[0018] The mobile lifting mechanism includes a bottom plate 8 located below the cylindrical material storage shell 2, multiple groups of walking wheels 12 arranged below the bottom plate 8, two control rods 13 connected to one side of the bottom plate 8 and arranged at intervals, a handle 14 connected to the top of one side of the control rod 13, a group of electric push rods 11 respectively installed at both ends of the upper side of the bottom plate 8, a mounting plate 10 connected to the output end of a group of electric push rods 11 and connected to the bottom of one end of the cylindrical material storage shell 2, and an opening 9 arranged on the upper side of the bottom plate 8 and located between the two groups of electric push rods 11. A group of electric push rods 11 is provided with two, and multiple material discharge barrels 5 can pass through the opening 9 and extend to the bottom of the bottom plate 8; when the mobile lifting mechanism drives multiple material discharge barrels 5 to enter the planting pit, the two groups of electric push rods 11 are started to drive the cylindrical material storage shell 2 connected to the two mounting plates 10 to descend, and drive multiple material discharge barrels 5 connected thereto to enter the planting pit.

[0019] The upper side of the first L-shaped bracket 15 is connected to a power supply housing 29 connected to one side of the rectangular material storage shell 1, and a battery 30 is arranged inside the power supply housing 29; the battery 30 provides the required power support for the device to perform sowing operations in outdoor fields.

[0021] A controller electrically connected to the electric push rod 11 , the first stepping motor 18 and the second stepping motor 25 is disposed on the operating rod.

[0022] Working principle: When sowing corn seeds, first open the box cover 7, add the corn seeds into the planting box through the feeding port 6, and then push the planting machine to the planting pit position that has been dug in advance in the field. At this time, the two sets of electric push rods 11 are started by the controller to drive the cylindrical storage shell 2 connected to the two mounting plates 10 to descend, ensuring that the multiple lowering barrels 5 connected to the cylindrical storage shell 2 can extend into the planting pit. Among them, the lowering barrels 5 that do not match the spacing of the planting pits will be inserted into the soil. When the spacing between the planting pits is large, the first step is started by the controller. The feed motor 18 drives the inner rotating shaft 16 to rotate, thereby driving the multiple second connecting rods 23 connected thereto to rotate counterclockwise by 90 degrees. During this process, the arc-shaped opening 22 opened on the hollow rotating cylinder 21 ensures that the rotation is carried out without hindrance, so that the second arc-shaped sealing plate 24 connected to the second connecting rod 23 can open the corresponding discharge port 4, and the corn seeds in the cylindrical storage shell 2 enter the discharge barrel 5 through the discharge port 4 and finally fall into the planting pit. On the contrary, when the spacing between the planting pits is small, the first stepper motor 18 and the second stepper motor 23 are simultaneously started by the controller. The second stepper motor 25 and the first stepper motor 18 drive the inner shaft 16 to rotate ninety degrees clockwise, and the second stepper motor 25 drives the first shaft 26 to rotate, and the first gear 27 connected to the first shaft 26 drives the second gear 28 meshing with it to rotate, thereby driving the hollow drum 21 to rotate. This action makes the second arc-shaped sealing plate 24 and the first arc-shaped sealing plate 20 open all the discharge ports 4 at the same time to ensure that the corn seeds can fall into each corresponding planting pit. After the planting operation is completed, the two sets of electric push rods 11 are started again to The planting box is lifted to its original position, and the remaining soil in the lower barrel 5 falls due to gravity. Then, the planting machine can move to the next group of planting pits to continue to complete the sowing operation of the next batch of corn seeds. When facing the complex and changeable terrain conditions of the farmland, the planting machine can adjust the planting spacing to ensure that the corn seeds fall into the pre-dug, fixed-spacing planting pits, which not only improves the accuracy and efficiency of sowing, but also solves the problems of inaccurate sowing spacing and uneven sowing caused by shaking and tilting of traditional planters during travel.
