Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a high-efficiency film-wrapping machine with anti-tear and anti-breakage properties, and a film collection method. Background Technology

[0002] Removing the plastic film covering tobacco seedlings is a crucial step in tobacco production. 30-35 days after transplanting, the film needs to be removed from the seedlings to improve soil permeability, increase the area of ​​the field receiving rainfall, and ensure the roots receive sufficient water. This also facilitates subsequent production processes. Currently, removing the film in tobacco fields mainly relies on manual labor, which is inefficient, time-consuming, labor-intensive, and requires significant physical exertion. Existing film-removing machines on the market use a one-piece film removal method, which can easily damage the tobacco plants during the process, making these machines unsuitable for widespread use.

[0003] Chinese invention patent application CN119174364A discloses a film-removing device and method, employing a double-sided film-removing approach. First, the film-removing mechanism uses a cutting blade to separate the single-row mulch film into two parts. A film-removing shovel then separates the top mulch film from the soil. A film-rolling mechanism collects the film from both sides, and a feeding roller assists in transporting the film onto the rolling roller. After collection, the rolling roller is removed from the fixed shaft. While this solution effectively collects the mulch film onto the rolling roller, it still presents the following technical limitations. Problems: 1. When the plastic film is tightly compacted by the soil, even though the film-lifting shovel loosens and separates the film from the soil, the soil adhering to the film is difficult to shake off and remove, resulting in increased resistance and easy film breakage during film winding; 2. As the film winding device winds the film, the diameter of the winding roller gradually increases, and the tension gradually increases. Correspondingly, the film winding resistance is objectively unstable, making the film prone to breakage; 3. After a certain amount of film is collected using the winding roller, because the film is wound in multiple layers, the film is wound very tightly on the winding roller, and the film on the winding roller cannot be quickly removed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an efficient integrated machine for twisting and preventing film breakage, as well as a film collection method. This machine can achieve functions such as twisting, passive soil removal, tension buffering adjustment, and uniform winding, and can efficiently and quickly collect the film, avoiding film breakage.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] In a first aspect, embodiments of the present invention provide a high-efficiency film twisting and anti-tear-breakage integrated film wrapping machine, including a walking chassis, a dividing device, a loosening shovel, a film twisting mechanism, a tension buffer adjustment mechanism, a guide support assembly, an automatic reciprocating mechanism, a wrapping mechanism, and a transmission system;

[0007] The loosening shovel, film-twisting mechanism, tension buffer adjustment mechanism, guide support assembly, automatic reciprocating mechanism, and winding mechanism are all symmetrically arranged with respect to the left and right center planes of the traveling chassis. The dividing device is located at the front center of the traveling chassis. The loosening shovel is located at the front end of the traveling chassis near the edge of the frame. The film-twisting mechanism is located in the front half of the traveling chassis, behind the loosening shovel, and maintains a set distance and offset from the dividing device. The tension buffer adjustment mechanism is located in the middle of the traveling chassis, behind the film-twisting mechanism. The guide support assemblies are distributed in the rear half of the traveling chassis, behind the tension buffer adjustment mechanism, with each guide support frame maintaining a set interval. The automatic reciprocating mechanism is located in front of the highest guide support frame and above the tension buffer adjustment mechanism. The winding mechanism is located in front of the automatic reciprocating mechanism and above the film-twisting mechanism. The transmission system realizes the rotation of the winding mechanism and the film-twisting mechanism, as well as the linear motion of the slider of the automatic reciprocating mechanism.

[0008] As a further implementation, the film-twisting mechanism includes a left film-twisting mechanism and a right film-twisting mechanism with identical structures, each including a film-twisting disc welded together, a support plate, and a first sprocket, wherein the film-twisting disc welded together is hinged to the support plate through a bearing, and the film-twisting disc welded together is connected to the first sprocket through a flat key.

[0009] As a further implementation, the film-twisting disc welding includes a disc, a rotating sleeve, a bent tube, and reinforcing plates, wherein the protruding tube of the disc is fitted into the rotating sleeve and welded together, the concave edge of the disc is welded together with the bent tube, and multiple reinforcing plates are evenly arranged and welded onto the disc, while multiple reinforcing plates are welded together with the ends of the rotating sleeve.

[0010] As a further implementation, the tension buffer adjustment mechanism includes a left tension buffer adjustment mechanism and a right tension buffer adjustment mechanism with identical structures, each including an adjustment bracket weld, a circular ring weld, a rotating shaft, and elastic bands. The circular ring weld is connected to the adjustment bracket weld via the rotating shaft, and the circular ring weld is fixed to the rotating shaft by a pin. The left and right circular ring welds are spaced apart by a set distance. The rotating shaft is hinged to the two vertical tubes of the adjustment bracket weld via bearings. Multiple elastic bands are fixedly connected to the outer rings of the two circular ring welds respectively, and are evenly distributed along the outer rings of the circular ring welds.

[0011] As a further implementation, the winding mechanism includes a support frame welded together, a wrapping frame assembly, a connecting shaft, a second sprocket, and a third sprocket. Two wrapping frame assemblies are mounted on the support frame welded together, arranged in parallel, and symmetrical about the left and right center planes of the support frame welded together. Each wrapping frame assembly is rotatably connected to the support frame welded together via a bearing. The connecting shaft is connected to the long shaft sleeves of the left and right wrapping frame assemblies respectively via flat keys. The second sprocket and the third sprocket are fixed on the connecting shaft, driving the rotating shaft to rotate.

[0012] As a further implementation, the film wrapping frame assembly includes annular frame welded together, film winding roller, winding shaft, long shaft sleeve, short shaft sleeve, and handle. The long shaft sleeve and short shaft sleeve are respectively hinged to the fourth rectangular tube through bearings. The handle is welded to the winding shaft. The winding shaft passes through the short shaft sleeve, the annular frame welded together on the left and right sides, and the long shaft sleeve in sequence. The short shaft sleeve, the annular frame welded together on the left and right sides, and the long shaft sleeve are respectively fixed to the winding shaft. The annular frame welded together on the left and right sides are fixedly connected by the film winding roller.

[0013] As a further implementation, the guide support assembly includes a left guide support assembly and a right guide support assembly with identical structures, each including a first guide support frame, a second guide support frame and a third guide support frame, wherein the first guide support frame, the second guide support frame and the third guide support frame are spaced apart by a set distance, and the third guide support frame is higher than the first guide support frame and the second guide support frame.

[0014] As a further implementation, the power source of the transmission system comes from the power system of the chassis.

[0015] As a further implementation, the automatic reciprocating mechanism includes a lead screw, a slider, and a guide shaft. The lead screw and the guide shaft are parallel to each other. One end of the slider is mounted on the lead screw, and the other end is mounted on the guide shaft. The lead screws of the two automatic reciprocating mechanisms are driven to rotate by a tenth sprocket, thereby realizing the linear motion of the slider. A traction hole is provided in the slider.

[0016] Secondly, embodiments of the present invention also provide a film-receiving method, employing the aforementioned high-efficiency film-twisting and tear-resistant integrated film-wrapping machine, comprising:

[0017] The chassis moves along the ridge, and the semi-circular blade of the dividing device cuts the mulch film on the tobacco ridge into two parts. The loosening shovels on both sides loosen and separate the mulch film from the soil. The divided mulch film enters the left and right film twisting mechanisms respectively. The left and right film twisting mechanisms rotate the mulch film from the middle position and rotate it outward from the top, twisting the mulch film from a flat unfolded state into a thin rope state.

[0018] After the plastic film comes out from the left and right film twisting mechanisms, it is guided to the first guide support frame of the guide support assembly, rotates around the tension buffer adjustment mechanism, and then passes through the second guide support frame and the third guide support frame in sequence. It then enters the slider traction hole of the automatic reciprocating mechanism and is fixed to the film winding roller of the winding mechanism. The slider pulls the plastic film to make a uniform reciprocating motion. With the uniform rotation of the winding mechanism, the plastic film is evenly wound onto the film winding frame assembly.

[0019] Compared with the prior art, the advantages and positive effects of this invention are:

[0020] 1. This invention uses a film-twisting mechanism to twist the mulch film into a thin rope shape, causing soil clods attached to the film to automatically detach, achieving the purpose of soil removal and reducing resistance during film collection. Simultaneously, twisting the film into a thin rope shape increases its toughness, effectively preventing breakage. Furthermore, due to the complexity of the working environment, the machine may experience speed instability during movement, leading to uneven tension during film collection. The tension buffer adjustment mechanism ensures balanced force on the mulch film, effectively preventing breakage or loosening. As the diameter of the mulch film wound onto the film-wrapping frame gradually increases, the tension on the film gradually increases; the tension buffer adjustment mechanism further enhances this effect. The mechanism effectively adjusts uneven tension during the film collection process, preventing film breakage. When the tension reaches its limit during film collection, it affects the function of the tension buffer adjustment mechanism. At this time, adjusting the machine's throttle appropriately and increasing the travel speed will ensure that the tension buffer adjustment mechanism functions normally. Simultaneously, the guide support component, automatic reciprocating mechanism, film twisting mechanism, and tension buffer adjustment mechanism work together to wind the mulch film onto the winding mechanism, finally achieving mulch film recycling. This film collection method effectively solves the problem of film breakage and also avoids damage to tobacco seedlings caused by collecting the entire mulch film. This film collection method is fast and efficient.

[0021] 2. This invention, through the design of a specific structure for the winding mechanism, allows for the removal of the roll of mulch film once the mechanism is full of film. This is achieved by removing the pins between the two side bushings, the film wrapping frame assembly, and the winding shaft. Then, the handle is pulled outwards to remove the winding shaft, the film wrapping frame assembly is removed, and the screws on one side are unscrewed. The assembly and disassembly actions are reversed. This structure makes assembling and disassembling mulch film convenient, quick, and efficient, saving a significant amount of time.

[0043] For ease of description, the words "up," "down," "left," and "right" appearing in this invention only indicate that they are consistent with the up, down, left, and right directions of the accompanying drawings themselves. They do not limit the structure and are merely for the purpose of facilitating the description of this invention and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0044] As described in the background section, when the plastic film is tightly compacted by the soil, although the film-lifting shovel loosens and separates the film from the soil, the soil adhering to the film is difficult to shake off and remove, resulting in increased resistance and easy film breakage during film winding. As the film winding device winds the film, the diameter of the winding roller gradually increases, and the tension gradually increases, resulting in objective instability in the winding resistance and easy film breakage. After a certain amount of film is collected using the winding roller, the film is wrapped very tightly on the winding roller due to the multi-layer winding, and the film on the winding roller cannot be quickly removed. To address the above problems, this invention proposes a high-efficiency film-twisting and anti-tear-breakage integrated film-winding machine and film winding method.

[0045] Example 1:

[0046] This embodiment provides a high-efficiency film twisting and anti-tear wrapping integrated machine, such as... Figure 1 , Figure 2 As shown, the system includes a remote-controlled walking chassis 1, a dividing device 2, a loosening shovel 3, a film-tightening mechanism 4, a tension buffer adjustment mechanism 5, a guide support assembly, an automatic reciprocating mechanism 7, a winding mechanism 8, and a transmission system 9. The loosening shovel 3, film-tightening mechanism 4, tension buffer adjustment mechanism 5, guide support assembly, automatic reciprocating mechanism 7, and winding mechanism 8 are all symmetrically arranged around the left and right center planes of the chassis. The dividing device 2 is located at the front end of the remote-controlled walking chassis 1, slightly to the left of its left and right center planes. The loosening shovel 3 is located at the front end of the remote-controlled walking chassis 1 near the edge of the frame. The film-tightening mechanism 4 is located in the front half of the remote-controlled walking chassis 1, behind the loosening shovel 3, and maintains a certain distance and offset from the dividing device 2. The tension buffer adjustment mechanism 5 is located in the middle of the remote-controlled walking chassis 1, behind the film-tightening mechanism 4. The guide support assembly is distributed in the rear half of the remote-controlled walking chassis 1, behind the tension buffer adjustment mechanism 5, with guide support frames 6-1, 6-2, and 6-3 maintaining a certain interval. The automatic reciprocating mechanism 7 is positioned in front of the guide support frame 6-3 and above the tension buffer adjustment mechanism 5. The winding mechanism 8 is positioned in front of the automatic reciprocating mechanism 7 and above the film twisting mechanism 4.

[0047] This invention uses a film-twisting mechanism to twist the mulch film into a thin rope shape, causing soil clods attached to the film to automatically detach, achieving the purpose of soil removal and reducing resistance during film collection. Simultaneously, twisting the film into a thin rope shape increases its toughness, effectively preventing breakage. Furthermore, due to the complexity of the working environment, the machine may experience speed instability during movement, leading to uneven tension during film collection. The tension buffer adjustment mechanism ensures balanced force on the mulch film, effectively preventing breakage or loosening. As the diameter of the mulch film wound onto the film-wrapping frame gradually increases, the tension on the film gradually increases; the tension buffer adjustment mechanism... The structure can effectively adjust uneven tension during the film collection process, preventing film breakage. When the tension reaches its limit during film collection, it will affect the function of the tension buffer adjustment mechanism. At this time, adjusting the machine's throttle appropriately and increasing the walking speed will ensure that the tension buffer adjustment mechanism functions normally. At the same time, the guide support component, automatic reciprocating mechanism, film twisting mechanism, and tension buffer adjustment mechanism work together to wind the mulch film onto the winding mechanism, finally realizing the recovery of the mulch film. This film collection method can effectively solve the problem of film breakage and also avoid damage to tobacco seedlings caused by the collection of the entire mulch film. This film collection method is fast and efficient.

The bent pipe 4-1-3 is mainly used to transfer the film. The cut film enters the bent pipes of the left and right film-twisting mechanisms, and then, along the disc surface, enters the protruding tube of the disc radially.

[0059] This embodiment provides a method for collecting film using a high-efficiency film-wrapping and anti-tear-break integrated film-wrapping machine. The equipment described in Embodiment 1 includes: a remote-controlled walking chassis that travels along the ridge; a semi-circular blade of a dividing device that cuts the film on the tobacco ridge into two parts, wherein the depth and angle of the semi-circular blade can be adjusted according to the working conditions; and loosening shovels on both sides that loosen and separate the film from the soil, wherein the depth of the loosening shovels can be adjusted according to the working conditions. The divided film enters the curved tubes of the left and right film-wrapping mechanisms, respectively, and, following the surface of the disc, radially enters the protruding tubes of the disc. The left and right film-wrapping mechanisms rotate the film outward from the cut position, twisting the film from a flat, unfolded state into a thin rope state.

[0060] The plastic film, wound into a thin rope shape, passes through the protruding tube of the disc, along the rotating shaft of the first guide support frame, winds around the tension buffer adjustment mechanism, and then sequentially passes through the rotating shafts of the second and third guide support frames. It then enters the traction hole of the slider 7-1 of the automatic reciprocating mechanism and is fixed to the film winding roller of the winding mechanism. The slider pulls the plastic film in a uniform reciprocating motion. As the winding mechanism rotates at a uniform speed, the plastic film is evenly wound onto the film winding frame assembly. The movement of the plastic film is as follows... Figure 8 As shown.

[0061] Furthermore, once the winding mechanism is full of mulch film, remove the pins from both side bushings (long bushing 8-2-4, short bushing 8-2-5) and the connection between the wrapping frame assembly and the winding shaft. Then, pull the handle outward to remove the winding shaft, remove the wrapping frame assembly, and unscrew one side to unload the roll of mulch film. Assembly and disassembly are the reverse of each other. This structure makes assembling and disassembling mulch film convenient, quick, and efficient, saving a significant amount of time.
