Technical Field

[0001] This utility model belongs to the technical field of rice seedling raising devices. Background Technology

[0002] With the continuous expansion of rice cultivation, the demand for rice seedling raising is increasing. However, agricultural land resources are limited, and there is a severe shortage of agricultural labor. Traditional seedling raising methods, which generally involve laying seedlings flat on the ground, require a large amount of land, creating a conflict with limited land resources and placing higher demands on seedling raising equipment. Existing automated factory seedling raising equipment is highly customized, with long design cycles, high requirements for greenhouse conditions, long installation and construction periods, and difficulties in modification and maintenance. This has hindered the promotion of automated seedling raising equipment and affected the improvement of the level of automation in seedling raising. Therefore, developing a circulating seedling raising device that can be arranged three-dimensionally in greenhouse space, and designing a modular combination mechanism that can be arranged in multiple layers based on the structural characteristics of existing greenhouses, can effectively solve the problems existing in the above-mentioned equipment.
