Description

Technical Field

[0001] This utility model belongs to the field of roadbed construction technology, and specifically relates to a crushed stone roadbed filling device. Background Technology

[0002] Subgrade construction and filling is a crucial process in road engineering, involving the layering and compaction of materials to form a subgrade structure that meets design requirements. Its core is to artificially fill the subgrade to achieve sufficient strength, stability, and uniformity in the natural foundation, providing reliable support for the pavement structure. Filling equipment is required during subgrade construction.

[0003] Existing filling devices typically involve placing processed crushed stone inside the device, then using a moving mechanism to move the device to a designated location and discharge the crushed stone through the discharge port to fill the road surface. However, in actual use, the following problems exist: because the crushed stone is in block form and is added in large quantities, it accumulates, which can easily cause blockages during the discharge process, causing trouble for the workers. To address this, we propose a crushed stone roadbed filling device. Utility Model Content

[0004] The purpose of this utility model is to provide a crushed stone roadbed filling device, which has the advantages of effectively preventing material blockage and improving the uniformity of material discharge.

[0009] The present invention is further configured such that a filter shell is bolted to the right side of the bottom of the inner cavity of the housing, a gas filter plate is bolted to the inner cavity of the filter shell, and a suction head is bolted to the top of the filter shell.

[0010] The above technical solution utilizes a gas filter plate to facilitate the filtration of absorbed dust, preventing dust from entering the inner cavity of the negative pressure fan and damaging its internal parts, thus improving the service life of the negative pressure fan.

[0011] The present invention is further configured such that a bearing is welded to the right side of the inner cavity of the box, and the right side of the rotating rod is rotatably connected to the inner cavity of the bearing.

An electric push rod 13 is bolted to the top of the left side of the inner cavity of the adjusting shell 9. A push plate 14 is bolted to the right side of the electric push rod 13, and a baffle 10 is welded to the left side of the push plate 14.

[0031] Furthermore, a bearing is welded to the right side of the inner cavity of the housing 1, and the right side of the rotating rod 12 is rotatably connected to the inner cavity of the bearing. Through the bearing, the stability of the rotation of the rotating rod 12 is improved.

[0032] Furthermore, a discharge port 11 is provided at the center of the bottom of the inner cavity of the box 1. The bottom of the discharge port 11 is in close contact with the surface of the baffle 10. Through the discharge port 11, crushed stone materials can be discharged.

[0033] Furthermore, slide rails 15 are welded to both ends of the inner cavity of the adjusting shell 9, and both ends of the push plate 14 are slidably connected to the inner cavity of the slide rails 15. The slide rails 15 improve the stability of the sliding of the push plate 14.

[0034] Furthermore, the bottom of the housing 1 is fixedly connected to the four sides of the shaft seat, and the bottom of the shaft seat is provided with casters, which allow the device to be moved.

[0035] Brief description of the operation: The electric push rod 13 pushes the push plate 14 to move, and the push plate 14 drives the baffle 10 to move, which can effectively control the discharge flow of the discharge port 11. The motor 2 drives the rotating rod 12 to rotate, which in turn drives the mixing blade 3 to rotate. The rotation of the mixing blade 3 mixes the crushed stone, and the crushed stone is discharged to the road surface through the discharge port 11.

[0036] Example 2:

[0037] refer to Figure 1 A crushed stone roadbed filling device includes a housing 5 welded to the right side of a box 1. A negative pressure fan 8 is bolted to the left side of the bottom of the inner cavity of the housing 5. An air intake pipe is bolted to the right side of the negative pressure fan 8, and an air outlet pipe is bolted to the bottom of the negative pressure fan 8. A filter shell 6 is bolted to the right side of the bottom of the inner cavity of the housing 5. A gas filter plate 7 is bolted to the inner cavity of the filter shell 6, and a suction head 4 is bolted to the top of the filter shell 6. The negative pressure fan 8 and the suction head 4 facilitate the absorption of dust generated by the crushed stone, preventing dust from floating and polluting the environment and threatening the respiratory health of workers. The gas filter plate 7 facilitates the filtration of the absorbed dust, preventing dust from entering the inner cavity of the negative pressure fan 8 and damaging its internal parts, thus improving the service life of the negative pressure fan 8.

[0039] Brief description of the usage process: First, the user puts the processed crushed stone into the inner cavity of the box 1. Next, the user holds the handle and, with the help of the casters, moves the device to the designated position. Then, the user starts the electric push rod 13 and motor 2 via the external controller. The electric push rod 13 pushes the push plate 14 to move, which in turn moves the baffle 10, effectively controlling the discharge flow rate of the outlet 11. The motor 2 drives the rotating rod 12 to rotate, which in turn drives the mixing blade 3 to rotate. The rotation of the mixing blade 3 stirs the crushed stone, allowing it to pass through... The material is discharged through outlet 11 to the road surface for filling work. During the mixing and tumbling of the crushed stone, dust is easily generated. The user starts the negative pressure fan 8 through the external controller. The negative pressure fan 8 can effectively generate suction by its own negative pressure. The suction is transmitted to the inner cavity of the filter shell 6 through the suction pipe. The filter shell 6 then transmits the suction to the suction head 4. The suction head 4 is used to absorb the floating dust. The dust enters the inner cavity of the filter shell 6 and passes through the gas filter plate 7 for filtration. The filtered gas is then discharged through the air outlet pipe on the surface of the negative pressure fan 8.
