Description

Technical Field

[0001] This invention relates to the field of agricultural technology, and in particular to an integrated dryland seeding machine. Background Technology

[0002] Dryland farming is the main agricultural production method in arid and semi-arid regions of my country. Its core challenges lie in water scarcity and poor soil conditions. Sowing, as a crucial link in agricultural production, directly affects crop emergence rate, growth status, and final yield. Under dryland farming conditions, the soil generally suffers from problems such as high hardness, easy compaction, and poor water retention. This places special demands on the performance of sowing equipment: it not only needs to accurately sow seeds to the appropriate depth, but also often requires local loosening and compaction of the seedbed before and after sowing to create a microenvironment conducive to seed germination and seedling growth.

[0003] Currently, seeders used in dryland farming areas have the following main shortcomings:

[0004] First, they are highly dependent on power sources and have low energy efficiency. Most precision seeders on the market rely on the tractor's power take-off shaft or additional electric motors and hydraulic motors for their core seeding and drive systems. This design not only increases manufacturing costs and structural complexity but also consumes extra energy in the transmission process, resulting in low overall energy efficiency. This makes them particularly unsuitable for small and medium-sized farmers or operations with limited power.

[0005] Secondly, sowing quality and soil adaptability need improvement. Traditional mechanical seed metering devices easily cause mechanical damage to seeds and have strict requirements on seed size and shape; the uniformity of sowing rate is greatly affected by the operating speed. While pneumatic seeders can reduce seed damage and improve accuracy, they generally require independent high-speed fans, resulting in significant power consumption. More importantly, existing seeders are mostly focused on the "sowing" itself. In compacted soils common in drylands, seeds often fail to absorb water and germinate properly after sowing due to poor seed-soil contact, and the consistency of sowing depth is also difficult to guarantee.

[0006] Furthermore, the separation of processes leads to low operational efficiency. Ideal dryland sowing typically involves multiple steps, such as "stubble breaking / loosening, furrowing, sowing, covering, and compaction." Currently, in practice, multiple machines are often required operating sequentially, or complex and cumbersome combined operation machines are used. The former results in multiple field visits, soil compaction, and increased energy consumption and labor time; the latter leads to bulky machines, high costs, and inconvenient adjustments. In particular, the function of localized fine loosening and backfilling at the sowing point is poorly integrated in existing equipment, often requiring separate subsequent cultivation operations, making it impossible to achieve a single-operation coordinated operation of sowing and seedbed preparation.

[0007] Finally, the equipment lacks integration and versatility. Many seeders have limited functionality and are difficult to adjust the loosening intensity, sowing depth, and soil covering amount according to different dryland conditions. Loosely structured and complex attachments also hinder the quick installation and switching between different models of tractors and other agricultural mobile equipment, reducing equipment utilization and operational flexibility.

[0008] The present invention aims to solve the technical problems existing in the prior art, and to this end, proposes an integrated dryland seeding machine. Summary of the Invention

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. High efficiency and energy saving, self-sufficient in power.

[0029] The core drive of the seeder cleverly utilizes the periodic lifting and lowering motion that inevitably occurs when the seeder operates with agricultural equipment as its power source.

[0030] Without the need for additional motors, engines, or other independent power units, the mechanical energy of lifting is converted into airflow power and mechanical oscillation through a mechanical structure, achieving self-circulation of energy and significantly reducing equipment complexity and energy consumption.

[0031] 2. Pneumatic seeding, precise and reliable.

[0032] It adopts a unique reciprocating pneumatic flow guiding system. When the annular telescopic airbag is compressed, gas is blown into the storage cylinder to stir the seeds / fertilizer and prevent clumping; when it is inhaled and reset, a negative pressure is formed, which draws in a certain amount of material and propels it to the sowing end in stages.

[0033] The annular segmented airbag and continuous material guiding chamber design in the multi-stage material guiding and seeding module ensures that the material is transported in segments, in a quantitative manner, and in an orderly manner, effectively preventing pipeline blockage and uneven seeding.

[0034] The combination of the spray nozzle and the soil retaining ring ensures that the seeds are sprayed into the soil at the appropriate time and with a certain pressure to a specified depth, thus improving the accuracy, uniformity and germination rate of sowing.

[0035] 3. Simultaneous soil loosening saves labor and improves quality.

[0036] A synchronous dryland soil loosening mechanism was designed, which is fully mechanically linked to the sowing action. The loosening cone is inserted into the soil at the same time as the sowing column enters the soil, and moves down and rotates accordingly. Through the screw drive plate and loosening teeth, it effectively breaks up and pries the compacted soil around the sowing point.

[0037] The swing amplitude of the loosening component can be controlled by the synchronous adjustment module, so that when the seeding column is raised, some of the loosened soil is backfilled and gathered to the seeding point.

[0038] This design enables the simultaneous completion of sowing and localized fine soil loosening in one step, which not only improves the seedbed environment, promoting seed germination and root growth, but also reduces soil moisture evaporation, creating conditions for rapid water and fertilizer penetration, thus achieving the effects of saving water and fertilizer and reducing the labor required for subsequent separate soil loosening operations.

[0039] 4. Structural integration and strong adaptability

[0040] The equipment integrates multiple functional modules such as material storage, flow guidance, quantitative seeding, and synchronous soil loosening into a compact support and mounting cylinder and surrounding structure, resulting in a compact structure and strong overall integrity.

[0041] The ring-shaped mounting plate makes it easy to install on various agricultural mobile devices, offering good versatility.

[0042] Specifically designed for the soil characteristics of dryland fields, such as high hardness and easy compaction, the structure of soil breaking cone, mud guiding trough, and loosening teeth can effectively cope with the dryland operation environment, improving the reliability and applicability of agricultural operations in arid and semi-arid regions.

Detailed Implementation

[0054] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0055] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0056] Example 1, please refer to Figures 1-2In this embodiment of the invention, an integrated dryland seeder includes a support mounting cylinder 7, an annular mounting plate 1 positioned directly above the support mounting cylinder 7, and a plurality of support mounting brackets 6 arranged at equal angles on one side of the annular mounting plate 1. The outer ends of the support mounting brackets 6 are fixed to the support mounting cylinder 7. The annular mounting plate 1 has a plurality of fixing mounting holes 2. The device also includes:

[0057] The upper end of the support mounting cylinder 7 is provided with a transfer storage cylinder 5, the upper end of the transfer storage cylinder 5 is provided with a telescopic feed pipe 3, the outer end of the telescopic feed pipe 3 is provided with a connecting flange 4, the inner side of the connecting flange 4 is provided with a sealing rubber ring 31, and one end of the telescopic feed pipe 3 is provided with a sealing gate 49.

[0058] The pneumatic material guiding and seeding mechanism includes a reciprocating pneumatic flow guiding module and a multi-stage material guiding and seeding module;

[0059] The synchronous dryland soil loosening mechanism includes a synchronous adjustment module and several synchronous soil loosening modules set at equal angles on the outer side of the support mounting cylinder 7.

[0060] By connecting the connecting flange 4 to the external feeding equipment, the external fertilizer can be smoothly guided through the telescopic feed pipe 3. At the same time, the seeder is fixed to the external agricultural mobile equipment through the annular mounting plate 1 and its fixed mounting holes 2, so that the seeder can perform periodic lifting and lowering operations as the mobile equipment moves. The agricultural mobile equipment can be a tractor or other agricultural engineering machinery.

[0061] With the movement and periodic lifting drive of the external agricultural mobile equipment, the seeder performs seeding operations periodically. Specifically, through the periodic lifting drive, the reciprocating pneumatic guide module operates. When the multi-stage seeding module is inserted into the dryland field, the seeds are carried into the soil by the airflow to complete the seeding operation.

[0062] Meanwhile, the synchronous soil loosening module is driven by the cycle of lifting and lowering. As the sowing progresses, it repeatedly inserts into the ground and pulls out of the ground. Together with the synchronous adjustment module, it loosens the soil around the sowing point and gathers the loosened soil towards the sowing point to ensure the quality of sowing. This also makes it easier for subsequent watering and fertilization to quickly penetrate into the sowing point, reducing the amount of water and fertilizer used.

[0063] The periodic lifting drive can be hydraulically driven or a linkage drive.

[0064] Example 2, based on Example 1, please refer to... Figures 1 to 7In this embodiment of the invention, the reciprocating pneumatic guide module is mounted on the support mounting cylinder 7, including a guide mounting hole 23 at the lower end of the support mounting cylinder 7, a guide mounting post 50 is provided in conjunction with the guide mounting hole 23, one end of the guide mounting post 50 is in conjunction with a transmission mounting plate 19 inside the support mounting cylinder 7, an annular telescopic airbag 20 is connected between the transmission mounting plate 19 and the top of the support mounting cylinder 7, a plurality of return springs 21 are provided at equal angles on the transmission mounting plate 19 outside the annular telescopic airbag 20, the upper ends of the return springs 21 are all fixed on the top of the support mounting cylinder 7, a plurality of directional guide posts 35 are provided at equal angles on the outer side of the guide mounting post 50, and directional guide grooves 34 are provided on the inner side of the guide mounting hole 23 in conjunction with the directional guide posts 35;

[0065] A material guide hole 22 is provided at the middle of the lower end of the transfer storage cylinder 5. The material guide hole 22 is connected to the space enclosed by the annular telescopic air bag 20. An annular flow guide cavity 38 is provided at the connection between the transfer storage cylinder 5 and the support mounting cylinder 7. Several air blowing holes 32 are provided at equal angles at the upper end of the annular flow guide cavity 38. All air blowing holes 32 are connected to the interior of the transfer storage cylinder 5. Several air outlet guide holes 37 are provided at equal angles at the lower end of the annular flow guide cavity 38. All air outlet guide holes 37 are connected to the annular telescopic air bag 20. An air outlet one-way valve 36 is provided in conjunction with each air outlet guide hole 37.

[0066] The upper end of the support mounting cylinder 7 on the outer side of the transfer storage cylinder 5 is provided with several air suction guide holes 41. All air suction guide holes 41 are connected to the annular telescopic airbag 20. Each air suction guide hole 41 is provided with an air suction one-way valve 33. The upper end of the support mounting cylinder 7 is provided with a filter screen cover 18 in conjunction with the air suction one-way valve 33.

[0067] The multi-stage material guiding and sowing module includes a sowing installation column 11 at the lower end of the guide installation column 50, a soil breaking cone 13 at the end of the sowing installation column 11, and a plurality of mud guiding grooves 16 at equal angles on the outer side of the soil breaking cone 13. A continuous material guiding cavity 28 is provided in the middle position of the sowing installation column 11, the guide installation column 50 and the transmission installation plate 19. The upper end of the continuous material guiding cavity 28 is connected to the space enclosed by the annular telescopic airbag 20. A plurality of annular segmented airbags 29 are provided at equal intervals inside the continuous material guiding cavity 28.

[0068] The continuous material guiding cavity 28 is provided with a spraying cavity 30 at its end. A plurality of spraying holes 12 are provided at equal angles on the spraying cavity 30. All spraying holes 12 extend out of the sowing installation column 11, and soil retaining rings 27 are provided on the outer sides of the sowing installation column 11 on both the upper and lower sides of the spraying hole 12.

[0069] Two opposing gates 39 are symmetrically arranged on one side of the feed guide hole 22. The opposing gates 39 are connected to the support mounting cylinder 7 through the reset shaft 40.

[0070] As the seeder rises and falls cyclically, when the soil-breaking cone 13 comes into contact with the dryland field, it creates resistance, causing the seeding mounting column 11, guide mounting column 50, and transmission mounting disc 19 to move within the support mounting cylinder 7. Under the directional sliding cooperation of the directional guide column 35 and directional guide groove 34, the transmission mounting disc 19 squeezes the annular telescopic airbag 20, causing the gas in the annular telescopic airbag 20 to be introduced into the annular guide cavity 38 through the outlet one-way valve 36 from the outlet guide hole 37, and then discharged from the blowing hole 32 in the annular guide cavity 38, stirring the seeds in the transfer storage cylinder 5. When fertilization is required at the same time as sowing, it can make the seeds and fertilizers mix evenly.

[0071] Since the sealing gate 49 is only opened when the transfer storage cylinder 5 is being fed, when the annular telescopic airbag 20 reaches its compression limit, the pressure inside the transfer storage cylinder 5 is sufficient to open the split gate 39, allowing the material inside the transfer storage cylinder 5 to be guided into the space enclosed by the annular telescopic airbag 20. Subsequently, the split gate 39 is closed under the action of the reset shaft 40, and the material then enters the continuous guide chamber 28. As the seeder is lifted, the reset spring 21 pushes the transmission mounting plate 19 to reset. At this time, air is introduced into the annular telescopic airbag 20 through the filter screen 18 and the suction one-way valve 33 from the suction guide hole 41, causing the annular telescopic airbag 20 to suck in air and return to its original state.

[0072] Repeat the above steps so that the seeds or seed-fertilizer mixture pass through the annular segmented airbag 29 one by one until the seeds or seed-fertilizer mixture is introduced into the spray chamber 30 and discharged from the spray hole 12. In each subsequent cycle of lifting and lowering operation, a certain amount of seeds or seed-fertilizer mixture is discharged from the spray hole 12 just when the annular telescopic airbag 20 reaches the compression limit. At this time, the sowing installation column 11 is inserted into the soil to a certain depth, completing the continuous sowing operation.

[0073] The retaining ring 27 can reduce the amount of soil entering the spray hole 12 when the soil-breaking cone 13 is inserted into the ground, ensuring continuous and stable sowing.

[0074] Example 3, based on Example 2, please refer to... Figures 1-4 , Figure 8 , Figure 9 In this embodiment of the invention, the synchronous soil loosening module includes a connecting mounting frame 42 provided on the outside of the supporting mounting cylinder 7. A connecting rotating column 43 is rotatably provided on the connecting mounting frame 42. A swing mounting rod 8 is provided on the connecting rotating column 43. A limiting rotating sleeve 45 is provided at the outer end of the swing mounting rod 8. A soil loosening rotating column 9 is provided directly opposite the limiting rotating sleeve 45. A limiting rotating column 44 is provided at one end of the soil loosening rotating column 9 in conjunction with the limiting rotating sleeve 45. A soil loosening cone 47 is provided at the other end of the soil loosening rotating column 9.

[0075] The outer side of the loosening cone 47 and the loosening rotating column 9 is provided with a spiral transmission plate 46, and the outer side of the spiral transmission plate 46 is provided with a number of loosening teeth 10, the length of the loosening teeth 10 increasing from bottom to top.

[0076] The synchronous adjustment module includes an annular guide groove 15 on the outside of the seeding installation column 11. A drive installation ring 24 is provided at one end of the annular guide groove 15. A guide displacement cylinder 17 is slidably arranged on the annular guide groove 15. A synchronous top ring 14 is provided on the outside of the guide displacement cylinder 17 through a transmission rod 26 arranged at equal angles. A curved top block 48 is provided on one side of the swing installation rod 8 in conjunction with the synchronous top ring 14. The drive installation ring 24 and the guide displacement cylinder 17 are connected by a number of synchronous drive telescopic columns 25.

[0077] As the seeder moves up and down cyclically, when the soil-breaking cone 13 is inserted into the soil, the soil-loosening cone 47 on the soil-loosening rotating column 9 is also inserted into the soil. As the seeder moves down, part of the soil-loosening rotating column 9 is submerged in the soil. At this time, due to the presence of the screw drive plate 46, the soil-loosening rotating column 9 rotates during the process of being inserted into the soil, with the cooperation of the limiting rotating column 44 and the limiting rotating sleeve 45. When it is inserted to a certain depth, the synchronous top ring 14 slides over the curved top block 48, causing the swing mounting rod 8 to rotate around the connecting rotating column 43 on the connecting mounting frame 42. The soil is pried up by the soil-loosening rotating column 9, the screw drive plate 46 and the soil-loosening teeth 10, improving the quality of soil loosening.

[0078] As the seeder is lifted, the spiral drive plate 46 inserted into the soil and its loosening teeth 10 move upward. At the same time, the loosening rotating column 9 rotates in the opposite direction at a certain angle and, together with the loosening teeth 10, brings up some soil. The transmission mounting plate 19 resets, and the synchronous top ring 14 slides in the opposite direction over the curved top block 48, causing the swing mounting rod 8 to rotate again, so that the soil brought up falls towards the sowing point as the swing mounting rod 8 rotates.

[0079] The synchronous drive telescopic column 25 causes the guide displacement cylinder 17 to slide and shift on the annular guide groove 15, changing the position of the synchronous top ring 14, thereby adjusting the swing amplitude of the swing mounting rod 8.
