Description

Technical Field

[0001] The present invention relates to the technical field of livestock breeding, and specifically to an automatic feed supplement and feeding device. Background Art

[0002] Livestock breeding refers to the production department that raises livestock and poultry in ways such as grazing, penning, or a combination of both to obtain animal products or draft animals. It includes the raising of domestic animals and poultry and the domestication of wild animals. Domestic animals include pigs, cows, sheep, horses, camels, rabbits, cats, dogs, etc., and poultry includes chickens, ducks, geese, turkeys, pigeons, domesticated quails, etc.

[0003] In traditional livestock breeding, feed feeding is generally carried out manually. The manual feeding method not only consumes time and effort, but also is difficult to achieve precise feeding, easily causing feed waste or nutritional imbalance. Most common automatic feed feeding devices on the market adopt a single silo design, and the feed is conveyed to the feed trough through a screw conveyor or a belt conveyor. Although such devices achieve basic automation, it is difficult to provide layered and classified feeding for livestock and poultry at different growth stages, resulting in low feed utilization rate. Moreover, they lack a dynamic weighing system and cannot monitor the feeding amount in real time, easily causing feed waste or insufficient supply. For this reason, we propose an automatic feed supplement and feeding device. Summary of the Invention

Through the transmission connection between the first pulley 25 and the second pulley 26, and the transmission connection between the third pulley 27 and the fourth pulley 28, the feed stirring shafts 12 in the three feed storage boxes 8 rotate simultaneously, and cooperate with the multiple stirring blades 13 on the outside of the feed stirring shaft 12 to efficiently stir the feed inside the feed storage box 8.

[0028] One end of the feed stirring shaft 12 located outside the feed storage box 8 is connected with a rotary joint 29. A hot air blower 30 is fixedly installed at the top of the support base 1, and the air outlet end of the hot air blower 30 is fixedly connected with a ventilation pipe 31. The end of the ventilation pipe 31 forms three branch pipes, and the three branch pipes are respectively connected with the three rotary joints 29. The outer side of the feed stirring shaft 12 is equidistantly provided with hot air outlets 15.

[0029] A vertically oriented communication port 22 is provided at the top of the fixed plate 18. The feed supplement cylinder 23 passes through the communication port 22. Electric control valves 7 are installed on the outer sides of the feeding cylinder 6 and the feed supplement cylinder 23. The setting of the electric control valve 7 can control the on-off of the feeding cylinder 6 and the feed supplement cylinder 23. The bottom end inside the feed weighing cylinder 20 is of a hollow hemispherical structure.

[0030] The bottom end inside the feed weighing cylinder 20 is of a hemispherical structure, and the feed supplement cylinder 23 is arranged at the central position of the bottom of the feed weighing cylinder 20. When the electric control valve 7 on the outer side of the feed supplement cylinder 23 is opened, the feed inside the feed weighing cylinder 20 can be quickly and completely discharged, avoiding the accumulation of the internal feed.

[0031] One side of the support base 1 is provided with a slider that mates with the slide rail at the bottom end of the livestock cage. The support base 1 is slidably connected to the surface of the slide rail. A slide rail is provided at the bottom end of the livestock cage, and the support base 1 is slidably arranged on the slide rail. By controlling the movement on the slide rail through the provided power system control device, the device can be moved along the livestock cage. After the device is installed on the slide rail, each feed supplement cylinder 23 is respectively located above each layer of the feed trough, facilitating the feeding of the feed.

[0032] A storage drawer 32 is provided on the side wall of the support base 1. Handles are provided on the surfaces of the first connection cover 9 and the storage drawer 32.

[0033] When the present invention is in use, the device is provided with a controller for control. The device adopts a three-layer feed storage box 8, and the three-layer feed storage boxes 8 are fixedly connected, which can store feeds of different types or stages to meet the differentiated feeding requirements. Moreover, the top-layer feed feeding mechanism 2, the middle-layer feed feeding mechanism 3, and the bottom-layer feed feeding mechanism 4 can be used to feed the troughs of the middle-layer and high-layer chicken coops, achieving the purpose of supplementing the feeds of multiple troughs at one time. By controlling the driving motor 35 to work through the controller set in the device, the driving gear 34 is driven to rotate. Through the meshing connection of the driving gear 34 and the driving motor 35, the feed stirring shaft 12 in the top-layer feed storage box 8 rotates. Through the transmission connection of the first belt pulley 25 and the second belt pulley 26, and the transmission of the third belt pulley 27 and the fourth belt pulley 28, the feed stirring shafts 12 in the three feed storage boxes 8 rotate simultaneously. With the cooperation of the stirring blades 13, the feeds in the feed storage boxes 8 are stirred to prevent the feeds from caking. At the same time, the hot air blower 30 works to make hot air enter the feed storage box 8, which can heat the feeds in the feed storage box 8 to prevent the feeds from being too cold and causing harm to animals. When the materials in the feed storage box 8 are insufficient, feeding is carried out through the screw feeder 5. By controlling the rotation motor 16 on the top-layer feed feeding mechanism 2, the middle-layer feed feeding mechanism 3, or the bottom-layer feed feeding mechanism 4 to work, the screw conveyor 14 inside the feed delivery pipe 11 can be driven to rotate, and the feed is conveyed to the discharge cylinder 17 and placed in the feed weighing cylinder 20. When the materials in the feed weighing cylinder 20 reach the weight set by the weighing sensor 21, the weighing sensor 21 detects the signal and transmits the signal to the controller. The controller controls the rotation motor 16 to stop working. At the same time, the electric control valve 7 on the feed supplement cylinder 23 is opened, so that the feeds inside the feed weighing cylinder 20 on the top-layer feed feeding mechanism 2, the middle-layer feed feeding mechanism 3, or the bottom-layer feed feeding mechanism 4 are put into the trough. The hot air blower 30 works to make hot air enter the feed storage box 8, which can heat the feeds in the feed storage box 8 to prevent the feeds from being too cold and causing harm to animals. The hot air blower 30 can adjust the temperature of the incoming air and can also heat-dry the feeds to avoid feed caking. In short, the present invention can store feeds of different types or stages at the same time, and achieve precise quantitative feeding through the weighing sensor and the electric control valve, having the advantages of effectively avoiding feed waste, improving the feeding efficiency, the feeding mechanisms of each layer can be independently controlled, and strong practicability.
