Embodiment 1

[0028] According to the control requirements of the three-axis linkage simple manipulator, a photoelectric sensor is installed at the grasping position to sense the existence and maturity of the crop, so as to send a feedback signal to the PLC, and the PLC sends a signal to decide whether to grasp or not. When the crops arrive, the manipulator system starts to work, the rotating cylinder, and the extending cylinder are quickly positioned to reach above the crops, the lead screw rotates and descends, and at the same time the manipulator cylinder deflates, the manipulator claws open, the manipulator reaches the middle of the crop, the manipulator cylinder is inflated, and the crops are clamped Tight, the lead screw rotates up, the rotating cylinder starts to rotate, and the extended cylinder starts to shrink. At the same time, when the stepping motor starts to move forward to place the crops, the manipulator is quickly positioned above the specified position, the lead screw rotate...

Abstract

The invention discloses a PLC (Programmable Logic Controller) control based agricultural manipulator. When a crop arrives, a manipulator system starts to work, a rotating cylinder and an extending cylinder are quickly positioned above the crop, a screw rod is rotated and descended, and meanwhile, a manipulator cylinder is deflated, a manipulator claw expands, the manipulator reaches the middle part of the crop, the manipulator cylinder is inflated and is used for clamping the crop, the screw rod is rotated and ascended, the rotating cylinder starts to rotate, the extending cylinder starts to contract, a stepping motor starts to move forward and put the crop, the manipulator is quickly positioned above an appointed position, the screw rod is rotated and descended, the manipulator cylinder is deflated, and then the crop is put to the appointed position. The manipulator is high in efficiency. The agricultural production is facilitated to relieve the labor burden.

Description

technical field [0001] The invention relates to an agricultural mechanical equipment, in particular to an agricultural manipulator based on PLC control. Background technique [0002] Since the reform and opening up, my country's modernization drive has continued to advance, and economic development has made great progress. As the engine of this development, industry must maintain constant power and vitality. Since the beginning of the new century, the automation and intelligence of industrial production has attracted more and more attention from various countries and regions. The mechanization, automation, and even intelligence of the production process have become prominent themes. The automation and intelligence of manufacturing has become a symbol of the degree of industrial modernization of a country and region. Especially in industrial processes such as mechanical processing, discontinuous production processes such as processing and assembly naturally give birth to s...
