[0036] In this example, a traction frame 1 connected to a tractor is provided at the front end of the main frame.

[0037] Instructions for use: It is mainly composed of a traction frame, a notched harrow group, a disc harrow group, a main frame, a leveling plate, a soil crushing roller group and a soil pressing roller group. Due to the large size of large-scale land preparation machines, it is not suitable to be shipped as a whole; all components are packed and shipped to the destination (site) and then assembled; in order to quickly and conveniently assemble the land preparation machine on site, the soil crushing roller and the soil pressing roller are assembled into an integral component for shipment during design, which is convenient for subsequent rapid assembly of the whole machine on site.

[0038] In order to facilitate operation and transportation, the two wings of the main frame are also equipped with notched harrows, disc harrows, leveling plate crushing rollers and soil pressing rollers. When not in operation or transportation, the two wings can be retracted and folded by hydraulic cylinders for easy traction and transportation. Due to the different moisture content of the leveled land, in order to prevent the soil from adhering to the notched harrow or disc harrow during turning over, affecting the operation efficiency and turning over effect, a scraper is installed on the inside of each notched harrow and disc harrow to prevent the soil from adhering to the notched harrow and disc harrow, and the notched harrow and disc harrow are arranged in reverse to achieve a better turning over effect. Each set of crushing rollers and soil pressing rollers are of stepped design, so that the places that the crushing rollers cannot cover are fully covered by the soil pressing rollers (the soil pressing rollers have the function of compacting the soil to keep it moist and crushing the soil), avoiding the existence of unbroken soil in the operation area that affects the operation effect. The main frame is provided with a wheel group for bearing the overall weight of the land preparation machine and being towed forward with the tractor.

[0039] This structure relies on tractor traction (no transmission shaft output) to drive the notched harrow, disc harrow, leveling plate, soil crushing roller, soil pressing roller and wheel group to move forward to complete the work needs; the soil crushing roller and soil pressing roller are arranged in a stepped manner to fully cover the working area; the two wings of the main frame are folded up for easier transportation; and because there is no power transmission output, the power consumption of power transmission is reduced, and the cost of land preparation is also reduced.

[0040] It should be noted that the notched harrow, disc harrow, flat soil plate crushing roller and soil pressing roller in this structure are all existing technical means, so the structure and installation position are not described in detail in this article. Figure 1 .

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
