Description

Technical Field

[0001] This utility model belongs to the field of film covering technology, specifically relating to an automatic film cutting device for a detachable film covering and seeding machine. Background Technology

[0002] A mulching seeder is an agricultural machine that integrates mulching and sowing functions. It is mainly used to cover crops with mulch during the sowing process to increase crop yield, reduce water evaporation, suppress weed growth, and improve the soil environment.

[0003] When performing mulching and sowing, the film needs to be cut automatically by a blade. However, when encountering thicker or tear-resistant mulch films, or uneven mountainous or hilly terrain, traditional blades cannot effectively and quickly cut the mulch film, requiring repeated operations and reducing efficiency. Therefore, there is an urgent need for a detachable automatic film cutting device for mulching and sowing machines that can effectively cut the mulch film. Utility Model Content

[0004] Based on the above-mentioned technical problems, this utility model provides a detachable automatic film cutting device for a film-covered seeder.

[0005] An automatic film-cutting device for a detachable film-mulching seeder includes a roller beam and a film-mulching roller:

[0006] A cover film, which is wound around a film roller;

[0007] A tilting servo, the tilting servo being connected to a roller beam located on one side;

[0008] Top beam, the bottom of which is connected to a cutting tool assembly;

[0009] Support base, the support base being connected to the top of the roller beam;

[0010] A bottom sleeve is movably connected to a support base, and the flip servo motor drive end is connected to the bottom sleeve.

[0011] A top sliding rod slides on the top of the bottom sleeve, and a top beam connects between a pair of top sliding rods;

[0012] The first hydraulic cylinder is connected to one side of the bottom sleeve, and the telescopic end of the first hydraulic cylinder is connected to one side of the top slide rod.

[0013] A guide roller, which is movably connected between a pair of roller beams;

[0014] A film scraper is connected between a pair of coating rollers.

[0015] In the above technical solution, the tool assembly includes:

[0016] A placement opening is provided at the bottom of the top beam;

[0017] Top frame, with an intermediate frame connected to the middle of the bottom of the top frame;

[0018] A film-cutting knife is connected to the bottom of the intermediate frame. A pair of side posts are connected between the film-cutting knife and the top frame. The pair of side posts are located on both sides of the top frame. A heating plate is connected to one side of the film-cutting knife.

[0019] The top frame is connected to the top beam via a connecting assembly.

[0020] In the above technical solution, the connection component includes:

[0021] Upper docking blocks, a pair of said upper docking blocks are connected to one side of the top frame;

[0022] The lower connecting block, a pair of which are connected to one side of the top beam, and the upper connecting block and the lower connecting block are connected by bolts.

[0023] The above technical solution also includes:

[0024] A blocking rod is connected to one end of the roller beam.

[0025] The above technical solution also includes:

[0026] A limiting block, wherein the limiting block is connected to one side of the first hydraulic cylinder;

[0027] The second hydraulic cylinder is connected to one side of the roller beam, and a top block is connected to the telescopic end of the second hydraulic cylinder.

[0028] The above technical solution also includes:

[0029] A pad block, which is attached to the top of the roller beam.

[0030] The present invention provides a detachable automatic film-cutting device for a mulching seeder, which, compared with the prior art, has the following advantages:

[0031] During use, the combination of the heating plate and the film-cutting blade enables quick and accurate cutting of the mulch film. This not only improves work efficiency but also ensures the quality of film cutting, avoiding the problems of film tearing or unevenness that may occur with traditional mechanical cutting. A scraping frame is set on one side of the film-cutting blade to effectively prevent the mulch film from sticking to the blade, keeping the blade clean and sharp. The blade assembly is connected to the top beam through the upper and lower connecting blocks in the connecting assembly. This design allows for convenient and quick replacement of the blade when it is worn or damaged. The flipping servo can flip and fold the blade assembly in the folding device, reducing the space occupied when not in use. Attached Figure Description
