[0002] Rice is one of the most important food crops in the world, so rice cultivation plays a vital role in the steady development of agriculture.

[0003] Rice cultivation is closely related to humidity and temperature. Traditional artificial rice cultivation mainly uses equipment such as awnings and ventilation fans. Traditional artificial rice cultivation occupies a large area and relies heavily on the natural environment. The humidity and temperature control effect is poor, and the rice cultivation effect is not good.

[0004] In addition, traditional rice cultivation mostly uses refrigerators for cooling, which is not only inconvenient to operate, but also greatly increases the probability of failure in relatively harsh environments. In short, it will affect the stability of cooling and the yield of rice cultivation. Summary of the Invention

[0008] The box body provides fixed support for other components, the humidity and temperature control chamber provides a carrying space for other components, and the rice culture chamber provides a suitable environment for rice cultivation. The first ventilation port is located on the side away from the rice culture chamber, the second ventilation port is located between the humidity and temperature control chamber and the rice culture chamber, and the third ventilation port is located on the side away from the humidity and temperature control chamber. The first ventilation port, the second ventilation port and the third ventilation port provide a path for air to pass from the humidity and temperature control chamber to the rice culture chamber in sequence. The humidity and temperature detection device can measure the humidity and temperature of the rice cultivation environment in the rice culture chamber in real time. The humidity and temperature detection device can transmit the detection signal to the dehumidification and cooling device, the heating device and the water supply device through a wire connection. The support seat provides a fixing function for the dehumidification and cooling device, and the support base provides a fixing function for the heating device.

[0009] Furthermore, the humidity and temperature detection device is tightly connected to the rice cultivation chamber. The humidity and temperature detection device includes a first humidity detector, a second humidity detector and a temperature detector. The first humidity detector is tightly connected to the rice cultivation chamber, the second humidity detector is tightly connected to the rice cultivation chamber, and the temperature detector is tightly connected to the rice cultivation chamber.

[0010] The first humidity detector, temperature detector and second humidity detector are placed and fixed in sequence from bottom to top inside the rice culture chamber. The reason is that the humidity near the ground is relatively high because the density of moisture is greater than that of air. When the humidity rises to a certain level, the first humidity detector located at the bottom layer can timely measure the peak value of the humidity and transmit the signal to the dehumidification and cooling device through a wire connection. Similarly, when the humidity drops to a certain level, the second humidity detector located at the top layer can timely measure the valley value of the humidity and transmit the signal to the water supply device through a wire connection. The temperature detector located in the middle can accurately measure the real-time temperature inside the rice culture chamber and transmit the signal to other devices through a wire connection.

[0011] Furthermore, the dehumidification and cooling device is tightly connected to the humidity and temperature control chamber. The dehumidification and cooling device includes a first motor, fan blades, a first cover door, a pushing assembly, a second cover door, a push-pull assembly and a third cover door. The first motor is tightly connected to the support seat, the first motor is in contact with the heating device, the output end of the first motor is tightly connected to the fan blades, the exhaust end of the fan blades faces the second vent, the pushing assembly is tightly connected to the box body, the pushing assembly is tightly connected to the humidity and temperature control chamber, the second cover door is movably connected to the pushing assembly, the push-pull assembly is tightly connected to the box body, the first cover door is tightly connected to the push-pull assembly, and the third cover door is tightly connected to the push-pull assembly.

[0012] When the first humidity detector detects that the humidity peak in the rice cultivation chamber exceeds the set value, the first humidity detector starts the pushing component, the push-pull component and the first motor through the wire connection, and the pushing component outputs a linear displacement upward to drive the second cover door to move upward, thereby connecting the humidity and temperature control chamber and the rice cultivation chamber, and the push-pull component drives the first cover door and the third cover door to rotate axially in the vertical direction, and the first motor outputs torque to drive the fan blades to rotate and exhaust air toward the second vent, thereby achieving the effect of dehumidifying the rice cultivation chamber, and the heating device is used to supply water to absorb heat to the first motor, and the first motor and the heating device are in contact for heat exchange to prevent the first motor from accumulating Heat, ensuring the service life of the first motor, and at the same time utilizing the waste heat of the first motor to compensate for the temperature drop caused by the dehumidification process. When the temperature detector detects that the temperature in the rice cultivation chamber exceeds the set value, the temperature detector starts the pushing component, the push-pull component and the first motor through a wire connection. The first motor outputs torque to drive the fan blades to rotate and exhaust air toward the second vent, thereby achieving the effect of cooling the rice cultivation chamber. When the humidity detected by the second humidity detector and the temperature detected by the temperature detector simultaneously meet the corresponding set values, the first vent, the third vent and the connecting parts between the humidity and temperature control chamber and the rice cultivation chamber are closed at the same time.

[0013] Furthermore, the pushing assembly includes a second motor, a screw rod and a sliding rail. The second motor is fastened to the box body, the second motor is fastened to the humidity and temperature control chamber, the sliding rail is fastened to the second motor, the sliding rail is slidingly connected to the second cover door, the sliding rail includes a sliding groove, a rod bottom hole and a rod high hole, the sliding groove is slidingly connected to the second cover door, one end of the screw rod is fastened to the output end of the second motor, and the other end of the screw rod passes through the rod bottom hole of the slide rail and is movably connected to the rod high hole.

[0014] The second motor is fixed on the box body, and the second motor is located in the humidity and temperature control chamber. The slide rail is fixed on the second motor in the vertical direction. The output end of the second motor is tightly connected to one end of the screw rod, and the other end of the screw rod passes through the bottom hole of the rod of the slide rail and is movably connected to the high hole of the rod. When the pushing component receives the signal transmitted by other components, the second motor starts, and the output end of the second motor drives the screw rod to rotate.

[0015] Furthermore, a threaded hole is provided on the second cover door, which is threadedly connected to the screw rod. The push-pull assembly includes a first arm-lifting motor and a second arm-lifting motor. The first arm-lifting motor is fastened to the box body, the first cover door is fastened to the output end of the first arm-lifting motor, the second arm-lifting motor is fastened to the box body, and the third cover door is fastened to the output end of the second arm-lifting motor.

[0016] The threaded hole is threadedly connected to the screw rod. When the screw rod rotates, the second cover door is limited by the sliding groove, and the rotation of the screw rod is converted into vertical linear movement of the second cover door. The first arm motor is used to output torque to drive the first cover door to rotate, thereby controlling the opening of the first vent. The second arm motor is used to output torque to drive the third cover door to rotate, thereby controlling the opening of the third vent. When the push-pull component receives the relevant component signal, the first arm motor and the second arm motor are started at the same time, driving the first cover door and the third cover door to rotate axially in the vertical direction.

[0017] Furthermore, the box body includes a water pipe hole and a drainage hole, the heating device includes an electric heating rod box, a water pipe and a heat exchange pipe, the water pipe is connected to the water supply device pipeline, the water pipe is in contact with the first motor, one end of the water pipe passes through the water pipe hole, the other end of the water pipe passes through the drainage hole, the water pipe is firmly connected to the support base, the electric heating rod box is connected to the water pipe pipeline, the heat exchange pipe is firmly connected to the water pipe, the electric heating rod box includes a heater water inlet and a heater water outlet, the water pipe includes a heat exchange tank and a humidification port, the heat exchange tank is located on the side away from the water pipe hole, the humidification port is connected to the water supply device pipeline, the heater water outlet is connected to the water pipe pipeline, the heat exchange pipe is firmly connected to the heat exchange tank, the heat absorption end of the heat exchange pipe is inserted into the inside of the water pipe, and the heat dissipation end of the heat exchange pipe is placed outside the water pipe.

[0018] When the humidity in the rice cultivation chamber exceeds the set value, the fan blades will start to exhaust and dehumidify, and the system temperature in the rice cultivation chamber will inevitably drop to a certain extent. At this time, the temperature detector starts to detect the temperature. If the temperature in the rice cultivation chamber is less than or equal to the set value, groundwater will be introduced into the water pipe during the exhaust and dehumidification process. Because the water pipe and the first motor are in contact with each other for heat exchange, according to the principle of heat conduction, the internal energy generated by the first motor will be transferred to the groundwater in the pipe through the wall of the water pipe. The heated groundwater heats the heat absorbing end of the heat exchange pipe, and the heat exchange pipe then transfers the heat to the groundwater through the heat dissipation end. The amount is transferred to the air near the fan blades. During the dehumidification process of the fan blades, the heated air is sent into the rice culture chamber, thereby realizing heat compensation in the exhaust dehumidification process. When the humidity in the rice culture chamber returns to the set value, if the temperature detected by the temperature detector is still lower than the set value, the electric heating rod box heats the groundwater in the water pipe, and the heated groundwater heats the heat-absorbing end of the heat exchange tube. The heat exchange tube then transfers the heat to the air near the fan blades through the heat dissipation end, thereby increasing the instantaneous heat dissipation. When the hot air enters the rice culture chamber, temperature compensation is performed, thereby realizing that the temperature is raised to the set value.

[0019] Furthermore, the water supply device includes a groundwater pipe, a control pump and a humidifying component. The groundwater pipe is connected to the control pump pipeline, the control pump is connected to the heating device pipeline, the control pump is connected to the electric heating rod box pipeline, the control pump is connected to the heater water inlet pipeline, the humidifying component is connected to the heating device pipeline, the humidifying component is connected to the water supply pipe pipeline, the humidifying component is connected to the humidifying port pipeline, and the humidifying component passes through the humidifying hole of the box.

[0020] The temperature for rice growth is generally between 20℃ and 30℃, and the temperature of groundwater is generally between 10℃ and 25℃. The groundwater is heated by an electric heating rod box to make the groundwater temperature suitable for rice cultivation, which conforms to the design concept of energy saving and environmental protection. The groundwater source is used for water supply. The groundwater pipe is connected to the control pump pipe. The control pump controls the extraction of groundwater. The water supply device and the heating device share a set of pipeline systems. When the rice culture chamber needs to be humidified, the groundwater at a suitable temperature is transferred to the humidification component through the water pipe for spraying and humidification.

[0021] Furthermore, the control pump includes a water inlet and a water outlet, the water inlet is connected to the groundwater pipe, the water outlet is connected to the heating device through a pipe, the water outlet is connected to the electric heating rod box pipe, and the water outlet is connected to the heater water inlet pipe. The humidification component includes a humidification pipe and a humidification nozzle, the humidification pipe is connected to the humidification nozzle pipe, the humidification pipe is connected to the heating device pipe, the humidification pipe is connected to the water supply pipe, and the humidification pipe is connected to the humidification port pipe.

[0022] When the groundwater is insufficient to provide the heat required for rice cultivation, the water outlet is connected to the water inlet of the heater through a pipe. The groundwater is heated to a suitable temperature by the electric heating rods in the electric heating rod box and then sent to the water pipe. Because the humidification component is connected to the pipe of the water pipe, the heated groundwater can be used to humidify the rice cultivation chamber at a constant temperature through the humidification nozzle.

[0023] Compared with the prior art, the beneficial effect of the present invention is that when the humidity in the rice culture chamber exceeds the set value, the fan blades perform exhaust and dehumidification, and the system temperature in the rice culture chamber will inevitably drop to a certain extent. At this time, the temperature detector starts to detect the temperature. If the temperature in the rice culture chamber is less than or equal to the set value, groundwater is introduced into the water pipe during the exhaust and dehumidification process. Because the water pipe and the first motor are in contact with each other for heat exchange, according to the principle of heat conduction, the internal energy generated by the first motor will be transferred to the groundwater in the pipe through the wall of the water pipe, and the heated groundwater will heat the heat absorbing end of the heat exchange pipe, and the heat exchange The tube then transfers the heat to the air near the fan blades through the heat dissipation end. During the dehumidification process of the fan blades, the heated air is sent into the rice culture chamber, thereby realizing heat compensation for the exhaust dehumidification process. When the humidity in the rice culture chamber returns to the set value, if the temperature detected by the temperature detector is still lower than the set value, the electric heating rod box heats the groundwater in the water pipe. The heated groundwater heats the heat absorption end of the heat exchange tube, and the heat exchange tube then transfers the heat to the air near the fan blades through the heat dissipation end, thereby increasing the instantaneous heat dissipation. When the hot air enters the rice culture chamber, temperature compensation is performed, thereby raising the temperature to the set value. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the temperature detector 23 starts to detect the temperature. If the temperature in the rice cultivation chamber 12 is less than or equal to the set value, groundwater is introduced into the water pipe 42 during the exhaust and dehumidification process. Because the water pipe 42 and the first motor 31 are in contact with each other for heat exchange, according to the principle of heat conduction, the internal energy generated by the first motor 31 will be transferred to the groundwater in the pipe through the wall of the water pipe 42. The heated groundwater heats the heat absorbing end of the heat exchange pipe 43, and the heat exchange pipe 43 then transfers the heat to the groundwater through the heat dissipation end. Heat is transferred to the air near the fan blades 32. During the dehumidification process of the fan blades 32, the heated air is sent into the rice culture chamber 12, thereby achieving heat compensation during the exhaust and dehumidification process. When the humidity in the rice culture chamber 12 returns to the set value, if the temperature detected by the temperature detector 23 is still lower than the set value, the electric heating rod box 41 heats the groundwater in the water pipe 42. The heated groundwater heats the heat-absorbing end of the heat exchange tube 43, and the heat exchange tube 43 then transfers the heat to the air near the fan blades 32 through the heat dissipation end, thereby increasing the instantaneous heat dissipation. When the hot air enters the rice culture chamber 12, temperature compensation is performed, thereby achieving the temperature rising to the set value.

[0047] like Figure 4 、 Figure 7 、 Figure 8 As shown, the water supply device 5 includes a groundwater pipe 51, a control pump 52 and a humidifying component 53. The groundwater pipe 51 is connected to the control pump 52 through a pipeline. The control pump 52 is connected to the heating device 4 through a pipeline.

[0048] In agriculture, the suitable temperature required for the growth and cultivation of rice is between 20°C and 30°C. The temperature of groundwater varies slightly depending on the region, but is still between 10°C and 25°C. The groundwater is heated by the electric heating rod box 41 to make the groundwater temperature suitable for rice cultivation, which conforms to the design concept of energy saving and environmental protection. The groundwater source is used for water supply. The groundwater pipe 51 is connected to the control pump 52 pipeline. The control pump 52 controls the extraction of groundwater. The water supply device 5 and the heating device 4 share a set of pipeline systems. When the rice culture chamber 12 needs to be humidified, the groundwater at the appropriate temperature is transferred to the humidification component 53 through the water pipe 42 for spraying and humidification.

[0050] When the groundwater is insufficient to provide the heat required for rice cultivation, the water outlet 522 is connected to the water inlet 411 of the heater through a pipe. The groundwater is heated to a suitable temperature by the electric heating rods in the electric heating rod box 41 and then sent to the water pipe 42. Because the humidification component 53 is connected to the pipe of the water pipe 42, the heated groundwater can be used to humidify the rice cultivation chamber 12 at a constant temperature through the humidification nozzle 532.
