Technical Field
[0001] This utility model relates to an outdoor sugarcane leaf peeling tool for manual and efficient peeling, specifically an adjustable-height sugarcane leaf peeler. Background Technology
[0002] After sugarcane reaches its elongation stage, the stalk gradually grows taller, and new leaves continuously grow and expand at the top, increasing in leaf area and shading the gaps between rows, achieving "row closure." Leaves growing in the middle and lower parts of the sugarcane stalk, due to the shading of the functional leaves at the top of the plant, lack direct sunlight and cannot produce nutrients through photosynthesis. Instead, they consume some of the nutrients produced by the plant, gradually aging and turning yellow. Therefore, it is essential to remove leaves from the sugarcane after the rows have closed. Removing leaves from sugarcane has the following benefits: 1. Promotes growth. The fully expanded leaves in the middle and lower parts of the sugarcane stalk turn yellow and gradually lose their photosynthetic capacity, instead consuming plant nutrients and reducing the yield and quality of the leaves. Timely removal of these old leaves can reduce nutrient loss and promote sugarcane growth and sugar accumulation. 2. Improves ventilation and light penetration. Sugarcane plants are relatively tall with dense leaves. If leaves are not removed, it will lead to poor ventilation and increased humidity in the field, making it easier for pests and diseases (such as sugarcane borers and smut). Removing leaves enhances air circulation in the field, reduces humidity, and decreases the probability of pests and diseases. 3. Prevents pests and diseases. Dead and diseased leaves are hiding and overwintering sites for pests (sugarcane borers, aphids) and hosts of bacterial and viral diseases. Removing old leaves reduces the breeding of insect eggs and pathogens, lowering the risk of pests and diseases. 4. Facilitates field management. After leaf removal, the sugarcane stalks are exposed, which is beneficial for subsequent fertilization, spraying, irrigation, and other agricultural operations, and also facilitates direct observation of sugarcane growth. 5. Increases sugar accumulation. Appropriate leaf removal optimizes the overall photosynthetic efficiency of the sugarcane plant, allowing the retained top functional leaves to receive more sunlight, promoting sugar synthesis and accumulation, and increasing sugarcane yield and quality. 6. Reduces ineffective tillers. Leaf removal inhibits ineffective tillers at the base of the roots and ineffective lateral buds on the stem, preventing nutrient loss, increasing stem diameter, and improving sugar content and yield. Therefore, leaf removal is essential after the sugarcane has elongated.
[0003] Currently, manual leaf stripping is generally done using sickles. A typical sickle consists of a single-edged blade and a single handle. Since sugarcane leaves grow scattered on cylindrical stalks, the single-edged structure of a standard sickle cannot remove all the leaves in one go. It requires repeated, manual downward slashing from different angles to completely remove excess leaves and side shoots. Prolonged use of a sickle for leaf stripping easily leads to arm soreness, low efficiency, and high labor intensity. Furthermore, the handle length of a standard sickle is approximately 40-50cm, and considering the user's height, it can generally only strip leaves from sugarcane stalks approximately 2.0-2.5m high. When sugarcane is fully grown and has reached its peak length, it is generally over 3m. For an average person of normal height, without the aid of tools (such as stairs), it is difficult to completely strip leaves from the closed sugarcane stalks due to insufficient height. Therefore, there is an urgent need in production for a sugarcane leaf stripping tool that can adapt to various sugarcane stalk heights, is convenient, and can improve labor efficiency. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide an adjustable height sugarcane high-efficiency leaf peeler that can be used to adapt to various sugarcane plant heights and is lightweight and efficient in peeling leaves.
[0005] The present invention solves the above-mentioned technical problems with the following technical solution:
[0006] This utility model discloses an adjustable-height, high-efficiency sugarcane leaf peeler, comprising a telescopic support rod, a fixed sleeve, and a composite cutting head. One end of the fixed sleeve is fixedly connected to the composite cutting head, and the other end is connected to the telescopic support rod. The composite cutting head includes a U-shaped ring cutter, which consists of a hook with an upward-facing opening in a U-shape. Its bottom is connected to the fixed sleeve. The upper opening of the hook is wider than the bottom opening. The hook can adapt to different sugarcane stalks. The blade on the side of the hook is parallel to the length direction of the sugarcane and is set downwards.
[0007] The bottom of the knife hook described in this utility model is welded or bolted to the fixed sleeve.
[0008] The composite cutting head of this utility model also includes a crescent-shaped cutter, which is fixed to the upper part of the fixed sleeve. The blade of the crescent-shaped cutter is set downward and parallel to the length direction of the sugarcane, and is located on the opposite side of the U-shaped ring cutter.
[0009] The telescopic support rod of this utility model includes an upper support rod, a lower support rod, and a fastening ring. The upper support rod and the lower support rod are sleeved together, and the fastening ring is set on the top of the lower support rod and can lock and fix the upper support rod and the lower support rod.
[0010] The inner wall of the fixed sleeve of this utility model is provided with an internal thread, and the top of the upper support rod of the telescopic support rod is provided with an external thread that matches the internal thread of the fixed sleeve.
[0011] This utility model of an adjustable-height, high-efficiency sugarcane leaf peeler has the following beneficial effects:
[0012] This invention utilizes a simple, practically designed composite cutting head that effectively addresses various situations encountered during sugarcane leaf removal, significantly improving removal efficiency. The U-shaped ring-cutting blade effectively wraps around three-quarters of the sugarcane stalk, allowing for quick and efficient cutting of the leaves to be removed. This effectively reduces the frequency of manual leaf removal, increasing work efficiency and reducing labor intensity. Furthermore, the U-shaped ring-cutting blade's wider-than-bottom design adapts to different sugarcane stalk diameters, broadening its applicability and increasing removal efficiency. It can remove all leaves in one pass, saving time and effort. Additionally, the composite cutting head includes a crescent-shaped blade to handle situations where other U-shaped ring-cutting blades cannot achieve the desired cuts.
[0013] The telescopic support rod used in this invention can be flexibly adjusted in length according to the actual height of the sugarcane plant. It is suitable for peeling leaves from sugarcane stalks at different growth stages, and is especially suitable for peeling leaves from sugarcane plants taller than 3m after the sugarcane canopy has closed. It can reduce labor intensity and improve work efficiency. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings.
[0019] like Figure 1-3As shown, this utility model of an adjustable-height, high-efficiency sugarcane leaf peeler includes a telescopic support rod 2, a fixed sleeve 6, and a composite cutting head 1. The composite cutting head 1 is fixed to one end of the fixed sleeve 6, and the other end of the fixed sleeve 6 is connected to the telescopic support rod 2. The composite cutting head 1 includes a U-shaped ring cutter 3, which consists of a U-shaped hook 5 with its opening facing upwards. The bottom of the hook 5 is welded or bolted to the fixed sleeve 6. The upper opening of the hook 5 is wider than the bottom opening. The hook 5 is used to clamp the sugarcane stalk and can adapt to different sugarcane stalk sizes. The blade on the side of the hook 5 is parallel to the length direction of the sugarcane and is set downwards.
[0020] The composite cutting head 1 also includes a crescent-shaped cutter 4, which is fixed to the upper part of the fixed sleeve 6 by welding. The blade of the crescent-shaped cutter 4 is set downward and parallel to the length direction of the sugarcane, and is located on the opposite side of the U-shaped ring cutter 3.
[0021] The composite cutting head 1 used in this invention can handle various situations during leaf peeling.
[0022] The telescopic support rod 2 of this utility model includes an upper support rod 8, a lower support rod 10, and a fastening ring 11. The lower end of the upper support rod 8 is sleeved with the lower support rod 10 and locked in place by the fastening ring 11 installed on the top of the lower support rod 10. The upper end of the upper support rod 8 is threadedly connected to the fixing sleeve 6. The inner wall of the fixing sleeve 6 is provided with an internal thread 7, and the top of the upper support rod 8 is provided with an external thread 9 that matches the internal thread 7 and can be screwed on. The external thread 9 and the internal thread 7 are fixed and loosened by rotating screwing, which can realize the fixing and disassembly of the composite cutting head 1 and the telescopic support rod 2. The upper support rod 8 can move up and down freely as needed, which makes it convenient for users to adjust the overall length of the telescopic support rod 2 according to the height of the sugarcane plant to be peeled.
[0023] Once the overall length of the telescopic support rod 2 is determined, the relative positions of the upper support rod 8 and the lower support rod 10 are adjusted and locked in place by the fastening ring 11, so that the overall length of the telescopic support rod matches the actual height of the peeled sugarcane.
[0024] When using this leaf peeler, first assemble all components, then use the leaf peeler to peel sugarcane leaves. The user pulls the upper support rod 8 from the lower support rod 10 of the telescopic support rod 2, adjusts the relative position of the two according to the height of the sugarcane plant to be peeled and the position of the top leaf to be retained, and locks the relative length of the telescopic support rod 2 in place using the fastening ring 11. When not in use, the telescopic support rod 2 can be loosened by unscrewing the fastening ring 11, allowing the upper support rod 8 to be inserted into the lower support rod 10, making it easy to carry and saving storage space.
[0025] In practical use, the user firmly grips the telescopic support rod 2 with both hands, places the U-shaped ring-cutting blade 3 against the sugarcane stalk where leaf removal is needed, and drags the telescopic support rod 2 downwards. The U-shaped ring-cutting blade 3, fixed to the top of the telescopic support rod 2, moves downwards along the sugarcane stalk. The slightly expanded opening of the U-shaped ring-cutting blade 3 can accommodate sugarcane stalks of different diameters. The blade of the U-shaped ring-cutting blade 3 cuts along the base of the leaf where it meets the stalk, completing the cutting of leaves in 3 / 4 of the entire stalk. The remaining 1 / 4 of the stalk is then cut in the same manner, completing the leaf removal process once more. This process, involving only two steps, removes the excess leaves except for the reserved top leaves, avoiding the need for repeated arm swings required by traditional sickles, thus reducing labor intensity and improving efficiency. Simultaneously, the crescent-shaped cutting blade 4 of the composite cutting head 1 can handle the cutting and removal of harder leaves and other harder lateral buds encountered during production, expanding the application scope of this invention and achieving multi-functional effects. The telescopic support rod 2 used in this utility model leaf peeler can avoid the problem that the sugarcane stalk is too tall and exceeds the total height of the arm and sickle, making it impossible to complete the leaf peeling operation. Users can adjust the length of the telescopic support rod 2 to adapt to the leaf peeling of sugarcane of various plant heights, thereby improving the leaf peeling production efficiency and reducing labor intensity.
