Description

Technical Field

[0001] This utility model relates to the technical field of agricultural machinery, and in particular to a tobacco seedling planting tool. Background Technology

[0002] When planting tobacco seedlings, in order to reasonably control the planting density and provide a suitable growing environment, it is necessary to plant them at equal intervals as much as possible. However, in actual planting, measuring the distance in advance with measuring instruments such as tape measures will consume a lot of time and may affect the optimal planting period of tobacco seedlings, which is not suitable for tobacco seedling planting. On the other hand, if the distance is directly estimated by the staff without measuring the distance, it is very easy for the distance between tobacco seedlings to be too large, thus making the planting density unreasonable.

In this embodiment, both the driven cam 7 and the driven cam 8 are selected with one end being a large-radius arc end and the other end being a small-radius arc end, and the positions of the two small-radius arc ends are respectively located on the same side of the corresponding large-radius arc end, that is, when the small-radius arc end of the driven cam 7 is located above the large-radius arc end of the driven cam 7, the small-radius arc end of the driven cam 8 is located above the large-radius arc end of the driven cam 8. When the smaller radius arc end is above the larger radius arc end, the planting shovel 12 is at its highest point, and its lower end is above the lower horizontal section of the rolling wheel. When the smaller radius arc end is below the larger radius arc end, the planting shovel 12 is at its lowest point, and its lower end is below the lower horizontal section of the rolling wheel. This is the stage of digging planting holes.

[0060] In this embodiment, to facilitate the digging of planting holes by the planting shovel 12, the cutting edge of the lower end of the planting shovel 12 is located on the side of the lower end of the vertical plate of the L-shaped plate away from the seat 28. That is, the height of one side of the vertical plate of the L-shaped plate facing the seat 28 is greater than the height of the side of the vertical plate of the L-shaped plate away from the seat 28. To prevent the planting shovel 12 from separating from the seedling channel 4 during the up-and-down sliding process, a trapezoidal guide block protruding towards the seedling channel 4 is provided on the side of the planting shovel 12 that is in contact with the seedling channel 4. That is, the horizontal cross-section of the guide block is trapezoidal. A guide groove adapted to the guide block is provided on the side of the seedling channel 4 that is in contact with the planting shovel 12. The horizontal cross-section of the guide groove is also trapezoidal and arranged along the height direction. In this embodiment, for ease of installation, the lower end of the guide groove is open. At the same time, both the guide groove and the guide block are set as two sections and are arranged parallel to each other on both sides of the planting shovel 12.

[0061] Seedling section 3, such as Figure 5As shown, the system includes a rotating platform 13, a fixed platform 14, a seedling-seedling rotating shaft 15, a seedling-seedling incomplete gear 16, and a seedling-seedling driven gear 17. The seedling-seedling rotating shaft 15 is cylindrical. The rotating platform 13, the fixed platform 14, the seedling-seedling rotating shaft 15, and the seedling-seedling driven gear 17 are arranged coaxially. The rotating platform 13, the fixed platform 14, and the seedling-seedling driven gear 17 are arranged sequentially from top to bottom. The seedling-seedling rotating shaft 15 is arranged vertically, with its upper end fixedly connected to the rotating platform 13, its middle part passing through the fixed platform 14, and its lower end rotatably connected to the frame 1. The seedling-seedling driven gear 17 is fixedly connected to the seedling-seedling rotating shaft 15. The seedling-seedling incomplete gear 16 and the seedling-seedling driven gear 17 mesh with each other to form an intermittent motion mechanism. The fixed platform 14 is fixedly connected to the frame 1. Multiple seedling buckets 18 are cylindrical structures, arranged on the rotating platform 13, and together with the fixed platform 14, form a complete bucket-shaped structure. The lower opening of the seedling bucket 18 is opened on the fixed platform 14. To increase the stability of the seedling division section 3, two support plates are provided, installed parallel to each other on both sides of the seedling division rotating shaft 15. To increase the stability of the rotating platform 13, a cylinder extends downward from the bottom of the fixed platform 14 and is fitted onto the seedling division rotating shaft 15. The inner diameter of the cylinder is the same as the outer diameter of the seedling division rotating shaft 15. The seedling division rotating shaft 15 is cylindrical, and a rotating seat is provided at a corresponding position on the upper surface of the lower mounting plate. The lower end of the seedling division rotating shaft 15 is installed in the rotating seat, realizing the rotatable connection between the lower end of the seedling division rotating shaft 15 and the lower mounting plate. A rotating shaft is rotatably installed on the axis of rotation of the seedling incomplete gear 16. The rotating shaft is arranged vertically, with its upper end rotatably connected to the seedling incomplete gear 16 and its lower end fixedly installed on the upper surface of the lower mounting plate. Meanwhile, in order to keep the incomplete seedling gear 16 and the seedling driven gear 17 meshed during the transmission process, a waist-shaped plate is connected to the upper side of the incomplete seedling gear 16 and the seedling driven gear 17. One end of the waist-shaped plate is fixedly connected to the upper end of the rotating shaft, and the other end is rotatably connected to the seedling rotating shaft 15.

[0062] In this embodiment, in order to achieve the effect of rotating one seedling bucket 18 unit at a time, i.e., rotating 60°, when the seedling section 3 rotates, the seedling incomplete gear 16 only has a portion of the teeth, i.e., only 1 / 6 of the teeth. The seedling incomplete gear 16 and the seedling driven gear 17 constitute an intermittent motion mechanism. That is, when the seedling incomplete gear 16 rotates one revolution, the seedling driven gear 17 rotates 1 / 6 revolution, i.e., 60°. At this time, the seedling bucket 18 rotates one unit, and the next seedling bucket 18 containing tobacco seedlings rotates to the opening of the fixed platform 14, so that the tobacco seedlings enter the seedling channel 4 from the opening.

[0063] Transmission parts, such as Figure 4As shown, it includes a driving gear 19, a driven gear 20, a cavity-opening driving bevel gear 21, and a cavity-opening driven bevel gear 22; the driving gear 19 is fixedly mounted on the rotating shaft of the moving part 5; the driving gear 19 and the driven gear 20 mesh with each other; the driven gear 20 and the cavity-opening driving bevel gear 21 are coaxially fixedly connected and rotate synchronously, and are rotatably connected to the frame 1; the cavity-opening driven bevel gear 22 and the cavity-opening driving bevel gear 21 mesh with each other; the cavity-opening driven bevel gear 22 and the cavity-opening driving sprocket 9 are coaxially fixedly connected and rotate synchronously.

[0064] The transmission unit also includes a seedling-seedling drive sprocket 23, a seedling-seedling driven sprocket 24, a seedling-seedling chain 25, a seedling-seedling drive bevel gear 26, and a seedling-seedling driven bevel gear 27; the seedling-seedling drive sprocket 23 and the driven gear 20 are coaxially fixedly connected and rotate synchronously; the seedling-seedling driven sprocket 24 and the seedling-seedling drive bevel gear 26 are coaxially fixedly connected and rotate synchronously, and are rotatably connected to the frame 1; the seedling-seedling chain 25 is wound around the seedling-seedling drive sprocket 23 and the seedling-seedling driven sprocket 24; the seedling-seedling drive bevel gear 26 and the seedling-seedling driven bevel gear 27 mesh with each other; the seedling-seedling driven bevel gear 27 and the seedling incomplete gear 16 are coaxially fixedly connected and rotate synchronously, and are rotatably connected to the frame 1.

[0065] The transmission ratio of the driving gear 19 and the driven gear 20 can be determined according to the actual planting conditions, that is, by changing the driving gear 19 and the driven gear 20 with different parameters. In this embodiment, the transmission ratio of the driving gear 19 and the driven gear 20 is selected to be 1 / 3, that is, when the rolling wheel rotates three times, the driving gear 19 rotates three times and the driven gear 20 rotates one time. At this time, the seedling division section 3 rotates one seedling bucket 18 unit, and the hole-opening shovel 12 completes one stroke, completing the planting of one tobacco seedling. The interval between two adjacent tobacco seedlings is three times the circumference of the rolling wheel.

[0066] To facilitate operation, the seedling section 2 has an inclined panel; the inclined panel is located on one side of the seat 28, which is lower than the other side. To prevent the tobacco seedlings from falling out of the seedling section 2 during planting, a baffle is installed around the seedling section 2.

[0067] To facilitate the detachable connection between the device provided in this embodiment and the external moving device, two support bars extend upward from the side of the lower mounting plate facing the external moving device. At the same time, a connecting bar extends from the side of the support bars facing the external moving device. A connecting hole is provided at the end of the connecting bar, and the external moving device can be detachably and rotatably connected to the device provided in this embodiment through the connecting hole.

[0068] To ensure the stability of seat 28, two sets of support bars extend upward from the lower mounting plate. Each set of support bars has two support bars with an included angle, and their lower ends are fixed at the same point. The support bar on the side of the external moving device is placed vertically, while the other support bar moves from bottom to top in a direction away from the external moving device. A reinforcing bar extends horizontally from the side of the vertically placed support bar toward the external moving device, and the other end of the reinforcing bar is fixedly connected to the support plate.

[0069] To reduce subsequent workload, a soil accumulation unit is provided at the lower end of the seedling channel 4 on the side away from the planting shovel 12. In this embodiment, the soil accumulation unit consists of two plates that are close to each other along the direction away from the seedling channel 4, which are used to contain soil and bury the roots of the tobacco seedlings in the soil.

[0070] The specific implementation method is as follows: The operator sits on seat 28 and manually separates the tobacco seedlings into the seedling bucket 18. When the external moving device moves forward, the device provided in this embodiment moves accordingly, and the rolling wheel rotates. Every time the rolling wheel rotates three times, the driving gear 19 rotates three times and the driven gear 20 rotates one time. At this time, the seedling separation part 3 rotates one seedling bucket 18 unit, and a tobacco seedling is delivered into the seedling channel 4. The planting shovel 12 completes one stroke, completing the planting of one tobacco seedling. Specifically, when the planting shovel 12 is digging the planting hole, there is always one seedling bucket 18 aligned with the opening on the fixed platform 14, so that there is always a tobacco seedling in the seedling channel 4 moving towards the planting hole until the roots of the tobacco seedling are placed in the planting hole. The soil accumulation unit then buries the roots of the tobacco seedling in the soil, ultimately achieving equidistant planting of tobacco seedlings.

For those skilled in the art, any equivalent modifications or substitutions to the utility model are also within the scope of the utility model. Therefore, all equivalent transformations, modifications, and improvements made without departing from the spirit and principles of the utility model should be covered within the scope of the utility model.
