[0015] Preferably, a movable base is installed on each of the two fixed frames on the side away from each other, and the movable base is used for moving the equipment.

[0016] A preferred method for planting a planting device for grassland ecological restoration is as follows:

[0017] S1. Equipment Placement: Move the equipment to the land where grass seeds need to be sown, and at the same time turn on the drive module to drive the active belt roller to rotate, thereby driving the conveyor belt to move.

[0018] S2, Soil preparation: As the equipment moves, the shovel plate shovels up the soil from the top layer of the land, and the soil falls onto the conveyor belt. As the conveyor belt moves to the other end, the heating plate heats and dries the soil when it is in the horizontal section of the conveyor belt.

[0019] S3. Fine soil preparation: When the active belt roller rotates, the two rotating drums rotate relative to each other through the first gear and the end gear ring. When the dried soil falls between the two rotating drums, the crushing blocks on the rotating drums crush the soil.

[0020] S4. Fine soil transfer: The fine soil falls into the collection box. The rotating drum rotates, which drives the connecting cylinder to rotate, bringing the fine soil in the collection box into the fine soil storage cylinder.

[0021] S5, Grass Seed Feeding: After some fine soil enters the fine soil storage cylinder, a certain amount of grass seeds are fed from the material box into the grass seed storage cylinder.

[0022] S. Grass Seed Spreading: As the equipment moves, when the square groove on the rotating drum aligns with the discharge hole, grass seeds are discharged for spreading. When the square groove on the other rotating drum aligns with the discharge chute, fine soil is discharged, thus covering the grass seeds with a layer of fine soil to protect them.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1) During operation, a heating plate is installed on the inner side of the conveyor belt to dry the shoveled soil, which is convenient for the subsequent formation of fine soil. As the two rotating drums rotate, while grass seeds and fine soil are being discharged, the dried soil falls between the two rotating drums and is crushed by the crushing blocks on the rotating drums, breaking the large pieces of dried soil into fine soil, which is convenient for covering and protecting the grass seeds after sowing.

[0025] 2) During operation, grass seeds are stored inside the grass seed storage cylinder, while fine soil is stored inside the fine soil storage cylinder. The grass seed storage cylinder is located on the side of the fine soil storage cylinder closer to the direction of equipment movement. After the grass seeds are sown, a layer of fine soil is laid at the sowing location to protect the grass seeds, prevent them from being blown away by the wind, and prevent the covering material from hindering the growth of the grass seeds.

[0026] 3) During operation, the first gear on the active belt roller meshes with the end gear ring of the rotating drum outside the grass seed storage cylinder, so that while driving the active belt roller to rotate and moving the conveyor belt to complete the soil transfer, it can also drive the two rotating drums to rotate relative to each other, which facilitates subsequent soil crushing, reduces the number of drive components, simplifies the structure, and makes maintenance easier.

[0027] 4) During operation, the rotating cylinder is driven to rotate rapidly by the internal tooth ring, the second gear and the external tooth ring. Then, the fan blades on its inner wall drive the air circulation, which in turn drives the fine soil falling into the collection box into the fine soil storage cylinder, making it convenient for subsequent fine soil covering.

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] Depend on Figures 1-8 The present invention relates to a planting device for grassland ecological restoration, comprising two fixed frames 1, a fine soil preparation component 4 disposed between the two fixed frames 1, a soil transfer component 3 disposed on the top of the fixed frames 1, a movable base 2 installed on the side of the two fixed frames 1 that is far apart from each other, the movable base 2 being used for moving the device, and a grass seed storage cylinder 4011 installed between the two fixed frames 1.

[0041] The fine soil preparation component 4 includes a material storage unit 401 disposed between two fixed frames 1. The material storage unit 401 includes a fine soil storage cylinder 4012 installed between the two fixed frames 1. The fine soil storage cylinder 4012 is arranged parallel to the grass seed storage cylinder 4011. The grass seed storage cylinder 4011 is used for sowing grass seeds, and the fine soil storage cylinder 4012 is used to cover the grass seeds with a layer of fine soil after sowing. The grass seed storage cylinder 4011 stores grass seeds, while the fine soil storage cylinder 4012 stores fine soil. The grass seed storage cylinder 4011 is located on the side of the fine soil storage cylinder 4012 closest to the direction of equipment movement. After sowing grass seeds, a layer of fine soil is laid at the sowing location to protect the grass seeds, preventing them from being blown away by the wind and also preventing the covering material from being blown away. To hinder the growth of grass seeds, a soil crushing component 402 is provided on the outside of the grass seed storage cylinder 4011 and the fine soil storage cylinder 4012. A fixed shaft is coaxially installed at one end of the grass seed storage cylinder 4011 and the fine soil storage cylinder 4012. The fixed shaft is fixedly installed to one of the fixed frames 1. A feed pipe 4013 is coaxially installed at the other end of the grass seed storage cylinder 4011 and the other end of the fine soil storage cylinder 4012. The feed pipe 4013 is connected to another fixed frame 1. A material box 4014 is fixedly installed on one side of the fixed frame 1. The discharge pipe of the material box 4014 is connected to the feed pipe 4013 on the grass seed storage cylinder 4011. A fine soil transfer component 403 is provided on the feed pipe 4013 on the fine soil storage cylinder 4012.

[0042] A collection box 4015 is provided below the grass seed storage cylinder 4011 and the fine soil storage cylinder 4012. A connecting main pipe 4016 is provided below the collection box 4015. A longitudinal connecting pipe is installed at equal intervals between the connecting main pipe 4016 and the bottom of the collection box 4015. One end of the connecting main pipe 4016 is connected to the end of the feed pipe 4013 on the fine soil storage cylinder 4012 away from the fine soil storage cylinder 4012. The collection box 4015 is fixedly connected to the fixing frame 1. The bottom end of the grass seed storage cylinder 4011 is provided with discharge holes 4017 at equal intervals. The bottom end of the fine soil storage cylinder 4012 is provided with a discharge trough 4018.

[0043] The soil crushing component 402 includes two rotating cylinders 4021 respectively fitted around the outer sides of the grass seed storage cylinder 4011 and the fine soil storage cylinder 4012. Square grooves 4022 are formed at equal angles on the rotating cylinders 4021. Crushing blocks 4023 are evenly installed on the outer walls of the rotating cylinders 4021. End toothed rings 4024 are installed at the same end of both rotating cylinders 4021, and the two end toothed rings 4024 mesh with each other. The square grooves 4022 on the two rotating cylinders 4021 are in the same position. When the square grooves 4022 are aligned with the discharge hole 401... When position 7 corresponds, grass seeds fall. When the square groove 4022 corresponds to the discharge groove 4018, fine soil is discharged. The first gear 308 on the active belt roller 302 meshes with the end gear ring 4024 of the rotating cylinder 4021 outside the grass seed storage cylinder 4011. This allows the active belt roller 302 to rotate and the conveyor belt 304 to move to complete the soil transfer. At the same time, it can drive the two rotating cylinders 4021 to rotate relative to each other, which facilitates subsequent soil crushing, reduces the number of drive components, simplifies the structure, and makes maintenance easier.

[0044] The fine soil transfer component 403 includes a central groove 4031 formed in the middle of a feed pipe 4013 connected to a fine soil storage cylinder 4012. Limiting heads 4032 are installed at both ends of the feed pipe 4013 within the central groove 4031. A connecting cylinder 4033 is provided on the central groove 4031, with both ends of the connecting cylinder 4033 rotatably connected to the two limiting heads 4032. Fan blades 4034 are installed at equal angles on the inner wall of the connecting cylinder 4033. An external gear ring 4035 is fixedly installed on the outer side of the connecting cylinder 4033, and a second gear 4036 is meshed with the outer side of the external gear ring 4035. The second gear 4036 is rotatably connected to the fixed frame 1. Next, an internal toothed ring 4037 is fixedly installed at one end of a rotating cylinder 4021 located outside the fine soil storage cylinder 4012. The internal toothed ring 4037 is coaxially arranged with the connecting cylinder 4033. The inner side of the internal toothed ring 4037 meshes with the second gear 4036. During the rotation of the rotating cylinder 4021, the internal toothed ring 4037, the second gear 4036 and the external toothed ring 4035 drive the connecting cylinder 4033 to rotate rapidly. Then, the fan blades 4034 on its inner wall drive the air circulation, which carries the fine soil that falls into the collection box 4015 into the fine soil storage cylinder 4012, which is convenient for subsequent fine soil covering.

[0045] The soil transfer assembly 3 includes a conveyor belt 304 positioned above the grass seed storage cylinder 4011. One end of the conveyor belt 304 is located above the middle of the two rotating cylinders 4021. A heating plate 309 is installed on the inner side of the conveyor belt 304 to dry the soil with high moisture content, facilitating the subsequent formation of fine soil. As the two rotating cylinders 4021 rotate, grass seeds and fine soil are discharged simultaneously. The dried soil falls between the two rotating cylinders 4021 and is crushed by the crushing blocks 4023 on the rotating cylinders 4021, breaking the large pieces of dried soil into fine soil. This facilitates the subsequent covering and preservation of grass seeds after sowing. The conveyor belt 304 includes a horizontal section above the grass seed storage cylinder 4011 and an inclined section on the side of the grass seed storage cylinder 4011 away from the fine soil storage cylinder 4012. A heating plate 309 is located inside the horizontal section of the conveyor belt 304. Side frames 301 are symmetrically arranged on both sides of the conveyor belt 304, with the shape of the side frames 301 corresponding to the side shape of the conveyor belt 304. The two side frames 301 are respectively fixed to the tops of two fixed frames 1. The heating plate 309 is fixedly installed to the fixed frames 1. A limiting roller 305 is installed between the two side frames 301. The limiting roller 305 is used to limit and support the conveyor belt 304. An active roller 302 is provided on the inner side of one end of the conveyor belt 304, and a driven roller 303 is provided on the inner side of the other end of the conveyor belt 304. Both the active roller 302 and the driven roller 303 are rotatably connected to the side frame 301. One end of the active roller 302 located above the grass seed storage cylinder 4011 is connected to a drive module 307. A first gear 308 is coaxially mounted on the active roller 302 located above the grass seed storage cylinder 4011. The first gear 308 meshes with the end gear ring 4024 at the end of the rotating cylinder 4021 located outside the grass seed storage cylinder 4011. A soil scraper 306 is fixedly installed at the bottom between the two side frames 301. The soil-shoveling plate 306 is located above the bottom of the inclined section of the conveyor belt 304. The grass seed storage cylinder 4011 is located directly below the horizontal section of the conveyor belt 304. Two rotating cylinders 4021 are respectively rotatably installed on the outside of the grass seed storage cylinder 4011 and the fine soil storage cylinder 4012, and a soil breaking gap is formed between the two rotating cylinders 4021. The end of the horizontal section of the conveyor belt 304 away from its inclined section is the soil output end. The soil output end of the conveyor belt 304 is located directly above the soil breaking gap. The heating plate 309 is composed of a heat-conducting support plate and a heating coil. After the heating coil is energized, it heats up and dries the soil on the upper conveyor belt 304.

[0046] Working principle: During operation, the equipment is first moved to the land where grassland ecological restoration is needed. Then, the equipment is turned on and moved towards the side of the shovel plate 306. At the same time, the drive module 307 is turned on to drive the active belt roller 302 to rotate, which in turn drives the conveyor belt 304 to move. This causes the upper surface of the conveyor belt 304 to move away from the shovel plate 306. During the movement, the shovel plate 306 inserts into the soil and shovels out the upper layer of soil, causing the upper layer of soil to fall onto the upper surface of the conveyor belt 304. As the conveyor belt 304 moves towards its horizontal section, the heating plate 309 installed inside the conveyor belt 304 heats and dries the shoveled soil. Then, the soil falls from the end of the conveyor belt 304 into the gap between the two rotating drums 4021.

[0047] When the drive roller 302 rotates, the first gear 308 on the drive roller 302 meshes with the end toothed ring 4024 at the end of the outer rotating cylinder 4021 of the grass seed storage cylinder 4011. At the same time, the end toothed rings 4024 at the ends of the two rotating cylinders 4021 mesh, so that the two rotating cylinders 4021 rotate in opposite directions while the conveyor belt 304 moves. During the process of soil falling between the two rotating cylinders 4021, the dried soil is crushed by the breaking blocks 4023 on the outer wall of the rotating cylinder 4021, turning it into fine soil. Then the fine soil falls into the collection box 4015 and is collected.

[0048] Simultaneously, during the synchronous rotation of the rotating cylinder 4021, the internal toothed ring 4037 is driven to rotate. A second gear 4036 meshes between the internal toothed ring 4037 and the external toothed ring 4035 on the outer side of the connecting cylinder 4033. This causes the rotating cylinder 4021 to rotate, driving the connecting cylinder 4033 to rotate. Furthermore, the diameter of the internal toothed ring 4037 is much larger than the diameter of the external toothed ring 4035 and the diameter of the second gear 4036, allowing the rotating cylinder 4021 to rotate slowly while simultaneously driving the connecting cylinder 4033 to rotate. 033 rotates rapidly. During the rotation of the connecting cylinder 4033, the fan blades 4034 on its inner wall drive air circulation, thereby carrying the fine soil that has fallen into the collection box 4015 through the connecting main pipe 4016 and the feed pipe 4013 into the fine soil storage cylinder 4012. The fan blades 4034 are installed inside the connecting cylinder 4033. When the connecting cylinder 4033 rotates, it forms a "fan" that drives air circulation. The air circulation direction is from the collection box 4015 to the fine soil storage cylinder 4012. At the same time, the attached... Figure 4 and attached Figure 6The diameter of the inner tooth ring 4037 is much larger than that of the outer tooth ring 4035, which allows the connecting cylinder 4033 to rotate rapidly while the rotating cylinder 4021 rotates normally. This, in turn, enables the fan blade 4034 to exert a strong force on the air. The collection box 4015 contains dry fine soil, which is mainly composed of soil particles with small particle size and fine texture, usually in the form of silt (particle size 0.002 to 0.05 mm). Although the fine soil has weight, it is relatively light. During the air circulation, the light fine soil is carried into the fine soil storage cylinder 4012. When covering the seeds with soil, only a thin layer of fine soil needs to be covered, so the demand for fine soil is not large and it is easier to be carried into the fine soil storage cylinder 4012.

[0049] After some fine soil enters the fine soil storage cylinder 4012, grass seeds are put in from the material box 4014, and the grass seeds enter the grass seed storage cylinder 4011 for storage along the feed pipe 4013.

[0050] Then, as the rotating drum 4021 continues to rotate, when the rotating drum 4021 rotates to the position corresponding to the square groove 4022 and the discharge hole 4017, the grass seeds in the grass seed storage drum 4011 fall from the discharge hole 4017 onto the ground. At the same time, another rotating drum 4021 rotates to the position corresponding to the square groove 4022 and the discharge trough 4018, and the fine soil in the fine soil storage drum 4012 falls from the discharge trough 4018. This allows a thin layer of fine soil to be spread on the grass seeds after they fall, preventing the grass seeds from being blown away by the wind and avoiding hindering their growth. As the equipment continues to move, grass seeds are continuously sown.
