Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 4, the concrete aggregate crusher in this embodiment includes a casing 1, a rotor assembly 2 is disposed in the casing 1, a breaking hammer 3 is movably disposed on the rotor assembly 2, a grate 4 is disposed below the rotor assembly 2 in the casing 1, a lateral feeding port 5 is disposed at the top of the casing 1 along an axial direction of the rotor assembly 2, and an included angle is formed between the lateral feeding port 5 and a horizontal direction.

In the practical implementation process, the stone materials are poured into the machine shell 1 from the lateral feeding port 5, the rotor assembly 2 is in the rotating process, the breaking hammer 3 strikes the stone materials to achieve breaking, and due to the lateral feeding port 5, small stone particles which are carried by the breaking hammer 3 and fly up in the tangential direction are limited in the machine shell 1 and are not prone to flying out in the lateral direction.

Since the stone material enters from the side direction and is not automatically distributed along the axial direction of the rotor assembly 2, which easily causes the abrasion of the breaking hammer 3 near the end of the lateral feeding port 5 due to long-term operation, and the breaking hammer 3 far from the end of the lateral feeding port 5 is difficult to act on the stone material, the conventional rotor structure needs to be improved, in this embodiment, the rotor assembly 2 includes a rotor shaft 21, hammer frame disks 22 and hammer shafts 23, the hammer frame disks 22 are uniformly spaced on the rotor shaft 21, the hammer shafts 23 are circumferentially symmetrically arranged on the hammer frame disks 22, the breaking hammers 3 are arranged at the gaps between the hammer frame disks 22 and are movably connected with the hammer shafts 23, the breaking hammer 3 includes a connecting part 31 and hammers 32, the connecting part 31 is used for extending into the gaps between the hammer frame disks 22 and connecting with the hammer shafts 23, and the hammers 32 are exposed out of the gaps between the hammer frame disks 22, for impacting the stone, in the embodiment, the hammer frame disc 22 is gradually reduced along the axial direction of the rotor shaft 21, the connecting part 31 of the breaking hammer 3 is gradually reduced along the axial direction of the rotor shaft 21, and the rotor assembly 2 is in a shape similar to a truncated cone. In this embodiment, there is only one rotor assembly 2, and the end of the lateral inlet 5 is located opposite to the largest hammer carrier disc 22 of the rotor assembly 2. After the stone enters the machine shell 1, the stone is firstly knocked by the breaking hammer 3 driven by the hammer frame disc 22 with larger diameter, and in the process that the stone becomes smaller, the stone rolls towards the end with smaller diameter of the rotor assembly 2 step by step, so that the breaking hammer 3 on the whole rotor assembly 2 can play a role.

In an embodiment, a blocking frame 8 is further disposed above the rotor assembly 2 in the casing 1, and the blocking frame 8 includes a plurality of cross bars parallel to each other, and a space for the hammer head 32 to extend into is formed between adjacent cross bars.
