Description

Technical Field

[0001] The utility model relates to the technical field of water washing and screening, in particular to a water washing and screening device for highway test and detection. Background Art

[0002] Highway engineering refers to the survey, measurement, design, construction, maintenance, and management of highway structures. Highway engineering structures include: roadbed, pavement, bridges, culverts, tunnels, drainage systems, safety protection facilities, greening and traffic monitoring facilities, as well as houses, workshops, and other service facilities used for construction, maintenance, and monitoring. In order to ensure the quality of highway construction, it is necessary to conduct experimental tests on raw materials. The surface of the raw materials to be tested will be attached to soil, and the raw materials will be mixed together, so the corresponding raw material washing and screening device for testing is required.

[0003] Chinese utility model CN214766864U discloses a raw material water-washing and screening device for highway engineering test and detection. The raw material water-washing and screening device for highway engineering test and detection puts the raw material from the feed funnel into the mixing drum, and injects water into the mixing drum through the water injection port. The switch controls the motor to work, and the output end of the motor drives the rotating shaft to rotate. The stirring rod fixedly connected to the outer wall of the rotating shaft stirs the raw material mixed with water, and the raw material is fully cleaned, so that the raw material is fully separated, which is beneficial to improve the accuracy of the test and detection. However, during the water system process of the raw material water-washing and screening device for highway engineering test and detection, the stirring barrel needs to be closed first, and then the screening is performed after water washing. The separate method is difficult to continuously wash and filter, which affects the processing efficiency. At the same time, when filtering, the several inclined screen plates at the bottom are rapidly impacted by the water flow, which will cause the material to be directly washed away, resulting in inability to fully filter.
