Title:
MULTI-COMPONENT COORDINATED MOTION CONTROL DEVICE AND METHOD FOR AIR VIBRATION TYPE PRECISION SEEDING ASSEMBLY LINE
Document Type and Number:
WIPO Patent Application WO/2022/183523
Kind Code:
A1
Abstract:
A multi-component coordinated motion control device and method for an air vibration type precision seeding assembly line. The device comprises a seeding assembly line, a seed suction tray motion control component, a moving seed addition component (4), and a seed cleaning component (11). The seed suction tray motion control component serves as a main control object. A seed suction tray (5) is connected to a four-degree-of-freedom manipulator, and can realize any displacement in a rectangular coordinate system for cooperation with a seeding assembly line to complete the coordinated operation of seeding. The seed suction height can be adjusted with the thickness change of a seed layer in a vibrating seed tray, thereby increasing the seed suction rate. A series motion control model for seed carrying speed and seed suction tray accompanying speed is established to control the seed suction tray to complete seed metering in the process of moving along with a seedling tray at the same speed, so that the seed suction tray can cooperate with the moving seed addition component, the seed cleaning component and the assembly line to complete seeding flow process. The seeding process rhythm is adjusted while increasing the seed suction rate, and optimal coupling of seed addition, seed suction, seed carrying, seed metering and seed cleaning is achieved.
