Description

Technical Field

[0001] The present application relates to the field of road construction, and in particular to an asphalt leveling device. Background Art

[0002] Asphalt is a dark brown complex mixture of hydrocarbons of different molecular weights and their non-metallic derivatives. Asphalt mostly exists in the form of asphalt or tar, and the surface is black. It is mainly divided into three types: coal tar asphalt, petroleum asphalt and natural asphalt. It is mainly used in industries such as coatings, plastics, rubber, and road paving. When paving asphalt roads, some areas where large machines cannot be used, or when repairing some unsuccessfully paved roads, asphalt leveling devices are needed to pave the road;

[0003] Most of the asphalt leveling devices in the prior art can only level the newly laid asphalt pavement. Subsequently, another compacting equipment is required to repeatedly compact the pavement. This is not only very cumbersome to use but also wastes construction time and increases the labor intensity of the workers. Therefore, we urgently need to provide an asphalt leveling device. Utility Model Content

[0004] In order to solve the problem that only the newly laid asphalt pavement can be smoothed, and the road surface needs to be repeatedly compacted again using additional compaction equipment, which is not only very cumbersome to use and wastes construction time, but also increases the labor intensity of the workers, the present application provides an asphalt leveling device.

[0005] The asphalt leveling device provided in this application adopts the following technical solution:

[0006] An asphalt leveling device comprises a base, a bearing frame is fixedly mounted on the top of the base, and a compacting mechanism is arranged inside the bearing frame;

[0007] The compacting mechanism includes a servo motor, which is installed on the side of the supporting frame. The output end of the servo motor passes through the side of the supporting frame and is connected to a rotating shaft. The other end of the rotating shaft is rotatably connected to the inner surface of the supporting frame. Two eccentric wheels are fixedly installed in the middle of the rotating shaft. Fixed rods are fixedly installed on the bottom of the inner surfaces of the two eccentric wheels. A long rod is movably connected to the bottom of the fixed rod. Two connecting rods are symmetrically installed at both ends of the bottom of the long rod. A counterweight block is provided at the bottom of the long rod. A fixed seat is fixedly installed on the top of the counterweight block. The outer surfaces of the two connecting rods are rotatably connected to the inner surfaces of the fixed seats.

[0008] Preferably, a protective tube is fixedly mounted on the bottom of the inner surface of the carrier frame, the protective tube is arranged outside the counterweight block and guide grooves are evenly formed at both ends of the inner surface of the protective tube.

[0009] Preferably, sliding blocks are fixedly mounted on both side surfaces of the counterweight pressing block, and the outer surface of the sliding block is slidably connected to the inner surface of the guide groove.

[0010] Preferably, brake wheels are fixedly installed at the four corners of the bottom of the base, a material box is fixedly installed on the top of the base, a feed port is welded at the upper end of the material box, and a stirring motor is installed on the side of the material box.

[0011] Preferably, the output end of the stirring motor passes through the side of the material box and is connected to a rotating rod, a plurality of stirring rods are evenly and fixedly mounted on the outer surface of the rotating rod, and a material guide pipe is fixedly mounted on the bottom of the material box.

[0012] Preferably, a feed pump is fixedly mounted on one right end of the feed guide pipe, and a discharge pipe is mounted on the right output end of the feed pump.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. A compaction mechanism is set up, and a servo motor is used to drive the rotating shaft to rotate, so that the eccentric wheel rotates, thereby causing the long rod to reciprocate. The repeated movement of the long rod drives the counterweight block at the bottom to reciprocate up and down inside the protective tube, so that the counterweight block repeatedly presses the paved asphalt pavement, further improving the paving effect of the new asphalt on the road, saving the time cost of paving asphalt, ensuring the construction quality of the asphalt pavement, and facilitating use;

[0015] 2. By setting a stirring assembly inside the material box, the stirring motor drives the rotating rod to drive multiple stirring rods to rotate inside the material box, so as to facilitate the stable stirring of the asphalt material stored in the material box, prevent the asphalt from being placed in the material box for a long time and solidifying to affect the discharge effect, thereby enhancing the applicability of the device.
