[0026] The embodiments that have been found in the art to be feasible and can be added to the present invention are:

[0027] Robotic Arm

[0028] The robot arm is a complex system with high precision, multiple inputs and multiple outputs, high nonlinearity, and strong coupling. It is widely used in industrial assembly, safety and explosion-proof and other fields. It consists of a series of rigid components connected by links (joints), with arms to ensure mobility, wrists to provide flexibility, and end effectors to perform tasks required by the robot. The degree of freedom of the robot arm determines its flexibility of movement. Common industrial robot arms include four-axis, five-axis, six-axis, etc.

[0029] The main driving modes of the robot arm are hydraulic, pneumatic and electric. Hydraulically driven robot arms usually have large grabbing capacity and good movement stability, but the hydraulic components require high manufacturing precision and sealing performance. Pneumatically driven robot arms have fast movements, simple structures, and low costs, but low grabbing capacity. Electric drive is the most widely used method at present, with the characteristics of convenient power supply, fast response, large driving force, and convenient signal detection, transmission, and processing.

[0030] conveyor

[0031] Conveyor belt is a composite material used in belt conveyors to carry and transport materials. It is widely used in various industrial fields. Conveyor belt can realize continuous, high-efficiency, large-angle transportation, safe operation, easy use, easy maintenance, low freight, and can shorten the transportation distance, reduce project costs, and save manpower and material resources.

[0032] Classification of conveyor belts: Conveyor belts can be divided into many types according to different standards. According to the material, they can be divided into rubber conveyor belts, plastic conveyor belts, metal conveyor belts, etc.; according to the use environment and the special performance required, they can be divided into tropical belts, wear-resistant belts, oil-proof belts, acid- and alkali-proof belts, etc.

[0033] Key parameters of conveyor belts: Performance parameters of conveyor belts include belt width, belt length, belt thickness, tensile strength, abrasion, interlayer bonding strength, etc. These parameters determine the conveyor belt's carrying capacity, wear resistance, tension resistance and applicable working conditions.

[0034] Application of conveyor belts: conveyor belts play an important role in modern logistics and production, not only improving work efficiency but also reducing the burden of manual labor. In the logistics industry, conveyor belts are used in cargo handling, warehousing and sorting systems; in the manufacturing industry, conveyor belts are used for the transportation of raw materials and semi-finished products; in mines and quarries, conveyor belts are used for long-distance transportation of large quantities of materials.

[0035] Conveyor belt maintenance: Proper maintenance and care can extend the service life of the conveyor belt, including regular inspection, cleaning, lubrication and other measures. When the conveyor belt is worn or broken, it should be replaced in time to ensure the continuity and safety of production.

[0036] At present, conveyor belt technology is developing towards automation and intelligence. Intelligent conveyor belts with integrated sensors and control systems can automatically detect and adjust the operating status, improving the flexibility and adaptability of the production line. In addition, new conveyor belt materials and designs are constantly being introduced to meet more demanding industrial application requirements.

[0037] Humidity Sensor

[0038] A humidity sensor is a device used to measure the humidity of an environment. It can convert humidity information into electrical signals for easy reading and processing. The working principle of humidity sensors is mainly based on the properties of humidity-sensitive elements, which are usually resistive or capacitive. Resistive humidity sensors use the property that the resistance of a material changes with humidity, while capacitive humidity sensors rely on the change in capacitance caused by humidity changes to measure humidity.

[0039] Humidity sensors are widely used in many fields such as meteorological monitoring, agriculture, industrial control, warehouse management, building environment, medical equipment, electronic manufacturing, etc. In these applications, humidity sensors can help control environmental conditions, ensure product quality, prevent mildew and corrosion, and optimize production processes.

[0040] In recent years, humidity sensors have achieved significant technological innovations in terms of sensitivity, response time, stability, and cost. The application of nanotechnology, breakthroughs in thin film technology, the development of integration and intelligence, and the advancement of self-powered and energy harvesting technologies have all driven humidity sensors to develop in the direction of higher performance and wider applications.

[0041] Embodiments that can also be added to the present invention are:

[0042] Control Module

[0043] Control modules are key components used to manage and control equipment operations. They usually integrate microprocessors and various electronic components to perform specific tasks such as starting, stopping, and adjusting equipment according to predetermined programs or external inputs. Control modules are also responsible for real-time monitoring of equipment performance parameters and operating status to ensure that the equipment operates in the best condition, and process and analyze data to optimize equipment operating efficiency and performance.

[0044] The design and functions of control modules may vary in different application areas. For example, a control module in an industrial automation system may need to process signals from various sensors and drive actuators or other devices; while in an autonomous driving system, the control module may be responsible for vehicle steering, throttle, and brake control tasks.

[0045] The working principle of the control module usually includes input signal recognition and processing, control algorithm operation, output signal generation and driving, feedback signal acquisition and closed-loop control. In this way, the control module can achieve precise control of the system and improve the stability and response speed of the system.

[0046] In the development of modern industry and technology, the intelligence and networking of control modules are becoming more and more important. They can not only control equipment locally, but also realize remote monitoring and control through industrial Internet of Things technology, support multi-device management and collaborative work, which is of great significance for improving production efficiency, reducing maintenance costs and realizing remote operation and maintenance.

[0047] The motor rotates at a fixed angle intermittently

[0048] Intermittent fixed-angle rotation of a motor usually involves precisely controlling the angle of rotation of the motor to achieve a desired motion in an automation or precision positioning system.

[0049] The following are several control methods to achieve intermittent fixed-angle rotation of the motor:

[0050] Stepper motor control: Stepper motors can be controlled by sending pulse signals to control the rotation angle, each pulse represents a fixed angle increment. By precisely controlling the number and sequence of pulses, intermittent fixed angle rotation of the motor can be achieved.

[0051] Servo motor control: Servo motors can operate in position control mode, where a specific number of pulses are input to set the angle of the motor's rotation. Combined with feedback devices such as encoders, closed-loop control can be achieved to improve the accuracy and repeatability of the rotation angle.

[0052] PWM control: For some types of motors, such as brushless DC motors, pulse width modulation (PWM) can be used to adjust the average voltage of the motor, thereby controlling the speed and rotation angle of the motor. By accurately controlling the PWM signal, intermittent fixed-angle rotation of the motor can be achieved.

[0053] Closed-loop feedback control: Using a position feedback sensor (such as an encoder) can provide the current angle information of the motor, and adjust the motor drive signal through a closed-loop control algorithm (such as PID control) to achieve precise angle control.

[0054] Vector control and model predictive control: These are more advanced control strategies suitable for applications that require high performance and high-precision control. They achieve more precise angle control by optimizing the control parameters of the motor.

[0055] Hot air drying and infrared heating

[0056] Hot air drying and infrared heating are two commonly used heating and drying technologies.

[0057] Hot air drying: Hot air drying is to directly contact the object through the hot air medium, and use the hot air convection circulation method to exchange moisture and heat with the object to evaporate the moisture inside the object. Hot air drying usually has a large gas-solid two-phase heat and mass transfer surface area, and can use high-temperature heat medium for drying. The higher the moisture content of the material, the higher the temperature of the drying medium can be. The characteristics of the hot air drying system are high thermal efficiency, long drying time, large processing capacity, simple structure, large production capacity, and easy operation.

[0058] Infrared heating: Infrared heating uses the principle of infrared rays, which are directly transmitted to the heated object in the form of electromagnetic waves. After the molecules inside the object absorb the infrared rays, they vibrate and rotate, thereby increasing the temperature of the object and achieving the purpose of heating. Infrared heating has the characteristics of non-contact heating, no need for intermediate media, high penetration, etc., and can achieve directional or local heating.

[0059] Hot air drying heats the object by direct contact with the hot air medium, while infrared heating directly radiates electromagnetic waves to the surface of the object. Due to its high penetration and direct heating characteristics, infrared heating usually heats faster.

[0060] Micro atomizing nozzle

[0061] Micro-atomizing nozzles are nozzles that can produce very fine water droplets. They are widely used in industry, agriculture, medical treatment and daily life. The characteristics of micro-atomizing nozzles include very fine and uniform atomized particles, which can save energy while covering a large area, and the atomized water can evaporate quickly.

[0062] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0063] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0064] Reference Figure 1-Figure 5 The present invention provides a wide-mouth bottle soil moisture measurement and control system, including a detection platform 10, a top surface of the detection platform 10 is provided with a driving mechanism control module for controlling the intermittent movement of the wide-mouth bottle 6, a side of the detection platform 10 is provided with a detection station 5 for detecting the moisture of the soil in the wide-mouth bottle 6, and a side of the detection platform 10 away from the detection station 5 is provided with a loading and unloading control module 20 for loading the wide-mouth bottle 6 to the driving mechanism control module or unloading the wide-mouth bottle 6 on the driving mechanism control module.

[0065] The loading and unloading control module 20 includes a robotic arm and a conveyor belt. The conveyor belt carries the wide-mouth bottle 6 to a position near the loading and unloading port 4. The robotic arm carries the wide-mouth bottle 6 to be sleeved into the hanging slot 2, so that the wide-mouth bottle 6 is sleeved and suspended in the hanging slot 2; at this time, the bottom surface of the wide-mouth bottle 6 is separated from the conveyor belt, and the hanging slot 2 is controlled to rotate with the wide-mouth bottle 6 to be transmitted to the side close to the detection station 5 by the loading plate 1. After the detection station 5 completes the inspection of the wide-mouth bottle 6, the wide-mouth bottle 6 rotates one circle with the center of the loading plate 1 as the center and returns to the position of the loading and unloading port 4, and the robotic arm is controlled again to grab the wide-mouth bottle 6, and the inspected wide-mouth bottle 6 is placed on the conveyor belt, and the wide-mouth bottle 6 is unloaded through the conveyor belt.

[0066] The present invention realizes batch transmission of wide-mouth bottles 6 through the loading and unloading control module 20, and controls the intermittent movement of the wide-mouth bottles 6 through the driving mechanism control module, so that the detection station 5 can monitor the soil in the wide-mouth bottles 6 in real time, and can quickly, efficiently and accurately detect soil moisture.

[0067] The present invention not only improves detection efficiency and reduces manual intervention, but also effectively ensures the accuracy and reliability of batch detection and meets the needs of soil moisture detection.

[0068] Further optimization scheme, the driving mechanism control module includes a limit stop ring 3 fixedly connected to the top surface of the detection platform 10, and a loading and unloading port 4 is opened on the side of the limit stop ring 3 facing the loading and unloading control module 20, and a loading plate 1 for driving the wide-mouth bottle 6 to move in the limit stop ring 3 is rotatably connected in the limit stop ring 3. The loading plate 1 rotates in the limit stop ring 3, so that the loading plate 1 can move the wide-mouth bottle 6 in the limit stop ring 3.

[0069] In a further optimized solution, a plurality of suspension grooves 2 are evenly spaced on one side of the loading tray 1 facing the inner wall of the limiting retaining ring 3, and the suspension grooves 2 are adapted to the wide-mouth bottle 6. The suspension grooves 2 are distributed in a circular array along the center of the loading tray 1; in order to enable the wide-mouth bottle 6 to move stably in the limiting retaining ring 3, the wide-mouth bottle 6 is placed in the suspension grooves 2, so that the wide-mouth bottle 6 can move stably in the limiting retaining ring 3 under the drive of the suspension grooves 2.

[0070] A limiting space is formed between the inner wall surface of the suspension groove 2 and the inner wall surface of the limiting baffle ring 3, so as to limit the wide-mouth bottle 6.

[0071] When in use, the wide-mouth bottle 6 is placed in the hanging groove 2. At this time, the loading plate 1 rotates with the wide-mouth bottle 6 to change the distribution position. When the loading plate 1 and the wide-mouth bottle 6 are transferred to the corresponding detection station 5, the humidity of the soil in the wide-mouth bottle 6 is detected through the detection station 5. By controlling the intermittent rotation of the loading plate 1, the loading plate 1 and the multiple wide-mouth bottles 6 are rotated and distributed to the corresponding detection station 5 in turn, thereby facilitating the continuous detection operation of the multiple wide-mouth bottles 6. After the detection, the wide-mouth bottle 6 rotates one circle and then returns to the loading and unloading port 4. At this time, it is convenient to unload the wide-mouth bottle 6.

[0072] Further optimization scheme, the center of one end of the loading tray 1 facing the detection platform 10 is connected to a motor through a transmission shaft, and the motor is fixedly connected to the detection platform 10. The motor drives the transmission shaft to rotate intermittently according to the set rotation angle, and the transmission shaft drives the loading tray 1 to rotate, and the wide-mouth bottle 6 moves accordingly. When a wide-mouth bottle 6 reaches the detection station 5, the loading tray 1 stops rotating, and the humidity sensor on the detection station 5 starts working to collect the humidity data of the soil in the wide-mouth bottle 6, and analyze the current humidity state of the soil through the data processing module. After the humidity detection is completed, the detection data is stored in the database for subsequent analysis and query. The wide-mouth bottle 6 that has been detected continues to rotate with the loading tray 1 until the next wide-mouth bottle 6 enters the detection station, and the above detection steps are repeated until all the soil samples in the wide-mouth bottle 6 are detected. After the soil samples in the wide-mouth bottle 6 are detected, the loading tray 1 moves them to the position of the loading and unloading port 4, and the wide-mouth bottle 6 can be unloaded.

[0073] According to a further optimization scheme, the detection station 5 includes a connecting seat 11 fixedly connected to the detection platform 10, and a detection station control module for detecting soil is arranged on the top surface of the connecting seat 11, and a cleaning component for cleaning the detection station control module is arranged on one end of the connecting seat 11 facing the limit stop ring 3.

[0074] The soil humidity in the wide-mouth bottle 6 located at the detection station 5 is detected by a humidity sensor. The humidity sensor can accurately reflect the moisture content in the soil by measuring the change in the dielectric constant of the soil. When the wide-mouth bottle 6 enters the detection station 5, the humidity sensor contacts the soil surface in the wide-mouth bottle 6 and starts to collect soil humidity data. After the detection is completed, in order to avoid the residual humidity or soil particles from the previous detection affecting the next detection, the humidity sensor can effectively detect the humidity of the soil in the next wide-mouth bottle 6. The sensor must be effectively cleaned, and the humidity sensor can be cleaned by cleaning the component.

[0075] Further optimizing the scheme, the detection station control module includes a lifting platform 13 arranged above the connecting seat 11, the lifting platform 13 and the connecting seat 11 are fixedly connected by a plurality of telescopic rods 12, the lifting platform 13 is slidably connected to a moving seat 14 on one side facing the limit ring 3, and a humidity sensor for detecting soil humidity is fixedly connected to the bottom of the moving seat 14. The humidity sensor adopts a capacitive soil humidity sensor, which can accurately reflect the moisture content in the soil by measuring the change of the soil dielectric constant.

[0076] In order to effectively control the movement of the movable seat 14, the movable seat 14 is threadedly connected with a lead screw, and the lead screw is rotatably connected with a slide groove. The slide groove is opened on the lifting platform 13, and the lead screw is driven to rotate by a driving motor. The lead screw drives the movable seat 14 to move along the slide groove. Through the movable seat 14, the humidity sensor can be controlled to move back and forth along the direction of the lead screw.

[0077] The telescopic rod 12 is a hydraulic cylinder or an electric telescopic rod. The telescopic rod 12 drives the lifting platform 13 to move up and down, so that the height of the humidity sensor can be controlled.

[0078] In a further optimized solution, the cleaning assembly includes a sewage collection box 17 fixedly connected to the end of the connection seat 11 facing the detection platform 10, and a self-cleaning module 18 for cleaning the humidity sensor is arranged in the sewage collection box 17, and the self-cleaning module 18 is connected to the water tank 16. In order to allow a space for placing the water tank 16, a placement groove 15 is provided on the outer wall of the connection seat 11. By placing the water tank 16 in the placement groove 15, the water tank 16 can be protected and prevented from being damaged by external influences.

[0079] The self-cleaning module 18 can clean the humidity sensor by spraying water in the water tank 16 toward the humidity sensor, thereby effectively improving the accuracy of the humidity sensor in detecting the soil humidity in the next wide-mouth bottle 6 .

[0080] According to a further optimization scheme, the self-cleaning module 18 includes an air outlet pipe for spraying air to the humidity sensor, and a nozzle for spraying the humidity sensor, and the nozzle is connected to the water tank 16 .

[0081] The humidity sensor is cleaned by the nozzle, which effectively improves the accuracy of the humidity sensor in detecting the soil humidity in the next wide-mouth bottle 6. The nozzle adopts an atomizing nozzle, which can perform a micro-spray cleaning on the humidity sensor. The water tank 16 is filled with a cleaning agent, and the cleaning agent adopts distilled water or a neutral solvent.

[0082] To further optimize the solution, the air outlet pipe is connected to an air pump. The air pump sprays air to the humidity sensor through the air outlet pipe, which can effectively remove soil particles or moisture attached to the humidity sensor and ensure the surface of the humidity sensor is clean.

[0083] In a further optimized solution, a drying module 19 for drying the humidity sensor is provided above the sewage collection box 17, and the drying module 19 is fixedly connected to the outer wall of the connection seat 11 on the side facing the detection platform 10. After the humidity sensor is cleaned, the drying module 19 can dry the surface of the humidity sensor by hot air drying and infrared heating, which can effectively ensure that there is no water residue in the detection area of ​​the humidity sensor, so that the humidity sensor can be restored to a state suitable for the next round of detection in a short time.

[0084] Working process:

[0085] The empty hanging tank 2 is placed at the loading and unloading port 4. After the conveyor belt conveys several wide-mouth bottles 6 containing soil to be tested to the position of the robot arm, the robot arm sets the wide-mouth bottle 6 through the loading and unloading port 4 and hangs it in the hanging tank 2. Then the loading plate 1 rotates to place the next empty hanging tank 2 at the loading and unloading port 4. The wide-mouth bottle 6 on the conveyor belt of the robot arm is placed in the hanging tank 2. The placement of the wide-mouth bottle 6 is repeated by the robot arm. When a wide-mouth bottle 6 is at the testing station 5, the moving seat 14 drives the humidity sensor to move to the upper side of the wide-mouth bottle 6. The telescopic rod 12 drives the lifting platform 13 to descend, so that the humidity sensor contacts the soil surface in the wide-mouth bottle 6, and starts to collect soil moisture data in the wide-mouth bottle 6. After the collection and detection is completed, the lifting platform 13 rises, so that the humidity sensor is above the wide-mouth bottle 6, and then the moving seat 14 drives the humidity sensor to be above the sewage collection box 17. At this time, the lifting platform 13 descends, so that the humidity sensor is in the sewage collection box 17, and then, the air pump is used to spray air to the humidity sensor through the air outlet pipe, which can effectively remove the soil particles or moisture attached to the humidity sensor. When there is a sticky substance attached to the humidity sensor, the cleaning liquid in the water tank 16 is sprayed from the nozzle through the water pump to spray and clean the humidity sensor. After spray cleaning, the humidity sensor is placed in the position of the drying module 19 through the lifting platform 13, and the humidity sensor is dried by blowing hot air or infrared heating through the drying module 19. The surface of the humidity sensor is kept dry by hot air drying and infrared heating, ensuring that there is no water residue in the detection area of ​​the humidity sensor. Dry to ensure that the humidity sensor recovers to a state suitable for the next round of detection in a short time; at this time, through the rotation of the loading plate 1, the next wide-mouth bottle 6 to be tested is at the detection station 5, so that the humidity sensor can detect the soil in the wide-mouth bottle 6; when the tested wide-mouth bottle 6 is at the loading and unloading port 4, at this time, the robot arm first places the wide-mouth bottle 6 on the conveyor belt, and then places the wide-mouth bottle 6 to be tested on the conveyor belt into the empty hanging slot 2, and the wide-mouth bottle 6 can be automatically unloaded through the robot arm, the conveyor belt and the hanging slot 2.

[0086] The present invention adopts a capacitive soil moisture sensor, which can sensitively detect the change of the soil dielectric constant, and accurately reflects the moisture state of the soil in the wide-mouth bottle 6. The soil moisture in each wide-mouth bottle 6 is monitored in real time by the detection station 5, so that accurate and rapid humidity detection can be achieved, thereby improving the overall detection efficiency and accuracy; in addition, the precise control of the loading plate 1 by the drive mechanism control module can ensure that the wide-mouth bottle 6 moves accurately at the detection station 5, so that each wide-mouth bottle 6 is automatically and accurately positioned at the detection station 5, thereby ensuring the detection accuracy.

[0087] The present invention can realize fully automated loading and unloading of wide-mouth bottles 6 through the loading and unloading control module 20; the intermittent rotation and stopping of the loading plate 1 enable the wide-mouth bottles 6 to reach the detection station 5 in turn and return to the loading and unloading port 4, and automatically unload after detection. The automated design not only reduces the operating difficulty, but also reduces the need for manual intervention, thereby ensuring the efficiency and consistency of the detection process, helping to improve the operational efficiency of batch detection, and is suitable for large-scale soil sample moisture detection scenarios.

[0088] The self-cleaning module 18 and the drying module 19 in the present invention can automatically clean the humidity sensor after each detection to ensure that there are no residual soil particles or moisture on the surface of the humidity sensor. The self-cleaning module 18 uses air injection and micro-spraying to remove sticky soil and moisture residues on the surface of the humidity sensor to avoid interference of the residues from the previous detection on the next detection, thereby improving the independence and accuracy of each detection data.

[0089] At the same time, in order to effectively improve the detection efficiency, a drying module 19 is set up. After each cleaning, the humidity sensor can quickly and completely dry the surface of the sensor probe through hot air drying and infrared heating, so that it can be restored to its initial state in the shortest time, so that the humidity sensor can be on standby in the best condition after each detection, ensuring the continuity of the detection operation and improving the fluency and response speed of the detection process.
