Description

Technical Field

[0001] The utility model relates to the technical field of concrete production, in particular to a cold mix asphalt concrete mixing device. Background Art

[0002] Cold mix asphalt concrete is a special type of concrete. Compared with traditional hot mix concrete, it does not require heating during the production process. This concrete is mainly composed of crushed stones, cement, water and asphalt, and needs to be stirred and mixed during the concrete production process.

[0003] For example, the Chinese patent discloses: a cold mix epoxy asphalt concrete mixing and production device, patent number: CN220450609U. By driving the raw materials through a sector sieve by a brush plate, large particles that are not conducive to use can stay on the surface of the sector sieve, and the particles that meet the specifications can pass through the sector sieve and be input into the interior of the mixing chamber for screening. The large particles will fall into the slag chute under the drive of the brush plate.

[0004] However, during the implementation of the above technical solution, it is found that there are at least the following technical problems: after screening the large pieces of materials by the above device, the materials are dropped and collected into the slag collection box, and it is necessary to perform secondary crushing treatment on the large pieces of materials and perform mixing and stirring operations again. It is impossible to perform crushing treatment during the mixing process, which increases additional operation steps and reduces production efficiency. Summary of the Utility Model

It is impossible to perform crushing treatment during the mixing process, which increases additional operation steps and reduces production efficiency.

[0009] A cold mix asphalt concrete mixing device includes a mixing barrel. A motor is fixedly connected to the upper end of the mixing barrel. A stirring rod is sleeved on the outer surface of the motor. The stirring rod is rotatably connected inside the mixing barrel. A filter plate is slidably connected inside the mixing barrel. Two truncated cylindrical blocks are rotatably connected inside the mixing barrel. Both of the two truncated cylindrical blocks are on the same horizontal line as the filter plate. Synchronous wheels are sleeved on the outer surfaces of the stirring rod and the two truncated cylindrical blocks. Synchronous belts are sleeved on the outer surfaces of the two groups of synchronous wheels. A crushing mechanism is sleeved on the outer surface of the stirring rod. The crushing mechanism includes crushing knives, and the crushing knives are sleeved on the outer surface of the stirring rod.

[0010] Preferably, a feeding pipe is sleeved inside the mixing barrel.

[0015] (III) Beneficial effects

[0016] First, start the motor. The output shaft of the motor drives the stirring rod to rotate for stirring and mixing. During the rotation of the stirring rod, the synchronous wheel is driven to rotate. The synchronous wheel drives another group of synchronous wheels to rotate through the sleeved synchronous belt. The two truncated cylindrical blocks are driven to rotate through the synchronous wheels. During the rotation of the two truncated cylindrical blocks, the filter plate is reciprocally pushed to slide inside the mixing barrel. The materials are screened by the sliding of the filter plate. The large pieces of materials are screened and blocked above the filter plate. During the rotation of the stirring rod, the crushing knives are driven to rotate to finely crush the large pieces of materials, so that the large pieces of materials are effectively crushed and broken. The crushed materials are more easily and evenly mixed with other particles, thereby improving the working efficiency and product quality of the mixing equipment.

[0017] Second, during the feeding process, the materials are put into the feeding hopper and the baffle is rotated by the weight of the materials themselves. At this time, the materials fall into the mixing barrel along the feeding hopper. When the feeding of the materials is completed, the weight generated by the materials disappears. The tension spring drives the connecting rod to rotate and reset. During the rotation of the connecting rod, the pressing rod is driven to rotate by extrusion to drive the rotating column to rotate. The baffle is driven by the rotating column to reset to block the feeding hopper, avoiding the dust generated during the concrete mixing process from floating out. There is no need for manual shielding and protection, which is beneficial to protecting the surrounding environment and air quality and improving the comfort and safety of the working environment.
