Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to an organic fertilizer spreading vehicle which combines a broadcasting fertilization mode with a dumping fertilization mode. Background Art

[0002] With the development of modern agriculture, organic fertilizers and soil conditioners play an increasingly important role in soil improvement. Organic fertilizers such as pig manure and cow manure are widely used because of their rich nutrients and significant effects on soil improvement. At the same time, substances such as lime and soil conditioners can effectively adjust the pH and structure of the soil and increase the growth and yield of crops.

[0003] However, traditional fertilization equipment generally has several technical bottlenecks: (1) Traditional equipment can only handle a single type of fertilizer. When faced with wet and heavy organic fertilizers such as pig manure and cow manure, it is easy to get blocked or transported poorly. For lighter, fine-grained lime and soil conditioners, they are prone to uneven distribution when spread. (2) Poor manure and adaptability: When working in farmland, especially in complex or slippery terrain, traditional four-wheel fertilizer spreaders are prone to getting stuck or difficult to turn effectively due to their large size and lack of maneuverability, resulting in low operating efficiency. (3) Rapid equipment wear and tear: Organic fertilizers, especially pig manure and cow manure, contain high humidity and corrosive components. Traditional fertilizer spreading equipment lacks effective anti-corrosion design, resulting in easy wear and tear of the equipment and a short service life, which increases farmers' maintenance costs.

[0004] In view of the above problems, there is an urgent need for a fertilizer application device with strong power, good maneuverability, adaptability to various fertilizer types and strong durability. In view of these problems, the present invention proposes a multifunctional fertilizer application vehicle with a three-wheel chassis design, which can adapt to different terrains and fertilizer types and improve the efficiency and effect of fertilization operations. Summary of the invention

[0005] To solve the above problems, the present invention provides an organic fertilizer spreading vehicle that combines broadcasting and dumping fertilization modes, which provides strong support for agricultural production through dual-mode fertilization functions (broadcasting and dumping) and a highly automated control system.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: an organic fertilizer fertilizing vehicle combining a broadcasting type and a dumping type fertilizing dual mode, comprising a three-wheel chassis structure, a driving assembly installed at the bottom of the three-wheel chassis structure, a storage bin for storing organic fertilizer and materials installed on the top of the three-wheel chassis structure, a stirring assembly installed in the storage bin, the stirring assembly comprising a first power member, an output shaft of the first power member is coaxially fixedly connected to a screw rod, a nut seat is sleeved on the screw rod, the nut seat and the screw rod form a ball screw structure, a plurality of stirring shafts are fixedly connected to the outer side wall of the nut seat, and a scraper is fixedly connected to one end of the stirring shaft away from the nut seat; A spreading structure and a dumping structure are also installed on the top of the three-wheel chassis structure. A conveying assembly is installed between the storage bin and the spreading structure. The input end of the conveying assembly is connected to the storage bin, and the output end of the conveying assembly is connected to the spreading structure. The first power member is signal-connected to a controller, and the controller is integrated with an artificial intelligence algorithm module. The artificial intelligence algorithm module has a built-in convolutional neural network model, which is used to generate a dynamic fertilization strategy through correlation analysis between historical fertilization data and crop yield; The controller signal is connected with the soil moisture sensor and the GPS positioning sensor. The controller uses the artificial intelligence algorithm module to connect the soil moisture data and location information monitored in real time by the soil moisture sensor and the GPS positioning sensor with the crop growth database signal, so as to automatically optimize the sowing speed, angle and fertilizer ratio according to the real-time soil data and the crop growth stage. The controller is connected to the drive component, the spreading structure, the dumping structure and the conveying component by signal. The controller is used to control the spreading speed and spreading angle of the spreading structure, and to control the dumping angle and flow rate of the fertilizer in the dumping structure. At the same time, the controller is used to switch the spreading structure and the dumping structure. The controller is also used to control the fertilizer conveying speed of the conveying component.

[0007] The technical principle of the above scheme is as follows: the fertilizer vehicle adopts a three-wheel chassis structure, and a drive assembly is installed at the bottom to provide strong power support. This design makes the fertilizer vehicle have good maneuverability and stability, especially suitable for complex terrains such as farmland and orchards. The storage bin is located on the top of the vehicle body and is used to store organic fertilizer and materials. The stirring assembly includes a first power member (such as a motor or hydraulic motor), a screw rod, a nut seat and a stirring shaft. The first power member drives the screw rod to rotate, and the nut seat moves on the screw rod, driving the stirring shaft and the scraper to stir the fertilizer in the storage bin to prevent the fertilizer from agglomerating or piling up, and ensure the uniformity and smoothness of the fertilizer transportation. The conveying assembly connects the storage bin and the sowing structure, and is used to transport the fertilizer from the storage bin to the sowing structure. Its conveying speed can be precisely adjusted by the controller.

[0008] The spreading structure and dumping structure are used to achieve broadcasting and dumping fertilization respectively. The spreading structure may include components such as fertilizer spreaders and nozzles, which spread fertilizers evenly in the field through rotation or airflow. The dumping structure quickly releases fertilizers through the dumping port to cover a larger fertilization range. The controller can automatically switch between the spreading structure and the dumping structure according to the operation requirements. As the "brain" of the entire fertilizer spreader, the controller is responsible for receiving operation instructions and controlling the coordinated work of various components. Through the controller, the operator can easily adjust parameters such as spreading speed, spreading angle, fertilizer dumping angle and flow rate to achieve precise fertilization. At the same time, the controller is not only responsible for controlling the various functions of the fertilizer spreader, but also integrates advanced artificial intelligence algorithm modules. The module has a built-in convolutional neural network model, which uses a deep learning algorithm to correlate historical fertilization data with crop yields, so as to generate a dynamic fertilization strategy. This means that the fertilizer spreader can automatically optimize the fertilization plan according to the growth needs of different crops, current soil moisture and geographical location information.

[0009] Specifically, the soil moisture sensor monitors the moisture content in the soil in real time, while the GPS positioning sensor records the location information of the fertilizer truck. This information is transmitted to the controller and compared and analyzed with the data in the crop growth database. The artificial intelligence algorithm module uses this data to automatically adjust the spreading speed, angle and fertilizer ratio to ensure that the amount of fertilizer matches the crop growth stage and soil conditions. This intelligent fertilization strategy not only improves the accuracy of fertilization, but also helps to improve the yield and quality of crops.

[0010] The above scheme has the following beneficial effects: 1. Improve fertilization efficiency: The controller integrates and controls various components to achieve automation and intelligence of fertilization operations, greatly improving fertilization efficiency. Operators only need to set parameters through the controller to achieve precise fertilization, reducing labor costs and time costs.

[0011] 2. Strong adaptability: The fertilizer spreader of the present invention adopts a three-wheel chassis structure, has good maneuverability and stability, and is suitable for complex terrains such as farmland and orchards. At the same time, the design of the mixing component and the conveying component enables the fertilizer spreader to handle various types of fertilizers, including wet heavy organic fertilizers and lighter materials such as lime and soil conditioners.

[0012] 3. Precision fertilization: Precision fertilization is achieved through the controller's precise adjustment of parameters such as spreading speed, spreading angle, fertilizer dumping angle and flow rate. This can not only improve the utilization rate of fertilizers and reduce waste, but also avoid unnecessary damage to crops and the environment.

[0013] 4. Easy maintenance and upkeep: The design structure of the fertilizer spreader of the present invention is simple and clear, and each component is easy to disassemble and replace. This reduces maintenance costs and extends the service life of the equipment. At the same time, the fault diagnosis function integrated in the controller also makes the maintenance and upkeep of the equipment more convenient and quick.

[0014] 5. Intelligent fertilization strategy: Through the integrated artificial intelligence algorithm module, the fertilization vehicle can automatically generate and optimize fertilization strategies based on historical data and real-time monitoring information. This intelligent fertilization method not only improves the pertinence and effectiveness of fertilization, but also reduces resource waste and environmental pollution caused by excessive or insufficient fertilization.

[0015] 6. Data-driven decision-making: The convolutional neural network model integrated in the controller enables the fertilizer application vehicle to make decisions based on big data and deep learning algorithms. This data-driven decision-making method improves the scientificity and accuracy of fertilization operations and provides strong technical support for agricultural production.

[0016] 7. Improve crop yield and quality: Through precise fertilization strategies and intelligent operation methods, the fertilizer application vehicle of the present invention helps to improve crop yield and quality. This not only increases farmers' income, but also helps promote the sustainable development of agriculture.

[0017] Furthermore, the spreading structure includes a horizontal spiral spreader and a vertical double disc spreader, and both the horizontal spiral spreader and the vertical double disc spreader are connected to the controller signal.

[0018] Beneficial effects: The horizontal spiral spreader is suitable for wet and heavy organic fertilizers such as pig manure and cow manure, ensuring that the fertilizer is evenly spread and not easily blocked; while the vertical double disc spreader is suitable for lighter materials such as lime and soil conditioners, and can achieve uniform spreading over a large area. This design improves the efficiency and effect of fertilization and meets the growth needs of different crops.

[0019] Further, the conveying assembly includes a mounting frame, a second power member is fixedly connected to the mounting frame, a driven sprocket is rotatably matched with a side of the mounting frame away from the second power member, a driving sprocket is fixedly connected to the output shaft of the second power member, and a transmission chain is meshed between the driving sprocket and the driven sprocket; The conveying component has built-in ultrasonic vibrators and high-pressure airflow nozzles. The ultrasonic vibrators are installed under the transmission chain, and the high-pressure airflow nozzles are arranged at intervals along the conveying path to eliminate fertilizer adhesion and blockage. The ultrasonic vibrators and the high-pressure airflow nozzles are connected to the controller signal, and the controller adjusts the airflow pressure of the high-pressure airflow nozzle and the frequency of the ultrasonic vibrator in a linked manner, and adaptively matches them according to the real-time data of the humidity sensor.

[0020] Beneficial Effects: The design of adding a mounting frame, a second power member, a driving sprocket, a driven sprocket and a transmission chain to the conveying assembly further enhances the functionality and practicality of the fertilizer spreader. The second power member (such as an electric motor or a hydraulic motor) provides a stable power source to drive the driving sprocket to rotate. The driving sprocket and the driven sprocket are tightly engaged through the transmission chain to form a continuous conveying path, ensuring that the fertilizer is stably and continuously conveyed from the storage bin to the spreading structure. This chain conveying method has a high load-bearing capacity and wear resistance, and is suitable for conveying various types of organic fertilizers, including wet weight or granular fertilizers.

[0021] The controller can accurately control the speed of the second power member, thereby adjusting the conveying speed of the transmission chain. According to different fertilization requirements and crop growth conditions, operators can flexibly adjust the conveying speed to achieve precise fertilization. The mounting frame serves as a supporting structure, compactly combining the second power member, driving sprocket, driven sprocket and transmission chain, reducing space occupancy. This compact design makes the overall structure of the conveying assembly more concise and clear, and easy for daily maintenance and maintenance. The transmission chain is easy to inspect and replace, reducing maintenance costs and time costs.

[0022] The conveying component has built-in ultrasonic vibrators and high-pressure airflow nozzles, and the linkage adjustment of the two provides additional protection for fertilizer delivery. The ultrasonic vibrator effectively prevents adhesion and accumulation between fertilizer particles by generating high-frequency vibrations; while the high-pressure airflow nozzle further removes possible blockages by spraying high-pressure airflow. Based on the real-time data of the humidity sensor, the controller adaptively matches the airflow pressure of the high-pressure airflow nozzle with the frequency of the ultrasonic vibrator to ensure that fertilizer adhesion and blockage can be effectively eliminated under different humidity conditions, thereby improving the delivery efficiency.

[0023] Furthermore, the three-wheel chassis structure includes a base plate, a steering wheel and a plurality of driving wheels are installed at the bottom of the base plate, and a driving assembly is installed on the base plate between the steering wheel and the driving wheels, and the driving assembly is used to provide power to the driving wheels.

[0024] Beneficial effects: The three-wheel structure design makes the fertilizer vehicle have good stability and balance, and it can maintain stable driving even on uneven farmland ground. The setting of the steering wheel enables the vehicle to flexibly turn and adapt to narrow or complex farmland environments, improving maneuverability and operating efficiency. The drive assembly is installed on the bottom plate between the steering wheel and the drive wheel, ensuring the effective transmission of power from the drive assembly to the drive wheel. This design reduces energy loss during power transmission, improves driving efficiency, and enables the fertilizer vehicle to operate with higher efficiency. The reasonable layout of the steering wheel and the drive wheel enables the fertilizer vehicle to adapt to a variety of farmland terrains, including muddy, rugged or uneven ground. This design improves the operating range and applicability of the fertilizer vehicle, enabling it to carry out efficient fertilization in various complex farmland environments.

[0025] Furthermore, it also includes a heat dissipation and overload protection system, which includes a temperature sensor and a radiator. The temperature sensor and the radiator are both installed on one side of the drive component. The temperature sensor and the radiator are both connected to the controller signal. When the load from the temperature sensor to the drive component increases abnormally or is blocked, the controller controls the drive component to automatically shut down and issue an alarm, and the controller starts the radiator at the same time.

[0026] Beneficial effects: The temperature sensor can monitor the operating temperature of the drive component in real time. Once an abnormal temperature rise is found, it indicates that there may be problems such as excessive load, blockage or poor heat dissipation. When the temperature sensor detects these problems, the controller will respond quickly and control the drive component to automatically shut down, thereby effectively avoiding safety accidents such as component damage or fire caused by overheating. The overload protection system can shut down in time when the motor load increases abnormally, preventing the motor from running overloaded for a long time, thereby protecting the motor from damage. By reducing excessive wear and failure rate of the motor, the service life of the motor can be significantly extended and the maintenance and replacement costs can be reduced. The function of automatic shutdown and alarm can remind operators to pay attention to and deal with abnormal situations in time to avoid potential safety hazards. This helps to ensure that the fertilizer truck operates in a safe environment and reduce the risk of accidents caused by equipment failure.

[0027] When the temperature sensor detects an increase in temperature, the controller activates the radiator to reduce the temperature of the drive components by enhancing the heat dissipation effect. This intelligent heat dissipation management method ensures that the drive components operate within a suitable temperature range and improves their operating efficiency and stability. By stopping in time to avoid overheating and overloading, unnecessary energy consumption and emissions can be reduced, which is in line with the development trend of green and environmentally friendly modern agriculture.

[0028] Furthermore, it also includes a plurality of safety protection structures, which include safety protection covers installed on the outer side walls of the conveying component and the spreading structure.

[0029] Beneficial effects: The safety shield is installed on the outer wall of the conveying assembly and the spreading structure, effectively isolating the operator from direct contact with these key components. This prevents the operator from being injured due to accidental contact with the conveying chain, rotating parts or spreaders during operation, thereby improving the safety of the operation.

[0030] The safety cover can reduce the noise generated by the conveying components and spreading structure during operation, providing a more comfortable working environment for the operator. At the same time, it can effectively prevent fertilizer particles or fragments from splashing out during the spreading process, avoiding pollution or harm to the operator or the surrounding environment. It can also prevent foreign debris, soil or moisture from entering the equipment, causing component damage or failure, thereby extending the service life of the equipment.

[0031] Furthermore, it also includes a display and a monitoring component, the monitoring component includes a weighing sensor, the display and the weighing sensor are both connected to the controller signal, and the controller transmits the real-time monitoring data of the weighing sensor to the display.

[0032] Beneficial effects: The weighing sensor can monitor the weight of fertilizer in the storage bin in real time, ensuring that the operator knows the remaining amount of fertilizer at any time, which helps to avoid interruptions caused by insufficient fertilizer during the operation and improve the continuity and efficiency of fertilization operations. With the real-time data on the display, the operator can accurately control the amount of fertilizer applied each time to ensure that the crops can evenly absorb nutrients. This precise control helps to reduce fertilizer waste, improve fertilization effects, and reduce environmental impact.

[0033] After knowing the remaining amount of fertilizer, the operator can plan the time and route of fertilization operation more reasonably, which helps to reduce idle time and unnecessary energy consumption and improve overall operation efficiency. The intuitive data display on the monitor allows the operator to easily understand the operating status of the equipment and the amount of fertilizer.

[0040] The following is further described in detail through specific implementation methods: Embodiment 1: As attached Figures 1 to 4 As shown: an organic fertilizer fertilizing vehicle combining a broadcasting type and a dumping type fertilizing dual mode, comprising a three-wheel chassis structure, a driving assembly 4 is installed at the bottom of the three-wheel chassis structure, the three-wheel chassis structure comprises a bottom plate 1, a steering wheel 2 and two driving wheels 3 are installed at the bottom of the bottom plate 1, and the driving assembly 4 is installed on the bottom plate 1 between the steering wheel 2 and the driving wheel 3, and the driving assembly 4 is used to provide power to the driving wheel 3. A storage bin 5 for storing organic fertilizer and materials is installed on the top of the three-wheel chassis structure. In this embodiment, the driving assembly 4 is selected as a high-power diesel engine. In this embodiment, the storage bin 5 is made of corrosion-resistant material and coated with an anti-corrosion coating.

[0041] A stirring assembly is installed in the storage bin 5, and the stirring assembly includes a first power member. The output shaft of the first power member is coaxially fixedly connected with a screw rod 7, a nut seat 8 is sleeved on the screw rod 7, the nut seat 8 and the screw rod 7 form a ball screw structure, and a plurality of stirring shafts 9 are fixedly connected to the outer wall of the nut seat 8. A scraper 10 is fixedly connected to the end of the stirring shaft 9 away from the nut seat 8. In this embodiment, the first power member is a first motor 6.

[0042] A spreading structure and a dumping structure are also installed on the top of the three-wheel chassis structure. A conveying assembly is installed between the storage bin 5 and the spreading structure. The input end of the conveying assembly is connected to the storage bin 5, and the output end of the conveying assembly is connected to the spreading structure. The first power member signal is connected to a controller, and the controller is integrated with an artificial intelligence algorithm module. The artificial intelligence algorithm module has a built-in convolutional neural network model, which is used to generate a dynamic fertilization strategy through correlation analysis between historical fertilization data and crop yield; the controller signal is connected to a soil moisture sensor and a GPS positioning sensor. The controller uses an artificial intelligence algorithm module to connect the soil moisture data and position information monitored in real time by the soil moisture sensor and the GPS positioning sensor with the crop growth database signal, which is used to automatically optimize the spreading speed, angle and fertilizer ratio according to the real-time soil data and the crop growth stage.

[0043] The controller is connected to the drive component 4, the spreading structure, the dumping structure and the conveying component by signal. The controller is used to control the spreading speed and spreading angle of the spreading structure, and to control the dumping angle and flow rate of the fertilizer in the dumping structure. At the same time, the controller is used to switch the spreading structure and the dumping structure according to the characteristics of different fertilizers. The controller is also used to control the fertilizer conveying speed of the conveying component.

[0044] The spreading structure includes a horizontal spiral spreader 11 and a vertical double disc spreader 12, and both the horizontal spiral spreader 11 and the vertical double disc spreader 12 are connected to the controller signal. In this embodiment, the horizontal spiral spreader 11 model is selected: WS-1200Pro, with a width of 1.2m, which can evenly spread organic fertilizers such as pig manure and cow manure. At the same time, the vertical double disc spreader 12 can be equipped with an optional model: VD-4000i, which is suitable for spreading lime and soil conditioners, and the spreading range can be adjusted to 4m to ensure uniform distribution of fertilizers. Among them, the fertilizer spreading discs of the horizontal spiral spreader 11 and the vertical double disc spreader 12 are both selected with a diameter of 1.2 m, made of 304 stainless steel, and sprayed with an anti-corrosion coating on the surface. It also includes a display and a monitoring component, and the monitoring component includes a weighing sensor, and the display and the weighing sensor are both connected to the controller signal, and the controller transmits the real-time monitoring data of the weighing sensor to the display. In this embodiment, the weighing sensor is a digital weighing sensor with an accuracy of ±0.1kg.

[0045] The conveying assembly includes a mounting frame, on which a second power member is fixedly connected, and a driven sprocket is rotatably matched on the side of the mounting frame away from the second power member, and a driving sprocket is fixedly connected to the output shaft of the second power member, and a transmission chain is meshed on the driving sprocket and the driven sprocket. In this embodiment, the transmission chain uses a high-strength alloy steel chain with a chain width of 10mm and a load-bearing capacity of 2000kg to ensure transmission stability. In this embodiment, both the driving sprocket and the driven sprocket use a No. 45 steel sprocket with a diameter of 300mm and 15 teeth, which cooperate with the chain to form an efficient transmission system. In this embodiment, the second power member is a second motor.

[0046] The conveying component has built-in ultrasonic vibrators and high-pressure airflow nozzles. The ultrasonic vibrators are installed under the transmission chain, and the high-pressure airflow nozzles are arranged at intervals along the conveying path to eliminate fertilizer adhesion and blockage. The ultrasonic vibrators and the high-pressure airflow nozzles are connected to the controller signal, and the controller adjusts the airflow pressure of the high-pressure airflow nozzle and the frequency of the ultrasonic vibrator in a linked manner, and adaptively matches them according to the real-time data of the humidity sensor.

[0047] The specific implementation process is as follows: Before use, according to the needs of the farmland and the characteristics of the fertilizer, the operator selects appropriate organic fertilizer for fertilization. At the same time, check whether the various functions of the fertilizer spreading vehicle are intact, including the drive component 4, the stirring component, the spreading structure, the dumping structure and the conveying component. According to the operation requirements, select a suitable spreading structure (horizontal spiral spreader 11 or vertical double disc spreader 12) and adjust the corresponding spreading parameters. Load the organic fertilizer or material into the storage bin 5 to ensure that the amount of fertilizer is appropriate and avoid overloading. Observe the weight of the fertilizer in the storage bin 5 monitored in real time by the weighing sensor through the display to ensure that there is enough fertilizer for the operation.

[0048] The operator starts the high-power diesel engine of the fertilizer truck to provide power for the fertilizer truck. The operator drives the fertilizer truck to the operation area and flexibly adjusts the steering wheel 2 and the driving wheel 3 according to the farmland topography and crop distribution to ensure the stable driving of the fertilizer truck.

[0049] Then the first motor 6 is started to drive the screw 7 to rotate, thereby driving the nut seat 8 and the stirring shaft 9 to move along the screw 7. The scraper 10 on the stirring shaft 9 continuously stirs the fertilizer in the storage bin 5 to ensure that the fertilizer is evenly mixed to avoid caking or precipitation.

[0050] Through the controller, the operator can select the broadcasting or dumping fertilization mode according to the needs. The broadcasting mode is suitable for evenly distributing fertilizers, while the dumping mode is suitable for occasions where fixed-point or quantitative fertilization is required. Then, the second motor is started through the controller to drive the driving sprocket to rotate, and the power is transmitted to the driven sprocket through the transmission chain, thereby driving the conveying component to convey the fertilizer in the storage bin 5 to the broadcasting structure or the dumping structure.

[0051] When broadcast fertilization is selected, the controller controls the fertilizer conveying speed of the conveying component and the spreading speed and spreading angle of the spreading structure according to the fertilization strategy generated by the artificial intelligence algorithm module. The horizontal spiral spreader 11 or the vertical double disc spreader 12 works according to the instructions of the controller to evenly spread the fertilizer in the farmland.

[0052] When dumping fertilization is selected, the controller controls the dumping angle and flow rate of the fertilizer in the dumping structure. The dumping structure dumps the fertilizer at a fixed point or in a fixed quantity in the farmland according to the instructions of the controller.

[0053] When the fertilizer begins to be transported, the controller will adaptively adjust the airflow pressure of the high-pressure airflow nozzle and the frequency of the ultrasonic vibrator according to the soil moisture data monitored in real time by the soil moisture sensor. If the soil moisture is high, the fertilizer is more likely to stick. At this time, the controller will increase the airflow pressure of the high-pressure airflow nozzle and increase the frequency of the ultrasonic vibrator to more effectively eliminate the adhesion and blockage of the fertilizer. Conversely, when the soil moisture is low, the controller will reduce the airflow pressure and ultrasonic frequency accordingly to avoid unnecessary energy consumption and equipment wear. This adaptive matching mechanism ensures the smoothness of the fertilizer during transportation and avoids fertilization interruptions caused by blockages. At the same time, it also improves the efficiency and uniformity of fertilizer transportation, thereby further improving the quality and effect of fertilization operations.

[0054] During the operation, the operator can observe the operation status of the equipment and the remaining amount of fertilizer in real time through the display. According to the actual situation of the farmland and the needs of the crops, the operator can adjust the parameters such as sowing speed, sowing angle, dumping angle and flow rate through the controller to ensure the best fertilization effect.

[0055] When the fertilization operation is completed, the operator turns off the engine and disconnects the power supply to ensure that the equipment is in a safe state. Regular inspection and maintenance of the fertilization vehicle, including cleaning the equipment, replacing worn parts, and checking the wear of the transmission chain and sprocket, etc., to ensure the long-term stable operation of the equipment.

[0056] Through the above specific implementation process, this organic fertilizer fertilization vehicle that combines broadcasting and dumping fertilization modes can flexibly adapt to different farmland environments and crop needs, and achieve efficient and accurate fertilization operations. At the same time, the intelligent control and real-time monitoring functions of the equipment also greatly improve the operating efficiency and safety of operators.

[0057] Embodiment 2: The difference from Example 1 is that it also includes a heat dissipation and overload protection system, which includes a temperature sensor and a radiator. The temperature sensor and the radiator are both installed on one side of the drive component 4. The temperature sensor and the radiator are both connected to the controller signal. When the load from the temperature sensor to the drive component 4 increases abnormally or is blocked, the controller controls the drive component 4 to automatically shut down and issue an alarm, and the controller starts the radiator at the same time. In this embodiment, the radiator uses an aluminum alloy radiator with a surface area of ​​0.5m², a built-in dual fan, and a rotation speed of 2500rpm to ensure that the device maintains a suitable temperature during operation.

[0058] The specific implementation process is as follows: During the operation of the fertilizer application vehicle, the temperature sensor continuously monitors the temperature of the drive component 4. Once the temperature sensor detects that the load of the drive component 4 is abnormally increased or blocked, resulting in a temperature rise, the controller immediately responds, controls the drive component 4 to automatically shut down, and issues an alarm through the alarm system to alert the operator. At the same time, the controller starts the radiator, and the dual fans built into the aluminum alloy radiator run at a high speed of 2500rpm, quickly taking away the heat generated by the drive component 4, ensuring that the equipment temperature remains within an appropriate range to prevent overheating damage.

[0059] When the operator hears the alarm, he should stop the vehicle immediately to check the drive assembly 4 and related parts to find out the cause of the fault. If problems such as blockage or excessive load are found, clean or adjust them in time to ensure that the fertilizer spreader can return to normal working state. After the fault is eliminated, restart the fertilizer spreader and continue the fertilization operation.

[0060] By real-time monitoring of the temperature of the drive assembly 4, and automatically shutting down and sounding an alarm in abnormal situations, equipment damage or safety accidents caused by overheating are effectively avoided. The efficient heat dissipation function of the radiator ensures that the drive assembly 4 maintains a suitable temperature during operation, reduces wear and aging caused by high temperature, and extends the service life of the equipment. Under the protection of the heat dissipation and overload protection system, the fertilizer spreading vehicle can work continuously and stably, avoiding operation interruptions caused by fault shutdowns, and improving the efficiency and continuity of fertilization operations.

[0061] Embodiment 3: The difference from Example 2 is that it also includes a plurality of safety protection structures, which include safety protection covers installed on the outer side walls of the conveying assembly and the spreading structure.

[0062] The specific implementation process is as follows: the safety shield is installed on the outer wall of the conveying assembly and the spreading structure to prevent the operator or other personnel from accidentally contacting the moving parts during the fertilization operation, thereby avoiding potential safety hazards.

[0063] The safety cover is made of strong and durable materials to resist the impact and abrasion of fertilizer particles, while maintaining good transparency or permeability so that the operator can clearly observe the operation of the internal components.

[0064] The safety cover can effectively prevent operators or other personnel from accidentally contacting the running parts during the fertilization operation, thus greatly reducing the risk of safety accidents. At the same time, the safety cover can resist the impact and wear of fertilizer particles, extending the service life of key parts of the fertilization vehicle.

[0065] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
