[0002] There is a hot saw cutting head process in steel production, and the end defects of high-temperature steel are removed after cutting. The cut-off part, i.e. the steel head, enters the collecting hopper through the chute, but due to excessive inertia, the steel head may pop out when collecting the steel head. There are about 10-15 steel heads ejected per shift at each cutting point. The forklift needs to perform a change hopper operation every hour on average. During the change hopper operation, the ejected steel head may hit the forklift and the forklift driver, posing a significant safety risk. In addition, a large amount of manpower and resources are required to clean the steel heads on the ground of each unloading area each time. Since the steel heads are large in size, a forklift is required to assist in the cleaning operation in the hot saw area of large bars. At least 5-7 people are required to perform the operation each time, resulting in low operation efficiency. Therefore, it is necessary to propose a device to solve the problem of steel head ejection.

[0021] As shown in Figures 1-4 The utility model provides a prevent steel head to eject's buffer device, setting in hot saw blanking mouth, buffer device includes lateral fixed plate 1, pivot 2, connecting plate 3 and buffer piece, two the lateral fixed plate 1 sets up in the both sides of hot saw blanking mouth, the top edge of lateral fixed plate 1 is set up mounting position 5, just the bottom end of mounting position 5 is the cambered surface, the both ends of pivot 2 are inserted mounting position 5 respectively, the top end of connecting plate 3 is set up butt joint hole 6, pivot 2 passes through the butt joint hole 6 of multiple connecting plate 3, with pivot 2 with connecting plate 3 rotatablely connected, the bottom end of connecting plate 3 is set up inlay position 7, the top edge of buffer piece is inlayed two connecting plate 3's inlay position 7, just buffer piece with connecting plate 3 fixed connection, buffer piece is at the outside of hot saw blanking mouth and buffer piece covers hot saw blanking mouth.

[0022] It is easy to understand that the two lateral fixed plates 1 and the pivot 2 are rotatably connected. Since the lateral fixed plate 1 is provided with the mounting position 5, the both ends of the pivot 2 can enter the mounting position 5 from top to bottom and contact with the lateral fixed plate 1. After the buffer device is installed, the steel head will first impact the buffer device when it slides out, reducing the falling speed of the steel head, thereby solving the problem of the steel head bouncing out. The buffer piece is not fixed and will be turned outward after being impacted by the steel head, so that the steel head can fall into the collecting hopper.

[0023] Further, the number of connecting plates 3 is greater than or equal to two. For example Figure 1 In the embodiment, the number of connecting plates 3 is two, which are symmetrically arranged on the buffer piece.

When the buffer piece is turned upward, the second limiting piece 9 contacts the first limiting piece 8 to limit the turning angle of the buffer piece. It is easy to understand that the first limiting piece 8 cooperates with the second limiting piece to limit the excessive turning of the buffer piece.

[0026] Further, the second limiting member 9 is detachably connected with the lateral fixing plate 1, the lateral fixing plate 1 is provided with a plurality of threaded holes from top to bottom, and the second limiting member 9 is a limiting screw rod which is threadedly connected with one threaded hole of the lateral fixing plate 1.
