Embodiment 1

[0030] like Figure 1 to Figure 6As shown, a tunnel engineering concrete processing equipment includes a box body 1, the top of the box body 1 is provided with a feeding port 2 for adding waste ore or construction waste and other materials into the box body 1, and the bottom of the box body 1 is a There is a discharge port 3 on the side for discharging the crushed aggregate. The box body 1 is provided with a primary crushing mechanism. The primary crushing mechanism includes a left-right symmetrical dynamic pressure block 4 and a fixed pressure block 5. The dynamic pressure block 4 and Between the constant pressure blocks 5, there is a feeding channel 6 located below the feed port 2. The inner sides of the dynamic pressure block 4 and the constant pressure block 5 are respectively provided with triangular teeth. Squeeze the material entering the material passage 6, and crush the material for the first time. The distance between the dynamic pressure block 4 and the fixed pressu...

Embodiment 2

[0041] like Figure 7 and Figure 8 As shown, the difference between this embodiment and the first embodiment is that a plurality of first arc push blocks 25 are evenly spaced on the outer peripheral surface of the large disc 13 , and the left side of the push plate 9 corresponds to the position of the large disc 13 . There is a first arc-shaped bump 26 that matches the first arc-shaped push block 25; the outer peripheral surface of the small disc 16 is evenly spaced with a plurality of second arc-shaped push blocks 27. A second arc-shaped projection 28 matching the second arc-shaped push block 27 is respectively provided at the two ends corresponding to the position of the corresponding disc group 14 .

[0042] When the large disc 13 rotates to the right side of the installation shaft 12 , the first arc-shaped push block 25 on it is driven to connect with the first arc-shaped projection 26 on the push plate 9 , and as the large disc 13 moves When the large disc 13 rotates u...

Abstract

The invention relates to the technical field of tunnel engineering, in particular to a concrete processing equipment for tunnel engineering. A primary crushing mechanism is arranged in a box. The primary crushing mechanism includes a dynamic pressure block and a fixed pressure block. The left side of the dynamic pressure block is fixedly installed with a left-right extension. The left end of the sliding rod is fixedly installed with a push plate, a spring is connected between the push plate and the left side wall of the box, and a mounting shaft extending front and rear is rotated and installed on the moving frame, facing the middle of the push plate. A large semi-circular disc is fixed and installed coaxially, and disc sets are respectively provided on the installation shafts at the front and rear ends of the push plate. The disc sets include a movable sleeve and a plurality of small discs; Cooperate with the driving part to drive the movable sleeve to slide along the installation shaft, so as to adjust the range of the opening at the lower end of the dynamic pressure block and the fixed pressure block, and then adjust the size of the aggregate obtained by primary crushing; Thereby, the specifications of the aggregates obtained by secondary crushing are synchronously adjusted.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a concrete processing equipment for tunnel engineering. Background technique [0002] Tunnels are engineering structures buried in the ground, and it is a form of human utilization of underground space. Concrete is required for tunnel construction. Concrete is prepared from cementitious materials, granular aggregates (also known as aggregates), water, admixtures and admixtures added when necessary in a certain proportion. A building material that is formed, cured and hardened. [0003] At present, aggregate is one of the main raw materials for concrete preparation, which is usually formed by crushing waste ore or various construction wastes. In the process of crushing aggregate, the existing crushing device may get stuck when encountering large-volume ore, resulting in reduced work efficiency. [0004] The invention patent with the application number CN201710219226....
