The bottom end of the screw 11 is connected to the screw sleeve 10 through a thread. When the two screws 11 rotate at the same time, the baffle 9 can be driven to move up and down. A mounting shell 12 is fixed to the top outer wall of the casing 1. The top end of the screw 11 extends to the inside of the mounting shell 12 and is fixed. There is a worm wheel 14, and a worm 13 is connected between the inner walls on both sides of the mounting shell 12 through bearings. The worm 13 is meshed with the worm wheel 14. When the worm 13 rotates, it drives the worm wheel 14 and the screw 11 to rotate. One end of the worm 13 extends to the outside of the mounting shell 12 and is fixed with a driving mechanism 19. The driving mechanism 19 is used to drive the worm 13 to rotate. The driving mechanism 19 is preferably a handwheel. A protective tube 18 is fixed to the top inner wall of the casing 1. The protective tube 18 is sleeved on the outside of the screw 11 and the screw sleeve 10. By setting the protective tube 18 to be sleeved on the outside of the screw 11 and the screw sleeve 10, the dust generated by the cement clinker during cooling is not easy to adhere to the outside of the screw 11, and the screw 11 is not easy to get stuck during use.

[0023] The utility model provides an adjustable cement clinker grate cooler, which drives the worm wheel 14 and the screw 11 to rotate through the rotation of the worm 13, thereby adjusting the distance between the baffle 9 and the grate cooling bed 2, so that the baffle 9 can block the cement clinker being transported on the grate cooling bed 2, so that the thickness of the cement clinker can be adjusted, so that the cement clinker can achieve a good cooling effect.

The top end of the guide column 15 extends to the outside of the casing 1 and a stopper 17 is fixed thereto. The baffle 9 drives the guide column 15 to move up and down, so that the exposed length of the guide column 15 is changed. The scale 16 can reflect the distance between the baffle 9 and the grate cooling bed 2, and thus the distance between the baffle 9 and the grate cooling bed 2 can be intuitively displayed.

[0025] In another embodiment provided by the utility model, an air inlet 6 is provided on one side outer wall of the grate cooling bed 2, a crushing mechanism 7 is provided between the grate cooling bed 2 and the casing 1, the crushing mechanism 7 is a prior art, and the crushing mechanism 7 is used to crush the cooled cement clinker, and a fan 20 is fixed to the outer wall of one side of the casing 1, and the air outlet of the fan 20 is connected to the air inlet 6 of the grate cooling bed 2 through a pipeline, and the fan 20 is used to introduce air into the grate cooling bed 2, so that the cement clinker transported on the grate cooling bed 2 is cooled by air. An air outlet 3 is provided on the top of the casing 1, and the air inside the casing 1 flows out from the air outlet 3 for recovery; a discharge port 8 matched with the crushing mechanism 7 is fixed on the bottom outer wall of the casing 1, and the cement clinker flows out from the discharge port 8 after being crushed; a feed port 4 is provided on the top of the casing 1, and the clinker coming out of the rotary kiln enters the casing 1 from the feed port 4, and the feed port 4 is located at the top of the grate cooling bed 2, and a guide plate 5 located on the top of the grate cooling bed 2 is fixed on the inner wall of one side of the casing 1, and the guide plate 5 can accurately keep the cement clinker on the grate cooling bed 2.

[0026] Working principle: when it is necessary to adjust the thickness of the cement clinker transported on the grate cooling bed 2, the driving mechanism 19 drives the worm 13 to rotate, so that the worm 13 drives the worm wheel 14 to rotate, and the rotation of the worm wheel 14 drives the screw 11 to rotate, so that the screw 11 drives the screw sleeve 10 to move downward, and then the screw sleeve 10 drives the baffle 9 to move downward, so that the distance between the baffle 9 and the grate cooling bed 2 is adjusted, so that the baffle 9 can block the cement clinker transported on the grate cooling bed 2, so that the thickness of the cement clinker is adjusted; when the baffle 9 moves up and down, the baffle 9 will drive the guide column 15 to move up and down, so that the exposed length of the guide column 15 is changed, and the distance between the baffle 9 and the grate cooling bed 2 can be reflected by the scale 16, so that the distance between the baffle 9 and the grate cooling bed 2 can be intuitively displayed.
