Detailed Implementation

[0019] Please see Figures 1-4 In this embodiment of the invention, a soil fertility monitoring device for vegetable cultivation includes a monitoring instrument body 1 and a screw cap 3 engaged with the upper end of the monitoring instrument body 1. A protective tube 6, a first insertion tube 12, and a second insertion tube 13 are arranged in a ring at the lower end of the monitoring instrument body 1. Several mounting slots 4 are formed on the upper inner side of the monitoring instrument body 1. A display control screen 2 is embedded in the outer side of the monitoring instrument body 1, through which various monitored indicators can be displayed. A sampling tube 5 is installed inside each mounting slot 4. A temperature and humidity sensor 11 is installed at the lower end of the second insertion tube 13. The temperature and humidity sensor 11 can monitor the humidity and temperature in the soil to determine the soil moisture content and the temperature of the growing environment for vegetables; the lower end of the insertion tube 12 is equipped with a conductivity sensor 10, which can monitor the soil conductivity to determine the water-soluble salt content in the soil; the lower end of the protective tube 6 is engaged with a filter tube 7, and the lower end of the filter tube 7 is engaged with a water collection head 9, so that water in the soil can seep into the filter tube 7 and be stored in the water collection head 9; the sampling mechanism 8 is installed inside the monitoring instrument body 1, the protective tube 6, the filter tube 7, and the water collection head 9.

[0020] exist Figure 2 and Figure 3 In the sample tube 5, there is a sample tube body 51. A tube plug 54 is embedded in the upper end of the sample tube body 51, and a water inlet 52 is provided at the lower end of the sample tube body 51. A check valve 53 is installed on the water inlet 52. Water in the soil is collected into the sample tube body 51 through the water inlet 52. The check valve 53 can prevent water in the sample tube body 51 from flowing down from the water inlet 52. After the sample tube 5 is pulled out from the mounting groove 4, the tube plug 54 is opened, and the collected water sample can be poured out from the sample tube body 51.

[0021] exist Figure 2 and Figure 4The sampling mechanism 8 includes a miniature water pump 81. An outlet pipe 84 is fixedly connected to the output end of the miniature water pump 81, and an inlet pipe 83 is fixedly connected to the input end of the miniature water pump 81. A five-way connector 87 is fixedly connected to the upper end of the outlet pipe 84. Several branch pipes 86 are fixedly connected to the outside of the five-way connector 87. Each branch pipe 86 and the upper end of the five-way connector 87 are fixedly connected to an outlet 85. A storage battery is installed inside the monitoring instrument body 1, which provides power to the display control panel 2, the miniature water pump 81, and the solenoid valve 88. The display control panel 2 can send commands to the miniature water pump 81 and the solenoid valve 88 to control their opening and closing. A filter head 82 is fixedly connected to the lower end of the inlet pipe 83. The filter head 82 is located inside the water collection pipe head 9, and the filter head 82 can filter the water collection pipe head. The water in the 9 is filtered again to avoid excessive solid impurities in the water, which could cause pipe blockage. The upper end of the outlet 85 is embedded in the corresponding inlet 52. Each outlet 85 is equipped with a solenoid valve 88. By opening the solenoid valve 88, the water output of the corresponding outlet 85 can be controlled, so that water in the soil can be pumped into the corresponding sampling tube 5 at different times. After the water in the sampling tube 5 is taken out, it can be sent to the laboratory for precise analysis to determine the fertility of the soil. The inlet pipe 83 is embedded in the inner side of the protective pipe 6, the filter tube 7 and the water collection pipe head 9 in sequence.

When the sampling tube 5 is inserted into the mounting groove 4, the inlet 52 is sleeved on the corresponding outlet 85, so that the sampling mechanism 8 is connected to the sampling tube 5.

[0022] The working principle of this utility model is as follows: When it is necessary to monitor the fertility of the soil, the water collection pipe head 9, the insertion tube 12 and the insertion tube 2 13 are inserted into the soil to a certain depth. The humidity and temperature in the soil can be monitored by the temperature and humidity sensor 11 to determine the soil moisture content and the temperature of the growing environment of vegetables. The conductivity sensor 10 can monitor the conductivity in the soil to determine the content of water-soluble salts in the soil.

[0023] Water in the soil seeps into the filter tube 7 after being filtered and stored in the water collection head 9. When it is necessary to sample and analyze the water in the soil, the micro water pump 81 is turned on. The water in the water collection head 9 is filtered again by the filter head 82 and then enters the inner side of the inlet pipe 83, the micro water pump 81 and the outlet pipe 84 in sequence. After being diverted by the five-way connector 87, it enters the corresponding diversion pipe 86. After the corresponding solenoid valve 88 is turned on, the water enters the sampling tube body 51 through the outlet 85 and the inlet 52. At different times, by turning on different solenoid valves 88, water samples at different times can be collected into the corresponding sampling tubes 5.

[0024] By unscrewing the screw cap 3 counterclockwise, the sampling tube 5 can be taken out from the mounting slot 4 and sent into the laboratory for precise analysis of its components.

[0025] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
