The utility model relates to the technical field of agricultural farm tools, in particular to a land leveler.

Background

The land leveler is one kind of agricultural machine for cultivating dry land and is used mainly in leveling and loosening soil in the surface layer of dry land to facilitate planting crop. The conventional land leveler generally uses a straight scraping plate, when the scraping plate scrapes more soil, the soil can be accumulated in front of the scraping plate and not scattered, the tractor also increases the tire slip due to the resistance, at the moment, the angle of the scraping plate needs to be changed, the soil is scraped again after crossing a soil collection pile, the efficiency is low, and the energy consumption is high. Secondly, the scraping plate of the land leveler is wider, and a folding scraping plate is needed to be manufactured, but the synchronism of the scraping plate after being unfolded is poor, so that the land leveling effect is affected.

At present, the Chinese patent with the authority of CN209134746 discloses a dry farmland laser land leveller, which comprises a frame, wherein a connecting arm used for being connected with a tractor and a land wheel assembly used for walking are arranged on the frame, a cutter rest is also rotationally connected on the frame, a land leveller is arranged on one side of the cutter rest, a cutter handle is arranged on the other side of the cutter rest, a first hydraulic cylinder is rotationally connected on the frame, and a piston rod of the first hydraulic cylinder is rotationally connected with the cutter handle; the stand is provided with a vertical rod, and the vertical rod is provided with a laser receiver. The above patent still does not solve the problem that the efficiency of the grader becomes low as the amount of soil to be scraped becomes large and the mobility of the soil to be scraped becomes poor.

Therefore, it is a problem that needs to be solved by those skilled in the art how to provide a grader that does not cause the efficiency of the grader to be lowered due to the accumulation of scrapers.
