The invention relates to an intelligent tea leaf picking machine and belongs to the technical field of agricultural machinery. The machine comprises a lowering device and a control circuit, wherein the lowering device is mounted on the upper part of a walking machine; the signal input end of the control circuit is connected to tea leaf image shooting and identifying devices; a support extended forwards from the walking machine is provided with a track extended forwards and backwards; a carriage which is supported on the track and a track screw rod form a screw pair; a shearing seat which forms a sliding pair with the carriage is arranged on the carriage; the shearing seat and a carriage screw rod form a screw pair; a cutter seat which forms a lifting screw pair with a vertical screw rod is arranged on the shearing seat; a horizontal rotating movable blade is arranged on the cutter seat; a sheared edge is formed between the movable blade and a fixed blade; a negative pressure tea leaf collecting pipe which is communicated with the lowering device is arranged on the upper part of the sheared edge; the control output end of the control circuit is respectively connected with a controlled end of each motor. Compared with the prior art that tea leaves are individually picked each time, the intelligent tea leaf picking machine has the advantages that the work efficiency is greatly improved, and the needs of picking and collecting the tea leaves are met.
