Abstract

The invention has reference to a procedure for selective collection of material and organisms around and on the plants where the material/organisms exist. Some kinds of the material/organisms are collected by exposing the plants to an air current between a blower outlet (7) and a suction hood (5). According to the invention stimuli signals are aimed at the plants in order to influence other kinds of material/organisms to leave the plants and/or to avoid congregating on the plants, so they cannot be exposed to the air current. The invention has also reference to a device for realizing the procedure.

Description

METHOD AND DEVICE FOR SELECTIVELY COLLECTING MATERIAL AND ORGANISMS ON PLANTS

The present invention in a first aspect relates to a method according to the preamble of claim 1 and in a second aspect to a device according to the preamble of claim 6

In connection with plant cultivation there exists a lot of different organisms which in one way or another are dependent on the plants The purpose of this invention is to collect mateπal and organisms from the plant cultivation, especially insects, arthropods and funguses in order to influense the cultivationresult in the desired direction and also to make use of the collected material This procedure creates opportunities for non-poisonous cultivation and use of the plants and the organisms free from chemicals

The collection of organisms on plants by exposing them to compressed air and at the same time sucking them up in a container is previously known, for example by DK 24911

There is a disadvantage with the known device, in that the material and organisms, existing on or around the plants will be injudiciously sucked-up and collected in the container Useful insects like, for example ladybirds, bees and bumble-bees will be sucked up Firstly it is desirable that these are left untouched Secondly the collection of such organisms, means that the collected material is more heterogeneous which makes it more difficult to make use of it for different purposes

The purpose of the present invention is to bring about a procedure and a device of this kind where this disadvantage is set aside and consequently some of the organisms on and around the plants are prevented to be sucked-up in the container

According to the invention this has been attained in that a method of the kind specified in the preamble of claim 1 , includs the special measures specified in this claim^'s characteristic portion and in that a device of the kind specified in the preamble of claim 6 has the special features specified in this claim^'s characteristic portion

Owing to the fact that these signals make some of the organisms leave the plants or prevent them from congregating there, it is possible to avoid that these organisms be sucked-up in the container

According to a preferred embodiment form ofthe invention these signals consist of sound-, light- or scentsignals or combinations of these Through this type of influense some kinds organisms will be frightened away, especially sound- and lightsignals produce this effect Furthermore, by sending out a scentsubstance some kinds of organisms can be made to change residence or to avoid settling down on the plants This allows that the following collection can be made on plants where such kinds of organisms which one don t want to collect are absent due to the scent treatment

It is previousK known, for example by SU 1 685 347. SU 1 777 754, SE 1 16 241 and US 1 478 424 that in collecting organisms from plants, one can expose them to different kinds of influense as for example warmth, scent, sound or light In the known devices and procedures however this influence aims to attract the organisms in order to collect them or in combination with air-sucking improve the effect of the collection They are therefore designed for this purpose and do not allow anv separating effect ln the dependent claims, advantageous embodiments of the invented method and the invented device are mentioned

The invention is more deeply explained by the following detailed description of an embodiment of this with reference to the enclosed figure showing a collection device according to the

The device consists of a blower with varying suction and pressure qualities The compressed air passes the airchannel 9 for distributing the air to the flexible pipes 6 and the especially designed blower outlets 7 The airchannel 9 is equipped with an air pressure regulator The blower outlets are designed in order to aim an air current at the plant and the organism The organisms are instantly, at the same time as the plants start to move, which makes it more difficult for the mateπal and the organisms to cling to the plant and make the transportation possible through the air current to the suction hood 5 The material and organisms are transported through the flex pipes 3 to a suction channel 10, which is equipped with a device for regulation of the suction pressure which leads to a cyclone 12 with container 2 The suction hood 5 can in certain cases be equipped with an elastic screening 15. so the air current more easily can be led in the flow direction In or outside the field between the blowpipe 7 and suction hood 5 the extra fittings 16 are fixed, like equipment for heating - cooling 17 and supply of adding agent 17. scraper 14, brushes 14, sound- and hghtequipment 16 on special holds 13, where they individually can be adjusted to the right height and breadth position The equipment can be fixed on a chassie 1 1, which can be placed on a vehicle such as a tractor or on a selfgoing unit The blower outlets 7 and the hoods 5 are separately fixed to lifting devices 8 and 4 and through flexible tubes 6 and 3 connected with a blower unit 1 whose driving force could be power from a vehicle or a separate motor The brush 14 is best placed hoπzontally and rotating and arranged as vertically and horizontal 1\ adjustible

The field of current air between the blow- and suction outlets is best if it could be varied This could be done by regulating the blow- or suction pressure or both of them Another possibility of regulation could be made bv arranging the outlets sideways and vertically adjustible so that their mutual distance can be adjusted By the adjustment an adaption to the cultivated plants and to the behaviour of the organisms is brought about Warmth or cold added in order to improve the effect can be distributed directly in the field or through blower outlet The effect field can be multiplied with advantage through arrangement of several blow- and suction outlets in order to cover a bigger harvest area The facilities used in order to improve the effect could then be arranged individually for each field or cover more of them The same is true about the signal instruments which influence some of the organisms to depart in order to avoid collection

The collected material from the field, could through the flexible pipes be collected in a container under the cyclon but before the energy source, so that there is a minimal destructive effect on the collected mateπal which makes it possible to use this material This procedure is to be used on plants within the following families among others Umbellate Familv (Umbelhferae), Grass Family (Gramineas), Composite / Daisy Family (Co positae), Wallflower / Crucifer Family (Cruciferse), Mint / Labiate Family (Labiatae), Lily Familv (Lihaceas), Flax Family (Lmaceae), Heath Family (Ericaceae), Goosefoot Familv (Chenopodiaceaε), Rose Family (Rosaceae), Popp\ FamiK (Papaveracea≥), Pea Familv (Legummosae)
