Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a cement-stabilized crushed stone base continuous paving construction device. Background Art

[0002] Nowadays, in road construction, it is necessary to pave the foundation of the original road, compact it, and then build a cement road. For a long time, the cement stabilized gravel base of the cement road has been paved by layered machines, but the efficiency of layered machines is low, so people began to use continuous paving devices to continuously pave gravel and cement on the base.

[0003] The patent with announcement number CN218562018U discloses "a cement-stabilized gravel base two-layer joint paving construction device, which is intended to solve the technical problem that the gravel layer and the cement layer cannot be simultaneously joint paved under the existing technology. The two-layer joint paving construction device of the gravel base includes a tractor head. The two-layer joint paving construction device of the cement-stabilized gravel base only needs to drive the gravel in the gravel bucket to be spread on the road through the unloading component, and the gravel layer is compacted by the first pressure wheel. The setting of the control component facilitates the cement in the cement bucket to be discharged from the rectangular discharge pipe, and the cement surface is compacted by the second pressure wheel, thereby realizing the simultaneous joint paving of the gravel layer and the cement layer."

[0004] With regard to the above-mentioned related technologies, the inventors believe that the distribution of gravel from multiple spiral blades to the base layer is not uniform enough, which will form gravel piles that are high in the middle and low on both sides on the base layer. After the first pressure wheel spreads and compacts the gravel pile, it is easy to form grooves on the gravel layer, affecting the effect of subsequent cement paving. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a cement stabilized gravel base continuous paving construction device, and the specific technical scheme is as follows:

The bottom of the base frame is provided with a vibration mechanism for vibrating the gravel bucket, and the discharge end of the gravel bucket is provided with a paving mechanism for paving the gravel. The paving mechanism comprises a first telescopic part fixedly arranged on the outer wall of the bottom end of the gravel bucket, and a paving baffle plate fixedly arranged at the telescopic end of the first telescopic part, the bottom end of the paving baffle plate is slidably arranged in the discharge end of the gravel bucket, and a dredging mechanism is provided in the bottom end of the cement bucket.

[0007] By adopting the above technical solution, the crushed stones can be arranged neatly in the crushed stone bucket through the vibration of the vibration mechanism, and the extension and retraction of the first telescopic member can drive the flat material baffle plate to rise and fall, so that the crushed stones discharged from the crushed stone bucket can be evenly spread on the base layer under the vibration and the blocking of the bottom end of the flat material baffle plate.

[0008] Optionally, a towing head for connecting to a towing vehicle is fixedly provided on the top of one end of the base frame, and a first pressure wheel for pre-compacting the base layer is rotatably provided on the end of the base frame close to the towing head, and the compacting mechanism includes a second pressure wheel rotatably provided in the middle of the base frame for compacting the gravel after paving, and a third pressure wheel rotatably provided at one end of the base frame for compacting the cement after paving.

The second pressure wheel and other components can compact the laid gravel and cement.

[0010] Optionally, the vibration mechanism includes a vibration motor fixedly mounted on the outer bottom of the crushing bucket, and a plurality of springs fixedly arranged between the bottom of the crushing bucket and the top of the chassis.

[0011] By adopting the above technical solution, the vibration motor will drive the stone crushing bucket to vibrate after it is running, and the spring can reduce the influence of the vibration of the stone crushing bucket on the chassis.

[0013] By adopting the above technical solution, the dredging plate can dredge the bottom of the cement bucket after moving, ensuring smooth discharge of the cement bucket, and the through holes for cement to pass through can reduce the resistance when the dredging plate moves.

[0014] In summary, the present invention has at least one of the following beneficial effects:

[0015] 1. The vibration of the vibrating mechanism can make the crushed stones arranged neatly in the crushed stone bucket. The extension and retraction of the first telescopic member can drive the flat material baffle plate to rise and fall, so that the crushed stones discharged from the crushed stone bucket can be evenly laid on the base layer under the vibration and the blocking of the bottom end of the flat material baffle plate, which is convenient for the subsequent compaction of the crushed stones and the laying of cement.

The first pressing wheel 12, the second pressing wheel 13 and the third pressing wheel 14 can form three wheel bodies of the device to support the device.

[0026] Reference Figure 1-3 A vibration mechanism for vibrating the crushing bucket 2 is provided at the bottom of the chassis 1. The vibration mechanism includes a vibration motor 22 fixedly installed at the bottom of the outer side of the crushing bucket 2, and a plurality of springs 21 fixedly arranged between the bottom of the crushing bucket 2 and the top of the chassis 1. After the vibration motor 22 is running, it will drive the crushing bucket 2 to vibrate. The spring 21 is the spring used in the existing vibrating screen. The spring 21 can reduce the influence of the vibration of the crushing bucket 2 on the chassis 1. After the crushing bucket 2 vibrates, part of the vibration will be transmitted to the first pressure wheel 12, the cement bucket 3 and other components through the chassis 1. The first pressure wheel 12 and other wheel bodies cooperate with the vibration to improve the compaction effect, and the cement in the cement bucket 3 is easier to discharge under slight vibration.

[0027] Reference Figure 1-3 The discharging end of the crushing bucket 2 is provided with a paving mechanism for paving the crushed stones, and the paving mechanism includes a first telescopic member 23 fixedly arranged on the outer wall of the bottom end of the crushing bucket 2, and a paving baffle plate 24 fixedly arranged at the telescopic end of the first telescopic member 23, the bottom end of the paving baffle plate 24 is slidably arranged in the discharging end of the crushing bucket 2, and the paving baffle plate 24 is in an "L" shape. The first telescopic member 23 is an object with a telescopic effect such as an electric push rod, a cylinder and a hydraulic cylinder. After the first telescopic member 23 is extended and retracted, it will drive the paving baffle plate 24 to rise and fall, thereby controlling the opening and closing of the discharging end of the crushing bucket 2, and when the bottom end of the paving baffle plate 24 moves up, the crushed stones discharged from the crushing bucket 2 can be evenly spread on the base layer under the obstruction of the vibration and the bottom end of the paving baffle plate 24, and after the paving baffle plate 24 is raised and lowered, the shielding area of ​​the discharging end of the crushing bucket 2 can be controlled, thereby playing the effect of controlling the discharging amount and discharging speed of the crushed stones.

[0028] Reference Figure 2 and Figure 4 A second telescopic member 31 is fixedly provided on the outer wall of the bottom end of the cement bucket 3, and a discharge baffle 32 is fixedly provided on the telescopic end of the second telescopic member 31.

After the dredging plate 4 moves, it can dredge the bottom end of the cement bucket 3 to ensure smooth discharge of the cement bucket 3. The through holes 41 for cement to pass through can reduce the resistance of the dredging plate 4 when it moves, thereby reducing the load when the second telescopic member 31 drives the dredging plate 4 to move, and extending the service life of the second telescopic member 31.

[0030] The implementation principle of the cement stabilized gravel base continuous paving construction device of the utility model embodiment is:

[0031] When in use, people can connect the towing head 11 with an external traction vehicle. After the device is towed and moved as a whole, the first pressing wheel 12 will first perform preliminary compaction and flattening on the base layer. Then people can turn on the vibration motor 22 to drive the stone crushing bucket 2 to vibrate, and control the first telescopic member 23 to extend and retract to drive the flat material baffle plate 24 to move up and down. When the bottom end of the flat material baffle plate 24 moves up, the crushed stones discharged from the stone crushing bucket 2 can be evenly spread on the base layer under the vibration and the blocking of the bottom end of the flat material baffle plate 24.

[0032] Then, the laid gravel is compacted by the second pressing wheel 13, and then the second telescopic member 31 is controlled to be extended and retracted to drive the discharge baffle 32 and the dredging plate 4 to move laterally. When the second telescopic member 31 is extended, the discharge baffle 32 will move to the outside of the cement bucket 3, so that the bottom end of the cement bucket 3 is unblocked. At this time, the cement in the cement bucket 3 will be discharged through the bottom end, so that cement is laid on the surface of the gravel;

[0033] Then, the laid cement is compacted by the third pressing wheel 14, so that the base layer is stably laid with crushed stone and cement, thereby improving the construction efficiency.
