Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology, and more specifically, to a Beidou-navigated unmanned seeding, fertilizing, and mulching integrated machine. Background Technology

[0002] Sowing, fertilizing, and mulching are the core basic processes in modern agricultural planting and production. Mechanized integrated operation equipment can effectively improve field planting efficiency. With the rapid development of smart agriculture and precision agriculture technologies, Beidou unmanned driving, precision variable fertilization, and synchronous mulching integrated operation have become the mainstream development direction of modern agricultural planting machinery, which puts forward higher requirements for the degree of automation, seed and fertilizer matching accuracy, fertilizer uniformity, and operation integration of planting equipment.

[0003] Traditional integrated seeding and fertilization equipment still has many inherent technical defects in actual field operations. The most prominent problems are unreasonable seed and fertilizer layout and poor fertilizer uniformity. Most existing planting and fertilization equipment adopts an operation mode of alternating seeds and fertilizers on one side. The fertilizer is concentrated in the soil area on one side of the seed, and the soil fertility distribution around the seed is extremely uneven, showing a clear distribution characteristic of one-sided enrichment and surrounding infertility. This operation mode will directly cause the crop roots to grow towards the fertilizer-rich side, resulting in skewed root development, uneven root distribution, and large differences in plant growth. This not only seriously affects the crop's lodging resistance and balanced nutrient absorption in the later stage, but also easily leads to local fertilizer burn and local nutrient deficiency and weak seedlings, significantly reducing crop yield and quality.

[0004] Traditional integrated seeding and fertilizing machines have low levels of mechanization and intelligence, mostly relying on manual operation and manual calibration of the work trajectory. Manual operation results in large errors and frequent deviations from the work trajectory, making it impossible to achieve high-precision unmanned autonomous operation. They are also weak in adapting to large-scale and standardized field planting. The feeding and distributing structures of traditional equipment are simple and crude, mostly using fixed quantitative discharging structures, which result in poor discharging uniformity and problems such as material blockage, interruption, and leakage. It is also difficult to accurately control the sowing spacing and fertilizer application rate, and the synchronization of seed and fertilizer application is poor, further exacerbating the problem of insufficient uniformity in field planting.

[0005] Existing integrated machines have low integration levels, and most can only achieve single sowing and fertilization functions. They are difficult to simultaneously complete integrated continuous operations such as land preparation, ditching, sowing, circular uniform fertilization, and mulching and compaction. The process is cumbersome and the work efficiency is low. Traditional fertilization structures are mostly fixed single-point direct fertilization methods, with small fertilization coverage, concentrated fertilizer accumulation, slow soil nutrient diffusion, and low fertilizer utilization. They cannot achieve circular uniform fertilization around the seeds and cannot solve the industry pain points of uneven root growth and uneven growth from a structural perspective.

[0006] Existing sowing, fertilizing, and mulching equipment suffers from numerous technical defects, including low intelligence, reliance on manual operation, uneven distribution of seeds and fertilizers, severe root eccentricity, small fertilization coverage, poor operational integration, and insufficient operational stability. These defects make it difficult to meet the high-precision, unmanned, uniform, and integrated planting needs of modern smart agriculture. Therefore, it is necessary to design a Beidou navigation-guided unmanned sowing, fertilizing, and mulching integrated machine to solve the problems existing in the current technology. Summary of the Invention

[0007] The purpose of this invention is to provide a Beidou navigation-guided unmanned seeding, fertilizing, and mulching integrated machine to solve the problems mentioned in the background art.

[0008] A Beidou navigation-guided unmanned seeding, fertilizing, and mulching integrated machine includes a material collection cylinder, a main frame fixedly installed on the lower side of the material collection cylinder, and a protective frame fixedly installed on the side of the main frame.

The lower end of the material distribution box is provided with several discharge parts at equal intervals. The lower end of each discharge part is fixedly installed with a discharge outer sleeve. A fertilizer pipe is slidably arranged in the middle of the discharge outer sleeve. A control box is fixedly installed on the side of the discharge part.

A fertilizer pipe is fixedly installed in the middle of the inner cavity of the discharge outer sleeve. A second drive motor is fixedly installed inside the control box. A half gear is fixedly installed at the output end of the second drive motor. A sliding frame is fixedly installed in the middle of the inner cavity of the control box. A reciprocating toothed frame is slidably arranged in the middle of the sliding frame. The side of the reciprocating toothed frame is fixed to the fertilizer pipe. A spreading pipe is fixedly installed on the outer side of the lower end of the discharge outer sleeve.

[0009] Furthermore, a navigation vehicle body is provided on the side of the main frame, and the navigation vehicle body is fixedly connected to the main frame via a metal connecting rod.

[0010] By adopting the above technical solution, the navigation vehicle body can drive the entire device to move. The navigation vehicle body is equipped with Beidou navigation and control devices, which can automatically carry out planting and fertilization.

[0011] Furthermore, an isolation plate is fixedly installed in the middle of the storage cylinder, a protective plate is rotatably installed at the upper end of the storage cylinder, and cleaning pipes are fixedly installed on both sides of the storage cylinder.

[0012] By adopting the above technical solution, the partition plate divides the inner cavity of the material storage cylinder into two halves, and the protective plate can rotate to seal and cover the upper end of the material storage cylinder.

[0013] Furthermore, the first drive motor is electrically connected to the navigation vehicle body, and a baffle plate is fixedly installed on the middle side of the main frame.

[0014] By adopting the above technical solution, the motor inside the first drive motor can be started and stopped by the navigation vehicle body, thereby controlling the discharge of seeds and fertilizer.

[0015] Furthermore, both the lower ends of the first and second feeding boxes are provided with connecting pipes. The lower end of the first feeding box is fixedly connected to the dispensing box through the connecting pipes, and the side of the first feeding box is connected to the first drive motor.

[0016] By adopting the above technical solution, the first and second feeding boxes can discharge the fertilizer and seeds inside into the distribution box through the connecting pipe, thereby achieving regular material discharge.

[0017] Furthermore, the material distribution box is equipped with a partition plate inside, a plowing rod is fixedly installed on the lower side of the main frame, a number of soil turning parts are equidistantly arranged on the lower side of the plowing rod, a fence head is fixedly installed on the side of the soil turning parts, a buffer spring is provided between the plowing rod and the soil turning parts, and rollers are fixedly installed on both sides of the main frame.

[0018] By adopting the above technical solution, the partition plate can divide the inside of the material distribution box into two spaces, making it convenient for seeds and materials to be discharged separately, and the fence head can dig up the land to facilitate seed planting.

[0019] Furthermore, a plastic film storage rod is fixedly installed in the middle of the main frame, a protective frame is fixedly installed on the side of the main frame, a film-covering wheel is fixedly installed on the lower side of the protective frame, a buffer tube is fixedly installed on the front side of the main frame, and a soil-separating plate is fixedly installed at the lower end of the buffer tube.

[0020] By adopting the above technical solution, the operator can wrap the outer side of the plastic film storage rod with the film covering, and the film can be evenly laid on the upper side where the seeds and fertilizer have been set. The soil dividing board can pre-level the land.

[0021] Furthermore, the material distribution device includes a shock-absorbing spring fixedly installed at the lower end of the material distribution box, a linkage shaft fixedly installed in the middle of the shock-absorbing spring, a material distribution turntable fitted on the outer side of the linkage shaft, a plurality of slots being opened on the outer side of the material distribution turntable, and the linkage shaft being fixedly connected to the output end of the first drive motor.

[0022] By adopting the above technical solution, the first drive motor can drive the linkage shaft to rotate, and the linkage shaft will drive the material distribution turntable to rotate. Seeds and fertilizers can fall from the upper end of the shock-absorbing spring into the slot of the uniformly rotating material distribution turntable. When the slot carrying seeds or fertilizers moves to the lower side of the shock-absorbing spring, the seeds or fertilizers will fall into the interior of the discharge part under the action of gravity, thereby realizing regular material discharge.

[0023] Furthermore, the upper end of the seed tube has a metal folded structure, and the connection between the seed tube and the fertilizer hopper can be extended or retracted.

[0024] By adopting the above technical solution, it is possible to maintain a continuous connection between the seed tube and the fertilizer hopper for feeding when the seed tube moves up and down as a whole.

[0025] Furthermore, the inner cavity of the spreading pipe is provided with several fertilizer troughs in a ring, several shock-absorbing springs are fixedly installed at the lower end of the fertilizer pipe, shock-absorbing springs are provided between the fertilizer pipe and the seed tube, a discharge trough is provided at the lower end of the seed tube, and several through grooves are provided in a ring on the lower side of the fertilizer pipe.

[0026] By adopting the above technical solution, when the fertilizer pipe moves up and down back and forth, when the fertilizer pipe moves to the bottom, the through groove of the fertilizer pipe is connected to the fertilizer trough. At this time, the annular through groove will discharge material along the periphery of the fertilizer trough, thereby performing annular fertilization and increasing the overall fertilization area.

[0027] Compared with the prior art, the advantages of this invention are: 1. In this invention, by setting a structure with an outer tube sleeve for discharging material, and with nested fertilizer tubes and seed tubes inside, fertilizer and seeds can be spread separately, and waste can be scattered around the seeds for easy absorption by the seeds.

[0028] 2. In this invention, by setting up a structure with a control box and a spreading pipe, the fertilizer pipe is raised and lowered by reciprocating control. When the fertilizer pipe is lowered to the lowest point, fertilizer can be spread around the seeds through the fertilizer trough. When the discharge trough at the front end of the seed tube removes the soil surface, the fertilizer is dispersed. When the seed tube is raised, no fertilizer will pass through the fertilizer trough, which can effectively prevent fertilizer from contacting the seeds and causing seed burn.

The first drive motor 8 is electrically connected to the navigation vehicle body 2. A baffle plate 15 is fixedly installed on the middle side of the main frame 6. The motor inside the first drive motor 8 can be started and stopped by the navigation vehicle body 2, thereby controlling the discharge of seeds and fertilizer.

At this time, the ring through groove will discharge material along the periphery of the fertilizer trough 1901, thereby performing ring fertilization and increasing the overall fertilization area.

[0035] Working principle of the invention: The navigation vehicle body 2 is equipped with Beidou navigation and whole machine control device. It drives the main frame 6 and all working parts to move automatically along the preset working route through the metal connecting rod, realizing unmanned field operation. The rollers 4 on both sides of the main frame 6 support the whole machine to move. The buffer pipe 1301 on the front side of the main frame 6 drives the soil dividing plate 13 to move forward with the equipment to complete the pre-leveling operation of the field, and prepare for subsequent ditching and sowing. The inside of the material storage cylinder 3 is divided into two independent storage chambers by the isolation plate 7, which are used to store seeds and fertilizer respectively. The rotatable protective plate 1 at the top seals and protects the top of the material storage cylinder 3. The cleaning pipes 301 on both sides can be used to wash and maintain the inside of the material cylinder later. The navigation vehicle body 2 is electrically connected to the first drive motor 8. The discharge start and stop and the working rhythm of the whole machine are all uniformly controlled by the navigation vehicle body 2. The seeds and fertilizers in the storage cylinder 3 enter the first feeding box 11 and the second feeding box 1101 respectively, and are then transported to the inside of the distribution box 9 through the connecting pipe 12. The internal partition plate 901 of the distribution box 9 divides the cavity to prevent the seeds and fertilizers from mixing. The first drive motor 8 on the side of the distribution box 9 drives the linkage shaft 28 to rotate. The linkage shaft 28 drives the distribution turntable 27 to rotate synchronously. Seeds and fertilizers fall into the slots on the outer periphery of the distribution turntable 27. As the turntable continues to rotate, when the slot containing the material rotates to the lower position, the material falls downward into the inner cavity of the discharge part 14 by gravity, completing the quantitative and orderly distribution. The seeds falling into the discharge part 14 enter the fertilizer hopper 26, and are then conveyed downward through the retractable and foldable seed tube 22. 2. The upper metal folding structure can adapt to displacement changes, ensuring that the seed tube 22 remains connected to the fertilizer hopper 26 during its up-and-down movement. Fertilizer will fall into the discharge part 14 and enter the fertilizer tube 23. The plowing rod 17 drives the soil turning part 20 and the fence head 18 to open the soil trench. The buffer spring 16 between the plowing rod 17 and the soil turning part 20 buffers the trenching operation. Finally, the seeds are discharged from the discharge trough 24 at the lower end of the seed tube 22 into the opened soil trench, completing the fixed-point sowing. The second drive motor 32 inside the control box 29 drives the half gear 33 to rotate. The half gear 33 meshes and drives the reciprocating gear frame 31 to reciprocate linearly within the sliding frame 30. The reciprocating gear frame 31 is fixedly connected to the fertilizer pipe 23, thereby driving the fertilizer pipe 23 to slide up and down reciprocally within the discharge outer sleeve 21. When the fertilizer pipe 23 descends to its lower limit position, the annular groove at the lower end of the fertilizer pipe 23 connects with the fertilizer trough 1901 inside the spreading pipe 19. The fertilizer inside the fertilizer pipe 23 is discharged outward along the annular groove and fertilizer trough 1901, before being sown. A ring-shaped fertilizer layer is formed around the seeds, expanding the fertilization coverage area. When the fertilizer pipe 23 is raised, the channel and fertilizer trough 1901 are staggered and closed to stop fertilizer leakage. Fertilizer and seeds are applied at different times to avoid direct contact between fertilizer and seeds and prevent seed burning. After sowing and ring fertilization are completed, the plastic film wrapped on the plastic film storage rod 10 on the main frame 6 is led down. The plastic film passes around the covering wheel 5 below the protective frame 601. The covering wheel 5 lays the plastic film flat on the ground surface where sowing and fertilization have been completed, completing the entire sowing, fertilization and covering process.
