[0035] Example 3

[0036] See also Figure 1-4 A device door 15 is hinged on one side of the installation frame 5 through a hinge.

[0037] Working principle: First, when the crushing grid body 1 has crushed the debris, the crushing grid body 1 will discharge the crushed debris into the slag discharge square tube 2, and then start the motor 6. The motor 6 will drive the first reciprocating screw 7 to rotate. Since the first reciprocating screw 7 is threadedly connected to the knocking plate 8, and the knocking plate 8 is slidably connected to the mounting frame 5, the rotation of the first reciprocating screw 7 will drive the knocking plate 8 to reciprocate up and down. The movement of the knocking plate 8 will knock on the bottom of the basket grid 4, thereby causing the basket grid 4 to vibrate to a certain extent;

[0038] Secondly, the rotation of the first reciprocating screw 7 will drive the first bevel gear 9 to rotate, the rotation of the first bevel gear 9 will rotate the second bevel gear 10, and the rotation of the second bevel gear 10 will drive the second reciprocating screw 11 to rotate. Since the second reciprocating screw 11 is threadedly connected to the knocking block 14, and the knocking block 14 is slidably connected to the mounting frame 5, the rotation of the second reciprocating screw 11 drives the knocking block 14 to move under the influence of the thread, and the knocking block 14 moves to knock on the side of the basket grid 4. The knocking block 14 and the knocking plate 8 knock the basket grid 4 to cause it to vibrate, so that the crushed debris can be quickly screened, ensuring the screening effect of the basket grid 4;

[0039] Finally, when it is necessary to maintain the internal structure of the installation frame 5, open the equipment door 15, then rotate the limit plate 17 so that it is located at the bottom of the equipment door 15, and support the inner side of the equipment door 15 through the limit plate 17, so as to facilitate the staff to perform regular maintenance on the internal structure of the installation frame 5. After the maintenance is completed, close the equipment door 15, and then rotate the rotating plate 12 so that it is located under the magnet block 18, and fix the rotating plate 12 through the magnet block 18.
