Description
Technical Field
[0001] This application relates to the field of cutting line technology, and in particular to a sharp and durable plant cutting line. Background Technology
[0002] Currently, grass cutting lines, commonly known as grass cutting ropes, are used as cutting lines in equipment such as lawnmowers, brush cutters, and edge trimmers. They are mainly used for cutting weeds, shrubs, or other soft plants.
[0003] In the prior art, the cutting line has several straight or flat teeth along its length. During the cutting process, the cutting machine and the cutting line work together to drive the straight or flat teeth on the outside of the cutting line to rotate and come into contact with the plant, thereby cutting the plant.
[0004] Regarding the aforementioned technologies, when the plant contacts the flat or straight teeth, the contact area between the plant and the cutting line is large, resulting in poor sawing effect of the cutting line on the plant. Furthermore, due to the gaps between the straight or flat teeth, when the cutting line cuts the plant, some of the plant will be located between two adjacent straight teeth and directly contact the cutting line. This part of the plant has low cutting efficiency, and during long-term rotation, this part of the plant comes into contact with the cutting line and wears down the cutting line, leading to breakage of the cutting line and low plant cutting efficiency. Utility Model Content
[0005] To improve the efficiency of plant cutting, this application provides a sharp and durable plant cutting wire.
[0006] This application provides a sharp and durable plant cutting wire, employing the following technical solution: A sharp and durable plant cutting wire includes a cutting strip, with several connecting blocks fixed circumferentially on the outer side of the cutting strip. The connecting blocks are arranged along the length of the cutting strip. Both the connecting blocks and the cutting strip are made of nylon material and are integrally formed. Several openings are opened along the thickness direction on the side of the connecting blocks away from the cutting strip. The openings are arranged along the length of the connecting blocks, and the width of the openings is smaller than the width of the connecting blocks. The connecting block between two adjacent openings is a cutting part. The side of the cutting part away from the cutting strip is toothed. A cutting element is provided inside the opening, and the cutting element cuts the plant inside the opening.
[0007] By adopting the above technical solution, when plants need to be cut, the two ends of the cutting strip along the length direction are connected to the cutting machine. The rotation of the cutting strip drives several connecting blocks to rotate. During cutting, the sharp teeth of the cutting part contact the plant and cut the plant. When the plant is located in the opening, since the width of the opening is smaller than the width of the connecting block, the plant wears on the connecting block. The cutting part in the opening cuts the plant, which improves the stability of the cutting strip and the cutting efficiency.
[0008] Optionally, there are four connecting blocks, arranged symmetrically in pairs.
[0009] By adopting the above technical solution, the symmetrical connecting blocks allow the cutting part to cut the plant more effectively, thus improving the cutting efficiency.
[0010] Optionally, the cutting section can be designed asymmetrically on both sides along the length of the cutting strip.
[0011] By adopting the above technical solution, the cutting part is asymmetrically arranged, so that the cutting part contacts the plant in an inclined manner and the plant slides on the surface of the cutting part to complete the cutting. This helps to reduce the impact force of the plant on the cutting part and further improves the stability of the cutting part during operation.
[0012] Optionally, the cutting portions of any two adjacent connecting blocks point in opposite directions and respectively point to both sides of the cutting strip along its length.
[0013] By adopting the above technical solution, when the cutting part cuts the plant, the plant slides on the surface of the cutting part and moves towards the opening. The cutting parts of two adjacent connecting blocks point in opposite directions, which helps to reduce the probability of the plant being located at the opening. This allows the plant to slide back and forth between the cutting parts of two adjacent connecting blocks, thereby completing the plant cutting operation and improving the stability of the cutting.
[0014] Optionally, the openings on two adjacent connecting blocks are alternately arranged, and the openings and cutting parts on two adjacent connecting blocks are directly opposite each other.
[0015] By adopting the above technical solution, since the plant part is relatively long, when part of the plant is located inside the opening, the plant will rotate with the connecting block during the rotation of the connecting block and become entangled in the cutting part, causing the cutting part to fail. When the cutting strip rotates, the plant will come into contact with the adjacent cutting part, thereby realizing the cutting operation of the plant, which helps to reduce the probability of the plant getting entangled on the surface of the connecting block.
[0016] Optionally, the cutting component includes a support block and two cutting blades. The support block is located inside the opening and is arranged along the length of the cutting strip. The support block is fixedly connected to the connecting block. The two cutting blades are fixedly connected to both sides of the support block along the width direction and are arranged along the length direction of the support block.
[0017] By adopting the above technical solution, when the plant is located inside the opening, the support block supports the two cutting blades, and the cutting blades cut the plant inside the opening, so that the plant can be cut in time, which helps to reduce the probability of the plant getting tangled in the cutting strip.
[0018] Optionally, a number of support plates are fixed on the outside of the cutting strip. Each support plate corresponds to a connecting block. The support plate is located between two adjacent connecting blocks and is set along the length of the cutting strip. Cutting plates are fixed on both sides of the upper end of the support plate near the connecting blocks. The side of the cutting plate away from the support plate is located between the support plate and the connecting block and is located on the side of the support plate away from the cutting strip.
[0019] By adopting the above technical solution, when the plant is located between the two connecting blocks, the cutting part cannot cut the plant. When the cutting part comes into contact with the plant, the overall strength of the plant is longer and the toughness of the plant is increased, which increases the difficulty of cutting. At this time, the support plate supports the two cutting plates, and the cutting plates cut the plant, thereby reducing the length of the plant and improving the cutting efficiency.
[0020] Optionally, a baffle is fixedly provided on the side of the lower end of the cutting plate away from the support plate. The baffle is arranged along the length of the cutting plate, and the lower end of the baffle is fixedly connected to the side of the connecting block near the cutting strip.
[0021] By adopting the above technical solution, the baffle seals the gap between the connecting block and the support plate, which helps to reduce the probability of plants being located between the support plate and the connecting block and improves the convenience of cleaning up plants in the cutting strip.
[0022] Optionally, there are four connecting blocks. The cutting parts of two opposite connecting blocks point in opposite directions and to both sides of the cutting strip along its length. The cutting parts are asymmetrically designed along the length of the cutting strip. The cutting parts of the other two connecting blocks are symmetrically designed along the length of the cutting strip. The openings of two adjacent connecting blocks are directly opposite the cutting parts.
[0023] By adopting the above technical solution, the asymmetrical design of the cutting part allows it to contact the plant at an angle, and the plant slides on the surface of the cutting part to complete the cutting. At this time, the plant is located inside the opening. When the plant contacts the adjacent connecting block, the cutting part cuts and guides the plant, causing it to slide to both sides along the length of the cutting strip. The cutting strip continues to rotate. When the plant contacts the next connecting block, it still contacts the side of the cutting part away from the cutting strip, allowing the cutting part to continue contacting the plant at an angle and complete the cutting. The two cutting parts point in opposite directions, causing the plant to move and cut repeatedly within a certain area, thus improving the cutting efficiency.
[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. When plants need to be cut, the two ends of the cutting bar along the length direction are connected to the cutting machine. The rotation of the cutting bar drives several connecting blocks to rotate. During cutting, the sharp teeth of the cutting part contact the plant and cut the plant. When the plant is inside the opening, since the width of the opening is smaller than the width of the connecting blocks, the plant wears on the connecting blocks. The cutting part inside the opening cuts the plant, which improves the stability of the cutting bar and the cutting efficiency. 2. The asymmetrical design of the cutting section allows it to contact the plant at an angle, and the plant to slide on the surface of the cutting section to complete the cut. This helps to reduce the impact force of the plant on the cutting section and further improves the stability of the cutting section during operation. 3. When the plant is located between two connecting blocks, the cutting part cannot cut the plant. When the cutting part comes into contact with the plant, the overall strength of the plant is longer and the toughness of the plant is increased, which increases the difficulty of cutting. At this time, the support plate supports the two cutting plates. When the plant is located between the two connecting blocks, the cutting plate cuts the plant, thereby reducing the length of the plant and improving the cutting efficiency.

[0030] The present application will be further described in detail below with reference to all the accompanying drawings.
[0031] This application discloses a sharp and durable plant cutting wire.
[0032] Example 1 Reference Figure 1A sharp and durable plant cutting wire includes a cutting strip 1. Several connecting blocks 11 are fixedly arranged circumferentially on the outer side of the cutting strip 1. The connecting blocks 11 are arranged along the length of the cutting strip 1. Both the connecting blocks 11 and the cutting strip 1 are made of nylon material and are integrally formed. When it is necessary to cut the plant, the two ends of the cutting strip 1 along the length direction are connected to the cutting machine. The rotation of the cutting strip 1 drives the several connecting blocks 11 to rotate.
[0033] Reference Figure 1 The connecting block 11 has several openings 111 along its thickness direction on the side away from the cutting strip 1. The openings 111 are arranged along the length direction of the connecting block 11. The width of the openings 111 is smaller than the width of the connecting block 11. The connecting block 11 between two adjacent openings 111 is a cutting part 112. The side of the cutting part 112 away from the cutting strip 1 is toothed. When cutting, the toothed end of the cutting part 112 contacts the plant and cuts the plant. When the plant is located in the opening 111, since the width of the opening 111 is smaller than the width of the connecting block 11, the plant wears on the connecting block 11, which helps to reduce the degree of wear of the plant on the cutting strip 1.
[0034] Reference Figure 1 There are four connecting blocks 11, arranged symmetrically in pairs. The symmetrical arrangement of the connecting blocks 11 allows the cutting part 112 to cut the plant more effectively, improving cutting efficiency. The cutting part 112 is asymmetrically designed on both sides along the length of the cutting strip 1. This asymmetrical arrangement allows the cutting part 112 to contact the plant at an angle, and the plant to slide on the surface of the cutting part 112 to complete the cut. This helps reduce the impact of the plant on the connecting blocks 11 and further improves the stability of the cutting part 112 during operation.
[0035] Reference Figure 1 The cutting portions 112 of any two adjacent connecting blocks 11 point in opposite directions and are respectively directed to both sides of the cutting strip 1 along its length. When the cutting portion 112 cuts the plant, the plant slides on the surface of the cutting portion 112 and moves toward the opening 111. The fact that the cutting portions 112 of any two adjacent connecting blocks 11 point in opposite directions helps to reduce the probability that the plant is located in the opening 111, so that the plant slides back and forth between the cutting portions 112 of the two adjacent connecting blocks 11, thereby completing the plant cutting operation and improving the stability of the cutting.
[0036] Reference Figure 1The openings 111 on two adjacent connecting blocks 11 are alternately arranged in sequence. The openings 111 and the cutting parts 112 on two adjacent connecting blocks 11 are directly opposite each other. Since the plant part is relatively long, when part of the plant is located in the opening 111, the plant will rotate with the connecting block 11 during rotation and wrap around the connecting block 11. When the cutting strip 1 rotates, the plant will contact the adjacent cutting part 112, thereby realizing the cutting operation of the plant, which helps to reduce the probability of the plant wrapping around the surface of the connecting block 11.
[0037] Reference Figure 1 and Figure 2 A cutting element 2 is provided inside the opening 111 to cut the plant inside the opening 111. The cutting element 2 includes a support block 21 and two cutting blades 22. The support block 21 is located inside the opening 111 and is arranged along the length direction of the cutting strip 1. The support block 21 is fixedly connected to the connecting block 11. The two cutting blades 22 are respectively fixedly connected to both sides of the support block 21 along the width direction and are arranged along the length direction of the support block 21. When the plant is inside the opening 111, the support block 21 supports the two cutting blades 22, and the cutting blades 22 cut the plant inside the opening 111, so that the plant can be cut in time, which helps to reduce the probability of the plant getting tangled in the cutting strip 1.
[0038] Reference Figure 1 and Figure 3 Multiple support plates 3 are fixed to the outer side of the cutting strip 1. Each support plate 3 corresponds to a connecting block 11. The support plate 3 is located between two adjacent connecting blocks 11 and is arranged along the length of the cutting strip 1. Cutting plates 31 are fixed to both sides of the upper end of the support plate 3 near the connecting block 11, and the support plate 3 supports the cutting plates 31. The side of the cutting plate 3 away from the support plate 3 is located between the support plate 3 and the connecting block 11 and is located on the side of the support plate 3 away from the cutting strip 1. When the plant is located between two connecting blocks 11, the cutting part 112 cannot cut the plant. When the cutting part 112 contacts the plant, the overall strength of the plant is longer and the toughness of the plant is increased, which increases the difficulty of cutting. When the plant is located between two connecting blocks 11, the cutting plate 31 cuts the plant, thereby reducing the length of the plant.
[0039] Reference Figure 3 A baffle 32 is fixedly provided on the side of the lower end of the cutting plate 31 away from the support plate 3. The baffle 32 is arranged along the length of the cutting plate 31. The lower end of the baffle 32 is fixedly connected to the side of the connecting block 11 near the cutting strip 1. The baffle 32 seals the gap between the connecting block 11 and the support plate 3, which helps to reduce the probability of plants being located between the support plate 3 and the connecting block 11 and improves the convenience of cleaning plants on the cutting strip 1.
[0040] The implementation principle of a sharp and durable plant cutting wire according to an embodiment of this application is as follows: When a plant needs to be cut, the two ends of the cutting strip 1 along its length are connected to the cutting machine. The cutting strip 1 drives multiple connecting blocks 11 to rotate. During cutting, the pointed end of the cutting part 112 contacts the plant and cuts it. When the plant is located inside the opening 111, the cutting blade 22 inside the opening 111 cuts the plant. The cutting part 112 is asymmetrically arranged so that it contacts the plant at an angle and the plant slides on the surface of the cutting part 112 to complete the cutting. When the plant is located between two connecting blocks 11, the cutting part 112 cannot cut the plant. When the cutting part 112 contacts the plant, the overall strength of the plant is longer and the toughness of the plant is increased, which increases the difficulty of cutting. When the plant is located between two connecting blocks 11, the cutting plate 31 cuts the plant, thereby reducing the length of the plant and improving the efficiency of plant cutting.
[0041] Example 2 Reference Figure 4 The difference between this embodiment and embodiment 1 is that there are four connecting blocks 11, among which the cutting parts 112 of two opposite connecting blocks 11 point in opposite directions and respectively point to both sides of the cutting strip 1 along the length direction. The cutting parts 112 are asymmetrically designed on both sides along the length direction of the cutting strip 1. The asymmetrical design of the cutting parts 112 allows the cutting parts 112 to contact the plant in an inclined manner, and allows the plant to slide on the surface of the cutting parts 112 and complete the cutting. At this time, the plant is located in the opening 111. The cutting portions 112 of the other two connecting blocks 11 are symmetrically designed on both sides along the length of the cutting strip 1. The openings 111 of the two adjacent connecting blocks 11 are directly opposite the cutting portions 112. At this time, the plant is located in the opening 111. When the plant comes into contact with the adjacent connecting block 11, the cutting portions 112 cut and guide the plant, causing it to slide to both sides along the length of the cutting strip 1. The cutting strip 1 continues to rotate. When the plant comes into contact with the next connecting block 11, it still comes into contact with the side of the cutting portion 112 away from the cutting strip 1, so that the cutting portion 112 continues to come into contact with the plant in an inclined manner and completes the cutting. The two cutting portions 112 point in opposite directions, causing the plant to move and cut repeatedly within a certain area, which improves the cutting efficiency.
[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
