The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model embodiment provides a retractable membrane breaking device, such as Figure 1-4 As shown, the retractable film breaking device includes: a mounting frame 1, on which a knife disc 2 is rotatably mounted, and the knife disc 2 is used to break the plastic film; a detachable mounting shell 3 arranged on the mounting frame 1; a toothed plate 4 slidably mounted in the mounting shell 3 and retractably adjustable; a handle 5 mounted on the toothed plate 4 for grasping; and a positioning mechanism arranged on the mounting shell 3 for positioning the toothed plate 4.

[0022] It should be noted that, however, as the growth cycle of crops progresses, at certain stages, such as sowing, weeding, fertilizing or harvesting, farmers need to frequently break (cut) the plastic film covering the crops in order to carry out field operations. Currently, this operation process mainly relies on manual operation, that is, farmers need to squat on the ground and use scissors, knives or other manual tools to cut the plastic film section by section. This method is not only inefficient, but also consumes a lot of manpower and time. In addition, long-term squatting operation also has a significant impact on the health of farmers. Based on the above, a retractable film breaking device is needed to solve the above problems;

[0023] In this embodiment, the mounting frame 1 serves as the basic supporting structure of the entire device, and the blade disc 2 is a key component for performing film breaking operations. It is installed on the mounting frame 1 by rotation and can efficiently cut plastic film. The sharpness and durability of the blade disc 2 are specially designed to ensure that a good cutting effect can be maintained under long-term use. In addition, the rotation of the blade disc 2 may adopt various methods such as electric power, hydraulic pressure or mechanical transmission to adapt to different working conditions. The mounting shell 3 not only provides protection for internal components such as the tooth plate 4, but also through its detachable design, the sliding installation and telescopic adjustment function of the tooth plate 4 are a highlight of the device. Personnel can adjust the appropriate height to hold and use it according to their own height. The handle 5 installed on the tooth plate 4 provides a convenient control method for the operator. By holding the handle 5 and walking forward, the blade disc 2 is used to perform film breaking operations. The positioning mechanism is set on the mounting shell 3. The positioning mechanism is used to position the tooth plate 4 to ensure that it will not slide or loosen at will during the working process.

[0024] In a further preferred embodiment of the utility model, the positioning mechanism includes: a mounting hole 6 opened on the mounting shell 3; a toothed block 7 arranged in the mounting hole 6 and capable of being pulled out, the toothed block 7 being used to limit the toothed plate 4; an assembly frame 8, the assembly frame 8 being fixed on the mounting shell 3; a slide rod 9, the slide rod 9 being slidably mounted on the assembly frame 8, one end of the slide rod 9 being fixedly connected to the toothed block 7; and a spring 10 sleeved on the slide rod 9.

[0025] In this embodiment, the mounting hole 6 is a key structure provided on the mounting shell 3, which provides a space for the tooth slot block 7 to be installed and slided. This design enables the tooth slot block 7 to be flexibly pulled out when needed to realize the limiting function of the tooth slot plate 4; the tooth slot block 7 is arranged in the mounting hole 6 and can be pulled out to adjust its position. When the tooth slot block 7 is engaged with the tooth slot plate 4, it can effectively limit the tooth slot plate 4 to prevent it from sliding or moving unnecessarily during the working process. This limiting function ensures the accuracy and stability of the cutting operation. The assembly frame 8 is fixed on the mounting shell 3, providing a stable installation foundation for the slide bar 9. The slide bar 9 is slidably mounted on the assembly frame 8, and one end of the slide bar 9 is fixedly connected to the tooth slot block 7. This design allows the operator to conveniently adjust the position of the tooth slot block 7 by sliding the slide bar 9, thereby realizing the limiting or release of the tooth slot plate 4. The spring 10 is sleeved on the slide bar 9, and its function is to keep the tooth slot block 7 in a default limiting position when there is no external force. When the position of the tooth groove block 7 needs to be adjusted, the operator needs to overcome the elastic force of the spring 10 to slide the slide bar 9; and when the slide bar 9 is released, the elastic force of the spring 10 will automatically reset the tooth groove block 7 to the default position. This design not only improves the convenience of operation, but also ensures the stability and reliability of the positioning mechanism under long-term use.

[0026] In a further preferred embodiment of the utility model, a mounting block 11 is fixed on the top of the assembly frame 8 , a threaded column 12 is threadedly assembled on the mounting block 11 , and the top end of the threaded column 12 is fixedly connected to the bottom of the mounting shell 3 .

[0027] In this embodiment, the mounting block 11 is fixed on the top of the assembly frame 8, and the threaded column 12 is threadedly assembled on the mounting block 11, and its top end is fixedly connected to the bottom of the mounting shell 3, so as to facilitate the separation of the mounting shell 3 from the mounting frame 1.

[0028] In a further preferred embodiment of the utility model, a detachable protective shell 13 is provided outside the cutter disc 2, a shell cover 14 is installed on the assembly frame 8, and magnet blocks 15 are provided on the bottom of the shell cover 14 and the protective shell 13, and the corresponding magnet blocks 15 can be adsorbed on each other.

[0029] In this embodiment, a detachable protective shell 13 is provided outside the cutter disc 2. This design is mainly based on two considerations. First, the protective shell 13 can provide protection when the cutter disc 2 is not working, prevent it from being eroded by the external environment, and prevent people from being injured by accidental touch, which is beneficial to safety. Secondly, the detachable design allows the protective shell 13 to be easily removed when needed. A shell cover 14 is installed on the assembly frame 8, and magnet blocks 15 are provided on the bottom of the shell cover 14 and the protective shell 13. The corresponding magnet blocks 15 can be adsorbed on each other, which is convenient for limiting the protective shell 13 and also convenient for disassembly and separation.

[0030] In a further preferred embodiment of the present invention, a gripping sleeve 16 is disposed on the handle 5 . The gripping sleeve 16 is made of rubber and has a plurality of grooves.

[0031] In this embodiment, a gripping sleeve 16 made of rubber material is provided on the handle 5. This design greatly improves the user experience of the operator. The rubber material has good softness and elasticity, and can fit the contour of the operator's hand closely, providing a comfortable grip. At the same time, the anti-slip performance of the rubber material is also better than that of general materials, which helps to reduce the risk of slipping when operating in a wet or oily environment. Several grooves are provided on the gripping sleeve 16. The design of these grooves is not random, but based on ergonomic principles. The presence of the grooves increases the texture complexity of the surface of the gripping sleeve 16, further improving the anti-slip performance.

[0032] In a further preferred embodiment of the present invention, a sliding hole is provided on the assembly frame 8 , and the sliding hole is adapted to the sliding rod 9 , and a pull ring is fixedly installed on the other end of the sliding rod 9 .

[0033] In this embodiment, a sliding hole is provided on the assembly frame 8, and the sliding hole is adapted to the sliding rod 9. This design enables the sliding rod 9 to slide smoothly in the sliding hole, thereby realizing accurate control of the tooth groove block 7. The existence of the sliding hole not only provides a stable sliding track for the sliding rod 9, but also limits its sliding direction, preventing the sliding rod 9 from deflecting or shaking during the sliding process, thereby ensuring the stability and reliability of the positioning mechanism. A pull ring is fixedly installed on the other end of the sliding rod 9. The design of the pull ring enables the operator to pull the sliding rod 9 more conveniently.

[0034] In a further preferred embodiment of the utility model, a sliding opening is opened on the top of the mounting shell 3, and the sliding opening is adapted to the toothed plate 4. A threaded groove is arranged on the top of the toothed plate 4, and a threaded block is arranged in the threaded groove. The top end of the threaded block is fixedly connected to the handle 5.

[0035] In this embodiment, a sliding opening is provided on the top of the mounting shell 3, and the sliding opening is adapted to the toothed plate 4. This design enables the toothed plate 4 to slide smoothly along the track of the sliding opening, thereby achieving stability and smoothness of the telescopic membrane breaking device during the telescopic process. The existence of the sliding opening not only provides a clear sliding path for the toothed plate 4, but also limits its sliding direction, preventing the toothed plate 4 from deflecting or shaking during the sliding process, thereby ensuring the stability and reliability of the device.

[0036] In summary, the cutter disc 2 is used as a key component, and the specially designed sharpness and durability ensure the ability to efficiently cut plastic film for a long time, thereby improving work efficiency; the sliding installation and telescopic adjustment design of the toothed plate 4 enable the device to adapt to the needs of operators of different heights, and by adjusting to a suitable height, the comfort and convenience of use are improved; the positioning mechanism achieves precise positioning and stable limiting of the toothed plate 4 through the cooperation of the mounting hole 6, the toothed block 7, the slide rod 9 and the spring 10, prevents sliding or loosening during work, and ensures the accuracy and stability of the cutting operation; the detachable protective shell 13 design outside the cutter disc 2 protects the cutter disc 2 from erosion by the external environment, and also prevents people from being injured by accidental touch.
