いた。2. Description of the Related Art A sintering machine generally has a structure as shown in FIG. 1, and seals a sliding portion of a pallet p, which is a cart on which raw materials are to be sucked downward, and a wind box w thereunder. In particular, the pallet of the sintering machine moves itself, and the bottom of the pallet is not flat due to load or thermal deformation. For this reason, it is important to seal the dead seal section d, which is a feed / discharge section, and a conventional seal device having a structure using a counterweight as shown in FIG. 2 or a wipe seal as shown in FIG. There has been known a device utilizing the above method or a device having a fixed dead plate as shown in FIG.

However, the bellows have an extremely short service life of 6 months, and the mounting area is very narrow, which makes it difficult to replace them. It is fixed in position. Cypress seal type: Since the wipe seal is directed upward, it is difficult to follow the seal pallet bottom surface due to falling down or clogging. Dead plate fixed type: The distance between the bottom of the pallet and the dead plate changes for each pallet.
It is necessary to provide a gap of about 0 mm, and the effect as a sealing device can hardly be expected.

FIG. 5 shows a side view of the configuration of the sealing device according to the present invention. In the figure, reference numeral 1 denotes a pallet which moves sequentially in the direction of an arrow, and 2 denotes a pallet 1 which contacts the lower surface of the pallet 1 or has a very small size. The seal plate 3 that forms the gap is a leaf spring.
Is connected to the seal plate 2 and follows the level change of the pallet 1. Reference numeral 4 denotes a rod for adjusting the follow-up amount shown in the example in which two rods are arranged. One end of the rod 4 is connected to the leaf spring 3 and the other end is connected to the support s.
