[0001] The present invention relates to the technical field of ecological restoration, and in particular to a method for efficiently restoring the ecological environment of a mining area. Background Art
[0002] Ecological restoration is a comprehensive approach to remediating polluted environments, guided by ecological principles and based on bioremediation. It combines various physical, chemical, and engineering measures to achieve optimal results and minimize costs through optimized combinations. The most direct methods of ecological restoration are grassland and afforestation. For example, patent application number CN202011040137.1 discloses an efficient ecological restoration method for mining areas.
[0003] After the seeds are sown, the existing repair method usually uses some heavier rollers to compact the soil with the seeds buried inside. However, the soil is easy to adhere to the rollers due to its relative moisture, which can easily affect the compaction effect of the rollers, making it impossible for the rollers to compact the soil with the seeds buried inside. In addition, the sowing effect of the existing repair method is general, and uneven sowing is prone to occur. Summary of the Invention

[0047] First, connect the agricultural machine to the agricultural vehicle through the two agricultural machine connecting rods on the sub-frame 101, so that the agricultural vehicle can carry the equipment to work, and then manually observe whether the arrow directions of the arrows pointing to arrow A and arrow B are pointing directly upward. If not, manually rotate the liquid medicine cylinder 7 and the grass seed cylinder 601 to adjust the arrows pointing to arrow B and arrow A to point directly upward. If the arrow directions of the arrows pointing to arrow A and arrow B point directly upward, it is convenient to explain that the grass seed inlet 602 and the liquid inlet 702 are respectively connected to the long tube 202 and When the short tube 201 is connected, the growth promoting liquid and grass seeds can be directly injected into the interior of the short tube 201 and the long tube 202 respectively, so that the growth promoting liquid and grass seeds enter the interior of the liquid medicine cylinder 7 and the grass seed cylinder 601 respectively through the short tube 201 and the long tube 202, thereby completing the feeding work. Then, the agricultural vehicle is used to drive the device to move along a suitable path. During the movement, the motor drives the shaft 3, the sleeve 301 and the seven sets of soil-opening pieces 302 to rotate, so that the soil is broken up so that the grass seeds can be mixed into the soil, thereby completing the feeding work. The soil is crushed, and in the process of the shaft 3 following the rotation of the motor, the shaft 3 will also drive the turntable 4 to rotate under the action of the pulley, so that the turntable 4 drives the crankshaft 401 to rotate, so that it drives one end of the connecting rod 402 to rotate along the circumferential trajectory of the turntable 4, so that the other end of the connecting rod 402 drives the slider 5 and the sliding rack 502 to move back and forth along the two guide rods, so that the sliding rack 502 drives the driving gear 6 and the grass seed barrel 601 to rotate clockwise and counterclockwise, so that the grass seeds inside it pass through a hole under the action of centrifugal force during rotation. The group sowing holes 603 are evenly thrown into the soil crushed by the seven groups of soil-breaking pieces 302, thereby completing the sowing work. At the same time, the driving gear 6 will drive the driven gear ring 701 and the medicine liquid cylinder 7 to rotate back and forth clockwise and counterclockwise, and the growth promoter inside will be evenly sprayed into the soil through a group of spraying holes 703, thereby completing the medicine spraying work. At the same time, the flattening piece 804 will move along the path of soil crushing, so that the flattening piece 804 will compact the soil mixed with grass seeds inside, so that the grass seeds can better contact with the soil and make the grass seeds easier to survive.
