[0024] A feed pipe 3 is provided on the top of the crushing box 2, and the scrap steel is poured into the crushing box 2 from the feed pipe 3 for crushing; the material guiding mechanism is arranged in the feed pipe 3, and the material guiding mechanism includes a partition 4, a guide plate 5 and a diagonal support plate 6; the partition 4 is fixedly arranged at the middle position inside the feed pipe 3, and hinge grooves 41 are provided on both sides of the bottom of the partition 4, and a rotating shaft 42 is arranged in the hinge groove 41; a hinge block 51 is provided on one side of the guide plate 5, and the hinge block 51 is rotatably arranged in the hinge groove 41, and the rotating shaft 42 is arranged in the hinge block 51, and a torsion spring 52 is arranged between the rotating shaft 42 and the hinge block 51; the diagonal support plate 6 is arranged at the bottom of the partition 4, for supporting the guide plate 5.
[0025] By setting a material guide mechanism, during the feeding process, the partition 4 divides the feed pipe 3 into two parts, and the guide plate 5 rotates in the hinge groove 41 through the hinge block 51 and the rotating shaft 42, and is supported by the diagonal support plate 6 at the bottom of the partition 4, so that the guide plate 5 guides the scrap steel to both sides of the crushing box 2, thereby achieving uniform distribution of the scrap steel. This helps the crushing mechanism to process the scrap steel more efficiently and improves the crushing efficiency. At the same time, it avoids the problem of equipment overload caused by excessive accumulation of scrap steel in the same position. It helps to protect the equipment from damage and prolong its service life. After the feeding is completed, the guide plate 5 is reset under the action of the torsion spring 52, and the feed pipe 3 is closed, thereby improving the safety of the crushing work and reducing the diffusion of dust during crushing.
[0026] The pulverizing mechanism includes a power device 7, a driving gear 81, a driven gear 82 and a pulverizing roller 8. Two pulverizing rollers 8 are arranged in the pulverizing box 2. The driving gear 81 and the driven gear 82 are respectively arranged at one end of the two pulverizing rollers 8 that penetrate the side wall of the pulverizing box 2; the driving gear 81 and the driven gear 82 are meshed with each other; the output end of the power device 7 is connected to the driving gear 81.
[0027] The driving gear 81 is driven by the power device 7 to rotate, and through the engagement with the driven gear 82, the driven gear 82 and the pulverizing roller 8 connected thereto are driven to rotate synchronously, ensuring that the two pulverizing rollers 8 can rotate at the same speed and in opposite directions, thereby improving the pulverizing efficiency of scrap steel.
[0028] Auxiliary gears 83 are provided at the other ends of the two crushing rollers 8 that penetrate the side wall of the crushing box 2, and the auxiliary gears 83 are meshed with each other.
[0029] The auxiliary gear 83 is provided to ensure the synchronization and stability of the two crushing rollers 8 during the rotation process, thereby improving the stability and reliability of the crushing process and the crushing efficiency.
