Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, and in particular to a multi-adaptive no-till precision seeder with adjustable row spacing. Background Technology

[0002] A seeder is an agricultural machine mainly used to sow seeds into the soil at a certain row spacing, plant spacing, and depth to achieve crop sowing. When the seeder is working, the furrow opener first opens seed furrows on the soil surface. Then, the seed metering device evenly discharges the seeds from the seed box according to the set sowing rate and frequency, and transports the seeds to the seed furrows opened by the furrow opener through the seed delivery pipe. Next, the soil covering device covers the seeds with soil to complete the sowing process. Finally, the compaction wheel compacts the soil after sowing to ensure that the seeds are in close contact with the soil. Throughout the sowing process, all parts of the seeder work together to ensure that the seeds are accurately sown into the soil at a certain row spacing, plant spacing, and depth, providing a good foundation for crop growth.

[0003] Most no-till precision seeders on the market have their row spacing set at the factory, making it difficult for users to change the row spacing according to their own agronomic requirements. In addition, they can only sow a single crop and cannot sow multiple crops. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-adaptive no-till precision seeder with adjustable row spacing, aiming to improve the problem that the existing technology can only sow a single crop and cannot sow multiple crops.

Specific Embodiment

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] Refer to Figure 2 , Figure 5 and Figure 6 , an embodiment provided by the present utility model: a no-till precision seeder with adjustable row spacing and multiple adaptabilities, including a frame component 1. A seeding component 5 is installed at the rear side of the top of the frame component 1. A transmission component 4 is installed at the rear side of the frame component 1. A plurality of fertilizing components 3 are installed equidistantly at the bottom of the frame component 1. A fertilizer discharging component 2 is installed at the front side of the top of the frame component 1. A main beam with a cross-section of the Chinese character "Mi" 6 is installed inside the frame component 1; an outer shell of the seed metering device 19 is installed outside the frame component 1, and a seed metering disc 18 is rotatably connected inside the outer shell of the seed metering device 19;

[0026] Specifically, the main beam is a special-shaped steel pipe beam with a cross-section of the Chinese character "Mi". It can freely arrange the positions of the components fastened by hook bolts 12 on it to achieve variable row spacing. The fertilizing component 3 and the seeding component 5 are both connected to the main beam of the frame through hook bolts 12. Therefore, by releasing the hook bolts 12 on the fertilizing component 3 and the seeding component 5, the adjustment of the row spacing can be easily achieved. Open the end cover of the seed metering device 16 and pull out the locking pin, and the seed metering disc 18 can be replaced. Different seed metering discs 18 can be used to sow different crops. In this way, users can prepare different seed metering discs 18 for operation according to their planting needs, so as to achieve the purpose of planting different crops according to different agronomic requirements with one seeder, reducing the planting cost and relatively increasing the income.

[0027] Refer to Figure 1 , Figure 3 and Figure 4 Seed boxes 17 are installed on the top left and right sides of the frame component 1. Seed metering device 16 is fixedly connected to the middle of the outer side of the frame component 1. Hook bolts 12 are installed on the front side of the outer wall of the frame component 1. Hook bolts 12 are connected to the parallel four-bar linkage 11. Stubble clearing device 13 is installed on the front side of the bottom of the frame component 1. Depth limiting wheels 14 are installed on the left and right sides of the bottom of the frame component 1. Presser 15 is installed at the rear end of the bottom of the frame component 1.

[0028] Specifically, during operation, the power provided by the transmission component 4 drives the seed metering device 16 to rotate via sprockets and chains, completing the sowing operation. By loosening the hook bolt 12, the sowing component 5 can be moved horizontally, achieving adjustable row spacing.

[0029] Reference Figure 7 A gearbox 10 is mounted on the outside of the hook bolt 12. A drive shaft 9 is rotatably connected to the bottom of the gearbox 10. A chain box 8 is mounted on the outer wall of the hook bolt 12. A ground wheel 7 is mounted on the outside of the chain box 8.

[0030] Specifically, the ground wheel 7 rotates due to the tractor's traction and friction with the ground, generating driving force, which drives the chain drive gearbox 10 to change speed and then drives the drive shaft 9 to provide power to the sowing component 5.

[0031] Working principle: When the tractor is carrying the no-till precision seeder, the ground wheel 7 of the transmission component 4 generates power, which drives the seed metering device 16 through the drive shaft 9 to perform the sowing operation. When the row spacing needs to be changed due to agronomic requirements in different regions, the hook bolts 12 of the fertilizer component 3 and the sowing component 5 can be loosened, the relevant components can be moved along the main beam to achieve the required row spacing, and then the hook bolts 12 can be tightened to complete the row spacing adjustment. When different crops need to be sown, the seed metering disc 18 in the seed metering device 16 can be replaced, the end cover of the seed metering device 16 can be closed, and the drive can be connected to perform crop switching and sowing.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
