Description

Technical Field

[0001] This utility model belongs to the field of soil remediation technology, specifically relating to a grassland ecological restoration device. Background Technology

[0002] Alpine grassland restoration requires differentiated measures based on varying degrees of degradation, with the core focus on enhancing the grassland's self-recovery capacity supplemented by human intervention. In the restoration of severely degraded alpine grasslands, a restoration technology system of "tillage + fertilization + reseeding" is generally used. Currently, most alpine grassland restoration involves reseeding perennial forage grasses such as *Leymus chinensis*. However, the soil layer in alpine regions is thin and not easily disturbed, and the winds are strong, while degraded land has poor wind resistance. Grass seeds sown directly on the ground are easily blown away, hindering the restoration of degraded land. Utility Model Content

[0003] Based on the problems mentioned in the background technology above, this utility model provides a grassland ecological restoration device to solve the problem that the soil layer in high-altitude and cold regions should not be disturbed, and grass seeds directly sown on the ground are easily blown to other places by the wind, affecting the restoration of degraded land.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A grassland ecological restoration device includes a support rod and a base frame. The base frame has a handrail and a first mounting frame, on which are casters. A second mounting frame is also on the base frame, housing a soil-breaking roller and a rotating shaft. The soil-breaking roller is coaxially connected to a drive wheel, which is then connected to the rotating shaft. The soil-breaking roller has several conical nails, which loosen the soil by drilling holes in the ground as it rolls, minimizing disturbance to the soil layer. A camshaft is mounted on the rotating shaft. A seeding component is mounted on the base frame, comprising a first hopper and a discharge plate. The first hopper is mounted on the base frame and has several material distribution holes at its bottom. The discharge plate is slidably mounted on the bottom of the first hopper and has discharge holes that match the material distribution holes. A tension spring connects the discharge plate and the first hopper; when the spring is in its natural state, the discharge holes are misaligned with the material distribution holes. An arc-shaped top plate corresponding to the camshaft is mounted on the discharge plate.

[0006] Based on the above technical solution, the present invention has made the following improvements:

[0007] Furthermore, a carbon application assembly is installed on the base frame. The carbon application assembly includes a second hopper, with a closed-end tube connected to the bottom of the second hopper. The top of the tube communicates with the second hopper, and a discharge chute is provided at the bottom of the tube. A carbon application roller is rotatably mounted inside the tube, and multiple material-collecting slots are provided on the circumference of the carbon application roller. The carbon application roller is connected to a drive wheel. The second hopper can be used to hold additives that increase soil fertility, such as biochar and organic fertilizer. When the soil-breaking roller rolls on the ground, it drives the carbon application roller to rotate, spreading the biochar or organic fertilizer from the second hopper onto the ground through the material-collecting slots.

[0008] Furthermore, the first hopper is located behind the soil-breaking roller, and the second hopper is located in front of the soil-breaking roller. After the biochar in the second hopper is sprinkled on the ground, it can be pressed into the soil layer by the conical nails on the soil-breaking roller, while the seeds are scattered behind the soil-breaking roller, which can prevent the seeds from being damaged by rolling.

[0009] Furthermore, the front end of the base frame has a slot, within which an auxiliary wheel assembly is installed. The auxiliary wheel assembly includes a base shaft, a wheel frame on the base shaft, and rollers mounted on the wheel frame. Both ends of the base shaft have square shafts that match the slot, and each square shaft has a limiting plate that contacts the inner side of the base frame. A pin passes through the base frame to prevent the square shafts from sliding out of the slot. When sowing is not required, the auxiliary wheel assembly can be rotated to bring the rollers to the ground. The support from the rollers and two omnidirectional wheels prevents the soil-breaking roller from suspending in the air and avoids contact between the cone nail and the ground, thus preventing the cone nail from damaging the ground during transport.

[0010] Furthermore, both the rollers and casters are equipped with anti-slip teeth on their circumference. This increases the grip of the rollers and casters, allowing the device to move more effectively on the ground.

[0011] Furthermore, a baffle plate is installed on the first hopper, and the baffle plate contacts the inner bottom of the first hopper. When sowing is not required, the baffle plate can be inserted into the first hopper to block the material distribution hole, preventing the discharge hole from aligning with the material distribution hole when the device stops moving, thus avoiding continuous falling of grass seeds from the first hopper.

[0012] The beneficial effects of this utility model are:

[0013] When pushing the base frame, the soil-breaking roller can be pushed to roll on the ground and make holes in the ground under the action of the cone nail to accommodate grass seeds. The disturbance to the soil layer is small. After the grass seeds are dispersed through the distribution hole, they are scattered on the ground through the discharge hole. Some grass seeds fall into the holes in the ground to facilitate grass seed growth. At the same time, it can prevent grass seeds from being blown away by the wind. It is suitable for grassland restoration in high-altitude and cold regions. Attached Figure Description

Detailed Implementation

[0025] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this utility model. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] like Figures 1-7 As shown, a grassland ecological restoration device includes a support rod and a base frame 1. The base frame 1 has a handrail 13 and a first mounting frame 11, on which casters 12 are mounted. The base frame 1 also has a second mounting frame 10, on which a soil-breaking roller 3 and a rotating shaft 33 are mounted. The soil-breaking roller 3 is coaxially connected to a drive wheel 32, which is connected to the rotating shaft 33 via a transmission belt. When the soil-breaking roller 3 rotates, it drives the rotating shaft 33 to rotate synchronously. The soil-breaking roller 3 has several conical nails 31. When the soil-breaking roller 3 rolls on the ground, it can loosen the soil by drilling holes in the ground with the conical nails 31, minimizing disturbance to the soil layer. A camshaft 34 is mounted on the rotating shaft 33, and a seeding component 2 is mounted on the base frame 1. The seeding component 2 includes a first hopper 21 and a discharge plate 23. The first hopper 21 is mounted on the base frame 1 and has several feeding holes 211 at its bottom. The discharge plate 23 is slidably mounted on the bottom of the first hopper 21. The discharge plate 23 has ear plates 232 with grooves at both ends. The first hopper 21 has protrusions 22 located in the grooves on the ear plates 232. The discharge plate 23 has discharge holes 231 that match the feeding holes 211. A tension spring 24 connects the discharge plate 23 and the first hopper 21. One end of the tension spring 24 is connected to the ear plate 232, and the other end is connected to the first hopper 21. When the tension spring 24 is in its natural state, the discharge holes 231 and the feeding holes 211 are misaligned. An arc-shaped top plate 233 corresponding to the camshaft 34 is mounted on the discharge plate 23.

[0027] like Figure 2 , Figure 3 As shown, a carbon application assembly 5 is installed on the base frame 1. The carbon application assembly 5 includes a second hopper 51, with a pipe 52 closed at both ends connected to the bottom of the second hopper 51. The top of the pipe 52 communicates with the second hopper 51, and a discharge trough 521 is opened at the bottom of the pipe 52. A carbon application roller 53 is rotatably installed inside the pipe 52. Multiple material collection grooves 54 are opened on the circumference of the carbon application roller 53. The carbon application roller 53 is connected to the drive wheel 32 for transmission. The second hopper 51 can be used to hold additives such as biochar and organic fertilizer to increase soil fertility. When the soil breaking roller 3 is pushed to roll on the ground, it can drive the carbon application roller 53 to rotate, and the biochar or organic fertilizer in the second hopper 51 is spread on the ground through the material collection grooves 54.

[0028] like Figure 1 , Figure 3 As shown, the first hopper 21 is located behind the soil-breaking roller 3, and the second hopper 51 is located in front of the soil-breaking roller 3. After the biochar in the second hopper 51 is sprinkled on the ground, it can be pressed into the soil layer by the conical nails 31 on the soil-breaking roller 3. The seeds are scattered behind the soil-breaking roller 3, which can avoid the seeds being damaged by rolling.

[0029] like Figure 1 , Figure 2 and Figure 8 As shown, a slot 14 is provided at the front end of the base frame 1. An auxiliary wheel set 4 is installed in the slot 14. The auxiliary wheel set 4 includes a base shaft 41, a wheel frame 42 on the base shaft 41, and rollers 43 mounted on the wheel frame 42. Square shafts 44 matching the slot 14 are provided at both ends of the base shaft 41. Each square shaft 44 is provided with a limiting piece 45, which contacts the inner side of the base frame 1. A pin 15 passes through the base frame 1 to prevent the square shafts 44 from sliding out of the slot 14. When sowing is not required, the auxiliary wheel set 4 can be rotated to bring the rollers 43 to the ground. The support of the rollers 43 and the two casters 12 prevents the soil-breaking roller 3 from being suspended in the air and avoids the cone nail 31 from contacting the ground, thus preventing the cone nail 31 from damaging the ground during transport. Anti-slip teeth are provided on the circumference of both the rollers 43 and the casters 12, increasing the grip of the rollers 43 and the casters 12, allowing the device to be pushed more effectively on the ground.

[0030] like Figures 4-7 As shown, a baffle plate 25 is provided on the first hopper 21. The baffle plate 25 contacts the inner bottom of the first hopper 21. When there is no need to sow seeds, the baffle plate 25 can be inserted into the first hopper 21 to block the material distribution hole 211, so as to prevent the discharge hole 231 from being exactly aligned with the material distribution hole 211 when the device stops moving, which would cause the grass seeds in the first hopper 21 to continue to fall.

[0031] In use, first hopper 21 is filled with grass seeds to be sown, and second hopper 51 is filled with biochar or other nutrients. After moving the device to the area needing restoration, the auxiliary wheel assembly 4 is removed, rotated, and then reinstalled into the slot 14, avoiding contact between the roller 43 and the ground (e.g., ...). Figure 9 (As shown), the device is then moved. When the soil-breaking roller 3 rotates, it drills holes in the ground through the cone nail 31. When the soil-breaking roller 3 rotates, it synchronously drives the carbon-applying roller 53 and the camshaft 34 to rotate. When the carbon-applying roller 53 rotates, it can spread the nutrients in the second hopper 51 onto the ground. When the camshaft 34 rotates, it can intermittently push the discharge plate 23 to move repeatedly. When the discharge plate 23 moves, the discharge hole 231 and the distribution hole 211 correspond to each other, so that the grass seeds are scattered on the ground. Some grass seeds fall into the holes drilled by the cone nail 31, which can prevent the grass seeds from being blown away by the wind. At the same time, the temperature inside the soil hole is slightly higher than that on the ground surface, which is conducive to the germination and growth of grass seeds, and the repair effect is better.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
