[0021] The embodiment of the present application provides a warm mixer for the production of recycled asphalt concrete, which effectively solves the technical problem that the material directly impacts the agitator inside the equipment, causing damage to the agitator blades or the agitator body, thereby affecting the normal operation and life of the agitator.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The technical solution in the embodiment of the present application effectively solves the technical problem that the material directly impacts the agitator inside the equipment, causing damage to the blades or the agitator body of the agitator, affecting the normal operation and life of the agitator. The overall idea is as follows:

[0024] In view of the problems existing in the prior art, the utility model provides a warm mixer for producing recycled asphalt concrete, which comprises a warm mixer cover 1, a feed hopper 2 is fixedly installed on the outside of the warm mixer cover 1, a motor 3 is fixedly installed on the outside of the feed hopper 2, a rotating mechanism is arranged inside the feed hopper 2, the rotating mechanism comprises a rotating shaft 4, a driving gear 5, a transmission gear 6, a connecting shaft 7, a rotating disk 8 and an opening 9, the rotating shaft 4 is rotatably connected to the inside of the feed hopper 2, the driving gear 5 is fixedly connected to the outside of the rotating shaft 4, the transmission gear 6 is located above the driving gear 5, the driving gear 5 is meshed with the transmission gear 6, the connecting shaft 7 is fixedly installed on the upper surface of the transmission gear 6, the rotating disk 8 is fixedly installed on the end of the connecting shaft 7 away from the transmission gear 6, the rotating disk 8 is rotatably connected to the inside of the feed hopper 2, the opening 9 is opened on the outside of the rotating disk 8, and the motor 3 outputs activity that runs through the feed hopper 2 One end is fixedly connected to the outside of the rotating shaft 4, and a rotating disk 8 is set to cooperate with the motor 3. When the equipment is turned on, the material enters the interior of the equipment from the feed port. At this time, the motor 3 starts to drive the rotating shaft 4 to rotate. At this time, the driving gear 5 rotates with the rotating shaft 4. At this time, the transmission gear 6 meshes with the driving gear 5 to rotate. At this time, the connecting shaft 7 rotates with the transmission gear 6. At this time, the rotating disk 8 rotates with the connecting shaft 7. When the material falls onto the rotating disk 8, part of the material is blocked by the rotating disk 8 so that the material stays on the upper surface of the rotating disk 8, and part of the material flows into the interior of the equipment from the opening 9. The material on the rotating disk 8 flows into the interior of the equipment as the rotating disk 8 rotates. Both parts of the material are blocked to a certain extent, thereby reducing the impact force brought by the descent of the material, avoiding the material directly impacting the agitator to cause damage to the agitator blades or the agitator body, ensuring the normal operation of the agitator, and extending the service life of the agitator.

[0025] A protective box 10 is fixedly installed on the outside of the rotating shaft 4, and the driving gear 5 and the transmission gear 6 are both located on the inner side of the protective box 10. The connecting shaft 7 movably passes through the inner side of the protective box 10 to provide protection for the driving gear 5 and the transmission gear 6 to prevent the material from getting stuck in the driving gear 5 and the transmission gear 6. A limit ring 11 is fixedly installed inside the feed hopper 2, and the rotating disk 8 is rotatably connected to the outside of the limit ring 11 to provide support for the rotating disk 8.

[0026] A protective cover 12 is placed on the outside of the motor 3, and a plurality of vents 13 are opened on the outside of the protective cover 12. A threaded rod 14 is fixedly installed on the outside of the mixer cover 1, and a nut 15 is threadedly connected to the outside of the threaded rod 14. The protective cover 12 is slidably connected to the outside of the threaded rod 14. A limit plate 16 is fixedly installed on the outside of the mixer cover 1, and the limit plate 16 is composed of a concave body plate and a rectangular plate. The limit plate 16 fits with the outside of the protective cover 12, and the limit plate 16 is convenient for directly installing the protective cover 12 without adjusting the installation position of the protective cover 12. By setting the protective cover 12 and cooperating with the vents 13, the protective cover 12 is placed on the outside of the motor 3. At this time, the protective cover 12 is slidably connected to the outside of the threaded rod 14. At this time, the nut 15 is threadedly connected to the outside of the threaded rod 14 to fix the protective cover 12. The protective cover 12 provides protection for the motor 3 to prevent other objects from directly hitting the motor 3, thereby reducing the risk of mechanical damage.

[0027] Working principle:

[0028] In the first step, the protective cover 12 is arranged to cooperate with the vent 13, and the protective cover 12 is placed outside the motor 3. At this time, the protective cover 12 is slidably connected to the outside of the threaded rod 14. At this time, the nut 15 is threadedly connected to the outside of the threaded rod 14 to fix the protective cover 12. The protective cover 12 provides protection for the motor 3 to prevent other objects from directly hitting the motor 3, thereby reducing the risk of mechanical damage;

[0029] The second step is to set a rotating disk 8 and cooperate with the motor 3. When the equipment is turned on, the material enters the interior of the equipment from the feed port. At this time, the motor 3 starts to drive the rotating shaft 4 to rotate. At this time, the driving gear 5 rotates with the rotating shaft 4. At this time, the transmission gear 6 meshes with the driving gear 5 to rotate. At this time, the connecting shaft 7 rotates with the transmission gear 6. At this time, the rotating disk 8 rotates with the connecting shaft 7. When the material falls onto the rotating disk 8, part of the material is blocked by the rotating disk 8 so that the material stays on the upper surface of the rotating disk 8, and part of the material flows into the interior of the equipment from the opening 9. The material on the rotating disk 8 flows into the interior of the equipment as the rotating disk 8 rotates. Both parts of the material are blocked to a certain extent, thereby reducing the impact force caused by the descent of the material, avoiding the material directly impacting the agitator to cause damage to the agitator blades or the agitator body, ensuring the normal operation of the agitator, and extending the service life of the agitator.

[0030] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
