Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a pneumatically pressed seedling planting device. Background Art

[0002] Saplings are also referred to as seedlings, which are a general term for various fruit tree seedlings, tree seedlings, and shrub seedlings. Saplings: Saplings with roots and stems. All saplings cultivated in nurseries, regardless of age, are called saplings before they are planted. After the saplings are planted, they need to be planted in the ground before they can grow into big trees. The traditional method of planting saplings is manual planting, which requires digging holes, planting, and filling soil, which is a lot of work. With the development of agricultural machinery, sapling planting devices have emerged to replace manual planting, greatly reducing the workload of workers. Most of the existing sapling planting devices are walking type, and a spiral shaft perpendicular to the body is set on the walking vehicle body. The spiral shaft is rotated to open a hole, and then the hole is planted by a planting mechanism. The compaction mechanism compacts the soil.

However, the spiral shaft in the existing sapling planting device is perpendicular to the walking body, and the angle of the spiral shaft relative to the walking body is fixed, which can only be applied to planting on flat ground. When encountering sloping terrain, when the walking body climbs the slope, due to the tilt of the walking body front and back, the hole opened by the spiral shaft is not vertical.

[0030] Specifically, when the pneumatic extrusion-based sapling planting device in this embodiment is in use, the water tank 2 and the water pipe 3 are used to sprinkle water on the ground at the planting point to moisten the soil and loosen it, so as to facilitate the insertion of the planting shell 6 into the soil. A water pump can be arranged between the water pipe 3 and the water tank 2 to provide power for sprinkling water; the planting shell 6 is made of degradable material, which can provide nutrients for the growth of the plant after being degraded. When in use, the saplings need to be pre-loaded into the planting shell 6 (only the roots of the saplings are located in the planting shell 6), and then several planting shells 6 are placed in the sapling bin 4. The planting shell 6 is provided with through holes to ensure that the roots of the saplings can be When the saplings are loaded into the planting shell 6, soil is loaded into the planting shell 6 at the same time, so that the roots of the saplings can be supplied with soil. The bottom end of the planting shell 6 is set to be conical, which is convenient for inserting into the soil under pressure. After multiple planting shells 6 containing saplings are loaded into the seedling storage slide 5 (a loading port is set on the seedling bin 4, not shown in the drawings), multiple planting shells 6 are arranged one by one, and the flexible airbag 7 is inflated. The expansion of the flexible airbag 7 will push the planting shell 6 to move, and the planting shell 6 farthest from the flexible airbag 7 moves to the top of the seedling hole 8, falls and slides along the slide 9. Finally, it slides into the planting shell sleeve 11 at the bottom of the walking body 1. At this time, if the walking body 1 climbs the slope and tilts forward and backward, the sapling cannot be planted vertically, and the sapling angle adjustment device plays a role. The first driving mechanism drives the first shaft 10 to rotate, and the first shaft 10 drives the planting shell sleeve 11 and the planting shell 6 to rotate, and the planting shell 6 is adjusted to a vertical state. After the planting angle of the sapling is adjusted, it is necessary to adjust the cylinder 14 to be in line with the sapling and the planting shell 6 by pressing down the angle adjustment device, and the second shaft 13 is driven to move and rotate by the translation mechanism 12 and the second driving mechanism. The second rotating shaft 13 drives the cylinder 14 so that the cylinder 14 is in line with the sapling and the planting shell 6, which is convenient for pressing the planting shell 6 into the soil. The lower end of the cylinder 14 is connected with a pressing cylinder 15, and the pressing cylinder 15 is in the shape of a cylinder with an opening at the bottom. The edge of the bottom opening of the pressing cylinder 15 is directly pressed on the edge of the top opening of the planting shell 6 as the cylinder 14 is extended. The inner cavity of the pressing cylinder 15 is used to accommodate the trunk of the sapling to prevent the trunk of the sapling from being crushed. Through the extension of the cylinder 14, the planting shell 6 is pressed into the soil to complete the planting of a sapling. The walking body 1 moves forward to the next planting point to plant the next sapling.

[0031] In some embodiments, the planting shell 6 is provided with a soil sensor 16 and a communication chip 17, and a plurality of convex cameras 18 are evenly distributed around the top of the planting shell 6. The soil sensor 16 can detect soil pH value, temperature and other data, and the convex camera 18 can collect image information of the seedling. The convex camera is embedded in the top of the planting shell to prevent the planting shell from being damaged during the pressing process. To ensure that the convex camera can collect image information of the seedling, the top of the planting shell needs to be exposed to the ground. The communication chip 17 can send the soil pH value, temperature and other data detected by the soil sensor 16 and the image information of the seedling collected by the convex camera 18 to the service station, so as to analyze and judge the growth of the seedling. After the planting shell 6 is completely degraded, the soil sensor 16, the communication chip 17 and the convex camera 18 can be recycled. Please refer to the attached. Figure 5 In order to facilitate the recycling of the above-mentioned components, a metal shell 31 can be set, and the soil sensor 16 and the communication chip 17 are embedded in the metal shell 31. The line between the convex camera 18 and the communication chip 17 is set in the side wall of the planting shell 6. The side wall of the planting shell 6 is provided with a slot matching the metal shell 31. The metal shell 31 is inserted into the slot. A pull rope 32 is set on the metal shell 31. After the planting shell 6 is inserted into the soil, the pull rope 32 is exposed to the ground. After the planting shell 6 is completely degraded, the pull rope 32 is pulled to pull out the metal shell 31, and then the components are pulled out to complete the recycling.

The control system is respectively connected to the first drive mechanism, the second drive mechanism and the translation mechanism 12 signals. When the horizontal sensor 22 detects that the walking body 1 is tilted and the seedling cannot be planted vertically, the control system controls the first drive mechanism, the second drive mechanism and the translation mechanism 12 to adjust the angle of the seedling and the cylinder 14.
