[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0029] like Figures 1 to 3 As shown, a road compacting device described in an embodiment of the present application mainly includes a box body 1, a pressure roller 4 and a counterweight block 10.

[0030] The box body 1 can be made of metal material, for example, in a rectangular shape, with a cavity inside to place the counterweight 10. The box body 1 has a bottom plate and four side walls. The box body 1 can have a top plate or not.

[0031] A plurality of rollers 4 for compacting the road surface are rotatably mounted on the bottom of the housing 1 and arranged parallel to each other so that the rollers 4 have the same rotation direction. For example, a plurality of brackets 3 can be provided at the bottom of the housing 1, and bearings can be installed on these brackets 3. The ends of the rollers 4 are then assembled into the bearings to achieve connection between the rollers 4 and the housing 1.

[0032] A plurality of counterweights 10 are installed in the box body 1 to provide sufficient pressure to the pressure roller 4 .

[0033] In order to facilitate the removal and placement of the counterweight 10 in the box body 1, the embodiment of the present application also designs at least one side wall of the box body 1 as a baffle 2 with rotational freedom. The baffle 2 can be hinged around the edge of the box body 1 through hinges, pins and other mechanisms, and can then be rotated around the edge of the box body 1. It can also be converted between two states of being parallel to the bottom of the box body 1 or being set at an angle (the angle is preferably 90 degrees, that is, perpendicular to each other).

[0034] The embodiment of the present application can adjust the different compaction forces of the roller 4 on the road surface by increasing or decreasing the number of counterweights 10 in the box body 1. The counterweights 10 can be prefabricated concrete blocks or metal blocks with high density and good dimensional accuracy. In addition, the embodiment of the present application can also facilitate the removal and placement of the counterweights 10 by using a rotatable baffle 2. When the baffle 2 is rotated to be parallel to the bottom of the box body 1 (the baffle 2 is generally in a horizontal state at this time), if the counterweight 10 is to be placed in the box body 1, the counterweight 10 can be placed on the horizontal baffle 2 first, and then the counterweight 10 can be pushed into the box body 1; or when the counterweight 10 is to be taken out of the box body 1, the counterweight 10 can be pushed onto the horizontal baffle 2 first for manual or mechanical removal. After the counterweight 10 is removed and placed, the baffle 2 is rotated so that it is arranged at an angle to the bottom of the box 1 (for example, perpendicularly) and the baffle 2 is fixed so that it cannot rotate further, thereby limiting the counterweight 10 and preventing it from sliding out of the box 1. This also facilitates the transportation and use of the entire compacting device. The compacting device described in the embodiment of the present application has a simple structure, is easy to operate, can accurately control the compaction force, and is easy to transport and use.

[0035] like Figure 3~Figure 4 As shown, in the embodiment of the present application, a guide seat 11 may be further provided on a side of the baffle 2 near the counterweight 10, and the guide seat 11 may have a first sliding structure arranged with a sliding direction perpendicular to the rotation axis of the baffle 2. The first sliding structure may be, for example, a chute, and the counterweight 10 is placed in the chute of the horizontal baffle 2 and then pushed along the chute into the box body 1, thereby ensuring that the counterweight 10 is accurately and neatly placed in the box body 1.

[0036] In order to ensure that the counterweight 10 does not shake in the box 1, Figure 2 and Figure 3 As shown, a limiting support 9 can also be provided at the bottom and / or top of the box body 1. The limiting support 9 has a limiting structure provided in a taking and placing direction perpendicular to the rotation axis of the baffle 2, and the counterweight 10 is placed in the limiting structure of the limiting support 9. There can be one limiting support 9, or there can be multiple limiting supports 9, each of which is provided with a limiting structure. The limiting structure can be, for example, a groove. By placing the counterweight 10 in the box body 1 and embedding it in the groove, it can be ensured that the counterweight 10 will not shake in the box body 1, and it can also ensure that the counterweight 10 can be neatly arranged in the box body 1, which is convenient for controlling the center of gravity of the entire compacting device and for evenly distributing the gravity of the counterweight 10 to the pressing roller 4.

[0037] In addition, multiple rollers 12 can be arranged side by side in the first sliding structure of the guide seat 11, and the rotation axis of the roller 12 is arranged parallel to the rotation axis of the baffle 2, so that the friction of the counterweight block 10 is smaller and the movement is smoother when the counterweight block 10 moves in the first sliding structure of the guide seat 11, that is, it is easier and more effortless to transfer the counterweight block 10 between the baffle 2 and the box body 1.

[0038] As mentioned above, the counterweight 10 can be placed into or taken out of the box body 1 in a directional manner through the guide seat 11 on the baffle 2. Figure 3 As shown, a second sliding structure 13 can also be provided on the baffle 2, the sliding direction of which is parallel to the rotation axis of the baffle 2. The guide seat 11 is slidably connected to the second sliding structure 13, that is, the position of the first sliding structure of the guide seat 11 aligned with the inside of the box body 1 can be adjusted by sliding the guide seat 11. For example, after a counterweight 10 is placed in the box body 1, the guide seat 11 can be slid to the side by a distance of the width of the counterweight 10 to place the next counterweight 10 next to the previous counterweight 10 and close to it. The counterweights 10 placed in this way are arranged neatly and orderly, and are also easy to take out in an orderly manner.

[0039] The second sliding structure 13 can be a slide groove, in which a slide rod 14 is disposed. The guide base 11 is provided with a through hole and is slidably mounted on the slide rod 14. The slide rod 14 provides guidance and position limiting functions for the guide base 11, ensuring smooth sliding of the guide base 11 on the baffle 2 while preventing the guide base 11 from deflecting or misaligning during the sliding process.

[0040] A locking mechanism may also be provided between the sidewall of the housing 1 adjacent to the baffle 2 and the baffle 2. The locking mechanism can be used to lock the baffle 2 in position on the housing 1. For example, if the counterweight 10 needs to be removed or placed, the locking mechanism is operated to allow the baffle 2 to rotate freely. After the counterweight 10 is removed or placed, the locking mechanism is operated to lock the baffle 2 to the housing 1, preventing it from rotating.

[0041] The locking mechanism may include a slot 8 provided on the edge of the baffle 2 and a connector 7 provided on an adjacent side wall that can be inserted into and out of the slot 8. The connector 7 may be a spring latch, a bolt, or other mechanism or element that can achieve reciprocating insertion and withdrawal functions.

[0042] In order to prevent the pressure roller 4 from sticking to the dirt and other debris on the road surface and affecting the compaction effect, Figure 1 As shown, a scraper 5 can also be installed at the bottom of the box body 1 corresponding to the pressure roller 4. When the pressure roller 4 rolls, the dirt and other debris stuck on its surface will be scraped off by the scraper 5, thereby ensuring that the surface of the pressure roller 4 is always smooth.

[0043] The compacting device described in the embodiment of the present application can be resized as needed, and the specifications and number of the counterweights 10 can be adjusted adaptively. The compacting device can be manually pushed or driven by other power machinery to achieve road compaction. A handle 6 can be attached to the housing 1 to facilitate pushing or dragging.

[0044] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above preferred embodiments should not be construed as limiting the scope of the present invention. The scope of protection of the present invention shall be determined by the scope of the claims. Persons skilled in the art will appreciate that improvements and modifications may be made without departing from the spirit and scope of the present invention, and such improvements and modifications shall also be considered within the scope of protection of the present invention.
