The invention relates to the technical field of tunnel engineering, in particular to tunnel engineering concrete processing equipment which is characterized in that a primary crushing mechanism is arranged in a box body and comprises a movable pressing block and a fixed pressing block, a sliding rod extending leftwards and rightwards is fixedly mounted on the left side of the movable pressing block, and a push plate is fixedly mounted at the left end of the sliding rod; a spring is connected between the push plate and the left side wall of the box body, a mounting shaft extending front and back is rotationally mounted on the moving frame, a semicircular large disc is coaxially and fixedly mounted on the mounting shaft directly facing the middle of the push plate, disc sets are arranged on the mounting shafts directly facing the front end and the rear end of the push plate respectively, and each disc set comprises a movable sleeve and a plurality of small discs; the movable sleeve is driven to slide along the mounting shaft by adjusting the movable frame left and right and matching with the driving piece, so that the range of openings in the lower ends of the movable pressing block and the fixed pressing block is adjusted, and the specification of aggregate obtained through primary crushing is adjusted; in addition, the movable guide plate is driven to move leftwards and rightwards while the movable frame is adjusted leftwards and rightwards, so that the specification of aggregate obtained through secondary crushing is synchronously adjusted.
Description
technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to concrete processing equipment for tunnel engineering. Background technique [0002] A tunnel is an engineering building buried in the ground, and it is a form of human use of underground space. Concrete is used in the construction of tunnels. Concrete is prepared in a certain proportion from cementitious materials, granular aggregates (also called aggregates), water, admixtures and admixtures added when necessary, and is uniformly stirred and compacted. A building material formed and hardened by curing. [0003] At present, aggregate is one of the main raw materials for concrete preparation. Aggregate is usually formed by crushing waste ore or various construction waste. When the existing crushing device encounters a large ore in the process of crushing aggregates, the crushing device may be stuck, resulting in a reduction in work efficiency. [0004] The invention ...
