[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cultivating mushrooms such as enoki mushrooms in a bottle and removing the used culture medium remaining in the bottle after cutting the grown mushrooms by blowing compressed air.

[0002]

2. Description of the Related Art In order to cultivate mushrooms such as enoki mushrooms in a bottle, as shown in FIG. 3, a culture medium 1 mixed with rice bran, sawdust and other nutrients as a nutrient source is mixed with a plastic bottle 2.
, And the fungal species 3 is put in the concave portion 1a formed in the culture medium 1, and this is kept in an atmosphere of an appropriate temperature and humidity.
Mushrooms grow and rise from the mouth of the bottle. So cut off the mushrooms, take out the used culture medium remaining in the bottle,
Reuse the bottle.

[0003] The used culture medium remaining in the bottle is not easy to remove because the grown mycelium is firmly fixed in the bottle in a state where the hyphae are firmly bound vertically and horizontally.

[0004] In order to remove the used culture medium, a method has conventionally been used in which the culture medium fixed by blowing compressed air is cracked, and the compressed air is allowed to enter a wide area to break the culture medium into powder.

In this method, as shown in FIG. 4, an air tube 6 is pushed into a bottle 2 held up and down by holding down plates 4 and 5 through a culture medium 1 to near a bottle bottom 2a.
Blow compressed air of 10 kg / cm ² (depending on the type of mushroom). The compressed air enters between the culture mediums to loosen the solidified culture medium, and the spent culture medium which has been rapidly pulverized is discharged from the bottle mouth together with the compressed air.

As shown in FIG. 3, only one concave portion 1a into which the fungi are inserted may be formed, or a plurality of concave portions may be provided as shown in FIG.

[0007]

The mechanism by which the culture medium is rapidly pulverized by blowing compressed air is that the bottle bottom 2a, which is slightly recessed, swells and deforms due to high-pressure compressed air, and the bottle bottom in this portion is deformed. It is thought that a gap is created between the medium and the culture medium, and compressed air suddenly flows in, causing cracks in the culture medium, causing the compressed air to enter the culture medium over a wide area and applying a shock to the culture medium to break the mass. Can be

However, when a plurality of recesses 1a are formed as shown in FIG. 5, for example, the blown compressed air is short-circuited to the recesses 1a as shown in FIG.
Since the compressed air does not pass through, the peripheral portion cannot be cracked, and therefore, this portion 1b cannot be powdered.

[0009]

According to the present invention, an air pipe inserted into a used culture medium and blowing out compressed air from a tip is rotatable by providing a rotating passive part, and a cutter is provided at a part near the tip. And a rotary coupling for sending compressed air to a rotating air pipe is connected to the air pipe to constitute a used culture medium removal device.

[0010]

[Function] A large hole is formed in a used culture medium by inserting an air tube while rotating through a rotating passive unit. When a cutter cuts a hyphae that has grown vertically and horizontally in the used culture medium, it is pulled. In addition, the vibration is applied by the cutter, so that the tightly packed peripheral part of the used culture medium is loosened, and when the compressed air sent through the rotary coupling is blown from the air pipe, the peripheral part is easily collapsed and the bottle mouth is broken. Is discharged from

The air pipe 6 inserted into the bottle 2 sandwiched and held by the holding plates 4 and 5 is divided into a rotating part 6a and a non-rotating part 6b. Is provided with a gear 8 which is a rotation passive part, and an air pipe 6
Is rotated through a gear 8 and an air cylinder 9
Is moved up and down. Reference numeral 10 denotes a connection between the rotating part 6a and the non-rotating part 6b of the air pipe 6, and
A rotary coupling 11 through which the compressed air is passed is connected to a flexible air pipe 12 to supply compressed air to the non-rotating portion 6b. It is desirable that the cutter 7 has a small number of blades protruding radially so that the cutter 7 can be cut while being hooked on the hypha. In FIG. 2, the number of blades is four, but the number of blades may be two, three, or the like in relation to the rotation speed of the rotating portion 6a.

In order to remove the used culture medium from the bottle 2 by the air tube 6 with the cutter 7 attached , the bottle 2 is held down by the holding plates 4 and 5 as shown in FIG. The air tube 6 is raised by the air cylinder 9 while rotating via the gear 8, and the tip of the air tube 6 is pushed into the used culture medium in the bottle 2 .

After passing through the cutter 7 with the rise of the air tube, a cavity 1c is formed in the culture medium. In addition, the rotation of the cutter 7 causes the mycelium to be hooked and pulled on the tip of the cutter, and vibrations due to the rotation are applied, so that the used culture medium around the cavity 1c is finely cracked.

Therefore, when the air cylinder 9 stops pushing up the air cylinder 9 at the position where the tip of the rotating part 6a of the air pipe approaches the bottle bottom 2a and blows out compressed air, the used culture medium near the bottom of the bottle becomes powdered, and The compressed air widely enters through the cracks created by the rotation and vibration of the cutter also into the side part, and the pulverization proceeds rapidly, and the used culture medium is discharged from the mouth of the bottle.

[0016] The rotation center of the air tube 6, if made eccentric with respect to the center of the bottle 2, the effect which with the rotation of the cutter 7 suppress the phenomenon that the bottle 2 is rotated. What
Japanese Patent Application Laid-Open No. 1-16882 discloses a used culture medium removing apparatus.
There is a device described in Japanese Patent Publication No. 10 which rotates.
Move the cutting blade along the inner wall of the bottle to cut the culture medium.
And discharges shavings with compressed air.
Has a different technical idea.

[0017]

[Effect of the Invention] When the air tube is pushed into the used culture medium, the culture medium is turned to form the cavity 1c. Therefore, the culture medium in the side portion of the bottle is cracked by the tension and vibration of the hypha by the cutter 7. The compressed air generated and blown from the air pipe 6 is widely spread in the used culture medium to promote pulverization, and the used culture medium can be quickly discharged from the bottle. Also, cutters with radial blades should be balanced.
It can be rotated at high speed to increase work efficiency.
