Description

technical field

[0001] The invention belongs to agricultural machinery, and mainly relates to a lifting machine for seedling raising in a greenhouse. Background technique

[0002] In the traditional greenhouse seedling raising, the seedling trays are directly laid on the soil of the seedling bed. After the seedlings are raised, the seedling trays are manually lifted from the seedbed soil one by one to complete the lifting operation, which has low operating efficiency and There are many problems such as high labor intensity and high operation cost. In recent years, a mesh-type greenhouse seedling raising technology method that lays flexible belt-shaped wire mesh on the soil of the greenhouse seedbed first, and then lays seedling trays on the flexible belt-shaped wire mesh has been successfully developed, which is the starting point for seedling trays after seedling raising. The tray provides convenience. However, due to the defects in the structural design of the existing n...
