Description

Technical Field

[0001] The invention relates to the technical field of mechanized intertillage cultivation, and more particularly to a contoured self-rolling tobacco field film-removing and intertillage cultivation integrated operation machine. Background Art

[0002] During the clustering stage of tobacco seedlings, tobacco field management requires two key operations: film removal and intertillage cultivation. While mechanized intertillage cultivation technology is relatively mature, film removal is still mostly done manually, and mature mechanical film removal equipment is not yet commercially available. Traditional tobacco field mulch films are typically thin and weak, making them prone to breakage during the removal process. During the clustering stage, the above-ground height of tobacco seedlings can reach 60 cm, and the diameter of their naturally extended leaves is approximately 50 cm. The soil above the film and the tobacco seedlings themselves can easily cause it to break during removal, severely hindering the development of mechanized film removal.

[0003] Manual film removal requires a significant amount of labor, requiring dedicated personnel to perform all steps, including film removal, collection, and transportation. At least 15 people are needed to clean a 70-mu tobacco field without disrupting the farming season. The removed film is left scattered in the middle of the ridges, requiring specialized personnel to gather it at the edge of the field before loading it onto trucks for transport. This is labor-intensive and inefficient.

[0004] Regarding existing tobacco film-removing machinery, while tobacco cultivation abroad is highly mechanized, its technology and management models do not fully align with my country's conditions. Domestic research specifically focused on tobacco film-removing equipment is limited and presents numerous shortcomings. For example, some hand-held film-removing machines have a simple structure, but the film must be manually wound around a core shaft. A motor then drives the core shaft to continuously wind the film into a roll. If the film breaks, it must be manually rewound. Once the film reaches a certain size, it must be manually removed and the core shaft replaced before continuing operation. This high reliance on manpower leads to low overall efficiency. Furthermore, film removal and tillage and soiling must be performed separately, failing to achieve the goal of reducing the number of machine applications. There are also some traction-type film strippers, which use a tractor to pull the film stripper to move. Although this has solved the problem of the film being pulled apart due to excessive soil accumulation on the film to a certain extent, the recovery effect of the film pressed under the soil after being cut is not good, and the film winding still needs to be done manually. The film limiting mechanism does not fully consider the growth differences of tobacco seedlings and is likely to damage taller tobacco seedlings. There is also the problem that film stripping and inter-cultivation and soiling need to be carried out in two steps. Overall, there is still a lot of room for improvement.

[0005] In summary, there are few existing tobacco field film-removing machines in China, and they are not fully automated. Manual film wrapping and core shaft replacement are required. The operation reliability is poor, the machine functions are single, the degree of integrated operation is low, the work efficiency needs to be improved, and the tobacco seedlings are easily damaged during the operation.

[0006] Therefore, it is of great significance to develop a contoured self-rolling tobacco field film-removing and tillage-integrated operation machine to realize the automation of film removal and the integration of film removal and tillage, reduce labor, improve work efficiency, and reduce work intensity. Summary of the Invention

[0007] In view of this, the present invention provides a contoured self-rolling tobacco field film-removing and tillage-integrated operation machine, aiming to solve the above-mentioned technical problems.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] A contoured self-rolling tobacco field film-removing and tillage-integrated machine, comprising:

[0010] The frame, the front end of the frame is used to connect the walking power mechanism, the middle part of the front end of the frame is provided with a seedling supporter, the seedling supporter is used to retract and press down the tobacco seedling leaves during the film peeling process, and the front ends of the frame are rotatably connected to ground wheels;

[0011] There are two mulch shovels, which are symmetrically arranged on both sides of the rear of the seedling supporter. The mulch shovels are arranged obliquely from the rear end top of the frame to the front end bottom of the frame, so that after the mulch is scooped up by the mulch shovel, it moves backward and upward along the curved surface of the mulch shovel;

[0012] A ground film coreless self-winding mechanism is provided at the top rear end of the frame and is used for recovering and winding the ground film delivered by the ground film shovel.

[0013] Through the above-mentioned technical solution, the present invention automates the film removal process by providing a seedling supporter, a film shovel, and a coreless film self-winding mechanism. This not only greatly improves operational efficiency but also significantly reduces labor requirements, effectively lowering labor intensity. To protect tobacco seedlings, the seedling supporter cleverly gathers and presses down the leaves of the seedlings, minimizing damage to the seedlings during film removal. Furthermore, this mechanism improves the quality of film recovery, making the recovered film easier to process or reuse.

[0014] Preferably, in the above-mentioned contoured self-rolling tobacco field film-removing and tillage-integrated operation machine, a guide frame is provided between the top of the film shovel and the film coreless self-rolling mechanism, and the film transported by the film shovel is guided into the film coreless self-rolling mechanism via the guide frame. The provision of the guide frame ensures that the film can stably and accurately enter the film coreless self-rolling mechanism. This not only improves the stability and success rate of the film roll, but also effectively reduces the deviation and jamming of the film during the transportation process. In actual operation, this design can ensure the smooth recovery of the film, avoid operation interruptions caused by poor film transportation, and thus improve the continuity and efficiency of the overall operation.

[0015] Preferably, in the aforementioned contoured, self-winding tobacco field film stripping and cultivation machine, an electric push rod is mounted on the top of the guide frame, with its telescopic rod directed toward the film wound on the coreless self-winding mechanism. The placement of the electric push rod facilitates precise control of the film's winding state. The film's tightness and pressure can be flexibly adjusted as needed, thereby improving film quality. This also greatly facilitates subsequent film removal, making the process smoother and more efficient.

[0016] Preferably, in the aforementioned contoured, self-rolling tobacco film-removing and tillage-integrated machine, a monitoring system is installed on the electric push rod. This system monitors the film rolling status and triggers an alarm when the film is rolled to a set size. This monitoring system enables real-time monitoring of the film rolling process. Operators can promptly and accurately monitor the film rolling status, ensuring that an alarm is triggered 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 the errors and labor intensity of manual monitoring, making the entire film rolling process more intelligent and precise.

[0017] Preferably, in the above-mentioned contoured self-rolling tobacco field film-removing and tillage-integrated operation machine, a plurality of conveying rollers are rotatably connected to the frame, and the plurality of conveying rollers are arranged above the film shovel along the conveying direction of the film shovel, and cooperate with the film shovel to convey the film. The setting of multiple conveying rollers enhances the stability and smoothness of film transportation. The perfect coordination between the conveying rollers and the film shovel can effectively prevent the film from slipping, wrinkling or breaking during transportation. In actual application, this design significantly improves the continuity and efficiency of the film-removing operation, providing a strong guarantee for high-quality film recovery.

[0018] Preferably, in the above-mentioned contoured self-rolling tobacco field film-removing and tillage-integrated operation machine, the ends of the multiple conveying rollers are connected in sequence through a conveying chain, and the power is transmitted in sequence. The top conveying roller is driven to rotate by a drive motor fixed to the frame, and the power output end of the drive motor is connected to the top conveying roller through the conveying chain. The conveying chain connects the conveying rollers and realizes power transmission, so that the entire conveying system can work efficiently and collaboratively. This not only improves the efficiency and reliability of power transmission, but also ensures the smoothness of film transportation. During the operation process, this stable power transmission mechanism can effectively avoid abnormal film transportation caused by insufficient or unstable power, thereby improving the stability and success rate of the operation.

[0019] Preferably, in the above-mentioned contoured self-rolling tobacco field film-removing and inter-cultivation integrated operation machine, the seedling supporter is composed of two side panels and an arc-shaped plate fixed between the upper parts of the two side panels. The distance between the upper parts of the two side panels gradually increases from bottom to top, and the convex surface of the arc-shaped plate faces the walking power mechanism. The structural design of the seedling supporter is unique and ingenious, and can effectively gather and press down the leaves of the tobacco seedlings. This not only reduces the damage to the tobacco seedlings during the film removal process, but also significantly reduces the obstruction of the tobacco seedlings to the film removal operation. In actual operation, this design effectively improves the efficiency and quality of film removal, and lays a good foundation for subsequent film recovery and inter-cultivation and soiling operations.

[0020] Preferably, in the aforementioned contoured self-rolling tobacco film stripping and tillage machine, the coreless film self-winding mechanism includes two film rolling rollers that rotate in parallel on the frame, with the rear film rolling roller being higher than the front film rolling roller. This allows the two film rolling rollers to be staggered and rotated by a film rolling motor, providing centripetal force to the film, causing it to self-roll. The staggered arrangement of the film rolling rollers in the coreless film self-winding mechanism provides a more stable film rolling effect. This structure eliminates the need for a mandrel to roll up residual film and eliminates the need for manual mandrel replacement, reducing labor and achieving automated film stripping.

[0021] Preferably, in the above-mentioned contoured self-rolling tobacco field film-removing and tillage-integrated operation machine, a fertilizer box is fixed to the front top of the frame, and the bottom two sides of the fertilizer box are provided with fertilizer delivery pipes extending downward to both sides of the tobacco ridge. The arrangement of the fertilizer box and the fertilizer delivery pipe enables the equipment to carry out precise fertilization while performing film-removing and tillage operations. This not only realizes the integration of multiple operations, but also greatly improves work efficiency. By reducing the number of times the equipment enters the field, the compaction damage to the soil is effectively reduced, which is beneficial to the protection of the soil structure and the growth of tobacco. At the same time, the precise fertilization method can improve the utilization rate of fertilizers, reduce fertilizer waste, reduce production costs, and improve economic benefits.

[0022] Preferably, in the above-mentioned contoured self-rolling tobacco field film-removing and tillage-integrated operation machine, the rear ends of the frame are provided with tillage shovels located on both sides of the tobacco ridge, and the cross-section of the tillage shovel is V-shaped, with the V-shaped tip facing forward. The design of the tillage shovel is scientific and reasonable, which can effectively remove weeds in the ridges and ditches and accurately cultivate the soil to the roots of the tobacco seedlings. This not only promotes the growth of the tobacco root system and enhances the lodging resistance of the tobacco seedlings, but also improves the management quality of the tobacco field and the tobacco yield. In actual operation, this design is coordinated with operations such as film removal and fertilization to further improve the comprehensive performance and operation efficiency of the equipment, providing tobacco farmers with a more comprehensive and efficient mechanization solution.

[0023] Through the above technical solutions, it can be seen that compared with the prior art, the present invention provides a contoured self-rolling tobacco field film-removing and tillage-integrated operation machine, which has the following beneficial effects:

[0024] 1. High degree of automation: Through its unique structural design, the equipment can automate and integrate multiple operations such as film removal, tillage, and fertilization. This not only significantly improves operational efficiency, but also greatly reduces reliance on manpower and labor intensity, providing tobacco farmers with a more relaxed and efficient operation method.

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

[0026] 3. Improve the quality of mulch film recovery: The equipment's film-removing and conveying device and the mulch film coreless self-winding mechanism work in perfect harmony, which can stably and accurately recover the mulch film and roll it into shape for subsequent processing or secondary utilization, while reducing white pollution in the field.

[0027] 4. Intelligent monitoring: The equipped monitoring system can monitor the status of the film roll in real time and issue alarms in time to ensure the smooth progress of the operation process, reducing the errors and labor intensity of manual monitoring.

[0028] 5. High operating efficiency: The integrated design of multiple operations reduces the number of times machinery enters the field, reduces soil compaction damage, and improves equipment utilization. This not only protects the soil structure, but also promotes tobacco growth and improves overall production efficiency.

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

[0030] 7. Significant economic benefits: By improving operational efficiency, reducing labor costs, lowering equipment losses, 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 following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] See attached Figure 1and attached Figure 5 The embodiment of the present invention discloses a contoured self-rolling tobacco field film-removing and tillage-integrated operation machine, comprising:

[0053] Frame 1, the front end of the frame 1 is used to connect the walking power mechanism, the front middle part of the frame 1 is provided with a seedling support 4, the seedling support 4 is used to collect and press down the tobacco seedling leaves during the film removal process, and the front ends of the frame 1 are rotatably connected to ground wheels 11 on both sides;

[0054] There are two mulch shovels 2, which are symmetrically arranged on both sides of the rear of the seedling supporter 4. The mulch shovels 2 are arranged obliquely 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 scooped up by the mulch shovel 2, it moves backward and upward along the curved surface of the mulch shovel 2;

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

[0056] In order to further optimize the above technical solution, a guide frame 12 is provided between the top of the mulch shovel 2 and the mulch coreless self-rolling mechanism 3 , and the mulch 8 transported by the mulch shovel 2 is guided into the mulch coreless self-rolling mechanism 3 through the guide frame 12 .

[0057] In order 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 ground film 8 wound on the ground film coreless self-winding mechanism 3.

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

[0059] See attached Figure 3 A plurality of conveying rollers 13 are rotatably connected to the frame 1 , and the plurality of 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 8 .

[0060] In order to further optimize the above technical solution, the ends of multiple conveying rollers 13 are connected in sequence through conveying chains 14 to realize the sequential transmission of power. The top conveying roller 13 is driven to rotate by a driving motor 15 fixed on the frame 1, and the power output end of the driving motor 15 is connected to the top conveying roller 13 through a conveying chain 14.

[0061] See attached Figure 2 The seedling supporting device 4 is composed of two side plates 41 and an arc-shaped plate 42 fixed between the upper portions of the two side plates 41. The spacing between the upper portions of the two side plates 41 gradually increases from bottom to top, and the convex surface of the arc-shaped plate 42 faces the walking power mechanism.

[0062] The middle of the seedling supporter 4 is an arc-shaped plate 42 with a high front and a low back, which can gather the tobacco seedling leaves and press them down to a certain height, so as to expose as much ground film as possible without damaging the tobacco seedlings, thereby reducing the probability of ground film breakage.

[0063] During the film-unwrapping period, the height of tobacco seedlings above the ground is about 60cm, and the diameter of the leaves that stretch naturally is about 50cm. When the film is unwrapped, the larger the tobacco plants are, the greater the resistance of the tobacco plants to the film, which can easily lead to film breakage and make mechanized film unwrapping very difficult. Figure 2 As shown, the seedling supporter 2 gathers the enlarged tobacco leaves and presses the tobacco plants down to a certain height. The seedling supporter 2 protects the tobacco leaves and reduces the resistance to film peeling, effectively solving the problem of film breakage.

[0064] See attached Figure 4 The coreless self-winding mechanism 3 of the ground film includes two film rolling rollers 31 connected to the frame 1 in parallel rotation, and the height of the film rolling roller 31 located at the rear is higher than the height of the film rolling roller 31 located at the front, so that the two film rolling rollers 31 are staggered and then rotated under the drive of the film rolling motor, providing centripetal force to the ground film 8 to make the ground film 8 self-roll.

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

[0066] In this embodiment, the mulch shovel 2 features a structure with a high interior and low exterior, and a low front and high rear. Pulled by a tractor, the mulch 8 is scooped up, and the soil covering it slides down the sides of the chimney 9. The mulch 8 moves upward and backward along the curved surface of the mulch shovel 2. To prevent it from sliding downward, three rubber conveyor rollers 13 are provided, continuously moving the mulch 8 upward and backward until it is guided by a guide frame 12 onto two film winding rollers 31. The two film winding rollers 31 are arranged in a staggered pattern and rotated by a film winding motor, providing centripetal force to the mulch 8, causing it to roll itself up. Once the mulch 8 has been rolled to a certain size, the operator can choose the appropriate time to unload the film.

[0067] The film shovel 2 is connected to the frame 1. The height of the shovel 2 can be adjusted according to the ground conditions. The inclination angle of the shovel 2 should be neither too large nor too small. A large inclination will cause the film 8 to accumulate on the surface, while a small inclination will extend the length of the shovel 2, making it difficult to ensure smooth upward conveyance of the 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 film 8 smoothly upward and backward. A guide plate with a gradually decreasing width is designed at the rear of the shovel 2 and connected to the frame 1 to limit the width of the film and facilitate subsequent roll formation.

[0068] In order to further optimize the above technical solution, a fertilizer box 6 is fixed to the top of the front end of the frame 1, and fertilizer conveying pipes 61 extending downward to both sides of the chimney 9 are provided on both sides of the bottom of the fertilizer box 6.

[0069] In order to further optimize the above technical solution, the rear ends of the frame 1 are provided with intertillage shovels 7 located on both sides of the tobacco ridge. The cross section of the intertillage shovel 7 is V-shaped, and the V-shaped tip faces forward.

[0070] Fertilizer is thrown to both sides of tobacco roots after film removal via fertilizer dispenser and conveying pipe, weeding is done in ridges and furrows by intertillage shovel 7, and soil in ridges and furrows is cultivated to the roots of tobacco seedlings to promote the growth of tobacco roots.

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

[0072] The seedling support 4 plays an important role and is composed of two side plates 41 and an arc-shaped plate 42. The arc-shaped plate 42 faces the tractor and forms an "eight" structure, which can gather the leaves of the tobacco seedlings on both sides inward and appropriately press them down to avoid damaging the tobacco seedlings during the film removal process and reduce the obstruction of the tobacco seedlings to the subsequent film removal operation.

[0073] Film shovel 2 is two, is symmetrically arranged on both sides, rear of supporting seedling device 4, and is installed in tilted shape. Under tractor traction, film shovel 2 scoops up film 8, and film 8 moves backward above along the curved surface of film shovel 2.

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

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

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

[0077] A fertilizer box 6 is housed on the top of the front end of the frame 1, and fertilizer delivery pipes 61 are connected to the bottom on both sides, extending to both sides of the tobacco ridge 9. Fertilizer is thrown into the tobacco root both sides after the film is removed through the fertilizer discharger and the delivery pipe.

[0078] Intertillage and soil-raising shovel 7 is located at both sides of frame 1 rear end, is V-shaped, and tip is forward. During operation, when intertillage and soil-raising shovel 7 weeds, ridge soil is cultivated to tobacco seedling root, promotes tobacco root growth.

[0079] This model has a compact structure, easy operation, high reliability, and a high degree of automation. It adopts a tractor-pulled composite operation mode to operate, which not only improves production efficiency and reduces the labor costs and labor intensity of tobacco farmers, but also reduces the number of tractor visits, effectively reducing the compaction damage to the land caused by the tractor, and providing technical support for achieving "double reduction".

[0080] In other embodiments, the contoured self-rolling tobacco field film-removing and intertillage machine can be designed with a detachable structure. For example, the seedling support 4, film shovel 2, film coreless self-rolling mechanism 3, fertilizer box 6, and intertillage shovel 7 can all be designed to be detachably connected to the frame 1, using bolted connections. This detachable and assembled structure can adapt to different farming needs and improve equipment utilization.

[0081] When the film peeling operation is required, the overall structure remains the structure in the above embodiment.

[0082] When the film is peeled off and the tillage and soiling are carried out, the structures related to the film peeling operation, such as the seedling supporter 4 and the film shovel 2, can be removed, and the tillage and soiling shovel 7 can be used to perform multiple soiling operations.

[0083] This structural design changes the defects of traditional structures such as single function and low operational flexibility, and has higher equipment utilization.

[0084] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Reference can be made to the common and similar parts between the various embodiments. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the method description.

[0085] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one 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 limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
