Technical Field

[0001] This invention belongs to the field of agricultural machinery technology and provides a sweet potato planting device that is suitable for clay soil, automatically plants and covers soil, and reduces labor intensity. Background Technology

[0002] Vertical planting of sweet potato seedlings results in limited space for tuber formation, leading to overcrowding, low yields, and a high incidence of deformed tubers. Horizontal planting, on the other hand, provides more space for tuber formation and more even nutrient absorption. To reduce farmers' labor intensity, various types of sweet potato seedling transplanting machinery have emerged on the market. Chinese Patent 2022101630277 discloses a sweet potato seedling transplanting device and machine, which reduces farmers' labor intensity to some extent. However, in actual use, the transplanting drive mechanism is prone to damaging or breaking seedlings, especially in clay soil, and the overall structure is complex. In clay soil, manual inspection and soil covering are required later. Summary of the Invention

[0005] To facilitate loading and unloading of the seedling clamping mechanism, in the above scheme, the seedling clamping mechanism fixing seat is further provided with a threaded hole, and a screw passing through the threaded hole fixes the seedling clamping mechanism fixing seat to the conveying mechanism.

The length of the guide limiting link 311 is greater than the width of the guide rail 4.

[0017] To facilitate loading and unloading of the seedling clamping mechanism 3, in the above embodiment, preferably, the seedling clamping mechanism fixing seat 301 is provided with a threaded hole 312, and the screw passing through the threaded hole 312 fixes the seedling clamping mechanism fixing seat 301 to the conveying mechanism 2.

[0018] To simplify and facilitate the manufacture of the conveying mechanism 2, in the above embodiment, preferably: the conveying mechanism 2 includes a drive sprocket 201 rotatably connected to the support frame 1, and a chain 202 meshing with the drive sprocket 201; the seedling clamping mechanism 3 is fixed at equal intervals on the chain 202.

[0019] To ensure the transmission stability of the transmission mechanism 2, in the above embodiment, preferably, the chain 202 consists of two chains, which are installed side by side on the drive sprocket 201.

[0020] To simplify the structure of the support frame 1, in the above embodiment, preferably: the support frame 1 includes two L-shaped support beams 101, the two support beams 101 are fixedly connected as a whole by at least three longitudinal and transverse support beams 102, the support frame 1 has three sprocket mounting parts, each of which is equipped with a drive sprocket 201, and the shaft of at least one of the three drive sprockets 201 extends out of the support frame 1.

[0027] The sweet potato seedling planting process of the present invention is as follows: The entire device is installed on a tractor or a mobile cart. The output end of the external power is connected to the shaft of at least one of the three drive sprockets 201 through a coupling. The drive sprocket 201 drives the chain 202 for transmission. When the seedling clamping mechanism 3 moves to the guide rail 4 above the horizontal support beam 103 of the support frame 1, the guide rod 311 below the seedling clamping mechanism 3 is lifted, and the seedling baffle 304 opens. At this time, the seedling is manually placed in. After the seedling clamping mechanism 3 slides out of the guide rail 4, the seedling baffle 304 of the seedling clamping mechanism 3 closes to prevent the seedling from falling out. When the seedling clamping mechanism 3 inserts its seedling baffle 304 into the ground and digs a small pit, it moves while simultaneously opening the seedling baffle 304, causing the seedlings to fall into the pit, thus achieving the purpose of planting seedlings. Because clay covers the seedling baffle 304 as it is inserted and the pit is dug, and due to the combined motion of the tractor or moving trolley moving forward and the seedling baffle 304 moving backward, the clay on the seedling baffle 304 falls into the dug pit, automatically covering the seedlings with soil. The entire process achieves automatic planting and automatic soil covering, especially suitable for clay soil, eliminating the need for additional soil covering checks and operations, effectively reducing labor intensity. Furthermore, the same seedling clamping mechanism 3 achieves automatic planting and automatic soil covering without requiring external power, effectively simplifying the structure of the entire sweet potato transplanter and reducing manufacturing and maintenance costs. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
