UTILIZABLE CONTENT

[0004] The utility model aims at solving the shortcomings in prior art, and proposes a saffron crocus seedling test cultivation device.

[0005] In order to realize the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A saffron seedling experimental cultivation device includes a cabinet. Universal wheels are installed at each of the four corners of the cabinet's bottom. Cabinet doors are rotatably connected to both ends of the cabinet's outer side wall. A sliding groove is formed on the side of the cabinet's outer side wall away from the cabinet doors. A water tank is fixed to one end of the cabinet's inner bottom, and a connecting box is fixed to the other end. The connecting box contains a temperature regulating mechanism. A culture dish is fixed to the top of the cabinet, with an inclined bottom. A partition is fixed to the inner side wall of the culture dish. A through groove is formed near the lowest point of the bottom of the culture dish, and a filter screen is fixed to the inner side wall of the through groove. A humidity sensor is fixed to the bottom of the culture dish. A transparent glass cover is installed on the top of the cabinet, with a temperature sensor fixed to the inner side wall of the transparent glass cover. Air outlets are formed on both sides of the transparent glass cover. A lifting mechanism for raising and lowering the transparent glass cover is installed on the top of the cabinet. A first connecting pipe is installed inside the transparent glass cover, and multiple... The device includes a nozzle, a water delivery mechanism inside the cabinet for supplying water to the first connecting pipe, a moving mechanism inside the transparent glass cover for moving the first connecting pipe, and a filtration mechanism on top of the water tank for filtering water. During use, a humidity sensor detects soil moisture and, in conjunction with the water delivery mechanism, supplies water to the first connecting pipe. Simultaneously, the moving mechanism drives the first connecting pipe to move back and forth, evenly spraying water onto the soil surface. Excess water is filtered by the filtration mechanism and recycled into the water tank. This eliminates the need for manual watering, improving work efficiency and ensuring even and appropriate watering each time, preventing over- or under-watering. The recycling of excess water also saves water resources. A temperature sensor, in conjunction with an adjustment mechanism, monitors and controls the temperature inside the transparent glass cover, ensuring the necessary growth conditions for the saffron seedlings and improving the quality of the saffron.

[0007] As a further embodiment of this utility model, the lifting mechanism includes two support plates, which are respectively fixed at opposite corners of the outer wall of the transparent glass cover. Two hydraulic push rods are fixed to the top of the cabinet, and the output ends of the two hydraulic push rods are respectively fixed to the two support plates.

[0008] As a further embodiment of this utility model, the water delivery mechanism includes a water pump, which is fixed to the bottom of the cabinet and its inlet is connected to a water tank. A second flexible hose is fixed to the outlet of the water pump, and the second flexible hose is slidably disposed on the side wall of the slide groove and is connected to a first connecting pipe. The moving mechanism includes a slide rod, which is fixed to the inner wall of a transparent glass cover. A reciprocating screw is rotatably connected to the inner wall of the transparent glass cover, and the reciprocating screw and the slide rod are arranged in parallel. The slide rod and the reciprocating screw are fitted with sidewall sleeves. A single lead screw and slider are provided. A pin hole is radially arranged on the inner circumference of the lead screw and slider. A crescent pin that mates with a reciprocating lead screw is placed inside the pin hole. The lead screw and slider are fixed to a first connecting pipe. A motor is fixed to the outer wall of one end of the transparent glass cover, and the motor's output shaft is fixed to the reciprocating lead screw. The filter mechanism includes a receiving box, which is fixed to the top end of the cabinet and communicates with a through groove. A filter layer is fixed to the inner wall of the receiving box. Multiple water outlet pipes are fixed at equal intervals at the bottom of the receiving box. All water outlet pipes are connected to the water tank. Since the humidity sensor and temperature sensor are electrically connected to a controller, when the soil humidity is not up to standard, the humidity sensor generates a signal and transmits it to the controller. After receiving the signal, the controller turns on the power switches of the water pump and motor. After the water pump is powered on, it works with the second hose to draw clean water from the water tank into the first connecting pipe and spray it out through multiple nozzles. At the same time, the drive motor drives the reciprocating screw to rotate, which in turn drives the screw slider to move, thereby moving the first connecting pipe back and forth along the top of the petri dish. This can evenly spray clean water onto the surface of the soil until the soil humidity reaches the experimental standard. Excess water is initially filtered through a filter screen and then enters the receiving box for secondary filtration through a filter layer. Finally, it enters the water tank through multiple water outlet pipes for recycling. During the process, no manual watering is required, which not only improves work efficiency but also ensures the uniformity and suitability of each watering, avoiding excessive or insufficient watering. At the same time, excess water can be recycled and reused, saving water resources.

[0009] As a further embodiment of this utility model, the adjusting mechanism includes a thermoelectric cooler, which is fixed to the inner wall of the connecting box. Multiple first fins are fixed at equal intervals on the cold end of the thermoelectric cooler, and multiple second fins are fixed at equal intervals on the hot end of the thermoelectric cooler. A fan is fixed to the bottom of the cabinet, and a three-way pipe is fixed to the air outlet of the fan. Both ends of the three-way pipe are connected to the connecting box, and both ends are symmetrically distributed about the thermoelectric cooler. A third solenoid valve and a fourth solenoid valve are respectively installed at both ends of the three-way pipe. A second connecting pipe is installed through the outer wall of the connecting box, and both ends of the second connecting pipe are symmetrically distributed about the thermoelectric cooler. A first solenoid valve and a second solenoid valve are respectively installed at both ends of the second connecting pipe. A first flexible hose is fixed to the side wall of the second connecting pipe, and both ends of the first flexible hose are connected to the second connecting pipe and a transparent glass cover. When the temperature inside the transparent glass cover is too high or too low, the temperature sensor will generate a signal and transmit it to the controller. After receiving the signal, the controller will turn on the fan and the thermoelectric cooler. The power switch for the thermoelectric cooler causes the cold end temperature to drop rapidly when energized, resulting in a rapid decrease in the surface temperature of the multiple first fins. Simultaneously, the hot end temperature rises, causing a rapid increase in the surface temperature of the multiple second fins. When the transparent glass cover temperature becomes too high, the third and second solenoid valves close, while the fourth and first solenoid valves open. This drives a fan to draw outside air into the connecting box through a three-way pipe and the fourth solenoid valve. At this point, the air contacts the surfaces of the multiple first fins, lowering their temperature. The cold air then enters the transparent glass cover through the first solenoid valve and the first flexible hose, heating the interior. When the temperature inside the transparent glass cover becomes too low, the fourth and first solenoid valves close, while the third and second solenoid valves open. The air drawn in by the fan then contacts the surfaces of the multiple second fins, heating them. The hot air then enters the transparent glass cover through the second solenoid valve and the first flexible hose, further raising the temperature. This controls the temperature inside the transparent glass cover to be between a hydraulic push rod temperature and a filter temperature, thereby improving the growth and development of saffron.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. During use, this device detects soil moisture using a humidity sensor and, in conjunction with a water delivery mechanism, delivers water to the inside of the first connecting pipe. Simultaneously, a moving mechanism drives the first connecting pipe to move back and forth, evenly spraying water onto the soil surface. Excess water is filtered through a filtration mechanism and then recycled into a water tank. The process eliminates the need for manual watering, improving work efficiency and ensuring the uniformity and suitability of each watering, preventing excessive or insufficient watering. Furthermore, the recycling of excess water conserves water resources.

[0012] 2. By using a temperature sensor in conjunction with an adjustment mechanism, the temperature inside the transparent glass cover can be monitored and controlled, ensuring the necessary growth conditions for the saffron seedlings and improving the quality of the saffron.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1 - Figure 7A saffron seedling experimental cultivation device includes a cabinet 1, with casters 3 installed at all four corners of the bottom of the cabinet 1. Cabinet doors 2 are symmetrically connected to both ends of the outer wall of the cabinet 1. A sliding groove 11 is provided on the side of the outer wall of the cabinet 1 away from the cabinet door 2. A water tank 13 is fixed to one end of the bottom of the cabinet 1, and a connecting box 18 is fixed to the other end of the bottom of the cabinet 1. The connecting box 18 is equipped with a temperature regulating mechanism to control and regulate the temperature of the cultivation environment, ensuring a suitable temperature for saffron growth. A cultivation dish 12 is fixed to the top of the cabinet 1, and the bottom of the cultivation dish 12 has an inclined structure. A partition 37 is fixed to the inner side wall of the cultivation dish 12. The cultivation dish 12 is the main container for planting saffron seedlings. The cultivation dish 12 has a sloping bottom to facilitate drainage and prevent waterlogging at the roots. The inner wall partition 37 separates different planting areas for easy management and cultivation of multiple saffron seedlings. A groove is provided at the bottom of the cultivation dish 12 near its lowest point, and a filter screen 25 is fixed to the inner wall of the groove. The filter screen 25, located within the groove of the cultivation dish 12, primarily filters excess water to prevent impurities from entering the water tank 13, thus ensuring water cleanliness and facilitating subsequent water recycling. A humidity sensor 35 is fixed to the bottom of the cultivation dish 12 to monitor the soil moisture in real time. A transparent glass cover 10 is installed on the top of the cabinet 1 to cover the cultivation dish 12, creating a closed growing environment. This system not only protects seedlings from external environmental influences but also maintains internal temperature and humidity, creating suitable growing conditions. Furthermore, the transparent design allows light to pass through, promoting photosynthesis. A temperature sensor 36 is fixed to the inner wall of the transparent glass cover 10 to monitor the temperature inside and adjust the internal environment to ensure the saffron grows under optimal temperature conditions. Air vents 6 are symmetrically located on both sides of the transparent glass cover 10. A lifting mechanism for raising and lowering the transparent glass cover 10 is installed at the top of the cabinet 1. A first connecting pipe 23 is installed inside the transparent glass cover 10, and multiple nozzles 24 are evenly spaced on the side wall of the first connecting pipe 23. A water supply system is installed inside the cabinet 1 to supply water to the inside of the first connecting pipe 23. The device includes a transparent glass cover 10 housing a moving mechanism for moving the first connecting pipe 23, and a water tank 13 topped with a filtration mechanism for filtering water. During operation, a humidity sensor 35 detects soil moisture and, in conjunction with a water delivery mechanism, delivers water to the first connecting pipe 23. Simultaneously, the moving mechanism drives the first connecting pipe 23 to reciprocate, evenly spraying water onto the soil surface. Excess water is filtered by the filtration mechanism and then recycled back into the water tank 13. This eliminates the need for manual watering, improving efficiency and ensuring even and appropriate watering each time, preventing over- or under-watering. Furthermore, it allows for the recycling of excess water.This method saves water resources. Through temperature sensor 36 and adjustment mechanism, the temperature inside the transparent glass cover 10 can be monitored and controlled, ensuring the necessary growth conditions for the saffron seedlings and improving the quality of the saffron.

[0023] In this embodiment, the lifting mechanism includes two support plates 4, which are fixed at opposite corners of the outer wall of the transparent glass cover 10. Two hydraulic push rods 5 are fixed on the top of the cabinet 1, and the output ends of the two hydraulic push rods 5 are fixed to the two support plates 4 respectively. The two hydraulic push rods 5 are driven to cooperate with the two support plates 4 to lift the transparent glass cover 10, which facilitates the planting of saffron seedlings.

[0024] In this embodiment, the water delivery mechanism includes a water pump 17, which is fixed to the bottom of the cabinet 1. The water inlet of the water pump 17 is connected to the water tank 13, and a second hose 9 is fixed to the water outlet of the water pump 17. The second hose 9 is slidably disposed on the side wall of the slide groove 11 and is connected to the first connecting pipe 23. The moving mechanism includes a slide rod 20, which is fixed to the inner side wall of the transparent glass cover 10. A reciprocating screw 21 is rotatably connected to the inner side wall of the transparent glass cover 10, and the reciprocating screw 21 and the slide rod 20 are arranged in parallel. The slide rod 20 and the reciprocating screw 21 are fitted with the same screw slider 22 on their side walls. A pin hole is provided on the inner circumferential surface of the screw slider 22 along its radial direction, and a screw is provided in the pin hole to reciprocate the screw. The rod 21 is fitted with a crescent-shaped pin, and the lead screw slider 22 and the first connecting pipe 23 are fixed together. A motor 7 is fixed to the outer wall of one end of the transparent glass cover 10, and the output shaft of the motor 7 is fixed to the reciprocating lead screw 21. The filtration mechanism includes a receiving box 15, which is located at the top of the cabinet 1 and communicates with the through groove of the petri dish 12. Its main function is to collect excess water. After preliminary filtration through the filter screen 25, the water enters the receiving box 15, which helps to recycle excess water, reduce water waste, and facilitate subsequent water recycling. The receiving box 15 is fixed to one end of the top of the cabinet 1 and communicates with the through groove. A filter layer 16 is fixed to the inner side wall of the receiving box 15. The main function of the filter layer 16 is to collect excess water. The system can further filter the water collected through the receiving box 15 to remove impurities and ensure the cleanliness of the recycled water. Multiple water outlet pipes 14 are fixed at equal intervals at the bottom of the receiving box 15, and all of these pipes are connected to the water tank 13. Since the humidity sensor 35 and temperature sensor 36 are electrically connected to a controller, when the soil humidity is insufficient, the humidity sensor 35 generates a signal that is transmitted to the controller. Upon receiving the signal, the controller turns on the power switches of the water pump 17 and motor 7. After the water pump 17 is powered on, it works with the second hose 9 to draw clean water from the water tank 13 into the first connecting pipe 23, which is then sprayed out through multiple nozzles 24. Simultaneously, the drive motor 7 drives the reciprocating screw 21. Rotation, in conjunction with the sliding rod 20 driving the lead screw slider 22 to move, thereby driving the first connecting pipe 23 to move back and forth along the top of the culture dish 12, can evenly spray clean water onto the surface of the soil until the soil moisture reaches the experimental standard. After the excess water is initially filtered through the filter screen 25, it enters the receiving box 15 and undergoes secondary filtration through the filter layer 16. Finally, it enters the water tank 13 through multiple water outlet pipes 14 for recycling. During the process, there is no need for manual watering, which not only improves work efficiency but also ensures the uniformity and suitability of each watering, avoiding excessive or insufficient water. At the same time, excess water can be recycled and reused, saving water resources.

[0025] In this embodiment, the adjustment mechanism includes a thermoelectric cooler 32, which is fixed to the inner wall of the connecting box 18. Multiple first fins 33 are fixed at equal intervals on the cold end of the thermoelectric cooler 32, and multiple second fins 34 are fixed at equal intervals on the hot end of the thermoelectric cooler 32. A fan 19 is fixed at the bottom of the cabinet 1, and a three-way pipe 29 is fixed at the outlet of the fan 19. Both ends of the three-way pipe 29 are connected to the connecting box 18, and both ends of the three-way pipe 29 are symmetrically distributed about the thermoelectric cooler 32. A third solenoid valve 30 and a fourth solenoid valve 3 are respectively installed at both ends of the three-way pipe 29. 1. A second connecting pipe 26 is provided through the outer wall of the connecting box 18, and the two ends of the second connecting pipe 26 are symmetrically distributed about the thermoelectric cooler 32. A first solenoid valve 27 and a second solenoid valve 28 are respectively provided at the two ends of the second connecting pipe 26. A first flexible hose 8 is fixed to the side wall of the second connecting pipe 26, and the two ends of the first flexible hose 8 are connected to the second connecting pipe 26 and the transparent glass cover 10 respectively. When the temperature inside the transparent glass cover 10 is too high or too low, the temperature sensor 36 will generate a signal and transmit it to the controller. After receiving the signal, the controller turns on the power switch of the fan 19 and the thermoelectric cooler 32. When the cooling chip 32 is energized, its cold end temperature drops rapidly, causing the surface temperature of the multiple first fins 33 to drop rapidly, while its hot end temperature rises, causing the surface temperature of the multiple second fins 34 to rise rapidly. When the transparent glass cover 10 becomes too hot, the third solenoid valve 30 and the second solenoid valve 28 are closed, and the fourth solenoid valve 31 and the first solenoid valve 27 are opened. The fan 19 is driven to draw in outside air through the three-way pipe 29 and the fourth solenoid valve 31 into the connecting box 18. At this time, the air comes into contact with the surfaces of the multiple first fins 33, causing their temperature to drop. The cold air then enters through the first solenoid valve 27 and the first flexible hose 8. The air is introduced into the transparent glass cover 10 and heated. When the temperature inside the transparent glass cover 10 is too low, the fourth solenoid valve 31 and the first solenoid valve 27 are closed, and the third solenoid valve 30 and the second solenoid valve 28 are opened. At this time, the air drawn in by the fan 19 comes into contact with the surface of multiple second fins 34 and is heated. The hot air enters the transparent glass cover 10 through the second solenoid valve 28 and the first hose 8 for heating. The temperature inside the transparent glass cover 10 is controlled between 5°C and 25°C, thereby improving the growth and development of saffron.

[0026] The working principle of this embodiment is as follows: During use, the device drives two hydraulic push rods 5 in conjunction with two support plates 4 to move the transparent glass cover 10 upwards, exposing the culture dish 12. The dish is pre-filled with soil, and the water tank 13 is filled with water. Multiple saffron seedlings are planted in the area divided by the partition 37. After planting, the two hydraulic push rods 5 are driven to move the transparent glass cover 10 downwards, covering the seedlings inside. Since the humidity sensor 35 and temperature sensor 36 are electrically connected to a controller, when the soil moisture is insufficient, the humidity sensor 35 generates a signal that is transmitted to the controller. Upon receiving the signal, the controller turns on the power switches of the water pump 17 and the motor 7. Once the water pump 17 is powered on... The second hose 9 draws clean water from the water tank 13 into the first connecting pipe 23, which then sprays it out through multiple nozzles 24. Simultaneously, the drive motor 7 rotates the reciprocating screw 21, which, in conjunction with the slide rod 20, moves the screw slider 22, thereby causing the first connecting pipe 23 to reciprocate along the top of the culture dish 12. This ensures the clean water is evenly sprayed onto the soil surface until the soil moisture reaches the experimental standard. Excess water is then preliminarily filtered through the filter screen 25 and enters the receiving box 15 for secondary filtration through the filter layer 16. Finally, it flows back into the water tank 13 through multiple outlet pipes 14 for recycling. This process eliminates the need for manual watering, improving work efficiency and ensuring the uniformity and suitability of each watering. To avoid excessive or insufficient moisture, and to allow for the recycling of excess water, water resources are saved. When the temperature inside the transparent glass cover 10 is too high or too low, the temperature sensor 36 will generate a signal and transmit it to the controller. After receiving the signal, the controller will turn on the power switches of the fan 19 and the thermoelectric cooler 32. When the thermoelectric cooler 32 is powered on, its cold end temperature drops rapidly, causing the surface temperature of the multiple first fins 33 to drop rapidly, while its hot end temperature rises, causing the surface temperature of the multiple second fins 34 to rise rapidly. When the temperature of the transparent glass cover 10 is too high, the third solenoid valve 30 and the second solenoid valve 28 are closed, and the fourth solenoid valve 31 and the first solenoid valve 27 are opened, driving the fan 19 to draw in outside air through the three-way pipe 2. Air is drawn into the connecting box 18 by solenoid valves 9 and 31. At this time, air comes into contact with the surfaces of multiple first fins 33, causing their temperature to drop. The cold air enters the transparent glass cover 10 through the first solenoid valve 27 and the first hose 8, heating the interior of the transparent glass cover 10. When the temperature inside the transparent glass cover 10 is too low, the fourth solenoid valve 31 and the first solenoid valve 27 are closed, and the third solenoid valve 30 and the second solenoid valve 28 are opened. At this time, air drawn in by fan 19 comes into contact with the surfaces of multiple second fins 34, heating them. The hot air enters the transparent glass cover 10 through the second solenoid valve 28 and the first hose 8, raising the temperature. The temperature inside the transparent glass cover 10 is controlled between 5°C (hydraulic push rod) and 25°C (filter screen).This improved the growth and development of saffron.
