[0003] Publication No. CN 114885711 B discloses an agricultural meteorological drought simulation test observation device. By setting a ventilation mechanism, the staff can loosen the limit bolt when necessary. After the limit bolt is loosened, the staff can hold the handle to push the baffle upward. After the baffle is pushed upward to the limit position, the staff can screw the limit bolt into the limit hole in the sleeve block to limit and fix the baffle. At the same time, the staff can use the same method to lift and fix the side baffle. After the baffle and the side baffle are pulled up, the entire device can achieve three-sided ventilation. At the same time, the staff can record the growth of crops in real time according to the recording layer. The ventilation mechanism improves the practicality of the device body, and can achieve ventilation and record relevant growth data when planting crops, thereby improving the accuracy of the simulation test. However, the patent still has the following problems in actual use:
[0004] When the agricultural meteorological drought simulation test observation device uses the ventilation mechanism to blow air to the device body, due to the large temperature difference between the outside temperature and the internal temperature of the device body, the cold air from the outside will enter the interior of the device body, thereby lowering the temperature inside the device body, thereby affecting the drought conditions inside the device body and affecting the accuracy of the experimental data. At the same time, the ventilation mechanism can only blow air from one direction, and drought will occur in different seasons, and the wind direction in different seasons is different. Wind can aggravate soil drought and cause soil erosion. Windy weather in arid areas and drought seasons increases soil moisture consumption and aggravates drought. Strong winds blow away a large amount of topsoil, causing wind erosion and desertification - starting from surface wind erosion, through weathering, the development of flaky quicksand and the formation of dense sand dunes, so the blowing conditions cannot be simulated, affecting the accuracy of the data.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the observation equipment for agricultural meteorological drought simulation test uses a rotating motor to drive the rotating bevel gear to rotate, and uses the characteristics of the meshing connection between the rotating bevel gear and the meshing bevel gear ring to realize the rotation of the rotating ring, and drives the fan to rotate through the rotating ring, so that winds of different wind directions can be simulated, and crops can be blown from different directions. The height of the lifting plate is changed by the lifting motor, so that the planting box is close to the fluorescent lamp and the ultraviolet lamp and away from the collection box, so that the crops can be close to the fluorescent lamp and the ultraviolet lamp, the temperature of the crop irradiation is increased, and the simulation of drought light conditions is convenient. The specific contents are as follows:
[0022] 1. By setting up the wind direction adjustment mechanism, not only can the rotating motor be used to drive the rotating bevel gear to rotate, but also the characteristics of the meshing connection between the rotating bevel gear and the meshing bevel gear ring can be used to realize the rotation of the rotating ring. The rotating ring drives the fan to rotate, so as to simulate winds of different wind directions and blow wind to crops from different directions. Wind can aggravate soil drought and cause soil erosion. Windy weather in arid areas and dry seasons increases soil moisture consumption and aggravates drought. Strong winds blow away a large amount of topsoil, causing wind erosion and desertification - starting from surface wind erosion, through weathering, the development of sheet-like quicksand and the formation of dense sand dunes. By changing the wind direction, it is convenient to observe the influence of different wind directions on the growth of crops. By setting up a heating device, hot wind can be generated when blowing, so as to quickly heat up the interior of the observation device. At the same time, the annular air duct is used to realize the circulation of wind, avoid the circulation of wind and external air, and allow the cold air from the outside to enter the interior of the observation device, thereby affecting the accuracy of the simulation experimental data;
[0023] 2. By setting the observation mechanism, not only can the lifting motor be used to drive the sprocket transmission assembly to drive the lifting two-way threaded rod to rotate, so that the lifting threaded sleeve can move relatively on the lifting two-way threaded rod, and at the same time, the first lifting rotating rod can be mobilized to rotate, thereby driving the lifting plate to lift and move. By changing the height of the lifting plate, the planting box is close to the fluorescent lamp and the ultraviolet lamp and away from the collection box, so that the crops can be close to the fluorescent lamp and the ultraviolet lamp, and the temperature of the crops can be increased, which is convenient for simulating drought light conditions. When the lifting plate is lifted, the second lifting rotating rod will be driven to rotate, so that the limiting slider on the top of the top connecting support slides in the limiting sliding groove at the bottom of the first cover plate. When the first cover plate needs to be opened to replace the planting box, the sliding sleeve drives the limiting rotating rod and the limiting claw to slide into the limiting sliding groove by pressing the connecting support plate, and the elastic force of the limiting spring is used to make the limiting plate move downward, so that the limiting rotating rod and the limiting claw can be expanded, so as to The limit slider is limited, and under the action of the first hinge, the first cover plate is flipped, and the lifting plate drives the limit plate and the planting box to move to the top of the connecting bracket. The limit plate and the planting box can be taken out from the inside of the lifting plate through the first handle, so as to facilitate the replacement of the planting box. When it is necessary to sample and observe some crops, in order to avoid rapid heat loss, the locking pin is driven by toggling the unlocking paddle to squeeze the locking spring and slide inside the locking slide. When the locking pin is separated from the locking sleeve, the second cover plate can be opened through the second handle for rapid sampling. The rainwater condition is simulated by the spray tank and the spray head, the excess rainwater can be filtered by the permeable net, and the rainwater can be recovered by the collection box. The temperature and humidity inside the observation box can be monitored by the temperature sensor and the humidity sensor, and the crops can be observed through the display, which is convenient for simulating crop drought.

The temperature and humidity inside the observation box 201 can be monitored through the temperature sensor 210 and the humidity sensor 211, and the crops can be observed through the display 202, so as to simulate the drought of the crops. Finally, the rotating motor 106 drives the rotating bevel gear 107 to rotate, and the rotating ring 105 is rotated by utilizing the meshing connection between the rotating bevel gear 107 and the meshing bevel gear ring 108. The rotating ring 105 drives the fan 110 to rotate, so as to simulate winds of different directions and blow wind to the crops from different directions. Wind energy can aggravate soil drought.Windy weather in arid areas and dry seasons increases soil moisture consumption, aggravates drought conditions, and strong winds blow away a large amount of topsoil, causing wind erosion and desertification - starting from surface wind erosion, through weathering, the development of sheet-like quicksand and the formation of dense sand dunes. By changing the wind direction, it is easy to observe the effects of different wind directions on crop growth. By setting up a heating device 113, hot air can be generated during blowing, thereby quickly heating up the interior of the observation device. At the same time, the annular air duct 114 is used to realize wind circulation, avoid the circulation of wind and outside air, and allow the outside cold air to enter the interior of the observation device, thereby affecting the accuracy of the simulation experiment data.
