Description

Technical Field

[0001] The invention relates to the field related to forestry cultivation and planting, and in particular to a forestry cultivation and planting ditching device and a working method thereof. Background Art

[0002] As global awareness of environmental protection increases and the concept of sustainable development becomes more popular, forestry cultivation, as an important means of ecological construction and environmental restoration, has received more and more attention from governments and people around the world. Forestry cultivation not only helps to improve air quality and maintain water and soil balance, but also provides abundant timber resources and diverse ecological services. In the process of forestry cultivation, trenching is a prerequisite for operations such as sowing, transplanting and irrigation. Traditional planting methods usually rely on manual use of tools such as drilling machines and shovels to dig tree pits. This method is not only labor-intensive and inefficient, but also difficult to unify the depth and width of trenching, resulting in limited space for the root development of planted trees, which is not conducive to the healthy growth of trees. In addition, due to the influence of factors such as soil hardness and complex terrain, traditional trenching methods often cannot ensure the linearity and depth consistency of the trench, thus affecting the planting quality. Therefore, mechanized trenching is becoming more and more widely used.

[0003] Mechanized ditching has the advantages of high efficiency, good operation quality and low labor intensity, and has become an important means in modern forestry production. For example, the Chinese authorized patent with the announcement number CN 215774209 U (a disc fertilizer ditching device) includes a fixed seat, a ditching device body, an adjustment spring, an upper pull rod, a lower pull rod, a ditching disc, a depth limiting component, a spring connecting rod and a depth limiting regulator. The fixed seat, the ditching device body, the upper pull rod and the lower pull rod form a parallel four-bar structure, which ensures that the meshing point is fixed during operation. The depth limiting component and the ditching disc change their relative positions through the depth limiting regulator, ensuring the stability of the fertilization depth.

[0004] In the above patent, the depth limiting component and the trenching disc can change their relative positions through a depth limiting adjuster, so as to facilitate the adjustment of the trenching depth; however, the soil will become hardened during long-term cultivation, and the roots and stems of plants will remain in the soil. It is more difficult for the trenching component to open trenches in the hardened soil, and the broken soil blocks are large in size and fall back into the trench after the trenching component passes. In addition, the root and stem parts of the plants will entangle the trenching component and move with it, and pull the soil as the roots and stems of the plants move, so that the trench is covered with soil again.

In the invention, the synchronous rotation of multiple planting trenching components is realized by driving the cutting drive motor and the central drive shaft, which greatly improves the efficiency and quality of trenching. The rotation of multiple planting trenching components drives the C-shaped connecting bracket to rotate. The soil cutting blade can efficiently cut the soil with the rotation of the C-shaped connecting bracket, so that the surface of the compacted soil is cut, so that the compacted soil will not be broken into large-sized soil blocks due to the movement of the trenching parts, so there will be no situation where large-sized soil is re-adjusted into the trench; and the soil cutting blade can cut the rhizomes of plants, thereby avoiding pulling the rhizomes of plants, facilitating subsequent soil trenching operations, solving the problem that the trenching of the trenching parts in the compacted soil is difficult, and the rhizomes of the plants will be entangled on the trenching parts and move with them, and pull the soil with the movement of the rhizomes of the plants, and the trench will be covered with soil again, which greatly improves the efficiency and quality of trenching.

In the invention, two inward-shaped inner vertical fixing plates are located on both sides of the rear end of the trenching member, and the minimum distance between the two inward-shaped inner vertical fixing plates is smaller than the maximum width of the trenching member. The inward-shaped inner vertical fixing plates will move along the opened trench and gather the soil in the trench with the movement of the driving device; at the same time, the inward-shaped outer vertical fixing plates and the straight outer vertical fixing plates work together with the inward-shaped horizontal fixing plates and the straight horizontal fixing plates to neatly arrange the soil gathered during the trenching process to avoid soil scattering and affecting the working effect, thereby greatly improving the trenching efficiency and reducing repeated trenching.

The lower end of the C-shaped limit bracket 29 is rotatably connected to a connecting turntable 30. The two ends of the connecting turntable 30 are fixed with a first fixed plate 31. The outer side of the first fixed plate 31 is fixedly connected to a second fixed plate 32 through a sleeve. The second fixed plate 32 is rotatably connected to the C-shaped limit bracket 29 through a bearing. The two first fixed plates 31 are arranged in an outer annular array with a C-shaped connecting bracket 33. The C-shaped connecting bracket 33 is fixed to the first fixed plate 31 by bolts. The internal array of the C-shaped connecting bracket 33 is fixed with a partition plate 34 to form a soil passing groove 35. The partition plate 34 is provided with a soil cutting blade 36 along the end of the rotation direction.

[0052] This design enables the soil cutting blade 36 to efficiently cut the soil as the C-shaped connecting bracket 33 rotates, so that the surface of the compacted soil is cut open, and the compacted soil does not form large-sized soil blocks; and the roots of plants can be cut, which is convenient for subsequent soil trenching operations, greatly improving the trenching efficiency and quality.

[0058] 4. External soil limiting and leveling components

[0059] The external soil limiting and leveling assembly 15 includes a straight inner vertical fixing plate 20, an inward-shaped inner vertical fixing plate 21, a straight outer vertical fixing plate 16, an inward-shaped outer vertical fixing plate 17, a straight horizontal fixing plate 18 and an inward-shaped horizontal fixing plate 19, etc. These components together form a soil leveling area to level and limit the soil after trenching.

[0060] The straight inner vertical fixing plate 20 is located at the rear end of the inward-retracted inner vertical fixing plate 21, and the arc surface between the straight inner vertical fixing plate 20 and the inward-retracted inner vertical fixing plate 21 is smoothly transitioned. The two inward-retracted inner vertical fixing plates 21 are located on both sides of the rear end of the groove opening member 24, and the minimum distance between the two inward-retracted inner vertical fixing plates 21 is less than the maximum width of the groove opening member 24;

[0061] The straight outer vertical fixing plate 16 and the inward-retracted outer vertical fixing plate 17 are welded and fixed to both sides of the lower end of the upper longitudinal fixing plate 14, and the straight outer vertical fixing plate 16 is located at the rear end of the inward-retracted outer vertical fixing plate 17, and the arc surface between the straight outer vertical fixing plate 16 and the inward-retracted outer vertical fixing plate 17 is smoothly transitioned;

[0062] The straight transverse fixing plate 18 is welded and fixed between the straight outer vertical fixing plate 16 and the straight inner vertical fixing plate 20. The straight transverse fixing plate 18 is arranged horizontally. The inward-retracted transverse fixing plate 19 is located at the front end of the straight transverse fixing plate 18.

[0063] The inward-retracted outer vertical fixing plate 17, the inward-retracted transverse fixing plate 19 and the inward-retracted inner vertical fixing plate 21 are all retracted toward the soil leveling area.

[0064] This design can ensure the flatness and uniformity of the soil after trenching, providing convenience for subsequent planting work, while improving land utilization and crop yields.

[0065] 5. The working method of the forestry cultivation and planting furrowing device of the present invention comprises the following steps:

[0066] 5.1 Initial movement and transmission start

[0067] The device is first moved by an external drive device (such as a tractor) to the designated working land. Then, the cutting drive motor 37 is started to drive the first bevel gear 39 to rotate. Through the meshing connection between the first bevel gear 39 and the second bevel gear 40, the second bevel gear 40 and the central drive shaft 38 rotate synchronously, thereby driving the connecting turntables 30 on the multiple planting and furrowing assemblies 28 to rotate synchronously, preparing for the subsequent soil cutting and furrowing operations.

[0068] 5.2 The device is pressed down and in contact with the soil

[0069] When the device reaches the predetermined position, the output rod ends of the first driving hydraulic cylinder 7 and the second driving hydraulic cylinder 10 extend simultaneously, pushing the rotating arm 5 to move vertically downward as a whole. At this time, the ditching member 24 and the planting ditching assembly 28 contact the soil and gradually embed into the soil, providing a basis for the subsequent ditching operation.

[0070] 5.3 Soil cutting and loosening

[0071] As the outer drive device continues to move, the cutting drive motor 37 remains in operation. The partition plate 34 inside the C-shaped connecting bracket 33 drives the soil cutting blade 36 to rotate, contact and cut the soil, so that the soil at the trenching position is loosened, which creates favorable conditions for the subsequent trenching operation.

[0072] 5.4 Trenching and soil preparation

[0073] The trenching member 24 is inserted into the loosened soil, and moves in the soil with the movement of the driving device to perform the actual trenching operation. The intermediate spring rod 26 provides the necessary buffering effect in this process to ensure the smooth progress of the trenching process. At the same time, the inward-retracted inner vertical fixing plate 21 is inserted into the trench, and gathers the soil in the trench with the movement of the driving device. Through the synergistic effect of the straight inner vertical fixing plate 20, the soil on the side of the trench opened is kept neat. In addition, the inward-retracted outer vertical fixing plate 17 and the straight outer vertical fixing plate 16 work together with the inward-retracted horizontal fixing plate 19 and the straight horizontal fixing plate 18 to neatly arrange the soil gathered in the trenching process to prevent the soil from scattering and affecting the operation effect.

[0074] 5.5 Grooving depth adjustment

[0075] According to the operation requirements, the up and down movement of the ditching member 24 and the planting ditching assembly 28 can be achieved by adjusting the extension or contraction of the output rod ends of the first driving hydraulic cylinder 7 and the second driving hydraulic cylinder 10. When the ditching depth needs to be increased, the output rod ends of the two hydraulic cylinders are extended at the same time; conversely, when the ditching depth needs to be reduced, the output rod ends of the two hydraulic cylinders are contracted at the same time. This flexible adjustment method enables the device to adapt to the ditching operation requirements of different depths.

[0076] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
