[0021] The desulfurized gypsum powder can be continuously conveyed by rotating the conveying screw 301. When the gypsum powder blockage is not serious, just continue to work, and the thrust during work will automatically solve the blockage. When the blockage is serious, just reverse the conveying screw 301 to convey the accumulated desulfurized gypsum powder upward, thereby reducing the accumulation of desulfurized gypsum powder and facilitating the equipment to solve the blockage. At the same time, when the cylinder 4 drives the conveying screw 301 to rise and fall, it is also easy to push the accumulated desulfurized gypsum powder loose to avoid blockage.

[0023] like Figures 1 to 3 As shown, the upper end of the material discharge component 3 is provided with a screening component 2, and the lower end of the material discharge component 3 is externally connected with a transmission component 5.

[0024] like Figure 2 and Figure 3 As shown, the screening assembly 2 includes a limit plate 201, an elastic block 202, a screening plate 203 and a toggle rod 204, and the elastic block 202 is arranged in the middle of the limit plate 201, the screening plate 203 is connected to one side of the elastic block 202 close to the central axis of the limit plate 201, and the toggle rod 204 is installed at the lower end of the screening plate 203;

[0025] When the unloading assembly 3 is raised or lowered, the lever 302 will push the lever 204, so that the screen plate 203 which is an elastic sliding structure formed between the elastic block 202 and the limit plate 201 and the bucket body 101 will shake, and the desulfurized gypsum powder on the screen plate 203 will be screened to prevent large pieces of desulfurized gypsum powder from clogging the equipment.
