Soilless culture planting device for lettuce

Abstract

The invention relates to the technical field of soilless culture, in particular to a soilless culture planting device for lettuce. The soilless culture planting device comprises a culture bed, a transmission assembly, a mechanical arm and a mechanical claw cooperation assembly. According to the soilless culture planting device, a nutrition pot is placed in a clamping groove of a rotating plate, ahorizontal moving frame in the transmission assembly pushes a first air cylinder and the mechanical arm to move through a driving assembly, a pot body of the nutrition pot is clamped and fixed througha first mechanical clamp and a second mechanical clamp on the mechanical arm, and a paper wall part of the nutrition pot is broken through a second mechanical claw, so that the lettuce seedling culture external environment is fully opened, lettuce root system growth is prevented from being damaged, and the nutrient solution irrigation dosage is reduced; and the bottom end of the second mechanicalclaw on the mechanical arm is connected with a multipurpose mechanical finger and a mold in a screwed manner, so that pit digging and soil leveling work of fine sand on the culture bed can be automatically completed, and the labor intensity of workers and the fixing cost of soilless culture are further reduced.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to a planting device for soilless cultivation of lettuce. Background technique [0002] Lettuce is lettuce, which is rich in nutrients, cool in nature, and can relieve stomach heat. It is also listed as the three major vegetables for soilless cultivation in greenhouses together with tomatoes and cucumbers. In recent years, there is also a certain cultivation area in the suburbs of northern cities in my country. Because lettuce (semi-headed species) grows fast, changes crops quickly, and is easy to manage, it is suitable for annual cultivation. The cultivation methods include gravel cultivation, sand cultivation, and spray cultivation. [0003] During the sand cultivation process of lettuce, it is necessary to transplant the lettuce seedlings in the paper nutrient pot to the cultivation bed. Since the bottom and sides of the paper pot body of the nutrient pot are closed...

AI Technical Summary

Problems solved by technology

[0003] During the sand cultivation process of lettuce, it is necessary to transplant the lettuce seedlings in the paper nutrient pot to the cultivation bed. Since the bottom and sides of the paper pot body of the nutrient pot are closed, it will affect the growth environment of the lettuce, so it is necessary to transplant the lettuce Destroy it before planting. In actual work, manual tools are often used to destroy the nutrient bowl. Although the body of the nutrient bowl can be completely removed in this way, it also destroys the sandy soil growth environment of the lettuce root system. Nutrient solution deployment and irrigation must be carried out; at the same time, the work of digging pits, transplanting and flat soil requires a lot of manpower, which increases the fixed cost of lettuce soilless cultivation
