The cover is placed below the grate gap 102, and both ends of the U-shaped baffle 14 are provided with support ears 141, and the two ends of the two support ears 141 away from the U-shaped baffle 14 are both inserted into the grate frame 1 and extend to the outside thereof, and the first limit seat 15 and the second limit seat 18 are respectively provided at positions corresponding to the support ears 141 at both ends of the outer wall of the grate frame 1, and the first limit seat 15 and the second limit seat 18 are respectively rotatably installed with threaded rods 16 and sliding rods 19 inside, and the ends of the two U-shaped baffles 14 located outside the grate frame 1 are respectively inserted into the first limit seat 15 and the second limit seat 18 and are sleeved on the outer walls of the threaded rods 16 and the sliding rods 19, and the U-shaped baffles 14 can slide inside the grate frame 1 through the rotation of the threaded rods 16.

[0025] In one embodiment, when the grate gap 102 of the grate plate of the grate cooler is used, the threaded rod 16 can be directly screwed to rotate the threaded rod 16 in the first limit seat 15, and drive the ear 141 installed on the threaded rod 16 through the threaded hole 142 to slide in the first slide groove 151 and the through groove 103, and then the sliding ear 141 drives the U-shaped baffle 14 to move in the cavity 101, and move the two adjacent U-shaped baffles 14 from the bottom of each end plate 12 and the side plate 11 to the bottom of the grate gap 102, so that the two U-shaped baffles 14 located below the grate gap 102 cover its opening, change the width of the opening of the grate gap 102, so that the cooling air can be blown in from the grate gap 102.
