Description

Technical Field

[0001] This invention relates to the field of agricultural seeding machinery technology, and in particular to a precision seeding device for soaking, germinating, and breaking down wheat seeds. Background Technology

[0002] Wheat is a major grain crop in my country, with a wide planting area and a large planting volume, occupying a core position in the agricultural production system. In order to improve the emergence rate, seedling growth and later stress resistance of wheat, wheat seeds are generally subjected to soaking, germination and seed coat cracking pretreatment operations in agricultural production. After this process, the radicle of the seed will initially germinate and the seed coat will crack, resulting in faster emergence and higher uniformity of emergence. However, such germinated and seed coat cracked wheat seeds have characteristics such as tender buds, softened seed coat, high seed moisture content and easy adhesion and clumping of seeds, which puts forward special requirements for the seed conveying and seed metering structure of the sowing equipment. Existing precision wheat seeding equipment typically uses rigid rollers, scrapers, and straight-bladed spiral structures to forcibly push seeds. However, the fragile texture of germinated wheat seedlings makes them highly susceptible to breakage and embryo damage during squeezing, impact, and scraping, directly causing seed inactivation and significantly reducing field emergence rates. This greatly diminishes the effectiveness of the initial soaking and germination process. Furthermore, the moistened and sticky surface of soaked wheat seeds makes them prone to clumping together and getting stuck in pipes, discharge ports, and leaf gaps, frequently leading to material interruptions and blockages. Therefore, there is an urgent need for a precision wheat seeding device that involves soaking, germinating, and breaking the seed coat. Summary of the Invention

[0008] Preferably, the bottom of the trolley frame is fixedly provided with two support columns, the surface of the trolley frame and the horizontal frame is fixedly provided with a pusher, a battery is fixedly provided on the trolley frame, a control switch is fixedly provided on the top of the battery, and multiple power transmission lines are electrically connected to the battery, the control switch and the servo motor.

[0009] Preferably, the axial direction of the central rod, the axial direction of the diverter cylinder, and the axial direction of the discharge cylinder are coaxially arranged. The ends of the two discharge cylinders are respectively movably sleeved on both ends of the diverter cylinder, and the ends of the two discharge cylinders are respectively movably sleeved on both ends of the support cylinder. The support cylinder is movably sleeved on the periphery of the diverter cylinder.

[0010] Preferably, the two ends of the diverter are respectively movably sleeved around the two small spiral blades, the two small spiral blades have opposite spiral directions, the two small spiral blades are located directly below the conveying pipe, and the other end of the conveying pipe is located directly above the interface.

[0017] Reference Figures 1 to 9 A precision sowing device for soaked, germinated, and chest-breaking wheat seeds includes: a trolley frame 1, with a horizontal frame 3 fixedly mounted on top of the trolley frame 1; the trolley frame 1 serves as the basic load-bearing frame of the entire machine, and the horizontal frame 3 is horizontally fixed to the top of the trolley frame 1. The two work together to provide a stable installation benchmark and load-bearing platform for the feeding mechanism, sowing mechanism, and electrical components. The overall structure has high strength and can be adapted to complex field road conditions; a sowing mechanism, which is fixedly mounted on the trolley frame 1; this mechanism is the core operating unit, specifically designed for soaked, germinated, and chest-breaking wheat seeds, and can complete the entire process of centralized distribution, step-by-step quantitative conveying, and fixed-point uniform sowing of wheat seeds in the field, effectively avoiding damage to the buds and achieving standardized precision sowing; and a feeding mechanism, which is fixedly mounted on the horizontal frame 3; this mechanism is a pre-feeding unit that can centrally store wheat seeds and rely on power components to achieve intermittent, equal-volume, and uniform feeding of wheat seeds, continuously and stably conveying materials to the sowing mechanism below, eliminating problems of material interruption, material accumulation, and material blockage.

[0018] In this invention, the sowing mechanism includes: a support cylinder 5, the outer surface of which is fixedly mounted on the side of the trolley frame 1; the support cylinder 5 is a cylindrical closed shell, serving as the main protective and load-bearing outer shell of the sowing mechanism, housing all components for diversion, seed conveying, and rotation, while preventing soil and debris from entering the cavity and protecting the internal precision transmission and seed conveying components; bearings 51, at least two bearings 51 respectively fitted at both ends of the support cylinder 5; the bearings 51 adopt a rotating fit structure, providing radial positioning and rotational support for the discharge cylinder 55, significantly reducing the mechanical friction resistance when the discharge cylinder 55 rotates, ensuring that the discharge cylinder 55 operates flexibly, without jamming, and with low noise for a long time.

[0019] In this invention, multiple fixed rods 52 are fixed at one end to the inner wall of the support cylinder 5. The multiple fixed rods 52 are evenly distributed in a ring, suspending the diverting cylinder 53 inside the support cylinder 5. While ensuring a firm connection, sufficient space is reserved for the flow of wheat seeds and the rotation of components, without interfering with material conveying and structural operation. The diverting cylinder 53 is fixed at the other end of the multiple fixed rods 52 on its outer surface. The diverting cylinder 53 receives the wheat seeds conveyed from above, centrally collects the scattered wheat seeds, and then uses its internal space to evenly guide the wheat seeds to the left and right ends, completing the diversion from single-path feeding to dual-path discharging, ensuring a balanced discharge on both sides.

[0020] In this invention, two discharge cylinders 55 are respectively disposed through the middle of at least two bearings 51. The discharge cylinder 55 is a hollow tubular discharge channel that rotates synchronously with the movement of the equipment. The internal spiral blades push wheat seeds outward and discharge them. It is the last conveying channel for wheat seeds before they land and directly determines the sowing position and discharge state. Two large spiral blades 56 are respectively fixedly disposed on the inner walls of the two discharge cylinders 55. The large spiral blades 56 rotate synchronously with the discharge cylinders 55 and continuously push wheat seeds forward by relying on the spiral helix angle of the spiral blades. The number of seeds discharged at one time is precisely controlled by the blade pitch and rotation speed, and the sowing amount is strictly controlled to achieve the precision sowing standard required by agriculture.

[0021] In this invention, two small spiral blades 57 are fixedly disposed on the outer surfaces of two large spiral blades 56. The small spiral blades 57 are located inside the diverter 53, which pre-divide and pre-quantitatively comb the collected wheat seeds, breaking up the clumps and stacks of wheat seeds and distributing them evenly to the two large spiral blades 56, adapting to the soft and easily damaged characteristics of the germinated wheat seeds. Two central rods 58 are fixedly disposed on the inner edges of the two small spiral blades 57 and the two large spiral blades 56. The central rods 58 are the central positioning shafts of the spiral assembly, which coaxially fix the small spiral blades 57 and the large spiral blades 56, improve the overall rigidity of the entire spiral structure, prevent the blades from deforming or shifting during operation, and ensure coaxiality and operational stability.

[0022] In this invention, two vertical discs 59 are fixedly sleeved on the outer surfaces of two discharge cylinders 55. The vertical discs 59 are annular connecting discs, which on the one hand realize the rigid connection between the discharge cylinders 55 and the rolling wheels 510, and on the other hand play a limiting role to prevent the rolling wheels 510 from shifting left and right, ensuring stable power transmission. Two rolling wheels 510 are respectively arranged around the outside of the two vertical discs 59. When the equipment is pushed forward in the field, the rolling wheels 510 roll in contact with the ground, and drive the vertical discs 59, discharge cylinders 55 and all internal rotating components to rotate synchronously with the help of the walking resistance. There is no need to add an additional walking motor, realizing the integration of walking and sowing power.

[0023] In this invention, the sowing mechanism further includes: a reinforcing plate 512, which is fixedly disposed on the outer surface of the discharge cylinder 55 and the vertical disk 59; the reinforcing plate 512 is a reinforcing connecting rib, welded or fixed at the joint position of the discharge cylinder 55 and the vertical disk 59, to enhance the connection strength and anti-torsion performance of the two, resist the torsional force generated by field bumps and wheat seed pushing, and avoid problems such as weld cracking, structural loosening, and component falling off during long-term operation; a groove 513, the opening of which is disposed on the outer edge of the small spiral blade 57; the groove 513 is an integrally formed limiting groove, the size of which matches the rubber strip 511, used for precise embedding and positioning of the rubber strip 511, to prevent the rubber strip 511 from falling off or shifting during high-speed rotation and wheat seed friction.

[0024] In this invention, a rubber strip 511 is fixedly disposed in the groove 513 of the small spiral blade 57. The rubber strip 511 is made of flexible and wear-resistant rubber material, which buffers the hard collision and compression between wheat seeds and the small spiral blade 57 during operation, effectively protecting the wheat sprouts from breakage and damage. At the same time, it fills the gaps between components, improves the sealing of the cavity, and reduces the blockage caused by wheat seeds getting stuck in the gaps. The interface 54 is located in the middle of the top of the diverter 53. The interface 54 is a circular connecting opening. The feed mechanism is directly opposite the discharge end of the upper conveying pipe 98, achieving a sealed connection between the feeding mechanism and the diverting cylinder 53, allowing wheat seeds to smoothly enter the interior of the diverting cylinder 53 from the conveying pipe 98, preventing wheat seeds from scattering or being lost; the movable port 514 is located in the middle of the top of the support cylinder 5; the movable port 514 is a long strip-shaped through-hole, reserving space for the assembly and movement of the conveying pipe 98, so that the conveying pipe 98 can pass through the support cylinder 5 and enter the diverting cylinder 53, while avoiding structural interference problems caused by equipment vibration and component rotation.

[0025] In this invention, the feeding mechanism includes: a feeding cylinder 9, which is fixedly mounted on a horizontal frame 3; the feeding cylinder 9 is a bucket-shaped storage cavity that is wider at the top and narrower at the bottom, with a volume that can meet the storage needs of wheat seeds for a single field operation, and the inner wall is smooth and without dead corners to prevent wheat seeds from adhering and accumulating, ensuring that the wheat seeds slide smoothly down by their own weight; and tilting rods 91, one end of multiple tilting rods 91 is fixedly mounted on the inner wall of the feeding cylinder 9; the multiple tilting rods 91 are evenly arranged in an inclined shape, suspending and fixing the servo motor 94 from multiple angles, dispersing the vibration and load generated by the operation of the servo motor 94, reducing the motor vibration amplitude, and improving the overall installation stability.

[0026] In this invention, horizontal rods 92, one end of multiple horizontal rods 92 is fixedly installed on the inner wall of the feed cylinder 9; the horizontal rods 92 are arranged horizontally and are specifically used to fix and support bearing 93, to limit the horizontal movement of the internal transmission rods, and to ensure that the axis of rotation of the transmission components does not deviate; bearing 93, the outer side of bearing 93 is fixedly installed on the other end of multiple horizontal rods 92; bearing 93 is fitted on the outside of the transmission rods, playing a role in rotational support, reducing the rotational friction of the rods, making the power transmission smoother, and extending the service life of the transmission components; servo motor 94, the outer surface of servo motor 94 is fixedly installed on the other end of multiple tilting rods 91; servo motor 94 is a dedicated power source for the feeding mechanism, the speed of which can be precisely controlled, driving the eccentric and spiral components below to rotate, and the feeding speed and feeding amount can be changed by adjusting the motor speed, realizing automated and controllable quantitative feeding.

[0027] In this invention, the feeding mechanism further includes: a vertical rod 95, one end of which is fixedly mounted on the power output end at the bottom of the servo motor 94; the vertical rod 95 is a rigid transmission main rod, directly connected to the output shaft of the servo motor 94, transmitting the rotational power of the motor vertically downward to the eccentric rod 96 and the eccentric spiral plate 97, and is the core connecting component for power transmission; the eccentric rod 96, one end of which is fixedly mounted on the other end of the vertical rod 95; the axis of the eccentric rod 96 is misaligned with the axis of the vertical rod 95 to form an eccentric rotation structure, generating radial disturbance during rotation, which, together with the eccentric spiral plate 97, loosens and separates the wheat seeds stacked in the conveying pipe 98, preventing the wheat seeds from clumping and clogging the pipe.

[0028] In this invention, a spiral blade 97 is fixedly mounted on the outer surface of an eccentric rod 96. The spiral blade 97 rotates eccentrically following the eccentric rod 96, continuously rolling and pushing wheat seeds using the spiral blade. Combined with the eccentric structure, the continuous flow of wheat seeds is divided into equal-distance and equal-quantity wheat seed segments, achieving intermittent uniform feeding and controlling the sowing uniformity from the source. A conveying pipe 98 is integrally formed and fixedly mounted at the bottom of the feed cylinder 9. The conveying pipe 98 is movably inserted through the movable opening 514 of the support cylinder 5. The conveying pipe 98 is a closed vertical conveying pipe that connects the feed cylinder 9 and the diverter cylinder 53, guiding the directional conveying of wheat seeds throughout the process. The inner diameter of the pipe is adapted to the size of the wheat seeds, ensuring smooth passage and preventing large-scale jumping and spillage of wheat seeds.

[0029] In this invention, two support columns 2 are fixedly installed at the bottom of the cart frame 1. When the equipment stops working and is parked in place, the support columns 2 contact the ground to bear the entire weight of the machine, suspending the rolling wheels 510 in the air. This prevents the wheels from deforming due to long-term pressure and from sticking to the wheels with mud from the ground, while ensuring that the equipment is parked stably and does not tip over. A push frame 4 is fixedly installed on the surface of the cart frame 1 and the horizontal frame 3. The push frame 4 is ergonomically designed for the operator to hold and apply pushing force to move the entire machine in the field. It is convenient and labor-saving to operate and suitable for long-term field work. A battery 6 is fixedly installed on the cart frame 1. The battery 6 is a rechargeable DC power supply device and is independently powered by a servo motor 94. The control circuit provides power, freeing the device from the constraints of an external power cord and allowing for unrestricted movement, making it fully adaptable to field operations. A control switch 7 is fixedly installed on the top of the battery 6. This switch is an on / off control element used to manually start and stop the power supply circuit, thereby controlling the start and stop of the servo motor 94. Operators can start and stop the feeding function at any time according to the working conditions. Multiple power transmission lines 8 are electrically connected to the battery 6, control switch 7, and servo motor 94. These power transmission lines 8 are neatly laid out according to the circuit layout, connecting all electrical components to form a complete power supply and control circuit, ensuring stable power transmission. The circuit wiring is simple and not easily damaged by field debris.

[0030] In this invention, the axial directions of the central rod 58, the diverter cylinder 53, and the discharge cylinder 55 are coaxially arranged. This coaxial layout of multiple components ensures that the center of rotation of the entire rotating assembly is unified, effectively reducing radial vibration and sway during high-speed rotation, reducing component wear, and allowing wheat seeds to flow in a straight line within the flow path, significantly reducing the probability of jamming. The ends of the two discharge cylinders 55 are respectively movably fitted onto the two ends of the diverter cylinder 53, and the ends of the two discharge cylinders 55 are respectively movably fitted onto the two ends of the support cylinder 5. The support cylinder 5 is movably fitted onto the periphery of the diverter cylinder 53. A multi-layer nested assembly structure is adopted, with reasonable rotational clearance between each component. The overall layout is compact, with high space utilization, and an independent wheat seed conveying chamber is defined. The operation of each structure does not interfere with each other, and the flow path is clearly divided.

[0031] In this invention, the two ends of the diverting cylinder 53 are respectively movably sleeved around the two small spiral blades 57. The spiral directions of the two small spiral blades 57 are opposite. When the two sets of opposite spiral blades 57 rotate, they form a pushing effect, which pushes the wheat seeds collected in the middle evenly to the left and right ends, realizing equal diversion on both sides and ensuring that the seed discharge volume of the left and right outlets is completely consistent. The two small spiral blades 57 are located directly below the conveying pipe 98, and the other end of the conveying pipe 98 is located directly above the interface 54. The upper and lower parts are vertically aligned, and the wheat seeds fall in a straight line in the vertical direction. The falling trajectory is stable and without deviation, and there will be no problem of wheat seeds falling off or accumulating on one side, which further improves the uniformity of diversion.

[0032] In this invention, the small spiral blade 57 and the large spiral blade 56 on the same central rod 58 have the same spiral direction, and the spiral spacing of the small spiral blade 57 and the large spiral blade 56 are consistent. The conveying rhythm and pushing capacity of the two-stage spiral blades are perfectly matched, and the wheat seed conveying speed is constant. There will be no disconnection, accumulation, or interruption of the conveying process, thus ensuring the precision of precision sowing from a structural perspective. The axial direction of the support cylinder 5, the axial direction of the large spiral blade 56, the axial direction of the small spiral blade 57, and the axial direction of the central rod 58 are coaxially arranged. All rotating components inside the sowing mechanism achieve full coaxial operation, resulting in low rotational resistance, low overall machine vibration, and stable operation over long periods of continuous operation. The axial direction of multiple fixed rods 52 is perpendicular to the axial direction of the diverter cylinder 53. The ring-shaped fixed rods 52 are evenly stressed, providing all-round stable support for the diverter cylinder 53 and preventing displacement or tilting of the diverter cylinder 53 due to impact from wheat seeds or vibration of components.

[0033] In this invention, the other end of the conveying pipe 98 is fixedly set in the middle of the top of the diverter 53. The interior of the conveying pipe 98 and the interior of the diverter 53 are connected through the interface 54. The two are fixedly connected to form a closed conveying channel. The wheat seeds are conveyed in the closed cavity throughout the process, which effectively prevents wind and sand and dust from mixing into the wheat seeds and completely eliminates the loss of wheat seeds during the conveying process. The interface 54 is located directly above the movable port 514. The two discharge cylinders 55 are rotatably sleeved on both ends of the support cylinder 5 through two bearings 51. The interface positions are precisely corresponding and the pipeline is tightly connected to the cavity. The bearings 51 ensure that the discharge cylinders 55 rotate flexibly and smoothly. The dynamic and static parts are reasonably matched, and the overall sealing performance and motion performance are taken into account.

[0034] In this invention, the axial directions of the vertical rod 95, the axial direction of the eccentric rod 96, the axial direction of the eccentric spiral blade 97, and the axial direction of the conveying pipe 98 are kept parallel. The transmission rods are aligned with the direction of the conveying pipe, and the power transmission direction matches the wheat seed conveying direction. This results in low power loss, high transmission efficiency, and timely response to the feeding action. The axial direction of the eccentric rod 96 is biased to one side of the axial direction of the vertical rod 95, and the axial direction of the eccentric spiral blade 97 is biased to one side of the axial direction of the vertical rod 95. The stirring effect generated by the eccentric rotation continuously disperses the wheat seeds that are stuck together and stacked in the conveying pipe 98. This is especially suitable for wheat seeds that are moist and prone to clumping after soaking, thus solving the problem of pipe blockage at its source. The conveying pipe 98 is movably sleeved around the eccentric rod 96 and the eccentric spiral blade 97. The vertical rod 95 is located directly above the two small spiral blades 57. The upper and lower components are arranged in a regular spatial arrangement, with one-to-one vertical correspondence. The wheat seed feeding path is continuous and smooth. The power components and the conveying components are arranged in separate zones without interfering with each other. The overall structure layout is scientific and reasonable.

[0035] In operation, wheat seeds are first poured into the feed cylinder 9, then into the conveying pipe 98. When the eccentric spiral blade 97 is stationary, it prevents the wheat seeds from falling through the conveying pipe 98 and entering the diverter cylinder 53. The servo motor 94 is powered on via the control switch 7. The servo motor 94 drives the vertical rod 95, eccentric rod 96, and eccentric spiral blade 97 to rotate inside the conveying pipe 98. The rotation of the eccentric spiral blade 97 causes the wheat seeds to roll from top to bottom inside the conveying pipe 98, moving them intermittently from top to bottom. The eccentric rod 96 rotates around the axis of the vertical rod 95, with its axis biased to one side of the vertical rod 95's axis. Simultaneously, the eccentric spiral blade 97 rotates around the axis of the vertical rod 95, and the rotation of the eccentric rod 96 and eccentric spiral blade 97 within the conveying pipe 98 continuously squeezes the seeds. Wheat seeds are pressed, and the spiral blades 97 separate the wheat seeds, allowing for equal and spaced delivery of wheat seeds. The wheat seeds are delivered into the distribution cylinder 53 at equal intervals. The wheat seeds enter between the two small spiral blades 57, and then the hand-push frame 4 is pushed by hand, causing the rolling wheel 510 to move on the sowing ground. This causes the discharge cylinder 55, large spiral blade 56, small spiral blade 57, central rod 58, vertical disk 59, and rolling wheel 510 to rotate synchronously. The small spiral blades 57 roll the wheat seeds inside the distribution cylinder 53, and the two small spiral blades 57 divide the wheat seeds and discharge them through both ends of the distribution cylinder 53. The discharge cylinder 55 and the large spiral blade 56 rotate synchronously, allowing the wheat seeds to move quantitatively and at intervals inside the discharge cylinder 55. The wheat seeds are discharged and scattered on the ground through the two discharge cylinders 55, sowing the wheat seeds evenly on the ground. The large spiral blade 56 rolls the wheat seeds and discharges them from the discharge cylinder 55 at equal intervals, allowing for equal and precise sowing.
