Description

Technical Field

[0001] This invention relates to the field of film covering machines, specifically a greenhouse anti-deviation film covering machine. Background Technology

[0002] In greenhouse mulching operations, using a mulching machine is an important means to improve efficiency, reduce costs, and enhance work quality, especially suitable for large-scale, standardized greenhouse production scenarios. However, existing mulching machines have limitations in adapting to the randomness of the ground surface, resulting in poor mulching tightness and flatness, lateral wrinkles in the mulch, incomplete mulching, and damage to the mulch, thus requiring manual mulching.

[0003] To address existing shortcomings, a crop mulching machine (application number 2019221753080) was developed, comprising walking wheels, connecting rods, axles, wheel sleeves, a motor, a battery, a positioning and navigation device, a steering mechanism, a central computer control unit, and a mulching device. All components are connected together via connecting rods. There are four walking wheels, two at the front and two at the rear, connected to the motor via a conveyor belt. Driven by the motor, the machine operates. The battery is connected to the motor via wires, providing power. The central computer control unit is the overall control system, connected to each component via data cables, controlling their operation and ensuring smooth completion of tasks. The positioning and navigation device is the route selection and data acquisition system, enabling the machine to operate normally according to predetermined goals. The mulching device is connected to the connecting rods and operates under the control of the central computer control unit. This machine achieves automation and intelligence in crop mulching. A crop sowing and mulching machine with application number 2019102751493 includes a frame, which is a rectangular frame. The inner wall of the frame is equipped with two symmetrical compaction wheels, two film pressing wheels, two mounting plates, two clamping plates, and two ditching rotary tillers. The two mounting plates and two clamping plates are welded to the inner wall of the frame. A film guiding device is installed between the two mounting plates. A roll of mulch film is rotatably clamped between the two clamping plates. The two ditching rotary tillers are rotatably mounted on the inner wall of the frame via a rotating shaft. The film guiding device improves the flatness of the mulch film and can adapt to the laying angle of the mulch film according to both flat planting and ridging planting methods, ensuring the speed of mulch film laying on both sides during mulching. It also improves the pressing effect of the mulch film, effectively preventing lateral wrinkles that could lead to incomplete mulching or damage, thus greatly improving the crop cultivation effect.

[0004] Although the aforementioned film covering machine is convenient for covering and pressing crops, it still has other shortcomings. First, the film covering machine does not fully consider the varying film width requirements of different crop areas inside the greenhouse. The spacing between the pressing rollers cannot be precisely adjusted to match the width of the area to be covered in the greenhouse, which can easily lead to deviations during film covering and make it impossible to cover accurately. Furthermore, the film covering machine does not provide an effective film pressing mechanism or anti-deviation device, resulting in unstable film position during the film covering process, affecting the quality and efficiency of film covering. In addition, the greenhouse ground is often uneven, which can easily impact the pressing rollers and thus affect the film laying effect. Summary of the Invention

[0005] The purpose of this invention is to provide a greenhouse anti-deviation film covering machine to solve the problems mentioned in the background art. Firstly, existing film covering machines on the market do not fully consider the varying film width requirements of different crop areas within the greenhouse. Secondly, the spacing between the pressing rollers cannot be precisely adjusted to match the required film width, easily leading to deviations during film covering and inaccurate coverage. Thirdly, the lack of an effective film pressing mechanism or anti-deviation device results in unstable film position during the covering process, affecting film covering quality and efficiency. Finally, uneven greenhouse floors can easily impact the pressing rollers, further affecting the film laying effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a greenhouse anti-deviation film covering machine, comprising a frame, a connecting frame fixedly installed on the right side of the frame, an mounting plate fixedly connected to the right side of the connecting frame, symmetrically provided sliding grooves on the upper and lower sides of the mounting plate, and rollers fixedly installed at the bottom of the frame; film covering assemblies for tensioning are provided on the top of the front and rear sides of the connecting frame, the film covering assembly includes a rotating shaft seat, a support arm rotatably connected inside the rotating shaft seat, and guide rollers fixedly connected to the bottom of the front and rear sides of the connecting frame; a drive motor body is provided on the front of the mounting plate, a bidirectional screw is fixedly installed on the output shaft of the drive motor body through a coupling, a threaded sleeve is movably connected to the outer wall of the bidirectional screw, sliders are fixedly installed on the inner walls of the upper and lower sides of the threaded sleeve, and a guide assembly for preventing deviation is provided on the right side of the threaded sleeve.

[0007] Preferably, a rotating rod extends through the interior of the support arm, a film-coating roller is fixedly installed on the outer wall of the rotating rod, and a drive assembly for transmission is provided on the outer wall of the front of the rotating rod, the drive assembly including a servo motor body.

[0008] Preferably, the output shaft of the servo motor body is fixedly mounted with a first gear via a coupling, and the servo motor body is located at the top of the frame. A second gear is meshed with the right side of the first gear. A rotating rod is fixedly mounted inside the second gear. The outer wall of the rotating rod is connected to the belt body via a pulley, and the end of the belt body is sleeved on the outer wall of the rotating rod.

[0009] Preferably, the top of the connecting frame is symmetrically and rotatably connected to the body of a first telescopic cylinder, and the output end of the first telescopic cylinder body is rotatably connected to a support arm.

[0010] Preferably, the guide assembly includes a protective shell, and a second telescopic cylinder body is disposed inside the left side of the protective shell. A connecting arm is rotatably connected to the output end of the second telescopic cylinder body. The interior of the connecting arm is connected to a support leg through a rotating connector, and the top of the support leg is connected to the protective shell through a rotating connector. A mounting seat is fixedly installed on the inner wall of the support leg. A strong spring is fixedly connected to the bottom of the mounting seat. A shock absorber is fixedly installed at the bottom of the strong spring. A support frame is fixedly connected to the bottom of the shock absorber. A guide wheel is rotatably connected inside the support frame.

[0011] Preferably, the support arm is driven by the body of the first telescopic cylinder. The support arm and the rotating shaft seat are rotatably connected. The output end of the first telescopic cylinder body will drive the support arm to move through the rotating shaft seat. Since the support arm is connected to the rotating rod, the movement of the support arm will synchronously drive the rotating rod and the coating roller to move, so that the coating roller can tighten or loosen the film to maintain appropriate tension.

[0012] Preferably, the first gear and the second gear are meshed, the second gear is fixedly connected to the rotating rod, and both the rotating rod and the rotating rod are connected to the belt body for transmission. The rotation of the first gear will drive the second gear to mesh and rotate. The rotating rod is fixedly installed inside the second gear, so that the rotation of the second gear will drive the rotating rod to rotate synchronously.

[0013] Preferably, the threaded sleeve and the bidirectional screw are movably connected, and the outer wall of the bidirectional screw is provided with a bidirectional thread structure. The threaded sleeve and the slider are tightly fitted, and the slider and the groove are slidably connected. During the movement of the threaded sleeve, the slider fixed on the inner wall of its upper and lower sides will slide in the corresponding groove on the mounting plate, which increases the guidance and stability of the movement of the threaded sleeve and ensures that the threaded sleeve can move accurately along the axial direction of the bidirectional screw.

[0014] Preferably, the support leg and the connecting arm are rotatably connected, and the connecting arm and the protective shell are movably connected. The connecting arm drives the support leg to move downward inside the protective shell, and the support leg then drives the guide wheel to press on the film. When the film is used to cover the required area of ​​the greenhouse, the guide wheel can compact the film and prevent the film from deviating.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The greenhouse anti-deviation film covering machine is equipped with a bidirectional screw, a threaded sleeve and a protective shell, which facilitates the precise adjustment of the spacing of the guide wheels to match the width of the area to be covered in the greenhouse, thereby achieving precise film covering. It is also equipped with a connecting arm, a support leg and a guide wheel to press the film and prevent it from deviating. Furthermore, it is equipped with a strong spring to buffer the guide wheels, reduce the film deviation caused by uneven ground, and improve the anti-deviation effect. At the same time, it is equipped with a first telescopic cylinder body, a support arm and a film covering roller to facilitate the adjustment of the tension of the film on the film covering roller. The specific details are as follows. 1. A bidirectional screw, threaded sleeve, and protective shell are provided. The threaded sleeve connected to the bidirectional screw is driven by the drive motor to move closer or further apart. The threaded sleeve simultaneously drives the support legs inside the protective shell to move to both sides of the film covering position, which is connected to the guide wheels. This allows for precise adjustment of the spacing of the guide wheels to match the width of the area in the greenhouse that needs to be covered with film, thereby achieving precise film covering and avoiding uneven or inaccurate film coverage.

[0016] Furthermore, a connecting arm, a support leg, and a guide wheel are provided. The second telescopic cylinder body drives the support leg connected to the connecting arm to move downward inside the protective shell. The support leg then drives the guide wheel to press against the membrane, or drives the guide wheel connected to the support leg to move upward for retraction, thereby compacting the membrane and preventing it from deviating.

[0017] Furthermore, a powerful spring is installed. The elasticity of the spring absorbs the impact force generated by uneven ground, thereby buffering the guide wheel and reducing the phenomenon of membrane deviation caused by uneven ground, thus improving the anti-deviation effect.

[0018] 2. A first telescopic cylinder body, a support arm, and a coating roller are provided. The first telescopic cylinder body drives the support arm to move through the rotating shaft seat. The support arm synchronously drives the rotating rod and the coating roller to move, so that the coating roller can tighten or loosen the film to maintain appropriate tension. This facilitates the adjustment of the tension of the film on the coating roller and ensures that the film remains flat and wrinkle-free during the coating process. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-9 The present invention provides the following technical solution: Example 1: To address the problems of existing film covering machines on the market, such as insufficient consideration of varying film width requirements for different crop areas within greenhouses, inaccurate film application due to the inability to precisely adjust the spacing of the pressing rollers to match the required film width, and the lack of effective film pressing mechanisms or anti-deviation devices leading to film instability and affecting film quality and efficiency, as well as uneven greenhouse floors facilitating impact on the pressing rollers and further affecting film laying, this example discloses the following technical content for a greenhouse anti-deviation film covering machine. (See attached document for details.) Figure 1 -Appendix Figure 2 and attached Figure 5 -Appendix Figure 9 The system includes a frame 1, a connecting frame 2 fixedly mounted on the right side of the frame 1, a mounting plate 15 fixedly connected to the right side of the connecting frame 2, and symmetrically provided sliding grooves 16 on the upper and lower sides of the mounting plate 15. Rollers 30 are fixedly mounted on the bottom of the frame 1. Tensioning film-coating assemblies are provided on the top of the front and rear sides of the connecting frame 2. The film-coating assemblies include a rotating shaft seat 3, with a support arm 4 rotatably connected inside the rotating shaft seat 3. Guide rollers 14 are fixedly connected to the bottom of the front and rear sides of the connecting frame 2. A drive motor body 17 is provided on the front of the mounting plate 15. A bidirectional screw 18 is fixedly mounted on the output shaft of the drive motor body 17 via a coupling. A threaded sleeve 19 is movably connected to the outer wall of the bidirectional screw 18. Slider blocks 20 are fixedly mounted on the inner walls of the upper and lower sides of the threaded sleeve 19. A guide assembly for preventing deviation is provided on the right side of the threaded sleeve 19. The guide assembly includes a protective shell 21, with a second extension inside the left side of the protective shell 21. The second telescopic cylinder body 22 has a connecting arm 23 rotatably connected to its output end. The interior of the connecting arm 23 is connected to the support leg 24 via a rotating connector, and the top of the support leg 24 is connected to the protective shell 21 via a rotating connector. A mounting base 25 is fixedly installed on the inner wall of the support leg 24. A strong spring 26 is fixedly connected to the bottom of the mounting base 25. A shock absorber 27 is fixedly installed at the bottom of the strong spring 26. A support frame 28 is fixedly connected to the bottom of the shock absorber 27. A guide wheel 29 is rotatably connected inside the support frame 28. The threaded sleeve 19 is movably connected to the bidirectional screw 18, and the outer wall of the bidirectional screw 18 is provided with a bidirectional thread structure. The threaded sleeve 19 is tightly fitted to the slider 20, and the slider 20 is slidably connected to the slide groove 16. The support leg 24 is rotatably connected to the connecting arm 23, and the connecting arm 23 is movably connected to the protective shell 21.

[0023] Before the film covering machine operates inside the greenhouse, the operator pulls the film wound on the film covering roller 6, so that the film passes under the guide roller 14 and is positioned below the two guide wheels 29. At this point, the film is ready to cover the greenhouse, and its position roughly corresponds to the area on the greenhouse that needs to be covered. Based on the width of the area to be covered, the operator starts the drive motor body 17 through the external control board, causing the output shaft of the drive motor body 17 to drive the bidirectional screw 18 to rotate within the mounting plate 15. Because the outer wall of the bidirectional screw 18 is provided with a bidirectional thread structure, when the bidirectional screw 18 rotates, it will drive the threaded sleeve connected by the thread. The threaded sleeve 19 moves in a near or far manner. During the movement of the threaded sleeve 19, the sliders 20 fixed on the inner walls of its upper and lower sides slide in the corresponding grooves 16 on the mounting plate 15, increasing the guidance and stability of the movement of the threaded sleeve 19. This ensures that the threaded sleeve 19 can move accurately along the axial direction of the bidirectional screw 18. The threaded sleeve 19 synchronously drives the protective shell 21 to move. The guide wheel 29 is connected to the protective shell 21 through the support leg 24. Therefore, the guide wheel 29 will also move with it until it moves to both sides of the appropriate covering position, realizing the precise adjustment of the spacing of the guide wheel 29 to match the width of the area in the greenhouse that needs to be covered. This achieves precise film covering, avoiding uneven or inaccurate coverage. Then, based on the height of the covering position, the operator activates the second telescopic cylinder body 22 via an external control panel. The output end of the second telescopic cylinder body 22 moves the connecting arm 23, which in turn moves the support leg 24 downwards within the protective shell 21. The support leg 24 then moves the guide wheel 29 to press against the film. When the film is covering the required area of ​​the greenhouse, the guide wheel 29 compacts the film, preventing it from shifting. During the film covering process, if uneven ground is encountered, the guide wheel 29... The guide wheel 29 will be subjected to a certain impact force. At this time, the strong spring 26 connected to the support frame 28 will absorb these impact forces, thereby buffering the guide wheel 29. This can reduce the film deviation caused by uneven ground and improve the anti-deviation effect. After the laminating machine finishes its work, the operator will start the second telescopic cylinder body 22 again through the external control panel to drive the connecting arm 23 to move back. This will cause the connecting arm 23 to drive the support leg 24 connected to the rotating component to rotate upward in the protective shell 21, thereby retrieving the guide wheel 29 connected to the support leg 24 so that the laminating machine can move or perform the next laminating operation.

[0024] Example 2: The greenhouse anti-deviation film covering machine in this example discloses the following technical content, which facilitates the adjustment of the film tension on the film covering roller 6, ensuring that the film remains flat and wrinkle-free during the film covering process. Please refer to the attached document. Figure 1 -Appendix Figure 4A rotating rod 5 runs through the interior of the support arm 4. A coating roller 6 is fixedly installed on the outer wall of the rotating rod 5. A drive assembly for transmission is provided on the outer wall of the front of the rotating rod 5. The drive assembly includes a servo motor body 7. A first gear 8 is fixedly installed on the output shaft of the servo motor body 7 through a coupling. The servo motor body 7 is located at the top of the frame 1. A second gear 9 is meshed with the right side of the first gear 8. A rotating rod 10 is fixedly installed inside the second gear 9. The outer wall of the rotating rod 10 is connected to the belt body 11 through a pulley. The end of the belt body 11 is fitted with a... On the outer wall of the rotating rod 5, the top of the connecting frame 2 is symmetrically and rotatably connected to the first telescopic cylinder body 12. The output end of the first telescopic cylinder body 12 is rotatably connected to the support arm 4. The outer wall of the first telescopic cylinder body 12 is fixedly installed with the connecting plate 13. The support arm 4 is driven by the first telescopic cylinder body 12. The support arm 4 and the rotating shaft seat 3 are rotatably connected. The first gear 8 and the second gear 9 are meshed. The second gear 9 and the rotating rod 10 are fixedly connected. The rotating rod 10 and the rotating rod 5 are both connected to the belt body 11 for transmission.

[0025] When the film is applied to the areas of the greenhouse requiring covering, the operator starts the servo motor 7 via an external control panel. This causes the output shaft of the servo motor 7 to rotate, which in turn drives the first gear 8 to rotate synchronously via a coupling. The rotation of the first gear 8 then drives the second gear 9 to mesh and rotate. A rotating rod 10 is fixedly installed inside the second gear 9, causing it to rotate synchronously. The rotation of the rotating rod 10 drives the belt 11, which in turn rotates the rotating rod 5. This rotation of the rotating rod 5 then drives the covering roller 6 to rotate, releasing the film wound on it. Simultaneously, the operator pushes the covering machine... The roller 30 is driven by force to move the entire structure, so that the film can be continuously covered in the required position of the greenhouse. This realizes the automatic rotation and film release of the film covering roller 6, improving the film covering efficiency. According to the tension of the film on the film covering roller 6, the operator starts the first telescopic cylinder body 12 through the external control board. The output end of the first telescopic cylinder body 12 drives the support arm 4 to move through the rotating shaft seat 3. Since the support arm 4 is connected to the rotating rod 5, the movement of the support arm 4 will synchronously drive the rotating rod 5 and the film covering roller 6 to move, so that the film covering roller 6 can tighten or loosen the film to maintain appropriate tension. This makes it easy to adjust the tension of the film on the film covering roller 6 and ensure that the film remains flat and wrinkle-free during the film covering process.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
