Description

Technical Field

[0001] This invention relates to the field of livestock breeding equipment technology, and in particular to a livestock feeder for unmanned aerial vehicle docking. Background Technology

[0002] Currently, with the continuous development of drone technology, drones are being used more and more in the agricultural field. Especially in agricultural spraying and fertilization, drones are playing an increasingly important role. A typical drone can carry tens of kilograms of pesticides or fertilizers, requiring frequent refueling and loading operations. Currently, these operations are mostly performed manually. However, manual loading is not only cumbersome, but also requires dedicated personnel for each drone, affecting efficiency and safety; improper operation can easily lead to safety problems.

[0003] In recent years, the application of drone technology in livestock farming has gradually become widespread. Using drones to achieve cross-regional transfer and fixed-point delivery of feed has become an effective way to solve the feeding problems of decentralized farms. However, the docking process between drones and feeders in existing technologies generally has the following defects: existing trough feeders use traditional feed inlets and do not have a docking platform corresponding to drones. As a result, when drones directly dock with the feed inlet, the docking positioning accuracy is low, and it is difficult for the drone's feed inlet to quickly align with the feeder's feed hopper, which easily leads to feed spillage and waste. At the same time, existing equipment has relatively simple functions in terms of feed residue treatment, animal isolation feeding, and trough cleaning, and lacks an integrated automatic cleaning and isolation mechanism, which makes it difficult to meet the actual needs of modern large-scale farming for intelligent and automated equipment. In view of this, we propose a livestock trough feeder for drone docking. Summary of the Invention

[0033] Reference Figure 1-15 As shown, a livestock feeder for unmanned aerial vehicle (UAV) docking includes: Feed silo 1, feed hopper 16 is fixedly installed on feed silo 1, and drone docking device 10 is set on feed hopper 16 to realize precise feeding by drone. Circular feed trough inclined hopper 3 is fixedly connected to the surface of feed silo 1 through connecting frame 2. The circular feed trough inclined hopper 3 has a discharge port in the center. Circular feed trough inclined hopper 3 has an inner and outer stepped structure, with the inner layer bottom and the outer layer high, both inclined towards the discharge port. Support column 4 is fixedly connected to the bottom of circular feed trough inclined hopper 3. Feeding hopper 5 is located inside the feed silo 1. The feeding hopper 5 is equipped with a feeding and cleaning device 6 to promote uniform feeding and reduce feed residue. A magnetic iron valve 7 is slidably connected to the outer wall of the feed silo 1. An electromagnetic coil 8 is fixedly connected to the outer wall of the feed silo 1 above the magnetic iron valve 7. Both the magnetic iron valve 7 and the outer wall of the feed silo 1 are provided with a discharge port 19. When the magnetic iron valve 7 is in the lowered state (normal state), the discharge port 19 on the magnetic iron valve 7 is aligned with the discharge port 19 on the feed silo 1. The scraping and separating device 9 is installed on the feed silo 1 for feed splitting and residual material cleaning.

[0034] The circular feed trough hopper 3 has two inclined areas. The inclined area on the outer ring of the magnetic iron valve 7 is used to place food for feeding animals, and the inclined area on the inner ring of the magnetic iron valve 7 is used for discharging. Under normal conditions, the bottom of the magnetic iron valve 7 is in contact with the circular feed trough hopper 3. When the magnetic iron valve 7 moves upward, the gap between the circular feed trough hopper 3 and the bottom of the feed silo 1 is leaked. At this time, the food on the outer ring is affected by inertia and guided by the inclined area, causing the food around to be concentrated and discharged from the discharge port, thereby achieving the effect of centralized feeding and collection, avoiding problems such as food splashing. The circular feed silo 1 allows multiple animals to feed in a circular distribution, further increasing the number of animals raised in the feed silo 1. Combined with the feeding and cleaning device 6 and the scraping and isolation device 9, the effect of automated cleaning and centralized collection of food residue is achieved.

[0035] In this embodiment, the UAV docking device 10 includes a docking platform 101, a horizontal electric push rod 102, a vertical electric push rod 103, a horizontal docking clamp 104, and a vertical docking clamp 105. The docking platform 101 is fixedly connected to the feed hopper 16 and has a discharge port in the center aligned with the feed hopper 16. The horizontal electric push rod 102, the vertical electric push rod 103, the horizontal docking clamp 104, and the vertical docking clamp 105 are all set in two groups and are symmetrically distributed along the central axis of the docking platform 101. The two horizontal docking clamps 104 are fixedly connected to the output shafts of the two horizontal electric push rods 102 one-to-one, and the two vertical docking clamps 105 are fixedly connected to the output shafts of the two vertical electric push rods 103 one-to-one. The two horizontal docking clamps 104 pass through the corresponding vertical docking clamps 105 and form a sliding fit with them. The horizontal electric push rods 102 and the vertical electric push rods 103 are both fixedly connected to the docking platform 101. The horizontal electric push rod 102 and the vertical electric push rod 103 drive the two horizontal docking clamps 104 and the vertical docking clamps 105 to move relative to each other, thereby achieving rapid clamping and positioning of the drone's feeding port. The symmetrically arranged horizontal and vertical docking clamps form a cross-clamping structure, which can accurately position the drone in both horizontal and vertical directions, ensuring that the drone's feeding port is quickly aligned with the feeding hopper 16, effectively reducing feed spillage during the docking process and improving feed utilization.

[0036] It is worth noting that the feed silo 1 is provided with a mixing chamber 11 and a distributing chamber 12. A discharging valve 13 is fixedly installed at the bottom of the mixing chamber 11. The distributing hopper seat 5 is located at the bottom of the distributing chamber 12. A mixing motor 14 is installed at the top of the feed silo 1. The output shaft of the mixing motor 14 extends to the feed silo 1 and is coaxially connected to a mixing rod 15. A collection frame 17 is installed at the bottom of the circular feed trough inclined hopper 3. A collection box 18 is snapped into the inside of the collection frame 17. The drone feeds the feed into the mixing chamber 11 through the feeding hopper 16. The mixing motor 14 is started as needed to drive the mixing rod 15 to mix and stir the feed. The mixed feed is quantitatively discharged into the distributing chamber 12 through the discharging valve 13. The feed is automatically slid and distributed by the influence of the arc-shaped distributing hopper seat 5. The collection box 18 is used to collect the feed discharged from the discharge area inside the circular feed trough inclined hopper 3.

[0037] In addition, the feeding and cleaning device 6 includes an active motor 61 and a distributing arc rod 64. The end of the active motor 61 is fixedly installed inside the distributing hopper 5. The output shaft of the active motor 61 is coaxially connected to an active bevel gear 62. The distributing arc rod 64 is rotatably connected to the top center of the distributing hopper 5 through a rotating rod. The lower end of the rotating rod is coaxially connected to a passive bevel gear 63. The active bevel gear 62 and the passive bevel gear 63 mesh. The mixed feed is quantitatively fed into the distributing chamber 12 through the feeding valve 13. The feed is automatically slid and distributed under the influence of the arc-shaped distributing hopper 5. During the distributing process, the active motor 61 can be started. The output shaft of the active motor 61 rotates through the active bevel gear 62 meshing with the passive bevel gear 63. The passive bevel gear 63 drives the distributing arc rod 64 to rotate and distribute the feed on the distributing hopper 5. This promotes uniform feeding of the feed, increases the feeding rate of the feed, and further reduces the problem of feed sticking to the distributing hopper 5 and causing residual pollution.

[0038] Furthermore, the cleaning mechanism 65 includes an I-shaped chuck 651, which is coaxially rotatably connected to the bottom of the feed silo 1. A key shaft 652 is fixedly connected to the top of the I-shaped chuck 651, and a clearance bevel gear 653 is slidably connected to the surface of the key shaft 652. A retaining ring 654 is slidably connected to the bottom of the I-shaped chuck 651, and an inclined scraper 656 is fixedly connected to the bottom of the retaining ring 654 via a connecting rod 655. A spring is fixedly connected between the bottom of the clearance bevel gear 653 and the top of the I-shaped chuck 651. By setting a spring and key shaft 652, the yielding bevel gear 653 achieves an elastic yielding effect when meshing with the driving bevel gear 62 upwards, thereby avoiding the problem of tooth collision between the yielding bevel gear 653 and the driving bevel gear 62. When interference occurs, the yielding bevel gear 653 will automatically compress its upper spring to yield. After yielding and returning to a non-interference state, the yielding bevel gear 653 will automatically reset, achieving close meshing with the driving bevel gear 62. Multiple long rods 65 are fixedly connected to the I-shaped chuck 651. 7. The inner ring of the magnetic iron valve 7 has multiple concave grooves 658, and the ends of multiple long rods 657 are slidably connected to the multiple concave grooves 658. When the electromagnetic coil 8 is energized, it generates a high magnetic force to quickly attract the magnetic iron valve 7. The magnetic iron valve 7 moves upward and attaches to the electromagnetic coil 8. During the upward movement, the magnetic iron valve 7 drives the I-shaped chuck 651 on the long rods 657 to move upward as a whole through the concave grooves 658 of its inner ring. The I-shaped chuck 651 drives the clearance bevel gear 653 to move upward as a whole. After the clearance bevel gear 653 moves upward, it meshes with the driving bevel gear 62. When the driving bevel gear 62 rotates, it can mesh with the yielding bevel gear 653 to rotate. The yielding bevel gear 653 drives the I-shaped chuck 651 to rotate as a whole through the key shaft 652. When the I-shaped chuck 651 rotates, it drives the retaining ring 654 to rotate as a whole through the sliding shaft. The retaining ring 654 drives the inclined scraper 656 to rotate and clean in the discharge cavity inside the circular feed trough inclined hopper 3 through the connecting rod 655, further promoting the concentrated feeding of food into the collection box 18, achieving the effect of automated cleaning and concentrated collection of food residue.

[0039] Furthermore, the scraping and isolating device 9 includes a fixed base 91, the inner wall of which is fixedly connected to the outer wall of the feed silo 1. A through seat 92 is rotatably connected to the bottom end of the fixed base 91, and the interior of the fixed base 91 is sealed and connected to the through seat 92. A rotating seat 93 is fixedly connected to the bottom of the through seat 92. Multiple mounting slots are evenly spaced on the rotating seat 93, and a nozzle 94 is rotatably connected in each mounting slot. A torsion spring is provided at the rotatable connection of each nozzle 94, and each nozzle 94 is connected to the bottom of the through seat 92. The parts are fixedly connected by hoses 95. The bottom of the rotating seat 93 is fixedly connected with multiple dividing scrapers 96 in a ring array. The top of the fixed base 91 is fixedly connected to the feed pipe 97, which communicates with the through seat 92. The feed pipe 97 is connected to a water source and a water pump. The water source is controlled by the water pump to enter the fixed base 91. The fixed base 91 then feeds the water source from the through seat 92 and the rotating seat 93 into the nozzles 94 connected by each hose 95. The nozzles 94 then spray the water onto the inner wall of the circular feed trough inclined hopper 3 for cleaning. The interior of the fixed base 91 is connected to the interior of the through seat 92. The through seat 92 is connected to the interior of the nozzle 94 through the hose 95. The surface of the dividing scraper 96 is slidably connected to the surface of the magnetic iron valve 7. The magnetic iron valve 7 has a groove for limiting the sliding of the dividing scraper 96. When the I-shaped chuck 651 rotates, it can drive the magnetic iron valve 7 on the concave groove 658 to rotate as a whole through the long rod 657 on it. The magnetic iron valve 7 drives the rotating seat 93 on the dividing scraper 96 to rotate as a whole through the groove on it. When the dividing scraper 96 rotates in the circular feed trough hopper 3, it can scrape and clean the food residue inside. During the rotation, the dividing scraper 96 drives the through seat 92 to rotate as a whole through the rotating seat 93. The nozzle 94 can realize the rotation cleaning work of the circular feed trough hopper 3.

[0040] In addition, a protrusion 98 is fixedly connected to the fixed base 91, a protrusion 99 is fixedly connected to the nozzle 94, and a spring strip 21 is fixedly connected to the connecting frame 2. When the rotating base 93 rotates as a whole, the protrusion 99 on the nozzle 94 will intermittently contact the protrusion 98 to achieve elastic displacement. After elastic displacement, the nozzle 94 can achieve axial rotation, further improving the cleaning area of ​​the inner wall of the circular feed trough hopper 3, thereby achieving a comprehensive cleaning effect of the nozzle 94 on the inner wall of the circular feed trough hopper 3, avoiding the problem of food residue caused by cleaning dead corners. At the same time, the dividing scraper 96 during rotation will intermittently contact and impact the spring strip 21. The impact will produce a slight vibration, which can further promote the feeding of food residue on the dividing scraper 96 itself.

[0041] The working process and principle of this invention are as follows: In use, after the drone is loaded with feed, it positions itself above the feeder using the navigation system and hovers. The drone sends a docking request signal to the feeder's control unit via a wireless communication module. Upon receiving the signal, the control unit activates the drone docking device 10. At this time, both the horizontal electric push rod 102 and the vertical electric push rod 103 are in the retracted state, maximizing the clamping space formed by the horizontal docking clamp 104 and the vertical docking clamp 105, facilitating drone entry. The drone gradually descends to the bottom of its fuselage and the upper surface of the docking platform 101. The control unit collects the drone's real-time position information through a laser positioning sensor installed at the center of the docking platform 101, driving the horizontal electric push rod 102 to extend, causing the horizontal docking clamp 104 to move horizontally towards the drone's fuselage. When the horizontal clamp contacts the drone's fuselage and reaches the docking point... When the preset pressure value is reached, the horizontal electric push rod 102 stops moving; then the vertical electric push rod 103 extends, driving the vertical docking clamp 105 to move towards the drone body in the vertical direction until the clamping and positioning are completed. At this time, the drone's feeding port is precisely aligned with the unloading port of the docking platform 101. After the clamping and positioning are completed, the control unit sends a feeding signal to the drone. The drone opens the feeding port, and the feed slides down the feeding hopper 16 into the feed silo 1 for storage. The funnel-shaped structure of the feeding hopper 16 ensures that the feed is not spilled. After the feed is fed, the drone sends a release signal to the control unit. The control unit first drives the vertical electric push rod 103 to retract, and then drives the horizontal electric push rod 102 to retract, so that the clamp detaches from the drone body. The drone starts the lift system and flies away. The docking device returns to the initial state and waits for the next docking.

[0042] Feed entering the feed silo 1 first reaches the mixing chamber 11. At this time, the mixing motor 14 is started to drive the mixing rod 15 to mix and stir the feed. The mixed feed is then quantitatively discharged into the distribution chamber 12 through the feeding valve 13. The feed is automatically slid and distributed by the arc-shaped distribution hopper 5. During the distribution, the active motor 61 can be started. The output shaft of the active motor 61 rotates through the active bevel gear 62 meshing with the passive bevel gear 63. The passive bevel gear 63 drives the distribution arc rod 64 to rotate and distribute the feed on the distribution hopper 5. This promotes uniform feeding and increases the feeding rate, and further reduces the problem of feed sticking to the distribution hopper 5 and causing residual pollution. The discharged feed is discharged into the circular feed trough inclined hopper 3 through the feeding port 19. The animals eat in a dispersed manner on the circular feed trough inclined hopper 3, and the multiple dividing scrapers 96 distributed in a circular array achieve the effect of automatic isolation of the animals. The use of the circular feed silo 1 allows multiple animals to eat in a circular distribution, further increasing the number of animals raised in the feed silo 1.

[0043] After completing the feeding operation, the drone can hover above the feed silo 1 to monitor the animals' feeding status in real time. Once the animals have finished feeding, the drone sends the information to the central control platform. Upon receiving the information, the platform activates the electromagnetic coil 8. The electromagnetic coil 8 generates a high magnetic force that quickly attracts the magnetic iron valve 7. The magnetic iron valve 7 moves upward and attaches to the electromagnetic coil 8. During this upward movement, the magnetic iron valve 7 drives the I-shaped chuck 651 on the long rod 657 to move upward through the concave groove 658 of its inner ring. The I-shaped chuck 651 drives the clearance bevel gear 653 to move upward. After moving upward, the clearance bevel gear 653 meshes with the driving bevel gear 62. When the driving bevel gear 62 rotates, it can engage the clearance bevel gear 653 to rotate. The clearance bevel gear 653 drives the I-shaped chuck 653 through the key shaft 652. The I-shaped chuck 651 rotates as a whole. When the I-shaped chuck 651 rotates, it drives the magnetic iron valve 7 to rotate as a whole through the long rod 657 on it. The magnetic iron valve 7 drives the rotating seat 93 on the dividing scraper 96 to rotate as a whole through the sliding groove on it. When the dividing scraper 96 rotates in the circular feed trough hopper 3, it achieves the effect of scraping and cleaning the residual feed inside. As the magnetic iron valve 7 moves upward, the gap between the circular feed trough hopper 3 and the bottom of the feed silo 1 leaks out. At this time, the scraped residual feed slides from the outer ring area of ​​the circular feed trough hopper 3 to the inner ring area along the slope and is pushed by the rotating dividing scraper 96 from the discharge port into the collection box 18, thus achieving the effect of automatically cleaning the residual feed inside the circular feed trough hopper 3.

[0044] During the cleaning process, water is pumped into the fixed base 91 and then fed from the fixed base 91 into the nozzles 94 connected to the hoses 95 via the through seat 92 and the rotating seat 93. The nozzles 94 then spray water onto the inner wall of the circular feed trough hopper 3 for cleaning. Correspondingly, the dividing scraper 96 rotates the through seat 92 via the rotating seat 93. The nozzles 94 can perform rinsing and cleaning of the circular feed trough hopper 3. During rotation, the protruding rod 99 on the nozzle 94 intermittently contacts the protruding seat 98 to achieve elastic displacement. After elastic displacement, the nozzle 94 can rotate axially, further increasing the cleaning range of the circular feed trough hopper 3 and avoiding food residue problems caused by cleaning dead corners, thereby effectively preventing animals from eating rotten and decaying food.

[0045] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not describe the various possible combinations separately.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
