In recent years, with the continuous improvement of Chinese laver cultivation technology and techniques, the scale of laver cultivation has been expanding, but the backward harvesting equipment and structural shortage of labor have become the main factors limiting the further development of the Chinese laver cultivation industry. The article introduces the three existing methods and harvesting characteristics of pumping type, shearing type, and rolling type laver harvesters with different principles and structures at home and abroad were reviewed, compares the advantages and disadvantages of various harvesting equipment technologies, analyzes the problems of low theoretical design level of mechanical structure, poor integration of supporting facilities and equipment in China's harvesting equipment technology, etc. The research on the biomechanical characteristics of the laver, the optimal design of the mechanical structure, the intensification of the harvesting equipment system, and intelligence are proposed as the countermeasures for the development of Chinese laver mechanized harvesting technology and equipment.
