Description

Multi-stage cultivation stand equipped with an elevating work platform {MULTISTAGE CULTIVATION SHELF HAVING A LIFTING TYPE WALK-PLATE}

The present invention relates to a multi-stage cultivation table with an elevating work platform, and more particularly, a series of cultivation management operations for managing growing plants as well as loading the cultivation bed to the loading shelf arranged on each floor through the adjustment of the working position. It relates to a multi-stage cultivation table equipped with an elevating working platform for easier operation.

Until now, plant cultivation (plant husbandry / crop cultivation) has been carried out in a natural environment, so the time, period and place of production are also limited to the soil. Therefore, continuous production was not possible throughout the year, and the supply and demand was not constant due to the high frequency of accidents.

Moreover, damage to crops due to recent global warming, climate change, environmental pollution, etc. has become more and more serious, and the crop production volume is affected by successive occurrences of abnormal climate phenomena such as lack of sunlight, frequent torrential rains, and the progression of other typhoons both domestically and globally. The necessity of introducing plant factories is increasing in order to solve the unbalanced agricultural economy due to a decrease and soaring prices.

A plant factory is an agricultural system that enables planned production by artificially controlling the growth environment of plants indoors. Plant growth environment such as light intensity, temperature/humidity, carbon dioxide concentration, water, and culture solution within a certain facility. It refers to a system that artificially controls crops to grow crops.

In particular, the achievement of the above-described indoor cultivation system is not affected by external environments such as climate change and extreme weather, as well as multi-stage cultivation using artificial lighting in a small area, so a large amount of crops per unit area (hereinafter referred to as "plants") It is becoming an essential element for future agriculture in a situation where environmental problems become more serious as it can be grown.

Here, the multi-bed cultivation, which maximizes space utilization and improves management efficiency of cultivated plants, is carried out by loading multiple cultivation beds (vegetation trays, vegetation mats, etc.) in multiple layers for the purpose of efficient use of limited space. For this, a multi-stage (multi-layered) plant growing zone is required.

In this regard, Korean Registered Patent No. 10-1246782 (Name of invention: Plant cultivation device for expanding cultivation space), Korean Patent No. 10-1649337 (Name of invention: Prefabricated structure for plant cultivation system), Korean Patent No. 10-1141777 (name of the invention: rotary multi-stage hanger device and survival chamber system having the same), Korean Patent No. 10-1452284 (name of the invention: plant cultivation device using artificial light), etc. A number of prior art based on ideas have been disclosed.

By the way, all of the above-described prior art simply constitute a multi-stage loading structure, and most of them are manufactured somewhat higher than the height of a person for loading a large number of cultivation beds, so it is difficult to put the cultivation beds on the lower and middle layers of the shelf (stacking bed). It is not a problem, but the work of placing the cultivation bed on the upper shelf higher than the height of the worker is inevitably difficult and cumbersome.

Moreover, in the case of crops growing in a cultivation bed that is higher than the operator's height, that is, a position slightly higher than the operator's eye level, on the upper shelf, occasional cultivation management such as giving fertilizer or checking the growth. There has been a problem that is not easy.

In the end, research and development of a plant cultivation stand is urgently required to facilitate a series of operations for cultivation management of cultivated plants and to enable height adjustment of the working position while on board the operator.

It is a cultivation bed loaded on each floor of the main body.

The operation of the multi-stage cultivation table (A) having an elevating working footrest according to the present invention having the above configuration will be described in detail.

First, the multi-stage cultivation material (A) provided with an elevating working platform of the present invention is limited in a plant factory, an agricultural system capable of planned production by artificially controlling the growth environment of plants indoors. In consideration of the efficient use of space, multiple cultivation beds (or vegetation trays, vegetation mats) are stacked in multiple layers to maximize space utilization and increase the management efficiency of cultivated plants, which is installed and used for the multi-bed cultivation. As such, it is possible to maximize management efficiency as well as space utilization described above by loading a plurality of cultivation beds p on each layer of the cultivation main body 1.

In particular, the work of placing the above-described cultivation bed (p) on the loading shelf (12) arranged at a higher position than the worker's lodge due to the multi-layered shelf-type structure and cultivation plants growing from the cultivation bed (p) so loaded. The management of the bar is not easy, which causes the lifting operation of the working scaffold 2, so that the working position of the worker on the working scaffold 2 is moved up and down, as shown in FIGS. 7A to 7C. By adjusting the height of the working scaffold (2), as described above, the cultivation bed (p) is placed on the loading shelf (12) arranged at a high position, and the management of the cultivated plants growing in the cultivation bed (p) is Make it easy to work for.

Specifically, a user manipulates a separate controller (not shown) for the operation of the driving device 3 so that power is supplied to the driving device 3, and accordingly, the driving motor 31 of the driving device 3 ) Is rotated by the rotational power generated by rotational drive, and the power is transmitted to the linkage shaft 36 through the belt and pulley 34, and the rotation of the bevel gear 35 As the rotational force of the linking shaft 36 is transmitted to and rotated by the screw shaft 32 vertically mounted in front of the cultivation base body 1, the working scaffold 2 assembled to the screw shaft 32 ) Of the lifting block 23 to rise or fall along the spiral of the screw shaft 32, the scaffolding body 21 linked to the lifting block 23 is moved up and down together with the working scaffold 2 ) And the height adjustment of the working position accordingly.

In addition, in the process as described above, in a predetermined section in which the first ascending and final descending of the working scaffold 2 is made, the scaffolding body 21 can be unfolded or folded by the folding means 4. In accordance with the same process as in FIGS. 5A to 5C, when the initial ascending movement of the lifting block 23 starts, the link pinion 43 geared to the rack 41 makes a corresponding rotation. A gear meshing rotation is achieved, and the driving pinion 42 geared to the link pinion 43 also performs a gear meshing rotation that makes a corresponding rotation, so that the scaffolding body 21 is unfolded in a horizontal state so that the operator can climb. It becomes possible.

In addition, as described above, when the scaffolding body 21 is unfolded in a horizontal state, a considerable load is applied to the working scaffolding 2 by the operator rising, and thereby the scaffolding body 21 sags downward. According to the same process as in FIGS. 6A and 6B, the support 25 may be sufficiently solved by supporting and supporting the scaffolding body 21.

And, when the final lowering movement of the lifting block 23 is made, by the operation of the folding means 4 opposite to the above-described operation by folding the footrest body 21 in a vertical state, the above-described operation It is possible to prevent the footrest 2 from taking up space unnecessarily.
