A fixed plate is fixedly mounted on the bottom surface of the mounting plate. A pressure roller is rotatably mounted on the fixed plate. A land reclamation mechanism and a planting and irrigation mechanism are set on the mounting plate. A land leveling mechanism is set on the planting and irrigation mechanism. A fixed handle is fixedly mounted on the top of the mounting plate. The land reclamation mechanism includes a hydraulic rod, which is fixedly mounted on the mounting plate. The bottom end of the hydraulic rod is fixedly connected to a fixed frame. The top middle part of the fixed frame is fixedly mounted to the hydraulic rod. The central axis of the fixed frame and the central axis of the mounting plate are located on the same vertical center line. The side end of the fixed frame is fixedly connected to the first motor, and the output end of the first motor is fixedly connected to the reciprocating lead screw. The reciprocating lead screw is rotatably installed in the fixed frame. A sliding block is provided on the reciprocating lead screw. The reciprocating lead screw and the slider are threadedly engaged. The sliding block is limited and slidably installed in the fixed frame. The bottom end of the sliding block is fixedly installed to the connecting plate. The bottom end face of the connecting plate is fixedly connected to the first tillage blade. The reciprocating lead screw is connected to the middle part of the sliding block. The sliding block is fixedly set in the top middle part of the connecting plate. The first tillage blade is evenly distributed on the bottom end face of the connecting plate. The first tillage blade is in the shape of an isosceles trapezoid.

[0003] While existing technology utilizes a reciprocating screw to drive a connecting plate on a sliding block for convenient and stable reciprocating motion, thereby enabling each first tillage blade to reciprocate stably within the land, thus facilitating convenient and stable tillage and loosening of the soil in abandoned mines, and using the pushing action of the inclined surface at the end of the second tillage blade to push the loosened soil to both sides so that seeds can enter the soil; however, existing technology does not fully till the soil, which is detrimental to the survival rate of plant seeds. Moreover, different seeds require different planting densities and depths, and existing technology affects the later growth quality of vegetation. Summary of the Invention

[0031] like Figures 1-9 The diagram shows a conveyor seeder for mine greening restoration, comprising a support mechanism and four lifting mechanisms. The support mechanism includes a support frame 11 and four sets of rollers 13, which are symmetrically rotatably mounted on the wheel frames 111 of the support frame 11. The four lifting mechanisms are symmetrically arranged on the rectangular plate 112 of the support frame 11. Each lifting mechanism includes a drive gear 31 and a T-shaped frame 32. The drive gear 31 is rotatably mounted on the rectangular plate 112, and a protruding post 33 is slidably mounted on the adjusting groove 311 of the drive gear 31. The T-shaped frame 32 is longitudinally slidably mounted on the rectangular plate 112, and the protruding post 33 is slidably mounted on the hollow frame 321 of the T-shaped frame 32. Two sets of lifting mechanisms are symmetrically arranged. A soil loosening mechanism 2 is rotatably mounted on the T-shaped frame 32 of the structure. The position of the adjusting column 33 on the adjusting groove 311 is adjusted to change the soil loosening depth of the soil loosening mechanism 2. A seed feeding mechanism is set above the support frame 11. The seed feeding mechanism includes a seed box 61 and a seed distributing roller 64. The seed distributing box 62 at the bottom of the seed box 61 is fixedly mounted on the support frame 11. The seed distributing roller 64 is rotatably mounted inside the seed distributing box 62. Multiple trapezoidal grooves 641 are evenly arranged on the seed distributing roller 64. The trapezoidal grooves 641 correspond one-to-one with the rectangular holes 621 on the seed distributing box 62. A baffle 63 is set above each group of rectangular holes 621. The baffle 63 adjusts the number of seeds falling into the trapezoidal groove 641.

[0032] like Figure 1-4As shown, the support mechanism includes a support frame 11, a water tank 12, rollers 13, and a transmission assembly 14. Two pairs of wheel frames 111 are arranged below the support frame 11. There are two pairs of rollers 13, one pair corresponding to one pair of wheel frames 111. Each pair of rollers 13 includes two sets of rollers 13, and all four sets of rollers 13 rotate in the same direction. The rollers 13 are rotatably mounted on the wheel frames 111. The water tank 12 is located above the support frame 11, and multiple sets of nozzles 121 are arranged below the water tank 12. Water from the water tank 12 is sprayed onto the soil to be restored through the nozzles 121, facilitating soil loosening and seed germination. Two sets of rectangular plates 112 are symmetrically arranged on the wheel frames 111. The transmission assembly... There are two sets of components 14. The two sets of transmission components 14 are symmetrically arranged on both sides of the support frame 11. The transmission components 14 are located between the rectangular plate 112 and the roller 13 on the same side. The transmission components 14 include two sets of pulleys 141 and belts 142. One set of pulleys 141 is rotatably mounted on the rectangular plate 112 and coaxially connected to the drive gear 31. The other set of pulleys 141 is coaxially fixedly mounted with the roller 13 on the same side. The belt 142 is arranged on the two sets of pulleys 141. When the roller 13 rotates, it drives the pulley 141 fixedly mounted with it to rotate. Under the transmission action of the belt 142, it drives the other set of pulleys 141 to rotate.

[0033] like Figure 1 , Figure 4 , Figure 6 , Figure 7 , Figure 8As shown, there are four sets of lifting mechanisms, symmetrically arranged on rectangular plates 112. Each rectangular plate 112 has two sets of lifting mechanisms. Each lifting mechanism includes a drive gear 31, a T-shaped frame 32, a protruding column 33, and a limiting component 34. The drive gear 31 is rotatably mounted on the rectangular plate 112. The two sets of drive gears 31 on the same side of the rectangular plate 112 mesh with each other, meaning the rotation directions of the two sets of drive gears 31 on the same side are opposite. A pulley 141 on the rectangular plate 112 is fixedly mounted to one of the drive gears 31. When the pulley 141 on the rectangular plate 112 rotates, it drives the drive gear 31 fixed to it to rotate. The frame 32 is longitudinally slidably mounted on the rectangular plate 112. There are two sets of soil loosening mechanisms 2, with both ends rotatably mounted on two symmetrical sets of T-shaped frames 32. The drive gear 31 is provided with an adjustment groove 311, and multiple sets of limiting holes 312 are symmetrically arranged on the adjustment groove 311. A hollow frame 321 is provided on the T-shaped frame 32. A protruding column 33 is radially slidably mounted on the adjustment groove 311 and on the hollow frame 321 of the T-shaped frame 32. A limiting component 34 is located between the protruding column 33 and the drive gear 31. The limiting component 34 includes two sets of limiting plates 341 and a limiting spring 343. A fixed mounting plate 341 is installed on the limiting plate 341. A limiting post 342 is installed, and a limiting plate 341 is symmetrically slidably mounted inside a protrusion 33 via the limiting post 342. The protrusion 33 is slidably mounted on an adjusting groove 311 of the drive gear 31. A limiting spring 343 is disposed between two sets of limiting plates 341. Multiple sets of limiting holes 312 are symmetrically arranged on the adjusting groove 311. The limiting post 342 contacts and engages with the limiting holes 312, pressing the two sets of limiting plates 341. The two sets of limiting plates 341 move towards each other, compressing the limiting spring 343, disengaging the limiting post 342 from the limiting holes 312, adjusting the position of the protrusion 33 on the drive gear 31, and changing the axis of the protrusion 33 and the drive gear 31. The distance is adjusted by changing the lifting height of the T-shaped frame 32, thereby changing the soil turning depth of the loosening mechanism 2. The loosening mechanism 2 includes a rotating shaft with multiple sets of rotary tillage wheels 21. The rotary tillage wheels 21 of the two sets of loosening mechanisms 2 are arranged alternately. When the two sets of loosening mechanisms 2 rotate, they drive the rotary tillage wheels 21 to rotate. The alternate arrangement of the rotary tillage wheels 21 on the two sets of loosening mechanisms 2 improves the quality of soil loosening and makes the soil softer. The T-shaped frame 32 on the rectangular plate 112 on the same side moves in opposite directions. That is, when one set of loosening mechanisms 2 is at its highest point, the other set of loosening mechanisms 2 is at its lowest point. The two sets of loosening mechanisms 2 loosen the soil alternately, improving the quality of soil loosening.

[0034] like Figure 1 , Figure 4 , Figure 5As shown, a set of lifting mechanisms corresponds to a set of speed-changing mechanisms. The speed-changing mechanisms are located between the drive gear 31 and the T-shaped frame 32. The speed-changing mechanisms include a transmission gear 41, a speed-changing gear 42, a connecting rod 43, and a rocker arm 44. The rocker arm 44 is rotatably connected between the transmission gear 41 and the drive gear 31. The speed-changing gear 42 is rotatably mounted on the bottom of the T-shaped frame 32 and is fixedly mounted to the soil loosening mechanism 2. The connecting rod 43 is rotatably connected between the transmission gear 41 and the speed-changing gear 42. The transmission gear 41 meshes with the speed-changing gear 42 and the drive gear 31 respectively. When the drive gear 31 rotates, it drives the transmission gear 41 to rotate. The transmission gear 41 drives the speed-changing gear 42 to rotate. The speed-changing gear 42 drives the soil loosening mechanism 2 to rotate, thereby increasing the speed of the soil loosening mechanism 2. During this process, the rocker arm 44 and the connecting rod 43 swing.

[0035] like Figure 1 , Figure 5 , Figure 9As shown, the seed delivery mechanism is mounted on the support frame 11. The mechanism includes a seed box 61, a seed sorting box 62, a baffle 63, a sorting roller 64, an adjusting component 65, and a power source 66. The seed sorting box 62 is fixedly mounted on the support frame 11, and the seed box 61 is fixedly mounted above the seed sorting box 62. The seed sorting box 62 has multiple sets of rectangular holes 621, each set of rectangular holes 621 corresponding to a set of baffles 63. The baffles 63 are slidably mounted on the slide grooves 622 of the seed sorting box 62. The sorting roller 64 is rotatably mounted inside the seed sorting box 62. The power source 66 is fixedly mounted on the support frame 11. The output shaft is fixedly installed with the seeding roller 64. The power source 66 drives the seeding roller 64 to rotate. Multiple trapezoidal grooves 641 are evenly arranged on the seeding roller 64, each corresponding to a rectangular hole 621 on the seed box 62. When the seeding roller 64 rotates, seeds in the seed box 61 fall into the trapezoidal grooves 641 through the rectangular holes 621. A set of baffles 63 corresponds to a set of adjusting components 65. The adjusting components 65 are located between the elongated plate 623 and the baffles 63 in the seed box 62. The adjusting components 65 include an adjusting ball 651, an adjusting column 652, and an adjusting spring 653. Adjusting ball 651 and adjusting column 652 are fixedly installed. Adjusting column 652 is slidably installed on long strip plate 623. Adjusting spring 653 is disposed between adjusting ball 651 and long strip plate 623, and adjusting spring 653 is slidably installed on adjusting column 652. Baffle 63 has multiple sets of adjusting holes 631 at its bottom. Adjusting ball 651 contacts and engages with adjusting holes 631. Pulling baffle 63 causes it to slide on the groove 622 of the sorting box 62, breaking the contact between adjusting hole 631 and adjusting ball 651. Adjusting ball 651 drives adjusting column 652 to move away from adjusting hole 631. 653 is compressed until the baffle 63 slides to the target position, disconnecting the force applied to the baffle 63. Under the elastic action of the adjusting spring 653, the adjusting spring 653 drives the adjusting ball 651 and the adjusting column 652 to move closer to the adjusting hole 631 until the adjusting ball 651 continues to contact the adjusting hole 631, restricting the position of the baffle 63. This process changes the size of the connection between the rectangular hole 621 and the seeding roller 64, thereby changing the number of seeds falling into the trapezoidal groove 641 in the seed box 61 according to the planting characteristics of different seeds, thus changing the sowing density and better adapting to the growth of vegetation.

[0036] like Figure 1 , Figure 5As shown, a set of rectangular holes 621 corresponds to a set of sowing mechanisms. The sowing mechanisms are located at the bottom of the seed box 62. The sowing mechanisms include a receiving pipe 51, a telescopic pipe 52, and a plow head 53. The receiving pipe 51 is fixedly installed at the bottom of the seed box 62 and is located below the support frame 11. The receiving pipe 51 corresponds to the trapezoidal groove 641 on the seed roller 64. The telescopic pipe 52 is fixedly installed below the receiving pipe 51, and the plow head 53 is fixedly installed at the bottom of the telescopic pipe 52. The planting depth of the seeds is determined according to the characteristics of the seeds, and the length of the telescopic pipe 52 is adjusted according to the planting depth. The length of the telescopic pipe 52 is adjusted according to the sowing needs before use so that the seeds in the trapezoidal groove 641 enter the telescopic pipe 52 through the receiving pipe 51. The plow head 53 automatically plows the soil during the movement of the seeder, allowing the seeds to enter the soil.

[0037] Working principle: Based on the characteristics of the seeds of the vegetation to be planted, the depth of soil loosening and sowing is determined, thereby improving the survival rate of vegetation.

[0038] Based on the characteristics of the seeds, the planting depth is determined, and the length of the telescopic tube 52 is adjusted according to the planting depth so that the seeds in the trapezoidal groove 641 enter the telescopic tube 52 through the receiving tube 51. The plow head 53 then pries open the soil to facilitate the seeds entering the soil.

[0039] Adjusting the soil loosening depth of the loosening mechanism 2, the two sets of limiting plates 341 are squeezed and moved towards each other. The limiting spring 343 is compressed, the engagement between the limiting post 342 and the limiting hole 312 is broken, the position of the protrusion 33 on the drive gear 31 is adjusted, the distance between the protrusion 33 and the axis of the drive gear 31 is changed, the lifting height of the T-shaped frame 32 is changed, thereby changing the soil turning depth of the loosening mechanism 2.

[0040] Connect the support frame 11 to the rear of the tractor, open the nozzle 121 on the water tank 12, and spray water from the water tank 12 onto the soil, facilitating the loosening mechanism 2 to loosen the soil while maintaining soil moisture and improving seed survival rate. The tractor drives the support frame 11 to move, causing the roller 13 to rotate. The rotation of the roller 13 drives the pulley 141 fixedly mounted thereto to rotate. Under the transmission action of the belt 142, the pulley 141 on the rectangular plate 112 rotates, thereby driving the drive gear 31 fixedly mounted thereto to rotate. The rotation of the drive gear 31, in turn, drives the meshing drive gear 31 to rotate. The two sets of drive gears 31 on the same side rotate in opposite directions. When the drive gear 31 rotates, it drives the transmission gear 41 to rotate. The transmission gear 41 drives the speed change gear 42 to rotate. The speed change gear 42 drives the soil loosening mechanism 2 to rotate, thereby increasing the speed of the soil loosening mechanism 2. During this process, the rocker arm 44 and the connecting rod 43 swing. The drive gear 31 drives the T-shaped frame 32 to move longitudinally through the convex column 33. The T-shaped frame 32 on the rectangular plate 112 on the same side moves in opposite directions. That is, when one set of soil loosening mechanism 2 is at its highest point, the other set of soil loosening mechanism 2 is at its lowest point. The two sets of soil loosening mechanism 2 alternately loosen the soil, which improves the quality of soil loosening.

[0041] Based on the characteristics of the seeds, adjust the sowing density, pull the baffle 63, and the baffle 63 slides on the groove 622 of the seed box 62, disconnecting the contact between the adjusting hole 631 and the adjusting ball 651. The adjusting ball 651 drives the adjusting column 652 to move away from the adjusting hole 631, compressing the adjusting spring 653 until the baffle 63 slides to the target position, disconnecting the force applied to the baffle 63. Under the elastic action of the adjusting spring 653, the adjusting spring 653 drives the adjusting ball 651 and the adjusting column 652 to move closer to the adjusting hole 631 until the adjusting ball 651 and the adjusting column 652 are in contact. The joint hole 631 continues to contact, restricting the position of the baffle 63. This process changes the size of the connection between the rectangular hole 621 and the seeding roller 64, thereby changing the number of seeds falling into the trapezoidal groove 641 from the seed box 61 according to the planting characteristics of different seeds. The power source 66 is started. The power source 66 can be a motor. The power source 66 drives the seeding roller 64 to rotate. The seeds in the seed box 61 fall into the trapezoidal groove 641 through the rectangular hole 621. They are transported through the trapezoidal groove 641 and fall into the receiving pipe 51. The plow head 53 plows the soil and the seeds enter the soil.

[0042] The tractor drives the support frame 11 to move. During the sowing process, the support frame 11 vibrates, which in turn causes the seed box 61 to vibrate, preventing the seeds in the seed box 61 from clogging the rectangular hole 621 and ensuring the smooth progress of sowing.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
