[0031] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0032] Example 1: An improved grate cooler mechanism, see Figures 1 to 4 , including a grate cooler body 1, a chain plate 2, a connecting beam 3, a grate plate 5 and a baffle 6;

[0033] A plurality of chain plates 2 are arranged on the conveying chain in the grate cooler body 1; the conveying mechanism in the grate cooler body 1 drives the conveying chain and the chain plates 2 to transmit; the connecting beam 3 is fixedly arranged on the top side of the chain plate 2; the inserting strip 4 fixedly arranged on the bottom side of the grate plate 5 is inserted and matched with the slot 301 opened on the top side of the connecting beam 3; the air holes on the grate plate 5 are not blocked; the baffle plate 6 is arranged at the opening at one end of the connecting beam 3 through the adjustment structure 7; wherein, the inner side of the baffle plate 6 is fixedly provided with an inserting block 601, and the inserting block 601 is inserted and matched with the positioning groove 401 opened at one end of the inserting strip 4;

[0034] The adjustment structure 7 includes a fixing plate 701 and a threaded rod 702;

[0035] The fixing plate 701 is fixed on the bottom side of the baffle 6; the threaded rod 702 is threadedly penetrated on the fixing plate 701; wherein the inner end of the threaded rod 702 is rotatably connected to the inner wall of the recess at one end of the connecting beam 3, and the outer end of the threaded rod 702 is fixed with a rotating handle 703.

[0036] The utility model has the advantages of fast installation or disassembly of the grate plate 5, efficient and convenient operation, and improved work efficiency by arranging the baffle plate 6, the insert block 601, the positioning groove 401, the fixing plate 701, the threaded rod 702 and the rotating handle 703, and solves the problem that a large number of bolts are used to connect the grate plate 5, resulting in a large workload for disassembling the bolts when cleaning the grate plate 5.

[0037] Specifically, the bottom of the insert 4 is set to a trapezoidal structure, and the insert 4 is adapted to the slot 301. The bottom of the insert 4 of the trapezoidal structure is easier to enter from the opening of the slot 301 when it is correspondingly inserted into the slot 301.

[0038] Furthermore, the bottom end of the fixed plate 701 contacts the top side of the chain plate 2, and the chain plate 2 can support the fixed plate 701 and the baffle 6 to enhance stability.

[0039] Furthermore, two guide rods 704 are symmetrically provided at the bottom of the fixing plate 701 , and the inner ends of the guide rods 704 are fixedly connected to the inner wall of the recess at one end of the connecting beam 3 , and the guide rods 704 are staggered from the threaded rods 702 .

[0040] The utility model has the advantage of guiding and limiting the fixed plate 701 that moves synchronously when the baffle plate 6 is moved by setting the guide rod 704, so as to keep the movement of the baffle plate 6 stable.

[0041] Working principle: With the device of the utility model, high-temperature cement clinker is fed into the grate cooler body 1, and a material layer of a certain thickness is laid on the grate plate 5. The cold air blown in passes through the material layer moving on the grate bed in a mutually perpendicular direction, so that the clinker can be rapidly cooled. When cleaning the grate plate 5, the handle 703 is turned, the threaded rod 702 rotates relative to the connecting beam 3, the fixed plate 701 moves outward along the threaded rod 702 and the guide rod 704, and the baffle 6 moves outward accordingly, until the insert block 601 leaves the positioning groove 401, the grate plate 5 is taken out, and the insert bar 4 leaves the slot 301. After cleaning the grate plate 5, the insert bar 4 is inserted into the corresponding slot 301 until the insert bar 4 is completely inserted into the slot 301, and the handle 703 is rotated in the opposite direction. The fixed plate 701 moves inward along the threaded rod 702 and the guide rod 704, and the baffle 6 moves inward accordingly until the baffle 6 contacts the end of the connecting beam 3. At this time, the insert block 601 is inserted into the positioning groove 401 to position the insert bar 4, thereby fixing the grate plate 5 and continuing to use it.

[0042] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
