[0037] When the gypsum is dehydrated, the gypsum is discharged to the top of the conveyor belt 4 through the gypsum storage bin 3 and is transmitted to the front side by the conveyor belt 4. At the same time, the motor 118 is started, and the output end of the motor 118 drives the turntable 119 to rotate. The turntable 119 drives the second turntable 1121 to rotate synchronously through the crawler belt 1120. At this time, the turntable 119 and the second turntable 1121 respectively drive the two rotating shafts and rotating rods 1128 to rotate, and the rotating shaft and rotating rod 1128 drives the elliptical rotating shaft 1122 to rotate. The elliptical rotating shaft 1122 drives the rotating rod 1123 to move in an elliptical trajectory. The rotating rod 1123 drives the extrusion and expansion plate mainboard 1125 to move inward, and the extrusion and expansion plate mainboard 1125 drives the extrusion plate 1126 to move inward to extrude and dehydrate the gypsum. At the same time, the extrusion and expansion plate mainboard 1125 drives the extrusion plate 1126 to move inward to extrude and dehydrate the gypsum. Block 1124 slides on the inner wall of the slide groove 114 and the outer wall of the columnar slide bar 116, increasing the stability of the extrusion and expansion plate main board 1125 when it moves inward, and at the same time, the rotating rod 1123 drives the baffle hinge plate 123 to move, the baffle hinge plate 123 drives the baffle expansion plate 121 to move, the baffle expansion plate 121 drives the L-shaped baffle connecting plate 124 to move, and the L-shaped baffle connecting plate 124 drives the baffle 125 to move. When the extrusion and expansion plate main board 1125 moves toward the side close to the gypsum, the baffle 125 moves toward the side away from the gypsum. At this time, the cover on the bottom of the hot air mechanism 5 is opened, and the hot air mechanism 5 starts to perform hot air drying on the top position of the gypsum, which accelerates the evaporation rate of water inside the gypsum and improves the dehydration efficiency. When the gypsum is dehydrated, the gypsum continues to move forward to the end of the conveyor belt 4.

[0038] like Fig.10 As shown, the hot air mechanism 5 includes two hot air blowing plate side plates 51, the inner sides of the two hot air blowing plate side plates 51 are fixedly connected with a hot air blowing main board 54, the top rear side of the hot air blowing main board 54 is fixedly connected with a bellows 55, the front and rear sides of the two hot air blowing plate side plates 51 are fixedly connected with a slide rod 52, the left and right sides of the bottom of the left and right two groups of slide rods 52 are fixedly connected with a supporting vertical rod 53, the inner walls of the left and right two groups of slide rods 52 are respectively slidably connected to the outer walls of the left and right two groups of extrusion plate slide rods 1127, the bottom of the bellows 55 is fixedly connected with a hot air blowing plate 56, the bottoms of the left and right two groups of supporting vertical rods 53 are respectively fixedly connected to the front and rear sides of the left and right sides of the top of the bottom plate 2, the bottom of the hot air blowing plate 56 is fixedly connected with a hot air blowing port 57, and the left and right sides of the bottom of the hot air blowing port 57 are respectively fitted with the tops of the two baffles 125;

[0039] When the hot air blowing port 57 at the bottom of the hot air mechanism 5 is no longer blocked, the bellows 55 is started, and the hot air inside the bellows 55 is blown toward the top of the gypsum through the hot air blowing port 57, and the hot air dries the top of the gypsum. In the process of the hot air blowing toward the gypsum, the moisture inside the gypsum is quickly evaporated, thereby achieving rapid dehydration of the gypsum. At the same time, since the squeezing plate 1126 squeezes the gypsum, the residual moisture inside the gypsum is further squeezed out, further improving the dehydration efficiency. In addition, due to the cooperation of the hot air mechanism 5 and the gypsum dehydration squeezing mechanism 1, the gypsum can maintain a certain shape during the dehydration process, avoiding the deformation or cracking of the gypsum due to dehydration. When the gypsum is dehydrated, the gypsum falls from the end of the conveyor belt 4 for collection, which is convenient for subsequent processing and use. The entire dehydration process has a high degree of automation, is simple and convenient to operate, and greatly improves the work efficiency and dehydration effect.

[0040] Working principle of the present invention: when the gypsum is dehydrated, the gypsum is discharged to the top of the conveyor belt 4 through the gypsum storage bin 3, and is transmitted to the front side by the conveyor belt 4, and the motor 118 is started at the same time, and the output end of the motor 118 drives the turntable 119 to rotate, and the turntable 119 drives the second turntable 1121 to rotate synchronously through the crawler belt 1120, and at this time, the turntable 119 and the second turntable 1121 respectively drive the two rotating shafts and rotating rods 1128 to rotate, and the rotating shaft and rotating rod 1128 drives the elliptical rotating shaft 1122 to rotate, and the elliptical rotating shaft 1122 drives the rotating rod 1123 to move in an elliptical trajectory, and the rotating rod 1123 drives the extrusion and expansion plate mainboard 1125 to move inward, and the extrusion and expansion plate mainboard 1125 drives the extrusion plate 1126 to move inward to extrude and dehydrate the gypsum. At the same time, the extrusion and expansion plate mainboard 1125 drives the extrusion plate The expansion plate slider 1124 slides on the inner wall of the slide groove 114 and the outer wall of the columnar slide bar 116, increasing the stability of the expansion plate main board 1125 when it is squeezed and moved inward. At the same time, the rotating rod 1123 drives the baffle hinge plate 123 to move, the baffle hinge plate 123 drives the expansion plate 121 to move, the expansion plate 121 drives the L-shaped baffle connecting plate 124 to move, and the L-shaped baffle connecting plate 124 drives the baffle 125 to move. When the expansion plate main board 1125 is squeezed and moved to the side close to the gypsum, the baffle 125 moves to the side away from the gypsum. At this time, the shielding of the bottom of the hot air mechanism 5 is opened, and the hot air mechanism 5 starts to perform hot air drying on the top position of the gypsum, which accelerates the evaporation rate of water inside the gypsum and improves the dehydration efficiency. When the gypsum is dehydrated, the gypsum continues to move to the front side to the end of the conveyor belt 4;

[0041] When the hot air blowing port 57 at the bottom of the hot air mechanism 5 is no longer blocked, the bellows 55 is started, and the hot air inside the bellows 55 is blown toward the top of the gypsum through the hot air blowing port 57, and the hot air dries the top of the gypsum. In the process of the hot air blowing toward the gypsum, the moisture inside the gypsum is quickly evaporated, thereby achieving rapid dehydration of the gypsum. At the same time, since the squeezing plate 1126 squeezes the gypsum, the residual moisture inside the gypsum is further squeezed out, further improving the dehydration efficiency. In addition, due to the cooperation of the hot air mechanism 5 and the gypsum dehydration squeezing mechanism 1, the gypsum can maintain a certain shape during the dehydration process, avoiding the deformation or cracking of the gypsum due to dehydration. When the gypsum is dehydrated, the gypsum falls from the end of the conveyor belt 4 for collection, which is convenient for subsequent processing and use. The entire dehydration process has a high degree of automation, is simple and convenient to operate, and greatly improves the work efficiency and dehydration effect.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
