Hereinafter, an embodiment of the present invention will be described in terms of its overall structure.
1-5, A crushing system of a scrap metal crusher for crushing scrap metal according to the present embodiment; wherein the scrap metal crusher crushing system comprises: the crushing chamber 1, the crushing chamber 1 comprises retaining walls 11, a rotor mechanism 12, a screen 13 and a discharge gate 14, wherein the two retaining walls 11 are arranged on two sides of the screen 13 along the direction parallel to the upstream and downstream, at least part of the rotor mechanism 12 is arranged between the two retaining walls 11 and at the top of the screen 13, the rotor mechanism 12 can enable waste metal to be extruded and crushed by the rotor mechanism 12 and the screen 13 through spinning, and the crushed waste metal falls to the downstream of the crushing chamber 1 through the mesh of the screen 13; the spin-rotatable discharge gate 14 is arranged at one side of the top of the rotor mechanism 12 and is communicated with the outside, and waste metal which cannot be crushed is discharged to the outside of the crushing chamber 1 through the opened discharge gate 14;
A transporting mechanism 2, wherein the transporting mechanism 2 comprises a transporting device 21 before crushing, a transporting device 22 after crushing and a protecting cover 23, wherein the transporting device 21 before crushing is connected with the upstream of the crushing chamber 1 and is used for transporting the waste metal to be crushed to the downstream crushing chamber 1; the post-crushing conveying device 22 is connected with the downstream of the crushing chamber 1 and is used for conveying crushed waste metal away from the crushing chamber 1 downstream; at least part of the pre-crushing conveyor 21 and/or the post-crushing conveyor 22 is covered by a shield 23.
Through the above structure, in use, an operator places the scrap metal upstream of the pre-crushing transport mechanism 21 and starts the transport mechanism 2 to start operating, and the track of the pre-crushing transport mechanism 21 drives the scrap metal to operate in the downstream direction of the crushing chamber 1 until all the scrap metal is conveyed into the crusher and the scrap metal crushing process is started. After the waste metal enters the crushing chamber 1, the external driving mechanism drives the main shaft 122 to start rotating, the hammer head 124 on the main shaft 122 rotates and swings along the rotating direction of the main shaft 122 and collides and extrudes with the waste metal, so that the waste metal is cut in batches, the cut waste metal is discharged through the screen 13 at the lower part of the main shaft 122 by virtue of dead weight, the waste metal falling on the screen 13 is continuously transported downstream through the transportation device 22 after crushing until the waste metal is transported to a designated area, and the next screening or classifying work is conveniently carried out.
It should be noted that in the above process, the strength of the waste metal itself may be greater than that of the rotor mechanism 12, so that the rotor mechanism 12 cannot effectively crush the waste metal, at this time, the waste metal which cannot be crushed is accumulated in the area between the two retaining walls 11 and at one side of the rotor mechanism 12 in the crushing chamber 1, and then an operator can discharge the hard waste metal which cannot be crushed outside the crushing chamber 1 through the position of the discharge gate by opening the adjacent discharge gate 14.
