[0014] The present invention provides an intelligent agricultural tillage and land preparation machine, which has the following beneficial effects: (1) In the present invention, when the roller rotates, the roller will drive the tilling shovel to rotate. When the tilling shovel rotates, the tilling shovel will come into contact with the soil. At this time, the tilling shovel will till the soil, which is beneficial to the planting and rooting of crops. When the rotating plate is out of contact with the discharge port, the fertilizer in the storage bin will fall into the soil through the discharge port. When the fertilizer falls into the soil, the fertilizer can help the growth of crops. When the tilling shovel is out of contact with the rotating plate, the rotating plate will continue to cover the discharge port under the elastic force of the torsion spring, which can effectively prevent too much fertilizer from spilling out and burning the crops.

[0015] (2) In the present invention, when the second long board moves downward, the second long board will drive the thick rod to move downward. When the thick rod moves downward, the thick rod can break up the harder and larger soil blocks. There are larger gaps between the larger soil blocks, and it is not easy for water to penetrate into the deep soil, which can effectively prevent the phenomenon of water shortage during the growth of crops. When the thin rod moves downward, the thin rod will contact the ground. At this time, the thin rod will crush the soil blocks broken by the thick rod again, which can ensure that the soil blocks are completely crushed, and can effectively improve the root development of crops.

[0016] (3) In the present invention, when there are stones on the ground, the stones will contact the long board three, and the stones will roll backward along the inclined surface of the long board three, which can effectively prevent the stones from appearing on the ground and affecting the crops. When the slide plate moves backward, the slide plate will drive the blade to move backward. When the blade moves backward, the blade can cut and remove the grass and straw extending to the right side of the grass inlet. When the whetstone moves upward, the whetstone can grind the blade, which can effectively ensure the sharpness of the blade. When the vertical blade continues to move upward, the vertical blade will be tangent to the horizontal board. At this time, the vertical blade will cut the longer grass and straw into segments, which can effectively prevent excessive weeds from affecting the growth of crops. After the weeds and straw are cut, they will decompose over time. When the weeds and straw decompose, they can release organic matter, which can effectively increase the organic matter content in the soil. BRIEF DESCRIPTION OF THE DRAWINGS
