An agricultural plant protection machine and a diaphragm pump thereof are provided. The diaphragm pump (400) includes: a pump body (1) including a containing cavity; a pump cover (2) on the pump body; a diaphragm (3) arranged in the containing cavity, the diaphragm matches the pump cover so that the diaphragm and the pump cover surround to form a cavity (4); and a driving mechanism (5) arranged in the containing cavity. The driving mechanism includes a push rod (51), a coil assembly (52) and an elastic reset member (53). The push rod is connected to the diaphragm, and connected to the elastic reset member. When the coil assembly is powered on and powered off alternately, the push rod makes a reciprocating linear motion to drive the diaphragm to reciprocate relative to the pump cover so as to reduce or enlarge the cavity. When the coil assembly is powered on, the push rod moves forward under the magnetic attraction of the coil assembly; when the coil assembly is powered off, the push rod moves backward under the elastic force of the elastic reset member, and the forward and backward are two opposite directions.
