Abstract: A method for detecting poor welding in welding and a related device are provided. The method includes the following. An industrial personal computer (IPC) obtains an electrical signal corresponding to an infrared light signal generated by a target weld in a first period. A start moment of the first period is not earlier than a moment at which the complete target weld is formed. The IPC determines whether the target weld has poor welding according to the electrical signal corresponding to the infrared light signal.

Abstract: A tractor suspension type automatic transplanting machine for plug tray seedlings includes land wheels, a machine frame, a three-point linkage, a seedling pickup mechanism, a plug tray conveying device, a plug tray recovery device, seedling separating and planting devices driven by land wheels, and a watering device. Through front and rear drive cylinders, the seedling pickup mechanism is driven to move front and back to pick up seedlings above plug trays and release seedlings above a seedling guide device. Juxtaposed left and right seedling pickup modules in the seedling pickup mechanism are driven by left and right drive cylinders, to move left and right and pick up seedlings after combing, and to release seedlings after separating towards left and right. Plug trays fall onto a plug tray conveyor belt of the plug tray recovery device and slides into a plug-tray-recovery stacking box.

Abstract: A monitoring system and a monitoring method for a planter includes a computer having an unit speed fusion module, a seeding flow rate monitoring module, and a decision module for theoretical rotation speed of a drive motor, a rotation speed deviation inference module, a controlling parameter tuning module, an adjusting module for rotation speed of a seeding shaft, a controlling module for rotation speed of seeding shaft and a positioning signal receiver fixed on a top of a cab for receiving a geographic position signal. The system monitors operating state parameters of the planter and accurately controls seed amount.
