[0024] Refer to the attached Figure 1 The embodiment of the present application provides a land leveling machine, including a vehicle body, a plow and a connecting frame 1. The vehicle body and the plow are both existing structures. The connecting frame 1 is arranged between the vehicle body and the plow, and the connecting frame 1 is respectively hinged with multiple groups of front connecting arms 2 hinged with the plow and multiple groups of rear connecting arms 3 hinged with the vehicle body. At the same time, the connecting frame 1 is provided with moving wheels 4, so that the connecting frame 1 can move along with the land leveling machine. It is not difficult to find that by improving the rigid connection between the traditional vehicle body and the plow to a connecting frame 1 movably hinged with the vehicle body and the plow, when the plow encounters gravel during operation, the connecting frame 1 can alleviate the impact of the gravel on the plow and the vehicle body, thereby reducing the problem of breakage of the vehicle body and the plow due to the rigid connection.

[0025] Specifically:

[0026] like Figure 1As shown, the connecting frame 1 includes a load-bearing bottom beam 101 and a cantilever beam 102. The cantilever beam 102 is welded to the load-bearing bottom beam 101. Both ends of the load-bearing bottom beam 101 are counterweighted with all-terrain mobile wheels 4 to facilitate the completion of farming operations with the vehicle.

[0027] In the above description, the front connecting arm 2 includes a front first connecting arm 201, a front second connecting arm 202, and a front third connecting arm 203. The cantilever beam 102 and the load-bearing bottom beam 101 are provided with a front hinge seat 5 for pivotally connecting the front first connecting arm 201, the front second connecting arm 202, and the front third connecting arm 203, respectively. The front first connecting arm 201 is provided in the middle of the cantilever beam 102, the front second connecting arm 202 and the front third connecting arm 203 are provided on the load-bearing bottom beam 101, and the front second connecting arm 202 and the front third connecting arm 203 are symmetrically arranged with respect to the front first connecting arm 201. One end of the front first connecting arm 201, the front second connecting arm 202 and the front third connecting arm 203 are pivotally hinged to the connecting frame 1 through the front hinge seat 5. At the same time, front hinge seats for pivotally connecting the front first connecting arm 201, the front second connecting arm 202 and the front third connecting arm 203 are welded on the plowshare. The other ends of the front first connecting arm 201, the front second connecting arm 202 and the front third connecting arm 203 are pivotally hinged to the plowshare through the front hinge seat.

[0028] Alternatively, the rear connecting arm 3 includes a rear first connecting arm 301, a rear second connecting arm 302, and a rear third connecting arm 303. The cantilever beam 102 and the load-bearing bottom beam 101 are provided with a rear hinge seat 6 for pivotally connecting the rear first connecting arm 301, the rear second connecting arm 302, and the rear third connecting arm 303. The rear first connecting arm 301 is provided in the middle of the cantilever beam 102 and is located on opposite sides of the cantilever beam 102 as the front first connecting arm 201. The rear second connecting arm 302 and the rear third connecting arm 303 are provided on the load-bearing bottom beam 101, and the rear second connecting arm 302 and the rear third connecting arm 303 are symmetrical about the rear first connecting arm 301. In addition, the rear second connecting arm 302 and the rear third connecting arm 303 are located on the side of the load-bearing bottom beam 101 facing the vehicle body, and are located between the front second connecting arm 202 and the front third connecting arm 203 on the side of the load-bearing bottom beam 101 facing the plow, and the rear second connecting arm 302 and the rear third connecting arm 303 are located between the front second connecting arm 202 and the front third connecting arm 203, so that the front connecting arm 2 and the rear connecting arm 3 are staggered to avoid the impact force being hit and transmitted to one place, which causes concentrated force to damage the connecting frame 1.

[0029] In the above, one end of the rear first connecting arm 301, the rear second connecting arm 302 and the rear third connecting arm 303 are pivotally hinged to the connecting frame 1 through the rear hinge seat 6. At the same time, rear hinge seats are welded on the vehicle body for pivotally connecting the rear first connecting arm 301, the rear second connecting arm 302 and the rear third connecting arm 303 respectively. The other ends of the rear first connecting arm 301, the rear second connecting arm 302 and the rear third connecting arm 303 are pivotally hinged to the vehicle body through the rear hinge seat.

[0030] In summary, the embodiment of the present application provides a land leveling machine, in which a connecting frame is installed between the vehicle body and the plow through a movable hinge. When the plow collides with gravel during the plow operation, the movable hinged connecting frame can alleviate the impact of the gravel on the plow and the vehicle body, thereby reducing the occurrence of breakage between the plow and the vehicle body due to the rigid connection.

[0031] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
