Abstract
Description
Technical Field
[0001] The embodiments of this disclosure relate to the field of environmental monitoring technology, and more specifically, to a soil sample dehumidifier for environmental monitoring. Background Technology
[0002] Environmental monitoring refers to the regular or continuous monitoring and analysis of various elements in the natural environment using scientific methods. Its aim is to assess environmental quality, identify pollution sources, and provide data support for environmental protection. The monitoring targets include air, water, soil, noise, and radiation, covering multiple indicators such as physical, chemical, and biological data. Modern environmental monitoring combines remote sensing, sensors, and IoT technologies to achieve real-time and precise monitoring. It is widely used in areas such as industrial emission supervision, ecological protection, and public health. Through data analysis, environmental monitoring can provide early warnings of pollution risks, guide the formulation of environmental governance policies, and contribute to sustainable development.
[0003] In existing technologies, operators often collect soil samples and use dehumidifiers to remove moisture from the soil samples during environmental testing. However, while existing dehumidifiers have basic dehumidification functions, they often result in thick soil buildup in some areas when soil samples are placed inside. This hinders subsequent drying and dehumidification, leading to uneven drying between the soil at the edges and the soil piled in the middle. This affects subsequent environmental testing and results in inaccurate data. Therefore, improvements are needed. Utility Model Content
[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide a soil sample dehumidifier for environmental testing, which solves the technical problem of uneven drying in the prior art.
[0005] According to one aspect, at least one embodiment of this disclosure provides a soil sample dehumidifier for environmental testing, including a housing, a movable frame movably sleeved on the outer surface of the housing, a support base fixedly connected to the right side of the movable frame, a first motor fixedly installed inside the support base, a rotating shaft fixedly sleeved at the other end of the output shaft of the first motor, a rotating rod fixedly sleeved at the other end of the rotating shaft, a sleeve rod movably connected to the outer surface of the rotating rod, a connecting rod fixedly connected to the left side of the sleeve rod, and a push plate fixedly connected to the other end of the connecting rod through the movable frame and extending into the interior of the movable frame, the outer surface of the push plate movably connected to the inner surface of the movable frame.
[0006] As a preferred embodiment of this disclosure, the inner cavity of the movable frame is fixedly connected to a placement plate, and the bottom of the placement plate is fixedly connected to a protrusion, which is made of polyoxymethylene.
[0007] As a preferred technical solution of this disclosure, a rectangular plate is fixedly connected to the bottom of the inner cavity of the outer shell, a second motor is fixedly connected to the left side of the rectangular plate, a threaded rod is fixedly sleeved at the other end of the output shaft of the second motor, the other end of the threaded rod passes through the rectangular plate and extends into the interior of the rectangular plate and is threadedly sleeved with a sliding block, a limit block is fixedly connected to the bottom of the sliding block, and the outer surface of the limit block is movably connected to the bottom of the inner cavity of the outer shell.
[0008] As a preferred technical solution of this disclosure, a hollow plate is fixedly connected to the back of the sliding block, and a rotating plate is movably connected inside the hollow plate.
[0009] As a preferred technical solution of this disclosure, a vertical plate is fixedly connected to the bottom of the inner cavity of the outer shell, and a rotating rod is movably sleeved inside the top of the vertical plate, with the outer surface of the rotating rod being fixedly sleeved inside the rotating plate.
[0010] As a preferred technical solution of this disclosure, the other end of the rotating rod passes through the vertical plate and extends to the outside of the vertical plate and is fixedly sleeved with a cam, the top of the cam being movably connected to the bottom end of the protrusion.
[0011] As a preferred technical solution of this disclosure, a hot air blower is fixedly connected to the top of the outer shell, and a connecting pipe and a fixing pipe are fixedly connected to the front and rear sides of the hot air blower, respectively. A filter screen is threaded into the internal thread of the fixing pipe.
[0012] As a preferred technical solution of this disclosure, the other end of the connecting pipe penetrates through the outer shell and extends into the interior of the outer shell and is fixedly sleeved with the interior of the outer shell, and the bottom end of the connecting pipe is fixedly connected to an air outlet pipe.

[0014] As a preferred technical solution of this disclosure, a closed plate is hinged to the inside of the front of the outer shell, and an observation window is fixedly installed inside the closed plate.
[0015] The beneficial effects of the embodiments disclosed herein are as follows:
[0016] 1. This disclosure incorporates a rotating shaft, a rotating rod, a sleeve rod, a connecting rod, and a push plate. When the first motor starts running, the rotating shaft drives the rotating rod to rotate, which in turn pushes the sleeve rod, causing the sleeve rod to move horizontally to the left under the limiting action of the movable frame. Finally, the push plate moves horizontally to the left along the inner cavity of the movable frame, guiding the soil samples piled on top of the placement plate to a uniform height through the guiding action of the inclined surface on the push plate. This achieves uniform accumulation of the soil samples and avoids uneven drying between the soil at the edges and the soil piled in the middle.
[0017] 2. This disclosure incorporates a hollow plate, a rotating plate, a rotating rod, a cam, and a protrusion. When the second motor starts running, the threaded rod rotates. At this time, the sliding block drives the limiting block to move horizontally to the left under the limiting action of the outer shell, causing the hollow plate to move synchronously. This causes the hollow plate to press and push the rotating plate, which in turn causes the rotating rod and cam to rotate. The cam then presses and pushes the protrusion, ultimately causing the protrusion to drive the placement plate and the movable frame to vibrate vertically up and down inside the outer shell, thereby turning over the soil at the bottom and improving drying efficiency.

Detailed Implementation
[0025] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.
[0026] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0027] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.
[0028] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0029] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.
[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0031] like Figures 1-5 As shown, a soil sample dehumidifier for environmental testing according to an embodiment of the present disclosure is illustrated, including a housing 1. A movable frame 2 is movably sleeved on the outer surface of the housing 1. A support base 3 is fixedly connected to the right side of the movable frame 2. A first motor 4 is fixedly installed inside the support base 3. A rotating shaft 5 is fixedly sleeved at the other end of the output shaft of the first motor 4. A rotating rod 6 is fixedly sleeved at the other end of the rotating shaft 5. A sleeve rod 7 is movably connected to the outer surface of the rotating rod 6. A connecting rod 8 is fixedly connected to the left side of the sleeve rod 7. The other end of the connecting rod 8 passes through the movable frame 2 and extends into the interior of the movable frame 2 and is fixedly connected to a push plate 9. The outer surface of the push plate 9 is movably connected to the inner surface of the movable frame 2.
[0032] Due to the design of the support base 3, the first motor 4 is enclosed, thereby preventing external dust, moisture and other impurities from entering the interior of the first motor 4 and affecting its normal operation. This improves the service life of the first motor 4 and ensures the stability of the equipment during long-term operation.
[0033] In some examples, the inner cavity of the movable frame 2 is fixedly connected to a placement plate 11, and the bottom of the placement plate 11 is fixedly connected to a protrusion 22, which is made of polyoxymethylene.
[0034] Polyoxymethylene (POM) has the advantages of high rigidity and low coefficient of friction, as well as excellent wear resistance, fatigue resistance and low noise generated by friction, thus ensuring long-term stable operation of equipment.
[0035] In some examples, a rectangular plate 12 is fixedly connected to the bottom of the inner cavity of the outer shell 1, a second motor 13 is fixedly connected to the left side of the rectangular plate 12, a threaded rod 14 is fixedly sleeved at the other end of the output shaft of the second motor 13, the other end of the threaded rod 14 passes through the rectangular plate 12 and extends into the interior of the rectangular plate 12 and is threadedly sleeved with a sliding block 15, a limit block 16 is fixedly connected to the bottom of the sliding block 15, and the outer surface of the limit block 16 is movably connected to the bottom of the inner cavity of the outer shell 1.
[0036] Due to the limiting effect of the limiting block 16, the sliding block 15 can only move horizontally left and right.
[0037] In some examples, a hollow plate 17 is fixedly connected to the back of the sliding block 15, and a rotating plate 18 is movably connected inside the hollow plate 17.
[0038] The inner surface of the hollow plate 17 is smooth, which makes the movement of the rotating plate 18 inside the hollow plate 17 smoother.
[0039] In some examples, a vertical plate 19 is fixedly connected to the bottom of the inner cavity of the outer shell 1, and a rotating rod 20 is movably sleeved inside the top of the vertical plate 19. The outer surface of the rotating rod 20 is fixedly sleeved inside the rotating plate 18.
[0040] The outer surface of the rotating rod 20 is smooth, which makes the movement of the rotating rod 20 inside the vertical plate 19 smoother.
[0041] In some examples, the other end of the swivel 20 passes through the vertical plate 19 and extends to the outside of the vertical plate 19 and is fixedly sleeved with a cam 21, the top of the cam 21 being movably connected to the bottom end of the protrusion 22.
[0042] The cam 21 is made of low carbon steel and undergoes surface hardening treatment, such as carburizing or quenching, which can significantly improve the hardness of the cam 21 and prevent scratches on the surface of the cam 21 when it comes into direct contact with the protrusion 22.
[0043] In some examples, a hot air blower 23 is fixedly connected to the top of the housing 1, and a connecting pipe 24 and a fixing pipe 25 are fixedly connected to the front and rear sides of the hot air blower 23, respectively. A filter screen 27 is threaded into the inside of the fixing pipe 25.
[0044] The air will first pass through the filter screen 27 to filter out dust and impurities before entering the hot air blower 23 and being heated.
[0045] In some examples, the other end of the connecting pipe 24 passes through the housing 1 and extends into the interior of the housing 1 and is fixedly connected to the interior of the housing 1, and the bottom end of the connecting pipe 24 is fixedly connected to the air outlet pipe 26.
[0046] The air heated by the hot air blower 23 will be blown out through the air outlet 26. The open design of the air outlet 26 reduces the air velocity, increases the heating area, and avoids local overheating.
[0047] In some examples, a second filter screen 28 is threaded onto the top of the housing 1, and foot supports 10 are fixedly installed at the four corners of the bottom of the housing 1.
[0048] The design of four feet 10 prevents the bottom of the outer shell 1 from directly contacting the ground, thus achieving the function of moisture and rust prevention.
[0049] In some examples, a closure plate 29 is hinged to the inside of the front of the housing 1, and an observation window 30 is fixedly installed inside the closure plate 29.
[0050] Operators can observe the drying and accumulation status of the soil sample located inside the placement plate 11 through the observation window 30 to determine when to start and stop the first motor 4 and the second motor 13.
[0051] The working principle and usage process of this disclosure are as follows:
[0052] Rotate to open the observation window 30, place the soil sample to be dried on top of the placement plate 11, and start the hot air blower 23. The hot air blower 23 draws in outside air through the fixed pipe 25, and after passing through the first filter screen 27 and being heated by the hot air blower 23, the air is discharged into the interior of the outer shell 1 through the connecting pipe 24 and the air outlet pipe 26. At this time, the dehumidification and drying operation will be carried out. Then, start the first motor 4, so that the rotating shaft 5 drives the rotating rod 6 to rotate, and then the rotating rod 6 squeezes and pushes the sleeve rod 7. The sleeve rod 7 drives the connecting rod 8 to move horizontally to the left under the limiting action of the movable frame 2. Finally, the push plate 9 moves horizontally to the left along the inner cavity of the movable frame 2, and pushes the soil sample piled on the top of the placement plate 11 and the soil sample piled at a high height to the same horizontal height through the guiding action of the inclined surface on the push plate 9, so as to achieve uniform accumulation of soil sample and avoid uneven drying of soil at the edge and soil piled in the middle.
[0053] After the pusher plate 9 flattens the soil sample, the second motor 13 is started, causing the threaded rod 14 to rotate. At this time, the sliding block 15 will drive the limiting block 16 to move horizontally to the left under the limiting action of the outer shell 1, and cause the hollow plate 17 to move synchronously. Then, the hollow plate 17 squeezes and pushes the rotating plate 18. At this time, the rotating plate 18 drives the rotating rod 20 and the cam 21 to rotate, and the cam 21 squeezes and pushes the protrusion 22. Finally, the protrusion 22 drives the placement plate 11 and the movable frame 2 to vibrate vertically up and down inside the outer shell 1, realizing the function of turning over the soil at the bottom and improving the drying efficiency.
[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
