The crushing mechanism is arranged on the frame 10 and is positioned below the frame 10, and comprises a cutter drum 50 for crushing a road surface, and the cutter drum 50 is controlled by the hydraulic system 42 to perform crushing work. The frame is provided with a crushing grading device (not shown) to ensure that the crushed material processed by the cutter drum 50 meets the grading requirement.
Elevating system is the metal material, and elevating system contains curb plate 61, and preceding crane 62 and back crane 63, and curb plate 61 sets up in the side of sword drum 50, and preceding crane 62 and back crane 63 are connected the front side and the rear side of curb plate 61 respectively and are the symmetry setting about curb plate 61.
The side plates 61 are controlled to be lifted and lowered by the hydraulic system 42. As shown in fig. 3, a stabilizer plate 70 is fixed to the lower surface of the side plate 61, the stabilizer plate 70 is formed in a sled shape and includes a horizontal plate portion and two extension plate portions extending from both ends of the plate portion, the horizontal plate portion of the stabilizer plate 70 is fixed to the lower surface of the side plate, and the two extension plate portions extend upward. The stabilizer plate 70 serves to stabilize the road surface crusher when the cutter drum 50 is in operation while contacting the ground.
The front crane 62 and the rear crane 63 have the same structure. Figure 2 illustrates the front crane 62 in detail. As shown in fig. 2, the front crane 62 includes: a first member 621, a second member 622, a third member 623, and a fourth member 624. The first member 621 is disposed below the frame 10 and is fixedly connected to the frame 10. The second member 622 is a two-stage telescopic shaft, and the first-stage shaft end of the second member 622 and the end of the first member 621 form a rotatable connection. The third member 623 has three connecting ends 623a, 623b and 623c, the connecting end 623a is fixedly connected with the second-stage shaft end of the second member 622, and the connecting end 623b is rotatably connected with the side plate 61. The fourth member 624 is fixedly attached to the connecting end 623c, and the fourth member 624 is used for mounting a wheel. The front wheels 81 of the road surface crusher are mounted on the fourth member 624 on the front side and the rear wheels 82 are mounted on the fourth member on the rear side.
As shown in fig. 1, a water spraying device 90 is disposed on the frame 10, and the water spraying device 90 is connected to the water tank 20 and is used for dust fall and temperature reduction of the cutter drum during the cutter drum crushing operation.
In this embodiment, the fixing of each component in the pavement breaker 100 may be performed by welding, bolting, or other conventional mechanical component fixing methods as required, and the rotatable connection may be performed by a hinge connection, a pin shaft and a circular hole matching connection, or other conventional rotatable connection methods.
The pavement crusher 100 can perform on-site full crushing of a cement pavement of a road, and the on-site full crushing construction method of the cement pavement of the road comprises the following steps:
before the crushing work, an engine is started, a hydraulic system drives the side plates to descend, so that the front lifting frame drives the front wheels 81, and the rear lifting frame drives the rear wheels 82 to lift and leave the cement pavement 1. This is shown in fig. 4 (a).
Step two, when the crushing work is carried out, the hydraulic system drives the cutter drum 50, so that the peripheral cutting edge of the cutter drum 50 is positioned below the cement road surface 1, and at the moment, the road surface crusher 100 sinks integrally and crushes from the surface downwards. This is shown in fig. 4 (b). In this process, the stabilizer plate 70 functions as a stabilizer for the road surface when it descends to a point where the stabilizer plate 70 contacts the cement road surface 1.
And step three, after the crushing is finished, the hydraulic system drives the side plates to ascend, the front wheels 81 and the rear wheels 82 are firstly contacted with the cement road surface, and then the positions of the front wheels 81 and the rear wheels 82 are continuously lower than the cutter drum 50 (namely the cutter drum 50 relatively ascends until the position of the cutter drum 50 is higher than the cement road surface 1). This is shown in FIG. 4 (c). In this case, the road surface crusher 100 can smoothly run on the road surface.
In the on-site full-crushing method for the cement pavement of the road, the maximum crushing depth of the cement pavement for downward crushing is 25 cm. When constructing a cement road having a thickness of less than 25cm, the depth of the overall subsidence of the road surface crusher 100 may be determined by controlling the descending distance of the side plates by a hydraulic system. The on-site full-crushing method for the cement pavement of the road is suitable for crushing the cement pavement into the cement pavement with the strength less than or equal to C50, and the cement pavement containing the reinforcing steel bar net meeting the strength range can be directly crushed. When the pavement crusher works continuously, the crushing area per day exceeds 2000 square meters. The old material after the cement road surface is broken meets the standard requirement of the regenerated stone, and can be directly used for regeneration.
The above embodiments are preferred examples of the present invention, and are not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
