Description

Technical Field

[0001] The utility model relates to the field of hazardous waste treatment equipment, and particularly relates to a working arm for mixing hazardous waste materials. Background Art

[0002] After hazardous waste is collected, it is centrally stored in a storage yard or a storage pit. Generally, chemical agents need to be applied for treatment to eliminate hazards. The hazardous waste materials to which chemical agents are applied need to be fully mixed and stirred to improve the hazardous waste treatment effect through mixing and homogenization. At present, when mixing materials, a wheel loader or a traveling crane with a grab is mostly used to repeatedly grab the materials and then let them fall freely to homogenize the materials. However, since the wheel loader needs to be operated manually at close range, the harmful components or irritating odors in the hazardous waste will disperse in the air, affecting the safety and health of the operators; although the traveling crane can be operated remotely, its running speed is slow, affecting the operation efficiency. Therefore, people hope to have a working arm that can be operated remotely and quickly to lift the clamping jaws for mixing hazardous waste materials, and can drive the clamping jaws to move in different directions for mixing operations, so as to protect the health and safety of the operators and improve the operation efficiency. In view of this, this case is generated. Content of the Utility Model
