Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

The invention relates to a hydraulic rolling head, which belongs to a part of a main steel bar recovery device in a full-automatic concrete beam; wherein, carry out full-automatic broken recovery unit's aim at with concrete beam 1 to the concrete beam, carry out the concrete breakage, then take out reinforcing bar wherein, especially cut off, clear up thin stirrup, remain thick main reinforcement, cut as required to it, convenient recycle improves recycle.

As shown in fig. 1, the overall structure schematic diagram of the full-automatic crushing and recycling device for the concrete beam comprises a material conveying table 2, a crusher 3, a rolling crusher 4, a waste output machine 5, a main steel bar shearing machine 6 and a main steel bar collecting machine 7.

The hydraulic roller head of the invention is part of the roller crusher 4.

The whole structure of the rolling crusher 4 is shown in fig. 2, and a workbench 41 is arranged on the rolling crusher; and a rolling device 42, a flat pressing device 43 and a rolling shear device 44 are sequentially arranged above the workbench. As shown in fig. 3, the rolling device 42 is mounted on a lifting driving device 425, and the lifting driving device 425 can be used for driving the hydraulic rolling head to vertically lift, so as to change the distance between the hydraulic rolling head and the working table 41 and perform the function of crushing.

The hydraulic rolling head of the present invention has a structure as shown in fig. 4, specifically, a rolling shaft 421, both ends of which are provided with rolling seats 422, and a rolling rotation driving device 424 is installed outside the rolling seats 422, for example, a hydraulic motor device may be adopted; a plurality of rolling cutters are arranged on the rolling shaft 421; the rolling knives are arranged at intervals, and every two adjacent rolling knives are in a neutral position, so that main steel bars which are horizontally arranged can pass through the rolling knives in a lossless manner.

As shown in fig. 5, the rolling cutter is divided into a plurality of rolling blades 423 along the circumferential direction; after the rotation, the function of breaking concrete blocks can be better performed, and the concrete blocks are pressed and broken by the end of the rolling blade 423.
