Description

Technical Field

[0001] This application relates to the technical field of breeding, and in particular to a seed soaking device for agricultural seed selection. Background Technology

[0002] Currently, in agricultural seed breeding, seed soaking is a crucial pretreatment step to improve germination rate and disease resistance. Traditional methods often involve manual soaking or static treatment in simple containers, which suffers from problems such as large fluctuations in water temperature, insufficient dissolved oxygen, and uneven distribution of pesticides, resulting in low seed water absorption efficiency and poor germination uniformity. Especially for high-value breeding materials, the inability to achieve precise temperature control and circulating oxygenation can easily lead to seed mold or localized pesticide damage.

[0003] In existing technologies, a seed soaking box is generally used. When using it, warm water is poured into the seed soaking box, and then the seeds are placed in the seed soaking box so that the warm water submerges the seeds. Then, the seeds are turned over by manually stirring or turning them over so that the seeds are in full contact with the water and achieve a better soaking effect.

[0004] However, the long soaking time and frequent manual intervention for turning the seeds, coupled with the relatively poor reliability of manual turning, resulted in poor soaking efficiency and uneven soaking of some seeds, leading to poor soaking results. Summary of the Invention

[0005] In order to improve the efficiency of seed soaking and reduce the impact on the soaking effect, this application provides a seed soaking device for agricultural seed breeding.

[0006] This application provides a seed soaking device for agricultural seed breeding, which adopts the following technical solution:

[0007] A seed soaking device for agricultural seed breeding, comprising:

[0008] A seed soaking box, with an internal soaking space, is used to hold water for soaking seeds;

[0009] A partition frame is provided inside the seed soaking tank;

[0010] The supporting net is detachably connected to the partition frame, and is bucket-shaped, forming a supporting surface for placing seeds;

[0011] Multiple airbags are installed and connected by connecting ropes to support the bottom of the support net;

[0012] The jetting mechanism, located inside the seed soaking tank, impacts the airbags, causing the airbags to shake and thus the supporting net to shake.

[0013] The temperature control mechanism, located on the inner wall of the soaking tank, is used to heat the water.

[0014] By adopting the above technical solution, during seed soaking, the supporting net is first connected to the partition frame, and seeds are placed on the supporting net, causing it to hang down in a bucket shape and contact the airbag on the partition frame. Then, water is poured into the soaking tank so that the water level submerges the seeds on the supporting net. Then, the chemical solution is added, and the water is heated by a temperature control mechanism to maintain the water at the temperature set for seed soaking. The soaking time is set according to the seed type to keep the seeds submerged. During the seed soaking process, the jet mechanism is activated to impact the airbag, causing the airbag to shake. The airbag causes the supporting net to shake, making the seeds move vertically, increasing the contact between water and seeds, and also keeping the seeds in a suspended state. This ensures that the seeds are in full contact with the water, improving the soaking effect, reducing manual intervention, and increasing soaking efficiency. Furthermore, the flexible support of the airbag reduces mechanical damage, and the airbag buffer and fluid drive reduce the seed breakage rate.

[0015] Optionally, the surface of the airbag is provided with guide fins.

[0016] By adopting the above technical solution, when the jet impacts the airbag, the water flows through the guide fins to generate a vortex, which pushes the airbag to move laterally, converting the vertical jet kinetic energy into horizontal wave power, enhancing the swing amplitude of the airbag, improving the turning effect, keeping the seeds in a suspended state, and increasing the contact time with water.

[0017] Optionally, the jet mechanism includes:

[0018] Centrifugal pump, with its inlet connected to the lower part of the seed soaking tank;

[0019] A multi-directional nozzle assembly is located at the bottom of the seed soaking tank. Two sets are provided, each corresponding to one of the two air bladders at the end of the connecting rope. The two sets of multi-directional nozzle assemblies are connected to the centrifugal pump through a pulse solenoid valve, and the two sets of multi-directional nozzle assemblies spray at intervals.

[0020] By adopting the above technical solution, a centrifugal pump extracts liquid from the bottom of the tank, and then a pulse solenoid valve controls two sets of nozzles to open and close alternately (e.g., left spray for 0.5 seconds → stop for 0.3 seconds → right spray for 0.5 seconds), which targets and stimulates the end airbags to form a "push-pull" effect, maintaining continuous mechanical waves; this causes multiple airbags to push the carrier net to sway in a wave-like manner, increasing the flow state of the seeds, accelerating contact with water, and ensuring thorough and uniform mixing, thus shortening the overall soaking time.

[0021] Optionally, a counterweight is provided on the airbag near the end of the connecting rope, so that the multiple airbags are in a "W" shape in the free state.

[0022] By adopting the above technical solution, the counterweight causes the end airbag to hang naturally, forming a "W" shape in its free state, with the peaks and troughs of the jet alternating regularly during impact. The pre-set waveform foundation reduces startup energy consumption and the additional energy required for airbag fluctuation. Furthermore, this setting supports the carrying net, making it similar in shape, reducing the complete aggregation of seeds at the bottom of the bucket-shaped structure, thus dispersing the seeds, ensuring uniform contact between the seeds and water, improving soaking efficiency and effect, and ensuring that all seeds are fully in contact with water.

[0023] Optionally, the partition frame slides vertically on the soaking tank.

[0024] By adopting the above technical solution, when the supporting net sways, the vertical sliding of the partition frame along the trough wall, combined with the swaying of the airbag, increases the swaying of the seeds by the buoyancy of the water and the weight of the seeds, thus eliminating the risk of fatigue fracture caused by rigid constraints.

[0025] Optionally, the soaking tank is provided with a shaking component, the shaking component comprising:

[0026] A support ring is provided on the seed soaking box to support the partition frame, and a sliding hole is provided.

[0027] The sliding rod slides within the sliding hole on the support ring;

[0028] A spring, disposed within the sliding hole and connected to the sliding rod, is used to cause the sliding rod to sway when subjected to impact.

[0029] By adopting the above technical solution, when the jet is applied, the water flow impacts the airbag, causing the airbag to shake the supporting net. At the same time, the water in the soaking tank is disturbed, and the impact force causes the partition frame to move upward, causing the spring to accumulate elastic potential energy, which in turn causes the partition frame to shake. The spring releases energy to amplify the shaking amplitude. The pulse jet is converted into continuous mechanical vibration, which improves the shaking effect, further improves the soaking efficiency, and enhances the soaking effect of the seeds.

[0030] Optionally, the top of the sliding rod is provided with a hemispherical boss, and a groove is opened at the corresponding position at the bottom of the partition frame. The boss and the groove are fitted together to form a universal joint structure.

[0031] By adopting the above technical solution, when the partition frame sways under the elastic potential energy of the spring, the resistance of the water causes the partition frame to sway left and right and up and down, forming a three-dimensional sway. This makes the seeds stay in a suspended state for a longer time, while increasing the movement between the seeds, allowing more water to come into contact with the seeds, thus improving the soaking effect and efficiency.

[0032] Optionally, the counterweight has a permanent magnet embedded inside, and the bottom of the partition frame is provided with an electromagnet array, which generates a magnetic field that attracts or repels the permanent magnet when energized.

[0033] By adopting the above technical solution, when the partition frame moves upward, the electromagnet is energized to repel the permanent magnet, increasing the swaying of the partition frame and forming an gravitational field, which reduces the reduction of the lifting force by the partition frame's own weight and improves the absorption of swaying energy.

[0034] Optionally, the multi-directional nozzle assembly can intermittently spray at both ends of the length direction of a single airbag.

[0035] By employing the above technical solution, spraying is applied to both ends of the airbag, causing the airbag to oscillate in three dimensions. Combined with the oscillation of the partition frame, this improves the seed soaking effect and efficiency.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. The jet mechanism impacts the airbag, causing it to shake. The airbag then moves the supporting net, causing the seeds to move vertically. This increases the contact between water and seeds, and also keeps the seeds in a suspended state. This ensures full contact between the seeds and water, improving the soaking effect and reducing human intervention, thus increasing soaking efficiency. Furthermore, the flexible support of the airbag reduces mechanical damage, and the airbag cushioning and fluid drive reduce the seed breakage rate.

[0038] 2. This causes the partition frame to sway left, right, up, and down, creating a three-dimensional swaying motion. This prolongs the time the seeds remain suspended and increases the movement between the seeds, allowing more water to come into contact with them, thus improving the soaking effect and efficiency.

[0039] 3. Spraying at both ends of the airbag creates a three-dimensional shaking motion, which, combined with the shaking of the partition frame, improves the seed soaking effect and efficiency. Attached Figure Description

Detailed Implementation

[0044] The following combination Figures 1 to 3 This application will be described in further detail.

[0045] This embodiment discloses a seed soaking device for agricultural seed breeding.

[0046] Reference Figure 1 and Figure 2 This is a seed soaking device for agricultural seed breeding. The device achieves efficient and low-loss seed soaking through jet-driven airbag 400 fluctuations in conjunction with temperature control. It includes a soaking tank 100, a partition frame 200, a support net 300, airbags 400, connecting ropes 410, a jetting mechanism 500, and a temperature control mechanism 600. Initially, the support net 300 is mounted on the partition frame 200, and the seeds hang downwards in a bucket shape due to gravity. Multiple airbags 400 are connected in series via the connecting ropes 410 and support the bottom of the support net 300. After the soaking solution is injected, the temperature control mechanism 600 maintains a constant temperature, and the jetting mechanism 500 impacts the airbags 400, generating mechanical waves that cause the seeds to tumble three-dimensionally, achieving uniform soaking.

[0047] The soaking tank 100 is a stainless steel rectangular tank with a rotating cover 900 on the top. The inner wall is fitted with a temperature control mechanism 600, which includes a heating element and a temperature sensor. Heating elements are integrated on both sides of the tank and at the bottom. The heating elements are connected to the temperature sensor through a PID controller. The sensor probe extends to the middle of the soaking solution. The water temperature is maintained at 25±0.5℃ (rice) or 30±0.5℃ (corn) or the temperature can be set as needed.

[0048] The partition frame 200 is an aluminum alloy frame, and a swaying component 800 is installed on the side wall near the bottom wall of the seed soaking tank 100. The swaying component 800 is movably set inside the seed soaking tank 100. The support net 300 is a nylon woven bucket-shaped net. The partition frame 200 has a slot, and the support net 300 has multiple buckles 310. The buckles 310 are inserted into the slots of the partition frame 200 to achieve a detachable connection. The mesh size is 0.8mm (rice) or 1.5mm (corn). When hanging naturally, the side wall inclination angle is 35°~45°, and the bottom forms a seed support surface.

[0049] The airbags 400 are made of silicone and are connected in groups of eight via connecting ropes 410. The connecting ropes 410 have slight elasticity and can be made of nylon or rubber. The airbags 400 are arranged in parallel at the bottom of the support net 300, with the center of each end airbag 400 15cm from the edge of the partition frame 200. Each airbag 400 has six polyurethane fins arranged radially on its surface. The end of the fin away from the airbag 400 is inclined towards the center of the soaking tank 100, with a fin height of 8mm and an inclination angle of 20°. A counterweight 700 is installed on the third airbag 400 closest to the side wall of the soaking tank 100. The airbags 400 with the counterweight 700 reach the side wall of the soaking tank 100 every two airbags 400, causing the multiple airbags 400 and connecting ropes 410 to hang down, forming a "W" shape in the water (the trough sinks 5cm).

[0050] The counterweights 700 are located at both ends of the airbag 400, and can correspond vertically to the outer frame of the partition frame 200. A magnetic control component is set on the counterweights 700, which includes a permanent magnet and an electromagnet array. The permanent magnet is embedded in the counterweights 700 and is made of NdFeB material. The electromagnet array is located at the bottom of the partition frame 200. When energized, the attractive force mode (current in the forward direction) enhances the amplitude of the "W" waveform. The repulsive force mode (current in the reverse direction) and the jetting force of the jetting mechanism 500 combine to drive the partition frame 200 to float up, so that the partition frame 200 can be easily moved upward.

[0051] The jetting mechanism 500 includes a centrifugal pump 510, a multi-directional nozzle assembly 520, and a pulse control valve. The centrifugal pump 510 is located outside the soaking tank 100, and its inlet is connected to the bottom filter of the tank. There are two sets of multi-directional nozzle assemblies 520, each consisting of two sets of titanium alloy nozzles installed at the bottom of the tank and aligned with the end airbags 400, facing the fins. Each multi-directional nozzle assembly 520 includes multiple nozzles and is equipped with a solenoid valve for easy individual control.

[0052] It features two spray modes: alternating spray from two sets of nozzles (left spray 0.5s → right spray 0.5s); and intermittent spray from both ends of a single airbag 400 (left end spray 0.3s → stop 0.2s → right end spray 0.3s).

[0053] Reference Figure 3The swaying assembly 800 includes a support ring 810, a sliding rod 820, a spring 830, and a universal joint structure. The support ring 810 is fixed to the soaking tank 100 and has four sliding holes evenly distributed around its circumference. The sliding rod 820 is a chrome-plated steel rod that slides within the sliding holes. A hemispherical boss 840 is provided at its top. A groove 210 is formed on the side wall of the partition frame 200 near the sliding rod 820. The groove 210 and the boss 840 are fitted together to form a universal joint structure, allowing... The partition frame 200 can rotate within the seed soaking box 100 along the width direction of the seed soaking box 100; the spring 830 is sleeved on the sliding rod 820 and located in the sliding hole, with a pre-compression of 10mm; the sliding rod 820 is provided with a sliding plate 850, which slides in the sliding hole; one end of the spring 830 is connected to the bottom of the sliding hole, and the other end is connected to the sliding plate 850, and pushes the sliding plate 850 to slide away from the bottom wall of the seed soaking box 100.

[0054] The implementation principle of this application embodiment is as follows: Seed loading: The carrier net 300 is connected to the partition frame 200, and then 20 kg of seeds are loaded. The carrier net 300 hangs down in a bucket shape; Water injection: The soaking solution is injected until the seeds are submerged by 5 cm. Then, according to the design requirements, the temperature control mechanism 600 is started to maintain a constant temperature of 30°C; Jetting: The centrifugal pump 510 is started, and the pulse solenoid valve controls the multi-directional nozzle group 520 to spray alternately. The water flow impacts the end airbags 400; the guide fins convert the vertical jet into horizontal thrust, and the multiple airbags 400 oscillate in a "W" shape or A wave-like surge occurs; the connecting rope 410 transmits mechanical waves, causing the carrying net 300 to tumble the seeds; under the surge of water and the propulsion of the jet, the partition frame 200 slides vertically, and the spring 830 extends and stretches to store energy; the spring 830 releases to push the universal joint structure to oscillate in three dimensions, thus prolonging the seed suspension time; if the seed soaking uniformity is insufficient, the electromagnet array switches between repulsion and attraction modes to increase the wave amplitude; the jet mode is switched to impact the end of the airbag 400, causing the airbag 400 to twist and swing, making the seeds vortex.

[0055] The above settings make the distribution of the agent and its contact with the seeds more uniform, and the airbag 400 acts as a buffer to reduce direct action on the seeds and reduce mechanical damage to the seeds. The fluctuating water accelerates the penetration of water molecules into the seeds.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
