[0023] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] As shown in Figure 1, the utility model discloses a sickle for cutting tobacco stems and tobacco leaves, which comprises a knife sleeve 3 and at least two cutting knives. Figures 1-4 The cutting knives are accommodated in the knife sleeve 3, which can protect the cutting knives. Two cutting knives are arranged in the knife sleeve 3, so that a new cutting knife can be immediately replaced when one of the cutting knives is damaged, thereby avoiding time waste in replacement and improving harvesting efficiency.

[0025] In the embodiment, the cutting knives comprise a first curved knife 1 and a second curved knife 2. The first curved knife 1 and the second curved knife 2 are in the shape of a sickle. Handles 5 are arranged on the first curved knife 1 and the second curved knife 2. The handles 5 are provided with through holes matched with the shaft 4. The first curved knife 1 and the second curved knife 2 are rotationally matched with the shaft 4 through the through holes. The cutting edge of the first curved knife 1 is in the shape of a sawtooth. The cutting knife provided with the sawtooth-shaped cutting edge can be used for cutting tobacco stems. In combination with ordinary cutting knives, the corresponding cutting knife can be selected during cutting, thereby improving harvesting efficiency. The handles 5 are in the shape of an arc, which is convenient for holding and cutting. Circular rings 9 are arranged on the inner sides of the first curved knife 1 and the second curved knife 2. The circular rings 9 are used for pulling the cutting knives out of the knife sleeve 3, thereby avoiding direct contact with the cutting edges. The circular rings 9 are arranged on the end portions of the cutting edges close to one side of the handles 5.

[0026] In this embodiment, the blade sheath 3 includes two symmetrically arranged limiting plates 6, connected by a connecting plate 7 to form a U-shaped plate. The cutter is housed within the U-shaped plate. A handle 8 is provided on the limiting plate 6, and a rotating shaft 4 is connected to the handle 8 on the side away from the limiting plate 6. The limiting plate 6 and the handle 8 are integral plates, and the integral plate has a groove that mates with the pulling member. The groove facilitates the removal of the cutter from the blade sheath 3.

[0027] In this embodiment, the blade sleeve 3 is provided with a limiting rod 10 for restricting the cutter. The limiting rod 10 is a U-shaped rod, which cooperates with the upper limit hole of the blade sleeve 3 and the cutter. When the cutter is stored in the blade sleeve 3, the limiting rod 10 passes through the blade sleeve 3 and the cutter, which can restrict the cutter from rotating around the shaft 4, thereby preventing the cutter from sliding out of the blade sleeve 3.

[0028] This device is movably connected to the rotating shaft 4 via a serrated sickle handle 8. Pulling the serrated sickle circular ring 9 allows the serrated sickle to be stored in and removed from its sheath 3. The serrated sickle handle 8 is streamlined to reduce hand fatigue, and pulling the handle 8 allows for cutting the main stem of the tobacco plant. The ordinary sickle handle 8 is movably connected to the rotating shaft 4. Pulling the ordinary sickle circular ring 9 allows the ordinary sickle to be stored in and removed from its sheath 3. The ordinary sickle handle 8 is streamlined to reduce hand fatigue, and pulling the handle 8 allows for cutting the leaves of the tobacco plant. The sheath 3 is fixedly connected to the rotating shaft 4 and is used to store both the serrated sickle and the ordinary sickle.

[0029] like Figure 5 As shown in Embodiment 2, a sickle for cutting tobacco stems and leaves has a U-shaped buckle plate 11 on the handle 8. The U-shaped buckle plate 11 on the handle 8 can restrict the handle 5, thereby achieving protective limiting of the cutter.

[0030] All other structures are the same as in Example 1.

[0031] like Figures 1-3 As shown in Embodiment 1, a sickle for cutting tobacco stems and leaves includes a sheath and at least two cutting blades. The sheath has a pivot, and the cutting blades are rotatably mounted on the sheath via the pivot. The two cutting blades are a serrated blade and a standard blade, respectively.

[0032] The sheath has a hollow center and is connected by an arc-shaped baffle at the top and bottom. The upper and lower handles of the sheath also have a hollow center to reduce resistance when the serrated sickle and the ordinary sickle are turned.

[0033] The serrated sickle grip, the regular sickle grip, and the scabbard grip are all connected by a rotating shaft.

[0034] When cutting the main stem of tobacco plant, the serrated sickle circular ring is pulled to take out the serrated sickle from the sheath, the serrated sickle handle is held, and the main stem of tobacco plant is cut from outside to inside, so that the cutting process is completed, manual upper leaf band stem cutting is facilitated, manual efficiency is improved, and after ending, the serrated sickle circular ring is pulled to be taken back to the sheath; when cutting the tobacco plant leaves, the common sickle circular ring is pulled to take out the common sickle from the sheath, the common sickle handle is held, and the tobacco plant leaves are cut from outside to inside, so that the cutting process is completed, and after ending, the common sickle circular ring is pulled to be taken back to the sheath.

[0035] The above merely describes preferred embodiments of the utility model and is not intended to limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
