Description

Technical Field

[0001] The present invention relates to the cutting of the stems of cultivated plants such as plants and fungi cultivated in a bottle-shaped cultivation container (hereinafter referred to as "cultivation bottle"), and more particularly to a technique for improving the quality of cutting the stems of cultivated plants. In addition, the cultivation bottle (bottle-shaped cultivation container) includes not only an independent bottle-shaped container but also a container obtained by dividing the container with a partition or the like. For the sake of convenience of explanation, the "cutting site" of the cultivated plant is expressed as "stem".

Background Art

[0002] Conventionally, in order to harvest cultivated plants such as plants and fungi cultivated in a cultivation bottle, when cutting the stem of the cultivated plant, a thin blade was fixed to the tip of a wedge-shaped pedestal for cutting. However, depending on the thickness of the stems of plants and mushrooms, the stem may hit the wedge part before the cutting is completed. In the case of mushrooms, the stem may crack or become distorted. In the case of vegetables, the cut surface becomes discontinuous, which deteriorates the appearance and may also cause faster pain. As one countermeasure, it is conceivable to lengthen the blade tip, but it is difficult to cope with this because the processing accuracy becomes high and the possibility of breakage also increases. In addition, in order to improve the efficiency of cutting the stem part, when cutting the cultivated plants of a plurality of cultivation bottles at once, a plurality of blades are used according to the size of the cultivation bottles. At that time, when arranging a plurality of blades, a blade that matches the position and size of the cultivation bottle is required, which is a special product, and the management of delivery time and inventory is complicated. Therefore, there has been a demand for a cutting structure that uses a general-purpose blade different from the required dimensions to prevent the stem from hitting a part other than the blade during cutting.

[0003] Various technologies have been proposed to address these problems. For example, a mushroom harvesting device (see Patent Document 1) that can easily cut off unwanted parts of mushrooms cultivated in cultivation bottles has been proposed and is now known technology. More specifically, the mushroom harvesting device harvests mushrooms that have grown and extended upward from the mouth of the mushroom cultivation bottle by cutting them at the stem using a cutting device, and the cutting device is provided with blades facing each other corresponding to each cultivation bottle, and has two blades that are angled with respect to the direction of travel of the blades. However, the structure based on this prior art requires the use of blades with dimensions that match the dimensions of the cultivation bottle, and therefore, the above-mentioned problems have not yet been resolved.

[0017] The crop cutting device 1 forms part of a harvesting device for harvesting vegetables such as leafy greens and mushrooms cultivated in cultivation bottles, and is a device for cutting the stems of vegetables and mushrooms. The crop cutting device 1 will be described along with FIG. 1. FIG. 1 is a schematic diagram depicting only the main part of the crop cutting device. In the crop harvesting device, when cutting the stems 71, 76 of the mushrooms 70 and vegetables 75 cultivated in the cultivation bottle 60, the cultivation bottle 60 is turned upside down for cutting. FIG. 1 shows the cutting operation as seen from below. The aligned cultivation bottles 60 are inverted by the cultivation bottle holding part 12. Then, the cutting part 20 is slid along the mouth 61 of the cultivation bottle 60 to cut the stems 71, 76 of the crops. The crop cutting device 1 includes a holder drive part 10, a rail for holder sliding 11, a cultivation bottle holding part 12, and a cutting part 20.

[0018] The cultivation bottle holding part 12 is a part for holding the cultivation bottle 60, holds a plurality of cultivation bottles 60, and while holding them, inverts the cultivation bottle 60 so that it is upside down, causing the mushrooms 70, vegetables 75, etc. extending from the mouth 61 of the cultivation bottle 60 to hang downwards. The cultivation bottle holding part 12 holds the cultivation bottles 60 at a time, for example, in units of 4 rows and 4 columns. The rail for holder sliding 11 is a rail for moving the cutting part 20 that cuts the stems 71, 76 of the crops, and moves the cutting part 20 from one end to the other end of the cultivation bottle 60. The holder drive part 10 vibrates the cutting part 20 in the longitudinal direction of the blade part 50. When cutting the stems 71, 76 of the crops with the blade part 50, by vibrating the blade part 50 in the longitudinal direction, the stems 71, 76 can be cut smoothly. The vibration amplitude is, for example, about 8 mm.

[0019] The cutting part 20 is a part for cutting the stems 71, 76 of the crops. It cuts the stems 71, 76 of the mushrooms 70 and vegetables 75 in the cultivation bottles 60 arranged in a row at one time. The cutting part 20 consists of a holder part 30, a pressing part 40, and a blade part 50.

[0020] The holder portion 30 is the main body of the cutting portion 20 and has a length that covers the cultivation bottles 60 arranged in a row. The holder portion 30 has a single arm portion 31 and multiple tongue-shaped portions protruding from the arm portion, spaced apart from the cultivation bottle. The arm portion 31 is rod-shaped and is the main part of the holder portion 30. The arm portion 31 has tongue-shaped portions 32 protruding in the direction of cutting the mushrooms 70 and vegetables 75 in the cultivation bottle 60, which is the lateral direction of the arm portion 31. There is a gap between the blade portion 50 and the arm portion 31. The tongue-shaped portion 32 holds the end portion of the blade portion 50 and positions the blade portion 50 at a distance G from the arm portion 31. The tongue-shaped portion 32 is positioned between the cultivation bottles 60. If there are four cultivation bottles 60 in a row, four blade portions 50 are also required. The tongue-shaped portion 32 holds the ends of the blade portions 50 by gripping them, so it is positioned in a total of five places (Figure 2(b)). The holder portion 30 has screw holes 34 for fixing the blade portion 50 with the pressing portion 40. The tip of the tongue-shaped portion 32 is provided with a blade-holding portion 33, which has a recess equal to the thickness of the blade portion 50, in order to hold the blade portion 50. There is a stepped portion 36 between the other parts and the blade-holding portion 33, which allows for the positioning of the blade portion 50. The blade portion 50 is held by being sandwiched between the blade-holding portion 33 and the pressing portion 40 (Figure 2(c)).

[0021] There are multiple pressing parts 40, which, together with the holder part 30, are for holding the blade part 50 and are fixed to the holder part 30. They are generally thin and short rod-shaped, have screw holes 41, and are fixed to the tongue-shaped part 32 with screws 80, thereby clamping and holding the blade part 50 (Figure 2(a)).

[0022] The blade portion 50 is a general-purpose blade. For example, a commercially available cutter blade can be used. The blade portion 50 is a parallelogram with an acute, obtuse, or right-angled tip. Multiple blade portions 50 are arranged in the longitudinal direction of the blade portions 50, and the ends of adjacent blade portions 50 are held together by the blade holding portion 33 and the pressing portion 40. The blade portion 50 has a longitudinal edge, with the edge on the cutting edge side designated as the cutting edge side 51, and the edge opposite the cutting edge designated as the spine side 52. The edge towards the tip is designated as the tip end side 53, and the edge on the base side is designated as the base end side 54. In this embodiment, an example is given of a blade portion 50 in which the tip of the blade is acute, and the length of the blade edge side 51 and the spine side 52 is 100 mm and the width is 18 mm. The difference in width between the blade edge side 51 and the spine side 52 is 10 mm, and the angle of the tip is approximately 60 degrees.

[0023] The process of cutting the stem 71 of the mushroom 70 will be explained in accordance with Figure 3. First, the conventional cutting process at the cutting section 90 will be explained following Figures 3(e) to (h). In conventional cutting sections, the side of the blade section 50 opposite to the cutting edge is fixed by a wedge-shaped fixing part, the wedge portion 91. The blade section is the same as that of this embodiment. The conventional cutting section 90 slides parallel to the mouth 61 of the cultivation bottle 60 (Figure 3(e)). The blade section 50 hits the stem 71 of the mushroom 70 and cuts the stem 71 horizontally. Once the cut has progressed beyond a certain point, the wedge section 91 hits the stem 71 (Figure 3(f)). The wedge portion 91 pushes the stem 71 apart, causing many cracks to form on the cut surface of the stem 71 (Figure 3(g)). In this state, the cutting of the stem 71 is completed, resulting in a cracked and discontinuous cut surface on the stem 71 of the mushroom 70, which significantly reduces its quality as a product (Figure 3(h)).

[0024] Next, the cutting process at the cutting section 20 of this embodiment will be explained with reference to Figures 3(a) to 3(d). The blade portion 14 is fixed to the holder portion 30 at its longitudinal ends, the tip end 53 and the base end 54. In the central part of the blade, there is a gap G between the spine side 52 and the arm portion 31. Due to this gap G, the distance between the blade tip side 51 and the arm portion 31 is greater than the stem 71 of the mushroom 70. The blade 50 slides parallel to the mouth 61 of the cultivation bottle 60 (Figure 3(a)). The blade 50 hits the stem 71 of the mushroom 70 and cuts the stem 71 horizontally (Figure 3(b)). As the blade 50 cuts the stem 71, the arm 31 at the rear of the blade 50 is sufficiently far from the stem 71. In other words, while the blade is cutting the stem 71 of the mushroom 70, the stem 71 of the mushroom 70 does not come into contact with the arm of the holder. Therefore, the arm 31 does not compress or spread the stem 71 (Figure 3(c)). Since the arm portion 31 does not come into contact with the stem 71, the cutting of the stem 71 is completed, resulting in a clean, crack-free circular cut surface of the mushroom 70, improving its quality as a product (Figure 3(d)).

[0025] Thus, according to this embodiment, when cutting the stem 71 of the mushroom 70, the stem 71 does not come into contact with any part other than the blade, making it less likely for the stem 71 to crack or become distorted, and allowing for the harvesting of high-quality mushrooms 70.

[0026] The process of cutting the stems 76 of the vegetables 75 will be explained in accordance with Figure 4. As an example of a vegetable, let's look at red leaf lettuce. First, the conventional cutting process at the cutting section 90 will be explained following Figures 4(e) to (h). In conventional cutting sections, the side of the blade section 50 opposite to the cutting edge is fixed by a wedge-shaped fixing part, the wedge portion 91. The blade section is the same as that in this embodiment. The conventional cutting section 90 is slid parallel to the mouth 61 of the cultivation bottle 60 (Figure 4(e)). The blade section 50 comes into contact with the stem 76 of the vegetable 75 and cuts the stem 76 horizontally. Once the cutting progresses beyond a certain point, the wedge section 91 comes into contact with the stem 76 (Figure 4(f)). The wedge portion 91 pushes the stem 76 apart, causing many cracks to form on the cut surface of the stem 76 (Figure 4(g)). Furthermore, the cut surface is not flat, resulting in an unsightly appearance. Since the cutting of the stem 76 is completed in this state, the cut surface of the stem 76 of the vegetable 75 becomes cracked and discontinuous, significantly reducing its market quality (Figure 4(h)). In the case of red leaf lettuce, the cut surface discolors quickly, which lowers its market value.

[0027] Next, the cutting process at the cutting section 20 of this embodiment will be explained with reference to Figures 4(a) to 4(d). The blade portion 14 is fixed to the holder portion 30 at its longitudinal ends, the tip end 53 and the base end 54. In the central part of the blade, there is a gap G between the spine side 52 and the arm portion 31. This gap makes the distance between the blade tip side 51 and the arm portion 31 greater than the stem 76 of the vegetable 75. The blade 50 slides parallel to the mouth 61 of the cultivation bottle 60 (Figure 4(a)). The blade 50 hits the stem 76 of the vegetable 75 and cuts the stem 76 horizontally (Figure 4(b)). As the blade 50 cuts the stem 76, the arm 31 at the rear of the blade 50 is sufficiently far from the stem 76. In other words, while the blade is cutting the stem 76 of the vegetable 75, the stem 76 of the vegetable 75 does not come into contact with the arm of the holder. Therefore, the arm 31 does not compress or spread the stem 76 (Figure 4(c)). Since the arm portion 31 does not come into contact with the stem 76, the cutting of the stem 76 is completed, resulting in a flat, crack-free cut surface of the vegetable 75, improving its quality as a product (Figure 4(d)).

[0028] Thus, according to this embodiment, when cutting the stem 76 of the vegetable 75, the stem 76 does not come into contact with any part other than the blade, making it less likely for the stem 76 to crack or become distorted, and allowing for the harvesting of high-quality vegetables 75.

[0029] The relationship between the blade holding portion 33 and the blade portion 50 of the holder portion 30 will be explained in accordance with Figure 5. Figure 5(a) shows the area around the blade holder 33 of A in Figure 2(b). Similarly, Figure 5(b) shows the area around the blade holder 33 of B, and Figure 5(c) shows the area around the blade holder 33 of C. If the outer diameter of the cultivation bottle 60 in this embodiment is, for example, 95 mm, then it is optimal for the length of the blade portion 50 held by the blade holding portion 33 to also be 95 mm. However, in order to make the length of the blade portion 50 95 mm, a special blade must be prepared, which takes time to manufacture and is complicated to manage. Therefore, in this embodiment, the structure is designed to allow the use of commercially available cutter blades. Here, a commercially available cutter blade with a long side of 100 mm is used. The overall shape is a parallelogram, and the amount of longitudinal displacement between the cutting edge side 51 with the blade and the opposite side, the spine side 52, is approximately 10 mm.

[0030] Since there are four rows of cultivation bottles, four commercially available cutter blades, the blade sections 50, are used. The ends of the four blade sections are aligned and held without overlapping. Adjacent blade sections 50 may touch each other, or there may be a certain gap between them. There are five corresponding blade-holding sections 33. Three of these are structured to hold two adjacent blade sections 50. Figure 5 shows the positional relationship between the three blade-holding sections 33 and the blade sections 50. The width of the blade holding portion 33 is 10 mm, and the amount of misalignment between the cutting edge side 51 and the spine side 52 of the blade portion 50 is also approximately 10 mm.

[0031] The spacing between the blade holders 33 is 95 mm, and the longest side of the blade 50 is 100 mm. Therefore, the spacing between the blade holders 33 is shorter than the length of one side in the longitudinal direction of the blade 50, and the difference between the two dimensions is 5 mm. Consequently, the position of the end edge of the blade 50 relative to the blade holders 33 differs for each blade holder 33. Of the five blade holding parts 33, the central blade holding part 33 B is used to align the blade, while the left and right blade holding parts 33 are used to gradually shift the position of the blade. At the central position B, the edges of adjacent blade portions 50 are positioned in the blade holding portion 33 with approximately the same area. The clamped areas R2 and S2 are roughly equal. The width of the blade holder 33 is 100 mm, the blade portion 50 is a parallelogram, and the difference between the tip side 51 and the spine side 52 is approximately 10 mm. Therefore, the end edge of the blade portion 50 is tangent to one side and the other side in the width direction of the blade holder 33 (Figure 5(b)). In other words, one of the blade-holding portions 33, B, holds all the edges of the adjacent blade portions 50.

[0032] In the blade holding portion 33 of A, the positional relationship between the adjacent blade portion 50 and the blade holding portion 33 will be different from that of B. The distance between A and B is 95 mm, and the length of the long side of the blade portion 50 is 100 mm, so the position shifts by 5 mm. As a result, the clamping area S1 on the tip end side 53 of the blade portion 50 increases, and the clamping area R1 on the base end side 54 decreases. Although the clamping area on the R1 side is small, the blade portion 50 is highly rigid, and even if only a portion of the base edge 54 rests on it, there is no problem in holding the blade portion 50. In addition, since the base edge 54 is in contact with the stepped portion 36, some of the force when cutting mushrooms 70 or vegetables 75 can be absorbed by the stepped portion 36.

[0033] Similarly, in the blade holding portion 33 of C, the clamping area S3 on the tip end side 53 of the blade portion 50 decreases, while the clamping area R3 on the base end side 54 increases. Although the clamping area on the S3 side is small, the blade portion 50 is highly rigid, and even if only a portion of the tip edge 53 is resting on it, there is no problem in holding the blade portion 50.

[0034] To rephrase the relationship between the blade holding portion 33 and the blade portion 50, if the width of the blade holding portion 33 is 10 mm and its length is equal to or greater than the longitudinal displacement of the blade tip side 51 and the spine side 52, then some of the blade holding portions 33 can grip all of the edges of adjacent blade portions 50, and other blade holding portions 33 adjacent to some of the blade holding portions can grip at least half, or 5 mm or more, of each of the edges of adjacent blade portions 50. By using these dimensions, blades of different dimensions than the holding interval can be held stably. If the blade is rectangular, the tolerance for the difference between the mounting position and the length of the blade portion 50 is almost zero.

[0035] Furthermore, by bringing the ends of the blades into contact with each other, the force applied to the blade 50 when cutting cultivated plants can be distributed to the ends of adjacent blades 50, which is preferable. For example, in C, the blade portion 50, which is held by the tip edge 53, is not supported by the stepped portion 36. However, by bringing the tip edge 53 into contact with the base edge 54 of the adjacent blade portion 50, the force applied to the blade portion 50 when cutting cultivated material can be distributed to the base edge 54.

[0036] A modified example will be explained with reference to Figure 6. In the embodiment described above, the two blade portions 50 are held by being sandwiched between the blade holding portion 33 and the pressing portion 40. However, if there is variation in the thickness of the blade portions 50, it may be possible to hold only one blade portion 50 and not be able to sufficiently sandwich the other blade portion 50. In that case, there is a risk that the blade portion 50 that is not sandwiched may fall out. Therefore, the blade portion 50 is designed to prevent it from falling off even in such cases. As shown in Figure 6(a), a rim 35 is provided at the tip of the blade holding portion 33. Figure 6(b) shows the state in which the blade portion 50 is positioned. The positional relationship between the blade holding portion 33, the blade portion 50, and the pressing portion 40 is shown in the cross-sectional view in Figure 6(c). The blade portion 50 is restricted in the front-to-back direction by the stepped portion 36 and edge portion 35 of the blade holding portion 33, so the blade portion 50 will not fall off. Furthermore, even when only a portion of the tip edge 53 of the blade portion 50 is held by the blade holding portion 33, the presence of the edge portion 35 allows for stable holding (Figure 6(d)).

[0037] Alternatively, the edge portion 42 may be attached to the pressing portion 40 side, as shown in Figure 6(e). In this case, the blade portion 50 is stably held by the stepped portion 36 of the blade holding portion 33 and the stepped edge portion 42 of the pressing portion 40. In other words, the tip of the blade holding portion 33 or the pressing portion 40 has an edge portion 42 that restricts the movement of the blade portion 50 in the direction of the cutting edge. [Industrial applicability]
