[0002] Direct seeding of rice is a cultivation method in which seeds are sown directly in dry fields without seedling raising or transplanting. It is also a form of mechanized rice planting. It has the characteristics of saving labor and costs, conserving water resources, saving land, reducing the labor intensity of rice growers, and having significant economic benefits. It is of great significance for realizing the light-weight, professional, large-scale and intensive development of rice production.
[0003] When using a dry direct seeding planter to plant rice, it is necessary to adjust the seeding rate to ensure a suitable planting density, adapt to different soil conditions, climate conditions, variety characteristics, and planting patterns, improve resource utilization efficiency, and ultimately achieve the goal of increasing yield and economic benefits.
[0004] However, when adjusting the seeding rate of rice in dry direct seeding machines, there are many different varieties of long-grain rice seeds, such as Guiyu 11, Yuzhenxiang, Xigong 6, Meixiangzhan 2, and Yunhui 290. These different varieties of long-grain rice seeds have different shapes and sizes. When faced with seeds of different shapes and sizes, the seed metering device in existing dry direct seeding machines needs to frequently change parts to meet the seeding requirements of different shapes and sizes. As a result, dry direct seeding machines cannot meet the seeding needs of different shapes and sizes, making them less applicable.
[0005] Therefore, how to design a dry direct seeding machine that can be adjusted according to the sowing needs of seed shape and size is a technical problem that technicians need to solve. Utility Model Content

[0045] Example 1
[0046] In this embodiment, to solve the problem that the seed metering device 103 is inconvenient for sowing seeds of different shapes and sizes, the technical solution of this embodiment is as follows, for reference. Figures 1 to 6The extrusion push plate 203 has an arc-shaped elastic curved surface structure, and the limiting baffle 202 is an L-shaped plate. The limiting baffle 202 is located at both ends of the extrusion push plate 203 and has a mirror-symmetrical structure. The pulling arc plate 204 has an arc-shaped elastic curved surface structure. The extrusion push plate 203 is connected to the adjusting frame 206 through the pulling arc plate 204. The outer wall of the threaded pressure plate 210 is in contact with the outer wall of the adjusting frame 206, driving the bevel gear 212 located at one end of the threaded rod 209. The bevel gear 212 meshes with the power bevel gear 213. By rotating the rotating bolt 214, the power bevel gear 213 is driven to rotate. The meshing between the driving bevel gear 212 and the power bevel gear 213 is utilized. The movement of the threaded pressure plate 210 causes it to slide outside the threaded rod 209. During the movement of the threaded pressure plate 210, the adjusting frame 206 moves, and under the action of the pulling arc plate 204, the pressing push plate 203 deforms, pushing the limiting baffle 202 outward, thereby adjusting the distance between the limiting baffles 202, and thus adjusting the capacity of the wheel groove 106. This allows for adjustment of the seed sowing amount to ensure a suitable planting density. At the same time, during the adjustment of the wheel groove 106, its size can be adjusted to accommodate seeds of different shapes and sizes, ensuring the applicability of the device.
[0047] As a further limitation of this technical solution, the guide slide plate 215 is an arc-shaped plate. The guide slide plate 215 is set on both sides of the limiting baffle 202 and has a mirror symmetrical structure. The shape of the guide slide plate 215 is adapted to the shape of the guide groove 216. When the position of the limiting baffle 202 is adjusted, the guide slide plate 215 slides in a direction within the guide groove 216, thereby allowing the limiting baffle 202 to move in a direction within the wheel groove 106.
[0048] Based on the above embodiments, it can be concluded that when sowing seeds, according to the size of the seeds and the planting density, rotating the rotating bolt 214 drives the power bevel gear 213 to rotate. Utilizing the meshing between the driving bevel gear 212 and the power bevel gear 213, the threaded pressure plate 210 slides outside the threaded rod 209. During the movement of the threaded pressure plate 210, the adjusting frame 206 moves, and under the action of the pulling arc plate 204, the pressing push plate 203 deforms, pushing the limiting baffles 202 outward, thereby adjusting the distance between the limiting baffles 202, and thus adjusting the capacity of the wheel groove 106. This allows for adjustment of the seed sowing amount to ensure a suitable planting density. Simultaneously, during the adjustment of the wheel groove 106, its size can be adjusted to sow seeds of different shapes and sizes, ensuring the applicability of the device.
