Description

Technical Field

[0001] This invention relates to the field of tobacco seedling planting technology, specifically a self-propelled tobacco ridge film removal machine and a method for collecting tobacco ridge film. Background Technology

[0002] The technology of mulching tobacco crops with plastic film is widely used. The plastic film has the advantages of saving water and resisting drought, increasing moisture and retaining soil moisture, and controlling weeds. When the time is right, the plastic film needs to be removed in time. If the plastic film is not removed in time, the tobacco seedlings are prone to high temperature scorching in the subsequent hot weather.

[0003] Chinese invention patent CN105660266B discloses a tobacco seedling film removal machine, which includes a frame and a film-winding roller. The machine continuously collects film from tobacco rows by moving the frame and rotating the film-winding roller synchronously. While this reduces manual labor intensity, it still has the following problems: 1. Because the film is covered with soil on the tobacco rows, directly collecting the film by rotating the film-winding roller sometimes makes it difficult to pull the film out of the soil. As the film-winding roller continues to pull the film forcefully, it may damage the tobacco seedlings. 2. After collecting a certain amount of film using the film-winding roller, the film is wrapped very tightly on the roller due to its multi-layered winding. Since the film-winding roller is fixed to the drive shaft, the collected film is not easily and quickly removed. Summary of the Invention

[0004] The purpose of this invention is to provide a self-propelled tobacco ridge film removal machine and a method for collecting tobacco ridge film. The film removal knife effectively separates the two sides of the film from the soil, which facilitates the subsequent winding and collection of the film. At the same time, after the two sides of the film are separated from the soil, the problem of pulling the film hard is effectively prevented, thereby greatly reducing the occurrence of damage to tobacco seedlings caused by film winding. Furthermore, by utilizing the function that one end of the cylindrical film winding frame can become conical, the film collected on the cylindrical film winding frame can be easily removed, thereby improving the film collection efficiency.

[0005] The technical solution adopted by this invention to solve its technical problem is: a self-propelled tobacco ridge film peeling machine, including an engine, a traveling reducer, a traveling mechanism, a film picking mechanism, and a film winding mechanism. The engine, traveling reducer, film picking mechanism, and film winding mechanism are all mounted on the traveling mechanism. The film picking mechanism includes a square film picking frame that can rotate freely. The film winding mechanism includes a cylindrical film winding frame that can rotate freely. The square film picking frame is adjacent to the film feeding side of the cylindrical film winding frame. The cylindrical film winding frame can be transformed into a conical structure. The engine can provide traveling power to the traveling mechanism and can provide rotational power to the square film picking frame and the cylindrical film winding frame.

The film-forming knife is distributed in an inclined state with the front lower and the back higher.

[0009] Furthermore, a first vertical fixing rod is provided in front of each of the first vertical sleeves. The upper part of the first vertical fixing rod is fixedly connected to the rear traveling bracket, and a swing limiting rod is hinged to the lower part of the first vertical fixing rod. The other end of the swing limiting rod is hinged to the outer wall of the corresponding first vertical sleeve.

[0010] Furthermore, the square film-picking frame is rotatably mounted on the rear traveling support along the left and right directions. A first drive gear is provided at the left end of the square film-picking frame, and a second drive gear that meshes with the first drive gear is provided on the rear traveling support. A first sprocket coaxial with the second drive gear is provided on one side of the second drive gear.

[0011] Furthermore, the cylindrical film winding frame includes a rotating support shaft. The left end of the rotating support shaft is fitted into a bearing seat of the rear traveling bracket. The right end of the rotating support shaft is rotated and supported by two bearings distributed front and rear. A worm gear reducer is fixedly installed on the right rear part of the rear traveling bracket. The power output end of the worm gear reducer is transmitted to the rotating support shaft via bevel gear transmission. A second sprocket is installed at the left end of the rotating support shaft. A large circular plate is fixedly installed at the left end of the rotating support shaft. A small circular plate is fitted at the right end of the rotating support shaft. The small circular plate can slide and be positioned freely on the rotating support shaft. Several sets of retractable rod assemblies are arranged between the large and small circular plates, evenly spaced along the circumference of the rotating support shaft. Each set of retractable rod assemblies includes a first support rod and a first folding rod. The left end of the first support rod is hinged to the right side wall of the large circular plate. The inner end of the first folding rod is hinged to the right side wall of the small circular plate. The right end of the first support rod is hinged to the left side wall of the outer end of the first folding rod.

[0012] Furthermore, the engine is a gasoline engine. A first pulley is provided at the power output end of the gasoline engine.

A transmission belt is fitted between the first pulley and the second pulley, between the third pulley and the fourth pulley, and between the fifth pulley and the sixth pulley. A transmission chain is fitted between the first sprocket and the second sprocket.

[0013] Furthermore, the two bearings are mounted on a cantilever rod, the front end of which is hinged to a support end of the rear travel bracket via a hinge.

A limiting block is fixed to the front end of the second swing rod, located above the first swing rod. The limiting block is located behind the hinged connection between the first and second swing rods. When the upper sidewall of the first swing rod presses against the lower part of the limiting block, the included angle between the first and second swing rods is between 140° and 170°.

[0014] A method for collecting tobacco ridge film includes a self-propelled tobacco ridge film-lifting machine as described above. The method further includes the following film collection steps: moving the entire film-lifting machine above one end of the tobacco ridge; adjusting the film-lifting blades on the left and right sides so that the film-lifting blades are located on both sides of the bottom of the tobacco ridge; pulling up one end of the film below the film-lifting machine, so that the free end of the film first passes over the top of the square film-lifting frame and then wraps around and fixes itself to the columnar film-wrapping frame from the bottom; as the film-lifting machine moves along the tobacco ridge, looking at the film-lifting machine from the left side, the columnar film-wrapping frame rotates counterclockwise and the square film-lifting frame rotates clockwise.

[0015] The beneficial effects of this invention are as follows: the arrangement of the various actuators is reasonable, facilitating the automatic collection of film on tobacco ridges; the walking mechanism enables automatic movement, facilitating continuous automatic collection of film on tobacco ridges, while reducing labor intensity and improving collection efficiency; during movement, the reciprocating motion of the lifting blade automatically separates the film from the soil on both sides, allowing for flexible lifting and effectively preventing damage to tobacco seedlings caused by hard pulling; the continuous rotation of the square film-lifting frame shakes the film up and down, which helps to remove any adhering film. The soil clods on top of the film are shaken off, preventing them from being trapped in the collected film roll. Simultaneously, as the square film-lifting frame pushes the film upwards, it facilitates tension between the frame and the cylindrical film winding frame, allowing the film to be tightly wound on the frame and enabling it to collect more film at once. When the small circular plate slides towards the large circular plate, the diameter on the right side of the cylindrical film winding frame decreases, transforming it from a cylindrical to a conical structure. This left-larger-right-smaller conical structure facilitates the smooth pulling of the film roll from the frame, thus improving film collection efficiency. Attached Figure Description

Detailed Implementation

[0026] The following will describe specific embodiments and appendices. Figure 1-8 The technical solutions in the embodiments of the present invention are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of the present invention, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] This invention provides a self-propelled tobacco ridge film removal machine (e.g. Figure 1 As shown, the machine includes an engine 1, a traveling reducer 2, a traveling mechanism, a film-picking mechanism, and a film-winding mechanism. Engine 1 and traveling reducer 2 are both well-known and mature technologies in this field; therefore, their working principles and detailed structures will not be described in detail. In this specific embodiment, engine 1 can be a commercially available gasoline engine. Engine 1, traveling reducer 2, film-picking mechanism, and film-winding mechanism are all mounted on the traveling mechanism. Utilizing the traveling mechanism's ability to move, the machine can easily move automatically above the tobacco ridge. The film-picking mechanism includes a square film-picking frame 41, which can rotate freely. When the film passes over the square film-picking frame 41, the clockwise rotation of the frame causes the film to vibrate up and down, thus facilitating... The soil clods on the film are shaken off. The film winding mechanism includes a cylindrical film winding frame 51, which can rotate freely. The free rotation of the cylindrical film winding frame 51 enables the film to be collected in a concentrated manner. The square film picking frame 41 is adjacent to the film entry side of the cylindrical film winding frame 51. That is, the film on the tobacco ridge needs to be shaken by the square film picking frame 41 before entering the cylindrical film winding frame 51. The cylindrical film winding frame 51 can be transformed into a conical structure. When the cylindrical film winding frame 51 is transformed into a conical structure, it is easier to detach the film rolls wound on the cylindrical film winding frame 51, thereby improving the film collection efficiency. The engine 1 can provide walking power for the walking mechanism and rotational power for the square film picking frame 41 and the cylindrical film winding frame 51. In practical applications, the square film-picking frame 41 can be composed of three support rods and two square plates. The three support rods are distributed in the same plane, and their corresponding ends are fixedly connected by a square plate. When the square film-picking frame 41 and the cylindrical film winding frame 51 are installed on the traveling mechanism, the height of the square film-picking frame 41 can be slightly lower than the height of the cylindrical film winding frame 51. This ensures that when the square film-picking frame 41 is in a vertical position, the height of its highest point is between the height of the rotation axis of the cylindrical film winding frame 51 and the height of the lowest edge of the cylindrical film winding frame 51. In this way, during the rotation of the square film-picking frame 41, not only can the film be picked up and down, but also, when the square film-picking frame 41 picks up the film upward, the film between the square film-picking frame 41 and the cylindrical film winding frame 51 can be tightened to a certain extent. This facilitates the tight wrapping of the film on the cylindrical film winding frame 51 and improves the ability of the cylindrical film winding frame 51 to collect the film 103 at one time.

[0028] When covering tobacco ridges with plastic film, to prevent the film from being blown away by strong winds, the sides of the film are usually continuously buried with soil, and a certain amount of soil is piled at intervals on top of the film. When collecting the film using this invention, the shaking action of the square film-lifting frame 41 can shake off the soil covering the top of the film. However, the shaking action of the square film-lifting frame 41 is not ideal for removing the soil continuously covering the sides of the film. During the film removal process, in order to effectively clean the soil on both sides of the film and effectively separate the film from the soil, a film-lifting mechanism is also provided on the film-lifting machine. The film-lifting mechanism is set on the traveling mechanism and located between the traveling reducer 2 and the square film-lifting frame. Between frames 41, during the film removal process, it is ensured that the two sides of the film are separated from the soil first, and then the film is collected in a concentrated manner. The film lifting mechanism includes two film lifting blades 61 arranged opposite each other on the left and right. The two film lifting blades 61 can move up and down reciprocatingly. The engine 1 provides power for the up and down reciprocating motion of the film lifting blades 61. In practical applications, the film lifting blades 61 are located on both sides of the film. The up and down reciprocating motion of the film lifting blades 61, combined with the linear movement of the walking mechanism, achieves the up and down cutting and loosening of the soil on both sides of the film, thereby effectively separating the two sides of the film from the soil. After the two sides of the film are effectively separated from the soil, the film can be easily pulled flexibly, thus avoiding the situation where the film is pulled hard and damages the tobacco seedlings.

[0029] Based on the above embodiments, the specific implementation of the walking mechanism is as follows: The walking mechanism includes a front walking support 31 and a rear walking support 32. The front walking support 31 and the rear walking support 32 are fixedly connected in a detachable manner. The detachability of the front walking support 31 and the rear walking support 32 facilitates the use of the front walking support 31 as a power traction support for other actuators, thereby achieving the purpose of multi-purpose use. The engine 1 and the walking reducer 2 are arranged opposite each other on the front walking support 31. The film lifting mechanism, the square film picking frame 41, and the cylindrical film winding frame 51 are arranged sequentially from front to back on the rear walking support 32. A walking drive mechanism is provided at the lower part of the front walking support 31. In this specific embodiment, a walking drive mechanism is designed... Two specific embodiments of the walking drive mechanism are provided. The first specific embodiment is as follows: A walking drive shaft 21 extending through both sides of the walking reducer 2 is provided at the bottom. The walking drive mechanism also includes a first walking adjustment sleeve and a first walking wheel. The first walking adjustment sleeve is fitted onto the corresponding end of the walking drive shaft 21 and can be adjusted and positioned left and right relative to the walking drive shaft 21. Specifically, several adjustment holes are provided at the end of the walking drive shaft 21, and positioning holes adapted to the adjustment holes are provided on the first walking adjustment sleeve. A pin is used to pass through the positioning hole and the corresponding adjustment hole to achieve adjustment and fixation of the first walking adjustment sleeve. The first walking wheel is fixedly mounted on the... In practical applications, by adjusting the distance between the two first traveling wheels, the two first traveling wheels can move smoothly on both sides of the tobacco ridges of different widths. By controlling the gear of the traveling reduction gearbox 2, the rotational speed of the first traveling wheels can be controlled, thereby controlling the travel speed of the front traveling support 31. In the first specific embodiment of the traveling drive mechanism, the larger the diameter of the first traveling wheel, the greater the ground clearance of the front traveling support, which facilitates the travel of the front traveling support 31 above the tobacco ridges of different heights. However, under the condition that the rotational speed of the cylindrical film winding frame 51 remains constant, as the diameter of the first traveling wheel increases, the travel speed of the front traveling support 31 increases. At this time, film winding... To avoid the problem of looseness or accumulation, which is detrimental to the effective collection of the membrane, and to ensure that the front traveling support 31 has a high ground clearance while preventing its traveling speed from being too fast, a second specific implementation of the traveling drive mechanism is provided. Specifically, the traveling drive mechanism includes a second traveling adjustment sleeve 312, a transmission chain, a second traveling wheel 316, and two transmission protective covers 313. The second traveling adjustment sleeve 312 is fitted onto the corresponding end of the traveling drive shaft 21 and can be adjusted left and right and positioned relative to the traveling drive shaft 21. Specifically, the traveling drive shaft 21 is provided with several adjustment holes, and the second traveling adjustment sleeve 312 is provided with positioning holes.The second travel adjustment sleeve 312 is adjusted and fixed on the travel drive shaft 21 by using a pin through the positioning hole and the corresponding adjustment hole. Two transmission protective covers 313 are fixedly connected relative to each other. An upper sprocket and a lower sprocket are rotatably arranged inside the two transmission protective covers 313. The transmission chain is sleeved on the upper sprocket and the lower sprocket. The second travel wheel 316 is sleeved on the support shaft 315 sleeved in the lower sprocket. The second travel adjustment sleeve 312 is sleeved inside the upper sprocket. The sleeve 312 can drive the upper sprocket to rotate. The rotation of the upper sprocket drives the lower sprocket to rotate via the transmission chain. The rotation of the lower sprocket drives the support shaft 315 to rotate. The rotation of the support shaft 315 drives the second traveling wheel 316 to rotate. A spacing adjustment sleeve 314 is fixedly installed on the upper outer side of the transmission protective cover 313 near the traveling drive shaft 21, positioned outside the second traveling adjustment sleeve 312. The second traveling adjustment sleeve 312 can rotate freely relative to the spacing adjustment sleeve 314. Specifically, in terms of spacing... A bearing is installed inside the adjusting sleeve 314. The second travel adjusting sleeve 312 is fitted onto the bearing of the spacing adjusting sleeve 314. The bearing supports the rotation of the second travel adjusting sleeve 312 relative to the spacing adjusting sleeve 314. The spacing adjusting sleeve 314 is fitted onto a fixed support sleeve 311 fixedly installed on the front travel bracket 2. To facilitate the rotation of the second travel adjusting sleeve 312, a bearing is installed at the end of the fixed support sleeve 17 away from the transmission protective cover 313. To facilitate the movement and positioning of the spacing adjustment sleeve 314 relative to the fixed support sleeve 311, two pressing bolts are provided on the side wall of the fixed support sleeve 311. The pressing bolts are used to press the spacing adjustment sleeve 314 to achieve its positioning. To fix the fixed support sleeve 311, a support connecting rod is provided between the two fixed support sleeves 311. The support connecting rod is fixedly connected to the front traveling bracket. At the same time, the support connecting rod realizes the fixed connection of the two fixed support sleeves 311. In this specific embodiment, the transmission protective cover is used to achieve the height support of the front traveling bracket 2, thereby increasing its ground clearance. Simultaneously, the transmission chain is used to achieve constant speed transmission from the traveling drive shaft 21 to the second traveling wheel 316. With a reasonable diameter for the second traveling wheel 316, the reasonable traveling speed of the traveling bracket 2 can be controlled. A traveling driven wheel 323 is provided on both sides of the rear of the rear traveling bracket 32. The traveling driven wheel 323 can be adjusted vertically and fixed relative to the rear traveling bracket 32. Specifically, two second vertical sleeves 321 are provided at the rear of the rear traveling bracket 32, arranged horizontally opposite each other. A second adjusting rod 322 is fitted inside the second vertical sleeve 321. The second adjusting rod 322 can move vertically within the second vertical sleeve 321.A pressing bolt is provided on the side wall of the second vertical sleeve 321 to achieve pressing and positioning of the second adjusting rod 322. The driven wheel 323 is fixedly installed at the lower part of the second adjusting rod 322. By adjusting the position of the second adjusting rod 322 within the second vertical sleeve 321, the support height of the driven wheel 323 on the rear traveling bracket 32 ​​can be adjusted.

[0030] Based on the above embodiments, the specific implementation of the mold-lifting mechanism is as follows: The mold-lifting mechanism further includes a first drive shaft 62, which is rotatably mounted on the front traveling bracket 31 along the left-right direction. Specifically, the first drive shaft 62 is sleeved in the bearings of two bearing seats mounted on the front traveling bracket 31. Two eccentric bearings 63 are arranged on the first drive shaft 62 with their left and right sides opposite each other. A first vertical sleeve 64 is fixedly mounted on the lower part of the eccentric bearings 63. A device capable of... The first adjusting rod 65, which moves up and down and is positioned, specifically slides up and down within the first vertical sleeve 64. A pressing bolt is provided on the side wall of the first vertical sleeve 64. The pressing bolt applies pressure to the first adjusting rod 65, thereby adjusting and positioning it within the first vertical sleeve 64. An adjusting frame 66 is provided at the lower part of the first adjusting rod 65, and the mold-lifting knife 61 is mounted on the corresponding adjusting frame 66. The rotation of the first drive shaft 62 drives the rotation of the eccentric bearing 63, thus ultimately realizing the adjustment and positioning of the mold-lifting knife 61. The film-lifting knife 61, through its reciprocating up-and-down motion, can slide and be positioned left and right on the corresponding adjusting frame 66. This left-and-right adjustment capability allows the two film-lifting knives 61 to adapt to tobacco ridges of different widths, effectively facilitating the separation of the film from the soil on both sides of the ridge. Specifically, the upper sleeve of the film-lifting knife 61 is fitted onto the adjusting frame 66, and the sleeve can slide left and right relative to the adjusting frame 66. A pressure bolt is installed on the sleeve, pressing it against the adjusting frame 66. The film-lifting blade 61 is adjusted and positioned so that it can smoothly cut into the soil. The film-lifting blade 61 is arranged in an inclined state with the front lower and the back higher. In order to achieve stable up-and-down reciprocating movement of the film-lifting blade 61, a first vertical fixing rod is set in front of each first vertical sleeve 64. The upper part of the first vertical fixing rod is fixedly connected to the rear walking bracket 32, and a swing limiting rod 67 is hinged to the lower part of the first vertical fixing rod. The other end of the swing limiting rod 67 is hinged to the outer wall of the corresponding first vertical sleeve 64.

[0031] Based on the above embodiments, the specific implementation of the square film-picking frame 41 being rotatably mounted on the rear traveling support 32 is as follows: the square film-picking frame 41 is rotatably mounted on the rear traveling support 32 along the left and right directions. Specifically, the supporting shafts at both ends of the square film-picking frame 41 are sleeved in the bearings of two bearing seats provided on the rear traveling support 32. A first drive gear 42 is provided at the left end of the square film-picking frame 41, and a second drive gear 43 that meshes with the first drive gear 42 is provided on the rear traveling support 32. A first sprocket 44 coaxial with the second drive gear 43 is provided on one side of the second drive gear 43. The rotation of the first sprocket 44 realizes the rotation of the square film-picking frame 41.

[0032] Based on the above embodiments, the specific implementation of the cylindrical film winding frame achieving rotational setting and conical deformation on the rear traveling support 32 is as follows: The cylindrical film winding frame 51 includes a rotating support shaft 511. The left end of the rotating support shaft 511 is sleeved in a bearing seat of the rear traveling support 32, and the right end of the rotating support shaft 511 is rotated and supported by two bearings 324 distributed front and rear. A worm gear reducer 52 is fixedly installed on the rear right side of the rear traveling support 32. The worm gear reducer 52 is a mature technology product in the prior art, therefore... The structure of the worm gear reducer 52 will not be described in detail. The power output end of the worm gear reducer 52 and the rotating support shaft 511 are connected by a bevel gear transmission. Specifically, a second bevel gear 522 is provided at the power output end of the worm gear reducer 52, and a first bevel gear 5111 meshing with the second bevel gear 522 is fixedly provided on the rotating support shaft 511. The rotation of the second bevel gear 522 drives the rotation of the rotating support shaft 511. A second sprocket 5112 is provided at the left end of the rotating support shaft 511. A large circular plate 512 is fixedly installed at the left end of the rotating support shaft 511, and a small circular plate 513 is sleeved on the right end of the rotating support shaft 511. The small circular plate 513 can slide freely and be positioned on the rotating support shaft 511. Specifically, a sleeve is installed on the right side of the small circular plate 513, and the sleeve is fitted onto the rotating support shaft 511. The sleeve can drive the small circular plate 513 to slide left and right on the rotating support shaft 511. A pressing bolt is installed on the sleeve. After the pressing bolt presses against the rotating support shaft 511, the small circular plate 513 is positioned on the rotating support shaft. Positioning on 511, a plurality of groups of retractable rod assemblies are provided between the large circular plate 512 and the small circular plate 513, which are evenly distributed along the circumferential direction of the rotation support shaft 511. Each group of retractable rod assemblies includes a first support rod 514 and a first folding rod 515. The left end of the first support rod 514 is hinged to the right side wall of the large circular plate 512, the inner end of the first folding rod 515 is hinged to the right side wall of the small circular plate 513, and the right end of the first support rod 514 is hinged to the left side wall of the outer end of the first folding rod 515.During the film wrapping process using multiple first support rods 514, the first folding rods 515 are placed vertically. When it is necessary to pull the film roll wrapped around the outside of the multiple first support rods 514 out for cleaning, the small circular plate 513 can be pushed to move it continuously to the left. As the small circular plate 513 moves to the left, the outer ends of the multiple first folding rods 515 will swing to the right synchronously. As the first folding rods 515 swing to the right, the right ends of the multiple first support rods 514 are rotated towards the support shaft 51. The convergence of the first support rods 514 transforms the cylindrical structure into a tapered structure, wider on the left and narrower on the right. After deformation, the film roll loosens, significantly reducing friction between it and the first support rods 514, facilitating easy pulling of the film roll from the right side and enabling rapid cleaning and collection. Furthermore, to prevent the two bearings 324 from obstructing the rightward movement of the film roll during its pulling process, the two bearings 324 are mounted on a cantilever rod 325. The front end of the cantilever rod 325 is connected via a... Page 3251 is hinged to one support end of the rear travel bracket 32. The cantilever rod 325 can swing up and down relative to the rear travel bracket 32. A first swing rod 326 is hinged to the lower part of the cantilever rod 325. A second vertical fixing rod 328 adjacent to the first swing rod 326 is provided at the lower part of the rear travel bracket 32. A second swing rod 327 is hinged to the lower part of the second vertical fixing rod 328. The other end of the first swing rod 326 is hinged to the other end of the second swing rod 327. A limiting block 3271 is fixedly installed at the front end of the swing rod 327 above the first swing rod 326. The limiting block 3271 is located behind the hinge connection between the first swing rod 326 and the second swing rod 327. When the upper side wall of the first swing rod 326 presses against the lower part of the limiting block 3271, the included angle between the first swing rod 326 and the second swing rod 327 is between 140° and 170°. In this specific embodiment, the included angle between the first swing rod 326 and the second swing rod 327 is set to 160°.When the cantilever 325 is in a horizontal state, the swing of the first swing rod 326 towards the second swing rod 327 is limited by the limiting block 3271, thereby locking the rotation of the first swing rod 326 and the second swing rod 327. This allows the first swing rod 326 and the second swing rod 327 to support the cantilever 325, which in turn allows the two bearings 324 to stably support the right end of the rotating support shaft 511. When it is necessary to remove the film roll, the hinge of the first swing rod 326 and the second swing rod 327 is pushed upwards at an angle, thereby releasing the limiting lock of the first swing rod 326 and the second swing rod 327. This allows the rear end of the cantilever 325 to swing downwards. After the cantilever 325 swings downwards to its final position, there are no obstructions at the right end of the rotating support shaft 511, making it easier to pull out the film roll.

[0033] In this specific embodiment, the engine is used to transmit power to the traveling reducer, the film-forming mechanism, the film-picking mechanism, and the film winding mechanism as follows: the engine 1 is a gasoline engine; a first pulley 11 is provided at the power output end of the gasoline engine; a second pulley 21 and a third pulley 22 are coaxially distributed at the power input end of the traveling reducer 2; a fourth pulley 621 and a fifth pulley 622 are respectively provided at the middle and left end of the first drive shaft 62; and a sixth pulley is provided at the power input end of the worm gear reducer 52. A drive belt 101 is fitted between the first pulley 11 and the second pulley 21, between the third pulley 22 and the fourth pulley 621, and between the fifth pulley 622 and the sixth pulley 521. A drive chain 102 is fitted between the first sprocket 44 and the second sprocket 5112. When the engine 1 is started, the power transmission through each drive belt 101 enables the rotation of the walking drive shaft 21, the first drive shaft 62, the square film-picking frame 41, and the rotating support shaft 511, thereby facilitating the lifting and collection of the film 103.

[0034] This invention also provides a method for collecting tobacco ridge film, which includes the self-propelled tobacco ridge film-lifting machine described above. The method further includes the following film collection steps: The entire film-lifting machine is moved above one end of the tobacco ridge. When the front travel support 31 and the rear travel support 32 are moved above the tobacco ridge, the two first travel wheels 316 and the two driven travel wheels 323 are symmetrically distributed on both sides of the tobacco ridge. Then, the film-lifting blades 61 on the left and right sides are adjusted so that they are located on both sides of the bottom of the tobacco ridge. Specifically, the left and right positions of the film-lifting blades 61 are adjusted by moving them on the adjusting frame 66, so that the film-lifting blades 61 correspond to the sides of the film 103. The height of the film-lifting blades 61 is adjusted by moving the first adjusting rod 65 up and down, so that the film-lifting blades 61 can penetrate into the soil at their lowest position. One end of the film 103 below the film-lifting machine is pulled up, so that the film... The free end of 103 first passes over the top of the square film-picking frame 41 and then wraps around and fixes itself to the columnar film-wrapping frame 51 from the bottom. As the film-unwrapping machine moves along the tobacco ridge, looking at the film-unwrapping machine from the left, the columnar film-wrapping frame 51 rotates counterclockwise and the square film-picking frame 41 rotates clockwise. By continuously rotating the square film-picking frame 41 clockwise, the film 103 can be shaken up and down. During the shaking of the film 103, it is beneficial to shake off the soil clods adhering to the upper part of the film, thereby preventing soil clods from being trapped in the collected film roll. At the same time, as the square film-picking frame 41 lifts the film 103 upward, it is beneficial to tighten the film 103 between the square film-picking frame 41 and the columnar film-wrapping frame 51, thereby facilitating the tight wrapping of the film 103 on the columnar film-wrapping frame 51, so that the columnar film-wrapping frame 51 can collect more film at once.

[0035] In this invention, "upper," "lower," "front," "back," "left," and "right" are all relative positions used for the convenience of describing positional relationships, and therefore cannot be understood as absolute positions as limitations on the scope of protection.

[0036] Except for the technical features described in the specification, all other technologies are known to those skilled in the art.

[0037] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. For those skilled in the art, several improvements and modifications can be made without departing from the concept of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
