Seedling pot with variable pot volume

Abstract

The invention provides a seedling raising pot tray with variable pot hole sizes and belongs to agricultural machinery. The seedling raising pot tray comprises tetrahedral pot holes, wherein each tetrahedral pot hole is defined by a pot hole bottom wall, a pot hole left side wall, a pot hole right side wall, a pot hole front side wall and a pot hole rear side wall, the pot hole front side wall and the pot hole rear side wall adopt a mutually symmetrically configured involute gear tooth surface shape, notches penetrate through the middles of the pot hole left side wall and the pot hole right side wall from top to bottom, each of the pot hole left side wall and the pot hole right side wall is divided into a front part and a rear part by the corresponding notch, the whole pot hole bottom wall adopts a cambered shape bulged towards the inner side of the pot hole, and a cross section of an upper connecting belt at the upper ends between the tetrahedral pot holes which are adjacent front and back is arc-shaped. The pot hole sizes are increased when pot seedlings are taken from the pot tray, the adhesion force between pot seedling nutrition media and pot hole circumferential walls of the seedling raising pot tray is reduced, and the seedling raising pot tray has the characteristics of novel, reasonable and simple structure, small seedling emergence resistance and convenience, rapidness and reliability in seedling taking, and is particularly suitable for mechanized farming.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a seedling raising pot for transplanting machinery. Background technique [0002] At present, the seedling pots used for transplanting machinery are only tested from the perspective of agronomy, and are not suitable for the characteristics of mechanical transplanting production. Conventional seedling pots have a variety of structures. During seedling cultivation, the nutrient matrix and the wall of the seedling tray produce adhesion, and seed germination and root development cause the volume of the nutrient pot to expand, which increases the force between the vegetative body and the wall of the seedling tray. , Increased the difficulty that pot seedling is taken out from seedling dish to a certain extent. The current methods of taking out the pot seedlings from the pot tray mainly include the ejection type, the pinching of the fingers to pick up the pot body, and the pinching of th...

AI Technical Summary

Problems solved by technology

The speed and quality of taking seedlings in the above three methods are all restricted by the force between the nutrient pot and the wall of the seedling tray. Efficient, convenient and reliable removal of pot seedlings from the seedling tray has become a technical bottleneck restricting dryland machinery to realize fully automatic pot seedling transplanting
