Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to a ridging and shaping device for ridging operations. Background Technology

[0002] The ridging and sowing machines widely used in my country typically have combined ridging and sowing functions, enabling integrated ridging and sowing operations with advantages such as high efficiency and low operating costs. However, when used in hilly and mountainous areas, due to small plots, heavy clay soil, and relatively small (low-power) tractors, these machines often require miniaturization and weight reduction. Especially in applications requiring combined ridging and sowing operations for crops like peanuts, the height, width, and flatness of the ridges after operation often fail to meet agronomical requirements, resulting in inconsistent spacing and depth of sown plants, affecting seedling uniformity and consequently, crop yield. To improve sowing results, some ridging and shaping devices have been proposed, such as the Chinese utility model patent application number CN201220369002.4, entitled "A Ridging and Shaping Component." However, existing ridging and shaping devices suffer from complex structures and poor reliability, making it difficult to meet the needs of different working conditions. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a simple and high-performance ridging and shaping device for ridging operations, so as to improve the sowing effect and performance of the ridging seeder.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a ridging and shaping device for ridging operations, including a frame, a cutter roller, a ridging scraper and a leveler are arranged sequentially on the frame facing away from the forward direction, the leveler is located on the center surface of the frame along the forward direction, the leveler is flexibly mounted on the frame by an elastic pre-tightening component, two sets of ridging scrapers are arranged symmetrically with respect to the center surface, the ridging scraper is located on the side of the leveler away from the center surface, and the cutter roller is located on the side of the ridging scraper away from the center surface.

[0005] Furthermore, the elastic preload assembly includes an adjusting shaft and an elastic element. The adjusting shaft is movably disposed on the center plane of the frame along the forward direction. One end of the elastic element is fixedly connected to the adjusting shaft, and the other end of the elastic element is connected to the leveler.

[0006] Furthermore, the elastic pretensioning assembly also includes an adjusting plate, an adjusting shaft with adjusting holes spaced apart along the axial direction, the adjusting plate being locked to the adjusting holes by a positioning pin, and one end of the elastic element abutting against the adjusting plate.

[0007] Furthermore, the adjusting shaft is rotatably connected to the frame via an adjusting sleeve.

[0008] Furthermore, the leveler includes a shaping plate, one end of which is hinged to the frame and the other end of which is hinged to an elastic element.

[0009] Furthermore, a shaping section is provided at the lower end of the shaping plate.

[0010] Furthermore, the shaping plate is tilted downwards from one end to the other, away from the forward direction.

[0011] Furthermore, the ridge scraper includes a column and a ridge scraper plate, with the column mounted on the frame and the ridge scraper plate mounted on the column.

[0012] Furthermore, the shape of the ridge scraper projected onto the central plane is arc-shaped, and the distance between the ridge scraper and the central plane increases sequentially from top to bottom.

[0013] Furthermore, a protective ridge board is provided on the side of the column facing away from the direction of travel.

[0014] The beneficial effects of this utility model are as follows: A ridging and shaping device for leveling operations has a symmetrically arranged scraper on each side of the cutter roller. During the rotary tillage and ridging operation, the soil clods are pushed and broken up into ridges by the scraper under the forced guidance of the scraper towards the center of the cutter roller's axis. A leveler is arranged behind the two scrapers. With the combined operation of the cutter roller and the leveler, the soil clods are further broken up and shaped into level ridges as the leveler obstructs soil flow and scrapes the ridges. The ridges exhibit excellent performance in terms of height, width, and flatness, which helps improve the sowing effect and performance of the ridging seeder. This ridging and shaping device for leveling operations uses a cutter roller, scraper, and automatic contour leveler in combination for rotary tillage and ridging operations. It has a simple structure and produces ridges with excellent performance in terms of height, width, and flatness, which helps improve the sowing effect and performance of the ridging seeder, thereby increasing planting yield and efficiency.
