Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, specifically to an integrated machine for removing film, cultivating soil, and applying fertilizer. Background Technology

[0002] With the promotion of protected cultivation technology, the area covered by plastic film mulching is also increasing. However, due to the lack of timely and effective recycling of residual film, the amount of residual film in the soil is increasing year by year, seriously affecting crop yields and sustainable agricultural development, and also causing white pollution. Therefore, researching residual film recycling equipment has become the key to further promoting and developing plastic film mulching technology.

[0003] The recovery roller is one of the main working components of the plastic film recycling machine. It mainly completes two operation modes: automatic film winding and film unloading after film lifting. However, in existing equipment, the plastic film on the recovery roller is always in a taut state due to the rotation of the recovery roller. After a long period of recycling, the plastic film on the recovery roller is quite tough, making it inconvenient for personnel to remove and recycle the collected plastic film. To solve this problem, the patent application document with application number CN201521026153.X mentions a seedling stage plastic film recycling roller, which uses a method of "inserting a knife into the square opening between the film winding teeth to cut the plastic film" for convenient removal of the plastic film.

[0004] However, the above-mentioned method of directly cutting the plastic film on the recycling roller is problematic because there are usually other combined operation machines installed in front of and behind the recycling roller. If the worker is standing on the ground, he can only cut the plastic film from the side of the recycling roller. The length of the recycling roller is much greater than the length of a human arm. Without the help of other extended tools, the worker needs to climb onto the machine to cut the plastic film. Since there is usually no place for people to stand on the plastic film recycling machine, there is a certain risk of falling while the worker is on the plastic film recycling machine. Utility Model Content

[0005] This utility model addresses the problems in the prior art by providing an integrated machine for removing, cultivating, and fertilizing mulch film, which facilitates the recycling of mulch film and solves the problem that mulch film is often wrapped too tightly in the prior art, making it difficult to remove.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A mulch film removal, soil covering, and topdressing integrated machine includes a main frame. A soil turning unit is located at the front end of the main frame, and a soil covering unit is located behind the soil turning unit. A recycling unit is also located on the main frame. The recycling unit includes a rotatable main roller mounted on the main frame. A first support plate is located at one end of the main roller, and several auxiliary rollers are hinged to the first support plate. A second support plate is slidably mounted at the other end of the main roller, and the same number of connecting rods as the auxiliary rollers are hinged to the second support plate. The other ends of the connecting rods are hinged to the other ends of the auxiliary rollers and are arranged in a one-to-one correspondence. Through the second support plate and connecting rods, multiple auxiliary rollers are arranged in parallel during mulch film recycling to complete the mulch film winding and recycling. When removing the mulch film, the worker pulls the second support plate, thereby moving several connecting rods. This causes several auxiliary rollers close to the second support plate to move closer to the second support plate, resulting in a state where one end of the recycling unit has a larger diameter and the other end has a smaller diameter. At this point, the worker can easily move the mulch film to the vicinity of the second support plate for removal without needing to climb onto the machine or use auxiliary tools.

[0008] Preferably, a locking unit is fixedly connected to the second support plate, which can limit the relative displacement between the main roller and the second support plate. The locking unit ensures that the recycling system does not require adjustment of the auxiliary roller during operation, thus guaranteeing the stability of the plastic film recycling process.

[0009] Preferably, the locking unit includes a sliding member and a locking member. The sliding member is fixed to the second support plate and has a through hole. The main roller has a first locking hole. One end of the locking member can move through the through hole into the first locking hole. When the locking member is in the first locking hole, several auxiliary rollers are in a parallel state. The locking member and the first locking hole allow for easy manual adjustment of the locking member by the operator.

[0010] Preferably, the drive roller is also provided with a second locking hole. One end of the locking member can move into the second locking hole through the through hole. When the locking member is located in the second locking hole, several auxiliary rollers are in a non-parallel state. With the provision of the second locking hole, when the mulch film is removed, the operator can place the locking member in the second locking hole, thereby achieving stability when the mulch film is removed.

[0011] Preferably, the soil-turning unit includes two soil-turning rollers symmetrically arranged on the main frame. The lower end of the soil-turning rollers is positioned below the mulch film in the soil during operation to turn the mulch film out. By setting two symmetrical soil-turning rollers, the mulch film is turned out of the soil before the mulch film is recycled in the recycling unit, avoiding excessive breakage of the mulch film caused by soil covering, which could affect subsequent planting.

[0012] Preferably, the soil covering unit includes two soil covering components symmetrically arranged on the main frame. The soil covering components are rotatably mounted on the main frame and include a rotating shaft and several soil covering plates. Through the soil covering components, the soil can be promptly returned to its original position after the mulch film is recycled by the recycling system, avoiding the time-consuming and labor-intensive process of manual soil covering.

[0013] As can be seen from the above technical solution, the advantages of this utility model are as follows: With the second support plate and connecting rods, multiple auxiliary rollers are arranged in parallel during mulch film recycling to complete the mulch film winding and recycling. When removing the mulch film, the worker pulls the second support plate, thereby moving several connecting rods, which in turn move several auxiliary rollers closer to the second support plate, resulting in a state where one end of the recycling unit has a larger diameter and the other end has a smaller diameter. At this point, the worker can easily move the mulch film to the vicinity of the second support plate for removal, without needing to climb onto the machine or use auxiliary tools. The locking unit ensures that the recycling system does not require adjustment of the auxiliary rollers during operation, guaranteeing the stability of the mulch film recycling. The locking element and the first locking hole allow the worker to easily adjust the locking element by hand. The second locking hole allows the worker to place the locking element inside during the mulch film removal process, thus achieving stability during mulch film removal. By setting up two symmetrical soil-turning rollers, the mulch film is turned out of the soil before being recycled on the recycling unit, avoiding excessive breakage of the mulch film due to soil covering, which could affect subsequent planting. The soil-covering component ensures that the soil is promptly returned to its original position after the mulch film is recycled, avoiding the time-consuming and labor-intensive manual soil covering.

[0020] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0021] Example:

[0022] like Figures 1-3 As shown, an integrated machine for uncovering, ridging, and fertilizing includes a main frame 1. A soil-turning unit is located at the front end of the main frame 1, and a soil-covering unit is located behind the soil-turning unit. A recovery unit is also located on the main frame 1. The recovery unit includes a rotatable main roller 2 mounted on the main frame 1 and a speed-regulating motor 12. The main roller 2 is driven to rotate by the speed-regulating motor 12. A first support plate 3 is located at one end of the main roller 2, and several auxiliary rollers 4 are hinged to the first support plate 3. A second support plate 5 is slidably mounted at the other end of the main roller 2. Connecting rods 6, the same number as the auxiliary rollers 4, are hinged to the second support plate 5. The other ends of the connecting rods 6 are hinged to the other ends of the auxiliary rollers 4 and are arranged in a one-to-one correspondence. A locking unit is fixedly connected to the second support plate 5, which can restrict the movement of the main roller 2 and the auxiliary rollers 4. The relative displacement between the two support plates 5 is configured such that, through the second support plate 5 and the connecting rods 6, multiple auxiliary rollers 4 are arranged in parallel during the mulch film recycling process to complete the mulch film winding and recycling. When removing the mulch film, the worker pulls the second support plate 5, thereby moving several connecting rods 6, which in turn moves several auxiliary rollers 4 closer to the second support plate 5, completing the state where one end of the recycling unit has a larger diameter and the other end has a smaller diameter. At this time, it is convenient for the worker to move the mulch film to the vicinity of the second support plate 5 for removal without the need for the worker to climb onto the machine or use auxiliary tools to remove the mulch film. The locking unit ensures that the recycling system does not adjust the auxiliary rollers 4 during operation, thus ensuring the stability of the mulch film recycling.

[0023] In this embodiment, the locking unit includes a sliding member 7 and a locking member 8. The sliding member 7 is fixedly connected to the second support plate 5 and has a through hole. The main roller 2 has a first locking hole. One end of the locking member 8 can move through the through hole into the first locking hole. When the locking member 8 is in the first locking hole, several auxiliary rollers 4 are in a parallel state. The main roller also has a second locking hole. One end of the locking member 8 can move through the through hole into the second locking hole. When the locking member 8 is in the second locking hole, several auxiliary rollers 4 are in a non-parallel state. With this configuration, the locking member 8 and the first locking hole make it easy for workers to adjust the locking member 8 by hand. With the second locking hole, when removing the mulch film, workers can place the locking member 8 in the second locking hole, thereby achieving stability when removing the mulch film.

[0024] In this embodiment, the soil turning unit includes two soil turning rollers 9 symmetrically arranged on the main frame 1. The lower end of the soil turning roller 9 is located below the mulch film in the soil during operation to turn the mulch film out. With this arrangement, by setting two symmetrical soil turning rollers 9, the mulch film is turned out of the soil before the mulch film is recycled in the recycling unit, avoiding excessive breakage of the mulch film caused by soil covering, which would affect subsequent planting.

[0025] In this embodiment, the soil covering unit includes two soil covering components symmetrically arranged on the main frame 1. The soil covering components are rotatably arranged on the main frame 1. The main frame 1 is also provided with a reversing gear box 13. Under the action of an external power source, the reversing gear box 13 transmits power to the soil covering components through sprockets and chains. The soil covering components include a rotating shaft 10 and several soil covering plates 11. With this arrangement, the soil covering components can promptly cover the soil back to its original position after the mulch film is recycled by the recycling system, avoiding the time-consuming and laborious process of manual soil covering.

[0026] In this embodiment, a film-cutting blade 14 is also installed at the front of the main frame 1. The film-cutting blade 14 can be adjusted in the width direction of the main frame 1. When working, the film-cutting blade 14 does not have relative displacement with the main frame 1 in the width direction. When working, the film-cutting blade abuts against the unlifted mulch film, causing the mulch film to break into two parts when lifted. This setting can prevent the planted crops from being pulled up together when the mulch film is lifted too quickly. At the same time, the position-adjustable film-cutting blade 14 can be adjusted synchronously according to the offset of the crop position during planting and mulching.

[0027] In this embodiment, a fertilizer box 15 is also provided on the main frame 1. A fertilizer pipe 16 is connected to the bottom of the fertilizer box 15. The lower end of the fertilizer pipe 16 can release fertilizer into the soil after the exfoliation work and before the covering work, thus avoiding the time-consuming and labor-intensive problem caused by using manual fertilizer application.

[0028] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
