Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to a rice planting seed soaking and germination device. Background Technology

[0002] In the process of soaking and germinating rice seeds, the soaking step enables the seeds to absorb sufficient water, activates the enzymes within the seeds, and causes the plumule and radicle to begin to sprout and grow, shortening the germination time, increasing the seed germination rate, and helping to achieve the goal of "fast, uniform, even, and strong" germination. Scientific soaking and germination can ensure that rice seed germination is not affected by adverse weather conditions, shorten the emergence time, make rice seedlings uniform and the seedlings strong, prevent seed rot and seedling rot, and improve the survival rate of seedlings. In cold rice producing areas, due to the impact of low temperature damage, the reliance on soaking and germination technology is even more prominent. The soaking and germination step can compensate for about 100℃ of accumulated temperature, which is crucial for improving the yield and quality of rice in cold regions.

[0003] Existing rice seed soaking and germination equipment is not widely used by family-style farmers, which makes it difficult to effectively improve the convenience of family-style rice growers in the seed soaking and germination process, and is not conducive to the healthy development of agricultural and rural planting industry. Therefore, we propose a seed soaking and germination device.

[0004] An existing patent (publication number: CN221354938U) discloses a seed soaking and germination device. By setting a manual filter for shriveled grains, it can improve the convenience of intercepting shriveled grains during the seed soaking and germination process. By setting an openable and closable pipe, it greatly facilitates the separation of shriveled grains from rice seeds, thus improving the convenience of seed soaking and germination. By setting a simple, household-style seed soaking and germination device, it can reduce the cost of seed soaking and germination for farmers when planting rice, which is conducive to the healthy development of rice planting in agriculture and rural areas.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, current rice planting soaking and germination devices typically lack an automatic dynamic screening structure, making it difficult to efficiently separate empty grains from impurities. This results in low screening efficiency, a large amount of impurity residue, and affects seed purity and the basic quality of subsequent soaking and germination. Furthermore, the soaking and germination processes often require manual switching, making it difficult for seeds to evenly contact the soaking solution and to stably control environmental parameters such as temperature and humidity. Consequently, seeds tend to accumulate, leading to uneven water absorption, large environmental fluctuations, and affecting the uniformity of germination and survival rate.

[0006] To address this, a rice seed soaking and germination device is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a rice seed soaking and germination device that solves the problems of existing rice seed soaking and germination devices, which usually lack an automatic dynamic screening structure, making it difficult to efficiently separate empty grains from impurities. This results in low screening efficiency, a large amount of impurity residue, and affects the purity of seeds and the basic quality of subsequent soaking and germination. Moreover, the soaking and germination processes often require manual switching, which makes it difficult for seeds to evenly contact the soaking solution and to stably control environmental parameters such as temperature and humidity. As a result, seeds tend to accumulate, leading to uneven water absorption, large environmental fluctuations, and affecting the uniformity of germination and the survival rate.

[0009] Preferably, the immersion treatment assembly includes a fixed plate fixedly connected inside the germination box, a rotary motor fixedly connected to the top of the fixed plate, and a silicone agitator fixedly connected to the output end of the rotary motor.

[0010] Preferably, a flow guide inclined seat is fixedly connected to the bottom of the germination box, and an inclined graded filter screen is fixedly connected to the top of the flow guide inclined seat. The inclined graded filter screen is located at the bottom of the silica gel agitator.

[0011] Preferably, a liquid storage tank is fixedly connected to the top of the base, and a conveying nozzle is connected to the outside of the liquid storage tank. The conveying nozzle is located on top of the inclined graded filter screen, and a water pump is provided on the outside of the conveying nozzle.

[0012] Preferably, a limiting rod is fixedly connected to the outer side of the fixed base, and a connecting rod is fixedly connected to the outer side of the screening cylinder, with the connecting rod rotatably connected to the limiting rod.

[0014] Preferably, a control motherboard is provided on the outside of the germination box, and a temperature sensor is connected inside the control motherboard.

[0015] Preferably, the top of the germination box is rotatably connected to a top cover, and a humidity sensor is provided at the bottom of the top cover.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This application achieves automatic screening of rice seeds and precise separation of empty grains and impurities through a pre-treatment screening component, thereby improving seed purity and the basic quality of subsequent soaking and germination. Compared with the time-consuming, labor-intensive, and incomplete screening in traditional rice soaking and germination devices, this component drives the screening plate to move up and down in the screening cylinder through a drive motor, realizing the dynamic screening function of seeds. This solves the problems of low efficiency of manual screening affecting planting progress, incomplete screening causing empty grains to rot and contaminate high-quality seeds, and cumbersome screening operation reducing the convenience of home planting.

[0018] 2. This application achieves uniform seed soaking and precise control of the germination environment through the soaking and germination treatment component, thereby improving the seed germination rate and germination uniformity. Compared with traditional rice seed soaking and germination devices, where seeds tend to accumulate, leading to uneven soaking and difficulty in controlling environmental parameters, resulting in rotten seeds and rotten germination, this component dynamically agitates the seeds through a silicone agitator, precisely supplies the soaking solution through a storage tank and delivery nozzle, and controls the main board in conjunction with temperature and humidity sensors to adjust the environment in real time. This realizes an integrated intelligent operation function for soaking and germination, solving the problems of uneven water and fertilizer absorption due to seed accumulation, large temperature and humidity fluctuations affecting germination stability, and frequent manual adjustments increasing labor intensity in traditional methods.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 The present invention provides the following technical solution:

[0028] A rice seed soaking and germination device includes a base 1, a germination box 2 fixedly connected to the top of the base 1, a pretreatment screening component 4 arranged on the left side of the germination box 2, and a soaking and germination treatment component 5 arranged inside the germination box 2. The pretreatment screening component 4 includes a pretreatment cylinder 401 fixedly connected to the left side of the germination box 2, a sealing cover 402 arranged on the top of the pretreatment cylinder 401, a fixed base 403 fixedly connected to the bottom of the sealing cover 402, a drive motor 404 fixedly connected to the outside of the fixed base 403, a transmission rod 405 arranged at the output end of the drive motor 404, the transmission rod 405 being rotatably connected to the fixed base 403, a connecting support rod 406 fixedly connected to the inside of the transmission rod 405, a screening plate 407 fixedly connected to the bottom of the connecting support rod 406, and a screening cylinder 408 arranged on the outside of the screening plate 407.

[0029] In this embodiment: by starting the drive motor 404, the output end of the drive motor 404 drives the transmission rod 405 to rotate around the rotating shaft of the fixed base 403. The connecting support rod 406 on the inner side of the transmission rod 405 moves synchronously with the transmission rod 405, thereby pulling the bottom screening plate 407 to move up and down inside the screening cylinder 408. When the screening plate 407 rises, it will lift the seeds upward, so that the seeds are in a loose state inside the screening cylinder 408. Some small-sized shriveled grains and impurities will pass through the sieve holes in the wall of the screening cylinder 408 under the action of gravity and fall into the bottom of the pretreatment cylinder 401. When the screening plate 407 descends, it will squeeze the seeds, causing more unqualified particles hidden inside the seed pile to separate through the sieve holes. Through this continuous up and down turning and screening, the seeds that are left in the screening cylinder 408 are all high-quality seeds with full grains and qualified grain size, providing a high-quality raw material basis for subsequent soaking and germination.

[0030] Specifically, such as Figure 3 As shown, the immersion treatment component 5 includes a fixed plate 501 fixedly connected inside the germination box 2. A rotary motor 502 is fixedly connected to the top of the fixed plate 501, and a silicone agitator 503 is fixedly connected to the output end of the rotary motor 502.

[0031] Specifically, such as Figure 3 As shown, a flow guide sloping seat 504 is fixedly connected to the bottom of the germination box 2, and an inclined grading filter 505 is fixedly connected to the top of the flow guide sloping seat 504. The inclined grading filter 505 is located at the bottom of the silicone agitator 503.

[0032] Specifically, such as Figure 3 As shown, a liquid storage tank 506 is fixedly connected to the top of the base 1. A conveying nozzle 507 is connected to the outside of the liquid storage tank 506. The conveying nozzle 507 is located on the top of the inclined graded filter screen 505. A conveying water pump 508 is provided on the outside of the conveying nozzle 507.

[0033] In this embodiment: Pre-treated high-quality seeds enter the germination chamber 2 and fall onto the inclined grading filter 505. The fixed plate 501 inside the germination chamber 2 provides stable support for the rotary motor 502. After the rotary motor 502 is started, its output end drives the silicone agitator 503 to rotate at a uniform speed. The silicone blades are soft and can gently separate the piled seeds when they come into contact with the seeds, ensuring that the seeds are evenly distributed, while avoiding scratching the seed coat and affecting germination activity. The inclined grading filter 505 is at a certain angle to the horizontal plane and has sieve holes of different sizes on its surface. As the silicone agitator 503 moves... When the seeds are turned over, they will slowly slide along the inclined surface of the filter screen. During this process, a small amount of small impurities will pass through the sieve holes and fall into the guide slope 504 below. The guide slope 504 is also inclined, which can guide the impurities and excess liquid to one side of the bottom of the germination box 2. The liquid storage tank 506 at the top of the base 1 contains soaking solution or clean water. When soaking is required, the water pump 508 outside the conveying nozzle 507 is started. The liquid in the storage tank 506 will be evenly sprayed onto the seed surface on the inclined grading filter screen 505 through the conveying nozzle 507, ensuring that each seed can fully contact the liquid and improve the uniformity of water absorption.

[0034] Specifically, such as Figure 5 As shown, a limiting rod 6 is fixedly connected to the outer side of the fixed base 403, and a connecting rod 7 is fixedly connected to the outer side of the screening cylinder 408. The connecting rod 7 is rotatably connected to the limiting rod 6.

[0035] Specifically, such as Figure 4 As shown, the outer side of the germination box 2 is connected to the discharge pipe 8, and the outer side of the discharge pipe 8 is equipped with a control valve 9.

[0036] In this embodiment: By setting a limiting rod 6 and a connecting rod 7, when seeds need to be added to the sieve cylinder 408, the sealing cover 402 is lifted upwards, and the fixed seat 403 rises accordingly. At this time, the limiting rod 6, through its rotational cooperation with the connecting rod 7, can both drive the sieve cylinder 408 to move synchronously out of the pretreatment cylinder 401 and maintain a stable posture of the sieve cylinder 408 during movement, preventing seeds from spilling or the sieve cylinder 408 from tilting due to shaking. By setting a discharge pipe 8 and a control valve 9, the discharge pipe 8 on the outside of the germination box 2 is used for... The waste liquid in the germination box is discharged, and the control valve 9 on the outside is responsible for controlling the opening and closing of the discharge pipe 8. During the soaking process, when the soaking solution needs to be replaced or too much excess liquid accumulates in the box, the operator can manually open the control valve 9. At this time, the waste liquid at the bottom of the germination box 2 will flow out along the discharge pipe 8 under the guidance of the guide inclined seat 504, avoiding the accumulation of waste liquid in the box and causing the seeds to deteriorate during soaking. When the waste liquid is discharged or does not need to be discharged, the control valve 9 can be closed to block the liquid flow and ensure that the amount of liquid in the germination box 2 meets the requirements for soaking or germination.

[0037] Specifically, such as Figure 6As shown, a control board 3 is installed on the outside of the germination box 2, and a temperature sensor is installed inside the control board 3.

[0038] Specifically, such as Figure 6 As shown, a top cover 10 is rotatably connected to the top of the germination box 2, and a humidity sensor 11 is provided at the bottom of the top cover 10.

[0039] In this embodiment: By setting the control motherboard 3, during the seed germination process, the temperature sensor continuously transmits the temperature data inside the chamber to the control motherboard 3. When the temperature is detected to be lower than the suitable temperature required for seed germination, the control motherboard 3 will automatically start the heating device to raise the temperature inside the chamber, ensuring that the temperature inside the germination chamber 2 is always stable within the optimal range for seed germination. This avoids burning the seedlings due to excessively high temperatures or delaying the germination speed due to excessively low temperatures, significantly improving the stability and success rate of germination. By setting the top cover 10 and the humidity sensor 11, closing the top cover 10 during the soaking and germination process can reduce the evaporation of water inside the chamber, helping to maintain a high humidity environment. At the same time, the humidity sensor 11 will feed back the monitored humidity data to the control motherboard 3 in real time. When the humidity is lower than the suitable value, the control motherboard 3 will start the humidification device to replenish the water.

[0040] Working Principle: In using this rice seed soaking and germination device, the seeds undergo pre-treatment screening first. At this stage, the sealing cap 402 must be removed from the pre-treatment cylinder 401. Since the limiting rod 6 on the outside of the fixed base 403 is rotatably connected to the connecting rod 7 on the outside of the screening cylinder 408, when the sealing cap 402 is lifted upwards, the fixed base 403, through the linkage of the limiting rod 6 and the connecting rod 7, will move the screening cylinder 408 out of the pre-treatment cylinder 401. After removing the screening cylinder 408, the rice seeds to be treated can be added to it. The seeds will be temporarily stored on the screening plate 407. Then, the sealing cap 402, along with the screening cylinder 408, is placed back into the pre-treatment cylinder 401, ensuring that the sealing cap 402 and the pre-treatment cylinder 408 are properly aligned. 01. A tight fit is ensured to prevent seeds or impurities from leaking out during subsequent sieving. After seed loading is complete, the drive motor 404 on the outside of the fixed base 403 is activated. The output of the drive motor 404 drives the transmission rod 405 to rotate. Since the transmission rod 405 is rotatably connected to the fixed base 403, the connecting support rod 406 fixed inside it moves synchronously with the transmission rod 405, thereby driving the bottom sieving plate 407 to move up and down reciprocally inside the sieving cylinder 408. When the sieving plate 407 moves up and down, it continuously flips the seeds inside the sieving cylinder 408, keeping the seeds in a dynamic state. The cylinder wall of the sieving cylinder 408 has sieve holes of a specific diameter. When the sieving plate 407 moves up and down, the seeds are lifted upwards, and some small seeds are separated. Empty grains or impurities will leak out from the sieve holes of the sieve cylinder 408 due to gravity and tumbling action, falling into the bottom of the pretreatment cylinder 401. This achieves pretreatment sieving of the seeds, ensuring that the seeds remaining on the sieve plate 407 are all high-quality seeds with full grains and meeting the particle size requirements, laying a good foundation for subsequent soaking and germination. After pretreatment sieving, the high-quality seeds will enter the germination box 2 for soaking and germination treatment. The fixed plate 501 in the germination box 2 provides stable support for the rotary motor 502. After starting the rotary motor 502, its output end will drive the silicone agitator 503 to rotate continuously. The silicone agitator 503 is soft in texture, which can avoid damaging the seeds during the agitation process and ensure that the seeds are evenly distributed, preventing uneven soaking caused by local accumulation. The bottom of the germination box 2... The inclined guide seat 504 is tilted, and its top inclined grading filter 505 is located directly below the silica gel agitator 503. Seeds that have undergone preliminary screening fall onto the inclined grading filter 505. As the silica gel agitator 503 agitates, the seeds slide continuously on the filter. The different pore sizes on the filter surface further filter out any small impurities that may remain. These impurities fall through the filter into the inclined guide seat 504 and then converge downwards along the tilt angle of the inclined guide seat 504. The liquid storage tank 506 at the top of the base 1 stores soaking solution or clean water. When soaking is required, the delivery water pump 508 is activated, and the liquid in the storage tank 506 is delivered to the top of the inclined grading filter 505 through the delivery nozzle 507, where the liquid is evenly sprayed onto the seeds.This ensures the seeds fully absorb water, while excess liquid flows through the filter screen and into the bottom of the germination chamber 2 via the guide bracket 504. When it's necessary to drain the waste liquid or replace the soaking solution, open the control valve 9 on the outside of the discharge pipe 8, and the waste liquid will drain out along the discharge pipe 8, preventing waste liquid from accumulating inside the chamber and affecting seed growth.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
