The insertion assembly 7 includes a lower push rod frame 71 that rolls on the lower surface of the cam frame 65, and the bottom of the lower push rod frame 71 passes through the side frame 2 and is fixedly connected to an insertion tube 72. The upper hopper 3 and the insertion tube 72 are connected on both sides facing each other with an electromagnetic valve 73, and the inner end of the electromagnetic valve 73 is connected with a discharge telescopic tube 74. The grass seeds in the two groups of upper hoppers 3 that are shaking up and down are first discharged into the two insertion tubes 72 through the electromagnetic valve 73 and the discharge telescopic tube 74 to complete the feeding work before sowing the grass seeds. The insertion tube 72 is fixedly connected with a limit plate 75, and the two sides of the crossbeam frame 1 close to the side frame 2 are fixedly connected with The inner cavity of the limiting cylinder 76 is slidably connected with a T-shaped slide bar 77 fixedly matched with the limiting plate 75, and the outer surface of the T-shaped slide bar 77 is sleeved with a lower return spring 78 fixedly matched with the limiting cylinder 76.

[0027] like Figure 14-15As shown, before sowing grass seeds, in order to allow the grass seeds to survive better, the soil needs to be loosened mostly by hand, and it is not possible to carry out continuous operation with loosening measures when sowing grass seeds, resulting in low efficiency of sowing grass seeds. It is necessary to purchase loosening equipment separately, which increases its cost. A loosening assembly 10 is provided on the front side of the crossbeam frame 1, and the loosening assembly 10 includes a short bevel gear frame 101 meshed with the other side of the driving bevel gear 62 close to the driven bevel gear 63, the other end of the short bevel gear frame 101 is meshed with a main bevel gear 102, and the inner cavity of the main bevel gear 102 is fixedly connected to a long bevel gear frame 103 that rotates with the crossbeam frame 1, and both sides of the long bevel gear frame 103 are meshed with secondary bevel gears 104, and the driving bevel gear 62 drives the main bevel gear 102 to rotate through the short bevel gear frame 101 The main bevel gear 102 drives the two sets of sub-bevel gears 104 to rotate through the long bevel gear frame 103, and the inner cavity of the sub-bevel gear 104 is fixedly connected with a mounting cylinder 105 which rotates with the crossbeam frame 1, and the inner cavity of the mounting cylinder 105 is embedded with an electric push rod 106, and the piston rod of the electric push rod 106 penetrates the mounting cylinder 105 and is fixedly connected with a loosening frame 107, and the bottom of the loosening frame 107 is fixedly connected with a loosening head 108, firstly, the two electric push rods 106 are used to adjust the depth of the two sets of loosening frames 107 and the loosening head 108, and then the two sets of sub-bevel gears 104 drive the two sets of loosening frames 107 and the loosening heads 108 adjusted in place to rotate through the two sets of mounting cylinders 105, so as to loosen the soil in the area ahead of the grass seed sowing, and further improve the survival rate of the grass seeds.

[0028] The working principle of a grass seeding device for ecological restoration is as follows: first, the solar panel 18 provides power supply to the electrical components, and the two sets of double-row wheels 4 cooperate in movement. Then, the traction equipment is driven through the traction frame 5 to drive the crossbeam frame 1 and the side frame 2 to move forward as a whole. At the same time, the two electric push rods 106 are controlled to start and drive the two sets of loosening frames 107 and the loosening head 108 to move down to a predetermined depth in the soil, and then the servo motor 61 is controlled to start, and the servo motor 61 drives the driving bevel gear 62 to rotate, and the driving bevel gear 62 drives the short bevel gear frame 101 As it rotates, the gear at the other end of the short bevel gear frame 101 drives the main bevel gear 102 to rotate, and the main bevel gear 102 drives the long bevel gear frame 103 to rotate accordingly, and the gears at both ends of the long bevel gear frame 103 drive the two sets of auxiliary bevel gears 104 to rotate, and the two sets of auxiliary bevel gears 104 drive the two sets of loosening frames 107 and loosening heads 108 whose depths are adjusted to the right position through the electric push rods 106 in the two sets of mounting tubes 105 to rotate accordingly, and the two sets of loosening frames 107 and loosening heads 108 in the rotating state break and loosen the soil area in front of the grass seed sowing; At the same time, the driving bevel gear 62 drives the rotating rod 64 on the driven bevel gear 63 to rotate accordingly, and the rotating rod 64 drives the two groups of cam frames 65 to rotate synchronously. The two groups of cam frames 65 drive the two upper push rod frames 66 to perform reciprocating lifting and lowering movements, and perform reciprocating compression and reset springs 67. Then, the two upper push rod frames 66 that reciprocate and lift drive the two groups of flow equalizing plates 68 to move in the two groups of upper hoppers 3, and perform reciprocating lifting and lowering shaking on the grass seeds pre-poured in the two groups of upper hoppers 3, so that the grass seeds in the two groups of upper hoppers 3 pass through the two groups of flow equalizing plates 68 that reciprocate and lift in an orderly manner. The material evenly falls, and after being discharged from the two sets of material guide seats 11 through the opened electromagnetic valve 73 into the material discharge telescopic tube 74, it falls into the inner cavity of the two sets of interpenetrating tubes 72. At the same time, the two sets of cam frames 65 in the synchronous rotation state drive the two lower push rod frames 71 to perform reciprocating lifting and lowering movements. The two lower push rod frames 71 drive the two sets of interpenetrating tubes 72 to intersect up and down, and drive the T-shaped slide bar 77 to reciprocate and slide in the limiting tube 76, and reciprocate and compress the lower return spring 78 and perform elastic reset actions. The two sets of limit plates 75 then limit the depth of the two sets of interpenetrating tubes 72 inserted into the soil. When the two sets of insertion tubes 72 are inserted into the soil, the soil-prying heads 87 on the outer sides of the blocking covers 85 on the two sets of insertion tubes 72 are squeezed by the soil, generating an upward reverse thrust, and the limiting slide grooves 83 and the limiting slide bars 84 play a sliding limit role in the blocking covers 85. At the same time, under the action of the reverse thrust, the blocking covers 85 are forced to slide upward in the storage chamber 82 through the soil-prying heads 87, and leave the sowing window 81 area, making it open, and the upward sliding blocking covers 85 drive the auxiliary springs 86 to squeeze, so that the grass seeds that fall into the inner cavities of the two sets of insertion tubes 72 are After the two groups of guide racks 12 guide the materials to the sowing window 81 and the sowing hole 13, and then reach the soil through the opened sowing window 81 and the sowing hole 13, the two groups of interpenetrating tubes 72 are separated from the soil to the surface under the elastic restoring force of the lower restoring spring 78. At this time, the soil-moving head 87 on the outer side of the blocking cover 85 loses the reverse thrust generated by the soil, and under the elastic restoring force of the auxiliary spring 86, the blocking cover 85 is forced to reset downward in the storage chamber 82, and the sowing window 81 is re-blocked to prevent the grass seeds in the two groups of interpenetrating tubes 72 from falling to the surface. Next, the servo motor 61 drives the driven bevel gear 63 to rotate by driving the bevel gear 62, while the driving bevel gear 62 also drives the differential bevel gear 91 to rotate accordingly, and the differential bevel gear 91 drives the reciprocating screw rod 92 to rotate, and the T-shaped slide rail 14 and the T-shaped slide bar 15 play the role of sliding support for the double-sided toothed plate 94. The reciprocating screw rod 92 drives the double-sided toothed plate 94 on the long screw rod sleeve 93 to move back and forth horizontally, and the double-sided toothed plate 94 drives the two sets of transfer circular gears 95 to reciprocate outward expansion and inward contraction. The two sets of arc-shaped slide grooves 16 and the limit slider 17 play the role of sliding limit for the two sets of swing arm frames 96. The two sets of transfer circular gears 95 drive the combing tooth frames 97 on the two sets of swing arm frames 96 to expand outward and contract inward, combing and covering the soil in the area after interlaced planting to prevent grass seeds from being exposed to the surface.

[0029] It should be noted that the specific models and specifications of the servo motor 61 and the electric push rod 106 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.

[0030] The power supply circuits of the servo motor 61 and the electric push rod 106 are clear to those skilled in the art and will not be described in detail herein.
