Chain fruit pulling mechanical control system based on weight analysis

The invention relates to a chain fruit pulling mechanical control system based on weight analysis. The dragging type chain fruit pulling machine comprises an upper laying steel bar, a lower laying steel bar, a traction frame sliding locking screw, a power input shaft, a main control mechanism, a seedling supporting adjusting screw, a chain tensioning screw, a driving chain and a data configuration interface; the weight conversion device is used for determining the current fruit weight of the corresponding preset area potato growth area based on the received current reference number; and the fruit pulling triggering mechanism is used for generating a continuous digging instruction at uniform time intervals when the weight of the fruit body in the fruit body storage container is lower than the weight of the current fruit body. Through the system, the leaf distribution area of potatoes in the current planting area can be recognized, the corresponding estimated total fruit body growth amount is intelligently analyzed based on the leaf distribution area, and when the current total fruit pulling amount is lower than the analyzed estimated total fruit body growth amount, potato digging processing is requested to continue to be executed.
