Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural sowing auxiliary machinery, and in particular relates to a sowing row spacing adjustable rolling furrow pressing device. Background Art

[0002] At present, farmland sowing can be divided into manual sowing and mechanical sowing. Traditional manual sowing involves field operations such as furrowing, sowing, fertilizing, applying herbicides, covering the soil, and pressing. The advantages are simple operation and low requirements for production tools. The disadvantages are: more labor, large amount of seeds, difficulty in controlling row spacing and plant spacing, often excessive dense planting or uneven density, uneven seedling emergence, and labor-consuming and time-consuming. Although mechanical sowing has improved the sowing amount and seeding uniformity, it will also be affected by factors such as soil conditions. There are also problems such as large amount of seeds and unequal spacing. There are also problems such as fertilization and uneven application of medicines during sowing. In addition, existing seeders cannot be effectively applied to sowing environments with wet and sticky soil and poor land preparation quality, and the sowing row spacing of these seeders is fixed and cannot be adjusted. Therefore, there is a need for a rolling furrow pressing device with adjustable sowing row spacing suitable for sowing environments such as wet and sticky soil and poor land preparation quality.

[0019] like Figure 1-Figure 5 As shown, the utility model provides a rolling ditch pressing device with adjustable sowing row spacing, which comprises a power pressing roller 11, on which a plurality of power pressing rings 12 are slidably arranged, and the power pressing ring 12 is provided with a plurality of mounting holes 15 in the radial direction, in which countersunk screws are installed; specifically, three mounting holes 15 are provided on each power pressing ring 12, in which countersunk screws are installed, and after adjusting the position of the power pressing ring 12, a screwdriver is used to tighten the countersunk screws so that the countersunk screws are pressed against the inner wall of the power pressing roller 11, thereby completing the fixation of the power pressing ring 12.

[0020] The power pressing ring 12 includes a pressing ring portion 1 and chamfered portions 2 arranged on both sides of the pressing ring portion 1. The two sides of the power pressing roller 11 are connected with a scraper assembly for scraping clay off the power pressing ring 12 through the first bearing 5 and the second bearing. The chamfered portions 2 on both sides of the pressing ring portion 1 can ensure that the bottom surface of the seed groove forms a slope that tilts downward from both sides to the middle, which not only saves more effort when pressing the groove, but also the seeds will roll to the bottom surface when falling into the seed groove, and the seedlings will be more neat after germination.

[0021] The power pressure roller 11 is provided with a translation slide 13 , and the power pressure ring 12 is provided with a translation slide bar 16 .

The scraper plate 7 is provided with a groove with an opening facing downward, and a plurality of adjustment holes 3 are provided on both sides and the middle of the groove on the scraper plate 7, and the scraper 8 is installed in the groove through the adjustment holes 3; the scraper frame 6 is connected to the power pressure roller 11 through the first bearing 5 and the second bearing, so that the power pressure roller 11 does not affect the scraper frame 6 when rotating, and the rotation of the power pressure roller 11 drives the rotation of the power pressure ring 12, so that the clay adhered to the power pressure ring 12 is scraped off by the scraper 8. During use, the scraper 8 will have a certain degree of wear. By setting a plurality of adjustment holes 3, the scraper 8 can be extended and retracted up and down. When the scraper 8 is seriously damaged, the scraper 8 can be disassembled by screws to move it downward to work again. It is convenient and quick to avoid the trouble of replacing the scraper 8.

[0023] The inner wall of the power pressing ring 12 is close to the outer wall of the power roller, the thickness of the power pressing ring 12 is 2 to 4 cm, the width of the power pressing ring 12 is 7 to 10 cm, and the number of the power pressing rings 12 is 6. Specifically, the thickness of the power pressing ring 1212 is set to 3 cm, and the width is set to 8 cm. The pressed groove is 8 cm wide and 3 cm deep, which is conducive to seedling emergence. It can also be set at will according to actual needs to adapt to different widths and depths.

[0024] When the utility model is in use, the furrow pressing assembly of the present application can be installed on the rear part of the rotary tiller for furrow pressing. After the rotary tiller completes tilling the land, as the tractor moves forward, the power pressing roller 11 and the power pressing ring 12 rotate simultaneously to form a sowing furrow. The power pressing ring 12 is set to press the furrow to ensure the consistency of the seed furrow, and the power pressing ring 12 is slidably set on the power pressing roller 11. The sowing row spacing can be adjusted by sliding and translating the power pressing ring 12, which can achieve both equidistant sowing and wide and narrow row sowing, thereby improving the applicability of the device. Specifically, the power pressing ring 12 is slid to an appropriate row spacing by translating the slide bar 16 and the slideway 13. After the adjustment is completed, the inner wall of the power pressing roller 11 is supported by the countersunk top screw in the mounting hole 15 to fix the power pressing ring 12, thereby achieving the adjustment of the sowing row spacing. The utility model has a simple structure, is convenient and quick to operate, and has high feasibility. The power pressing ring 12 is used to press the groove to ensure the consistency of the seed groove, and a scraper assembly is arranged on the power pressing roller 11 to scrape off the clay adhering to the power pressing ring 12 while pressing the groove, thereby ensuring the smooth progress of the sowing work, and effectively solving the technical problem that the existing seeder cannot be effectively applied to the sowing environment with wet and sticky soil and low land preparation quality.

[0025] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the protection scope of the technical solution of the utility model.
