Description

Technical Field

[0001] This utility model relates to the technical field of experimental equipment for plant seed germination, and more specifically, to an experimental device for the germination of wild crested wheatgrass seeds with controllable moisture content. Background Technology

[0002] As a plant of significant value in ecological restoration and livestock development, the study of its seed germination characteristics is crucial. Seed germination is a complex physiological process influenced by a combination of environmental factors, among which water is one of the most critical.

[0003] However, in the field of wild crested wheatgrass seed germination experiments, existing experimental devices and methods have many shortcomings in terms of soil moisture control. Traditional experimental methods, such as using petri dishes or flower pots for seed germination experiments, mainly rely on regular manual watering to maintain soil moisture. However, this method has obvious subjectivity and uncontrollability. It is difficult to keep the time interval and amount of watering precise and consistent, resulting in large fluctuations in soil moisture, which cannot meet the strict requirements of humidity stability in experiments. Moreover, manual operation consumes a lot of time and energy, making it difficult to conduct multiple sets of experiments simultaneously, resulting in low experimental efficiency. While some existing automated irrigation equipment can achieve timed and quantitative water supply, it shows obvious limitations in dealing with the complex and variable humidity requirements in wild crested wheatgrass seed germination experiments. These devices often cannot dynamically adjust according to different stages of seed germination and actual soil moisture conditions, so improvements are needed. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides an experimental device for the germination of wild crested wheatgrass seeds with controllable moisture, which has the advantage of ensuring that the soil always maintains the set humidity.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a moisture-controlled experimental device for the germination of wild crested wheatgrass seeds, comprising:

[0006] The base has a through hole at its bottom end and a partition is fixedly installed inside the top end of the base. The partition is filled with soil and a soil moisture sensor is installed inside the partition and inserted into the soil.

[0007] A water conveying mechanism, wherein the water conveying mechanism is disposed on the outer surface of the base;

[0008] The water delivery mechanism includes a fixed box, the interior of which is fixedly sleeved with the outer surface of the base. A controller is installed on the fixed box. A water delivery pipe is fixedly sleeved inside the fixed box. A drip irrigation hole is opened on the water delivery pipe. A connecting pipe is fixedly sleeved at the right end of the water delivery pipe. A water pump is fixedly installed at the end of the connecting pipe away from the water delivery pipe. A water tank is fixedly sleeved on the outer surface of the connecting pipe. The front of the water tank is fixedly connected to the back of the fixed box. The water pump is located inside the water tank.

[0009] As a preferred embodiment of this utility model, an air humidity sensor and a temperature sensor are fixedly installed inside the fixed box, and a plant growth lamp is fixedly fitted inside the fixed box.

[0010] As a preferred embodiment of this utility model, the front of the fixed box is movably equipped with a box door, the box door is provided with an observation window, and a handle is fixedly installed on the outer surface of the box door.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This experimental device for controlling the germination of wild crested wheatgrass seeds uses a soil moisture sensor to monitor soil moisture in real time. Combined with a controller that presets a humidity threshold, it achieves automated control of the water pump, significantly reducing the range of soil moisture fluctuations, avoiding the impact of improper watering on seed germination, improving the germination rate and the accuracy of experimental data. Furthermore, the controller integrates soil moisture, air humidity, and temperature setting functions, allowing operators to flexibly configure environmental parameters according to experimental needs. At the same time, the air humidity and temperature sensors can collect experimental data in real time. When parameters are abnormal, the controller immediately alarms, reminding operators to intervene in a timely manner, ensuring the stability and controllability of experimental conditions.

[0016] 2. This experimental device for controlling the germination of wild crested wheatgrass seeds with controlled moisture features a controller equipped with a display, which can intuitively present key data such as soil moisture, air humidity, and temperature, as well as the equipment's operating status in real time. This allows experimenters to quickly grasp the experimental progress, simplifying the operation process and improving experimental efficiency. A float water level monitoring structure is installed on the back of the water tank. The float rises and falls with the water level in real time, and the transparent plate provides a convenient way for operators to monitor the water level in the tank. This mechanism requires no power supply, is highly reliable, and has low maintenance costs.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 8 As shown, this utility model provides a moisture-controlled experimental device for the germination of wild crested wheatgrass seeds, comprising:

[0028] The base 1 has a through hole 2 at its bottom end. A partition 3 is fixedly installed inside the top of the base 1. Soil is filled inside the partition 3. A soil moisture sensor 4 is installed inside the partition 3 and inserted into the soil.

[0029] Water delivery mechanism, which is installed on the outer surface of base 1;

[0030] The water delivery mechanism includes a fixed box 5, the interior of which is fixedly sleeved with the outer surface of the base 1. A controller 6 is installed on the fixed box 5. A water delivery pipe 7 is fixedly sleeved inside the fixed box 5. A drip irrigation hole 8 is opened on the water delivery pipe 7. A connecting pipe 9 is fixedly sleeved at the right end of the water delivery pipe 7. A water pump 11 is fixedly installed at the end of the connecting pipe 9 away from the water delivery pipe 7. A water tank 10 is fixedly sleeved on the outer surface of the connecting pipe 9. The front of the water tank 10 is fixedly connected to the back of the fixed box 5. The water pump 11 is located inside the water tank 10.

[0031] Due to the design of the through hole 2, the respiration of the seed roots and the permeability of the soil will be increased. Due to the design of the partition 3, the interior of the base 1 will be divided into multiple independent compartments. Due to the design of the soil moisture sensor 4, the soil moisture can be detected in real time. The working principle of the soil moisture sensor 4 is to determine the water content by measuring the resistance value between soil particles. The higher the soil moisture, the higher the ion concentration and the lower the resistance value; conversely, the lower the moisture, the higher the resistance value. When the soil moisture sensor 4 detects that the soil moisture is too low, it will send a signal to the controller 6. At this time, the controller 6 will send a signal to the water pump 11 to make the water pump 11 run. At this time, the water in the water tank 10 will flow into the connecting pipe 9. Then, this water will flow into the water delivery pipe 7 through the connecting pipe 9 and drip into the soil through the drip irrigation hole 8. When the soil moisture reaches the preset value of the soil moisture sensor 4, the soil moisture sensor 4 will send a signal to the controller 6 again. At this time, the controller 6 will control the water pump 11 to stop running.

[0032] The fixed box 5 is equipped with an air humidity sensor 12 and a temperature sensor 13, and a plant growth lamp 22 is fixedly connected inside the fixed box 5.

[0033] The design of the air humidity sensor 12 and the temperature sensor 13 enables real-time monitoring of the air humidity and temperature inside the device, while the design of the plant growth lamp 22 provides illumination for plant growth.

[0034] The fixed box 5 has a movable door 14 on its front, an observation window on the door 14, and a handle 15 fixedly installed on the outer surface of the door 14.

[0035] The design of the handle 15 makes it easy for the operator to rotate the box door 14. When the box door 14 is rotated, the inside of the fixed box 5 can be opened or closed. Since the box door 14 is equipped with an observation window, it is easy for the operator to observe the seed germination.

[0036] The top of the water tank 10 is fixedly connected to a water inlet pipe 16, and a valve 17 is installed on the water inlet pipe 16.

[0037] The design of the inlet pipe 16 allows water to be added to the water tank 10, and the design of the valve 17 makes it easy for operators to control the opening and closing of the inlet pipe 16.

[0038] A fixing block 18 is fixedly installed on the back of the water tank 10, and a transparent plate 19 is fixedly installed inside the fixing block 18.

[0039] The design of the transparent panel 19 makes it easy for operators to observe the water level inside the water tank 10.

[0040] The fixed block 18 has a vertical shaft 20 fixedly installed inside, and a float 21 is movably sleeved on the outer surface of the vertical shaft 20.

[0041] Due to the design of the float 21, it can move up and down along the outer surface of the vertical axis 20 as the water level changes. The operator can judge the water level inside the water tank 10 by observing the height of the float 21, so as to determine whether water needs to be added to the water tank 10.

[0042] Working principle and usage process of this utility model:

[0043] When conducting a seed germination experiment, the operator first places the seeds in the soil. Then, the operator pulls handle 15 to rotate the two chamber doors 14 in opposite directions. The inside of the fixed chamber 5 closes as the two chamber doors 14 rotate. Since the chamber doors 14 have observation windows, the operator can easily observe the inside of the device. Next, the operator presses the buttons on the controller 6 to set the soil moisture, air humidity, and air temperature values. Because the controller 6 has a display screen, it can visually display the various values ​​inside the experimental device. When the humidity and temperature inside the device are higher or lower than the set values, the air humidity sensor 12 and the temperature sensor 12 will activate. Sensor 13 sends a signal to controller 6, which then issues an alarm to attract operators to check and handle the situation. When the soil moisture is too low, soil moisture sensor 4 sends a signal to controller 6, which in turn sends a signal to water pump 11. At this point, water pump 11 starts running, causing water inside water tank 10 to flow into connecting pipe 9. This water then flows through connecting pipe 9 into water delivery pipe 7 and subsequently drips into the soil through drip irrigation hole 8. When the soil moisture reaches the preset value of soil moisture sensor 4, soil moisture sensor 4 sends a signal to controller 6 again, causing water pump 11 to stop running. This achieves the function of ensuring that the soil always maintains the set moisture level.

[0044] As the soil is continuously drip-irrigated, the water level inside the water tank 10 will gradually decrease. Due to the design of the float 21, it can change with the water level. When the water level inside the water tank 10 decreases, the float 21 will move downward along the outer surface of the vertical axis 20. Due to the design of the transparent plate 19, it is easy for the operator to observe the position of the float 21. When the float 21 is low, it indicates that the water level inside the water tank 10 is critically low. At this time, the operator can open the valve 17 to allow the water inlet pipe 16 to add water into the water tank 10, thus realizing the function of making it easy for the operator to observe the water level inside the water tank 10 and add water to the water tank 10 in a timely manner.
