Description

Technical Field

[0001] The utility model relates to the technical field of paving machines, in particular to a paving mechanism and a paving machine. Background Art

[0002] The paver is an indispensable equipment in road construction, which is used to evenly spread asphalt mixture or other road materials on the roadbed. Among the key components of the paver, the spiral paver plays a vital role. It transports the material from the hopper to the paving surface through the rotating spiral blades, and performs preliminary distribution and leveling.

[0003] Traditional spiral pavers are usually composed of a series of spiral blades with fixed pitches, which rotate around a central axis to push the material forward. However, in actual use, these spiral blades often encounter the problem of material sticking. During the paving process, asphalt mixtures are prone to sticking to the spiral blades due to their viscosity and temperature characteristics, which not only affects the uniformity and efficiency of paving, but also causes accelerated wear of the spiral blades, increasing the maintenance cost and failure rate of the equipment.

[0004] Existing spiral pavers often lack effective self-cleaning mechanisms, making it difficult to remove stuck materials and requiring frequent manual intervention for cleaning. This not only reduces construction efficiency but also increases the workload of construction workers. At the same time, the sticking of materials may also lead to inconsistent thickness of the paving layer, affecting the flatness and service life of the road.

[0005] To this end, we propose a paving mechanism and a paving machine. Utility Model Content

[0006] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a paving mechanism and a paving machine.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a paving mechanism, including a driving frame, a spiral divider is arranged in the driving frame, a cleaning frame is fixedly installed on the side wall surface of the driving frame corresponding to the position above the spiral divider, a guide rod is axially fixedly installed in the cleaning frame, a cleaning rod which can slide axially along the guide rod is sleeved on the guide rod, the cleaning rod extends downward to the center of the spiral divider, a guide block is axially fixedly installed on the side wall surface of the guide rod, a cleaning mode groove and a reset mode groove which can accommodate the guide block are formed on the cleaning rod, the cleaning mode groove and the reset mode groove are staggered, and the staggering angle is the rotation angle of the cleaning rod when the cleaning rod is tilted to the edge of the spiral divider in a vertical state, and a reset spring is fixedly installed between the cleaning rod and the cleaning frame.

[0008] A scraper is detachably mounted at the position where the cleaning rod and the spiral distributor are in contact, and the scraper is a metal concave plate.

[0009] A limiting base is fixedly installed on the rear end face of the cleaning frame, a limiting groove is provided at the front end of the limiting base, a limiting block which can swing in the limiting groove is movably installed in the limiting groove, a moving magnet is fixedly installed on the front end face of the limiting block, a fixed magnet is fixedly installed at a position of the cleaning rod close to the moving magnet, and the moving magnet and the fixed magnet are magnetically connected.

[0010] The limiting groove is composed of a rectangular groove and circular grooves on both sides. A limiting rod is fixedly installed on the side wall surface of the limiting block. The limiting rod is a circular rod that can move on both sides of the limiting groove.

[0011] One end of the limiting block is located outside the limiting groove and the top end surface is an inclined surface.

[0012] A paving machine is also provided, comprising a paving machine frame and the above-mentioned paving mechanism.

[0013] Beneficial Effects

[0014] The utility model provides a paving mechanism and a paving machine, which have the following beneficial effects:

[0015] During operation, the spiral divider spreads the material to both sides, and the spread material will stick to the spiral divider. As the spiral divider rotates, the cleaning rod that remains in a vertical state slides forward along the guide rod under the push of the spiral divider. The cleaning mode slot and the guide block are used to limit the cleaning rod so that the cleaning rod remains vertical during the sliding process, allowing the scraper to scrape and clean the spiral divider. When the cleaning rod moves to the tail of the guide rod, the guide block no longer restricts the rotation of the cleaning rod. The cleaning rod is tilted under the push of the spiral divider and is simultaneously pulled by the reset spring. When the cleaning rod is tilted until the reset mode slot is aligned with the guide block, the cleaning rod is pulled back to its initial position by the reset spring, and then the moving magnet and the fixed magnet are attracted to each other. After the limit block moves up, the slot and the limit base are stuck, providing support for the upper end of the cleaning rod, so that the lower end of the cleaning rod cannot tilt outward, and can only move forward along the guide rod for a new round of scraping, repeating the cleaning of the spiral divider.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment: A paving mechanism, such as Figure 1-Figure 5As shown, a driving frame 1 is provided with a spiral distributor 2, and a cleaning frame 3 is fixedly installed on the side wall surface of the driving frame 1 at a position corresponding to the upper position of the spiral distributor 2. The main structure of the spiral distributor 2 is a spiral blade, which is an existing structure, and the purpose is to push the materials accumulated on the road surface to both sides. A guide rod 4 is axially fixedly installed in the cleaning frame 3, and a cleaning rod 5 that can slide axially along the guide rod 4 is sleeved on the guide rod 4. The cleaning rod 5 extends downward to the center of the spiral distributor 2. When the spiral distributor 2 rotates, it will contact the cleaning rod 5. As long as the cleaning rod 5 is kept vertical When the spiral divider 2 rotates, it will push the cleaning rod 5 to move horizontally along the guide rod 4. During the movement, the cleaning rod 5 will scrape off the residual materials on the spiral divider 2 to achieve the cleaning purpose. When the cleaning rod 5 slides along the guide rod 4 to the tail of the guide rod 4, the vertical state of the cleaning rod 5 is released. Under the push of the spiral divider 2, the cleaning rod 5 is tilted and moved to the outside of the edge of the spiral divider 2. At this time, the cleaning rod 5 is kept in the tilted state and returned to the initial position, and then kept in the vertical state again. Repeating this process can automatically clean the spiral divider 2.

[0027] Furthermore, in order to make the cleaning rod 5 maintain vertical stability and tilt stability during movement, a guide block 6 is axially fixedly installed on the side wall of the guide rod 4, and a cleaning mode groove 7 and a reset mode groove 8 that can accommodate the guide block 6 are opened on the cleaning rod 5. The cleaning mode groove 7 and the reset mode groove 8 are staggered and the staggered angle is the rotation angle when the cleaning rod 5 is tilted to the edge of the spiral divider 2 in the vertical state, which is forty-five degrees in the present embodiment. When cleaning the spiral divider 2, the cleaning rod 5 remains vertical, and the cleaning mode groove 7 slides on the guide block 6. When the cleaning rod 5 is reset, the reset mode groove 8 slides on the guide block 6. In other embodiments, the guide block 6, the cleaning mode groove 7 and the reset mode groove 8 can also be replaced by slide rails.

[0028] In order to enable the cleaning rod 5 to automatically reset, a reset spring 9 is fixedly installed between the cleaning rod 5 and the cleaning frame 3. The tension of the reset spring 9 makes the cleaning rod 5 always have a tendency to move to the initial position, so that after the cleaning rod 5 moves to the end of the guide rod 4, the reset mode groove 8 is aligned with the guide block 6 and then pulled back.

[0029] Furthermore, a scraper 10 is detachably mounted at the position where the cleaning rod 5 and the spiral distributor 2 are in contact. The scraper 10 is a metal concave plate that can scrape the spiral distributor 2 and is easy to replace.

[0030] Furthermore, in order to restore the cleaning rod 5 from the inclined state to the vertical state at the initial position and temporarily maintain the vertical state of the cleaning rod 5 before the spiral distributor 2 pushes the cleaning rod 5 into the guide block 6, a limiting base 11 is fixedly installed on the rear end surface of the cleaning frame 3, and a limiting groove 12 is provided at the front end of the limiting base 11. The limiting groove 12 is composed of a rectangular groove and circular grooves on both sides. A limiting block 13 that can swing in the limiting groove 12 is movably installed in the limiting groove 12. One end of the limiting block 13 is located outside the limiting groove 12 and the top end surface is an inclined surface. A limiting rod 17 is fixedly installed on the side wall surface of the limiting block 13. The limiting rod 17 is a circular rod that can move on both sides of the limiting groove 12. A moving magnet 15 is fixedly installed on the front end surface of the limiting block 13 , a fixed magnet 16 is fixedly installed at the position of the cleaning rod 5 near the moving magnet 15, and the moving magnet 15 and the fixed magnet 16 are magnetically connected. When the cleaning rod 5 moves to the front of the moving magnet 15, under the action of the magnetic force, the limit block 13 moves close to the fixed magnet 16, lifts itself, and slides along the inclined surface of the limit block 13 until the slot 14 is engaged with the limit base 11 to hold the limit block 13. At this time, the moving magnet 15 and the fixed magnet 16 are in contact, and the cleaning rod 5 remains in a vertical state. When the spiral distributor 2 rotates to push the cleaning rod 5 forward, the limit block 13 drops in front of the limit base 11, so that the cleaning rod 5 can only move forward along the guide rod 4 until the cleaning mode slot 7 slides on the guide block 6 and the fixed magnet 16 is separated from the moving magnet 15, completing the cleaning preparation.

[0031] A paving machine, such as Figure 1-2 As shown, it includes a paving frame 18 and the above-mentioned paving mechanism.

[0032] The working principle of the utility model is as follows: during the working process, the spiral distributor 2 spreads the material to both sides, and the spread material will adhere to the spiral distributor 2. As the spiral distributor 2 rotates, the cleaning rod 5, which is kept in a vertical state, slides forward along the guide rod 4 under the push of the spiral distributor 2. The cleaning mode groove 7 and the limit of the guide block 6 are used to keep the cleaning rod 5 vertical during the sliding process, so that the scraper 10 scrapes and cleans the spiral distributor 2. When the cleaning rod 5 moves to the tail of the guide rod 4, the guide block 6 no longer limits the cleaning rod 5. Rotate, the cleaning rod 5 is tilted under the push of the spiral distributor 2 and is simultaneously pulled by the reset spring 9. When the cleaning rod 5 is tilted until the reset mode slot 8 is aligned with the guide block 6, the cleaning rod 5 is pulled back to the initial position by the reset spring 9, and then the moving magnet 15 and the fixed magnet 16 are attracted to each other, and the limit block 13 moves up and the slot 14 is stuck with the limit base 11, providing support for the upper end of the cleaning rod 5, so that the lower end of the cleaning rod 5 cannot tilt outward, and can only move forward along the guide rod 4 for a new round of scraping, and repeatedly clean the spiral distributor 2.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
