The invention discloses a large-scale rice-wheat-production
biogas-liquid spraying device based on
pipe delivering. The
biogas-liquid spraying device comprises a spraying-
machine spraying head, a spraying head support, a
hydraulic pump, a fixing disc
pipe frame, a movable platform and a
control system. The spraying-
machine spraying head is fixedly installed on the movable platform through the spraying head support, the bottom of the spraying-
machine spraying head is connected on the
hydraulic pump through a liquid supplying
pipe, the
hydraulic pump is fixed on the fixing disc pipe frame through a pipe, and the fixing disc pipe frame is fixedly installed on the
road surface, a liquid inlet pipe and a liquid outlet pipe are arranged on the fixing disc pipe frame, the liquid outlet pipe is connected on the hydraulic pump, and the liquid inlet pipe is connected on a valve of a
biogas-liquid delivering pipe of a field. According to the large-scale rice-wheat-production biogas-liquid spraying device, a movable spraying machine, the fixing disc pipe frame and the biogas-liquid pipe are combined, the fertilization problem in large-scale farmland is solved; the device is cleverish in structure and flexible in operation, the large-scale farmland can be fully subjected to
spray irrigation through once operation, working efficiency is high, the pipe length between the device can be flexibly adjusted, and the practical effect is good.
