Description

A soil remediation earthwork backfilling and compaction device Technical Field

[0001] This application relates to the field of soil remediation engineering technology, and in particular to a soil remediation backfilling and compaction device. Background Technology

[0002] In the fields of building construction, road construction, and foundation treatment, compaction equipment is a key tool for compacting loose soil, increasing foundation density, and repairing soil. Among various compaction equipment, the frog-type compactor is widely used in trench backfilling, small-scale road repair, and other scenarios due to its simple structure and flexible operation. Its compaction efficiency and operational stability directly affect construction quality and project progress.

[0003] In existing technologies, traditional frog-type compactors typically use an electric motor to drive an eccentric block, generating centrifugal force. This centrifugal force causes the compaction plate to periodically jump and impact the ground, thus achieving the purpose of compacting soil or small road surfaces.

[0004] Regarding the aforementioned technologies, for heavy metal contaminated soil, it is necessary to add a solidifying agent or adjust the compaction strength before compaction. Existing equipment cannot simultaneously complete the spraying of the agent or the adjustment of the compaction strength, resulting in process separation and low efficiency. Summary of the Invention

[0005] To improve the compaction efficiency of soil contaminated with heavy metals, this application provides a soil remediation backfill compaction device.

[0006] The soil remediation backfilling and compaction device provided in this application adopts the following technical solution:

[0007] A soil remediation backfilling and compaction device includes a support base, a transmission component, a centrifugal component, and a spraying component; a support shell is fixedly installed on the top of the support base, the transmission component is fixedly installed on the top of the support base, and the support shell covers the transmission component.

[0008] The transmission assembly includes transmission wheels, a drive motor, a transmission shaft, and a compaction swing component. There are four transmission wheels: a first transmission wheel, a second transmission wheel, a third transmission wheel, and a fourth transmission wheel. The first transmission wheel is coaxially fixedly mounted on the output end of the drive motor. The second and third transmission wheels are coaxially connected to the transmission shaft. The fourth transmission wheel is rotatably connected to the compaction swing component. The first transmission wheel is connected to the second transmission wheel via a first transmission belt, and the third transmission wheel is connected to the fourth transmission wheel via a second transmission belt. The transmission shaft is fixedly mounted on the top of the support base. One end of the compaction swing component is coaxially rotatably connected to the transmission shaft. A compaction plate is fixedly mounted on one end of the compaction swing component. The compaction plate is located at the bottom of the fourth transmission wheel, and the bottom of the compaction plate is flat.

[0009] The centrifugal components are provided in a plurality of manner, and the plurality of centrifugal components are respectively disposed at both ends of the fourth transmission wheel. The centrifugal components are fixedly connected to the fourth transmission wheel. A centrifugal weight is provided inside the centrifugal component. The centrifugal weight is eccentrically arranged relative to the axis of the fourth transmission wheel. The position of the centrifugal weight inside the centrifugal component will rotate together with the fourth transmission wheel.

[0010] The spraying assembly includes a water tank, a spray pipe, and a mechanical swing arm. The water tank has a water inlet, the spray pipe is connected to the inside of the water tank, the spray pipe is fixedly installed on the mechanical swing arm, and the top of the spray pipe is equipped with a switch valve. The spray pipe can draw out the liquid inside the water tank, and the mechanical swing arm is rotatably connected to the top of the water tank.

[0011] By adopting the above technical solution, when compacting soil contaminated with heavy metals, the valve of the spraying component can be opened to spray the solidifying agent inside the water tank onto the soil, which is then compacted with a tamping plate. Alternatively, when the environment is confined and spraying is inconvenient, the position of the centrifugal weight inside the centrifugal component can be adjusted to increase the centrifugal force, thereby increasing the compaction pressure of the tamping swing component and thus improving the compaction efficiency of the heavy metal-contaminated soil.

[0012] Optionally, the centrifuge component has a first sliding chamber and a second sliding chamber inside, the first sliding chamber is connected to the second sliding chamber, the extension direction of the first sliding chamber and the extension direction of the second sliding chamber are arranged in a "T" shape, the centrifuge weight can slide and fit into the first sliding chamber, the centrifuge weight can slide along the radial direction of the fourth transmission wheel, the top of the first sliding chamber is provided with a first spring, and the centrifuge component has a weight adjustment assembly inside, the weight adjustment assembly can control the sliding or fixed state of the centrifuge weight in the first sliding chamber.

[0013] By adopting the above technical solution, the fixed or sliding state of the centrifugal weight in the first sliding chamber can be controlled by the weight adjustment component, thereby changing the centrifugal force generated when the centrifugal component rotates, so that the compaction pressure of the compaction swing component can adapt to the soil contaminated with heavy metals.

[0014] Optionally, the centrifuge component is provided with two weight adjustment assemblies. The two weight adjustment assemblies are arranged opposite to each other at both ends of the second sliding chamber. Each weight adjustment assembly includes an adjustment rod, an adjustment top rod, an adjustment sleeve, and an adjustment block. The adjustment rod is sleeved on the adjustment top rod and passes through the adjustment sleeve. The adjustment rod is slidably engaged with the adjustment sleeve, and the adjustment top rod is rotatably connected to the adjustment sleeve.

[0015] The adjusting rod has several triangular grooves at one end, and several raised sliders at one end of the triangular grooves. The adjusting rod has several inclined sliders at one end, which can engage with the triangular grooves. The adjusting sleeve has several first slides and several second slides, which are alternately arranged inside the adjusting sleeve with varying depths. Several limiting blocks are provided between the first and second slides, which can interfere with the engagement state of the inclined sliders and the triangular grooves. Several raised sliders slide and engage with the first or second slides. The adjusting block is fixedly connected to the adjusting rod, and the adjusting rod is rotatably connected to the adjusting rod. A first positioning block is fixedly installed on the adjusting rod, and a second positioning block is fixedly installed in the second sliding chamber. The adjusting rod slides through the second positioning block and engages with the second sliding chamber. A second spring is provided between the first and second positioning blocks.

[0016] By adopting the above technical solution, when the centrifugal component is rotated so that the centrifugal weight can press against the first spring, the adjusting rods at both ends of the centrifugal component can be pressed. The adjusting rods at both ends can push the positioning blocks located at both ends of the second sliding chamber into the first sliding chamber. At this time, the positioning blocks, the centrifugal weight, and the first spring abut against each other and are fixed in the first sliding chamber, thereby fixing the centrifugal weight and reducing the centrifugal force. When it is necessary to increase the centrifugal force, the adjusting rods can be pressed again, causing the adjusting rods to drive the positioning blocks back into the second sliding chamber. The centrifugal weight can slide in the first sliding chamber. When the centrifugal component rotates, the centrifugal weight sliding in the first sliding chamber can increase the centrifugal force due to inertia.

[0017] Optionally, the mechanical swing arm includes a transmission swing rod, a support rod, and a rotating base. There are two transmission swing rods, which are rotatably connected to both sides of the rotating base. The middle part of the transmission swing rod can rotate. Several connecting rods are provided between the two sets of transmission swing rods. The two ends of the support rod are rotatably connected to the two connecting rods located at both ends of the transmission swing rod. The rotating base is rotatably connected to the top of the water tank.

[0018] By adopting the above technical solution, the mechanical swing arm can be rotatably connected to the water storage tank, and the rotation of the mechanical swing arm can change the spray direction of the spray pipe.

[0019] Optionally, the spray pipe branches into several spray heads, and the spray heads are fixedly connected to the mechanical swing arm.

[0020] By adopting the above technical solution, the spraying range of the curing agent can be increased, thereby increasing the spraying efficiency and improving economic efficiency.

[0021] Optionally, a push-pull handle is installed on the top of the support base, and the push-pull handle is rotatably connected to the support base.

[0022] By adopting the above technical solution, workers can change the compaction direction of the equipment by pushing and pulling the handrail, thereby improving compaction efficiency.

[0023] Optionally, the surface of the push-pull armrest is provided with anti-slip texture.

[0024] By adopting the above technical solution, the anti-slip texture can improve the stability of the ground compaction when workers operate equipment.

[0025] Optionally, the top of the support base is vertically provided with two motor mounting parts, each motor mounting part having a motor mounting slot adapted to a drive motor, and the drive motor and the support base not having direct rigid contact.

[0026] By adopting the above technical solution, the drive motor does not directly and rigidly contact the support base. The hollow area between the two can effectively reduce the impact of the drive motor's own vibration on the compaction effect of the equipment when it is outputting.

[0027] Optionally, the diameter of the fourth transmission wheel is larger than the diameter of the third transmission wheel.

[0028] By adopting the above technical solution, the torque transmitted from the third drive wheel to the fourth drive wheel is increased, thereby meeting the force required for the centrifugal component to rotate fully.

[0029] Optionally, the surface of the fourth transmission wheel is designed with a hollowed-out shape.

[0030] By adopting the above technical solution, the force required between the centrifugal component and the fourth rotating wheel can be reduced, allowing the centrifugal component to rotate at a faster speed.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. When compacting soil contaminated with heavy metals, the spraying assembly's valve can be opened to spray the solidifying agent from the water tank onto the soil, followed by compaction with a tamping plate. Alternatively, when the environment is confined and spraying is inconvenient, the position of the centrifugal weights inside the centrifugal unit can be adjusted to increase the centrifugal force, thereby increasing the compaction pressure of the tamping oscillating component and improving the compaction efficiency of the heavy metal-contaminated soil.

[0033] 2. When the centrifugal component is rotated so that the centrifugal weight presses against the first spring, the adjusting rods at both ends of the centrifugal component can be pressed. These adjusting rods will push the positioning blocks located at both ends of the second sliding chamber into the first sliding chamber. At this time, the positioning blocks, the centrifugal weight, and the first spring are fixed together within the first sliding chamber, thus fixing the centrifugal weight and reducing the centrifugal force. If it is necessary to increase the centrifugal force, the adjusting rods can be pressed again, causing them to move the positioning blocks back into the second sliding chamber. The centrifugal weight can then slide within the first sliding chamber. When the centrifugal component rotates, the centrifugal weight sliding within the first sliding chamber can increase the centrifugal force due to inertia.

[0034] 3. The drive motor does not directly and rigidly contact the support base. The hollow area between the two effectively reduces the impact of the drive motor's own vibration on the compaction effect of the equipment when it is outputting. Attached Figure Description

[0050] The present application will be further described in detail below with reference to Figures 1-14.

[0051] Example 1:

[0052] Embodiment 1 of this application discloses a soil remediation backfilling and compaction device. Referring to Figure 1, the soil remediation backfilling and compaction device includes a support base 1, a transmission component 2, a centrifugal component 26, and a spraying component 3; a support shell 11 is fixedly installed on the top of the support base 1, the transmission component 2 is installed on the top of the support base 1, and the support shell 11 covers the transmission component 2 to reduce external interference to the transmission component 2 during operation;

[0053] Referring to Figure 2, a push-pull handle 12 is installed on the top of the support base 1, and the push-pull handle 12 is rotatably connected to the support base 1. The push-pull handle 12 serves to adjust the direction of the compaction device. The operator can change the compaction direction of the equipment by applying force to the push-pull handle 12 through horizontal offset, adapting to compaction of heavy metal contaminated soil in confined spaces, thereby improving compaction efficiency. In addition, the surface of the push-pull handle 12 is provided with anti-slip texture 101. The anti-slip texture 101 increases the friction between the operator's palm and the push-pull handle 12, making it more stable for the operator to grip the push-pull handle 12 when operating the compaction equipment.

[0054] Referring to Figure 3, the transmission assembly 2 includes a drive motor 21, a transmission wheel 22, a transmission shaft 23, and a tamping swing member 24. Two motor mounting members 13 are vertically fixed to the top of the support base 1. Each motor mounting member 13 has a motor mounting groove 102 on its top, and the drive motor 21 is fixedly mounted on the inner wall of the motor mounting groove 102. A hollow area is created between the drive motor 21 and the support base 1 to facilitate heat dissipation for the drive motor 21.

[0055] Referring to Figure 4, there are four transmission wheels 22: a first transmission wheel 221, a second transmission wheel 222, a third transmission wheel 223, and a fourth transmission wheel 224. The first transmission wheel 221 is coaxially fixedly mounted on the output end of the drive motor 21, and the transmission shaft 23 is fixedly mounted on the top of the support base 1. The second transmission wheel 222 and the third transmission wheel 223 are both coaxially rotatably connected to the transmission shaft 23. One end of the tamping swing member 24 is coaxially rotatably connected to the transmission shaft 23 and surrounds the third transmission wheel 223 inside. The fourth transmission wheel 224 is rotatably connected to the other end of the tamping swing member 24. A tamping plate 25 is fixedly mounted on one end of the tamping swing member 24. The tamping plate 25 is located at the bottom of the fourth transmission wheel 224, and the bottom of the tamping plate 25 is flat. The first transmission wheel 221 is connected to the second transmission wheel 222 via the first transmission belt, and the third transmission wheel 223 is connected to the fourth transmission wheel 224 via the second transmission belt. The driving force of the drive motor 21 is transmitted to the transmission shaft 23 and the fourth rotating wheel via the belt drive, so that the tamping swinging member 24 can swing continuously, thereby tamping the ground through the tamping plate 25.

[0056] Referring to Figure 4, the diameter of the fourth transmission wheel 224 is larger than that of the third transmission wheel 223, which increases the torque transmitted from the third transmission wheel 223 to the fourth transmission wheel 224, thereby satisfying the inertial force required for the oscillating compactor 24 to swing. Furthermore, the surface of the fourth transmission wheel 224 has a hollow design, which reduces the mass of the fourth transmission wheel 224 itself, allowing the centrifugal component 26 to rotate at a faster speed and thus transmitting a greater inertial force to the oscillating compactor 24.

[0057] Referring to Figure 4, two centrifugal components 26 are provided, located at both ends of the fourth transmission wheel 224 and fixedly connected to it. The center of gravity of the centrifugal component 26 is eccentrically positioned relative to the axis of the fourth transmission wheel 224, so that when the centrifugal component 26 rotates with the fourth transmission wheel 224, it lifts or presses down the compaction swing component 24 through centrifugal force. When driven by the drive motor 21, the fourth transmission wheel 224 and the transmission shaft 23 can rotate through the transmission assembly 2. At this time, the fourth transmission wheel 224 drives the centrifugal component 26 to rotate, and the rotation of the centrifugal component 26 generates a periodic inertial impact force, which drives the compaction swing component 24 to continuously compact the ground.

[0058] Referring to Figure 5, the spraying assembly 3 includes a water tank 31, a spray pipe 32, and a mechanical swing arm 33. The water tank 31 has an inlet 301 through which the curing agent can be stored. The spray pipe 32 is connected to the inside of the water tank 31 via an externally powered water pump (not shown in the figure). The spray pipe 32 is fixedly installed on the mechanical swing arm 33, and a switch valve 34 is located at the top of the spray pipe 32. Two spray heads 35 branch off from the spray pipe 32 and are fixedly connected to the mechanical swing arm 33. When the switch valve 34 is opened, the spray pipe 32 draws the curing agent from the water tank 31 through the water pump inside the water tank 31 and atomizes the curing agent through the spray heads 35, spraying it onto the heavy metal soil that needs treatment. The three spray heads 35 also increase the spraying range of the curing agent, thereby increasing the spraying efficiency.

[0059] Referring to Figure 6, the mechanical swing arm 33 includes a transmission swing rod 36, a support rod 37, and a rotating base 38, and is located on top of the water tank 31. Two transmission swing rods 36 are provided, each rotatably connected to one side of the rotating base 38. The middle of each transmission swing rod 36 is rotatable, allowing adjustment of the angle between its two ends. Three connecting rods are fixedly connected between the two sets of transmission swing rods 36 to maintain the overall stability of the mechanical swing arm 33. The support rod 37 is a buffer-damping telescopic rod, with both ends rotatably connected to the two connecting rods located at the ends of the transmission swing rod 36, so as to maintain the angle between the two ends of the transmission swing rod 36 after it rotates and bends in the middle. When the transmission swing rod 36 rotates, the telescopic and damping support rod 37 provides support without limiting the transmission swing rod 36, thus helping to maintain the angle between its two ends. The rotating base 38 is rotatably connected to the top of the water storage tank 31, allowing the rotating base 38 to drive the mechanical swing arm 33 to rotate on top of the water storage tank 31, thereby changing the spraying direction of the spray pipe 32. In addition, adjusting the extension distance of the mechanical swing arm 33 can also change the spraying direction of the spray pipe 32, so that even in confined spaces, solidifying agent can still be sprayed onto soil contaminated with heavy metals, facilitating subsequent compaction.

[0060] The implementation principle of the soil remediation backfilling and compaction device in this application embodiment is as follows: when compacting soil contaminated by heavy metals, the switch valve 34 of the spraying component 3 can be opened to spray the solidifying agent inside the water storage tank 31 onto the soil contaminated by heavy metals, and then compaction is carried out, thereby improving the compaction efficiency of the soil contaminated by heavy metals.

[0061] Example 2:

[0062] Embodiment 2 of this application discloses a heavy block adjustment component for use in the soil remediation backfilling and compaction device described in Embodiment 1, and includes the following technical features:

[0063] Referring to Figures 7 and 8, the centrifuge component 26 has a first sliding chamber 501 and a second sliding chamber 502 inside. The first sliding chamber 501 extends radially along the fourth transmission wheel 224. The second sliding chamber 502 is connected to one end of the first sliding chamber 501, and the extension direction of the second sliding chamber 502 is perpendicular to the extension direction of the first sliding chamber 501. The extension directions of the first and second sliding chambers form a "T" shape. A centrifuge weight 27 is provided inside the centrifuge component 26, and the centrifuge weight 27 is eccentrically positioned relative to the axis of the fourth transmission wheel 224. The centrifuge weight 27 slides within the first sliding chamber 501, allowing it to slide radially along the fourth transmission wheel 224. A first spring 51 is fixedly installed on the inner wall of the first sliding chamber 501, away from the second sliding chamber 502 and fixedly installed on the centrifuge weight 27. The centrifuge unit 26 is equipped with two weight adjustment components 5, which can control the sliding or fixed state of the centrifuge weight 27 in the first sliding chamber 501. The two weight adjustment components 5 are arranged opposite each other at both ends of the second sliding chamber 502.

[0064] Referring to Figure 8, the weight adjustment assembly 5 includes an adjustment rod 52, an adjustment top rod 53, an adjustment sleeve 54, and an adjustment block 58. The adjustment rod 52 is sleeved on the adjustment top rod 53, the adjustment rod 52 passes through and slides in the adjustment sleeve 54, and the adjustment top rod 53 is rotatably connected to the adjustment sleeve 54.

[0065] Referring to Figures 9 and 10, one end of the adjusting rod 52 is provided with eight triangular grooves 503, and eight protruding sliders 55 are fixed to one end of each of the eight triangular grooves 503 in sequence. One end of the adjusting rod 53 is provided with four inclined sliders 56, which can engage with the triangular grooves 503.

[0066] Referring to Figures 11 and 12, the adjusting sleeve 54 has several first slides 504 and several second slides 505. The depth of the first slides 504 is greater than that of the second slides 505. Eight limiting inclined blocks 57 are provided between the first slides 504 and the second slides 505. The eight limiting inclined blocks 57 can interfere with the engagement state of the inclined slider 56 and the triangular groove 503. The protruding slider 55 slides and engages with the first slide 504 or the second slide 505, and the inclined slider 56 is engaged with the first slide 504 or the second slide 505. The adjusting block 58 is fixedly connected to the adjusting rod 59, and the adjusting top rod 53 is rotatably connected to the adjusting rod 59. The adjusting rod 59 is fixedly installed with the first positioning block 510, and the second positioning block 511 is fixedly installed in the second sliding chamber 502. The adjusting rod 59 slides through the second positioning block 511, and the adjusting block 58 slides and engages with the second sliding chamber 502. A second spring 512 is provided between the first positioning block 510 and the second positioning block 511, and the two ends of the second spring 512 abut against the first positioning block 510 and the second positioning block 511.

[0067] Referring to Figure 12, when the adjusting pressure rod 52 and the adjusting top rod 53 are installed inside the adjusting sleeve 54, due to the restriction of the limiting wedge block 57, the inclined slider 56 and the triangular groove 503 are misaligned, and the inclined slider 56 and the triangular groove 503 are not fully engaged. When it is necessary to reduce the compaction pressure, the adjusting pressure rod 52 is pressed, and the adjusting block 58 is pushed into the second sliding chamber 502 by the adjusting rod 59 and the second spring 512. The adjusting top rod 53 is driven to slide out from the first slide rail 504. When the adjusting top rod 53 slides out from the first slide rail 504, since there is no restriction of the limiting wedge block 57, the inclined slider 56 moves along the tooth groove of the triangular groove 503 and fully engages with it. As the pressing force is withdrawn, the second spring 512 rebounds, causing the adjusting rod 53 to retract. During this retraction, the engagement between the inclined slider 56 and the triangular groove 503 is restricted by the limiting inclined block 57. The limiting inclined block 57 pushes the inclined slider 56, preventing it from returning to the first slide rail 504. Instead, it is pushed to the second slide rail 505 and engages with it. This engagement with the second slide rail 505 fixes the adjusting block 58, which has entered the first sliding chamber 501. Because the second slide rail 505 is shallower, the adjusting block 58, which has entered the first sliding chamber 501, will not completely retract into the second sliding chamber 502. At this point, the adjusting block 58, the centrifugal weight 27, and the first spring 51 are pressed against each other. The centrifugal weight 27, pressed in the middle, cannot generate greater centrifugal force, thus reducing the compaction pressure.

[0068] Referring to Figures 13 and 14, each press and retraction causes the adjusting rod 53 to rotate along the toothed groove of the triangular recess 503. Similarly, when increased compaction pressure is required, the adjusting rod 52 can be pressed again, causing the inclined slider 56 to move away from the second slide rail 505. Without the restriction of the limiting inclined block 57, the inclined slider 56 moves along the toothed groove of the triangular recess 503 and fully engages with it. Releasing the adjusting rod 52 causes the second spring 512 to rebound, and the adjusting rod 53 retracts. During the retraction process, the engagement between the inclined slider 56 and the triangular recess 503 is again restricted by the limiting inclined block 57. The limiting inclined block 57 pushes the inclined slider 56, preventing it from returning to the second slide rail 505, but instead pushing it to the first slide rail 504 and engaging it. When pressing begins, the adjusting block 58 will still move forward into the first sliding chamber 501, but because the first slide rail 504 is deeper, the adjusting block 58 will be driven to completely retract into the second sliding chamber 502. Without the restriction of the adjusting block 58, the centrifugal weight 27 can slide within the first sliding chamber 501. When the centrifugal component 26 rotates, the sliding centrifugal weight 27 will generate a greater centrifugal force, thereby achieving the effect of adjusting the compaction pressure.

[0069] The implementation principle of the weight adjustment component 5 in Embodiment 2 of this application is as follows: When it is necessary to increase the compaction pressure of the compaction equipment to adapt to soil contaminated with heavy metals, the centrifugal component 26 can be rotated first, so that the centrifugal weight 27 inside the centrifugal component 26 presses against the first spring 51. At this time, the adjusting rods 52 on both sides are pressed down, and the adjusting rod 53 will drive the adjusting block 58 from the second sliding chamber 502 into the first sliding chamber 501. At this time, the adjusting block 58 no longer limits the centrifugal weight 27. At this time, the centrifugal weight 27 can slide in the first sliding chamber 501, so that the centrifugal force generated by the centrifugal component 26 during rotation is greater, which is conducive to increasing the compaction pressure of the compaction swing component 24 on the ground. Thus, the compaction efficiency of heavy metal contaminated soil is improved. For ordinary soil, the adjusting lever 52 can be pressed again to allow the adjusting block 58 to enter the first sliding chamber 501 and limit the centrifugal weight 27, so that the centrifugal weight 27 can no longer slide in the first sliding chamber 501, thereby reducing the compaction pressure of the compaction swinging component 24 on the ground.

[0070] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
