[0036] In this embodiment, the leafy crop can be lettuce, or any root crop that needs to be leafed, such as corn plants, pepper plants, palm, etc. The leafy crop includes a stem body and leaves 7, and the leaves 7 are irregularly distributed on the outer surface of the stem body.

[0037] The fixing ring 1 is an annular structure, and the interior of the fixing ring 1 is a hollow structure. As a preferred embodiment, the fixing ring 1 is a polygonal ring, which can be a quadrilateral, pentagon, hexagon, octagon, etc., and can be set according to actual needs. When the fixing ring 1 is a polygonal shape, the side wall of the fixing ring 1 is a planar structure, which is helpful for the connection of the elastic component 2.

[0038] In this embodiment, the elastic component 2 includes a first connecting plate, a second connecting plate and an elastic member 23, wherein the elastic member 23 may be a member having an elastic deformation function, not limited to a spring, but may also be a member made of a non-metallic material with strong elastic deformation such as foam or polyurethane. The elastic member 23 shown in this embodiment is preferably a round wire spring, which can provide a relatively stable support for the first guide shaft 3 and the leaf cutter blade 4 on the second connecting plate. Specifically, the first connecting plate is arranged on the inner side wall of the fixing ring 1, the first connecting plate is fixedly connected to one end of the elastic member 23, and the other end of the elastic member 23 is connected to the second connecting plate. Specifically, the elastic component 2 is as shown in FIG. Figure 2 As shown, it is arranged on the fixing ring 1, that is, it extends from the edge of the fixing ring 1 toward the center point of the fixing ring 1. When there are multiple elastic components 2, the second connecting plates of the multiple elastic components 2 can form a passage around the center point of the fixing ring 1, and the stem body of the long-leaf crop can pass through this passage, but the leaves 7 of the long-leaf crop are scattered in all directions under the action of inertia and cannot pass through this passage completely.

[0039] In this embodiment, a first guide shaft 3 is provided on the second connecting plate, and the first guide shaft 3 has a first suspended end 31, and the first suspended end 31 extends toward the center point of the fixing ring 1, so as to fix the leaf cutting blade 4. Specifically, the leaf cutting blade 4 includes a first fixing portion 41 and a first cutting portion 42, the first fixing portion 41 is connected to the first suspended end 31, and the first cutting portion 42 has a blade for cutting leaves, and the blade is arranged toward the input direction of the long-leaf crop.

[0040] Here, the first fixing part 41 and the first cutting part 42 include multiple situations in the input direction of the long-leaf crop, such as: the first cutting part 42 and the first fixing part 41 are arranged in sequence along the input direction of the long-leaf crop, then the long-leaf crop will first contact the blade on the first cutting part 42 to achieve the removal of the leaves 7 of the stem body; for another example, the first fixing part 41 and the first cutting part 42 are arranged in sequence along the input direction of the long-leaf crop, then the long-leaf crop will first contact the inner side of the first fixing part 41, and then the first cutting part 42 will contact the long-leaf crop. Different settings can be set according to actual needs. It should be noted that the preset angles between the first cutting part 42 and the first fixing part 41 corresponding to different settings are also different. The preset angle can be an obtuse angle or an acute angle, and this embodiment does not limit this.

[0041] When using, please refer to Figure 4Preferably, the fixing ring 1 is arranged in a vertical direction, and the input direction of the long-leaf crop is a horizontal direction. Taking the conveying from left to right as an example, the long-leaf crop can be horizontally moved relative to the fixing ring 1 by setting a conveyor belt or the like. When the long-leaf crop is input into the fixing ring 1, due to its certain initial velocity, even if the conveyor belt is only transported to the left side of the fixing ring 1, the long-leaf crop will move into the fixing ring 1 under the action of inertia, and the leaf cutter blade 4 will abut against the outer surface of the long-leaf crop. When the radial size of the long-leaf crop changes, the leaf cutter blade 4 can be squeezed to compress the elastic member 23, and the leaf cutter blade 4 always maintains a state of abutting against the outer surface of the long-leaf crop. In this process, the blade 7 will scatter around due to its light and thin structure, so that the leaf cutter blade 4 abuts against the connecting root of the blade 7 and the stem body during the movement of the long-leaf crop, and then the blade on the leaf cutter blade 4 cuts off the blade 7 to complete the long leaf removal operation of the long-leaf crop.

[0042] In some optional embodiments, when long-leaf crops can be continuously input onto the conveyor belt, continuous cutting operation of the leaf cutter blade 4 can be achieved. This method changes the existing method of using the leaf cutter blade 4 to move with the long-leaf crops while the long-leaf crops remain stationary. Instead, the leaf cutter blade 4 is kept fixed while the long-leaf crops move relative to the leaf cutter blade 4, thereby significantly improving the leaf cutting efficiency.

[0043] See also Figures 1 to 3 In some embodiments, it further includes a first fixing plate 5 , the first fixing plate 5 is connected to the first guide shaft 3 at the first suspended end 31 , and the first fixing portion 41 is locked and connected to the first fixing plate 5 .

[0044] In this embodiment, the first fixing plate 5 is preferably a U-shaped structure, which is convenient for locking the first suspended end 31 and the first fixing plate 5. At the same time, the connection area between the first fixing plate 5 and the first fixing part 41 can be expanded, so as to make the connection between the leaf cutter blade 4 and the first guide shaft 3 more stable.

[0045] See also Figure 3 In some embodiments, the first guide shaft 3 further includes a second suspended end 32, and the second suspended end 32 protrudes out of the second connecting plate 22 toward the edge direction of the fixing ring 1; the elastic member 23 is a spring, and part of the elastic member 23 is sleeved on the outside of the second suspended end 32. In this embodiment, the second suspended end 32 is placed on the inner side of the elastic member 23, and the elastic member 23 may be bent during the compression process. When part of the first guide shaft 3 is placed in the elastic member 23, it can provide guidance for the elastic member 23 to prevent it from bending during the compression process, so that the elastic member 23 can be compressed back and forth along the axial direction of the first guide shaft 3.

[0046] See also Figures 1 to 4In some embodiments, the radial dimension of the fixing ring 1 gradually decreases from the input direction of the long-leaf crop according to a preset gradient; the first fixing portion 41 is parallel to the inner side wall of the fixing ring 1. In this embodiment, the fixing ring 1 is as Figures 1 to 3 As shown, the side wall of the fixing ring 1 is a truncated cone structure, which is adapted to the growth form of the stem body 6 of the long-leaf crop. Specifically, the stem body 6 is a conical structure with a smaller top and a larger root. When the leaves 7 on the stem body 6 are cut, their growth direction is the same as the growth form of the stem body 6. When the leaf cutting blade 4 is placed horizontally, the top leaves 7 will have a larger stem body, and the root stem body 6 will be over-cut. The structure of the fixing ring 1 shown in the present embodiment enables a certain inclination angle to exist between the first guide shaft 3 connected to the second connecting plate and the input direction of the long-leaf crop. The first fixing portion 41 locked with the first guide shaft 3 is parallel to the inner wall of the fixing ring 1. The connection relationship between the first fixing portion 41 and the first cutting portion 42 enables the blade of the first cutting portion 42 to be against the outer side of the stem body 6 at a certain angle, and to follow the growth morphology changes of the stem body 6 under the drive of the elastic component 2. When the blade is inclined to cut off the leaf 7, it is cut in the reverse direction of the growth direction of the rod body of the leaf 7, thereby improving the cutting efficiency of the leaf 7 and reducing the jamming frequency between the stem body 6 and the leaf cutting blade 4 during the cutting process of the leaf 7. At the same time, it can also improve the flatness of the incision of the leaf 7, making the stem body 6 more beautiful after cutting.

[0047] See also Figure 3 and Figure 4 In some embodiments, the first fixing portion 41 and the first cutting portion 42 are sequentially arranged along the input direction of the long-leaf crops. Preferably, the preset angle between the first fixing portion 41 and the first cutting portion 42 is an acute angle, that is, Figure 3 The structure shown in this way can make the long-leaf crops first abut against the outer wall of the first fixing part 41 when being input, and then abut against the first cutting part 42. When the diameter of the stem body 6 of the long-leaf crops is large, the first fixing part 41 will be pressed to drive the first cutting part 42 to gradually move toward the outer edge of the fixing ring 1, so as to achieve fine adjustment of the position of the first cutting part 42 relative to the stem body 6, and avoid the first cutting part 42 directly cutting off the tissue structure of the stem body 6 during the cutting process.

[0048] See also Figure 1 and Figure 2 In some embodiments, there are multiple elastic components 2, and the multiple elastic components 2 are circumferentially spaced and distributed on the inner wall of the fixing ring 1; there are multiple first guide shafts 3, and one first guide shaft 3 corresponds to one elastic component 2; there are multiple leaf cutter blades 4, and one leaf cutter blade 4 corresponds to one elastic component 2.

[0049] In some embodiments, the blades of the plurality of leaf cutting blades 4 enclose a cutting circle, and the radial dimension of the cutting circle is smaller than the radial dimension of the stem body.

[0050] In this embodiment, the number of elastic components 2, first guide shafts 3 and leaf cutter blades 4 corresponds one to one, and multiple elastic components 2 are spaced apart along the inner wall of the fixing ring 1. This arrangement enables the blades of multiple leaf cutter blades 4 to enclose a cutting circle, and the radial dimension of the cutting circle is smaller than the radial dimension of the stem body. There are many situations here. The radial dimension of the stem body includes multiple parts, such as the radial dimension of the top of the stem body and the radial dimension of the root of the stem body. The radial dimension of the cutting circle can be adjusted according to the actual cutting requirements, that is, according to the radial dimensions of different areas on the stem body to which reference is made. Specifically, the leaf cutter blade 4 can be fine-tuned by screwing the relative position of the first guide shaft 3 and the second connecting plate to adjust the radial dimension of the cutting circle.

[0051] The long-leaf crop includes a stem body and a blade 7, and the device includes a fixing ring 1, an elastic component 2, a first guide shaft 3 and a leaf cutting blade 4. The stem body is coaxial with the fixing ring 1, and the stem body can move axially relative to the fixing ring 1; the elastic component 2 includes a first connecting plate 21, a second connecting plate 22 and an elastic member 23, and the two ends of the elastic member 23 are connected to the first connecting plate 21 and the second connecting plate 22 respectively. The first connecting plate 21 is arranged on the inner side wall of the fixing ring 1, and the first connecting plate 21, the elastic member 23 and the second connecting plate 22 are connected along the inner side wall of the fixing ring 1. The edges of the fixing ring 1 are distributed in sequence toward the center point of the fixing ring 1; the first guide shaft 3 is connected to the second connecting plate 22, the first guide shaft 3 includes a first suspended end 31, and the first suspended end 31 protrudes out of the second connecting plate 22 toward the center point of the fixing ring 1; the leaf cutting blade 4 includes a first fixing portion 41 and a first cutting portion 42, the first fixing portion 41 is connected to the first suspended end 31, the first cutting portion 42 is arranged at a preset angle with the first fixing portion 41, and the blade of the first cutting portion 42 is arranged toward the input direction of the long-leaf crop. When in use, the fixing ring 1 is coaxially arranged with the input direction of the long-leaf crop, and the leaf cutting blade 4 can be against the outer surface of the stem body 6 during the input process of the long-leaf crop, and the long leaves are cut off in the form of reverse cutting, which changes the use mode of the prior art in which the leaf cutting blade 4 follows the movement of the long-leaf crop and the long-leaf crop remains stationary, but keeps the leaf cutting blade 4 fixed, and the long-leaf crop moves relative to the leaf cutting blade 4. As long as the long-leaf crop is continuously input, the leaf cutting operation of the long-leaf crop can be continuously maintained, which significantly improves the leaf cutting efficiency.
