Description

Technical Field

[0001] This invention relates to the field of seeding equipment technology, and more specifically to an alternating continuous seeding device. Background Technology

[0002] Soil is a natural substance formed by the combined effects of parent material, climate, organisms, topography, and time. In different natural environments, the formation process and properties of soil vary. Soil possesses natural fertility and is the material basis for agricultural development and human survival.

[0003] Fertilization is the act of artificially supplementing plants with nutrients when the soil's nutrients are insufficient for their growth and development. The main function of fertilization is to provide plants with nutrients such as nitrogen, phosphorus, and potassium, which is an important measure to ensure rapid vegetation growth. Applying fertilizer to the soil can supplement the nutrients needed for crop growth and development, thereby improving crop quality and yield.

[0004] Existing fertilization methods cannot be tailored to the actual soil conditions; they generally rely on human judgment, which can lead to either excessive or insufficient nutrient supply. Excessive nutrient supply wastes fertilizer resources and may cause crop poisoning or even death. Conversely, insufficient nutrient supply reduces crop quality and leads to significant yield losses. Given these shortcomings, it is necessary to design an alternating continuous sowing device. Summary of the Invention

[0016] Compared with the prior art, the technical solution provided by the present invention has at least the following technical effects or advantages: This invention uses a cylinder to push a movable plate to move, which in turn causes a connecting plate to swing.

The digging mechanism 1 and the digging mechanism 2 also reciprocate up and down, thereby enabling the digging mechanism 1 and the digging mechanism 2 to perform alternating and continuous soil loosening operations, which improves work efficiency. This invention uses cylinder four to push the detection box downwards, and detection probe one and detection probe two also move downwards, allowing them to insert into the soil. The trace element sensor and nitrogen, phosphorus, and potassium sensor detect the content of nitrogen, phosphorus, potassium, and trace elements in the soil, and transmit the detected soil data to the microprocessor. The microprocessor compares and analyzes the detected soil data, calculates the fertilizer ratio scheme, and outputs a control signal to the controller. The controller opens the flow valve to quantitatively introduce the required fertilizer into the dispensing box one. After being mixed evenly, the fertilizer is applied to the soil, reducing fertilizer waste and thus achieving precise fertilization and improving fertilizer utilization. This invention uses cylinder two to drive shaft three to rotate, shaft three to drive sprocket four to rotate, and chain three to drive sprocket one to rotate, which in turn drives shaft one to rotate. This causes the tilting plate one and the covering plate one to swing, allowing fertilizer to be distributed into the soil in the feeding chamber. This enables simultaneous sowing and fertilization, improving work efficiency. After the fertilizer falls into the soil, the covering plate one can cover the fertilizer surface with soil, effectively isolating the fertilizer and seeds and preventing seedling burn from contact. This invention uses cylinder two to drive a rotating arm to swing, which in turn drives shaft three to rotate. Shaft three then drives tilting plate two and soil covering plate two to swing, causing the seeds in the feeding chamber to fall into the soil. After the seeds fall into the soil, cylinder two moves to reset tilting plate two, and soil covering plate two can cover the seed surface with soil. This operation is convenient and does not require manual additional soil sealing. Attached Figure Description

[0028] The soil testing mechanism 8 in this embodiment includes a trace element sensor 801 and a nitrogen, phosphorus, and potassium sensor 802. The trace element sensor 801 and the nitrogen, phosphorus, and potassium sensor 802 are installed in a testing box 803. The bottom of the trace element sensor 801 is electrically connected to a detection probe 804, and the bottom of the nitrogen, phosphorus, and potassium sensor 802 is electrically connected to a detection probe 805.

The controller is electrically connected to a hole-digging mechanism 2, a hole-digging mechanism 3, a drive mechanism 4, a fertilization mechanism 5, and a sowing mechanism 6.

[0029] Working principle of the invention: Soil testing: The seeds to be sown are poured into storage box 601. Nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, and trace element fertilizer are poured into several storage boxes respectively. Then, cylinder four 806 pushes the detection box 803 downward, and detection probe one 804 and detection probe two 805 also move downward, so that detection probe one 804 and detection probe two 805 are inserted into the soil. Trace element sensor 801 and nitrogen, phosphorus, potassium sensor 802 detect the content of nitrogen, phosphorus, potassium, and trace elements in the soil and transmit the detected soil data to the microprocessor. The microprocessor compares and analyzes the detected soil data and calculates the fertilizer ratio scheme, and outputs a control signal to the controller. The controller opens the flow valve 503 to quantitatively introduce the required fertilizer into the dispensing box one 504. After being mixed evenly, the fertilizer is applied to the soil, reducing fertilizer waste, thereby achieving precise fertilization and improving fertilizer utilization.

[0030] Alternating continuous soil loosening: When the tractor is started, the tractor drives the frame 1 to move. The motor 402 drives the gear 403 to rotate. The gear 403 drives the two racks 401 to move up and down. The digging mechanism 2 and the digging mechanism 3 also move up and down, thereby driving the digging mechanism 2 and the digging mechanism 3 to perform alternating continuous soil loosening operations, which improves work efficiency.

[0031] Fertilizer mixing: The controller opens the flow valve 503 to quantitatively introduce the required fertilizer into the dispensing box 504. After the fertilizer is introduced, the stirring motor 507 is turned on, driving the stirring shaft 506 to rotate. The stirring blades 505 also rotate, stirring the fertilizer in the dispensing box 504 to ensure uniform mixing. After the fertilizer is uniformly mixed, the motor 514 drives the gear 513 to rotate. The gear 513 drives the rack 512 to move, and the rack 512 drives the baffle plate 510 to move, so that the discharge hole 511 on the baffle plate 510 is aligned with the baffle. The discharge hole 509 on plate 508 is connected, so that the fertilizer in the distribution box 504 falls into the discharge funnel 517 through the discharge hole 509 and the discharge hole 511. The weighing sensor 521 weighs the fertilizer in the discharge funnel 517 and transmits the weight value to the microprocessor. The microprocessor analyzes the weight value detected by the weighing sensor 521. When the weight value detected by the weighing sensor 521 reaches the set value, the controller controls the motor 514 to rotate to reset and controls the solenoid valve 519 to open, so that the fertilizer in the discharge funnel 517 enters the discharge chamber.

[0032] Fertilization and soil covering: Cylinder 2 631 drives shaft 3 629 to rotate, shaft 3 629 drives sprocket 4 634 to rotate, chain 3 635 drives sprocket 1 529 to rotate, sprocket 1 529 drives shaft 1 528 to rotate, thereby causing the tilting plate 1 526 and the soil covering plate 1 527 to swing, so that the fertilizer in the feeding chamber is mixed with the soil, thus realizing simultaneous sowing and fertilization, improving work efficiency. After the fertilizer falls into the soil, the soil covering plate 1 527 can cover the fertilizer surface with soil, which can effectively isolate the fertilizer and seeds, and avoid seed and fertilizer contact, which can cause seedling burn.

[0033] Seed screening: Seeds in storage box 601 enter the feeding channel through discharge port 602. Compressed gas is generated by air compressor 608. The compressed gas enters the blower hood 606 through blow pipe 607 and is blown out from blow hole 604. Under the action of wind, qualified seeds will be blown away from screening plate 603 at a certain distance, and then continue to slide down the feeding channel to the bottom of the feeding channel under the action of gravity. Unqualified seeds (empty seeds) are blown away from screening plate 603 by wind due to their light weight and enter the waste collection drawer 609, thus realizing seed screening.

[0034] Sowing and Covering: Seeds in the feeding channel fall into feeding hole 3 614. Motor 2 514 drives gear 2 513 to rotate, gear 2 513 drives gear 3 523 to rotate, gear 3 523 drives shaft 2 624 to rotate, shaft 2 624 drives sprocket 3 623 to rotate. Under the transmission of chain 2 622 and chain 1 621, the rotating cylinder 618 is driven to rotate, so that feeding hole 4 616 on the rotating cylinder 618 is connected to feeding hole 3 614 on baffle plate 3 613, so that the seeds in feeding hole 3 614 pass through feeding hole 4 615. The seeds fall into a groove 619 of the rotating cylinder 618. At the same time, the seeds in another groove 619 of the rotating cylinder 618 fall into the feeding chamber. The cylinder 631 pushes the rotating arm 630 to swing. The rotating arm 630 drives the rotating shaft 629 to rotate. The rotating shaft 629 drives the tilting plate 627 and the covering plate 628 to swing, so that the seeds in the feeding chamber fall into the soil. After the seeds fall into the soil, the cylinder 631 moves to reset the tilting plate 627. The covering plate 628 can cover the soil on the surface of the seeds. This operation is convenient and does not require manual additional soil sealing.
