DD276019A1 - PALLET FOR GROWING YOUNG PLANTS - Google Patents

Abstract

The range for the cultivation of young plants serves the admission of Pflaenzlingen, which are introduced in the Einzelkornsaeverfahren or as a Pikierling, and their rearing up to the Umpflanz- or Auspflanzstadium. The shape of the containers for receiving the plants allows a good rooting but also a slight separation of the Pflaenzlinge from the range in different stages of growth. Characteristically, the pallet has containers which have a circular cross-section in each horizontal cross-sectional height, with the diameter progressively increasing from the bottom to the top edge. Openings at the bottom of the containers have a circumferential reinforcement without edges. For machine transport and stabilization, the pallet has a circumferential, uninterrupted bead around the outer rows of containers. Fig. 2

Field of application of the invention

The range for the cultivation of young plants serves for the admission of Pflänzlingen, which are either in the Einzelkornsä verfahren or introduced as Pikierlinij and whose cultivation takes place up to the transplanting stage or lance stage in the pallet. The range is suitable for use in horticulture, especially for farms that produce vegetables and / or ornamental plants.

Characteristic of the known state of the art The prior art is made possible by a variety of designs of culture containers, which are mostly made of plastic,

shown.

Thus, from DE OS 3047646 a Sfimlingselnheit known, which consists of a variety of seedling pots, the

arranged side by side and combined to form a unit. Each pot comprises an ohor frame, which at the same time forms part of the upper side of the seedling unit, and a number of strips projecting downwards from the underside of the frame. These strips converse downwards, forming a tapered pot. The streaks are so stiff that they can be joined without being traversed by tucks, the root clod trapped during the process

Keep seedling growth and during handling and transport of the unit. At the same time they have such an elasticity that they can be bent far enough apart for the root clod

to be able to return to their original position after removal of the root clot.

In particular, by the downwardly open and also slotted on the Soiten plant pots arise considerable Nachtelle, which seems the palette for a mechanized removal of the plants with the root ball unsuitable

to let. Beispielswelse The removal of the root ball is possible only with considerable effort, since in the

Root ball developing roots tend to become in the slot, which is formed by the elastic strips to

pull and out there beyond the edge of the plant pot. With mechanical ejection of the root ball, these roots would hinder the process of sliding the root ball and inevitably damaging the roots is also to be expected, which is unfavorable in terms of plant engineering.

From EP 0254434 a growing range with rectangular pots is known, with two opposite Side surfaces approach towards the plant pot bottom. Foam materials are used as material. , This cultivation range is also unsuitable for the machine removal of the young plants, since lack of ejection openings

would have to be attacked directly to the plant to remove the young plants, which can always be associated with injury to the plant.

Furthermore, the practice has shown that the root bales of young plants from foamed pallets solve relatively poor

let, because the sliding friction is too large.

In DE AS 2269467 and DE AS 2318187 Patten are described, which are made of plastic and both

can be used for the reception of round as well as square pot and substrate plants.

Characteristically, the pallets have a plurality of conical blind holes for receiving the plants, wherein the bottom of the Blind bore has a central opening and at the top of the pallet water supply channels to the individual Saskbchrungen are provided. These pallets are preferably designed to hold the plants in the store for sale. That's it

expedient that also foam material is used as material, as already stated, the plants relatively firmly in the

Palettes sit. However, this contradicts simple machine ejection of the root ball from the pallet.

The aim of the invention is to develop a range for the cultivation of young plants, which allows to receive the seedlings to the Um- or Auspflanzreife and from which the seedlings can be easily removed without damage. The economic goal is thus to optimize the stock density of the young plants while preserving the damage-free removal of the young plants individually from the pallet. In addition, the range should have a broad spectrum of usefulness and should represent the plant-based basis for the fact that the seedlings are suitable both for repotting and for planting.

Presentation of the essence of the invention

The object of the invention is to find an optimal color of the plant container for receiving the root of the plant which ensures both good rooting and easy separation of the seedlings from the pallet at different stages of growth and mechanical ejection, the location of the seedlings both in puttable as audti in auspftonzbaren stages of development is optimized pftanzonbaulich.

! ι η essentially this is achieved in that a preferably rectangular PaIeKe has molded container, which are arranged parallel and linear to each other. The container for receiving the substrate or the plant bale knows on in each Querschnittshtihe a circular en cross section Huf, which increases progres siv from the bottom of the pallet to the top edge. The containers are designed so that duss whose largest diameter and the height dor pallet have a ratio of 1: 0.8 to 1.2. On Bodon the pallet are located in the middle axis arranged openings, which are designed as known as circular holes and characteristically have a umtaufenden reinforced edge without edges, which is pulled up to the inside. The reinforced edge of the bottom opening, in particular, forms a guide for the ejection ram when the plant is ejected mechanically and, at the same time, prevents mechanical damage to the diaphragm.

Between the outer edge of the pallet, which is a maximum of the distance between the center axes rubbing from the center of the outer pot, and dor lußeren Topfreihe bdiindet a complete and continuous circumferential bead. Due to the design of the edge with circumferential bead sowio the spacing between edge, bead and Topfreihen results in a high stability and durability of the range, which is therefore particularly suitable for manual or automatic transport and processing systems. Due to the shape and the smooth plastic surface of the container is advantageously ensured aft that even completely rooted seedlings can be solved easily and without damaging dor roots of the containers. Another important advantage is the good stackability of the pallets in Loerzustand. Due to the smooth surface structures, I am particularly well-suited to use polymeric plastics (PVC, PE) as a starting material for the production of the pallet according to the invention.
