Plant cultivation apparatus

Abstract

The purpose of the present invention is to provide a plant cultivation apparatus with which increased equipment complexity is limited and adverse effects on constituent members are prevented while the apparatus is also capable of automatically sprinkling leaf surfaces with a chosen timing and number of repetitions and capable of improving production efficiency. The apparatus is provided with: multiple cultivation shelves (121) for housing multiple cultivation trays (110); a transport means (130) for conveying the cultivation trays (110); and a sprinkling means (140) for sprinkling a sprinkling liquid on the plant leaf surfaces. The sprinkling means is disposed on the cultivation tray (110) conveyance path or at the conveyance destination and is provided with: an isolating member (141) for forming a partitioned space; and sprinkling nozzles (143) for sprinkling the sprinkling liquid toward the interior of the space.

Description

technical field [0001] The present invention relates to a plant cultivation device comprising: a cultivation pot for holding plants; a plurality of cultivation shelves for accommodating the cultivation pots; a transfer unit for transporting the cultivation pots; The dispersing unit using a liquid, for example, relates to a plant cultivation device used in an automated plant factory for plant cultivation in an artificial environment. Background technique [0002] In the past, following plant cultivating device (for example, refer to patent document 1 etc.) is known, and it is equipped with: the cultivation pot that keeps plant; A plurality of cultivation compartments that accommodate cultivation pot; A watering mechanism that automatically supplies cultivation liquid containing nutrients, etc. [0003] The plant cultivation device known in this patent document 1 (Japanese Patent Application Laid-Open No. 2000-209970 ) does not consider automatic spraying of pesticides, growt...

AI Technical Summary

Problems solved by technology

[0014] In a known plant cultivating device like Patent Document 2, it is necessary to arrange a plurality of spreading units, so there is a problem that equipment such as piping becomes complicated.

[0015] In addition, since the liquid scattered over the entire plant cultivation device will scatter, it may cause adverse effects such as staining or corrosion of the constituent members of each part of the plant cultivation device.

[0016] In addition, since the liquid is sprayed as watering, when spraying growth-promoting ingredients, pesticides, etc. on the leaf surface, these ingredients have to be mixed in the usual watering water, so there are ingredients, pesticides, etc. that cannot be used to promote growth at different times. dispersal and watering problems

[0017] In order to disperse and water the growth-promoting ingredients and pesticides on the leaf surface at any independent time, it is also conceivable to reconfigure the same dispersal unit on another system. A known plant cultivation device with a watering unit such as Document 1 is equipped with a spraying unit like Patent Document 2 for spraying growth-promoting ingredients, pesticides, etc., but it is unavoidable to complicate equipment such as piping or cause damage to structural members. bad influence problem

[0018] In a known plant cultivating device such as Patent Document 3, since the cultivation pot is transported by the jointless transport device, it is necessary to synchronize the spraying time of the growth-promoting components, pesticides, etc. on the leaf surface with watering or work, etc. In addition, in order to only increase the number of times of spreading, it is necessary to add spreading units at other positions on the path, and there is a problem that it is difficult to perform spreading at an arbitrary time and number of times different from other processes

[0019] In addition, such a structure cannot be applied to known plant cultivation devices like Patent Document 1 or Patent Document 2.
