Description

[Detailed description of the device] [Industrial applications]

  The present invention is an artificial cultivation of mushrooms that grows artificially-grown trees using a bag. When picking up a tree, it can be easily crushed and taken out without damaging the tree. A culture bag for mushrooms.

[0002]

[Prior art]

  Generally, artificially grown trees used for artificially cultivating mushrooms such as shiitake mushrooms are Fill the packaging bag with sawdust made of wood such as chestnuts and chestnuts, and inoculate in a state of weak pressure. After that, the upper opening of this packaging bag is closed and the temperature and humidity By culturing the bacteria under conditions, the mycelium spreads on the sawdust in the packaging bag and the artificial wood Is making.   Then, after the hyphae have spread, the packaging bag is crushed, the temperature of the wood is changed, and the wood is immersed in water. Let me induce mushrooms.

[0003]   Conventionally, the sack of this packaging bag is made of artificial wood because it has a rough dimension. It is difficult to operate, and this bag-breaking work is performed manually using a cutter knife. Was there.   However, as the scale of production increases, this process becomes a bottleneck and automation In order to achieve this, for example, a bag breaking device according to Japanese Patent Laid-Open No. 2-171119 has appeared. .

[0004]   This device accommodates an artificial tree and straightens a packaging bag whose upper end side, which is an opening, is closed. A conveying means for conveying in an upright state, and engaging with the bottom of the packaging bag conveyed by the conveying means, A pair of bag bottom holding claws for holding the bottom of the packaging bag, and a pair of bag bottom holding claws provided in the middle of the conveying means. Opening means for opening the upper end side of the packaging bag, and a downstream side of the opening means. Is provided in the middle of the carrying means and extends upward and downward on the side surface of the packaging bag. A plurality of cutters for making a plurality of cuts, and a side surface of the packaging bag by each cutter. With only the bag bottom gripping claw in the state where the cut is made, move only the packaging bag to the lower side of the conveying means. And pull out the artificial wood from the opening on the top side of the packaging bag. The packaging bag is removed.

[Problems to be solved by the device]

  However, in the above-mentioned conventional technique, the bottom portion of the packaging bag is grasped by each bag bottom grasping claw, and Each bag bottom gripping claw pulls only the packing bag below the conveying means, Is forcibly pulled out from the artificial wood through the opening on the top side. There is such a drawback.   That is, when the upper end side of the packaging bag is opened by the opening means, this opening side is in the radial direction. Since it tends to bend inward and reduce the diameter, use a cutter on each side of the packaging bag. When making multiple cuts, extend these cuts to the location of the top opening of the packaging bag. It cannot be lengthened, and the packaging bag is pulled out from the artificial wood through this upper opening. Occasionally, the upper end opening of the packaging bag makes frictional contact with the upper end of the artificially picked tree, etc. It has the drawback of damaging and damaging trees.   Also, in order to deepen the depth of each cut to be put on the side of the packaging bag with each cutter, If you make the protruding size of the cutter large, make each cut in the opening on the top side of the packaging bag. It becomes possible. However, in this case, the tip of each cutter is on the side of the packaging bag. To penetrate deeper into the outer surface of the artificially-grown tree, and cut relatively deeply into the outer surface of the artificially-grown tree. Eyes get injured, each cutter damages the artificial tree, and the artificial tree spreads. There is a drawback that the mycelium that was made to be damaged.

[0006]   Furthermore, because the automated device is designed with the shape of the packaging bag unchanged, the device does not work. However, it is complicated and expensive.   Also, as a bag breaking means, a cutter is used both in the above-mentioned manual operation and in the bag breaking device. As a result, the fundamental problem of causing damage to the wood has not been solved.

[0007]   The present invention has been made in view of the above-mentioned problems of the prior art, and is manually or automatically performed. When breaking a bag with a chemical device, it can be broken without using a blade, so it is not damaged It is an object of the present invention to provide a culture bag for mushrooms, which can surely prevent damage and damage.

[0008]

[Means for Solving the Problems]

  The above-mentioned object is a bag for cultivating mushrooms in which a bag is filled with a medium to generate mushrooms. A pair of notches is formed at a position opposite to each other in the opening. This is achieved by using a mushroom culture bag.   In addition, if a bag made of gusset fold is used as the culture bag for mushrooms, the shape is stable and cylindrical. You can easily make a wood of wood.   In addition, the bag can be easily broken by simply inserting a V or I shape into the notch shape of the bag. it can.

[0009]

[Action]

  As described above, the mushroom culture bag according to the present invention is less common in the opening facing position. Since the pair of notches are engraved, when tearing the bag, set this notch in the middle and pull it to the left and right. You can easily tear the bag along the notch line of the notch with a light force just by stretching. .   Therefore, if you cultivate mushrooms in this bag, use a cutter when breaking the bag. You can easily break the bag.   Furthermore, in the bag breaking device using this bag, the bag breaking device is designed and implemented with a simple mechanism. Can be revealed.
