Description

TECHNICAL FIELD

[0001] The present application relates to the field of forestry cultivation and planting, in particular to a forestry cultivation and planting ditching device and a working method thereof. BACKGROUND

[0002] With the improvement of global environmental protection awareness and the deepening of the concept of sustainable development, forestry cultivation and planting, as an important means of ecological construction and environmental restoration, is increasingly valued by governments and the public around the world. Forestry cultivation not only helps to improve air quality, maintain soil balance, but also provides abundant timber resources and diversified ecological services. In the process of forestry cultivation and planting, ditching is a prerequisite for seeding, transplanting and irrigation. Traditional planting methods usually rely on manual use of drilling machines, shovels and other tools to dig tree holes. This method not only has high labor intensity and low efficiency, but also has difficulty in unifying the depth and width of the ditch, which limits the development space of the roots of the planted trees and is not conducive to the healthy growth of the trees. In addition, due to factors such as soil hardness and complex terrain, the traditional ditching method often cannot guarantee the linearity and depth consistency of the trench, thereby affecting the planting quality, so the application of mechanized ditching is becoming more and more widespread.

[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 publication number CN 215774209 U (a disc fertilizer ditching device) includes a fixed seat, a ditching body, an adjusting spring, an upper pull rod, a lower pull rod, a ditching disc, a depth limiting component, a spring connecting rod and a depth limiting adjuster. The fixed seat, the ditching body, the upper pull rod and the lower pull rod form a parallelogram structure to ensure that the engagement point position is fixed during work. The depth limiting component and the ditching disc change the relative position through the depth limiting adjuster to ensure the stability of the fertilization depth.

[0004] In the above-mentioned patent, the depth limiting component and the ditching disc can change the relative position through the depth limiting adjuster, which is convenient for adjusting the ditching depth; however, the soil will be hardened after a long period of cultivation, and the roots of plants will remain in the soil. It is difficult for the ditching element to dig in the hardened soil, and the size of the broken soil blocks is large. After the ditching element passes through, the broken soil blocks fall back into the ditch, and the roots of the plants will wrap around the ditching element and move with it, pulling the soil along with the movement of the plant roots, so that the ditch is covered with soil again.

The rotation of the multiple planting and ditching assemblies drives the rotation of the C-shaped connecting bracket, and the soil cutting blade can efficiently cut the soil along with the rotation of the C-shaped connecting bracket, so that the hardened soil surface is cut open, and the hardened soil will not be broken into large-sized soil blocks due to the movement of the ditching element, thus avoiding the situation that large-sized soil is re-adjusted into the ditch.

The inwardly-concave inner vertical fixed plates will move along the opened ditch and gather the soil in the ditch along with the movement of the driving device; at the same time, the inwardly-concave outer vertical fixed plate and the straight outer vertical fixed plate cooperate with the inwardly-concave horizontal fixed plate and the straight horizontal fixed plate to arrange the soil gathered in the ditching process in an orderly manner, avoiding the scattering of soil affecting the operation effect, greatly improving the ditching efficiency, and reducing the repeated ditching situation.

[0064] The design can ensure the flatness and neatness of the soil after ditching, provide convenience for subsequent planting work, and improve the utilization rate of land and the yield of crops.

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

[0066] 5.1 Initial movement and transmission start

[0067] The device is first moved by an external driving device (such as a tractor) to above the designated work land. Then, the cutting driving motor 37 is started to drive the first bevel gear 39 to rotate. Through the meshing connection relationship between the first bevel gear 39 and the second bevel gear 40, the second bevel gear 40 and the central driving shaft 38 rotate synchronously, thereby driving the connection rotating disc 30 on the plurality of planting and ditching assemblies 28 to rotate synchronously, so as to prepare for the subsequent soil cutting and ditching operation.

[0068] 5.2 Device pressing and soil contact

[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 are simultaneously elongated to push the rotating arm 5 to move vertically downward. At this time, the ditching piece 24 and the planting and ditching assembly 28 contact and gradually embed into the land, thereby providing a basis for the subsequent ditching operation.

[0070] 5.3 Soil cutting and loosening

[0071] As the external driving device continues to move, the cutting driving motor 37 remains in the working state. The dividing plate 34 in the C-shaped connecting support 33 drives the soil cutting blade 36 to rotate, contacts and cuts the land, so that the soil at the ditching position is loosened, which creates favorable conditions for the subsequent ditching operation.

[0072] 5.4 Furrowing and soil conditioning

[0073] The furrowing member 24 is inserted into the loosened soil and moves within the soil as the drive device moves, thereby performing the actual furrowing operation. The intermediate spring rod 26 provides the necessary cushioning during this process, ensuring smooth furrowing. At the same time, the inwardly converging inner vertical fixing plate 21 is inserted into the furrow and converges the soil within the furrow as the drive device moves. The cooperation of the flat inner vertical fixing plate 20 ensures that the inner side of the furrow is kept neat. In addition, the inwardly converging outer vertical fixing plate 17 and the flat outer vertical fixing plate 16, in cooperation with the inwardly converging horizontal fixing plate 19 and the flat horizontal fixing plate 18, neatly arrange the soil converged during the furrowing process, avoiding the scattering of soil and affecting the operation effect.

[0074] 5.5 Furrowing depth adjustment

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

[0076] It will be obvious to a person skilled in the art that, without departing from the spirit or essential characteristics of the application, the present application can be implemented in other specific forms. The present examples are therefore to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the description given above, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims.
