Description

Technical Field

[0001] The utility model belongs to the technical field of roadbed construction equipment, and in particular relates to a roadbed filling and rolling device. Background Art

[0002] When constructing the roadbed, it is often necessary to use ash soil for filling. After filling, the ash soil roadbed needs to be compacted by a rolling device to increase the density and strength of the roadbed. During the rolling construction of the roadbed, the compaction roller moves on the top of the roadbed for rolling. During the rolling process, the ash soil will adhere to the outside of the compaction roller, affecting the flatness of the rolling.

[0003] In the prior art, for example, a Chinese utility model patent document with authorization announcement number CN221276251U discloses a roadbed compaction device for solidified expansive soil, which scrapes away dust adhering to the compaction roller during the rolling process to avoid affecting the flatness of the rolling; in the non-rolling state, the scraper is separated from the compaction roller by manually adjusting the screw rod to avoid wear and extend the life of the scraper. The adjustment process takes a lot of time, which affects the use efficiency.

[0004] Therefore, it is necessary to design a roadbed filling and rolling device that can quickly control the contact or separation of the scraper and the compaction roller to improve the utilization efficiency to solve the current technical problems. Summary of the invention

[0005] In view of the deficiencies existing in the prior art, the utility model provides a roadbed filling and rolling device which can quickly control the contact or separation between a scraper and a compaction roller to improve the use efficiency.

[0006] The technical solution of the utility model is: a roadbed filling and rolling device, comprising a support frame, a compaction roller is rotatably arranged inside the support frame, a scraper parallel to the axis of the compaction roller is arranged on the inner side of the support frame, a scraper support strip is detachably fixedly arranged on one side of the scraper, swing arms are fixedly arranged at both ends of the scraper support strip, a support arm corresponding to the swing arm is fixedly arranged on the support frame, the upper end of the swing arm is rotatably connected to the support arm, and a driving mechanism is arranged on the support frame; the driving mechanism is used to drive the swing arm to reciprocate so that the scraper and the compaction roller abut or separate.

[0007] The driving mechanism comprises a supporting seat rotatably arranged on the top of the supporting frame, a lead screw is rotatably arranged on the supporting seat, a driving motor for driving the lead screw to rotate is arranged on the end of the lead screw away from the supporting seat, and the lead screw is threadedly connected with the driving seat; a supporting rod is arranged between the two swing arms, and the driving seat is rotatably sleeved on the outside of the supporting rod.

[0008] Two guide rods parallel to the lead screw are symmetrically arranged on the support base. One end of each guide rod away from the support base is fixedly provided with an end plate. The drive motor is arranged on the end plate, and the drive seat is slidably sleeved outside the guide rod.

[0009] The drive motor is a servo motor or a stepper motor.

[0010] Supports are rotatably arranged at both ends of the support base, and the supports are fixedly arranged on the top of the support frame.

[0011] A scraper positioning groove matching the scraper is formed on one side of the scraper support bar, and the scraper is detachably and fixedly arranged inside the scraper positioning groove.

[0012] The scraper is detachably and fixedly arranged inside the scraper positioning groove through scraper fixing bolts.

[0013] Advantages of the present utility model:

[0014] (1) During the rolling construction of the present utility model, the scraper is automatically driven by the drive mechanism to abut against the compaction roller. During the rolling process, the scraper can scrape off the ash and soil adhered to the compaction roller, avoiding affecting the flatness of rolling.

[0015] (2) In the non-rolling state, the drive mechanism automatically and quickly replaces manual labor to drive the scraper to separate from the compaction roller, which can avoid mutual wear between the compaction roller and the scraper in the non-rolling state and extend the service life of the scraper.

[0016] (3) When the scraper is worn, the drive mechanism can drive the scraper to move, so that the scraper remains in an abutting state with the compaction roller, thereby ensuring the cleaning effect on the compaction roller.

[0017] (4) The scraper is detachably fixed on one side of the scraper support bar. When the scraper is worn to a certain extent, the scraper can be removed and replaced. Description of the drawings

A scraper 4 parallel to the axis of the compaction roller 2 is arranged inside the support frame 1. A scraper support bar 3 is detachably and fixedly arranged on one side of the scraper 4. Swing arms 5 are fixedly arranged at both ends of the scraper support bar 3. Support arms 6 corresponding to the swing arms 5 are fixedly arranged on the support frame 1. The upper ends of the swing arms 5 are rotatably connected to the support arms 6. A driving mechanism 7 is arranged on the support frame 1; the driving mechanism 7 is used to drive the swing arms 5 to reciprocate so that the scraper 4 abuts against or separates from the compaction roller 2; in this embodiment, during compaction construction, the driving mechanism 7 automatically drives the scraper 4 to abut against the compaction roller 2. During the compaction process, the scraper 4 can scrape off the ash and soil adhered to the compaction roller 2, avoiding affecting the flatness of compaction; in the non-compaction state, the driving mechanism 7 automatically drives the scraper 4 to separate from the compaction roller 2, which can avoid mutual wear between the compaction roller 2 and the scraper 4 in the non-compaction state and extend the service life of the scraper 4; when the scraper 4 is worn, the driving mechanism 7 can drive the scraper 4 to move so that the scraper 4 remains in an abutting state with the compaction roller 2, thereby ensuring the cleaning effect on the compaction roller 2; the scraper 4 is detachably and fixedly arranged on one side of the scraper support bar 3.

A driving seat 72 is threadedly connected to the lead screw 76. A support rod 8 is arranged between the two swing arms 5. The driving seat 72 is rotatably sleeved on the outside of the support rod 8. The driving motor 74 can drive the lead screw 76 to rotate. When the lead screw 76 rotates, the thread structure between it and the driving seat 72 can drive the driving seat 92 to move along the lead screw 76. When the driving seat 92 moves, it drives the swing arm 5 to swing through the support rod 8. When the swing arm 5 swings, the scraper support bar 3 at its end drives the scraper 4 to approach or move away from the compaction roller 2.

[0026] In some embodiments, two guide rods 75 parallel to the lead screw 76 are symmetrically arranged on the support base 71. One end of the guide rod 75 away from the support base 71 is fixedly provided with an end plate 73. The driving motor 74 is arranged on the end plate 73.
