[0022] For example, Figures 1-2As shown, a width-adjustable land leveler is characterized in comprising a hanger 1 which is connected with an external traction machine such as a tractor to drive the whole land leveler to walk and level land. The hanger 1 is provided with a fixed blade 3 and two movable blades 2 which are parallel to the fixed blade 3, wherein the two movable blades 2 are arranged at the front side and the rear side of the fixed blade 3, and each movable blade 2 is aligned with the upper edge and the lower edge of the fixed blade 3. The two movable blades 2 are connected with a driving mechanism on the hanger 1 to move in the width direction of the fixed blade 3, thereby increasing the width of the land leveler (the width refers to the direction perpendicular to the advancing direction of the land leveler).

[0023] In order to balance and support the blades and cooperate with the traction machine to drive the blades to walk, a supporting wheel mechanism is arranged on the hanger 1 and located behind the fixed blade 3. Under the driving of the external traction machine, the supporting wheel mechanism supports the fixed blade 3 and the movable blades 2 to move, or supports the blades to lift up or fall down.

[0024] Further, in order to improve the stability of the movable blades 2 when moving in the width direction of the fixed blade 3 and ensure that the movable blades 2 move straight in the horizontal direction, a first guide cylinder 5 is arranged on the hanger 1 and arranged horizontally along the width direction of the fixed blade 3. In order not to interfere with the blades, the first guide cylinder 5 is arranged at the rear side of the fixed blade 3, and the two movable blades 2 are arranged at the front side of the fixed blade 3 and abut against the front side surface of the fixed blade 3. When moving, the two movable blades 2 always have an overlapping part with the fixed blade 3 in the front-rear direction. The two movable blades 2 are correspondingly connected with two first guide rods 6 which are correspondingly inserted into the first guide cylinder 5 from both ends of the first guide cylinder 5 and move along the first guide cylinder 5 under the driving of the driving mechanism.

[0025] Further, in order to reduce the friction between the movable blades 2 and the fixed blade 3 when moving, each movable blade 2 is provided with two rollers 4 which are arranged in an upper-lower interval. Each roller 4 abuts against the front side surface of the fixed blade 3, and the rollers 4 roll on the front side surface of the fixed blade 3 when the movable blades 2 move relative to the fixed blade 3.

[0026] Further, the movable scraping shovel 2 and the fixed scraping shovel 3 have the same structure, and each specifically comprises an upper scraping plate, a lower scraping plate and an intermediate connecting plate, the lower scraping plate is detachably connected to the upper scraping plate through the intermediate connecting plate, the strength of the lower scraping plate is higher than that of the upper scraping plate, for example, the lower scraping plate can be made of hard alloy steel, and the upper scraping plate can be made of alloy steel or ordinary stainless steel, the lower scraping plate has higher hardness and strength and can better withstand the impact strength of the underground soil and stone, thereby reducing the damage of the scraping shovel, and the above structure is also convenient for disassembling and replacing the lower scraping plate.

[0027] Further, the specific structure of the driving mechanism comprises two first telescopic cylinders 7, the first telescopic cylinders 7 can be oil cylinders, air cylinders or electric cylinders, and the two first telescopic cylinders 7 are arranged on the suspension frame 1 and correspondingly connected to the two movable scraping shovels 2.

[0028] Alternatively, the two first telescopic cylinders 7 can be replaced by a double-rod air cylinder or a double-rod oil cylinder.

[0029] Further, the supporting wheel mechanism comprises two traveling wheels 10, and the two traveling wheels 10 are symmetrically arranged on both sides of the vertical bisector of the fixed scraping shovel 3.

[0030] Further, in order to make the scraping shovel of the land leveler better balanced and supported by the traveling wheel 10 mechanism after being extended, a second guide cylinder 8 is further arranged on the suspension frame 1, the second guide cylinder 8 is parallel to the first guide cylinder 5, the two traveling wheels 10 are correspondingly connected to two second guide rods 9, the two second guide rods 9 are movably inserted into the second guide cylinder 8, and an extension driving member is arranged between the second guide cylinder 8 and the two second guide rods 9, and the extension driving member drives the two second guide rods 9 to slide in the second guide cylinder 8.

[0031] Further, the specific structure of the extension driving member comprises two second telescopic cylinders 11, and the two second telescopic cylinders 11 are correspondingly connected to the two second guide rods 9.

[0032] Alternatively, the two second telescopic cylinders 11 can also be replaced by a double-rod air cylinder or a double-rod oil cylinder or a double-rod electric cylinder.
