[0024] like Figures 1 to 4As shown, a compacting mechanism of an asphalt paver comprises a fixed plate 1, and two electric push rods 2 are fixedly connected to the top of the fixed plate 1. When the electric push rod 2 is started, the output shaft of the electric push rod 2 is extended and retracted to drive the connecting frame 3 to rise or fall, and then when the connecting frame 3 is lowered, the compacting block 12 is driven downward, and the compacting block 12 falls and compacts the asphalt. A connecting frame 3 is fixedly connected to one side of the output shaft of the two electric push rods 2, and two fixed rods 4 are fixedly connected to one side of the connecting frame 3. A moving block 5 is slidably connected to the outer surfaces of the two fixed rods 4, and a connecting plate 6 is fixedly connected between the two moving blocks 5 on the same side, and a plug-in column 7 is fixedly connected to one side of the two connecting plates 6, and a moving plate 8 is fixedly connected to one side of the two plug-in columns 7, and two moving plates 8 are provided with two connecting plates on one side. Through holes, the outer surfaces of the two movable plates 8 are plugged with a fixed frame 9, the movement of several movable blocks 5 will drive the plug-in column 7 to move, and the movement of the plug-in column 7 will make the movable plate 8 move inside the fixed frame 9. During the movement of the two movable blocks 8, the damping fluid continuously flows from the through hole opened on one side of the movable block 8 to the other side. During the flow of the damping fluid, the friction between the inner wall of the through hole and the oil and the internal friction between the oil molecules form a damping force on the vibration, thereby hindering the movement of the movable plate 5 and completing the buffering of the device. One side of the two fixed frames 9 is fixedly connected to one side of the connecting frame 3 respectively, and the bottom of several movable blocks 5 are rotatably connected to a connecting rod 10, one side of several connecting rods 10 is rotatably connected to a positioning plate 11, and the bottom of the positioning plate 11 is fixedly connected to a shock block 12.

[0025] A first fixing hole is provided on both sides of the connection frame 3 , and the interiors of a plurality of the first fixing holes are respectively fixedly connected to the interiors of the corresponding first fixing holes. Two sliding grooves are provided on the top of the connection frame 3 .

[0026] The tops of several moving blocks 5 are fixedly connected with a plug-in block, and the outer surfaces of several plug-in blocks are slidably connected to the inside of corresponding slide grooves. The plug-in blocks are set to slide on the outer surfaces of the slide grooves, so that the moving blocks 5 will not rotate when moving and the moving blocks 5 will be more stable when moving, thereby increasing the stability of the device.

[0027] A spring 401 is sleeved on the outer surface of the two fixed rods 4, and one side of several springs 401 is fixedly connected to one side of the connecting frame 3, and the other side of several springs 401 is fixedly connected to one side of the corresponding moving block 5. Through the set springs 401, the force applied to the moving block 5 is buffered when the moving block 5 moves, and the moving block 5 will not cause damage to one side of the connecting frame 3 due to moving too fast.

[0028] A slot is formed inside each of the two fixing frames 9 . The shape and size of the two slots match the shape and size of the moving plate 8 . The insides of the two slots are respectively plugged into the outer surfaces of the corresponding moving plates 8 .

[0029] One side of the two slots is provided with a second fixing hole, and the insides of the two second fixing holes are respectively plugged into the outer surfaces of the corresponding plug-in posts 7 .

[0030] A plurality of connecting rods 10 are symmetrically arranged.

[0032] The above-mentioned electrical components are all existing technology products. They are selected, installed and the circuit debugging work is completed by technical personnel in this field according to the needs of use to ensure that all electrical appliances can work normally. The components are all universal standard parts or components known to technical personnel in this field. Their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods. The applicant does not make specific restrictions here.

[0033] A vibrating mechanism for an asphalt paver, the working principle of which is as follows:

[0034] 1) The worker of the asphalt paver compaction mechanism installs the fixed plate 1 in the asphalt paver, connects the electric push rod 2 to the external power supply, and starts the electric push rod 2 during operation. The output shaft of the electric push rod 2 is extended and retracted to drive the connecting frame 3 to rise or fall, and then when the connecting frame 3 falls, it drives the compaction block 12 downward, and the compaction block 12 falls and compacts the asphalt;

[0035] 2) When compacting the asphalt, the compacting block 12 applies a certain pressure to the ground, and the ground transfers part of the force to the compacting block 12. The compacting block 12 is subjected to the force and drives the positioning plate 11 to move. The movement of the positioning plate 11 drives the connecting rod 10 to move. The connecting rod 10 drives several moving blocks 5 to move on the outer surface of the fixed rod 4. The movement of several moving blocks 5 drives the plug-in column 7 to move. The movement of the plug-in column 7 causes the moving plate 8 to move inside the fixed frame 9. During the movement of the two moving blocks 8, the damping fluid continuously flows from the through hole opened on one side of the moving block 8 to the other side. During the flow of the damping fluid, the friction between the inner wall of the through hole and the oil and the internal friction between the oil molecules form a damping force on the vibration, thereby hindering the movement of the moving plate 5 and completing the buffering of the device.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] The worker of the asphalt paver compaction mechanism installs the fixed plate 1 in the asphalt paver and connects the electric push rod 2 to the external power supply. When working, the electric push rod 2 is used to make the compaction block 12 fall and compact the asphalt. Through the action of the positioning plate 11, the connecting rod 10, the moving block 5, the plug-in column 7, the moving plate 8 and the damping liquid inside the fixed frame 9, the damping liquid continuously flows from the through hole opened on one side of the moving block 8 to the other side during the movement of the two moving blocks 8. During the flow of the damping liquid, the friction between the inner wall of the through hole and the oil and the internal friction between the oil molecules form a damping force on the vibration, thereby hindering the movement of the moving plate 5, which can improve the buffering effect of the device, and further reduce the shock of the paver, solving the problem that the paver will be subjected to bumps and vibrations when the compaction mechanism is compacted, which is easy to cause damage to the parts of the paver itself, thereby reducing the service life.
