DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-5The pneumatic breaker includes a pneumatic breaker body 1 and an assembly 7. A cylinder bracket 3 is installed on the pneumatic breaker body 1, and a cylinder 4 is installed on the cylinder bracket 3. The output end of the cylinder 4 is connected to the stroke shaft 6 through a coupling sleeve 5. The stroke shaft 6 extends into the interior of the pneumatic breaker body 1, and a screening net 11 is arranged inside the pneumatic breaker body 1. The upper and lower sides of the pneumatic breaker body 1 are respectively an inlet and an outlet, and a mounting member 2 is arranged on the inlet and the outlet. The mounting member 2 is provided with a mounting ring 8, and the mounting member 2 is adapted to be installed on the assembly 7. A breaking hammer is arranged on the stroke shaft 6, and the stroke shaft 6 can be driven by the cylinder 4, so that the material in the pneumatic breaker body 1 can be broken by the breaking hammer. The broken material can be screened by the setting of the screening net 11. It is also worth noting that the specific structures and working methods of the pneumatic breaker body 1, screening net 11, cylinder 4, connecting sleeve 5 and stroke shaft 6 are all existing technologies currently disclosed on the market, and they do not belong to the main technical problems to be solved in this technical solution, so they are not elaborated in this utility model.

[0021] The assembly part 7 is fixedly arranged on the external processing device, and an assembly cavity 71 is adapted to be opened on the assembly part 7 corresponding to the mounting part 2. The assembly of the pneumatic breaker body 1 can be realized by mounting the mounting parts 2 on the feed port and the discharge port of the pneumatic breaker body 1 on the assembly part 7 on the external processing device.

[0022] Among them, a plurality of connecting cavities 9 are provided inwardly on one side of the assembly part 7 on which the assembly cavity 71 is provided, and the inner sides of the connecting cavities 9 are connected to the clamping cavities 91, and the connecting cavities 9 and the clamping cavities 91 are both connected to the assembly cavity 71. The mounting ring 8 is adapted to be installed on the outer side of the mounting part 2, and a plurality of movable blocks 81 are provided on the mounting ring 8 to extend outward, and the movable blocks 81 are adapted to the connecting cavity 9 and the clamping cavity 91. By installing the movable block 81 in the clamping cavity 91, the mutual clamping between the movable block 81 and the clamping cavity 91 can be achieved, thereby achieving the installation of the mounting part 2.

[0023] Among them, a through hole 72 is opened on the outer side of a clamping cavity 91 of the assembly part 7, and the through hole 72 is connected with the clamping cavity 91, and a bolt 82 is inserted into the through hole 72. A screw hole 83 is opened vertically in the middle of a movable block 81 of the mounting ring 8, and the screw hole 83 is adapted to the through hole 72 and the bolt 82. Through the adaptation setting between the bolt 82 and the screw hole 83, the movable block 81 on the mounting ring 8 in the assembly part 7 can be fixed, thereby preventing the mounting ring 8 from loosening and falling off after assembly.

[0024] In this embodiment, when the user needs to assemble the pneumatic breaker body 1, it is only necessary to insert the mounting member 2 at the inlet or outlet of the starter breaker body 1 into the assembly cavity 71 on the assembly part 7 on the external processing device. Then, the movable blocks 81 on the mounting ring 8 are all adapted and inserted into the connecting cavity 9, and the mounting ring 8 can be connected to the mounting member 2. Then, it is only necessary to rotate the mounting ring 8, so that the movable block 81 in the connecting cavity 9 can be rotated into the clamping cavity 91. Then, the user inserts the bolt 82 into the screw hole 83 through the through hole 72, so as to fix the mounting ring 8, thereby preventing the mounting ring 8 from loosening during subsequent use. In this way, the connection between the mounting member 2 and the assembly part 7 can be achieved, so that the pneumatic breaker body 1 can be installed.

[0025] In the utility model, the material can be crushed by the arrangement of the pneumatic breaker body 1 and the cylinder 4. By the adaptation arrangement of the movable block 81 and the card cavity 91 on the mounting ring 8, the mounting part 2 on the pneumatic breaker body 1 can be quickly installed on the assembly part 7 on the external processing device. This installation method is more convenient and is easy for the user to use later.
