[0048] Detailed description of usage: In the process of recycling waste wood, the waste wood will be cut and crushed. At this time, a large amount of waste wood is put into the recycling and crushing frame 1, and the driving module 3 on one side of the recycling and crushing frame 1 is started, so that the two crushing knife rollers 4 in the recycling and crushing frame 1 can crush and cut the waste wood, and then transfer it to the conveying frame 2 for transportation with the help of the discharge end at the bottom of the recycling and crushing frame 1. In this process, the heat generated by the crushing knife roller 4 can be recycled with the help of the waste heat drying mechanism 5 set on the side wall of the recycling and crushing frame 1. First, the axial flow fan 501 on one side of the recycling and crushing frame 1 is started. , the cool air is transported to the air delivery pipe 504 through the air inlet pipe 503 by means of the guide frame 502, and then transported to the jet pipe 519 through the air outlet pipe 505, and finally guided out by means of the nozzle 520 on the lower surface of the jet pipe 519. In this process, the heat generated by the crushing roller 4 during the crushing and cutting is guided through the guide plate 508 and the connecting plate 510 that slide against the surface, so that the heat is introduced into the interior of the air delivery pipe 504, so that the cold air is heated after contacting the heat, and the cold air is converted into hot air. At this time, the hot air is used for further drying the crushed waste wood;

[0049] When the broken waste wood is dried by means of the jet pipe 519, the position of the jet pipe 519 can be adjusted and limited by means of the adjustment mechanism 6 arranged on one side of the fixing frame 522, so that the entire jet pipe 519 can be deflected and dried at multiple angles. By starting the servo motor 608, the servo motor 608 drives the first transmission rod 609 and the second transmission rod 610 to rotate, thereby driving the deflection block 607 on one side of the adjustment plate 601 to rotate, and at the same time, the upper end of the deflection block 607 slides The annular rack 611 drives the gear 612 fixed on the arc surface of the rotating rod 602 to mesh and rotate. At this time, the position of the entire jet pipe 519 will be rotated by the gear 612. When the jet pipe 519 does not need to be rotated at an angle, it is only necessary to rotate the limiting shaft 605 on the upper end of the limiting frame 606 to allow the limiting frame 606 to slide along the limiting rod 613. At the same time, the limiting frame 606 is plugged and fixed with the limiting hole 604 opened on the surface of the gear 612 by the tensile force generated by the first spring 603.

[0050] When the crushed and cut waste wood is transferred to the surface of the conveying frame 2 with the help of the discharge end of the recycling and crushing frame 1, it can be leveled and prevented from stacking with the help of the anti-stacking mechanism 7 arranged on the surface of the conveying frame 2, and the driving motor 704 on the surface of the connecting frame 701 is started to drive the eccentric block 705 to rotate, so that the eccentric block 705 drives the moving frame 707 to slide along the auxiliary rod 712, and reciprocates with the help of the extrusion force generated by the second spring 709, and the moving frame 707 will drive the entire connecting frame 711 and the second screen frame 703 to move horizontally, so that the first screen frame 702 and the second screen frame 703 are misaligned, and at the same time, the crushed wood is transported to the surface of the second screen frame 703 with the help of the guide piece 708 rotating on one side of the second screen frame 703 for reciprocating vibration screening and leveling operation to avoid stacking.
