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

Embodiment Construction

[0016] The following describes the creative implementation of the present invention in detail with reference to the accompanying drawings. A pot hole for raising seedlings with a variable volume comprises a tetrahedral pot hole formed by a bottom wall 1, left and right side walls 4 of the pot hole, and front and rear side walls 2 of the pot hole. Symmetrically arranged involute tooth surface, in the middle part of the pot hole on the right side wall 4, there is a gap 5 penetrating from top to bottom, and the gap 5 separates the left and right side walls 4 of the pot cavity into the front , The latter two parts, the bottom wall 1 of the pot hole is a curved surface protruding to the inside of the pot hole as a whole, and the upper connecting belt 3 at the upper end between the front and rear adjacent tetrahedral pot holes is curved in cross section .

[0017] When raising seedlings, the seedling pots are laid flat, which is the same as the conventional pot seedlings. When transp...

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 agronomic point of view, and are not suitable for the production characteristics of mechanical transplanting. Conventional seedling pots have various structures. The nutrient substrate and the wall of the seedling plate will have adhesion force during seedlings, and the seed germination and root development will cause the volume of the nutrient pot to expand, which increases the force between the vegetative body and the wall of the seedling tray. , To a certain extent, increase the difficulty of taking out the pot seedlings from the seedling tray. The current methods of taking out the pot seedlings from the pot mainly include the ejection type, the finger-clamping bowl type, and the finger-clamping method to take the se...
