Description

TECHNICAL FIELD

[0001] The utility model belongs to rice planting technical field, concretely relates to a novel seedling strip assembly for dry sowing rice planting. BACKGROUND

[0002] Rice direct seeding is a rice planting method that rice seeds are directly sown in the field, without the procedures of seedling raising, seedling pulling and transplanting. Among them, dry direct seeding of rice is the simplest planting method in light cultivation of rice. Dry direct seeding is to plow and sow in the dry field, and the rice seeds are sown in the shallow soil layer of 1cm-2cm. After the rice seedlings emerge, the rice enters the 4-leaf stage and starts tillering. The spacing, depth and other parameters of the sowing ditch opened by dry direct seeding have a significant impact on the tillering and growth of rice.

[0003] For example, a rice dry direct seeding machine pressure ditch assembly is disclosed in Chinese patent (publication number: CN218302171U), which relates to the technical field of rice dry direct seeding. The assembly includes a connecting shaft, a main shaft connected to the connecting shaft, and a plurality of pressure ditch groups connected to the main shaft. The spacing between adjacent pressure ditch groups is 25cm-50cm. The assembly can provide a reasonable ridge spacing to obtain higher rice yield. However, the main shaft is too long in actual use. One end of the main shaft is driven by a transmission structure composed of a connecting rod. However, the length of the main shaft is generally 3 meters. The long main shaft may vibrate during rotation, which can damage the bearings connected to the two ends of the main shaft. In addition, the width of the seedling strip pressed by the rotating pressure ditch group is wide, and the rice seeds transported by the seed tube into the seedling strip may be aggregated. When there are orange poles and hard soil blocks on the ground, the orange poles and hard soil blocks may press on the surface of the seedling strip, and the rice seeds moving into the seedling strip may fall onto the surface of the orange poles and hard soil blocks, which may cause the roots of the rice seeds to fail to penetrate into the soil, thereby affecting the growth of the roots of the rice seeds. Therefore, a novel seedling strip assembly for dry sowing rice planting is needed to solve the above problems. SUMMARY

[0004] The utility model aims at providing a novel seedling strip assembly for dry sowing rice planting to solve the problems in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a novel seedling strip assembly for dry sowing rice planting, which comprises a main shaft, a seedling strip pressing assembly and a transmission assembly.

The seedling strip pressing assembly comprises two seedling pressing discs and a sawtooth-shaped isolation disc. The two seedling pressing discs and the sawtooth-shaped isolation disc are clamped outside the main shaft. The sawtooth-shaped isolation disc is connected between the corresponding two seedling pressing discs. The transmission assembly is arranged at the middle part of the main shaft.

[0006] Through the above structure, the seedling strip assembly can improve the seedling rate and effective survival rate of rice seeds, improve the growth conditions of each seedling, increase the main ear yield, promote effective tillering, and ultimately obtain high yield.

[0007] As a preferred scheme, the transmission assembly comprises a worm, a worm wheel and a protection box, the worm is engaged with the worm wheel, the worm wheel is clamped outside the main shaft, and the worm and the main shaft are rotationally connected in the protection box.

[0008] As a preferred scheme, the worm wheel is located at the middle part of the main shaft and is arranged in the protection box.

[0009] As a preferred scheme, three seedling pressing assemblies are arranged as a group, the gap between two adjacent seedling pressing assemblies in each group is 24 cm, and the gap between two adjacent groups of seedling pressing assemblies is 28 cm.

[0010] As a preferred scheme, the width of the seedling pressing disc is 3.5 cm, the width of the sawtooth-shaped isolation disc is 0.9 cm, and the radius of the seedling pressing disc is greater than the radius of the main shaft and is 4 cm.

[0011] As a preferred scheme, the diameter of the sawtooth-shaped isolation disc is greater than the diameter of the seedling pressing disc and is 5 cm.
