Definitions

  • the invention relates to a device for introducing seed grains and young plants into a tubular substrate strand covered with a sheath according to the preamble of claim 1, a method for introducing seeds and young plants into a hose-like substrate strand sheathed with a sheath according to the preamble of claim 24 , a substrate strand according to the preamble of claim 29 and a system for cultivating plants with a substrate strand according to the preamble of claim 30.
  • a device for producing a seed carrier is known from US Pat. No. 3,456,386, which consists essentially of a cylindrical casing that is filled with a plant substrate. A twisted band to which seeds adhere runs in the core area of the plant substrate.
  • the tape with the seeds and the strip-shaped covering are first brought together in a continuous process and then filled with plant substrate in a special device. Then the longitudinal edges of the cover are turned inwards to form a cylindrical endless strand and glued together in the overlapping area. Cylindrical seed carriers of a predetermined length are created by cyclically cutting the endless strand to length.
  • the tape used, with attached seeds is based on a yarn impregnated with glue, which is passed through a storage container with seeds, with the seeds sticking to the yarn.
  • the disadvantage here is that an indefinable number of seeds adheres to each unit of length of the yarn, so the number of seeds per unit of length can only be approximately determined within rough limits.
  • DE 34 30 563 A1 discloses a method and a device for producing plant stumps, in which a plant substrate is spread out from a storage container to form a thin fleece and then formed into a cylindrical substrate endless strand in a strand former. Individual seeds are placed on the endless strand of substrate by means of a feed device and both are wrapped with a strip of wrapping material before the individual plant stumps are created in a cutting device by cutting the wrapped endless strand of substrate to length. The length of time from depositing the seeds to closing the endless strand of substrate with the cover proves to be problematic, since the seeds only lie loosely on the substrate and there is a risk that they will fall off the strand to the side.
  • the object of the invention is to eliminate the disadvantages known from the prior art.
  • Another object of the invention is to make the cultivation of plants as economical as possible.
  • a first aspect of the invention consists in introducing the seeds or young plants, in contrast to the prior art, only after the coating has been applied to or into the plant substrate of the substrate strand.
  • the invention provides the envelope at a predetermined point, that is in constant or to be provided with an opening at a variable distance and subsequently to insert one or more seeds or young plants into the plant substrate through the opening.
  • One of the resulting advantages is that the seedling no longer has to break through the cover as it grows, allowing the plant to develop faster and better.
  • a seed grain or a young plant can be introduced into the substrate strand with the aid of the placement device at a depth adapted to the respective intended use, so that optimal boundary conditions for germination and plant growth are created be created.
  • the opening or depression can be closed with suitable materials such as sand, perlite, vermiculite, hydromulch and the like after the seed has been introduced in order to tailor the nature of the substrate in the immediate vicinity of the seed to the needs of the seed and seedling .
  • a perforating device In order to create an opening in the cover, a perforating device is provided according to the invention, the perforating tool of which can be lowered onto the substrate strand transversely to the axis of the latter, thereby opening the cover.
  • the perforating device can have a stationary guide, along which a tool carrier with a perforating tool, actuated by an actuator, can be moved.
  • the perforating tool It would also be possible for the perforating tool to be arranged on a driven swivel arm which is designed to be pivotable about a stationary swivel bearing on the perforating device, or for the perforating tool to be located at the end of an electronically controlled robot arm which performs the lowering movement.
  • the term "lowerable” is consequently not limited to a linear movement, but includes all possible movements that result in the perforating tool being able to be brought from a position remote from the casing into a position touching or penetrating the casing.
  • the laying device according to the invention with laying tool if the laying tool is designed to be lowered transversely axially onto the substrate strand, and/or the means according to the invention for closing the opening or the depression in the substrate strand and/or the pressing element according to the invention, which can be lowered onto the opening or recess in the substrate strand that is equipped with a seed grain.
  • the cyclically or continuously produced substrate strand is fed to a device for cutting to length and isolating.
  • the continuously manufactured substrate strand is divided into ready-to-use substrate strand sections and at the same time deposited in receiving elements.
  • Suitable receiving elements can be troughs into which the substrate strands are placed, or reels onto which the substrate strands are rolled up.
  • the insertion of the substrate strands into channel-shaped receiving elements and their cutting to length and separation is advantageously carried out with the aid of a control unit which controls the relative movements between a laying head with a laying head end and the receiving elements.
  • a control unit which controls the relative movements between a laying head with a laying head end and the receiving elements.
  • at least the laying head and preferably also the laying head end are arranged in a stationary manner relative to the device, in particular in a linear extension of the conveyor device, and the receiving elements are designed to be displaceable.
  • the laying head end or the laying head end can be designed to be movable together with the laying head for laying down the substrate strand in the receiving units.
  • the recording units can be arranged so as to be stationary with respect to the device or likewise movable. Especially in the case of receiving units with a very large longitudinal extent and/or receiving elements combined to form larger units, this eliminates the need for time-consuming handling of the receiving units during deposition and separation.
  • a substrate strand with a cover, plant substrate and seed grains or plants is arranged in a channel, it being possible for water to be supplied to the channel for irrigation.
  • this system it proves to be an advantage that a large number of substrate strands can be produced and stored independently of the time and location of the channels into which they are later inserted. In this way, the filling of the channels is reduced to simply inserting the substrate strands into the channels.
  • Both the production of the substrate strands and the insertion of the same into the channels are largely automated, which reduces the proportion of manual labor is significantly reduced, thereby speeding up processes enormously. In this way, the process through to the fully planted culture gutter can be designed extremely efficiently and economically.
  • the covering of the substrate strand clearly and permanently separates the area of the plant substrate from the rest of the channel cross-section, which is available as a flow cross-section for the water, for example when watering and draining the channel.
  • the plant substrate can be removed from the gutter simply by removing the substrate strand and, if necessary, recovered. This process is therefore very simple and quick and in turn allows the use of mechanical aids. There are practically no substrate residues left in the gutter, which makes cleaning the gutters considerably easier, if not entirely unnecessary, before they are used again.

Their peripheral surfaces, which can be concave to accommodate the substrate strand 2, are in contact with the casing 4 with sufficient pressure to form a friction fit to transmit a feed force to the substrate strand 2. Driven in this way, the substrate strand 2 moves on guide rollers 8 arranged along the axis 1 , which with their likewise concave peripheral surfaces form a roller conveyor or guide channel running coaxially with the axis 1 .
  • the guide rollers 8 can also be driven with the same direction of rotation.

  • the perforating tool 11 comprises a rotating drill bit 11 ′, which can be lowered onto the substrate strand 2 perpendicular to the axis 1 .
  • the drill 1 T pierces the casing 4 and thus creates an opening 9 in the casing and possibly a depression 12 in the plant substrate 3 if the drill 1 T is lowered further.
  • the size of the opening 9 and, if necessary, the extent of the depression 12 can be determined.
  • the perforating tool 11 can also consist of a punching knife 11", which creates an opening 9 in a short cycle time and in a simple manner.

  • Punching knife 11" can also be part of a wheel or a roller, on whose outer circumference one or more punching knives 11" are arranged, so that openings 9 are produced when the punching knife 11" penetrates the casing 4 as it rolls.
  • a further possibility for creating an opening 9 is to design the perforating tool 11 as a tearing tool 1 T", the free end of which has a pointed or sickle-shaped tearing hook which penetrates into the cover 4 coming from above or the side and when retracting from the substrate strand 2 the cover 4 tears open at certain points, creating an opening 9.
  • a tearing tool according to the invention can also have a plurality of tips which penetrate the cover at close mutual distances and tearing open by subsequently spreading the tips apart.
  • a tearing tool 1 T" is characterized by its robustness with little wear.
  • the perforating tool 11 is formed by a sawing tool 11"", for example by a rotating circular knife, which, in the course of lowering, makes a cut in the casing 4 transversely to the axis 2 and at the same time, due to the curvature of the circular knife Depression in the plant substrate 3 leaves.
  • a sawing tool 11′′′′ is rotating at high speed, a slot-shaped opening 9 with a clean edge and a defined depth is created.
  • Cutting edge 11 and shearbar can be designed like scissors, resulting in a simple slit as opening 9 .
  • cutting edge 11 and counter blade can also run convexly or angularly towards substrate strand 2 in order to produce a flat opening 9 with a depression 12 adjoining underneath. In this way, openings 9 of different geometries can be produced in a short cycle.

  • the holding elements 50 together with the respective substrate strand 2 prevent light from entering a channel 45 falls.
  • growth of algae in a channel 45 is largely prevented and cleaning of a channel 45 is consequently made easier.
  • the channel 45 has a flat channel bottom 47 with upright channel longitudinal walls 48 in accordance with the previously described embodiments, but without an additional holding element.
  • the distance between the longitudinal channel walls 48 is dimensioned such that exactly two substrate strands 2 can be accommodated between the longitudinal channel walls 48 , each of which supports the outer side of a substrate strand 2 .
  • the substrate strands 2 support one another on the inner sides facing one another.
  • support elements 53 are again arranged on the channel bottom 47, each of which carries a substrate strand 2 in two parallel rows above the water level 49 in the channel 45.
  • the distance between the longitudinal walls 48 of the channel can also be dimensioned in such a way that more or fewer substrate strands 2 can be accommodated next to one another in the channel 45 .
  • FIG. 16 relates to an embodiment in which the channel 45 is also intended to accommodate two substrate strands 2.
  • the channel 45 is also intended to accommodate two substrate strands 2.
  • FIG. For this purpose, the area between the bottom 47 of the channel and the two longitudinal walls 48 of the channel is divided by a partition wall 54 .

  • the free longitudinal edges 51 of the holding elements 50 of such a funnel-shaped receptacle maintain a mutual clearance, so that a longitudinal gap is formed.
  • a substrate strand 2 is inserted, it is automatically centered over the longitudinal gap due to the opposing inclinations of the holding elements 50 . In this way, the developing roots of the plants 46 can grow through the longitudinal gap in the direction of the ground 47 and can be supplied with water 49 there.
  • the embodiment shown in FIG. 16 can also have multiple partitions 54, resulting in multiple receptacles for more than two substrate strands 2, or no partition, so that there is only one single partition between the side walls 48 in combination with the holding elements 50 funnel-shaped recording results.
  • the channel longitudinal walls 48 can be guided over the fastening edge of a holding element 50 in order to prevent a substrate strand 2 from unintentionally rolling down from the channel 45 .
  • the embodiment according to FIG. 17 is characterized by a channel 45 with a V-shaped cross section opening upwards.
  • the channel bottom 47 of the channel 45 is angularly formed with two legs, to which the channel longitudinal walls 48 connect.
  • a receptacle with a funnel shape in cross section is created, in which the substrate strand 2 lies and is fixed in position between the longitudinal walls 48 of the channel, which are inclined in opposite directions, or the legs of the channel bottom 47 .
  • the channel 45 is partially filled with water 49, in which the substrate strand 2 is immersed. Additionally or alternatively, an irrigation hose 52 can be inserted into the channel 45 for irrigation, preferably in the gusset between the substrate strand 2 and one or both longitudinal channel walls 48.
