Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a film-removing device and a film-removing method. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Mulching is a widely used planting method, but in the later stages of plant growth, such as tobacco, soil temperature is often too high while humidity is insufficient. If the mulch is not removed in time, the soil can become compacted and poorly aerated, damaging the roots and affecting the plant's later growth. Therefore, the mulch covering the field ridges should be removed promptly to improve soil permeability and ensure normal plant growth.

[0004] Traditional film removal methods are semi-automatic, requiring manual operation, which leads to high labor intensity and low efficiency, significantly increasing the cost of film removal. Currently, film removal machinery cannot simultaneously cut the film and separate the soil from both sides of the film, making it unsuitable for precision operations. Therefore, it is necessary to design film removal devices that meet operational requirements. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a film-removing device and method. By changing the method of removing the entire film, a double-sided film-removing method is adopted. First, the film-lifting mechanism separates the single-row mulch film into two parts, and then the film-rolling mechanism collects the mulch film from both sides, reducing tobacco leaf loss and effectively improving the film-removing effect.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0007] In a first aspect, the present invention provides a film peeling device, comprising a main body, a transmission mechanism, a film lifting mechanism, a film winding mechanism, a walking mechanism, and an operating mechanism;

[0008] A walking mechanism and a transmission mechanism are arranged below the main body; an operating mechanism is arranged above the main body; a film-raising mechanism and a film-winding mechanism are arranged at the front end of the main body, and the film-winding mechanism includes a fixing plate, which is fixedly installed at the front end of the main body and fixedly connected to the main body. The fixing plate consists of two vertical beams and one horizontal beam; the film-raising mechanism and the film-winding mechanism are arranged vertically, and the film-raising mechanism is set at the lower part of the film-winding mechanism through the fixing plate.

[0009] The film-lifting mechanism includes a film-cutting blade, a film-lifting shovel, a limiting plate, an adjusting plate, and a connecting roller; one end of the adjusting plate is connected to the fixed plate; there are two adjusting plates, each connected to a vertical beam of the fixed plate; the other end of the adjusting plate is provided with a film-lifting shovel, and one of the adjusting plates is also provided with a film-cutting blade near the film-lifting shovel, the film-cutting blade being connected to the adjusting plate via a connecting roller; each vertical beam of the fixed plate is provided with a limiting plate at its lower end, and the limiting plate and the adjusting plate constitute a soil penetration depth adjustment mechanism.

[0010] Furthermore, the film-lifting shovel is an arc-shaped film-lifting shovel, which is used to separate the film from the soil.

[0011] Furthermore, the cutting blade is a diagonal-striped cutting blade, which is used to cut the plastic film from the middle of the ridge.

[0012] Furthermore, the adjusting plate and the fixed plate are connected by fasteners, and the adjusting plate can rotate relative to the fixed plate.

[0013] Furthermore, the limiting plate is provided with limiting holes for controlling the rotation angle of the adjusting plate.

[0014] Furthermore, the film winding mechanism also includes a film feeding roller, a first height adjusting plate, a fixed shaft, a film winding roller, and a second height adjusting plate; there are two first height adjusting plates, which are respectively connected to the two vertical beams of the fixed plate. The film feeding roller is horizontally arranged on the first height adjusting plate, and the axial direction of the film feeding roller is perpendicular to the traveling direction of the device; the second height adjusting plate is arranged on the crossbeam of the fixed plate, and the crossbeam of the fixed plate is fastened to the second height adjusting plate. The second height adjusting plate is connected to one side of the fixed shaft, and the film winding roller is installed on the fixed shaft.

[0015] Furthermore, both the first height adjustment plate and the second height adjustment plate are connected to the fixed plate by fasteners, and both the first height adjustment plate and the second height adjustment plate are able to rotate relative to the fixed plate.

[0016] Furthermore, the limiting plate is provided with limiting holes for controlling the rotation angle of the adjusting plate.

[0017] Furthermore, the film-winding roller is a tapered cylinder with a gradually changing diameter, which facilitates the removal of the mulch film after the film-winding operation is completed.

[0018] Secondly, the present invention also provides a method for removing the film using a film-removing device, comprising:

[0019] When the film-unwrapping device reaches the work site, it uses a double-sided film-unwrapping method. The film-lifting mechanism is lowered by the operating mechanism, and the traveling mechanism moves between the rows. The film-lifting mechanism's cutting blade first separates the film of a single row into two parts, and the film-lifting shovel separates the film on the top of the row from the soil. Then, with manual assistance, one end of the film is fixed to the film-rolling roller. During the movement of the traveling mechanism, the cutting blade continues to separate the film of a single row into two parts, and the film-lifting shovel continues to separate the film on the top of the row from the soil. The film is then transported to the film-rolling roller by the film-feeding roller. After the film collection is completed, the film-rolling roller is removed from the fixed shaft. This process is repeated for the collection of film from different rows.

[0020] The beneficial effects of the present invention are as follows:

[0021] This invention's film-removing device employs a double-sided film-removing method. The film-lifting mechanism first divides the single-row mulch film into two parts, and then the film-rolling mechanism collects the film from both sides, reducing plant leaf loss and effectively improving the film-removing effect.

The film winding mechanism of this invention is equipped with a height adjustment plate, which allows for adjustment of the ground clearance of the film feeding roller and the film winding roller separately according to operational needs, thereby expanding the suitable range for film winding operations.

[0029] This invention discloses a film-removing device, comprising a main body 1, a transmission mechanism 2, a film-lifting mechanism 3, a film-rolling mechanism 4, a walking mechanism 5, and a control mechanism 6. The walking mechanism 5 and the transmission mechanism 2 are arranged below the main body 1; the control mechanism 6 is arranged above the main body 1; the film-lifting mechanism 3 and the film-rolling mechanism 4 are arranged at the front end of the main body 1; the film-lifting mechanism 3 and the film-rolling mechanism 4 are arranged vertically, with the film-lifting mechanism 3 located below the film-rolling mechanism 4. When the film-removing device is working, the walking mechanism 5 walks across the ridge in a single row, the film-lifting mechanism 3 first divides the film of a single ridge into two parts, and then the film-rolling mechanism 4 collects the film from both sides, reducing the loss of plant leaves and effectively improving the film-removing effect.

[0030] The film winding mechanism 4 includes a fixed plate 401, a film feeding roller 402, a first height adjusting plate 403, a fixed shaft 404, a film winding roller 405, and a second height adjusting plate 406. The fixed plate 401 is fixedly connected to the main body 1 and consists of two vertical beams and one horizontal beam. There are two first height adjusting plates 403, which are connected to the two vertical beams by fasteners. The film feeding roller 402 is horizontally arranged on the first height adjusting plate 403, and the axial direction of the film feeding roller 402 is perpendicular to the direction of travel of the device. The film feeding roller 402 and the first height adjusting plate 403 are detachably connected. The first height adjusting plate 403 can rotate relative to the fixed plate 401, thereby adjusting the height of the film feeding roller 402 to ensure the auxiliary conveying effect of the mulch film. A second height adjustment plate 406 is provided on the crossbeam of the fixed plate 401. The crossbeam of the fixed plate 401 is fastened to the second height adjustment plate 406 by fasteners. The second height adjustment plate 406 is connected to one side of the fixed shaft 404, and a film-winding roller 405 is installed on the fixed shaft 404. The second height adjustment plate 406 can rotate relative to the fixed plate 401, thereby adjusting the height of the film-winding roller 405. The film-winding roller 405 is a tapered cylinder with a gradually changing diameter, which facilitates the removal of the mulch film after the film-winding operation is completed. The first height adjustment plate 403 and the second height adjustment plate 406 of the film-winding mechanism 4 can adjust the ground clearance of the film-feeding roller 402 and the film-winding roller 405 respectively according to the operation requirements, thereby improving the suitable range of film-winding operations for plots with tobacco seedlings of different heights. The film-winding mechanism 4 adopts a combination of the film-feeding roller 402 and the film-winding roller 405 to improve the quality of film-winding operations.

[0031] The film-lifting mechanism 3 includes a cutting blade 301, a film-lifting shovel 302, a limiting plate 303, an adjusting plate 304, and a connecting roller 305. One end of the adjusting plate 304 is connected to the fixed plate 401 by fasteners, and the adjusting plate 304 can rotate relative to the fixed plate 401. There are two adjusting plates 304, each connected to the vertical beam of the fixed plate 401. The other end of the adjusting plate 304 is provided with a film-lifting shovel 302, which is an arc-shaped film-lifting shovel used to separate the mulch film from the soil. One of the adjusting plates 304 is also provided with a cutting blade 301 near the film-lifting shovel 302, which is diagonally woven. The cutting blade 301 is connected to the adjusting plate 304 via the connecting roller 305. Each vertical beam of the fixed plate 401 is provided with a limiting plate 303 at its lower end. The limiting plate 303 and the adjusting plate 304 constitute a soil penetration depth adjustment mechanism. The limiting plate 303 is provided with a limiting hole to control the rotation angle of the adjusting plate 304, and further control the soil penetration depth of the film lifting shovel 302. The height of the cutting blade 301 and the depth of the film lifting shovel 302 can be adjusted according to the ridge height to improve the film lifting effect and reduce power consumption.

[0032] The film-removing device adopts a double-sided film-removing method. When the film-removing device moves between the rows, the film-lifting mechanism 3 cuts the film blade 301 to separate the film of a single row into two parts. The film-lifting shovel 302 separates the film on the top of the row from the soil. Then, the film-feeding roller 402 of the film-rolling mechanism 4 assists in transporting the film. Finally, the film-rolling roller 405 collects the film from both sides, reducing tobacco leaf loss and effectively improving the film-removing effect.

[0033] The walking mechanism 5 is located below the main body 1. The walking mechanism 5 travels by track and can be used for plots with different humidity levels. The transmission mechanism 2 is connected to the walking mechanism 5, the film winding mechanism 4 and the film lifting mechanism 3 through a power transmission component, and transmits power to the walking mechanism 5, the film winding mechanism 4 and the film lifting mechanism 3. The upper part of the main body 1 is provided with an operating mechanism 6, which is connected to the hydraulic system and is used to control the speed of walking and the speed of the film winding roller 405.

[0034] A film-removing device includes the following steps for removing a film:

[0035] When the film-unwrapping device reaches the work site, the film-lifting mechanism 3 is lowered by the operating mechanism 6, and the traveling mechanism 5 moves between the rows. The film-lifting mechanism 3's cutting blade 301 separates the film of a single row into two parts, and the film-lifting shovel 302 separates the film on the top of the row from the soil. Then, with manual assistance, one end of the film is fixed to the film-rolling roller 405. During the movement of the traveling mechanism 5, the cutting blade 301 continues to separate the film of a single row into two parts, and the film-lifting shovel 302 continues to separate the film on the top of the row from the soil. The film is then transported to the film-rolling roller 405 by the film-feeding roller 402. After the film collection is completed, the film-rolling roller 405 is removed from the fixed shaft 404. Since the film-rolling roller 405 is a conical cylinder, it is convenient to remove the film after the film-rolling operation is completed. The film can be directly removed from the end with the smaller diameter. For the recycling of film in different rows, this process can be repeated to realize the film-unwrapping, film-rolling, and other film recycling processes.

[0036] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
