Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural planting machinery, in particular to an intelligent seeding device for deep loosening and layered fertilization. BACKGROUND

[0002] When agricultural seeding is performed, in order to provide sufficient nutrients for crop production, fertilization operation needs to be performed at the same time as seeding. In the prior art, when seeding is performed, a furrow is generally opened in the farmland by a furrowing shovel, and then fertilization and seeding are performed in the furrow. In order to avoid the phenomenon of seedling burning caused by direct contact between seeds and fertilizer, fertilization and seeding are generally performed separately, that is, fertilization is first performed in the furrow, and after fertilization is completed, a layer of soil is covered, and then seeding is performed, and after seeding is completed, secondary soil covering is performed. This planting method needs to perform multiple processes such as furrowing, fertilization, primary soil covering, seeding, and secondary soil covering, thereby resulting in low seeding efficiency. The existing seeding device needs to move the device back after furrowing, fertilization, and primary soil covering to achieve seeding and secondary soil covering when seeding is performed, especially when layered fertilization and seeding are performed, which results in a complicated layered soil covering and fertilization process, and fertilization, primary soil covering, seeding, and secondary soil covering need to be driven by multiple driving devices, and cannot be controlled by a single driving device at the same time as the device is moved. Therefore, the present application provides an intelligent seeding device for deep loosening and layered fertilization. SUMMARY

[0003] The present application aims to provide an intelligent seeding device for deep loosening and layered fertilization, which simplifies the operation process of seeding and fertilization, reduces repeated steps such as furrowing, fertilization, soil covering, and seeding, and improves seeding efficiency. The present application also aims to provide an intelligent seeding device for deep loosening and layered fertilization, which can complete layered fertilization and seeding without reciprocating the device, and simultaneously controls the actions of fertilization, primary soil covering, seeding, and secondary soil covering by a single driving device, thereby reducing the complexity of the device structure and use cost.

[0013] Beneficial effects: In response to the problem that existing technologies require multiple decentralized processes for sowing, such as trenching, fertilization, primary covering, sowing, and secondary covering, and often require reciprocating moving devices to complete layered fertilization and sowing, this device achieves continuous operation of "fertilization - primary covering - sowing - secondary covering" through the coordinated linkage of various mechanisms. During the movement of the device, there is no need to turn back and forth. All key processes can be completed in the reasonable order required for agricultural production. This completely reduces the repetitive steps in the process, effectively shortens the time of a single sowing operation, and significantly improves the overall sowing efficiency. It is especially suitable for large-scale sowing operations in large areas of farmland. The existing layered fertilization seeding device often needs multiple driving devices to control fertilization, soil covering, seeding and other actions, resulting in complex device structure and high failure rate. The device relies on unique mechanism design and can control the entire operation process synchronously through a single driving mechanism: the driving mechanism first acts on the corresponding hydraulic mechanism of fertilization to trigger the discharging mechanism to complete fertilization; when the hydraulic mechanism resets, the soil covering mechanism is driven through the linkage mechanism to realize one-time soil covering; then the driving mechanism continues to operate and acts on the hydraulic mechanism corresponding to seeding to control the discharging mechanism to complete seeding, and finally the soil covering mechanism is driven through the hydraulic mechanism reset to realize two-time soil covering. The entire process does not need to additionally add multiple driving components, greatly simplifies the overall structure of the device, reduces the probability of mechanical failure, and is also convenient for later maintenance and repair. To solve the problem that direct contact between seeds and fertilizers easily leads to seedling burn, the device realizes layered isolation of fertilizers and seeds through precise process design and mechanism cooperation. The left soil covering mechanism corresponds to the trench after fertilization, pushes the soil above the fertilizer to complete one-time soil covering and form an isolation layer; the right soil covering mechanism corresponds to the trench after seeding, covers the seeds again to make the fertilizer in the lower layer and the seed in the upper layer, and there is soil separation between the two layers, which fundamentally avoids direct contact between seeds and fertilizers, guarantees normal germination and growth of seeds, and improves the emergence rate after seeding and the growth quality of crops in the early stage. On the one hand, compared with multiple driving devices, the single driving device design greatly reduces the procurement and manufacturing cost of core components and reduces the overall production cost of the device; on the other hand, the simplified structure makes the device consume less energy during daily use, reduces the number of vulnerable components, and reduces the frequency and cost of later maintenance and replacement of components. In addition, the operation logic of each mechanism of the device is clear, the dozer plate of the soil covering mechanism in the non-working state can keep open, which facilitates the movement and alignment of the device, reduces the difficulty of use for the operator, and further improves the practicality and economy of the device in actual agricultural production.
