Description

Technical Field

[0001] The invention relates to the technical field of agriculture, in particular to a testing device for testing drought resistance of peanuts. Background Art

[0002] In order to ensure that peanuts can have a better yield in a drought environment, drought resistance tests are usually conducted after the seeds with drought resistance are cultivated, which provides a scientific basis for the selection and breeding of peanut varieties and the optimization of planting technology.

[0003] The existing test device places peanut seeds on a support net and uses a heating plate to generate heat to heat the support net, thereby drying the peanut seeds and creating a high-temperature environment. At the same time, the temperature and humidity data in the test box are detected in real time through a temperature sensor and a humidity sensor, so as to study the drought resistance of peanut seeds under different temperature and humidity conditions;

[0004] For the existing test devices, firstly, in the natural environment, the drought resistance of peanuts is affected by a variety of complex and uncontrollable factors. The environment simulated by traditional devices is often relatively simple and idealized, which is quite different from the complex and changeable drought environment in nature. Secondly, in the process of simulating the dry environment, the temperature of the internal gas will rise with the simulation process, and this part of the gas will be discharged from the equipment as it circulates, so that the heat energy contained in this part of the gas will be lost in vain. A large amount of waste heat cannot be effectively recovered and reused, resulting in energy waste and increasing the cost of peanut planting tests. Finally, after adding nutrient solution, water retaining agent or other substances, some substances will adhere to the inner wall of the water tank. Over time, these residual substances will gradually deteriorate, and it is difficult to clean them up manually in time, especially during long experiments. Cleaning will be delayed due to negligence of staff or tight experimental arrangements, resulting in residual substances having a continuous adverse effect on water quality. Summary of the invention

[0020] The present invention provides a testing device for testing drought resistance of peanuts. It has the following beneficial effects:

[0021] 1. In the present invention, during the process of simulating drought, as time goes by, the soil moisture decreases due to evaporation. The central control system can coordinate the water pump to replenish moisture in a timely and appropriate amount through the drip irrigation head to maintain the soil moisture at a level that meets the current drought simulation stage; at the same time, the light intensity of the light lamp can be changed accordingly according to the data of the light intensity sensor, and the fan and the heating plate will also be started or the power adjusted as needed to ventilate and heat the air, so that the temperature changes accordingly, thereby creating a dynamic drought environment scene in which multiple factors such as light, temperature, and soil moisture change continuously and interrelated with time, which is more in line with the real change law of various factors in the natural environment. When the peanut seeds grow into plants, according to the different needs of the plants for nutrients in different drought stages, the corresponding nutrients can be added to the water tank through the feeding port, and the motor drives the stirring rod to rotate to ensure that the nutrients and water are evenly mixed, and then the plants are accurately supplied through the drip irrigation system, ensuring that the peanut plants can grow normally and accurately present their drought resistance performance in the simulated dynamic drought environment.

[0022] 2. In the present invention, after the air pump conveys the collected waste heat gas to the annular tube through the collection hopper, the waste heat gas circulates between the annular tubes with the help of the circulation tube and fully contacts the water in the water tank, thereby extending the heat exchange time and increasing the heat exchange area. This structure enables the heat in the waste heat gas to be transferred to the water in the water tank to the maximum extent, achieving effective preheating or heat preservation of the liquid in the water tank. The recovered waste heat is used to preheat the water in the water tank, so that the subsequent configuration of nutrient solution, drip irrigation and other operations can reduce the additional heating energy consumption, significantly improve the utilization efficiency of waste heat, and reduce energy waste.

[0023] 3. In the present invention, the rotating ring is driven by the second motor to drive the scraper on the mounting plate to rotate along the inner wall of the water tank through the connecting rod, so as to effectively scrape off the residual liquid and impurities on the inner wall of the water tank to prevent their accumulation and deterioration that affect the water quality and the growth of peanuts. Compared with the traditional water tank that relies on manual regular cleaning or simple flushing, this active cleaning method greatly improves the cleaning efficiency and maintenance convenience of the water tank, ensures that the water tank always maintains a good working condition during long-term use, and provides a stable and reliable supply of water and nutrient solution for peanuts.

[0047] Analysis module: It analyzes the data collected in the central control system through the data processing unit;

[0048] Driving module: It drives the fan 701, the heating plate 702, the lighting lamp 1202 and the water pump 810 through the analyzed information.

[0049] Working principle: After opening the hatch 2, plant the desired peanut seeds into the planting frame 603, then push the handle 604, so that the planting frame 603 slides through the slider 1 602 and the slide rail 601, and the planting frame 603 arrives under the lighting board 1201, then the hatch 2 is closed, the mobile motor 806 is started, and the mobile motor 806 rotates the worm gear 805, and the meshing relationship between the worm gear 805 and the worm 804 causes the slider 2 803 to slide on the slide bar 8022, and the sliding slider 2 803 drives the mounting frame 807 and the connecting platform 808 to move, so that the drip irrigation head 809 is aligned with the desired seeds, and then the water pump 81 0 Water in the water tank 9 is drawn to the connection platform 808, and dripped out from the drip irrigation head 809 to drip irrigate the peanut seeds. The light lamp 1202 is started to illuminate the seeds. When simulating a drought environment, the fan 701 is started to draw in circulating air, and the heating plate 702 heats the drawn air. The heated gas enters the installation inner cabin 3 to heat the soil. Then, according to the light intensity sensor 1203, the light intensity of the light lamp 1202 is changed, and the soil moisture sensor 811 is used to make the soil close to the state under natural drought. After the peanut seeds grow into plants, when it is necessary to simulate different drought environments, it is necessary to add water to the peanut seeds. The seeds or plants are added with certain nutrients. After the nutrients are added to the water tank 9 from the feeding port 1004, the motor 1001 is started, and the motor 1001 rotates the stirring rod 1003 on the mounting shaft 1002. In the simulated drought process, the gas with waste heat is collected by the air pump 1102 and the collecting bucket 1101, and flows to the annular pipe 1103 on the connecting plate 1104. Then, under the circulation of the circulation pipe 1105, the water tank 9 is preheated to make the substances and water merge quickly. The prepared nutrient solution is drip-irrigated to the peanut seeds again through the drip irrigation head 809. When the water pump 810 is in the extraction process, the motor 2 1304 Start, after the motor 2 1304 is started, the driving gear 1303 is rotated, and the rotating driving gear 1303 is meshed with the driven rack 1302, so that the rotating ring 1301 is rotated. When the rotating ring 1301 rotates, the scraper 1307 also rotates under the connection of the connecting rod and the mounting plate 1306. The rotating scraper 1307 prevents the residue from adhering to the inner wall of the water tank 9. The state of the plant is observed through the observation camera 1403 and the observation window 5 on the observation frame 1402. The transpiration rate meter 1404 detects the transpiration rate of the plant, and the detection data is fed back to the data display screen 1401 for the staff to view.
