[0002] As the main food for silkworms, the efficiency of mulberry leaf picking is directly related to the healthy development of the sericulture industry. With the reduction of rural labor, the sericulture industry faces new challenges, and improving the efficiency of mulberry leaf picking has become a problem to be solved urgently. However, there are some shortcomings in the existing mulberry leaf picking methods, such as the small area of ​​mulberry leaf picking cannot use large-scale mechanized picking equipment, and can only be picked manually, and the manual picking efficiency is low. At present, there are cutting tools on the market that are worn on the fingers, and silkworm farmers can only pick from mulberry trees one by one, which is quite inefficient. Even if silkworm farmers use the method of wiping from the top to the bottom of the branch to increase the picking speed, they can pick a whole branch of mulberry leaves at a time, but this picking method is extremely harmful to mulberry buds and mulberry branches, which seriously affects the yield of mulberry leaves and the health of mulberry trees.

[0003] Therefore, how to provide a simple, fast and mulberry leaf picking tool that can protect mulberry trees is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0006] The body has a bottom wall with a transverse channel, and a side wall with a side wall channel connected to the transverse channel, and the transverse channel and the side wall channel form a mulberry branch channel;

[0007] An operating part connected to the outer wall of the body;

[0008] The combined knife comprises a movable blade and a fixed blade. The fixed blade is fixed to the inner side of the bottom wall of the body and arranged around one end of the transverse channel. The movable blade is movably connected to the inner side of the bottom wall of the body and can block the transverse channel and enclose with the fixed blade to form a picking area.

[0009] According to the tool of the present invention, the body is a cup body or a cylinder body, and the corresponding side wall channels are arranged obliquely or vertically.

[0010] According to the tool of the present invention, the operating part is a handle, and the inner side of the handle is provided with a groove for accommodating fingers.

[0011] According to the tool of the present invention, the operating part is a connecting rod, and the connecting rod is a telescopic rod that can be connected to the collecting and transferring device.

[0012] According to the tool of the present invention, one end of the transverse channel is an arc-shaped hole structure, and the fixed blade is arranged around the arc-shaped hole structure and tilted upward.

[0013] According to the tool of the present invention, the movable blade is close to one end of the fixed blade and is rotatably connected to the bottom of the body through a rotating part, and a baffle for stopping the movable blade is fixed to the other end close to the fixed blade.

[0014] According to the tool of the present invention, the upper cutting edge of the movable blade is arranged obliquely, and a stop plate is provided at the bottom thereof away from the side of the transverse channel.

[0015] According to the tool of the present invention, the rotating part comprises:

[0016] A rotating body, the top of which is connected to the movable blade as a whole;

[0017] A bearing seat, the outer shell of which is fixed to the bottom of the body and the interior of which is rotatably connected to the rotating body;

[0018] A pull rod, wherein the middle part is connected to the lower part of the rotating body, a pull rope is connected to one end of the pull rod, and the end of the pull rope away from the pull rod extends from the bottom of the body, gradually extends along the side wall of the body to the vicinity of the operating part, and is connected to a pull ring;

[0019] The torsion spring is sleeved on the rotating body and located above the bearing seat, one end of which is hooked in the opening at the bottom of the body, and the other end is hung on the other end of the pull rod.

[0020] According to the tool of the present invention, the pull rope is guided by a rope guide buckle fixed on the body.

[0021] According to the tool of the present invention, the bottom of the body has a receiving cavity, and the receiving cavity is formed by clamping the bottom cover with the bottom of the body.

[0022] It can be seen from the above technical solution that compared with the prior art, the present invention has the following beneficial effects:

[0023] The present invention uses a bottom opening design to allow mulberry branches to quickly enter the center of the picking cup, and as the picking cup moves from the bottom of the mulberry branch to the top, the blade quickly cuts off the petiole of the mulberry leaves. All the cut mulberry leaves are collected in the cup, which is convenient for rapid transfer to a mulberry leaf collection and transfer device such as a backpack, thereby significantly improving the picking efficiency.

[0024] The blade of the present invention is designed to be inclined 10-15 degrees to the periphery, effectively avoiding damage to mulberry branches and mulberry buds during cutting. This design ensures the healthy growth of mulberry branches, reduces tree damage caused by picking, and is conducive to long-term planting and high yield of mulberry trees.

[0025] Since the blades will not damage the mulberry branches and mulberry buds during work, the quality of the collected mulberry leaves is guaranteed. The burrs and damages that may be caused by the traditional manual picking method are avoided, making the mulberry leaves more complete and clean, which is conducive to the subsequent silkworm breeding process.

[0026] The invention reduces the cumbersome steps of manual operation. Workers only need to simply operate the operating part and the pull ring to complete the picking, which greatly reduces the labor intensity and improves the work efficiency. This is particularly important in rural areas where labor is increasingly scarce.

[0027] The invention not only improves the picking efficiency and quality of mulberry leaves, but also reduces the damage to mulberry trees, thus contributing to the healthy development of the sericulture industry. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Since it is impossible to use large-scale mechanized picking equipment to pick mulberry leaves from a small area, they can only be picked manually, which is inefficient. Currently, there are cutting tools that fit on the fingers on the market, and silkworm farmers can only cut and pick mulberry leaves from the mulberry trees one by one, which is quite inefficient. Even if silkworm farmers use the method of wiping from the top of the branch to the bottom to increase the picking speed, they can pick a whole branch of mulberry leaves at a time, but this picking method is extremely harmful to mulberry buds and branches, seriously affecting the yield of mulberry leaves and the health of mulberry trees.

[0041] In view of this, the technical solution of the present invention is a simple and fast mulberry leaf picking tool, comprising:

[0042] The body 10 has a bottom wall with a transverse channel 11, and a side wall channel 12 connected to the transverse channel 11 on its side wall, and the transverse channel 11 and the side wall channel 12 form a mulberry branch inlet channel;

[0043] An operating portion 20 connected to the outer wall of the body 10;

[0044] The combined knife comprises a movable blade 30 and a fixed blade 40. The fixed blade 40 is fixed to the inner side of the bottom wall of the main body 10 and is arranged around one end of the transverse channel 11. The movable blade 30 is movably connected to the inner side of the bottom wall of the main body 10, and can block the transverse channel 11 and enclose with the fixed blade 40 to form a picking area.

[0045] In one embodiment of the present invention, see the attached Figure 1-4 The main body 10 is a cup body, and the corresponding side wall channel 12 is arranged obliquely. The operating part 20 is a handle, and the inner side of the handle has a groove for accommodating fingers. The groove can accommodate four fingers, which is convenient for one-handed holding and easy operation.

[0046] The body 10 may also be a cylinder, and the corresponding side wall channels 12 are arranged vertically.

[0047] In this embodiment, one end of the transverse channel 11 is an arc-shaped hole structure, and the fixed blade 40 is arranged around the arc-shaped hole structure and tilted upward. The tilt angle can be 10-15 degrees to prevent damage to the mulberry branches.

[0048] Advantageously, the movable blade 30 is rotatably connected to the bottom of the body 10 through a rotating part 50 at one end close to the fixed blade 40, and a baffle 31 is fixed at the other end close to the fixed blade 40 to stop the movable blade 30, so as to prevent the movable blade 30 from damaging the mulberry branch.

[0049] More advantageously, the upper blade edge of the moving blade 30 is arranged obliquely, and a stop plate 32 is provided at the bottom thereof away from the transverse channel 11 to prevent damage to the bottom wall of the body during the opening process of the moving blade 30. The stop plate 32 has a thickness of about 1 mm.

[0050] In another embodiment of the present invention, see the attached Figure 8 and 9 The main body 10 is a cup body, and the corresponding side wall channel 12 is arranged obliquely. The main body 10 can also be a cylinder, and the corresponding side wall channel 12 is arranged vertically. The operating part 20 is a connecting rod, and the connecting rod is a telescopic rod that can be connected to the collection and transfer device.

[0051] Similarly, in this embodiment, one end of the transverse channel 11 is an arc-shaped hole structure, and the fixed blade 40 is arranged around the arc-shaped hole structure and tilted upward. The tilt angle can be 10-15 degrees to prevent damage to the mulberry branches.

[0052] Advantageously, the movable blade 30 is rotatably connected to the bottom of the body 10 through a rotating portion 50 near one end of the fixed blade 40, and a baffle 31 is fixed near the other end of the fixed blade 40 to stop the movable blade 30, so as to prevent the movable blade 30 from closing too much and damaging the mulberry branch.

[0053] More advantageously, the upper blade edge of the moving blade 30 is arranged obliquely, and a stop plate 32 is provided at the bottom thereof away from the transverse channel 11 to prevent damage to the bottom wall of the body during the opening process of the moving blade 30. The stop plate 32 has a thickness of about 1 mm.

[0054] In the above embodiments, see the attached Figure 5-7 , the rotating part 50 includes:

[0055] The rotating body 51 has a top connected to the movable blade 30 as a whole;

[0056] A bearing seat 52, the outer shell of which is fixed to the bottom of the body 10, and the interior of which is rotatably connected to the rotating body 51;

[0057] A pull rod 53, the middle of which is connected to the lower part of the rotating body 51, and a pull rope 60 is connected to one end of the pull rod 53. The end of the pull rope 60 away from the pull rod 53 extends from the bottom of the body 10, gradually extends along the side wall of the body 10 to the vicinity of the operating part 20, and is connected to a pull ring 61;

[0058] The torsion spring 54 is sleeved on the rotating body 51 and located above the bearing seat 52 , with one end of the torsion spring 54 hooked in the opening at the bottom of the body 10 and the other end of the torsion spring 54 being connected to the other end of the pull rod 53 .

[0059] The movable blade 30 and the pull rod 53 are arranged at 90 degrees.

[0060] In the embodiment using the telescopic rod, the pull cord 60 can be inserted into the interior of the telescopic rod to prevent the pull cord from being too long outside and affecting the operation.

[0061] In the present invention, unless otherwise clearly stipulated and limited, the terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0062] In the present invention, the stop plate 32 of the movable blade 30 is parallel to the inner side of the bottom wall of the main body and may have a small gap, but the torsion spring 54 and the like should not leak out from the connection between the rotating main body 51 and the bottom wall of the cup body to prevent mulberry leaves from entering the torsion spring 54 and affecting the normal operation of the movable blade 30.

[0063] When a finger pulls the pull ring 61, the pull rope 60 is pulled and stretched, thereby driving the pull rod 53, so that the rotating body 51 rotates around the bearing, opening the movable blade 30, and the movable blade 30 is away from the transverse channel 11. The transverse channel 11 is opened, and the mulberry branches can enter at this time. After the mulberry branches enter, the pull ring is released, and the movable blade rotates toward the baffle 31 under the torsional force of the torsion spring 54, and the baffle 31 stops, and the mulberry leaves can be picked at this time.

[0064] Advantageously, the draw cord 60 may be guided by a cord guide buckle 62 fixed to the body 10 .

[0065] More advantageously, the bottom of the main body 10 has a receiving cavity, which is formed by snapping the bottom cover 13 with the bottom of the main body 10 to receive the bottom of the rotating body 51, the pull rod 53 and the bottom guide rope buckle 62.

[0066] When in use, tighten the draw rope, the movable blade opens the mulberry branch entrance channel, the mulberry branches enter the arc-shaped hole structure in the middle of the main body through the mulberry branch entrance channel and gather, then relax the pull ring, the movable blade closes the mulberry branch entrance channel, and the handheld main body is quickly moved from the bottom of the mulberry branch to the top of the mulberry branch. The mulberry branch quickly cuts off the mulberry leaf petiole under the action of the movable blade and the arc-shaped fixed blade. All the cut mulberry leaves are collected in the cup and can then be quickly transferred to a mulberry leaf transfer device such as a backpack.

[0067] The movable blade and the fixed blade of the present invention are both inclined toward the periphery by 10-15 degrees, which effectively prevents the blades from damaging the mulberry branches and mulberry buds during operation. A sufficiently large arc-shaped hole structure is left at the center of the bottom of the present invention, which can ensure that the mulberry branches can pass smoothly while ensuring that the 1-3 tender leaves at the top of the mulberry branches are not cut by the blades.

[0068] The movable blade designed in the present invention is opened by pulling a pull ring at the operating part. When the mulberry branch enters the central arc-shaped hole structure position, the pull ring is released, and the blade closes to seal the opening position, ensuring that the mulberry branch is completely surrounded by the blade, thereby improving the picking efficiency.
