindrical closed shell 41, a conveying auger 44, a silo 45 and an auger drive. The silo 45 is arranged on the main frame 1, and the cylindrical closed shell 41 is fixed to the bottom of the silo 45 through a frame 46. The cylindrical closed shell 41 is generally placed horizontally, and a feed port 42 is provided above one axial end of the cylindrical closed shell 41. The feed port 42 is connected to the bottom outlet of the silo 45. A discharge port 43 is provided below the other axial end of the cylindrical closed shell 41. The discharge port 43 is located above the feed port of the weighing unit 5. The silo 45 is used to feed the feed port 41 to the weighing unit 5. 2. Feeding: A conveying auger 44 is disposed within the cylindrical enclosed housing 41 and coaxially arranged therewith. Its two ends are connected to the ends of the cylindrical enclosed housing 41 via bearings. The conveying auger 44 is used to transport feed within the cylindrical enclosed housing 41 to the discharge port 43. The auger drive is used to rotate the conveying auger 44. The auger drive generally includes a stepper motor 47, a reducer 48, and a coupling 49. The output end of the stepper motor 47 is connected to the reducer 48, and the output end of the reducer 48 is connected to the rotation of the conveying auger 44 via the coupling 49. The conveying auger 44 is a conventional mechanism and will not be described in detail here. In operation, feed enters the feed port 42 of the feeding unit 4 from the hopper 45. The stepper motor 47 drives the conveying auger 44 to rotate within the cylindrical enclosed housing 41, transporting the feed within the cylindrical enclosed housing 41 from the feed port 42 to the discharge port 43.

[0072] In this embodiment, Figure 4 As shown, the weighing unit 5 includes a weighing hopper 51, a second discharge device and a weighing sensor 55. The weighing hopper 51 is suspended on the main frame 1 and is located between the discharge port 43 and the lower end of the skirt conveyor belt 26; the second discharge device includes a second cover plate 52 and a second flip mechanism 54. The second cover plate 52 is rotatably arranged at the bottom opening of the weighing hopper 51 through a second rotating pin 53. The second flip mechanism 54 is arranged on the weighing hopper 51 and is used to drive the second cover plate 52 to open and close. The weighing hopper 51 is switched between closed and open states, wherein, in the closed state, the second cover plate 52 blocks the bottom opening of the weighing hopper 51, and in the open state, the bottom opening of the weighing hopper 51 is opened, and the feed in the weighing hopper 51 is discharged into the cell cavity on the skirt conveyor belt 26; the weighing sensor 55 is arranged on the weighing hopper 51 and is in communication connection with the second flip cover mechanism 54, so that when the feed in the weighing hopper 51 meets the set weight, the second flip cover mechanism 54 is triggered to switch the second cover plate 52 to the open state. The above-mentioned weighing hopper 51 is provided with a support plate 56 near its top, and support plates 56 are provided on both the left and right sides of the weighing hopper 51. The weighing hopper 51 can be fixed on the main frame 1 under the action of the two support plates 56, as shown in FIG. Figure 4As shown, each support plate 56 is provided with a weighing sensor 55. The second flip cover mechanism 54 can adopt telescopic parts such as hydraulic cylinders and electric telescopic rods. Taking the electric telescopic rod as an example, the electric telescopic rod can be directly set on the side wall of the weighing hopper 51, and the second cover plate 52 is driven to open and close around the second rotating pin 53 through telescopic movement. In specific operation, the feed falls into the weighing hopper 51 from the discharge port 43, and the weighing sensor 55 works. When the weight of the feed falling into the weighing hopper 51 reaches the set threshold, the electric telescopic rod (here the electric telescopic rod is the second flip cover mechanism 54) starts to work, and the electric telescopic rod contracts to pull the second cover plate 52 to rotate around the second rotating pin 53, opening the closed second cover plate 52, and the feed falls from the bottom opening of the weighing hopper 51 onto the corresponding first skirt conveyor 2 or second skirt conveyor 3 below, completing the feed weighing work.

[0073] In the feeding unit of this embodiment, each skirt conveyor is equipped with a storage mechanism 29, a feeding unit 4 and a weighing unit 5. Figure 1 and Figure 2 As shown, the bottom of the first skirt conveyor 2 is connected to the main frame 1 via a bracket 211; correspondingly, the bottom of the second skirt conveyor 3 is also connected to the main frame 1 via a bracket. The bracket 211 at the bottom of the first skirt conveyor 2 and the bracket at the bottom of the second skirt conveyor 3 are preferably aluminum profile brackets.

[0074] In this embodiment, the first skirt conveyor 2 and the second skirt conveyor 3 are preferably arranged side by side along the arrangement direction of the rabbit cage food boxes, wherein the setting height of the second roller 23 in the first skirt conveyor 2 is higher than the setting height of the second roller in the second skirt conveyor 3, so that the conveying ends of the two skirt conveyors correspond to rabbit cage food boxes of different heights, such as Figure 1 and Figure 6 As shown, the second roller 23 of the first skirt conveyor 2 is set at a higher height, and accordingly, the folding frame 24 on it is positioned higher, allowing feed to be delivered to the food boxes in the upper row, namely, the upper rabbit cage food boxes 200. The second roller of the second skirt conveyor 3 is set at a lower height, and accordingly, the folding frame on it is positioned lower than the folding frame 24, allowing feed to be delivered to the food boxes in the lower row, namely, the lower rabbit cage food boxes 300. During operation, feed falls from the weighing hopper 51 into the cells of the first skirt conveyor 2 or the second skirt conveyor 3 for temporary storage. A single feeding amount of feed is then stored in the storage hopper 291 at the end of the first skirt conveyor 2 or the second skirt conveyor 3. As the rabbit feeding device 100 moves to the next rabbit cage food box to be fed, the feed can be continuously weighed as it moves. When the rabbit feeding device 100 locates the position of the rabbit cage food box using the camera 2951, the feed stored in the storage hopper 291 accurately falls into the rabbit cage food box.

[0075] This embodiment also includes a mobile device 6 disposed at the bottom of the main frame 1. The mobile device 6 may include multiple sets of wheels or may be an automated guided vehicle. Preferably, the mobile device 6 is an automated guided vehicle, which is used to navigate the entire rabbit feeding device 100, generally moving the rabbit feeding device 100 along the direction in which the food boxes are arranged in the rabbit cage.

[0076] In this embodiment, the above-mentioned feeding unit 4 adds CAN bus communication, and the weighing unit uses RS485 communication, which is used to control the opening and closing and speed of the motors in the feeding unit 4 and the weighing unit 5 in real time, so that the feeding and weighing efficiency is higher, the breakage rate is lower, and the control is more precise; the weighing unit 5 uses weighing feedback and PID controller real-time calculation to achieve closed-loop control, thereby improving the control accuracy of the system.

[0077] The specific working process and working principle of the rabbit feeding device 100 are as follows:

[0078] During the feeding process, the operator places an appropriate amount of feed into the silo 45 for storage, and then transports the feed in the silo 45 to the weighing hopper 51 for weighing through the feeding unit 4. After reaching the threshold, the second cover 52 opens and discharges the feed into the corresponding empty cavities on the skirt conveyor belt 26 (all the cavities transmitted from the storage hopper 291 to the weighing hopper 51 are empty cavities). After the feed is discharged, the second cover 52 returns to the closed state, and the weighing hopper 51 continues to weigh the feed from the feeding unit 4. When the second cover 52 needs to be opened, the skirt conveyor belt can be stopped, that is, when the feed in the weighing hopper 51 meets the set feeding weight (i.e., the threshold), the control system will trigger the skirt conveyor belt to stop running. At this time, the weighing hopper 51 is directly below an empty cavity, and the control system will trigger the second flip mechanism to open the second cover 52 to discharge the feed into the empty cavity; after the feed in the weighing hopper 51 is emptied, the control system will trigger the skirt conveyor belt to continue running, and trigger the second flip mechanism to close the second cover 52 to continue the weighing operation. In addition, when the second cover 52 needs to be opened, the skirt conveyor belt can also not stop, but maintain low speed operation. Its running speed can ensure that the feed in the weighing hopper 51 can be completely discharged into the same cell from the opening of the second cover 52 to the closing of the second cover 52. The running speed of the skirt conveyor belt can be adaptively adjusted according to factors such as the cell width and the volume of feed in the weighing hopper 51. In addition, it should be noted that the volume of each cavity on the skirt conveyor belt is the same, and the above-mentioned "threshold" corresponds to the volume of each cavity. Generally, the feed that meets the "threshold" will just fill up one cavity.

[0079] During the storage process, the skirt conveyor transports the feed in the cells to the storage hopper 291 for temporary storage. Accordingly, the volume of the storage hopper 291 is no less than that of one cell, and the storage hopper 291 can simultaneously store feed from multiple cells. To achieve precise control and efficient feeding, it is preferred that the storage hopper 291 only receive and hold feed from one cell at a time. After the storage hopper 291 empties the feed, it can receive feed from the next cell. It should be noted that during this storage process, the skirt conveyor continues to transport feed, and the aforementioned feeding phase also circulates. That is, the feeding unit 4 continues to supply feed to the weighing hopper 51 of the weighing unit, and the weighing unit continues to weigh the feed. After reaching a threshold, the feed is discharged into the corresponding cell on the skirt conveyor belt so that after the storage hopper 291 empties, it can promptly receive feed from the next cell. Each stage is closely connected, and each component unit cooperates and coordinates, thereby achieving a continuous cycle of feeding, weighing, and storage.

[0080] Next comes the transfer and feeding process. When the camera 2951 detects that the hopper 291 has reached the top of the rabbit cage food box to be fed, the electric telescopic rod on the hopper 291 retracts, pulling the first cover plate 293 along the first rotating pin 292, opening the bottom opening of the hopper 291. The feed falls from the hopper 291 into the rabbit cage food box below, completing a feeding operation. The moment feeding is completed, the first cover plate 293 resets and blocks the bottom opening of the hopper 291, allowing the hopper 291 to promptly receive the feed from the next cell. At the same time, the automatic guided vehicle drives the rabbit feeding device 100 along the layout direction of the rabbit cage food box to move the rabbit feeding device 100 to the next rabbit cage food box to be fed, so as to feed the next rabbit cage food box. Generally, while the weighing hopper 51 is weighing the feed, the skirt conveyor moves forward one cell, simultaneously feeding the feed from the frontmost cell into the hopper.

[0081] During the movement of the rabbit feeding device 100, the above-mentioned feeding process and storage process are carried out simultaneously, that is, during each movement of the rabbit feeding device 100 from one rabbit cage food box to the next rabbit cage food box, the rabbit feeding device 100 still performs feeding (weighing), dropping, delivering (the conveyor receives and delivers feed) and storing material in the storage hopper until it reaches the corresponding food box and discharges the feed in the storage hopper. The rabbit feeding device 100 of this solution realizes walking, weighing and delivering feed, which effectively improves the feeding efficiency of the rabbit cage.

[0082] When a row of rabbit cages 400 is fed, the rabbit feeding device 100 needs to turn at the aisle 500 at the end of the rabbit cages 400, that is, the turning stage. Due to the narrow aisle 500, the folding frame of the skirt conveyor can only be folded and contracted before turning. After the folding frame of the skirt conveyor is folded, the rabbit feeding device 100 completes the turning at the aisle 500, and then repeats the above-mentioned feeding process, storage process, transportation and feeding process, and performs subsequent feeding until all rabbit cage food boxes are fed. Figure 4 The direction of the middle tip is a walking direction of the rabbit feeding device 100 in the rabbit house.

[0083] As can be seen from the above, the rabbit feeding device 100 proposed in this technical solution has a compact structure, a high degree of automation, reliable performance, and fully meets the actual production needs. It can reduce the workload of workers, improve labor efficiency, and improve feeding accuracy, which is beneficial to the development of the rabbit breeding industry. The specific beneficial effects are as follows:

[0084] (1) A skirt conveyor belt is used to lift the feed from the bottom to the position of the rabbit cage food box. The height of the lower part of the silo, the weighing hopper 51 and the feeding unit 4 are all lower than the height of the rabbit cage food box, thereby reducing the overall height of the feeding device. This can reduce the difficulty of workers loading the feed and the center of gravity of the rabbit feeding device, solving the problems of the feeding device being too high, which makes it difficult for workers to load the feed, and the device being prone to tipping over due to a high center of gravity.

[0085] (2) The feed stored in the feed bin is transported to the weighing hopper below the feeding unit through the feeding unit, and the feed is accurately weighed, which can ensure that the weight of feed fed to each rabbit, that is, each rabbit cage food box, is the same, thereby ensuring the accuracy of feeding, reducing manual participation, and improving the efficiency of feeding rabbits.

[0086] (3) The feeding unit uses a skirt conveyor to transport feed, and a storage hopper is added at the end of the skirt conveyor for leaking feed. The rabbit feeding device 100 can be moved while the skirt conveyor is driven, and the weighing hopper is weighing at the same time. The weighed feed can be temporarily stored in the cell cavity of the skirt conveyor belt to achieve continuous weighing, thereby effectively shortening the feeding time of the rabbits, ensuring the feeding accuracy and improving the feeding efficiency.

[0087] (IV) In this solution, the feeding unit, the supply unit and the weighing unit work together and connect the operations to realize the periodic cycle automation operation of feeding, weighing, transporting, storing and dropping, which effectively improves the feeding efficiency.
