Description

Technical Field

[0001] The invention relates to the technical field of undisturbed soil sample preservation, in particular to an anti-disturbance preservation device for undisturbed soil samples in highway engineering surveys. Background Art

[0002] Original soil, also known as undisturbed soil sample or original soil sample, refers to soil samples collected from field soil without any modification. It is a soil sample that maintains natural moisture content and natural structure. Original soil samples can better reflect the true situation of the soil than those collected from different depths. Therefore, the results of measuring its soil indicators are usually more accurate.

[0003] To determine soil dry density, moisture content, porosity, and (indirectly) soil particle composition and hygroscopic water content—values crucial for assessing soil engineering properties, moisture status, and fertility—undisturbed soil samples must be dried. However, the evaporation of moisture from dried undisturbed soil samples weakens the bond between soil particles, making this looseness difficult to retrieve and test. To address this issue, we propose a device for preserving undisturbed soil samples from highway engineering surveys. Summary of the Invention

[0004] The purpose of the present invention is to provide a device for preventing disturbance of original soil samples for highway engineering survey, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a device for preserving undisturbed soil samples for highway engineering surveys, comprising a preserving mechanism, the preserving mechanism comprising a box body, a box cover mounted on the top of the box body, a sealing ring mounted on the bottom of the box cover, a spring mounted on the bottom of the box cover, a sealing plate fixedly connected to the bottom of the spring, a handle fixedly connected to the top of the box cover, a lock mounted on the outside of the box body, and a retrieval mechanism disposed inside the box body;

[0006] The taking mechanism includes a driving unit, which is installed inside the box and is used to push the original soil sample out of the box;

[0007] The driving unit includes a placement block, an electric push rod is fixedly installed on the inner bottom wall of the box, a guide block is fixedly connected to the outer side of the placement block, a placement slot is opened on the top of the placement block, a shock-absorbing pad is fixedly installed on the inner bottom wall of the box, a guide slot is opened on the inner side wall of the box, and a moving slot is opened on the bottom of the placement block;

[0008] The taking mechanism further includes a lifting unit, which is installed inside the box body and cooperates with the driving unit to further push out the original soil sample;

[0009] The lifting unit includes an installation cavity, a servo motor is fixedly installed on the inner bottom wall of the installation cavity, the output shaft of the servo motor is fixedly connected to the rotating shaft, the top of the rotating shaft is fixedly connected to the turntable, the top of the turntable is fixedly connected to the protrusion, the outer side of the protrusion is sleeved with a movable frame, the outer side of the movable frame is fixedly connected to the first connecting rod, a connecting plate is fixedly installed on one side of the first connecting rod, a second connecting rod is fixedly installed on one side of the connecting plate, a first wedge block is fixedly installed on one side of the second connecting rod, a slider is slidably installed in the placement block, a push plate is fixedly connected on one side of the slider, the bottom of the push plate is fixedly connected to the third connecting rod, the bottom of the third connecting rod is fixedly connected to the second wedge block, and a sliding groove is provided on the placement block.

[0010] Preferably, there are two electric push rods and they are symmetrically distributed on the inner bottom wall of the box. The shock-absorbing pad is located between the two electric push rods. The top surface of the shock-absorbing pad is in contact with the bottom surface of the placement block. Both sides of the placement block are in contact with the shock-absorbing pad. The shock-absorbing pad is made of rubber.

[0011] By setting up two symmetrical electric push rods, the stability and balance of the placement block during the lifting process are ensured, and the tilting of the placement block due to unilateral force is effectively avoided. The shock-absorbing pad is made of elastic and wear-resistant rubber material, which can effectively absorb and disperse the impact force generated by the electric push rod or other external factors, thereby protecting the original soil sample on the placement block from damage.

[0012] Preferably, there are two guide blocks and they are symmetrically installed on both sides of the placement block. The surface of the guide block is smoothly designed and is located in the middle of the side of the placement block. There are two guide grooves and they are symmetrically distributed on the inner wall of the box. The top of the guide groove extends to the top of the box. There are four placement grooves and they are symmetrically distributed in pairs.

[0013] By installing a guide block with a smooth surface, the friction resistance of the placement block during movement can be reduced. At the same time, the two guide grooves located on the inner wall of the box provide a clear path for the lifting and lowering of the placement block. In addition, the four placement slots opened on the placement block can be used to store original soil samples of different depths. The results of measuring its soil indicators are usually more accurate and can better reflect the actual situation of the soil.

[0014] Preferably, there are two movable grooves and they are symmetrically distributed at the bottom of the placement block. The output end of the electric push rod extends into the movable groove and fits into the bottom of the placement block. The size of the movable groove is adapted to the moving trajectory of the output end of the electric push rod.

[0015] By symmetrically designing two movable grooves at the bottom of the placement block, it can be adapted to the output end of the electric push rod. When the electric push rod is working, its output end will extend into the movable groove and fit with the bottom of the placement block, thereby pushing the placement block to move up and down. The size of the movable groove has been precisely calculated to ensure that it fully matches the moving trajectory of the output end of the electric push rod, thereby achieving smooth and smooth lifting and lowering operations.

[0016] Preferably, the installation cavity is opened inside the placement block, the number of the protrusions is two and they are symmetrically distributed on the top of the turntable, and a strip through hole is opened inside the movable frame, and the size of the strip through hole is adapted to the moving trajectory of the protrusion.

[0017] By opening an installation cavity in the placement block, it can be used to install other necessary machinery or structures. Two protrusions are symmetrically distributed on the top of the turntable. These protrusions are adapted to the bar-shaped through holes in the movable frame, allowing the turntable to rotate within a certain range. The turntable drives the protrusions to rotate, and the protrusions push the movable frame to move.

[0018] Preferably, the number of the first connecting rods is two and they are respectively installed on the opposite sides of the two movable frames, the number of the connecting plates is two and they are respectively installed on the opposite sides of the two first connecting rods, the opposite sides of the two connecting plates are fixedly connected with two second connecting rods, and the two second connecting rods on a single connecting plate are symmetrically distributed.

[0019] By installing first connecting rods on opposite sides of the two movable frames, these first connecting rods are further connected to two connecting plates, and two second connecting rods are fixed on each connecting plate, and the second connecting rods are symmetrically distributed on a single connecting plate. This design not only enhances the stability of the first wedge block during movement, but also provides a basis for subsequent mechanical linkage.

[0020] Preferably, the push plate is located inside the placement groove, two sliders are installed in a single placement groove, the push plate is fixedly installed between the two sliders, the slide groove is connected to the placement groove, and the size of the slide groove is adapted to the moving trajectory of the slider.

[0021] By fixing a push plate between the two sliders, the dried original soil sample to be tested can be placed on the push plate. The slide groove is connected to the placement groove, which can ensure that the slider can move smoothly inside the slide groove and the push plate can move smoothly inside the placement groove, ensuring the stability of the original soil sample during the movement.

[0022] Preferably, the third connecting rod extends from the placement groove to the installation cavity, the side of the first wedge block close to the third connecting rod is designed with a slope, and the side of the second wedge block close to the second connecting rod is designed with a slope, and the inclination angles of the slopes on the opposite sides of the first wedge block and the second wedge block are the same.

[0023] By extending the third connecting rod from the placement groove to the installation cavity, a connection and transmission function is achieved. The opposite sides of the first wedge block and the second wedge block both adopt a slope design, and their inclination angles are the same. This design allows the two first wedge blocks to drive the two second wedge blocks to descend or ascend when they move relative to or away from each other.

[0024] Preferably, a limiting mechanism is provided on the taking mechanism, and the limiting mechanism includes a limiting block, a movable rod is fixedly installed on one side of the limiting block, a clamping ring is fixedly connected to the outer side of the movable rod, a clamping hole is opened on the clamping ring, and a clamping plate is fixedly installed inside the placement block.

[0025] The limit block with a smooth surface can reduce the friction of the movable rod during the up and down movement. When the clamping plate deflects together with the placement block until it fits into the clamping hole on the clamping ring, the position of the placement block can be locked to prevent the placement block from continuing to deflect and causing the original soil sample in the placement groove to fall.

[0026] Preferably, there are two limit blocks and their surfaces are designed to be smooth. The movable rod is fixedly installed between the two limit blocks. The interior of the placement block is provided with a movable cavity that is adapted to the rotation trajectory of the card plate. The inner side wall of the box body is provided with a movable groove that is adapted to the moving trajectory of the movable rod. The inner side wall of the box body is provided with a limit groove that is adapted to the moving trajectory of the limit block.

[0027] By opening an active cavity in the placement block that is compatible with the rotation trajectory of the card plate, sufficient space is provided for the rotation of the card plate. By opening an active groove that is compatible with the moving trajectory of the movable rod and a limit groove that is compatible with the moving trajectory of the limit block on the inner side wall of the box, not only can the smooth movement of the placement block in the box be ensured, but also the deflection of the placement block before it is moved out of the box can be prevented, thereby improving the reliability of the entire device.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The present invention places the original soil sample into the placement groove on the placement block. When it needs to be taken out, the electric push rod is started to push the placement block up until it moves out of the box. The output end of the electric push rod continues to rise, causing the placement block to deflect. Then the electric push rod is turned off, and the servo motor is started to drive the turntable to rotate forward. The two protrusions drive the movable frame to move back to each other. Under the push of the first wedge block, the second wedge block drives the push plate to move up, pushing out the original soil sample in the placement groove, thereby achieving the effect of convenient taking.

[0030] 2. In the present invention, when the placement block deflects, the clamping plate deflects together in the movable cavity until the clamping plate deflects to fit into the clamping hole on the clamping ring. At this time, the clamping plate and the placement block can no longer deflect, and the electric push rod is closed to prevent the placement block from excessively deflecting and causing the original soil sample in the placement slot to fall.

DETAILED DESCRIPTION

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] Example 1

[0044] See also Figure 1-10 The present invention provides a technical solution: a device for preserving undisturbed soil samples for highway engineering surveys, comprising a preserving mechanism 1, the preserving mechanism 1 comprising a box body 11, a box cover 12 being mounted on the top of the box body 11, a sealing ring 13 being mounted on the bottom of the box cover 12, a spring 14 being mounted on the bottom of the box cover 12, a sealing plate 15 being fixedly connected to the bottom of the spring 14, a handle 16 being fixedly connected to the top of the box cover 12, a lock buckle 17 being mounted on the outside of the box body 11, and a taking mechanism 2 being disposed inside the box body 11;

[0045] The taking mechanism 2 includes a driving unit 21, which is installed inside the box 11 and is used to push the original soil sample out of the box 11;

[0046] As a further limitation of the picking mechanism 2 of the present invention, the driving unit 21 includes a placement block 2101, an electric push rod 2102 is fixedly installed on the inner bottom wall of the box body 11, a guide block 2103 is fixedly connected to the outer side of the placement block 2101, a placement groove 2104 is opened on the top of the placement block 2101, a shock-absorbing pad 2105 is fixedly installed on the inner bottom wall of the box body 11, a guide groove 2106 is opened on the inner side wall of the box body 11, and a moving groove 2107 is opened on the bottom of the placement block 2101. By placing the original soil sample into the placement groove 2104 on the placement block 2101, When it is necessary to take it out, the electric push rod 2102 is started to push the placement block 2101 upward until it moves out of the box 11. The output end of the electric push rod 2102 continues to rise, causing the placement block 2101 to deflect. Then the electric push rod 2102 is closed, and the servo motor 2202 is started to drive the turntable 2204 to rotate forward. The two protrusions 2205 drive the movable frame 2206 to move backward. Under the push of the first wedge block 2210, the second wedge block 2214 drives the push plate 2212 to move upward, pushing out the original soil sample in the placement groove 2104, so as to achieve the effect of convenient taking;

[0047] There are two electric push rods 2102 and they are symmetrically distributed on the inner bottom wall of the box body 11. The shockproof pad 2105 is located between the two electric push rods 2102. The top surface of the shockproof pad 2105 is in contact with the bottom surface of the placement block 2101, and both sides of the placement block 2101 are in contact with the shockproof pad 2105. The shockproof pad 2105 is made of rubber. By providing two symmetrical electric push rods 2102, the stability and balance of the placement block 2101 during the lifting process are ensured, and the tilting of the placement block 2101 due to unilateral force is effectively avoided. The shockproof pad 2105 is made of elastic and wear-resistant rubber material, which can effectively absorb and disperse the impact force generated by the electric push rods 2102 or other external factors, thereby protecting the original soil sample on the placement block 2101 from damage;

[0048] There are two guide blocks 2103, which are symmetrically installed on both sides of the placement block 2101. The surface of the guide blocks 2103 is smooth and located in the middle of the side of the placement block 2101. There are two guide grooves 2106, which are symmetrically distributed on the inner wall of the box body 11. The top of the guide grooves 2106 extends to the top of the box body 11. There are four placement grooves 2104, which are symmetrically distributed in pairs. By installing the guide blocks 2103 with smooth surfaces, the friction resistance of the placement block 2101 during movement can be reduced. At the same time, the two guide grooves 2106 located on the inner wall of the box body 11 provide a clear path for the lifting and lowering of the placement block 2101. In addition, the four placement grooves 2104 opened on the placement block 2101 can be used to store undisturbed soil samples of different depths. The results of measuring its soil indicators are usually more accurate and can better reflect the actual situation of the soil.

[0049] There are two movable grooves 2107, which are symmetrically distributed at the bottom of the placement block 2101. The output end of the electric push rod 2102 extends into the movable groove 2107 and fits with the bottom of the placement block 2101. The size of the movable groove 2107 is adapted to the moving trajectory of the output end of the electric push rod 2102. By symmetrically designing two movable grooves 2107 at the bottom of the placement block 2101, it can be adapted to the output end of the electric push rod 2102. When the electric push rod 2102 is working, its output end will extend into the movable groove 2107 and fit with the bottom of the placement block 2101, thereby pushing the placement block 2101 to perform lifting and lowering movements. The size of the movable groove 2107 has been precisely calculated to ensure that it is fully matched with the moving trajectory of the output end of the electric push rod 2102, thereby achieving smooth and smooth lifting and lowering operations.

[0050] The specific implementation of this embodiment is as follows: when the original soil sample needs to be taken out from the placement groove 2104, the electric push rod 2102 is first started to extend its output end. Under the action of the guide block 2103 and the guide groove 2106, the placement block 2101 moves upward in the box body 11. When the placement block 2101 continues to move upward until the guide block 2103 moves out of the guide groove 2106, the limiting effect of the guide block 2103 on the angle of the placement block 2101 is released, and the electric push rod 2102 continues to extend its output end. The output end of the electric push rod 2102 moves in the moving groove 2107, causing the placement block 2101 to deflect, thereby initially achieving the purpose of facilitating the removal of the original soil sample in the placement groove 2104.

[0052] See also Figure 1-10 The present invention provides a technical solution: an anti-disturbance preservation device for original soil samples in highway engineering surveys. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0053] As a further limitation of the picking mechanism 2 of the present invention, the picking mechanism 2 further includes a lifting unit 22, which is installed inside the box 11. The lifting unit 22 cooperates with the driving unit 21 to further push out the original soil sample;

[0054] The lifting unit 22 includes a mounting cavity 2201, a servo motor 2202 is fixedly mounted on the inner bottom wall of the mounting cavity 2201, an output shaft of the servo motor 2202 is fixedly connected to a rotating shaft 2203, a turntable 2204 is fixedly connected to the top of the rotating shaft 2203, a protrusion 2205 is fixedly connected to the top of the turntable 2204, a movable frame 2206 is sleeved on the outer side of the protrusion 2205, a first connecting rod 2207 is fixedly connected to the outer side of the movable frame 2206, a connecting plate 2208 is fixedly mounted on one side of the first connecting rod 2207, a second connecting rod 2209 is fixedly mounted on one side of the connecting plate 2208, a first wedge block 2210 is fixedly mounted on one side of the second connecting rod 2209, and a sliding block 2210 is placed in the placement block 2101.

When the placement block 2101 is deflected, the electric push rod 2102 is turned off, and the servo motor 2202 is started to drive the turntable 2204 to rotate forward, so that the two protrusions 2205 drive the two movable frames 2206 to move back to each other. Under the push of the first wedge block 2210, the second wedge block 2214 drives the push plate 2212 to move upward, pushing out the original soil sample in the placement groove 2104, further achieving the purpose of facilitating the removal of the original soil sample.

[0055] The mounting cavity 2201 is provided inside the placement block 2101. There are two protrusions 2205 symmetrically distributed on the top of the turntable 2204. A strip-shaped through-hole is provided inside the movable frame 2206. The size of the strip-shaped through-hole matches the movement trajectory of the protrusion 2205. By providing the mounting cavity 2201 in the placement block 2101, it can be used to install other necessary machinery or structures. Two protrusions 2205 are symmetrically distributed on the top of the turntable 2204. These protrusions 2205 match the strip-shaped through-holes in the movable frame 2206, allowing the turntable 2204 to rotate within a certain range. The turntable 2204 drives the protrusions 2205 to rotate, and the protrusions 2205 push the movable frame 2206 to move.

[0056] There are two first connecting rods 2207, which are respectively installed on the opposite sides of the two movable frames 2206. There are two connecting plates 2208, which are respectively installed on the opposite sides of the two first connecting rods 2207. Two second connecting rods 2209 are fixedly connected to the opposite sides of the two connecting plates 2208. The two second connecting rods 2209 on a single connecting plate 2208 are symmetrically distributed. By respectively installing the first connecting rods 2207 on the opposite sides of the two movable frames 2206, these first connecting rods 2207 are further connected to the two connecting plates 2208, and two second connecting rods 2209 are fixed on each connecting plate 2208, and the second connecting rods 2209 are symmetrically distributed on a single connecting plate 2208. This design not only enhances the stability of the first wedge block 2210 during movement, but also provides a basis for subsequent mechanical linkage.

[0057] The push plate 2212 is located inside the placement groove 2104. Two sliders 2211 are installed in a single placement groove 2104. The push plate 2212 is fixedly installed between the two sliders 2211. The slide 2215 is connected to the placement groove 2104. The size of the slide 2215 is adapted to the movement trajectory of the slider 2211. By fixing a push plate 2212 between the two sliders 2211, the dried original soil sample to be tested can be placed on the push plate 2212. The slide 2215 is connected to the placement groove 2104, which can ensure that the slider 2211 can move smoothly inside the slide 2215 and the push plate 2212 moves smoothly inside the placement groove 2104, thereby ensuring the stability of the original soil sample during the movement.

[0058] The third connecting rod 2213 extends from the placement groove 2104 to the installation cavity 2201. The side of the first wedge block 2210 close to the third connecting rod 2213 is designed with a slope, and the side of the second wedge block 2214 close to the second connecting rod 2209 is designed with a slope. The inclination angles of the slopes on the opposite sides of the first wedge block 2210 and the second wedge block 2214 are the same. By extending the third connecting rod 2213 from the placement groove 2104 to the installation cavity 2201, a connection and transmission function is achieved. The opposite sides of the first wedge block 2210 and the second wedge block 2214 both adopt a slope design, and their inclination angles are the same. This design allows the two first wedge blocks 2210 to drive the two second wedge blocks 2214 to descend or ascend when they move relative to or away from each other.

[0059] The specific implementation of this embodiment is as follows: when the placement block 2101 is deflected, the servo motor 2202 is started to drive the rotating shaft 2203 and the turntable 2204 to rotate forward, and the protrusion 2205 on the turntable 2204 rotates forward together, and the two movable frames 2206 are pushed to move back to each other through the two protrusions 2205. Under the action of the first connecting rod 2207, the connecting plate 2208, the second connecting rod 2209 and the first wedge block 2210, the second wedge block 2214 is pushed upward, and under the transmission of the third connecting rod 2213, the push plate 2212 is stably moved upward under the limit of the slider 2211 and the slide groove 2215, and the original soil sample in the placement groove 2104 is pushed out, so as to facilitate the removal of the original soil sample that has become loose due to drying.

[0060] Example 3

[0061] See also Figure 1-10 The present invention provides a technical solution: an anti-disturbance preservation device for original soil samples in highway engineering surveys. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0062] As a further limitation of the picking mechanism 2 of the present invention, the limiting mechanism 3 includes a limiting block 301, a movable rod 302 is fixedly installed on one side of the limiting block 301, a clamping ring 303 is fixedly connected to the outer side of the movable rod 302, a clamping hole 304 is opened on the clamping ring 303, and a clamping plate 305 is fixedly installed inside the placement block 2101. The limiting block 301 with a smooth surface can reduce the friction of the movable rod 302 during the up and down movement. When the clamping plate 305 deflects together with the placement block 2101 until it fits into the clamping hole 304 on the clamping ring 303, the position of the placement block 2101 can be locked, preventing the placement block 2101 from continuing to deflect and causing the original soil sample in the placement groove 2104 to fall off;

[0063] There are two limit blocks 301 and their surfaces are smooth. The movable rod 302 is fixedly installed between the two limit blocks 301. The interior of the placement block 2101 is provided with a movable cavity 306 adapted to the rotation trajectory of the card plate 305. The inner side wall of the box body 11 is provided with a movable groove 307 adapted to the moving trajectory of the movable rod 302. The inner side wall of the box body 11 is provided with a limit groove 308 adapted to the moving trajectory of the limit block 301. The movable cavity 306 adapted to the rotation trajectory of the card plate 305 provides sufficient space for the rotation of the card plate 305. By providing a movable groove 307 adapted to the moving trajectory of the movable rod 302 and a limit groove 308 adapted to the moving trajectory of the limit block 301 on the inner side wall of the box body 11, it can not only ensure that the placement block 2101 moves smoothly in the box body 11, but also prevent the placement block 2101 from deflecting before being moved out of the box body 11, thereby improving the reliability of the entire device.

[0064] The specific implementation of this embodiment is: when the placement block 2101 is deflected, the clamping plate 305 is grasped together in the movable cavity 306 until the clamping plate 305 is deflected to fit with the clamping hole 304 on the clamping ring 303. At this time, the clamping plate 305 and the placement block 2101 can no longer deflect. At this time, closing the electric push rod 2102 can prevent the placement block 2101 from excessively deflecting and causing the original soil sample in the placement groove 2104 to fall out.
