[0001] The utility model relates to the field of seed cultivation device especially corn seed high temperature resistant detection device. BACKGROUND

[0002] The corn seed high temperature resistant detection device is a device specially used for evaluating the tolerance of corn seeds in a high temperature environment, simulating high temperature conditions, testing the germination rate, growth potential and physiological activity of seeds in extreme temperatures, and judging the high temperature resistance of seeds.

[0003] At present, the Chinese patent application with the authorization announcement number CN 205538782 U and the authorization announcement date August 31, 2016 proposes a kind of seed high temperature resistant special detection device, the inside lower portion of detection device is equipped with U-shaped groove, U-shaped groove is equipped with drawer box, the right end of the top inner side of detection device is equipped with temperature sensor, the outer wall of the right side of detection device is sequentially equipped with shunt control switch and controller from top to bottom, first electric heating block, second electric heating block and third electric heating block are electrically connected with shunt control switch by wire respectively, temperature sensor and shunt control switch are electrically connected with controller by wire.

[0004] When using, the power supply of first electric heating block, second electric heating block and third electric heating block can be turned off or turned on by shunt control switch controlled by controller, different temperature regulation can be realized, and the use of temperature sensor is adjusted simultaneously.

[0005] For the above related technology, the high temperature resistant detection of seed is mainly to make seed grow better in soil after sowing, the environment and physical characteristics of air and soil are different, directly placing seed in air with parameter setting detects, the physical characteristics of air and soil are different, which will cause great difference between seed growth in soil and test result. INVENTION CONTENTS

[0006] In order to improve the consistency of test result of seed high temperature resistance and seed growth in soil, the utility model provides a corn seed high temperature resistant detection device.

[0007] The utility model provides a corn seed high temperature resistant detection device, adopt following technical scheme:

[0008] A high-temperature resistance testing device for corn seeds includes a testing chamber, a heating device installed inside the testing chamber, and a controller installed outside the testing chamber. The heating device is electrically connected to the controller. The device also includes a cultivation trough containing soil, with water absorption holes at the bottom; a temperature sensor installed inside the cultivation trough and electrically connected to the controller for detecting soil temperature; a humidity sensor installed inside the cultivation trough and electrically connected to the controller for detecting soil moisture; a water tank containing water installed below the cultivation trough, with the bottom of the cultivation trough immersed in water; and the heating device installed above the cultivation trough.

[0009] By employing the above technical solution, when testing the high-temperature resistance of seeds, firstly, soil is filled into a cultivation trough; secondly, the seeds are buried in the soil; thirdly, an appropriate amount of water is added to a water tank, and the cultivation trough is placed above the water tank so that the water intake holes at the bottom of the cultivation trough just reach the water in the water tank; finally, the water tank and cultivation trough are placed together in a testing chamber, and the heating device in the testing chamber is turned on to heat the soil. Temperature and humidity sensors in the cultivation chamber monitor the temperature and humidity in the soil in real time, ensuring that the seeds are in a relatively stable soil environment. In this way, by using the water tank and heating device, the environmental parameters of the soil are set to be the same as those of the outdoor seed growth environment, simulating the actual growth environment for the seeds and conducting high-temperature resistance tests. This makes the high-temperature resistance test results more consistent with the actual outdoor growth conditions of the seeds, improving the consistency between the high-temperature resistance test results and the actual growth conditions of the seeds.

[0010] Optionally, it also includes a water replenishment component, which includes a water replenishment tank fixedly disposed outside the detection chamber; a water guide pipe, one end of which is connected to the water replenishment tank and the other end of which is connected to the inside of the detection chamber; and a quick connector fixedly disposed at the end of the water guide pipe that connects to the inside of the detection chamber, the quick connector being used to connect to the water tank.

[0011] When testing seeds, the immersion depth of the cultivation tank in water should be kept consistent to maintain relatively uniform soil moisture. However, seed growth and high temperatures cause water evaporation, which leads to a decrease in the water level in the tank, thus reducing the immersion depth. To maintain a relatively uniform water level, water needs to be added to the tank regularly. However, frequently opening the testing chamber to add water can cause temperature fluctuations in the cultivation tank, affecting the test results.

[0012] By adopting the above technical solution, when water needs to be added to the tank, water can be added directly to the water replenishment chamber outside the testing chamber. The water in the replenishment chamber will flow into the tank through the water guide pipe and quick connector, thereby controlling the water level in the tank to be relatively uniform. There is no need to open the testing chamber to replenish water, reducing the disturbance to the temperature in the culture tank and improving the accuracy of the test results. The quick connector allows for quick connection between the water replenishment chamber and the tank when the tank is removed or placed into the testing chamber, making it more convenient to use.

[0013] Optionally, the bottom of the water replenishment tank is at the same horizontal line as the bottom of the water tank, and a scale line is provided on the water replenishment tank. The height of the scale line is at the same horizontal line as the bottom of the cultivation tank. The water guide pipe is connected to the bottom of the water replenishment tank, and a water inlet is provided at the bottom of the water tank. The water inlet is connected to the quick connector.

[0014] When adding water to the tank through the water replenishment chamber, the amount of water in the tank cannot be directly observed; water can only be added based on set times and experience, which is inconvenient. By adopting the above technical solution, the bottom of the water replenishment chamber is set to the same height as the bottom of the tank, and the inlets of the bottom of the water replenishment chamber and the bottom of the tank are connected by a water pipe. This makes the water replenishment chamber and the tank a communicating vessel. When adding water to the tank through the water replenishment chamber, the water level in the tank can be directly observed to determine the water level in the tank, making the water replenishment amount more intuitive and easier to use. The scale line provides a reference for the height of the suction hole. Each time water is added, if the water level is below the scale line, the soil cannot absorb water from the tank. Therefore, water needs to be added whenever the water level in the water replenishment chamber is below the scale line, providing a reference for when to add water and further improving ease of use.

[0015] Optionally, it also includes a converging component, which includes: a fixing plate, fixedly installed inside the detection chamber and positioned above the incubation tank, the fixing plate being used to support the heating device; multiple wing plates, all of which are installed on the edge of the fixing plate, the multiple wing plates and the downward-facing end face of the fixing plate being concave in overall configuration, and the downward-facing end faces of the fixing plate and the wing plates being mirror-like; the mirror-like side of the fixing plate and the wing plates is used to converge heat radiation.

[0016] By adopting the above technical solution, the heating device is installed at the bottom of the fixed plate during installation, and the wing plate surrounds the fixed plate. The fixed plate and the wing plate have a concave structure on the side where the heating device is installed. The side of the fixed plate and the wing plate with the concave structure is also set as a mirror, so that the fixed plate and the wing plate as a whole have a concave mirror structure. When the heating device heats, the concave mirror structure can concentrate the heat radiation above the soil, reduce the heat radiation from spreading in all directions, and improve the energy utilization rate.

[0017] Optionally, multiple wing plates are rotatably mounted on the edge of the fixed plate.

[0018] By adopting the above technical solution, the rotating wing plate can adjust the direction of thermal radiation reflection, thereby adjusting the range of thermal radiation convergence on the soil. This allows for flexible adjustment of the convergence range of thermal radiation when the soil area is different, ensuring that the convergence range of thermal radiation only covers the soil area, thus further improving energy utilization.

[0019] Optionally, the detection chamber is further provided with an air inlet and an air outlet, and a circulation fan is provided on the air inlet and / or the air outlet, and the circulation fan is electrically connected to the controller.

[0020] By adopting the above technical solution, in order to more realistically simulate the seed growth environment, the setting of air inlet and outlet can connect the air inside the detection chamber with the air in the external environment, so that the soil is exposed to air with the same oxygen and carbon dioxide content as the outside air, allowing the soil to fully absorb oxygen and carbon dioxide from the air, and further improving the consistency between the seed high temperature resistance test results and the actual seed growth.

[0021] Optionally, a heat exchange device is also connected to the air inlet. The heat exchange device is hollow inside. One end of the heat exchange device is connected to the air outlet, and the other end of the heat exchange device is connected to the outside of the detection chamber.

[0022] By adopting the above technical solution, when the testing chamber exchanges air with the outside environment through the air inlet and outlet, the warmer air inside the testing chamber first flows into the heat exchanger, where its temperature is transferred, before flowing out of the testing chamber. The heat exchanger is installed at the air inlet. When air from the outside environment flows into the testing chamber through the air inlet, it is first heated by the heat exchanger at the air inlet before flowing into the testing chamber. In this way, the heat exchanger recovers a portion of the heat from the warm air leaving the testing chamber and uses this recovered heat to heat the air flowing into the testing chamber. This improves energy efficiency and reduces temperature fluctuations caused by the influx of cooler air from the outside environment into the testing chamber.

[0023] Optionally, the air inlet and the air outlet are respectively located on two opposite side walls of the detection chamber.

[0024] By adopting the above technical solution, the air inlet and outlet are set on two opposite side walls of the testing chamber, so that when the testing chamber exchanges air with the external environment, the air can flow evenly from one side of the testing chamber to the other side, so that the soil in the cultivation tank can be evenly swept by the airflow, and the temperature inside the testing chamber can be relatively more uniform.

[0025] Optionally, the inner wall of the testing chamber is also provided with a heat insulation layer.

[0026] By adopting the above technical solution, the insulation layer can effectively slow down the transfer of temperature from the inside of the testing chamber to the external environment, thereby maintaining the soil inside the testing chamber at a more stable temperature and reducing energy consumption.

[0027] In summary, this utility model has at least one of the following beneficial technical effects:

[0028] This application places the cultivation trough above the water tank and below the heating device. When testing the high-temperature resistance of seeds, soil is placed in the cultivation trough, and the seeds are placed in the soil-filled cultivation trough for high-temperature resistance testing. This simulates the actual growth environment for the seeds, making the high-temperature resistance test results more consistent with the actual situation of seeds growing outdoors, and improving the consistency between the high-temperature resistance test results and the actual growth of the seeds.

[0029] When replenishing soil moisture, this application connects the water replenishment chamber to the bottom of the water tank via a water pipe to form a communicating vessel. Water can be directly injected into the water tank through the external water replenishment chamber, reducing temperature fluctuations caused by frequent opening and closing of the detection chamber. The height of the scale line of the water replenishment chamber is aligned with the position of the water absorption hole in the cultivation tank, providing an intuitive reference for water replenishment, ensuring consistent soil water absorption depth, and improving soil moisture stability.

[0030] The heating device is installed between a fixed plate and multiple wing plates. The fixed plate and multiple rotatable wing plates form a concave mirror structure. The surfaces of the fixed plate and wing plates near the heating device are mirror-treated to reflect and concentrate the heat radiation of the heating device, so that the heat radiation is concentrated in a specific area and energy waste is reduced.

[0031] A circulating fan is installed at the air inlet or outlet, and the high-temperature air discharged from the outlet flows through a heat exchange device to preheat the air entering the testing chamber from the air inlet, thereby reducing energy loss. Attached Figure Description

Detailed Implementation

[0039] The following combination Figures 1 to 6 The present invention will be described in further detail below.

[0040] This utility model discloses a device for testing the high-temperature resistance of corn seeds. (Refer to...) Figures 1 to 3 A high-temperature resistance testing device for corn seeds mainly includes a testing chamber 100, a heating device 200 installed inside the testing chamber 100, and a cultivation trough 400 installed inside the testing chamber 100. The heating device 200 is located on the top of the inner wall of the testing chamber 100. A water tank 430 is located below the cultivation trough 400. A water suction hole 401 is located at the bottom of the cultivation trough 400. The cultivation trough 400 is connected to the inside of the water tank 430 through the water suction hole 401 at the bottom. A temperature sensor 410 and a humidity sensor 420 are also installed inside the cultivation trough 400. A controller 300 is installed on the testing chamber 100. The heating device 200, the temperature sensor 410, and the humidity sensor 420 are all electrically connected to the heating device 200.

[0041] In use, the cultivation trough 400 is filled with soil, and water is placed in the water tank 430. The soil inside the cultivation trough 400 can absorb water from the water tank 430 through the water absorption holes 401 at the bottom of the cultivation trough 400. Then, the seeds to be tested are shallowly buried in the soil in the cultivation trough 400. The heating device 200 is controlled by the controller 300 to heat the soil in the cultivation trough 400. The temperature and humidity in the soil are monitored in real time by the temperature sensor 410 and the humidity sensor 420. Based on the feedback information, the controller 300 adjusts the heating device 200 in real time to ensure that the seeds are tested in soil with relatively stable temperature and humidity. This makes the high temperature resistance test results of the seeds more consistent with the actual growth of the seeds in the soil, and thus makes the high temperature resistance test results of the seeds more accurate.

[0042] Reference Figure 1A controller 300 is fixedly installed on the top of the outer wall of the testing chamber 100. The display screen and control buttons on the controller 300 make it more convenient for users to use. An air inlet 101 is provided on the right side wall of the testing chamber 100, and an air outlet 102 is provided on the left side wall of the testing chamber 100. When the cabinet door of the testing chamber 100 is closed, outside air can enter the testing chamber 100 through the air inlet 101 on the right side wall of the testing chamber 100, and the air inside the testing chamber 100 can be discharged through the air outlet 102 on the left side wall of the testing chamber 100, so that the inside of the testing chamber 100 can exchange air with the outside environment.

[0043] Reference Figure 3 In order to accelerate the exchange of air between the inside and outside of the detection chamber 100 when it is in a closed environment, a circulation fan 110 is fixedly installed at the air inlet of the detection chamber 100. The circulation fan 110 is electrically connected to the controller 300. By controlling the circulation fan 110 to turn on through the controller 300, the exchange of air between the inside and outside of the detection chamber 100 can be accelerated, thereby providing sufficient oxygen and carbon dioxide for the seeds inside the detection chamber 100.

[0044] Reference Figure 3 and Figure 4 Two connecting rods are fixedly installed on the top of the inner wall of the detection chamber 100. A converging assembly 600 is fixedly installed on the connecting rods. The converging assembly 600 includes a fixed plate 610 and multiple wing plates 620 rotatably installed on the edge of the fixed plate 610. The fixed plate 610 is fixedly installed on the connecting rods at the top of the detection chamber 100. The multiple wing plates 620 are rotatably installed on the edge of the fixed plate 610 through damping hinges. The downward-facing end faces of the fixed plate 610 and the wing plates 620 are mirror-like. Rotating and tilting the multiple wing plates 620 can make the fixed plate 610 and the multiple wing plates 620 as a whole form a concave mirror.

[0045] In this embodiment, the heating device 200 uses a heating tube, specifically a quartz heating tube. The quartz heating tube is fixedly installed on the inner side of the fixed plate 610 and multiple wing plates 620, which are arranged in a concave mirror configuration. This can concentrate the heat radiation emitted by the quartz heating tube. Furthermore, the concave mirror formed by the fixed plate 610 and multiple wing plates 620 is positioned downwards, which allows the heat radiation emitted by the heating device 200 to be concentrated on the soil in the cultivation tank 400, reducing the dispersion of heat radiation and thus reducing energy consumption.

[0046] Reference Figure 3 In order to reduce the heat loss caused by the transfer of the internal temperature of the detection chamber 100 to the external environment, the detection chamber 100 adopts a double-layer structure, and an insulation layer 120 is set between the inner and outer layers to slow down the heat loss. Specifically, the insulation layer 120 can be filled between the inner and outer layers of the detection chamber 100 with materials such as insulation cotton and foam.

[0047] Because the internal environment of the testing chamber 100 needs to exchange air with the external environment, when the air inside the testing chamber 100 flows into the external environment, the heat inside the testing chamber 100 will flow to the outside of the testing chamber 100 with the air, resulting in a lot of heat loss.

[0048] Reference Figure 3 and Figure 5 To reduce heat loss during air exchange between the internal and external environments of the testing chamber 100, a heat exchange device 700 is installed at the air inlet 101 and air outlet 102 of the testing chamber 100. The heat exchange device 700 includes two air ducts 710 and a heat sink 720. The heat sink 720 is fixedly installed at the air inlet 101 of the testing chamber 100. One end of the first air duct 710 is connected to the heat sink 720, and the other end is connected to the air outlet 102 on the inner layer of the testing chamber 100. One end of the second air duct 710 is connected to the heat sink 720, and the other end is connected to the air outlet 102 on the outer layer of the testing chamber 100. When the internal environment of the testing chamber 100 exchanges air with the external environment, the high-temperature air inside the testing chamber 100 first flows through the air outlet 102 on the inner layer of the testing chamber 100, through the first air duct 710, and then into the heat sink 720. After heat exchange by the heat sink 720, the cooled air flows out of the testing chamber 100 through the air outlet on the outer layer of the testing chamber 100 through the second air duct 710. When the air in the external environment of the testing chamber 100 enters the testing chamber 100, the air in the external environment will absorb the heat emitted by the heat sink 720 and enter the testing chamber 100 after being heated.

[0049] In this way, the heat in the air that needs to flow out of the detection chamber 100 is transferred to the air that needs to enter the detection chamber 100 through the heat dissipation device. On the one hand, this can reduce the heat loss caused by the air flowing out of the detection chamber 100, thus saving energy. On the other hand, it can also preheat the air entering the detection chamber 100, reducing the temperature fluctuation inside the detection chamber 100.

[0050] Reference Figure 1 and Figure 6 The cultivation tank 400 is placed at the bottom of the detection chamber 100. The cultivation tank 400 and the water tank 430 are configured together. The top of the water tank 430 is provided with a fitting groove, and the bottom of the cultivation tank 400 can be placed in the fitting groove so that the bottom of the cultivation tank 400 can be supported above the water tank 430. The bottom of the cultivation tank 400 is provided with a water suction hole 401 so that when the water tank 430 is filled with water, the bottom of the cultivation tank 400 can be immersed in the water.

[0051] To facilitate observation of soil moisture and temperature in the cultivation tank 400 and make the detection environment more accurate, a temperature sensor 410 and a humidity sensor 420 are fixedly installed on the cultivation tank 400. The temperature sensor 410 and the humidity sensor 420 are respectively installed on two opposite side walls of the cultivation tank 400, and both the temperature sensor 410 and the humidity sensor 420 are electrically connected to the controller 300 outside the detection chamber 100.

[0052] Reference Figure 6 The water tank 430 has a water inlet 431 at its bottom, located outside the water tank 430. To facilitate water replenishment to the water tank 430 from outside the detection chamber 100, a water replenishment assembly 500 is also provided on the detection chamber 100. The water replenishment assembly 500 includes a water replenishment tank 510, a water guide pipe 520, and a quick connector 530. The water replenishment tank 510 is fixedly installed on the outer wall of the detection chamber 100. One end of the water guide pipe 520 is connected to the bottom of the water replenishment tank 510, and the water guide pipe 520... The other end of the 20 is connected to the inside of the detection chamber 100. The quick connector 530 is fixedly installed at one end of the water pipe 520 that connects to the inside of the detection chamber 100. The side wall of the detection chamber 100 is provided with a groove for storing the water pipe 520 and the quick connector 530. The quick connector 530 is configured to cooperate with the water inlet 431 at the bottom of the water tank 430 so that when the water tank 430 is placed inside the detection chamber 100, the water tank 430 can be quickly connected to the water replenishment tank 510.

[0053] To facilitate observation of water replenishment, the bottom of the water replenishment tank 510 is at the same horizontal level as the bottom of the water tank 430, and a scale line 511 is provided on the water replenishment tank 510 at the same horizontal height as the bottom of the cultivation tank 400.

[0054] In use, water can be added directly to the water replenishment tank 510 outside the detection chamber 100. The water in the water replenishment tank 510 will flow into the water tank 430 through the water guide pipe 520 and quick connector 530. Since the water level in the water tank 430 is the same as the water level in the water replenishment tank 510, the water level inside the water tank 430 can be determined by directly observing the water level in the water replenishment tank 510. The scale line 511 can also be used as a reference to make the water replenishment amount more intuitive.

[0055] The implementation principle of the high-temperature resistance testing device for corn seeds in this embodiment of the utility model is as follows: First, connect the water inlet 431 at the bottom of the water tank 430 to the quick connector 530 to connect the water replenishment chamber 510 to the water tank 430. Next, place the cultivation trough 400 above the water tank 430, and fill the cultivation trough 400 with soil and bury the seeds to be tested. Then, place the cultivation trough 400 and the water tank 430 together into the testing chamber 100, and adjust the wing plate 620 of the converging component 600 so that the heat radiation can be concentrated above the soil. Finally, close the cabinet door of the testing chamber 100, add water above the scale line 511 to the water replenishment chamber 510, and set the working parameters of the heating device 200 and the circulating fan 110 on the controller 300. During the testing process, the environmental parameters can also be observed and adjusted through the controller 300 to keep them relatively stable.

[0056] In summary, this application places seeds in soil for high-temperature resistance testing, simulating the actual growth environment for the seeds, making the high-temperature resistance test results more consistent with the actual situation of seeds growing outdoors; furthermore, a converging component 600 is installed on the heating device 200, which can reflect and concentrate the heat radiation from the heating device 200, focusing the heat radiation on a specific area and reducing energy waste; when replenishing water to the soil, the water replenishment chamber 510 and the bottom of the water tank 430 are connected by a water pipe 520 to form a communicating vessel, which can... Water can be directly injected into the water tank 430 through the external water replenishment tank 510, reducing temperature fluctuations caused by frequent opening and closing of the detection chamber 100; and the height of the scale line 511 of the water replenishment tank 510 is aligned with the position of the water suction hole 401 of the cultivation tank 400, providing an intuitive reference for water replenishment, ensuring consistent soil water absorption depth, and improving soil moisture stability; the setting of the circulation fan 110 can also allow the high-temperature air discharged from the air outlet 102 to flow through the heat exchange device 700 to preheat the air entering the detection chamber 100 from the air inlet 101, reducing energy loss.

[0057] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made according to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
