Description

Technical Field

[0001] The utility model specifically relates to a drilling and supporting integrated device for planting kudzu vine. Background Art

[0002] Pueraria lobata, also known as kudzu root, is a plant with a long history of medicinal and edible use. During the cultivation of Pueraria lobata, it prefers a warm and humid climate, is heat-resistant but not cold-resistant, and has a suitable growth temperature of about 20-30℃. Sufficient light is conducive to its photosynthesis and nutrient accumulation. When developing Pueraria lobata cultivation, we should strictly follow the relevant regulations and standards for green food production, establish a standardized cultivation base, and produce natural, safe, and nutritious Pueraria green food raw materials. The high-yield cultivation land is fully deep-turned and ridged, with a ridge height of 15-20cm and a ridge width of 80-100cm, which is conducive to drainage. Pueraria lobata is a shallow-rooted woody vine, and its root system is mainly distributed in the soil layer of about 100cm. Therefore, it will be planted in trenches and holes. No matter it is trench planting or hole planting, the seedlings must be planted deeply and buried shallowly. When planting the seedlings, wet the roots of the seedlings with water, and put the seedlings into the pit after they are wet, so that the roots can spread naturally, fill the soil, and gently lift the seedlings upwards so that the seedlings are exposed to the soil surface appropriately. Then, tamp the backfill soil, water enough to fix the roots, and cover the topsoil in time after the water seeps down. The topsoil is generally 4-5cm. Pueraria lobata can be planted in autumn or spring. Planting in autumn needs to be planted before the soil freezes, and planting in spring should be early to prevent the spring warming from being too fast, the root system has not yet recovered, the leaves have been unfolded, and the transpiration is too large, which affects the survival rate. You can choose pure varieties, free of diseases and insect pests, full buds, and no mechanical damage as the source of Pueraria lobata. In the above process, deep planting and shallow burial are difficult and need to rely on pure manual operation. There are no special tools for quantitative and standardized digging and drilling operations, which limits the development of large-scale planting. Utility Model Content

The support rod 7-1 and the linear slide 7-5 are arranged vertically side by side. A slider 7-2 is provided on the support rod 7-1. A slider groove 7-2-1 is machined in the slider 7-2 along its height direction. The slider 7-2 is sleeved on the support rod 7-1 through the slider groove 7-2-1. A fixing rod 7-8 is provided between the slider 7-2 and the linear slide 7-5. One end of the fixing rod 7-8 is fixedly connected to the slider 7-2, and the other end of the fixing rod 7-8 is fixedly connected to the slide table in the linear slide 7-5. The slider 7-2 makes a reciprocating sliding motion along the length direction of the support rod 7-1 driven by the slide table in the linear slide 7-5. The horizontal plate 7-9 is arranged horizontally. The top surface of the horizontal plate 7-9 is connected to the bottom of the support member 6. A first soil expansion claw 7-6 and a second soil expansion claw 7-7 are arranged in cooperation below the horizontal plate 7-9. The upper end of the first soil expansion claw 7-6 is hinged to one end of the horizontal plate 7-9, and the upper end of the second soil expansion claw 7-7 is hinged to the other end of the horizontal plate 7-9. A circular hole 7-9-1 is machined in the horizontal plate 7-9 along its plate thickness direction. The support rod 7-1, the linear slide 7-5 and the material conveying pipe 6-8 pass through the circular hole 7-9-1 and are arranged between the first soil expansion claw 7-6 and the second soil expansion claw 7-7.

[0063] In this embodiment, a first support ear 8-1 and a second support ear 8-2 are respectively arranged on the inner walls of the first soil expansion claw 7-6 and the second soil expansion claw 7-7. One end of the first support ear 8-1 is fixedly connected to the inner wall of the first soil expansion claw 7-6, and one end of the second support ear 8-2 is fixedly connected to the inner wall of the second soil expansion claw 7-7. Third support ears 8-3 and fourth support ears 8-4 are respectively fixedly connected to both sides of the slider 7-2. A first connecting rod 7-3 is arranged between the third support ear 8-3 and the first support ear 8-1, and a second connecting rod 7-4 is arranged between the fourth support ear 8-4 and the second support ear 8-2. One end of the first connecting rod 7-3 is hinged to the third support ear 8-3, and the other end of the first connecting rod 7-3 is hinged to the first support ear 8-1. One end of the second connecting rod 7-4 is hinged to the fourth support ear 8-4, and the other end of the second connecting rod 7-4 is hinged to the second support ear 8-2.

[0064] Furthermore, when the included angle between the first connecting rod 7-3 and the slider 7-2 is acute, the first soil expansion claw 7-6 and the second soil expansion claw 7-7 are in a closed and abutted state. When the included angle between the second connecting rod 7-4 and the slider 7-2 is obtuse, the first soil expansion claw 7-6 and the second soil expansion claw 7-7 are in a separated and expanded state.

[0065] Further, when the slide in the linear slide 7-5 drives the slider 7-2 to move upward in the support rod 7-1 through the fixed rod 7-8, the slider 7-2 drives the first soil-expanding claw 7-6 and the second soil-expanding claw 7-7 to be in a contracted state through the first connecting rod 7-3 and the second connecting rod 7-4; when the slide in the linear slide 7-5 drives the slider 7-2 to move downward in the support rod 7-1 through the fixed rod 7-8, the slider 7-2 drives the first soil-expanding claw 7-6 and the second soil-expanding claw 7-7 to be in an expanded state through the first connecting rod 7-3 and the second connecting rod 7-4.

[0066] Further, a circular hole 7-9-1 is machined in the horizontal plate 7-9 to ensure that the support rod 7-1, the linear slide 7-5, and the material conveying pipe 6-8 can cooperate with the soil-expanding claws.

[0067] Further, while the support sleeve 6-3 and the soil-digging member 7 make a downward movement driven by the first connecting assembly 6-4 and the second connecting assembly 6-5, when the soil-expanding claws are in an expanded state, it can ensure that the soil layer is in a loose state. The slider 7-2 drives the soil-expanding claws to also make a downward movement, ensuring that when the soil-expanding claws first expand the soil, the seeds in the material conveying pipe 6-8 are then inserted into the loose soil through the pipeline. The pipeline will stop descending when it is inserted about 5 cm into the soil, and the seeds will fall into the soil. Finally, while the support sleeve 6-3 and the soil-digging member 7 make an upward movement driven by the first connecting assembly 6-4 and the second connecting assembly 6-5, the slider 7-2 drives the soil-expanding claws to also make an upward movement, returning to the initial state, thus realizing the standardized unity of the operating action postures of the continuous operation links of soil digging, soil expansion, and seed dropping during the planting process.
