The present invention relates to a novel agrochemical pumping device which, during agrochemical pumping for agrochemical spraying, can obtain pumping pressure and efficiency higher than conventional devices, which provides a substantially inexpensive, simple, and highly efficient structure, and which is free from malfunctioning and has substantially improved user convenience. Specifically, an agrochemical liquid integrated supply recess (260) and an agrochemical liquid integrated output recess (270) are formed on left and right sides of a body (10),respectively; agrochemical liquid intake recesses (270, 370) and agrochemical liquid intermediate intake recesses (280, 380) are formed between cylinders (410, 410') on one side and the agrochemical liquid integrated supply recess (260) so as to communicate with each other, respectively; separate detachable upper and lower binding caps (500, 500') are fastened to the upper and lower sides of the body (10) by bolts, the upper and lower binding caps (500, 500') containing fresh water spaces (510, 510', 520, 520') and check valves (241, 241', 341, 341') and having agrochemical liquid discharge recesses (530, 530') formed on the right side thereof; first pumping agrochemical liquid output recesses (540, 540') are formed between the fresh water spaces (510, 510') on one side and the fresh water spaces (520, 520') on the other side, the fresh water spaces (510, 510', 520, 520') being configured inside the upper and lower binding caps (500, 500'), so as to output the agrochemical liquid, which has been pumped from one side, backwards to the other side, and second pumping agrochemical liquid output recesses (550, 550') are formed between the fresh water spaces (520, 520'), which are positioned on the upper end of the right side, and the agrochemical liquid discharge recesses (530, 530'). |
