Description

Technical fields:

[0001] This invention relates to the field of animal husbandry, specifically to a livestock feeding system consisting of a neck yoke and a feeding trough. Background technology:

[0002] Animal husbandry mainly includes the raising of livestock and poultry such as cattle, horses, donkeys, mules, camels, pigs, sheep, chickens, ducks, geese, rabbits, and bees, as well as the domestication of wild economic animals such as deer, mink, otters, and musk deer. It not only provides raw materials for industries such as textiles, oils, food, and pharmaceuticals, but also provides people with abundant food such as meat, milk, eggs, and poultry, and provides draft animals and manure for agriculture. Therefore, developing animal husbandry is of great significance for promoting economic development, improving people's lives, and increasing exports.

[0003] In animal husbandry, cattle and sheep are the most commonly raised livestock. During the production and breeding process of these livestock, they need to be fed. Feed troughs are used to hold the feed. At the same time, a neck yoke is installed on one side of the feed trough to restrict the animals' necks, prevent them from butting and fighting for food, and make it easier for users to handle them.

[0004] Traditional neck yokes require manual operation to restrict or unlock an animal's neck. Since there are a large number of animals in conventional breeding, it is tedious to operate on each animal every time, which reduces work efficiency and increases labor intensity.

[0005] Secondly, existing feeding troughs often come in two forms: one is a separate trough for each animal, and the other is a long, open trough. Each time feed is added to the trough, a feed cart needs to be pushed on one side, and the feed cart needs to be manually moved back and forth between the feed cart and the trough. This makes it impossible to feed continuously and causes inconvenience to the user. Summary of the Invention:

Detailed implementation method:

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Example 1:

[0057] like Figures 1 to 6As shown, a livestock feeding system consisting of a neck yoke and a feeding trough includes a long trough 1 and a base 2 placed on one side of the long trough 1. Multiple neck yokes 3 are arranged at equal intervals on the top of the base 2. The system also includes a feed cylinder 4 that extends the length of the long trough 1 and moves backward. The feed cylinder 4 has rotatable wheels 9 on its sides that roll in contact with the top of both sides of the long trough 1. The feed cylinder 4 slides on the long trough 1 via the wheels 9. The feed cylinder 4 is positioned above the opening of the long trough 1, and its bottom surface slides in contact with the bottom of the long trough 1, making the bottom surface of the feed cylinder 4 as close as possible to the bottom of the long trough 1. The discharge port 5 of the feed cylinder 4 communicates with the long trough 1. A feeding hole 7 is opened at the bottom of the long trough 1 corresponding to the neck channel 6 of the neck yoke 3. A feeding bucket 8 communicating with the feeding hole 7 is fixed at the bottom of the long trough 1.

[0058] A feeding bowl 10 is slidably installed inside each feeding bucket 8, with the edge of the feeding bowl 10 fitting against the inner wall of the feeding bucket 8. A crankshaft 11 is horizontally rotatable inside the feeding bucket 8 below the feeding bowl 10, with both ends of the crankshaft 11 passing through the side wall of the feeding bucket 8. A connecting rod 12 is provided between the feeding bowl 10 and the crankshaft 11, with both ends hinged to the feeding bowl 10 and the crankshaft 11 respectively. One end of the crankshaft 11 is located on the outside of the feeding bucket 8. A feeding bucket rocker arm 13 is provided on the crankshaft 11 on the outside of the feeding bucket 8.

[0059] A cavity 14 is opened at one end of the long groove 1. One side of the cavity 14 is connected to the outside of the long groove 1. A crank 15 is rotatably provided on the long groove 1 through the cavity 14. A crank arm 16 is fixed on the crank 15 outside the cavity 14.

[0060] A ratchet 17 is provided on the crank handle 15 inside the cavity 14. The ratchet 17 is coaxially sleeved and fixed with the crank handle 15. A ratchet tooth 18 is provided below the ratchet 17 to mesh with the ratchet 17. A locking pedal 19 is fixed on the ratchet tooth 18 and rotatably connected to the inner wall of the cavity 14. One end of the locking pedal 19 is placed outside the long groove 1. A blind hole 20 is provided at the bottom of the cavity 14. A spring 21 and a pressure block 22 are provided in the blind hole 20. The bottom end of the pressure block 22 is fixed to the top end of the spring 21. The bottom end of the spring 21 is fixed to the bottom of the blind hole 20. The top end of the pressure block 22 abuts against the locking pedal 19.

[0061] A linkage 23 is provided between multiple feeding buckets 8 and crank handle 15; the feeding bucket rocker arm 13 and the crank handle rocker arm 16 are both hinged to the linkage 23, and the feeding bucket rocker arm 13 and the crank handle rocker arm 16 have the same structure.

[0062] Each neck yoke 3 includes two gantry frames 24, forming a neck channel 6 between the two gantry frames 24, and a neck-limiting structure 25 on each gantry frame 24; a long rod 26 is horizontally rotatable on the base 2, and an unlocking structure 27 is provided on the long rod 26 that is pulsatorically connected to the neck-limiting structure 25.

[0063] The neck-limiting structure 25 includes an L-shaped height-limiting rod 28, one end of which is hinged to the top of the gantry frame 24, and the other end of which is fixedly connected to one end of a compression spring 29, and the other end of the compression spring 29 is fixedly connected to the top of the gantry frame 24.

[0064] The two height restriction bars 28 of each neck yoke 3 are set at opposite corners;

[0065] The unlocking structure 27 includes a pull rope 30 that is fixedly connected at both ends to the height limit bar 28 and the long bar 26 respectively. A horizontal beam 31 is provided on the gantry frame 24 below the height limit bar 28. A limit ring 32 is fixed on the beam 31, and the pull rope 30 passes through the limit ring 32.

[0066] Working principle: In this embodiment, when the animal's neck is inserted into the neck channel 6, it lowers its head and presses down on the two height-limiting rods 28, causing the compression spring 29 to retract. After passing through, the spring 29's elastic force causes the height-limiting rods 28 to return to their original position and lift up. At this time, the animal's neck can be restricted from lifting up. The neck channel 6 is used to restrict the animal's neck from moving left and right. Rotating the long rod 26 causes the height-limiting rods 28 to rotate and descend via the pull rope 30, clearing the obstruction above the neck channel 6 and releasing the lock. After feeding is completed, the long rod 26 drives multiple pull ropes 30 to lower the height-limiting rods 28, which can effectively release the restriction on all animals at the same time. It is convenient to use.

[0067] When feeding, feed is placed in the feed cylinder 4 and pushed along the long trough 1. The feed falls naturally into the long trough 1 through the discharge port 5. Since the bottom of the feed cylinder 4 is close to the bottom of the long trough 1, the discharge port 5 can scrape the feed as it moves. The bottom of the long trough 1 supports the feed, preventing it from falling out of the feed cylinder 4. When it moves to the top of the feeding bucket 8, there is a height difference, and the feed falls into the feeding bowl 10 of the feeding bucket 8, completing the feeding. As long as the feed cylinder 4 is pushed along the long trough 1, the feed in the feeding bucket 8 falls, which can achieve continuous feeding, improve efficiency, and make it convenient to use. At the same time, excess feed is carried away to the next feeding bucket 8, which can accurately and evenly control the amount of feed.

[0068] By moving the linkage 23 back and forth, the linkage 23 drives each crankshaft 11 to rotate forward or backward via the feeding bucket rocker arm 13. The crankshaft 11 further drives the feeding bowl 10 to rise or fall within the feeding bucket 8 via the connecting rod 12, thereby changing the volume between the top of the feeding bucket 8 and the feeding bowl 10. When the feeding bowl 10 is lowered, more feed can be placed in it, and vice versa. This meets the usage requirements.

[0069] The linkage 23 can be controlled by ratchet 17 and ratchet 18. Specifically, when the pressure block 22 is pushed upward against the locking pedal 19 by the spring force of spring 21, the ratchet 18 engages with ratchet 17, the crank handle 15 is locked, and the linkage 23 cannot move. After the locking pedal 19 is lifted by the foot, the pressure block 22 rotates, the ratchet 18 disengages from ratchet 17, and the lock is released. Turning the crank handle 15 can drive the linkage 23 to move through the crank arm 16. At the same time, the crank arm 16 rotates and drives the ratchet 17 to rotate, locking the teeth of the ratchet 17 at different positions, which can meet the needs of controlling the change of the volume of the food bowl 10.

[0070] Example 2:

[0071] like Figures 7 to 9 As shown, a livestock feeding system consisting of a neck yoke and a feeding trough has the same overall structure as in Embodiment 1. The difference is that the feed cylinder 4 is placed above one side of the opening of the long trough 1, and a track 33 is fixedly connected to the long trough 1 below the feed cylinder 4. The feed cylinder 4 is rotatably equipped with a traveling wheel 9 that rolls in contact with the top of one side of the long trough 1 and the track 33. The feed cylinder 4 moves along one side edge of the long trough 1 through the traveling wheel 9. A cover 34 is fixedly provided on the side wall of the feed cylinder 4 and placed above the opening of the long trough 1. The cover 34 has openings at both the top and bottom, and the bottom opening of the cover 34 slides in contact with the bottom of the long trough 1. The bottom of the cover 34 is as close as possible to the bottom of the long trough 1.

[0072] The bottom of the material cylinder 4 has a discharge port 5 that communicates with the inner cavity of the cover 34.

[0073] Working Principle: In this embodiment, the overall principle is the same as that of Embodiment 1. The difference is that feed is placed in the feed cylinder 4. The feed cylinder 4 is pushed to move along the top of one side of the long trough 1 and the track 33. The feed falls naturally through the discharge port 5 and into the long trough 1 through the bottom opening of the cover 34. The bottom of the cover 34 scrapes the feed as it moves, and the bottom of the long trough 1 supports the feed, preventing it from falling out of the feed cylinder 4. When the feed cylinder 4 moves to the top of the feeding bucket 8, there is a height difference, and the feed falls into the feeding bowl 10 of the feeding bucket 8, completing the feeding. As long as the feed cylinder 4 is pushed to move along the long trough 1, the feeding bucket 8 can be fed naturally, which can achieve continuous feeding, improve efficiency, and is convenient to use. At the same time, excess feed is carried away to the next feeding bucket 8, which can accurately and evenly control the feeding amount. The top opening of the cover 34 makes it easy to observe the feed falling, avoiding the situation where the feed falls poorly but goes unnoticed, affecting the continuity of feeding.

[0074] Example 3:

[0075] like Figures 10 to 14As shown, a livestock feeding system consisting of a neck yoke and a feeding trough has the same overall structure as in Embodiment 1 or 2, except that the neck restraint structure 25 includes a Z-shaped rod 35. The middle rod 36 of the Z-shaped rod 35 is hinged to a vertical rod 37 of the gantry frame 24. A locking plate 38 is fixed to the bottom end of the Z-shaped rod 35. A notch 39 is provided on the side of the locking plate 38. The notch 39 is a right-angled trapezoid with three right-angled sides and one hypotenuse. One right-angled side is connected to the side of the locking plate 38. A connecting rod 40 is horizontally provided on the upright 37 below the hinge point of the rod 35 and the upright 37. The connecting rod 40 is placed between the two uprights 37 of the gantry frame 24. A locking rod 41 is rotatably provided on the connecting rod 40. The locking rod 41 is vertical due to its own weight. A tension spring 42 is provided between the connecting rod 40 and the intermediate rod 36 of the Z-shaped rod 35. One end of the tension spring 42 is fixedly connected to the connecting rod 40, and the other end of the tension spring 42 is fixedly connected to the intermediate rod 36 above the hinge point of the Z-shaped rod 35 and the upright 37.

[0076] A ring 43 is fixed to the top of the gantry frame 24. A limiting rod 44 is vertically inserted inside the ring 43. The inner diameter of the ring 43 is larger than the outer diameter of the limiting rod 44. A top rod 45 is horizontally fixed on another upright 37 of the gantry frame 24. The top rod 45 is placed between the two uprights 37 of the gantry frame 24. A crossbeam 31 is horizontally fixed between the two uprights 37 of the gantry frame 24. A stop rod 46 perpendicular to the top rod 45 is horizontally fixed on the crossbeam 31.

[0077] The unlocking structure 27 includes a fixed support rod 47, a connecting support rod 48, a locking push rod 49, and a limiting push rod 50. The fixed support rod 47 is fixed on the long rod 26 and is perpendicular to the long rod 26. The connecting support rod 48 is fixed on the fixed support rod 47 and is perpendicular to both the long rod 26 and the fixed support rod 47. The locking push rod 49 and the limiting push rod 50 are fixed on the connecting support rod 48 and are parallel to the long rod 26. The locking push rod 49 and the locking rod 41 are in separate movable contact. The limiting push rod 50 and the limiting rod 44 are in separate movable contact.

[0078] Working principle: The overall principle of this embodiment is the same as that of Embodiment 1 or 2, except that the neck yoke 3 in this embodiment has three usage states. The first state is normal locking of the animal's neck (e.g., Figure 13 As shown), when the animal's neck is inserted into the neck channel 6, it touches the Z-shaped rod 35 downwards. The bottom of the Z-shaped rod 35 rotates counterclockwise toward the gantry frame 24. The bottom end of the Z-shaped rod 35 moves along an arc-shaped trajectory, causing the locking plate 38 to move toward the locking rod 41. The inclined side of the notch 38 pushes open the limiting rod 31. As the locking plate 38 passes over the locking rod 41, the locking rod 41 blocks the locking plate 38 by self-resetting. The tension spring 42 cannot pull the upper part of the Z-shaped rod 35 to reset. At this time, the top of the Z-shaped rod 35 is horizontal at the top of the neck channel 6 to restrict the animal's neck from lifting, thus achieving the locking and limiting effect.

[0079] The second method is to unlock (such as...) Figure 10 As shown), by rotating the long rod 26, the fixed support rod 47, connecting support rod 48, locking push rod 49, and limiting push rod 50 move towards the limiting rod 44. The locking push rod 49 pushes open the locking rod 41, and the tension spring 42 pulls the upper part of the Z-shaped rod 35 back to its original position, releasing the lock plate 38. This method sets multiple corresponding unlocking structures 27 on multiple long rods 26, which can unlock all neck locking devices 2, making it convenient to release all animals at the same time. It can also be used when the locking rod 41 blocks the lock plate 38 (e.g. Figure 14 As shown), insert the limiting rod 44 corresponding to the animal that needs to be left alone into the notch 39. When the locking rod 41 is released, it is still blocked by the limiting rod 44 and cannot be unlocked. The other animals can be unlocked. This combines the functions of unlocking all animals and unlocking one animal at a time. It is convenient to use and widely applicable. If you want to unlock the limiting rod 44, you can continue to rotate the long rod 26. The limiting push rod 50 will push the limiting rod 44 open, and the one animal left alone will be unlocked.

[0080] The third method to prevent animals from accidentally entering the neck passage 6 (e.g.) Figure 12 As shown, the position of the limiting rod 44 is adjusted so that it is held in place by the top rod 45. When the animal's neck touches the Z-shaped rod 35 downwards, the locking plate 38 is blocked by the limiting rod 44. The top rod 45 provides reverse support to the limiting rod 44. The bottom end of the Z-shaped rod 35 cannot move along the arc-shaped movement trajectory, and the locking plate 38 is not locked by the locking rod 41, thus avoiding manual unlocking.

[0081] Example 4:

[0082] like Figures 15 to 22 As shown, a livestock feeding system consisting of a neck yoke and a feeding trough has the same overall structure as in embodiments 1, 2 or 3, except that the neck yoke structure 25 includes a T-shaped frame 51, which includes a vertical rod 52 and a horizontal rod 53 vertically fixed to the top of the vertical rod 52.

[0083] The vertical rod 52 is hinged to the middle of one of the uprights 37 of the gantry frame 24. A tension spring connecting rod 54 is horizontally fixed between the two uprights 37 of the gantry frame 24. A tension spring rod 55 parallel to the horizontal rod 53 is provided on the side wall above the hinge end of the vertical rod 52. A tension spring 42 with its two ends fixed to the tension spring rod 55 and the tension spring connecting rod 54 is provided between the tension spring rod 55 and the tension spring connecting rod 54 respectively.

[0084] An S-shaped locking rod 56 is hinged to the top of the gantry frame 24. A positioning rod 57 perpendicular to the crossbar 53 is horizontally provided on another upright 37. One end of the S-shaped locking rod 56 is separately movable and presses against the positioning rod 57. The positioning rod 57 prevents one end of the S-shaped locking rod 56 from reversing downwards too much. A stop rod 58 parallel to the positioning rod 57 is horizontally provided at the other end of the S-shaped locking rod 56. The side wall of the stop rod 58 is separately movable and contacts the end of the adjacent crossbar 53.

[0085] A collar 43 is provided at the top of the gantry frame 24. A limiting rod 44 is vertically inserted into the collar 43. The inner diameter of the collar 43 is larger than the outer diameter of the limiting rod 44. A limiting positioning rod 59 parallel to the positioning rod 57 is provided on the tension spring connecting rod 54. An extension rod 60 parallel to the horizontal rod 53 is fixed at the bottom of the vertical rod 52. The top of the extension rod 60 is placed between the two vertical rods 37 of the gantry frame 24. A limiting rod 61 parallel to the limiting positioning rod 59 is provided at the top of the extension rod 60.

[0086] The unlocking structure 27 includes an unlocking connecting rod 62, which is horizontally fixed between the two uprights 37 of the gantry frame 24. An unlocking collar 63 is provided on the unlocking connecting rod 62, and an unlocking rod 64 is vertically inserted into the unlocking collar 63. An unlocking crossbar 65 parallel to the crossbar 53 is horizontally provided on the side wall of the unlocking rod 64. A stop rod 58 is separately movable and presses on the unlocking crossbar 65. The stop rod 58 presses down on the unlocking crossbar 65 by its own weight. A crankshaft component 66 fixed to the long rod 26 is hinged to the bottom end of the unlocking rod 64.

[0087] An L-shaped reset rod 67 is provided on the long rod 26, and a reset push rod 68 parallel to the cross rod 53 is provided at the top of the L-shaped reset rod 67. The reset push rod 68 is in separate movable contact with the limit rod 44.

[0088] Working principle: In use, the overall principle of this embodiment is the same as that of embodiment 3. The difference is that the neck yoke 3 in this embodiment has three usage states, but the manifestations are different. The first state is to normally lock the animal's neck (e.g. Figure 19 As shown), when the animal's neck is inserted into the neck channel 6, it touches the bottom of the vertical bar 52 of the T-shaped frame 51 downwards. The T-shaped frame 51 rotates counterclockwise, and the horizontal bar 53 at the top of the T-shaped frame 51 moves along an arc-shaped trajectory. One end of the horizontal bar 53 first pushes the anti-reverse bar 58 upwards. The anti-reverse bar 58 rotates with the S-shaped locking bar 56. Then, the anti-reverse bar 58 descends by its own weight and blocks one end of the horizontal bar 53. The tension spring 42 cannot pull the T-shaped frame 41 to reset clockwise. The other end of the horizontal bar 53 rests horizontally at the top of the neck channel 6 to restrict the animal's neck from lifting, thus achieving the locking effect.

[0089] The second method is to unlock (such as...) Figure 15 (As shown), press down one end of the S-shaped locking bar 56, causing the stop bar 58 to lift up. The stop bar 58 is no longer pressing against the end of the crossbar 53. The tension spring 42 pulls the T-shaped frame 41 clockwise to reset, thus unlocking the neck yoke. This method can unlock a single neck yoke 3 individually. Alternatively, by rotating the long bar 26, the unlocking bar 64 can be raised within the unlocking collar 63, and the corresponding unlocking crossbar 65 can be used to lift the stop bar 58, also unlocking the neck yoke. This method can unlock the neck locking devices 25 of all neck yokes 3, facilitating the simultaneous release of all animals. It can also, when the stop bar 58 is pressing against the crossbar 53, block the limiting bar 61 with the limiting bar 44 corresponding to the animal that needs to be kept alone (e.g., ...). Figure 21 As shown), when the T-shaped frame 41 is unlocked and rotated, causing the extension rod 60 and the limiting rod 61 to move, the limiting rod 44 provides a reverse pull to the limiting rod 61, preventing the T-shaped frame 41 from being unlocked. The remaining animals can be unlocked, thus combining the functions of full unlocking and individual unlocking. It is convenient to use and widely applicable. If you want to unlock the limiting rod 44, you can continue to rotate the long rod 26, causing the L-shaped reset rod 67 and the reset push rod 68 to move towards the limiting rod 44. The reset push rod 68 pushes the limiting rod 44 open, allowing the T-shaped frame 41 to be unlocked, and the remaining animals are also unlocked.

[0090] The third method to prevent animals from accidentally entering the neck passage 6 (e.g.) Figure 17 As shown), the limiting rod 44 is adjusted to the other side of the limiting positioning rod 59. The limiting positioning rod 59 presses against the limiting rod 44. When the animal's neck touches the vertical rod 52 of the T-shaped frame 51 downwards, the extension rod 60 and the limiting rod 61 at the bottom of the vertical rod 52 move along the arc-shaped movement trajectory. The limiting positioning rod 59 provides reverse support to the limiting rod 44. The limiting rod 61 is blocked by the limiting rod 44 and cannot move. The horizontal bar 53 of the T-shaped frame 41 cannot push up the stop rod 58, so the T-shaped frame 41 is not locked by the stop rod 58, avoiding manual unlocking.

[0091] In Example 4, the unlocking operation of the S-shaped locking rod 56 is located at the top, making it convenient for workers to operate.

[0092] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
