Abstract

The invention discloses a variable-amplitude foldable land leveler for a dry land. The variable-amplitude foldable land leveler for the dry land comprises a traction frame, a machine frame, a land leveling shovel and a walking mechanism. The traction frame is connected with the machine frame. The land leveling shovel and the walking mechanism are arranged on the machine frame. The land leveling shovel comprises a main shovel blade, two auxiliary shovel blades and two variable-amplitude shovel blades. Each end of the main shovel blade is sequentially connected with one auxiliary shovel blade and one variable-amplitude shovel blade. The main shovel blade is hinged to the auxiliary shovel blades. A folding power mechanism is arranged between each auxiliary shovel blade and the corresponding variable-amplitude shovel blade and pushes the auxiliary shovel blade to conduct folding movement towards the front of a shoveling surface. Each folding power mechanism is located on the back side of the shoveling surface. Each folding power mechanism comprises a telescopic cylinder, wherein a cylinder block of the telescopic cylinder is hinged to the main shovel blade, and a telescopic rod of the telescopic cylinder is hinged to the corresponding auxiliary shovel blade. Each auxiliary shovel blade and the corresponding variable-amplitude shovel blade are connected through a detachable structure. The amplitude of the land leveling shovel of the land leveler can be adjusted, and therefore transportation is convenient.

Description

technical field [0001] The invention relates to an agricultural mechanical equipment, in particular to a variable width foldable dry land grader. Background technique [0002] Leveling the land is an important measure to build a stable and high-yield farmland with guaranteed income from drought and flood, and it is also a prerequisite for the development of dryland irrigation. If the field surface is uneven, it will be difficult to irrigate the high places with water, and the water in the low places will be too deep, and there will be phenomena such as soil running, water running, and fertilizer running. Therefore, the masses said: "Drilling a well without leveling the ground is tantamount to wasting effort." Whether the land is level or not has a great impact on the growth and yield of crops. The leveled land is conducive to irrigation, farming, saving land and labor, and is conducive to the production of crops. At present, the leveling shovels of dry land graders in my c...
