Description

Technical Field

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

[0002] In fields such as seed sowing and sprout production, it is often necessary to pre-soak the seeds of fruits and vegetables before sowing to promote rapid germination of the seeds. Especially in the field of sprout production, it is necessary to soak the vast majority of seeds to ensure the germination rate and germination rate.

[0003] The existing seed soaking processes are mostly completed manually. The seeds are directly immersed in the corresponding water and then fished out. The operation is relatively inconvenient, which will result in low work efficiency of seed soaking and is not conducive to agricultural work. Therefore, an automatic seed soaking equipment is needed.

[0004] For example, a Chinese patent with the patent publication number CN221081955U discloses a full-automatic seed soaking equipment, including a base. On the upper end surface of the base, two symmetrically arranged support seats are fixedly connected. On the side walls of the two support seats close to each other, support shafts are rotatably connected. The two support shafts are jointly fixedly connected with a working cylinder. A working component is arranged in the working cylinder. A turnover motor is arranged on one of the support seats, and the output end of the turnover motor is fixedly connected to one of the support shafts. An opening is arranged on the 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 arranged on the outer wall of the working cylinder away from the two support shafts. A working shaft is arranged on the working motor, and the working shaft penetrates through the working cylinder. A stirring component is fixedly connected to the working shaft.

[0005] Although the above equipment realizes automatic completion of work such as seed soaking and picking, greatly reducing the manual labor, there are still many deficiencies in the above equipment:

[0006] Firstly, the above equipment lacks accurate monitoring and adjustment means for the water saturation degree of the seeds, and it is easy to have the situation of insufficient or excessive seed soaking.

[0007] Secondly, the equipment cannot maintain the water quality, so the water needs to be replaced repeatedly during the seed germination process, which increases the manual labor and causes an increase in labor costs.

[0008] Thirdly, the water is easy to get sticky after standing for a long time. When this sticky water is used for seed cultivation, it will have an adverse effect on the seeds, especially it is easy to damage the embryo of the seeds. Once the seed embryo is damaged, the germination rate of the seeds will decrease, seriously affecting the normal germination and subsequent growth and development of the seeds. Summary of the Invention

[0009] The main technical problem to be solved by the present invention is to provide a continuous automatic seed soaking device and method, which can accurately control the water saturation of seeds, ensure the best seed soaking state, maintain stable water quality to provide a healthy environment for seeds, reduce the risk of damage, and improve the germination rate and seedling health.

[0010] To solve the above technical problems, the present invention provides the following technical solutions:

[0011] A continuous eddy current seed soaking device includes a seed soaking bin. The top and bottom of the seed soaking bin are respectively provided with a feed inlet and a discharge outlet. Counting components are arranged at positions on the outer side wall of the seed soaking bin close to the feed inlet and the discharge outlet. A vortex drain pipe is arranged at a position on the inner bottom wall of the seed soaking bin close to the discharge outlet. An overflow pipe is concentrically and fixedly arranged inside the vortex drain pipe, and the top of the overflow pipe is higher than the top of the vortex drain pipe by a certain distance. A filter screen for preventing seeds from overflowing is arranged at the top end of the overflow pipe. A plurality of spoiler plates are arranged in a circumferential symmetry on the outer side of the vortex drain pipe, and the flow blocking surface of the spoiler plate is inclined along the tangent direction of the eddy current in the seed soaking bin and towards the central axis of the seed soaking bin. A conical feed guiding plate is arranged directly below the feed inlet in the seed soaking bin, and the feed guiding plate is located directly above the vortex drain pipe. The maximum diameter of the feed guiding plate is larger than the diameter of the vortex drain pipe. A screening component for separately separating the soaked seeds and impurities is arranged below the seed soaking bin. A circulating eddy current component is arranged between the seed soaking bin and the screening component.

[0012] The following is a further optimization of the above technical solutions by the present invention:

[0013] The screening component includes a screening box. The screening box is a hollow structure with an open top. The top of the screening box is inclined downward. A seed screening grid is inclined in the screening box, and the inclination direction of the seed screening grid is the same as the inclination direction of the top of the screening box. A seed discharge port is arranged at a position on the screening box close to the lower inclined end of the seed screening grid. A seed collecting box is arranged on the outer side wall of the screening box close to the position below the seed discharge port.

[0014] Further optimization: A filtering grid is inclined below the seed screening grid in the screening box, and the inclination direction of the filtering grid is opposite to the inclination direction of the top of the screening box. An impurity removal port is arranged at a position on the outer side wall of the screening box close to the lower inclined end of the filtering grid.

[0015] Further optimization: An automatic water replenishing valve is fixedly communicated with the outer side wall of the screening box below the impurity removal port. The automatic water replenishing valve is connected to an external water supply device.

[0016] Further optimization: A return pipe is fixedly communicated with the bottom of the screening box. The other end of the return pipe is connected to the circulating eddy current component.

[0017] Further optimization: The circulating eddy current assembly includes a circulating water pump. The water inlet end of the circulating water pump is fixedly communicated with the return water pipe, and the water outlet end of the circulating water pump is communicated with a water delivery pipe. The other end of the water delivery pipe penetrates through the outer wall of the seed soaking bin and is communicated with the seed soaking bin.

[0018] Further optimization: The water delivery pipe forms a water inlet when communicating with 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.

[0019] Further optimization: The counting assembly includes a feeding counting grating arranged near the feeding port and a discharging counting grating arranged near the discharging port; The feeding counting grating is formed by a plurality of groups of juxtaposed infrared beam emitters and corresponding infrared beam receivers to form an equidistant infrared beam grid at the feeding port position, and the gap of the feeding counting grating is about 0.5 times the minimum diameter of the unsoaked seeds; The discharging counting grating is formed by a plurality of groups of juxtaposed infrared beam emitters and corresponding infrared beam receivers to form an equidistant infrared beam grid at the discharging port position, and the gap of the discharging counting grating is about 0.5 times the minimum diameter of the soaked seeds.

[0020] Further optimization: The top of the spoiler is lower than the top of the overflow pipe and higher than the top of the eddy current outlet pipe, and the bottom of the spoiler is lower than the top of the eddy current outlet pipe.

[0021] The present invention also provides a method for using a continuous eddy current seed soaking device. Based on the above continuous eddy current seed soaking device, the following steps are carried out:

[0022] S1. Equipment installation and debugging: Ensure that components such as the automatic water replenishing valve, circulating water pump, feeding counting grating, and discharging counting grating work properly;

[0023] S2. Water replenishment and start of circulation: The automatic water replenishing valve replenishes water to the screening box to the controlled liquid level, and at the same time, the circulating water pump is started to send the water in the screening box into the seed soaking bin;

[0024] S3. Liquid level control: When the water level in the seed soaking bin reaches the position of the water outlet of the top of the eddy current 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 levels of the seed soaking bin and the screening box are stable;

[0025] S4. Formation of eddy current and control: The circulating water pump operates to make water enter the seed soaking bin in a specific direction to form an eddy current, and the angular velocity of the eddy current can be controlled by adjusting the frequency of the water pump motor;

[0026] S5. Increase the oxygen content of the eddy current: The water flowing out of the water inlet generates a Venturi effect in the seed soaking bin, driving air to enter the eddy current to generate bubbles, increasing the oxygen content of the eddy current to inhibit the growth of anaerobic bacteria and prevent the water quality from becoming acidic and deteriorating;

[0027] S6. Seed soaking process: The unsoaked seeds enter from the feed inlet, fall into the water through the feed guide plate for soaking. The unthoroughly soaked seeds move with the eddy current at the bottom and side walls of the soaking bin. After soaking, their positions change due to density changes and they move to the spoiler plate, where they are guided into the vortex outlet pipe and fall into the screening box.

[0028] S7. Discharge feedback: The discharge counting grating measures the number of seeds flowing out and feeds back to the feeding system to supplement seeds. At the same time, the feeding counting grating measures the number of seeds entering to ensure that the number of seeds in the soaking bin is continuously matched with the carrying capacity of the soaking bin.

[0029] S8. Screening and water circulation: The soaked seeds are blocked by the grille in the screening box and slide down to enter the next process. The water flowing out is filtered by the filter grille to remove seeds and impurities and then returns to the bottom of the screening box, and is then pressurized by the circulation water pump and sent back to the soaking bin for recycling.

[0030] The present invention adopts the above technical solutions and has the following beneficial effects:

[0031] 1. By setting counting components near the feed inlet and the discharge outlet, the present invention can monitor the inflow and outflow of seeds in real time. Furthermore, by comparing the number of seeds fed and discharged, the residence time of seeds in the soaking bin can be roughly estimated. Then, according to the characteristics of different seeds and the required soaking time, the feeding speed can be adjusted to ensure that the seeds have enough time to fully absorb water and reach the appropriate water saturation level.

[0032] 2. By concentrically arranging an overflow pipe inside the vortex outlet pipe in the present invention, and the top of the overflow pipe is higher than the top of the vortex outlet pipe by a certain distance, it is beneficial to form a stable eddy current of the soaking liquid in the soaking bin, making it circulate and rotate along a specific path. This eddy current movement can make the seeds fully tumble in the soaking liquid, ensuring full contact between the seeds and the soaking liquid, improving the uniformity and efficiency of soaking. For seeds with hard shells or thick seed coats, it can promote the penetration of the soaking liquid and facilitate the absorption of beneficial components. In addition, the filter screen at the top of the overflow pipe can prevent seeds from overflowing, ensuring that the seeds complete soaking in the soaking bin and avoiding seed loss and blockage of the circulation system.

[0033] 3. The present invention can generate a stable eddy current through the circulating eddy current component, making the seeds constantly tumble and stir in the soaking liquid. Thus, by adjusting the intensity of the eddy current, the contact degree between the seeds and the soaking liquid can be controlled, and further the water saturation level of the seeds can be affected.

[0034] 4. The present invention screens the soaked seeds through the screening component and can filter impurities in the soaking liquid to prevent the accumulation of impurities from affecting the water quality.

[0035] 5. By adopting the above technical solution, the present invention can accurately control the water saturation of seeds, ensure the best seed soaking state, maintain stable water quality to provide a healthy environment for seeds, reduce the risk of damage, and improve the germination rate and the health of seedlings.

Detailed implementation manners

[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0049] As Figures 1-9 shown, a continuous eddy - current seed soaking device includes a seed soaking bin 1. Feed ports and discharge ports are respectively arranged at the top and bottom of the seed soaking bin 1. Counting components 2 are arranged at positions on the outer side wall of the seed soaking bin 1 near the feed port and the discharge port. A vortex water outlet pipe 3 is arranged at a position on the inner bottom wall of the seed soaking bin 1 near the discharge port. An overflow pipe 4 is concentrically and fixedly arranged inside the vortex water outlet pipe 3, and the top of the overflow pipe 4 is higher than the top of the vortex water outlet pipe 3 by a certain distance. A filter screen 5 for preventing seeds from overflowing is arranged at the top end of the overflow pipe 4. A plurality of spoilers 6 are arranged in a circumferential symmetry on the outer side of the vortex water outlet pipe 3, and the flow - blocking surface of the spoiler 6 is inclined along the tangent direction of the eddy current in the seed soaking bin 1 and towards the central axis direction of the seed soaking bin 1. A conical feeding guide plate 7 is arranged directly below the feed port in the seed soaking bin 1, and the feeding guide plate 7 is located directly above the vortex water outlet pipe 3. The maximum diameter of the feeding guide plate 7 is larger than the diameter of the vortex water outlet pipe 3. A screening component 8 for separating the soaked seeds and impurities respectively is arranged below the seed soaking bin 1. A circulating eddy current component 9 is arranged between the seed soaking bin 1 and the screening component 8.

[0050] With such a design, first, by arranging the counting components 2 near the feed port and the discharge port, the inflow and outflow amounts of seeds can be monitored in real time. Furthermore, by comparing the number of seeds fed and discharged, the residence time of the seeds in the seed soaking bin 1 can be roughly estimated. Then, according to the characteristics of different seeds and the required seed soaking time, the feeding speed can be adjusted to ensure that the seeds have enough time to fully absorb water and reach an appropriate water - soaking saturation degree.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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 .

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] With such a design, the seed screening grid 82 is composed of multiple parallel steel pipes with equal spacing, and the spacing between adjacent steel pipes is 0.6 - 0.8 times the minimum diameter of the soaked seeds, so as to accurately screen out the seeds that meet the size requirements, remove impurities and unqualified seeds, and thus improve the purity and quality of the seeds.

[0061] A filter grid 84 is arranged below the seed screening grid 82 in the screening box 81. The inclination direction of the filter grid 84 is opposite to the inclination direction of the top of the screening box 81. An impurity removal port 85 is arranged on the outer side wall of the screening box 81 near the inclined bottom end of the filter grid 84.

[0062] With such a design, the inclination direction of the filter grid 84 is opposite to the top of the screening box 81, effectively filtering out the unqualified soaked seeds and impurities in the soaking water, and making the impurities and seeds move in different directions to avoid re - mixing and improve the removal effect; at the same time, an impurity removal port 85 is opened on the outer side of the screening box 81, which is convenient for discharging impurities, avoiding accumulation and facilitating centralized treatment.

[0063] The filter grid 84 is fixed on the screening box 81 by multiple parallel steel pipes with equal spacing, and the gap width of the filter grid 84 is smaller than the gap width of the seed screening grid 82.

[0064] With such a design, the gap width of the filter grid 84 is smaller than the gap width of the seed screening grid 82, and it can filter out the unqualified seeds and impurities in the soaking liquid.

[0065] An automatic water replenishing valve 86 is fixedly connected and communicated on the outer side wall of the screening box 81 and below the impurity removal port 85. The automatic water replenishing valve 86 is connected and communicated with an external water supply device.

[0066] With such a design, the automatic water replenishing valve 86 and the external water supply device are cooperatively arranged, so as to supplement the water lost during the operation of the equipment and the water absorbed by the seeds during soaking. When the water level in the screening box 81 is lower than the water replenishing height of the automatic water replenishing valve 86, the automatic water replenishing valve 86 automatically opens for water replenishment. When the water level in the screening box 81 is higher than the water replenishing height of the automatic water replenishing valve 86, the automatic water replenishing valve 86 stops water replenishment. Thus, water is automatically replenished according to the water level in the screening box 81 to ensure the stability of the liquid level and facilitate the stable progress of screening; it can also be automatically adjusted according to the preset water level range to accurately control the water replenishment volume, improve the automation degree and operation efficiency of the equipment.

[0067] In this embodiment, the technology for the automatic water replenishing valve 86 to work is prior art and will not be elaborated here.

[0068] A return pipe 87 is fixedly connected and communicated at the bottom of the screening box 81. The other end of the return pipe 87 is connected and communicated with the circulating eddy current assembly 9.

[0069] With such a design, the return pipe 87 connects the bottom of the screening box 81 to the circulating eddy current assembly 9, enabling the water after screening to return to the seed soaking bin 1, thus reducing the demand for fresh water resources, achieving the recycling of water, saving water resources, and reducing production costs.

[0070] A sewage discharge pipe 88 is fixedly connected to the bottom of the screening box 81, and a sealing cover 89 is threadedly connected to the sewage discharge pipe 88.

[0071] With such a design, the sewage discharge pipe 88 is convenient for draining water and discharging sewage at the bottom during maintenance and shutdown. Timely discharging of impurities can prevent impurities from accumulating at the bottom of the screening box 81, thereby reducing the risk of blocking pipelines and grilles, and helping to maintain smooth water flow and ensure the normal operation of the equipment.

[0072] The circulating eddy current assembly 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, and the water outlet end of the circulating water pump 91 is fixedly connected to a water delivery pipe 92. The other end of the water delivery pipe 92 penetrates the outer wall of the seed soaking bin 1 and is connected to the seed soaking bin 1.

[0073] With such a design, first of all, through forced circulation, the circulating water pump 91 sucks water from the bottom of the screening box 81 through the return pipe 87 and sends it to the seed soaking bin 1 through the water delivery pipe 92, ensuring the rapid flow of water in the system, improving the circulation efficiency, and being able to adjust the flow rate and pressure as needed to stably supply water to the seed soaking bin 1 and ensure the smooth progress of the seed soaking process.

[0074] Secondly, after the high-velocity water flow output by the circulating water pump 91 enters the seed soaking bin 1, it can enhance the eddy current intensity and stability, enabling the seeds to roll and stir better and come into full contact with the seed soaking liquid, improving the seed soaking effect. It can also make the water more evenly distributed in the seed soaking bin 1, avoiding poor water flow in local areas, ensuring that each seed enjoys the same seed soaking conditions, and improving consistency.

[0075] In this embodiment, the technology for the circulating water pump 91 to work is prior art and will not be elaborated here.

[0076] A water inlet 93 is formed at the connection 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 at a certain distance above the top of the overflow pipe 4.

[0077] With such a design, first of all, the water inlet in the tangential direction can naturally form an eddy current, enabling the seeds to roll and stir and come into full contact with the seed soaking liquid, improving the seed soaking effect. The height difference of the water inlet 93 further enhances the stability of the eddy current and makes it less susceptible to external interference.

[0078] Secondly, the eddy current evenly distributes the seeds, avoiding accumulation and uneven local seed soaking, ensuring the consistency and effectiveness of seed soaking. At the same time, the tangential water inlet and the eddy current accelerate the mass exchange rate between the seeds and the soaking liquid, improve the seed soaking efficiency, and accelerate the water absorption and soaking of the seeds.

[0079] Finally, the water inlet 93 being higher than the top of the overflow pipe 4 helps to stabilize the water level in the seed soaking bin 1. The excess water can flow out through the overflow pipe 4 to maintain the water level within a stable range, and there will be no major interference to the water inlet during overflow, ensuring stable and continuous water inlet and enabling the seed soaking process to proceed continuously.

[0080] The counting component 2 includes a feeding counting grating 21 arranged near the feeding port and a discharging counting grating 22 arranged near the discharging port.

[0081] The feeding counting grating 21 is formed by a plurality of groups of juxtaposed infrared beam emitters and corresponding infrared beam receivers to form an equidistant infrared beam grid at the position of the feeding port. The gap of the feeding counting grating 21 is about 0.5 times the minimum diameter of the unsoaked seeds.

[0082] The discharging counting grating 22 is formed by a plurality of groups of juxtaposed infrared beam emitters and corresponding infrared beam receivers to form an equidistant infrared beam grid at the position of the feeding port. The gap of the discharging counting grating 22 is about 0.5 times the minimum diameter of the soaked seeds.

[0083] When the feeding counting grating 21 and the discharging counting grating 22 are working, when the seeds enter and exit the seed soaking bin 1, they will block 2 - 3 infrared beams at the same time, and then a discontinuous reception signal will appear at the infrared receiver. The approximate values of the feeding and discharging seeds can be obtained according to the statistics of the discontinuous reception signal quantity, and the feeding amount can be controlled by the discharging seed value to make the feeding and discharging evenly matched.

[0084] In this embodiment, the technology of the feeding counting grating 21 and the discharging counting grating 22 working is prior art and will not be elaborated in detail here.

[0085] The bottom of the overflow pipe 4 is flush with the bottom of the discharging port.

[0086] With such a design, the bottom of the overflow pipe 4 being flush with the bottom of the discharging port makes the soaked seeds flow out of the seed soaking bin 1 more smoothly. At the same time, since they are at the same height, the seeds can pass through the discharging port more efficiently under the action of gravity and the eddy current, reducing the blockage and retention during the discharging process and improving the discharging efficiency.

[0087] The top of the spoiler 6 is lower than the top of the overflow pipe 4 and higher than the top of the eddy current outlet pipe 3, and the bottom of the spoiler 6 is lower than the top of the eddy current outlet pipe 3.

[0088] With such a design, first of all, 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 water pipe 3, and its bottom is lower than the top of the vortex outlet water pipe 3. This position setting enables the spoiler 6 to effectively guide the water flow to form a vortex when the water flow passes through the vortex outlet water pipe 3. Under the action of the spoiler 6, the water flow changes its direction, increasing the rotation speed and intensity of the water flow, thereby enhancing the vortex effect in the seed soaking bin 1.

[0089] Secondly, since the flow blocking surface of the spoiler 6 is inclined along the tangent direction of the vortex in the seed soaking bin 1 and towards the central axis of the seed soaking bin 1, it can play a certain role in restraining the vortex, preventing the diffusion and weakening of the vortex, so that the seeds are always in a strong vortex environment in the seed soaking bin 1, fully tumbling and stirring, and making full contact with the seed soaking liquid, thus improving the seed soaking effect.

[0090] Thirdly, it can promote the circulation of the seed soaking liquid, avoid local water flow blockage and dead water areas, enable the seeds to enjoy the same seed soaking conditions, improve consistency, and also make the water flow more evenly distributed, avoiding seed accumulation and uneven local seed soaking.

[0091] The upper part of the seed soaking bin 1 is a tank body with a circular cross-section, and the lower part of the seed soaking bin 1 is a conical bottom.

[0092] With such a design, first of all, the circular tank body makes the feeding uniform, avoiding congestion and accumulation, and the conical bottom enables efficient discharging and reduces residue.

[0093] Secondly, the circular tank body is conducive to forming a uniform vortex, promoting the full contact between the seeds and the seed soaking liquid, and the conical bottom combined with the circular tank body can enhance the vortex and accelerate the seed soaking.

[0094] Thirdly, the circle disperses pressure, the cone concentrates gravity, and it can also achieve a larger volume in a limited space, improving the space utilization rate.

[0095] Finally, during cleaning and maintenance, the non-dead-angle design is easy to clean, reducing the risk of bacterial growth and cross-contamination, and is also convenient for operators to carry out inspection and maintenance work.

[0096] The vortex outlet water pipe 3 and the overflow pipe 4 are fixedly connected together through at least two connecting plates 14.

[0097] With such a design, first of all, increasing the number of connection points makes the connection more stable, can disperse the external forces received by the pipes during fluid flow, such as water flow impact force and vibration, etc., improving the system stability; secondly, multiple connecting plates 14 can make the force more evenly distributed, avoiding damage to the connection part caused by single-point concentrated stress, reducing the stress level of the connection points, and extending the service life of the pipes.

[0098] A low-level drain pipe 10 is fixedly connected and communicated on the bottom side wall of the seed soaking bin 1, and the other end of the low-level drain pipe 10 is threadedly connected with a plugging cover 11.

[0099] With this design, when cleaning or replacing the seed soaking liquid, the water in the seed soaking bin 1 is completely drained, ensuring thorough internal cleaning. After draining, it is convenient for operators to clean the impurities in the bin and wash the bin wall. Without the low-level drain pipe 10, the cleaning is difficult and costly.

[0100] At the four corners of the bottom of the seed soaking bin 1, first support legs 12 are fixedly connected, and at the four corners of the bottom of the screening box 81, second support legs 13 are fixedly connected.

[0101] With this design, it is ensured that the seed soaking bin 1 and the screening box 81 are uniformly stressed in all directions, dispersing the self-weight of the seed soaking bin 1 and the screening box 81 and the acting force during operation to the ground, ensuring stability, preventing tilting, and even when subjected to uneven external forces, the force distribution can be adjusted to maintain balance, avoiding damage and safety accidents.

[0102] The present invention also discloses a usage method of a continuous eddy current seed soaking device. Based on the above-mentioned continuous eddy current seed soaking device, the usage method includes the following steps:

[0103] S1. Equipment installation and debugging: Ensure that components such as the automatic water replenishing valve 86, the circulation water pump 91, the feeding counting grating 21, and the discharging counting grating 22 work properly.

[0104] S2. Water replenishing and starting the circulation: The automatic water replenishing valve 86 replenishes water to the screening box 81 to the controlled liquid level, and at the same time, the circulation water pump 91 is started to send the water in the screening box 81 into the seed soaking bin 1 through the circulation eddy current assembly 9.

[0105] S3. Liquid level control: When the water level in the seed soaking bin 1 reaches the position of the top water outlet of the eddy current outlet pipe 3, part of the water flows from the bottom into the screening box 81 through the gap between the eddy current outlet pipe 3 and the overflow pipe 4; at this time, if the water output of the eddy current 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 position of the top of the overflow pipe 4 and overflows from the top mesh opening of the overflow pipe 4 out of the seed soaking bin 1, 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, and thus the liquid level in the screening box 81 finally stabilizes near the controlled liquid level of the automatic water replenishing valve 86.

[0106] S4. Forming eddy current and control: The circulation water pump 91 continuously operates, and the water enters the seed soaking bin 1 along the circumferential direction tangent to the inner circumference of the seed soaking bin 1 from the water inlet 93, forming a continuous eddy current in the seed soaking bin 1. And the angular velocity of the eddy current is proportional to the water input flow rate and velocity, and indirectly proportional to the water volume and head of the circulation water pump 91. The angular velocity of the eddy current in the seed soaking bin 1 can be indirectly controlled by adjusting the operating frequency of the water pump motor.

[0107] S5. Increase the oxygen content in the eddy current: The water flowing out from the water inlet 93 first contacts the inner wall of the seed soaking bin 1 and the air inside the seed soaking bin 1, and then reaches the upper liquid level inside the seed soaking bin 1 with a relatively high water flow rate, and impacts the eddy current near the liquid level and promotes the continuous operation of the eddy current. The impact of two water flows with different flow rates at the liquid level position on the basic interface position generates the Venturi effect. The higher flow rate water flowing out from the water outlet will form a low-pressure area at the contact surface with the eddy current and drive air into the eddy current to generate a large number of bubbles. The bubbles in the eddy current will dissolve some oxygen in the bubbles into the eddy current under the influence of water pressure to increase the oxygen content in the eddy current, inhibit the growth of anaerobic bacteria during the seed soaking process, and prevent the water quality from becoming acidic and deteriorating.

[0108] S6. Seed soaking process: The unsoaked seeds enter the seed soaking bin 1 from the feed inlet at the top of the seed soaking bin 1 through an external electric feeding device. The feeding counting grating 21 measures and controls the number of fed seeds to match the carrying capacity of the seed soaking bin 1. The seeds are blocked by the feeding guide plate 7 inside the seed soaking bin 1 and fall into the water along the outer conical surface of the feeding guide plate 7 from the inner edge of the seed soaking bin 1 for soaking. The unthoroughly soaked seeds, due to their density being greater than that of water, move along with the eddy current at the bottom of the seed soaking bin 1 and near the inner side wall of the seed soaking bin 1 under the action of gravity and centrifugal force. The seeds move faster in the water to complete the soaking process. After soaking and absorbing water, when the seeds germinate, an oxidation reaction occurs and the density gradually decreases and approaches the density of water. In the eddy current inside the seed soaking bin 1, the seeds gradually move away from the bottom of the seed soaking bin 1 and the inner side wall of the seed soaking bin 1. When the seeds move to the position of the spoiler 6 along with the eddy current, they are blocked or collided by the spoiler 6 and move along the inclined direction of the spoiler 6 surface towards the eddy current water outlet pipe 3, flow out from the eddy current water outlet pipe 3 and fall into the screening box 81.

[0109] S7. Discharge feedback: The discharge counting grating 22 senses and measures the number of seeds flowing out from the eddy current water outlet pipe 3 and feeds it back to the feeding system. The feeding system supplements 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, so as to ensure that the number of seeds in the seed soaking bin 1 is continuously matched with the carrying capacity of the seed soaking bin 1.

[0110] 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 and fall into the seed outlet and enter the seed collection box 83. The water flowing out from the eddy current water outlet pipe 3 and the overflow pipe 4 passes through the seed screening grid 82 to screen out the seeds, and then passes through the filter grid 84 to screen out the impurities and then falls to the bottom inside the screening box 81. Subsequently, the water enters the circulating water pump 91 through the return pipe 87. After being pressurized by the circulating water pump 91, it is sent into the seed soaking bin 1 through the delivery pipe for recycling.

[0111] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
