Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture technology, and more specifically, to a pig feed trough. Background Technology
[0002] In modern large-scale pig farming, scientific and reasonable feeding management is a key link to improve feed utilization and reduce breeding costs. As an important medium connecting feed and pigs, the functional design of feeding equipment directly affects feeding efficiency and feed waste. Currently, common feeding equipment on the market has obvious shortcomings in use, especially in the liquid feed feeding process. Operators cannot accurately control the feed flow according to the needs of pigs at different growth stages, resulting in uneven feed distribution, either too much feed causing waste or too little feed affecting the nutritional intake of pigs, making it difficult to achieve quantitative feeding.
[0003] During seasonal feeding adjustments and the raising of different breeds of pigs, the flowability and consistency of feed will vary significantly due to temperature changes and different formulations. This places higher demands on the adaptability of feeding equipment. Existing feeding devices lack effective flow regulation mechanisms and cannot quantitatively control liquid feeds of different consistencies. Operators often need to determine the appropriate feed amount through experience or multiple trials, which not only reduces work efficiency but also increases labor intensity. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] In view of the problems existing in the prior art, this utility model provides a pig feed trough to solve the technical problems mentioned in the background art.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a pig feed trough, comprising a trough body, with support plates fixedly provided on both sides of the trough body, and a feeding pipe fixedly provided on the support plates. A flow control mechanism is provided at the top of the feeding pipe, the flow control mechanism comprising a connecting sleeve and an adjusting sleeve, the connecting sleeve being fixedly located at the top of the feeding pipe, the adjusting sleeve rotating at the top of the connecting sleeve, an inner ring being fixedly provided on the inner side of the connecting sleeve, a transmission sleeve being fixedly provided on the inner side of the adjusting sleeve, a flow control sleeve being slidably provided on the inner side of the inner ring, a base plate being fixedly provided at the bottom end of the flow control sleeve, a screw being fixedly provided on the top surface of the base plate, the screw being threadedly connected to the transmission sleeve, and a flow passage hole being provided on the outer side of the flow control sleeve, the flow passage hole being provided in multiple sets distributed on the outer wall of the flow control sleeve.
[0008] The present invention is further configured such that a positioning block is slidably provided on the outer side of the adjusting sleeve, and multiple sets of positioning blocks are provided, each with a return spring connected to its top end. The bottom ends of the multiple sets of return springs are fixedly connected to the outer wall of the adjusting sleeve. A positioning groove is provided on the outer wall of the connecting sleeve, and multiple sets of positioning grooves are provided and distributed on the outer wall of the connecting sleeve, each abutting against the multiple sets of positioning blocks. This structural design forms a reliable automatic positioning mechanism. When the adjusting sleeve rotates to the appropriate position, the positioning block can automatically embed into the positioning groove under the action of the return spring, achieving precise position locking and ensuring that the flow rate will not change due to vibration or external force after adjustment.
[0009] The present invention is further configured such that a limiting sleeve is slidably provided on the outer wall of the connecting sleeve, the limiting sleeve abuts against the top of multiple positioning blocks, and a push spring is provided between the outer wall of the connecting sleeve and the limiting sleeve. This design forms a two-stage locking protection mechanism through the limiting sleeve and the push spring, so that the positioning blocks are firmly pressed into the positioning groove, which enhances the stability and reliability of positioning. At the same time, the elastic design of the push spring makes it easy for the operator to easily release the lock when adjustment is needed.
[0010] The present invention is further configured such that guide plates are fixedly provided between multiple sets of support plates. The guide plates are provided in multiple sets and are all inclined between the support plates. The multiple sets of inclined guide plates form a scientific feed distribution system, which enables liquid feed to be evenly distributed to all areas of the tank, avoiding local accumulation or lack, ensuring that all pigs can obtain feed fairly, and improving feed utilization.
[0011] The present invention is further configured such that an external connecting pipe is rotatably provided at the top of the adjusting sleeve. The rotatably provided external connecting pipe facilitates flexible connection with external feed conveying pipes of various specifications, enhancing the versatility and adaptability of the device. At the same time, it maintains the degree of freedom of rotation without affecting the adjustment function of the adjusting sleeve, realizing independent operation of feeding and adjustment functions.
[0012] The present invention is further configured such that a limiting rod is fixedly provided on the top surface of the base plate. The limiting rod is provided in multiple sets and is slidably connected to the inner ring. The sliding connection design of multiple sets of limiting rods with the inner ring ensures that the base plate and the flow control sleeve move smoothly along the predetermined trajectory during the adjustment process, preventing deflection or jamming, improving the accuracy and smoothness of the adjustment process, and extending the service life of the device.
[0013] The present invention is further provided with a guide strip on the outside of the connecting sleeve. Multiple sets of the guide strip are provided and all are slidably connected to the limiting sleeve. The slidable connection design between the guide strip and the limiting sleeve ensures that the limiting sleeve can only move along the axial direction without rotation, making the push-pull operation smoother and more reliable. It also enhances the stability of the limiting function and reduces the possibility of misoperation.
[0014] The present invention is further configured such that both ends of the multiple sets of positioning blocks are rounded, and the top of the limiting sleeve is rounded. The rounded and rounded designs reduce friction and impact between components, making the process of the positioning blocks entering and leaving the positioning groove smoother, reducing wear on parts, improving the operating feel and durability of the device.
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, the present invention provides a pig feed trough, which has the following beneficial effects:
[0017] 1. The pig feed trough provided by this utility model features an innovative flow control mechanism. By fixing the connecting sleeve to the top of the feeding pipe and the clever cooperation between the rotatable adjusting sleeve and the internal structure, the flow rate of liquid feed can be adjusted. This solves the problem in the prior art that it is impossible to accurately control the feed flow rate according to the different growth stages of pigs. The operator only needs to rotate the adjusting sleeve to drive the transmission sleeve to engage with the screw, which will drive the bottom plate to move and drive the flow control sleeve to slide, thereby changing the overlap area between the flow hole and the inner ring, accurately controlling the flow area and flow rate of the feed, and meeting the actual needs of precision feeding.
[0018] 2. This device is designed with a complete positioning and limiting system. Multiple sets of elastically reset positioning blocks are set on the outside of the adjusting sleeve to cooperate with the positioning groove on the outer wall of the connecting sleeve. At the same time, a combination structure of limiting sleeve and push spring is used to achieve stable locking. This ensures that the adjusted flow setting can remain stable and will not change due to vibration or external force, thus ensuring the consistency and reliability of feed feeding. When readjustment is required, simply push the limiting sleeve to release the abutment of the positioning block. The positioning block will disengage from the positioning groove through the action of the reset spring, allowing for quick and convenient new flow adjustment. This greatly improves the convenience of operation and work efficiency.
[0019] 3. This utility model also forms a scientific feed distribution system by setting multiple sets of inclined guide plates between the support plates, so that the liquid feed can be evenly distributed in all areas of the tank, avoiding the problem of excessive or insufficient feed in some areas. At the same time, the sliding connection design of multiple sets of limiting rods on the top surface of the bottom plate with the inner ring ensures the stable movement of the flow control sleeve during the adjustment process without deflection. Combined with the rounded corner design of the end of the arc-shaped positioning block and the top of the limiting sleeve, the wear between components is reduced and the smoothness of operation is improved. The whole system constitutes a complete, easy-to-operate, and highly adaptable feed dispensing control system, which effectively solves the problem of difficult feed flow adjustment in the prior art and meets the precise control requirements of feeds with different consistencies.

[0029] Please see Figures 1-5 A pig feed trough includes a trough body 1, with support plates 2 fixedly installed on both sides of the trough body 1. A feeding pipe 3 is fixedly installed on the support plates 2. A metering control mechanism is installed at the top of the feeding pipe 3. The metering control mechanism includes a connecting sleeve 4 and an adjusting sleeve 5. The connecting sleeve 4 is fixedly installed at the top of the feeding pipe 3, and the adjusting sleeve 5 rotates at the top of the connecting sleeve 4. An inner ring 6 is fixedly installed inside the connecting sleeve 4, and a transmission sleeve 7 is fixedly installed inside the adjusting sleeve 5. A flow control sleeve 8 is slidably installed inside the inner ring 6. A base plate 9 is fixedly installed at the bottom of the flow control sleeve 8, and a screw 10 is fixedly installed on the top surface of the base plate 9. The screw 10 is threadedly connected to the transmission sleeve 7. A flow passage hole 11 is opened on the outer side of the flow control sleeve 8, and multiple sets of flow passage holes 11 are distributed on the outer wall of the flow control sleeve 8.
[0030] The adjusting sleeve 5 is slidably provided with a positioning block 12. Multiple positioning blocks 12 are provided, and each of them is connected to a return spring 13 at its top. The bottom ends of the multiple sets of return springs 13 are fixedly connected to the outer wall of the adjusting sleeve 5. The outer wall of the connecting sleeve 4 is provided with a positioning groove 14. Multiple positioning grooves 14 are provided and distributed on the outer wall of the connecting sleeve 4 and respectively abut against the multiple sets of positioning blocks 12. Under the action of the return spring 13, the positioning block 12 can automatically embed into the positioning groove 14. When the adjusting sleeve 5 is rotated to the desired position, the positioning block 12 and the positioning groove 14 engage to form a mechanical lock, thereby achieving precise positioning and fixing of the adjusting sleeve 5.
[0031] A limiting sleeve 15 is slidably provided on the outer wall of the connecting sleeve 4. The limiting sleeve 15 abuts against the top of multiple positioning blocks 12. A push spring 16 is provided between the outer wall of the connecting sleeve 4 and the limiting sleeve 15. The push spring 16 pushes the limiting sleeve 15 downward to press the positioning block 12, increasing the contact pressure between the positioning block 12 and the positioning groove 14, forming a double locking mechanism to ensure that the adjusted position is stable and reliable.
[0032] A guide plate 17 is fixed between multiple sets of support plates 2. The guide plate 17 is provided in multiple sets and is inclined between the support plates 2. The inclined guide plate 17 uses the principle of gravity to evenly disperse the feed flowing in to different areas, prevent local accumulation, and ensure that the feed is evenly distributed in the tank 1.
[0033] The top of the adjusting sleeve 5 is rotatably equipped with an external pipe 18. The external pipe 18 adopts a rotatable connection method, which can realize flexible docking with the external feed conveying pipe, while not affecting the rotation adjustment function of the adjusting sleeve 5, making it convenient for operators to connect the feed and control the flow.
[0034] A limiting rod 19 is fixedly provided on the top surface of the base plate 9. Multiple sets of limiting rods 19 are provided and all are slidably connected to the inner ring 6. The sliding cooperation of the limiting rod 19 in the inner ring 6 ensures that the base plate 9 and the flow control sleeve 8 can only move axially without deflection, thus ensuring the precise alignment between the flow hole 11 and the inner ring 6.
[0035] The outer side of the connecting sleeve 4 is provided with a guide bar 20. Multiple sets of guide bars 20 are provided, and all of them are slidably connected to the limiting sleeve 15. The guide bar 20 restricts the limiting sleeve 15 to move only along the axis and not rotate through the sliding cooperation with the limiting sleeve 15, so as to ensure that the limiting sleeve 15 can stably and reliably perform the locking and unlocking functions.
[0036] The multiple positioning blocks 12 are all rounded at both ends, and the top of the limiting sleeve 15 is rounded. The rounded and rounded design makes the surfaces of the contacting parts smooth, reduces stress concentration and frictional resistance, and makes the process of the positioning blocks 12 entering and exiting the positioning groove 14 smoother, improving operating comfort and extending the service life of the parts.
[0037] In this embodiment, during use, the external pipe 18 is connected to the external feed conveying pipe, and the feed is injected into the tank 1 through the feed pipe 3. When it is necessary to adjust the feed injection flow rate, the rotating adjustment sleeve 5 drives the transmission sleeve 7 to rotate. The transmission sleeve 7 is threadedly engaged with the screw 10, so that the screw 10 drives the bottom plate 9 to move. The bottom plate 9 slides along the inner ring 6 through multiple sets of limiting rods 19, and at the same time drives the flow control sleeve 8 to slide along the inner ring 6, thereby adjusting the blocking area of multiple sets of flow holes 11 by the inner ring 6, thereby adjusting the flow area of the feed, and thus adjusting the feed flow rate. The push spring 16 pushes the limiting sleeve 15 to abut against the top of multiple sets of positioning blocks 12, so that the bottom of multiple sets of positioning blocks 12 abuts against the positioning groove 14 and compresses multiple sets of return springs 13, thereby completing the positioning of the adjustment sleeve 5.
[0038] More specifically, the push limit sleeve 15 releases the contact with the multiple sets of positioning blocks 12 and squeezes the push spring 16, thereby releasing the contact with the multiple sets of positioning blocks 12. The multiple sets of reset springs 13 pull the multiple sets of positioning blocks 12 so that their bottom ends are disengaged from the positioning groove 14, releasing the positioning of the adjustment sleeve 5. Then, the adjustment can be performed again.
[0039] In summary, during use or operation of the overall equipment: When in use, connect the external pipe 18 to the external feed delivery pipe, and inject feed into the tank 1 through the feed pipe 3. When it is necessary to adjust the feed injection flow rate, rotate the adjusting sleeve 5 to drive the transmission sleeve 7 to rotate. The transmission sleeve 7 is threadedly engaged with the screw 10, causing the screw 10 to move the base plate 9. The base plate 9 slides along the inner ring 6 via multiple sets of limiting rods 19, simultaneously driving the flow control sleeve 8 to slide along the inner ring 6, thereby adjusting the blocking area of multiple sets of flow holes 11 by the inner ring 6, thus adjusting the feed flow area and regulating the feed flow rate. The push spring 16 pushes the limiting sleeve 15 to abut against the top of multiple sets of positioning blocks 12, causing the bottom of the multiple sets of positioning blocks 12 to abut against the positioning groove 14 and compressing the multiple sets of return springs 13, thereby completing the positioning of the adjusting sleeve 5.
[0040] Push the limiting sleeve 15 to release the contact with the multiple sets of positioning blocks 12 and squeeze the push spring 16, thereby releasing the contact with the multiple sets of positioning blocks 12. Then, pull the multiple sets of positioning blocks 12 with the multiple sets of reset springs 13 to make their bottom ends disengage from the positioning groove 14, releasing the positioning of the adjusting sleeve 5, and then adjustment can be performed again.
