(5) separating mechanism (6) separate building waste concrete's reinforcing bar and concrete, and the concrete piece of separation falls into lower floor's conveyer belt (22) by bars strip-shaped gap, and lower floor's conveyer belt (22) end is connected with the feed inlet of jaw breaker (7), and the concrete piece is broken in advancing into formula breaker (7).
9. The working method of the detachable concrete crushing device according to claim 8, wherein the rotating tooth mechanisms (31) of the meshing material conveying mechanisms (3) on two sides of the upper layer conveying belt (21), the short shearing tooth mechanisms (41) of the surface layer crushing mechanisms (4) on two sides of the upper layer conveying belt (21), the long shearing tooth mechanisms (51) of the internal crushing mechanisms (5) on two sides of the upper layer conveying belt (21), and the distance between the roller bodies of the separating mechanisms (6) on two sides of the upper layer conveying belt (21) are adjusted through a distance adjusting mechanism (9), the distance adjusting mechanism (9) is controlled through an electro-hydraulic control system, and the working method of the electro-hydraulic control system comprises the following steps:
(1) change giving: the method comprises the steps that the distance is adjusted by taking a zero-distance position as a starting point, after an electro-hydraulic control system is started, the electro-hydraulic control system controls a hydraulic cylinder (96) to move, so that the hydraulic cylinder (96) pushes a moving block (93) to move until a rotating tooth mechanism (31), a short shearing tooth mechanism (41), a long shearing tooth mechanism (51) or a roller body collides, the pressure difference between a rod cavity and a rodless cavity of the hydraulic cylinder (96) is increased, when the pressure difference is larger than the collision pressure difference set by the electro-hydraulic control system, the hydraulic cylinder stops pushing the moving block (93), and at the moment, the adjustment of the distance value being zero is completed;
(2) adjusting the distance: from the zero-spacing position, the electro-hydraulic control system controls the hydraulic cylinder (96) to move, the hydraulic cylinder (96) controls the moving block (93), so that the rotating gear mechanism (31) or the short shearing gear mechanism (41) or the long shearing gear mechanism (51) or the roller body are far away, when the displacement sensor (95) detects that the moving distance is equal to a spacing adjusting value set by the electro-hydraulic control system, the hydraulic cylinder (96) stops moving, and at the moment, the spacing adjustment before operation is completed.
