Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically to a road compaction device. Background Technology

[0002] In modern road construction, road compaction is a crucial step. It directly affects the service life and load-bearing capacity of the road, as well as driving safety and comfort. During road construction, soil compaction is usually required to give the road better overall stability, resist the effects of external factors such as rainwater erosion and temperature changes, and reduce the occurrence of road defects. It plays a significant role in improving the density, load-bearing capacity, stability, and durability of the road.

[0003] However, during road compaction, numerous hard lumps and particles remain on the road surface. During compaction, these lumps are not easily compressed into the soil, creating numerous voids between them. This results in an uneven road surface, reducing road density and compaction effectiveness, and causing significant difficulties in the road compaction process. Therefore, this applicant proposes a road compaction device to address these problems. Utility Model Content

[0004] The purpose of this invention is to provide a road compaction device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a road compaction device, comprising a compaction mechanism, a pre-compaction mechanism assembled at the front end of the compaction mechanism, and a cleaning mechanism assembled at the rear end of the pre-compaction mechanism;

[0006] The compaction mechanism includes a frame, and two symmetrically distributed axle frames are fixedly installed at the bottom of the frame, with a steel wheel rotatably mounted between the two axle frames;

[0007] The pre-compression mechanism includes two shaft arms fixedly installed at the front end of the vehicle frame, a rotating roller rotatably installed between the two shaft arms, a rolling cylinder fixedly installed on the outer side of the rotating roller, a plurality of uniformly distributed through holes on the surface of the rolling cylinder, and a plurality of crushing cones extending into the through holes fixedly installed on the surface of the rotating roller.

[0008] Preferably, an engine is fixedly mounted on the top of the frame, and the output shaft of the engine is connected to the steel wheel via a belt drive.

[0009] Preferably, a protective cover covering the outside of the engine is fixedly installed on the top of the frame, and a storage box is fixedly installed on the top of the frame and on one side of the protective cover.

[0010] Preferably, a handrail is fixedly installed at the rear end of the vehicle frame, and the rotating roller and the rolling cylinder are fixedly installed together by a fixing block.

[0011] Preferably, a support frame is fixedly installed between the shaft arms, and a counterweight box is fixedly installed on the top of the support frame.

[0012] Preferably, the cleaning mechanism includes two fixed brackets fixedly installed at the rear end of the shaft arm, a fixed plate fixedly installed between the two fixed brackets, and a cleaning brush corresponding to the roller cylinder fixedly installed at the front end of the fixed plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this road compaction device for construction,

[0014] Equipped with a pre-compaction mechanism, the rolling roller allows soil particles to enter the through-holes. The crushing cone then breaks up these particles, facilitating the crushing of harder soil clods on the road surface. This results in a more even distribution of soil particles, making them easier to compact into the soil, reducing gaps between particles, and increasing road density. This effectively improves the compaction effect of the steel rollers on the road surface, reducing the occurrence of raised, broken soil particles and greatly facilitating road compaction work.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a road compaction device, including a compaction mechanism 1, a pre-compression mechanism 2 assembled at the front end of the compaction mechanism 1, and a cleaning mechanism 3 assembled at the rear end of the pre-compression mechanism 2. The compaction mechanism 1 includes a frame 101, with two symmetrically distributed axle frames 102 fixedly installed at the bottom of the frame 101. A steel wheel 103 is rotatably installed between the two axle frames 102. The pre-compression mechanism 2 includes two axle arms 201 fixedly installed at the front end of the frame 101. A rotating roller 202 is rotatably installed between the two axle arms 201. A rolling cylinder 204 is fixedly installed on the outer side of the rotating roller 202. The surface of the rolling cylinder 204 has multiple evenly distributed through holes 206. Multiple crushing cones 205 extending into the through holes 206 are fixedly installed on the surface of the rotating roller 202.

[0023] Based on the above structural design, this road compaction device consists of a compaction mechanism 1, a pre-compaction mechanism 2, and a cleaning mechanism 3. The pre-compaction mechanism 2 performs pre-compaction on the road surface, breaking up harder soil particles and ensuring even distribution of soil clods. The compaction mechanism 1 facilitates compaction of the pre-compacted surface, improving the compaction effect. The cleaning mechanism 3 removes soil clods adhering to the surface of the pre-compaction mechanism 2, maintaining a good pre-compaction effect. Specifically, during the construction process, by... The device is moved to the road surface that needs to be compacted. The movement of the frame 101 enables the roller 204 to pre-compact the road surface, allowing the broken soil particles on the road surface to enter the through hole 206. The roller 202 limits the crushing cone 205, enabling the crushing cone 205 to crush the broken soil particles. This facilitates the crushing of harder broken soil particles, loosens the soil clods on the road surface, and makes it easier for the particles on the road surface to be pressed into the soil. Through the rolling action of the steel wheel 103, the pre-compacted road surface is compacted, effectively improving the compaction effect.

[0024] Furthermore, an engine 105 is fixedly mounted on the top of the frame 101, and the output shaft of the engine 105 is connected to the steel wheel 103 via a belt 108. The engine 105 is a diesel engine, which provides power to the steel wheel 103, and the belt 108 can be used to drive the steel wheel 103 to rotate, which can facilitate the movement of this device.

[0025] Furthermore, a protective cover 104, which covers the outside of the engine 105, is fixedly installed on the top of the frame 101, and a storage box 107 is fixedly installed on the top of the frame 101 and on one side of the protective cover 104. The protective cover 104 protects the engine 105 from collisions with external objects, while the storage box 107 provides convenient storage for tools needed for maintenance and other items required for work, making them easily accessible to staff.

[0026] Furthermore, a handrail 106 is fixedly installed at the rear end of the frame 101, and the rotating roller 202 and the rolling cylinder 204 are fixedly installed together by a fixing block 203. The handrail 106 provides a convenient grip and facilitates the movement and operation of the device.

[0027] Furthermore, a support frame 208 is fixedly installed between the axle arms 201, and a counterweight box 207 is fixedly installed on the top of the support frame 208. The support frame 208 can support the counterweight box 207, and the counterweight box 207 can be used to conveniently place counterweight blocks, which can increase the weight of the preloading mechanism 2, so that the rolling cylinder 204 can easily crush the soil on the road surface.

[0028] Furthermore, the cleaning mechanism 3 includes two fixed brackets 301 fixedly installed at the rear end of the shaft arm 201, and a fixed plate 302 fixedly installed between the two fixed brackets 301. A cleaning brush 303 corresponding to the roller cylinder 204 is fixedly installed at the front end of the fixed plate 302. The fixed brackets 301 support the fixed plate 302, allowing the cleaning brush 303 to contact the surface of the roller cylinder 204. During the rotation of the roller cylinder 204, the cleaning brush 303 can clean the soil adhering to the surface of the roller cylinder 204, avoiding blockage of the through hole 206.
