Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a film spreading device for a film-covered rice transplanter. Background Technology

[0002] To effectively suppress weed growth during rice plant development and increase rice yield and quality, the current common practice is to lay biodegradable film in the paddy field before transplanting rice seedlings, followed by punching holes in the film and transplanting. To improve the efficiency and quality of rice mulching operations, traditional rice transplanters need to be equipped with film-spreading devices.

[0003] Most existing rice transplanters using mulching machines employ a single row of straight mulching rollers for spreading the film. This design prevents the biodegradable film from spreading properly, leaving the edges unsecured and prone to deviation during spreading. This results in significant losses during the mulching process, requiring manual adjustment of the film, which prolongs operation time and increases costs. Therefore, a new technical solution is urgently needed to address at least one of these problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a film spreading device for a mulched rice transplanter, which solves the technical problem that the biodegradable film is prone to deviation on both sides during spreading, thereby reducing losses and improving work efficiency.

[0007] The second intermediate contouring film spreading assembly includes a third support and a fourth support arranged in parallel intervals, and at least two second intermediate contouring film spreading rollers arranged side by side between the third support and the fourth support. The first intermediate contouring film spreading roller assembly and the second intermediate contouring film spreading roller assembly are arranged side by side.

[0008] The first side contouring film spreading assembly includes a fifth support and a sixth support arranged in parallel and spaced apart, and at least two first side contouring film spreading rollers arranged side by side between the fifth support and the sixth support. The first side contouring film spreading assembly is located on one side of the outer periphery of the first middle contouring film spreading assembly, and the first side contouring film spreading rollers form an angle with the first middle contouring film spreading rollers.

[0009] The second side conformal film spreading assembly includes a seventh support and an eighth support arranged in parallel intervals, and at least two second side conformal film spreading rollers arranged side by side between the seventh support and the eighth support. The second side conformal film spreading assembly is located on one side of the outer periphery of the second middle conformal film spreading assembly, and the second side conformal film spreading rollers form an angle with the second middle conformal film spreading rollers.

[0010] The connecting pipe is fixedly connected to the first to eighth brackets.

[0011] As a preferred technical solution, the connecting pipe includes an intermediate pipe section, a first bend transition pipe section and a second bend transition pipe section disposed at both ends of the intermediate pipe section, a first side pipe section disposed at one end of the first bend transition pipe section opposite to the intermediate pipe section, and a second side pipe section disposed at one end of the second bend transition pipe section opposite to the intermediate pipe section. The first to fourth supports are fixedly connected to the intermediate pipe section, the fifth and sixth supports are fixedly connected to the first side pipe section, and the seventh and eighth supports are fixedly connected to the second side pipe section.

[0012] As a preferred technical solution, the intermediate pipe section is provided with an intermediate bracket, a first side bracket and a second side bracket respectively disposed at both ends of the intermediate pipe section, the intermediate bracket being located between the first intermediate contour film spreading assembly and the second intermediate contour film spreading assembly, the first side bracket being located between the first intermediate contour film spreading assembly and the first side contour film spreading assembly, and the second side bracket being located between the second intermediate contour film spreading assembly and the second side contour film spreading assembly, with a mounting bracket provided at one end of the intermediate bracket.

[0013] As a preferred technical solution, the mounting bracket is provided with a sensing cable, and the first side bracket and the second side bracket are respectively provided with a first contour cable and a second contour cable.

[0014] As a preferred technical solution, an intermediate support frame is provided at the other end of the intermediate bracket.

[0015] As a preferred technical solution, one end of the first side bracket and the second side bracket are respectively provided with a first side support frame and a second side support frame.

[0016] As a preferred technical solution, the intermediate support frame, the first side support frame, and the second side support frame are provided with a support pipe.

[0017] As a preferred technical solution, the outer sides of the first side support frame and the second side support frame are respectively provided with a first reinforcing plate and a second reinforcing plate.

[0020] The beneficial effects of this utility model are:

[0021] 1) The first side contouring film spreading roller forms an angle with the first middle contouring film spreading roller, and the second side contouring film spreading roller forms an angle with the second middle contouring film spreading roller. This creates an overall "waist drum" structure. The first and second side contouring film spreading rollers can prevent the degradation film from deviating on both sides, eliminating the need for frequent adjustments by workers, improving work efficiency, and reducing degradation film loss. The number of the first middle contouring film spreading roller, the second middle contouring film spreading roller, the first side contouring film spreading roller, and the second side contouring film spreading roller should be at least two, forming at least a double-row structure for better film spreading effect.

[0022] 2) The induction cable can be used in conjunction with the contour valve to sense the elevation of the field. The contour cable is then connected to the hydraulic pulling device to raise and lower the film spreading device, thus adapting to different terrains and making it highly adaptable to field operations.

[0023] 3) The intermediate support frame, the first side support frame, and the second side support frame work together to connect the support pipe, which facilitates the subsequent installation of the rice transplanting device and provides good overall support stability;

[0024] 4) When the angle between the first intermediate conforming film spreading roller and the first side conforming film spreading roller is greater than 175°, it cannot effectively prevent the degradation film from deviating on both sides. When the angle between the first intermediate conforming film spreading roller and the first side conforming film spreading roller is less than 170°, the degradation film is easily wound onto the first side conforming roller, affecting the film spreading.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0031] Please see Figures 1-3This utility model provides a film spreading device for a mulched rice transplanter, including a first intermediate contour film spreading assembly, a second intermediate contour film spreading assembly, a first side contour film spreading assembly, a second side contour film spreading assembly, and a connecting pipe 13. The first intermediate contour film spreading assembly includes a first support 1 and a second support 2 arranged in parallel intervals, and at least two first intermediate contour film spreading rollers 3 arranged side by side between the first support 1 and the second support 2. The second intermediate contour film spreading assembly includes a third support 4 and a fourth support 5 arranged in parallel intervals, and at least two second intermediate contour film spreading rollers 6 arranged side by side between the third support 4 and the fourth support 5. The first intermediate contour film spreading roller 3 assembly and the second intermediate contour film spreading roller 6 assembly are arranged side by side. The first side contour film spreading assembly includes a fifth support 7 and a sixth support 8 arranged in parallel intervals, and at least two first side contour film spreading rollers 9 arranged side by side between the fifth support 7 and the sixth support 8. The component is located on one side of the outer periphery of the first intermediate contouring film spreading assembly. The first side contouring film spreading roller 9 forms an angle with the first intermediate contouring film spreading roller 3. The second side contouring film spreading assembly includes a seventh support 10 and an eighth support 11 arranged in parallel intervals, and at least two second side contouring film spreading rollers 12 arranged side by side between the seventh support 10 and the eighth support 11. The second side contouring film spreading assembly is located on one side of the outer periphery of the second intermediate contouring film spreading assembly. The second side contouring film spreading roller 12 forms an angle with the second intermediate contouring film spreading roller 6. The first to eighth supports 11 are fixedly connected to the connecting pipe 13. The first intermediate contouring film spreading roller 3 is rotatably connected to the first support 1 and the second support 2 respectively. The second intermediate contouring film spreading roller 6 is rotatably connected to the third support 4 and the fourth support 5 respectively. The first side contouring film spreading roller 9 is rotatably connected to the fifth support 7 and the sixth support 8 respectively. The second side contouring film spreading roller 12 is rotatably connected to the seventh support 10 and the eighth support 8 respectively.

[0032] The first side contouring film spreading roller 9 forms an angle with the first middle contouring film spreading roller 3, and the second side contouring film spreading roller 12 forms an angle with the second middle contouring film spreading roller 6. This gives the whole structure a "waist drum" shape. The first side contouring film spreading roller 9 and the second side contouring film spreading roller 12 can prevent the degradation film 33 from deviating on both sides, eliminating the need for workers to frequently get off the machine to adjust it, improving work efficiency and reducing the loss of degradation film 33. The number of the first middle contouring film spreading roller 3, the second middle contouring film spreading roller 6, the first side contouring film spreading roller 9 and the second side contouring film spreading roller 12 is at least 2, that is, at least forming a double row structure, which results in a better film spreading effect.

[0033] like Figures 1-3As shown, depending on the length of the degradable film 33, the number of the first intermediate contouring film spreading roller 3, the second intermediate contouring film spreading roller 6, the first side contouring film spreading roller 9, and the second side contouring film spreading roller 12 can also be set to 3 or 4. The first intermediate contouring film spreading roller 3, the second intermediate contouring film spreading roller 6, the first side contouring film spreading roller 9, and the second side contouring film spreading roller 12 are arranged according to the unfolding direction of the degradable film 33.

[0034] like Figures 1-3 As shown, the connecting pipe 13 includes an intermediate pipe section 1301, a first bend transition pipe section 1302 and a second bend transition pipe section 1303 disposed at both ends of the intermediate pipe section 1301, a first side pipe section 1304 disposed at the end of the first bend transition pipe section 1302 opposite to the intermediate pipe section 1301, and a second side pipe section 1305 disposed at the end of the second bend transition pipe section 1303 opposite to the intermediate pipe section 1301. The first to fourth supports 5 are fixedly connected to the intermediate pipe section 1301, and the fifth... Support 7 and sixth support 8 are fixedly connected to the first side tube section 1304, and seventh support 10 and eighth support 11 are fixedly connected to the second side tube section 1305. The first turning transition tube section 1302 facilitates the formation of an angle between the first side tube section 1304 and the middle tube section 1301. Thus, after the fifth support 7 and sixth support 8 are installed on the first side tube section 1304, the first side contouring film spreading roller 9 can form an angle with the first middle contouring film spreading roller 3. The principle of the second side tube section 1305 is the same as that of the first side tube section 1304.

[0035] like Figures 1-3As shown, the intermediate pipe section 1301 is provided with an intermediate bracket 14, a first side bracket 15 and a second side bracket 16 respectively disposed at both ends of the intermediate pipe section 1301. The intermediate bracket 14 is located between the first intermediate contour film spreading assembly and the second intermediate contour film spreading assembly. The first side bracket 15 is located between the first intermediate contour film spreading assembly and the first side contour film spreading assembly. The second side bracket 16 is located between the second intermediate contour film spreading assembly and the second side contour film spreading assembly. One end of the intermediate bracket 14 is provided with a mounting bracket 1401. Further, the mounting bracket 1401 is provided with a sensing cable 17. The first side bracket 15 and the second side bracket 16 are respectively provided with a first contour cable 18 and a second contour cable 19. The sensing cable 17 and the mounting bracket 1401 are connected to the intermediate bracket 14 by a pin. 7 is installed on the mounting frame 1401. The first contouring cable 18 is connected to the first side bracket 15 by a pin, and the second contouring cable 19 is connected to the second side bracket 16 by a pin. The sensing cable 17 is generally connected to the contouring valve. The first contouring cable 18 and the second contouring cable 19 are each connected to a hydraulic pulling device. The contouring valve is a sensing device that can sense the height of the field and feed the information back to the control system on the rice transplanter. Then, the control device controls the hydraulic pulling device to pull the contouring cable to lift. Because of the first side bracket 15 and the second side bracket 16, the first side bracket 15 and the second side bracket 16 will drive the entire film spreading device to lift. When the terrain of the field becomes lower, the hydraulic pulling device lowers the contouring cable, and the first side bracket 15 and the second side bracket 16 descend, driving the entire film spreading device to descend, thus adapting to different terrains and having strong adaptability to field operations.

[0036] like Figures 1-3 As shown, an intermediate support frame 20 is provided at the other end of the intermediate bracket 14. The intermediate bracket 14 and the intermediate support frame 20 are connected by a pin. Furthermore, a first side support frame 21 and a second side support frame 22 are respectively provided at one end of the first side bracket 15 and the second side bracket 16. The first side support frame 21 and the second side support frame 22 are respectively connected to the first side bracket 15 and the second side bracket 16 by a pin. Furthermore, a support pipe is straddling the intermediate support frame 20, the first side support frame 21 and the second side support frame 22. The support pipe is welded to the intermediate support frame 20, the first side support frame 21 and the second side support frame 22. The intermediate support frame 20, the first side support frame 21 and the second side support frame 22 form a three-point support for the support pipe, which facilitates the subsequent installation of the rice transplanting device and provides good overall support stability.

[0037] like Figures 1-3As shown, the first side support frame 21 and the second side support frame 22 are respectively provided with a first reinforcing plate 23 and a second reinforcing plate 24 on their outer sides. The first side support frame 21 and the second side support frame 22 are generally two-piece structures. The first reinforcing plate 23 and the second reinforcing plate 24 can respectively strengthen the strength of the first side support frame 21 and the second side support frame 22.

[0038] like Figures 1-3 As shown, the first to eighth brackets 11 are respectively fixedly provided with the first to eighth sleeves 32 on their lower sides. The intermediate pipe section 1301 passes through the first sleeve 25, the second sleeve 26, the third sleeve 27 and the fourth sleeve 28. The first side pipe section 1304 passes through the fifth sleeve 29 and the sixth sleeve 30. The second side pipe section 1305 passes through the seventh sleeve 31 and the eighth sleeve 32, which facilitates the positioning and installation of the connecting pipe 13.

[0039] like Figures 1-3 As shown, the angle between the first intermediate contouring film spreading roller 3 and the first side anti-contact film spreading roller is 170°-175°, and the angle between the second intermediate contouring film spreading roller 6 and the second side anti-contact film spreading roller is 170°-175°. When the angle between the first intermediate contouring film spreading roller 3 and the first side anti-contact film spreading roller is greater than 175°, it cannot effectively prevent the degradation film 33 from deviating on both sides. When the angle between the first intermediate contouring film spreading roller 3 and the first side contouring film spreading roller 9 is less than 170°, the degradation film 33 is easily wound onto the first side contouring roller, affecting the film spreading. In specific installation, the angle between the first intermediate contouring film spreading roller 3 and the first side anti-contact film spreading roller and the angle between the second intermediate contouring film spreading roller 6 and the second side anti-contact film spreading roller are equal.

[0040] The above embodiments are merely descriptions for clearly illustrating the present utility model, and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all implementations here, and the obvious variations or modifications derived therefrom are still within the protection scope of the present utility model.
