Description

Technical Field

[0001] The utility model relates to the technical field of compaction devices, and particularly relates to an efficient compaction device for earthwork projects. Background Art

[0002] Earthwork backfilling is the process of filling the pre-dug space with earth and stone materials during construction to complete tasks such as ground leveling, foundation treatment, and construction waste treatment, usually using equipment such as compactors. After retrieval, the prior art (application number: CN202321888277.3) records "an earthwork backfilling vibration compaction device, which relates to the technical field of rammers, including a frame. One side of the upper end of the frame is fixedly installed with a chassis. An engine is fixedly installed on the frame on one side of the chassis. The output end of the engine is fixedly connected to the input end of the transmission mechanism inside the chassis. The lower end of the frame is movably installed with an installation roller. The rear end of the frame is fixedly installed with an operating rod. The outside of the installation roller is fixedly installed with a pressure roller. The outside of the pressure roller is fixedly installed with a plurality of outer lining plates. One side inside the outer lining plate is movably installed with fastening screws, and two limit rings are movably installed outside the fastening screws. The arrangement of a plurality of outer lining plates on the outside of the pressure roller can form a protective layer for the pressure roller, and the earthwork can be directly compacted through the structure composed of a plurality of outer lining plates. Moreover, the modular outer lining plates are conducive to the quick disassembly and assembly of the outer lining plates, improving the convenience of disassembly and assembly of the outer lining plates, so that there is no need to replace the whole as in the traditional pressure roller."

[0003] Although the existing earthwork backfilling vibration compaction device in the prior art has achieved the protection of the pressure roller and the replacement of the lining plate, there are still deficiencies: when the existing earthwork compaction device uses vibration to assist the pressure roller for compaction, the dry earthwork on the ground splashes dust, which affects the construction environment. Secondly, the compaction area of the existing compaction device cannot be adjusted during a single moving stroke, and it is not applicable to large earthwork backfilling projects, resulting in poor applicability of the compaction device. Content of the Utility Model

[0004] In order to overcome the defects existing in the prior art, the present utility model provides an efficient compaction device for earthwork projects to solve the problems that the existing earthwork compaction device is likely to cause dust impact on the construction environment and has poor applicability.

[0005] To achieve the above object, an efficient compaction device for earthwork projects is provided, including: a compactor, a dust suction component, and an auxiliary compaction roller. The bottom of the compactor is provided with its own compaction roller, and a first roller shaft is arranged inside the compaction roller. The auxiliary compaction roller is connected to the front and rear ends of the first roller shaft, and an installation plate is connected to the outer end of the auxiliary compaction roller. A second roller shaft is arranged inside the auxiliary compaction roller. The dust suction component is arranged at the bottom of the compactor and between its own compaction rollers. The dust suction component includes a dust suction head connected to the bottom shell of the compactor, and a protective net is arranged at the lower end of the dust suction head.

[0006] Further, a disassembly plate is arranged on the outer shell wall of the compactor, an installation cavity is opened inside the disassembly plate, and a conical cavity is opened at the lower end of the installation cavity.

[0008] Further, a plug block is arranged at one end of the second roller shaft connected to the first roller shaft, and the plug block is inserted into the plug hole in a matching manner.

[0009] Further, an outer shaft end with a cylindrical structure is arranged at the outer end of the second roller shaft, and the outer shaft end is rotatably connected to a shaft hole opened inside the installation plate. A long handle threaded rod is screwed inside the installation plate, and the long handle threaded rod is connected to a threaded hole opened on the outer wall of the compactor in a matching manner.

[0010] Further, the dust suction head is installed on the lower side of the conical cavity and surrounds the open bottom of the conical cavity. The upper end of the conical cavity is connected to a collection box through a connecting pipe.

[0011] Further, a blower is connected to one side of the collection box through a pipeline, a filter element is arranged on the side of the pipeline connected to the collection box, and both the collection box and the blower are installed in the installation cavity.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. During use, when the area of earthwork backfill is large, the compaction area in a single stroke of the compactor can be expanded. By using the plug hole opened at the outer end of the first roller shaft and the plug block arranged at one end of the second roller shaft, one end of the second roller shaft is connected to the first roller shaft, thereby achieving the effect of synchronous drive. Then, the outer shaft end at the outer end of the second roller shaft is rotatably connected to the shaft hole opened inside the installation plate, and at the same time, the installation plate is fixed on the outer shell of the compactor, so as to stably fix the outer end of the second roller shaft, and further keep the second roller shaft and the first roller shaft rolling in the same axial direction. When the compactor is working, an auxiliary compaction roller can be added on the basis of the original self-compaction roller, achieving the effect of expanding the compaction area, and thus improving the compaction efficiency;

[0014] 2. When the compactor is working, start the blower. Through the blower, passing through the collection box, connecting pipe and conical holes, a negative pressure suction effect is generated on the bottom suction head, so that during the vibration compaction process, the dust stirred up on the ground is timely sucked into the collection box, avoiding affecting the surrounding construction environment. Then, by removing the disassembly plate, the collection box can be taken out, facilitating the cleaning of the internal dust and filter element. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Referring to Figures 1 to 5 As shown, the present utility model provides an efficient compaction device for earthwork projects, including: a compactor 1, a dust suction assembly 2 and an auxiliary compaction roller 3. A self-compaction roller 12 is provided at the bottom of the compactor 1, and a first roller shaft 121 is provided inside the self-compaction roller 12. The auxiliary compaction roller 3 is connected to the front and rear ends of the first roller shaft 121, and a mounting plate 14 is connected to the outer end of the auxiliary compaction roller 3. And a second roller shaft 31 is provided inside the auxiliary compaction roller 3. The dust suction assembly 2 is arranged at the bottom of the compactor 1 and between the self-compaction rollers 12, and the dust suction assembly 2 includes a suction head 25 connected to the bottom shell of the compactor 1, and a protective net 26 is provided at the lower end of the suction head 25.

[0022] In this embodiment, the compactor 1, the dust suction assembly 2, and the auxiliary compaction roller 3 constitute the main structure of the high-efficiency compaction device for earthwork engineering involved in this application, which is used for compaction operations during earth backfilling.

[0023] Specifically, when not in use, the mounting plate 14 is hung on the L-shaped hanging plate welded to the outer shell of the compactor 1, and then a short bolt passes through the inside of the mounting plate 14 to press it tightly against the outside of the compactor 1.

[0024] Specifically, the outer structure of the auxiliary compaction roller 3 is the same as that of its own compaction roller 12. At the same time, the outer side is wrapped with a detachable connecting guard plate, and the outer diameter is also the same, so that it is convenient to be in a synchronous rolling state after being connected to each other.

[0025] As Figures 1 to 5 shown, the outer shell wall of the compactor 1 is provided with a disassembly plate 11, and an installation cavity 15 is opened on the inner side of the disassembly plate 11. A conical cavity 16 is opened at the lower end of the installation cavity 15. Both ends of the first roller shaft 121 extend out of the outer shell wall of the compactor 1, and a plug hole 122 is opened at the end of the first roller shaft 121. The cross section of the plug hole 122 is set as a rhombus structure. One end of the second roller shaft 31 connected to the first roller shaft 121 is provided with a plug block 32, and the plug block 32 is inserted into the plug hole 122 in a matching manner. The outer end of the second roller shaft 31 is provided with an outer shaft end 33 with a cylindrical structure, and the outer shaft end 33 is rotatably connected to the shaft hole 142 opened on the inner side of the mounting plate 14. At the same time, a long-handled threaded rod 141 is screwed inside the mounting plate 14, and the long-handled threaded rod 141 is connected to the threaded hole 13 opened on the outer wall of the compactor 1 in a matching manner.

[0026] Through the above technical solution, the connection between the first roller shaft 121 and the second roller shaft 31 is realized by using the rhombus-structured plug hole 122 and the plug block 32. Then, the second roller shaft 31 is squeezed and locked towards the compactor 1 side through the mounting plate 14 and the long-handled threaded rod 141, so as to achieve a stable support and positioning effect on the auxiliary compaction roller 3 connected to the outside of the second roller shaft 31. At the same time, the auxiliary compaction roller 3 can be flexibly disassembled when not in use.

[0027] As Figure 1 and Figure 3 shown, the dust suction head 25 is installed on the lower side of the conical cavity 16 and surrounds the bottom opening of the conical cavity 16. The upper end of the conical cavity 16 is connected to a collection box 22 through a connecting pipe 24. One side of the collection box 22 is connected to a fan 21 through a pipeline, and a filter element 23 is provided on the side where the pipeline is connected to the collection box 22. At the same time, both the hand collection box 22 and the fan 21 are installed in the installation cavity 15.

[0028] Specifically, the connection between the fan 21 and the collection box 22, and the connection between the collection box 22 and the connecting pipe 24 are set as detachable connections.

[0029] Through the above technical solution, when cleaning the collection box 22, the disassembly plate 11 can be opened, the collection box 22 can be taken out, and then the box cover can be opened to achieve the effect of cleaning dust and the filter element 23.

[0030] During use, when the area of earthwork backfilling is large, the compaction area in a single stroke of the compactor can be expanded. By using the insertion holes opened at the outer ends of the first roller shafts and the insertion blocks provided at one ends of the second roller shafts, one end of the second roller shaft is connected to the first roller shaft, thereby achieving the effect of synchronous drive. Then, the outer shaft end at the outer end of the second roller shaft is rotatably connected to the shaft hole opened on the inner side of the mounting plate. At the same time, the mounting plate is fixed to the housing of the compactor, so as to stably fix the outer end of the second roller shaft, and further keep the second roller shaft and the first roller shaft rolling in the same axial direction. When the compactor is working, an auxiliary compaction roller can be added on the basis of the original self-compaction roller of the compactor to achieve the effect of expanding the compaction area. When the compactor is working, the blower is started. Through the blower passing through the collection box, the connecting pipe and the conical hole, a negative pressure suction effect is generated on the dust suction head at the bottom, so that during the vibration compaction process, the dust stirred up on the ground is timely sucked into the collection box.

[0031] The high-efficiency compaction device for earthwork projects of the present utility model can effectively solve the problems that the existing earthwork compaction devices are prone to cause dust impact on the construction environment and have poor applicability. On the basis of the existing high-efficiency compaction device technology for earthwork projects, it has the effect of treating dust during the earthwork compaction process, and at the same time is convenient for expanding the compaction area in a single stroke of the compactor, improving the practicability of the device.
