[0024] See also Figure 2-3 In order to prevent corn from colliding during its growth and affecting its output, the adjusting mechanism 3 in this embodiment includes a first motor 301 fixed on the front side of the mounting plate 2. The output shaft of the first motor 301 penetrates and extends to the inside of the mounting plate 2 and is fixed with a first threaded rod 302. The output shaft of the first motor 301 drives the first threaded rod 302 to rotate. The other end of the first threaded rod 302 is rotatably connected to the rear inner wall of the mounting plate 2 through a bearing. The outer side of the first threaded rod 302 is threadedly connected with a threaded block 303. The first threaded rod 302 drives the threaded block 303 to rotate.

A storage tank 306 is fixed on the inner side of the mounting hole 305. The support plate 304 drives the storage tank 306 to move, so that the spacing of corn planting can be adjusted. A soil turning assembly is provided on the upper surface of the support plate 304. A second motor 307 is fixed on the upper surface of the storage tank 306. The output shaft of the second motor 307 passes through and extends to the interior of the storage tank 306, and a rotating rod 308 is fixed. The output shaft of the second motor 307 drives the rotating rod 308 to rotate. The bottom end of the storage tank 306 is connected to a discharge pipe 309. The bottom end of the rotating rod 308 passes through and extends to the interior of the storage tank 306, and a rotating blade 310 is fixed on the outside. The rotating rod 308 drives the rotating blade 310 to rotate, so that the corn seeds move from the storage tank 306 to the discharge pipe 309, and are quantitatively put into the soil. After the corn seeds are put into the soil.

[0025] In this example, two threads in opposite directions are distributed on the outer side of the first threaded rod 302 and are symmetrically distributed front to back about the central axis of the first threaded rod 302.

[0027] See also Figure 4 In order to bury the corn seeds in the soil, the flattening mechanism 4 in this embodiment includes a fixing plate 401 fixed to the lower surface of the bottom plate 1, a mounting opening 402 is provided on the front of the fixing plate 401, a sliding rod 403 is fixed between the inner top wall and the inner bottom wall of the mounting opening 402, a sliding block 404 is slidably connected to the outer side of the sliding rod 403, a spring 405 is fixed between the upper surface of the sliding block 404 and the inner top wall of the mounting opening 402, and when the sliding block 404 slides on the sliding rod 403, the spring 405 is compressed, so that the spring 405 is elastic. Force is applied to the slider 404, and the back side of the slider 404 is rotatably connected to the rotating shaft 406 through a bearing, and a soil pressing roller 407 is fixed to the outside of the rotating shaft 406. After the corn seeds are put into the soil, the soil pressing roller 407 passes from the rear, turns over the soil by the soil turning rod 313 and presses it back into the pit, so that the soil covers the corn seeds and allows the corn seeds to take root quickly. The spring 405 can apply elastic force to the slider 404 to keep the soil pressing roller 407 in contact with the ground, thereby avoiding the inability to flatten the turned-up soil when there is a pit or a soil bag, which affects the growth of corn.

[0028] In this example, there are two fixed plates 401 , which are symmetrically distributed front and back about the central axis of the bottom plate 1 , so that the soil pressing roller 407 remains stable during rotation.

[0029] The working principle of the above embodiment is:

[0030] (1) First, calculate the appropriate planting spacing according to the area of ​​the planting site and the space required for the corn to mature, then turn on the first motor 301, the output shaft of the first motor 301 drives the first threaded rod 302 to rotate, the first threaded rod 302 drives the threaded block 303 to rotate, the threaded block 303 drives the support plate 304 to move, the support plate 304 drives the storage tank 306 to move, so that the spacing of corn planting can be adjusted, and then move the equipment to the planting site, turn the handle 312, the handle 312 drives the second threaded rod 311 to rotate, so that the second threaded rod 311 rotates and moves on the support plate 304, the second threaded rod 311 moves and drives the tiller rod 313 to move, so that the tiller rod 313 is inserted into the soil at a suitable depth.

[0031] (2) The device is pushed by the handle 5 to move the device on the planting ground. The soil turning rod 313 turns up the soil on the planting ground so that the corn seeds can enter the soil. At this time, the second motor 307 is turned on, and the output shaft of the second motor 307 drives the rotating rod 308 to rotate. The rotating rod 308 drives the rotating blade 310 to rotate, so that the corn seeds are moved from the storage tank 306 to the discharge pipe 309 and are quantitatively delivered to the soil. After the corn seeds are delivered to the soil, the soil pressing roller 407 passes from the rear and turns up the soil turned up by the soil turning rod 313 and presses it back into the pit, so that the soil covers the corn seeds and allows the corn seeds to take root quickly. The spring 405 can apply elastic force to the slider 404 to keep the soil pressing roller 407 in contact with the ground, thereby avoiding the inability to flatten the turned-up soil when there is a pit or a mound, which affects the growth of corn.
