[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid, mostly existing in liquid or semi-solid petroleum form. Asphalt is an organic gelling material that is waterproof, moisture-proof and anti-corrosive. Asphalt is mainly used in industries such as coatings, plastics, rubber, and road paving. When using asphalt, it needs to be stirred and mixed with a variety of materials.
[0003] In the prior art, an asphalt stirring device usually starts stirring after pouring raw materials into a mixing barrel. After the inner wall of the mixing barrel has been used for a long time, the inner wall of the mixing barrel cannot be cleaned in time, and asphalt mortar will accumulate on the inner wall of the mixing barrel, which not only causes material waste, but also reduces the volume of the mixing barrel and reduces the amount of stirring and mixing. At the same time, the existing stirring member drives the blades extending outward through the connecting shaft to mix the asphalt, and the stirring efficiency is low. When the asphalt mortar accumulates on the inner wall of the mixing barrel, it is easy to interfere with the blades, causing damage to the blades. In addition, there are dead angles in the mixing of asphalt by the existing blades, resulting in uneven mixing. Utility Model Content
