Description

Technical Field

[0001] This utility model relates to the field of compaction machine technology, specifically to a noise-reducing compaction machine. Background Technology

[0002] Soil compactors are generally used to compact soil, increasing its load-bearing capacity. They are frequently used in road and building construction. A soil compactor primarily uses a drive mechanism to move a compaction head, which then hammers the ground to compact the soil. Existing soil compactors are mainly hand-held vibratory compactors, which use a vibrator to drive the compaction head to vibrate, thus achieving compaction. However, existing hand-held vibratory compactors lack a buffer function, generate significant noise during vibration, and are prone to damage. Furthermore, they require manual movement, making operation laborious and inconvenient. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned problems and provide a noise-reducing tamping machine. This tamping machine can play a buffering role during the tamping process, which greatly reduces noise and provides good protection for the tamping machine. In addition, the tamping machine has an automatic movement function, which greatly improves the convenience of use, saves time and labor, and thus improves work efficiency.

[0004] The objective of this utility model is achieved through the following technical solution: A noise-reducing compaction machine includes a frame, wheels mounted on the lower end of the frame, a driving mechanism for rotating the wheels, a guide frame mounted on the frame, a sliding frame vertically slidably mounted on the guide frame, a compaction head mounted below the frame, a connecting frame between the sliding frame and the compaction head, and a compaction driving mechanism for driving the sliding frame to move up and down. The upper end of the connecting frame is vertically slidably connected to the lower end of the sliding frame, and the lower end of the connecting frame is fixedly connected to the top of the compaction head. A spring is provided between the sliding frame and the connecting frame, with the upper end of the spring acting on the sliding frame and the lower end of the spring acting on the connecting frame. An adjusting nut is provided at the upper end of the connecting frame for adjusting the working length of the spring.

[0005] The working principle of the above-mentioned noise reduction compactor is: During operation, the walking drive mechanism drives the wheels to rotate, thereby enabling the compactor to move automatically. When the compactor moves to the work site, the compaction drive mechanism can drive the sliding frame to move up and down, thereby driving the connecting frame to move, and in turn driving the compaction head to hammer the ground, compacting the ground. Due to differences in ground elevation and soil hardness, the compaction head can easily cause the entire compactor to vibrate during the hammering process, and also generate significant vibration and noise on the ground. In the compactor of this utility model, during the hammering process, the sliding frame and the connecting frame will move relative to each other, and under the action of the spring, they will play a great buffering role. The compaction head does not make hard contact with the ground, thereby reducing the generation of vibration, greatly reducing noise, and providing a good protection for the compactor. By adjusting the nut, the working length of the spring can also be adjusted, thereby achieving the adjustment of the spring stiffness and realizing different compaction effects, improving the flexibility of operation. When the working length of the spring decreases, the spring is compressed, the spring stiffness increases, and the stroke decreases; when the working length of the spring increases, the spring is released and extended, the spring stiffness decreases, and the stroke increases.

[0006] In a preferred embodiment of this utility model, the sliding frame includes a sliding plate, a guide post disposed at the lower end of the sliding plate, and a limiting plate disposed on the guide post. The sliding plate is slidably connected to the guide frame. The connecting frame includes a connecting post, a connecting plate disposed at the upper end of the connecting post, and sliding posts disposed at both ends of the connecting plate. The lower end of the connecting post is connected to the compaction head. The two sliding posts are slidably connected to both ends of the limiting plate. Two springs and two adjusting nuts are used; the two springs are respectively sleeved on the two sliding posts, and the two adjusting nuts are respectively disposed at the upper ends of the two sliding posts. The upper end of the spring acts on the limiting plate, and the lower end of the spring acts on the connecting plate. In the above structure, by setting two springs, the buffering effect can be further improved, making the noise reduction effect more significant. Setting two sliding posts can improve the stability of the sliding connection between the sliding frame and the connecting frame. By turning the adjusting nuts, the distance between the limiting plate and the connecting plate can be adjusted, thereby adjusting the working length of the spring.

[0007] Preferably, the limiting plate is disposed in the middle of the guide post, and the connecting plate is provided with a guide hole, which extends through the connecting plate to the connecting post; the lower end of the guide post is slidably engaged with the guide hole. By setting the above structure, the guide post can be slidably connected with the guide hole, which further improves the stability of the sliding connection between the sliding frame and the connecting frame, and also makes the structure very compact.

[0008] Preferably, the lower end of the frame is provided with a dustproof and soundproof cover, and the tamping head is located inside the dustproof and soundproof cover. By setting up the dustproof and soundproof cover, the dust generated by the tamping head during the hammering process can be blocked, and it can also play a certain role in sound insulation, making the noise reduction effect more significant.

[0009] Preferably, the vehicle frame is equipped with a lifting drive mechanism for driving the dustproof and soundproof cover to move up and down. The lifting drive mechanism includes a mounting frame and an electric push rod. The electric push rod is mounted on the vehicle frame, the upper end of the mounting frame is connected to the electric push rod, and the top of the dustproof and soundproof cover is connected to the lower end of the mounting frame. In the above structure, when the compactor needs to move, the electric push rod drives the mounting frame to move upward, thereby moving the dustproof and soundproof cover upward, so that the dustproof and soundproof cover is away from the ground, facilitating the movement of the compactor. When the ground needs to be compacted, the electric push rod drives the mounting frame to move downward, thereby moving the dustproof and soundproof cover downward, so that the bottom of the dustproof and soundproof cover contacts the ground, achieving a good dustproof and soundproof effect.

[0010] Preferably, the mounting bracket includes a mounting plate and mounting rods disposed at both ends of the mounting plate, the dustproof and soundproof cover is disposed on the mounting rods, and the electric push rod is connected to the mounting plate. This structure provides excellent installation for the dustproof and soundproof cover.

[0011] Preferably, the lower end of the mounting rod passes through the top of the dustproof and soundproof cover, and the dustproof and soundproof cover is slidably connected to the mounting rod. A limiting block is provided at the lower end of the mounting rod, and a buffer spring is sleeved on the mounting rod. The upper end of the buffer spring acts on the mounting plate, and the lower end of the buffer spring acts on the top of the dustproof and soundproof cover. With this structure, when the dustproof and soundproof cover contacts the ground, the dustproof and soundproof cover and the mounting rod can slide relative to each other, compressing the buffer spring. This provides excellent cushioning for the dustproof and soundproof cover, preventing hard contact with the ground and damage. Simultaneously, the elasticity of the buffer spring also helps the dustproof and soundproof cover press firmly against the ground, achieving a good sealing effect and further improving the dustproof and noise reduction effect. When the dustproof and soundproof cover moves upward, the limiting block prevents it from detaching from the mounting rod, ensuring a good installation.

[0012] Preferably, the system also includes a water spraying mechanism, which comprises a water tank mounted on the vehicle frame for storing water, an annular spray nozzle located inside the dust cover for spraying water, a water pump mounted on the water tank, and a water supply pipe connecting the water pump and the annular spray nozzle. In this structure, the inlet of the water pump is connected to the water tank, and the outlet is connected to the water supply pipe. During the compaction process, the water pump delivers water from the water tank to the annular spray nozzle, which then atomizes and sprays the water, effectively reducing dust.

[0013] Preferably, the compaction drive mechanism includes a compaction drive motor, a compaction reduction gearbox, a drive disc, and an eccentric column. The compaction reduction gearbox is mounted on the vehicle frame. The main shaft of the compaction drive motor is connected to the input end of the compaction reduction gearbox. The drive disc is connected to the output end of the compaction reduction gearbox. The eccentric column is eccentrically positioned on the drive disc. The sliding plate has a horizontal groove, and the eccentric column is engaged with the horizontal groove. Driven by the compaction drive motor and transmitted by the compaction reduction gearbox, the drive disc rotates, which in turn drives the eccentric column to rotate around the center of the drive disc, thereby causing the sliding plate to move up and down.

[0014] Preferably, the walking drive mechanism includes a walking drive motor, a walking reduction gearbox, and a chain drive mechanism. The walking reduction gearbox is mounted on the frame, and the main shaft of the walking drive motor is connected to the input end of the walking reduction gearbox. One end of the chain drive mechanism is connected to the output end of the walking reduction gearbox, and the other end of the chain drive mechanism is connected to the wheel. In this structure, the walking drive motor provides power, and the wheels rotate under the drive of the walking reduction gearbox and the chain drive mechanism, thereby enabling the compactor to move.

[0015] Compared with the prior art, the present invention has the following advantages: 1. In the noise reduction tamping machine of this utility model, during the process of hammering the ground, the sliding frame and the connecting frame will move relative to each other, and under the action of the spring, they play a great buffering role. The tamping head does not make hard contact with the ground, thereby reducing the generation of vibration, greatly reducing noise, and playing a good protective role for the tamping machine.

[0016] 2. The noise-reducing compactor of this utility model can also adjust the working length of the spring by adjusting the nut, thereby realizing the adjustment of the spring stiffness and achieving different compaction effects, thus improving the flexibility of the work.

[0017] 3. The noise-reducing compactor in this utility model drives the wheels to rotate through the walking drive mechanism, thereby realizing the automatic movement of the compactor, which greatly improves the convenience of use, saves time and labor, and thus improves work efficiency.

[0027] To enable those skilled in the art to fully understand the technical solution of this utility model, the present utility model will be further described below in conjunction with the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0028] Example 1 See Figures 1-6 This embodiment discloses a noise-reducing compaction machine, including a frame 1, wheels 2 disposed at the lower end of the frame 1, a walking drive mechanism 3 for driving the wheels 2 to rotate, a guide frame 4 disposed on the frame 1, a sliding frame 5 vertically slidably disposed on the guide frame 4, a compaction head 6 disposed below the frame 1, a connecting frame 7 disposed between the sliding frame 5 and the compaction head 6, and a compaction drive mechanism 8 for driving the sliding frame 5 to move up and down back and forth; the upper end of the connecting frame 7 is vertically slidably connected to the lower end of the sliding frame 5, and the lower end of the connecting frame 7 is fixedly connected to the top of the compaction head 6; wherein, a spring 9 is provided between the sliding frame 5 and the connecting frame 7, the upper end of the spring 9 acts on the sliding frame 5, and the lower end of the spring 9 acts on the connecting frame 7; the upper end of the connecting frame 7 is provided with an adjusting nut 10 for adjusting the working length of the spring 9.

[0029] See Figures 1-6The sliding frame 5 includes a sliding plate 501, a guide post 502 disposed at the lower end of the sliding plate 501, and a limiting plate 503 disposed on the guide post 502. The sliding plate 501 is slidably connected to the guide frame 4. The connecting frame 7 includes a connecting post 701, a connecting plate 702 disposed at the upper end of the connecting post 701, and sliding posts 703 respectively disposed at both ends of the connecting plate 702. The lower end of the connecting post 701 is connected to the compaction head 6. The two sliding posts 703 are slidably connected to both ends of the limiting plate 503 respectively. There are two springs 9 and two adjusting nuts 10. The two springs 9 are respectively sleeved on the two sliding posts 703, and the two adjusting nuts 10 are respectively disposed at the upper ends of the two sliding posts 703. The upper end of the spring 9 acts on the limiting plate 503, and the lower end of the spring 9 acts on the connecting plate 702. In the above structure, by setting two springs 9, the buffering effect can be further improved, making the noise reduction effect more significant. Setting two sliding columns 703 can improve the stability of the sliding connection between the sliding frame 5 and the connecting frame 7. By turning the adjusting nut 10, the distance between the limiting plate 503 and the connecting plate 702 can be adjusted, thereby adjusting the working length of the spring 9.

[0030] See Figures 1-6 A shim is provided between the adjusting nut 10 and the limiting plate 503. By setting the shim, the stability of the adjusting nut 10 can be improved and the adjusting nut 10 can be prevented from loosening during operation.

[0031] See Figures 1-6 The sliding frame 5 is an integral structure, and the adjusting nut 10 is located above the limiting plate 503.

[0032] See Figures 1-6 The limiting plate 503 has sliding holes at both ends, and two sliding columns 703 are slidably connected to the sliding holes respectively. The sliding frame 5 has a symmetrical structure, and the connecting frame 7 also has a symmetrical structure, the purpose of which is to ensure the stability of the connection between the sliding frame 5 and the connecting frame 7. The guide frame 4 can be a gantry frame.

[0033] See Figures 1-6 The limiting plate 503 is disposed in the middle of the guide post 502. The connecting plate 702 is provided with a guide hole 704, which extends through the connecting plate 702 to the connecting post 701. The lower end of the guide post 502 is slidably engaged with the guide hole 704. By setting the above structure, the guide post 502 can be slidably connected with the guide hole 704, which further improves the stability of the sliding connection between the sliding frame 5 and the connecting frame 7, and also makes the structure very compact.

[0034] See Figures 1-6The lower end of the frame 1 is provided with a dustproof and soundproof cover 11, and the tamping head 6 is located inside the dustproof and soundproof cover 11. By setting the dustproof and soundproof cover 11, the dust generated by the tamping head 6 during the hammering process can be blocked, and at the same time, it can also play a certain role in sound insulation, making the noise reduction effect more significant.

[0035] See Figures 1-9 The vehicle frame 1 is equipped with a lifting drive mechanism for driving the dustproof and soundproof cover 11 to move up and down. The lifting drive mechanism includes a mounting frame 12 and an electric push rod 13. The electric push rod 13 is mounted on the vehicle frame 1, the upper end of the mounting frame 12 is connected to the electric push rod 13, and the top of the dustproof and soundproof cover 11 is connected to the lower end of the mounting frame 12. In the above structure, when the compactor needs to move, the electric push rod 13 drives the mounting frame 12 to move upward, thereby moving the dustproof and soundproof cover 11 upward, so that the dustproof and soundproof cover 11 is away from the ground, making it convenient for the compactor to move. When the ground needs to be compacted, the electric push rod 13 drives the mounting frame 12 to move downward, thereby moving the dustproof and soundproof cover 11 downward, so that the bottom of the dustproof and soundproof cover 11 contacts the ground, achieving a good dustproof and soundproof effect.

[0036] See Figures 1-9 The mounting bracket 12 includes a mounting plate 1201 and mounting rods 1202 disposed at both ends of the mounting plate 1201. The dustproof and soundproof cover 11 is disposed on the mounting rods 1202, and the electric push rod 13 is connected to the mounting plate 1201. Using the above structure, the dustproof and soundproof cover 11 can be effectively installed.

[0037] See Figures 1-9 The lower end of the mounting rod 1202 passes through the top of the dustproof and soundproof cover 11. The dustproof and soundproof cover 11 is slidably connected to the mounting rod 1202. The lower end of the mounting rod 1202 is provided with a limiting block 1203. A buffer spring 14 is sleeved on the mounting rod 1202. The upper end of the buffer spring 14 acts on the mounting plate 1201, and the lower end of the buffer spring 14 acts on the top of the dustproof and soundproof cover 11. By setting the above structure, when the dustproof and soundproof cover 11 comes into contact with the ground, the dustproof and soundproof cover 11 and the mounting rod 1202 can slide relative to each other, and the buffer spring 14 is compressed. The purpose is to provide a good buffer for the dustproof and soundproof cover 11, prevent the dustproof and soundproof cover 11 from making hard contact with the ground and damaging the dustproof and soundproof cover 11. At the same time, the elasticity of the buffer spring 14 can also make the dustproof and soundproof cover 11 press firmly against the ground, achieving a good sealing effect and further improving the dustproof and noise reduction effect. When the dustproof and soundproof cover 11 moves upward, due to the action of the limiting block 1203, the dustproof and soundproof cover 11 will not detach from the mounting rod 1202, achieving a good installation effect.

[0038] See Figures 1-9A guide rod 15 is provided between the dustproof and soundproof cover 11 and the vehicle frame 1. The guide rod 15 is slidably connected to the vehicle frame 1, and the lower end of the dustproof and soundproof cover 11 is connected to the guide rod 15. The mounting plate 1201 is slidably connected to the guide rod 15. By setting the guide rod 15, the stability of the vertical movement of the dustproof and soundproof cover 11 and the mounting frame 12 can be improved.

[0039] See Figures 1-9 The noise-reducing compactor in this embodiment also includes a water spraying mechanism 6. The water spraying mechanism 6 includes a water storage tank 1601 mounted on the frame 1 for storing water, an annular spray pipe 1602 located inside the dust cover for spraying water, a water pump 1603 mounted on the water storage tank 1601, and a water supply pipe 1604 connecting the water pump 1603 and the annular spray pipe 1602. In this structure, the inlet of the water pump 1603 is connected to the water storage tank 1601, and the outlet is connected to the water supply pipe 1604. During compaction, the water pump 1603 delivers water from the water storage tank 1601 to the annular spray pipe 1602, and then atomizes and sprays it out from the annular spray pipe 1602, which can reduce dust.

[0040] See Figures 1-9 The annular nozzle 1602 is provided with multiple nozzles, which are evenly distributed along the circumference to improve the dust removal effect.

[0041] See Figures 1-6 The compaction drive mechanism 8 includes a compaction drive motor 801, a compaction reduction gearbox 802, a drive disc 803, and an eccentric column 804. The compaction reduction gearbox 802 is mounted on the frame 1. The main shaft of the compaction drive motor 801 is connected to the input end of the compaction reduction gearbox 802. The drive disc 803 is connected to the output end of the compaction reduction gearbox 802. The eccentric column 804 is eccentrically positioned on the drive disc 803. The sliding plate 501 has a horizontal sliding groove 5011, and the eccentric column 804 is engaged with the horizontal sliding groove 5011. Driven by the compaction drive motor 801 and transmitted by the compaction reduction gearbox 802, the drive disc 803 is rotated, which in turn drives the eccentric column 804 to rotate around the center of the drive disc 803, thereby causing the sliding plate 501 to move up and down.

[0042] See Figures 1-6The walking drive mechanism 3 includes a walking drive motor 301, a walking reduction gearbox 302, and a chain drive mechanism 303. The walking reduction gearbox 302 is mounted on the frame 1, and the main shaft of the walking drive motor 301 is connected to the input end of the walking reduction gearbox 302. One end of the chain drive mechanism 303 is connected to the output end of the walking reduction gearbox 302, and the other end of the chain drive mechanism 303 is connected to the wheel 2. In the above structure, the walking drive motor 301 provides power, and under the drive of the walking reduction gearbox 302 and the chain drive mechanism 303, the wheel 2 rotates, thereby realizing the movement of the compactor.

[0043] See Figures 1-6 The frame 1 is equipped with a front axle and a rear axle, and wheels 2 are provided at both ends of the front axle and the rear axle. The chain drive mechanism 303 consists of a driving sprocket, a driven sprocket, and a chain, with the driven sprocket mounted on the rear axle. By driving the rear axle to rotate, the wheels 2 are driven to rotate, thus achieving movement.

[0044] See Figures 1-6 The working principle of the above-mentioned noise reduction compactor is as follows: During operation, the walking drive mechanism 3 drives the wheels 2 to rotate, thereby enabling the compactor to move automatically. When the compactor moves to the work site, the compaction drive mechanism 8 can drive the sliding frame 5 to move up and down, thereby driving the connecting frame 7 to move, and then driving the compaction head 6 to hammer the ground, compacting the ground. Due to differences in ground elevation and soil hardness, the compaction head 6 is prone to vibration during the hammering process, which also generates significant vibration and noise to the ground. In the compactor of this utility model, during the hammering process, the sliding frame 5 and the connecting frame 7 will move in opposite directions. The spring 9 acts as a great buffer for the movement of the compactor, preventing the compaction head 6 from making hard contact with the ground, thus reducing vibration and noise, and providing excellent protection for the compactor. The working length of the spring 9 can be adjusted by adjusting the nut 10, thereby adjusting its stiffness to achieve different compaction effects and improving operational flexibility. When the working length of the spring 9 decreases, it is compressed, increasing its stiffness and reducing its stroke; conversely, when the working length increases, it is released and extended, decreasing its stiffness and increasing its stroke.

[0045] Example 2 The other structures in this embodiment are the same as in embodiment 1, except that the number of adjusting nuts 10 is four; each sliding column 703 is provided with two adjusting nuts 10. The double nut setting can improve the stability of the adjusting nuts 10 and prevent the adjusting nuts 10 from loosening during operation.

[0046] The above are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
