Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and more particularly to the field of precision seeders. Background Art

[0002] Traditional seed cleaning and seed guiding are divided into two independent parts and need to be carried out separately during operation, resulting in high energy consumption and low operation efficiency. This not only increases the complexity of the equipment but also increases the maintenance and use costs. This seed cleaning and guiding device combines seed cleaning and seed guiding, which can reduce the complexity of the equipment and the maintenance and use costs. Summary of the Invention

[0003] A seed cleaning and guiding device provided by the utility model can combine a seed cleaning device and a seed guiding device and place them at a position corresponding to the seed metering device, and use positive pressure air flow for seed cleaning and guiding, which can solve the above problems.

[0004] The utility model provides a seed cleaning and guiding device, which includes a seed metering disc, a furrow opening disc, an air pipe, a frame, a seed taking box, a special-shaped shaft, etc. The seed metering disc and the furrow opening disc are connected to the special-shaped shaft, and the air pipe and the seed taking box are installed on the frame. The air pipe integrates the functions of seed cleaning and seed guiding, is located above the left of the seed metering disc and corresponds to it. During operation, positive pressure gas is shunted above the air pipe: the short pipe on the right clears the redundant seeds on the seed metering disc and guides them into the seed taking box; the long pipe on the left blows downward to form a negative pressure area to assist the seeds in the seed suction holes to fall off for sowing. This device can reduce the reseeding rate and hole rate, reduce seed damage, and improve the sowing efficiency and the crop growth qualification rate.

[0005] Furthermore, the seed cleaning air pipe opening on the right side of the air pipe is aligned with the circumferential side of the seed metering disc and faces into the seed taking box; the seed guiding air pipe opening on the left side of the air pipe is aligned with the circumferential part on the left side of the seed metering disc and faces downward; the upper side pipe of the air pipe is externally connected to positive pressure gas, and the whole pipe type is vertically fixed on the frame.

[0006] By adopting the above solutions, the beneficial effects of the utility model are as follows: The air-blowing assisted seed cleaning and guiding device designed by the utility model has a compact, simple and reasonable structure, which can reduce the complexity of the equipment, the maintenance and use costs, reduce the reseeding rate and hole rate of seeds, and reduce the damage to seeds.

[0012] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] The utility model provides a seed cleaning and guiding device, and the air-blowing assisted seed cleaning and guiding device comprises a seeding disc 1, a furrowing disc 3, an air pipe 4, a frame 5, a seed taking box 6, a special-shaped shaft 7, etc. The furrowing disc 3 of the seeding disc 1 is connected to the special-shaped shaft 7, the air pipe 4 and the seed taking box 6 are connected to the frame, and the air pipe 4 combines seed cleaning and seed guiding, is located at the upper left of the seeding disc 1 and corresponds to the position of the seeding disc.

[0014] During operation, the pipeline above the air pipe 4 is connected to positive pressure gas, and the gas is diverted in the air pipe 4. The gas diverted to the short tube on the right side of the air pipe is used to remove excess seeds on the seeding disk 1 and guide them into the seed box 6. The gas diverted to the long tube on the left side of the air pipe 4 is blown downward along the circumference of the seeding disk 1 to form a negative pressure area, which assists the seeds 8 in the seed suction hole 2 to fall off and complete the sowing. The seed cleaning and guiding device provided by the utility model has a compact, simple and reasonable structure, which can reduce the reseeding rate and the hole rate of seeds, reduce the damage to seeds, and improve the qualified growth rate of seeds.

[0015] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
