[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.
[0024] like Figure 1As shown, this embodiment provides a super large crushing ratio multi-roll crusher, including an upper box body 8, a lower box body 1, a material mouth cup and a bracket 12. Among them, the upper box body 8 and the lower box body 1 are fixedly connected by a bolt group, and the upper box body 8 and the lower box body 1 are both welded by steel plates and steel frames, so the upper box body 8 and the lower box body 1 are both hollow.
[0025] Two coarse crushing tooth rollers 7 are detachably installed in the upper box body 8, and the two coarse crushing tooth rollers 7 are arranged in parallel, and the axes of the two coarse crushing tooth rollers 7 are in the same horizontal plane. The two coarse crushing tooth rollers 7 are used to crush large pieces of materials into small pieces, so the two coarse crushing tooth rollers 7 turn in opposite directions. Among them, a bearing cup 3 is installed at one end of the coarse crushing tooth roller 7, and the bearing cup 3 is fixedly installed with the upper box body 8 through a bolt group. At the same time, the other end of the coarse crushing tooth roller 7 is rotatably connected with the upper box body 8 through a seat bearing. A large pulley 6 is fixedly installed at the end of the coarse crushing tooth roller 7 that passes through the bearing cup 3.
[0026] Two fine crushing tooth rollers 4 are arranged in parallel in the lower box 1, and the axes of the two fine crushing tooth rollers 4 are on the same horizontal plane, but the two fine crushing tooth rollers 4 turn in opposite directions. At the same time, the axes of the coarse crushing tooth rollers 7 in the same row are on the same vertical plane as the axes of the fine crushing tooth rollers 4. Similarly, a bearing cup 3 is installed at one end of the fine crushing tooth roller 4, and the bearing cup 3 is fixedly installed on the upper box 8 by a bolt group. This end of the fine crushing tooth roller 4 passes through the lower box 1 and is fixedly connected to the small pulley 2. The adjacent large pulley 6 is connected to the small pulley 2 by a belt 5, and the other end of the fine crushing tooth roller 4 is rotatably connected to the lower box 1 by a seat bearing.
[0027] In this embodiment, the coarse crushing tooth roller 7 and the fine crushing tooth roller 4 in the same row are driven by the same motor, so that the coarse crushing tooth roller 7 and the fine crushing tooth roller 4 in the same row have the same direction of rotation, which can save part of the manufacturing cost.
[0028] In this embodiment, the feed port 11 of the feed port cup is in an inverted ladder shape, and the feed port cup is detachably mounted on the top of the upper box body 8. Specifically, the feed port cup includes a left feed block 9 and a right feed block 10, each of which is in a right-angle ladder shape. At the same time, the left feed block 9 and the right feed block 10 are both hollow boxes, and the inclined surfaces of the left feed block 9 and the right feed block 10 are arranged oppositely, and the gap between the left feed block 9 and the right feed block 10 forms the feed port 11.
[0029] In this embodiment, the bracket 12 is detachably mounted on the bottom of the lower box 1, and the discharge plate 13 is fixedly mounted on the bracket 12. Specifically, the bracket 12 includes four legs, which are respectively fixedly mounted on the four corners of the lower box 1. One end of the discharge plate 13 is fixedly connected to two legs in the same row, and the other end of the discharge plate is tilted downward and fixedly connected to the other two legs in the same row. The discharge plate 13 is dustpan-shaped, which can prevent fine materials from being shaken out from the side of the discharge plate 13.
[0030] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
