[0002] Tobacco seedling automatic transplanting machine is common mechanical equipment for tobacco seedling transplanting, which can adjust planting plant distance according to the "wide row narrow plant" density requirement during tobacco seedling transplanting. Meanwhile, it can also adjust the depth of tobacco seedling planting according to the height of tobacco ridge and the requirement of deep planting, to ensure that the core leaves of tobacco seedlings do not protrude from the mulch and are not covered by soil. In addition, the automatic transplanting machine can also flexibly adjust the direction in hilly tobacco area to ensure that tobacco seedlings are planted in the center of the land ridge. On this basis, the relevant inventors further enriched the functions of tobacco seedling transplanting machine. For example, the tobacco seedling transplanting machine disclosed in Chinese patent "Tobacco seedling planting and ponding transplanting machine" (application number: 2021102521728) can realize automatic hole digging and tobacco seedling transplanting, and also can realize a series of operations such as ponding, fertilization and watering, which can further reduce labor intensity.

[0020] The application will be further explained and described below in combination with examples. Embodiment

[0021] As shown in Figure 1 , Figure 2 , the semi-automatic tobacco seedling transplanting device provided by the application comprises a walking frame provided with a placing plate 2, a lifting mechanism, a tobacco seedling placing frame 5, and a punching mechanism.

[0022] The walking frame is composed of two walking wheels 1 (connected by a bearing between the two walking wheels) and the placing plate 2 arranged between the two walking wheels 1, and a seedling taking passage 4 is designed in the middle of the placing plate 2.

[0023] The lifting mechanism is connected and fixed to one side of the placing plate 2, and the structure thereof comprises two vertical fixed plates 8 and a first cylinder 9 which can be displaced up and down and is fixed between the two vertical fixed plates 8; the output end top of the first cylinder 9 is provided with a rotating wheel 10, and the top of the vertical fixed plate 8 on the inner side of the placing plate 2 (i.e. the middle direction of the placing plate 2) is provided with a guide wheel 12.

[0024] One end of a lifting rope 11 passes through the top of the vertical fixed plate on the outer side of the placing plate 2 (referring to the existing conventional design, the vertical fixed plate on the outer side of the placing plate 2 is designed with a lifting rope recovery rotating wheel), and then passes through the rotating wheel 10 and the guide wheel 12 in sequence and is connected with a seedling taking clamp 3 downward (referring to the existing conventional design, the seedling taking clamp 3 can adopt a conventional clamping jaw which can be loosened and tightened or a mechanical hand which can be opened and closed);

[0025] The tobacco seedling placing frame 5 comprises a vertical plate 18 vertically fixed on the placing plate 2 and a horizontal plate 19 extending horizontally and perpendicularly to the inner side of the placing plate 2, and the horizontal plate 19 is designed with a second motor 20 at the end thereof, and the output end of the second motor 20 is further connected with a seedling placing disc 6.

[0026] The punching mechanism comprises a sliding frame 15, the second cylinder 16 on the sliding frame 15, and a power mechanism for controlling the lateral movement of the sliding frame 15;

[0027] The sliding frame 15 is a "horizontal fold" support connected by a horizontal plate and a vertical plate. The vertical plate can slide along the sliding groove (not shown in the figure, a conventional design can be used) provided on the placement plate 2. The end of the horizontal plate is provided with the second cylinder 16 perpendicular to the direction of the horizontal plate (the second cylinder 16 is located below the horizontal plate 19 to reduce the space occupied by the entire device in the front-back and left-right directions). The output end of the second cylinder 16 is provided with a drill shaft 17 for digging seedling planting holes (the drill shaft 17 is finally driven by the second cylinder 16 to move longitudinally to complete the hole digging).

[0028] The power mechanism comprises a first motor 13 and a screw rod 14 connected to the rotor of the first motor 13. The first motor 13 can be placed inside the vertical plate 18 to save space. The screw rod 14 is arranged in the lateral and vertical direction of the vertical plate of the sliding frame 15 (the screw rod 14 is screwed with the sliding frame 15 through the threaded hole provided on the vertical plate), so that the sliding frame 15 is moved laterally by the rotation of the first motor 13, and the drill shaft 17 is finally adjusted in the lateral direction of the hole digging position.

[0029] The seedling placing plate 6 is a rotatable flat plate controlled by a second motor 20. The edge of the flat plate is provided with evenly distributed seedling clamping hands 7 for clamping tobacco seedlings (referring to the existing conventional design, the seedling clamping hands 7 can also use conventional clamping jaws or mechanical hands that can be opened and closed). According to the preset program and speed, when the tobacco seedlings clamped by the seedling clamping hands 7 are rotated to above the seedling clamping hands 3, the seedling clamping hands 7 will be loosened, and at the same time, the seedling clamping hands 3 will be put into the rising seedling clamping hands 3.

[0030] In actual design, the first cylinder 9, the second cylinder 16, the first motor 13, the second motor 20, the seedling clamping hands 7 and the seedling clamping hands 3 are controlled and adjusted by the control box 21 based on the preset program. The control box 21 can be arranged inside the vertical plate 18 facing the placement plate 2 to reduce the overall volume of the device.

[0031] The main idea of the device provided in the present application is to realize the automatic operation of tobacco seedling transplanting by the alternating up-and-down movement of the lifting mechanism and the drilling mechanism, and the orderly connection and placement of the tobacco seedlings. In specific operation, the lifting mechanism drives the seedling clamping hands 3 to move up to below the seedling clamping hands 7 to obtain the tobacco seedlings, and at the same time, the sliding frame 15 in the punching mechanism adjusts the drill shaft 17 to below the seedling clamping hands 3 by the lateral movement of the screw rod 14 and further vertically punches a hole by the driving of the second cylinder 16. Then, with the movement of the walking frame, the drill shaft 17 moves laterally back, and the seedling clamping hands 3 place the tobacco seedlings in the punched hole through the seedling channel 4 to complete the tobacco seedling transplanting and planting.

[0032] Overall, the relevant component layout structure is compact, the internal space utilization rate of the device is high, the occupied space of the whole device can be greatly reduced, which is not only beneficial to the nursing management of the whole device by the operating personnel, but also helps the transplanting operation of tobacco seedlings in different operation sites, especially in small-range operation space sites, thereby reducing the labor operation cost.
