The present disclosure provides an agricultural plant protection machine. The machine includes a frame, a liquid storage tank for storing liquid, a pipeline connected to the liquid storage tank, a nozzle, and a pump for pumping the liquid in the liquid storage tank to the nozzle. The pump includes a pump body including a liquid inlet, a liquid outlet, and a pressure relief port; a pressure relief device disposed at the pressure relief port, the pressure relief device including a valve and an elastic reset member, the valve being disposed corresponding to the pressure relief port for sealing the valve. In response to a hydraulic pressure in the pump body exceeding a preset pressure threshold, the valve is separated from the pressure relief port under the force of the liquid and the liquid flows out of the pressure relief port.
