Description

Technical Field

[0001] This utility model provides a roadbed and pavement compaction device, belonging to the field of road construction technology. Background Technology

[0002] Roadbed and pavement compaction equipment, also known as a soil compactor, is a type of road construction equipment. It falls under the category of road equipment in engineering machinery and is widely used in the filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. It can compact sandy, semi-cohesive, and cohesive soils, roadbed stabilized soils, and asphalt concrete pavement layers.

[0003] Existing roadbed and pavement compaction devices can basically meet normal usage needs. They generally include a roller, a frame that connects to the roller, and a compaction roller that is rotatably connected to the inner wall of the frame. In use, the frame is connected to the roller through the lugs. The movement of the roller moves the support frame, which in turn drives the compaction roller to rotate and compact the roadbed and pavement.

[0004] Based on the above research and existing technology, it has been found that during the compaction of roadbed and pavement, the roller inevitably raises dust, which can easily obstruct vision or be inhaled by workers. The working environment for roadbed and pavement compaction needs improvement. Therefore, this utility model provides a roadbed and pavement compaction device. Utility Model Content

[0005] The technical problem solved by this utility model is that too much dust is raised during the rolling process, which obstructs the view or is inhaled by workers, and the working environment needs to be improved.

[0006] To solve the technical problem, the technical solution provided by this utility model is as follows: a roadbed and pavement compaction device, including a support frame, with a compaction roller rotatably connected between the inner sidewalls of the support frame, and a dust suction and reduction component for sucking away and lowering dust raised during the compaction process on the support frame, the dust suction and reduction component including a C-shaped frame, a dust collection box and a water tank on the top of the C-shaped frame, a suction fan connected to the water tank on one side of the bottom of the dust collection box, a filter plate inclined and placed above the suction fan between the inner sidewalls of the dust collection box, and a dust collection hood connected to the top of the dust collection box on one side of the top of the support frame.

[0007] Furthermore, the C-shaped frame is fixed to the top of the support frame by bolts and is located outside the rolling roller, and the top of the dust collection box is provided with a dust collection pipe that is connected to the dust collection hood.

[0008] Furthermore, the exhaust port of the suction fan is provided with an air outlet pipe that passes through the top of the water tank, one end of the air outlet pipe is located in the lower part of the water tank, and the top of the water tank is provided with several air outlet holes located on one side of the air outlet pipe.

[0009] Furthermore, the support frame has a scraper plate placed on one side of the roller on one inner wall near the dust collection hood, and the minimum distance between the head end of the scraper plate and the side wall of the roller is 0.5-1.5mm.

[0010] Furthermore, the dust collection box is provided with a dust discharge pipe on the side wall away from the water tank, which is located at the top of the lower end of the filter plate, and the dust discharge pipe is provided with a dust discharge valve.

[0011] Furthermore, the bottom of the side wall of the water tank away from the dust collection box is provided with a connected drain pipe, and the drain pipe is equipped with a drain valve.

[0012] The beneficial effects of this utility model are:

[0013] By using the dust collection and dust suppression components and starting the suction fan, the dust raised during the compaction process can be sucked up and collected in the dust collection box. The suction fan then draws the air into the dust collection box, filters it through the filter screen, and sends it through the air outlet pipe to the water resource in the water tank. The humid air coming out of the water resource is discharged into the outside environment through the air outlet, thus suppressing the dust raised during the compaction process. This effectively removes and settles the dust raised during the compaction process, preventing excessive dust from obstructing vision or being inhaled by workers, and greatly improving the working environment for roadbed and pavement compaction.

It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0023] According to the appendix Figure 1 , 4 As shown in Figure 5: This utility model provides a roadbed and pavement compaction device, including a support frame 1. The support frame 1 is equipped with a dust suction and settling component 3 for sucking up and settling dust generated during compaction. The dust suction and settling component 3 includes a C-shaped frame 4 fixed to the top of the support frame 1 and positioned outside the compaction roller 2 by bolts. A dust collection box 5 and a water tank 6 are located on the top of the C-shaped frame 4. A suction fan 7 connected to the water tank 6 is located on one side of the bottom of the dust collection box 5. A filter plate 8, inclined and positioned above the suction fan 7, is located between the inner side walls of the dust collection box 5 to block dust and prevent a large amount of dust from being sucked into the suction fan. A dust suction hood 9 connected to the top of the dust collection box 5 is located on one side of the top of the support frame 1. A dust suction pipe 10 connected to the dust suction hood 9 is located on the top of the dust collection box 5. The blower 7 has an outlet pipe 11 that passes through the top of the water tank 6. One end of the outlet pipe 11 is located in the lower part of the water tank 6. The top of the water tank 6 has several outlet holes 12 located on one side of the outlet pipe 11. The top of the water tank 6 has a water inlet. When the water inlet is opened, water is injected into the water tank. The amount of water injected exceeds 2 / 3 of the capacity of the water tank 6. Specifically, when the blower 7 is started, the dust raised during the rolling process is sucked into the dust collection box 5 through the dust collection hood 9 and the dust collection pipe 10. The blower 7 then delivers the air that has been filtered by the filter plate 8 into the dust collection box 5 through the outlet pipe 11 to the water in the water tank 6. The humid air coming out of the water in the water tank 6 is discharged into the external environment through the outlet holes 12, which can effectively reduce the dust raised.

[0024] As per the instruction manual Figure 2 , 3As shown: A roller 2 is rotatably connected between the inner walls of the support frame 1. A scraper 13 is provided on one inner wall of the support frame 1 near the dust hood 9, which is placed on one side of the roller 2. The minimum distance between the head of the scraper 13 and the side wall of the roller 2 is 0.5-1.5mm. It is used to scrape off large pieces of roadbed and pavement soil attached to the roller 2. A hanging ear is provided on the side wall of the support frame 1 away from the dust hood 9. Specifically, the support frame 1 is connected to the road roller through the hanging ear. The movement of the road roller drives the support frame 1 to move, which in turn drives the roller 2 to rotate and compact the roadbed and pavement.

[0025] As per the instruction manual Figure 1 , 4 As shown: The dust collection box 5 is provided with a dust discharge pipe 14 on the side wall away from the water tank 6, which is located at the top of the lower end of the filter plate 8. The dust discharge pipe 14 is provided with a dust discharge valve. The bottom of the side wall of the water tank 6 away from the dust collection box 5 is provided with a connected drain pipe 15. The drain pipe 15 is provided with a drain valve. Specifically, when the dust discharge pipe 14 is opened, the dust that is stuck on the top of the filter plate 8 slides down and is discharged from the dust discharge pipe 14. When the drain valve is opened, the water mixed with dust in the water tank 6 is discharged from the drain pipe 15.

[0026] The principle of this utility model

[0027] During use, the movement of the road roller causes the roller 2 to rotate and compact the roadbed. Since dust is inevitably raised during the compaction process, the dust suction component 3 and the suction fan 7 are activated. The dust raised during the compaction process is sucked into the dust collection box 5 through the dust suction hood 9 and the dust suction pipe 10. A large amount of dust is retained on the top of the filter plate 8. The dust raised can be sucked away and collected in the dust collection box 5. The suction fan 7 delivers the air sucked into the dust collection box 5 and filtered by the filter plate 8 through the air outlet pipe 11 to the water resource in the water tank 6. The humid air coming out of the water resource in the water tank 6 is discharged into the external environment through the air outlet 12. The water and dust combine to form larger particles and fall with gravity, so as to suppress the dust raised. In this way, the dust raised during the compaction process can be effectively sucked away and settled, so as to prevent too much dust from obstructing the vision or being inhaled by the workers. The working environment of the roadbed and road surface compaction is greatly improved.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
