Description

Technical Field

[0001] The invention belongs to the technical field of agricultural production equipment, and in particular relates to a continuous eddy current seed soaking device and method. Background Art

[0002] In the fields of seed sowing and sprout production, it is often necessary to soak the seeds of fruits and vegetables in advance before sowing to promote rapid germination of the seeds. Especially in the field of sprout production, most seeds need to be soaked to ensure the germination rate and germination rate.

[0003] The existing seed soaking process is mostly done manually, directly immersing the seeds into the corresponding water and then fishing them out, which is inconvenient to operate. This will make the seed soaking efficiency low and is not conducive to agricultural work. This requires the use of automatic seed soaking equipment.

[0004] For example, a Chinese patent with patent publication number CN221081955U discloses a fully automatic seed soaking device, including a base, two symmetrically arranged support seats are fixedly connected to the upper end surface of the base, and support shafts are rotatably connected on the side walls of the two support seats close to each other, and the two support shafts are commonly fixedly connected to a working cylinder, and a working component is arranged in the working cylinder, one of the support seats is provided with a flip motor, and the output end of the flip motor is fixedly connected to one of the support shafts, an opening is provided on a side wall of the working cylinder away from the base, and the opening is arranged away from the two support shafts, a working motor is provided on the outer wall of the working cylinder away from the two support shafts, a working motor is provided on the working motor, and the working shaft passes through the working cylinder, and a stirring component is fixedly connected to the working shaft.

[0005] Although the above equipment can automatically complete the work of soaking seeds, taking and placing seeds, and greatly reduces the labor, the above equipment still has many shortcomings: Firstly, the above equipment lacks the means to accurately monitor and adjust the water saturation of seeds, which may easily lead to insufficient or excessive soaking of seeds.

[0006] Secondly, the equipment cannot maintain water quality, so the water needs to be replaced repeatedly during the seed germination process, which increases manual labor and increases labor costs.

[0007] Thirdly, water tends to become sticky when left standing for a long time. This sticky water will have adverse effects on the seeds when used for seed cultivation, especially it will easily damage the seed embryo. Once the seed embryo is damaged, the germination rate of the seed will be reduced, seriously affecting the normal germination and subsequent growth and development of the seed. Summary of the invention

[0008] The main technical problem to be solved by the present invention is to provide a continuous automatic seed soaking equipment and method, so as to accurately control the water saturation of seeds and ensure the optimal soaking state, while maintaining stable water quality to provide a healthy environment for seeds, reduce the risk of damage, and improve the germination rate and seedling health.

[0009] In order to solve the above technical problems, the present invention provides the following technical solutions: A continuous vortex seed soaking device comprises a seed soaking bin, wherein a feed port and a discharge port are respectively provided at the top and the bottom of the seed soaking bin, a counting assembly is provided at positions near the feed port and the discharge port on the outer wall of the seed soaking bin, a vortex outlet pipe is provided at a position near the discharge port on the inner wall of the bottom of the seed soaking bin, an overflow pipe is fixedly provided concentrically in the vortex outlet pipe, and the top of the overflow pipe is higher than the top of the vortex outlet pipe by a certain distance, a filter screen is provided at the top of the overflow pipe to prevent seeds from overflowing, and the outer side of the vortex outlet pipe is circular A plurality of spoilers are symmetrically arranged, and the flow-blocking surfaces of the spoilers are inclined along the tangent direction of the vortex in the seed soaking bin and toward the central axis direction of the seed soaking bin; a conical feed guide plate is arranged in the seed soaking bin directly below the feed port, and the feed guide plate is located directly above the vortex outlet pipe; the maximum diameter of the feed guide plate is larger than the diameter of the vortex outlet pipe; a screening component for separating soaked seeds from impurities is arranged below the seed soaking bin, and a circulating vortex component is arranged between the seed soaking bin and the screening component.

[0010] The following is a further optimization of the above technical solution by the present invention: The screening component includes a screening box, which is a hollow structure with an opening at the top. The top of the screening box is arranged downwardly at an inclination. A seed screening grille is arranged obliquely in the screening box, and the inclination direction of the seed screening grille is the same as the inclination direction of the top of the screening box. A seed discharge port is opened on the screening box near the inclined bottom end of the seed screening grille, and a seed collecting box is arranged on the outer wall of the screening box near below the seed discharge port.

[0011] Further optimization: a filter grille is obliquely arranged in the screening box and below the seed screen grille, the inclination direction of the filter grille is opposite to the inclination direction of the top of the screening box, and a debris removal port is arranged on the outer wall of the screening box near the inclined bottom end of the filter grille.

[0012] Further optimization: the outer side wall of the screening box is located below the impurity removal port and is fixedly connected to an automatic water replenishment valve, which is connected to an external water supply device.

[0013] Further optimization: a return pipe is fixedly connected to the bottom of the screening box, and the other end of the return pipe is connected to the circulating vortex component.

[0014] Further optimization: the circulating vortex component includes a circulating water pump, the water inlet end of the circulating water pump is fixedly connected to the return pipe, the water outlet end of the circulating water pump is connected to a water pipe, and the other end of the water pipe passes through the outer wall of the seed soaking bin and is connected to the seed soaking bin.

[0015] Further optimization: a water inlet is formed at the place where the water delivery pipe is connected to the seed soaking bin, the center line of the water inlet is tangent to the inner wall of the seed soaking bin, and the water inlet is higher than the top of the overflow pipe by a certain distance.

[0016] Further optimization: the counting component includes a feed counting grating arranged near the feed port and a discharge counting grating arranged near the discharge port; the feed counting grating is formed by multiple groups of parallel infrared beam emitters and corresponding multiple groups of infrared beam receivers to form an equidistant infrared beam grid located at the feed port, and the feed counting grating gap is approximately 0.5 times the minimum diameter of unsoaked seeds; the discharge counting grating is formed by multiple groups of parallel infrared beam emitters and corresponding multiple groups of infrared beam receivers to form an equidistant infrared beam grid located at the feed port, and the discharge counting grating gap is approximately 0.5 times the minimum diameter of soaked seeds.

[0017] Further optimization: the top of the spoiler is lower than the top of the overflow pipe and higher than the top of the vortex outlet pipe, and the bottom of the spoiler is lower than the top of the vortex outlet pipe.

[0018] The present invention also provides a method for using the continuous eddy current seed soaking device, based on the above-mentioned continuous eddy current seed soaking device, according to the following steps: S1. Equipment installation and commissioning: Ensure that the automatic water supply valve, circulating water pump, feed counting grating, discharge counting grating and other components are working properly; S2, water replenishment and start-up circulation: the automatic water replenishment valve replenishes water to the screening box to the control liquid level, and at the same time starts the circulating water pump to send the water in the screening box to the seed soaking bin; S3, liquid level control: when the water level in the seed soaking bin reaches the water outlet at the top of the vortex outlet pipe, if the water inflow is greater than the water outflow, the liquid level in the bin continues to rise to the top of the overflow pipe and overflows, so that the liquid level in the seed soaking bin and the screening box is stable; S4. Vortex formation and control: The circulation water pump runs to make water enter the seed soaking chamber in a specific direction to form a vortex, and the vortex angular velocity can be controlled by adjusting the frequency of the water pump motor; S5. Increase the oxygen content of the vortex: The water flowing out of the water inlet produces a Venturi effect in the seed soaking chamber, driving air into the vortex to generate bubbles, increasing the oxygen content of the vortex to inhibit the growth of anaerobic bacteria and prevent the water from becoming acidic and deteriorating; S6, seed soaking process: unsoaked seeds enter from the feed port, fall into the water through the feed guide plate and soak, the unsoaked seeds move with the vortex at the bottom and side wall of the soaking bin, and after the soaking is completed, the position changes due to the change in density, and moves to the spoiler, is guided to the vortex outlet pipe and falls into the screening box; S7, Feedback of discharging: The discharging counting grating measures the number of outflowing seeds and feeds back to the feeding system to replenish seeds. At the same time, the feeding counting grating measures the number of incoming seeds to ensure that the number of seeds in the soaking bin continues to match the carrying capacity of the soaking bin; S8, screening and water circulation: The soaked seeds are blocked by the grille in the screening box and slide down to the next process. The outflowing water returns to the bottom of the screening box after the seeds and impurities are screened out by the filter grille, and then pressurized by the circulating water pump and sent back to the seed soaking bin for recycling.

[0019] The present invention adopts the above technical solution and has the following beneficial effects: 1. The present invention arranges counting components near the feed port and the discharge port, so as to monitor the seed input and output in real time, and then can roughly estimate the residence time of the seeds in the seed soaking bin by comparing the amount of feed and discharge, and then adjust the feed speed according to the characteristics of different seeds and the required soaking time to ensure that the seeds have enough time to fully absorb water and reach the appropriate water saturation.

[0020] 2. The present invention arranges an overflow pipe concentrically in the vortex outlet pipe, and the top of the overflow pipe is higher than the top of the vortex outlet pipe by a certain distance, which is conducive to the formation of a stable vortex in the seed soaking liquid in the seed soaking bin, so that it circulates and rotates along a specific path. This vortex motion can allow the seeds to fully roll in the seed soaking liquid, ensuring that the seeds are in full contact with the seed soaking liquid, improving the uniformity and efficiency of seed soaking, and promoting the penetration of the seed soaking liquid for seeds with hard shells or thick seed coats, which is conducive to the absorption of beneficial ingredients; in addition, the filter screen at the top of the overflow pipe can prevent seeds from overflowing, ensuring that the seeds are soaked in the seed soaking bin, avoiding seed loss and blockage of the circulation system.

[0021] 3. The present invention can generate a stable vortex through a circulating vortex component, so that the seeds are continuously tumbled and stirred in the seed soaking solution, so that the contact degree between the seeds and the seed soaking solution can be controlled by adjusting the intensity of the vortex, thereby affecting the water saturation of the seeds.

[0022] 4. The present invention screens the soaked seeds through the screening component and can filter out impurities in the soaking liquid to prevent the accumulation of impurities and affect the water quality.

[0023] 5. By adopting the above technical scheme, the present invention can accurately control the water saturation of seeds, ensure the optimal seed soaking state, and at the same time maintain stable water quality to provide a healthy environment for seeds, reduce the risk of damage, and improve the germination rate and seedling health.

DETAILED DESCRIPTION

[0028] 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.

[0029] like Figure 1-9As shown, a continuous vortex seed soaking device comprises a seed soaking bin 1, wherein a feed port and a discharge port are respectively provided at the top and the bottom of the seed soaking bin 1, a counting assembly 2 is provided at positions near the feed port and the discharge port on the outer wall of the seed soaking bin 1, a vortex outlet pipe 3 is provided at a position near the discharge port on the bottom inner wall of the seed soaking bin 1, an overflow pipe 4 is fixedly provided concentrically in the vortex outlet pipe 3, and the top of the overflow pipe 4 is higher than the top of the vortex outlet pipe 3 by a certain distance, a filter screen 5 is provided at the top of the overflow pipe 4 to prevent seeds from overflowing, and the outer side of the vortex outlet pipe 3 is circular A plurality of spoilers 6 are symmetrically arranged around the seed soaking bin 1, and the flow-blocking surface of the spoiler 6 is inclined along the tangent direction of the vortex in the seed soaking bin 1 and toward the central axis direction of the seed soaking bin 1; a conical feed guide plate 7 is arranged in the seed soaking bin 1 just below the feed port, and the feed guide plate 7 is located just above the vortex outlet pipe 3; the maximum diameter of the feed guide plate 7 is larger than the diameter of the vortex outlet pipe 3; a screening component 8 for separating soaked seeds from impurities is arranged below the seed soaking bin 1, and a circulating vortex component 9 is arranged between the seed soaking bin 1 and the screening component 8.

[0030] With such a design, firstly, by setting a counting component 2 near the feed port and the discharge port, the seed input and output volume can be monitored in real time, and then by comparing the amount of feed and discharge, the residence time of the seeds in the seed soaking chamber 1 can be roughly estimated, and then according to the characteristics of different seeds and the required soaking time, the feed speed can be adjusted to ensure that the seeds have enough time to fully absorb water and reach the appropriate water saturation.

[0031] Secondly, an overflow pipe 4 is concentrically arranged in the vortex outlet pipe 3, and the top of the overflow pipe 4 is higher than the top of the vortex outlet pipe 3 by a certain distance, which is conducive to the formation of a stable vortex in the seed soaking liquid in the seed soaking bin 1, so that it circulates and rotates along a specific path. This vortex motion can allow the seeds to fully roll in the seed soaking liquid, ensure that the seeds are in full contact with the seed soaking liquid, improve the uniformity and efficiency of seed soaking, and promote the penetration of the seed soaking liquid for seeds with hard shells or thick seed coats, which is conducive to the absorption of beneficial ingredients; in addition, the filter screen 5 at the top of the overflow pipe 4 can prevent seeds from overflowing, ensure that the seeds are soaked in the seed soaking bin 1, and avoid seed loss and blockage of the circulation system.

[0032] Again, the circulating vortex component 9 can generate a stable vortex, causing the seeds to continuously roll and stir in the soaking solution, so that the contact degree between the seeds and the soaking solution can be controlled by adjusting the intensity of the vortex, thereby affecting the water saturation of the seeds.

[0033] Finally, the screening component 8 screens the soaked seeds and can filter out impurities in the soaking solution to prevent the accumulation of impurities and affect the water quality.

[0034] The screening assembly 8 comprises a screening box 81. The screening box 81 is a hollow structure with an open top, and the top of the screening box 81 is arranged to be inclined downward.

[0035] A seed screen grille 82 is obliquely disposed in the screening box 81 , and the inclination direction of the seed screen grille 82 is the same as the inclination direction of the top of the screening box 81 .

[0036] The screening box 81 is provided with a seed discharging opening near the inclined bottom end of the seed screening grid 82 , and a seed collecting box 83 is provided on the outer wall of the screening box 81 near the bottom of the seed discharging opening.

[0037] With this design, firstly, the top of the screening box 81 is open and tilted downward, which is conducive to the smooth inflow of seeds and soaking water, reduces the resistance and splashing of the feed, and ensures that the material can quickly and stably enter the screening box 81 for processing.

[0038] Secondly, the seed screening grid 82 and the top of the screening box 81 have the same inclination direction, so that the soaked seeds can naturally slide down along the seed screening grid 82 under the action of gravity, thereby improving the smoothness of the discharge; at the same time, the setting of the seed discharge port and the seed collection box 83 facilitates the collection of the screened seeds and facilitates the seeds to enter the next production process.

[0039] The seed screening grid 82 is composed of a plurality of parallel and equidistant steel pipes fixed on the screening box 81, and the spacing between adjacent steel pipes is 0.6 to 0.8 times the minimum diameter of the soaked seeds.

[0040] With this design, the seed screening grid 82 is composed of multiple parallel and equidistant steel pipes, and the spacing between adjacent steel pipes is 0.6-0.8 times the minimum diameter of the soaked seeds, so that seeds that meet the size requirements can be accurately screened out, impurities and unqualified seeds can be removed, and the purity and quality of the seeds can be improved.

[0041] A filter grille 84 is provided below the seed screen grille 82 in the screening box 81 . The inclination direction of the filter grille 84 is opposite to the inclination direction of the top of the screening box 81 . A debris removal port 85 is provided on the outer wall of the screening box 81 near the inclination bottom of the filter grille 84 .

[0042] With this design, the inclination direction of the filter grille 84 is opposite to the top of the screening box 81, which effectively filters out unqualified soaked seeds and impurities in the soaking water, and makes the impurities and seeds move in different directions to avoid re-mixing, thereby improving the removal effect; at the same time, a de-impurity port 85 is opened on the outside of the screening box 81 to facilitate the discharge of impurities, avoid accumulation, and facilitate centralized processing.

[0043] The filter grid 84 is composed of a plurality of parallel and equidistant steel pipes fixed on the screening box 81 , and the gap width of the filter grid 84 is smaller than the gap width of the screening grid 82 .

[0044] With this design, the gap width of the filter grid 84 is smaller than the gap width of the seed screening grid 82, so that unqualified seeds and impurities soaked in the seed soaking liquid can be filtered out.

[0045] An automatic water supply valve 86 is fixedly connected on the outer wall of the screening box 81 and located below the impurity removal port 85. The automatic water supply valve 86 is connected to an external water supply device.

[0046] With this design, the automatic water replenishment valve 86 and the external water supply device are arranged in cooperation, so as to replenish the water lost during the operation of the equipment and the water absorbed by the seeds when soaking. When the water level in the screening box 81 is lower than the water replenishment height of the automatic water replenishment valve 86, the automatic water replenishment valve 86 automatically opens to replenish water. When the water level in the screening box 81 is higher than the water replenishment height of the automatic water replenishment valve 86, the automatic water replenishment valve 86 stops replenishing water, and then automatically replenishes water according to the water level in the screening box 81 to ensure the stability of the liquid level, which is conducive to stable screening. It can also automatically adjust according to the preset water level range, accurately control the amount of water replenishment, and improve the degree of automation and operating efficiency of the equipment.

[0047] In this embodiment, the technology of the automatic water replenishment valve 86 is existing technology and will not be described in detail here.

[0048] The bottom of the screening box 81 is fixedly connected with a return pipe 87 , and the other end of the return pipe 87 is connected with the circulating vortex component 9 .

[0049] With this design, the return pipe 87 connects the bottom of the screening box 81 with the circulating vortex component 9, so that the screened water can return to the seed soaking bin 1, thereby reducing the demand for fresh water resources, realizing the recycling of water, saving water resources and reducing production costs.

[0050] The bottom of the screening box 81 is fixedly connected with a sewage pipe 88 , and a sealing cover 89 is threadedly connected to the sewage pipe 88 .

[0051] With this design, the drain pipe 88 is convenient for bottom drainage during maintenance and decommissioning. Timely discharge of impurities can avoid accumulation of impurities at the bottom of the screening box 81, thereby reducing the risk of clogging the pipe and the grille, thereby helping to maintain smooth water flow and ensure the normal operation of the equipment.

[0052] The circulating vortex component 9 includes a circulating water pump 91, the water inlet end of the circulating water pump 91 is fixedly connected to the return pipe 87, the water outlet end of the circulating water pump 91 is fixedly connected to a water pipe 92, and the other end of the water pipe 92 passes through the outer wall of the seed soaking bin 1 and is connected to the seed soaking bin 1.

[0053] With this design, first, the circulating water pump 91 draws water from the bottom of the screening box 81 through the return pipe 87 through forced circulation and sends it to the seed soaking bin 1 through the water supply pipe 92, ensuring that water flows quickly in the system and improves the circulation efficiency. At the same time, the flow rate and pressure can be adjusted as needed to provide a stable water supply to the seed soaking bin 1, ensuring that the seed soaking process proceeds smoothly.

[0054] Secondly, the high-flow rate water flow output by the circulating water pump 91 can enhance the vortex strength and stability after entering the seed soaking bin 1, so that the seeds can be better tumbled and stirred and fully contact with the soaking liquid, thereby improving the soaking effect. It can also make the water more evenly distributed in the seed soaking bin 1, avoiding local water flow blockage, ensuring that each seed enjoys the same soaking conditions, and improving consistency.

[0055] In this embodiment, the technology of the circulating water pump 91 is the existing technology and will not be described in detail here.

[0056] The water inlet 93 is formed at the connection point between the water delivery pipe 92 and the seed soaking bin 1 , the center line of the water inlet 93 is tangent to the inner wall of the seed soaking bin 1 , and the water inlet 93 is higher than the top of the overflow pipe 4 by a certain distance.

[0057] With this design, firstly, water entering in the tangential direction can naturally form a vortex, causing the seeds to roll and stir so as to fully contact with the soaking liquid, thereby improving the soaking effect. The height difference of the water inlet 93 further enhances the stability of the vortex, making it less susceptible to external interference.

[0058] Secondly, the eddy current makes the seeds evenly distributed, avoiding accumulation and uneven local soaking, ensuring the consistency and effect of soaking. At the same time, tangential water inlet and eddy current speed up the material exchange rate between seeds and soaking liquid, improves the soaking efficiency, and accelerates the seeds to absorb water and soak.

[0059] Finally, the water inlet 93 is higher than the top of the overflow pipe 4, which helps to stabilize the water level in the seed soaking bin 1. Excess water can flow out through the overflow pipe 4 to maintain a stable water level range, and will not cause major interference to the water inlet during overflow, ensuring that the water inlet is stable and continuous, allowing the seed soaking process to continue.

[0060] The counting assembly 2 includes a feed counting grating 21 disposed near the feed port and a discharge counting grating 22 disposed near the discharge port.

[0061] The feed counting grating 21 is composed of multiple groups of parallel infrared beam emitters and corresponding multiple groups of infrared beam receivers to form an equidistant infrared beam grid located at the feed port, and the gap of the feed counting grating 21 is about 0.5 times the minimum diameter of unsoaked seeds.

[0062] The discharge counting grating 22 is composed of multiple groups of parallel infrared beam emitters and corresponding multiple groups of infrared beam receivers to form an equidistant infrared beam grid located at the feed inlet, and the gap of the discharge counting grating 22 is about 0.5 times the minimum diameter of the soaked seeds.

[0063] When the feed counting grating 21 and the discharge counting grating 22 are working, when the seeds enter and exit the seed soaking chamber 1, 2-3 infrared light beams will be blocked at the same time, and a discontinuous reception signal will appear at the infrared receiver. According to the statistics of the number of discontinuous reception signals, the approximate values ​​of the feed and discharge seeds can be obtained, and the feed amount can be controlled by the discharge seed value to make the feed and discharge balanced.

[0064] In this embodiment, the technology of the feed counting grating 21 and the discharge counting grating 22 is the existing technology and will not be described in detail here.

[0065] The bottom of the overflow pipe 4 is flush with the bottom of the discharge port.

[0066] With this design, the bottom of the overflow pipe 4 is flush with the bottom of the discharge port, so that the soaked seeds can flow out of the soaking bin 1 more smoothly. At the same time, since the two are at the same height, the seeds can pass through the discharge port more efficiently under the action of gravity and the promotion of eddy currents, reducing blockage and retention during the discharge process and improving the discharge efficiency.

[0067] The top of the spoiler 6 is lower than the top of the overflow pipe 4 and higher than the top of the vortex outlet pipe 3 , and the bottom of the spoiler 6 is lower than the top of the vortex outlet pipe 3 .

[0068] With such a design, firstly, the top of the spoiler 6 is lower than the top of the overflow pipe 4 and higher than the top of the vortex outlet pipe 3, and its bottom is lower than the top of the vortex outlet pipe 3. This position setting enables the spoiler 6 to effectively guide the water flow to form a vortex when the water flows through the vortex outlet pipe 3. The water flow changes its flow direction under the action of the spoiler 6, which increases the rotation speed and intensity of the water flow, thereby enhancing the vortex effect in the seed soaking bin 1.

[0069] Secondly, since the baffle surface of the spoiler 6 is inclined along the tangent direction of the eddy current in the seed soaking bin 1 and toward the central axis direction of the seed soaking bin 1, it can play a certain restraining role on the eddy current, preventing the diffusion and weakening of the eddy current, so that the seeds are always in a strong eddy current environment in the seed soaking bin 1, fully tumbling and stirring, and fully contacting with the soaking liquid, thereby improving the soaking effect.

[0070] Thirdly, it can promote the circulation of soaking liquid, avoid local poor water flow and dead water areas, let the seeds enjoy the same soaking conditions, improve consistency, and make the water flow more evenly distributed, avoiding seed accumulation and local uneven soaking.

[0071] The top of the seed soaking bin 1 is a tank body with a circular cross-section, and the bottom of the seed soaking bin 1 is a conical bottom.

[0072] With this design, firstly, the round tank body makes the feeding uniform and avoids congestion and accumulation, and the conical bottom makes the discharging efficient and reduces residue.

[0073] Secondly, the round tank body is conducive to the formation of uniform vortex, which promotes full contact between seeds and soaking liquid. The conical bottom combined with the round tank body can enhance the vortex and accelerate the soaking of seeds.

[0074] Thirdly, the circle disperses pressure and the cone concentrates gravity, and can also achieve a larger volume in a limited space, thereby improving space utilization.

[0075] Finally, during cleaning and maintenance, the no-dead-angle design makes cleaning easy, reduces the risk of bacterial growth and cross-contamination, and also facilitates operators to perform inspection and maintenance work.

[0076] The vortex water outlet pipe 3 and the overflow pipe 4 are fixedly connected together by at least two connecting plates 14 .

[0077] This design, firstly, increases the number of connection points to make the connection more stable, which can disperse the external forces on the pipeline during fluid flow, such as water flow impact and vibration, and improve the stability of the system; secondly, multiple connecting plates 14 can make the force more evenly distributed, avoid single-point concentrated stress causing damage to the connection part, reduce the stress level of the connection point, and extend the service life of the pipeline.

[0078] A low-level drainage pipe 10 is fixedly connected to the bottom side wall of the seed soaking bin 1 , and a blocking cover 11 is threadedly connected to the other end of the low-level drainage pipe 10 .

[0079] With this design, when cleaning or replacing the soaking liquid, the water in the soaking bin 1 is completely drained to ensure that the interior is thoroughly cleaned. After draining, it is convenient for operators to clean impurities in the bin and clean the bin wall. Without the low-level drain pipe 10, cleaning is difficult and costly.

[0080] The first supporting legs 12 are fixedly connected to the four corners of the bottom of the seed soaking bin 1, and the second supporting legs 13 are fixedly connected to the four corners of the bottom of the screening box 81.

[0081] This design ensures that the seed soaking bin 1 and the screening box 81 are subjected to uniform force in all directions, and disperses their own weight and the force acting during operation to the ground, thereby ensuring stability and preventing tilting. Even if subjected to uneven external force, the force distribution can be adjusted to maintain balance, thereby avoiding damage and safety accidents.

[0082] The present invention also discloses a method for using the continuous eddy current seed soaking device. Based on the above-mentioned continuous eddy current seed soaking device, the method comprises the following steps: S1. Equipment installation and commissioning: Ensure that the automatic water supply valve 86, circulating water pump 91, feed counting grating 21, discharge counting grating 22 and other components operate normally.

[0083] S2, water replenishment and start-up circulation: the automatic water replenishment valve 86 replenishes water to the screening box 81 to the control liquid level, and at the same time starts the circulating water pump 91 to send the water in the screening box 81 into the seed soaking bin 1 through the circulating vortex component 9.

[0084] S3, liquid level control: when the water level in the seed soaking bin 1 reaches the top water outlet position of the vortex outlet pipe 3, part of the water flows into the screening box 81 from the bottom through the gap between the vortex outlet pipe 3 and the overflow pipe 4; at this time, if the water output of the vortex outlet pipe 3 is less than the water input of the water inlet 93 in the seed soaking bin 1, the liquid level in the seed soaking bin 1 continues to rise, and finally reaches the top position of the overflow pipe 4 and overflows out of the seed soaking bin 1 through the top mesh port of the overflow pipe 4, so that the liquid level height in the seed soaking bin 1 remains relatively stable near the upper diameter position of the overflow pipe 4, so that the liquid level in the screening box 81 finally stabilizes near the liquid level controlled by the automatic water replenishment valve 86.

[0085] S4. Vortex formation and control: The circulating water pump 91 runs continuously, and water enters the seed soaking bin 1 from the water inlet 93 of the seed soaking bin 1 along a circular direction tangential to the inner side of the seed soaking bin 1, so that a continuous vortex is formed in the seed soaking bin 1, and the vortex angular velocity is proportional to the water inlet flow rate and flow velocity, and indirectly proportional to the water volume and lift of the circulating water pump 91. The vortex angular velocity in the seed soaking bin 1 can be indirectly controlled by adjusting the operating frequency of the water pump motor.

[0086] S5. Increase the oxygen content of the vortex: the water flowing out from the water inlet 93 first contacts the inner wall of the seed soaking bin 1 and the air in the seed soaking bin 1, and then reaches the upper liquid surface in the seed soaking bin 1 with a relatively high water flow, and impacts the vortex near the liquid surface and drives the vortex to continue to operate. The two water flows with different flow rates at the liquid surface position impact the basic interface position to produce a Venturi effect. The water flow with a higher flow rate flowing out from the water outlet will form a low-pressure area at the contact surface with the vortex and drive air into the vortex to generate a large number of bubbles. The bubbles in the vortex are affected by the water pressure and part of the oxygen in the bubbles is integrated into the vortex to increase the oxygen content of the vortex, thereby inhibiting the growth of anaerobic bacteria during the seed soaking process and preventing the water quality from becoming acidic and deteriorating.

[0087] S6, seed soaking process: the unsoaked seeds enter the soaking bin 1 from the feed port on the top of the soaking bin 1 through an external electric feeding device, the feed counting grating 21 measures and controls the number of fed seeds to match the carrying capacity of the soaking bin 1, the seeds are blocked by the feed guide plate 7 in the soaking bin 1, and fall into the water from the inner edge of the soaking bin 1 along the outer conical surface of the feed guide plate 7 for soaking, and the seeds that are not soaked thoroughly are at the bottom of the soaking bin 1 and near the soaking bin 1 due to the density greater than the density of water. The position of the inner wall follows the vortex movement, and the seeds move faster in the water to complete the soaking process. After the water absorption and soaking are completed, the seeds produce an oxidation reaction when germinating, and the density gradually decreases to approach the density of water. In the vortex in the seed soaking bin 1, the seeds gradually move away from the bottom of the seed soaking bin 1 and the inner wall of the seed soaking bin 1. When the seeds move to the position of the spoiler 6 with the vortex, they are blocked or collided by the spoiler 6, and move toward the position of the vortex outlet pipe 3 along the inclined direction of the spoiler 6, flow out of the vortex outlet pipe 3 and fall into the screening box 81.

[0088] S7. Discharge feedback: the discharge counting grating 22 senses and measures the number of seeds flowing out of the vortex outlet pipe 3, and feeds it back to the feeding system. The feeding system replenishes the corresponding number of seeds into the seed soaking bin 1. At the same time, the feeding counting grating 21 senses and measures the number of seeds added to the seed soaking bin 1, thereby ensuring that the number of seeds in the seed soaking bin 1 continues to match the carrying capacity of the seed soaking bin 1.

[0089] S8, screening and water circulation: the soaked seeds falling into the screening box 81 are blocked by the seed screening grid 82 and slide down along the inclined direction of the seed screening grid 82 to fall into the seed outlet and enter the seed collecting box 83. The water flowing out from the vortex outlet pipe 3 and the overflow pipe 4 is screened by the seed screening grid 82 to remove seeds, and then screened by the filter grid 84 to remove impurities and then falls into the bottom of the screening box 81. Then the water enters the circulating water pump 91 through the return pipe 87. The circulating water pump 91 is pressurized and sent to the seed soaking bin 1 through the delivery pipe for recycling.
