Stackable moisturizing machine transplanting seedling tray

Abstract

A foldable moisturizing mechanical transplanting seedling tray comprises a tray bottom and frames. Leakage holes which are evenly arranged are formed in the tray bottom, reinforcing ribs and a footing frame are arranged on the lower end face of the tray bottom, and flanges are arranged on the frames. The seedling tray is characterized in that pits which are evenly arranged in a vertical and horizontal mode are formed in the tray bottom, convex ribs are arranged between the pits, the leakage holes are formed in intersections of the convex ribs, the upper opening of each leakage hole is large, the lower opening is gradually necked, each leakage hole is shaped like an inverted cone, and big edge coverings are arranged on the outer walls of four corners of the footing frame. Water can be stored in the tray bottom through the pits, the moisturizing effect can be achieved through water storage, and growth of seedlings is benefited; the inverted-cone-shaped leakage holes combine water permeable and water retention functions, a certain number of seedling root systems can penetrate through the inverted-cone-shaped leakage holes, and it is guaranteed that seedling root system growth is more stable; when multiple seedling trays are arranged in an overlapped mode, the footing frame of the previous seedling tray is clamped on the inner wall of the next seedling tray, the thickened big edge coverings on the four corners are matched with the inner walls of the frames in a positioned mode, and overlapping of the seedling trays is stable and reliable.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a stackable seedling raising tray for a moisturizing machine. Background technique [0002] With the continuous development of mechanization in rice cultivation in my country, mechanized transplanting has been gradually realized in rice seedling transplanting. The key to rice machine transplanting is seedling cultivation in seedling trays. The upper surface of the bottom of the existing seedling raising tray is usually a flat design, and the roots are severely damaged by machine transplanting, uneven emergence of seedlings, and slow greening after machine transplanting. Because the seedling tray is shallow, the soil capacity in the tray is small, and the moisture retention capacity is poor, the water in the seedling tray is easy to disperse, and the frequency of watering is high. Traditional rice seedling trays are provided with reinforcing ribs on the lower surface of the bottom of t...

AI Technical Summary

Problems solved by technology

The upper surface of the bottom of the existing seedling tray is usually a flat design, which causes serious damage to the roots and seedlings, uneven emergence of seedlings, and slow greening after machine transplanting.

Because the seedling tray is shallow, the soil capacity in the tray is small, and the moisture retention capacity is poor, the water in the seedling tray is easy to disperse, and the frequency of watering is high.

The traditional rice seedling tray is made with reinforcing ribs on the lower surface of the bottom of the tray, the strength of the whole seedling tray is poor, the compressive capacity is poor, the seedling tray is easily deformed during moving, and the service life is short

When there are multiple overlapping seedling trays, the lower seedling tray has no mechanism for positioning the upper seedling tray, the stacking is unstable and the reliability is poor
