Description

Technical Field

[0001] The utility model relates to the technical field of scraping mechanisms, and more specifically, to a scraping mechanism for a paddy field satellite leveler. Background Art

[0002] Land leveling is a very important task in paddy field cultivation, as it directly affects rice planting quality, irrigation efficiency, and yield. The paddy field satellite land leveler is a mechanical device specifically designed for paddy field land leveling operations. It incorporates satellite positioning technology to facilitate accurate determination of the land leveler's three-dimensional position in the paddy field. The scraping mechanism of the paddy field satellite land leveler is located on the rear side of the tractor and is used to scrape soil and smooth the paddy field surface.

[0003] Most existing satellite land levelers are used for dry land and cannot be used directly to level paddy fields. If used to level paddy fields, the water in the paddy fields needs to be drained first, and then the land leveler is used to level the paddy fields. This is not only time-consuming and labor-intensive, but also wastes water resources. There is an urgent need for a scraping mechanism for a paddy field satellite land leveler that can directly level the land in the paddy fields.

[0004] Chinese patent application number CN202120802126.6 discloses a scraping mechanism for a paddy field satellite leveler, comprising a floating member, a scraping blade, and a scraping blade height adjustment device connected between the floating member and the scraping blade. This scraping mechanism can level the ground directly in the paddy field, eliminating the need to drain the paddy field. This simplifies operation, reduces work time, and improves leveling efficiency.

[0005] However, it can be seen from the drawings in the specification that if the paddy field soil is only leveled by a horizontal scraper, the excess soil will gather at the same position, and the potholes at the same horizontal position cannot be filled, resulting in uneven leveling effect and affecting the leveling effect.
