PURPOSE: A liquid chemical spray system having a structure for enabling a plurality of transfer members to move by rotation of a drive shaft to uniformly spray liquid chemicals is provided which is simple in construction and low in execution cost. CONSTITUTION: A first and second drive shaft(10,20) is mounted at both ends of a rail(60) formed in a longitudinal direction at the upper part of a vinyl house, a first and second motor(30,31) for providing a turning force is mounted on one side of the first and second drive shaft, and a first and second roller(11,21) is mounted on the first and second drive shaft to move a transfer member(50) with an alternating motion on the rail. A first and second limit switch(13,23) for detecting the position of the transfer member is formed on both sides of the rail, and a control part(80) for receiving the signal of the first and second limit switch and then controlling the drive of the first and second motor is also mounted. |
