Description

Technical Field

[0001] The present invention relates to the technical field of agricultural seed screening, and in particular to an agricultural planting seed screening system based on weight detection. Background Art

[0002] In the agricultural planting process, the quality of seeds directly affects the growth, yield and quality of crops. High-quality seeds have higher germination rate, vitality and stress resistance, and can better adapt to the planting environment and thrive;

[0003] During the harvest, storage and transportation of seeds, individual quality differences may occur due to various factors, such as incomplete development, pests and diseases, mechanical damage, etc. These low-quality seeds mixed in will reduce the overall sowing quality and affect agricultural production efficiency. Traditional seed screening methods mainly include manual screening and mechanical screening based on size and shape screening;

[0004] Manual screening is inefficient, labor-intensive, and unstable in accuracy; mechanical screening based on size and shape screening is difficult to distinguish differences in internal seed quality and cannot effectively remove seeds that appear normal but are underdeveloped or damaged internally, resulting in lighter weight;

[0005] Therefore, the present invention proposes an agricultural planting seed screening system based on weight detection. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and to provide an agricultural seed screening system based on weight detection.

[0007] In order to achieve the above-mentioned object, the present invention adopts the following technical scheme: an agricultural planting seed screening system based on weight detection, comprising a feeding device module, a weight detection device module, a grading device module, a control module, a calibration unit and a fault warning unit;

[0008] The control module includes a microprocessor, a data acquisition module, a control module, and a human-computer interaction interface;

[0009] The weight detection device module includes a high-precision electronic scale.

[0010] As a preferred embodiment, the feeding device module includes a hopper, a vibrating feeder and a conveying pipeline.

[0011] The beneficial effect of adopting the above further scheme is that the hopper is used to store seeds, the vibrating feeder keeps the seeds in a loose state in the hopper through vibration and enters the conveying pipe in an orderly manner, and the conveying pipe smoothly delivers the seeds to the inlet of the weight detection device.

[0012] As a preferred implementation, the grading device module includes a grading channel and a baffle.

[0013] The beneficial effect of adopting the above further scheme is that the grading device grades and screens the seeds according to the detection results of the weight detection device. It includes multiple grading channels and corresponding baffles. The number of grading channels can be set according to the actual seed screening accuracy requirements and the seed weight distribution range. It is generally set to 3-5 channels, corresponding to seeds in different weight ranges. The baffle is controlled by the control system to open and close. When the seed weight data is transmitted to the control system, the control system determines the grading channel that the seed should enter according to the preset weight threshold, and controls the baffle of the corresponding channel to open, so that the seed falls into the corresponding channel.

[0014] As a preferred implementation, the calibration unit includes a standard weight and a calibration program, and the calibration unit is electrically connected to a high-precision.

[0015] The beneficial effect of adopting the above further scheme is that before the system is operated or during regular operation, standard weights can be placed on the scale pan of the weight detection device, and the electronic scale can be calibrated through a calibration program to adjust the measurement accuracy of the electronic scale.

[0016] As a preferred implementation, the fault warning unit includes fault detection and alarm functions.

[0017] The beneficial effect of adopting the above further scheme is: once a fault is detected, a fault signal is immediately sent to the control system. The control system displays the fault information and sounds an alarm through the human-computer interaction interface to remind the operator to perform repairs in time. At the same time, the system also records information such as the time, location and type of the fault, which is convenient for subsequent fault troubleshooting and maintenance.

[0018] As a preferred implementation, the weight detection device module is electrically connected to the fault warning unit.

[0019] The beneficial effect of adopting the above further solution is that by connecting the weight detection device module with the fault warning unit, the operating status of each component can be monitored in real time through the fault detection module during use.

[0020] As a preferred implementation manner, the data acquisition module is electrically connected to the microprocessor, and the microprocessor is electrically connected to the control module.

[0021] The beneficial effect of adopting the above further scheme is: the data acquisition module transmits data to the microprocessor, the microprocessor processes and analyzes the data, and compares it with the preset weight threshold. If three grading channels are set, they correspond to high-quality seeds with a weight greater than threshold A, medium-quality seeds with a weight between threshold A and threshold B, and low-quality seeds with a weight less than threshold B.

[0022] As a preferred implementation manner, the control module is electrically connected to the baffle, and the grading device module is electrically connected to the fault warning unit.

[0023] The beneficial effect of adopting the above further scheme is: when the microprocessor determines that the seed weight is greater than the threshold value A, an instruction is sent to the control module to control the baffle of the corresponding high-quality seed grading channel to open, and the seeds fall into the channel; if the seed weight is between the threshold value A and the threshold value B, the baffle of the medium-quality seed grading channel is controlled to open; if the seed weight is less than the threshold value B, the baffle of the low-quality seed grading channel is controlled to open.

[0024] As a preferred embodiment, the device for repairing bare soil vegetation on the foundation of a power line tower in a high altitude area as described in claims 1 to 7 further comprises:

[0025] S1. System installation: Install the feeding device, weight detection device, grading device and control system according to the design requirements, ensure that all components are firmly and stably connected, and connect the electrical circuits between the components, including the data transmission line between the weight detection device and the control system, and the control line between the control system and the grading device.

[0026] S2. System debugging: First, turn on the vibrating feeder of the feeding device, check the conveying condition of the seeds in the conveying pipe, adjust the vibration frequency and the slope of the conveying pipe so that the seeds can enter the weight detection device evenly and smoothly, then calibrate the weight detection device, place the standard weights on the scale pan, perform calibration operations according to the calibration procedure, ensure that the measurement accuracy of the electronic scale meets the requirements, finally, test the grading device, manually control the opening and closing actions of the baffles of each grading channel through the control system, and check its flexibility and accuracy.

[0027] S3. Pour the seeds to be screened into the hopper of the feeding device, start the system, and the vibrating feeder starts working. The seeds enter the weight detection device through the conveying pipeline. The weight detection device detects the seeds one by one or in batches, and transmits the weight data to the control system. The control system controls the baffle action of the grading device according to the preset weight grading standard, and screens the seeds into different grading channels respectively. The screened seeds are collected in the collection containers of each grading channel. The operator can perform subsequent processing on seeds of different grades as needed, such as high-quality seeds for sowing, medium-quality seeds for further processing or for other purposes, and poor-quality seeds for elimination.

[0028] S4. Regularly perform maintenance on the system, clean the residual seeds and impurities in the feeding device, weight detection device and grading device to prevent them from affecting the operation of the system, check whether the connection parts of each component are loose, whether the electrical circuit is damaged, if there is any problem, tighten and repair it in time, calibrate the weight detection device regularly to ensure the stability of its measurement accuracy, at the same time, check the fault records of the system, focus on the inspection and maintenance of the faulty parts that have occurred before, and prevent the fault from happening again.

[0029] Compared with the prior art, the advantages and positive effects of the present invention are:

[0030] 1. In the present invention, the weight difference between seeds can be accurately detected, and the well-developed and full high-quality seeds can be effectively distinguished from the inferior seeds that are light in weight due to poor development, damage or pests and diseases. Compared with the traditional manual screening or mechanical screening methods based only on size and shape, the screening accuracy is greatly improved, and a better quality seed guarantee is provided for agricultural production. The system can realize automatic continuous operation, and can quickly perform weight detection and graded screening on a large number of seeds, and process a large number of seeds in a short time, which greatly improves the work efficiency of seed screening. It is especially suitable for seed pretreatment for large-scale agricultural planting, which helps to shorten the preparation time before sowing.

[0031] 2. In the present invention, the traditional manual seed screening method requires a lot of manpower and time, and the accuracy and stability of manual screening are difficult to guarantee. The system can replace manual labor to complete the tedious screening work, reduce the dependence on manual labor, reduce labor costs, and also avoid screening errors caused by human factors. By accurately removing inferior seeds that do not meet the weight standards and leaving high-quality seeds for sowing, the overall quality of sowing seeds can be significantly improved, and the seeds can perform better in terms of germination rate, growth potential, stress resistance, etc., thereby improving the yield and quality of crops and increasing agricultural production efficiency.

[0032] 3. In the present invention, the control system can record and store relevant data such as seed weight, provide data support for agricultural production, facilitate growers to trace and analyze seed quality, and help optimize planting management decisions. For example, according to the quality of different batches of seeds, the sowing amount and fertilization plan are adjusted to achieve precision agricultural management. The various components in the system have been carefully designed and selected, with high stability and reliability, and can maintain a good working condition during long-term continuous operation. At the same time, the fault detection and alarm function can promptly detect and remind staff to deal with system faults, further ensuring the normal operation of the system and reducing production delays caused by equipment failures.

[0033] Figure 1This is a front view of an agricultural seed screening system based on weight detection according to the present invention;

[0034] Figure 2 The present invention is a flow chart of an agricultural planting seed screening system based on weight detection. DETAILED DESCRIPTION

[0035] 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.

[0036] like Figure 1-2 As shown, the present invention provides a technical solution: an agricultural seed screening system based on weight detection, comprising a feeding device module, a weight detection device module, a grading device module, a control module, a calibration unit and a fault warning unit;

[0037] The control module includes a microprocessor, a data acquisition module, a control module, and a human-computer interaction interface. The control system is composed of a microprocessor, a data acquisition module, a control module, and a human-computer interaction interface. The data acquisition module is connected to the electronic scale of the weight detection device, responsible for collecting seed weight data and transmitting it to the microprocessor. The microprocessor processes and analyzes the collected data, determines the grade of the seeds according to the preset weight grading standard, and sends instructions to the control module. The control module controls the opening and closing of the baffle in the grading device. The human-computer interaction interface is used to set seed weight grading parameters, display system operation status and screening results and other information, so that operators can monitor and adjust the system conveniently;

[0038] The weight detection device module includes a high-precision electronic scale. The weight detection device is the core component of the system. It uses a high-precision electronic scale. The scale pan is designed as a special grid structure, which can not only carry seeds, but also allow airflow to pass smoothly, avoiding the airflow affecting the accuracy of seed weight measurement. When the seeds fall on the scale pan, the electronic scale can quickly and accurately measure the weight of the seeds and transmit the weight data to the control system.

[0039] The feeding device module includes a hopper, a vibrating feeder and a conveying pipeline. The hopper is used to store seeds. The vibrating feeder keeps the seeds in a loose state in the hopper through vibration and enters the conveying pipeline in an orderly manner. The conveying pipeline smoothly delivers the seeds to the entrance of the weight detection device.

[0040] The grading device module includes a grading channel and a baffle. The grading device grades and screens the seeds according to the detection results of the weight detection device. It includes multiple grading channels and corresponding baffles. The number of grading channels can be set according to the actual seed screening accuracy requirements and the seed weight distribution range. It is generally set to 3-5 channels, corresponding to seeds in different weight ranges. The baffle is controlled by the control system to open and close. When the seed weight data is transmitted to the control system, the control system determines the grading channel that the seed should enter according to the preset weight threshold, and controls the baffle of the corresponding channel to open, so that the seed falls into the corresponding channel.

[0041] The calibration unit includes standard weights and a calibration program. The calibration unit is connected to the high-precision electronic device. Before the system is operated or during regular operation, the standard weights can be placed on the scale pan of the weight detection device. The electronic scale can be calibrated through the calibration program to adjust the measurement accuracy of the electronic scale.

[0042] The fault warning unit includes fault detection and alarm functions. Once a fault is detected, a fault signal is immediately sent to the control system. The control system displays the fault information and sounds an alarm through the human-computer interaction interface to remind the operator to perform repairs in time. At the same time, the system also records information such as the time, location and type of the fault to facilitate subsequent fault troubleshooting and maintenance.

[0043] The weight detection device module is electrically connected to the fault warning unit. By connecting the weight detection device module to the fault warning unit, the operating status of each component can be monitored in real time through the fault detection module during use.

[0044] The data acquisition module is electrically connected to the microprocessor, and the microprocessor is electrically connected to the control module. The data acquisition module transmits data to the microprocessor, and the microprocessor processes and analyzes the data and compares it with a preset weight threshold. If three grading channels are set, they correspond to high-quality seeds with a weight greater than threshold A, medium-quality seeds with a weight between threshold A and threshold B, and low-quality seeds with a weight less than threshold B.

[0045] The control module is electrically connected to the baffle, and the grading device module is electrically connected to the fault warning unit. When the microprocessor determines that the seed weight is greater than the threshold value A, it sends an instruction to the control module to control the baffle of the corresponding high-quality seed grading channel to open, and the seeds fall into the channel; if the seed weight is between the threshold value A and the threshold value B, the baffle of the medium-quality seed grading channel is controlled to open; if the seed weight is less than the threshold value B, the baffle of the low-quality seed grading channel is controlled to open.

[0046] As a preferred embodiment, the present invention comprises a bare soil vegetation restoration device for power line tower foundations in high altitude areas according to claims 1 to 7, further comprising:

[0047] S1. System installation: Install the feeding device, weight detection device, grading device and control system according to the design requirements, ensure that all components are firmly and stably connected, and connect the electrical circuits between the components, including the data transmission line between the weight detection device and the control system, and the control line between the control system and the grading device.

[0048] In S1, first, in the selected suitable site, according to the detailed design layout plan, the feeding device is accurately positioned and fixed. The hopper of the feeding device needs to be installed in a stable and convenient position for loading. The vibrating feeder is tightly connected to the hopper to ensure that it can effectively drive the seeds to fall evenly. The conveying pipeline connects the hopper and the weight detection device with an appropriate slope and direction to ensure that the seeds can be transmitted smoothly and stably. Then the weight detection device is installed. The device needs to be placed on a horizontal and stable base to avoid interference with the weight measurement due to external vibration or tilt. The scale pan of its high-precision electronic scale, that is, the special grid structure, must be ensured to be installed flat without any warping or depression, so that the seeds can be accurately placed on it for weight detection. Then the grading device is installed. Multiple grading channels need to be installed in an orderly manner according to the predetermined arrangement, and the precise spacing and angles between the channels are maintained to ensure that the seeds can be accurately placed on it. To prevent misjudgment or jamming of seeds during the diversion process, the corresponding baffle should be installed in the appropriate position, and the mechanical structure connected to the control system should be flexible and able to quickly respond to the instructions of the control system to achieve precise opening and closing. Finally, the control system should be installed, and the microprocessor, data acquisition module, control module and human-computer interaction interface should be properly placed in a special control box to protect them from environmental factors such as dust and moisture. The data transmission line between the weight detection device and the control system should be connected with shielded wires to avoid electromagnetic interference affecting the accuracy and stability of the data, ensuring that the weight data can be transmitted to the data acquisition module in real time and accurately. The control line of the control system and the grading device must be firmly connected to ensure that the control signal can be transmitted quickly and accurately, thereby accurately controlling the opening and closing of the baffle, so that the components of the entire system can work together to efficiently complete the seed screening task.

[0049] S2. System debugging: First, turn on the vibrating feeder of the feeding device, check the conveying condition of the seeds in the conveying pipe, adjust the vibration frequency and the slope of the conveying pipe so that the seeds can enter the weight detection device evenly and smoothly, then calibrate the weight detection device, place the standard weights on the scale pan, perform calibration operations according to the calibration procedure, ensure that the measurement accuracy of the electronic scale meets the requirements, finally, test the grading device, manually control the opening and closing actions of the baffles of each grading channel through the control system, and check its flexibility and accuracy.

[0050] In S2, first, the vibrating feeder of the feeding device is turned on, and the conveying of the seeds in the conveying pipeline is carefully observed. At the initial start-up, the vibrating feeder starts to vibrate at a lower preset frequency, and the seeds begin to slowly enter the conveying pipeline. At this time, the technicians pay close attention to the flow state of the seeds in the pipeline to check whether there is blockage, accumulation or uneven flow rate. If the seed flow rate is too fast, it may cause seed overlap at the weight detection device and affect the detection accuracy, or the flow rate is too slow to affect the overall screening efficiency. At this time, it is necessary to finely adjust the vibration frequency, with a small increase or decrease each time (such as an increase or decrease of 0. 5Hz), gradually find the most suitable vibration frequency value so that the seeds can travel in the conveying pipeline at a uniform and stable speed. At the same time, the slope of the conveying pipeline also needs to be accurately adjusted. With the help of tools such as a level, measure the horizontal deviation of different positions of the pipeline. According to the physical characteristics of the seeds (such as the size, shape, surface smoothness, etc. of the seeds) and the observed conveying conditions, fine-tune the supporting structure of the pipeline and change its slope. For example, if the seeds are prone to stagnation in a certain section of the pipeline, the slope of this section of the pipeline can be appropriately increased to allow the seeds to slide more smoothly under the action of gravity, but the adjustment of the slope should also avoid To avoid the seeds from sliding too fast and losing control due to the large weight, through continuous attempts and adjustments, the seeds can eventually enter the weight detection device evenly and smoothly, laying a good foundation for subsequent accurate weight detection. Then, calibrate the weight detection device and carefully place the standard weights that have been certified by a professional metrology agency and meet the accuracy requirements on the scale pan. Before placing the weights, ensure that the surface of the scale pan is clean and free of impurities to avoid affecting the contact accuracy between the weights and the scale pan. Follow the pre-set calibration procedure and start the calibration mode of the weight detection device. At this time, the display screen of the electronic scale will display relevant prompt information. The standard weight is placed in the center of the scale pan. The electronic scale will quickly sense the weight change and display the reading. The operator compares the reading displayed on the electronic scale with the actual weight value of the standard weight. If there is a deviation between the two, according to the guidance of the calibration procedure, the internal parameters of the electronic scale are adjusted by operating the calibration button in the control system or entering relevant calibration instructions. This adjustment may involve the correction of parameters such as sensor sensitivity and zero drift. Repeated measurement and adjustment operations are performed until the reading displayed on the electronic scale is completely consistent with the actual weight value of the standard weight or the error is controlled within a very small allowable range (such as ±0.01g), ensure that the measurement accuracy of the electronic scale meets the requirements, so as to ensure the accuracy and reliability of the subsequent seed weight detection data. Finally, test the grading device. Through the operation interface of the control system, manually input control instructions to control the opening and closing of the baffles of each grading channel. Before the test begins, check whether the appearance of the grading device is damaged or foreign objects hinder the normal movement of the baffles to ensure that each grading channel is unobstructed. When the instruction to open the baffle of a grading channel is issued, listen carefully to the mechanical sound when the baffle is opened, and observe whether the opening speed meets the design requirements, whether it can be opened quickly and smoothly to the predetermined position, and whether there is no jamming or abnormal shaking. Similarly, when the instruction to close the baffle is issued, When the baffle plate is instructed, check whether it can be tightly closed, whether it fits well with the edge of the channel, and whether there are any gaps that may cause seeds to flow into other channels by mistake. The baffle plates of each grading channel are repeatedly opened and closed for many times, and tested at different time intervals to check its flexibility and accuracy under long-term operation or different working conditions. At the same time, it is also possible to simulate the situation when seeds pass through, such as placing some objects simulating the weight of seeds on the scale of the weight detection device, allowing the system to run according to the normal process, and observe whether the grading device can accurately distribute these simulated seeds to the corresponding grading channels according to the set weight threshold, and further verify whether the performance of the grading device meets the expected standards. .

[0051] S3. Pour the seeds to be screened into the hopper of the feeding device, start the system, and the vibrating feeder starts working. The seeds enter the weight detection device through the conveying pipeline. The weight detection device detects the seeds one by one or in batches, and transmits the weight data to the control system. The control system controls the baffle action of the grading device according to the preset weight grading standard, and screens the seeds into different grading channels respectively. The screened seeds are collected in the collection containers of each grading channel. The operator can perform subsequent processing on seeds of different grades as needed, such as high-quality seeds for sowing, medium-quality seeds for further processing or for other purposes, and poor-quality seeds for elimination.

[0052] In S3, the seeds to be screened are carefully poured into the hopper of the feeding device to ensure that the hopper has enough capacity to accommodate the seeds and will not overflow. After starting the system, the vibrating feeder starts working immediately, making a slight and rhythmic humming sound. The internal vibrating components start to operate according to the preset initial vibration intensity and frequency. Under the action of vibration, the seeds in the hopper are gradually activated, loosened from each other, and begin to move slowly to the entrance of the conveying pipe. The seeds enter the weight detection device through the conveying pipe. The inner wall of the conveying pipe is specially smoothed to reduce the friction resistance of the seeds during transportation and ensure that the seeds can move forward smoothly. When the seeds arrive at the weight detection device, if the grain-by-grain detection method is adopted, each seed will accurately fall on the grid-shaped scale plate of the high-precision electronic scale of the weight detection device. The electronic scale is equipped with an extremely sensitive pressure sensor that can instantly sense the weight of the seeds and convert this weight data into an electrical signal. If it is a batch detection mode, after a certain number of seeds fall into the scale, the average weight of the batch of seeds and other related data information will be comprehensively calculated. Subsequently, these weight data will be quickly transmitted to the control system through a special data line in a high-speed and stable transmission method. After receiving the weight data, the control system will immediately conduct a fast and accurate analysis and judgment based on the preset weight classification standard. For example, if three levels of classification standards are set, for seeds whose weight exceeds the threshold of high-quality seeds, the control system will quickly send an opening command to the baffle of the high-quality seed channel in the grading device. The command is accurately transmitted through the control line. The corresponding baffle is driven by the motor drive or electromagnetic control device at the moment of receiving the command, and opens quickly and smoothly. The seeds will fall smoothly into the grading channel of high-quality seeds under the action of gravity. Similarly, for seeds whose weight is within the threshold range of medium-quality seeds, the control system will control the baffle of the medium-quality seed grading channel to open, allowing them to enter the channel;Seeds with a weight lower than the threshold of inferior seeds will be screened to the inferior seed grading channel. The screened seeds will be collected in the collection containers of each grading channel. These collection containers are placed below the end outlet of the grading channel. They are made of durable materials and have good sealing properties, which can effectively prevent seeds from scattering during the collection process. Operators can perform subsequent processing on seeds of different grades as needed. High-quality seeds will be carefully selected for sowing due to their good germination potential and growth vitality, providing a solid foundation for high yield and high-quality growth of crops. Although medium-quality seeds are slightly inferior in some aspects, they still have certain utilization value and can be further processed, such as being strengthened by special cultivation technology before being used for sowing, or used in some agricultural experiments or affiliated planting projects that have relatively low requirements for seed quality. Inferior seeds, due to their defects such as low germination rate and poor growth, will be decisively eliminated to avoid wasting land resources and agricultural input costs, such as centralized destruction or other environmentally friendly treatment methods, to ensure the efficiency and economy of the entire agricultural production process. ;

[0053] S4. Regularly perform maintenance on the system, clean the residual seeds and impurities in the feeding device, weight detection device and grading device to prevent them from affecting the operation of the system, check whether the connection parts of each component are loose, whether the electrical circuit is damaged, if there is any problem, tighten and repair it in time, calibrate the weight detection device regularly to ensure the stability of its measurement accuracy, at the same time, check the fault records of the system, focus on the inspection and maintenance of the faulty parts that have occurred before, and prevent the fault from happening again.

[0054] In S4, regular comprehensive and detailed maintenance of the system is the key to ensure its continuous and stable operation. First of all, for the feeding device, the inside of the hopper needs to be thoroughly cleaned. During the seed feeding process, some seeds may be broken due to collision and friction, and the resulting debris and impurities such as dust and soil mixed in the seeds will remain at the bottom and wall of the hopper. The technicians will use special cleaning tools, such as small shovels, brushes, etc., to carefully remove and clean these residual materials to ensure that the inner surface of the hopper is smooth and free of foreign matter to avoid affecting the normal feeding of subsequent seeds. For the vibrating feeder, check whether there is any debris entangled around the vibration spring. If there is, clean it carefully to prevent it from interfering with the normal expansion and contraction of the spring, thereby affecting the vibration frequency and The feeding effect and the conveying pipeline cannot be ignored. Use a compressed air spray gun to blow from one end of the pipeline to the other end to blow out the tiny seed particles and dust that may be attached to the inner wall of the pipeline to ensure the patency of the inside of the pipeline so that the seeds can pass smoothly and unimpeded. In terms of the weight detection device, the grid structure of the scale pan of its high-precision electronic scale is prone to accumulate some fine seed residues and dust. The staff will use a soft brush to gently clean the surface of the scale pan to remove these impurities to prevent them from interfering with the accuracy of weight measurement. At the same time, check whether there is any foreign matter attached to the sensor part of the electronic scale. If there is, use a clean soft cloth to dip in a small amount of anhydrous ethanol and wipe it carefully to ensure that the sensor can accurately sense the weight change. For the shell and peripheral connections of the electronic scale, The components should also be cleaned and inspected to see if there is corrosion or stains caused by environmental factors. If so, they should be dealt with in time. The cleaning of the grading device is equally important. Some seeds that have not been completely collected may remain in each grading channel. The technicians will open the channels one by one and manually clean the seeds and other possible impurities in them to ensure that the inside of the channel is clean and tidy to avoid the accumulation of seeds in the channel and affect the diversion effect during the next screening. Check whether the edge of the baffle of the grading channel is worn or deformed. If such problems exist, the baffle may not be closed tightly, causing the seeds to flow into the wrong channel. For the driving mechanism of the baffle, such as the motor, transmission chain or electromagnetic device, check whether there is oil or dust accumulation, clean it and add an appropriate amount of lubricating oil , to ensure its smooth operation. When checking the connection parts of each component, the technicians will carefully inspect along the various structural components of the system. For the connection flange between the feeding device and the conveying pipeline, use a wrench to check whether the bolts are loose. If they are found to be loose, tighten them according to the specified torque value to ensure that the connection is tight and there is no leakage. At the connection between the weight detection device and the conveying pipeline and the control system, check whether the data cable interface is loose, whether the connector of the electrical circuit is oxidized or has poor contact. If there is a problem, re-plug or replace the connector in time. For the control line connection points between the grading device and the control system, also conduct a detailed inspection to ensure that the line connection is stable and reliable, and the signal transmission is normal. When checking whether the electrical circuit is damaged, follow the direction of the line,Check whether the insulation skin has scratches, wear, aging, cracks, etc., especially at sharp corners or frequently active parts. Once the line is found to be damaged, according to the degree of damage, it can be repaired by wrapping with insulating tape if it is minor, or it is necessary to replace the damaged line section if it is serious, to prevent safety accidents caused by line leakage or short circuit and affect the normal operation of the system. Regular calibration of the weight detection device is a necessary means to maintain its high-precision measurement. The calibration process is strictly carried out in accordance with the equipment operation manual. First, prepare a set of standard weights calibrated by a professional metrology agency and with higher accuracy than this weight detection device. The range of the weights should cover the daily detection types of the system. Place the weight detection device on a stable platform without vibration interference, turn on the device and preheat it for a period of time to make it reach a stable working state, then place standard weights of different weights on the center of the scale pan in turn. After placing the weights each time, wait for the electronic scale reading to stabilize and record the displayed weight value. Compare the recorded measured value with the actual value of the standard weight and calculate the error range. If the error exceeds the allowable accuracy range, adjust the internal parameters of the electronic scale through the calibration menu of the weight detection device or the calibration program in the control system, such as zero point calibration, gain adjustment, etc. Repeat the above calibration steps again after adjustment until the measurement is stable. The measurement error is controlled within the specified accuracy range to ensure the stability of its measurement accuracy, thereby providing a reliable basis for seed screening. At the same time, the system's fault records should be carefully checked. The system's control system usually automatically records each fault information, including the time of the fault, the specific fault location, the fault type, and the relevant fault code and other detailed data. According to these fault records, the technicians focus on the inspection and maintenance of the parts where the fault has occurred. For example, if there is a record showing that the sensor of the weight detection device has had an abnormal signal failure, then in this maintenance, in addition to the routine cleaning and inspection of the sensor, professional testing instruments will be used to conduct detailed tests on the performance parameters of the sensor, such as measuring the linearity and repeatability of its output signal, to determine whether the sensor has potential performance degradation problems. For parts where line connection failures have occurred, the inspection frequency of the line will be increased, and connection components that may have hidden dangers, such as wiring terminals and plugs, will be replaced. For the problem of baffle action jamming in the grading device, in addition to checking the baffle itself and its driving mechanism, the relevant control circuit and the program module that controls the baffle action in the control system will be checked and optimized to prevent the failure from happening again and ensure that the system can operate stably and efficiently for a long time. ,
