[0036] A forest and grass ecological restoration device includes a mounting frame 101 and a mounting plate 102, wherein the mounting plate 102 is fixedly mounted above the mounting frame 101, and a rotating seat 112 is fixedly connected below the mounting frame 101, and a wheel axle 103 is installed below the mounting frame 101 through the rotating seat 112 for horizontal rotation, and wheels 104 are fixedly installed at both ends of the wheel axle 103, and the wheels 104 are used to assist the movement of the mounting frame 101, and a driving gear 105 is fixedly arranged in the middle of the wheel axle 103, and the driving gear 105 is arranged through the mounting plate 102, and a blower housing 106 is fixedly connected to the upper surface of the mounting plate 102, and a blower shaft 108 is rotatably installed inside the blower housing 106, and the blower shaft 108 is located at the blower housing 106.

[0037] A bearing is provided between the axle 103 and the rotating seat 112 to reduce the rotational friction resistance between the axle 103 and the rotating seat 112. If necessary, a bearing is also provided at the connection between the axle 103 and the gear box 201 to reduce the rotational friction resistance.

[0038] The bottom of the seed slot 110 is conical, which is conducive to the seeds inside it to gather at the bottom and flow out;

[0039] The rotation of the wheel 104 is used to drive the rotation of the blower turbine 109, so that when the wheel 104 rotates faster, the blower turbine 109 also rotates faster, so the wind force generated is greater, and the vehicle speed is proportional to the wind force for sowing seeds, without the need to manually adjust the ratio of vehicle speed to seed sowing efficiency;

[0040] The present invention connects the mounting frame 101 to the rear of the driving vehicle through the connecting frame 701, and utilizes the wheel 104 to rotate and drive the blower turbine 109 to generate wind force inside the blower housing 106, so that the grass seeds dropped from the seed slot 110 can be sprayed out through the soft air guide 401 for long-distance sowing. At the same time, the rotation of the wheel 104 can also be used to drive the eccentric turntable 507 to drive the seed spreading port 402 to swing, thereby further increasing the sowing area, greatly improving the sowing efficiency and sowing area of ​​the grass seeds, and having a good use effect.

[0041] Furthermore, a gear box 201 is vertically provided in the middle of the mounting plate 102, and the gear box 201 is used to protect the driving gear 105 and the blower gear 107. The wheel axle 103 and the blower shaft 108 are both rotatably connected to the gear box 201, and the outer wall of the gear box 201 is fixedly connected to the mounting plate 102, and the blower housing 106 is fixedly connected to the outer wall of the gear box 201. The gear box 201 is located above the mounting plate 102 and is rotatably installed with a speed change shaft 202, and the speed change shaft 202 is located in the gear box 201. A first speed gear 203 is fixedly installed inside 201, a second speed gear 204 is fixedly arranged on one side of the first speed gear 203, the first speed gear 203 and the second speed gear 204 are coaxially arranged, the diameter of the first speed gear 203 is larger than the diameter of the second speed gear 204, the first speed gear 203 is meshed with the driving gear 105, the second speed gear 204 is meshed with the blower gear 107, and the first speed gear 203 and the second speed gear 204 are used to increase the rotation speed of the blower gear 107;

[0042] The first speed gear 203 and the second speed gear 204 have different diameters and are coaxial. The first speed gear 203 and the driving gear 105 have the same diameter. The second speed gear 204 and the blower gear 107 have the same diameter. The larger driving gear 105 can increase the angular velocity and linear velocity of the second speed gear 204 when driving the smaller second speed gear 204, thereby achieving the first increase in rotation speed. Since the second speed gear 204 is coaxial with the first speed gear 203, the angular velocities of the two are The first speed gear 203 has the same linear speed and a faster linear speed. When driving the smaller blower gear 107, the first speed gear 203 can increase the angular speed and linear speed of the blower gear 107, thereby achieving a second increase in rotation speed. Therefore, the blower turbine 109 coaxial with the blower gear 107 can obtain an angular speed and a linear speed much higher than those of the wheel 104, so that even if the wheel 104 rotates at a slow speed, the blower turbine 109 can generate wind at a faster rotation speed, thereby ensuring the blowing effect when the wheel 104 rotates at a slow speed.

[0043] The purpose of providing the gear box 201 is to protect the gears and prevent dust and impurities from entering between the gears and causing gear transmission obstruction.

[0044] Furthermore, a seed discharge pipe 301 is connected through the discharge port at the bottom of the seed slot 110, a flow regulating valve 302 is fixedly installed in the middle of the seed discharge pipe 301, and the flow regulating valve 302 is used to adjust the rate at which the seed slot 110 discharges seeds, and the seed discharge pipe 301 is arranged at the air outlet of the blower housing 106 at one end away from the seed slot 110; an air guide 401 is connected through the air outlet of the blower housing 106, and the air guide 401 is a soft pipe, and a seed spreading port 402 is connected through the end of the air guide 401 away from the blower housing 106, and the seed spreading port 402 is trumpet-shaped, and the seed discharge pipe 301 is connected through the air guide 401 above the end close to the blower housing 106, and the air guide 401 is used to guide the seeds discharged from the seed discharge pipe 301 to the seed spreading port 402 for sowing;

[0045] Among them, since the seed discharge pipe 301 at the bottom of the seed groove 110 is arranged perpendicular to the air duct 401, when fast-flowing air is introduced into the air duct 401, the seeds inside the seed discharge pipe 301 can be sucked downward according to the siphon principle, and the suction force can be used to prevent the seeds from gathering and clogging the seed discharge pipe 301, thereby ensuring the normal discharge of grass seeds.

[0046] Furthermore, a driving gear 501 is fixedly connected to the middle of the wheel axle 103, a transmission rod 502 is horizontally arranged below the mounting plate 102, the transmission rod 502 is fixedly connected to a first worm 503 at one end close to the driving gear 501, the first worm 503 is meshed with the driving gear 501, the transmission rod 502 is fixedly connected to a second worm 504 at one end away from the first worm 503, the mounting plate 102 is provided with an adjustment slot 509 below the air duct 401, a transmission shaft 506 is vertically rotatably installed inside the adjustment slot 509, the transmission shaft 506 is slidably arranged inside the adjustment slot 509, the transmission shaft 506 is fixedly connected to a driven gear 505 at one end located at the bottom of the mounting plate 102, the driven gear 505 is meshed with the second worm 504, the transmission shaft 506 is fixedly connected to an eccentric rotating disk 507 at one end located at the top of the mounting plate 102, The eccentric rotating disk 507 is arranged between the mounting plate 102 and the air duct 401, and a driving shaft 508 is vertically fixedly connected to the edge of the upper surface of the eccentric rotating disk 507, and a swing frame 510 is fixedly connected to the lower surface of the air duct 401, and a swing slide groove 511 is opened through the middle of the swing frame 510, and the driving shaft 508 is slidably arranged inside the swing slide groove 511, and the eccentric rotating disk 507 is used to drive the air duct 401 to swing through the driving shaft 508; the transmission rod 502 is rotatably mounted with a first mounting seat 601 at the end where the first worm gear 503 is located, and one end of the transmission rod 502 is rotatably mounted on the lower surface of the mounting plate 102 through the first mounting seat 601, and the transmission rod 502 is rotatably mounted on the end where the second worm gear 504 is located. The second mounting seat 602 is rotatably mounted, and the other end of the transmission rod 502 is rotatably mounted on the lower surface of the mounting plate 102 through the second mounting seat 602;

[0047] Among them, since the first worm 503 and the second worm 504 are respectively provided at both ends of the transmission rod 502, they can transmit the rotation of the driving gear 501 to the driven gear 505, and the driven gear 505 can drive the eccentric rotating disk 507 to rotate, and the driving shaft 508 on the upper surface of the eccentric rotating disk 507 will follow and make circular motion. Since the swinging groove 511 is in the shape of a long strip, the movement component of the driving shaft 508 along the swinging groove 511 will make it slide inside the swinging groove 511, and the movement component of the driving shaft 508 perpendicular to the swinging groove 511 will drive the movable end of the air guide 401 to swing through the swing frame 510, so as to achieve the swinging effect of the seed spreading port 402;

[0048] Among them, the adjustment slide groove 509 is long and strip-shaped, and the transmission shaft 506 is rotatably connected to the adjustment slide groove 509 through a bearing. At the same time, the transmission shaft 506 can also slide inside the adjustment slide groove 509 through the bearing, and its sliding does not affect the rotation of the transmission shaft 506; specifically, a freely slidable slider can be provided inside the adjustment slide groove 509, and then the transmission shaft 506 is vertically rotatably installed on the slider through the bearing, so that the sliding and rotation effects of the transmission shaft 506 can be guaranteed at the same time; the effect of rotating the transmission shaft 506 inside the adjustment slide groove 509 is to adjust the swing angle of the air duct 401. When the transmission shaft 506 moves to the side of the air duct 401 close to the blower housing 106, the swing angle of the air duct 401 increases, thereby increasing the area of ​​seed sowing. When the transmission shaft 506 moves to the side of the air duct 401 close to the seed spreading port 402, the swing angle of the air duct 401 decreases, thereby reducing the area of ​​seed sowing.

[0049] Furthermore, the two ends of one side of the mounting frame 101 are respectively fixedly connected with a connecting frame 701, and the end of the connecting frame 701 away from the mounting frame 101 is fixedly connected with a connecting seat 702, and the connecting seat 702 is used to connect to the driving vehicle. The mounting frame 101 is connected to the rear of the driving vehicle through the connecting frame 701 and the connecting seat 702.

[0053] S2, start the fan:

[0054] When the mounting frame 101 is pulled by the driving vehicle, the wheel 104 rotates due to friction with the ground, and the rotation of the wheel 104 drives the wheel axle 103 to rotate, and the wheel axle 103 drives the second speed gear 204 to rotate through the driving gear 105, and the second speed gear 204 drives the blower gear 107 to rotate through the first speed gear 203 coaxially arranged therewith, and the blower gear 107 drives the blower turbine 109 to rotate at high speed through the blower shaft 108, and the wind force generated when the blower turbine 109 rotates inside the blower housing 106 will spread the seeds dropped inside the seed slot 110 through the seed spreading port 402 through the air guide pipe 401;

[0055] S3, swing spreading:

[0056] When the wheel axle 103 rotates, it drives the transmission rod 502 to rotate through the driving gear 501 and the first worm 503. The transmission rod 502 drives the transmission shaft 506 to rotate through the second worm 504 and the driven gear 505. The rotation of the transmission shaft 506 drives the driving shaft 508 to perform eccentric movement inside the swinging slide 511 through the eccentric turntable 507, and then drives the soft air guide 401 to swing and sow through the swing frame 510, thereby expanding the sowing area of ​​the seed spreading port 402.

[0057] In summary, the present invention connects the mounting frame 101 to the rear of the driving vehicle through the connecting frame 701, and utilizes the wheel 104 to rotate and drive the blower turbine 109 to generate wind force inside the blower housing 106, so that the grass seeds dropped from the seed slot 110 can be sprayed out through the soft air guide 401 for long-distance sowing.
