The invention discloses a DF37 anti-aircraft gun feeding mechanism. The DF37 anti-aircraft feeding mechanism consists of a left feeding mechanism, a right feeding mechanism and a balance base, wherein the balance base is fixed above the upper end of a swinging frame of an original gun by using four bolts; a vertical shaft is arranged on the base, and is connected with a left support and a right support at the front ends of the left feeding mechanism and the right feeding mechanism; the upper side of the vertical shaft is fixed by using a gland, a nut and an elastic gasket; the gland is fixed on the balance base by using four bolts and the elastic gasket respectively, and has a bilaterally symmetrical structure; the back ends of the left feeding mechanism and the right feeding mechanism are connected with the back walls of a left feeding mechanism and a right feeding mechanism of the original gun respectively by using fixers in order that the left feeding mechanism and the right feeding mechanism are fixed together. The DF37 anti-aircraft gun feeding mechanism has the advantages of simple structure, low price, high reliability and convenience in maintenance and repair, safety during operation is ensured, the problem that artillery shells cannot be launched in time due to short airspace time during operation is solved, and the hail-suppressing and precipitation-increasing efficiencies are increased.
