Description

Technical Field

[0001] This application relates to the field of grain and oilseed storage technology, and in particular to a grain and oilseed drying, storage and disinfection device. Background Technology

[0002] Grain and oilseed storage is of great significance for agricultural production, food security, biodiversity conservation, and economic development. Grain and oilseed storage ensures a sufficient supply of seeds under different seasons and climatic conditions, guaranteeing the continuity and stability of grain production. By storing different types and varieties of grain and oilseeds, agricultural biodiversity can be protected and preserved, preventing variety extinction. High-quality seeds are the foundation for improving crop yield and quality. Good seed storage conditions ensure seed viability and health, thereby enhancing the growth potential of crops.

[0003] In the event of natural disasters such as floods, droughts, and outbreaks of pests and diseases, grain and oilseed storage serves as an important backup resource, helping farmers quickly resume production. Proper storage and management of seed resources can reduce seed waste and improve the sustainability of agricultural production. High-quality grain and oilseeds can enhance the market competitiveness of agricultural products and increase farmers' income. Seed storage can regulate market supply and demand, prevent seed shortages caused by seasonal or regional factors, and maintain stable seed prices.

[0004] The methods of grain and oil storage include the following:

[0005] 1. Dry storage: By reducing the moisture content of grains and oils, the growth of microorganisms and the respiration of grains and oils are inhibited, thereby extending the storage period.

[0006] 2. Ventilation and airtight storage: This includes natural ventilation and mechanical ventilation. Natural air convection or the use of fans facilitates gas exchange to achieve cooling and moisture dissipation. Airtight storage involves completely sealing the storage area or covering the grain surface to prevent external heat and moisture from penetrating the grain pile.

[0007] 3. Low-temperature storage: This involves controlling the temperature of grains and oils to a low level to limit biological activity, reduce losses, and maintain quality. Low-temperature storage methods include natural low-temperature storage, mechanical refrigeration low-temperature storage, and underground storage.

[0008] 4. Controlled atmosphere storage: By adjusting the gas composition inside a sealed grain pile, mainly by reducing oxygen or increasing carbon dioxide concentration, biological activity inside the grain pile is inhibited, thereby achieving the purpose of safe storage.

[0009] 5. Chemical storage: Chemical agents are used to inhibit the life activities of grains, oils, and microorganisms, prevent heating and mold growth, and eliminate stored grain pests. Commonly used chemical preservatives include propionic acid and sorbic acid.

[0010] However, existing technologies have many problems. 1. Insufficient research on local grain condition changes and control technologies: There is a lack of in-depth and systematic research on micro-airflow in grain piles, heat and moisture transfer in grain piles, and their impact on quality and control technologies; in production, there are few local ventilation methods, and the operation is time-consuming, labor-intensive, and inefficient. 2. The impact of seed self-heating: During storage, seeds continuously release moisture and heat to the outside environment. If the ventilation of the storage space is poor, the moisture and heat released by the seeds cannot be discharged in time, which aggravates the heat loss from the seeds, leading to the growth and reproduction of microorganisms and causing quality changes. 3. Pest problems: Pests carried by the seeds themselves or present in the storage environment can cause seed damage, affecting the germination rate. Summary of the Invention

[0011] The purpose of this application is to overcome the problems of lack of local ventilation methods and difficulty in actively cleaning local pests in the existing technology, and to provide a grain and oil seed drying, storage and pest control device.

[0012] Firstly, a grain and oil seed drying, storage, and disinfection device is provided, comprising:

[0013] The housing has an air intake grille installed at its upper end, an air outlet grille and a quick connector installed on the lower side wall of the housing, a fan installed between the air outlet grille and the air intake grille, and an infrared sensor installed on the side wall of the housing.

[0014] A plasma generator, which is installed between the fan and the air intake grille;

[0015] A walking assembly, which is mounted on the underside of the housing;

[0016] A pest locating device includes a microphone array connected to an audio analog-to-digital converter, the audio analog-to-digital converter being electrically connected to a signal processing unit, and the signal processing unit being electrically connected to a computing unit. The computing unit is used to locate the position of a sound source and send it to a control module.

[0017] The control module is electrically connected to the power supply module, and the fan, infrared sensor, plasma generator, and walking assembly are all connected to the control module.

[0018] In some possible implementations, the air intake grille is equipped with a filter screen, which can filter the air entering through the air intake grille to prevent flying insects from entering the disinfection equipment.

[0019] In some possible implementations, the air outlet grille includes a rotatable horizontal grille, a rotatable vertical grille, a first actuator for driving the horizontal grille to rotate, and a second actuator for driving the vertical grille to rotate. By controlling the rotation of the horizontal grille, the up-and-down sweeping of the air outlet can be controlled. By controlling the rotation of the vertical grille, the left-and-right sweeping of the air outlet can be controlled. The cooperation of the horizontal and vertical grilles can blow air to disinfect pests in a designated area, thereby improving the efficiency of pest control in the pest area.

[0020] In some possible implementations, the walking assembly includes at least one drive wheel, at least one driven wheel, a first power source for driving the drive wheel to rotate, and a second power source for driving the drive wheel and / or the driven wheel to turn. Both the first and second power sources are electrically connected to the control module. By controlling the rotation and direction of the drive wheel, the disinfection equipment can be driven to move and, in conjunction with an infrared sensor, obstacle avoidance can be achieved during the movement, thereby moving the disinfection equipment to a designated location.

[0021] In some possible implementations, the power supply module includes a DC power supply and a pulse power supply.

[0022] In some possible implementations, the pulse width generated by the pulse power supply is on the order of nanoseconds.

[0023] In some possible implementations, the pest locating device communicates with the control module wirelessly.

[0024] In some possible implementations, the quick connector is equipped with an electric valve that is electrically connected to the control module.

[0025] In some possible implementations, the plasma generator includes multiple discharge electrode lines.

[0026] In some possible implementations, the control module is a PLC controller.

[0027] This application has the following beneficial effects:

[0028] 1. This application can use a pest locator to locate pests based on the sounds they make. By controlling the movement of the walking components, the application can move the pest control equipment to the location of the pests. Combined with an infrared sensor, it can accurately locate the pest activity area. By aiming the air outlet grille at the pest activity area, it can disinfect pests by using ozone generated by ionizing the air. At the same time, it can use a plasma generator to discharge and ionize the air to purify the surrounding air. Furthermore, it can use an infrared sensor to detect the survival status of pests. Once all pests in the activity area are killed, it can move to the next location for further pest control. It can also control the pest control equipment to move within the grain warehouse when there are no pests, using a plasma generator to discharge and ionize the air to purify pathogens, bacteria, and other substances that are detrimental to seed storage.

[0029] 2. By setting up an infrared sensor, this application can not only use the infrared sensor to avoid obstacles during the movement of the pest control equipment, but also use the infrared sensor to identify the survival rate of pests in a designated area, thereby controlling the power of the plasma generator and the duration of pest control based on the survival rate of pests.

[0030] 3. This application can also connect to a seed dryer via a quick connector before seed storage, and deliver plasma air into the dryer to disinfect pathogens and bacteria on the seed surface, which is beneficial for seed storage. Attached Figure Description

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example

[0045] like Figures 1-4As shown in the figure, a grain and oil seed drying, storage, and disinfection device according to an embodiment of this application includes a housing 100. Air inlet grilles 101 are installed around the upper perimeter of the housing 100. To prevent flying insects, large particles, and other impurities from entering the housing 100 through the air inlet grilles 101, a filter screen 106 is installed inside the air inlet grilles 101. An air outlet grille 102 and a quick connector 103 are installed on the lower side wall of the housing 100. The quick connector 103 is used to connect to a seed dryer to introduce ionized air (containing a large number of negative air ions and trace amounts of ozone) into the seed dryer. A fan is installed between the air outlet grille 102 and the air inlet grille 101. The fan 104 is a small axial flow fan. The fan 104 can draw air from the gap outside the housing 100 into the housing 100 through the air inlet grille 101 and discharge it from the air outlet grille 102 or quick connector 103 as needed. An infrared sensor 105 is installed on the side wall of the housing 100. The infrared sensor 105 can be set at the front end of the pest control equipment 700. When moving, the infrared sensor 105 can be used to identify obstacles and avoid them. Alternatively, the infrared sensor 105 can be set on the plane where the air outlet grille 102 is located. After reaching the location of the pest, the infrared sensor 105 can be used to identify the specific location of the pest and the number of pests.

[0046] like Figure 2 , Figure 3 and Figure 6 As shown, the quick connector 103 is equipped with an electric valve 107. The electric valve 107 is electrically connected to and controlled by the control module 500. During routine disinfection of the grain silo 800, the electric valve 107 is closed, allowing air in the housing 100 to be discharged through the exhaust grille 102. When the disinfection equipment 700 is combined with the dryer, the electric valve 107 of the quick connector 103 opens and controls the exhaust grille 102 to close, as shown. Figures 5-6As shown, the exhaust grille 102 includes a rotatable horizontal grille 1021, a rotatable vertical grille 1023, a first actuator 1022 for driving the horizontal grille 1021 to rotate, and a second actuator 1024 for driving the vertical grille 1023 to rotate, such that the exhaust grille 102 is divided into two layers. The outer layer is the horizontal grille 1021, which is driven by the first actuator 1022 and can swing up and down, and the inner layer is the vertical grille 1023, which is driven by the second actuator 1024 and can swing left and right. The first actuator 1022 and the second actuator 1024 can be power devices such as motors, electric actuators, or cylinders. When air needs to be discharged from the quick connector 103, the exhaust grille 102 can be closed by controlling the horizontal grille 1021 and the vertical grille 1023 to prevent air leakage. And when the disinfection equipment 700 moves to After designating a specific area (the designated area is the target location for the pest control device 700 to move to, as specified by the control module 500 based on the location of the pests located by the pest positioning device 400), the area is detected using the infrared sensor 105. By adjusting the rotation angle of the horizontal grille 1021 and the vertical grille 1023, the air blown out by the exhaust grille 102 can be concentrated and directed towards the area with pests. This allows for more targeted airflow to eliminate pests in the designated area. Furthermore, the infrared sensor 105 can be used to identify the survival status of the pests, and the timing for stopping the pest control can be determined based on their survival status. If the area with pests is large, the vertical grille 1023 and / or the horizontal grille 1021 can be controlled to swing back and forth to achieve reciprocating pest control over a large area. At the same time, the power of the plasma generator 200 can be increased to improve the pest control efficiency in large areas.

[0047] like Figure 4 The diagram shows a cross-sectional view of the disinfection device 700, which includes a plasma generator 200. The plasma generator 200 is installed between the fan 104 and the air intake grille 101. The plasma generator 200 includes multiple discharge electrode wires and is powered by a pulse power supply 602 provided by a power module 600. The discharge electrode wires discharge and ionize the air to generate a large number of negative air ions and a trace amount of ozone, which can purify the air and use ozone to sterilize and kill pests.

[0048] The walking assembly 300 is installed below the housing 100. The walking assembly 300 includes at least one drive wheel 301, at least one driven wheel 302, a first power source 303 for driving the drive wheel 301 to rotate, and a second power source 304 for driving the drive wheel 301 and / or the driven wheel 302 to turn. Both the first power source 303 and the second power source 304 can be motors. For example, one drive wheel 301 and two driven wheels 302 can be provided, and the direction of the disinfection device 700 can be achieved by controlling the direction of the drive wheel 301. Alternatively, two drive wheels 301 and two driven wheels 302 can be provided, and the direction of the disinfection device 700 can be achieved by controlling the direction of the drive wheel 301, or by controlling the direction of the driven wheels 302. The steering mechanism enables the pest control device 700 to turn. The number of driven wheels 302 and drive wheels 301 can be customized. The steering can be performed by drive wheels 301 or driven wheels 302, or both drive wheels 301 and driven wheels 302 can turn. There is no limitation here. The first power source 303 and the second power source 304 are both electrically connected to the control module 500 so that the control module 500 can control the drive wheels 301 to move and turn. Based on the obstacle information provided by the infrared sensor 105 and the pest location provided by the pest positioning device 400, the walking component 300 is controlled to move the pest control device 700 to the designated location, i.e., near the pest location, so that the air blown out by the exhaust grille 102 can reach the pest location to disinfect the pest.

[0049] like Figure 7 As shown, a pest locating device 400 is included. The pest locating device 400 includes a microphone array 401, which is connected to an audio analog-to-digital converter 402. The audio analog-to-digital converter 402 is electrically connected to a signal processing unit 403, which is electrically connected to a computing unit 404. The computing unit 404 is used to locate the position of the sound source and send it to the control module 500.

[0050] Specifically, the microphone array 401 consists of multiple microphones arranged around the seed pile. The microphone array 401 can be designed as a three-dimensional structure to capture sound signals generated by pest activity. The number of microphones depends on the number of seed piles. Multiple microphones cover different areas of the grain silo 800. Different types of pests produce sounds with specific frequencies, intensities, and temporal characteristics during their activity, allowing for more comprehensive monitoring of pest activity. The audio analog-to-digital converter 402 converts the analog sound signals captured by the microphones into digital signals. The signal processing unit 403 then processes the signals captured by the microphone array 401, including signal amplification, filtering, and analog-to-digital conversion. Finally, a computing unit 404 calculates the location of the sound source. The computing unit 404 is typically an embedded system or computer used to run a sound source localization algorithm to calculate the location of the sound source. By comparing the signals received by different microphones and calculating the time difference of sound arrival at each microphone, the location of one or more sound sources within the grain silo 800 can be determined.

[0051] like Figure 6 As shown, the control module 500 is electrically connected to the power supply module 600. The fan 104, infrared sensor 105, plasma generator 200, and walking assembly 300 are all connected to the control module 500. The control module 500 is also electrically connected to a self-positioning module 108 for locating the position of the disinfection equipment 700. The control module 500 is a PLC controller, and the self-positioning module 108 is a GPS positioning module. The power supply module 600 includes a DC power supply 601 and a pulse power supply 602. The DC power supply 601 includes a low-voltage DC power supply 601 and a high-voltage DC power supply 602. The low-voltage DC power supply 601 powers the PLC controller and the fan. 104. The infrared sensor 105 and drive components are powered by a high-voltage DC power supply 601, which powers the plasma generator 200. The pulse power supply 602 generates pulses with a pulse width in the nanosecond range and powers the plasma generator 200. When the pest locating device 400 detects the location of the pest emitting an acoustic signal, it sends the location information to the control module 500 wirelessly. The wireless communication method can be a local area network, Bluetooth, or other wireless communication methods. After receiving the location information of the pest, if there are multiple pest activity locations at the same time, the control module 500 will label these locations so that the pests can be eliminated in the order of the labels.

[0052] For example, such as Figure 8As shown, multiple independent piles 900 of bagged seeds are stacked in the grain silo 800. Each pile 900 consists of multiple woven bags containing seeds. When a pest locating device 400 detects pest activity in a particular pile of seeds 900, it sends the location information of that pile to the PLC controller. The PLC controller, based on the location of the pest control device 700 obtained by its own positioning module 108 and a pre-modeled map of the grain silo 800, controls the operation of the first power source 303 and the second power source 304. It also utilizes the obstacle detection capability of the infrared sensor 105 and the obstacle avoidance program of the PLC controller to implement obstacle avoidance logic. When the infrared sensor 105 detects an obstacle, the PLC controller controls the pest control device 700 to stop, reverse, or turn according to a preset obstacle avoidance strategy to avoid collisions, moving the pest control device 700 to the appropriate location, i.e., next to the pile of seeds. Next, the infrared sensor 105 detects the area of ​​pest activity on the seed pile, and controls the electric valve 107 of the quick connector 103 to close. Then, the first driver 1022 and the second driver 1024 are controlled to direct the air outlet grille 102 towards the area of ​​pest activity, and the ozone generated by the plasma generator 200 ionizes the air is used to disinfect the pests in the targeted area. When there are many locations of pests in the grain silo 800, the pests are disinfected in a cyclical manner in these locations. After the pests are disinfected, the pest control equipment 700 turns on the ozone removal mode, and the high-voltage DC power supply 601 powers the plasma generator 200 to remove the ozone in the air. That is, under a low electric field strength (2000-3800V / cm), it continues to discharge to generate free electrons. The energy field is low, but it still meets the electron energy required for ozone decomposition, so it can decompose ozone. In order to detect the ozone concentration, an ozone detector can be installed in the grain silo 800 or on the pest control equipment 700 and circulate throughout the grain silo 800. Simultaneously, based on data from different ozone detectors, the dwell time at a specific point is increased to achieve more efficient and uniform ozone removal. When there are no pests in grain silo 800, the pest control equipment 700 moves back and forth in grain silo 800 according to obstacle avoidance logic, purifying carbon dioxide, bacteria, and other substances detrimental to storage caused by seed respiration.

[0053] In this embodiment, artificial intelligence can also be embedded. Based on the data fed back by the infrared sensor 105, the disinfection time and intensity can be adjusted according to the degree of insect outbreak, within a set cycle. When frequent insect activity is detected, a strong disinfection mode is activated, that is, the power of the plasma generator 200 is appropriately increased to generate more ozone for powerful insect elimination. If insects begin to appear but have not yet broken out, a suppression mode is activated, that is, the power of the plasma generator 200 is appropriately reduced to inhibit insect growth and reproduction. If there are no insects in the grain silo 800, an air purification mode is activated, that is, the disinfection device 700 circulates within the grain silo 800, using the plasma generator 200 to ionize and purify the air, ensuring the freshness of the gas within the grain silo 800. When using the infrared sensor 105 to identify the survival status of pests, moisture has an absorption effect on near-infrared waves. The water content of dead insects is lower than that of live insects. Utilizing this characteristic, multi-band information fusion is used to extract sensitive spectral band image features that can effectively determine the activity of grain insects, solving the problem of distinguishing between live and dead insects. Adjust the duration of the strong pest control mode based on the ratio of dead to live insects until the ratio of live insects approaches 0.

[0054] like Figures 2-3 As shown, the disinfection equipment 700 is equipped with a quick connector 103, allowing for perfect integration with seed storage processes. Before seed storage, the seeds are dried. The disinfection equipment 700 can be integrated with the dryer without damaging its original structure and process. It is only installed at the emergency unloading port. During the drying process, a plasma air stream is introduced, ensuring full contact between the plasma air and the seeds, eliminating pathogens and bacteria on the seed surface while drying. After drying, the disinfection equipment 700 is moved into the grain silo 800 for purification and disinfection. The quick connector 103 has an electric valve 107, which is closed in the grain silo 800. The exhaust grille 102 is closed when connected to the dryer, allowing for control over whether air is emitted from the exhaust grille 102 or the quick connector 103 as needed.

[0055] The above are merely preferred embodiments of this application; however, the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.
