[0002] Corn is one of the most widely cultivated crops in the world. As one of the three major food crops, it is known as a "golden" industry due to its abundant yield and high utilization value. Corn seeds are generally treated to improve germination rates. However, current corn seed treatment methods mostly rely on single physical or chemical means (such as hot water soaking or gibberellin soaking), which have the following drawbacks:

[0003] 1. In existing corn seed treatment processes, the washing, soaking, and air-drying steps are performed separately. The seeds are first washed, then transferred to a chemical tank for soaking, and after twelve hours, removed for air-drying. These steps are fragmented and cannot be automated, resulting in unsatisfactory automation and convenience. 2. The soaking process lacks adjustment functions to address situations where CO2 concentration is too high or oxygen concentration is insufficient. Therefore, this application proposes a corn seed activation device to improve germination rate and solve the aforementioned problems. Utility Model Content

[0026] Specifically, the water-filtering and seed-carrying assembly includes a box-shaped stainless steel filter screen 202 movably fitted inside the treatment box 1. Two connecting rods 201 are fixedly connected to the bottom of the cover plate 2 on both sides of the top of the box-shaped stainless steel filter screen 202. The box-shaped stainless steel filter screen 202 and the connecting rods 201 work together to filter out water when carrying and washing corn seeds, and to filter out the medicine when soaking. The connecting rods 201 are used to move the box-shaped stainless steel filter screen 202 upward when the cover plate 2 is lifted and opened, so that personnel can take and put the corn seeds.

[0027] Furthermore, the water-pharmacy-gas expansion and contraction conversion supply assembly includes a water pump 402 fixedly installed at the bottom of the treatment tank 1. A second solenoid valve 4 is fixedly connected to the bottom of both the medicine tank 102 and the clean water tank 101 on their adjacent sides. A three-way pipe 401 is fixedly connected between the adjacent ends of the two second solenoid valves 4. The top end of the three-way pipe 401 is fixedly connected to the inlet of the water pump 402. An air pump 403 is fixedly installed on the top of the cover plate 2. A one-way valve 4 is fixedly connected to both the air outlet of the air pump 403 and the water outlet of the water pump 402. 04. The two one-way valves 404 are both outlets at their closest ends. The top of the lower one-way valve 404 extends into the processing box 1 and is connected to and fixed with a telescopic hose 407. A vertical pipe 405 is connected and fixed between the top of the telescopic hose 407 and the bottom of the upper one-way valve 404. Multiple spray holes 406 are opened on all four sides of the vertical pipe 405. A box-shaped stainless steel filter screen 202 is fixedly sleeved on the vertical pipe 405. The air pump 403, water pump 402 and the second solenoid valve 4 are all electrically connected to the PLC controller 3.

[0028] The system is configured with a second solenoid valve 4, a three-way pipe 401, an air pump 403, a check valve 404, a telescopic hose 407, a vertical pipe 405, and a spray nozzle 406. The PLC controller 3 is pre-set to control the opening and closing times of the left-side second solenoid valve 4, the drain solenoid valve 104, the first solenoid valve 103, the water pump 402, the air pump 403, and the right-side second solenoid valve 4. Based on the five-minute washing and twelve-hour soaking required for corn seed activation, the start time of the right-side second solenoid valve 4 is set ten minutes after the start time of the left-side second solenoid valve 4. The start-to-close interval for both second solenoid valves 4 is five minutes. The drain solenoid valve 104 opens simultaneously with the left-side second solenoid valve 4. The interval between closing and opening is ten minutes. The water pump 402 is programmed to open in three stages, with the first two opening and closing times coinciding with the opening and closing times of the two second solenoid valves 4. The first solenoid valve 103 is programmed to open for twenty minutes, twelve hours after the second closing of the water pump 402. After the first solenoid valve 103 opens for twenty minutes, it controls the water pump 402 to open for five minutes, the left-side second solenoid valve 4 to open for five minutes, and the drain solenoid valve 104 to open for ten minutes. The drain solenoid valve 104 is also programmed to open for ten minutes before controlling the air pump 403 to open. During processing, the PLC controller 3 first controls the left-side second solenoid valve 4 to open for five minutes, the water pump 402 to open for five minutes, and the drain solenoid valve 104 to open for ten minutes. At this time, the water pump 402 first passes through the three-way pipe sequentially. 401 and the second solenoid valve 4 on the left draw clean water from the clean water tank 101, and pump it sequentially through the one-way valve 404 and the telescopic hose 407 into the vertical pipe 405. The clean water is sprayed out through multiple nozzles 406 into the corn seeds for cleaning. The cleaning water is discharged through the drain solenoid valve 104. Personnel can connect the outlet of the drain solenoid valve 104 to the designated external discharge location through an external hose. After five minutes, the PLC controller 3 first controls the water pump 402 and the second solenoid valve 4 on the left to close, waiting for the water to be fully discharged through the drain solenoid valve 104. After ten minutes, the PLC controller 3 controls the drain solenoid valve 104 to close again, and controls the second solenoid valve 4 on the right and the water pump 402 to open. At this time, the water pump 402 is switched to drawing water from the medicine tank 101. The solution in tank 02 is supplied to the vertical pipe 405, and then sprayed out through multiple nozzles 406 into the treatment tank 1. After five minutes, the treatment tank gradually fills with solution. At this time, the PLC controller 3 controls the water pump 402 and the second solenoid valve 4 on the right to close. The solution then soaks and activates the corn seeds. After twelve hours, the PLC controller 3 controls the first solenoid valve 103 to open for twenty minutes. The solution then flows back to the solution tank 102 through the first solenoid valve 103 for reuse. After twenty minutes, the PLC controller 3 controls the water pump 402, the second solenoid valve 4 on the left, and the drain solenoid valve 104 to open for five minutes, five minutes, and ten minutes respectively to wash the soaked corn seeds again. Finally, the PLC controller 3 controls the air pump 403 to start.At this time, the air pump 403 draws in external gas and supplies it into the vertical pipe 405 through the one-way valve 404 above. The gas is then blown out from the inside through multiple nozzles 406 into the corn seeds for air drying, achieving an integrated automatic process of cleaning, soaking and activating, cleaning again, and air drying the corn seeds.

[0029] Furthermore, the temperature measuring and heating assembly includes an electric heater 501 and a temperature sensor 5, which are fixedly installed at the bottom right side of the treatment box 1 and electrically connected to the PLC controller 3. The detection end of the temperature sensor 5 and the heating end of the electric heater 501 both extend into the treatment box 1. The temperature sensor 5 and the electric heater 501 are both located below the box-shaped stainless steel filter screen 202. The electric heater 501 and the temperature sensor 5 work together to control the temperature value of the electric heater 501 to turn on and off within the soaking time period by using the PLC controller 3 to preset the temperature value. According to the temperature value required for the soaking and activation of corn seeds, which is between 20 and 30 degrees Celsius, the on value is set to 25 degrees Celsius and the off value is set to 26 degrees Celsius. The temperature sensor 5 detects the temperature of the chemical solution in the treatment box 1 and transmits the temperature value to the PLC controller 3. When the temperature value is lower than the preset value, the PLC controller 3 controls the electric heater 501 to turn on to heat the chemical solution. When the temperature value reaches the preset value, the PLC controller 3 controls the electric heater 501 to turn off, thereby achieving the effect of automatic temperature control and heating of the chemical solution to provide favorable conditions for the activation of corn seeds.

[0030] Furthermore, a humidity sensor, a carbon dioxide concentration sensor, and an oxygen concentration sensor 302 electrically connected to the PLC controller 3 are fixedly installed at the bottom of the cover plate 2, and an exhaust hole is provided on the top left side of the cover plate 2. The humidity sensor, carbon dioxide concentration sensor, and oxygen concentration sensor 302 are used to monitor the carbon dioxide concentration and oxygen concentration in the treatment tank 1 during the soaking process, and to monitor the humidity in the treatment tank 1 during the air drying process. The PLC controller 3 is used to preset the humidity value that controls the air pump 403 to shut off during the air drying process. When the preset humidity value is reached, the PLC controller 3 controls the air pump 403 to shut off automatically. The PLC controller 3 is also used to preset the carbon dioxide concentration and oxygen concentration values ​​that control the air pump 403 to turn on and off during the soaking period. When the carbon dioxide concentration is higher than the preset value or the oxygen concentration is lower than the preset value, the PLC controller 3 will also control the air pump 403 to turn on to draw in external gas and supply it into the solution. By utilizing the principle that external air contains oxygen, oxygen is added to the solution until the carbon dioxide concentration and oxygen concentration both reach the set value range.

[0031] The usage method of this embodiment is as follows: When using the corn seed activation device to improve germination rate, the operator first controls the two multi-stage electric telescopic rods 203 to start forward through the PLC controller 3, driving the cover plate 2 to move upward and open. The cover plate 2 drives the box-shaped stainless steel filter screen 202 to move upward through the connecting rod 201. The box-shaped stainless steel filter screen 202 drives the vertical tube 405 to stretch the telescopic hose 407. At this time, the operator puts the corn seeds to be processed into the box-shaped stainless steel filter screen 202. Then, the operator controls the multi-stage electric telescopic rods 203 to start in reverse, driving the cover plate 2 to close downward. The cover plate 2 drives the box-shaped stainless steel filter screen 202 to move into the processing box 1 through the connecting rod 201.

[0032] The PLC controller 3 is pre-programmed to control the opening and closing times of the second solenoid valve 4 on the left, the drain solenoid valve 104, the first solenoid valve 103, the water pump 402, the air pump 403, and the second solenoid valve 4 on the right. Based on the corn seed activation treatment requiring five minutes of washing and twelve hours of soaking, the start time of the second solenoid valve 4 on the right is set ten minutes after the start time of the second solenoid valve 4 on the left. The start-to-close interval for both second solenoid valves 4 is five minutes. The drain solenoid valve 104 opens simultaneously with the second solenoid valve 4 on the left, with a ten-minute start-to-close interval. The water pump 402 is programmed to open three times, with the first two opening times corresponding to the opening and closing times of the two solenoid valves 403. The opening and closing times of the two solenoid valves 4 are the same. The first solenoid valve 103 is set to open for 20 minutes 12 hours after the second closure of the water pump 402. The first solenoid valve 103 is set to open for 20 minutes, and the water pump 402, the second solenoid valve 4 on the left side, and the drain solenoid valve 104 are set to open for 10 minutes after the first solenoid valve 103 is opened for 20 minutes. The air pump 403 is set to open after the drain solenoid valve 104 is opened for 10 minutes. In addition, the PLC controller 3 is used to preset the temperature value for controlling the opening and closing of the electric heater 501 during the soaking time period. According to the existing temperature value required for the soaking and activation of corn seeds, which is between 20 and 30 degrees Celsius, the opening value is set to 25 degrees Celsius and the closing value is set to 26 degrees Celsius.

[0033] After the operator starts the pre-programmed processing program using PLC controller 3, PLC controller 3 first controls the second solenoid valve 4 on the left to open for five minutes, the water pump 402 to open for five minutes, and the drain solenoid valve 104 to open for ten minutes. At this time, the water pump 402 first draws clean water from the clean water tank 101 through the three-way pipe 401 and the second solenoid valve 4 on the left, and then pumps it into the vertical pipe 405 through the one-way valve 404 below and the telescopic hose 407. The clean water is sprayed out through multiple nozzles 406 into the corn seeds for cleaning. The cleaning water is discharged through the drain solenoid valve 104, and the operator drains the water. The outlet of solenoid valve 104 can be connected to a designated external discharge location via an external hose. After five minutes, PLC controller 3 first controls water pump 402 and the second solenoid valve 4 on the left to close, waiting for water to be fully discharged through drain solenoid valve 104, completing the initial cleaning. After ten minutes, PLC controller 3 controls drain solenoid valve 104 to close again, and controls the second solenoid valve 4 on the right and water pump 402 to open. At this time, water pump 402 switches to drawing chemicals from chemical tank 102 and supplying them to the vertical pipe 405. The chemicals are then sprayed out through multiple nozzles 406 into treatment tank 1. After five minutes, the treatment tank is gradually filled with chemicals. In the treatment tank, the PLC controller 3 controls the water pump 402 and the second solenoid valve 4 on the right to close, allowing the chemical solution to soak and activate the corn seeds. After twelve hours, the PLC controller 3 controls the first solenoid valve 103 to open for twenty minutes, allowing the chemical solution to flow back to the chemical tank 102 for reuse. After twenty minutes, the PLC controller 3 controls the water pump 402, the second solenoid valve 4 on the left, and the drain solenoid valve 104 to open for five minutes, five minutes, and ten minutes respectively, to wash the soaked corn seeds again, achieving a secondary cleaning and reducing chemical residues. The system detects chemical residues and then controls the PLC controller 3 to turn on the air pump 403. At this time, the air pump 403 draws external gas and supplies it into the vertical pipe 405 through the one-way valve 404 above. The gas is then blown out from the inside through multiple nozzles 406 into the corn seeds for air drying. This achieves the integrated automatic effect of cleaning, soaking and activating, cleaning again and air drying the corn seeds. By using the method of cleaning again after soaking, the phenomenon of chemical residues is reduced. Through the integrated multi-step automatic processing method, there is no need for personnel to transfer and operate between multiple steps step by step, which improves the automation and convenience of use.

[0034] In addition, during the soaking period, the temperature sensor 5 detects the temperature of the solution in the treatment tank 1 and transmits the temperature value to the PLC controller 3. When the temperature value is lower than the preset value, the PLC controller 3 controls the electric heater 501 to turn on to heat the solution. When the temperature value reaches the preset value, the PLC controller 3 controls the electric heater 501 to turn off, so as to achieve the effect of automatic temperature control and heating of the solution during the soaking process, so as to provide favorable conditions for the activation of corn seeds and thus improve their germination rate.

[0035] In addition, the PLC controller 3 is pre-set to control the air pump 403 to shut off during air drying, and to control the air pump 403 to turn on and off during the soaking period. Humidity sensor, carbon dioxide concentration sensor, and oxygen concentration sensor 302 monitor the carbon dioxide and oxygen concentrations in the treatment tank 1 during the soaking process. During the soaking period, if the carbon dioxide concentration is higher than the preset value or the oxygen concentration is lower than the preset value, the PLC controller 3 will separately control the air pump 403 to turn on, drawing external air into the vertical pipe 405, which is then sprayed into the solution through the nozzle 406, utilizing the oxygen content of the external air. The process involves oxygenating the solution until both carbon dioxide and oxygen concentrations reach the set range. During air drying, when the preset humidity value is reached, the PLC controller 3 automatically shuts off the air pump 403 to prevent it from running continuously without restraint. By automatically supplying oxygen based on the carbon dioxide or oxygen concentration during the soaking period, the system achieves automatic adjustment and assistance when the carbon dioxide concentration is too high or the oxygen concentration is insufficient, further improving the activation environment and germination rate of the corn seeds. After treatment, the multi-stage electric telescopic rod 203 is activated again to drive the box-shaped stainless steel filter 202 upwards, allowing the corn seeds to be removed.

[0036] The PLC controller 3, temperature sensor 5, electric heater 501, humidity sensor, carbon dioxide concentration sensor, oxygen concentration sensor 302, second solenoid valve 4, drain solenoid valve 104, first solenoid valve 103, water pump 402, and air pump 403 in this utility model are well known to those skilled in the art and belong to conventional means or common knowledge. Those skilled in the art can arbitrarily select and match them according to their needs or convenience. In addition, the PLC controller 3 controls the opening and closing of the second solenoid valve 4, drain solenoid valve 104, first solenoid valve 103, water pump 402, and air pump 403 according to the pre-programmed control time sequence, and controls the electric heater 501 to close accordingly according to the temperature value transmitted by the temperature sensor 5. These are all basic numerical control programming parameter setting control methods well known to those skilled in the art and belong to conventional means or common knowledge. They will not be described in detail here.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
