For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0022] Such as Figures 1 to 4As shown in the figure, the frame structure of the manual seedling transplanting machine for tobacco in hilly and mountainous areas in this embodiment includes a chassis 1. At the upper end of the chassis 1, a power device 2 is installed. The power device 2 is composed of components such as an engine and is used to drive the tobacco transplanting machine. At the upper end of the chassis 1 on one side of the power device 2, a support plate 3 is installed. At the upper end of the support plate 3, a seedling feeding disk 4 is rotatably connected. A number of storage tubes 1 are installed in a circumferential array at the upper end of the seedling feeding disk 4. The storage tubes 1 are used to place the transplanted tobacco. At the lower end of the support plate 3 below the seedling feeding disk 4, a seedling feeding device 6 is installed. The seedling feeding device 6 is used to drive the seedling feeding disk 4 to rotate and perform seedling dropping, so as to realize the planting of tobacco. The working principle of the seedling feeding device 6 is a prior art means in the technical field of transplanting machines, so no more description will be given here. At the upper end of the support plate 3 on one side of the seedling feeding disk 4, a support rod 7 is installed. At the upper end of the support rod 7, a mounting plate 8 is installed. An automatic seedling replenishing mechanism is installed at the upper end of the mounting plate 8 through a connecting rod. The automatic seedling replenishing mechanism is used to put tobacco into the storage tube 1 that is about to drop seedlings and place tobacco, so as to avoid the need for manual seedling replenishment in the later stage.

[0023] Specifically, the automatic seedling replenishing mechanism includes a motor 901, a material tray 902, a placement tube 903, a detector 904, a controller 905, and a fixed disk 906. At the upper end of the mounting plate 8, a fixed disk 906 is installed through a connecting rod. At the lower end of the mounting plate 8, a motor 901 is installed. The output end of the motor 901 passes through the connecting rod and a material tray 902 is installed above the fixed disk 906. A number of placement tubes 903 are installed at the upper end of the material tray 902. Through holes 10 are arranged in a distributed manner through the upper end of the material tray 902 inside the placement tube 903. Below one through hole 10, a detector 904 is installed. At the front end of the mounting plate 8, a controller 905 is installed. By using the detector 904 to detect whether there is tobacco in the storage tube 1 that is about to drop seedlings, when it is necessary to replenish seedlings for tobacco, the motor 901 controls the material tray 902 to rotate a certain angle, and the seedlings inside the placement tube 903 fall into the storage tube 1 through the through hole 10, realizing the automatic seedling replenishment of the storage tube 1, avoiding the situation that there is no tobacco in the storage tube 1 resulting in gaps in land planting and the need for manual seedling replenishment in the future. The detector 904 is an infrared sensor. The principle of the infrared sensor detecting whether an object exists is a known prior art, so no more description will be given here, and it is used to detect whether there is tobacco in the storage tube 1.

[0024] Furthermore, a blanking tube 11 is installed on the fixed disk 906 below one through hole 10 through a mounting hole. The number of detectors 904 is two, and the detectors 904 are symmetrically installed at the lower end of the blanking tube 11. The blanking tube 11 is used to guide the tobacco, facilitating the tobacco to enter the storage tube 1. And the number of detectors 904 is two. Only when both detectors 904 detect that there is no tobacco in the storage tube 1, the motor 901 will drive the material tray 902 to rotate.

[0025] Further, the blanking pipe 11 is located directly above the first storage pipe 5 adjacent to the seedling outlet of the seedling feeding tray 4. The position of the blanking pipe 11 corresponds to the first storage pipe 5 adjacent to the seedling dropping position of the seedling feeding tray 4, and is used to detect the first storage pipe 5 where seedlings are about to drop.

[0026] Further, the material discharging holes 10 are all arranged in a circular array on the material tray 902. The number of the placing pipes 903 is one less than the number of the material discharging holes 10. When not in use, the material discharging holes 10 without the placing pipes 903 installed are aligned with the blanking pipe 11.

[0027] Furthermore, a vertical rod 12 is installed at the upper end of the support plate 3 on one side of the seedling feeding tray 4. An adjusting ring 13 is movably installed on the surface of the vertical rod 12. A fixing bolt 14 is installed on the surface of the adjusting ring 13 through a threaded hole. One end of the fixing bolt 14 extends to the surface of the vertical rod 12. A supporting plate 15 is adjusted on the surface of the vertical rod 12 above the adjusting ring 13. By adjusting the height of the adjusting ring 13 on the vertical rod 12 and using the fixing bolt 14 to fix the position of the adjusting ring 13, the height of the supporting plate 15 can be adjusted, so that tobacco can be placed without manual loading and is convenient to adjust according to the height of the user, which is convenient to use.

[0028] The usage method of this embodiment is as follows: Before use, the planter puts the tobacco into the first storage pipe 5 and the placing pipe 903 respectively, and at the same time aligns the material discharging holes 10 without the placing pipes 903 installed with the blanking pipe 11. When in use, the planter puts the tobacco into the first storage pipe 5. Under the action of the seedling feeding device 6, the tobacco in the first storage pipe 5 drops, realizing the transplanting of the tobacco. At the same time, the worker puts the tobacco into the empty first storage pipe 5. During this process, the detector 904 detects whether there is tobacco in the first storage pipe 5 adjacent to the seedling dropping port of the seedling feeding tray 4. When tobacco needs to be replanted, the motor 901 controls the material tray 902 to rotate a certain angle, and the seedlings in the placing pipe 903 fall into the first storage pipe 5 through the material discharging holes 10, realizing the automatic replanting of the first storage pipe 5. During the replanting process by the planter, the empty placing pipe 903 is also replenished at the same time. After each placing pipe 903 contacts the blanking pipe 11 after the material tray 902 rotates, the material tray 902 automatically returns to the initial position, and then the detector 904 continues to perform the detection work, continuously detecting whether replanting is required.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
