Description

Technical Field

[0001] This utility model relates to the field of mechanized inter-row cultivation technology, and more specifically to a contour-following self-rolling tobacco field film-removing inter-row cultivation machine. Background Technology

[0002] During the seedling stage of tobacco fields, two important tasks are removing the plastic film and cultivating the soil around the base. While mechanized cultivation techniques are relatively mature, removing the plastic film is still mostly done manually, and mature mechanical film-removing equipment is not yet available on the market. Traditional tobacco field plastic film is usually thin and has low strength, making it prone to breakage during removal. Furthermore, when tobacco seedlings are in the seedling stage, their above-ground height can reach 60cm, and the natural diameter of their leaves is approximately 50cm. The soil above the film and the seedlings themselves easily cause the film to break during removal. These factors severely restrict the development of mechanized film removal.

[0003] Manually removing the plastic film requires a large workforce, with each step—removing, collecting, and transporting—requiring specialized personnel. Without disrupting the planting season, at least 15 people are needed to clean 70 mu (approximately 4 hectares) of tobacco fields. The removed film is left in the middle of the ridges, requiring specialized personnel to collect and gather it at the edge of the field before loading it onto trucks and transporting it out. This process is labor-intensive and inefficient. With the increasing outflow of rural population each year, tobacco farmers face significant difficulties in recruiting workers, making the mechanization of film removal particularly urgent.

[0004] Regarding existing tobacco field film removal machinery, while foreign tobacco planting has a high degree of mechanization, its technology and management models are not entirely suitable for my country's national conditions. Domestic research specifically on tobacco field film removal equipment is limited and has many shortcomings. For example, some hand-held film removal machines have simple structures, but require manual winding of the film onto a mandrel before a motor drives the mandrel to continuously wind the film into rolls. If the film breaks, it must be manually rewound, and once rolled to a certain size, it must be manually unloaded, the mandrel replaced, and the operation continued. This reliance on manual labor is too high, resulting in low overall efficiency. Furthermore, film removal and earthing up must be done in two separate steps, failing to achieve the goal of reducing the number of times the machine needs to be used in the field. Some towed film-removing machines are towed by a tractor unit. While this solves the problem of excessive soil accumulation on the film causing it to break to some extent, the recovery of the film that is cut and pressed under the soil is not very effective. Film wrapping still needs to be done manually. The film limiting mechanism does not fully consider the differences in the growth of tobacco seedlings and is prone to damaging taller seedlings. It also has the problem that film removal and cultivation need to be done in two separate steps. Overall, there is still a lot of room for improvement.

[0005] In summary, there are few existing tobacco field film removal machines in China, and they are not fully automated. Manual film wrapping and mandrel replacement are required, resulting in poor operational reliability, limited machine functions, low integration, and low work efficiency. Furthermore, they are prone to damaging tobacco seedlings during operation.

[0006] Therefore, it is of great significance to develop a contour-following self-rolling tobacco field film removal and inter-cultivation integrated operation machine to realize automated film removal and integrated film removal and inter-cultivation, reduce labor, improve work efficiency, and reduce work intensity. Utility Model Content

[0007] In view of this, the present invention provides a contour-following self-rolling tobacco field film removal and inter-cultivation integrated machine, which aims to solve the above-mentioned technical problems.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A contour-following self-rolling tobacco field film-removing and inter-cultivation integrated machine includes:

[0010] The frame has a front end for connecting to a walking power mechanism, a seedling support device at the middle of the front end of the frame for gathering and pressing down the tobacco seedling leaves during the film removal process, and ground wheels rotatably connected to both sides of the front end of the frame.

[0011] The plastic film shovel is provided in two symmetrical arrangements on both sides of the rear of the seedling support device. The plastic film shovel is inclined from the top of the rear end of the frame to the bottom of the front end of the frame, so that after the plastic film is lifted by the plastic film shovel, it moves backward and upward along the curved surface of the plastic film shovel.

[0012] A coreless self-winding mechanism for mulch film is located at the top rear end of the frame and is used to collect and wind the mulch film conveyed by the mulch film shovel.

[0013] Through the above technical solution, this utility model automates the film-unwrapping process by incorporating a seedling support device, a film shovel, and a coreless self-rolling mechanism. This not only greatly improves operational efficiency but also significantly reduces labor requirements and effectively lowers labor intensity. Regarding seedling protection, the seedling support device cleverly gathers and lowers the seedling leaves, minimizing damage to the seedlings during film removal. Simultaneously, this mechanism improves the quality of film recycling, making the recycled film easier for subsequent processing or reuse.

[0014] Preferably, in the above-mentioned contour-following self-winding tobacco field film-unwinding and tillage integrated machine, a guide frame is provided between the top of the film shovel and the coreless self-winding mechanism. The film conveyed by the film shovel is guided into the coreless self-winding mechanism by the guide frame. The guide frame ensures that the film can enter the coreless self-winding mechanism stably and accurately. This not only improves the stability and success rate of film winding but also effectively reduces film deviation and jamming during the conveying process. In actual operation, this design ensures smooth film recovery, avoids operation interruptions caused by poor film conveying, and thus improves the continuity and efficiency of the overall operation.

[0015] Preferably, in the above-mentioned contour-following self-winding tobacco field film-unwinding and tillage integrated machine, an electric push rod is installed at the top of the guide frame, with the telescopic rod of the electric push rod facing the film wound on the coreless self-winding mechanism. The electric push rod facilitates precise control of the film winding state. The tightness and pressure of the film winding can be flexibly adjusted as needed, thereby improving the quality of the film winding. Simultaneously, this greatly facilitates the subsequent film unloading operation, making the unloading process smoother and more efficient.

[0016] Preferably, in the aforementioned contour-following self-rolling tobacco field film-unwinding and tillage integrated machine, a monitoring system is installed on the electric push rod. This monitoring system monitors the film-rolling status and triggers an alarm when the film is rolled to a set size. The monitoring system enables real-time monitoring of the film-rolling process. Operators can promptly and accurately grasp the film-rolling status, ensuring timely alarm reminders when the film is rolled to the appropriate size. This design not only improves the automation and reliability of the operation but also effectively reduces errors and labor intensity associated with manual monitoring, making the entire film-rolling process more intelligent and precise.

[0017] Preferably, in the above-mentioned contour-following self-rolling tobacco field film-unwrapping and tillage integrated machine, multiple conveying rollers are rotatably connected to the frame. These conveying rollers are arranged above the film-wrapping shovel along its conveying direction and cooperate with the shovel to convey the film. The multiple conveying rollers enhance the stability and smoothness of film conveying. The perfect cooperation between the conveying rollers and the film-wrapping shovel effectively prevents problems such as slippage, wrinkling, or breakage of the film during conveying. In practical applications, this design significantly improves the continuity and efficiency of film-unwrapping operations, providing a strong guarantee for high-quality film recycling.

[0018] Preferably, in the above-mentioned contour-following self-rolling tobacco field film-unwrapping and tillage integrated machine, the ends of multiple conveyor rollers are sequentially connected by a conveyor chain to achieve sequential power transmission. The uppermost conveyor roller is driven to rotate by a drive motor fixed on the frame, and the power output end of the drive motor is connected to the uppermost conveyor roller via the conveyor chain. The conveyor chain connects the conveyor rollers and realizes power transmission, enabling the entire conveying system to work efficiently and collaboratively. This not only improves the efficiency and reliability of power transmission but also ensures the stability of film conveying. During operation, this stable power transmission mechanism can effectively avoid abnormal film conveying caused by insufficient or unstable power, thereby improving the stability and success rate of the operation.

[0019] Preferably, in the aforementioned contour-following self-rolling tobacco field film-unwrapping and inter-cultivation integrated machine, the seedling support device consists of two side plates and an arc-shaped plate fixed between the upper parts of the two side plates. The distance between the upper parts of the two side plates gradually increases from bottom to top, and the convex surface of the arc-shaped plate faces the walking power mechanism. The seedling support device has a unique and ingenious structural design, which can effectively gather and press down the tobacco seedling leaves. This not only reduces damage to the tobacco seedlings during film removal but also significantly reduces the obstruction of film removal operations by the tobacco seedlings. In actual operation, this design effectively improves the efficiency and quality of film removal, laying a good foundation for subsequent film recycling and inter-cultivation and hilling operations.

[0020] Preferably, in the above-mentioned contour-following self-winding tobacco field film-unwinding and tillage integrated machine, the coreless self-winding mechanism of the mulch film includes two film-winding rollers rotatably connected in parallel to the frame. The height of the rear film-winding roller is higher than that of the front film-winding roller, so that the two film-winding rollers are staggered. Driven by the film-winding motor, they rotate, providing centripetal force to the mulch film, causing it to self-wind. The staggered arrangement of the film-winding rollers in the coreless self-winding mechanism provides a more stable film-winding effect. This structure eliminates the need for a mandrel to roll up residual film and manual replacement of the mandrel, reducing labor and automating the film unwinding process.

[0021] Preferably, in the aforementioned contour-following self-rolling tobacco field film-unwrapping and inter-cultivation integrated machine, a fertilizer box is fixed to the top front end of the frame, and fertilizer delivery pipes extending downwards to both sides of the bottom of the fertilizer box to the sides of the tobacco ridges. The fertilizer box and fertilizer delivery pipes enable precise fertilization during film unwrapping and inter-cultivation operations. This not only integrates multiple operations but also significantly improves work efficiency. By reducing the number of times the equipment enters the field, it effectively reduces soil compaction and damage, which is beneficial for soil structure protection and tobacco growth. Simultaneously, precise fertilization improves fertilizer utilization, reduces fertilizer waste, lowers production costs, and increases economic benefits.

[0022] Preferably, in the aforementioned contour-following self-rolling tobacco field film-removing and inter-cultivation integrated machine, the rear ends of the frame are equipped with cultivation and hilling shovels located on both sides of the tobacco ridges. The cross-section of the cultivation and hilling shovels is V-shaped, with the V-shaped tip pointing forward. This scientifically designed cultivation and hilling shovel effectively removes weeds from the ridges and precisely hills the soil to the roots of the tobacco seedlings. This not only promotes the growth of tobacco roots and enhances the lodging resistance of the seedlings, but also improves the management quality of the tobacco field and the yield of tobacco. In actual operation, this design is coordinated with film removal, fertilization, and other operations, further improving the overall performance and operational efficiency of the equipment, providing tobacco farmers with a more comprehensive and efficient mechanized solution.

[0023] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a contour-following self-rolling tobacco field film-unwrapping and inter-cultivation integrated machine, which has the following beneficial effects:

[0024] 1. High degree of automation: Through its unique structural design, this equipment can automate and integrate multiple operations such as film removal, inter-row cultivation, and fertilization. This not only significantly improves operational efficiency but also greatly reduces reliance on manual labor, lowers labor intensity, and provides tobacco farmers with a more relaxed and efficient way of working.

[0025] 2. Protecting tobacco seedlings: The specially designed seedling support effectively gathers and presses down the tobacco seedling leaves, reducing damage to the seedlings during the film removal process and ensuring healthy growth. This is of great significance for improving tobacco yield and quality.

[0026] 3. Improve the quality of plastic film recycling: The equipment's film-unwrapping and conveying device and the coreless self-winding mechanism work together seamlessly to stably and accurately recycle the plastic film and wind it into shape, facilitating subsequent processing or reuse, while reducing white pollution in the fields.

[0027] 4. Intelligent monitoring: The equipped monitoring system can monitor the status of the film roll in real time, and provide timely alarm reminders to ensure the smooth progress of the operation and reduce the error and labor intensity of manual monitoring.

[0028] 5. High operational efficiency: The integrated design of multiple operations reduces the number of times machinery needs to enter the field, minimizes soil compaction damage, and improves equipment utilization. This not only protects the soil structure but also benefits tobacco growth, thereby increasing overall production efficiency.

[0029] 6. High adaptability: The equipment can adapt to different field conditions and tobacco seedling growth status, and has strong versatility and flexibility, which can meet the management needs of different tobacco fields.

[0030] 7. Significant economic benefits: By improving operational efficiency, reducing labor costs, lowering equipment wear and tear, and increasing fertilizer utilization, production costs have been significantly reduced, economic benefits have been improved, and tangible benefits have been brought to tobacco farmers.

[0051] 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.

[0052] See appendix Figure 1 and attached Figure 5 This utility model discloses a contour-following self-rolling tobacco field film-removing and inter-cultivation integrated machine, comprising:

[0053] The frame 1 has a front end for connecting to the walking power mechanism. The front middle of the frame 1 is equipped with a seedling support 4, which is used to gather and press down the tobacco seedling leaves during the film removal process. The front sides of the frame 1 are rotatably connected with ground wheels 11.

[0054] There are two mulch shovels 2, which are symmetrically arranged on both sides of the rear of the seedling support device 4. The mulch shovels 2 are arranged at an angle from the top of the rear end of the frame 1 to the bottom of the front end of the frame 1, so that after the mulch 8 is lifted by the mulch shovels 2, it moves backward and upward along the curved surface of the mulch shovels 2.

[0055] The coreless self-winding mechanism 3 is located at the top rear end of the frame 1 and is used to collect and wind up the mulch film 8 delivered by the mulch film shovel 2.

[0056] To further optimize the above technical solution, a guide frame 12 is provided between the top of the mulch shovel 2 and the coreless self-winding mechanism 3. The mulch 8 conveyed by the mulch shovel 2 is guided into the coreless self-winding mechanism 3 through the guide frame 12.

[0057] To further optimize the above technical solution, an electric push rod 5 is installed on the top of the guide frame 12, and the telescopic rod of the electric push rod 5 is directed toward the mulch film 8 wound on the coreless self-winding mechanism 3.

[0058] To further optimize the above technical solution, a monitoring system is installed on the electric push rod 5. The monitoring system is used to monitor the rolling status of the film and trigger an alarm when the film 8 is rolled to the set size.

[0059] See appendix Figure 3 Multiple conveying rollers 13 are rotatably connected to the frame 1. The multiple conveying rollers 13 are arranged above the mulch shovel 2 along the conveying direction of the mulch shovel 2 and cooperate with the mulch shovel 2 to convey the mulch film 8.

[0060] To further optimize the above technical solution, the ends of multiple conveyor rollers 13 are connected in sequence by a conveyor chain 14 to achieve sequential power transmission. The uppermost conveyor roller 13 is driven to rotate by a drive motor 15 fixed on the frame 1. The power output end of the drive motor 15 is connected to the uppermost conveyor roller 13 by the conveyor chain 14.

[0061] See appendix Figure 2 The seedling support device 4 consists of two side plates 41 and an arc plate 42 fixed between the upper parts of the two side plates 41. The distance between the upper parts of the two side plates 41 gradually increases from bottom to top, and the convex surface of the arc plate 42 faces the walking power mechanism.

[0062] The seedling support device 4 has an arc-shaped plate 42 in the middle that is higher in the front and lower in the back. This plate can gather the tobacco seedling leaves and press them down to a certain height, allowing as much of the mulch film as possible to be exposed without damaging the seedlings, thus reducing the probability of the mulch film breaking.

[0063] During the film removal period, the tobacco seedlings are about 60cm tall above ground, and the natural diameter of the leaves is about 50cm. Due to the large size of the tobacco plants, the resistance to film removal is increased, easily leading to film breakage and posing a significant challenge to mechanized film removal. Therefore, seedling support technology has been developed, such as... Figure 2 As shown, the seedling support device 2 gathers the large tobacco leaves together and lowers the tobacco plant to a certain height. The seedling support device 2 protects the tobacco leaves and reduces the resistance when removing the film, effectively solving the problem of film breakage.

[0064] See appendix Figure 4 The coreless self-winding mechanism 3 for mulch film includes two film-winding rollers 31 that are rotatably connected in parallel on the frame 1. The height of the rear film-winding roller 31 is higher than that of the front film-winding roller 31, so that the two film-winding rollers 31 are staggered and rotate under the drive of the film-winding motor, providing centripetal force to the mulch film 8 so that the mulch film 8 self-winds.

[0065] In this embodiment, the two film-rolling rollers 31 rotate clockwise. The coreless self-winding mechanism 3 is the core for realizing automated film removal and reducing labor. By designing staggered smooth rollers, which rotate clockwise under the drive of a motor, the film is driven to self-wind under the action of instantaneous centripetal force and gravity.

[0066] In this embodiment, the shovel 2 has a structure that is higher on the inside and lower on the outside, and lower at the front and higher at the rear. Pulled by a tractor, it shovels up the plastic film 8, and the soil covering the film 8 slides down to both sides of the tobacco ridge 9. The film 8 moves upward and backward along the curved surface of the shovel 2. To prevent the film from sliding down, three rubber conveyor rollers 13 are provided, continuously propelling the film 8 upward and backward until it is guided by the guide frame 12 onto two film-winding rollers 31. The two film-winding rollers 31 are staggered and rotate under the drive of the film-winding motor, providing centripetal force to the film 8 so that it self-winds. Once the film 8 has rolled to a certain size, the driver can choose the unloading time to unload the film roll.

[0067] The shovel 2 is connected to the frame 1. Its height can be adjusted according to the ground conditions. The inclination angle of the shovel 2 should not be too large or too small; too large an angle will cause the plastic film 8 to accumulate on the ground surface, while too small an angle will lengthen the shovel 2, making it difficult to ensure the smooth upward conveyance of the plastic film 8. Three conveyor rollers 13 are installed above the shovel 2. A chain mechanism drives the conveyor rollers 13 to rotate counterclockwise, moving the plastic film 8 smoothly upward and backward. The tail of the shovel 2 features a guide plate with gradually narrowing width, connected to the frame 1, which limits the width of the plastic film for subsequent roll forming.

[0068] To further optimize the above technical solution, a fertilizer box 6 is fixed at the top front end of the frame 1, and fertilizer conveying pipes 61 extending downward to both sides of the bottom of the fertilizer box 6.

[0069] To further optimize the above technical solution, the rear end of the frame 1 is provided with two cultivation and hilling shovels 7 located on both sides of the tobacco ridge. The cross-section of the cultivation and hilling shovels 7 is V-shaped, and the tip of the V-shape faces forward.

[0070] Fertilizer is applied to both sides of the tobacco roots after the film is removed via a fertilizer applicator and delivery pipe. Weeds are removed in the furrows by the cultivation shovel 7, and the soil in the furrows is then piled up to the roots of the tobacco seedlings to promote the growth of the tobacco root system.

[0071] When the equipment is operating in the field:

[0072] The seedling support device 4 plays an important role. It consists of two side plates 41 and an arc-shaped plate 42. The arc-shaped plate 42 faces the tractor and forms a "V"-shaped structure, which can gather the tobacco seedling leaves on both sides inward and press them down appropriately to avoid damaging the tobacco seedlings during the film removal process, while also reducing the obstruction of the tobacco seedlings to subsequent film removal operations.

[0073] Two plastic film shovels 2 are symmetrically arranged on both sides behind the seedling support device 4 and installed at an angle. Under the tractor's pull, the plastic film shovels 2 scoop up the plastic film 8, and the plastic film 8 moves backward and upward along the curved surface of the plastic film shovels 2.

[0074] Multiple conveyor rollers 13 are installed above the shovel 2 and are connected in sequence by a conveyor chain 14. The uppermost conveyor roller 13 is driven by a drive motor 15. The conveyor rollers 13 are arranged in the conveying direction of the shovel 2 and cooperate with the shovel 2 to smoothly convey the mulch film 8 backward.

[0075] The plastic film 8 is guided by the guide frame 12 and enters the coreless self-winding mechanism 3. This mechanism includes two staggered film-winding rollers 31, which are driven by a film-winding motor to rotate clockwise, providing centripetal force to the plastic film 8 so that it can be automatically wound into shape in a coreless state.

[0076] The top of the guide frame 12 is equipped with an electric push rod 5, which features a monitoring system that monitors the size of the plastic film roll in real time. When the plastic film roll 8 reaches the set size, the monitoring system triggers an alarm to alert the operator. The electric push rod 5 then activates, extending the plastic film roll and completing the unloading process.

[0077] The top front end of the frame 1 is equipped with a fertilizer box 6, and fertilizer delivery pipes 61 are connected to both sides of its bottom, extending to both sides of the tobacco ridge 9. The fertilizer is delivered to both sides of the tobacco roots after the film is removed via the fertilizer dispenser and delivery pipes.

[0078] The tillage and hilling shovels 7 are located on both sides of the rear end of the frame 1, in a V-shape with the pointed end facing forward. During operation, the tillage and hilling shovels 7 remove weeds while simultaneously hilling the soil in the furrows up to the roots of the tobacco seedlings, promoting the growth of the tobacco root system.

[0079] This machine features a compact structure, simple operation, high reliability, and a high degree of automation. It adopts a combined operation mode of tractor traction, which improves production efficiency, reduces labor costs and labor intensity for tobacco farmers, and reduces the number of times the tractor needs to be driven into the field, effectively reducing the compaction and damage to the land caused by the tractor, thus providing technical support for achieving the "double reduction" (reduction of labor costs and labor intensity).

[0080] In other embodiments, the contour-following self-rolling tobacco field film-unwrapping and inter-cultivation integrated machine can be designed with a detachable structure. For example, the seedling support device 4, the film shovel 2, the coreless self-rolling film mechanism 3, the fertilizer box 6, and the inter-cultivation and hilling shovel 7 can all be designed to be detachably connected to the frame 1, and the disassembly method can be achieved by bolt connection. This detachable and assembleable structure can adapt to the needs of farming at different stages and improve the utilization rate of the equipment.

[0081] When a film removal operation is required, the overall structure remains the same as described in the above embodiments.

[0082] When the film removal is completed and the soil is cultivated and hilled, the seedling support device 4, the film shovel 2 and other structures related to the film removal operation can be removed, and the soil can be hilled multiple times using the cultivation and hilling shovel 7.

[0083] This structural design overcomes the shortcomings of traditional structures, such as limited functionality and low operational flexibility, resulting in higher equipment utilization.

[0084] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

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.
