[0002] Before rice is planted, it is necessary to soak the rice seeds. The soaking process is the process of the seeds absorbing water. After the seeds absorb water, the activity of the seed enzyme begins to rise.

The first temperature sensor and humidity sensor are installed on either the front or back side of the inner cavity of the shell 1, and the fan 10, the first temperature sensor, and the humidity sensor are all electrically connected to the PLC controller.

[0036] Specifically, the fans 10 symmetrically arranged on the left and right sides of the inner cavity of the shell 1 can be used to blow out convection wind to improve the air flow in the inner cavity of the shell 1, which not only accelerates the heating rate inside the shell 1, but also ensures the uniformity of temperature distribution, thereby ensuring the consistency of the germination state of rice seeds.

[0037] Specifically, the first temperature sensor is used to monitor the air temperature in the inner cavity of the shell 1 in real time; the humidity sensor is used to monitor the air humidity in the inner cavity of the shell 1 in real time.

[0038] Specifically, when the first temperature sensor detects that the temperature in the inner cavity of the shell 1 is lower than the preset temperature, the PLC controller controls the first heating plate 6 to start working and heat the air in the shell 1 until the temperature in the inner cavity of the shell 1 reaches the preset temperature and then stops working, so that the air temperature in the inner cavity of the shell 1 reaches a dynamic balance.

[0039] Specifically, when the rice seeds are in the germination operation, if the humidity sensor detects that the humidity in the inner cavity of the shell 1 is lower than the preset humidity, the PLC controller controls the second heating plate 203 to start working, and heats the soaking water in the water storage tank body 201 to generate water vapor to increase the humidity in the inner cavity of the shell 1, and stops working after the humidity in the inner cavity of the shell 1 reaches the preset humidity, so that the air humidity in the inner cavity of the shell 1 reaches a dynamic balance.

[0040] Specifically, the water tank assembly 2 includes a water tank body 201, support legs 202, a second heating plate 203, a water inlet pipe 204 and a water outlet pipe 205. The four support legs 202 are respectively arranged at the four corners of the bottom of the water tank body 201. The water tank body 201 is fixedly connected to the bottom of the inner cavity of the shell 1 through the support legs 202. The second heating plate 203 is installed at the bottom of the water tank body 201. The water inlet pipe 204 and the water outlet pipe 205 are respectively arranged on the left and right sides of the water tank body 201, and one end of the water inlet pipe 204 and the water outlet pipe 205 are both connected to the water tank body 201, and the other ends of the water inlet pipe 204 and the water outlet pipe 205 pass through the cavity wall of the shell 1 and extend outward. The second heating plate 203 is electrically connected to the PLC controller.

[0041] Specifically, the water tank assembly 2 further includes a second temperature sensor, which is disposed inside the water tank body 201 and is used to measure the water temperature inside the water tank body 201 , and the second temperature sensor is electrically connected to the PLC controller.

[0042] Specifically, the second temperature sensor is used to monitor the temperature of the soaking water in the water storage tank body 201 in real time.

[0043] Specifically, when the second temperature sensor detects that the temperature of the soaking water in the water storage tank body 201 is lower than the preset temperature, the PLC controller controls the second heating plate 203 to start working, and the second heating plate 203 stops working after the temperature of the soaking water reaches the preset temperature, so that the temperature of the soaking water in the water storage tank body 201 reaches a dynamic balance.

[0044] Specifically, the driving assembly 5 includes a driving motor 501 and a reciprocating screw rod 502. The two driving motors 501 are installed on the left and right sides of the bottom of the inner cavity of the shell 1. One end of the reciprocating screw rod 502 is connected to the power output end of the driving motor 501 through a coupling, and the other end of the reciprocating screw rod 502 is rotatably connected to the connecting block 101 set on the side wall of the shell 1.

[0045] Specifically, the seed soaking tank assembly 3 includes a seed soaking tank body 301, a partition 302, a first sponge block 303, a supporting plate 304 and a spring 305. The connecting ears on both sides of the seed soaking tank body 301 are threadedly connected to the reciprocating screw rod 502. A plurality of partitions 302 are horizontally arranged in the seed soaking tank body 301, and divide the inner cavity of the seed soaking tank body 301 into a plurality of seed soaking cavities 306. The supporting plate 304 is slidably connected in the seed soaking cavity 306. The spring 305 is installed at the bottom of the seed soaking cavity 306, and the two ends of the spring 305 are fixedly connected to the supporting plate 304 and the opposite surfaces of the bottom of the seed soaking cavity 306, respectively. The first sponge block 303 is adhesively connected to the top of the supporting plate 304.

[0046] Specifically, the bottom plate and the supporting plate 304 of the seed soaking tank body 301 are both configured as mesh structures; and the partition plate 302 is provided with limiting holes 307 for positioning the seed soaking bag.

[0047] Specifically, different types of rice seeds are placed in corresponding seed soaking bags respectively, and these seed soaking bags are connected in series in sequence with needle and thread to facilitate subsequent unified disinfection and cleaning. After completing the above operations, the user needs to place these seed soaking bags one by one into the seed soaking cavity 306, and position the rope connecting the two seed soaking bags in the limiting hole 307 opened on the partition 302, which can effectively prevent the rope from getting knotted or entangled during the seed soaking process.

[0048] Specifically, in order to facilitate the user to track and record the soaking and germination conditions of rice seeds in different soaking cavities 306, marking numbers can be pre-engraved on the side wall of the soaking tank body 301 corresponding to the position of each soaking cavity 306 to assist the user to accurately record and monitor the growth of seeds in each area.

[0049] Specifically, the setting of the supporting plate 304 can form a space sandwich at the bottom of the seed soaking tank body 301, which can provide more oxygen for the rice seeds in moisturizing and germinating. In addition, the setting of the spring 305 can give the supporting plate 304 a certain elastic stroke, so that the first sponge block 303 and the second sponge block 403 can wrap the rice seeds more tightly.

[0050] Specifically, the moisture lock component 4 includes a water tank 401, a nozzle 402, a second sponge block 403, a pressure sensor 404, an electric flow control valve 405 and a liquid level sensor. The water tank 401 is fixedly connected to the bottom of the end cover 7, and a plurality of nozzles 402 are arranged at equal intervals below the water tank 401. The nozzles 402 are connected to the water tank 401 through a water pipe 407. The electric flow control valve 405 is installed on the water pipe 407 and is used to control the water level of the water pipe 407. The second sponge block 403 is fixedly connected to the water spraying end of the nozzle 402, and the number and position of the second sponge block 403 match the seed soaking cavity 306. The pressure sensor 404 is installed at the bottom of the connecting block 101 and is used to contact the top of the connecting ear of the seed soaking tank body 301. The liquid level sensor is installed in the water tank 401. The pressure sensor 404, the electric flow control valve 405 and the liquid level sensor are all electrically connected to the PLC controller.

[0051] Specifically, a liquid adding pipe 406 is provided on the top of the end cover 7 , and the liquid adding pipe 406 is connected to the water storage tank 401 .

[0052] Specifically, when the rice seeds reach the preset soaking time, the driving motor 501 and the reciprocating screw rod 502 work together to drive the seed soaking tank body 301 to move upward, so that the rice seeds in the seed soaking cavity 306 are away from the water storage tank body 201. When the seed soaking tank body 301 rises to the highest point, the second sponge block 403 fits tightly to the top of the rice seeds, and forms an upper and lower wrapping with the first sponge block 303 at the bottom, effectively locking the moisture of the seeds; at the same time, the top of the connecting ear on one side of the seed soaking tank body 301 contacts the working end of the pressure sensor 404 installed at the bottom of the connecting block 101. After receiving the electrical signal from the pressure sensor 404, the PLC controller controls the electric flow control valve 405 to open. At this time, the water or nutrient solution stored in the water storage tank 401 will pass through the water pipe 407, the electric flow control valve 405 and the nozzle 402 in turn to transport the moisture to the second sponge block 403, providing sufficient moisture for the germination of the seeds.

[0053] Specifically, the user can pre-set the opening and closing interval duration of the electric flow control valve 405 and the flow rate of the delivered liquid through the display screen 8 and the adjustment button 9.

[0054] Specifically, the provision of the liquid level sensor allows the user to promptly learn the remaining amount of water stored in the water tank 401 .

[0055] Specifically, the user can add water to the water tank 401 through the liquid adding pipe 406, and the water in the water tank 401 flows into the second sponge block 403 through the pipeline and the nozzle 402 in turn, so that the second sponge block 403 remains moist to assist the germination of rice seeds.

[0056] Specifically, when the rice seeds have completed soaking and enter the germination operation, the PLC controller controls the second heating plate 203 to continue heating the soaking water in the water storage tank body 201 to generate high-temperature steam, while ensuring the air humidity in the inner cavity of the shell 1 and assisting in raising the air temperature in the inner cavity of the shell 1.

[0057] The use process of the present invention is as follows:

[0058] First, open the end cover 7, and place a plurality of seed soaking bags connected in series by ropes in the seed soaking cavity 306 in order. After the seed soaking bags are placed, close the end cover 7. At this time, the second sponge block 403 fits with the top of the seed soaking bag placed in the seed soaking cavity 306.

[0059] Next, the driving motor 501 starts to work, and the seed soaking tank body 301 moves downward under the drive of the reciprocating screw rod 502 until the bottom of the seed soaking tank body 301 fits with the bottom of the water storage tank body 201, and the driving motor 501 stops working, and the soaking operation of the rice seeds starts;

[0060] Finally, when the rice seeds have reached the preset soaking time, the driving motor 501 starts working again, and drives the seed soaking tank body 301 to slide upward through the reciprocating screw rod 502 until the top of the seed soaking bag placed in the seed soaking cavity 306 fits with the bottom of the second sponge block 403, and the driving motor 501 stops working and starts the germination operation of the rice seeds; at this time, the pressure sensor 404 generates an electrical signal and controls the electric flow control valve 405 to open, providing sufficient moisture for the second sponge block 403.
