Description

Technical Field

[0001] This utility model relates to the field of seedling cultivation technology, specifically a seedling cultivation rack that facilitates the adjustment of seedling height. Background Technology

[0002] Seedlings are tree seedlings with roots and trunks. All seedlings cultivated in a nursery, regardless of age, are called seedlings before they leave the nursery. Types of seedlings include: seedlings grown from seed, seedlings propagated by vegetative propagation, transplanted seedlings, and seedlings left in the nursery bed. Seedlings can also be classified as trees and shrubs. Generally, there are more tree seedlings in the north and more shrubs in the south. This is mainly due to the different growing climates. When cultivating seedlings, seedling racks and seedling trays are usually used. The shape of the holes in the trays should preferably be a square inverted trapezoid. This helps guide the roots to extend downwards, rather than the roots winding around the inner wall as in round or vertically oriented holes. Deeper holes provide better conditions for drainage and aeration of the substrate. Some trays also have ventilation holes between the holes, allowing air to circulate between the plants, keeping the leaves dry, reducing diseases, ensuring even drying, and guaranteeing uniform growth of the plants in the tray. However, the height of the seedling trays in the current seedling racks is relatively uniform. Different seedling racks need to be replaced according to the different growth stages of the plants, which wastes manpower and resources and can easily affect the survival rate of the plants.

[0003] The existing equipment has a relatively limited range of seedling heights, usually using a pull-out mechanism to adjust the height. However, this pulling-out process can easily damage the seedlings, causing them to be obstructed by the upper seedling tray. The operation is cumbersome and cannot be adapted to seedlings at different growth stages, thus affecting the convenience and practicality of adjusting the seedling height. Utility Model Content

[0004] The purpose of this utility model is to provide a seedling raising frame that facilitates the adjustment of seedling height, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a seedling raising frame for easy adjustment of seedling height, comprising a main body of the seedling raising frame and an adjusting component for adjusting the seedling height. The adjusting component includes movable through holes respectively opened on both sides of the main body to provide activity space, a driving block disposed inside the movable through holes for driving, a carrying frame disposed between two driving blocks, a seedling tray movably connected to the carrying frame, a screw rod passing through the main body for driving, a connecting rod disposed on one side of the driving block for connecting, a hinge frame disposed on one side of multiple driving blocks for connecting, a fixing rod disposed on the other side of the main body for fixing the hinge frame, and a motor disposed at the top of the main body and located at one end of the screw rod for providing power.
