Description

Technical Field

[0001] The present invention belongs to the technical field of harvesting growing crops, and more specifically, relates to an integrated mulberry leaf harvester. Background Art

[0003] Most of the existing mulberry leaf harvesting equipment directly shears the mulberry leaves at the petiole or directly strips the mulberry leaves from the mulberry branches through friction. However, these two mulberry leaf harvesting modes not only have low efficiency but also pose a risk of accidentally injuring the mulberry branches, thus affecting the ability of the mulberry branches to produce mulberry leaves again.

[0004] For example, for the patent application with the application number "202323465795.7" and the invention title "A Mulberry Leaf Picking Device", by installing two semi-circular pipe pieces on the pruning shears, after the end of the mulberry leaf branch passes through between the two semi-circular pipe pieces, the operator pushes the pruning shears along the length direction of the mulberry leaf branch so that the end of the semi-circular pipe piece abuts against the mulberry leaf petiole, thereby realizing the breaking of the mulberry leaf petiole from its connection position with the mulberry leaf branch. However, when pruning the mulberry leaf petiole with the pruning shears, the mulberry branch is easily accidentally injured by the pruning shears, causing damage to the phloem of the mulberry branch. Anatomical tests show that this process results in a 65% damage rate of the vascular bundles of the mulberry branch, directly blocking the transportation of water and nutrients in the mulberry branch, thus affecting the production capacity of the mulberry branch. For the patent application with the application number "202322767632.8" and the invention title "A Mulberry Leaf Collection Mechanism", the mulberry leaf collection mechanism has a mulberry branch gripper including at least two clamping and tensioning wheel groups and a mulberry branch stripping belt installed on the clamping and tensioning wheel groups, enabling the mulberry branch to abut between the two mulberry branch clamping belts and move along with the two mulberry branch clamping belts, and then through a mulberry leaf stripper including at least one stripping and tensioning wheel group and a mulberry leaf stripping belt installed on the stripping and tensioning wheel group, to collect complete mulberry leaves. When using the stripping and tensioning wheel group or the mulberry leaf stripping belt to strip the mulberry leaves, it is difficult to control the stripping force applied to the mulberry leaves. When the stripping force exceeds 5 N (the measured stripping force reaches 8 - 12 N), it will cause the epidermal cell layer of the branch to peel off, forming a wound surface with a diameter of 1 - 3 mm. Through comparative tests, in the mulberry orchard using this process, the branch regeneration cycle is extended by 23 days, and the new bud germination rate drops by 41%, thus reducing the ability of the mulberry branch to produce mulberry leaves again. Summary of the Invention

[0005] The technical problem to be solved by the present invention is how to improve the efficiency of harvesting mulberry leaves. In view of the above problems, the present invention provides an integrated mulberry leaf harvester, which can prevent damage to the mulberry branches of the mulberry tree while automatically harvesting mulberry leaves, thereby ensuring the ability of the mulberry branches to produce mulberry leaves after harvesting.

[0006] The technical solution of the present invention to solve the above technical problems is to provide an integrated mulberry leaf harvester, including a frame and a collection mechanism. The collection mechanism is arranged on the frame and is used for collecting mulberry leaves. It further includes:

[0007] The leaf cutting mechanism is arranged on the vehicle frame. The leaf cutting mechanism includes two cutting assemblies, which are respectively arranged on the left and right sides of the vehicle frame. The two cutting assemblies have the same structure and each includes a first transmission shaft, a sprocket and a chain ring.

[0008] Two deflecting assemblies are symmetrically arranged on the left and right sides at the front end of the vehicle frame.

[0009] The leaf cutting mechanism is arranged on the vehicle frame. The leaf cutting mechanism includes two cutting assemblies, which are respectively arranged on the left and right sides of the vehicle frame. The two cutting assemblies have the same structure and each includes a first transmission shaft, a sprocket and a chain ring. The first transmission shaft is rotationally connected to the vehicle frame, and a power device is connected to the first transmission shaft. The sprocket is arranged on the first transmission shaft, and the chain ring is engaged with the sprocket by teeth. A plurality of cutters are arranged on the chain ring. The two deflecting assemblies are used to deflect mulberry branches between the chain rings of the two cutting assemblies.

[0010] When the chain rings of the two cutting assemblies move in opposite directions at the same speed, the cutters on the closer sides of the two cutting assemblies are opposed to each other. The two opposed cutters form an annular cutting edge. The annular cutting edge surrounds the mulberry branches between the chain rings and is used to cut the mulberry leaves on the mulberry branches.

[0011] Preferably, the cutter is of a block structure. An arc-shaped groove is arranged on one side of the cutter, and the edge part of the arc-shaped groove is an arc-shaped cutting edge. The annular cutting edge is formed by the arc-shaped cutting edges on the two opposed cutters. A plurality of suction cups are arranged in the arc-shaped groove. The plurality of suction cups are attached to the mulberry branches, and the plurality of suction cups are used to apply a clamping force to the mulberry branches.

[0012] Preferably, the chain ring of each cutting assembly includes an arc part and a straight part. The arc part of each chain ring is engaged with the sprocket by teeth. The straight parts of the two chain rings are parallel, and the cutters on the straight parts on the closer sides of the two chain rings are opposed to each other.

[0013] Preferably, the two deflecting assemblies have the same structure and each includes a reel and a second transmission shaft. The reels of the two deflecting assemblies are both horizontally arranged at the front end of the vehicle frame. The reel is connected to the second transmission shaft. The second transmission shaft is vertically arranged and rotationally connected to the vehicle frame. The power device is connected to the second transmission shaft. A plurality of arc-shaped reel blades are arranged on the outer edge of the reel. The power device drives the two reels to rotate in opposite directions. Under the action of the plurality of arc-shaped reel blades on the two reels, the mulberry branches at the front end of the vehicle frame can be deflected between the chain rings of the two cutting assemblies.

[0014] Preferably, the collection mechanism includes two conveyor belts and a collection box. The two conveyor belts and the collection box are symmetrically arranged on the left and right sides of the vehicle frame. The two conveyor belts are arranged in a V-shaped structure. One end of each conveyor belt is arranged at the lower end of a chain loop, and the other end of each conveyor belt is arranged at the top of a collection box. The conveyor belts are used to convey the mulberry leaves cut by the annular knife edge into the collection box.

[0015] Preferably, a plurality of partition plates are provided on each conveyor belt. The length direction of each partition plate is the same as the length direction of the vehicle frame. The partition plates are used to prevent the mulberry leaves from slipping off the conveyor belt.

[0016] Preferably, a transmission mechanism is further included. The transmission mechanism includes a main drive shaft and a plurality of pulley mechanisms. The main drive shaft is horizontally arranged and rotatably connected to the vehicle frame. The main drive shaft is connected to the power device through a pulley mechanism. The second drive shaft is tooth-connected with a horizontal gear shaft. The horizontal gear shaft is connected to the main drive shaft through a pulley mechanism. The conveyor belt is connected to the main drive shaft through a pulley mechanism.

[0017] Preferably, a central vertical plate is provided on the vehicle frame. An L-shaped handle is provided on each side of the central vertical plate. The two L-shaped handles are symmetrically arranged on both sides of the central vertical plate.

[0018] Preferably, a traveling mechanism is provided on the vehicle frame. The traveling mechanism includes a front left wheel, a front right wheel, a central left wheel, and a central right wheel. The front left wheel, the front right wheel, the central left wheel, and the central right wheel are all connected to the vehicle frame. The tire sizes of the front left wheel, the front right wheel, the central left wheel, and the central right wheel have multiple specifications.

[0019] Preferably, the plurality of arc-shaped reel bars are respectively arranged at the upper end and the lower end of the reel wheel. The arc-shaped reel bars at the upper end of the reel wheel are staggered from the arc-shaped reel bars at the lower end of the reel wheel.

[0020] The beneficial effects of the present invention are as follows: By driving the vehicle frame to move in the mulberry field, the two gathering components gather the mulberry branches at the front end of the vehicle frame into the leaf cutting mechanism. The power device drives the sprocket to rotate, thereby driving the rotation of the multiple cutters on the chain loop. As the gathering components gather, the mulberry branches are pushed between the two chain loops. The cutters on the two chain wheels on the closer side move from the front end of the vehicle frame to the rear end of the vehicle frame. The cutters on the two chain wheels on the closer side are sequentially aligned at the front end of the vehicle frame, thereby forming an annular knife edge. When the two cutters are aligned, the mulberry branches are wrapped between the two cutters. With the drive of the chain loop, the mulberry branches between the two cutters generate an axial movement relative to the two cutters. The annular knife edge cuts the mulberry leaves on the mulberry branches, which can prevent damage to the mulberry branches of the mulberry tree, ensure the ability of the mulberry branches to produce mulberry leaves after harvesting, thereby ensuring the output of the mulberry field, and the harvesting machine can achieve integrated harvesting, greatly increasing the harvesting efficiency of mulberry leaves.

[0021] By setting multiple suction cups, the flexible adsorption effect of the suction cups can dynamically balance the relative movement between the mulberry branches and the cutting tool, significantly reducing the radial sliding offset of the circular cutting edge of the cutting tool during the cutting process, ensuring that the circular cutting edge accurately cuts into the base of the petiole (depth < 2 mm), and preventing accidental injury to the phloem of the mulberry branches due to the radial shaking of the mulberry branches. Thus, the "flexible locking-uniform force application-precise depth limitation" trinity of protective cutting is achieved, thereby greatly reducing the risk of mechanical damage to the mulberry trees.

[0031] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the following further elaborates on the present invention in conjunction with the attached Figures 1 - 7 drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] As Figures 1 - 7 shown, the present invention provides an integrated mulberry leaf harvester, which includes a vehicle frame 101 and a collection mechanism 102. The collection mechanism 102 is arranged on the vehicle frame 101 and is used for collecting mulberry leaves. It further includes: a leaf cutting mechanism and two dialing components 103. The two dialing components 103 are symmetrically arranged on the left and right sides of the front end of the vehicle frame 101. The leaf cutting mechanism is arranged on the vehicle frame 101. The leaf cutting mechanism includes two cutting components. The two cutting components are respectively arranged on the left and right sides of the vehicle frame 101. The two cutting components have the same structure and both include a first transmission shaft 104, a sprocket 105 and a chain ring 106. The first transmission shaft 104 is rotatably connected to the vehicle frame 101. The first transmission shaft 104 is connected with a power device 107. The sprocket 105 is arranged on the first transmission shaft 104. The chain ring 106 is in tooth engagement with the sprocket 105. A plurality of cutting tools 108 are arranged on the chain ring 106. The two dialing components 103 are used for dialing the mulberry branches towards the space between the chain rings 106 of the two cutting components. When the chain rings 106 of the two cutting components move in opposite directions at the same speed, the cutting tools 108 on the closer sides of the two cutting components are aligned with each other. The two aligned cutting tools 108 form an annular cutting edge 109. The annular cutting edge surrounds the mulberry branches between the chain rings 106. The annular cutting edge 109 is used for cutting the mulberry leaves on the mulberry branches.

[0033] Now briefly describe the working principle of the above embodiment:

[0034] The minimum distance between two chain links 106 is approximately twice the maximum diameter of the mulberry branches to ensure that the mulberry branches can pass through the middle between the two chain links 106. On each link of the above-mentioned chain link 106, two groups of positioning studs are provided. K-shaped attachment plates are connected to the two groups of positioning studs. Positioning pin holes are opened on both sides of the K-shaped attachment plate. The positioning pin hole on one side of the K-shaped attachment plate is connected to the positioning stud of the previous link, and the positioning pin hole on the other side of the K-shaped attachment plate is connected to the positioning stud of the next link. The cutter 108 is fixed on the link, so that the cutter 108 can move along an orderly path together with the chain link 106. When this harvester is in use, the driving frame 101 is driven to move in the mulberry field, and the two deflector assemblies 103 are driven to act. The two deflector assemblies 103 deflect the mulberry branches at the front end of the frame 101 into the leaf cutting mechanism. At the same time, the power device 107 drives the first transmission shaft 104 of the cutting assembly to rotate. The first transmission shaft 104 drives the sprocket 105 to rotate. The sprocket 105 drives the chain link 106 to rotate. The chain link 106 drives the multiple cutters 108 thereon to rotate. Since the cutters 108 on the closer sides of the chain links 106 of the two cutting assemblies are opposed to each other, the two opposed cutters 108 form an annular cutting edge 109. With the deflection of the deflector assembly 103, the mulberry branches are pushed between the two chain links 106. When the two chain wheels rotate in opposite directions, the cutters 108 on the closer sides of the two chain wheels move from the front end of the frame 101 to the rear end of the frame 101. During this process, the cutters 108 on the closer sides of the two chain wheels are sequentially aligned at the front end of the frame 101, thus forming the annular cutting edge 109. When the two cutters 108 are aligned, the mulberry branches are wrapped between the two cutters 108. With the drive of the chain link 106, the two aligned cutters 108 move towards the rear end of the frame 101. During this process, the mulberry branches between the two cutters 108 generate an axial movement relative to the two cutters 108, so as to cut the mulberry leaves on the mulberry branches by using the annular cutting edge 109 formed by the two cutters 108, so that while cutting the mulberry leaves, the mulberry branches can be prevented from being damaged and the ability of the mulberry branches to continue producing mulberry leaves can be protected. The cut mulberry leaves can be collected by the collection mechanism 102, thus realizing the integration of harvesting, and greatly increasing the harvesting efficiency of the mulberry leaves.

[0035] The integrated mulberry leaf harvester of the present invention can prevent damage to the mulberry branches of the mulberry tree while automatically harvesting the mulberry leaves, thereby ensuring the ability of the mulberry branches to produce mulberry leaves after harvesting, and thus ensuring the output of the mulberry field. And this harvester can realize the integration of harvesting, greatly increasing the harvesting efficiency of the mulberry leaves.

[0036] On the basis of the above-mentioned embodiment, in order to further prevent the annular cutting edge 109 of the cutter 108 from damaging the mulberry branches.

[0037] Such as Figure 2 and Figure 7As shown, the tool 108 is a block structure, and an arc-shaped groove 201 is provided on one side of the tool 108. The edge of the arc-shaped groove 201 is an arc-shaped blade 202. The annular blade 109 is formed by the arc-shaped blades 202 on the two matching tools 108. A plurality of suction cups 203 are provided in the arc-shaped groove 201, and the plurality of suction cups 203 are in contact with the mulberry sticks, and the plurality of suction cups 203 are used to apply clamping force to the mulberry sticks.

[0038] By arranging multiple suction cups 203 in the arc-shaped groove 201 on the tool 108, the suction cups 203 are made of flexible silicone or elastic polymer material. The multiple suction cups 203 simulate the microscopic grooves and adaptive adsorption characteristics of octopus tentacles. When the tool 108 contacts the mulberry stem, the micron-level a depression on the inner wall of the suction cup 203 quickly fits the surface of the mulberry stem due to the negative pressure effect or passive deformation, and adaptive clamping is achieved by increasing the contact area and surface friction. Therefore, when facing mulberry stems with different diameters (3-15mm) or uneven surfaces, the suction cup 203 can shrink or expand with the deformation, evenly disperse the clamping pressure, and avoid traditional rigid clamps causing local indentations or epidermal tears on the surface of the mulberry stem. Furthermore, the flexible adsorption effect of the suction cup 203 can dynamically balance the relative movement between the mulberry branch and the cutter 108, significantly reducing the radial sliding deviation of the annular blade 109 of the cutter 108 during the cutting process, ensuring that the annular blade 109 accurately cuts into the base of the petiole (depth <2mm) without accidentally damaging the phloem of the mulberry branch due to radial shaking of the mulberry branch, thereby achieving the three-in-one protective cutting of "flexible locking-uniform force-precise depth limitation", thereby greatly reducing the risk of mechanical damage to the mulberry tree.

[0039] The material of the cutter 108 is cemented carbide or high speed steel.

[0040] As a preferred solution, Figure 1 and Figure 2As shown, each chain link 106 of the cutting assembly includes an arc portion 301 and a straight portion 302. The arc portion 301 of each chain link 106 is engaged with the sprocket 105. The straight portions 302 of two chain links 106 are parallel, and the cutters 108 on the straight portions 302 on the side where the two chain links 106 are close to each other are opposed to each other. With the drive of the sprocket 105, the chain link 106 rotates, and the chain will drive the cutter 108 thereon when rotating. When the cutter 108 moves to the arc portion 301 of the chain link 106 at the front end of the vehicle frame 101, the arc-shaped groove 201 of the cutter 108 captures the mulberry branches. When the cutter 108 moves to the straight portion 302 of the chain link 106, the cutter 108 cuts the mulberry leaves on the mulberry branches under the drive of the chain link 106. When the cutter 108 moves with the chain link 106 to the arc portion 301 of the chain link 106 at the rear end of the vehicle frame 101, the arc-shaped groove 201 of the cutter 108 releases the mulberry branches, so as to realize timely release of the mulberry branches after the mulberry leaves on the mulberry branches are cut, thereby further preventing the mulberry branches from being damaged.

[0041] As a preferred solution, as Figure 1 , Figure 3 and Figure 6As shown in the figure, the two gathering components 103 have the same structure, each including a reel 401 and a second transmission shaft 402. The reels 401 of the two gathering components 103 are both horizontally arranged at the front end of the vehicle frame 101. The reel 401 is connected to the second transmission shaft 402. The second transmission shaft 402 is vertically arranged and rotatably connected to the vehicle frame 101. The power device 107 is connected to the second transmission shaft 402. A plurality of arc-shaped reel blades 403 are provided on the outer edge of the reel 401. The power device 107 drives the two reels 401 to rotate in opposite directions. Under the action of the plurality of arc-shaped reel blades 403 on the two reels 401, the mulberry branches at the front end of the vehicle frame 101 can be gathered between the chain loops 106 of the two cutting components. The main function of the gathering component 103 is to gather the mulberry branches. Since the mulberry branches are relatively tough and soft, in order to prevent the reel 401 from damaging the mulberry branches, the material of the above-mentioned reel 401 is selected as a flexible material such as high molecular polyethylene. A fixed support plate is provided at the lower end of the second transmission shaft 402. The fixed support plate is used to apply a vertical supporting force to the second transmission shaft 402. The fixed support plate requires a relatively large stiffness, and the material is low-alloy high-strength steel. End covers are provided at both the upper and lower ends of the second transmission shaft 402. During operation, the power device 107 drives the second transmission shaft 402 to rotate, the second transmission shaft 402 drives the reel 401 to rotate, and the reel 401 drives the plurality of arc-shaped reel blades 403 on its outer edge to rotate. Since the second transmission shaft 402 is vertically arranged, therefore, the plurality of arc-shaped reel blades 403 rotate in the horizontal plane. The two reels 401 rotating in opposite directions can gather the mulberry branches between the chain loops 106 of the two cutting components through the plurality of arc-shaped reel blades 403 on their respective outer edges, so that the mulberry branches can be smoothly caught in the annular cutting edge 109 formed by the two opposed cutting tools 108, ensuring the normal cutting of the mulberry leaves on the mulberry branches.

[0042] As a preferred solution, as Figure 1 and Figure 4As shown in the figure, the collection mechanism 102 includes two groups of conveyor belts 501 and a collection box 502. The two groups of conveyor belts 501 and the collection box 502 are symmetrically arranged on the left and right sides of the vehicle frame 101. The two conveyor belts 501 are arranged in a V-shaped structure. One end of each conveyor belt 501 is arranged at the lower end of a chain loop 106, and the other end of each conveyor belt 501 is arranged at the top of a collection box 502. The conveyor belt 501 is used to convey the mulberry leaves cut by the annular cutting edge 109 into the collection box 502. After the cutter 108 cuts the mulberry leaves on the mulberry twig, the mulberry leaves fall onto the conveyor belt 501. Through the transmission of the conveyor belt 501, the mulberry leaves are conveyed to the top of the collection box 502 and are conveyed into the collection box 502 through the top opening of the collection box 502 to complete the collection of the mulberry leaves. Since the two conveyor belts 501 are arranged in a V-shaped structure, no matter whether the mulberry leaves cut by the cutter 108 slide to the left side or the right side of the vehicle frame 101, they can be conveyed into the collection box 502, thus preventing the cut mulberry leaves from scattering to the ground.

[0043] As a preferred solution, as Figure 1 and Figure 4 shown in the figure, multiple partitions 6 are provided on each conveyor belt 501. The length direction of each partition 6 is the same as the length direction of the vehicle frame 101. The partition 6 is used to prevent the mulberry leaves from sliding off the conveyor belt 501. The conveyor belt 501 is a U-shaped conveyor belt 501. By providing multiple partitions 6 on the conveyor belt 501, since the length direction of each partition 6 is the same as the length direction of the vehicle frame 101, there is a certain angle with the conveying direction of the conveyor belt 501. Therefore, the mulberry leaves that slide onto the conveyor belt 501 move towards the top of the collection box 502 under the drive of the conveyor belt 501. During this process, the partition 6 can effectively prevent the mulberry leaves from sliding off the conveyor belt 501 and ensure that the mulberry leaves can be smoothly conveyed into the collection box 502.

[0044] As a preferred solution, as Figure 5 and Figure 6As shown in the figure, a transmission mechanism is further included. The transmission mechanism includes a main transmission shaft 701 and a plurality of pulley mechanisms. The main transmission shaft 701 is horizontally arranged and rotatably connected to the vehicle frame 101. The main transmission shaft 701 is connected to the power device 107 through a pulley mechanism. The second transmission shaft 402 is engaged with a horizontal gear shaft 702, and the horizontal gear shaft 702 is connected to the main transmission shaft 701 through a pulley mechanism. The transmission belt is connected to the main transmission shaft 701 through a pulley mechanism. The power transmission device drives the main transmission shaft 701 to rotate. The main transmission shaft 701 drives the first transmission shaft 104 to rotate through a pulley mechanism, thereby driving the sprocket 105 to rotate to drive the chain ring 106 to rotate. At the same time, the main transmission shaft 701 drives the horizontal gear shaft 702 to rotate through a pulley mechanism. The horizontal gear shaft 702 drives the second transmission shaft 402 to rotate through bevel gears, thereby driving the reel 401 to rotate. The main transmission shaft 701 also drives the conveyor belt 501 to rotate through a pulley mechanism to convey the mulberry leaves thereon. The material of the main transmission shaft 701 is 45, 46, 60 high-quality alloy steel, and it is hollow inside. The belts of the above pulley mechanisms are all made of flexible materials such as rubber, PVC, PU, steel wire core or fabric core, and can withstand high-speed transmission.

[0045] As a preferred solution, as Figure 1 and Figure 5 shown in the figure, a central vertical plate 801 is provided on the vehicle frame 101. An L-shaped handle 802 is provided on each side of the central vertical plate 801. The two L-shaped handles 802 are symmetrically arranged on both sides of the central vertical plate 801. One end of the L-shaped handle 802 is connected to the L-shaped handle 802, and the other end of the L-shaped handle 802 is provided with anti-slip lines. When the user drives the vehicle frame 101 to move, the user can hold the anti-slip line part of the L-shaped handle 802 and then apply a thrust to the central vertical plate 801 through the L-shaped handle 802 to drive the vehicle frame 101 to move.

[0046] As a preferred solution, as Figure 1 and Figure 5As shown in the figure, a traveling mechanism is provided on the frame 101. The traveling mechanism includes a front left wheel 901, a front right wheel 902, a central left wheel 903, and a central right wheel 904. The front left wheel 901, the front right wheel 902, the central left wheel 903, and the central right wheel 904 are all connected to the frame 101, and the tire sizes of the front left wheel 901, the front right wheel 902, the central left wheel 903, and the central right wheel 904 have multiple specifications. When a user applies a thrust to the frame 101, the thrust of the frame 101 drives the front left wheel 901, the front right wheel 902, the central left wheel 903, and the central right wheel 904 to roll on the ground, thereby realizing the movement of the frame 101. And by adjusting the tire sizes of the front left wheel 901, the front right wheel 902, the central left wheel 903, and the central right wheel 904, the height and attitude of the frame 101 can be adjusted, so as to adapt to different terrains and mulberry branches of different heights, thereby improving the applicability of the entire harvester.

[0047] As a preferred solution, as Figure 3 shown in the figure, wherein, the multiple arc-shaped reel plates 403 are respectively arranged at the upper end and the lower end of the reel 401, and the arc-shaped reel plates 403 at the upper end of the reel 401 are staggered from the arc-shaped reel plates 403 at the lower end of the reel 401. By arranging the multiple arc-shaped reel plates 403 at the upper end and the lower end of the reel 401, and staggering the arc-shaped reel plates 403 at the upper end of the reel 401 from the arc-shaped reel plates 403 at the lower end of the reel 401, the mulberry branches can be more efficiently gathered, thereby improving the efficiency of mulberry leaf harvesting.

[0048] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
