2. Description of the Related Art In artificial cultivation of mushrooms such as enokitake mushrooms and honshimeji mushrooms, bottle cultivation has been popular, in which a culture medium mainly containing sawdust, conuka and the like is filled in a cultivation bottle to carry out mycelial culture. However, after harvesting the mushrooms, it is necessary to scratch the unnecessary medium from the bottle because the bottle is reused, and various medium-raising devices for that purpose have been developed. This general culture-based scraping device is designed so that a plurality of bottles contained in a container are inverted together with the container on a support stand and fixed, and the scraping blade is gradually inserted into the bottle from below the bottle while rotating. The scraping blade cuts the culture medium to drop it below the bottle and discharge it (for example, JP-A-56-109520).

[0003]

However, in the above-mentioned conventional cultivation base scraping device, since the scraping blade is advanced into the bottle while sequentially cutting the surface of the cultivation base by the scraping blade, There is a limit to the speed at which it can enter the bottle, and it takes a long time to scrape it out, resulting in a problem that work efficiency is not improved.
Especially in recent years, the cultivation scale has become large, and an extremely large number of cultivation bottles are circulated and used, and it takes a long time to scrape the culture medium, which is a bottleneck for efficient cultivation. Was needed.

Therefore, the present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a culture medium scraping apparatus capable of efficiently discharging the culture medium in a short time. is there.

[0005]

The present invention has the following constitution in order to achieve the above object. That is, it has a plurality of through holes into which the bottle mouths of the bottles containing the culture medium can be fitted, and the bottle mouths housed in the containers are supported by being inverted while the bottle mouths are fitted into the through holes. A bottle support part, a blade support base disposed below the bottle support part, and a plurality of blade support bases provided on the blade support base so as to be rotatable about their respective axes, corresponding to the through holes of the bottle support base, and the upper end thereof. A scraping blade having a blade portion that bites into the culture medium of the bottle, and the blade portion of the scraping blade enters the culture medium of the bottle so that the blade support and the bottle support portion are contacted with each other a plurality of times. And a drive unit for separating the blade portion, and the blade portion is branched into a plurality of pieces, and the branched portion is bent obliquely upward and extends in the rotation direction of the blade portion, and the tip end portion of the bottle is bent. It is characterized by being bent so as to face slightly inward with respect to the inner wall.

[0006]

The operation will be described with reference to FIGS. Motor 56
Is driven to rotate the scraping blade 58. Further to the support table 24 by operating the crank mechanism 36 vertically moves against the biasing force of the spring 28 (which is also the entire bottle support unit 22

The up-and-down moving table 50 as a support is raised and the scraping blade 58 is inserted into the bottle 14. By raising the vertical movement table 50, the scraping blade 58 enters the medium of the bottle 14. At that time, the blade portion 62 is bent so as to extend obliquely upward and in the rotation direction of the blade portion 62, and the tip end portion is bent so as to face slightly inward with respect to the inner wall of the bottle. As the part 62 rotates, the part 62 pierces the medium in a substantially spiral shape and bites toward the center of the medium. While the scraping blade 58 enters the bottle 14 upward from the mouth of the bottle and rises up to near the bottom of the bottle, the support base 24 is vertically swung many times. Therefore, as shown in FIG. 5, when the support base 24 is moved up and down, the scraping blade 58 pierces the support base 24 so as to bite into the medium when the support base 24 is lowered, and then the support base 24 is raised. Therefore, the culture medium is peeled off, dropped, and discharged. Since this operation is repeated many times until the scraping blade 58 rises up to near the bottom of the bottle 14, the scraping blade 58 spirals up and down relatively to the medium along the inner wall of the bottle 14 in a spiral shape. It rises and scrapes the medium in the bottle 14 efficiently.

As a result, the culture medium is peeled off, dropped, and discharged. Since this operation is repeated many times until the scraping blade 58 rises up to near the bottom of the bottle 14, the scraping blade 58 spirals up and down relatively to the medium along the inner wall of the bottle 14 in a spiral shape. It rises and scrapes the medium in the bottle 14 efficiently. In particular, the cultivated medium after cultivating enokitake mushrooms is hard, and efficient scratching cannot be performed by scratching by cutting the surface of the cultivating blade as in the conventional case, but in this embodiment, the raked blade is pierced into the cultivated medium Therefore, scratching can be performed extremely efficiently. When the scraping of the culture medium is completed as described above, the cylinder 48 is driven to raise the bottle 14 and the container 12 together with the rail 20, and then the bottle 14 and the container 12 on the carry-in station A are pushed by the pusher 18 as described above. Then, it is carried into the scraping station B. The bottle 14 on which the scraping on the scraping station B has been finished is pushed by the next bottle 14 and the container 12, slides down on the rail 57, reaches the rail 58, and is carried into the carry-out station C. It is discharged to the outside by the carry-out device.

The shape of the blade portion 62 is not limited to the above, and may be any shape that allows the blade portion 62 to bite into the culture medium when it is raised and to pull down the culture medium when it is lowered. Also
The support base 24 and the vertical movement base 50 may be moved relative to each other a plurality of times so that the blade portion 62 of the scraping blade 58 enters near the bottom of the bottle 14. Although the present invention has been variously described above with reference to the preferred embodiments, the present invention is not limited to these embodiments, and many modifications can be made without departing from the spirit of the invention. .
