[0002] Asphalt concrete is a mixture made by artificially selecting mineral materials with a certain graded composition (crushed stone or crushed gravel, stone chips or sand, mineral powder, etc.) and a certain proportion of road asphalt materials, and mixing them under strictly controlled conditions. When actually producing asphalt concrete, an agitator is required to complete the heating and mixing of the asphalt mixture. In actual use, it has the advantages of simple operation, stable structure and good use effect.

[0003] The prior art discloses an asphalt concrete mixing instrument with announcement number: CN218263322U. This utility model drives the transmission shaft through a motor, which in turn drives the stirring blades to stir the asphalt mixture inside the mixing barrel. However, the rotating stirring blades cannot ensure that all the asphalt mixture is stirred and mixed, which reduces the practicality of this utility model. At the same time, a large amount of asphalt gas will be generated during the heating of the asphalt mixture. The asphalt gas needs to be adsorbed and filtered through an activated carbon block. When the activated carbon block needs to be replaced, the stirring and heating work needs to be stopped. This operation will affect the working efficiency of this utility model.

[0004] To this end, we proposed an asphalt concrete mixing instrument to solve the above-mentioned drawbacks. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The utility model adopts a piston, a connecting shaft and a concave scraper. When the asphalt concrete mixing instrument is actually used, the control panel is used to extend and retract the second electric telescopic rod, and the two groups of pistons are driven to move left and right through the mounting frame and the connecting shaft. When the feed hopper is located above the gap between the two groups of pistons, the cover plate is pulled out, and the asphalt mixture can be poured into the mixing drum through the feed hopper. When the addition is completed, the second electric telescopic rod is extended. When the gap between the two groups of pistons is misaligned with the feed hopper, the control panel is used to operate the electric heater and the drive motor. The electric heater can heat the asphalt mixture inside the mixing drum, and the output end of the drive motor can drive the main gear The wheel rotates, and since the main gear and the driven gear are meshed with each other, the rotating main gear can push the driven gear, and the rotating driven gear can drive two sets of concave scrapers and multiple sets of stirring blades to rotate through the connecting shaft.

The lower ends of the two groups of activated carbon blocks respectively abut against the two groups of sealing covers to ensure that there is a gap between the two groups of sealing plugs and the two groups of sealing covers. When a group of activated carbon blocks needs to be replaced, the operator manually pulls out a group of sealing plugs on the same side. During this process, the two groups on the same side The telescopic spring is acted upon by its own elastic force to push a group of sealing covers on the same side, so that they gradually move into the lower ends of a group of air ducts on the same side. At the same time, the asphalt gas can be adsorbed and filtered through another group of activated carbon blocks. When a group of activated carbon blocks is replaced, the sealing plugs on the same side are reset. The lower ends of this group of activated carbon blocks can push a group of sealing covers on the same side, so that they gradually move out of the interior of a group of air ducts on the same side, waiting for the next use. The replacement of another group of activated carbon blocks can be obtained through the same operation.

[0036] Specifically, a support frame is installed on the outer wall of the mixing drum 1 .

[0037] In this embodiment, the support frame serves to support and fix the mixing drum 1 .

[0038] Working principle:

[0039] When the asphalt concrete mixing instrument is actually used, the control panel is used to extend and retract the second electric telescopic rod 17, and the two groups of pistons 2 are driven to move left and right through the mounting frame 18 and the connecting shaft 3. When the feed hopper 5 is located above the gap between the two groups of pistons 2, the cover plate 6 is pulled out, and the asphalt mixture can be poured into the mixing drum 1 through the feed hopper 5. After the addition is completed, the second electric telescopic rod 17 is extended. When the gap between the two groups of pistons 2 is misaligned with the feed hopper 5, the control panel is used to operate the electric heater 10 and the drive motor 19. The electric heater 10 can heat the asphalt mixture inside the mixing drum 1, and the output end of the drive motor 19 can drive the main gear 20 to rotate. Since the main gear 20 is connected to the slave gear 19, the main gear 20 and the slave gear 19 are connected to the main gear 20. The driven gears 21 mesh with each other, and the rotating main gear 20 can push the driven gear 21. The rotating driven gear 21 can drive the two groups of concave scrapers 15 and multiple groups of stirring blades to rotate through the connecting shaft 3. The rotating two groups of concave scrapers 15 and multiple groups of stirring blades can stir the asphalt mixture between the two groups of pistons 2. When the asphalt mixture is stirred, the control panel is used to continue to extend the second electric telescopic rod 17, and the electric gate valve 8 is opened and closed at the same time. The asphalt mixture between the two groups of pistons 2 can be discharged through the discharge pipe 7. The piston 2, the connecting shaft 3 and the concave scraper 15 can ensure that all the asphalt mixture is stirred and mixed, thereby improving the practicality of the asphalt concrete mixing instrument. According to the above operation, when the asphalt mixture between the two groups of pistons 2 is heated and stirred, the control panel is used to shorten the first electric telescopic rod 12. When the plugging head 13 is moved out of the air outlet 14, the asphalt gas can be discharged through the air outlet 14. The discharged asphalt gas can pass through the gap between the two groups of sealing plugs 23 and the two groups of sealing covers 26, and finally be discharged through the two groups of activated carbon blocks 24. The lower ends of the two groups of activated carbon blocks 24 respectively contact the two groups of sealing covers 26 to ensure that there is a gap between the two groups of sealing plugs 23 and the two groups of sealing covers 26. When a group of activated carbon blocks 24 needs to be replaced, the operator manually pulls out a group of sealing plugs 23 on the same side. During this process, the two groups of telescopic springs 27 on the same side Under the action of its own elastic force, a group of sealing covers 26 on the same side can be pushed to gradually move into the lower end of a group of air ducts 22 on the same side. At the same time, the asphalt gas can be adsorbed and filtered through another group of activated carbon blocks 24. When a group of activated carbon blocks 24 is replaced, the sealing plugs 23 on the same side are reset. The lower ends of this group of activated carbon blocks 24 can push a group of sealing covers 26 on the same side to gradually move out of the interior of a group of air ducts 22 on the same side, waiting for the next use. The replacement of another group of activated carbon blocks 24 can be obtained by the same operation. Through the provided covering cover 11, the activated carbon blocks 24 can be replaced without stopping the stirring and heating work, thereby avoiding affecting the working efficiency of the asphalt concrete mixing instrument due to the replacement of the activated carbon blocks 24.
