Description

Technical Field

[0001] This utility model belongs to the technical field of livestock feed monitoring equipment structure, and in particular relates to a stock feed monitoring device. Background Technology

[0002] Feed quality plays a crucial role in the development of animal husbandry. It directly affects not only animal health and production performance but also the safety and economic benefits of livestock products. To promote the sustainable and healthy development of animal husbandry, it is necessary to strengthen the monitoring and management of feed quality to ensure feed safety, reduce waste, and guarantee supply.

[0003] In existing technologies, the main method for monitoring stockpiled feed is mechanical measurement combined with some sensors. However, this method is inefficient due to its complex installation and operation; it is also inaccurate because mechanical measurement uses a lot of instruments; and there is a delay in the data detected by different sensors, which prevents real-time monitoring. As a result, this monitoring method is difficult to meet the needs of industrialized farming.

[0004] More specifically, existing monitoring methods suffer from several drawbacks. First, mechanical gravity sensors used to measure feed inventory lack real-time monitoring capabilities and are prone to failure. Second, mechanical sensors monitoring the temperature and humidity of the feed storage environment are typically installed outside the feed silo, making it impossible to directly monitor the internal environment. Meanwhile, optical sensors installed inside the silo are highly sensitive to environmental changes, and their accuracy is significantly limited or even malfunctions in complex environments, such as rain, snow, freezing weather in northern regions, or dusty weather. Third, the method used to detect mold in feed involves sampling and testing only after mold is detected, which not only results in a delay but also makes it difficult to control the spread of mold in a timely manner.

[0017] 1. This feed inventory monitoring device employs a comprehensive structural design. First, a radar power component drives the lidar module's radar probe to rotate 360°, enabling a full-range scan of the feed inventory inside the feed tower and generating a precise 3D model.

The top of the first outer casing is fixedly connected to the lower part of the support bracket, and a temperature and humidity sensor is installed inside the first outer casing. This design ensures that the temperature and humidity sensor is unaffected by the complex external environment of the feed tower. Third, a rotating cover component installed inside the first outer casing automatically closes the opening at the bottom of the casing when it falls. Driven by an opening and closing power component, the cover rotates upwards, opening the bottom of the first outer casing. This design further reduces the influence of the feed tower's interior on the temperature and humidity sensor, improving the reliability of the monitoring device. In summary, this feed inventory monitoring device solves the problem that existing feed monitoring devices for livestock farming are insufficient to meet the needs of industrialized aquaculture.

[0018] 2. This feed monitoring device uses an odor sensor installed inside the second outer casing. An air pump draws air from the feed tower into the second outer casing, allowing for continuous monitoring of the feed inside the tower. Unlike existing technologies, which require sampling and testing only after mold is detected, this device effectively prevents the spread of mold and ensures that it can meet the needs of industrialized farming.

[0026] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0027] Please see Figures 1 to 5It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0028] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0029] Please see Figure 1 This utility model provides a feed inventory monitoring device 1 to solve the problem that existing feed inventory monitoring methods cannot meet the needs of industrialized farming. The structure of this monitoring device 1 will be described in detail below, and it includes:

[0030] like Figure 2 The bracket 11 shown has a hook 111 on its upper part, which is attached to the edge of the top cover of the material tower 3; the lower part of the bracket 11 extends into the interior of the material tower 3.

[0031] like Figure 2 The first outer casing 12 shown is fixedly connected to the top of the bracket 11 and has an opening at the bottom.

[0032] like Figure 3 As shown, the first outer casing 12 is equipped with a control module 13, a temperature and humidity sensor 14, and a lidar module 15. The lidar module 15 includes a downward-facing radar probe 151, which is driven by a radar power component 17 to rotate 360° with the rotation axis along the vertical direction.

[0033] like Figure 2 The cover plate component 16 shown is rotatably installed inside the first outer box 12 and automatically falls down to close the opening at the bottom of the first outer box 12; driven by the opening and closing power component 18, it rotates upward and opens the opening at the bottom of the first outer box 12.

[0034] like Figure 3 and Figure 4As shown, this feed inventory monitoring device 1 utilizes the design of the radar power component 17 driving the radar probe 1513 of the lidar module 15 to rotate 60°, enabling a comprehensive scan of the feed inventory inside the feed tower 3. The scanned data is transmitted to the control module 13, which integrates this data with the data transmitted by the temperature and humidity sensor 14 and transmits it to the cloud in real time. Algorithms on the cloud server perform calculations to generate a 3D model and, based on feed density and other information, calculate other necessary data, such as the weight of the feed inside the feed tower 3, and transmit this data to the user's mobile phone or computer, thus achieving real-time monitoring. Compared to the mechanical gravity sensor used in existing technologies, this lidar module 15 not only provides real-time monitoring of the feed inventory in the feed tower 3 but is also less prone to failure and offers more accurate measurements.

[0035] like Figure 2 As shown, the feed inventory monitoring device 1 is hung on the edge of the top cover of the feed tower 3 via a hook 111 on the upper part of the bracket 11, and extends to the interior of the feed tower 3. The top of the first outer box 12 is fixedly connected to the lower part of the bracket 11. The temperature and humidity sensor 14 is installed inside the first outer box 12. The cover plate component 16, which is rotatably installed inside the first outer box 12, closes the opening at the bottom of the first outer box 12 when it automatically falls down. Driven by the opening and closing power component 18, the opening at the bottom of the first outer box 12 is opened by rotating upward. This design ensures that the temperature and humidity sensor 14 is not affected by the complex external environment of the feed tower 3. Furthermore, because the cover plate component 16 can close the opening at the bottom of the first outer box 12 in a timely manner when the opening and closing power component 18 is not working, the influence of the temperature and humidity sensor 14 on the interior of the feed tower 3 is reduced, thus improving the working reliability of the monitoring device 1.

[0036] In summary, based on the above two points, this feed inventory monitoring device 1, through... Figures 2 to 4 The structural design shown solves the problem that the existing feed monitoring equipment 1 for livestock farming cannot meet the needs of industrialized breeding. In addition, the design of the hook 111 on the bracket 11 allows for installation without damaging the structure of the feed tower 3, eliminating the need for connection methods that would damage the feed tower 3, such as drilling, wiring, hoisting, and debugging. These details will not be elaborated here.

[0037] In another embodiment, the feed inventory monitoring device 1 further includes an odor sensor, an air pump, and a second outer casing. There are two brackets 11; the lower part of one bracket 11 is fixedly connected to the top of the first outer casing 12, and the lower part of the other bracket 11 is fixedly connected to the top of the second outer casing. The odor sensor is installed inside the second outer casing, and the air pump draws air from the feed tower 3 into the interior of the second outer casing. By designing the odor sensor in the separately designed second outer casing, compared with the existing technology that samples are only sent for testing after mold is detected in the feed, this device 1 solves the problem of delayed monitoring of mold and difficulty in controlling the spread of mold, further improving the adaptability of the feed inventory monitoring device 1 to industrialized livestock farming.

[0038] In another implementation, please refer to Figure 2 The lower part of the bracket 11 is fixedly connected to an inclined hanging plate 112, and the top of the first outer box 12 is provided with a sloping surface. The hanging plate 112 and the sloping surface are fitted together and fixedly connected. This fixed connection can be in the form of bolts for easy maintenance later. Specifically, the sloping surface at the top of the first outer box 12 can be a triangular top similar to an eave. The reason for this design is that when feed is conveyed from the top of the feed tower 3 into the feed tower 3, the feed can fall smoothly from the first outer box 12 without accumulating in large quantities. Even if a small amount of feed accumulates on the top of the first outer box 12, when the device 1 is started, the slight vibration of the device 1 itself will cause the small amount of feed accumulated on the top of the first outer box 12 to fall down, thereby ensuring the reliable operation of the entire feed storage monitoring device 1. At the same time, the design of the second outer box can also refer to the design of the first outer box 12, which will not be described in detail here.

[0039] In another implementation, please refer to Figure 2 The first outer casing 12 includes an upper casing 121 and a lower casing 122. The ramp surface is provided on the top of the upper casing 121. The bottom of the upper casing 121 is detachably connected to the top of the lower casing 122, so that the upper casing 121 can be closed and used as a second outer casing, which increases the versatility between the various components of this device 1. In addition, the design of the first outer casing 12 divided into an upper casing 121 and a lower casing 122 also facilitates subsequent maintenance after the modules inside the first outer casing 12 fail.

[0040] In another implementation, please refer to Figure 4The radar power component 17 includes a radar motor 171, a first gear 172, and a second gear 173. The lidar module 15 also includes a radar base 152. The radar motor 171 is fixedly installed inside the first outer casing 12. The first gear 172 is fixedly connected to the output shaft of the radar motor 171. The second gear 173 meshes with the first gear 172. The second gear 173 is fixedly connected to the radar base 152. The radar probe 151 is fixedly installed on the radar base 152. The working process of this structure will be described in detail below.

[0041] like Figure 4 As shown, the radar probe 151 is equipped with an infrared laser emitter and an infrared laser receiver. The infrared laser emitter outputs an infrared laser beam, which is reflected back after hitting an obstacle and captured by the infrared laser receiver. The timer inside the laser radar module 15 calculates the time from emission to return. Based on the speed and time of the infrared laser, the distance at which the laser emitted by the radar probe 151 reaches the feed inside the feed tower 3 can be obtained. Then, the output shaft of the radar motor 171 rotates, driving the first gear 172 to rotate. The second gear 173 rotates along with the first gear 172, thereby activating the radar base 1. When the radar probe 151 on the 52 rotates, the infrared laser emitter and receiver reach different positions, thus mapping multiple distances. This data is transmitted to the control module 13, which then integrates it and uploads it to the cloud. The cloud algorithm calculates the volume of feed in the feed tower 3 and obtains the weight of the feed using the principle of "volume * density = mass". The PLC controller and CPU integrated in the control module 13 are widely used in industrial control and will not be elaborated here. How the lidar module 15 calculates the volume of feed in the feed tower 3 based on multiple mapped distances is also widely used in surveying and mapping and will not be elaborated here. It should be noted that the design of meshing first gear 172 and second gear 173 is used to control the rotation of the radar probe 151. Compared to the radar motor 171 directly driving the radar probe 151, this design allows for more precise control of the radar probe 151's rotation position.

[0042] In another implementation, please refer to Figure 4 The second gear 173 and the radar base 152 are connected by a radar bearing. The radar bearing is rotatably mounted on the radar fixing plate 153. The radar fixing plate 153 is fixedly connected to the inner wall of the first outer casing 12. The design of the radar fixing plate 153 fully ensures the installation stability of the lidar module 15.

[0043] In another implementation, please refer to Figure 5The cover plate component 16 includes a left cover plate 161 and a right cover plate 162, both of which are rotatably mounted inside the first outer casing 12. The opening and closing power component 18 includes an opening and closing motor 181, a third gear 182, and a fourth gear 183. A fourth fixed shaft is fixedly mounted on one side of the output shaft of the opening and closing motor 181. The third gear 182 is fixedly connected to the output shaft of the opening and closing motor 181, and the fourth gear 183 is rotatably mounted on the fourth fixed shaft. The third gear 182 and the fourth gear 183 have the same module and number of teeth and mesh with each other. The left cover plate 161 and the right cover plate 162 rotate with the rotation of the fourth gear 183 and the third gear 182, respectively. A specific structural form of the opening and closing power component 18 is given here. Furthermore, the opening and closing power component 18 also includes a fifth gear. The fifth and sixth fixed shafts are also fixedly installed on one side of the output shaft of the opening and closing motor 181, including the wheel 184 and the sixth gear 185. The fifth gear 184 and the sixth gear 185 are rotatably mounted on the fifth fixed shaft and the sixth fixed shaft, respectively. The module and number of teeth of the fifth gear 184 and the sixth gear 185 are the same. The fourth gear 183 meshes with the fifth gear 184, the fifth gear 184 meshes with the sixth gear 185, and the sixth gear 185 meshes with the third gear 182. The left cover plate 161 is fixedly connected to the fifth gear 184, and the right cover plate 162 is fixedly connected to the sixth gear 185. This structure shows that when the opening and closing motor 181 is not working, the left cover plate 161 and the right cover plate 162 fall smoothly under their own weight, thereby closing the bottom opening of the first outer box 12.

[0044] In another implementation, please refer to Figure 5 Sealing strips 19 are installed at the connection points of the left cover plate 161, the right cover plate 162 and the first outer box 12 to ensure that the feed monitoring equipment 1 is in a closed state when not in operation, so as to achieve better dust prevention and improve the working reliability of the equipment 1.

[0045] In another implementation, please refer to Figure 2 The bracket 11 has a hollow design inside, which provides a layout for the internal wiring of the feed monitoring equipment 1, ensuring the concealment and safety of the wiring. In particular, the two key lines extending from the inside of the first outer box 12—the power line and the data line—can be extended to the outside of the feed tower 3 along these hollows, avoiding the lines being exposed inside the feed tower 3, achieving the purpose of moisture and corrosion prevention, and also avoiding possible damage to the lines during the feeding process.

[0046] In another implementation, please refer to Figure 3 and Figure 5A cleaning brush is fixedly installed on the inner side of the cover plate component 16. When the cover plate component 16 closes the opening at the bottom of the first outer box 12, the cleaning brush contacts the radar probe 151. The cleaning brush is an industrial cleaning brush that does not shed bristles. After the device 1 has finished working, the radar motor 171 can continue to operate after the cover plate component 16 closes the opening at the bottom of the first outer box 12, driving the radar probe 151 to rotate. The radar probe 151 makes slight contact with the cleaning brush inside the cover plate, realizing the self-cleaning function. After self-cleaning, due to the action of the sealing strip 19 of the cover plate component 16, the dust brushed off is effectively restricted at the sealing strip 19, that is, at the edge of the cover plate component 16. When the device 1 is started up again with slight vibration, this dust will be completely shaken off, ensuring the long-term stable operation of the device 1.

[0047] In other implementations, such as Figure 2 As shown, the opening and closing motor 181 is installed on the outside of the outer casing. The opening and closing motor 181 is fitted with a side casing 123. The separate arrangement of the opening and closing motor 181 and the radar motor 171 is beneficial for maintenance and replacement in the event of a failure of this device 1 in the future.

[0048] In summary, this utility model's stock feed monitoring device 1, through its overall structural design, firstly, uses a radar power component 17 to drive the radar probe 151 of the lidar module 15 to rotate 360°, enabling a comprehensive scan of the stock feed inside the feed tower 3 and generating an accurate three-dimensional model. This not only allows for real-time monitoring but is also unaffected by the external environment, providing accurate measurements and minimizing the risk of failure. Secondly, the device is attached to the edge of the feed tower 3's top cover via hooks 111 on the upper part of the bracket 11, extending downwards into the feed tower 3. The top of the first outer casing 12 is fixedly connected to the lower part of the bracket 11, and the temperature and humidity sensor 14 is installed on the first outer casing 12. The design of the outer casing 12 prevents the temperature and humidity sensor 14 from being affected by the complex external environment of the feed tower 3. A cover plate 16, rotatably mounted inside the first outer casing 12, automatically closes the opening at the bottom of the first outer casing 12 when it falls. Driven by the opening and closing power component 18, the opening at the bottom of the first outer casing 12 is opened by rotating upwards. This design reduces the influence of the feed tower 3 on the temperature and humidity sensor 14, improving the reliability of the monitoring device 1. In summary, the design of this feed monitoring device 1 solves the problem that existing feed monitoring devices for livestock farming cannot meet the needs of industrialized farming. Therefore, this utility model effectively overcomes the shortcomings of the prior art and has high industrial application value.

[0049] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
