Description

Technical Field

[0001] This invention relates to the field of soil remediation technology, and in particular to a forest soil ecological restoration device based on carbon sequestration accounting. Background Technology

[0002] Carbon sequestration uses a series of scientific methods to quantitatively assess the changes in carbon storage or carbon absorption rate in a specific area, such as a forest, over a specific period. The results establish ecological value and form the basis for carbon trading and the formulation of management strategies. Among these, enhancing and stabilizing the soil carbon pool is one of the core objectives of forest carbon sequestration. Through ecological restoration of the soil, organic matter return and accumulation can be promoted, soil carbon stability can be enhanced, and carbon emissions caused by soil degradation can be reduced. Soil ecological restoration requires land preparation equipment to turn, break up, and mix the soil, providing a good foundation for subsequent replanting.

[0003] Existing land preparation equipment has fixed width dimensions, making it difficult to adapt to different width requirements and unable to create drainage ditches on both sides while tilling the land to meet specific needs. For example, Chinese patent CN212069923U discloses a mobile contaminated soil remediation device, in which the connecting frame used to fix the plow blade has a fixed size, making it impossible to adjust the tilling size per operation. Summary of the Invention

[0004] The purpose of this invention is to address the problem in the prior art that land preparation equipment has a fixed width and cannot simultaneously create drainage ditches on both sides, and to propose a forest soil ecological restoration device based on carbon sequestration accounting.

[0009] Preferably, it also includes a limiting bolt; multiple through holes are equidistantly arranged on the support rod, the plow blade holder is sleeved on the support rod, and there is a through hole at both ends of the plow blade holder, the limiting bolt passes through the through hole and is locked by a nut.

[0010] Preferably, two trenching plates are slidably installed at the bottom of the soil turning frame along the length of the support rod. The front end of the trenching plate is pointed, and the size increases towards the back. The trenching plate is provided with a middle avoidance hole and a tail avoidance hole to avoid the two support rods.

[0014] Example 1; as Figure 1 and Figure 5 As shown, the present invention proposes a forest soil ecological restoration device based on carbon sink accounting, including a soil turning frame 1. A hanging ring 2 is set on the front side of the soil turning frame 1, which is connected to a power-driven forward propulsion device such as a tractor, agricultural vehicle, or other traction machine to achieve forward movement. Two support rods 3 are rotatably set at the bottom of the soil turning frame 1. The length direction of the support rods 3 is perpendicular to the forward direction. The two support rods 3 are arranged side by side. A plow frame 4 is slidably set on the support rods 3 along their length direction. Multiple plow blades 5 are set on the outer wall of the plow frame 4. The length of the plow frame 4 is less than half the length of the support rods 3. The soil turning frame 1 is equipped with a power mechanism that drives the two support rods 3 to rotate. By horizontally moving the position of the two plow frames 4, the width of soil turning can be adjusted, which can be easily adjusted as needed.

[0015] Furthermore, the support rod 3 is a square rod, and the plow frame 4 is provided with a square hole for the support rod 3 to pass through. Both ends of the support rod 3 are provided with a rotating shaft, which is rotatably connected to the soil turning frame 1. Specifically, the soil turning frame 1 is provided with a through hole for the rotating shaft to pass through, and a bearing is provided between the rotating shaft and the through hole.

[0016] Furthermore, multiple through holes 6 are equidistantly arranged on the support rod 3. The plow blade holder 4 is fitted onto the support rod 3. There is a through hole 6 at both ends of the plow blade holder 4. The limiting bolt 8 passes through the through hole and is locked with a nut. In an optional embodiment, two clearance grooves 7 are provided at both ends of the plow blade holder 4. The head of the limiting bolt 8 and the nut are engaged in the clearance groove 7. When it is necessary to adjust the position of the plow blade holder 4, the limiting bolt 8 can be removed. After the position of the plow blade holder 4 is adjusted, the limiting bolt 8 is passed through the through holes 6 at both ends of the plow blade holder 4 and locked with a nut. By adjusting the position of the two plow blade holders 4, the width of soil turning can be changed, and it can be flexibly adjusted according to needs.

[0017] Example 2; as Figures 1-3As shown, this invention proposes a forest soil ecological restoration device based on carbon sink accounting. Compared to Embodiment 1, this embodiment details the structure of the power mechanism. Specifically, the power mechanism includes a motor 12 and a reducer 13 mounted on the top of the soil turning frame 1, transmission wheels 9 mounted on the reducer 13 and two rotating shafts, a transmission component a10 connecting the two transmission wheels 9 on the two rotating shafts, and a transmission component b11 connecting the transmission wheels 9 on the rotating shafts and the transmission wheels 9 on the reducer 13. Specifically, the output end of the motor 12 is connected to the input end of the reducer 13, and a transmission wheel 9 is mounted on the output shaft of the reducer 13. There are two ways in which the components a10, b11, and 9 are coupled: one is that the 9 is a pulley and both a10 and b11 are belts; the other is that the 9 is a sprocket and both a10 and b11 are chains. In addition, to protect the power mechanism, the soil turning frame 1 is equipped with protective covers b15 and a14. The 9, a10, and b11 are located inside the protective cover b15, and the motor 12 and the reducer 13 are located inside the protective cover a14. The top of the protective cover a14 is also equipped with a maintenance plate. By opening the maintenance plate, the motor 12 and the reducer 13 can be inspected or replaced.

[0018] Furthermore, a counterweight 16 is installed on the top of the soil turning frame 1. The motor 12 and the reducer 13 are located on one side of the top of the soil turning frame 1, and the counterweight 16 is located on the other side of the top of the soil turning frame 1. The counterweight is used to balance the weight of the motor 12 and the reducer 13, adjust the center of gravity of the entire equipment, and make the center of gravity located in the middle position of the soil turning frame 1, thereby improving stability.

[0019] Example 3; as Figure 2 and Figure 4 As shown, the present invention proposes a forest soil ecological restoration device based on carbon sink accounting. Compared with Embodiment 1 or Embodiment 2, this embodiment details the relevant structure of trenching on both sides of the soil turning. Specifically, two trenching plates 23 are slidably arranged at the bottom of the soil turning frame 1 along the length of the support rod 3. The front end of the trenching plate 23 is pointed, and the size increases towards the back. The two trenching plates 23 are located on both sides of the tilling range of the two plow groups. Drainage ditches are made by the trenching plates. The trenching plates 23 are provided with a middle avoidance hole 17 and a tail avoidance hole 18 to avoid the two support rods 3.

[0020] Furthermore, a sliding frame 19 is provided on the top of the trenching plate 23, and two limiting plates 20 are provided at the bottom of the sliding frame 19. The two limiting plates 20 clamp the front crossbar of the soil turning frame 1 to realize the lateral sliding of the trenching plate 23. Multiple threaded holes 21 are provided at equal intervals on the front crossbar of the soil turning frame 1. An adjusting bolt 22 is provided on the sliding frame 19. The bottom of the adjusting bolt 22 is rotated and screwed into the threaded hole 21. The height of the trenching plate 23 can be changed by rotating the adjusting bolt 22, so as to open drainage ditches of different depths as needed. Alternatively, the trenching plate 23 can be raised completely without opening a ditch.

[0021] In summary, when using this invention, the width of the soil turning in one pass can be adjusted by adjusting the lateral position of the two plow blades 4, making it convenient to turn the soil according to actual needs. In addition, the ditching plates 23, which are slidably set on both sides, can open ditches on both sides of the width of the soil turning by the plow blades 5, so as to quickly form drainage ditches and facilitate the movement of management personnel. The ditching plates 23 can adapt to different soil turning widths and can also be raised and lowered, so they can be used to open ditches or not, making them quite flexible in use.

[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
