Water is flowing in the water tank 22, and the scraped out bean sprouts are conveyed to a packaging line provided in the downstream direction (in the direction of arrow A). Water tank 22
In the middle part, it assists in transporting bean sprouts and
A plurality of rotating forks 70 are arranged to separate the bean sprout shells from the bean sprouts. This rotating fork 70 is rotated in the same direction as the water flow by a motor (not shown). Therefore, the bean sprouts are conveyed along the water tank 22 toward the packaging line, and at the same time their shells are removed.

Next, the operation of this embodiment will be explained.

The cultivation frame 10 is placed in the cultivation room with the door 12A and the door 12B closed.
Beans are grown inside. When the bean sprouts grow,
An operator moves this cultivation frame 10 from the cultivation room to the scraping position. At this time, the fork 28 is waiting at a position (home position) above the cultivation frame 10 on the front support column 52 side.

The operator opens the doors 12A and 12B 90 degrees, folds them in half at the middle, and tilts the rotating plate 20 forward. Next, when the operator operates the control device 46, the drive motor 62 starts normal rotation and the horizontal movement bracket 50
moves rearward, and the fork 30 integrally moves rearward. The drive motor 62 stops when the fork 30 reaches the rear end of the cultivation frame 10. Subsequently, the drive motor 42 starts normal rotation, the lifting bracket 32 moves downward a predetermined amount, and the tip of the fork 30 is inserted into the upper layer of the bean sprouts in the cultivation frame 10 by a predetermined amount.

In this state, the drive motor 62 starts reverse rotation, the horizontal movement bracket 50 moves forward, and the fork 30 integrally moves forward. Therefore, the bean sprouts in the upper layer of the cultivation frame 10 are conveyed by the forks 30 toward the scraping opening 18 and scraped out from the scraping opening 18.

When the fork 30 reaches the scraping opening 18, the rotation of the drive motor 62 is stopped. The bean sprouts conveyed to the scraping port 18 naturally fall into the water tank 22 because the rotary plate 20 is inclined.

The bean sprouts that have fallen into the water tank 22 are conveyed toward the packaging line by the water flow and the rotating fork 70, and the bean sprouts are separated by the rotating fork 70 during conveyance.

Thereafter, the drive motor 42 is reversely rotated, and the lifting bracket 32 and fork 30 are moved upward by a certain amount. Therefore, the tip of the fork 30 is pulled out from the upper layer of the bean sprouts in the cultivation frame 10. In this state,
The drive motor 62 starts normal rotation, the horizontal movement bracket 50 moves rearward, and the fork 30 is integrally moved to the rear end of the cultivation frame 10. Therefore, the bean sprouts are not collected toward the rear end of the cultivation frame 10. Here, the drive motor 42 is rotated normally again to move the fork support lever 28 downward, and the fork 30 is inserted into the next layer of bean sprouts.
Scrape out the next layer of bean sprouts by rotating step 2.

Repeat the above series of movements and scrape out the opening 18.
All the bean sprouts in the cultivation frame 10 are scraped out.

In this way, the bean sprouts in the cultivation frame 10 are scraped out sequentially from the upper layer, and the drive motor 42 is moved until the tip of the fork 30 reaches the bottom plate 19 of the cultivation frame 10.
When rotated, the drive motor 42 reverses and moves the fork 30 above the cultivation frame 10. Further, the drive motor 62 is reversely rotated to return the fork 30 to the home position, and the scraping operation is completed.

Control of the drive motor 42 and the drive motor 62 is as follows:
By setting the length of the cultivation frame 10 in the front-rear direction, the depth of the cultivation frame 10, and the depth of the fork 30 to be inserted into the upper layer of the bean sprouts by the operator using the operation buttons of the control device 46, the drive motor 42 and the drive motor 6
The number of rotations during each forward and reverse rotation of 2 is determined, and based on this number of rotations, the drive motor 42 and the drive motor 62 are rotated, the fork 30 is moved, and the scraping operation is performed.

Since this embodiment has the above-mentioned configuration, the bean sprouts grown in the cultivation room can be automatically scraped out into the water tank 22, and the operation is safe. Furthermore, since the worker does not come into contact with the bean sprouts, the bean sprouts are not contaminated with dirt and the like, making it sanitary.

Note that, in the above, the width of the fork support member 28 and the width of the cultivation frame 10 are made equal, but the width of the fork support member 28 is made shorter than the width of the cultivation frame 10, and the fork support member 28 is aligned in the width direction of the cultivation frame 10. All the bean sprouts in the cultivation frame 10 may be scraped out by moving the fork 30 up and down, back and forth, and left and right. Further, in the above example, the cultivation frame 1 is
By setting the length and depth of 0 in the front and back direction,
The amount of rearward movement of the fork 30 and the time to stop the scraping operation were determined, but a limit switch was installed at the tip of the fork 30 to detect the rear side wall 15 and base 11 of the cultivation frame 10, and the rear stop position of the fork 30 was determined. Also, the timing of stopping the scraping operation may be detected. In addition, in the above, when moving the fork 30 backward, the fork 30 is moved upward by a slight amount to prevent the fork 30 from coming into contact with the bean sprouts, but if the fork 30 is moved backward without moving upward, Alternatively, the fork support lever 28 may be rotated about a horizontal axis so that the fork 30 does not come into contact with the bean sprouts.

[Effect of idea]

Since the present invention has the above configuration, it has an excellent effect of being able to automatically scrape out plants such as bean sprouts grown in the cultivation room.
