Description

Technical Field

[0001] This invention relates to the field of highway construction technology, specifically to a modified soil compaction device for highway construction. Background Technology

[0002] Improved soil is divided into physically improved soil and chemically improved soil. Physical improvement is achieved by adding crushed stone or other materials to change the particle size, while chemical improvement is achieved by adding solidifying agents such as lime, cement, and fly ash to improve the engineering performance of the soil.

[0003] Current highway construction soil compaction equipment often suffers from several drawbacks. During compaction, the compaction plate forces the mixed soil downwards. When the plate rapidly contacts the soil, stones at the edges tend to fly outwards, potentially injuring personnel or damaging the equipment on either side. Furthermore, the mixed soil can be scattered far and wide, wasting material. Before compaction, amendment materials need to be added to the soil. Direct compaction can lead to stratification between the amendment material and the original soil. If more material is added to certain areas, the resulting uneven contact height between the compaction plate and the soil can negatively impact the compaction effect. Summary of the Invention

[0005] A base plate, a fixed box is fixedly connected to the top of the base plate, a base is fixedly connected to the top of the fixed box, a control mechanism is fixedly connected inside the base, and a first slide is provided inside the fixed box;

[0006] A protective mechanism for blocking stones that fly to both sides. The protective mechanism includes a first rotating shaft, a connecting rod fixedly connected to the outside of the first rotating shaft, a first elastic rod fixedly connected to the outside of the first rotating shaft and away from the connecting rod, a backing plate fixedly connected to the outside of the first elastic rod, and a locking post fixedly connected to the outside of the backing plate.

[0008] Preferably, the fixed box is externally fixedly connected to an angle plate, the bottom of the angle plate is fixedly connected to an electric push rod, the bottom of the electric push rod is fixedly connected to a pointed rod, which is used to reinforce the position of the equipment when adjusting the direction of the compaction mechanism, and the bottom of the fixed box is provided with pulleys.

[0009] Preferably, the control mechanism includes an electric telescopic bending rod, the bottom of which is fixedly connected to a sliding box, the bottom of which is fixedly connected to a support plate, and a second slide is provided inside the first slide. The electric telescopic bending rod is fixedly connected inside the base.

[0010] Preferably, an adjusting rod is fixedly connected to the outside of the sliding box, a fixing ring is fixedly connected to the outside of the adjusting rod, the fixing ring is rotatably connected to the first rotating shaft, a telescopic tube is fixedly connected to the inside of the sliding box, and a nozzle is fixedly connected to the outside of the telescopic tube.

[0011] Preferably, a slide plate is slidably connected inside the second slide rail, a support plate is fixedly connected to the outside of the slide plate, and a first spring is fixedly connected to the bottom of the slide plate.

[0012] Preferably, a second spring is fixedly connected to the bottom of the fixing ring, a first retaining seat is fixedly connected to the bottom of the second spring, and an arc-shaped plate is fixedly connected to the bottom of the first retaining seat.

[0013] Preferably, the arc-shaped plate has a circular groove inside, a locking ring is fixedly connected inside the circular groove, a suspension column is engaged inside the locking ring, and a soft plate is sleeved on the outside of the suspension column to slow down the movement of the stone and promote the stone to bounce back to the center position.

[0014] Preferably, a compacted lower plate is fixedly connected to the bottom of the vertical plate, and a compacted upper plate is fixedly connected to the top of the vertical plate. A fixed frame is fixedly connected to the top of the compacted upper plate to enclose the improved soil and the improved material together.

[0015] Preferably, a second rotating shaft is rotatably connected inside the fixed frame, and a rolling roller is sleeved on the outside of the second rotating shaft. An inclined plate is fixedly connected to the outside of the second rotating shaft. When in contact with the improved soil, the inclined plate and the second elastic rod are squeezed, gradually driving the second rotating shaft to rotate, and then driving the rolling roller to rotate, so as to roll the improved soil and improved material at the bottom. A second elastic rod is fixedly connected to the outside of the inclined plate, and the second elastic rod is fixedly connected to the top of the compaction plate.

[0016] Preferably, the air supply assembly includes a second bracket, a rubber air bag is fixedly connected to the bottom of the second bracket, an air outlet pipe is fixedly connected to the outside of the rubber air bag, and the second bracket is fixedly connected to the outside of the third spring.

[0017] This invention provides an improved soil compaction device for highway construction. It has the following beneficial effects:

[0018] 1. The soil compaction equipment used in this highway construction project, through the installation of control, protection, and compaction mechanisms, employs two compaction methods: rolling and compaction to mix the improved soil with the improvement materials. During compaction, the sides of the compaction plate are protected to prevent stones from flying to the sides, while also protecting the materials. This achieves the goal of facilitating the compaction of the improved soil.

[0019] 2. The improved soil compaction equipment used in this highway construction project controls the compaction height through a control mechanism. This mechanism smoothly controls the height of the protective and compaction mechanisms, and allows for simple cleaning of the exterior of the upper and lower compaction plates before and after compaction to remove dust. This achieves the goal of easily controlling the height of the protective and compaction mechanisms.

[0020] 3. The soil compaction equipment used in this highway construction employs a protective mechanism on both sides of the compaction plate. During compaction, the compaction plate presses downwards onto the mixed improved soil. When the compaction plate rapidly contacts the improved soil, stones at the edges of the plate are prone to splashing outwards, potentially injuring personnel or equipment on either side of the equipment. Furthermore, the mixed improved soil can easily be thrown far away, wasting materials. Therefore, the protective mechanism on both sides provides rebound protection for the stones, thus solving these problems and achieving the goal of reducing stone splashing during compaction.

[0021] 4. The soil compaction equipment used in this highway construction project compacts the improved soil through a compaction mechanism. Before compacting the improved soil, amendment materials need to be added. If compacted directly, the amendment materials can easily separate from the original improved soil. If more material is added in a certain area, it will result in a significant difference in the height of that area, leading to uneven contact between the compaction plate and the improved soil, thus affecting the compaction effect. Therefore, an upper compaction plate and a lower compaction plate are used. The upper compaction plate is used to compact the surface of the improved soil, and then the lower compaction plate is used for a second compaction to solve the above problems. This achieves the goal of facilitating the compaction of the improved soil. Attached Figure Description

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0033] like Figures 1-9 As shown, the present invention provides a technical solution, specifically including:

[0034] The base plate 1 has a fixed box 2 fixedly connected to the top of the base plate 1, a base 3 fixedly connected to the top of the fixed box 2, a control mechanism 4 fixedly connected inside the base 3, and a first slide rail 11 opened inside the fixed box 2.

[0035] The protective mechanism 5 is used to block stones that fly to both sides. The protective mechanism 5 includes a first rotating shaft 501. A connecting rod 502 is fixedly connected to the outside of the first rotating shaft 501. A first elastic rod 503 is fixedly connected to the outside of the first rotating shaft 501 and away from the connecting rod 502. A backing plate 504 is fixedly connected to the outside of the first elastic rod 503. A locking post 505 is fixedly connected to the outside of the backing plate 504. The first rotating shaft 501 is rotatably connected inside the control mechanism 4.

[0036] The compaction mechanism 6 is used to compact improved soil. The compaction mechanism 6 includes a vertical plate 601, a partition plate 602 is fixedly connected to the outside of the vertical plate 601, a third spring 603 is fixedly connected to the bottom of the partition plate 602, an air supply assembly 604 is fixedly connected to the bottom of the third spring 603, and the vertical plate 601 is fixedly connected to the outside of the connecting rod 502.

[0037] An external corner plate 7 is fixedly connected to the fixed box 2. An electric push rod 8 is fixedly connected to the bottom of the corner plate 7. A pointed rod 9 is fixedly connected to the bottom of the electric push rod 8. A pulley 10 is provided at the bottom of the fixed box 2. A power system is provided inside the base plate 1.

[0038] Before using the equipment, adjust the control mechanism 4 and the compaction mechanism 6, and place the equipment in its initial position. Turn on the control mechanism 4 and perform a simple cleaning of the compaction mechanism 6. Then, control the control mechanism 4, the protective mechanism 5, and the compaction mechanism 6, and control the entire equipment to move forward for the first compaction operation. After completion, control the equipment to reverse and turn on the control mechanism 4, the protective mechanism 5, and the compaction mechanism 6 again for a second compaction of the improved soil. After the second operation, control the control mechanism 4 again and perform a simple cleaning of the compaction mechanism 6.

[0039] The control mechanism 4 includes an electric telescopic bending rod 401. A sliding box 402 is fixedly connected to the bottom of the electric telescopic bending rod 401. A fan is installed inside the sliding box 402. The sliding box 402 is slidably connected inside the first slide rail 11. A support plate 406 is fixedly connected to the bottom of the first slide rail 11. A second slide rail 410 is opened inside the first slide rail 11. The electric telescopic bending rod 401 is fixedly connected inside the base 3.

[0040] An adjusting rod 403 is fixedly connected to the outside of the sliding box 402. A fixing ring 404 is fixedly connected to the outside of the adjusting rod 403. The fixing ring 404 is rotatably connected to the first rotating shaft 501. Two adjusting rods 403 and two fixing rings 404 are provided and symmetrically arranged. A telescopic pipe 405 is fixedly connected to the inside of the sliding box 402. A nozzle 411 is fixedly connected to the outside of the telescopic pipe 405. When the fan and the nozzle 411 are turned on, air can be supplied to clean the bottom of the compaction plate to remove dust.

[0041] When the electric telescopic bending rod 401 is activated, the electric telescopic bending rod 401 drives the sliding box 402 to slide downward inside the first slide rail 11. The sliding box 402 drives the external adjusting bending rod 403 and the fixing ring 404 to move downward, thereby driving the protective mechanism 5 and the compaction mechanism 6 to move downward.

[0042] The second slide 410 has a sliding plate 407 inside, a support plate 408 is fixedly connected to the outside of the sliding plate 407, and a first spring 409 is fixedly connected to the bottom of the sliding plate 407. The first spring 409 is fixedly connected to the support plate 406.

[0043] As the sliding box 402 moves downward, the telescopic tube 405 follows the sliding box 402 downward and presses down on the support plate 408 and the first spring 409. The support plate 408 moves downward inside the second slide rail 410 until the support plate 408 contacts the bottom support plate 406. There is a distance between the telescopic tube 405 and the support plate 406 to prevent the telescopic tube 405 from being damaged.

[0044] The locking post 505 is engaged inside the fixing ring 404. The bottom of the fixing ring 404 is fixedly connected to a second spring 506. The bottom of the second spring 506 is fixedly connected to a first locking seat 507. The bottom of the first locking seat 507 is fixedly connected to an arc-shaped plate 508.

[0045] When it is necessary to change the compaction method, manually pull the backing plate 504 outward. The backing plate 504 drives the first elastic rod 503 to move outward until the locking post 505 disengages from the fixing ring 404. Manually flip the backing plate 504, which drives the first elastic rod 503 to rotate. This, in turn, drives the first rotating shaft 501 and connecting rod 502 outside the first elastic rod 503 to rotate. The connecting rod 502 drives the entire compaction mechanism 6 to rotate, thereby changing the compaction method. Then, manually press the locking post 505 into the inside of the fixing ring 404 for fixation.

[0046] The inside of the arc plate 508 is provided with a circular groove 509. A locking ring 510 is fixedly connected inside the circular groove 509. A suspension column 511 is engaged inside the locking ring 510. A flexible plate 512 is sleeved on the outside of the suspension column 511.

[0047] As the control mechanism 4 drives the protective mechanism 5 and the compaction mechanism 6 to move downward, the second spring 506 moves downward along with the first fixed ring 404, which in turn drives the first card seat 507, the arc plate 508 and the suspension column 511 at the bottom of the second spring 506 to move downward until the arc plate 508 lands on the improved soil. As the compaction mechanism 6 squeezes the improved soil, the edge stones fly to both sides and land on the soft plate 512 outside the suspension column 511. After the stones are embedded in the soft plate 512, they slowly bounce back to the middle position.

[0048] As the electric telescopic bending rod 401 closes, the control mechanism 4 gradually drives the protective mechanism 5 and the compaction mechanism 6 to move upward. At this time, the second spring 506 moves upward as well. After returning to its original length, it is stretched due to the weight of the bottom equipment. During the deformation process, it will drive the bottom arc plate 508 to vibrate, promoting the downward movement of dust attached to the soft plate 512 and the outside of the arc plate 508.

[0049] The bottom of the vertical plate 601 is fixedly connected to a compacting lower plate 605, the top of the vertical plate 601 is fixedly connected to a compacting upper plate 606, and the top of the compacting upper plate 606 is fixedly connected to a fixing frame 607.

[0050] The fixed frame 607 is rotatably connected to a second rotating shaft 608, which passes through the interior of the fixed frame 607. A rolling roller 609 is sleeved on the outside of the second rotating shaft 608. An inclined plate 610 is fixedly connected to the outside of the second rotating shaft 608. A second elastic rod 611 is fixedly connected to the outside of the inclined plate 610. The second elastic rod 611 is fixedly connected to the top of the compaction plate 606.

[0051] In the initial state, the compaction plate 606 is vertically downward. After the control mechanism 4 is activated, the control mechanism 4 drives the entire compaction mechanism 6 to move downward, which in turn drives the compaction plate 606 to move downward. At this time, the fixed frame 607 encircles the improved soil to be compacted. The inclined plate 610 is gradually squeezed in contact with the improved soil. The inclined plate 610 begins to squeeze the second elastic rod 611 until the inclined plate 610 is in a horizontal state. At this time, the inclined plate 610 drives the second rotating shaft 608 to rotate, which in turn drives the rolling roller 609 outside the second rotating shaft 608 to rotate, and compacts the improved soil at the bottom.

[0052] By adjusting the protective mechanism 5, the compaction plate 605 is positioned vertically downwards. After activating the control mechanism 4, the control mechanism 4 drives the entire compaction mechanism 6 downwards, which in turn drives the compaction plate 605 downwards to perform the compaction work.

[0053] The air supply assembly 604 includes a second bracket 6041, a rubber air bag 6042 is fixedly connected to the bottom of the second bracket 6041, an air outlet pipe 6043 is fixedly connected to the outside of the rubber air bag 6042, and the second bracket 6041 is fixedly connected to the outside of the third spring 603.

[0054] During the rising or falling of the compaction mechanism 6, the third spring 603 begins to drive the second card seat 6041 at the bottom and the rubber air bag 6042 to move. When the rubber air bag 6042 collides with the upper compaction plate 606 or the lower compaction plate 605, the gas moves outward through the air outlet pipe 6043, which can drive the dust attached to the upper surface of the upper compaction plate 606 or the lower compaction plate 605 outward, preventing dust accumulation and increasing the weight of the equipment.

[0055] Working Principle: Before using the equipment, adjust the control mechanism 4 and the compaction mechanism 6, and place the equipment in the initial position. Repeatedly activate the electric telescopic bending rod 401. The electric telescopic bending rod 401 drives the sliding box 402 to slide downward inside the first slide rail 11. The sliding box 402 drives the external adjusting bending rod 403 and the fixing ring 404 to move downward, thereby driving the protective mechanism 5 and the compaction mechanism 6 to move downward. During the downward movement of the sliding box 402, the telescopic tube 405 follows the sliding box 402 downward and presses down on the support plate 408 and the first spring 409. The support plate 408 moves downward inside the second slide rail 410 until the support plate 408 contacts the bottom support plate 406. There is a distance between the telescopic tube 405 and the support plate 406 to prevent damage to the telescopic tube 405.

[0056] Activate control mechanism 4 to perform a simple cleaning of the compacted upper plate 606. Activate the blower and nozzle 411 to supply air to the bottom of the compacted plate for cleaning, thus removing dust.

[0057] Subsequently, the control mechanism 4, the protective mechanism 5, and the compaction mechanism 6 are activated, and the entire equipment is moved forward to perform the first compaction operation. The electric telescopic bending rod 401 is activated, causing the sliding box 402 to slide downwards inside the first slide rail 11. The sliding box 402 then moves the external adjusting bending rod 403 and the fixing ring 404 downwards, which in turn moves the protective mechanism 5 and the compaction mechanism 6 downwards. Initially, the compaction plate 606 is vertically downwards. After the control mechanism 4 is activated, it moves the entire compaction mechanism 6 downwards, which in turn moves the compaction plate 606 downwards. At this time, the fixing frame 607 completely encircles the improved soil to be compacted. The inclined plate 610 is gradually compressed in contact with the improved soil, and it begins to compress the second elastic rod 611 until it is horizontal. At this point, the inclined plate 610 drives the second rotating shaft 608 to rotate, which in turn drives the external rolling roller 609 to rotate, compacting the improved soil at the bottom.

[0058] As the control mechanism 4 drives the protective mechanism 5 and the compaction mechanism 6 to move downward, the second spring 506 moves downward along with the first fixed ring 404, which in turn drives the first card seat 507, the arc plate 508 and the suspension column 511 at the bottom of the second spring 506 to move downward until the arc plate 508 lands on the improved soil. As the compaction mechanism 6 squeezes the improved soil, the edge stones fly to both sides and land on the soft plate 512 outside the suspension column 511. After the stones are embedded in the soft plate 512, they slowly bounce back to the middle position.

[0059] As the electric telescopic bending rod 401 closes, the control mechanism 4 gradually drives the protective mechanism 5 and the compaction mechanism 6 to move upward. At this time, the second spring 506 moves upward as well. After returning to its original length, it is stretched due to the weight of the bottom equipment. During the deformation process, it will drive the bottom arc plate 508 to vibrate, promoting the downward movement of dust attached to the soft plate 512 and the outside of the arc plate 508.

[0060] During the rising or falling of the compaction mechanism 6, the third spring 603 begins to drive the second card seat 6041 at the bottom and the rubber air bag 6042 to move. When the rubber air bag 6042 collides with the upper compaction plate 606 or the lower compaction plate 605, the gas moves outward through the air outlet pipe 6043, which can drive the dust attached to the upper surface of the upper compaction plate 606 or the lower compaction plate 605 outward, preventing dust accumulation and increasing the weight of the equipment.

[0061] After completion, the control equipment reverses and restarts the control mechanism 4, protection mechanism 5, and compaction mechanism 6 to perform a second compaction of the improved soil after the first compaction. The electric telescopic boom 401 is activated, causing the sliding box 402 to slide downwards inside the first slide rail 11. The sliding box 402 then moves the external adjusting boom 403 and fixing ring 404 downwards, which in turn moves the protection mechanism 5 and compaction mechanism 6 downwards.

[0062] Manually pull the backing plate 504 outwards. The backing plate 504 drives the first elastic rod 503 outwards until the locking post 505 disengages from the fixing ring 404. Manually flip the backing plate 504, causing it to rotate the first elastic rod 503. This, in turn, causes the first rotating shaft 501 and connecting rod 502 outside the first elastic rod 503 to rotate. The connecting rod 502 then rotates the entire compaction mechanism 6, causing the lower compaction plate 605 to be in a vertically downward position, thus changing the compaction method. Then, manually press the locking post 505 into the fixing ring 404 for fixation.

[0063] After the control mechanism 4 is activated, the control mechanism 4 drives the entire compaction mechanism 6 to move downward, which in turn drives the compaction plate 605 to move downward to carry out the compaction work.

[0064] After the second operation is completed, control mechanism 4 can be turned on again to perform a simple cleaning of the compacted lower plate 605. Turning on the blower and nozzles 411 can provide airflow to clean the bottom of the compacted plate, thus removing dust.
