Description

Technical Field

[0001] This utility model belongs to the technical field of livestock breeding equipment, and more specifically, it relates to a circulating feeding device for livestock feeding. Background Technology

[0002] Currently, there are two main types of feeding methods in livestock farms. One is purely manual feeding, where farmers need to move feed to the trough multiple times a day. This is time-consuming, labor-intensive, and the accuracy of manual feeding is poor, which can easily lead to uneven feeding of livestock and affect their growth rate.

[0003] Another type is automatic feeding equipment. For example, patent publication number "CN215836467U" discloses a circulating feeding structure for animal husbandry and veterinary medicine. This structure includes a feeding pipe with several uniformly arrayed discharge pipes connected to its bottom. A U-shaped plate (three sets in total) is fitted around the outside of the feeding pipe. A discharge pipe is fixedly installed in the middle of the bottom wall of the U-shaped plate. A movable rod passes through the middle of the top wall of the U-shaped plate, and an arc-shaped plate is fixedly installed at the bottom end of the movable rod, locking onto the feeding pipe. A spring is fitted onto the upper side of the movable rod near the arc-shaped plate. A flow-limiting cylinder is fitted around the bottom outside of the discharge pipe, and a protrusion is fixedly installed on the right side of the flow-limiting cylinder. This feeding structure, with its U-shaped plate, arc-shaped plate, and discharge pipe, allows for adjustable discharge pipe positions. The position of the discharge pipe can be selectively adjusted according to the array position of the feed trough, making it highly versatile and suitable for widespread promotion and use.

[0004] However, the above solution still has the following problems: 1. The discharge pipe is a uniform array, which limits the adjustment range of the discharge pipe. The adjustment capability is limited by the spacing of the discharge pipe array and the number of U-shaped plates. Moreover, the adjustment spacing is fixed by the discharge pipe and cannot be adapted to complex feed trough layouts. 2. The structure is not stable enough. The spring is the core force source for the arc plate to stick to the feed pipe. However, feed dust and moisture in the livestock farm environment can accelerate the fatigue of the spring. After long-term use, the elasticity will decrease, which will lead to insufficient clamping force of the arc plate on the feed pipe. In addition, if the material impacts or the equipment vibrates slightly during feeding, the U-shaped plate and the feed pipe are prone to displacement, causing the feed pipe and the discharge pipe to deviate from the alignment, resulting in leakage and misalignment of the feed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a circulating feeding device for livestock. It uses a "longitudinal and transverse frame" composed of longitudinal beams and transverse beams, combined with longitudinal and transverse sliding mechanisms, to allow the feeding bin to move arbitrarily in the plane. With the height adjustment of the lifting mechanism, it can cover feed troughs of different positions, heights and shapes, and adapt to the complex layout of large-scale farms.

[0006] The aforementioned livestock feeding recirculating feeding device includes at least two parallel longitudinal beams. The bottom of the longitudinal beams is fixedly connected to a plurality of equally spaced support columns. At least one crossbeam is slidably connected to the opposite side of adjacent longitudinal beams. The crossbeam is perpendicular to the longitudinal beams.

The bottom of the lifting mechanism is fixedly connected to a feeding bin. The bottom of the feeding bin is connected to a discharging mechanism. A rotating impeller is rotatably connected inside the discharging mechanism. The bottom of the discharging mechanism is fixedly connected to a flexible discharge pipe.

[0007] Preferably, upper and lower guide rails are fixedly connected to the opposite side of the adjacent longitudinal beams and the two sides of the crossbeams, respectively. The upper and lower guide rails are arranged in parallel, and both the upper part of the upper guide rail and the lower part of the lower guide rail are provided with rails. The rails extend beyond the corresponding end faces of the longitudinal beams and crossbeams, and the bottom of the upper guide rail is provided with a rack.

[0008] Preferably, both ends of the crossbeam are slidably connected to the longitudinal beam via a longitudinal sliding mechanism. The longitudinal sliding mechanism includes a sliding plate. On the side of the sliding plate near the longitudinal beam, a plurality of longitudinal rollers are rotatably connected to the tracks of the upper guide rail and the lower guide rail, respectively. On the side of the sliding plate away from the longitudinal beam, a longitudinal drive motor is fixedly connected. The power output end of the longitudinal drive motor is connected to a gearbox, and the power output end of the gearbox is connected to a drive gear, which meshes with a rack.

[0009] Preferably, a driven gear is rotatably connected to the end of the sliding plate away from the driving gear, and the driven gear meshes with the rack.

[0010] Preferably, a transverse sliding mechanism is slidably connected to the crossbeam. The transverse sliding mechanism includes a sliding frame. Multiple transverse rollers that respectively cooperate with the tracks of the upper guide rail and the lower guide rail are rotatably connected to the two side walls inside the sliding frame. A transverse drive motor is fixedly connected to the outside of the sliding frame. A drive gear and a driven gear that cooperate with the corresponding rack are rotatably connected inside the sliding frame. A transverse drive motor is fixedly connected to the outside of the sliding frame. The transverse drive motor drives the corresponding drive gear to rotate.

[0011] Preferably, the sliding frame has a four-frame structure and is fitted onto the outside of the crossbeam.

[0012] Preferably, the lifting mechanism includes a protective shell, which is fixedly connected to the bottom of the sliding frame. Two sets of rope reels are rotatably connected inside the protective shell. A lifting reduction motor for driving the rope reels to rotate is fixedly connected to the protective shell. Steel wire ropes are provided on both sets of rope reels, and fixed frames are rotatably connected to the steel wire ropes through movable pulleys.

[0013] Preferably, the top of the feeding hopper is fixedly connected to a hopper cover, the bottom of the feeding hopper is provided with a funnel-shaped discharge port, multiple reinforcing ribs are fixedly connected between the hopper cover and the feeding hopper, and a feeding port is provided on one side of the feeding hopper, with a sealing cap rotatably connected to the feeding port.

[0014] Preferably, the feeding mechanism includes a feeding storage bin, which is sealed and fixedly connected to the discharge port. A rotating impeller is rotatably connected inside the feeding storage bin, and a feeding motor for driving the rotating impeller is fixedly connected to the feeding storage bin.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a "longitudinal and transverse frame" composed of longitudinal and transverse beams, combined with longitudinal and transverse sliding mechanisms, to allow the feeding bin to move arbitrarily in the plane. With the height adjustment of the lifting mechanism, it can cover feed troughs of different positions, heights and shapes, and adapt to the complex layout of large-scale farms.

[0016] 2. The rotating impeller in the feeding mechanism achieves quantitative feeding through the blade cavity. Combined with the speed control of the feeding motor, the feeding amount can be precisely adjusted, such as setting the feeding amount according to the growth stage of livestock. The flexible discharge pipe can achieve feeding close to the feed trough, reducing the spillage and dust during the feed falling process. Compared with traditional manual feeding or fixed pipeline feeding, it can reduce feed waste by 15%-30%.

[0017] 3. The design adopts a double guide rail system with multiple rollers to convert sliding friction into rolling friction, reducing component wear; both the drive gear and the driven gear mesh with the rack to ensure smooth transmission and avoid jamming or deviation; automatic positioning, lifting, and feeding are achieved through motor drive, eliminating the need for manual feeding in each trough, which is especially suitable for large-scale farms and avoids the time difference of manual feeding.

[0020] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] like Figures 1 to 9 As shown, a circulating feeding device for livestock includes at least two parallel longitudinal beams 11. The number of longitudinal beams 11 can be arranged according to the structure and size of the farm. The longitudinal beams 11 serve as the main longitudinal support frame. Their parallel arrangement ensures the straightness and stability of the subsequent sliding of the crossbeams 12, provides longitudinal structural rigidity for the entire device, bears the weight of components such as the crossbeams 12 and the feeding bins 4, and limits the longitudinal coverage area of ​​the device. Multiple equally spaced support columns 1 are fixedly connected to the bottom of the longitudinal beams 11. During installation, the support columns 1 are fixed to the ground using anchor bolts. The support columns 1 raise the longitudinal beams 11 to a suitable height, facilitating subsequent circulating feeding. Furthermore, the support columns 1 ensure even stress distribution on the longitudinal beams 11, preventing excessive local loads that could lead to deformation and ensuring the overall stability of the device.

[0022] At least one crossbeam 12 is slidably connected to the opposite side of each adjacent longitudinal beam 11. The number of crossbeams 12 can be rationally planned according to the growth and development status of livestock, facilitating the feeding of different feeds to livestock at different growth stages. The crossbeams 12 are perpendicular to the longitudinal beams 11. This vertical setting enhances the overall structural strength of the device while facilitating the subsequent feeding components to cover different positions of the feed troughs, thus expanding the feeding coverage area. One or more transverse sliding mechanisms 2 are slidably connected to the crossbeams 12. The transverse sliding mechanisms 2 serve as the transverse movement execution structure of the feeding components. Combined with the longitudinal movement of the crossbeams, they enable the flexible movement of the feeding bin 4, allowing for precise alignment with feed troughs of different positions and shapes, meeting the feeding needs of multiple feed troughs and irregularly shaped feed troughs.

[0023] A lifting mechanism 3 is fixedly connected to the bottom of the lateral sliding mechanism 2. The lifting mechanism 3 can change the height of the feeding bin from the ground through extension or retraction. On the one hand, it can adapt to feed troughs of different heights (such as low piglet feed troughs and higher fattening pig feed troughs). On the other hand, it can raise the feeding bin 4 during movement to avoid collisions with ground obstacles or livestock. The lifting mechanism also facilitates feeding into the feeding bin 4. The bottom of the lifting mechanism 3 is fixedly connected to the feeding bin 4, which is a feed storage and temporary storage container used to load feed to be fed. Its volume can be designed according to the amount of feed to be fed at one time, ensuring continuous feeding without frequent refilling. At the same time, as an intermediate component connecting the lifting mechanism 3 and the discharging mechanism 5, it can stably transport feed to the discharging mechanism 5. The bottom of the feeding bin 4 is connected to the discharging mechanism 5. A rotating impeller 502 is rotatably connected inside the discharging mechanism 5. The discharging mechanism 5 controls the feeding, stopping, and feeding speed of the feed through the rotating impeller 502, avoiding large amounts of feed spillage at once and achieving quantitative and uniform feeding. The bottom of the feeding mechanism 5 is fixedly connected to a flexible discharge pipe 6. The flexible material can adapt to the slight positional deviation of the feed trough, eliminating the need for precise alignment and preventing damage caused by the hard pipe colliding with the feed trough. At the same time, it is convenient to feed closer to the feed trough opening, reducing spillage and dust during the feed falling process, and also preventing livestock from directly contacting the feeding mechanism 5 and causing damage to the components.

[0024] Specifically, such as 3 and Figure 4 As shown, upper guide rails 1101 and lower guide rails 1104 are fixedly connected to the opposite side of the adjacent longitudinal beams 11 and the two sides of the crossbeams 12, respectively. Both upper guide rails 1101 and lower guide rails 1104 are guide rails for sliding components. The upper and lower double guide rail design can limit the sliding direction and prevent tilting and jamming during sliding; at the same time, it provides a stable support surface for the sliding components, disperses the friction force during sliding, and extends the service life of the components.

[0025] The upper guide rail 1101 and the lower guide rail 1104 are set parallel to each other to ensure that the sliding component moves in a straight line and avoids deviation. Both the upper guide rail 1101 and the lower guide rail 1104 are equipped with rails 1102, which cooperate with rollers to convert sliding friction into rolling friction, significantly reducing sliding resistance and making the subsequent movement of the crossbeam 12 and the transverse sliding mechanism 2 smoother, reducing the motor load. During installation, the rails 1102 extend beyond the corresponding upper and lower end faces of the longitudinal beam 11 and the crossbeam 12 to prevent the rollers from rubbing or colliding with the longitudinal beam 11 or the crossbeam 12, ensuring stable operation of the sliding component throughout its entire stroke. The bottom of the upper guide rail 1101 is equipped with a rack 1103, which meshes with the gears of the sliding component to convert the rotational motion of the drive motor into the linear motion of the sliding component. The rack 1103 features high transmission accuracy and strong load capacity, making it more suitable for heavy-duty sliding scenarios involving feed in livestock farms.

[0026] Both ends of the crossbeam 12 are slidably connected to the longitudinal beam 11 via a longitudinal sliding mechanism 13. The longitudinal sliding mechanism 13 provides power for the longitudinal movement of the crossbeam, ensuring that the crossbeam 12 can move stably and accurately along the longitudinal beam. The longitudinal sliding mechanism 13 includes a sliding plate 1301, which is the main mounting frame of the longitudinal sliding mechanism 13. Specifically, on the side of the sliding plate 1301 near the longitudinal beam 11, multiple longitudinal rollers 1305 are rotatably connected to the tracks 1102 of the upper guide rail 1101 and the lower guide rail 1104, respectively. The longitudinal rollers 1305 are friction conversion components for longitudinal sliding. They roll in cooperation with the tracks 1102, changing the sliding friction between the sliding plate 1301 and the guide rail into rolling friction, reducing resistance. The multiple rollers also ensure that the sliding plate 1301 is evenly stressed, preventing unilateral tilting and ensuring smooth longitudinal sliding of the crossbeam.

[0027] A longitudinal drive motor 1302 is fixedly connected to the side of the sliding plate 1301 away from the longitudinal beam 11. A gearbox 1303 is connected to the power output end of the longitudinal drive motor 1302. The gearbox 1303 reduces the motor's output speed through gear reduction, ensuring a smooth sliding speed for the crossbeam; it also increases the output torque through speed reduction, ensuring the crossbeam 12 can still slide normally while bearing the weight of the feeding bin 4 and the feed. A drive gear 1304 is connected to the power output end of the gearbox 1303, meshing with a rack 1103. Starting the longitudinal drive motor 1302 converts the rotational motion output from the gearbox 1303 into linear motion of the sliding plate 1301, thereby driving the crossbeam 12 to slide along the guide rail of the longitudinal beam 11.

[0028] In this embodiment, a mounting groove 204 is provided at the end of the sliding plate 1301 away from the driving gear 1304. A mounting block is fixed in the mounting groove 204, and a driven gear 1306 is rotatably connected to the mounting block. The driven gear 1306 meshes with the rack 1103. The mounting groove 204 facilitates the installation of the driven gear 1306. The driven gear 1306 meshes with the rack 1103, forming a symmetrical force-bearing structure with the driving gear 1304. This makes the force on the sliding plate 1301 on the rack 1103 more balanced, avoiding tilting, jamming, or skipping of the sliding plate 1301. At the same time, it enhances the transmission stability, reduces the wear of the gears and rack, and extends the life of the transmission components.

[0029] A transverse sliding mechanism 2 is slidably connected to the crossbeam 12. The transverse sliding mechanism 2 includes a sliding frame 201, which has a four-frame structure, improving its stability. The sliding frame 201 is fitted onto the outside of the crossbeam 12, making the connection between the sliding frame 201 and the crossbeam 12 tighter and preventing swaying during transverse movement. At the same time, the four-frame structure has high rigidity and can bear the weight of the lifting mechanism 3 and the feeding bin 4, preventing deformation of the sliding frame 201. Multiple transverse rollers 202 are rotatably connected to the two inner side walls of the sliding frame 201, which respectively cooperate with the tracks 1102 of the upper guide rail 1101 and the lower guide rail 1104. A transverse drive motor 203 is fixedly connected to the outer side of the sliding frame 201. A drive gear 1304 and a driven gear 1306 that cooperate with the corresponding rack 1103 are rotatably connected inside the sliding frame 201. The transverse drive motor 203 is fixedly connected to the outer side of the sliding frame 201, and drives the corresponding drive gear 1304 to rotate. This structure is based on the same principle as the longitudinal sliding mechanism 13, and will not be described in detail here.

[0030] like Figure 5 and Figure 6 As shown, the lifting mechanism 3 includes a protective shell 301, which is fixedly connected to the bottom of the sliding frame 201. The protective shell 301 protects internal components such as the rope reel 306, wire rope 305, and motor from feed dust contamination. Furthermore, by being fixed to the sliding frame 201, the lifting mechanism 3 moves synchronously with the lateral sliding mechanism 2, ensuring coordinated feeding position and lifting action. Two sets of rope reels 306 are rotatably connected inside the protective shell 301. The rope reels 306 are the winding and unwinding components of the wire rope 305, achieving winding and unwinding of the wire rope 305 through forward and reverse rotation, thereby driving the feeding bin 4 to rise and fall. Each rope reel 306 is equipped with a limiting rod 308 fixedly connected to the protective shell 301. The limiting rod 308 restricts the proper winding of the wire rope 305, preventing tangled winding.

[0031] In this embodiment, two sets of rope reels 306 are symmetrically arranged to ensure more even force distribution on the wire rope 305, preventing tilting of the feeding hopper 4 during lifting and lowering, and avoiding feed spillage or structural damage. A lifting reduction motor 302 for driving the rotation of the rope reels 306 is fixedly connected to the protective shell 301. The forward and reverse rotation of the lifting reduction motor 302 controls the winding and unwinding of the wire rope 305 on the rope reels 306, thus achieving the raising and lowering of the feeding hopper 4. During installation, the two sets of rope reels 306 share a common wire rope 305. A fixed frame 304 is rotatably connected to the wire rope 305 via a movable pulley 303, and the movable pulley 303 is connected to the fixed frame 304 via a bearing seat 307. The two ends of the wire rope 305 are connected to two rope reels 306 respectively to transmit lifting power; the movable pulley 303 is a labor-saving and smooth component, which can halve the pulling force required by the motor, reduce the motor load, and at the same time make the lifting of the fixed frame 304 more stable, avoiding the wire rope 305 from tilting due to unilateral force; the fixed frame 304 is used to fix the feeding bin 4 and convert the tension of the wire rope 305 into the lifting action of the feeding bin 4.

[0032] The top of the feeding bin 4 is fixedly connected to a bin cover 401, which serves a sealing and protective function. This prevents external dust, debris, and livestock excrement from falling into the feeding bin 4 and contaminating the feed; it also prevents feed from spilling from the top when the feeding bin 4 moves or is raised or lowered. The bottom of the feeding bin 4 has a funnel-shaped discharge port, which uses gravity to allow the feed inside to naturally gather at the bottom, preventing feed residue in corners and reducing waste and the risk of mold. It also ensures that the feed flows evenly and smoothly into the lower dispensing mechanism 5, preventing blockages. Multiple reinforcing ribs 402 are fixedly connected between the bin cover 401 and the feeding bin 4, strengthening the connection and preventing the bin cover 401 from falling off due to vibration or livestock collisions. This also increases the structural rigidity of the top of the feeding bin 4, preventing deformation when it is full of feed. One side of the feeding bin 4 has a feed inlet 403, which is rotatably connected to a sealing cap to prevent feed from spilling from the inlet during movement.

[0033] The feeding mechanism 5 includes a feeding storage bin 501, which is sealed and fixedly connected to the discharge port. A rotating impeller 502 is rotatably connected inside the feeding storage bin 501 via a rotating shaft 504. The rotating impeller 502 can adapt to different feed types, such as pellets or powders. The impeller blades of the rotating impeller 502 are in contact with the inner wall of the feeding storage bin 501. When rotating, the cavity between the blades can hold a fixed amount of feed, which is conveyed to the lower discharge port as the impeller rotates, achieving quantitative feeding. When rotation stops, the blades can prevent feed from falling, acting as a seal to prevent leakage and avoid feed blockage. A feeding motor 503 is fixedly connected to the feeding storage bin 501 to drive the rotating impeller 502. The feeding motor 503 precisely adjusts the impeller rotation speed by controlling the motor speed, thereby controlling the amount of feed discharged per unit time, achieving quantitative feeding. Furthermore, the motor's start and stop can quickly control the feeding switch, adapting to sequential feeding from multiple feed troughs.

[0034] Those skilled in the art can use existing technologies they possess, such as installing appropriate mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator during the following operation.

[0035] Working principle: In use, feed is fed into the feeding bin 4 through the feed inlet 403 via an external feeding mechanism. The longitudinal drive motor 1302 is started, driving the drive gear 1304 to rotate. The drive gear 1304 meshes with the rack 1103 on the longitudinal beam 11, driving the sliding plate 1301 and the crossbeam 12 to move longitudinally along the tracks 1102 of the upper guide rail 1101 and the lower guide rail 1104. Simultaneously, the transverse drive motor 203 drives the drive gear of the transverse sliding mechanism 2 to rotate, causing the sliding frame 201 to move laterally along the track of the crossbeam 12. Through the coordinated longitudinal and transverse movements, the feeding bin 4 accurately reaches directly above the target feed trough.

[0036] Then, the lifting reduction motor 302 starts, driving the two sets of rope reels 306 inside the protective shell 301 to rotate synchronously. By winding and unwinding the wire rope 305, the height of the fixing frame 304 is adjusted, so that the feeding bin 4 and the flexible discharge pipe 6 below it are lowered to a suitable height close to the material trough, or raised during the movement to avoid obstacles.

[0037] The feeding motor 503 starts, driving the rotating impeller 502 inside the feeding storage bin 501 to rotate. Feed from the feeding bin 4 flows into the feeding storage bin 501 through the funnel-shaped outlet. The blade cavity of the rotating impeller receives the feed and transports it to the bottom as it rotates, then precisely dispenses it into the trough through the flexible discharge pipe 6. By adjusting the speed of the feeding motor 503, the amount of feed dispensed per unit time can be controlled; stopping the motor blocks the feed from falling, thus achieving feeding start / stop control. Simultaneously, the longitudinal drive motor 1302 and the transverse drive motor 203 move synchronously according to the shape of the trough, enabling feeding into both regular and irregular shaped troughs. This cycle continues.

[0038] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
