TROUGH MOVING TYPE HYDROPONIC CULTURE FACILITY

摘要

PURPOSE:To save labor, efficiently enhance soil utilizing ratio in a short period and enable culture of leaf vegetable by moving a trough circulation system while spreading pitch of each trough and repeating planting, rearing and harvesting. CONSTITUTION:When harvesting and planting in operation position 20 is finished, trough 3X is moved to a direction Q perpendicular to carrying direction by two workers worked in harvesting and planting. The trough 3X laterally moved is simply moved to start end side 3 Ga of the second idler roll line 3G2 without lifting the trough 3X by trough transferring device 33 in a state coming into contact with a pitch tapped spiral rotating screw rod 4. In the second trough line 3G2, the start end side 3Ga of pitch-tapped spiral rotating screw rod 4 is empty. Therefore, the trough 3X is laterally moved up to the position and engaging pieces 16 and 16 of the trough 3X is carried on the pitch tapped spiral rotating screw rod 4 so as to engage with a spiral groove 4d1.
