Description

Technical Field

[0001] This utility model relates to the technical field of agricultural film laying and cutting devices, and in particular to an intelligent agricultural film laying and cutting device for planting Chinese medicinal herbs under forest. Background Technology

[0002] Understory cultivation of medicinal herbs is widely used due to its advantages such as moisture retention, shade, and excellent ecological conditions. Laying agricultural film has become an important step in understory cultivation to improve soil temperature and humidity, suppress weeds, and increase the germination rate of medicinal herbs. However, the complex terrain and uneven ground under forest cover make traditional manual film laying labor-intensive, inefficient, and the quality of the film is easily affected by human operation, often resulting in problems such as loose film, wrinkles, or poor adhesion.

[0003] Existing agricultural film laying equipment is mainly designed for open farmland, and is large in size and lacks mobility, making it difficult to use in narrow spaces and with limited paths under forest cover. At the same time, these devices generally still require manual intervention in steps such as guiding the film head, compacting the film edges, and cutting the film at the field, making it impossible to achieve full automation. This results in poor operational continuity, high personnel input, and affects the efficiency of medicinal herb cultivation.

[0004] Furthermore, existing technologies still suffer from insufficient structural adaptability in areas such as membrane flattening, tension control, and soil covering and edge pressing, resulting in uneven membrane laying effects under different terrains. In particular, membrane tail cutting still relies on manual operation, which affects the work rhythm and is not conducive to maintaining consistent membrane quality. Utility Model Content

[0005] In view of this, it is necessary to provide an intelligent agricultural film laying device for the cultivation of Chinese medicinal herbs under forest cover, so as to at least solve the above problems.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This application provides an intelligent agricultural film laying and cutting device for planting medicinal herbs under forest cover, which is installed on a frame. The frame is sequentially equipped with a trencher, film-attaching roller, film-spreading roller, film-pressing roller, edge-pressing wheel, and soil-covering disc along the forward direction of the device; wherein... Film-mounting rollers are used to place and transport agricultural film; The film spreading roller consists of two rollers that rotate relative to each other, and is used to pull out and flatten the agricultural film; The film pressing roller is positioned after the film spreading roller and is used to press the agricultural film onto the ground surface; The edge pressing rollers are located on both sides of the film pressing roller and are used to press the edge of the agricultural film into the groove formed by the furrow opener; The soil-covering disc is used to cover the soil above the edge of the agricultural film and fix it in place; The frame is also equipped with an initial laying mechanism, which includes a clamping member that can hold the agricultural film and a film guiding assembly that can drive the clamping member to move, for guiding the agricultural film to the underside of the pressing roller when the film laying begins. The frame is further provided with an agricultural film cutting mechanism, which includes a cutter disposed above the agricultural film and a drive assembly for driving the cutter to move up and down reciprocatingly, so that the cutter cuts the agricultural film at a designated position.

[0007] In a further embodiment, the two rollers of the spreading roller are connected by gear meshing or a synchronous transmission structure.

[0008] In a further embodiment, a film-through gap is formed between the two rollers of the spreading roller for discharging the film, and the axes of the two rollers are arranged parallel to each other.

[0009] In a further embodiment, the pressure wheel has an arc-shaped or parabolic outer contour, and its cross-sectional curve gradually dips down along the pressure direction.

[0010] In a further embodiment, the maximum depression of the outer contour of the pressure wheel towards the ground is 5–15 mm.

[0011] In a further embodiment, the soil-covering disc has an angle of 35° to 45° relative to the direction of travel of the device, and an angle of inclination of 15° to 25° relative to the vertical direction.

[0012] In a further embodiment, the film-guiding assembly includes a film-guiding rod rotatable about a fixed axis, the film-guiding rod being driven by a motor to oscillate or rotate in a vertical plane.

[0013] In a further embodiment, the clamping member is disposed at the end of the film-guiding rod and includes a pair of openable clamping blocks or elastic clamping structures for temporarily clamping the agricultural film head.

[0014] In a further embodiment, the drive assembly includes an eccentric cam, a slider cooperating with the cam, and an elastic element for resetting the cutter.

[0015] In a further embodiment, the eccentric cam is driven to rotate by a motor, and the cutting blade reciprocates linearly along the slide rail or guide structure.

[0016] Compared with the prior art, the present invention has the following advantages: The automated control system enables automatic laying, compaction, soil covering, and cutting of agricultural film, reducing manual intervention and improving operational efficiency and consistency in film laying. Compared to traditional manual film laying methods, it reduces labor intensity and manpower consumption, and solves the problem of traditional equipment being unable to adapt to complex terrain under forest cover. Secondly, the film cutting function of this device is designed to eliminate the need for manual cutting at the field edge, avoiding the problem of relying on manual cutting of the film tail after laying, thus improving the continuity and automation level of the operation. In addition, the design of key components such as the edge pressing wheel and soil covering disc ensures accurate compaction and stable fixation of the film edge, improves the soil covering effect, effectively prevents the film edge from being blown away by the wind, and enhances the stability and protective performance of the agricultural film.

[0019] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0020] This application relates to an intelligent film-laying and cutting device for planting medicinal herbs under forest cover. Its core objective is to improve the automation level of film laying, reduce manual intervention, and enhance operational efficiency and consistency in film laying quality. It is particularly suitable for complex terrain and small-scale planting environments under forest cover. Film laying typically relies on manual operation, which is labor-intensive and inefficient. Furthermore, traditional equipment still requires manual cutting of the film tail after laying, resulting in low operational efficiency. Especially in forest environments, traditional machinery has poor adaptability and cannot effectively complete automatic film laying and cutting. To overcome this problem, this application provides an intelligent device capable of automatically laying agricultural film, intelligently cutting the film tail, and adapting to forest planting environments.

[0021] like Figure 1 and Figure 2 As shown, the frame 1 of this device is mounted on a tractor or similar traction equipment. Along the device's forward direction, several functional components are sequentially installed, including a trench opener 2, a film-attaching roller 3, a film-spreading roller 4, a film-pressing roller 5, an edge-pressing wheel 6, and a soil-covering disc 7. These components work together to automate the process from film laying to soil covering. The trench opener 2 is used to create trenches on the ground suitable for pressing the agricultural film, and the film-attaching roller 3 is responsible for placing and conveying the agricultural film. The film-attaching roller 3 is a hollow roller with a diameter of approximately 250mm and a length of 1.5m, made of aluminum alloy, and is lightweight and wear-resistant. During the film laying process, the two rollers 41 of the film-spreading roller 4 are connected to each other through a gear drive or synchronous drive structure to ensure that the agricultural film can be smoothly spread and laid at a consistent length with the ground, thereby ensuring the quality of film laying. The two rollers 41 of the film-spreading roller 4 have a diameter of 280mm, and the gap between the rollers 41 is 10mm to ensure that the agricultural film can pass smoothly and achieve a good spreading effect. The axes of the film spreading rollers 4 are arranged in parallel, and the roller bodies 41 are connected by gear meshing or synchronous belt drive to achieve uniform and synchronous rotation.

[0022] like Figure 5As shown, the film-pressing roller 5 is positioned after the film-spreading roller 4 to firmly press the agricultural film onto the ground surface. The film-pressing roller 5 has a diameter of 300mm and a length of 1.6m, and is made of high-strength rubber material to ensure good compaction of the agricultural film and prevent it from lifting due to external factors (such as wind). The edge-pressing roller 6 and the soil-covering disc 7 are key components in this device to ensure the tightness and stability of the film edges. The edge-pressing roller 6 has an arc-shaped or parabolic outer contour, and its cross-sectional curve gradually dips along the pressing direction, effectively pressing the edge of the agricultural film into the groove formed by the furrow opener 2, thereby preventing the film edge from falling off or lifting during subsequent operations. The maximum downward dip of the outer contour of the edge-pressing roller 6 towards the ground is 10mm, ensuring the stability of the pressed film edge. The soil-covering disc 7 has a diameter of 240mm and a thickness of 6mm, with a 40° deflection angle relative to the forward direction of the device and a 20° tilt angle relative to the vertical direction. This design ensures effective soil covering of agricultural film under different soil conditions, avoiding the phenomenon of film edges curling up or uneven soil covering.

[0023] like Figure 2 As shown, to achieve the initial stage of automatic film laying, this device also includes an initial laying mechanism 8, comprising a film guiding assembly 82 and a clamping component 81. The film guiding assembly 82 consists of a motor-driven film guiding rod, which automatically guides the agricultural film to below the pressure roller 5 at the start of film laying. The clamping component 81 is used to fix the film head, ensuring stability during the laying process. The film guiding rod is 1.2m long, and the motor drives it at a speed of 30r / min, ensuring that the agricultural film smoothly enters the pressure roller 5, avoiding the cumbersome operation of manually pulling the film head required in traditional devices. The film guiding assembly 82, driven by a motor, ensures that the agricultural film can be laid smoothly without manual operation, greatly improving work efficiency and quality.

[0024] like Figure 3 and Figure 4 As shown, after the agricultural film is laid to the edge of the field, the intelligent cutting function of this device begins to operate. The agricultural film cutting mechanism 9 includes a cutter 91 and a drive assembly 92. The cutter 91 is driven by a motor to move up and down reciprocatingly, automatically cutting the agricultural film at a predetermined position. The design of the cutting function ensures that the film tail can be accurately cut without manual intervention, thereby improving work efficiency and avoiding irregularities and inconsistencies that may occur during manual cutting. The cutter 91 uses a single-blade design with a blade length of 1.1m and a width of 3mm, exhibiting excellent wear resistance. The transmission of the cutter 91 is achieved through the cooperation of an eccentric cam 921 and a slider 922, ensuring the accuracy and stability of the cutting action. By designing a reset device for the eccentric cam 921 and the elastic element 923 (i.e., a spring), the cutter 91 can quickly reset after cutting, ensuring the efficient operation of the device.

[0025] The control system of this device adopts centralized PLC control, in conjunction with multiple motors and transmission devices, to ensure the coordinated operation of all components. The PLC control system can adjust the operating speed and working status of each motor according to work needs, thereby optimizing the overall process of film laying, cutting, and other operations. The control system can also monitor the working status of each component in real time, ensuring efficient cooperation between the functional modules of the device during operation.

[0026] This application provides a highly efficient, stable, and intelligent agricultural film laying and cutting device, which can significantly improve the operational efficiency of understory medicinal herb cultivation, reduce labor intensity, and ensure the quality and stability of agricultural film laying. Compared with existing technologies, this device has a higher level of automation and can complete the entire process from laying to cutting without relying on manual labor. It is particularly suitable for complex environments such as understory planting and has broad application prospects.

[0027] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
