Description

Technical Field

[0001] This invention relates to the field of land compaction technology, specifically a portable soil compaction device for civil engineering. Background Technology

[0002] In civil engineering, it is often necessary to level and compact the foundation to improve the soil's bearing capacity, reduce its compressibility, and thus increase its stability. A ramming device utilizes the impact and vibration it generates to compact the soil. The use of a ramming device typically involves placing the ramming head on the surface of the land to be treated, ensuring close contact between the ramming head and the ground. The operating frequency and impact force of the ramming device are then set according to the specific work requirements.

[0003] Currently, in practical use, ramming equipment typically requires one person to hold the device to ensure its overall stability, while another person guides it along a predetermined trajectory using a traction rope. This requires at least two people working together. Furthermore, during building construction, soil ramming often results in a large amount of dust being stirred up, seriously affecting the health of workers. Although existing equipment includes dust suppression mechanisms, water mist dust suppression wets the soil, impacting the work. Air extraction dust suppression often involves centralized dust disposal after the machine is shut down, resulting in dust being dispersed to distant locations, which still generates significant dust during this process. Therefore, to address these issues, a portable ramming device for civil engineering is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a portable ramming device for civil engineering to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: As an alternative solution to the portable ramming device for civil engineering described in this invention, the portable ramming device for civil engineering includes a support frame, ramming equipment, and moving wheels. A soil compaction device for compacting the soil is installed in the center of the support. The outer side of the bracket is also equipped with symmetrically arranged casters; A dust collection module for dust suppression is installed on one side of the bracket, and a handle that is fixedly connected to the bracket is provided above the dust collection module. Above the support is a soil cleaning module for cleaning the bottom of the rammed earth equipment. The bottom of the support is equipped with a soil clod breaking module for breaking up soil clods; The dust recovery module includes an installation box, a first air pump, and a filter screen. One side of the installation box is fixedly connected to a bracket. The first air pump is installed inside the installation box, and the input end of the first air pump is provided with an inclined filter screen that is fixedly connected to the installation box. A first vibration plate is fixedly connected to the outside of the filter screen. An air inlet pipe is also installed on one side of the mounting box, and multiple sets of air inlets are installed on the inner side of the air inlet pipe, with the air inlets located on the outer side of the compaction part of the ramming equipment. The installation box contains a first hydraulic rod, the free end of which is fixedly connected to an extrusion plate, and the top of the extrusion plate is fixedly connected to a dustproof plate. The outer side of the dustproof plate is slidably connected to the installation box. The installation box is also equipped with a second hydraulic rod, and the free end of the second hydraulic rod is fixedly connected to a molding frame. The outer side of the molding frame is fixedly connected to a second vibration plate that is inclined. A first motor is installed on one side of the interior of the mounting box, and a rotating shaft is fixedly connected to the end of the main shaft of the first motor. Evenly distributed rotating plates are fixedly connected to the outside of the rotating shaft. A connecting shaft is installed on the other side of each rotating plate, and a striking plate is rotatably connected to the outside of each connecting shaft.

[0006] As an optional embodiment of the portable ramming device for civil engineering described in this invention, the installation box is further equipped with a water mist spraying device.

[0007] As an alternative embodiment of the portable ramming device for civil engineering described in this invention, the air inlet pipe is Y-shaped.

[0008] As an optional embodiment of the portable ramming device for civil engineering described in this invention, the bottom of the forming frame is open, the frame edge is C-shaped, a baffle plate is fixedly connected to one side of the forming frame, and the outer side of the baffle plate is slidably connected to the mounting box.

[0009] Currently, in practical use, rammed earth equipment typically requires at least two people: one to hold the device and ensure its stability, and another to guide it along a predetermined path using a traction rope. Furthermore, during construction, the ramming process often generates significant amounts of dust, seriously impacting the health of workers. While existing equipment includes dust suppression mechanisms, water mist dust suppression wets the soil, affecting work. Air extraction dust suppression often involves centralized dust disposal after shutdown, resulting in dust being dispersed over long distances, which still generates considerable dust during this process. This invention, however, allows for easy movement of the rammed earth equipment by using a hand-held handle to move the support frame. No manual traction is required, and it can be operated by a single person. During ramming, the generated dust is drawn into the installation area by a first air pump. Inside the box, dust is filtered by a filter screen. Simultaneously, a water mist sprayer periodically sprays water. Once dust accumulates to a certain level, a first hydraulic rod drives an extrusion plate to compress the dust, shaping it for direct discharge and preventing dust re-entrainment. Before compression, a first motor rotates a shaft, causing a rotating plate to rotate a connecting shaft. This shaft, in turn, rotates a striking plate, striking a first vibrating plate to facilitate dust falling and ensure thorough treatment. After the dust is compressed, a second hydraulic rod moves the forming frame away from the mounting box. This frame then moves a second vibrating plate. Once the frame is outside the mounting box, the striking plate engages with the second vibrating plate to facilitate the falling of the shaped dust blocks inside, ensuring efficient dust removal.

[0010] As an optional embodiment of the portable soil compaction device for civil engineering described in this invention, the soil clod crushing module includes a mounting frame, a second motor, and a crushing rod. The outer side of the mounting frame is fixedly connected to a support, and the second motor is fixedly connected to the outer side of the mounting frame. The crushing rod is fixedly connected to the end of the main shaft of the second motor. Multiple sets of crushing blades are installed on the outer side of the crushing rod, and the other end of the crushing rod is rotatably connected to a mounting base. The outer side of the mounting base is fixedly connected to the mounting frame.

[0011] As an alternative embodiment of the portable ramming device for civil engineering described in this invention, the ramming blades are arranged in a curved configuration.

[0012] During compaction work, large soil clods on the soil surface will affect the compaction efficiency and quality of the ramming equipment. When the ramming equipment moves, the second motor at the bottom of its support drives the crushing rod to rotate, which in turn drives the crushing blades to rotate. The crushing blades can break up the larger soil clods, which helps to improve the compaction quality and efficiency of the subsequent ramming equipment.

[0013] As an optional embodiment of the portable ramming device for civil engineering described in this invention, the soil clearing module includes a fixed frame, a second air pump, and a hose. The outer side of the fixed frame is fixedly connected to the support. The second air pump is installed inside the fixed frame. The output end of the second air pump is connected to the hose, and the other end of the hose is connected to the swing tube.

[0014] As an alternative embodiment of the portable ramming device for civil engineering described in this invention, the outer side of the swing tube is rotatably connected to a rotating shaft, and the other end of the rotating shaft is fixedly connected to the fixed frame.

[0015] As an optional embodiment of the portable ramming device for civil engineering described in this invention, a reciprocating mechanism is fixedly connected inside the fixed frame, and a sliding sleeve is fixedly connected to the free end of the reciprocating mechanism. The interior of the sliding sleeve is slidably connected to the swing tube.

[0016] During the compaction process, soil may adhere to the bottom of the compaction plate, affecting the compaction quality. In this case, a second air pump drives high-pressure air to be discharged through the swing pipe, which can clean the bottom of the compaction equipment and play a positive role in soil compaction. During cleaning, the reciprocating mechanism is activated to move the sliding sleeve back and forth, and the swing pipe swings back and forth under the action of the rotating shaft, thus ensuring that the discharge end of the swing pipe swings, thereby ensuring that a large area of ​​the bottom of the compaction equipment is cleaned.

[0017] Compared with the prior art, the beneficial effects of the present invention are: When in use, the support is moved by hand-held handle, which is very convenient for moving the ramming equipment. No manual traction is required and it can be operated by a single person. During ramming, the dust generated is sucked into the installation box by the first air pump and filtered by the filter screen. At the same time, the water mist spraying device sprays every once in a while. After the dust accumulates to a certain extent, the first hydraulic rod drives the extrusion plate to compress the dust and shape it for easy direct discharge and avoid dust. Before extrusion molding, the first motor is started to drive the rotating shaft to rotate, which in turn drives the connecting shaft to rotate. The connecting shaft then drives the striking plate to rotate, which in turn strikes the first vibrating plate to facilitate the dust falling and ensure that the dust is fully treated. After the dust is compressed into shape, the second hydraulic rod can be activated to move the forming frame and detach it from the mounting box. At this time, the forming frame moves the second vibrating plate. When the forming frame moves to the outside of the mounting box, its striking plate cooperates with the second vibrating plate to facilitate the falling of the formed dust block inside the forming frame, so that the dust can be fully utilized. During compaction work, large soil clods on the soil surface will affect the compaction efficiency and quality of the compaction equipment. When the compaction equipment moves, the second motor at the bottom of its support drives the crushing rod to rotate, which in turn drives the crushing blades to rotate. The crushing blades can break up the larger soil clods, which helps to improve the compaction quality and efficiency of the subsequent compaction equipment. During the compaction process, soil may adhere to the bottom of the compaction plate, affecting the compaction quality. In this case, a second air pump drives high-pressure air to be discharged through the swing pipe, which can clean the bottom of the compaction equipment and play a positive role in the compaction of the soil. Furthermore, during the cleaning process, the reciprocating mechanism is activated to move the sliding sleeve back and forth, which in turn drives the swing tube to swing back and forth under the action of the rotating shaft, thereby ensuring that the discharge end of the swing tube swings, thus ensuring that the bottom of the rammed earth equipment is cleaned over a large area.

[0019] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The present invention provides a technical solution: A portable ramming device for civil engineering includes a support frame 1, a ramming device 2, and wheels 3. A soil compaction device 2 for compacting the soil is installed in the center of the aforementioned support 1; The outer side of the aforementioned bracket 1 is also equipped with symmetrically arranged movable wheels 3; A dust collection module 5 for dust suppression is installed on one side of the aforementioned bracket 1, and a handle 4 is fixedly connected to the bracket 1 above the aforementioned dust collection module 5. Above the aforementioned support 1, a soil cleaning module 7 for cleaning the bottom of the rammed earth equipment 2 is also installed; The bottom of the aforementioned support 1 is equipped with a soil clod breaking module 6 for breaking up soil clods; The dust collection module 5 includes a mounting box 501, a first air pump 502, and a filter screen 503. One side of the mounting box 501 is fixedly connected to the bracket 1. The first air pump 502 is installed inside the mounting box 501, and the input end of the first air pump 502 is provided with an inclined filter screen 503 fixedly connected to the mounting box 501. A first vibration plate 509 is fixedly connected to the outside of the filter screen 503. An air inlet pipe 507 is also installed on one side of the aforementioned mounting box 501, and multiple sets of air inlets 508 are installed on the inner side of the air inlet pipe 507, and the air inlets 508 are located on the outer side of the compaction part of the ramming equipment 2. The mounting box 501 is equipped with a first hydraulic rod 504. The free end of the first hydraulic rod 504 is fixedly connected to an extrusion plate 505, and the top of the extrusion plate 505 is fixedly connected to a dustproof plate 506. The outer side of the dustproof plate 506 is slidably connected to the mounting box 501. The installation box 501 is also equipped with a second hydraulic rod 510, and the free end of the second hydraulic rod 510 is fixedly connected to a molding frame 511. The outer side of the molding frame 511 is fixedly connected to a second vibration plate 512 that is inclined. The first motor 513 is installed on one side of the interior of the mounting box 501, and a rotating shaft 514 is fixedly connected to the end of the main shaft of the first motor 513. A rotating plate 515 is fixedly connected to the outer side of the rotating shaft 514. A connecting shaft 516 is installed on the other side of the rotating plate 515. A striking plate 517 is rotatably connected to the outer side of the connecting shaft 516.

[0020] The aforementioned installation box 501 is also equipped with a water mist spraying device 518.

[0021] The aforementioned intake pipe 507 is Y-shaped.

[0022] The bottom of the molding frame 511 is open, the frame of the molding frame 511 is C-shaped, and a baffle plate 519 is fixedly connected to one side of the molding frame 511. The outer side of the baffle plate 519 is slidably connected to the mounting box 501.

[0023] Currently, in practical use, ramming equipment typically requires at least two people: one to hold the device and ensure its stability, and another to guide it along a predetermined path using a traction rope. Furthermore, during soil compaction in building construction, a large amount of dust is often generated, seriously affecting the health of workers. While existing equipment includes dust suppression mechanisms, water mist dust suppression wets the soil, impacting work. Air extraction dust suppression often involves centralized dust disposal after shutdown, resulting in dust being dispersed over long distances, still generating significant dust during this process. In contrast, this invention allows for easy movement of the ramming equipment 2 by using a hand-held handle 4 to move the support 1. No manual traction is required, and it can be operated by a single person. During compaction, the generated dust is drawn into the mounting box 501 by the first air pump 502 and filtered by the filter screen 503. Additionally, dust is filtered periodically. The water mist spraying device 518 sprays water. After the dust accumulates to a certain extent, the first hydraulic rod 504 drives the extrusion plate 505 to extrude the dust into shape, which is convenient for subsequent direct discharge and avoids dust. Before extrusion, the first motor 513 drives the rotating shaft 514 to rotate, which in turn drives the rotating plate 515 to drive the connecting shaft 516 to rotate. The connecting shaft 516 then drives the striking plate 517 to rotate, which in turn strikes the first vibrating plate 509 to facilitate the dust falling and ensure that the dust is fully treated. After the dust is extruded into shape, the second hydraulic rod 510 drives the forming frame 511 to move and detach from the mounting box 501. At this time, the forming frame 511 drives the second vibrating plate 512 to move. When the forming frame 511 moves to the outside of the mounting box 501, its striking plate 517 cooperates with the second vibrating plate 512 to facilitate the falling of the formed dust block inside the forming frame 511, so that the dust can be fully utilized. In this embodiment, the support 1 can be moved precisely by the staff holding the handle 4. Compared with the traditional traction rope movement, its movement direction is more convenient and precise. Since the multiple air inlets 508 inside the air inlet pipe 507 are located outside the ramming part of the ramming equipment 2, they can effectively play the role of dust suction. The inclined filter screen 503 can play the role of filtering, and dust is not easy to accumulate on the surface. Before the dust is squeezed, the striking plate 517 is rotatably connected to the connecting shaft 516. This avoids excessive squeezing between the striking plate 517 and the first vibrating plate 509. The striking plate 517 can self-adapt to the impact, ensuring normal operation of the equipment and smooth dust fall. The first hydraulic rod 504 drives the extrusion plate 505 to cooperate with the forming frame 511, thus squeezing the dust into shape. To ensure that the shape is not loose, the water mist spraying device 518 can spray intermittently to ensure that the dust adheres to the shape. The dustproof plate 506 can prevent the dust from being on the other side of the extrusion plate 505 and affecting the reset action of the first hydraulic rod 504. After extrusion molding, the second hydraulic rod 510 drives the molding frame 511 to move. The molding frame 511 works in conjunction with the extrusion plate 505. At this time, the molding frame 511 can move the molded dust block to the outside of the mounting box 501, and the second vibration plate 512 moves along with it. At this time, in conjunction with the striking plate 517, it can vibrate the inside of the molding frame 511, which helps the dust block fall directly onto the soil surface and can be used directly. At the same time, it avoids dust generated by subsequent dust treatment. The baffle plate 519 can prevent the dust from being located on one side of the molding frame 511 and affecting its reset. After the molding frame 511 is reset, its second vibration plate 512 will not contact the striking plate 517. Compared to traditional compaction devices, this device is safer and more reliable because it keeps workers away from the compaction equipment 2, preventing the equipment from tipping over and injuring them. The distance also reduces the impact of dust on workers, keeping them away from the source of dust.

[0024] Example 2: This example is an improvement on Example 1. Please refer to Example 1. Figure 7 Specifically, the aforementioned soil clod crushing module 6 includes a mounting frame 601, a second motor 602, and a crushing rod 603. The outer side of the mounting frame 601 is fixedly connected to the bracket 1. The second motor 602 is fixedly connected to the outer side of the mounting frame 601. The crushing rod 603 is fixedly connected to the end of the main shaft of the second motor 602. Multiple sets of crushing blades 604 are installed on the outer side of the crushing rod 603. The other end of the crushing rod 603 is rotatably connected to a mounting base 605. The outer side of the mounting base 605 is fixedly connected to the mounting frame 601.

[0025] The aforementioned breaking blade 604 is bent.

[0026] During the compaction work, large soil clods on the soil surface will affect the compaction efficiency and quality of the ramming equipment 2. When the ramming equipment 2 moves, the second motor 602 set at the bottom of its support 1 drives the breaking rod 603 to rotate, and the breaking rod 603 drives the breaking blade 604 to rotate. The breaking blade 604 can break up the larger soil clods, which helps to improve the compaction quality and efficiency of the ramming equipment 2. In this embodiment, when the support 1 and the ramming device 2 are moving, their breaking blades 604 make contact with the protruding soil blocks in the subsequent moving area in advance, and the soil blocks can be broken up by the rotation of the breaking blades 604, ensuring the subsequent soil compaction work. The breaking blades 604 are curved, which can increase the breaking area of ​​the soil blocks, ensuring that the soil blocks are fully broken up, which helps the subsequent compaction work.

[0027] Example 3: This example is an improvement on Example 2. Please refer to [link / reference]. Figure 8 Specifically, the aforementioned soil clearing module 7 includes a fixed frame 701, a second air pump 702, and a hose 703. The outer side of the fixed frame 701 is fixedly connected to the bracket 1. The second air pump 702 is installed inside the fixed frame 701. The output end of the second air pump 702 is connected to the hose 703, and the other end of the hose 703 is connected to the swing tube 704.

[0028] The outer side of the aforementioned swing tube 704 is rotatably connected to a rotating shaft 707, and the other end of the rotating shaft 707 is fixedly connected to the fixed frame 701.

[0029] The fixed frame 701 is internally fixedly connected to a reciprocating mechanism 706, and the free end of the reciprocating mechanism 706 is fixedly connected to a sliding sleeve 705. The interior of the sliding sleeve 705 is slidably connected to the swing tube 704.

[0030] During the compaction process of the ramming equipment 2, soil may adhere to the bottom of the compaction plate, affecting the compaction quality. In this case, the second air pump 702 drives high-pressure air to be discharged through the swing pipe 704, which can clean the bottom of the ramming equipment 2 to a certain extent and play a positive role in the compaction of the soil. During the cleaning process, the reciprocating mechanism 706 is activated to drive the sliding sleeve 705 to move back and forth. Under the action of the rotating shaft 707, the swing pipe 704 swings back and forth, thereby ensuring that the discharge end of the swing pipe 704 swings, thus ensuring that a large area of ​​the bottom of the ramming equipment 2 is cleaned. In this embodiment, the flexible hose 703 ensures that the swing tube 704 can swing back and forth. One end of the swing tube 704 can be cleaned by high-pressure gas at the bottom of the ramming part of the ramming equipment 2, ensuring the ramming quality of the soil by the ramming equipment 2. The rotating shaft 707 ensures that the swing tube 704 swings back and forth around the rotating shaft 707, thereby ensuring the cleaning quality of the bottom of the ramming equipment 2.
