Description
Technical Field
[0001] The present invention relates to the technical field of agricultural planting, and specifically to an intelligent temperature-controlled seed soaking device for improving the germination rate of cotton seeds. Background Technique
[0002] As a key pretreatment step for improving the germination rate, soaking cotton seeds requires precise control of water temperature and humidity to promote seed water absorption and germination. Traditional seed soaking methods mostly rely on the natural temperature environment or simple heating devices (such as constant temperature water baths), and adjust the temperature and humidity through manual monitoring. There are problems such as large temperature fluctuations, inaccurate humidity control, and cumbersome operations, which easily lead to uneven seed water absorption and a high risk of mildew, and it is difficult to meet the requirements of large-scale planting for germination efficiency and consistency.
[0003] In the prior art, some seed soaking devices use a single electric heating tube for heating or a thermoelectric cooler for cooling, and cannot achieve dynamic two-way adjustment in the range of 25-30 °C. Moreover, there is a lack of a circulating water flow design, which easily causes local uneven heating and cooling; humidity control mostly relies on intermittent spraying or static water immersion, and the accuracy of humidity sensors is insufficient (error > ±5%RH), which easily leads to water accumulation or mold growth. In addition, traditional devices rely on manual timing for water change and parameter adjustment, with low automation and high energy consumption, and it is difficult to adapt to the batch production requirements of different capacities.
[0004] Based on the above defects, designing a seed soaking device integrating intelligent temperature control, humidity closed-loop regulation, and automatic circulating water flow, through the coordinated control of high-precision sensors and a microcomputer, to achieve precise and stable temperature and humidity, antibacterial and mildew-proof, and low-energy consumption operation, and support multi-capacity expansion and unmanned operation, has become a key requirement for improving the germination rate of cotton seeds and agricultural production efficiency.

[0032] 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.
[0033] As Figures 1-8 , an intelligent temperature-controlled seed soaking device for improving the germination rate of cotton seeds, comprising a seed soaking container 1, cotton seeds are placed in the seed soaking container 1 for seed soaking, and a humidity control system 5, a temperature control system 6 and a circulating water flow system 7 are arranged on the seed soaking container 1;
[0034] A microcomputer control panel 4 is arranged on the outer side of the seed soaking container 1, and the user can set the temperature of the seed soaking container 1 (default 25 - 30 °C) and the working mode through the touch screen or buttons.
[0035] The humidity control system 5 is used to maintain the air humidity inside the seed soaking container 1, promote the seeds to absorb water and expand, and can also prevent the growth of mildew. The humidity control system includes a humidifying device 51 installed on the top of the seed soaking container 1, a ventilation hole is opened at the top of the seed soaking container 1 and below the humidifying device 51, and a dust-proof net 52 is installed in the ventilation hole;
[0036] The humidifying device 51 is an ultrasonic humidifier: when the humidity is lower than the set value, water is supplemented through the ultrasonic humidifier to keep the environment humid and promote the seeds to absorb water and expand.
[0037] The ventilation hole with a dust-proof net 52 at the top of the seed soaking container 1 can ensure appropriate air circulation and prevent the growth of mildew.
[0038] The temperature control system 6 integrates heating and cooling functions. It monitors the water temperature through built-in sensors and automatically adjusts it to the optimal temperature suitable for cotton seed germination (usually 25 - 30 °C). The temperature control system 6 includes a heating chamber 62 formed by partitioning inside the soaking container 1. The space above the partition is used for soaking cotton seeds. Inside the heating chamber 62, there is a PTC ceramic heating element 63. A heat conduction tube 64 is fixedly connected to the PTC ceramic heating element 63. One end of the heat conduction tube 64 passes through the outside of the soaking container 1 and extends from the top of the soaking container 1 to the inside of the soaking container 1. At the top of the inner wall of the soaking container 1, there is a radiator 65 fixedly connected. The heat conduction tube 64 and the radiator 65 are fixedly connected. The PTC ceramic heating element 63 heats the water flow inside the heat conduction tube 64, and the heat is conducted to the inside of the soaking container 1 where the radiator 65 is located through the heat conduction tube 64 and the radiator 65, so as to regulate the temperature inside the soaking container 1.
[0039] Such as Figure 1 and Figure 2 , the soaking container 1 is made of corrosion-resistant food-grade stainless steel or polypropylene material to ensure safety and non-toxicity during seed soaking. The capacity of the soaking container 1 is designed with different capacity specifications according to actual needs (such as 5L, 10L, 20L, etc.), which is suitable for different scales of agricultural production.
[0040] Such as Figure 1 , the bottom of the soaking container 1 is fixedly connected with support legs 3, and universal wheels 2 are installed at the bottom of the support legs 3. Two of the universal wheels 2 are universal wheels with locking functions in the prior art, which facilitates the movement and fixing of the equipment.
[0041] Such as Figure 2 and Figure 3 , the circulating water flow system 7 can ensure the uniformity of the water quality in the container and avoid local overheating or cold spots affecting seed germination. The circulating water flow system 7 includes a water pump 72. The water pump 72 uses a low-noise DC pump with a moderate power to ensure uniform water flow distribution without damaging the seeds. The water pump 72 is installed inside the soaking container 1, and a water inlet pipe 71 is fixedly installed at the water inlet of the water pump 72. One end of the water inlet pipe 71 extends to the outside of the soaking container 1.
[0042] Such as Figure 2 and Figure 3 , the water outlet of the water pump 72 is fixedly connected with a spray pipe 73. A plurality of nozzles are evenly arranged on the spray pipe 73. Warm water is sprayed through the nozzles to form a gentle water flow circulation, avoiding local overheating or cold spots.
[0043] Such as Figure 3 、 Figure 5 and Figure 7, on the outer surface of the water inlet pipe 71 and inside the seed soaking container 1, there is a fixedly connected assembly shell 75. Inside the assembly shell 75, a T-shaped filter net 74 is fixedly installed. Filter holes 76 are formed on the T-shaped filter net 74. The T-shaped filter net 74 is arranged at the water inlet to prevent impurities from entering the circulation system and facilitate cleaning and maintenance.
[0044] As Figure 2 and Figure 5 , a drainage unit 8 is arranged on the seed soaking container 1. The drainage unit includes a base 83 fixed on the outer side of the seed soaking container 1. A drainage hole 81 is opened on the seed soaking container 1. A drainage valve 82 is installed above the base 83 on the outside of the drainage hole 81. By opening the drainage valve 82, the water quality can be changed or the container can be cleaned.
[0045] As Figure 3 , Figure 4 and Figure 8 , a cooling unit 9 is arranged on the seed soaking container 1. The cooling unit 9 can assist in cooling and maintain a suitable temperature range. The cooling unit 9 includes a fan frame 91 fixed on the top of the seed soaking container 1. A motor 93 is installed on the fan frame 91. The motor 93 is externally powered and can be controlled through the microcomputer control panel 4. The output end of the motor 93 is fixedly connected with a fan blade 94. A heat sink 92 is fixedly connected below the fan blade 94 on the fan frame 91;
[0046] On the top of the seed soaking container 1 and on one side of the fan frame 91, a refrigeration chip 96 is installed. The refrigeration chip 96 is a prior art. A heat exchange copper tube 95 is installed on one side of the refrigeration chip 96. The heat exchange copper tube 95 is connected to the heat sink 92 and can cool the heat sink 92 to improve the heat dissipation effect of the heat sink 92.
[0047] There is an opening below the cooling unit 9 at the top of the seed soaking container 1, so that the motor 93 drives the fan blade 94 to rotate, and the air flow is blown into the interior of the seed soaking container 1, which can assist in cooling the cotton seeds in the seed soaking container 1. The air flow passes through the heat sink 92, and the heat sink 92 can play a role in reducing the temperature of the air flow.
[0048] As Figure 1 , Figure 3 and Figure 5 , a timer, an alarm lamp 101 and a temperature and humidity sensor 102 are installed inside the seed soaking container 1. The timer, the alarm lamp 101 and the temperature and humidity sensor 102 are all prior arts and will not be elaborated here. A transparent observation window 103 that can be opened and closed is arranged on the outside of the seed soaking container 1.
[0049] Set the optimal soaking time (such as 8 - 12 hours). When the preset time is reached, the timer and the alarm lamp 101 will emit an alarm to remind the operator. The temperature and humidity sensor 102 monitors the temperature and humidity inside the container. The transparent observation window 103 can monitor the seed state in real time. There is a gasket between the transparent observation window 103 and the soaking container 1, which can ensure the sealing performance between the transparent observation window 103 and the soaking container 1.
[0050] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
