Description

Technical Field

[0001] The present invention belongs to the field of agricultural science and technology, and specifically relates to a process and device for preserving and displaying the original state of a soil profile. Background Art

[0002] The preservation of soil profiles in their original state is generally achieved through conventional techniques that keep the original structure and properties of the soil from being destroyed or changed during soil sampling, transportation, storage, and analysis. These techniques are crucial to ensuring the accuracy and reliability of soil analysis results. The common method of preserving soil profiles in their original state is to use instruments to take samples in the field to maintain the original structure of the soil, put the soil into special boxes, disinfect and shape it, and maintain its original profile state. The collected soil samples are stored in a sealed environment to slow down microbial activity and chemical changes. For some analyses, soil samples may need to be dried and sealed to prevent moisture and gas exchange.

[0003] Soil profiles are typically stored and displayed separately. For storage, the boxes are moved to storage boxes, and for display, they are simply placed on a countertop. Because soil profile boxes are heavy, manual storage and display are time-consuming and laborious, and frequent manual handling can easily damage the soil profile structure. Summary of the Invention

[0004] In response to the above problems, the present invention provides a process and device for preserving and displaying the original state of soil profiles. The present invention integrates the preservation and display functions of soil profiles into one system, avoiding the tedious process of separate preservation and display in traditional methods, improving work efficiency and display effects, and realizing the automated operation of preservation and display.

[0005] To achieve the above object, the technical solution adopted by the present invention is: A device for preserving and displaying soil profiles in their original state comprises a display stand, wherein a display rack capable of being raised and lowered is provided within the display stand, and a plurality of display boxes storing soil profiles are arranged in a circular pattern on the display rack; the display rack can automatically rotate when raised to the top of the display stand; and a display screen for displaying soil profile information is provided on the front of the display stand.

[0006] Compared with the prior art, the present invention has the following beneficial effects: This device integrates the preservation and display functions of soil profiles into a single system, avoiding the tedious process of separate preservation and display required in traditional methods and improving work efficiency. The device achieves automated operation through a motor-driven lifting plate and rotating frame, reducing the time and labor required for manual handling and operation, and improving the convenience of display. It also reduces vibrations to the soil, ensuring the stability of the soil profile structure. Using a transparent square sealed box, which rotates on a display stand, it can display multiple soil profile structures at once, facilitating observation of the structure and characteristics of the soil profile while enhancing the display effect, making it suitable for educational and scientific research purposes.

[0007] As a further improvement of the above solution, the display box is a transparent square sealed box body, which stores the soil profile structure inside and is shaped by a setting liquid; an upper positioning hole is provided on the top of the display box, and a lower positioning hole is provided on the bottom, and a heat-conducting rod is provided in the lower positioning hole and extends deep into the display box.

[0008] The technical benefits of these improvements are as follows: The transparent, square, sealed box allows for intuitive visualization of the soil profile, facilitating observation and educational demonstrations. Using a setting fluid to set the soil profile, the original state of the soil profile is preserved over time, minimizing physical and chemical changes. The upper and lower positioning holes at the top and bottom, combined with heat-conducting rods, allow for quick positioning and securement of the display box. The rods also monitor the soil profile temperature, making it suitable for display or storage environments requiring temperature control.

[0009] As a further improvement of the above solution, the display stand includes a base, a rotating disk is provided on the base, and a mounting bracket for mounting a display box is provided on the rotating disk; a top plate is provided on the top of the mounting bracket, and a hollow shaft is provided vertically in the center of the inside; a lighting lamp is provided on the top plate; a mounting groove for placing the display box is provided on the side of the mounting bracket; a positioning rod is provided on the bottom surface of the mounting groove, and a positioning hole is provided on the top surface; a positioning sensor for detecting the rotation angle of the rotating disk is provided on the base.

[0010] The technical benefits of these improvements are as follows: The display stand's rotating disc and mounting bracket design allow the display box to be easily rotated to the front of the display stand, improving display efficiency. Lights on the top panel provide excellent illumination, making soil profile details more clearly visible. The mounting slots, positioning rods, and positioning holes on the side of the mounting bracket ensure stable installation and quick positioning of the display box.

[0011] As a further improvement of the above solution, the inner cavity of the mounting frame constitutes a wiring cavity for installing wires; a conductive slip ring is provided between the rotating disk and the base; one end of the conductive slip ring is connected to the installed inner cavity wire, and the other end is connected to the conductive contact on the outer wall of the base; and a power supply contact electrically connected to the conductive contact is provided on the display stand.

[0012] The technical effect of this improvement is that the conductive slip ring design allows the rotating disk to continue to be powered while it rotates, ensuring the continuous operation of lighting and other electronic equipment. The electrical connection between the power supply contacts and the conductive contacts on the display stand provides a simple and reliable power connection method.

[0013] As a further improvement of the above-mentioned scheme, the inner cavity of the display stand is divided into an upper storage cavity and a lower transmission cavity by a partition; the display rack is located in the storage cavity; a screw rod is provided in the transmission cavity, a connecting rod is provided at the upper end of the screw rod, and the lower end is connected to the motor; the upper end of the connecting rod is connected to the one-way rotating wheel after passing through the partition; the one-way rotating wheel is provided in the hollow shaft; the bottom surface of the one-way rotating wheel is provided with an annular tooth surface; the bottom of the hollow shaft is provided with a face gear ring; the annular tooth surface cooperates with the face gear ring; a lifting plate is provided on the screw rod; a guide shaft is provided at the bottom of the display rack, and the guide shaft passes through the partition and is connected to the lifting plate.

[0014] The technical effect of the above improvements is that the partition divides the display stand's interior into a storage chamber and a transmission chamber, enabling the display stand to be raised and lowered and the display boxes to be stored. The coordinated use of the screw rod and motor ensures smooth raising and lowering of the display stand, reducing operating noise and mechanical wear.

[0015] As a further improvement of the above solution, the one-way rotating wheel includes a first ratchet connected to the connecting rod, a rotatable outer wheel is coaxially arranged outside the first ratchet, and an annular tooth surface is arranged under the outer wheel; the pawl of the first ratchet is arranged on the inner side of the outer wheel.

[0016] The technical effects of these improvements are as follows: the one-way rotating wheel design ensures that the display stand can only rotate in one direction, preventing the display boxes from being misplaced due to reverse rotation. The design of the lifting plate allows the display stand to be raised and lowered smoothly. At the same time, the design of the locking slot and rocker plate allows the lifting plate to be locked after reaching the top, ensuring the stability of the display stand in the display position.

[0017] As a further improvement of the above scheme, the lifting disk includes a nut disk connected to the screw rod, a rotatable second ratchet is coaxially arranged on the nut disk, and a rotatable one-way disk is arranged outside the second ratchet; the lower end of the guide shaft is connected to the one-way disk; the pawl of the second ratchet is arranged on the inner side of the one-way disk; the nut disk is provided with a slot that cooperates with the rocker; the one-way disk is provided with a switch hole, and a rocker that can be flipped up and down is installed in the switch hole through a pin shaft, and a torsion spring is provided between the rocker and the pin shaft, and the torsion spring makes the rocker snap into the slot when it is reset; a top rod is provided on the bottom surface of the partition to drive the rocker to flip; after the lifting disk rises to the top, the top rod drives the rocker to tilt, so that the rocker is separated from the slot.

[0018] The technical effect of the above improvements is: through the carefully designed lifting plate and one-way plate structure, precise control and safe locking of the display box are achieved. The nut on the lifting plate is connected to the screw rod, ensuring the stability and precise positioning of the display box during the lifting process. The cooperation between the second ratchet and the one-way plate provides a reliable locking mechanism, preventing the display box from accidentally sliding when not in operation, thereby enhancing the safety of use. The cooperation between the seesaw and the slot and the design of the top rod driving the seesaw to flip enable the display box to be automatically unlocked and quickly displayed after the lifting plate reaches the top, reducing manual intervention and improving display efficiency. In addition, the torsion spring ensures that the seesaw can be stably inserted into the slot when in the reset state, enhancing the safety of operation and preventing the display box from accidentally falling off due to misoperation. The entire design not only improves the degree of automation of the display and optimizes the user experience, but also makes the structure more compact and easier to maintain, thereby significantly improving the display efficiency and convenience of operation.

[0019] As a further improvement of the above solution, at least two switch holes are arranged in a ring shape on the one-way disk.

[0020] The technical effect of the above improvement is that the multiple switch holes provided on the one-way disk provide a flexible connection method, and different switch holes can be selected for connection as needed.

[0021] This design increases the adaptability and flexibility of the device, allowing for quick adjustments based on actual display needs.

[0022] As a further improvement of the above solution, an ultraviolet lamp is provided on the side of the storage cavity.

[0023] The technical effect of the above improvements is that the installation of ultraviolet lamps provides an effective disinfection method, which can regularly disinfect the display box in the storage chamber, maintaining the hygiene and safety of soil profile samples. This regular disinfection helps prevent microbial contamination and extend the shelf life of soil profile samples.

[0024] A process for preserving and displaying a soil profile in its original state, using a device for preserving and displaying a soil profile in its original state, comprises the following steps: Place the soil profile material into a display box, inject a setting agent, seal the display box, and perform irradiation sterilization; Place the display box into the installation slot, fit the lower positioning hole on the bottom of the display box into the positioning protrusion, and then pass the bolts through the fixing holes and connect them to the upper positioning holes to secure the display box. When the soil profile needs to be displayed, the lifting plate is driven to rise by the screw rod, and the lifting plate drives the display frame to rise to the display table. The motor stops rotating and the soil profile information is displayed on the display screen. When different soil profiles need to be displayed, the motor continues to rotate, driving the connecting rod to rotate, the connecting rod drives the one-way rotating wheel to rotate, the one-way rotating wheel drives the rotating disk to rotate, and thus drives the display stand to rotate. The positioning sensor senses the rotation angle of the display stand, so that the display box on the other side of the display stand faces the front of the display stand; When the soil profile is no longer needed to be displayed, the screw rotates in the opposite direction, the lifting plate descends, and the display rack is driven down into the storage cavity for storage. At the same time, the top plate of the display rack seals the top surface of the storage cavity. When the display box needs to be disinfected regularly, the ultraviolet lamp is started to perform light disinfection on the display box in the storage cavity. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] In order to enable those skilled in the art to better understand the technical solution, the present invention is described in detail below in conjunction with embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0043] like Figure 1-16 As shown, the specific solution of this embodiment is: a device for preserving and displaying the original state of soil profiles, including a display stand 4, a display rack 2 that can be raised and lowered is provided inside the display stand 4, and a plurality of display boxes 1 storing soil profiles are distributed in a ring shape on the display rack 2; the display rack 2 can automatically rotate when it is raised to the top of the display stand 4; a display screen 3 for displaying soil profile information is provided on the front of the display stand 4.

[0044] Specifically, the display stand 4 is constructed as a 0.5-meter-long, 0.5-meter-wide, and 1-1.5-meter-high display stand 4 with a sloping front surface and an embedded high-definition display screen 3. The display stand 2 can be raised and lowered within the inner cavity 5 of the display stand 4. When display is needed, the display stand 2 rises to the top of the display stand 4. The display stand 2 can be rotated and positioned at a fixed angle. The display box 1 is mounted on the side of the display stand 2 for easy display.

[0045] like Figure 5-6As shown, as a preferred embodiment of the above embodiment, the display box 1 is a transparent square sealed box body, in which the soil profile structure is preserved and shaped by a setting liquid; an upper positioning hole 101 is provided on the top of the display box 1, and a lower positioning hole 103 is provided on the bottom. A heat-conducting rod 102 is provided in the lower positioning hole 103 and extends deep into the display box 1.

[0046] After the soil profile structure is stored in the display box 1, the setting liquid is generally a solidifiable transparent glue; the excavated soil is first placed in its original state into the display box 1 of the same size and then irradiated and sterilized, and then the setting liquid is added to set the soil and the soil is sealed in the display box 1.

[0047] Place the display box 1 into the mounting slot 202, aligning the lower positioning hole 103 with the positioning protrusion 206 on the display stand 2. Then, bolt through the fixing hole 205 and secure it to the upper positioning hole 101 of the display box 1. The heat-conducting rod 102 senses the soil temperature inside the display box 1 and transmits it to the positioning protrusion 206, which can be a raised temperature sensor.

[0048] like Figure 8-9 As shown, as a preferred embodiment of the above embodiment, the display stand 2 includes a base 207, a rotating disk 211 is provided on the base 207, and a mounting frame 203 for mounting the display box 1 is provided on the rotating disk 211; a top plate 208 is provided on the top of the mounting frame 203, and a hollow shaft 204 is vertically provided in the center of the inside; a lighting lamp 201 is provided on the top plate 208; a mounting groove 202 for placing the display box 1 is provided on the side of the mounting frame 203; a positioning protrusion 206 is provided on the bottom surface of the mounting groove 202, and a fixing hole 205 is provided on the top surface; a positioning sensor 209 for detecting the rotation angle of the rotating disk 211 is provided on the base 207.

[0049] like Figure 2-3 As shown, as a preferred embodiment of the above embodiment, the inner cavity 5 of the mounting frame 203 constitutes a wiring cavity for installing wires; a conductive slip ring 210 is provided between the rotating disk 211 and the base 207; one end of the conductive slip ring 210 is connected to the wires installed in the inner cavity 5, and the other end is connected to the conductive contacts on the outer wall of the base 207; and a power supply contact 15 electrically connected to the conductive contact is provided on the display stand 4.

[0050] Specifically, the shape of the base 207 matches the shape of the installation cavity and can be raised and lowered within the installation cavity. The rotating disk 211 is embedded in the base 207 and can rotate, and the mounting bracket 203 is installed on the rotating disk 211. The positioning sensor 209 is used to sense the rotation angle positioning of the rotating disk 211 and can be a photoelectric sensor or an electromagnetic sensor. After the display stand 2 rises to the top of the display table 4, the power supply is connected to the conductive slip ring 210 through the power supply contact 15, thereby supplying power to the lighting lamp 201. When the display stand 2 descends, the power supply contact 15 is disconnected from the conductive slip ring 210, and the lighting lamp 201 is extinguished.

[0051] like Figure 2 、 4 As shown in Figure 10, as a preferred embodiment of the above embodiment, the inner cavity 5 of the display stand 4 is divided into an upper storage cavity and a lower transmission cavity by a partition 6; the display rack 2 is located in the storage cavity; a screw rod 7 is provided in the transmission cavity, a connecting rod 10 is provided at the upper end of the screw rod 7, and the lower end is connected to the motor 12; the upper end of the connecting rod 10 passes through the partition 6 and is connected to the one-way rotating wheel 11; the one-way rotating wheel 11 is provided in the hollow shaft 204; the bottom surface of the one-way rotating wheel 11 is provided with an annular tooth surface 113; the bottom of the hollow shaft 204 is provided with a face gear ring 13; the annular tooth surface 113 cooperates with the face gear ring 13; a lifting plate 9 is provided on the screw rod 7; a guide shaft 8 is provided at the bottom of the display rack 2, and the guide shaft 8 passes through the partition 6 and is connected to the lifting plate 9.

[0052] like Figure 14-15 As shown, as a preferred embodiment of the above embodiment, the one-way rotating wheel 11 includes a first ratchet 111 connected to the connecting rod 10, and a rotatable outer wheel 112 is coaxially arranged outside the first ratchet 111, and an annular tooth surface 113 is arranged under the outer wheel 112; the pawl of the first ratchet 111 is arranged on the inner side of the outer wheel 112.

[0053] Specifically, the connecting rod 10 is coaxially connected to the screw rod 7, the connecting rod 10 is located in the storage cavity, and the screw rod 7 is located in the transmission cavity; a one-way rotating wheel 11 is installed on the top of the connecting rod 10 and extends into the hollow shaft 204; when the display rack 2 rises to the top surface of the display table 4, the one-way rotating wheel 11 is engaged with the face gear ring 13 through the annular tooth surface 113, thereby driving the rotating disk 211 to rotate.

[0054] like Figure 11 、 16As shown, as a preferred embodiment of the above embodiment, the lifting plate 9 includes a nut 901 connected to the screw rod 7, the nut 901 is in a flange shape, a rotatable second ratchet 904 is coaxially sleeved on the small shaft of the nut 901, and the position of the second ratchet 904 on the small shaft is limited by a nut 905; a rotatable one-way disc 902 is provided outside the second ratchet 904; the lower end of the guide shaft 8 is connected to the one-way disc 902; the pawl of the second ratchet 904 is provided on the inner side of the one-way disc 902; the nut 901 A slot 906 is provided on the top for cooperating with the rocker 903; a switch hole 907 is provided on the one-way disk 902, and a rocker 903 that can be flipped up and down is installed in the switch hole 907 through a pin shaft, and a torsion spring is provided between the rocker 903 and the pin shaft, and the torsion spring makes the rocker 903 snap into the slot 906 when it is in the reset state; a push rod 16 is provided on the bottom surface of the partition 6 for driving the rocker 903 to flip; after the lifting plate 9 rises to the top, the push rod 16 drives the rocker 903 to tilt up, so that the rocker 903 is separated from the slot 906.

[0055] Specifically, the screw rod 7 is driven to rotate by the motor 12, and the screw rod 7 drives the nut disk 901 to move up and down, and the nut disk 901 drives the one-way disk 902 above it to move up and down synchronously. The one-way disk 902 is connected to the guide shaft 8, so the guide shaft 8 drives the entire display stand 2 to move up and down.

[0056] When the display stand 2 rises to the top, the seesaw 903 on the one-way disk 902 touches the top rod 16 on the bottom surface of the partition 6, and the top rod 16 squeezes the seesaw 903 to flip, so that the seesaw 903 disengages from the slot 906. At this time, the limit of the nut disc 901 and the one-way disk 902 in the rotation direction is eliminated, that is, the nut disc 901 can rotate synchronously with the screw rod 7 without continuing to rise, and the one-way rotating wheel 11 at this time is just engaged with the face gear ring 13 at the bottom of the hollow shaft 204, so that the screw rod 7 drives the connecting rod 10 to rotate, the connecting rod 10 drives the one-way rotating wheel 11 to rotate, the one-way rotating wheel 11 drives the hollow shaft 204 to rotate, and the hollow shaft 204 drives the entire display stand 2 to rotate, thereby realizing the effect of displaying the display box 1 from different sides.

[0057] When the screw rod 7 rotates in the reverse direction, the display stand 2 does not rotate because the one-way rotating wheel 11 does not apply force in the reverse direction. There is a second ratchet 904 between the nut disc 901 and the one-way disc 902, so the nut disc 901 is restricted by the second ratchet 904 and does not rotate. Therefore, the nut disc 901 will fall with the reverse rotation of the screw rod 7, thereby disengaging the rocker 903 from the top rod 16. The rocker 903 is reset under the action of the torsion spring and then snaps into the slot 906; the nut disc 901 and the one-way disc 902 are interlocked in the rotation direction.

[0058] like Figure 12As shown, as a preferred embodiment of the above embodiment, at least two switch holes 907 are arranged in a ring on the one-way disk 902. A pin is installed horizontally in each switch hole 907, and the rocker 903 can be tilted up and down when installed on the pin. A torsion spring is installed between the rocker 903 and the pin to automatically reset the rocker 903 and snap it into the slot 906.

[0059] like Figure 10 As shown, as a preferred embodiment of the above embodiment, a hole is opened on the side of the storage cavity, and then an ultraviolet lamp 14 is provided. When the ultraviolet lamp 14 is turned on, the soil in the display box 1 can be disinfected. Moreover, the ultraviolet lamp 14 is located in the storage cavity, and the light is not irradiated to the outside, thereby ensuring safety.

[0060] The specific working principle of this device: Place the display box 1 into the mounting slot 202, aligning the lower positioning hole 103 with the positioning protrusion 206 on the display stand 2. Then, secure the display box 1 by passing a bolt through the fixing hole 205 and into the upper positioning hole 101. The heat-conducting rod 102 senses the soil temperature inside the display box 1 and transmits this information to the positioning protrusion 206. Positioning protrusion 206 can be a raised temperature sensor, sensing the temperature inside the display box 1 and detecting any abnormalities as soon as possible.

[0061] The motor 12 drives the screw rod 7 to rotate, and the screw rod 7 drives the nut 901 to rise, driving the guide shaft 8 upward. The guide shaft 8 is connected to the display stand 2, so the display stand 2 rises accordingly; When the display rack 2 rises to the top surface of the display platform 4, the seesaw 903 on the one-way disk 902 touches the top rod 16 on the bottom surface of the partition 6. The top rod 16 squeezes the seesaw 903 and flips it, so that the seesaw 903 disengages from the slot 906. At this time, the limit of the nut 901 and the one-way disk 902 in the rotation direction is eliminated, that is, the nut 901 can rotate synchronously with the screw rod 7 without continuing to rise; at this time, the one-way rotating wheel 11 is just engaged with the face gear ring 13 at the bottom of the hollow shaft 204; After the display stand 2 rises to the top surface of the display platform 4, if the display stand 2 needs to be rotated to display different display boxes 1, the motor 12 continues to drive the screw rod 7 to rotate in the forward direction, the screw rod 7 drives the connecting rod 10 to rotate, and the connecting rod 10 drives the one-way rotating wheel 11 to rotate. The one-way rotating wheel 11 just meshes with the face gear ring 13 at the bottom of the hollow shaft 204, so the one-way rotating wheel 11 drives the hollow shaft 204 to rotate, and the hollow shaft 204 drives the entire display stand 2 to rotate, thereby achieving the effect of displaying the display boxes 1 from different sides; at this time, the rotation angle of the display stand 2 can be sensed by the positioning sensor 209, thereby controlling the start and stop of the motor 12.

[0062] After the display is completed, the motor 12 drives the screw rod 7 to rotate in the opposite direction. When the screw rod 7 rotates in the opposite direction, since the one-way rotating wheel 11 is controlled by the first ratchet 111, no force is applied during the reverse rotation, so the display stand 2 does not rotate. There is a second ratchet 904 between the nut disc 901 and the one-way disc 902, so the nut disc 901 is restricted by the second ratchet 904 and does not rotate. Therefore, the nut disc 901 will drop as the screw rod 7 rotates in the opposite direction, thereby causing the rocker plate 903 to disengage from the top rod 16. The rocker plate 903 is reset under the action of the torsion spring and then snaps into the card slot 906; the nut disc 901 and the one-way disc 902 are interlocked in the rotation direction; until the display stand 2 drops to the bottom of the storage cavity, at which time the top plate 208 of the display stand 2 closes the top surface of the storage cavity.

[0063] A process for preserving and displaying a soil profile in its original state, using a device for preserving and displaying a soil profile in its original state, comprises the following steps: A collection pit was excavated at a location with a clear soil layer and compacted surface soil. A geometric sample of soil was trimmed from the pit wall. During the trimming process, a thin sheet was used to insert several slots into the sample soil. The sample soil was then peeled off from the pit using a sample box to obtain the original rice soil sample. According to the required thickness of the sample soil, use a stainless steel knife to remove excess soil blocks, control the thickness of the trimmed sample soil, and keep the surface of the sample soil flat to avoid pits, and store it under constant temperature and humidity; Allow to dry naturally, keeping the soil moisture content at 15%-25%; Place the soil samples that have been dried to sterilize them in an irradiation workshop, maintaining a minimum irradiation dose of 10 kGy. Glue and solidify; use AB glue to seal the disinfected soil sample, and place the sealed soil sample in the display box 1.
