Description

Technical Field

[0001] The utility model relates to a rice film covering rice transplanter with a rice seedling needle integrated with a film hole-punching knife, belonging to the technical field of hole-punching knives. Background Art

[0002] It has been verified that the rice film mulching cultivation method has been highly valued by the country and widely recognized by the industry. In particular, from 2023 to 2024, the demand for rice film mulching has surged across the country. The main reason why the film mulching method has not been promoted on a large scale is that the rice film mulching transplanting machine has not been mature enough and can only be tried on a small scale. Among the multiple technical bottlenecks, the existing "push rod" of the rice transplanter's planting arm cannot pierce all the mulch, causing about 30% of the seedlings to float on the mulch and fail to be inserted into the soil, which is also one of the difficult problems.

[0003] Combining the research and development with the field application effects, we have successively submitted two patent applications for "Synchronous Membrane Hole Opening Mechanism of Rice Film Covering Transplanter" and "Detachable Puncher of Membrane Hole Punching Mechanism of Rice Film Covering Transplanter". These two patent applications have effectively solved the problem of accurately puncturing the mulch before transplanting seedlings to ensure that the seedlings are effectively planted in the soil, and have been tried out well in many areas. The membrane hole opening mechanisms in these two patent applications are both installed on the "push seedling rod". The "Synchronous Membrane Hole Opening Mechanism of Rice Film Covering Transplanter" has the disadvantage of inconvenient maintenance. After wear, it cannot be replaced separately, and the transplanting arm needs to be disassembled. The "Detachable Puncher of Membrane Hole Punching Mechanism of Rice Film Covering Transplanter" can quickly replace the puncher, which is simple and easy, but the processing cost is high. In areas with high soil viscosity, the puncher has the phenomenon of hanging mud, sticking to seedlings, and carrying seedlings during film covering operations, which affects the work quality of the "push seedling rod". Summary of the invention

[0004] The purpose of the utility model is to solve the problems existing in the prior art and further provide a rice film covering transplanter with a rice seedling needle integrated with a film hole opening knife.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] The invention discloses a rice film-covered rice transplanter with a rice seedling needle integrated with a film hole-punching knife, which is composed of a rice seedling needle and a hole-punching knife. The rice seedling needle and the hole-punching knife are fixedly connected as one body. The hole-punching knife is fixed on one side of the front end of the rice seedling needle, and the hole-punching knife and the rice seedling needle are arranged at a right angle.

[0007] The hole-opening knife and the seedling needle are welded into one body.

[0008] The hole-opening knife and the seedling needle are bonded together or fastened together by bolts and nuts.

[0009] The hole-punching knife and the seedling needle are integrated by 3D printing.

[0010] The hole-opening knife and the seedling needle are cast or forged as one body.

[0011] The front end of the hole-opening knife is a toothed blade.

[0012] The toothed blade at the front end of the hole-opening knife is a single-tooth blade, a double-tooth blade or a triple-tooth blade.

[0013] The lengths of the teeth at the front end of the hole-opening knife can be the same or different.

[0014] Beneficial effects of the utility model:

[0015] The utility model is aimed at film-covered planting with high viscosity of field soil, and a new type of seedling needle integrated film hole-opening knife is developed. The "hole-opening knife" is installed on the "seedling needle" to restore the original function of the "seedling pusher". The new device has a more streamlined structure and greatly reduces the processing cost. It not only ensures the advantages of accurate hole opening and convenient disassembly and assembly on the film, but also achieves no mud hanging, no seedling sticking, and no seedling carrying. It can better cope with various agricultural soils such as clay soil and sandy soil in the north and south of my country, and has significantly stronger adaptability to field operations.

[0026] The utility model will be further described in detail below in conjunction with the accompanying drawings: This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method is given, but the protection scope of the utility model is not limited to the following embodiments.

[0027] like Figures 1 to 8 As shown, the rice film transplanter with integrated membrane hole-punching knife of a rice film covering is composed of a rice film transplanter 1, a hole-punching knife 2, a planting arm 3, a rice seedling pushing rod 4 and two bolts 5. The rice seedling 1 and the hole-punching knife 2 are fixedly connected as a whole. The hole-punching knife 2 is fixed to one side of the front end of the rice seedling 1. The hole-punching knife 2 and the rice seedling 1 are arranged at a right angle. Two bolt holes 6 are provided on the rear end of the rice seedling 1. The rear end of the rice seedling 1 is fixed to the upper part of the planting arm 3 by two bolts 5, and the rice seedling pushing rod 4 is slidably connected to the planting arm 3 (the rear end of the rice seedling pushing rod 4 is installed in the planting arm 3 and the forward and backward extension of the rice seedling pushing rod 4 is controlled by the planting arm 3).

[0028] The hole-opening knife 2 and the seedling needle 1 are welded into one body.

[0029] The hole-opening knife 2 and the seedling needle 1 are bonded together or fastened together by bolts and nuts.

[0030] The hole-punching knife 2 and the seedling needle 1 are integrated by 3D printing.

[0031] The hole-opening knife 2 and the seedling needle 1 are cast or forged as one body.

[0032] The front end of the hole-opening knife 2 is a toothed blade 7 .

[0033] The toothed blade 7 at the front end of the hole-opening knife 2 is a single-tooth blade, a double-tooth blade, a triple-tooth blade or a multi-tooth blade (three-tooth blade in the figure).

[0034] The lengths of the teeth at the front end of the hole-opening knife (two teeth or more) can be the same or different, and can be the length of the upper tooth edge or the length of the lower tooth edge.

[0035] The rice film transplanting machine with an integrated seedling needle and a membrane hole-punching knife in the above-mentioned embodiment can be used to punch holes in the film in fields with sticky soil in southern or northern my country. It is not easy for the seedlings to stick to the soil during operation, thus ensuring the efficiency and quality of transplanting. The integrated structure of the seedling needle and the hole-punching knife is easy to replace after damage, without disassembling the transplanting arm. It changes the way of installing the punching mechanism on the seedling pushing rod. It is another new device for realizing the function of opening holes in the film. It is more adaptable and down-to-earth for field operations with different soil types.

[0036] The above are only preferred specific embodiments of the present invention. These specific embodiments are different implementations based on the overall concept of the present invention, and the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a technician familiar with the technical field within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
