[0021] Please refer to Figure 1-5 , an embodiment provided by the present invention: a multi-powder material condition grate cooler step-by-step segmented cooling mechanism, including a grate cooler main body 1. A side square groove 11 is opened on the front side of the front end of the grate cooler main body 1. A U-shaped frame 12 is fixedly arranged inside the grate cooler main body 1. An adjusting mechanism 2 is arranged at the bottom end of the grate cooler main body 1. The adjusting mechanism 2 includes an installation box 21, a sub-gear 22 and a driving component 23. Two groups of sub-gears 22 are inserted into the rear wall of the installation box 21. The bottom ends of the two groups of sub-gears 22 are engaged inside the rear U-shaped frame 12. A driving component 23 is arranged at the front end of the installation box 21. A segmentation mechanism 4 is installed inside the installation box 21. The segmentation mechanism 4 includes a cooling box 41 and a segmentation partition 42. The segmentation partition 42 is fixedly arranged at the top end of the cooling box 41. Circular air holes 43 are opened on the surface of the segmentation partition 42. A temperature reduction mechanism 3 is installed outside the right end of the installation box 21. The temperature reduction mechanism 3 includes a fixing plate 31, a cold air blower 32 and a connecting hose 33. The cold air blower 32 is installed on the upper side of the fixing plate 31. Four groups of connecting hoses 33 are installed on the cold air blower 32. The left ends of the four groups of connecting hoses 33 are connected inside the cooling box 41.

[0022] Furthermore, a rack plate 121 is fixedly arranged inside the U-shaped frame 12, and the rack of the rack plate 121 is installed upward, which is convenient for the installation box to move.

[0023] Furthermore, four groups of moving wheels 213 are fixedly arranged at the bottom end of the installation box 21. A hydraulic oil pump 212 is installed at the center inside the installation box 21. Fixed rods 211 are installed at the four corner positions inside the installation box 21.
