Description

[Technical Field]

[0001] The present invention relates to a shiitake mushroom harvesting device and a shiitake mushroom harvesting method, and more particularly to a technique for efficiently harvesting high-quality shiitake mushrooms cultivated in culture bottles. [Background technology]

[0002] Conventionally, mushrooms such as shiitake mushrooms have been cultivated by various methods. The cultivation method using culture bottles has become widespread in recent years because it is easier to manage than other methods. The method using a culture bottle involves filling a culture bottle with a mushroom medium, planting a seed culture to grow mushrooms, and cutting and harvesting the grown mushrooms from the bottle. During cultivation, mushrooms can be managed by culture bottle, making management easy. However, when harvesting, mushrooms must be cut for each culture bottle, which is time-consuming. Also, when cutting by machine, mushrooms with bent stems cannot be cut completely, and some mushrooms are missed. Therefore, there was a need for technology that would reduce the amount of mushrooms left behind, even when harvesting by machine.

[0003] Various techniques have been proposed in this field, including a method of harvesting mushrooms artificially cultivated in culture bottles by cutting them near the bottle opening (see Patent Document 1), which is a well-known technique. More specifically, the method for harvesting mushrooms is described in which multiple culture bottles are held down by a bottle holding mechanism, tilted at an angle, and the cutter and collection chute are raised diagonally while moving back and forth from left to right, and the mushrooms are cut sequentially from bottom to top near the bottle mouth. However, depending on the condition of the mushrooms, the mushrooms around the bottle may hang down from the bottle mouth, which may leave some behind, so this method does not solve the problem. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 3-94614 Summary of the Invention [Problem to be solved by the invention]

[0005] In view of the problem that mushrooms grown in culture bottles cannot be harvested efficiently, the present invention aims to provide a shiitake mushroom harvesting device that can harvest mushrooms such as shiitake mushrooms grown in culture bottles in a short time without missing any of the grown mushrooms. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention provides a harvesting device for harvesting shiitake mushrooms cultivated in culture medium in culture bottles, which comprises a container unit that holds a container unit, a box-shaped container with an open top and multiple culture bottles, with a bottle pressing section that presses the sides of the culture bottles and a container holding section that holds the protrusions on the sides of the container; an inverting section that inverts the container unit held by the container unit holding section; a cutting section that slides a cutter from one end edge of the inverted container unit toward the opposite end edge along the opening of the culture bottle to cut the shiitake mushrooms; and a collection section that receives the shiitake mushrooms cut by the cutting section in a collection tray.

[0007] In addition, the present invention employs a means in which the bottle holding portion has a plurality of rod-shaped bodies, each of which is positioned so as to contact the shoulders near both openings of adjacent culture bottles, and the rod-shaped bodies are used to restrict the movement of the culture bottles in a direction away from the container.

[0008] Furthermore, the present invention employs a means in which the number of cutters in the cutting section corresponds to the number of culture bottles lined up on one end edge of the container unit, and the angle of the cutter blade is inclined at 8 to 15 degrees toward the other end edge of the container unit relative to the one end edge of the container unit.

[0009] Furthermore, in the present invention, the moving speed of the cutter in the cutting section is 、5The speed is measured at a speed between 15cm / s and 15cm / s.

[0010] Furthermore, the present invention provides a means for vibrating the culture bottle when the inversion section is completed, so that the culture medium in the culture bottle is displaced vertically toward the mouth of the culture bottle.

[0011] Furthermore, the present invention employs a means in which, when the collection section cuts the shiitake mushrooms, the collection tray is lifted to the vicinity of the cutting position, and the insole placed on the collection tray is pushed up by a push-up section inserted through a gap in the bottom surface of the collection tray, thereby lifting at least a part of the insole from the collection tray.

[0012] Furthermore, the present invention provides a harvesting method for harvesting shiitake mushrooms cultivated in culture media in culture bottles, which comprises the following steps: a holding step in which a container unit containing multiple culture bottles is held in a box-shaped container with an open top by a bottle pressing section that presses the sides of the culture bottles and a container holding section that holds the protrusions on the sides of the container; an inverting step in which the container unit held by the container unit holding section is turned upside down; a cutting step in which a cutter is slid from one end edge of the inverted container unit to the other along the opening of the culture bottle to cut the shiitake mushrooms; and a recovery step in which the shiitake mushrooms cut in the cutting step are received in a recovery tray. [Effects of the Invention]

[0013] According to the shiitake mushroom harvesting device and shiitake mushroom harvesting method of the present invention, when cultivating mushrooms such as shiitake mushrooms in culture bottles, the grown mushrooms can be harvested in a short time without being missed, thereby improving harvesting efficiency and benefiting the user.

[0018] The shiitake mushroom harvesting device 1 is a device that cuts and harvests mushrooms such as shiitake mushrooms that have been grown in a culture bottle 20 that is inverted upside down. The shiitake mushroom harvesting device 1 is composed of a container unit holding section 30, a retracting section 40, an inverting section 50, a cutting section 60, a recovery section 70, a supply side conveyor 80 and a take-up side conveyor 81, and is used to harvest shiitake mushrooms 24 from the container unit 10. The container unit 10 consists of a container 11 and a culture bottle 20. The culture bottle 20 is filled with a culture medium 21, and the spores of the planted shiitake mushrooms 24 grow therein, with the grown shiitake mushrooms 24 protruding from the opening 22 (FIG. 4(a)). Near the opening 22 of the culture bottle 20, there is a shoulder 23 that is slightly thinner than the overall width of the culture bottle 20, and by pressing the shoulder 23 from the top of the protrusion 12, it is possible to restrict the upward movement of the culture bottle 20. The container 11 is a case for storing multiple culture bottles 20. It is dish-shaped and has multiple openings on the bottom and sides. A protrusion 12 of uniform width is formed around the circumference of the container 11 (Fig. 2). In this embodiment, 16 culture bottles 20 are arranged in a container 11 in four rows and four columns.

[0019] The shiitake mushroom harvesting device 1 is a device that, as a whole, smoothly harvests shiitake mushrooms 24 from multiple container units 10 using an assembly line conveyor. The conveyor consists of a supply conveyor 80 that carries the container units 10 and a take-up conveyor 81 that carries the collection trays 90. Both conveyor rollers 82 are arranged at equal intervals, allowing the container units 10 to flow smoothly. The supply conveyor 80 is divided in the middle of the flow, with the upstream side also referred to as the supply inlet conveyor and the downstream side as the supply outlet conveyor. A lead-in section 40 is provided between the two conveyors. The take-up conveyor 81 is divided in the middle of the flow, with the upstream side also referred to as the take-up entrance conveyor and the downstream side as the take-up exit conveyor. A cutting section 60 and a recovery section 70 are provided between the two conveyors. A reversing section 50 is provided at a position bridging the lead-in section 40 and the cut section 60.

[0020] The container unit holding part 30 holds the container unit 10 and is fixed to the rotating arm part 52 of the inverting part 50. In this embodiment, the culture bottle 20 is turned upside down, so it is necessary to hold the container 11 and the culture bottle 20 so that the culture bottle 20 does not fall out of the container unit 10. The container unit holding section 30 consists of a bottle pressing section 31 and a container holding section 35. The bottle pressing section 31 consists of a rectangular parallelepiped with a width approximately equal to that of the container 11 and multiple rod-shaped bodies 32 extending from the side of the rectangular parallelepiped (Fig. 2). The spacing between the rod-shaped bodies 32 is roughly the same as the thickness of the culture bottles 20. Each rod-shaped body 32 is positioned so as to contact the shoulder 23, which is the side face closest to the opening 22 of the adjacent culture bottle 20, and the rod-shaped bodies 32 restrict movement of the culture bottles 20 in a direction away from the container 11 (Fig. 2). In other words, the culture bottles 20 are skewered and fixed by the rod-shaped bodies 32. Container holding parts 35 are provided on both ends of the bottle pressing part 31 of the container unit holding part 30. The container holding parts 35 are parts that support the protrusions 12 of the container 11, and are provided as support parts when the container 11 is rotated in conjunction with the rotation of the container unit holding part 30. The container holding parts 35 are structured to be hung over at least the lower ends of the protrusions 12 of the container 11, and when the container unit holding part 30 rotates, they lift the container 11 upward or lower it downward. In this embodiment, the specific form of the container holding portion 35 is shown as a U-shaped structure that grips the protrusion 12 of the container 11 (Figure 2), and by gripping the container 11 from the side, it is possible to restrict the vertical movement of the container 11.However, as long as it is a form that can support the lower end of the protrusion 12, it is not limited to a U-shaped structure, and it may be, for example, an L-shaped structure that does not have a part that supports the upper end of the protrusion 12, or a rod-shaped body that simply supports the lower end only.

[0021] As shown in FIG. 2(a), the container unit 10 is slid laterally toward the container unit holding portion 30. The tip 33 of the rod-shaped body 32 is tapered. This allows the container unit holding part 30 to be smoothly passed around the shoulder 23 of the culture bottle 20. Furthermore, the protrusion groove 36 of the container holding part 35 is provided with a guide part 37 for smoothly inserting the protrusion 12. The end of the guide part 37 is provided with an inclined part 38, which allows the container holding part 35 to be fixed along the protrusion 12 even if there is a misalignment between the container unit holding part 30 and the container unit 10.

[0022] As shown in Figure 2(b), the container unit 10 is held by the container unit holding part 30, and the bottle pressing part 31 restricts the movement of the culture bottle 20 relative to the container 11, so that even if the container unit 10 is moved or inverted, the container 11 and culture bottle 20 can be held without falling.

[0023] The retraction section 40, also called the retraction pusher section, is the section that retracts the container units 10 that have flowed along the supply side conveyor 80 into the inversion section 50, and receives the container units 10 that have completed harvesting from the inversion section 50. The retracting section 40 is mainly composed of a retracting table 41. A retracting table roller 42 whose rotation can be controlled is arranged on the retracting table 41, and when the container unit 10 reaches an appropriate position relative to the retracting table 41, the rotation is temporarily stopped. The pull-in table 41 moves the container unit 10 in the direction of the reversing section 50 and the container unit holding section 30, which is a direction perpendicular to the flow direction of the supply side conveyor 80. As a result of the movement, the container unit 10 is sandwiched and held by the container unit holding section 30. The container unit 10 that has completed harvesting is also separated from the container unit holding section 30 and moved in the downstream direction of the supply side conveyor 80.

[0024] The inverting unit 50 is a part that turns upside down the container unit 10 fixed by the container unit holding unit 30. The container unit holding unit 30 is fixed to a rotating arm 52 in the circumferential direction of a rotating shaft 51 connected to a motor and a gear (FIGS. 1 and 3). The rotation shaft 51 and the rotation arm 52 of the reversing unit 50 rotate forward and backward in 180-degree increments. Since the container unit 10 is held by the container unit holding portion 30, the container unit 10 also rotates in response to the rotation of the rotation shaft 51 and the rotation arm portion 52. When the container unit 10 is changed from an upright state to an inverted state, the rotating shaft 51 and the rotating arm 52 rotate 180 degrees counterclockwise as viewed from downstream of the conveyor (FIGS. 3(b) and 3(c)). When the container unit 10 is changed from an inverted state to an upright state, the rotating shaft 51 and the rotating arm 52 rotate 180 degrees clockwise as viewed from downstream of the conveyor (FIGS. 3(d) and 3(e)). Furthermore, when the container unit 10 is brought into an inverted state, the culture bottle 20 of the container unit 10 can be vibrated by suddenly stopping it, for example. Alternatively, when the container unit 10 is rotated into an inverted state, the rotation speed can be slowed down towards the end of the rotation, so that the force in the downward direction generated during the deceleration and gravity cause the culture medium 21 to shift toward the opening 22 of the culture bottle 20.

[0025] The cutting unit 60 is a part that cuts the shiitake mushrooms 24 in the culture bottle 20 from the vicinity of the base of the stem 25. The cutting unit 60 is made up of a cutter 61, a cutter holder 62, and a slide rail 63. A plurality of cutters 61 are held by a cutter holder 62. The cutter holder 62 is structured to cut the shiitake mushrooms 24 hanging from the openings of the culture bottles 20 of the inverted container unit 10 by using slide rails 63 to move across the container unit 10. In other words, the shiitake mushrooms 24 are cut by sliding the cutter 61 along the mouth of the culture bottle 20 from one end edge of the inverted container unit 10 to the opposite end edge.

[0026] Fig. 5 is a schematic diagram showing the device and the container unit 10 as viewed from below. As shown in Fig. 5(b), the cutting section 60 is disposed near one end of the container unit 10, and as shown in Figs. 5(c) and 5(d), it slides toward the other opposite end to cut the shiitake mushrooms 24. The number of cutters 61 corresponds to the number of culture bottles 20 lined up on one edge of the container unit 10. In this embodiment, four culture bottles 20 are lined up in one row, so four cutters 61 are used as the corresponding number. The corresponding number refers to the number of groups into which the culture bottles 20 are divided. One group may contain one or two culture bottles 20. If the number of cutters 61 does not correspond to the number of culture bottles 20, the shiitake mushrooms 24 growing in one culture bottle 20 will be cut by two cutters 61, resulting in misalignment of the cut surfaces.

[0027] The angle of the blade of the cutter 61 is preferably inclined at 8 to 15 degrees relative to one end of the container unit 10 toward the other end of the container unit 10. In this embodiment, the angle is set to 10 degrees (FIG. 5(a)). If the angle is less than 8 degrees, the cutter 61 will not be sharp enough to knock down the shiitake mushrooms 24, and the cut surface will be slanted, resulting in a decrease in the quality of the product. If the angle is greater than 15 degrees, it is necessary to increase the length of each cutter 61. If the length is increased, it will exceed the length of a general blade, making it difficult to procure. Therefore, by setting the angle between 8 and 15 degrees, the cutter 61 comes into contact with the stem 25 of the shiitake mushroom 24 at an appropriate angle, which allows for smoother cutting of the stem 25. Setting the angle to 10 degrees is even more preferable.

[0028] The moving speed of cutter 61 is 、5 A speed of 10 ms / s to 15 cm / s is preferable, and 10 ms / s is even more preferable. If the speed is less than 5 cm / s, the stems 25 of the shiitake mushrooms 24 are cut, but many wavy marks caused by the cutter 61 going back and forth remain on the cut surface, reducing the quality of the product. Also, if the speed is significantly slower than 5 cm / s, the partially cut shiitake mushrooms 24 will hang diagonally and sway, damaging the caps and other parts. If the speed is increased beyond 15 cm / s, the shiitake mushroom 24 will be pushed down before its stem 25 is cut.

[0029] The collecting section 70 is a section for collecting the cut off shiitake mushrooms 24. If the shiitake mushrooms 24 cut by the cutter 61 are far from the collection tray 90, they will fall at a high rate, and the quality will be reduced due to the impact of the fall and the contact between the falling shiitake mushrooms 24. Therefore, the damage caused by the fall of the shiitake mushrooms 24 is reduced by the two-stage action of lifting the collection tray 90 and pushing up the insole 91. It mainly consists of a collection tray base 71 on which the collection tray 90 is placed, and a push-up rod 75. The collection tray 90 is a dish-shaped body that receives and collects the shiitake mushrooms 24 that have been cut and dropped by the guide section 37. The collection tray 90 is shallow and dish-shaped overall. The bottom surface has a rough mesh that prevents the shiitake mushrooms 24 from passing through. It is made of resin or the like. The top surface of the dish is covered with a thin sheet called an insole 91. In this embodiment, the insole 91 is made of only a thin sheet (FIGS. 6(b) and 6(c)), but if it is made of only a thin sheet, it may not be stable and may become wavy or twisted when the insole 91 is pushed up by the push-up rod 75 (described later). In such a case, it is conceivable that the harvested shiitake mushrooms 24 may fall out of the insole 91, potentially damaging the shiitake mushrooms 24. Therefore, it is also preferable to use a slightly harder board material such as plastic cardboard with a soft urethane sheet laid on top of it as the insole 91. This prevents the insole 91 from twisting when pushed up by the push-up rod 75, thereby helping to reduce damage to the shiitake mushrooms 24. The recovery tray base 71 is provided with recovery rollers 74 that move and stop the recovery tray 90 coming from the pick-up conveyor 81 at an appropriate position. The container unit 10 is held and arranged upside down by the container unit holding section 30 directly above the collection section 70 (FIG. 6(a)).

[0030] The collection tray base 71 is arranged so as to be movable up and down by a shaft 73. To collect the shiitake mushrooms 24, the collection tray base 71 is moved to a predetermined height by a base cylinder 72. By moving it upward, the distance between the collection tray 90 and the shiitake mushrooms 24 that are cut and dropped can be shortened, and damage to the shiitake mushrooms 24 when they fall can be reduced (FIG. 6(b)).

[0031] The push-up rod 75 is a part that lifts the insole 91 from the collection tray 90. The push-up rod 75 is pushed upward by the push-up rod cylinder 76, pushing the insole 91 up through the mesh-like gaps in the bottom of the collection tray 90, and the insole 91 can be raised above the collection tray 90. In this state, the raised insole 91 can catch the shiitake mushrooms 24 that fall after being cut, further reducing damage to the shiitake mushrooms 24 (FIG. 6(c)). In this way, damage to the shiitake mushrooms 24 caused by falling can be reduced by the two-stage action of lifting the collection tray 90 and pushing up the insole 91.

[0032] The flow of the entire device will be explained with reference to Figures 1 and 3. Broadly speaking, it consists of two conveyor lines. Each line can smoothly move the container units 10 and collection trays 90 using conveyor rollers 82. The supply conveyor 80 line and the take-up conveyor 81 line are divided into two conveyors, upstream and downstream, and an area for harvesting various shiitake mushrooms 24 is located between the upstream and downstream conveyors. The container unit 10 flowing from the upstream of the supply conveyor 80 is stopped at an appropriate position in the retraction section 40. The state in which the container unit 10 is placed on the retraction table 41 is shown in FIG.

[0033] Thereafter, the retractable platform 41 carrying the container unit 10 moves toward the container unit holding section 30. The container unit 10 is fixed in all directions by the container unit holding section 30, and is in a state where it can be turned upside down (FIG. 3(b), holding step). The container unit holding section 30 is rotated 180 degrees around the rotation shaft 51 by the inverting section 50. As a result, the container unit 10 is placed upside down, or in a so-called inverted position, above the take-out conveyor 81 (FIG. 3(c), inverting process).

[0034] Looking at the take-up conveyor 81, a collection tray 90 flowing from upstream is moved and stopped at an appropriate position in the collection section 70. The collection section 70 moves the collection tray 90 upward directly below the container unit 10, and uses the push-up rod 75 to lift the insole 91. Above the collection section 70 is the cutting section 60, which slides the cutter 61 to cut the shiitake mushrooms 24 along the opening 22 of the culture bottle 20 (cutting process). The shiitake mushrooms 24 fall onto the collection tray 90 and are collected (Figure 3(d), collection process). After collection, the collection tray base 71 returns to the height of the downward conveyor, and the harvested shiitake mushrooms 24 are sent downstream to the pick-up conveyor 81.

[0035] After cutting the shiitake mushrooms 24, the container unit 10 is rotated by 180 degrees in the opposite direction to the previous rotation by the reversing section 50, and the container unit 10 is returned to its normal position (FIG. 3(e)). The container unit 10 is returned to the position of the supply conveyor 80 by the pull-in table 41 (FIG. 3(f)). After the shiitake mushrooms 24 have been cut, the container unit 10 is transported downstream by the supply conveyor 80. This series of operations allows the shiitake mushrooms 24 to be harvested efficiently.

[0036] The operation and effects of this embodiment will be described with reference to FIG. Figure 4(a) shows a culture bottle 20 in an upright position. Shiitake mushrooms 24 grow in a culture medium 21 inside the culture bottle 20, and the caps and stems 25 of the mushrooms 24 are exposed from the opening 22. However, during the growth of the mushrooms 24, some of the mushrooms 24 may bend and hang down from the opening 22, as shown in Figure 4(a). If the mushrooms are mechanically cut along the opening 22 in this state, the caps of some of the shiitake mushrooms 24 may be cut off or the stems 25 may be cut at an angle, which will cause problems in terms of the quality of the harvested product.

[0037] 4(b) shows the case where the culture bottle 20 is inverted. By inverting the culture bottle 20, the shiitake mushrooms 24 hang down with their caps facing downwards, which reduces the possibility of improper cutting compared to when the culture bottle 20 is upright. Therefore, cutting in an inverted state is effective.

[0038] 4(c) shows a case where the culture bottle 20 is subjected to vibration or impact or the rotation speed at the end of rotation is reduced when the culture bottle 20 is turned upside down. A possible example of the vibration is a vibrator that generates vibration. A possible example of the impact is when the container unit 10 is turned upside down in the turnover section 50, by hitting it hard against a stopper or the like, abruptly stopping the rotation, and then applying an impact as a reaction. When the culture bottle 20 is vibrated or impacted in an inverted state, or when the rotation speed is reduced towards the end of the rotation, the culture medium 21 moves slightly toward the opening 22 of the culture bottle 20 due to reaction or gravity. This causes the base of the shiitake mushroom 24, i.e., the protruding part, to approach the opening 22, allowing the mushroom 24 to be cut from the part closest to the base. 4(d) shows the harvest when the culture medium 21 is cut while shifted toward the opening 22 of the culture bottle 20. In this way, the harvest amount can be increased by applying vibration or impact to the culture bottle 20 or by slowing down the rotation speed at the end of the rotation.

[0039] Thus, according to the present invention, when cultivating mushrooms such as shiitake mushrooms in culture bottles, the grown mushrooms can be harvested in a short time without being missed, thereby improving harvesting efficiency and benefiting the user.

[0040] Furthermore, according to the present invention, when collecting the shiitake mushrooms 24, no human hands are required, and damage to the shiitake mushrooms 24 caused by holding them with hands can be avoided.

[0041] Furthermore, according to the present invention, the harvesting speed can be significantly improved to around 150 kg per hour with this device, compared to about 12 kg per hour per person when doing manual work. [Industrial Applicability]

[0042] The shiitake mushroom harvesting device of the present invention is a technology for efficiently harvesting mushrooms grown in culture bottles, and can also be applied to the harvesting of mushrooms other than shiitake mushrooms, and is believed to have great industrial applicability.
