Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology, specifically to a quantitative sowing device for intelligent agricultural planting. Background Technology

[0002] Agriculture, as a fundamental industry of the national economy, directly impacts food security and agricultural economic development through its production efficiency and planting quality. With advancements in modern agricultural technology, traditional manual sowing methods, hampered by low efficiency, high labor intensity, and poor precision, are no longer sufficient to meet the demands of large-scale, precision agriculture. Quantitative seeding equipment, as core equipment for improving sowing quality and efficiency, is gradually becoming a crucial support for agricultural production. Quantitative seeding equipment can precisely control the amount of seeds sown per hill according to crop growth needs, not only avoiding seed waste but also ensuring uniform crop emergence, laying the foundation for subsequent field management and high yields. It is particularly widely used in the cultivation of cash crops such as corn, soybeans, and vegetables.

[0003] Currently, quantitative seeding equipment on the market is mainly divided into two categories: mechanical quantitative seeding and electronic quantitative seeding. Electronic quantitative seeding equipment relies on electronic components such as sensors and controllers to control the seeding rate. Although it can improve accuracy to a certain extent, it has problems such as high manufacturing cost, electronic components being easily affected by field moisture and dust, resulting in failure, and high maintenance difficulty. It is not suitable for small-scale growers or complex field scenarios. Mechanical quantitative dispensing equipment is more widely used due to its simple structure and low cost, but it still has many technical defects: First, the quantitative accuracy is insufficient. Traditional mechanical dispensing mechanisms mostly use fixed-volume storage structures, and the seed size difference or residue can easily lead to deviations in the amount of seeds sown per hole. Although some equipment attempts to use elastic components to assist in dispensing, it still cannot completely solve the problem of material residue. Second, the coordination of operation links is poor. The feeding, dispensing, and irrigation of existing equipment are mostly independent operations. The feeding mechanism is prone to blockage due to seed clumping, requiring frequent manual cleaning. Irrigation is mostly continuous water supply, which cannot be accurately matched with the sowing action, resulting in water waste or seed dehydration affecting germination. Third, power control and maintenance are inconvenient. The power transmission system of most equipment is decentralized, requiring operators to frequently switch operating positions. Emergency response is slow, and the equipment components are mostly fixed connections, making disassembly and maintenance time-consuming. When it is necessary to replace the components to adapt to different crops, the operation is cumbersome. Fourth, the seed protection performance is insufficient. Seeds are easily broken due to high-speed impacts on mechanical components during the falling and dispensing process, especially for larger seeds, which affects the germination rate. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a quantitative seeding device for intelligent agricultural planting, which solves the problems mentioned in the background art.

[0005] The solution of the present invention to the above-mentioned technical problems is as follows: This invention provides a quantitative seeding device for intelligent agricultural planting, comprising: A chassis on which an engine and a clutch-brake reducer connected to the engine are mounted; The clutch brake reducer is connected to an intermediate transmission rod. The quantitative dispensing mechanism is connected to the clutch brake reducer via the intermediate transmission rod. Several storage hoppers are mounted on the frame and located above the quantitative dispensing mechanism; A feeding and irrigation assembly, which is mounted on the frame and located on one side of the storage hopper; A liquid storage tank, which is mounted on one side of the vehicle frame; A push rod is mounted at the end of the frame, and a push handle is provided at the end of the push rod; Wheels, which are rotatably mounted at the bottom end of the frame; A trenching blade and a soil covering device are mounted at the bottom end of the vehicle frame; The quantitative dispensing mechanism includes a rotating shaft, a transmission wheel installed at one end of the rotating shaft, and a turntable and a dispensing disc installed on the rotating shaft, wherein the turntable and the dispensing disc are distributed crosswise on the rotating shaft; The material guiding and irrigation components are linked with the turntable to guide the material in the storage hopper and achieve intermittent feeding, while also being able to quantitatively discharge the liquid in the storage tank for irrigation.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, storage troughs are evenly provided on the outer side of the material distribution plate, and movable lining tiles are installed inside the storage troughs; A limiting groove is provided in the material distribution plate, and a first connecting rod extending into the limiting groove is connected to the bottom end of the lining tile. The first link is provided with two limiting blocks to limit the movement distance of the first link; A mass block is fitted onto the first connecting rod between the two limiting blocks; The liner and the mass block are configured to move under their own weight, such that when the storage trough rotates to the top, the liner retracts to receive material, and when the storage trough rotates to the bottom, the liner extends to push material, while the mass block strikes a limiting block to cause the liner to vibrate.

[0008] The beneficial effects of adopting the above-mentioned further solutions are: This improvement achieves fully automated control of seed quantity measurement through the synergistic effect of a purely mechanical structure and gravity, eliminating the need for additional sensors or drive components and effectively reducing equipment manufacturing costs and failure risks. The limiting block precisely constrains the movement distance of the first connecting rod, ensuring stable extension and contraction of the liner and preventing insufficient material reception or incomplete material pushing due to excessive liner movement. The impact design of the mass block and the limiting block shakes off seeds adhering to the inner wall of the storage trough through vibration, completely solving the quantitative deviation problem caused by material residue in traditional dispensing mechanisms and reducing the consistency error of seeding per hole. Furthermore, this structure is highly adaptable; by replacing liner thicknesses or adjusting the weight of the mass block, it can meet the seeding needs of crops with different particle sizes and specific gravities, expanding the equipment's applicability.

[0009] Furthermore, a housing is installed on the outside of the material distribution plate on the rotating shaft, and the housing is connected and fixed to the vehicle frame by bolts; The top of the outer shell is connected to the bottom of the storage hopper, and the bottom of the outer shell is provided with a discharge port, which is located between the grooving blade and the intermediate transmission rod.

[0010] The beneficial effects of adopting the above-mentioned further solutions are: The outer shell provides a closed working space for the distributing tray, effectively preventing external dust, weeds, and other impurities from entering the distributing mechanism. This avoids jamming of transmission components and seed contamination, extending the equipment's service life. The bolted connection facilitates the disassembly and assembly of the outer shell. When the distributing mechanism malfunctions or requires cleaning and maintenance, operators can quickly disassemble the shell for handling, reducing maintenance difficulty and time costs. The specific design of the discharge port ensures that seeds, after being discharged, fall directly into the pre-dug trenches by the furrowing blade, preventing seeds from scattering outside the trenches, reducing seed waste, shortening the seed fall path, reducing sowing position deviation caused by environmental factors such as wind, and improving sowing accuracy.

[0011] Furthermore, the bottom end of the storage hopper is provided with a guide hopper, and the storage hopper is connected to the outer shell through the guide hopper.

[0012] The beneficial effects of adopting the above-mentioned further solutions are: The funnel-shaped design of the feed hopper creates a gradual discharge channel from the storage hopper to the outer shell, effectively collecting seeds within the hopper and preventing seed accumulation and blockage at the bottom outlet, ensuring a continuous and stable seed supply. Simultaneously, the constricting structure of the feed hopper cushions the falling seeds, slowing their descent and preventing breakage due to high-speed impact with the distribution plate. This is particularly suitable for planting larger seeds such as corn and soybeans, reducing seed breakage rates. Furthermore, the independent design of the feed hopper facilitates individual disassembly and cleaning, preventing cross-contamination between different batches of seeds and improving the hygiene of the equipment.

[0013] Furthermore, the material guiding and irrigation assembly includes a guide plate, on which a top rod is installed through; The bottom end of the top rod is provided with guide rods on both sides, and the guide rods slide in conjunction with the grooves opened on the turntable; The top end of the top rod is connected to a mounting plate, and the mounting plate is evenly distributed with second connecting rods. The bottom end of the second connecting rod is connected to a conical material feeding head that extends into the guide hopper. An irrigation cylinder is also installed on the top rod.

[0014] The beneficial effects of adopting the above-mentioned further solutions are: This improvement achieves mechanical linkage between material guiding, seeding, and irrigation, enabling multi-stage collaborative operation without an additional power source, significantly improving equipment integration and operational efficiency. When the turntable rotates, the sliding engagement of the groove and guide rod drives the push rod to perform a stable reciprocating lifting motion along the guide plate. The guide plate provides guidance and constraint for the push rod, preventing deviation in material guiding and irrigation actions caused by push rod swaying. The conical material guiding head extends into the material hopper, and its reciprocating motion effectively breaks up seed clumps. Simultaneously, the conical structure reduces pressure damage to the seeds, ensuring smooth material flow. The integrated design of the push rod and irrigation cylinder ensures precise synchronization between irrigation and material guiding actions, preventing problems such as sowing before water shortage or irrigating before missed sowing, providing optimal water-material matching conditions for seed germination.

[0015] Furthermore, the irrigation cylinder includes a cylinder body, and a partition is provided inside the cylinder body, which evenly divides the cylinder body into multiple liquid storage chambers; Each of the liquid storage chambers is connected to a liquid inlet connector and a liquid outlet connector. A sealing plate is installed on the top rod in each of the liquid storage chambers.

[0016] The beneficial effects of adopting the above-mentioned further solutions are: The partition divides the irrigation cylinder into multiple independent liquid storage chambers, each corresponding to a single sowing position, enabling precise irrigation of each sowing hole and avoiding the uneven irrigation caused by traditional monolithic irrigation. The sealing plate and the liquid storage chambers work together to form a piston-like structure. When the push rod moves the sealing plate up and down, the volume change of each individual liquid storage chamber can be precisely controlled, thus achieving quantitative adjustment of the irrigation amount. Operators can adapt to the water requirements of different crop seeds by replacing sealing plates of different thicknesses or adjusting the stroke of the push rod. The parallel design of multiple liquid storage chambers also ensures the continuity of irrigation operations. When some liquid storage chambers are absorbing liquid, other liquid storage chambers are simultaneously draining liquid, making the irrigation process uninterrupted and improving operational efficiency.

[0017] Furthermore, the inlet connector is connected to the storage tank via a one-way valve, and the outlet connector is connected to the irrigation conduit via a one-way valve.

[0018] The beneficial effects of adopting the above-mentioned further solutions are: The one-way valves create a unidirectional flow path for the liquid. The one-way valve at the inlet allows only liquid from the storage tank to flow into the storage chamber, preventing backflow of liquid from the storage chamber when pressure changes occur, thus ensuring sufficient liquid absorption in the storage chamber. The one-way valve at the outlet allows only liquid from the storage chamber to drain into the irrigation conduit, avoiding backflow in the irrigation conduit that could cause irrigation volume deviations. It also prevents impurities in the soil from entering the storage chamber through the irrigation conduit, causing equipment blockage. The synergistic effect of the two-way one-way valves ensures that the liquid absorption and drainage processes of each storage chamber are independent and precisely controllable, significantly improving the stability and reliability of the irrigation system and reducing errors in irrigation volume per cycle.

[0019] Furthermore, the clutch brake reducer is also connected to a pull rod for transmission.

[0020] The beneficial effects of adopting the above-mentioned further solutions are: The lever provides operators with a convenient power control interface. Operators can directly control the clutch and brake states of the clutch and brake reducer by manipulating the lever near the push handle, enabling rapid start-up, shutdown, and speed adjustment of the equipment. This eliminates the need for frequent trips to the engine control unit, significantly improving operational convenience and safety. When the equipment encounters obstacles such as rocks or weeds during operation, operators can quickly cut off power using the lever, preventing damage to components such as the material distribution mechanism and trenching blades due to overload. This also prevents accidents caused by equipment malfunction, providing dual protection for both the equipment and the operator.

[0021] Therefore, the present invention provides a quantitative seeding device for intelligent agricultural planting. It has the following beneficial effects: 1. A movable liner and a matching first connecting rod, mass block, and limiting block structure are installed in the storage trough of the quantitative seed dispensing mechanism. Utilizing the gravity characteristics of the liner and mass block, dynamic coordinated action is achieved. When the storage trough rotates to the upper position for receiving material, the liner naturally retracts to maximize the storage space and ensure stable material receiving. When the storage trough rotates to the lower position for dispensing, the liner extends to push the material, while the mass block impacts the limiting block, causing the liner to vibrate, completely preventing seed residue in the storage trough. This gravity-driven and vibration-assisted composite quantitative structure achieves precise control of the entire process of seed receiving, pushing, and trough cleaning without an additional power source. It effectively solves the seeding deviation problem caused by mechanical jamming and material residue in traditional equipment, keeping the single-hole seeding error within a very small range. This provides a fundamental guarantee for the consistency of subsequent crop growth, and is especially suitable for economic crop planting scenarios with high seeding accuracy requirements.

[0022] 2. The sliding cooperation design of the turntable and the top rod enables a mechanical linkage between the quantitative seeding mechanism and the material guiding and irrigation components: During the rotation of the turntable, its sliding groove drives the top rod to rise and fall along the guide plate. The conical material dispensing head at the top of the top rod reciprocates synchronously within the material guiding hopper, effectively breaking up material lumps and preventing blockage of the storage hopper, ensuring a continuous seed supply. Simultaneously, the top rod drives the sealing plate inside the irrigation cylinder to move. Through the periodic change of the liquid storage chamber volume and the cooperation of the one-way valve, quantitative suction and discharge of liquid in the storage tank are achieved, making irrigation and seeding operations precisely synchronized. This integrated linkage design of material guiding, seeding, and irrigation combines the independent operation links of traditional equipment into a continuous process, reducing equipment operation steps and matching irrigation volume with seeding volume, thus avoiding water waste.

[0023] 3. The clutch-brake reducer serves as the core power source. One end connects to the engine drive, while the other end simultaneously drives the intermediate transmission rod and pull rod, achieving centralized power distribution and precise control. The integrated design of the clutch-brake reducer allows for rapid power cut-off or transmission during startup, shutdown, and speed adjustment, avoiding transmission conflicts common in traditional multi-power source equipment. Simultaneously, the intermediate transmission rod stably transmits power to the quantitative dispensing mechanism, ensuring uniform rotation speed of the turntable and dispensing disc, providing power assurance for quantitative accuracy. Furthermore, the push handle at the end of the equipment, in conjunction with the wheels, allows operators to easily move the equipment. Combined with the integrated design of the trenching blade and covering device, it enables the entire process of trenching, sowing, irrigation, and covering without the need for additional auxiliary equipment, reducing operator workload and enhancing the equipment's adaptability to small plots or complex terrain.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1 to 9 As shown, the embodiments provided by the present invention are as follows: Example 1: A quantitative seeding device for intelligent agricultural planting, comprising: The frame 1 is equipped with an engine 7 and a clutch brake reducer 701 that is connected to the engine 7 in a transmission. The clutch brake reducer 701 has an intermediate transmission rod 103 in its transmission connection; The quantitative dispensing mechanism 2 is connected to the clutch brake reducer 701 via the intermediate transmission rod 103. Several storage hoppers 6 are mounted on the frame 1 and located above the quantitative dispensing mechanism 2; The material guiding and irrigation component 5 is mounted on the frame 1 and located on one side of the storage hopper 6; Liquid storage tank 4 is installed on one side of the frame 1; Push rod 3 is installed at the end of frame 1, and push handle 301 is provided at the end of push rod 3; Wheel 101, which is rotatably mounted at the bottom end of frame 1; The trenching blade 102 and the soil covering device 104 are mounted at the bottom end of the frame 1; The quantitative dispensing mechanism 2 includes a rotating shaft 205, a transmission wheel 201 installed at one end of the rotating shaft 205, and a turntable 203 and a dispensing disc 206 installed on the rotating shaft 205. The turntable 203 and the dispensing disc 206 are distributed crosswise on the rotating shaft 205. The material guiding and irrigation component 5 is linked with the turntable 203 to guide the material in the storage hopper 6 and realize intermittent feeding. At the same time, it can quantitatively push out the liquid in the liquid storage tank 4 for irrigation.

[0029] Example 2: To further improve the accuracy of quantitative seed sowing, and to optimize the protection and maintenance performance of the dispensing mechanism, reducing seed breakage rate and equipment failure risk, for example, such as... Figures 1 to 9 As shown, the present invention also includes: The outer side of the material distribution plate 206 is evenly provided with material storage troughs 209, and movable lining tiles 210 are installed in the material storage troughs 209. A limiting groove 211 is provided in the material distribution plate 206, and a first connecting rod 208 extending into the limiting groove 211 is connected to the bottom end of the lining tile 210. The first link 208 is provided with two limiting blocks 212 to limit the movement distance of the first link 208; A mass block 207 is fitted on the first connecting rod 208 between the two limiting blocks 212; The liner 210 and the mass block 207 are configured to move under their own gravity. When the storage trough 209 rotates to the top, the liner 210 retracts to receive the material; when the storage trough 209 rotates to the bottom, the liner 210 extends to push the material. Simultaneously, the mass block 207 impacts a limiting block 212, causing the liner 210 to vibrate. This improvement achieves fully automated control of seed quantity through the synergistic effect of a purely mechanical structure and gravity, eliminating the need for additional sensors or drive components and effectively reducing equipment manufacturing costs and failure risks. The limiting block 212 precisely constrains the movement distance of the first connecting rod 208, ensuring stable extension and retraction of the liner 210 and avoiding insufficient material reception or incomplete pushing due to excessive movement of the liner 210. The impact design of the mass block 207 and the limiting block 212 can shake off the seeds adhering to the inner wall of the storage trough 209 through vibration, completely solving the quantitative deviation problem caused by material residue in traditional dispensing mechanisms and reducing the consistency error of seeding per hole. Meanwhile, the structure is highly adaptable. By replacing the lining tiles 210 with different thicknesses or adjusting the weight of the mass block 207, it can meet the sowing needs of crop seeds with different particle sizes and specific gravities, thus expanding the applicability of the equipment.

[0030] A housing 202 is installed on the outside of the material distribution plate 206 on the rotating shaft 205. The housing 202 is connected and fixed to the frame 1 by bolts. The top of the outer casing 202 is connected to the bottom of the storage hopper 6, and its bottom is provided with a discharge port 204. The discharge port 204 is located between the trenching blade 102 and the intermediate transmission rod 103. The outer casing 202 provides a closed working space for the distribution plate 206, which can effectively prevent external dust, weeds and other impurities from entering the distribution mechanism, avoid jamming of transmission components and seed contamination, and extend the service life of the equipment. The bolt connection method facilitates the disassembly and assembly of the outer casing 202. When the distribution mechanism malfunctions or needs cleaning and maintenance, the operator can quickly disassemble the outer casing 202 for handling, reducing maintenance difficulty and time costs. The specific position design of the discharge port 204 allows the seeds to fall directly into the trench pre-dug by the trenching blade 102 after being discharged from the discharge port 204, preventing the seeds from scattering outside the trench, reducing seed waste, and shortening the seed falling path, reducing the problem of seeding position deviation caused by environmental factors such as wind, and improving seeding accuracy.

[0031] The bottom of the storage hopper 6 is equipped with a guide hopper 601, which connects the storage hopper 6 to the outer casing 202. The guide hopper 601 has a funnel-shaped design, creating a gradual discharge channel from the storage hopper 6 to the outer casing 202. This effectively collects the seeds within the storage hopper 6, preventing seed accumulation and blockage at the bottom outlet and ensuring a continuous and stable seed supply. Simultaneously, the retractable structure of the guide hopper 601 buffers the falling seeds, slowing their descent and preventing breakage due to high-speed impact with the distribution plate 206. This is particularly suitable for planting larger seeds such as corn and soybeans, reducing seed breakage rates. Furthermore, the independent design of the guide hopper 601 facilitates individual disassembly and cleaning, preventing cross-contamination between different batches of seeds and improving the hygiene of the equipment.

[0032] Example 3: To achieve integrated control of material feeding, sowing, and irrigation operations, improve equipment operating efficiency and resource utilization efficiency, and ensure precise matching of irrigation volume and sowing requirements, for example, Figures 1 to 9 As shown, the present invention also includes: The feeding and irrigation assembly 5 includes a guide plate 507, on which a top rod 511 is installed through; The bottom end of the top rod 511 is provided with guide rods 512 on both sides, and the guide rods 512 slide in conjunction with the grooves 213 opened on the turntable 203; The top end of the top rod 511 is connected to the mounting plate 506, and the mounting plate 506 is evenly distributed with second connecting rods 505. The bottom end of the second connecting rod 505 is connected to a conical material feeding head 504 that extends into the guide hopper 601. An irrigation cylinder 503 is also installed on the top rod 511. This improvement realizes the mechanical linkage of material guiding, seeding and irrigation, and can complete multi-stage collaborative operation without an additional power source, greatly improving the integration of equipment and operating efficiency. When the turntable 203 rotates, it drives the top rod 511 to make a stable reciprocating up and down movement along the guide plate 507 through the sliding cooperation of the slide groove 213 and the guide rod 512. The guide plate 507 provides guidance and constraint for the top rod 511 to avoid the deviation of material dispersing and irrigation actions caused by the shaking of the top rod 511. The conical material dispersing head 504 extends into the material guide hopper 601. Its up and down reciprocating movement can effectively break up seed clumps. At the same time, the conical structure can reduce the squeezing damage to the seeds and ensure smooth material dispensing. The integrated design of the top rod 511 and the irrigation cylinder 503 makes the irrigation action and the material guiding action precisely synchronized, avoiding the problem of water shortage after sowing or missed sowing after irrigation, and providing the best water and material matching conditions for seed germination.

[0033] The irrigation cylinder 503 includes a cylinder 508, and a partition 513 is provided inside the cylinder 508. The partition 513 evenly divides the inside of the cylinder 508 into multiple liquid storage chambers 510. Each liquid storage chamber 510 is connected to a corresponding liquid inlet connector 501 and a liquid outlet connector 502. Each liquid storage chamber 510 on the top rod 511 is equipped with a sealing plate 509. A partition 513 divides the irrigation cylinder 503 into multiple independent liquid storage chambers 510, each corresponding to a sowing position, achieving a precise irrigation mode of one-hole-one-irrigation, avoiding the uneven irrigation caused by traditional integrated irrigation. The cooperation between the sealing plate 509 and the liquid storage chamber 510 forms a piston-like structure. When the top rod 511 moves the sealing plate 509 up and down, the volume change of a single liquid storage chamber 510 can be precisely controlled, thereby achieving quantitative adjustment of the irrigation amount. Operators can adapt to the water requirements of different crop seeds by replacing sealing plates 509 of different thicknesses or adjusting the stroke of the top rod 511. The parallel design of multiple liquid storage chambers 510 also ensures the continuity of irrigation operations. When some liquid storage chambers 510 are absorbing liquid, other liquid storage chambers 510 are simultaneously discharging liquid, making the irrigation process uninterrupted and improving operational efficiency.

[0034] The inlet connector 501 is connected to the storage tank 4 via a one-way valve, and the outlet connector 502 is connected to the irrigation conduit via a one-way valve. The one-way valves create a unidirectional flow channel for the liquid. The one-way valve at the inlet connector 501 only allows liquid from the storage tank 4 to flow into the storage chamber 510, preventing backflow of liquid from the storage chamber 510 to the storage tank 4 when pressure changes, ensuring sufficient liquid absorption in the storage chamber 510. The one-way valve at the outlet connector 502 only allows liquid from the storage chamber 510 to drain into the irrigation conduit, avoiding backflow of liquid from the irrigation conduit and preventing impurities in the soil from entering the storage chamber 510 through the irrigation conduit, thus preventing equipment blockage. The synergistic effect of the two-way one-way valves makes the liquid absorption and drainage processes of each storage chamber 510 independent and precisely controllable, significantly improving the stability and reliability of the irrigation system and reducing errors in the amount of liquid absorbed each time.

[0035] Example 4: To optimize the convenience of equipment power control and emergency response capabilities, improve operator safety, and reduce the risk of equipment overload damage, for example, such as Figures 1 to 9 As shown, the present invention also includes: The clutch-brake reducer 701 is also connected to a pull rod 702, which provides a convenient power control interface for the operator. The operator can directly control the clutch and brake states of the clutch-brake reducer 701 by manipulating the pull rod 702 near the push handle 301, realizing rapid start-up, shutdown, and speed adjustment of the equipment. This eliminates the need for frequent trips to the engine 7 operating end, greatly improving operational convenience and safety. When the equipment encounters obstacles such as rocks or weeds during operation, the operator can quickly cut off the power through the pull rod 702 to prevent damage to components such as the material distribution mechanism and trenching blade 102 due to overload, while also preventing safety accidents caused by equipment loss of control, providing dual protection for both the equipment and the operator.

[0036] Working principle: After the equipment is started, the engine 7 begins to run and transmits power to the clutch-brake reducer 701. As the core of power distribution, the clutch-brake reducer 701 drives the intermediate transmission rod 103 to rotate, providing power to the quantitative dispensing mechanism 2; on the other hand, it also drives the pull rod 702 to move, realizing flexible control and transmission switching of the equipment's power, ensuring that each actuator starts as needed.

[0037] When the intermediate transmission rod 103 rotates, it synchronously drives the rotating shaft 205 of the quantitative seeding mechanism 2 to rotate. The transmission wheel 201 on the rotating shaft 205 is also linked, ensuring that the entire seeding mechanism and the power system maintain a stable transmission ratio. During the rotation of the rotating shaft 205, the turntables 203 and the material distribution plate 206 distributed on it rotate synchronously, preparing for the mechanical linkage of subsequent material distribution, guiding, and irrigation actions. At this time, the storage trough 209 on the outside of the material distribution plate 206 rotates with the material distribution plate 206, and the lining tile 210 and the mass block 207 in the storage trough 209 are in the initial waiting state under their own gravity.

[0038] When the turntable 203 rotates, the groove 213 on its surface slides into contact with the guide rod 512 at the bottom of the top rod 511 in the material guiding and irrigation assembly. The trajectory of the groove 213 drives the guide rod 512 to move up and down reciprocally, thereby causing the top rod 511 to move vertically up and down along the guide plate 507. The mounting plate 506 at the top of the top rod 511 moves up and down synchronously with the top rod 511, driving the second connecting rod 505 and the connected conical discharge head 504 on the mounting plate 506 to move up and down within the material guide hopper 601. The reciprocating motion of the conical discharge head 504 effectively prevents the material in the storage hopper 6 from clumping and blocking at the material guide hopper 601, ensuring that the material can flow smoothly to the dispensing mechanism and providing a continuous and stable material supply for quantitative dispensing.

[0039] When the storage trough 209 on the distributing plate 206 rotates to the upper position, the lining tile 210 inside the storage trough 209 retracts under its own gravity. At this time, the storage hopper 6 is connected to the outer shell 202 of the distributing mechanism through the guide hopper 601. The material enters the interior of the outer shell 202 through the guide hopper 601 and falls precisely into the storage trough 209, which is in a waiting state, completing the quantitative feeding. As the distributing plate 206 continues to rotate, when the storage trough 209 containing material rotates to the lower position, the lining tile 210 extends under its own gravity and the pressure of the material, pushing the material in the storage trough 209 downward. At the same time, the mass block 207 strikes the lower limiting block 212 under the action of gravity, causing the lining tile 210 to vibrate. This vibration ensures that the material in the storage trough 209 completely detaches from the lining tile 210 and the storage trough 209, avoiding residue and achieving precise quantitative feeding. The material finally falls into the prepared trench through the discharge port 204 at the bottom of the outer shell 202, completing the core step of quantitative seeding.

[0040] During the lifting and lowering of the top rod 511 in conjunction with the turntable 203, the irrigation cylinder 503 installed on its outer side moves synchronously. The cylinder body 508 of the irrigation cylinder 503 is divided into multiple independent liquid storage chambers 510 by a partition 513. The sealing plate 509 located in each liquid storage chamber 510 on the top rod 511 moves up and down with the top rod 511 to control the volume of the liquid storage chamber 510. When the top rod 511 rises, the sealing plate 509 moves upward, increasing the volume of the liquid storage chamber 510. The liquid in the liquid storage tank 4 enters the inlet connector 501 through the one-way valve and finally flows into the liquid storage chamber 510 to complete the liquid absorption. When the top rod 511 falls, the sealing plate 509 moves downward, compressing the volume of the liquid storage chamber 510. The liquid in the chamber is then forced into the irrigation conduit through the outlet connector 502 and the one-way valve, and accurately delivered to the sowing position, realizing quantitative irrigation synchronous with sowing and providing suitable moisture conditions for seed germination.

[0041] The equipment moves via wheels 101 under propulsion. During movement, the ditching blade 102 at the bottom of the frame 1 creates planting trenches on the ground before the feeding port 204, ensuring precise material placement. After feeding and irrigation, the soil covering device 104 at the bottom of the frame 1 covers the seed-filled trenches with soil, completing the planting process. Throughout the process, the clutch-brake reducer 701 controls the on / off state and transmission speed of power, coordinating the rhythm of each step, including ditching, feeding, irrigation, and soil covering, to achieve continuous and efficient quantitative sowing operations.

[0042] When it is necessary to stop the operation, the power transmission from the engine 7 to each actuator is cut off by the clutch brake reducer 701. The intermediate transmission rod 103, turntable 203, material distribution plate 206 and other components stop operating, the material guiding and irrigation actions are terminated simultaneously, and the equipment completes a single operation cycle or stops to standby.
