[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0018] The present invention is further described in detail below in conjunction with the embodiments.

[0019] like Figure 1-3 As shown, a specific embodiment 1 of a multi-stage segmented crushing system provided by the utility model:

[0020] A multi-stage segmented crushing system includes a hydraulic crushing device and a multi-axis crusher. The multi-axis crusher includes a frame 1, a crushing motor 2, a reducer 3 and a crushing bin 4 are installed on the frame 1, a plurality of crushing gear shafts 5 are rotatably installed in the crushing bin 4, the crushing gear shafts 5 are arranged side by side at intervals, the main shaft of the crushing motor 2 is connected to the power input shaft of the reducer 3, all the ends of the plurality of crushing gear shafts 5 extend out of the crushing bin 4, the power output shaft of the reducer 3 is connected to one of the crushing gear shafts 5 through a coupling 6, two adjacent crushing gear shafts 5 are connected through a chain sprocket transmission pair, each crushing gear shaft 5 is evenly distributed with a plurality of crushing teeth 7, and all the crushing teeth 7 are spirally distributed on the crushing gear shaft 5;

[0021] A material drop opening is arranged at the top of the crushing bin 4 , and a hydraulic crushing device is installed at the material drop opening. A crushing discharge opening 8 is arranged at the bottom of one end of the crushing bin 4 .

[0022] The hydraulic crushing device includes a crushing bin 9, the top and bottom of which are respectively provided with a feeding port and a material outlet, and a steel filter screen 10 is provided at the material outlet; four guide columns 11 are fixed in the crushing bin 9, and two push plates 12 are provided on the four guide columns 11, and the push plates 12 can move laterally along the guide columns 11, and hydraulic cylinders 13 are installed at both ends of the crushing bin 9, and the piston rod ends of the two hydraulic cylinders 13 are respectively connected to the two push plates 12, and a plurality of groups of crushing teeth 14 are provided on the opposite sides of the two push plates 12.

[0023] The working process of the multi-stage crushing system of this embodiment is as follows: first, the compacted material with a diameter of 2m is delivered to the feeding port of the crushing bin 9 by a forklift, and the compacted material falls into the crushing bin 9, and then the two groups of hydraulic cylinders 13 are started synchronously. The hydraulic cylinders 13 push the push plates 12, so that the two push plates 12 move toward each other along the guide columns 11. During the movement of the two push plates 12, the crushing teeth 14 are used to break the large pieces of material and decompose them into small diameter materials. The small diameter of the material is about 200mm. The appearance of the crushing teeth 14 is preferably a pyramidal structure. The pyramidal structure can effectively penetrate and destroy the material. The small diameter material passes through the steel filter 10 and falls into the crushing bin 4. The large pieces of material that have not been crushed repeat the above process until all the materials can pass through the steel filter 10, and the hydraulic cylinder 13 is reset and stops moving.

[0024] The crushing motor 2 drives the reducer 3 to work, and the reducer 3 drives the crushing gear shaft 5 connected thereto to rotate. The crushing gear shaft 5 drives all the crushing gear shafts 5 to rotate through the chain sprocket transmission pair. As the crushing gear shaft 5 rotates, small-diameter materials are rotated and squeezed, and crushed from 200mm to materials smaller than 30mm.

[0025] In order to further crush smaller materials with a diameter of about 30 mm, a high-speed rotary crusher can also be provided, the high-speed rotary crusher includes a driving motor and a high-speed rotary bin 15, a rotating shaft 16 is rotatably installed in the high-speed rotary bin 15, a plurality of groups of rotating crushing discs are arranged side by side on the rotating shaft 16, and the rotating crushing discs are composed of a plurality of slices 17, the slices 17 of the rotating crushing discs are arranged in a ring array, and the driving motor is connected to the rotating shaft 16 in a transmission manner;

[0026] The top and bottom of the high-speed rotating bin 15 are respectively provided with a feed port and a discharge port, and a belt elevator 18 is provided between the crushing discharge port 8 at the bottom of the crushing bin 4 and the feed port of the high-speed rotating bin 15 .

[0027] Smaller materials fall into the belt elevator 18 through the crushing outlet 8 of the crushing bin 4, and are transported to the high-speed rotating bin 15 through the belt elevator 18. The driving motor drives the rotating shaft 16 to rotate at high speed. The rotating crushing disk in the high-speed rotating state further crushes the materials through the slices 17, and processes the materials to within 5 mm. Preferably, the slices 17 are triangular in shape, and the triangles are easier to cut materials. A number of material through holes 19 are provided on the slices 17, and the materials can flow through the material through holes 19. The high-speed rotating slices 17 can shred the materials more efficiently.
