Description

Technical Field

[0001] This utility model relates to the field of livestock feeding troughs for animal husbandry and veterinary use, and more specifically, it relates to a height-adjustable livestock feeding trough. Background Technology

[0002] Existing height-adjustable livestock feeder technology has several technical shortcomings, particularly in terms of feeder height adjustment and support. Current technologies typically employ a hydraulic drive system as the core power component for feeder height adjustment. This system uses hydraulic cylinders or lifting devices to move the feeder up and down to accommodate the different feeding height requirements of livestock at different growth stages. While this hydraulic drive method allows for flexible height adjustment, it presents significant safety and reliability issues in practical applications. Existing feeder lifting systems generally lack an effective automatic locking support structure. After the feeder is adjusted to the desired height, it relies solely on the pressure of the hydraulic components for support and fixation. If problems such as oil leakage, aging or failure of seals, or hydraulic pump malfunction occur during use, leading to a drop or complete loss of hydraulic pressure, the feeder will automatically fall due to the loss of hydraulic support. This sudden fall not only affects the normal feeding activities of livestock but may also frighten or cause mechanical injury to those feeding.

[0003] Furthermore, although some devices have technically attempted to achieve automatic locking and support functions for the feed trough through the cooperation of different components, these improved devices often have relatively simple locking and support structure designs, and the stability of the locking mechanism is often not strong enough. It is difficult to ensure that the feed trough can maintain a stable locking and support state for a long time after the height is adjusted. With the use of the feed trough, the locking and support components are prone to displacement or loosening due to the impact force generated by livestock and poultry eating on the feed trough, the vibration load during feed delivery, or other external forces in the breeding environment. This structural instability will cause the mechanism that was originally in the locking and support state to gradually fail, resulting in unexpected changes in the height of the feed trough or weakening of the support force. This not only affects the normal eating and feed utilization efficiency of livestock and poultry, but may also cause the feed trough to suddenly sink due to the failure of the locking and support, leading to safety accidents or affecting the normal operation of breeding.

[0007] The present invention is further configured such that a rolling wheel is rotatably mounted on one side of the locking block, and the rolling wheel is engaged between two adjacent locking blocks.

[0008] The present invention is further configured such that both sides of the outer wall of the braking block and both sides of the inner wall of the braking groove adopt a sloping structure design.

[0010] The present invention is further provided with multiple anti-slip strips fixedly provided on the outer sides of both the control sleeve and the limiting sleeve.

[0011] The present invention is further configured such that a plurality of locking rails are fixedly provided on one side of the control sleeve, and a locking groove is provided in the locking block, and the locking block slides outside the locking rail through the locking groove.

[0012] The present invention is further configured such that a connecting spring is movably provided on the inner side of the braking sleeve, and the two ends of the connecting spring are respectively connected to the inner wall of the braking sleeve and one side of the connecting block.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a highly adjustable livestock feeder, which has the following beneficial effects: 1. By setting up an automatic locking structure with inclined grooves, inclined plates, connecting blocks, braking blocks, and connecting springs, and by opening multiple braking grooves on the outside of the braking rod to cooperate with the braking blocks, the automatic locking support function after the feed trough is raised and lowered is realized. When the hydraulic cylinder drives the hydraulic rod to push the feed trough to a suitable height and then stops, the connecting spring will reset and push the connecting block to drive the inclined plate and braking block to slide, so that the corresponding braking block automatically locks into the corresponding braking groove. Through the cooperation of the braking block and the braking groove, an effective limit is formed on the braking rod, thereby realizing the locking support. This effectively solves the problem of the lack of an automatic locking support structure in the existing feed trough lifting system, avoids the safety hazard of relying solely on the pressure of the hydraulic components to maintain support after the feed trough is adjusted to the required height, and prevents the feed trough from automatically falling due to the loss of hydraulic support after the hydraulic pressure drops or is lost due to problems such as oil circuit leakage, aging and failure of seals, or hydraulic pump failure. This ensures the normal feeding activities of livestock and poultry, avoids the sudden drop of the feed trough from causing fright or mechanical injury to the livestock and poultry that are feeding, and improves the safety and reliability of livestock feed troughs.

[0014] 2. By setting up a stable structure with a locking block, locking rail, rolling wheel, and locking block, and by setting a limiting mechanism with a rotating plate, rotating hole, limiting sleeve, and push rod on the outside of the stopping sleeve, the structural stability of the trough in the locked support state is ensured. When the locking mechanism is adjusted and reset, the inner wall of the limiting sleeve will limit the outer wall of the rolling wheel, preventing the rolling wheel and locking block from sliding outward. At the same time, the locking block, through the cooperation of the rolling wheel and locking block, forms a limit, preventing the control sleeve from rotating accidentally. Furthermore, the push rod supports the limiting sleeve to one side of the rotating plate, preventing the limiting sleeve from sliding easily. Multiple components work together to form a multi-layered protection mechanism, effectively solving the problems of existing technologies. The design of the locking support structure is simple and lacks stability. It prevents the locking support components from shifting or loosening due to the impact force on the feed trough when livestock and poultry are eating, the vibration load when feed is being delivered, or other external forces in the breeding environment. This avoids the gradual failure of the mechanism that was originally in the locking support state, which would lead to unexpected changes in the height of the feed trough or a weakening of the support force. It ensures that the feed trough can maintain a stable locking support state for a long time, guaranteeing the normal feeding of livestock and poultry and the efficiency of feed utilization. It also prevents the feed trough from suddenly sinking due to the failure of the locking support, which could cause safety accidents or affect the normal operation of breeding.

A push spring 12 is movably fitted onto the outside of the push rod 11, and one end of the push spring 12 is connected to the limiting sleeve 10. Next, the other end of the push spring 12 abuts against one side of the rotating plate 7. The outer side of the stop sleeve 5 is slidably provided with a matching sleeve 13.

Multiple stop blocks 20 are fixed on one side of the connecting block 19. The stop blocks 20 are inserted into the stop groove 6. A pressure sleeve 21 is movably provided on one side of the stop block 20.

[0021] A hydraulic cylinder 22 is detachably mounted on the base frame 4. A hydraulic rod 23 is mounted on the output end of the hydraulic cylinder 22. The top end of the hydraulic rod 23 is detachably connected to the bottom end of the feeding trough 1. Telescopic sleeves 24 are detachably mounted at the four corners of the lower side of the top frame 2. Telescopic rods 25 are detachably mounted at the four corners of the upper side of the base frame 4. The telescopic sleeves 24 are slidably mounted on the outside of the telescopic rods 25.

[0022] In this embodiment, when it is necessary to unlock the state and lower the height of the feeding trough 1, firstly, rotate the rotating plate 7 in the forward direction, so that the rotating plate 7 drives the rotating hole 8 to rotate to a position concentric with the push rod 11. Then, push the limiting sleeve 10, so that the limiting sleeve 10 drives one side of the push rod 11 to gradually slide into the rotating hole 8 along the outer wall of the stopping sleeve 5. The limiting sleeve 10 and the rotating plate 7 will cooperate to squeeze the push spring 12 sleeved on the outside of the push rod 11. At the same time, the inner wall of the limiting sleeve 10 will gradually stop limiting the outer wall of the rolling wheel 26. Then, rotate the control sleeve in the forward direction. 9. The control sleeve 9 will drive multiple locking rails 30 on one side to rotate in the forward direction, and the locking rails 30 will drive multiple locking blocks 14 to rotate synchronously in the forward direction through the locking grooves 31. The locking blocks 14 will drive the rolling wheel 26 on one side to gradually roll out from between two adjacent locking blocks 17. Then the rolling wheel 26 will drive the locking block 14 on one side and the locking groove 31 opened in the locking block 14 to slide outward along the locking rail 30. The locking block 14 will drive the locking spring 15 to stretch outward. At the same time, due to the threaded connection between the inner wall of the control sleeve 9 and the outer wall of the adapter 13, and due to... The mating block 28 itself does not rotate. The fitting 13 then drives the mating block 28 to slide along the mating groove 27. The mating block 28 also drives the inner connecting pressure sleeve 21 to slide. The pressure sleeve 21 then pushes one side connecting block 19 to slide, causing the connecting block 19 to press against one side connecting spring 32. The connecting block 19 also drives one side inclined plate 18 to slide along the inclined groove 16, causing the inclined plate 18 to drive the connecting block 19 to slide outwards. Simultaneously, the connecting block 19 drives multiple... The stop block 20 moves, and due to the chamfered design of the outer wall of the stop block 20 and the inner wall of the stop groove 6, the stop block 20 will gradually be pulled out of the stop groove 6, so that the stop block 20 no longer limits the stop rod 3 through the stop groove 6. Then, the hydraulic cylinder 22 is driven in the opposite direction, so that the hydraulic cylinder 22 drives the hydraulic rod 23 to retract. Then the hydraulic rod 23 will drive the trough 1 to descend, so that the trough 1 drives the top frame 2 and the telescopic sleeve 24 to slide down along the telescopic rod 25. At the same time, the top frame 2 drives the stop rod 3 to slide down. When the height is adjusted to a suitable level, the hydraulic cylinder 22 can be closed.

[0023] Please see Figures 3-5 As a further implementation of the overall device: a rolling wheel 26 is rotatably installed on one side of the locking block 14, and the rolling wheel 26 is engaged between two adjacent locking blocks 17. Both sides of the outer wall of the braking block 20 and both sides of the inner wall of the braking groove 6 adopt a sloping structure design.

[0024] The side wall of the braking sleeve 5 is provided with a mating groove 27, and a mating block 28 is slidably provided in the mating groove 27. The inner wall of the fitting sleeve 13 is fixedly connected to the pressure sleeve 21 through the mating block 28.

[0025] Multiple anti-slip strips 29 are fixedly provided on the outer sides of both the control sleeve 9 and the limit sleeve 10.

[0026] Multiple locking rails 30 are fixedly provided on one side of the control sleeve 9, and a locking groove 31 is provided in the locking block 14. The locking block 14 slides outside the locking rail 30 through the locking groove 31.

[0027] A connecting spring 32 is movably provided on the inner side of the braking sleeve 5, and the two ends of the connecting spring 32 are respectively connected to the inner wall of the braking sleeve 5 and one side of the connecting block 19.

[0028] More specifically, when the height of the feeding trough 1 needs to be adjusted upwards, the pressure sleeve 21 and the matching sleeve 13, etc., must first be adjusted to their initial state, i.e., the locked state. First, the control sleeve 9 is rotated in the reverse direction, causing the control sleeve 9 to drive the one-sided locking rail 30 to rotate in the reverse direction and reset. The locking rail 30 will drive the locking block 14, the locking spring 15, and the rolling wheel 26 to rotate in the reverse direction and reset through the locking groove 31. At the same time, the control sleeve 9 will cooperate with the matching sleeve 13 through the thread, causing the matching sleeve 13 to drive the inner mating block 28 to rotate in the reverse direction and reset along the mating groove 27. The mating block 28 will drive the inner pressure sleeve 21 to slide in the reverse direction and reset. When the pressure sleeve 21 slides in the reverse direction and resets to its initial position, the locking block 14 and the rolling wheel 26 will just rotate in the reverse direction and reset. The locking spring 15 is positioned between the two original locking blocks 17, and then the locking block 14 is pulled back to its original position. This causes the locking block 14 to slide the locking groove 31 inward along the locking rail 30. At the same time, the locking block 14 will drive the rolling wheel 26 on one side to re-engage between the two original locking blocks 17. Then the limiting sleeve 10 is released, causing the push spring 12 to push the limiting sleeve 10 to slide back to its original position. Then the limiting sleeve 10 will drive the push rod 11 on one side to gradually slide back to its original position. When the push spring 12 is fully reset, the push rod 11 no longer passes through the rotating hole 8. Then the rotating plate 7 is rotated in the opposite direction, causing the rotating plate 7 to drive the rotating hole 8 to rotate back to a position that does not correspond to the push rod 11. Then the push rod 11 supports the limiting sleeve 10 on one side of the rotating plate 7, so that the limiting sleeve 10... 0 will not easily slide, and then the inner wall of the limiting sleeve 10 will again limit the outer wall of the rolling wheel 26, so that the rolling wheel 26 and the locking block 14 will not slide outward. Then the locking block 14, through the rolling wheel 26 and the locking block 17, forms a limit, so that the control sleeve 9 cannot rotate unexpectedly, ensuring the structural stability after the structure is reset. Then the forward drive hydraulic cylinder 22, and then the hydraulic cylinder 22 drives the hydraulic rod 23 to extend, so that the hydraulic rod 23 pushes the feeding trough 1 to rise. Then the feeding trough 1 drives the top frame 2 and the four telescopic sleeves 24 to gradually rise, while the telescopic sleeves 24 slide along the telescopic rod 25. At the same time, the top frame 2 will drive the stop rod 3 to rise. In this process, the stop rod 3 drives the stop groove 6 to slide. Due to the inner wall of the stop groove 6 and the outer wall of the stop block 20, The inclined plate design causes the inner wall of the braking groove 6 to press against the outer wall of the braking block 20, causing the braking block 20 and the connecting block 19 to slide the inclined plate 18 upwards. The inclined plate 18 also causes the braking block 20 and the connecting block 19 to slide outwards. Simultaneously, the connecting block 19 presses against the connecting spring 32, causing the braking block 20 to gradually slide out of the braking groove 6. When it reaches a suitable height, the hydraulic cylinder 22 is stopped, and the braking rod 3 moves the corresponding braking groove 6 to the corresponding position. At this time, the connecting spring 32 resets and pushes the connecting block 19, causing the connecting block 19 to slide the inclined plate 18 and the braking block 20 in the opposite direction to reset, so that the corresponding braking block 20 is engaged in the corresponding braking groove 6. Due to the limiting effect of the pressure sleeve 21 on the connecting block 19, the connecting block 19 cannot continue to slide downwards.Then, the braking block 20 and the braking slot 6 work together to limit the braking lever 3, thereby achieving the locking function and enabling autonomous support.

[0029] In summary, during the use or operation of the entire equipment: when it is necessary to unlock the device and lower the height of the feeding trough 1, first rotate the rotating plate 7 clockwise, causing the rotating plate 7 to drive the rotating hole 8 to rotate to a position concentric with the push rod 11. Then, push the limiting sleeve 10, causing the limiting sleeve 10 to slide along the outer wall of the stopping sleeve 5 and drive one side of the push rod 11 to gradually slide into the rotating hole 8. The limiting sleeve 10 and the rotating plate 7 will cooperate to compress the push spring 12 sleeved on the outside of the push rod 11. At the same time, the inner wall of the limiting sleeve 10 will gradually stop limiting the outer wall of the rolling wheel 26. Then, the device will rotate clockwise. Rotating the control sleeve 9 causes multiple locking rails 30 on one side to rotate in the forward direction. The locking rails 30, through locking grooves 31, drive multiple locking blocks 14 to rotate synchronously in the forward direction. The locking blocks 14 then cause a rolling wheel 26 on one side to gradually roll out from between two adjacent locking blocks 17. The rolling wheel 26 then causes the locking block 14 and the locking groove 31 in the locking block 14 to slide outward along the locking rail 30. The locking block 14 also causes the locking spring 15 to stretch outward. Simultaneously, due to the threaded connection between the inner wall of the control sleeve 9 and the outer wall of the adapter 13… Since the mating block 28 itself does not rotate, the fitting 13 will cause the mating block 28 to slide along the mating groove 27, and the mating block 28 will cause the inner connecting pressure sleeve 21 to slide. Then the pressure sleeve 21 will push the connecting block 19 on one side to slide, so that the connecting block 19 will press the connecting spring 32 on one side. The connecting block 19 will also cause the inclined plate 18 on one side to slide along the inclined groove 16, so that the inclined plate 18 will cause the connecting block 19 to slide outward. At the same time, the connecting block 19 will also cause the connecting spring 32 on one side to slide outward. Multiple stop blocks 20 move. Due to the chamfered design of the outer wall of the stop block 20 and the inner wall of the stop groove 6, the stop block 20 will gradually be pulled out of the stop groove 6, so that the stop block 20 no longer limits the stop rod 3 through the stop groove 6. Then, the hydraulic cylinder 22 is driven in the opposite direction, so that the hydraulic cylinder 22 drives the hydraulic rod 23 to retract. Then the hydraulic rod 23 will drive the trough 1 to descend, so that the trough 1 drives the top frame 2 and the telescopic sleeve 24 to slide down along the telescopic rod 25. At the same time, the top frame 2 drives the stop rod 3 to slide down. When the height is adjusted to a suitable level, the hydraulic cylinder 22 can be closed.

[0030] When the height of the feeding trough 1 needs to be adjusted upwards, the pressure sleeve 21 and the matching sleeve 13 should first be adjusted to their initial state, i.e., the locked state. First, rotate the control sleeve 9 in the reverse direction, causing the control sleeve 9 to drive the one-sided locking rail 30 to rotate in the reverse direction and reset. The locking rail 30 will drive the locking block 14, the locking spring 15, and the rolling wheel 26 to rotate in the reverse direction and reset through the locking groove 31. At the same time, the control sleeve 9 will cooperate with the matching sleeve 13 through the thread, causing the matching sleeve 13 to drive the inner mating block 28 to rotate in the reverse direction and reset along the mating groove 27. The mating block 28 will drive the inner pressure sleeve 21 to slide in the reverse direction and reset. When the pressure sleeve 21 slides back to its initial position, the locking block 14 and the rolling wheel 26 will just rotate back to their original positions. Between the two locking blocks 17, the locking spring 15 resets and pulls the locking block 14, causing the locking block 14 to drive the locking groove 31 to slide inward along the locking rail 30. At the same time, the locking block 14 will drive the rolling wheel 26 on one side to re-lock between the two locking blocks 17. Then the limiting sleeve 10 is released, causing the push spring 12 to push the limiting sleeve 10 to slide and reset. Then the limiting sleeve 10 will drive the push rod 11 on one side to gradually slide and reset. When the push spring 12 is fully reset, the push rod 11 no longer passes through the rotating hole 8. Then the rotating plate 7 is rotated in the opposite direction, causing the rotating plate 7 to drive the rotating hole 8 to rotate and reset to a position that does not correspond to the push rod 11. Then the push rod 11 supports the limiting sleeve 10 to one side of the rotating plate 7, so that the limiting sleeve 10 does not It will easily slide, and then the inner wall of the limiting sleeve 10 will again limit the outer wall of the rolling wheel 26, so that the rolling wheel 26 and the locking block 14 will not slide outward. Then the locking block 14, through the rolling wheel 26 and the locking block 17, forms a limit, so that the control sleeve 9 cannot rotate unexpectedly, ensuring the structural stability after the structure is reset. Then the forward drive hydraulic cylinder 22, and then the hydraulic cylinder 22 drives the hydraulic rod 23 to extend, so that the hydraulic rod 23 pushes the feeding trough 1 to rise. Then the feeding trough 1 drives the top frame 2 and the four telescopic sleeves 24 to gradually rise, while the telescopic sleeves 24 slide along the telescopic rod 25. At the same time, the top frame 2 will drive the stop rod 3 to rise. In this process, the stop rod 3 drives the stop groove 6 to slide. Due to the inclination of the inner wall of the stop groove 6 and the outer wall of the stop block 20, The slope design causes the inner wall of the braking groove 6 to press against the outer wall of the braking block 20, causing the braking block 20 and the connecting block 19 to slide the inclined plate 18 upwards. The inclined plate 18 also causes the braking block 20 and the connecting block 19 to slide outwards. Simultaneously, the connecting block 19 presses against the connecting spring 32, causing the braking block 20 to gradually slide out of the braking groove 6. When it rises to a suitable height, the hydraulic cylinder 22 is stopped, and the braking rod 3 moves the corresponding braking groove 6 to the corresponding position. At this time, the connecting spring 32 resets and pushes the connecting block 19, causing the connecting block 19 to slide the inclined plate 18 and the braking block 20 in the opposite direction to reset, so that the corresponding braking block 20 is engaged in the corresponding braking groove 6. Due to the limiting effect of the pressure sleeve 21 on the connecting block 19, the connecting block 19 cannot continue to slide downwards.Then, the braking block 20 and the braking slot 6 work together to limit the braking lever 3, thereby achieving the locking function and enabling autonomous support.
