Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a lifting unit of a mushroom cultivation apparatus,

The present invention relates to a lifting unit, and more particularly, to a lifting unit of a mushroom growing apparatus capable of circulating layers of trays containing mushroom seeds.

It is difficult to artificially cultivate the parasitic parasites that form mycorrhiza in the roots of the trees. However, it is possible to cultivate the mushrooms which are parasitic on dead trees and organic matter by culture.

Conventionally, a mushroom cultivation apparatus generally uses a method of circulating a tray along a certain route by coupling a chain and a motor, and this method requires a large installation space because of a large area of the facility, There is a problem in that the chains are gradually clogged due to the weight of the trays and the like, which necessitates continuous maintenance.

Accordingly, in recent years, a large amount of mushroom has been grown in a narrow space by arranging a mushroom regeneration plate (hereinafter, referred to as a 'tray') in a growth chamber. In order to achieve uniformity of quality by keeping the growth environment constant, A mushroom growing apparatus for circulating the tray up and down along the path is used.

In this case, the upper and lower circulation type mushroom cultivation apparatus has a circulation path in which the trays moved upward one by one to the uppermost layer come back to the lowest level again. In this case, since a plurality of trays must rise together at the same time, There is a problem that a large amount of driving force such as electric power is required.

Further, when the tray is lifted or lowered, there is a problem that a tray that has been waiting for the next turn is pushed by a rising or falling path due to vibration or an external impact, resulting in a failure due to collision.

Further, when the tray moves up and down a section of the distance between the uppermost layer and the lowermost layer by the operation of the cylinder, a large capacity cylinder is required and the facility cost is increased. In the case of applying a small capacity cylinder There is a problem that the operation accuracy is deteriorated because a separate device capable of compensating for the expansion and contraction distance of the cylinder is required. In the case of a malfunction, there is a problem that a failure occurs due to collision with other parts after passing a predetermined position.

In addition, there is a problem in that the tray being lifted or lowered falls from the lifting and lowering stand due to the vibration generated when the tray is lifted or is impacted from the outside, or falls into the predetermined horizontal movement path after the lifting and lowering.

It is an object of the present invention to provide an elevating unit of a mushroom cultivation apparatus which enables circular movement of a tray containing mushroom seeds.

Another object of the present invention is to provide an elevating unit of a mushroom cultivation apparatus capable of reducing driving power such as electric power required for operation and reducing operation cost.

13 to 22 are schematic views showing a tray circulation path of a mushroom cultivation apparatus including an elevation unit according to an embodiment of the present invention.

Hereinafter, the operation of the mushroom cultivation apparatus 100 including the elevation unit according to an embodiment of the present invention will be described with reference to FIGS. Although the drawing shows an example of the mushroom cultivation apparatus 100 in which the conveying rail 300 is formed in eight upper and lower layers and the tray 400 is arranged in 10 rows (11 rows in the lowermost layer) in one layer, It is to be noted in advance that the transferring rail 300 can be formed in the frame 200 as an even-numbered layer, and the number of the trays 400 disposed in one layer can be appropriately selected as necessary.

First, as shown in FIG. 13, a raising rail 750 on which a tray 400 is placed is positioned on the left side of a conveyance rail 300 of the lowest layer (one layer). The first descending rail 612 is located on the left side of the conveying rail 300 of the third, fifth and seventh layers in a state where the tray 400 is seated. The second descending rail 622 is located on the tray 400, 3 < th >, 5 < th >, and 7 < th >

Thereafter, by the operation of the lifting motor 740, the conveyor belt 730 moves along the circulating path between the drive pulley 710 and the driven pulley 720. At this time, the raising rail 750 coupled to one side of the conveyor belt 730 is raised together with the conveyor belt 730 by the engaging portion 755 and the engaging member 756 so that the uppermost layer 8) on the left side of the conveying rail 300.

15, the operation of the first elevating cylinder 613 causes the first lowering frame 611 to descend and the first lowering rail 612 to descend one layer at a time. That is, the first lowering rail 612 is positioned on the left side of the conveying rail 300 of the second, fourth, and sixth layers.

Thereafter, as shown in Fig. 16, the engaging member 520 moves to the left with the conveying frame 510 by the operation of the conveying motor 531. [ The locking protrusion 521 is moved away from the tray 400 and the locking member 520 of the even number layer is rotated by the operation of the first rotation cylinder 541 after the completion of the movement, 521).

17, by the operation of the second elevating cylinder 623, the second lowering frame 621 is raised and the second lowering rail 622 is raised one layer by one layer. At this time, the second descending rail 622 is positioned on the right side of the conveying rail 300 of the even-numbered layer.

Next, the transfer frame 510 is moved to the right by the operation of the transfer motor 531. At this time, the even-numbered layer tray 400 in which the latching protrusion 521 of the latching member 520 is hooked, And moves to the right as shown in Fig. At this time, the tray 400 of the odd-numbered layers does not move because the latching protrusion 521 is not hooked, and the tray 400 positioned at the rightmost side of the conveyance rail 300 of the even-numbered layer is moved to the second falling rail 622, respectively.

Thereafter, the second lowering frame 621 is lowered by the operation of the second lifting cylinder 623, and the second lowering rail 622 descends downward one by one as shown in Fig. That is, the second descending rail 622 is located on the right side of the conveying rail 300 of the odd-numbered layer. At this time, the latching member 520 of the even-number layer is rotated by the operation of the first rotating cylinder 541, and the latching projection hanging on the left side of the even-numbered layer tray 400 is released from the tray 400. On the other hand, by the operation of the second rotating cylinder 542, the locking member 520 of the odd number layer rotates, and the locking projection 521 is caught on the right side of the tray 400.

Then, as shown in FIG. 20, the elevating rail 750 located on the 8th floor descends to the one floor, and the first descending rail 612 located on the 2nd, 4th, And is positioned on the left side of the conveying rail 300 of the third, fifth, and seventh layers as shown in FIG.

The tray 400 of the odd number layer with the engaging protrusion 521 of the engaging member 520 is engaged with the engaging protrusion 521 by the movement of the conveying motor 531 And moves to the left as shown in Fig. At this time, the even-numbered tray 400 does not move because the locking protrusion 521 is not hooked, and the tray 400 located at the leftmost position of the conveying rail 300 of the third, fifth, And the tray 400 located at the leftmost side of the one-layer conveying rail 300 enters the rising rail 750. The first rail 612 is located at the left side of the conveying rail 300,

Thereafter, the raising of the raising rail 750, the descent of the first lowering rail 612, the raising of the second lowering rail 622, the movement of the even-numbered layer tray 400 to the right, the movement of the second lowering rail 622 The trays 400 of the respective layers repeatedly move along the predetermined path to the inside of the frame 200 while repeating the descent, the descent of the ascending rail 750, the ascending of the first descending rail 612, .

As described above, according to the elevator unit of the mushroom cultivation apparatus according to the embodiment of the present invention, the trays can be circulated along the multi-layered path, and the driving force required for tray circulation can be reduced.
