[0027] In detail, the conveying roller 2 is conveyed through the cooperation of the motor, the toothed belt wheel and the toothed synchronous belt structure, and the hot-rolled plate strip can be conveyed into the descaling box 4 through the transmission of the conveying roller 2;

[0028] In detail, the descaling box 4 is internally provided with a high-pressure nozzle, the high-pressure nozzle is communicated with a high-pressure pump and a descaling water tank at one end, and the descaling water sprayed by the high-pressure nozzle can wash away the oxide scale through high-pressure water.

[0030] Preferably, the several scale-breaking blocks 110 are closely fitted together. By setting the several scale-breaking blocks 110 closely fitted together, every piece of iron oxide scale on the hot-rolled strip can be hit by the scale-breaking blocks 110. At the same time, the several scale-breaking blocks 110 are all independent individuals, so that the uneven iron oxide scale on the top of the hot-rolled strip can be hit. Each scale-breaking block 110 can adapt to the changes in the surface shape of the hot-rolled strip, thereby improving the scale-breaking effect.

[0031] Example 2

[0032] like Figures 1-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a baffle assembly 200 including a sleeve plate 201, a sliding plate 202 and a rotating roller 203. The bottom of the rotating roller 203 is in contact with the top of the hot-rolled strip. The descaling box 4 has openings 206 on both sides. The sleeve plate 201 is rotatably connected to the top of the opening 206. One end of the sliding plate 202 is slidably connected to the bottom of the sleeve plate 201. A connecting plate 205 is fixedly installed at the top of the sliding plate 202. The rotating roller 203 is rotatably connected to the bottom of the sliding plate 202. Several springs 204 are fixedly installed at equal distances between the connecting plate 205 and the top wall of the sleeve plate 201. The cooperation of the sleeve plate 201 and the sliding plate 202 can effectively prevent descaling water and iron oxide scale from splashing outward. The reset action of the springs 204 can allow the hot-rolled strip to easily enter and exit the descaling box 4 without being blocked by the sleeve plate 201 and the sliding plate 202.

[0033] During operation, the hot-rolled strip is first placed on the conveyor roller 2, and then conveyed to the descaling box 4 by the conveyor roller 2. Then, the drive motor 101 is started to drive the transmission rod 102 to rotate. The transmission rod 102 drives the connecting rod 105 and the linkage rod 106 to rotate circumferentially. Then, through the cooperation between the connecting rod 107, the connecting seat 108 and the sliding rod 109, the descaling block 110 at the bottom of the telescopic rod 112 is moved downward. Then, the spring 114 resets the block. This causes the descaling blocks 110 to repeatedly hammer the hot-rolled strip, knocking off the firmly adhered iron oxide scale. The hot-rolled strip continues to be conveyed after being knocked off, and then high-pressure spraying is applied to the hot-rolled strip through high-pressure nozzles, thereby efficiently removing the iron oxide scale from the hot-rolled strip. When the high-pressure nozzles apply high-pressure spraying to the hot-rolled strip, the cooperation of the sleeve plate 201 and the sliding plate 202 can effectively prevent the descaling water and iron oxide scale from splashing outwards. The descaling water and iron oxide scale fall into the receiving frame 3 through the gap between the conveying rollers 2 for collection.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
