Description

Technical Field

[0001] This utility model belongs to the field of residual film recycling technology, and in particular relates to a modular residual film collection and aggregation device. Background Technology

[0002] In agricultural production, mulching can effectively increase soil temperature, suppress weed growth, and improve crop yield and quality. After the mulch is used up, the residual film needs to be recycled promptly. However, the recycling of residual film still relies on manual turning of the film, which is not only labor-intensive but also inefficient and cannot be carried out for extended periods. Existing residual film recycling equipment typically uses traditional flat turning plates, which cause the residual film to move and shift irregularly during the turning process, resulting in entanglement and tearing, forming a large amount of debris. This makes it difficult for the subsequent film conveying structure to effectively transport the residual film debris, which then mixes into the soil, affecting subsequent cultivation. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] This invention provides a modular residual film collection device to solve the following problems:

[0005] 1. Manual film turning is not only labor-intensive but also inefficient, making it impossible to perform film turning work for extended periods.

[0006] 2. During the process of flipping the residual film using a flat film-flipping plate, the residual film will exhibit irregular movement and displacement, causing the residual film to become entangled and torn together, forming a large amount of debris. The subsequent film delivery structure cannot effectively transport these residual film debris, resulting in the residual film eventually mixing back into the ground, leading to poor recycling efficiency.

[0007] (II) Technical Content

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A modular residual film collection device includes two docking brackets, and the same docking main shaft is detachably inserted between the two docking brackets. Multiple unidirectional guiding structures are installed on the docking main shaft. Each unidirectional guiding structure includes multiple film-raising plates. The top of each film-raising plate is provided with an arc-shaped guiding arc surface. The curvature of the guiding arc surface of the multiple film-raising plates on the same unidirectional guiding structure gradually decreases along the same direction.

[0010] Multiple unidirectional guide structures are placed in pairs, and the two unidirectional guide structures in the same group are stacked symmetrically together. The guide arc surfaces of the multiple film-forming plates after stacking together form an inwardly converging guide groove.

[0011] Furthermore, both the docking bracket and the film-forming plate are provided with insertion interfaces that are adapted to the shaft surface of the docking spindle. The two ends of the docking spindle are respectively inserted into the insertion interfaces provided on the two docking brackets. The film-forming plate is sleeved on the docking spindle through the insertion interface. The film-forming plates in the stacked unidirectional guide structure are all located between the two docking brackets.

[0012] Furthermore, threaded rods are integrally fixed to both ends of the docking spindle, and locking nuts are threaded onto each threaded rod, with the docking bracket abutting against the locking nuts.

[0013] Furthermore, the docking bracket is also provided with multiple docking holes.

[0014] Furthermore, at least one docking spindle is provided, and the longitudinal section of the docking spindle is polygonal.

[0015] Furthermore, at least two docking spindles are provided, and the longitudinal section of the docking spindles is circular.

[0016] Furthermore, the guide arc surfaces on the two unidirectional guide structures in the same group are inclined, and the guide arc surfaces are inclined downward along the direction close to the inner converging guide groove.

[0017] Furthermore, the guide arc surfaces of the two unidirectional guide structures in the same group are provided with rounded corners on the side near the inner converging guide groove.

[0018] Furthermore, the film-forming plate is hollow inside.

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] I. In this utility model, the guide arc surface can turn over the residual film and soil in an arc trajectory. While the residual film and soil are turned over, they will also move in a direction along the inclined surface of the guide arc surface, so that the turned-over residual film and soil gradually gather inward to the middle of the guide groove, so that the subsequent film turning structure can convey the turned-over residual film. This avoids the residual film from getting tangled and torn together due to irregular movement and displacement during the turning process, which would form a lot of debris.

[0022] Second, in this utility model, if it is only a simple task of turning the residual film out of the ground, the workers can directly connect with the drive vehicle through the docking hole on the docking bracket, and the drive vehicle will drive the modular residual film collection device to turn the residual film out of the ground.

[0023] Workers can also connect the modular residual film collection device to the residual film recycling equipment through the docking holes on the docking bracket. The modular residual film collection device can then be used to turn over the residual film in the field, and the residual film recycling equipment can separate the turned-over residual film from the soil and recycle the residual film.

[0024] Third, in this utility model, the locking nut can limit the installation of the docking bracket, the film-forming plate and the docking spindle, so as to prevent the docking bracket, the docking spindle and the film-forming plate from becoming loose or separating during use.

[0025] Fourth, in this utility model, workers can adjust the number of unidirectional guiding structures according to the actual ridge spacing to improve the adaptability of the modular residual film collection device.

[0026] Fifth, in this utility model, the rounded corners allow the flipped residual film to smoothly transition from one film-raising plate to another, reducing the scraping between the side of the guide arc surface and the residual film, and preventing the residual film from tearing.

[0027] VI. In this utility model, if it is only to turn over and recycle the residual film buried in the shallow soil layer, the workers can choose a film-lifting plate with a hollow interior, thereby reducing the weight of the modular residual film collection device and reducing the load on the drive vehicle or residual film recycling equipment.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Example 1

[0037] like Figures 1-6 As shown, a modular residual film collection device includes two docking brackets 11, and the same docking main shaft 12 is detachably inserted between the two docking brackets 11. Multiple unidirectional guide structures are installed on the docking main shaft 12. The unidirectional guide structure includes multiple film-raising plates 13. The top of each film-raising plate 13 is provided with an arc-shaped guide arc surface 131. The curvature of the guide arc surface 131 of the multiple film-raising plates 13 on the same unidirectional guide structure gradually decreases along the same direction.

[0038] Multiple unidirectional guiding structures are placed in pairs, and the two unidirectional guiding structures in the same group are stacked symmetrically together. The guiding arc surfaces 131 of the multiple film-forming plates 13 after stacking together form an inner converging guide groove 1301 for guiding the residual film.

[0039] Furthermore, the guide arc surfaces 131 on the two unidirectional guide structures in the same group are inclined, and the guide arc surfaces 131 are inclined downward along the direction close to the inner converging guide groove 1301.

[0040] Furthermore, both the docking bracket 11 and the film-raising plate 13 are provided with insertion interfaces 1101 that are adapted to the shaft surface of the docking spindle 12. During installation, the film-raising plate 13 is first sleeved on the docking spindle 12 through the insertion interface 1101, and then the two ends of the docking spindle 12 are respectively inserted into the insertion interfaces 1101 provided on the two docking brackets 11. The film-raising plates 13 in the stacked unidirectional guide structure are all located between the two docking brackets 11.

[0041] Both ends of the docking spindle 12 are integrally fixed with threaded rods 121, and each threaded rod 121 is threaded with a locking nut 14. After the docking bracket 11, the film-raising plate 13 and the docking spindle 12 are installed, the locking nut 14 is threaded onto the threaded rod 121. After tightening the locking nut 14, the docking bracket 11 and the locking nut 14 abut against each other. The locking nut 14 can limit the installation of the docking bracket 11, the film-raising plate 13 and the docking spindle 12, and prevent the docking bracket 11, the docking spindle 12 and the film-raising plate 13 from loosening or separating during use.

[0042] Workers can install shims between the docking bracket 11 and the locking nut 14 to prevent deformation of the surface of the docking bracket 11 due to excessive local pressure. At the same time, the shims can also play a certain buffering role, which can reduce the loosening of the locking nut 14 caused by vibration during the operation of the device. Workers can also check the locking nut 14 regularly to see if it is loose.

[0043] Among them, staff can adjust the number of unidirectional guiding structures according to the actual ridge spacing to improve the adaptability of the modular residual film collection device.

[0044] The docking bracket 11 is also provided with multiple docking holes 1102. After the docking bracket 11, the film-raising plate 13 and the docking spindle 12 are installed,

[0045] If the task is simply to turn over the residual film from the ground, the workers can directly connect it to the drive vehicle body through the docking hole 1102 on the docking bracket 11.

[0046] Workers can also connect the modular residual film collection device to the residual film recycling equipment through the docking hole 1102 on the docking bracket 11. The modular residual film collection device can be used to turn over the residual film in the field, and the residual film recycling equipment can be used to separate the turned-over residual film from the soil and recycle the residual film.

[0047] Regardless of the type of work involved, when the driving vehicle or the residual film recycling equipment moves the docking bracket 11 forward, the front end of the film lifting plate 13 will penetrate into the ground. As the driving vehicle or the residual film recycling equipment moves forward, the residual film buried in the ground will be turned up.

[0048] In traditional flat film-turning boards, the residual film moves and shifts irregularly during the turning process, causing the residual film to entangle and tear each other, forming a large amount of debris. This makes it impossible for the subsequent film delivery structure to effectively transport the residual film debris, which will mix into the field and affect subsequent cultivation.

[0049] Compared to traditional flat film-turning plates, this application uses a guide arc surface 131 to turn over the residual film and soil in an arc trajectory. As the residual film and soil are turned over, they also move in a direction along the inclined surface of the guide arc surface 131, so that the turned-over residual film and soil gradually gather inward to the center of the guide groove 1301, so that the subsequent film-turning structure can transport the turned-over residual film. This avoids the residual film from tangling and tearing each other due to irregular movement and displacement during the turning process, which would result in a large amount of debris.

[0050] Furthermore, the longitudinal section of the docking spindle 12 is polygonal to prevent the film-forming plate 13 from rotating on the docking spindle 12. At least one docking spindle 12 is provided, and multiple docking spindles 12 can also be provided by the operator to further prevent the film-forming plate 13 from rotating on the docking spindle 12 and improve the stability of the film-forming plate 13 during operation.

[0051] Furthermore, the guide arc surface 131 on the two unidirectional guide structures in the same group is provided with a rounded corner on the side near the inner convergence guide groove 1301. The rounded corner can make the flipped residual film smoothly transition from one film-raising plate 13 to another film-raising plate 13, reducing the scraping between the side of the guide arc surface 131 and the residual film, and preventing the residual film from tearing.

[0052] Example 2

[0053] like Figures 1-6 As shown, this embodiment has been improved on the basis of embodiment one as follows: When installing the film-raising plate 13, the operator can choose a docking spindle 12 with a circular longitudinal section, but at least two docking spindles 12 are set to avoid the film-raising plate 13 rotating on the circular docking spindle 12, which would affect the subsequent film-turning work.

[0054] Example 3

[0055] like Figures 1-6 As shown, this embodiment has been improved on the basis of embodiment one as follows: Furthermore, if it is only to turn over and recycle the residual film buried in the shallow soil layer, the workers can choose the film-lifting plate 13 with a hollow interior, thereby reducing the weight of the modular residual film collection device and reducing the load on the drive vehicle or residual film recycling equipment.

[0056] However, as is well known to those skilled in the art, the working principles and wiring methods of the drive vehicle body and residual film recycling equipment are commonplace and are all conventional methods or common knowledge. Therefore, they will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0057] The different embodiments described above can be combined, substituted, or used in combination with each other.
