Description

Technical Field

[0001] This invention relates to the field of pig farming technology, specifically to a quantitative feed dispensing device for pig farming. Background Technology

[0002] With the improvement of living standards, the demand for pork is increasing, and more and more pig farms are being put into use. With the development of technology, the pig farming industry is transforming from traditional pig farming to modern pig farming. Whether it is the breeding model, regional layout, production method, or production capacity, everything is changing.

[0003] Patent application CN202111327476.2 discloses a quantitative feed feeding device for pig farming, belonging to the field of pig farming technology. It includes a feed box, with its top plate connected to a feed pipe. A first inclined feed distribution plate is symmetrically arranged inside the feed pipe, supported by a support frame and dividing the feed pipe into two vertical channels. A symmetrical inclined baffle is arranged below the support frame, forming a transverse channel with the outer wall of the feed pipe. A partition is provided on the top plate of the feed box, with a discharge hole on the partition. The lower end of the transverse channel is connected to the discharge hole on the top plate of the partition. A movable sealing plate assembly is provided on the partition to seal the discharge hole. A second feed distribution plate is symmetrically arranged inside the feed box, dividing it into two feeding spaces. Movable door panels are provided on both sides of the feed box, with push rod assemblies on the inner side of the door panels that can open the movable sealing plate assembly to open the discharge hole on the partition.

[0004] Existing pig feed delivery equipment is typically used in centralized farming settings. However, in this environment, the feed requirements of each pig pen often differ. Relying solely on a central valve for unified feeding control makes it difficult to achieve quantitative feeding per pen. This is not conducive to the rational distribution of feed, the management of the uniformity of pig growth, or the overall improvement of farming efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a quantitative feed dispensing device for pig farming, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quantitative feed feeding device for pig farming, comprising a connecting pipe, a pull rod provided at the bottom of the connecting pipe, and a feeding mechanism fixedly connected to the outer wall of the connecting pipe; The feeding mechanism includes: The frame includes a connecting pipe whose outer wall is fixedly connected to the frame, a feeding pipe whose top is fixedly connected to the connecting pipe, a discharging pipe whose bottom is fixedly connected to the frame, a storage component whose inner wall is fixedly connected to the frame, a track whose top is fixedly connected to the frame, and a control component whose top is movably connected to the track. Feed inside the connecting pipe passes through the feeding pipe and storage component, and is finally discharged from the discharging pipe. By setting a feeding mechanism, the amount of feed fed can be controlled. When the feed reaches a preset capacity, the mechanism automatically cuts off the feeding, helping to ensure the accuracy of each batch's feeding amount, reducing the degree of manual intervention, and thus improving feeding efficiency and reliability. According to the above technical solution, the feed storage component includes two valves, which are respectively located at the top and bottom of the inner wall of the frame. A temporary storage tank is fixedly connected to the top of the bottom valve, and a feed pipe is fixedly connected to the bottom of the top valve. The temporary storage tank is fitted onto the outer wall of the feed pipe. A handle is fixedly connected to the front end of the two valves, and a groove is provided on the outer wall of the handle. The rotation of the handle is used to control the opening and closing of the valves. By setting up the feed storage component, the feed to be fed can be pre-stored in the temporary storage tank, which facilitates the adjustment and quantitative control of the feeding amount, improves the accuracy of feeding, helps to realize feeding management, reduces feed waste, and improves breeding efficiency. According to the above technical solution, the control component includes an inclined plate, the bottom of which is movably connected to a track. A third connecting plate is fixedly connected to the outer wall of the inclined plate, and a connecting frame is fixedly connected to the end of the third connecting plate away from the inclined plate. A third spring is fixedly connected to the inner wall of the connecting frame, and the end of the third spring away from the connecting frame is fixedly connected to a frame. The inner wall of the connecting frame is fixedly connected to a pulling rod. Pulling the pulling rod can move the inclined plate on the track. By setting up the control component, the opening operation of multiple valves in the feeding device can be realized by uniformly pulling the pulling rod, without the need to set up separate drive components for each mechanism. This simplifies the mechanical structure and control system, reduces the complexity and failure rate of the system, improves the overall reliability, helps to reduce the burden on the central control system, and reduces energy consumption and maintenance costs.

[0007] According to the above technical solution, a first connecting plate is fixedly connected to the inner wall of the frame, and a threaded column is provided on the inner wall of the first connecting plate. The outer wall of the threaded column is threadedly connected to the first connecting plate. A rotating disk is fixedly connected to the bottom of the threaded column, and a U-shaped plate is rotatably connected to the top of the threaded column through a bearing. A first connecting rod is fixedly connected to the end of the U-shaped plate away from the threaded column, and an annular plate is fixedly connected to the bottom of the first connecting rod. The rotating disk can drive the threaded column to rotate, thereby changing the height of the annular plate.

[0008] According to the above technical solution, an infrared device is fixedly connected to the top of the annular plate, a floating ring is provided at the bottom of the annular plate, and a hollow column is fixedly connected to the top of the floating ring. The hollow column slides through the annular plate and extends to the top of the annular plate. A blocking ring is fixedly connected to the outer wall of the top of the hollow column, and a vent is provided on the outer wall of the bottom of the hollow column. The infrared device can detect whether the floating ring is lifted. By setting up a feeding mechanism, the traditional method of direct sensor contact with feed is abandoned when detecting the internal feed volume. Considering that pig feed is mostly a liquid mixture with a certain degree of adhesion, it is easy to adhere and accumulate on the sensor surface during long-term use, which will lead to distortion of the detection signal and misjudgment. The use of non-contact detection can effectively avoid such problems, enhance the long-term stability and accuracy of detection, help ensure the continuous and reliable operation of the equipment, avoid feeding loss due to sensor contamination, and extend the maintenance cycle and service life of the equipment. According to the above technical solution, the frame is provided with connecting columns inside, and sliding columns are fixedly connected to both the upper and lower ends of the connecting columns. The ends of the two sliding columns away from the connecting columns are fixedly connected to the frame. Sliders are movably connected to the two sliding columns. Extension plates are fixedly connected to the outer walls of the two sliders. Force-bearing blocks are fixedly connected to the outer walls of the two sliders. The end of the extension plate away from the slider is movably connected to the slide groove. The change in the height of the slider can control the opening and closing of the valve.

[0009] According to the above technical solution, the inner wall of the force-bearing block is movably connected to a movable rod, the outer wall of the movable rod is connected to a protruding ring, the top of the protruding ring is connected to a second connecting plate, and the outer wall of the second connecting plate is rotatably connected to a force-bearing roller via a bearing. The movement of the control component can change the height of the slider through the force-bearing roller.

[0010] According to the above technical solution, a bracket is fixedly connected to the outer wall of the valve, a push rod is fixedly connected to the outer wall of the bracket, a first limiting plate is fixedly connected to the inner side of the bracket, a rotating plate is fixedly connected to the valve core away from the handle, a limiting groove is formed at the end of the rotating plate away from the valve, a second connecting rod is fixedly connected to the outer wall of the rotating plate, and a blocking plate is fixedly connected to the end of the second connecting rod away from the rotating plate. The first limiting plate and the blocking plate can limit the deflection angle of the handle.

[0011] According to the above technical solution, a sliding rod is movably connected to the inner wall of the bracket. A force-bearing plate is fixedly connected to the end of the sliding rod away from the valve. A second limiting plate is fixedly connected to the end of the sliding rod away from the force-bearing plate. A second spring is sleeved on the outer wall of the sliding rod. One end of the second spring is fixedly connected to the second limiting plate. The end of the second spring away from the second limiting plate is fixedly connected to the bracket. The end of the second limiting plate away from the second spring is provided with a protrusion conforming to the shape of the limiting groove. When the protrusion is embedded in the limiting groove, the angle of the handle can be locked.

[0012] Compared with the prior art, the present invention provides a quantitative feed dispensing device for pig farming, which has the following beneficial effects: 1. By setting up a storage component, the present invention can pre-store the feed to be fed in a temporary storage tank, which facilitates the adjustment and quantitative control of the feeding amount, improves the accuracy of feeding, helps to realize feeding management, reduces feed waste, and improves breeding efficiency. 2. By setting up a feeding mechanism, the present invention can control the amount of feed fed. When the feed reaches the preset capacity, the mechanism can automatically cut off the feeding, which helps to ensure the accuracy of the feeding amount for each batch, reduce the degree of manual intervention, and thus improve feeding efficiency and reliability. 3. By setting up a feeding mechanism, this invention eliminates the traditional method of direct sensor contact with feed when detecting internal feed volume. Considering that pig feed is mostly a liquid mixture with a certain degree of adhesion, it is easy to adhere and accumulate on the sensor surface during long-term use, which will lead to distortion of the detection signal and misjudgment. The non-contact detection method can effectively avoid such problems, enhance the long-term stability and accuracy of detection, help ensure the continuous and reliable operation of the equipment, avoid feeding loss due to sensor contamination, and extend the maintenance cycle and service life of the equipment. 4. By setting up a control component, the present invention can realize the opening operation of multiple valves in the feeding device by pulling the pull rod in a unified manner, without the need to set up drive components for each mechanism. This simplifies the mechanical structure and control system, reduces the complexity and failure rate of the system, improves the overall reliability, helps to reduce the burden on the central control system, and reduces energy consumption and maintenance costs.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0018] Example 1: See Figures 1-7 The present invention provides a technical solution: a quantitative feed feeding device for pig farming, including a connecting pipe 1, a pull rod 101 at the bottom of the connecting pipe 1, and a feeding mechanism 2 fixedly connected to the outer wall of the connecting pipe 1; The feeding mechanism 2 includes: a frame 201; the outer wall of the connecting pipe 1 is fixedly connected to the frame 201; a feeding pipe 202 is fixedly connected to the top of the frame 201, and the top of the feeding pipe 202 is fixedly connected to the connecting pipe 1; a discharge pipe 203 is fixedly connected to the bottom of the frame 201; a storage component 21 is fixedly connected to the inner wall of the frame 201; a track 204 is fixedly connected to the top of the frame 201; and a control component 22 is movably connected to the top of the track 204. The feed inside the connecting pipe 1 passes through the feeding pipe 202 and the storage component 21, and is finally discharged from the discharge pipe 203. A first connecting plate 205 is fixedly connected to the inner wall of the frame 201, and threaded posts 206 are provided on the inner wall of the first connecting plate 205. The outer wall of the threaded column 206 is threadedly connected to the first connecting plate 205. A rotating disk 207 is fixedly connected to the bottom of the threaded column 206. A U-shaped plate 208 is rotatably connected to the top of the threaded column 206 via a bearing. A first connecting rod 209 is fixedly connected to the end of the U-shaped plate 208 away from the threaded column 206. An annular plate 2010 is fixedly connected to the bottom of the first connecting rod 209. The rotating disk 207 can drive the threaded column 206 to rotate, thereby changing the height of the annular plate 2010. An infrared device 2011 is fixedly connected to the top of the annular plate 2010. A floating ring 2025 is provided at the bottom of the annular plate 2010. A hollow column 2012 is fixedly connected to the top of the floating ring 2025 and slides through the annular plate 2010. Extending to the top of the annular plate 2010, a blocking ring 2013 is fixedly connected to the outer wall of the top of the hollow column 2012, and a vent 2014 is opened on the outer wall of the bottom of the hollow column 2012. An infrared device 2011 can detect whether the floating ring 2025 is lifted. A connecting column 2015 is provided inside the frame 201, and sliding columns 2016 are fixedly connected to both the upper and lower ends of the connecting column 2015. The ends of the two sliding columns 2016 away from the connecting column 2015 are fixedly connected to the frame 201. Sliding blocks 2017 are movably connected to both sliding columns 2016. Extension plates 2019 are fixedly connected to the outer walls of both sliding blocks 2017, and force-bearing blocks 2020 are fixedly connected to the outer walls of both sliding blocks 2017. The end of the extension plate 2019 away from the slider 2017 is movably connected to the slide groove 215. The change in the height of the slider 2017 can control the opening and closing of the valve 211. The inner wall of the force block 2020 is movably connected to the movable rod 2021. The outer wall of the movable rod 2021 is connected to the height of the protruding ring 2022. The top of the protruding ring 2022 is connected to the height of the second connecting plate 2023. The outer wall of the second connecting plate 2023 is rotatably connected to the force roller 2024 through the bearing. The movement of the control component 22 can change the height of the slider 2017 through the force roller 2024. When feed needs to be fed, the feed enters through the connecting pipe 1 and is then transported to the storage component 21 inside the frame 201 through the feeding pipe 202.Rotating the rotating disk 207 causes the threaded column 206 to rotate within the first connecting plate 205. Since the threaded column 206 is threadedly connected to the first connecting plate 205, its rotational motion is converted into vertical movement. This, in turn, drives the annular plate 2010 to move up and down via the U-shaped plate 208 and the first connecting rod 209, thereby adjusting the height of the annular plate 2010 and setting the preset storage amount of feed in the storage assembly 21. As the connecting pipe 1 supplies feed, the feed in the storage assembly 21 gradually accumulates. When the feed reaches a certain level, it generates upward buoyancy on the floating ring 2025. The ventilation holes 2014 on the bottom outer wall of the hollow column 2012 allow gas to pass through, reducing resistance during floating. As the amount of feed increases, the floating ring 2025 is gradually lifted, causing the hollow column 2012 to slide upwards. When the infrared device 2011 detects the hollow column 2012, it indicates that the feed in the storage assembly 21 has reached the set amount.

[0019] Example 2: Please refer to Figures 8-12Based on Embodiment 1, the present invention provides a technical solution: the storage assembly 21 includes two valves 211, which are respectively located at the top and bottom of the inner wall of the frame 201. A temporary storage tank 212 is fixedly connected to the top of the bottom valve 211, and a discharge pipe 213 is fixedly connected to the bottom of the top valve 211. The temporary storage tank 212 is sleeved on the outer wall of the discharge pipe 213. A handle 214 is fixedly connected to the front end of the two valves 211. A groove 215 is formed on the outer wall of the handle 214. The rotation of the handle 214 is used to control the opening and closing of the valves 211. A bracket 216 is fixedly connected to the outer wall of the valves 211. A push rod 217 is fixedly connected to the outer wall of the bracket 216. The inner side of the bracket 216 is fixedly... A first limiting plate 218 is fixedly connected to the valve core of valve 211, with a rotating plate 219 fixedly connected to the end away from handle 214. A limiting groove 2110 begins at the end of the rotating plate 219 away from valve 211. A second connecting rod 2111 is fixedly connected to the outer wall of the rotating plate 219, and a blocking plate 2112 is fixedly connected to the end of the second connecting rod 2111 away from the rotating plate 219. The first limiting plate 218 and the blocking plate 2112 limit the deflection angle of handle 214. A sliding rod 2113 is movably connected to the inner wall of bracket 216. A force-bearing plate 2116 is fixedly connected to the end of the sliding rod 2113 away from valve 211, and a second limiting plate 2114 is fixedly connected to the end of the sliding rod 2113 away from force-bearing plate 2116. A second spring 2115 is sleeved on the outer wall of the rod 2113. One end of the second spring 2115 is fixedly connected to the second limiting plate 2114, and the other end of the second spring 2115 away from the second limiting plate 2114 is fixedly connected to the bracket 216. The end of the second limiting plate 2114 away from the second spring 2115 is provided with a protrusion conforming to the shape of the limiting groove 2110. When the protrusion is embedded in the limiting groove 2110, the angle of the handle 214 can be locked. During equipment operation, as feed is continuously supplied, the feed enters the temporary storage tank 212 through the upper valve 211 and the feed pipe 213. When the feed level in the temporary storage tank 212 rises to a preset height, the push rod 217 is triggered to push outward and then immediately reset (between the push rod 217 and the force plate 2116). (Maintaining only contact); the push rod 217 pushes the force plate 2116, causing the second limiting plate 2114 to disengage from the limiting groove 2110, thereby releasing the angle lock of the upper valve 211; then the first spring 2018 pushes the slider 2017 and the extension plate 2019 to move down, causing the handle 214 to deflect downward, closing the upper valve 211; the lower valve 211 performs the same operation (the downward deflection of the handle 214 in the upper valve 211 closes the valve, while the downward deflection of the handle 214 in the lower valve 211 opens the valve), thereby discharging the feed in the temporary storage tank 212; the whole process relies on the mechanical linkage and signal feedback of the mechanism itself to achieve closed-loop control, without relying on the central control system to transmit commands, and can complete all valve control.

[0020] Control component 22 includes an inclined plate 221, the bottom of which is movably connected to the track 204. A third connecting plate 222 is fixedly connected to the outer wall of the inclined plate 221. A connecting frame 223 is fixedly connected to the end of the third connecting plate 222 away from the inclined plate 221. A third spring 224 is fixedly connected to the inner wall of the connecting frame 223. The end of the third spring 224 away from the connecting frame 223 is fixedly connected to the frame 201. The inner wall of the connecting frame 223 is fixedly connected to a pull rod 101. Pulling the pull rod 101 can move the inclined plate 221 on the track 204. When feed feeding needs to be started, it is achieved by pulling the pull rod 101. The connecting frame 223 is moved synchronously by the pulling rod 101. The connecting frame 223 then moves the inclined plate 221 along the track 204 via the third connecting plate 222. The moving inclined plate 221 then squeezes the force roller 2024 to move upward. The upward force roller 2024 drives the protruding ring 2022 to move upward via the second connecting plate 2023 and the movable rod 2021. The protruding ring 2022 further drives the slider 2017 to move upward via the force block 2020, which in turn opens the upper valve 211 and allows the feed to enter the temporary storage tank 212. At the same time, the lower valve 211 closes to wait for the feed to gradually accumulate to the preset amount in the temporary storage tank 212.
