Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and more specifically, to a hydraulically driven film rolling and automatic film collection and unloading device. Background Technology

[0002] Mulching technology offers significant advantages such as warming and moisture retention, weed control, and increased yield and efficiency, and is widely used in agricultural production in arid areas of northern my country. However, traditional polyethylene mulch film is difficult to degrade naturally after its function is complete. Long-term mulching leads to increasingly serious soil pollution from residual film. Film fragments form a barrier layer in the soil, hindering the flow of water, air, and fertilizer, causing soil compaction, and harming crop growth. In recent years, side-seeding technology using mulch film has been gradually promoted and applied. This technology transforms the conventional "planting on the film" into "planting on both sides of the film," meaning that crop roots avoid the mulch-covered area during sowing, effectively preventing seedling loss caused by misplaced planting holes and soil compaction, while also creating favorable conditions for later residual film recycling. However, existing residual film recycling equipment still suffers from several technical shortcomings: First, the existing film-winding rollers use an integral structure, resulting in heavy bundles of film that adhere tightly to the roller surface, making manual unloading difficult and severely impacting operational efficiency. Second, the recycled film surface is covered with a large amount of soil clods, straw, and other debris, resulting in a high impurity rate and hindering the resource-based reuse of the residual film. Third, the existing devices lack effective coordination between various processes, making it difficult to achieve continuous and efficient automated operation, resulting in low overall operational efficiency. Therefore, it is necessary to provide a hydraulically driven film-winding and automatic film collection and unloading device to address the problems mentioned in the background section.

[0052] Compared with the prior art, the beneficial effects of the present invention are:

[0053] In this invention, the mulch film is separated from the ground surface and lifted upwards from both sides by a side-lifting mechanism, which reduces the amount of soil clods attached to the mulch film. Furthermore, the use of side-seeding on the mulch film fundamentally solves the bottleneck problem of "cloth locking" for crops with large root stubble.

[0054] The rotary cutting cleaning component drives the cleaning cutter to rotate cyclically and cut into the interface between the film surface and the attached material, peeling off soil clods and straw from the film surface. The peeling efficiency is high and the blunt round blade does not puncture the mulch film.

[0055] The upper rollers on both sides drive the batting arc blades to strike the upper surface of the plastic film on both sides in sequence, shaking off the residual fine soil particles and dust, forming a two-stage cleaning gradient of "rotary cutting coarse cleaning + batting fine cleaning", which effectively reduces the impurity content of the recycled plastic film.

[0056] By extending the film winding rack during film winding as a winding skeleton to make the film roll tight and neat, and retracting it during film unloading to make room, the flexible switching between framed film winding and frameless film unloading is realized, ensuring the integrity of the film roll and the smoothness of film unloading.

[0057] By keeping the positioning shaft of the film unloading assembly in an axial position while the film roll assembly separates to both sides, the film roll naturally falls into the collection basket under the action of gravity, achieving fully automatic film unloading without the need for manual assistance.

[0068] Please see Figures 1-9 In this embodiment of the invention, a hydraulically driven film winding and automatic film collection and unloading device includes:

[0069] The vehicle body 1 is equipped with a towing frame 2, which is connected to a power vehicle;

[0070] Side-opening mechanism 3 is fixed to the front end of vehicle body 1;

[0071] The peeling and cleaning device 4 is installed inside the vehicle body 1, located behind the side peeling mechanism 3;

[0072] The beat-and-remove device 5 is fixed on the vehicle body 1 and located behind the stripping and cleaning device 4.

[0073] The film unloading device 6 is fixed at the rear end of the vehicle body 1 and corresponds to the beater and impurity removal device 5.

[0074] The collection basket 7 is located at the bottom of the film unloading device 6.

[0075] In a preferred embodiment, the power vehicle drives the vehicle body 1 forward via the traction frame 2. The side-lifting mechanism 3 is located at the front end of the vehicle body 1 and first contacts the plastic film in the field, separating the plastic film from the ground from both sides and lifting it upwards. The peeling and cleaning device 4 receives the plastic film delivered by the side-lifting mechanism 3 and performs rotary cutting and peeling to clean the soil clods, straw, and other attachments on the surface of the plastic film. The beating and impurity removal device 5 beats and removes residual small impurities from the plastic film after peeling and cleaning. The film roll unloading device 6 rolls the clean plastic film into a bundle and automatically unloads the film after it reaches the set size. The unloaded film roll falls into the collection basket 7 at the bottom. It should be noted that this device is suitable for plastic film recycling under the plastic film side-seeding technology. If there is a problem with the plastic film conveying, in the initial stage, the plastic film can be manually guided to the film roll unloading device 6 to ensure the overall operation.

[0076] In this embodiment, the side-opening mechanism 3 includes:

[0077] The guiding diaphragm 31 is tilted and fixed to the front end of the vehicle body 1;

[0078] Two side-opening plates 32 are symmetrically distributed and inclined inward, and are movable on the guide film-raising plate 31;

[0079] Adjustment component 33 is provided corresponding to side panel 32 and connects the outer side of side panel 32 and the inner wall of vehicle body 1.

[0080] In other words, before the operation begins, the operator adjusts the position of the side flaps 32 on the guide film plate 31 using the adjusting component 33 according to the actual width of the mulch film. When the adjusting component 33 extends, it pushes the side flaps 32 inward, reducing the distance between the two side flaps 32, which is suitable for narrower mulch films. When the adjusting component 33 shortens, it pulls the side flaps 32 outward, increasing the distance between the two side flaps 32, which is suitable for wider mulch films. When the vehicle body 1 moves forward, the side flaps 32 on both sides wedge into the interface between the mulch film and the ground surface from below the edges of the mulch film. The side flaps 32 are tilted inward, with their front end lower and their rear end higher. During the process, the plastic film is gradually scooped up and gathered from both sides, so that the edges of the plastic film, which was originally laid flat on the ground, are lifted off the ground and raised. The lifted plastic film slides backward along the upper surface of the side lifting plate 32 and enters the upper surface of the guide lifting plate 31. The guide lifting plate 31 supports the lifted plastic film from below and smoothly guides it into the peeling and cleaning device 4 at the rear. At the same time, during this process, the relative position between the side lifting plate 32 and the guide lifting plate 31 remains fixed. The side lifting plate 32 slides above the guide lifting plate 31. The gap between the two allows the plastic film to pass through but does not allow large clods of soil to pass through, which plays a preliminary screening role.

[0081] In this embodiment, the peeling and cleaning device 4 includes:

[0082] The circulating conveying mechanism 41 is inclinedly installed inside the vehicle body 1, with its front end corresponding to the side lifting mechanism 3 and its rear end corresponding to the beater and impurity removal device 5;

[0083] Two adjustable robotic arms 42 are symmetrically distributed and fixed on the inner wall of the vehicle body 1, and located above the circulating conveying mechanism 41.

[0084] The rotary cutting and cleaning component 43 is correspondingly set on the adjusting robotic arm 42 and fixed on the adjusting robotic arm 42.

[0085] In other words, the plastic film delivered by the side-opening mechanism 3 reaches the front end of the circulating conveying mechanism 41. The circulating conveying mechanism 41 is set at an angle (lower at the front end and higher at the rear end), and its surface is a ring conveyor belt. Driven by the drive roller, it rotates from front to back, conveying the plastic film backward and upward along the inclined direction. During the conveying process, the plastic film passes under the adjusting mechanical arm 42 and the rotary cutting and cleaning component 43. The adjusting mechanical arm 42 is a multi-joint adjustable mechanical arm that can be raised and lowered and swung left and right. Before the operation, the operator adjusts the height and left and right position of the rotary cutting and cleaning component 43 by adjusting the mechanical arm 42 according to the thickness of the plastic film and the condition of the surface debris. This ensures that the bottom of the rotary cutting and cleaning component 43 is close to the surface of the plastic film but with a small gap, so that the cleaning component can act on the film surface attachments but will not compact the plastic film or hinder the conveying of the plastic film.

[0086] In a preferred embodiment, the rotary cutting and cleaning components 43 on both sides can be arranged in a staggered manner, with the left rotary cutting and cleaning component 43 located in front and the right rotary cutting and cleaning component 43 located behind. The two are staggered by a distance in the front-back direction, so that the left rotary cutting and cleaning component 43 cleans the left side area of ​​the mulch film first, and the right rotary cutting and cleaning component 43 cleans the right side area of ​​the mulch film afterward, avoiding spatial interference between the two rotary cutting and cleaning components 43; the surface of the conveyor belt of the circulating conveying mechanism 41 is mesh-like or has transverse spacers, which facilitates the falling of soil clods, straw and other debris from the gaps or edges of the conveyor belt to the bottom of the vehicle body 1, thereby separating them from the mulch film.

[0087] In this embodiment, the rotary cutting and cleaning component 43 includes:

[0088] The outer casing 431 is connected to the drive motor inside. The top center is fixedly connected to the adjusting mechanical arm 42, the bottom corresponds to the top of the circulating conveying mechanism 41, and the side is provided with an annular groove that connects the inside and outside.

[0089] The drive gear 432 is rotatably disposed at both ends inside the connecting housing 431 and is driven by a drive motor.

[0090] The transmission chain 433 is mounted on the drive gear 432;

[0091] Cleaning cutters 434 are provided in multiples along the transmission chain 433 and fixed on the outside of the transmission chain 433, corresponding to the annular groove on the side of the connecting housing 431.

[0092] In other words, the connecting housing 431 is positioned at a certain height above the circulating conveying mechanism 41 by adjusting the mechanical arm 42. The mulch film passes through the gap between the bottom of the connecting housing 431 and the circulating conveying mechanism 41. After the drive motor starts, it drives the drive gear 432 to rotate. When the drive gear 432 rotates, the transmission chain 433 rotates in a cycle. The cleaning cutter 434 moves in a cycle along with the transmission chain 433. The cleaning cutter 434 extends out through the annular groove on the side of the connecting housing 431 and contacts the attachments on the surface of the mulch film. It cuts into the interface between the mulch film surface and the attachments. Since the direction of the cycle of the transmission chain 433 is opposite to (or at a certain angle to) the conveying direction of the mulch film, the cleaning cutter 434 generates a tangential shearing force on the attachments, peeling soil clods, straw, etc. from the film surface. The blade of the cleaning cutter 434 is a blunt round blade, which can cut into the bottom of the attachments without piercing the mulch film. After the attachments are peeled off, they fall from the mesh or gaps of the circulating conveying mechanism 41.

[0093] In this embodiment, the tapping and impurity removal device 5 includes:

[0094] Two support seats 51 are symmetrically distributed and fixed to the vehicle body 1;

[0095] The lower striking roller 52 is rotatably mounted between the support bases 51 and corresponds to the rear end of the stripping and cleaning device 4;

[0096] There are two upper tapping rollers 53 arranged in a straight line, located on the top sides of the lower tapping roller 52, and their ends are rotatably connected to the support base 51.

[0097] There are two sets of slapping arc blades 54 corresponding to the upper slapping roller 53. Each set has multiple blades arranged in a ring. Each slapping arc blade 54 is axially arranged and its root is hinged to the side wall of the upper slapping roller 53.

[0098] In other words, the plastic film cleaned by the stripping and cleaning device 4 is output from the rear end of the circulating conveying mechanism 41 and enters the beating and impurity removal device 5. The plastic film moves along the upper surface of the lower beating roller 52. The lower beating roller 52 is a smooth rubber roller that supports the plastic film from below and passively rotates with the movement of the plastic film, playing a supporting and conveying role. The two upper beating rollers 53 are independently driven to rotate by hydraulic motors. When the upper beating rollers 53 rotate, the beating arc plates 54 installed on their side walls rotate accordingly. When a certain beating arc plate 54 rotates to the lowest position (i.e., close to the plastic film), the beating arc plate... The outer protrusion of 54 strikes the upper surface of the mulch film, shaking off residual fine soil particles and dust. After the strike is completed, the striking arc 54 continues to rotate away from the lowest position with the upper striking roller 53, preparing for the next strike. Under the tension of the mulch film, the striking arc 54 contracts under force and returns to its original position after detaching from the mulch film, effectively avoiding damage to the mulch film. The two upper striking rollers 53 achieve full coverage of the mulch film in the width direction. The fine soil particles and dust shaken off fall under the action of gravity and fall from the sides or gaps of the lower striking roller 52 to the bottom of the vehicle body 1.

[0099] In this embodiment, the film unloading device 6 includes:

[0100] Positioning bases 61 are provided in two symmetrically distributed locations and are fixed to the inner ends of the collection basket 7;

[0101] The control seat 62 is fixed on the positioning base 61;

[0102] The drive control mechanism 63 is mounted on the control seat 62 and is hydraulically driven.

[0103] Two film winding assemblies 64 are symmetrically distributed, and their outer ends are fixedly connected to the corresponding drive control mechanism 63.

[0104] The film unloading assembly 65 is correspondingly provided with the film winding assembly 64. Its outer side is rotatably connected to the top of the positioning base 61, and its inner side is slidably connected to the film winding assembly 64.

[0105] In other words, in the film winding operation state, the two film winding assemblies 64 are closed, and the film is wound into a bundle on the two film winding assemblies 64. In the film unloading state, the drive control mechanism 63 drives the two film winding assemblies 64 to separate to both sides, and the film unloading assembly 65 remains stationary, peeling the film roll off the film winding assembly 64.

[0106] In this embodiment, the drive control mechanism 63 includes:

[0107] The drive connector 631 is movably mounted on the adjustment groove 632 on the top of the control seat 62, and the drive connector 631 is equipped with two independent hydraulic motors.

[0108] The limiting plate 633 is fixed to one end of the adjusting groove 632 near the outer side, corresponding to the outer side of the drive connector 631;

[0109] The outer drive shaft 634 is fixedly connected to the hydraulic motor of the drive connector 631, and the other end is fixedly connected to the end of the film winding assembly 64.

[0110] The inner drive shaft 635 is coaxially arranged with the outer drive shaft 634 and connected to another hydraulic motor.

[0111] In other words, the drive connector 631 is installed on the adjustment groove 632 on the top of the control seat 62, and can reciprocate along the length direction of the adjustment groove 632 (i.e., the width direction / left-right direction of the vehicle body 1). The drive connector 631 is equipped with two independent hydraulic motors, motor one and motor two. The output shaft of motor one is connected to the drive outer shaft 634, and the other end of the drive outer shaft 634 is fixedly connected to the outer end of the film winding assembly 64. The output shaft of motor two is connected to the drive inner shaft 635, and the drive inner shaft 635 is coaxially arranged with the drive outer shaft 634. The other end of the drive inner shaft 635 extends into the interior of the film winding assembly 64. The limiting plate 633 limits the outward movement limit position of the drive connector 631 to prevent the drive connector 631 from slipping off the adjustment groove 632. In the film winding operation state, the drive connector 631 Located inside the adjustment groove 632 (where the two film roll assemblies 64 are closed), Motor 1 drives the film roll assembly 64 to rotate as a whole via the drive outer shaft 634, and Motor 2 drives the film roll assembly 64 to adjust internally via the drive inner shaft 635 before stopping. In the unloading state, Motor 2 first controls the internal adjustment of the film roll assembly 64 via the drive inner shaft 635, and then drives the connecting piece 631 to move outward along the adjustment groove 632 (pushed by a hydraulic cylinder) until it contacts the limit plate 633 and stops. During the movement, the drive outer shaft 634 and drive inner shaft 635 move outward accordingly, driving the film roll assembly 64 to move outward, causing the film roll to detach from the film roll assembly 64. After the film unloading is completed, the drive connecting piece 631 moves inward along the adjustment groove 632 to reset, and the two film roll assemblies 64 close again.

[0112] In this embodiment, the film winding assembly 64 includes:

[0113] Two polygonal planes 641 are symmetrically distributed and set at both ends of the film winding assembly 64. The center of the outer polygonal plane 641 is fixedly connected to the drive outer shaft 634. The polygonal plane 641 is composed of multiple long sides and short sides spaced apart.

[0114] The connecting surface 642 is provided in a ring-shaped arrangement with multiple connections, which connect the long sides of two polygonal planes 641 and form a gap between the short sides.

[0115] An arc-shaped body 643 is provided corresponding to the connecting surface 642 and is fixed on the outside of the connecting surface 642;

[0116] Multiple film-winding racks 644 are arranged in a ring and are movably disposed in the interval grooves between the connecting surfaces 642;

[0117] Two adjustment mechanisms 645 are symmetrically distributed and fixed on the inner side of the polygonal plane 641, and the center of the adjustment mechanism 645 is connected to the inner drive shaft 635.

[0118] In other words, when the inner drive shaft 635 rotates forward, the adjusting mechanism 645 pushes the film-winding rack 644 to move radially outward, so that the outer end of the film-winding rack 644 extends beyond the outside of the arc-shaped body 643. The diameter of the circumscribed circle formed by the outer end of the film-winding rack 644 is larger than the diameter of the circumscribed circle formed by the arc-shaped body 643. At this time, the film-winding rack 644 serves as the winding skeleton of the mulch film, and the mulch film is wound on the outer surface of the film-winding rack 644. When the inner drive shaft 635 rotates in reverse, the adjusting mechanism 645 pulls the film-winding rack 644 to move radially inward, and the film-winding rack 644 retracts into the spacer groove, with its outer end not exceeding the outer surface of the arc-shaped body 643. At this time, the inner surface of the film roll originally wound on the film-winding rack 644 contacts the arc-shaped body 643 and is supported by the arc-shaped body 643.

[0119] In a preferred embodiment, during the film winding process, the drive outer shaft 634 drives the entire film winding assembly 64 to rotate through the polygonal plane 641. The film is wound into a bundle on the outer surface of the film winding rack 644. During the film unloading process, after the film winding rack 644 retracts, the film roll is only supported by the arc-shaped body 643. When the film winding assembly 64 separates to both sides, the film roll slips off the arc-shaped body 643.

[0120] In this embodiment, the adjustment mechanism 645 includes:

[0121] Fixed slide rails 6451 are arranged in a ring and fixed on the inner side of polygonal plane 641. The drive inner shaft 635 passes through the center of the multiple fixed slide rails 6451 and is rotatably connected to the center of the multiple fixed slide rails 6451.

[0122] A rotating circular surface 6452 is disposed on the inner side of the fixed slide rail 6451 and is fixedly connected to the drive inner shaft 635. The rotating circular surface 6452 is provided with an arc-shaped slide rail 6453 corresponding to the fixed slide rail 6451.

[0123] The movable slider 6454 is slidably disposed within the fixed slide rail 6451 and the arc-shaped slide rail 6453, and its end is fixedly connected to the end of the film rolling rack 644.

[0124] In other words, when the inner shaft 635 rotates clockwise, the rotating circular surface 6452 rotates clockwise as well, and the arc-shaped slide 6453 rotates accordingly. Since the fixed slide 6451 is fixed, the movable slider 6454 can only slide radially under the restriction of the fixed slide 6451. However, under the push of the arc-shaped slide 6453, the movable slider 6454 slides outward (away from the center) along the fixed slide 6451. Under the combined action of the two adjustment mechanisms 645, the film-winding rack 644 is pushed outward. When the inner drive shaft 635 reverses, the rotating circular surface 6452 also reverses, and the arc-shaped slide 6453 rotates in the opposite direction, pushing the movable slider 6454 to slide inward (near the center) along the fixed slide 6451, pulling the film roll rack 644 inward to retract; when the inner drive shaft 635 does not rotate, the rotating circular surface 6452 remains stationary, the movable slider 6454 remains in a fixed position in the fixed slide 6451 and the arc-shaped slide 6453, and the film roll rack 644 maintains its current extended or retracted state.

[0125] In this embodiment, the film removal assembly 65 includes:

[0126] The limiting ring 651 is rotatably connected to the top of the positioning base 61 on its outer side;

[0127] The positioning shafts 652 are arranged in a ring, with multiple shafts. The outer end is fixed to the inner side of the limiting ring 651, and the inner end corresponds to the gap groove between the connecting surface 642.

[0128] In other words, during the film winding process, the film winding assembly 64 rotates under the drive of the outer drive shaft 634. Since the inner end of the positioning shaft 652 extends into the spacer groove of the film winding assembly 64, when the film winding assembly 64 rotates, the side wall of the spacer groove pushes the positioning shaft 652, thereby causing the limiting ring 651 to rotate with the film winding assembly 64. At this time, there is no relative sliding between the positioning shaft 652 and the film winding assembly 64, which is equivalent to the unloading assembly 65 rotating synchronously with the film winding assembly 64. During the unloading process, the film winding assembly 64 moves outward (axially) under the drive of the drive connector 631. At this time, the film winding rack 644 has retracted towards the center and will not obstruct the positioning shaft 652. The inner end of the positioning shaft 652 still extends into the spacer groove, but since the outer side of the limiting ring 651 is rotatably connected to the positioning base 61 (only... (Rotational, non-axially movable) The limiting ring 651 and the positioning shaft 652 remain in the same position in the axial direction. When the film roll assembly 64 moves outward, the spacer groove slides outward relative to the positioning shaft 652. The positioning shaft 652 acts as a blocking element to prevent the film roll from moving outward with the film roll assembly 64. The film roll is limited by the positioning shaft 652 to its original axial position. As the film roll assembly 64 continues to move outward, the film roll gradually detaches from the support of the film roll assembly 64 and falls off the film roll assembly 64 under the action of gravity, falling into the collection basket 7 below. When both sides of the film roll assembly 64 have moved outward a certain distance, the film roll completely detaches from the film roll assembly 64, completing the film unloading. After the film unloading is completed, the drive connector 631 moves inward to reset, the film roll assembly 64 closes inward, and the positioning shaft 652 resets in the spacer groove.

[0129] In practice, before the operation begins, the distance between the side flaps 32 on both sides is adjusted according to the width of the plastic film using the adjusting component 33. During operation, the power vehicle moves the vehicle body 1 forward via the traction frame 2. The side flaps 32 wedge between the plastic film and the ground surface from both sides, scooping the plastic film upward and conveying it along the guide film plate 31 to the circulating conveying mechanism 41. The circulating conveying mechanism 41 conveys the plastic film backward and upward while adjusting the mechanical arm 42 to drive the rotary cutting and cleaning component 43 to move downward so that the cleaning cutter 434 contacts the attachments on the film surface. The drive motor drives the drive gear 432 and the transmission chain 433 to rotate cyclically from... The cleaning cutter 434 extends cyclically from the annular groove on the side of the connecting outer casing 431, cutting into the interface between the film surface and the attached material to peel off soil clods and straw. The peeled debris falls off at intervals through the circulating conveyor mechanism 41. The mulch film continues to enter the beating and impurity removal device 5 and moves along the upper surface of the lower beating roller 52. The upper beating rollers 53 on both sides rotate, driving the beating arc blades 54 to strike the upper surfaces of both sides of the mulch film in sequence, shaking off residual fine soil particles and dust. The cleaned mulch film enters the film unloading device 6. At this time, the drive inner shaft 635 rotates clockwise, driving the rotating circular surface 6452 to rotate, causing the arc-shaped slide 64 to move. 53. Push the movable slider 6454 to slide outward along the fixed slide rail 6451. The two adjusting mechanisms 645 jointly push the film winding rack 644 to extend out of the spacer groove as a winding frame. Then, drive the outer shaft 634 to drive the film winding assembly 64 to rotate, so that the film is wound into a bundle on the outer surface of the film winding rack 644. When the film roll reaches the set diameter, drive the outer shaft 634 to stop rotating, and drive the inner shaft 635 to reverse, so that drive the rotating circular surface 6452 to rotate in the opposite direction, causing the movable slider 6454 to slide inward along the fixed slide rail 6451, pulling the film winding rack 644 back into the spacer groove. At this time, the inner surface of the film roll The film roll contacts the arc-shaped body 643, and then the drive connector 631 moves outward along the adjustment groove 632, causing the two film roll assemblies 64 on both sides to separate outward. The film roll rack 644 has retracted and does not block the positioning shaft 652. The positioning shaft 652 remains unchanged in the axial direction, thus blocking the film roll in its original position. As the film roll assembly 64 moves outward, it gradually loses the support of the arc-shaped body 643 and falls into the collection basket 7 under the action of gravity. After the film is unloaded, the drive connector 631 resets so that the two film roll assemblies 64 close again, and the positioning shaft 652 re-extends into the interval groove to enter the next round of film roll operation.
