Detailed Description

The technical solution of the present invention is described in detail below. The embodiments of the present invention are only used for illustrating the technical solutions of the present invention and not for limiting, although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced with other equivalent solutions without departing from the spirit and scope of the present invention, which should be covered by the scope of the claims of the present invention.

Fig. 1 is a schematic view of an embodiment of the scrap crusher of the present invention, and fig. 2 is a schematic view of another angle of the scrap crusher shown in fig. 1. As shown in fig. 1 and 2, the scrap crusher of the present embodiment includes a frame body 300 on which a material container 310 is provided for placing a scrap to be crushed and for accommodating a mechanism for crushing the scrap. In order to crush the steel material, at least 1 group of crushing mechanisms is provided, including a first crushing mechanism 100 and a second crushing mechanism 200, and the first crushing mechanism 100 and the second crushing mechanism 200 are arranged in parallel.

The first crushing mechanism 100 includes a first crushing roller 110, a first planetary reducer 120, and a first hydraulic motor 130, both ends of the first crushing roller 110 are erected on both sides of the material container 310, the first hydraulic motor 130 is mounted on the first planetary reducer 120 to drive the first crushing roller 110 to rotate, and the first planetary reducer 120 is connected to the first crushing roller 110. In this embodiment, the first crushing mechanism 100 includes 2 sets of the first planetary reducer 120 and the first hydraulic motor 130, which are respectively connected to two ends of the first crushing roller 110, so as to facilitate adjustment of the rotation speed and increase the output torque.
