Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, specifically to a novel fertilizer spreader with monitoring function. Background Technology

[0002] Fertilizer spreaders are agricultural equipment used to evenly spread fertilizer. Their structure and working principle are designed around the core process of "fertilizer delivery - quantitative control - even spreading".

[0003] The main structural components of a fertilizer spreader include a fertilizer bin (hopper), a conveying mechanism, a metering control mechanism, a spreading device, a power and transmission system, and a walking and supporting mechanism. The fertilizer bin (hopper) stores the fertilizer to be spread (such as granular fertilizer or powdered fertilizer). The conveying mechanism transports the fertilizer from the hopper to the spreading device; common types include screw conveyors, scraper conveyors, and vibrating conveyors. The metering control mechanism adjusts the amount of fertilizer spread, mainly including an adjusting baffle and a speed regulating device. The adjusting baffle is located between the hopper and the conveying mechanism, controlling the amount of fertilizer falling by changing its height; the speed regulating device changes the amount of fertilizer conveyed per unit time by adjusting the speed of the conveying mechanism (such as a screw or scraper). The spreading device evenly spreads the delivered fertilizer onto the field; common forms include centrifugal spreading discs, oscillating tube spreaders, and pneumatic spreading devices. The power and transmission system includes a drive shaft, gearbox, chain or belt, etc., responsible for transmitting power to each working mechanism. The walking and support mechanism includes the frame, tires (or tracks), suspension system, etc.

[0004] In existing technologies, such as the utility model patent application number 202421717502.1, an automatic fertilizer spreading vehicle is proposed, which includes a frame and a controller, a hopper, a unloading mechanism, a fertilizer spreading mechanism, and a positioning device mounted on it. This solution obtains the frame position information through the positioning device, and the controller dynamically adjusts the travel route and unloading amount according to the position and the pre-applied fertilizer amount, reflecting a preliminary concept of automated control.

[0005] However, existing fertilizer spreader technologies, including those mentioned above, still share a common shortcoming: operators cannot monitor the remaining fertilizer level in the hopper or the operating status of the spreading device in real time from the cab. They must frequently get out of the vehicle to check manually or with assistance from others to obtain this information. This not only increases labor intensity but also affects the continuity and efficiency of fertilization operations. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a fertilizer spreader with monitoring capabilities. By integrating a video monitoring system, the operator can monitor the remaining fertilizer level in the hopper and the working status of the spreading device in real time from the cab, eliminating the need to frequently get out of the vehicle to check or rely on others for assistance, thus reducing labor intensity to a certain extent.

[0007] To solve the above problems, this utility model provides a fertilizer spreading vehicle with monitoring function, comprising:

[0008] A chassis with a driver's cab;

[0009] The hopper is mounted on the vehicle frame;

[0010] A conveying mechanism, located inside the hopper, is used to convey fertilizer from the hopper to the spreading device;

[0011] A spreading device is installed at the discharge port of the hopper to spread fertilizer evenly in the field.

[0012] A video monitoring unit is installed on the top of the cab to collect image information of the inside of the hopper and / or the working area of ​​the spreading device;

[0013] A display device is located in the driver's cab and is communicatively connected to the video monitoring component for displaying the image information in real time.

[0014] As a further improvement to the aforementioned fertilizer spreader with monitoring capabilities, the video monitoring component includes at least one waterproof and dustproof camera.

[0015] As a further improvement to the aforementioned fertilizer spreader with monitoring function, the camera is fixed to the top of the cab via an adjustable-angle mounting bracket.

[0016] As a further improvement to the aforementioned fertilizer spreader with monitoring capabilities, the camera is equipped with a supplementary light to provide illumination in low-light environments.

[0017] As a further improvement to the aforementioned fertilizer spreader with monitoring function, the display device is a touch-screen LCD display.

[0018] As a further improvement to the aforementioned fertilizer spreader with monitoring function, the touch-screen LCD display is integrated into the center console of the driver's cab.

[0019] As a further improvement to the aforementioned fertilizer spreader with monitoring function, the video monitoring component and the display device are connected via a wired connection, which may include a cable or a CAN bus.

[0020] As a further improvement to the aforementioned fertilizer spreader with monitoring function, the video monitoring component and the display device are connected wirelessly, including 4G / 5G, Wi-Fi, or Bluetooth communication modules.

[0021] As a further improvement to the aforementioned fertilizer spreader with monitoring capabilities, the video monitoring component also includes a wide-angle lens to expand the monitoring field of view.

[0022] As a further improvement to the aforementioned fertilizer spreader with monitoring function, the display device supports split-screen display, which can simultaneously display image information from multiple video monitoring components.

[0023] This utility model provides a fertilizer spreader with monitoring capabilities. By integrating a video monitoring system, the operator can monitor the remaining fertilizer level in the hopper and the working status of the spreading device in real time from the cab, eliminating the need for frequent exits or reliance on assistance, thus reducing labor intensity to some extent. Simultaneously, based on real-time monitoring of key components, the operator can promptly detect anomalies and proactively take control measures, effectively preventing issues such as missed or repeated application caused by fertilizer caking, delivery interruptions, or uneven spreading. This ensures the continuity and uniformity of the fertilization process, improving overall operational quality and efficiency, and providing reliable technical support for precision agriculture.

In the description of this utility model, it should be noted that unless otherwise expressly specified and limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] Please see Figure 1 As shown, an embodiment of this utility model provides a fertilizer spreading vehicle with monitoring function, including: a frame 20 with a driver's cab 10; a hopper 30 disposed on the frame 20; a conveying mechanism (not shown) disposed inside the hopper 30 for conveying fertilizer from the hopper 30 to a spreading device 40; a spreading device 40 disposed at the outlet of the hopper 30 for evenly spreading fertilizer to the field; a video monitoring component 50 disposed on the top of the driver's cab 10 for collecting image information of the inside of the hopper 30 and / or the working area of ​​the spreading device 40; and a display device (not shown) disposed inside the driver's cab 10 and communicatively connected to the video monitoring component 50 for displaying the image information in real time.

[0032] The fertilizer spreader with monitoring function provided in this embodiment of the utility model, through the integration of a video monitoring system, allows the operator to monitor the remaining fertilizer level in the hopper 30 and the working status of the spreading device 40 in real time from the cab 10, without having to frequently get out of the vehicle to check or rely on others for assistance, thus reducing labor intensity to a certain extent. Simultaneously, based on real-time monitoring of key components, the operator can promptly detect abnormalities and proactively take control measures, effectively preventing phenomena such as missed application or double application caused by fertilizer caking, conveying interruptions, or uneven spreading. This ensures the continuity and uniformity of the fertilization process, not only improving the overall quality and efficiency of the operation but also providing reliable technical support for achieving precision agriculture. It is understood that core components such as the hopper 30, conveying mechanism, and spreading device 40 can all be designed and selected based on existing mature mechanical structures and working principles. The improvement of this utility model lies in enhancing the overall intelligence level and operational convenience of the equipment through the innovative integration and application of the monitoring system.

[0033] In some embodiments of this invention, the video monitoring component 50 includes at least one waterproof and dustproof camera, which is fixed to the top of the cab 10 via an adjustable-angle mounting bracket. The use of a waterproof and dustproof camera, along with an adjustable-angle mounting bracket (not shown in the figure), ensures that the monitoring equipment can operate stably and reliably in harsh environments such as dusty, humid, and even rainy farmland, extending the equipment's lifespan. The adjustable bracket allows the camera angle to be flexibly adjusted according to actual needs to capture the best viewing angle inside the hopper 30 or the spreading area, reducing blind spots.

[0034] In some embodiments of this invention, the camera is equipped with a fill light (not shown in the figure) to provide illumination in low-light environments.

[0035] In some embodiments of this utility model, the display device is a touch-screen LCD display. The touch-screen LCD display is integrated into the central control panel of the cab 10. Using a touch-screen LCD display integrated into the central control panel provides the operator with a clear and intuitive human-machine interface. Touch operation simplifies function calls and setting processes, allowing the driver to conveniently view and operate the monitoring screen while focusing on driving. The integrated design maintains the neatness and aesthetics of the cab 10's interior, avoiding messy wires from external devices and potential collision interference, thus improving the operating experience and safety.

[0036] In some embodiments of this invention, the video surveillance component 50 is connected to the display device via a wired connection, which may include a cable or a CAN bus. Using a wired connection, such as a robust cable or a highly interference-resistant CAN bus, establishes a stable and reliable data transmission channel between the video surveillance component 50 and the display device.

[0037] In some embodiments of this invention, the video surveillance component 50 is wirelessly connected to the display device, including 4G / 5G, Wi-Fi, or Bluetooth communication modules. This wireless connection eliminates complex wiring, simplifies the vehicle installation process, and facilitates future equipment maintenance and upgrades. The wireless solution provides greater flexibility in device layout, allowing the display device or surveillance camera to be flexibly positioned within signal range. Furthermore, the use of 4G / 5G modules enables remote data transmission, providing functional expansion space for subsequent remote monitoring, data recording, and cloud platform management.

[0038] In some embodiments of this invention, an image processing unit (not shown in the figures) is also included, connected to the video monitoring component 50 and the display device, for recognizing and processing image information and displaying abnormal conditions on the display device. By adding the image processing unit, the system acquires intelligent recognition and diagnostic capabilities. This unit can automatically analyze the video stream and determine in real time whether the operation is normal, thereby freeing the operator from the fatigue of continuously focusing on the screen. When the system detects an anomaly, it can proactively issue a warning, transforming passive monitoring into proactive early warning, greatly improving the timeliness of problem detection and troubleshooting, and effectively preventing operation interruptions and fertilizer waste.

[0039] In some embodiments of this invention, the abnormal states include fertilizer clumping in the hopper 30, blockage of the conveying mechanism, or abnormal discharge from the spreading device 40. Clearly defining the specific types of abnormalities the system can intelligently identify, such as clumping, blockage, and abnormal discharge, makes its functions more targeted. This enables the fertilizer spreader to accurately monitor and warn of the most common and serious operational problems, helping operators quickly locate the root cause of the problem and take swift action to minimize downtime and ensure a smooth and efficient fertilization process.

[0040] In some embodiments of this invention, the video monitoring component 50 further includes a wide-angle lens (not shown) to expand the monitoring field of view. The application of the wide-angle lens significantly expands the monitoring field of view of a single camera, enabling it to cover a wider area. This means that fewer cameras can be used to monitor the entire hopper 30 or the overall working scene of the spreading device 40, reducing blind spots.

[0041] In some embodiments of this invention, the display device supports split-screen display, enabling simultaneous display of image information from multiple video monitoring components 50. The display device supports multi-screen split-screen display, allowing operators to simultaneously view real-time images from different monitoring points, such as inside the hopper 30 or on the left / right sides of the spreading device 40, on a single screen. It should be noted that split-screen display is a mature existing technology.

[0042] In summary, the fertilizer spreader with monitoring function provided by this utility model, through the integration of a video monitoring system, allows the operator to monitor the remaining fertilizer level in the hopper 30 and the working status of the spreading device 40 in real time from the cab 10, without having to frequently get out of the vehicle to check or rely on others for assistance, thus reducing labor intensity to a certain extent. Simultaneously, based on real-time monitoring of key components, the operator can promptly detect abnormalities and proactively take control measures, effectively preventing phenomena such as missed or repeated application caused by fertilizer caking, delivery interruptions, or uneven spreading. This ensures the continuity and uniformity of the fertilization process, not only improving the overall quality and efficiency of the operation but also providing reliable technical support for achieving precision agriculture.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
