Technical Field
[0001] The present application relates to the field of plant seedling cultivation, and in particular to a device for detecting temperature and humidity of plant seedling cultivation soil. Background Art
[0002] With the development of gardens, the demand for various ornamental plants is increasing. Conventional wild collection can no longer meet people's various needs. Therefore, more and more places have begun to artificially select and cultivate seedlings of some ornamental plants.
[0003] Since plant seedlings have poor ability to cope with weather changes, the selection and cultivation of plant seedlings are mostly carried out on the culture medium in the greenhouse, which is conducive to artificially controlling the environment in the greenhouse and improving the survival rate of plant seedlings. The temperature and humidity parameters of the culture medium in the greenhouse are a major factor affecting the growth of seedlings. Therefore, in order to improve the survival rate of seedlings, it is necessary to monitor and intervene in the temperature and humidity of the culture medium.
[0004] The culture medium generally used for cultivating plant seedlings is mostly prepared nutrient soil, which is usually made of peat soil or coconut husk as the base material, mixed with a variety of nutrient solutions and decomposed manure. Decomposed manure is rich in microorganisms, which may ferment (continue to decompose) in a suitable temperature and humidity environment in the greenhouse, and the continued decomposition process will cause the temperature and humidity in the soil base to change, ultimately affecting the survival rate of the seedlings. Therefore, it is generally necessary to regularly test and monitor the temperature and humidity in the soil base.
[0005] One detection and monitoring method in the related technology is to manually insert a thermometer and hygrometer into the soil foundation at regular intervals to measure the temperature and humidity data at different depths in the soil foundation. However, the area of a general soil foundation is large, and it takes a lot of time and energy for operators to complete each detection. In addition, since the soil foundation in the same area needs to collect temperature and humidity data at different depths, it is necessary to insert thermometers and hygrometers for detection multiple times in the same area, and the detection efficiency is low.

The track 1 is arranged in the greenhouse and arranged along the length direction of the greenhouse, and the culture soil 4 is divided into a plurality of ridges. The track 1 is placed in the greenhouse and placed and fixed on the ground of the greenhouse along the length direction of each ridge of culture soil 4.

[0038] Reference Figure 4 and Figure 5 After the shell 34 is inserted into the culture soil 4, the sensing needle needs to extend from the through hole 341 on the shell 34. In the initial state, the sensing needle is hidden in the shell 34. Figure 3, a sliding groove 353 is provided on the inner wall of the shell 34, and the sensing needle is inserted into the sliding groove 353, and the sliding groove 353 is connected with the perforation 341. When the inner push component pushes the sensing needle to move, the sensing needle moves along the sliding groove 353. A plurality of mounting holes 362 are provided on the outer wall of the inner push component, and the inner push component includes a push rod 361. The sensing needle is hinged on the outer wall of the push rod 361. The sensing needle is provided with a rotating shaft, which is sleeved in the mounting hole 362. A torsion spring is sleeved on the rotating shaft, one end of the torsion spring is fixed on the rotating shaft, and the other end of the torsion spring is fixed on the inner wall of the mounting hole 362. In the initial state, the sensing needle and the push rod 361 are placed in the shell 34 in a close fit, and the sensing needle is limited by the inner wall of the shell 34. When it is necessary to detect the temperature of the culture soil 4, the sensing needle is pushed by the push rod 361 and moves along the axial direction of the shell 34 until the sensing needle moves to a position facing the perforation 341, and the sensing needle extends from the perforation 341 driven by the torsion spring. The frame 2 is provided with a hydraulic pushing device 363 for pushing the pushing rod 361, and the hydraulic pushing device 363 pushes the pushing rod 361 to move along the axial direction of the housing 34. That is, the power of the pushing rod 361 comes from the hydraulic pushing device 363, and of course, it can also come from any other device that can play a linear pushing role, such as a pneumatic device. The hydraulic pushing device 363 can also be remotely controlled to achieve automatic control, reduce human participation, and improve detection efficiency.
[0039] Of course, the probe bracket 31 in the first embodiment of the detection component can also be retained, and the housing 34 of the detection component in the second embodiment can be fixed on the probe bracket 31. The detection needle 32 in the first embodiment and the sensing needle in the second embodiment are actually temperature and humidity probes for inserting into the culture soil 4 to detect temperature and humidity. In this embodiment, the hydraulic push device 363 can be fixed on the housing 34.
[0040] In this embodiment, when testing, the detection component first remotely controls the outer shell 34 to be inserted into the soil layer of the culture soil 4, and then controls the push rod 361 to move downward. The sensing needle should move to the position of the perforation 341 and extend from the perforation 341 due to the reset action of the torsion spring. A plurality of perforations 341 can be provided on the outer shell 34, and each perforation 341 can correspond to a sensing needle, so that the temperature and humidity at different depths in the culture soil 4 can be tested, and the detection is more convenient.
