Description

Technical Field

[0001] This utility model relates to the field of central feeding technology, and more specifically, to a displacement-type central feeding device with shock absorption function. Background Technology

[0002] With the development of industrial automation, the demand for precise and stable material supply in production is increasing. Displacement-type central feeding devices, through centralized feeding and automated control, achieve automatic material conveying, distribution, and metering, improving production efficiency and quality while reducing labor costs and intensity. This represents an inevitable trend in industrial automation. In the livestock industry, pelleted feed is widely used, and with the increasing demand for automation in the future, this device is expected to play a crucial role in the feed supply process, contributing to livestock automation. However, currently, farmers typically mix feed manually and transport it bucket by bucket to the feeding area, making the work extremely arduous and inefficient for livestock workers.

[0003] To address the aforementioned issues, current livestock farmers typically mix feed manually and transport it bucket by bucket to the feeding area. This feeding method is extremely labor-intensive and inefficient for the farmers. After extensive research, a central feeding device with patent publication number CN206442906U was found. This device includes a first shell and a second shell, both hollow structures. The top of the first shell and the bottom of the second shell are fixedly connected to the same connecting pipe, which communicates with the interiors of both shells. A water tank and a controller are fixedly connected to the top of the first shell, located on opposite sides of the second shell. A feeding funnel communicating with the interior of the second shell is fixedly fixed to the top of the second shell. In this invention, the multiple vacuum feed pumps and feed pipes enable multi-directional feed pumping; the drive motor and controller work together to ensure thorough mixing of the feed within the second housing; the combined use of the controller and corresponding structures saves feed mixing and feeding time for the feeder and improves their work efficiency; however, the technical solution provided by this patent has the following problems:

[0004] (1) According to the description of patent publication number CN206442906U, although the device has a stirring function and can fully stir the material, it is not equipped with a special scraping structure. In the process of stirring and conveying feed, after a large amount of material in the storage bin is conveyed out, a certain amount of material often remains on its inner wall. This residual material is difficult to clean thoroughly, which not only leads to the needless waste of material, but also may cause residual deterioration and bacterial growth in the long term, affecting the quality and hygiene of subsequent material stirring.

[0005] (2) The device will inevitably vibrate during operation. After the vibration is transmitted to the conveying pipeline, it will interfere with the normal flow of the material, causing the material to shake or pulse. For some production processes that require high material feeding accuracy, this will cause the material conveying amount to deviate, making it impossible to accurately control the material feeding amount, which will affect the product quality. For example, in the electronics or food industries, accurate material supply is crucial to product quality. The material feeding error caused by vibration may lead to product defects.

[0006] This invention enables the simultaneous operation of mixing materials and scraping off the material from the inner wall of the storage silo. This not only reduces waste caused by material residue, but also prevents the residue from deteriorating and breeding bacteria due to long-term accumulation, significantly improving the quality of subsequent material mixing and ensuring the hygiene of the mixing environment. Furthermore, it effectively improves the stability of the entire device structure, reduces the phenomenon of deviation in material delivery caused by vibration and inability to accurately control the material supply, thereby improving product quality.

[0020] Beneficial effects:

[0021] 1. By setting up a scraping component, after starting the motor of the scraping component, the motor drives the rotating disk to rotate through the rotating shaft. The rotating disk drives the scraper to rotate by the L-shaped rods fixedly connected to its two ends. During the rotation of the scraper, the material attached to the inner wall of the storage bin can be effectively removed. At the same time, the motor connected to the stirring paddle is started, so that the stirring paddle begins to stir the material in the storage bin. In this way, the device realizes the simultaneous operation of stirring the material and scraping the material on the inner wall of the storage bin. This not only reduces the waste caused by material residue, but also prevents the residual material from deteriorating and breeding bacteria due to long-term accumulation, significantly improving the quality of subsequent material stirring and ensuring the hygiene of the stirring environment.

[0022] 2. By setting up shock-absorbing components, if vertical vibration occurs during device operation, the vibration will be transmitted through the base plate, causing the shock-absorbing seat to move up and down. During this process, the support rod under the shock-absorbing seat will push the slider connected to it to slide. Because the slider is connected to the sliding spring, the sliding spring will continuously generate elastic force to resist the movement of the slider and absorb and convert vibration energy during the slider's movement, thus playing a shock-absorbing role. At the same time, the connecting rod inside the sleeve on the fixed block moves vertically under the action of the compression spring, further buffering the vertical vibration. Since both the horizontal and vertical shock-absorbing structures are arrayed with the geometric center of the base plate as the center, no matter which direction the base plate moves, at least one or even two sets of horizontal shock-absorbing structures will respond quickly and play a timely shock-absorbing role. The shock-absorbing functions in the two directions can work together to effectively improve the stability of the entire device structure, reduce the phenomenon of deviation in material conveying caused by vibration and inability to accurately control the feeding amount, thereby improving product quality.

[0023] 3. In summary, this type of displacement-type central feeding device with shock absorption function achieves simultaneous mixing of materials and scraping of materials from the inner wall of the storage silo. This not only reduces waste caused by material residue, but also prevents residual materials from deteriorating and breeding bacteria due to long-term accumulation, significantly improving the quality of subsequent material mixing and ensuring the hygiene of the mixing environment. The shock absorption component effectively improves the stability of the entire device structure, reducing deviations in material delivery caused by vibration and the inability to accurately control the feeding amount, thereby improving product quality.

Detailed Implementation

[0030] The following will refer to the appendix in the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0031] Please see Figure 1-5 In this embodiment of the present invention, a displacement-type central feeding device with shock absorption function includes a base plate 5 slidably connected inside a fixed frame 4, allowing the base plate 5 to slide relative to the fixed frame 4, providing space and a basis for the shock absorption components to function, facilitating the absorption of vibrations generated during device operation, and enhancing the stability of the device. A housing 2 is fixedly connected to the upper end of the base plate 5 via connecting columns, ensuring the stability of the material transmission and related structures within the housing 2. A storage bin 1 is located at the upper end of the housing 2, allowing materials in the storage bin 1 to smoothly enter the housing 2 through a connecting pipe 6 by gravity or other power, achieving orderly material transmission. A connecting pipe 6 is provided between the storage bin 1 and the housing 2, serving as a channel between the storage bin 1 and the housing 2. This allows materials to be stably transported from the storage bin 1 to the shell 2, realizing the material transfer function between different parts of the feeding device. The storage bin 1 is provided with a feed inlet 3 at one end, which facilitates the entry of materials from the outside into the storage bin 1. It is the entrance for materials to enter the feeding device. Its position design makes the operation of adding materials more convenient. The storage bin 1 is provided with a scraping component, which can scrape off the materials attached to the bin wall inside the storage bin 1, reducing material residue, improving material utilization, and improving the cleanliness inside the storage bin 1. A shock-absorbing component is provided between the fixed frame 4 and the base plate 5. The shock-absorbing component uses the relative position relationship between the two to reduce the impact of vibration on the entire device by buffering and absorbing vibration energy when the device is running, thereby improving the stability and reliability of the device operation.

[0032] The scraping assembly includes a rotating shaft 21 rotatably connected to the upper end of the storage bin 1, allowing the rotating shaft 21 to rotate on the storage bin 1. This provides support and a rotational foundation for the rotating shaft 21 to drive the rotation of other components, serving as the starting point for power transmission in the entire scraping assembly. A rotating disk 19 is fixedly connected to the lower end of the rotating shaft 21, ensuring that the rotation of the rotating shaft 21 is stably transmitted to the rotating disk 19, causing the rotating disk 19 to rotate along with the rotating shaft 21, achieving effective power transmission. L-shaped rods 20 are fixedly connected to the lower sides of the rotating disk 19, securely mounting the L-shaped rods 20 on the rotating disk 19. This allows the rotation of the rotating disk 19 to drive the L-shaped rods 20, which in turn drives the scraper 15 to rotate, achieving the scraping action on the inner wall of the storage bin 1. The outer sides of the L-shaped rods 20... A scraper 15 is fixedly installed so that it can rotate around the inner wall of the storage silo 1 under the drive of the L-shaped rod 20. The position design of the scraper 15 allows it to fit closely to the inner wall of the storage silo 1, effectively scraping off the material adhering to the silo wall and reducing material residue. The scraper 15 can be made of rubber. Rubber scrapers have good elasticity and can closely fit the shape of the inner wall of the storage tank to effectively scrape off residual material. The two ends of the rotating disk 19 are rotatably connected to the stirring paddle 14. This positional relationship allows the stirring paddle 14 to rotate below the rotating disk 19. When the rotating disk 19 rotates, the stirring paddle 14 can stir the material in the storage silo 1. In conjunction with the scraper 15, it realizes the dual functions of stirring the material and scraping off the material on the silo wall, improving the efficiency and quality of material processing in the storage silo 1.

[0033] The shock absorption assembly includes a groove 7 formed around the inner wall surface of the fixed frame 4, providing a sliding track for the base plate 5, allowing the base plate 5 to move vertically or horizontally within the fixed frame 4. This provides space for the movement of the base plate 5 during shock absorption, thereby achieving the shock absorption function. A shock absorption seat 8 is fixedly connected to the middle of the lower surface of the base plate 5, ensuring that the shock absorption seat 8 is securely installed on the base plate 5. This allows the vibration experienced by the base plate 5 to be effectively transmitted to the shock absorption seat 8, and then further absorbed by subsequent structures. A slide rod 10 is provided below the shock absorption seat 8, serving as a support and guide structure, providing a track for the sliding of the slider 11, and also reducing vibration. The vibration of the damping seat 8 is transmitted to the slider 11, which is slidably connected to the surface of the slide rod 10. The slider 11 can slide on the slide rod 10. When the damping seat 8 transmits vibration, the slider 11 can move on the slide rod 10, providing the necessary displacement conditions for the compression and tension of the damping spring. The damping seat 8 and the slider 11 are connected by a support rod 12 via a hinge. This allows the support rod 12 to change its angle with the relative movement of the damping seat 8 and the slider 11 when the base plate 5 vibrates, thus transmitting and dispersing the vibration force. It also provides the power source for the compression and tension of the sliding spring 13. The sliding spring 13, located between the fixed block 9 and the slider 11, absorbs and buffers vibration energy through compression and tension when the slider 11 is vibrated and slides on the sliding rod 10, reducing the impact of vibration on the base plate 5 and the entire device. The sleeve 17, fixedly connected to the upper surface of the fixed block 9, provides sliding space for the connecting rod 16 and ensures the smooth operation of the connecting rod 16. The vertical movement trajectory enables it to effectively transmit vibrations and perform shock absorption. The connecting rod 16 is slidably connected inside the sleeve 17. The connecting rod 16 can slide inside the sleeve 17. When the base plate 5 vibrates, the connecting rod 16 will move up and down inside the sleeve 17, thereby compressing or stretching the compression spring 18 to achieve buffering and absorption of vertical vibrations. The compression spring 18 is provided at the lower end of the connecting rod 16. When the connecting rod 16 is vibrated and moves up and down, the compression spring 18 absorbs the vertical vibration energy by compression and extension, further reducing the impact of vibration on the base plate 5 and the device, and improving the stability of the device.

[0034] In this embodiment of the utility model, the rotating shaft 21 passes through the upper end of the storage bin 1 and is rotatably connected to the upper end of the storage bin 1. This connection method provides a stable support point and rotation foundation for the rotating shaft 21, enabling the rotating shaft 21 to rotate flexibly on the storage bin 1. At the same time, it stabilizes the relative position between the rotating shaft 21 and the storage bin 1. The upper end of the rotating shaft 21 is fixedly connected to the output end of the motor, realizing the direct transmission of motor power to the rotating shaft 21. This ensures that the motor power can be transmitted to the rotating shaft 21 efficiently and stably, allowing the rotating shaft 21 to rotate according to the motor's operating speed and direction. The motor is fixedly installed on the upper surface of the storage bin 1, which ensures the stability of the motor during operation and reduces the impact of the motor's own vibration on other components.

[0035] In this embodiment of the present invention, a rotating disk 19 is fixedly connected to the lower end of the rotating shaft 21. This fixed connection method can stably transmit the rotational power of the rotating shaft 21 to the rotating disk 19, so that the rotating disk 19 can rotate synchronously with the rotating shaft 21, ensuring the stability and reliability of power transmission, and laying the foundation for driving the movement of other components. L-shaped rods 20 are fixedly connected to the lower surfaces on both sides of the rotating disk 19. The L-shaped rods 20 are firmly installed on the rotating disk 19, so that the rotating disk 19 can effectively drive the L-shaped rods 20 to rotate together when rotating. Then, the L-shaped rods 20 drive the scraper 15 to scrape the inner wall of the storage bin 1, realizing the function of the scraping component.

[0036] In this embodiment of the present invention, a scraper 15 is fixedly installed on the outer side of the L-shaped rod 20. This installation method allows the scraper 15 to be stably connected to the L-shaped rod 20, ensuring that the scraper 15 can rotate synchronously when the L-shaped rod 20 rotates with the rotating disk 19, thereby realizing the scraping action on the inner wall of the storage bin 1. The outer surface of the scraper 15 is in contact with the inner wall surface of the storage bin 1, so that the scraper 15 can closely contact the inner wall of the storage bin 1 during rotation, effectively scraping off the material attached to the bin wall, reducing material residue, improving material utilization, and also ensuring the cleanliness of the inside of the storage bin 1, preventing problems such as residual material deterioration and bacterial growth.

[0037] In this embodiment of the invention, the stirring paddle 14 is rotatably connected to both ends of the rotating disk 19. This connection method allows the stirring paddle 14 to rotate with the rotating disk 19 as support, ensuring the stability of the stirring paddle 14 during rotation. Furthermore, the rotating disk 19 provides a certain space and positional basis for the rotation of the stirring paddle 14, facilitating the stirring paddle 14's stirring operation on the materials in the storage silo 1. The stirring paddle 14 and scraper 15 are arranged alternately. This layout allows the stirring paddle 14 to stir the materials while the scraper 15 scrapes the materials from the inner wall of the storage silo 1 during the rotation of the rotating disk 19. The two work together to improve the processing efficiency of the materials in the storage silo 1, ensuring the uniformity of material stirring and reducing material residue on the silo wall. The upper end of the stirring paddle 14 is fixedly connected to the output end of the motor via a rotating shaft. The motor is fixedly installed on the upper surface of the rotating disk 19. This arrangement realizes the direct transmission of motor power to the stirring paddle 14, ensuring that the stirring paddle 14 can obtain a stable power source for rotation. Simultaneously, installing the motor on the rotating disk 19 makes the entire structure more compact.

[0038] In this embodiment of the present invention, a groove 7 is provided around the inner wall surface of the fixed frame 4, providing a track for the bottom plate 5 to slide up and down. This allows the bottom plate 5 to move up and down along the groove 7 within the fixed frame 4 when subjected to vibration, thus providing the necessary movement space for the operation of the shock-absorbing component. The bottom plate 5 slides up and down inside the groove 7. This sliding connection method allows the bottom plate 5 to transmit vibration to the shock-absorbing component, while also restricting the movement direction of the bottom plate 5, ensuring that it can move up and down stably during the shock absorption process without deviation or shaking, thus ensuring the stability and reliability of the shock absorption effect. A shock-absorbing seat 8 is fixedly connected to the middle position of the lower surface of the bottom plate 5, and the shock-absorbing seat 8 is firmly installed on the bottom plate 5, so that the vibration received by the bottom plate 5 can be effectively transmitted to the shock-absorbing seat 8, and then the other shock-absorbing components below the shock-absorbing seat 8 can perform shock absorption treatment, thereby enhancing the shock absorption capacity of the entire device.

[0039] In this embodiment of the invention, six slide rods 10 are provided below the shock-absorbing seat 8. The six slide rods 10 can provide sufficient support and buffering force to share the vibration received by the shock-absorbing seat 8. Compared with a smaller number of slide rods, they can more effectively absorb and disperse vibration energy, and improve the overall shock absorption effect of the device. The slide rods 10 are arranged in an array with the geometric center of the base plate 5 as the center. This distribution makes the force on the slide rods 10 under the base plate 5 more uniform. No matter which direction the base plate 5 vibrates, it can be ensured that at least some of the slide rods 10 will play a timely role in buffering and absorbing the vibration, thereby enhancing the stability of the device in all directions and avoiding tilting or damage to the device due to uneven force.

[0040] In this embodiment of the utility model, sliders 11 are slidably connected to the surface of the slide rod 10. The sliders 11 can slide freely on the slide rod 10. When the device vibrates and causes the shock absorber 8 to displace, the sliders 11 can move on the slide rod 10 to adapt to the movement of the shock absorber 8, providing a movable component base for subsequent vibration reduction. The shock absorber 8 and the sliders 11 are respectively connected by hinges to support rods 12. The hinge connection allows the support rods 12 to rotate flexibly. When the shock absorber 8 moves up and down due to vibration, the support rods 12 will push or pull the sliders 11 to slide on the slide rod 10, thereby transmitting the force generated by the vibration to the sliders 11. Then, the springs and other components connected to the sliders 11 are used to absorb and buffer the vibration energy, thereby realizing the vibration reduction function.

[0041] In this embodiment of the invention, one end of the slide rod 10 is fixedly connected to a fixing block 9. The fixing block 9 provides a stable support point for the slide rod 10, ensuring that the slide rod 10 remains stable during the operation of the device and will not shake or shift due to vibration or other factors, thus improving the stability of the entire shock absorption structure. The other end of the fixing block 9 is fixedly connected to the inner wall of the fixing frame 4. Through this connection method, the slide rod 10 and the fixing frame 4 are connected into a whole, allowing the shock absorption component to function with the help of the fixing frame 4. At the same time, the force generated during the shock absorption process is distributed to the fixing frame 4, enhancing the overall shock resistance of the device. The sliding springs 13 are respectively set between the fixed block 9 and the slider 11. When the slider 11 slides on the slide rod 10, the sliding springs 13 will be compressed or stretched. According to the characteristics of the spring, it will generate an elastic force opposite to the direction of movement of the slider 11, thereby absorbing and buffering the vibration energy and playing a role in shock absorption. The sliding springs 13 are respectively wrapped around the slide rod 10. The slide rod 10 provides a guiding role for the sliding springs 13, ensuring that the sliding springs 13 move along the direction of the slide rod 10 during compression and stretching, avoiding bending or deformation of the spring, so that the spring can work normally and stably play a role in shock absorption.

[0042] In this embodiment of the utility model, sleeves 17 are fixedly connected to the upper surface of the fixing block 9, so that the sleeves 17 have stable support and ensure that their position is fixed during the operation of the device. This provides a stable foundation for the subsequent sliding of the connecting rod 16 and the extension and retraction of the compression spring 18. The connecting rods 16 are slidably connected inside the sleeves 17. The connecting rods 16 can slide freely inside the sleeves 17. When the base plate 5 vibrates, the displacement generated by the vibration can be transmitted to the inside of the sleeves 17, which facilitates the subsequent shock absorption by the compression spring 18. The connecting rods 16 are fixedly connected to the lower surface of the base plate 5, ensuring that the vibration energy of the base plate 5 is directly transmitted to the connecting rods 16, so that the shock absorption component can respond to the vibration of the base plate 5 in a timely manner. Compression springs 18 are respectively provided between the lower end of the connecting rod 16 and the bottom end of the inner wall of the sleeve 17. When the connecting rod 16 slides inside the sleeve 17, the compression spring 18 will be compressed or stretched. The elastic potential energy of the spring is used to absorb and buffer the vibration energy transmitted from the base plate 5, thereby achieving effective shock absorption of the vertical vibration of the device.

[0043] Working principle: First, material is poured into storage silo 1 through feed inlet 3. Then, the motor of the scraping component is started. The motor drives the rotating disk 19 to rotate via a rotating shaft. The rotating disk 19, through L-shaped rods 20 fixedly connected to its two ends, drives the scraper 15 to rotate. During the rotation of the scraper 15, the material adhering to the inner wall of storage silo 1 can be effectively removed. At the same time, the motor connected to the stirring paddle 14 is started, so that the stirring paddle 14 begins to stir the material in storage silo 1. In this way, the device achieves the simultaneous operation of stirring the material and scraping the material from the inner wall of storage silo 1. This not only reduces waste caused by material residue, but also prevents the residual material from deteriorating and breeding bacteria due to long-term accumulation, significantly improving the quality of subsequent material stirring and ensuring the hygiene of the stirring environment. The stirred material enters the shell 2 through connecting pipe 6, and finally reaches the distribution system through displacement transmission. The distribution system will accurately distribute the material into the corresponding conveying pipes according to the needs of each processing equipment. If vertical vibration occurs during device operation... Vibration is transmitted through the base plate 5, causing the shock absorber 8 to move up and down. During this process, the support rod 12 under the shock absorber 8 pushes the slider 11 connected to it to slide. Because the slider 11 is connected to the sliding spring 13, the sliding spring 13 continuously generates elastic force to resist the movement of the slider 11 and absorb and convert vibration energy, thus playing a role in shock absorption. At the same time, inside the sleeve 17 located on the fixed block 9, the connecting rod 16 moves vertically under the action of the compression spring 18, further buffering the vertical vibration. Since the horizontal and vertical shock absorption structures are arranged in an array with the geometric center of the base plate 5 as the center, no matter which direction the base plate 5 moves, at least one or even two sets of horizontal shock absorption structures will respond quickly and play a timely role in shock absorption. The shock absorption functions in the two directions can work together to effectively improve the stability of the entire device structure, reduce the phenomenon of deviation in material conveying caused by vibration and inability to accurately control the feeding amount, thereby improving product quality.
