Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, and in particular to a feeding device. Background Technology

[0002] Sheep feeding devices are crucial supporting equipment in large-scale sheep farming, directly impacting breeding efficiency and feed utilization. Their types have continuously evolved with changes in farming models, gradually shifting from traditional manual feeding to automated mechanized feeding with data monitoring and calculation to help farmers improve efficiency and feed utilization. The widespread adoption of these devices has effectively promoted the transformation of sheep farming from extensive to intensive feeding, helping to reduce breeding costs and improve the quality of marketable sheep. However, current sheep feeding devices still have many shortcomings in terms of precise data collection. Existing devices cannot distinguish the number of sheep feeding simultaneously, making it difficult to accurately measure feed changes and reliably derive feed conversion ratios from feed variations. Summary of the Invention

[0003] The main objective of this invention is to provide a feeding device designed to more accurately and reliably measure changes in feed.

[0004] To achieve the above objectives, the feeding device proposed in this invention includes a base, a feeding trough, a limiting plate, and a limiting member. The feeding trough is installed on the base and is connected to a weight sensor for weighing the feed inside the trough. The limiting plate is installed on one side of the feeding trough, and an inlet is formed in the thickness direction of the limiting plate, which communicates with the interior of the feeding trough. The limiting member is installed at the inlet, and a first blocking portion and a second blocking portion are formed at both ends along a first direction. A pivot is provided between the first blocking portion and the second blocking portion of the limiting member and is rotatably connected to the limiting plate, so that the first blocking portion and the second blocking portion rotate around the pivot, and one of the first blocking portion and the second blocking portion blocks the inlet. The projected area of ​​the first blocking portion in the thickness direction of the limiting plate is smaller than the projected area of ​​the inlet in the thickness direction of the limiting plate, and the first direction is the length direction of the limiting member.

[0005] In one embodiment, an electromagnetic switch is installed on the limiting plate, and one side of the second blocking part has a magnetic attraction part that cooperates with the electromagnetic switch to magnetically lock the limiting member.

[0006] In one embodiment, the limiting member further includes a limiting rod, which is rotatably connected to one side of the feeding port via the rotating shaft. The two free ends of the limiting rod in the length direction are bent in the radial direction of the limiting rod to form bent tube segments, and the two bent tube segments respectively constitute the first blocking part and the second blocking part.

[0007] In one embodiment, one end of the limiting member extends toward the second direction in a first direction to form a first blocking portion, and the limiting member extends toward the opposite direction of the second direction on the side where the first blocking portion is provided to form a second blocking portion; wherein, the second direction is the radial direction of the limiting member.

[0008] In one embodiment, the limiting plate includes a first connecting plate, a second connecting plate, and an adjusting plate. The first connecting plate and the second connecting plate are installed on both sides of the base, and the adjusting plate is installed between the first connecting plate and the second connecting plate, and together with the first connecting plate, the second connecting plate, and the base, they form the feeding opening.

[0009] In one embodiment, the rotating shaft is further equipped with a torsion spring, and the limiting member is connected to the limiting plate through the rotating shaft and the torsion spring, so that the limiting member rotates relative to the limiting plate under the action of the torsion spring.

[0010] In one embodiment, the limiting member has a plurality of first mounting holes for mounting the rotating shaft to the limiting member.

[0011] In one embodiment, the limiting plate has a plurality of second mounting holes for mounting the rotating shaft to the limiting plate.

[0012] In one embodiment, the feeding device further includes an aisle weighing device disposed on the side of the limiting plate away from the feeding trough, for weighing the animals being fed.

[0013] In one embodiment, the feeding device further includes an identification sensor for identifying the animal being fed.

[0014] In one embodiment, the feeding trough has a partition that divides it into a front cavity and a rear cavity. The bottom edge of the partition is spaced apart from the inner bottom wall of the feeding trough to form a connecting opening. The rear cavity is connected to the front cavity through the connecting opening, and the front cavity is connected to the outside through the feeding inlet. An adjustment plate is installed at the connecting opening to adjust its size.

[0015] In one embodiment, a discharge port is provided on the bottom wall of the feeding trough, and a switch plate is installed inside the discharge port. The switch plate is detachably connected to the discharge port to control the opening and closing of the discharge port.

[0016] In one embodiment, the weight sensors are provided on both sides of the feeding trough, and the two weight sensors are located at the connection between the feeding trough and the base.

[0017] In one embodiment, the base is equipped with an electric telescopic rod, and the feeding trough is connected to the base via the electric telescopic rod to adjust the position of the feeding trough. The weight sensor is located at the connection between the feeding trough and the electric telescopic rod.

[0018] The technical solution of this invention involves providing a feeding trough for feeding sheep, and including a limiting plate with an inlet on its thickness. The side of the limiting plate away from the feeding trough is connected to the inside of the trough, allowing the sheep to feed by inserting its head into the trough through the inlet. Simultaneously, this solution also includes a limiting component with a first and a second blocking portion at both ends. The limiting component is rotatably connected to the limiting plate via a pivot, allowing the sheep to control the limiting position by pressing down or lifting its head while feeding. The rotation of the component causes the first blocking part to release its obstruction of the feeding opening, and drives the second blocking part on the opposite side to block the gap after the sheep's head is inserted, ensuring that only one sheep can eat at a time. The projected area of ​​the first blocking part in the thickness direction of the limiting plate is smaller than the projected area of ​​the feeding opening in the thickness direction of the limiting plate, so that the first blocking part does not completely block the feeding opening, ensuring that the sheep can use its head to insert into the gap between the feeding opening and the first blocking part, thereby pushing the first blocking part to rotate around the pivot to fully insert its head into the feeding opening to eat.

[0019] After feeding, the weight sensor in this solution weighs the feed trough and combines it with the weighing data before the sheep ate to obtain the difference in feed weight, that is, the amount of feed consumed by a single sheep. This allows for more accurate and reliable measurement of feed changes, providing a basis for subsequent data such as feed conversion rate. Attached Figure Description

[0035] Sheep feeding devices are crucial supporting equipment in large-scale sheep farming, directly impacting breeding efficiency and feed utilization. Their types have continuously evolved with changes in farming models, gradually shifting from traditional manual feeding to automated mechanized feeding with data monitoring and calculation to help farmers improve efficiency and feed utilization. The widespread adoption of these devices has effectively promoted the transformation of sheep farming from extensive to intensive feeding, helping to reduce breeding costs and improve the quality of marketable sheep. However, current sheep feeding devices still have many shortcomings in terms of precise data collection. Existing devices cannot distinguish the number of sheep feeding simultaneously, making it difficult to accurately measure feed changes and reliably derive feed conversion ratios from feed variations.

[0036] This invention proposes a feeding device.

[0037] Please see Figure 1 and Figure 2In one embodiment of the present invention, the feeding device includes a base 10, a feeding trough 20, a limiting plate 30, and a limiting member 40. The feeding trough 20 is installed on the base 10 and is connected to a weight sensor 11 for weighing the feed inside the feeding trough 20. The limiting plate 30 is installed on one side of the feeding trough 20, and an inlet 21 is formed in the thickness direction of the limiting plate 30 for communicating with the interior of the feeding trough 20. The limiting member 40 is installed at the inlet 21, and a first blocking portion 41 and a second blocking portion 42 are formed at both ends along a first direction. A pivot 43 is provided between the first blocking part 41 and the second blocking part 42 and is rotatably connected to the limiting plate 30 so that the first blocking part 41 and the second blocking part 42 rotate around the pivot 43 and one of the first blocking part 41 and the second blocking part 42 blocks the feeding port 21; wherein, the orthographic projection area of ​​the first blocking part 41 in the thickness direction of the limiting plate 30 is smaller than the orthographic projection area of ​​the feeding port 21 in the thickness direction of the limiting plate 30, and the first direction is the length direction of the limiting member 40, specifically, the length direction of the middle rod of the limiting member 40.

[0038] In this embodiment of the invention, a feeding trough 20 containing feed is provided for feeding sheep, and a limiting plate 30 is provided, with an inlet 21 formed in the thickness direction of the limiting plate 30, so that the side of the limiting plate 30 away from the feeding trough 20 is connected to the inner side of the feeding trough 20, thereby allowing sheep to feed by inserting their heads into the feeding trough 20 through the inlet 21. Simultaneously, this embodiment also provides a limiting member 40, with a first blocking part 41 and a second blocking part 42 formed at both ends, and the limiting member 40 is rotatably connected to the limiting plate 30 via a rotating shaft 43, thereby allowing sheep to feed by pressing down or lifting their heads. The rotation of the control limiting member 40 is used to push the first blocking part 41 to release the obstruction of the feeding opening 21, and to drive the second blocking part 42 on the opposite side to block the gap after the sheep's head is inserted, ensuring that only one sheep can eat at a time. The projected area of ​​the first blocking part 41 in the thickness direction of the limiting plate 30 is smaller than the projected area of ​​the feeding opening 21 in the thickness direction of the limiting plate 30, so that the first blocking part 41 will not completely block the feeding opening 21, ensuring that the sheep can use the gap between the feeding opening 21 and the first blocking part 41 to insert its head, thereby pushing the first blocking part 41 to rotate around the rotating axis 43, so that the sheep can fully insert its head into the feeding opening 21 to eat. After feeding, the weight sensor 11 in this embodiment weighs the feed trough 20 and combines it with the weighing data before the sheep ate to obtain the difference in feed weight, that is, the amount of feed consumed by a single sheep. This allows for more accurate and reliable measurement of feed changes, providing a basis for subsequent data such as feed conversion rate.

[0039] In one embodiment, an electromagnetic switch 31 is installed on the limiting plate 30, and a magnetic attraction part 32 that cooperates with the electromagnetic switch 31 is provided on one side of the second blocking part 42 for magnetically locking the limiting member 40.

[0040] See Figure 2 and Figure 3 In an embodiment of the present invention, by setting an electromagnetic switch 31, when the weight sensor 11 weighs the feed trough 20, the magnetic part 32 of the second blocking part 42 is attracted, thereby locking the position of the limiting member 40 and the first blocking part 41 on the limiting member 40, blocking the feeding port 21, and preventing the sheep from disturbing the feed trough 20 when eating, thus affecting the weight measurement result of the feed.

[0041] It should be noted that the magnetic part 32 in this embodiment can be any material that can be magnetically attracted by the electromagnetic switch 31, such as a magnet, nickel alloy or cobalt alloy, etc. Specifically, in this embodiment, the magnetic part 32 is made of steel, so that it can be magnetically attracted and locked by the electromagnetic switch 31.

[0042] In one embodiment, the limiting member 40 further includes a limiting rod 44, which is rotatably connected to one side of the feeding port 21 via a pivot 43. The two free ends of the limiting rod 44 in the length direction are bent in the radial direction to form bent tube segments, and the two bent tube segments respectively constitute the first blocking part 41 and the second blocking part 42.

[0043] See Figure 2 and Figure 3 In this embodiment of the invention, by bending both ends of the limiting rod 44 to form bent tube sections, the first shielding part 41 and the second shielding part 42 are constructed. This not only simplifies the structure and facilitates processing, reducing production costs, but also provides high overall strength, capable of withstanding the collisions and friction caused by frequent pushing of the sheep's head. The corners of the bent tube sections are all rounded to prevent scratches on the sheep's body when entering and exiting, thus improving the safety of the equipment.

[0044] It is understandable that the two bent pipe sections constitute the first shielding part 41 and the second shielding part 42. The inner side can also be provided with shielding plates or shielding rods to avoid the middle gap being too large and affecting the shielding effect.

[0045] In one embodiment, one end of the limiting member 40 extends toward the second direction to form a first blocking portion 41, and the limiting member 40 extends toward the opposite direction of the second direction on the side where the first blocking portion 41 is provided to form a second blocking portion 42; wherein, the second direction is the radial direction of the limiting member 40.

[0046] See Figure 2 and Figure 4In an embodiment of the present invention, by setting the first blocking part 41 and the second blocking part 42 on opposite sides of the limiting member 40 and extending in opposite radial directions, the two form a linkage in which at least one of them blocks during rotation, which ensures that the sheep can only push in to eat in one direction, and also ensures that the second blocking part 42 can be stably locked by the electromagnetic switch 31 when weighing, thereby maintaining the partial blocking of the feeding port 21 by the first blocking part 41 and preventing accidental entry that interferes with the measurement.

[0047] It should be noted that, for reference Figure 2 and Figure 3 In this embodiment, the first blocking part 41 blocks the lower end of the feeding opening 21, leaving a gap above the feeding opening 21 so that the sheep's head can penetrate from above and press down on the first blocking part 41, causing the first blocking part 41 to rotate and sink. At this time, the electromagnetic switch 31 is in the closed state. See reference. Figure 4 and Figure 5 The second shielding part 42 moves away from the electromagnetic switch 31 under the pushing action of the first shielding part 41, rotates and blocks the gap between the sheep's head and the feeding opening 21, further preventing multiple sheep from eating at the same time and affecting the weighing of the feed.

[0048] In one embodiment, the limiting plate 30 includes a first connecting plate 33, a second connecting plate 34, and an adjusting plate 35. The first connecting plate 33 and the second connecting plate 34 are installed on both sides of the base 10, and the adjusting plate 35 is installed between the first connecting plate 33 and the second connecting plate 34, and together with the first connecting plate 33, the second connecting plate 34 and the base 10, they form an inlet 21.

[0049] It should be noted that the electromagnetic switch 31, the rotating shaft 43, and the limiting member 40 can all be installed on the first connecting plate 33 or the second connecting plate 34. Specifically, in this embodiment, the electromagnetic switch 31, the rotating shaft 43, and the limiting member 40 are all installed on the first connecting plate 33 as an example.

[0050] In embodiments of the present invention, the adjusting plate 35, the first connecting plate 33, the second connecting plate 34, and the base 10 form a feeding opening 21. The width of the feeding opening 21 can be adjusted by adjusting the distance between the first connecting plate 33 and the second connecting plate 34, and the height of the feeding opening 21 can be adjusted by controlling the height of the adjusting plate 35, thereby adapting to the feeding environment of sheep of different types and sizes. Specifically, a blocking rod 47 can be added and fixedly connected between the first connecting plate 33 and the second connecting plate 34 to limit the sheep's head and ensure that the sheep's head can feed in the designated area.

[0051] In one embodiment, the rotating shaft 43 is also equipped with a torsion spring 45, and the limiting member 40 is connected to the limiting plate 30 through the rotating shaft 43 and the torsion spring 45, so that the limiting member 40 rotates relative to the limiting plate 30 under the action of the torsion spring 45.

[0052] In this embodiment of the invention, a torsion spring 45 is provided so that the limiting member 40 can automatically reset after being rotated under external force, maintaining the blocking state of the feeding opening 21. When the sheep's head enters, it presses against the first blocking part 41, overcoming the elastic force of the torsion spring 45 to open the opening. After feeding, it quickly closes under the restoring force of the torsion spring 45 to prevent subsequent interference. At the same time, the elastic force of the torsion spring 45 can be adjusted according to actual needs to adapt to the entry and exit force requirements of sheep of different types and sizes, enhancing the applicability and stability of the device.

[0053] In one embodiment, the limiting member 40 is provided with a plurality of first mounting holes 46 for mounting the rotating shaft 43 to the limiting member 40.

[0054] In embodiments of the present invention, a plurality of first mounting holes 46 are spaced apart along the length of the limiting member 40 to adjust the mounting positions of the torsion spring 45 and the rotating shaft 43 on the limiting member 40, thereby adjusting the magnitude of the resistance applied to the first blocking part 41, and by adjusting the mounting positions, the blocking areas of the first blocking part 41 and the second blocking part 42 on the feeding port 21 can be adjusted.

[0055] In one embodiment, the limiting plate 30 is provided with a plurality of second mounting holes 36 for mounting the rotating shaft 43 onto the limiting plate 30.

[0056] In embodiments of the present invention, a plurality of second mounting holes 36 are spaced apart in the height direction of the limiting plate 30, so that the rotating shaft 43 can be fixedly connected to the limiting plate 30 at different height positions, thereby adjusting the overall installation height of the limiting member 40, so that the relative position of the first blocking part 41 and the feeding port 21 matches the head size and feeding requirements of different types of sheep, further improving the adaptability of the device.

[0057] In one embodiment, the feeding device further includes an aisle weighing device 50, which is disposed on the side of the limiting plate 30 away from the feeding trough 20, for weighing the animals being fed.

[0058] In an embodiment of the present invention, by setting up a passageway weighing device 50, each sheep that is feeding can be weighed, and then feed conversion rate and other information can be calculated by combining the feed change data obtained by the weight sensor 11, so as to realize the monitoring and management of sheep growth status and feeding efficiency.

[0059] It should be noted that the aisle weighing device 50 in this embodiment can be any device with weighing function and data recording or transmission function. Specifically, in this embodiment, a sensor with weight measurement function is set at the bottom of the support plate, and the weighing signal is transmitted through a cable.

[0060] In one embodiment, the feeding device further includes an identification sensor for identifying the animal being fed.

[0061] In embodiments of the present invention, an identification sensor is provided, which can be installed on the limiting plate or inside the feeding trough to identify sheep that enter the feeding trough through the limiting plate 30 to eat. Combined with the weight data obtained by the aisle weighing device, the feeding management and data collection of individual sheep can be realized.

[0062] It should be noted that the identification sensor in this embodiment can be an RFID reader, an image recognition device, or an infrared sensing device to identify sheep ear tags. Specifically, this embodiment uses an RFID reader as an example. Each sheep wears a corresponding electronic ear tag, which can be used for identification when feeding. In this embodiment, the identification sensor is set as an RFID reader, which receives the identification data of the sheep's electronic ear tags through radio waves and transmits and records it. It can accurately record the amount of feed consumed by each sheep, and can complete information collection without physical contact. It has the advantages of high identification accuracy and fast speed.

[0063] See Figure 6 , Figure 7 and Figure 8 In one embodiment, the feeding trough 20 has a partition 22 inside, which divides the feeding trough 20 into a front cavity 23 and a rear cavity 24. The bottom edge of the partition 22 is spaced apart from the inner bottom wall of the feeding trough 20 to form a connecting opening 25. The rear cavity 24 is connected to the front cavity 23 through the connecting opening 25, and the front cavity 23 is connected to the outside through the feeding port 21. An adjustment plate 28 is installed at the connecting opening 25 to adjust the size of the connecting opening 25.

[0064] In this embodiment of the invention, the feeding trough 20 is divided into a front cavity 23 and a rear cavity 24, with a connecting opening 25 at the bottom. This allows sheep to feed from the front cavity 23, preventing their saliva from contaminating the feed in the rear cavity 24 and preventing subsequent sheep from accessing the feed, thus reducing feed contamination and waste. As the feed in the front cavity 23 descends, the rear cavity 24 continuously replenishes it due to the communicating vessel principle, ensuring sufficient feed in the front cavity 23 while avoiding excessive feeding at once. Furthermore, this embodiment also includes a control plate 28, which can move up and down to adjust the size of the connecting opening 25. After adjustment, it can be fixed by tightening the adjusting bolts, thereby regulating the flow rate of feed from the rear cavity 24 into the front cavity 23 and maintaining the freshness of the feed consumed by the sheep.

[0065] In one embodiment, a discharge port 26 is provided on the bottom wall of the feeding trough 20, and a switch plate 27 is installed inside the discharge port 26. The switch plate 27 is detachably connected to the discharge port 26 to control the opening and closing of the discharge port 26.

[0066] In this embodiment of the invention, a discharge port 26 and a switch plate 27 are provided. When the feed is contaminated or spoiled, or when it needs to be cleaned, the switch plate 27 can be turned on to quickly remove the residual feed at the bottom, improving cleaning efficiency and facilitating the maintenance and cleaning of the feed trough 20. Specifically, in this embodiment, the switch plate 27 is inserted into the discharge port 26. When feed needs to be discharged, the feed can be discharged from the discharge port 26 after the switch plate 27 is pulled out. After discharge, the switch plate 27 can be reinserted into the discharge port 26 to close the discharge port 26.

[0067] In one embodiment, weight sensors 11 are provided on both sides of the feeding trough 20, and the two weight sensors 11 are located at the connection between the feeding trough 20 and the base 10.

[0068] In the embodiments of the present invention, by setting two weight sensors 11 and symmetrically arranging the two weight sensors 11 on both sides of the feed trough 20, the weight change of the feed in the feed trough 20 can be monitored more accurately, reducing the measurement error caused by uneven force on the feed trough 20 due to the weight sensor 11 being set on one side, thereby improving the accuracy of the measurement.

[0069] See Figure 9 In one embodiment, the base 10 is equipped with an electric telescopic rod 12, and the feeding trough 20 is connected to the base 10 through the electric telescopic rod 12 to adjust the position of the feeding trough 20. The weight sensor 11 is set at the connection between the feeding trough 20 and the electric telescopic rod 12.

[0070] In an embodiment of the present invention, the feed trough 20 is connected to the base 10 via an electric telescopic rod 12, allowing the operator to adjust the height of the feed trough 20 by adjusting the electric telescopic rod 12 to accommodate the feeding needs of sheep of different sizes. At the same time, the weight sensor 11 monitors the weight of the feed in real time.

[0071] It is understood that the electric telescopic rod 12 can be directly connected to the side or bottom of the feeding trough 20 to achieve height adjustment of the feeding trough 20, or it can be used in conjunction with other support structures to achieve height adjustment. Specifically, in this embodiment, a crossbar is connected below the weight sensors 11 on both sides of the feeding trough 20. The crossbar is slidably connected to the base 10. The bottom of the crossbar is connected to the bottom of the base 10 through the electric telescopic rod 12, which can be raised and lowered, thereby achieving height adjustment of the feeding trough 20 through the electric telescopic rod 12.

[0072] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
