Description

Technical Field

[0001] This utility model relates to the field of corn cultivation, and in particular to a corn seed initiation device. Background Technology

[0002] Under natural conditions, corn seeds may germinate asynchronously and have a low emergence rate due to uneven water absorption, seed coat barrier, or adverse environmental conditions. In order to improve the survival rate and emergence rate of seeds, it is necessary to induce seed growth before sowing, that is, to treat seeds with hydration through various means such as soaking and hormone stimulation.

[0003] Currently, seed initiation is generally carried out manually, requiring operators to have a high level of skill; otherwise, the initiation effect will be affected. The corn seed initiation device can perform various corn seed initiation operations according to the set degree, without requiring operators to have extensive seed initiation experience.

[0004] Currently, a Chinese patent with announcement number CN109105374A and announcement date of January 1, 2019, proposes a corn seed initiator and its preparation method, as well as a method for promoting corn seed germination against low temperature. The method requires multiple operations such as seed disinfection, soaking, initiator preparation, washing, and drying, and also has time requirements.

[0005] When performing corn seed initiation according to the above method, operators need to properly control the time and process of each step to improve the seed initiation effect. However, for those without operating experience or who are not proficient in the operation, the time intervals and process switching between each operation step are quite difficult. If there are operational errors or improper time control, it will have an adverse effect on the seed initiation effect. Utility Model Content

[0006] In order to reduce the operational difficulty of the seed initiation process and improve the effect of seed initiation, this utility model provides a corn seed initiation device.

[0007] This utility model provides a corn seed initiation device, which adopts the following technical solution: A corn seed initiation device includes: a seed soaking tank, a water replenishment tank, a liquid replenishment tank, a concentration sensor, a stirring assembly, a lifting assembly, and a controller. The concentration sensor and the stirring assembly are both located inside the seed soaking tank. The water replenishment tank and the liquid replenishment tank are both connected to the seed soaking tank. Water pumps are installed between the water replenishment tank and the seed soaking tank, and between the liquid replenishment tank and the seed soaking tank. The lifting assembly is located inside the seed soaking tank and is used to hold the seeds. The concentration sensor, the stirring assembly, the lifting assembly, and the water pumps are all electrically connected to the controller.

[0008] By adopting the above technical solution, the soaking tank and the water replenishment tank are used to store clean water, while the replenishment tank is used to store the initiator. After the user adds clean water to the soaking tank, the controller, according to the set parameters, controls the water pump between the replenishment tank and the soaking tank to start, allowing the initiator to flow into the soaking tank for dosage adjustment. During the initiator dosage adjustment process, the concentration sensor will detect the solution concentration in real time, and control the water replenishment tank to add clean water to the soaking tank and the replenishment tank to add initiator to the soaking tank through the two water pumps respectively, thereby adjusting the concentration of the solution in the soaking tank. At the same time, the stirring component will stir the soaking... The liquid in the soaking tank is stirred to promote the mixing of water and initiator, making the concentration of the initiator in the soaking tank more uniform. After the initiator in the soaking tank is prepared, the lifting component will move the corn seeds downwards to immerse them in the prepared initiator in the soaking tank for timed initiation treatment. After the set time, the lifting component will lift the corn seeds up, allowing them to come out of the initiator in the soaking tank and dry. While the corn seeds are soaking in the initiator in the soaking tank, the stirring component will also stir them periodically to keep the concentration of the initiator uniform.

[0009] In this way, when using the device, simply place the corn seeds on the lifting assembly, add clean water to the soaking tank and the water replenishment tank, add initiator to the liquid replenishment tank, and then start the corn seed initiation device to carry out automated seed initiation treatment. This achieves automatic coordinated operation of soaking, replenishment and stirring, eliminating the trouble of manual timing and process switching. It also reduces operational errors caused by insufficient operator experience and improves the uniformity and success rate of seed initiation.

[0010] Optionally, the lifting assembly includes a cover, a drive assembly, a lifting frame, and a filter plate. The cover is disposed above the soaking tank, the drive assembly is disposed on the cover, the lifting frame is slidably disposed on the cover in a vertical direction, the drive assembly is connected to the lifting frame in a transmission manner, and the filter plate is disposed on the lifting frame, and the filter plate is provided with filter holes.

[0011] By adopting the above technical solution, the filter plate is installed on the lifting frame. The drive component drives the lifting frame to move, causing the filter plate and the corn seeds on the filter plate to move up and down. When the drive component drives the lifting frame to the lowest position, the lifting frame and the filter plate are located in the soaking tank below the cover. At this time, the filter plate enters the liquid in the soaking tank. When the drive component drives the lifting frame to the highest position, the lifting frame and the filter plate are located above the cover. At this time, the lifting frame and the filter plate are exposed to the air above the cover. The liquid on the filter plate and the seeds flows down from the filter holes of the filter plate and gradually flows into the soaking tank. In this way, the lifting frame can move downwards to carry the seeds into the liquid in the soaking tank for initiation treatment via the filter plate, and the lifting frame can move upwards to carry the seeds out of the soaking tank via the filter plate, allowing the seeds to be exposed to the air to dry. On the one hand, it can soak more seeds in the soaking tank with limited space, improving space utilization; on the other hand, by setting the lifting frame on the cover that is separate from the soaking tank, the seeds can be taken away simply by removing the cover, making it easier to place the seeds on the filter plate of the lifting frame or to remove the seeds from the filter plate.

[0012] Optionally, the lifting frame is provided with multiple layers of filter plates along the vertical direction, and the filter plates are detachably installed on the lifting frame.

[0013] By adopting the above technical solution, the multi-layer filter plate can be detached and installed, allowing multiple layers of seeds to be placed on the lifting frame at the same time when there are many seeds. During use, users can install or remove the filter plate according to the number of seeds. When immersing the seeds in the initiator in the soaking box, it can reduce the probability that the seeds in the middle cannot fully absorb the initiator due to the dense stacking of seeds, thus improving the uniformity of seed initiation.

[0014] Optionally, the drive assembly includes a motor, a worm gear, and a rack. The motor is fixedly mounted on the cover, the worm gear is rotatably mounted on the cover and fixedly connected to the output shaft of the motor, and the rack is fixedly mounted on the lifting frame. The rack is arranged in a vertical direction and meshes with the worm gear.

[0015] By adopting the above technical solution, the motor drives the worm gear to rotate, and the worm gear drives the rack to move up and down, thereby causing the lifting frame to rise and fall relative to the cover. During the lifting process, the worm gear and rack structure provides a self-locking function, which can maintain the stability of the lifting. At the same time, the cooperation between the worm gear and rack can enable the small torque motor to provide greater lift, further improving the stability of the lifting frame.

[0016] Optionally, the lifting frame is also provided with a guide rail, and the cover is provided with a guide groove. Both the guide rail and the guide groove are arranged in a vertical direction, and the guide rail is slidably disposed in the guide groove.

[0017] By adopting the above technical solution, during the lifting frame's ascent or descent relative to the cover, the guide rail slides in the guide groove, which can guide the lifting frame to move vertically, keep the lifting frame aligned, and improve the stability of the lifting frame's movement.

[0018] Optionally, the top of the lifting frame is also provided with a baffle and a fan. The baffle is fixedly installed above the lifting frame and has ventilation holes. The fan is fixedly installed below the baffle and covers the ventilation holes.

[0019] By adopting the above technical solution, after the seeds are lifted out of the soaking box by the lifting frame, the fan starts to blow air through the ventilation holes to sweep the seeds on the lifting frame, accelerate the air flow, and make the seeds dry quickly, shortening the overall seed incubation time and improving efficiency.

[0020] Optionally, the baffle is also provided with a filter screen, which covers the ventilation hole.

[0021] By adopting the above technical solution, the filter screen covers the ventilation holes, which can filter the air; when the fan is working, the filter screen prevents dust and debris from entering the lifting frame, keeping the seeds clean, extending the fan's lifespan, and reducing maintenance needs.

[0022] Optionally, the stirring assembly includes a magnetic stirring base and a magnetic rotor. The magnetic stirring base is fixedly disposed at the bottom of the outside of the soaking tank, and the magnetic rotor is disposed inside the soaking tank.

[0023] By adopting the above technical solution, the magnetic stirring base generates a magnetic field outside the box, driving the magnetic rotor to rotate inside the box; during soaking, the rotor stirs the solution to keep it uniform, and after soaking is completed, the magnetic rotor can be directly removed, so that the magnetic rotor and the inside of the soaking box can be cleaned, making it easier to clean the inside of the soaking box.

[0024] In summary, this utility model has at least one of the following beneficial technical effects: To use this device, simply place the corn seeds on the lifting assembly, add water to the soaking tank and the water replenishment tank, add the initiator to the replenishment tank, and then start the initiation device for automated seed initiation. This eliminates the hassle of manual timing and process switching, while also reducing operational errors caused by insufficient operator experience and improving the uniformity and success rate of seed initiation.

[0025] By installing the lifting assembly on the cover, the lifting frame can move downwards to carry the seeds into the liquid in the soaking tank for initiation treatment via the filter plate, and the lifting frame can move upwards to carry the seeds out of the soaking tank via the filter plate, exposing the seeds to the air for drying. On the one hand, it can soak more seeds in the soaking tank with limited space, improving space utilization. On the other hand, by setting the lifting frame on the cover, which is separate from the soaking tank, the seeds can be taken away simply by removing the cover, making it easier to place the seeds on the filter plate of the lifting frame or to remove the seeds from the filter plate.

[0026] The multi-layer filter plate is designed for easy installation and removal, allowing users to install or remove the filter plate according to the number of seeds. This enables multiple layers of seeds to be placed on the lifting frame simultaneously when there are many seeds. When immersing seeds in the initiator in the soaking box, it reduces the probability that the seeds in the middle will not be able to fully absorb the initiator due to the dense stacking of seeds, thus improving the uniformity of seed initiation.

[0027] By installing a fan on the cover, after the seeds are lifted out of the soaking box by the lifting frame, the fan starts blowing air to sweep the seeds on the lifting frame, accelerating airflow and making the seeds dry quickly, shortening the overall seed incubation time and improving efficiency.

Detailed Implementation

[0030] The following combination Figures 1 to 4 The present invention will be described in further detail below.

[0031] This utility model discloses a corn seed initiation device. (Refer to...) Figures 1 to 2 A corn seed initiation device mainly includes: a seed soaking tank 100, a water replenishment tank 110, a liquid replenishment tank 120, a concentration sensor 130, a stirring assembly 200, a lifting assembly 300, and a controller 400. The concentration sensor 130 and the stirring assembly 200 are both located inside the seed soaking tank 100. The water replenishment tank 110 and the liquid replenishment tank 120 are both connected to the seed soaking tank 100. Water pumps 140 are installed between the water replenishment tank 110 and the seed soaking tank 100, and between the liquid replenishment tank 120 and the seed soaking tank 100. The lifting assembly 300 is located inside the seed soaking tank 100 and is used to hold the seeds. The concentration sensor 130, stirring assembly 200, lifting assembly 300, and water pumps are also included. All 140 units are electrically connected to the controller 400. In use, simply place the corn seeds on the lifting assembly 300, add clean water to the soaking tank 100 and the water replenishment tank 110, add initiator to the replenishment tank 120, and then start the corn seed initiation device. The controller 400 can automatically control the water pump 140 to turn on, so that the initiator flows into the soaking tank 100 for mixing. After mixing is completed, the lifting assembly 300 drives the seeds to descend and immerse them in the solution in the soaking tank 100 for initiation treatment. After a set time, the lifting assembly 300 drives the seeds to be lifted out of the solution in the soaking tank 100 and dried. The initiation treatment of the seeds is automated.

[0032] Reference Figure 2 and Figure 3 The soaking tank 100 is a hollow box. The inside of the soaking tank 100 is used to hold the initiator solution. The water tank 110 and the liquid replenishment tank 120 are both fixedly installed on one side of the soaking tank 100. The water tank 110 is used to store clean water and is connected to the soaking tank 100 through a pipe. The liquid replenishment tank 120 is used to store the initiator and is also connected to the soaking tank 100 through a pipe. Water pumps 140 are installed on the pipes between the water tank 110 and the soaking tank 100, and on the pipes between the liquid replenishment tank 120 and the soaking tank 100. When the water pumps 140 are turned on, the liquid in the water tank 110 and the liquid replenishment tank 120 flows into the soaking tank 100. When the water pumps 140 are turned off, the water tank 110, the liquid replenishment tank 120 and the soaking tank 100 are independent of each other.

[0033] Reference Figure 2 The seed soaking tank 100 is also equipped with a concentration sensor 130. The concentration sensor 130 is fixedly installed inside the seed soaking tank 100 on the side opposite to the water replenishment tank 110 and the liquid replenishment tank 120. It is used to detect the solution concentration in real time. In this embodiment, the concentration sensor 130 is a conductivity sensor. The conductivity sensor generates the corresponding solution concentration information by detecting the concentration of ions in the water.

[0034] Reference Figure 2The stirring assembly 200 includes a magnetic stirring base 210 and a magnetic rotor 220. The magnetic stirring base 210 is fixedly installed on the bottom of the outside of the soaking tank 100, with the bottom of the soaking tank 100 as a gap between the magnetic stirring base 210 and the soaking tank 100. The magnetic rotor 220 is placed at the bottom of the soaking tank 100 and is held still by the attraction of the magnetic stirring base 210. In this embodiment, the magnetic stirring base 210 contains a motor, a connecting rod, and two permanent magnets. The middle part of the connecting rod is fixedly connected to the output shaft of the motor. The two permanent magnets are respectively disposed at both ends of the connecting rod. The magnetic rotor 220 is made of magnetic material and has a capsule-shaped structure. The magnetic rotor 220 is in the form of stainless steel coated magnets to enhance the stirring effect. When the output shaft of the motor rotates, the connecting rod drives the two permanent magnets to rotate, thereby driving the magnetic rotor 220 to rotate inside the soaking tank 100.

[0035] Reference Figure 2 and Figure 3 The lifting assembly 300 includes a cover 310, a drive assembly 320, a lifting frame 330, a filter plate 340, and a baffle 350. The cover 310 is separate from the soaking box 100, and its two sides are connected to the outer wall of the soaking box 100 via fasteners. A lifting hole is provided in the middle of the cover 310, and the position of the lifting hole corresponds to the position of the soaking box 100. The lifting frame 330 is slidably disposed in the lifting hole in the vertical direction, and a baffle 350 is provided on the top of the lifting frame 330. The lifting frame 330 has a groove-shaped structure and is fixedly connected to the bottom of the cover 310. The size of the cover 310 is slightly larger than the lifting hole. The lifting frame 330 is placed to fall from the lifting hole. The lifting frame 330 has multiple support platforms inside. The filter plate 340 is placed on the support platform and fixed by the ear plates on both sides of the filter plate 340 being snapped into the slots of the support platform. The middle of the filter plate 340 is concave to accommodate more seeds. The bottom of the filter plate 340 is provided with filter holes 341 so that the solution adhering to the seeds above the filter plate 340 can drip from the filter holes 341. When the lifting frame 330 is installed in the lifting hole of the cover 310, the drive assembly 320 is connected to the lifting frame 330 for driving the lifting frame 330 to move up and down relative to the cover 310.

[0036] Reference Figure 4The lifting assembly 300 includes a motor 321, a worm gear 322, and a rack 323. The rack 323 is fixedly mounted vertically on the lifting frame 330. A vertically axial rotating shaft is provided on the cover 310, and the rotating shaft is rotatably mounted on the cover 310. The worm gear 322 is fixedly mounted on the rotating shaft and meshes with the rack 323. The motor 321 is fixedly mounted on the cover 310. A bevel gear is provided on the output shaft of the motor 321, and a bevel gear is also fixedly mounted on the corresponding rotating shaft. The two bevel gears mesh with each other, so that when the motor 321 rotates, it can drive the worm gear 322 to rotate through the bevel gear, thereby driving the rack 323 to move up and down, realizing the raising or lowering of the lifting frame 330 relative to the cover 310.

[0037] To increase the stability of the cover 310 when it rises or falls, guide rails 331 are provided on both sides of the lifting frame 330, and guide grooves 332 are provided on the corresponding cover 310. When the lifting frame 330 rises or falls, the guide rails 331 slide in the guide grooves 332, making the lifting frame 330 slide more stably.

[0038] To increase the drying speed of the seeds on the filter plate 340, a fan 360 is also installed below the baffle 350 at the top of the lifting frame 330. The fan 360 is fixedly installed at the bottom of the baffle 350, and the baffle 350 has a through ventilation hole 351. When the fan 360 rotates, air passes through the ventilation hole 351 of the baffle 350 and blows the seeds in the lifting frame 330 to speed up the drying speed of the seeds.

[0039] To improve the cleanliness of the seeds, a filter screen 370 is also installed over the ventilation holes 351 of the baffle 350.

[0040] The implementation principle of the corn seed initiation device in this embodiment of the utility model is as follows: During operation, the user fills the soaking tank 100 and the water replenishment tank 110 with clean water, adds the initiator to the replenishment tank 120, places the seeds on the filter plate 340 of the lifting assembly 300, then places the cover 310 above the soaking tank 100 and locks the cover 310 to the soaking tank 100 with the buckle, and finally starts the initiation device on the operation panel of the controller 400.

[0041] In the initiator concentration adjustment stage in the soaking tank 100: the controller 400 turns on the water pump 140 in the replenishment tank 120 to inject the initiator into the soaking tank 100. The concentration sensor 130 provides real-time feedback data. The controller 400 precisely adjusts the concentration of the initiator in the soaking tank 100 by alternately turning on and off the water pump 140 in the replenishment tank 110 and the replenishment tank 120. At the same time, the magnetic rotor 220 rotates to promote the mixing of the initiator with the water. Soaking stage: Motor 321 drives worm 322 to rotate, and worm 322 cooperates with rack 323 to drive lifting frame 330 to move down, so that the seeds on filter plate 340 are immersed in solution; during the soaking process, controller 400 starts stirring component 200 at regular intervals to maintain uniform concentration; Air drying stage: After the soaking time reaches the set time, the motor 321 drives the worm gear 322 to rotate in the opposite direction. The worm gear 322 and the rack 323 cooperate to drive the lifting frame 330 to move up and lift the seeds. The fan 360 starts. After the air passes through the filter screen 370 on the ventilation hole 351, the airflow blows away the liquid on the seed surface to dry the seeds. At the same time, the initiator attached to the seeds flows back to the soaking box 100 through the filter hole 341 for recycling. When initiating a large number of seeds, users can install multi-layer filter plates 340 on the lifting frame 330 to reduce the adverse effects on the initiation effect caused by excessive seed accumulation after the seeds enter the initiation solution.

[0042] In summary, the corn seed initiation device of this application only requires placing the corn seeds on the lifting assembly 300, adding clean water to the soaking tank 100 and the water replenishment tank 110, adding initiator to the replenishment tank 120, and then starting the initiation device to carry out automated seed initiation treatment. It is convenient to use, reduces operational errors caused by insufficient operator experience, and improves the uniformity and success rate of seed initiation.

[0043] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made according to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
