A thickening device for uniform solidification of composite lost circulation material made up of liquid and granular lost circulation materials, comprising a base, wherein the base is provided with a side wall;

• an upper end of the side wall is provided with a detachable top cover;
• and the base, the side wall, and the top cover form a sealed chamber;
• the base is provided with a rotating support platform;
• the rotating support platform is provided with a detachable slurry cup;
• the slurry cup is provided therein with agitating shafts;
• the agitating shafts each are provided with a blade;
• a top end of the agitating shaft is connected to a threaded rod through a ball head connector, allowing the agitating shaft to rotate relative to the threaded rod;
• an upper end of the agitating shaft is provided with a second gear;
• the threaded rod is provided with a second limit platform;
• and the slurry cup comprises an inner surface provided with an inner gear ring for driving the second gear and an outer surface provided with an outer gear ring;
• the ball head connector comprises a connecting component and a limiting component;
• and the connecting component is a cylinder, wherein the threaded rod and the agitating shaft are on a same axis;
• the side wall is provided with a first limit platform, a feed inlet, and a discharge outlet;
• the first limit platform is detachably connected to a horizontal plate located above the slurry cup;
• the horizontal plate is provided with slots for front ends of the threaded rods to pass through and slide;
• the front end of the threaded rod is fastened to the horizontal plate by a nut;
• the horizontal plate is further provided with a material addition window;
• and a width of the slot is smaller than a diameter of the second limit platform;
• and
• a lower surface of the top cover is provided with a motor;
• and a rotating shaft of the motor is provided with a first gear, wherein the first gear matches the outer gear ring;
• wherein the second gear comprises a bearing;
• the bearing comprises an inner ring and an outer ring;
• the inner ring of the bearing is fitted onto the agitating shaft and provided with an L-shaped bracket;
• a lower side of a front end of the L-shaped bracket is provided with a telescopic cylinder;
• the telescopic cylinder is fitted into a spring;
• a lower surface of the telescopic cylinder is provided with a second roller;
• a circumferential surface of the outer ring of the bearing forms a gear surface, wherein the gear surface matches the inner gear ring;
• and an upper surface of the outer ring of the bearing is provided with a V-shaped groove for accommodating the second roller.
