[0025] The stirring blade 34 comprises a stirring blade body 341 movably connected between the first linkage frame 31 and the second linkage frame 32, one side of the stirring blade body 341 is provided with a first inclined surface 343, the other side of the stirring blade body 341 is provided with a second inclined surface 344, the first inclined surface 343 and the second inclined surface 344 are parallel to each other, and neither of the first inclined surface 343 and the second inclined surface 344 is perpendicular to the water surface; a regulating rod 342 is sleeved at the middle part of the stirring blade body 341, the upper end of the regulating rod 342 is connected with the adjusting assembly 4, and the upper and lower ends of the regulating rod 342 are sleeved in the interiors of the second linkage frame 32 and the first linkage frame 31 through bearings respectively; due to the arrangement of the second inclined surface 344, when the rapid rotation is performed for transverse stirring, an upward pushing force can be provided for the mixed materials, so that the up-and-down stirring effect is realized under the action of gravity, and the mixing and stirring efficiency is greatly improved; due to the arrangement of the first inclined surface 343, the residues on the inner wall of the mixing barrel 1 can be scraped off when the first inclined surface 343 is rapidly rotated, and the scraped residues can be quickly moved downward under the cooperation of the inclined surface and gravity, and enter the discharge hole 2 under the action of centrifugal force, so as to be discharged.

[0026] The adjusting assembly 4 comprises a transmission gear frame 41 movably mounted at the top of the second linkage frame 32, a plurality of driven gears 42 are evenly distributed and meshingly connected to the outer side of the transmission gear frame 41, the plurality of driven gears 42 correspond one-to-one to the stirring blades 34, and the bottoms of the driven gears 42 are fixedly connected to the top of the regulating rod 342; due to the arrangement of the driven gears 42, when the transmission gear frame 41 is rotated, a plurality of stirring blade bodies 341 can be simultaneously driven to rotate synchronously under the cooperation of the regulating rod 342, so that the angles of the plurality of stirring blades 34 can be synchronously changed.

[0030] The working principle and use process of the utility model are as follows:

[0031] The locking ring 45 is rotated to slowly rise under the cooperation of the external threads of the transmission rod 33, and then the locking ring 45 is away from the adjusting ring 44 to release the abutment of the adjusting ring 44; at this time, the adjusting ring 44 can be rotated; due to the rotation of the adjusting ring 44, the transmission ring 43 can be rotated under the cooperation of the positioning bearing 46; due to the rotation of the transmission ring 43, the transmission gear frame 41 can be rotated; due to the rotation of the transmission gear frame 41, the plurality of driven gears 42 can be synchronously rotated; due to the rotation of the plurality of driven gears 42, the corresponding adjusting rods 342 can be rotated; then the stirring blade body 341 can be rotated under the cooperation of the first linkage frame 31 and the second linkage frame 32, that is, the angle of the stirring blade body 341 can be changed, the contact surface of the stirring blade body 341 with the mixed material can be changed, and then the stirring efficiency of the mixed material can be changed, so that the mixed stirring of bitumen with different components and properties is applicable.

[0032] After the locking ring 45 is rotated to abut against the adjusting ring 44, the driving motor is started to drive the transmission rod 33 to rotate, so that the plurality of stirring blades 34 can rotate along the inside of the mixing barrel 1, and the side of the second inclined surface 344 can be in contact with the mixed material; the mixed material can be stirred horizontally, and at the same time, the mixed material can be provided with an upward thrust, so that the mixed material can be horizontally stirred and upwardly stirred at the same time, the deposition is avoided, and the mixing and stirring efficiency is improved.

[0033] When the inside of the mixing barrel 1 needs to be cleaned after the mixing process is completed, the adjusting ring 44 is rotated to make the side of the stirring blade body 341 in contact with the inside of the mixing barrel 1, and then the locking ring 45 is reversely rotated to abut against the adjusting ring 44; at this time, the driving mechanism is started to drive the transmission rod 33 to rotate, so that the side of the first inclined surface 343 can scrape the residues on the inside of the mixing barrel 1, and the residues can move downward under the action of the inclined surface of the first inclined surface 343; at the same time, the residues can enter the discharge hole 2 and be discharged due to the centrifugal force during the rapid rotation.
