Description

Technical Field

[0001] This utility model relates to the field of mulching technology, and in particular to a mulching device for corn seeding on the film side. Background Technology

[0002] The most prominent effect of mulching corn is to increase soil temperature and retain moisture, compensating for deficiencies in temperature, light, and water resources. It generally increases soil temperature, enhances corn's frost resistance, and relatively extends the frost-free period. Therefore, mid-to-late maturing, high-yielding varieties with longer growth periods and greater yield potential can be selected. Mulching also advances the corn planting date, accelerates the growth process, and promotes earlier emergence and maturity.

[0003] In particular, the development of corn film-side seeders began in 2012. This technology has been widely used in Shanxi, Shaanxi, Inner Mongolia, Hebei, and other regions, with a cumulative planting area exceeding 4 million mu. The integrated film-side seeder technology solves several problems in traditional mulching methods, such as straw clogging, film wrinkles, and uneven soil coverage, by using non-ditching mulch and side-strip sowing. This technology not only improves sowing efficiency but also reduces labor input, increases seedling emergence rate, and enhances crop resistance to premature aging. After applying the integrated film-side seeder technology, farmers' production costs are significantly reduced, and the operating speed is 2-3 times faster than conventional film-perforated planting, saving approximately 100 yuan per mu in labor for seedling removal and placement. Furthermore, this technology helps reduce mulch usage, increases residual film recycling rate, and achieves green and sustainable development in corn production. With the continuous maturation of technology and the expansion of its application scope, corn film-side planters are expected to be used in more regions, especially in specific environments such as the agro-pastoral wind-blown sandy areas in the north. This technology can effectively solve problems such as large amounts of mulch film used and difficulty in recycling residual film, further promoting the efficient and sustainable development of corn production. However, the planting speed of current planters needs to be further improved. The market mainly focuses on single-film (2-row) planting, while double-film (4-row) planters have many shortcomings. For uneven ground and plots with single-film (2-row) or double-film (4-row) planting, there are still plots where single-film (2-row) planting is not possible. To address these issues, the film covering device can be divided into two separate film covering units according to different terrain levels, without affecting each other. At the same time, the film covering device can fold one unit over the other for film covering.

[0004] Therefore, a corn mulching device that is highly efficient and labor-saving needs to be researched. Utility Model Content

[0008] As a further embodiment of this utility model: the grooving mechanism includes a second support, and the number of the second supports is set in two sets, with a grooving disc rotatably connected to the inner side of each of the two sets of second supports.

[0010] As a further embodiment of this utility model: the film pressing and fixing mechanism includes an inner crossbar, which is fixedly connected to the inner side of the first fixed bracket. Two sets of inclined fixing blocks are fixedly connected to the outer side of the inner crossbar. Two sets of inner rotating arms are rotatably connected below the inner crossbar.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model integrates five key processes—ridge making, trenching, film laying, film pressing, and soil covering—into a continuous automated process. During operation, the ridge making roller first gathers the soil to form a regular ridge. The trenching disc then precisely trenches the top of the ridge. The film covering mechanism immediately lays the film. The film pressing wheel dynamically adapts to the terrain through a spring pressure mechanism to press the film with constant force to ensure that it adheres tightly to the ridge surface outline. Finally, the soil covering disc rotates and pushes soil to tightly cover the film edge, forming a windproof soil layer. This avoids the traditional intermittent manual operation, greatly improves the film covering speed, and ensures the quality of film laying.

[0014] 2. This utility model features a double-film structure. By adding a fixing frame structure, the film area is increased, allowing for the completion of twice or more work in the same amount of time, thus significantly improving work efficiency. Both the first and second fixing brackets can be bent at 90 degrees and can be folded when not in use. Adjustments can be made according to actual conditions, and the back-and-forth adjustment between single and double film covering greatly enhances the practical value of the device.

[0026] The working principle of this utility model is as follows: The tractor provides traction through the three-point suspension connection of the upper mounting frame 22 and the lower mounting frame 23 to the power connection mechanism 2. During the forward movement of the device, the ridging roller 32 of the soil gathering mechanism 3 rolls and gathers the soil into a regular soil mound. Immediately afterwards, the trenching disc 42 of the trenching mechanism 4 rotates outward and cuts into the sides of the soil mound to open trenches. Subsequently, the film covering mechanism 5 releases the film with the film hanging rod 53 (with film roller installed), covering the trenched soil mound. The film is then immediately processed by the film pressing and fixing mechanism 6. Under the constant pressure of the supporting spring 66, the pressing roller 64 firmly presses the film onto the contour of the soil ridge surface. Finally, the covering disc 72 of the film covering mechanism 7 located at the rear of the device rotates, pushing the soil in the trench or on both sides inward, evenly covering and compacting the two edges of the film, completing the windproof and film-fixing operation. When the operation is finished and it needs to be retracted, the hydraulic cylinder 13 is controlled to retract, pulling the second fixed support 12 and rotating the film covering mechanism 7 towards the first fixed support 11 to fold and retract the device. The bottom of the entire device is lifted off the ground and becomes compact. Seeding can be carried out by fixing a seed metering device on the crossbeam behind the second fixed support.
