Description
Technical Field
[0001] This utility model relates to the field of road construction processing equipment, and in particular to a roadbed compactor that prevents building materials from sticking together and improves flatness. Background Technology
[0002] A road compactor is a widely used piece of machinery in the construction industry. Its core function and main purpose is to compact the ground or roadbed to ensure that the ground meets the standards of firmness and flatness. This equipment uses pressure or vibration to force soil particles to clump together tightly, significantly reducing voids in the soil, thereby improving the bearing capacity and stability of the ground. The use of road compactors is crucial for ensuring the quality of infrastructure such as roads, parking lots, and airport runways, as they can effectively reduce ground settlement and deformation, extending the service life of the infrastructure.
[0003] Among the numerous mechanical equipment used in construction, road compactors come in a wide variety, each with its own design and function. Telescopic and eccentric types are two common examples. Telescopic compactors, due to their design flexibility, can be adjusted to meet different construction needs, adapting to various ground conditions and construction environments. This type of compactor provides a more uniform and effective compaction effect, contributing to improved construction quality and efficiency. Eccentric compactors, on the other hand, have a fixed compaction effect and cannot be adjusted to different construction needs, which limits their application range to some extent. Compared to telescopic compactors, eccentric compactors are less effective at achieving uniform ground compaction, which may affect the final construction quality. Therefore, construction teams need to select the appropriate type of road compactor based on specific project requirements and ground conditions. Utility Model Content

[0032] Reference Figures 1 to 6 In one embodiment of this utility model, a roadbed compactor for preventing building materials from sticking together and improving flatness includes:
[0033] Substrate 100 serves as the structural basis;
[0034] The work box 200 is disposed at one end of the substrate 100 along its length.
[0035] A support plate 300 is disposed at the other end of the substrate 100 along its length.
[0036] A rotary driver 400 is installed in the work box 200. The output end of the rotary driver 400 is connected to a first rotating rod 410 that extends along the length of the substrate 100 and is connected to the support plate 300. A plurality of first eccentric hammers 420 are provided corresponding to the first rotating rod 410. The fixed position of the first eccentric hammers 420 on the first rotating rod 410 is adjustable.
[0037] Two follower rotators 500 are installed on the working box 200 and located on both sides of the rotary driver 400. The output end of the follower rotator 500 is connected to a second rotating rod 510 that extends along the length of the base plate 100 and is connected to the support plate 300. A plurality of second eccentric hammers 520 are provided corresponding to the second rotating rod 510. The fixed position of the second eccentric hammers 520 on the second rotating rod 510 is adjustable.
[0038] Two transmission gear sections 600 are disposed on both sides of the rotary driver 400 and transmit the rotation of the rotary driver 400 to the two follower rotators 500.
[0039] In existing technologies, the compaction effect of eccentric compactors is fixed, so it cannot be adjusted according to different construction needs, which limits its application range to some extent.
[0040] This utility model provides a roadbed compactor that prevents building materials from sticking together and improves flatness. The base plate 100 serves as the structural foundation; the base plate 100 is generally plate-shaped, but not limited to a strictly plate structure. The working box 200 is located at one end of the base plate 100 along its length, providing a spatial foundation for subsequent components.
[0041] The support plate 300 is disposed at the other end of the substrate 100 along its length. The support plate 300 and the substrate 100 can be an integral structure or a connection and fixing structure.
[0042] A rotary actuator 400 is mounted on the work box 200. The output end of the rotary actuator 400 is connected to a first rotating rod 410 extending along the length of the base plate 100 and connected to the support plate 300. The operation of the rotary actuator 400 drives the first rotating rod 410 to rotate. A plurality of first eccentric hammers 420 are provided corresponding to the first rotating rod 410, and the fixed positions of the first eccentric hammers 420 on the first rotating rod 410 are adjustable. When the first eccentric hammers 420 rotate with the first rotating rod 410, a vibration effect is generated. After adjusting the first eccentric hammers 420 to a suitable position as needed, they are fixed, thereby generating a vibration effect at a specific location.
[0043] Two follower rotators 500 are mounted on the work box 200 and located on both sides of the rotary driver 400. The output end of each follower rotator 500 is connected to a second rotating rod 510 extending along the length of the base plate 100 and connected to the support plate 300. A plurality of second eccentric hammers 520 are provided corresponding to the second rotating rod 510, and the fixed positions of the second eccentric hammers 520 on the second rotating rod 510 are adjustable. When the second eccentric hammers 520 rotate with the second rotating rod 510, they generate a vibration effect. After adjusting the second eccentric hammers 520 to a suitable position as needed, they are fixed, thereby generating a vibration effect at a specific location.
[0044] Two transmission gear sections 600 are disposed on both sides of the rotary driver 400 and transmit the rotation of the rotary driver 400 to the two follower rotary units 500. The transmission gear sections 600 form a gear transmission structure with the rotary driver 400, so that the follower rotary units 500 do not need to be equipped with a separate matching motor.
[0045] In summary, the rotary actuator 400 provides rotary drive, the first eccentric hammer 420 on the first rotating rod 410 provides compaction effect, and the intensity of compaction effect at different positions can be adjusted by adjusting the position of multiple first eccentric hammers 420; the power of the rotary actuator 400 is distributed to the width direction of the roadbed compactor by the follower rotator 500, and the intensity of compaction effect at different positions can also be adjusted by adjusting the position of multiple first eccentric hammers 420 on the follower rotator 500.
[0046] Reference Figure 3 In one embodiment, the roadbed compactor further includes an auxiliary gear section 700, which, together with the transmission gear section 600, clamps the follower rotator 500.
[0047] In this embodiment, considering that the follower rotator 500 only forms a gear transmission with the transmission gear section 600, and that the follower rotator 500 is equipped with a second eccentric hammer 520, the rotational stability of the follower rotator 500 is subject to a significant challenge. Adding an auxiliary gear section 700 makes the rotation of the follower rotator 500 more stable without interfering with its rotation.
[0048] In one embodiment, the auxiliary gear section 700 has the same shape as the transmission gear section 600.
[0049] In this embodiment, the shapes of the two are made consistent, thereby reducing the difficulty of processing, installation and maintenance.
[0050] In one embodiment, the first eccentric hammer 420 is pinned to the first rotating rod 410, and the second eccentric hammer 520 is pinned to the second rotating rod 510.
[0051] In this embodiment, the pin connection method has the characteristics of simplicity and stability. Taking the first eccentric hammer 420 as an example, fixing holes are set at multiple positions on the first rotating rod 410, the first eccentric hammer 420 is placed at a specific fixing hole position, and then a fixed connection is achieved by using a pin.
[0052] In one embodiment, the first rotating rod 410 has first fixing holes at both ends and the middle part along its length, and the second rotating rod 510 has second fixing holes at both ends and the middle part along its length. The first eccentric hammer 420 is connected to the first fixing hole by a pin, and the second eccentric hammer 520 is connected to the second fixing hole by a pin.
[0053] In this embodiment, taking the first rotating rod 410 as an example, a suggested setting position for the first fixing hole is given, so that the first eccentric hammer 420 can be fixed at different positions on the first rotating rod 410. It should be noted that multiple first fixing holes can be set at the same position on the first rotating rod 410, so that multiple first eccentric hammers 420 can be installed at the same position. For example, three first eccentric hammers 420 can be set at one end of the length direction of the first rotating rod 410 at the same time, so as to form a stronger vibration effect at that position.
[0054] In one embodiment, the first eccentric hammer 420 is slidably disposed along the length of the first rotating rod 410 and is circumferentially restricted and fixed; the second eccentric hammer 520 is slidably disposed along the length of the second rotating rod 510 and is circumferentially restricted and fixed.
[0055] In this embodiment, the first eccentric hammer 420 slides to a suitable position along the length of the first rotating rod 410 and then is fixed, so that the first eccentric hammer 420 can be conveniently adjusted in position and can generate a vibration effect at the designed position; the interaction between the second eccentric hammer 520 and the second rotating rod 510 is analogous.
[0056] In one embodiment, the first eccentric hammer 420 is fixed upward around the first rotating rod 410; the second eccentric hammer 520 is fixed upward around the second rotating rod 510.
[0057] In this embodiment, although the first eccentric hammer 420 and the second eccentric hammer 520 are fixed by pins, there is no relative rotation between the first eccentric hammer 420 and the first rotating rod 410, and there is no relative rotation between the second eccentric hammer 520 and the second rotating rod 510. This reduces the fastening force requirement of the pins and also reduces the possibility of malfunctions of the first eccentric hammer 420 and the second eccentric hammer 520.
[0058] In one embodiment, a cover plate is provided corresponding to the substrate 100, and when the cover plate is installed on the substrate 100, it covers the rotary driver 400 and the follower rotator 500.
[0059] In this embodiment, the cover plate conceals the rotary driver 400 and the follower rotator 500 during operation, thereby reducing the risk of accidents and protecting the internal working environment. The connection between the cover plate and the base plate 100 can be made using bolts or similar methods.
[0060] In one embodiment, the support plate 300 supports one end of the first rotating rod 410 away from the working box 200 and the other end of the second rotating rod 510 away from the working box 200 via a bearing structure.
[0061] In this embodiment, the bearing structure improves the fixing effect of the first rotating rod 410 and the second rotating rod 510 without interfering with normal rotation.
[0062] In one embodiment, the transmission gear section 600 is a helical gear.
[0063] In this embodiment, a more stable rotational transmission is achieved by using helical gears. The rotary driver 400 and the follower rotator 500 also need to be equipped with helical gear structures at the positions of the corresponding transmission gear parts 600 to complete the gear transmission matching.
[0064] In summary, the roadbed compactor provided by this utility model, which avoids the adhesion of building materials and improves flatness, uses a rotary driver 400 to provide rotational drive, and a first eccentric hammer 420 on a first rotating rod 410 to provide compaction effect. By adjusting the position of multiple first eccentric hammers 420, the intensity of the compaction effect at different positions can be adjusted. The power of the rotary driver 400 is distributed to the width direction of the roadbed compactor by a follower rotator 500, and the intensity of the compaction effect at different positions can also be adjusted by adjusting the position of multiple first eccentric hammers 420 on the follower rotator 500.
[0065] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
