Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-12, in order to solve the problem that most of the existing reseeding devices are no different from those used for sowing, and most of the devices are very large and destroy the already grown grass, the opening and closing components are used to operate only in a small area where reseeding is required, so as to avoid large-scale reclamation and soil turning to destroy the already grown grass, and at the same time, the opening and closing components are used in coordination with the covering components, and the opening and closing components are controlled to complete soil turning, sowing, and covering at one time without moving the device, and each time a fixed amount of sowing is sown in a trough, a small-scale operation of a fixed point is realized, so as to realize the reseeding of forage grass. The present invention provides a technical solution: a reseeding device for ecological restoration of forest and grass wetlands, including an outer frame 1, a seed box 2, and an inner frame 3, wherein the outer frame 1 is slidably connected to the inner frame 3, a seed box 2 is fixedly installed on the inner frame 3, grass seeds are placed in the seed box 2, an opening and closing component 4 is arranged under the seed box 2, the opening and closing component 4 controls the falling of the grass seeds, and a covering component 5 is arranged on the opening and closing component 4, and the covering component 5 is used for tilling and covering the grass seeds. The outer frame 1 is fixedly connected to one end of a plurality of support rods 101, and the other end of the support rod 101 is equipped with a universal wheel 102. The inner frame 3 is fixedly connected to one end of a plurality of inner frame support rods 301, and the other end of the inner frame support rods 301 is slidably connected to the outer frame 1, and one of the inner frame support rods 301 is fixedly connected to the output end of the cylinder, and the cylinder is fixed to the outer frame 1. In this application, electrical components such as motor cylinder push rods are all of existing models. When in use, move the device to the position to be reseeded, and then start the cylinder, the cylinder drives the inner frame support rod 301 to move downward, and the inner frame support rod 301 drives the inner frame 3 to move downward, so that the opening and closing component 4 and the soil covering component 5 move downward until the opening and closing component 4 touches the ground. At this time, start the opening and closing component 4 to open and start the soil covering component 5 to dig the soil. When the opening and closing component 4 is opened to the maximum, the grass seeds fall from the seed box 2 into the dug pit, and then close the opening and closing component 4, and the opening and closing component 4 drives the soil covering component 5 to cover the soil until the opening and closing component 4 is completely closed to complete the soil covering. At this time, the fixed-point reseeding at this location is completed, and the device is moved to the next position to be reseeded and the above operation is repeated.

[0027] In order to realize fixed-point sowing, an opening and closing component 4 is provided, which includes a plurality of arc-shaped pieces 401 and an opening and closing ring 405. The plurality of arc-shaped pieces 401 are assembled into a circle, and the lower end of the seed box 2 is contacted and connected thereto. Each arc-shaped piece 401 is fixedly connected to one end of a fixed shaft 402 and a swing shaft 403, the other end of the fixed shaft 402 is rotatably connected to the inner frame 3, the other end of the swing shaft 403 is rotatably connected to one end of an opening and closing rod 404, the other ends of the plurality of opening and closing rods 404 are rotatably connected to the opening and closing ring 405, and the opening and closing ring 405 is rotatably connected to the lower surface of the inner frame 3. When in use, the opening and closing ring 405 is rotated, and the opening and closing ring 405 pulls the multiple opening and closing rods 404 to move the opening and closing rods 404, and the opening and closing rods 404 drive the swing shaft 403 to move, and the swing shaft 403 drives the arc piece 401 to rotate around the fixed shaft 402 as the axis, so that the multiple arc pieces 401 are opened away from each other, and the lower end of the seed box 2 is opened for sowing; when sowing is completed, the opening and closing ring 405 is reversed to drive the arc piece 401 to close the lower end of the seed box 2.

[0028] In order to be able to sow seeds in a quantitative manner in the trough, a rotating ball 201 is hingedly connected in the seed box 2 by a torsion spring. A groove for accommodating seeds is provided on the rotating ball 201. The torsion spring ensures that the groove is always facing upward. A ball gear 202 is fixedly connected to both sides of the rotating ball 201 through an axis. The ball gear 202 is rotatably connected to the outside of the seed box 2. A ball ring 203 is provided under the ball gear 202. The ball ring 203 is provided with teeth that can mesh with the ball gear 202. The ball ring 203 is fixedly connected to one end of a plurality of ball ring support rods 204, and the other end of the ball ring support rod 204 is fixed on the opening and closing ring 405. When the opening and closing ring 405 drives the arc piece 401 to open, the opening and closing ring 405 drives the ball ring support rod 204 to move, and the ball ring support rod 204 drives the ball ring 203 to rotate. When the arc piece 401 is about to rotate to fully open, the teeth on the ball ring 203 begin to mesh with the ball gear 202, and the opening and closing ring 405 continues to rotate, the ball ring 203 drives the ball gear 202 to rotate, and the ball gear 202 drives the rotating ball 201 to reverse 180 degrees, sowing the grass seeds in the groove of the rotating ball 201 to the land below, and the torsion spring is deformed by force; when the opening and closing ring 405 is rotated to drive the arc piece 401 to close, the rotating ball 201 is reset under the joint action of the torsion spring and the ball gear 202, and the torsion spring prevents the rotating ball 201 from rotating by itself and scattering the grass seeds.

[0029] In order to facilitate soil digging and covering of grass seeds, a covering component 5 is provided, which includes a soil digging knife 501 and a covering knife 502. The soil digging knife 501 is arranged at a radial position close to the circle formed by the arc-shaped pieces 401, and the covering knife 502 is arranged at a circumferential position close to the circle formed by the arc-shaped pieces 401. A group of covering components 5 is provided on each arc-shaped piece 401. The soil digging knife 501 and the covering knife 502 are both slidably connected to the arc-shaped piece 401. The upper ends of the soil digging knife 501 and the covering knife 502 are respectively fixedly connected to a knife rack 503. The two knife racks 503 are arranged in parallel and are both slidably connected to the arc-shaped piece 401. The two knife racks 503 are meshed with the same knife gear 504, and the knife gear 504 is rotatably connected to the arc-shaped piece 401. A control mechanism is also provided on the knife rack 503. One end of a spring is fixedly connected to the lower portion of the knife rack 503, and the other end of the spring is fixed in the arc-shaped piece 401. When the opening and closing ring 405 drives the arc piece 401 to open, the opening and closing ring 405 drives the control mechanism to move the knife rack 503 connected to the earth-scraping knife 501 downward, thereby causing the knife gear 504 to rotate, and the covering knife 502 is driven by the knife rack 503 thereon to rise and retract, and the earth-scraping knife 501 is driven to rotate by the arc piece 401, thereby carrying out earth-scraping and digging pits; when the rotating opening and closing ring 405 drives the arc piece 401 to close, the opening and closing ring 405 drives the control mechanism to move the covering knife 502 downward, and the earth-scraping knife 501 rises and retracts. Since the covering knife 502 is located outside than the earth-scraping knife 501, the covering knife 502 pushes the soil just dug out back to cover the grass seeds during the closing process of the arc piece 401, thereby realizing the covering of the grass seeds; when use is finished, the earth-scraping knife 501 and the covering knife 502 are reset under the action of the spring.

[0030] In order to facilitate the control of the extension and retraction of the planing knife 501 and the covering knife 502, a control mechanism is provided, which includes a half gear 509. The upper end of each knife rack 503 is fixedly connected to a guide column 505, and the guide column 505 is always slidably connected to the guide rail 506. Each guide rail 506 is fixedly connected to one end of a guide rail connecting rod 507. The other ends of the two guide rail connecting rods 507 of the same covering assembly 5 are slidably connected to the same toggle baffle 510. The guide rail connecting rod 507 is fixedly connected to one end of a spring, and the other end of the spring is fixedly connected to the toggle baffle 510. The half gear 509 is hinged to the toggle baffle 510 through a torsion spring. The half gear 509 is symmetrically fixedly connected to one end of two toggle rods 508. The toggle rods 508 contact the guide rail connecting rod 507 connected to the same toggle baffle 510. The toggle baffle 510 is fixedly connected to the inner frame 3. Teeth are provided under the opening and closing ring 405 to engage with the half gear 509. When the opening and closing ring 405 does not rotate, the teeth on the opening and closing ring 405 have not yet meshed with the incomplete teeth on the half gear 509. When the opening and closing ring 405 starts to rotate, the teeth on the opening and closing ring 405 mesh with the half gear 509, and the opening and closing ring 405 drives the half gear 509 to rotate. At this time, the torsion spring begins to be stressed. Since the teeth on the half gear 509 are incomplete teeth, the half gear 509 can only be disengaged after rotating a certain angle. However, due to the action of the torsion spring, the teeth on the half gear 509 will mesh again, so that it continues to be stressed. During the process of rotating in one direction, 05 always maintains an angle, the lever 508 of the half gear 509 swings, one of the levers 508 presses down the guide rail connecting rod 507, the guide rail connecting rod 507 drives the guide rail 506 to be pressed down, the guide rail 506 drives the guide column 505 to be pressed down, and the guide column 505 drives the knife rack 503 to be pressed down; when the opening and closing ring 405 is reversed, the opening and closing ring 405 drives the half gear 509 to flip, at this time, the other knife rack 503 can be pressed down, and when the opening and closing ring 405 is reset, the half gear 509 returns to its original position under the action of the torsion spring.
