Description

TECHNICAL FIELD

[0001] The utility model relates to a land preparation machine, in particular to a shunt type land preparation machine. BACKGROUND

[0002] With the progress of agricultural planting technology, large-scale planting and large agricultural machinery play an increasingly important role, especially land preparation machinery, which will have an important impact on the entire planting period.

[0003] At present, the land preparation machinery in large-scale planting generally uses a combined land preparation machine, which can complete soil crushing, leveling and pressing in one operation. However, in practice, due to different crops and different land conditions, the requirements for land preparation will also be different. However, large machinery like the combined land preparation machine has relatively fixed components for operation, such as the "combined land preparation machine" disclosed in CN2196845Y on May 17, 1995, which is characterized by a disc harrow blade group, a leveling tooth plate, and a soil crushing and pressing roller arranged in sequence on the frame. The leveling tooth plate is connected to the frame through a profiling mechanism, and the main function of the leveling plate is to level the ground. However, since the leveling mechanism on the frame is generally originally set, it completes the task as specified, such as pre-sowing leveling, post-harvest no-tillage land preparation, or re-cultivation land preparation. Once set, it is difficult to change. Due to different operations or different requirements for operations, the attached mechanisms will also be different.

[0004] Therefore, a land preparation machine that can conveniently replace operation components according to actual needs, especially a shunt type land preparation machine suitable for large traction vehicles, has emerged as the times require. SUMMARY
