A mixing rod 24 is fixedly connected to the bottom end of the output shaft of the mixing motor 23. A discharge pipe 25 communicating with the bottom of the mixing shell 3 is fixedly connected to the bottom of the mixing shell 3. The bottom end of the discharge pipe 25 passes through the mobile vehicle 1 and extends to its exterior. A solenoid valve is installed on the discharge pipe 25. By setting the mixing motor 23 and the mixing rod 24, it is convenient to mix and stir the asphalt to be filled. A through groove 26 communicating with the fixed shell 2 is opened on the top of the mobile vehicle 1.
[0023] Furthermore, a controller is fixedly connected to the top right side of the fixed shell 2, and fixed doors are movably connected to the left and right sides of the front of the fixed shell 2 via hinges. Opening the fixed doors facilitates operation of the internal structure of the fixed shell 2. A feeding cover is provided on the top left side of the mixing shell 3, and a heating block is installed on the top right side of the inner wall of the mixing shell 3.
[0024] It also includes a servo motor 6, which is mounted on the right side of the fixed housing 2. The servo motor 6 is a forward and reverse motor with a self-locking function. The left end of the output shaft of the servo motor 6 passes through the fixed housing 2 and extends into it. A threaded rod 7 is fixedly connected to the left end of the output shaft of the servo motor 6. A threaded block 8 is threadedly connected to the surface of the threaded rod 7. A recessed block 9 is fixedly connected to the bottom of the threaded block 8. An electric push rod 10 is fixedly connected to the bottom of the recessed block 9. A moving block 11 is fixedly connected to the bottom end of the electric push rod 10. The bottom of the moving block 11 is fixedly connected to the top of the adjusting block 4. The front and rear sides of the inner wall of the pressure roller bracket 5 are rotatably connected to the pressure roller 12 through bearings.
[0025] Furthermore, a positioning rod 21 is fixedly connected to the right side of the inner wall of the fixed shell 2. The left end of the positioning rod 21 passes through the threaded block 8 and extends to its outside, where it is fixedly connected to the right side of the stirring shell 3. By setting the positioning rod 21, the stability of the threaded block 8 when moving left and right is improved. A fixing rod 22 is fixedly connected to the right side of the top of the adjusting block 4. The top end of the fixing rod 22 passes through the concave block 9 and extends into its interior. By setting the fixing rod 22, the stability of the adjusting block 4 when moving up and down is improved.
[0026] Specifically, the servo motor 6, electric push rod 10, heating block, solenoid valve and stirring motor 23 are electrically connected to the controller.
[0027] By cooperating with the adjusting block 4, the pressure roller bracket 5, the servo motor 6, the threaded rod 7, the threaded block 8, the concave block 9, the electric push rod 10, the moving block 11 and the pressure roller 12, the filled asphalt can be automatically compacted by the pressure roller 12, avoiding the need for manual back-and-forth pushing and adjusting of the pressure roller 12 to compact the asphalt, thus improving work efficiency and reducing labor costs.
[0028] A slot 13 is provided at the top of the back of the pressure roller bracket 5. A plug 14 is fixedly connected to the bottom of the adjusting block 4 at the position corresponding to the slot 13. The bottom of the plug 14 penetrates the slot 13 and extends into it, contacting the inner wall of the slot 13. A fixing groove 15 is provided inside the adjusting block 4. An adjusting rod 16 is rotatably connected to the groove at the top of the inner wall of the fixing groove 15 via a bearing. The bottom end of the adjusting rod 16 penetrates the fixing groove 15 and extends outwards, where an anti-slip rotating block 17 is fixedly connected. The top of the anti-slip rotating block 17 rotatably contacts the bottom of the adjusting block 4. The anti-slip rotating block 17 and... The adjusting block 4 has a large frictional force to prevent the anti-slip rotating block 17 from rotating. The surface of the adjusting rod 16 is threaded with a movable block 18. The surface of the movable block 18 slides in contact with the inner wall of the fixed groove 15. A locking block 19 is fixedly connected to the left side of the bottom of the movable block 18. A slot 20 that matches the locking block 19 is opened at the bottom of the inner wall of the slot 13 and at the position corresponding to the locking block 19. The bottom of the locking block 19 passes through the fixed groove 15, the insert block 14, the slot 13 and the slot 20 from top to bottom and extends into the inside of the slot 20 to contact the inner wall of the slot 20.
[0029] Furthermore, a connecting rod 27 is fixedly connected to the top of the inner wall of the fixed groove 15. The bottom end of the connecting rod 27 passes through the movable block 18 and extends to its outside, where it is fixedly connected to the bottom of the inner wall of the fixed groove 15. By setting the connecting rod 27, the stability of the movable block 18 when it moves up and down is improved.
[0030] Specifically, open the fixed door, then rotate the anti-slip rotating block 17. The anti-slip rotating block 17 drives the adjusting rod 16 to rotate. The adjusting rod 16 drives the movable block 18 to move upward. The movable block 18 drives the locking block 19 to move upward, causing the locking block 19 and the locking groove 20 to separate. Then pull the pressure roller bracket 5 forward. The pressure roller bracket 5 drives the slot 13 to move forward, causing the slot 13 and the insertion block 14 to separate. This allows the pressure roller bracket 5 and the pressure roller 12 to be pulled out of the fixed shell 2, thus completing the disassembly.
[0031] The interplay of slot 13, insert block 14, fixing groove 15, adjusting rod 16, anti-slip rotating block 17, movable block 18, locking block 19 and locking groove 20 facilitates the disassembly and maintenance of pressure roller 12, making the disassembly and assembly process simple and convenient, and improving the flexibility of use.
[0032] When in use, open the feeding cover and put the asphalt into the inside of the mixing shell 3. Start the heating block and the mixing motor 23. The mixing motor 23 drives the mixing rod 24 to rotate through the output shaft to mix the asphalt and push the entire device to the position to be filled. Then open the solenoid valve on the discharge pipe 25 so that the asphalt is discharged into the pit through the discharge pipe 25. Then push the entire device so that the pressure roller 12 moves above the asphalt filling.
[0033] Start the electric push rod 10, which drives the pressure roller bracket 5 and the pressure roller 12 to move downwards, so that the pressure roller 12 passes through the through groove 26. After the pressure roller 12 and the asphalt make close contact, start the servo motor 6. The servo motor 6 drives the threaded rod 7 to rotate through the output shaft. The threaded rod 7 drives the threaded block 8 to move to the right first. The threaded block 8 drives the pressure roller 12 to move to the right through the concave block 9. The servo motor 6 drives the threaded rod 7 to rotate in the opposite direction, so that the pressure roller 12 can move to the left. Thus, the pressure roller 12 can move left and right repeatedly to compact the asphalt.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
