Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer production technology, and in particular to a portable sensor and its housing for detecting moisture in fermentation materials. Background Technology

[0002] Organic fertilizer is a type of fertilizer with excellent environmental protection and topdressing effects, obtained through the microbial decomposition of biological organic matter, namely animal excrement and plant straw. During the fermentation process, to ensure effective fermentation, the humidity and temperature of the compost pile are crucial. Currently, frequency domain reflectance (FDR) sensors are used for humidity detection in compost piles. These sensors utilize the principle of electromagnetic pulses, measuring the apparent dielectric constant of the compost pile based on the frequency of electromagnetic wave propagation in the medium, thereby determining the volumetric moisture content. These humidity sensors typically consist of three probes and a display screen for showing the humidity. However, when measuring compost humidity, the probes need to be inserted into the compost pile. Currently, commonly used probes are housed within a sealed enclosure, which presents problems such as inconvenience in holding and inserting them. Furthermore, the display screen can be damaged by drops during use. Finally, cleaning the probes after testing is inconvenient, affecting subsequent testing operations. Utility Model Content

[0003] This invention provides a portable sensor and its housing for detecting moisture in fermentation materials, which overcomes the shortcomings of the prior art and solves the problems of poor protection for the display screen and inconvenience in inserting probes into the material pile, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] On the one hand, a portable sensor housing for detecting moisture in fermentation materials is provided, including a housing with an elongated structure. The upper wall of the housing has an embedded display screen, and the upper end of the housing has multiple buttons. A connecting wire is connected to the end of the housing, and a sealing head is connected to the connecting wire. The other end of the sealing head has at least two probes. One end of the lower wall of the housing has a lower convex shell with at least a pair of insertion holes. The probes are inserted into the insertion holes. The sealing head is positioned on the lower side of the housing, which is convenient for the operator to push and move, thus facilitating the insertion of the probes into the material pile. Secondly, after moisture detection, the probes can be pulled backward to avoid deformation during transfer. At the same time, the insertion holes can be used to scrape off any solid residue remaining on the outer periphery of the probes, which facilitates moisture detection at different locations in the material pile.

[0006] Furthermore, grooves are formed on both sides of the shell to facilitate gripping by the operator.

[0007] Furthermore, a rubber sleeve is attached to the outer end of the inner wall of the socket. The rubber sleeve is fitted onto the probe, and the effect of scraping off impurities is improved by the rubber sleeve tightly gripping the probe.

[0008] Furthermore, a concave cover is provided on one end of the housing located on the display screen. Horizontal holes are provided on both sides of the concave cover, and limiting screws are inserted into the horizontal holes. The inner ends of the limiting screws are threaded to both sides of the housing. The concave cover is placed on the display screen to protect it and prevent the display screen from breaking due to falling or other reasons.

[0009] Furthermore, racks are formed on both sides of the concave cover, with gears meshing on the racks. A rotating shaft passes through the gears, and the inner end of the rotating shaft is threaded to the housing. A lower rack also meshes on the gear, and one end of the lower rack has a side plate. The lower end of the side plate is installed on the encapsulation head by screws. A groove is formed on the inner wall of the side plate, and a transverse strip is provided in the groove. The transverse strip is located on the side wall of the housing. In this way, when testing, the concave cover can be eliminated from obstructing the display screen, and the probe can also be extended, making it easier to insert the probe into the material pile. When the instrument is not in use, the probe is in a retracted state to prevent deformation due to misoperation, and the concave cover also protects the display screen.

[0010] Furthermore, a pressure plate is provided at the outer end of the rotating shaft. The inner wall of the pressure plate abuts against the outer end of the gear. A protrusion is formed on the pressure plate. The rotation of the gear can be locked by rotating the shaft to prevent the concave cover or probe from moving, thereby improving the protection effect and ensuring that the probe will not retract during insertion.

[0011] On the other hand, a portable sensor for detecting moisture in fermentation materials is provided, including a portable sensor housing for detecting moisture in fermentation materials.

[0012] The advantages of the above technical solution are:

[0013] This invention firstly facilitates the insertion of probes during testing, secondly enables the cleaning and protection of probes, and finally protects the display screen. Attached Figure Description

[0019] Example 1

[0020] like Figures 1-4 As shown, a portable sensor housing for detecting moisture in fermentation materials is provided, including a housing 1. The housing 1 has an elongated structure, with grooves 100 formed on both sides. A display screen 10 is embedded in the upper wall of the housing 1. Multiple buttons 11 are provided at the end of the upper wall of the housing 1. A connecting line 12 is connected to the end of the housing 1, and a sealing head 13 is connected to the connecting line. At least two probes 14 are provided at the other end of the sealing head 13. A lower convex shell 15 is provided at one end of the lower wall of the housing 1. At least one pair of insertion holes 16 are opened on the lower convex shell 15. The probes 14 are respectively inserted into the insertion holes 16. A rubber sleeve is attached to the outer end of the inner wall of the insertion hole 16 and the rubber sleeve is fitted onto the probes 14.

[0021] A concave cover 20 is provided on one end of the housing 1 located on the display screen 10. A transverse hole 21 is provided on both sides of the concave cover 20. A limiting screw 2 passes through the transverse hole 21. The inner end of the limiting screw 2 is threaded to both sides of the housing 1. The concave cover 20 is provided on the display screen 10 to protect the display screen 10.

[0022] The concave cover 20 has racks 22 formed on both sides, and gears 23 mesh on the racks 22. A rotating shaft passes through the gears 23, and the inner end of the rotating shaft is connected to the housing 1 by a thread. A lower rack 26 also meshes on the gears 23. A side plate 28 is provided at one end of the lower rack 26. The lower end of the side plate 28 is installed on the encapsulation head 13 by a screw. A groove is opened on the inner wall of the side plate 28, and a transverse strip 27 is provided in the groove. The transverse strip 27 is provided on the side wall of the housing 1. A pressure plate 24 is provided at the outer end of the rotating shaft. The inner wall of the pressure plate 24 abuts against the outer end of the gear 23. A protruding plate 25 is formed on the pressure plate 24.

[0023] In this embodiment, when the operator uses the portable sensor with the housing for detecting the moisture content of fermentation materials, the operator first rotates the shaft to release the pressure of the pressure plate 24 on the gear 23. Then, the operator pulls the concave cover 20 backward. During the pulling process, the rack 22 acts on the gear 23, causing the gear 23 to rotate. The rotation of the gear 23 will drive the lower rack 26 to move forward. The forward movement of the lower rack 26 will drive the encapsulation head 13 and the probe 14 to move outward until the outer end of the encapsulation head 13 abuts against the inner end of the lower convex shell 15. This makes the probe 14 protrude. When the concave cover 20 moves backward, the display screen 10 will also be exposed. After that, the operator screws the shaft to lock the rotation of the gear 23 through the pressure plate 24. Then, the probe 14 is inserted into the material pile, and the corresponding humidity data is obtained through the display screen 10 on it. After completion, loosen the pivot again to return the concave cover 20 and probe 14 to their original positions. During the repositioning process, the rubber sleeve scrapes away impurities on the outer periphery of probe 14, and the concave cover 20 protects the display screen.
