Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the utility model, and not restrictive of the full scope of the utility model. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.

Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. The embodiments described below do not limit the scope of the utility model described in the claims. Further, the entire contents of the configurations shown in the following embodiments are not limited to those necessary as a solution of the utility model described in the claims.

Referring to FIG. 1, an embodiment of the present invention provides a grader including a frame 1, a blade 2, and an adjustment mechanism. The frame 1 can be a frame structure or a skeleton structure formed by connecting sectional materials and the like through welding or threaded fasteners, and the frame 1 is used for being connected with power equipment so that the power equipment pulls the frame 1 to operate. Optionally, the power plant is a tractor. The blade 2 is rotatably connected to the frame 1, and the rotation axis of the blade 2 extends in the vertical direction. Here, the vertical direction means a vertical direction in a state where the motor grader is operating. The adjusting mechanism is used for adjusting the rotation angle of the scraper 2. When the land leveling machine is used, the frame 1 of the land leveling machine is connected with power equipment, the angle of the scraper 2 in the vertical direction is adjusted to a proper value through the adjusting mechanism, and the land leveling machine is driven to move through the power equipment to finish land leveling operation. So set up, can make the leveler be adapted to different work occasions through adjustment scraper blade 2 turned angle, direction of rotation to the scraper blade 2 of the equipment of strickleing off among the prior art has been solved and has been set up fixedly usually, the adjustment of being inconvenient, the inconvenient problem of use.

In some embodiments, the adjustment mechanism comprises a linear drive. One end of the linear driving device is hinged with the frame 1, and the other end is hinged with the scraper 2. The rotation of the scraper blade 2 is adjusted through the telescopic action of the linear driving device, the action is flexible and accurate, the operation is convenient, the leveling field has higher precision, and the device is suitable for constructing roadbeds and pavements, building side slopes and excavating side ditches.

In some embodiments, the number of linear drives is two. Two linear driving devices are distributed on two sides of the machine frame 1 in the advancing direction, one end of each linear driving device is hinged to the machine frame 1, and the other end of each linear driving device is hinged to the scraper 2. So set up, can improve the structural rigidity of leveler through setting up two linear drive device for in the running process of leveler, 2 rigidity of scraper blade are better, and are more stable, thereby make the levelling field have higher precision.

In some embodiments, the linear drive is a ram 3. The rotation angle of the scraper 2 along the rotation axis can be conveniently adjusted by controlling the telescopic length of the oil cylinder 3, so that different working requirements can be met.
