Reinforcing device of squat silo grain blocking door

A reinforcing device of a squat silo grain blocking door belongs to the technical field of squat silo equipment and is used for reinforcing the squat silo grain blocking door. The technical scheme isas follows: the length of the stop lever is equal to the distance between two ends of the grain blocking door; four implosion expansion bolts of the upper fixed seat and the lower fixed seat are respectively buried in cement structures at the upper end and the lower end of the grain blocking door; opposite bolt holes are formed in the opposite right-angle sides of the combined angle steel of the upper fixing base and the lower fixing base. The lead screws penetrate through bolt holes in the two pieces of angle steel, the two lead screw nuts lock the lead screws on the two sides of the two pieces of angle steel respectively, fastening holes are formed in the four corners of the other two right-angle sides of the two pieces of angle steel respectively, and the combined angle steel is connected with implosion expansi
