[0002] Asphalt is an important material for construction projects. During its production and processing, it is often necessary to fully mix the base asphalt with various additives in order to achieve the purpose of asphalt modification. In order to make the mixing of the base asphalt and various additives more complete, a special shearing machine is often used.

[0003] To this end, the patent specification with publication number CN219224309U discloses a modified asphalt shearing machine with multiple temperature controls, including a heat preservation and heating device and a shearing device. The heat preservation and heating device is connected to the shearing device through a metal rod. The shearing device includes a shearing body, a shearing rod and a shearing head. A top cover is provided on the top of the shearing head, and a temperature sensor A is provided on the top cover; the shearing rod above the top cover is connected to an auxiliary stirring rod, and a temperature sensor B is provided on the auxiliary stirring rod; the heat preservation and heating device is electrically connected to the temperature sensor C. The shearing machine can not only ensure the stability of the asphalt temperature during the shearing process, but also prevent the aging of the modifier caused by the excessively high center temperature, and realize the stability of the modification during the asphalt preparation process, which is beneficial to the improvement of the accuracy and confidence of the asphalt-related experimental results, and is also beneficial to ensure safety. The above-mentioned shearing machine for asphalt production has a good mixing effect when it is used, but there are still some problems:
