Description

Technical Field

[0001] This invention relates to the field of intelligent seeding equipment technology, specifically to an intelligent seeding method and equipment for dryland wheat. Background Technology

[0002] The intelligent dryland wheat sowing equipment is a modern agricultural machine that integrates advanced technologies (such as intelligent control systems, sensors, navigation systems, etc.). It can accurately control parameters such as sowing amount, depth, and row spacing to achieve efficient, uniform, and cost-effective dryland wheat sowing operations. The core function is an intelligent APP or control system: it can automatically calculate the sowing amount through preset parameters (such as sowing amount per acre, row spacing, and plant spacing) to prevent double sowing or missed sowing.

[0003] Traditional intelligent wheat sowing equipment for dryland typically involves the drive unit moving to open furrows, and then a feeding mechanism scatters wheat from the hopper into the furrows. However, this equipment lacks a soil moisture monitoring system, making it difficult to adjust the furrow depth based on soil moisture levels. Since soil moisture cannot be monitored in real time, the furrow depth can only be adjusted before the equipment moves, resulting in uniform sowing depths. If the soil moisture is high, deeper furrows will lead to deeper sowing; conversely, if the moisture is low, shallower furrows will lead to shallower sowing. Neither of these conditions is conducive to wheat germination and growth.

[0004] Currently, intelligent wheat sowing equipment for dryland typically feeds wheat onto a cylindrical feeding tray. The feeding tray has multiple troughs around its circumference to hold wheat. The feeding tray is driven by a drive mechanism to connect the troughs to the feeding pipe, thus completing the feeding process. For example, patent CN222485302U also discloses a precision wheat sowing device for dryland. Although the amount of wheat fed is controlled by the troughs on the cylindrical feeding tray, the distance between the feeding pipe and the feeding tray is small, and the multiple feeding trays are fixed on the rotating shaft and are difficult to disassemble. This makes it inconvenient to control the volume of the troughs to control the amount of wheat fed in a single operation.

[0005] Currently, intelligent seeding equipment has both funnel-shaped and rectangular hoppers. Regardless of the shape, when loading wheat into the hopper, the significant vibration caused by the seeder's movement leads to the wheat inside becoming increasingly compacted, which is not conducive to the wheat being fed out. Summary of the Invention

[0006] To address the problems in the existing technology, this invention provides a method and equipment for intelligent sowing of wheat in dryland areas.

[0007] The technical solution adopted by this invention to solve its technical problem is: an intelligent wheat sowing equipment for dryland, comprising multiple fixed frames, each fixed frame having a storage mechanism installed on it, each storage mechanism having a furrowing and covering mechanism installed on it, a feeding mechanism installed inside each storage mechanism, a drive mechanism connected to the feeding mechanism installed on each fixed frame, and the furrowing and covering mechanism including a mounting frame installed on one side of the storage mechanism, a fixed base fixedly connected to the bottom of the mounting frame, a furrowing plate provided at one end of the fixed base, a trailer frame fixedly connected to each of the multiple mounting frames, and wheels installed on the fixed frames and mounting frames; wherein an intelligent adjustment mechanism is installed between two of the mounting frames; the intelligent adjustment mechanism includes a sliding plate, each of the multiple furrowing plates having a sliding plate fixedly connected to it, a connecting rod fixedly connected between two adjacent sliding plates, and the two middle mounting frames rotating between each other. The system is connected to a rotating shaft, with a gear keyed at the center of the shaft. Two drive plates are symmetrically fixed to the shaft about the gear, and each drive plate has two drive slots symmetrically formed about the shaft. One connecting rod is inserted into the two drive slots on the same side. An inverted L-shaped support frame is fixedly connected to the center of the back side of the trailer frame. A soil moisture detector is slidably connected to the support frame. The bottom height of the soil moisture detector is greater than the bottom height of the trenching plate. Side rods are fixedly connected to both sides of the soil moisture detector, and the two side rods are respectively inserted into the other two drive slots on the other side. A drive component is installed on the support frame, and a rack that meshes with the gear is fixedly connected to the telescopic end of the drive component.

[0008] Specifically, the intelligent adjustment mechanism also includes an inner plate and a second spring. The inner sides of the multiple sliding plates are all fixedly connected with an inner plate of a convex shape, and a second spring is installed between the inner plate and the mounting frame.

[0009] Specifically, the intelligent adjustment mechanism also includes a slide rod and a spring. The soil moisture detector is fixedly connected to the slide rod, which is slidably connected to the support frame. The soil moisture detector and the support frame are clamped together.

[0010] Specifically, the trenching and covering mechanism also includes a covering plate, and a covering plate is rotatably connected to a fixed seat at one end away from the trenching plate. A torsion spring is rotatably connected to the fixed seat. One end of the torsion spring abuts against the fixed seat, and the other end of the torsion spring abuts against the covering plate. The bottom of the trenching plate has an arc-shaped structure, and the covering plate is inclined.

[0011] Specifically, the storage mechanism includes a feeding pipe, and a feeding pipe is fixedly connected to a plurality of fixed frames. The feeding pipe is welded to the mounting frame. A fixed shell with an internal cylindrical structure is fixedly connected to a plurality of feeding pipes. A hopper is fixedly connected to the fixed shell, and a feeding port communicating with the hopper is opened on the fixed shell.

[0012] Specifically, the feeding mechanism includes a rotating drum, and the interior of each of the multiple fixed shells is rotatably connected to a rotating drum, and the side walls of the multiple rotating drums are provided with material grooves at equal intervals.

[0013] Specifically, the feeding mechanism also includes a protective groove. The end of the rotating drum is provided with a protective groove. The side wall of the rotating drum is provided with multiple sets of slots in a circular array. Four of the slots in the circumferential direction are each fitted with an arc-shaped baffle. The four baffles are inserted into the four corresponding slots respectively, and the baffles extend into the inside of the material trough. The ends of the four baffles are fixedly connected with a fixing ring. The width of the fixing ring is greater than the maximum distance between the four slots in the same group. A connecting plate is fixedly connected to the fixing ring. The connecting plate is fixed to the rotating drum by bolts and nuts.

[0014] Specifically, the drive mechanism includes a reinforcing plate, with a reinforcing plate fixedly connected between each of the two adjacent fixed frames.

The end of the connecting rod is rotatably connected to the side wall of the rotating drum. An intermediate plate is fixedly connected to the two middle columns. Belt reels are mounted on the side of the intermediate plate, the output end of the second drive component, and the ends of the four power shafts. Belts are wound around the multiple belt reels.

[0015] Specifically, a stirring mechanism is installed on the rotating drum. The stirring mechanism includes a drive wheel. The side walls of the four rotating drums are all fixedly connected to the drive wheel. The side walls of the four hoppers are all rotatably connected to the stirring shaft. The end of the stirring shaft is keyed to a driven wheel. The drive wheel and the driven wheel are rolled together. Multiple stirring rods are fixedly connected in a spiral shape at equal intervals on the stirring shaft inside the four hoppers.

[0016] A method for operating an intelligent wheat sowing device for dryland includes the following steps:

[0017] S1: The entire equipment is connected to the agricultural machinery via a trailer frame. The agricultural machinery travels on dry land as the power source for the entire equipment. Wheat seeds are added into the hopper. As the entire equipment moves, the ditching plate automatically opens a ditch on the dry land. The second drive unit is activated to make multiple drums rotate simultaneously. When the trough aligns with the discharge port, the wheat seeds fall into the trough. After the seeds align with the discharge pipe, the wheat seeds fall into the ditch. As the equipment moves, the soil covering plate covers the wheat seeds with soil.

[0018] S2: Then, as the drum rotates, it drives the drive wheel to rotate. Since the drive wheel is in contact with the driven wheel at the end of the mixing shaft, the mixing rod stirs the wheat seeds inside the hopper when the drum rotates.

[0019] S3: Finally, before or during sowing, the controller can control the drive component to descend, thereby causing the rack to drive the gear to rotate clockwise. This further enables the drive groove inside the drive plate to drive the two side rods to descend. The soil moisture detector is inserted into the soil to detect moisture. After the controller receives and analyzes the soil moisture signal, it controls the drive component to increase the contraction distance or return to the initial position. When the rack rises, the left side of the drive plate will shift downward, thereby causing the slide plate to descend, making the trenching plate descend a greater distance and the trenching deeper, and vice versa.

[0020] The beneficial effects of this invention are:

[0021] (1) The intelligent wheat sowing equipment for dryland described in this invention has an intelligent adjustment mechanism installed on the trailer frame. When the entire equipment is driven or just enters the dryland, the drive component 1 drives the rack to move downwards. The rack meshes with the gear, thereby driving the rotating shaft to rotate. The right side of the drive plate on the rotating shaft descends, and then drives the sliding plate to move downwards through the drive groove and connecting rod. In turn, the soil moisture detector descends and inserts into the soil. When the entire equipment is in motion, the soil moisture detector can detect the soil moisture as long as it is in contact with the soil. The soil moisture detector transmits the detection data to the controller. After analysis, if the soil moisture is high, the controller can reset the drive component 1 to achieve rack reset, and the gear drives the rack to rotate. Move the two drive plates horizontally. At this time, the soil moisture detector will reset, and the trenching plate will return to its initial height, allowing shallow trenches to be dug. If the soil moisture detected by the moisture detector is low, the controller will control the drive components to retract, and the gear will rotate counterclockwise, further lowering the left side of the drive plate and raising the right side. As the left side of the drive plate lowers, the drive groove on the left side will drive the connecting rod to lower. Multiple connecting rods will simultaneously lower the sliding plate on the side wall of the mounting frame, allowing the trenching plate to penetrate deeper into the soil. The descent depth is determined by the soil moisture detected by the controller, achieving automatic adjustment of the trenching depth to adapt to different soil moisture conditions and provide a suitable growth environment for wheat seeds.

[0022] (2) The intelligent wheat sowing equipment for dryland described in this invention has a feeding mechanism installed inside the storage mechanism. The feeding mechanism is connected to the drive mechanism. If it is necessary to adjust the single feeding amount, pull the transmission rod away from the fixed shell. The transmission rod retracts into the interior of the sliding shell, and the spring retracts until the rotating drum exits from the interior of the fixed shell. The rotating drum can be rotated to face the operator, the nut at the protective groove is removed, and the connecting plate is pulled to further realize the fixing ring. The baffle is taken out and replaced with the corresponding model baffle and inserted into the slot. That is, multiple fixing rings can be prefabricated, and the diameter of the circle formed by the four baffles on the side wall of the fixing ring is different. When different models of baffles are inserted into the corresponding slots, the volume of the material trough can be changed. After replacement, the connecting plate is fixed to the protective groove by the nut and the stud.

[0023] (3) The intelligent wheat sowing equipment for dryland described in this invention has a stirring mechanism installed on the rotating drum. While the rotating drum is rotating, the drive wheel on its side wall drives the driven wheel to rotate, thereby causing the stirring shaft to rotate. The stirring rod on the stirring shaft stirs the wheat seeds in the hopper, preventing the seeds from becoming more and more compacted due to the vibration of the equipment, and ensuring that the seeds are fed smoothly.

Detailed Implementation

[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0039] like Figures 1-12As shown, the intelligent wheat sowing equipment for dryland described in this invention includes multiple fixed frames 1, each fixed frame 1 is equipped with a storage mechanism 2, and each storage mechanism 2 is equipped with a furrowing and covering mechanism 3. A feeding mechanism 6 is installed inside each storage mechanism 2. A drive mechanism 5 connected to the feeding mechanism 6 is installed on each fixed frame 1. The furrowing and covering mechanism 3 includes a mounting frame 301 installed on one side of the storage mechanism 2. A fixed base 302 is fixedly connected to the bottom of the mounting frame 301, and a furrowing plate 303 is provided at one end of the fixed base 302. A trailer frame 9 is fixedly connected to each mounting frame 301, and wheels 8 are installed on the fixed frames 1 and mounting frames 301. An intelligent adjustment mechanism 4 is installed between two mounting frames 301. 4 includes a sliding plate 401, with multiple trenching plates 303 each having a sliding plate 401 fixedly connected to it. A connecting rod 402 is fixedly connected between adjacent sliding plates 401. A rotating shaft 403 is rotatably connected between two intermediate mounting brackets 301. A gear 411 is keyed to the center of the rotating shaft 403. Two drive plates 412 are symmetrically fixedly connected to the rotating shaft 403 about the gear 411. Two drive slots 417 are symmetrically formed on each drive plate 412 about the rotating shaft 403. One connecting rod 402 is inserted into the two drive slots 417 on the same side. An inverted L-shaped support frame 404 is fixedly connected to the center of the back side of the trailer frame 9. A soil moisture detector 413 is slidably connected to the support frame 404. The bottom height of 3 is greater than the bottom height of the trenching plate 303. Side rods 416 are fixedly connected to both sides of the soil moisture detector 413. The two side rods 416 are respectively inserted into the two other drive slots 417 on the other side. A drive component 409 is installed on the support frame 404. A rack 410 meshing with a gear 411 is fixedly connected to the telescopic end of the drive component 409. A controller 408 electrically connected to the drive component 409 and the soil moisture detector 413 is installed on the support frame 404. A battery pack 407 is installed on the support frame 404, and the battery pack 407 is electrically connected to the controller 408. The intelligent adjustment mechanism 4 also includes an inner plate 414 and a second spring 415. A U-shaped structure is fixedly connected to the inner side of each of the multiple sliding plates 401. The inner plate 414 is connected to the mounting frame 301, and a second spring 415 is installed between the inner plate 414 and the mounting frame 301. The intelligent adjustment mechanism 4 also includes a slide rod 405 and a first spring 406. The soil moisture detector 413 is fixedly connected to the slide rod 405, which is slidably connected to the support frame 404. The first spring 406 is clamped between the soil moisture detector 413 and the support frame 404. The trenching and covering mechanism 3 also includes a covering plate 304. The covering plate 304 is rotatably connected to the fixed seat 302 away from the trench plate 303. The fixed seat 302 is rotatably connected to the torsion spring 305. One end of the torsion spring 305 abuts against the fixed seat 302, and the other end of the torsion spring 305 abuts against the covering plate 304. The bottom of the trenching plate 303 has an arc-shaped structure, and the covering plate 304 is inclined.When the entire device is in dry land, part of the furrowing plate 303 is inserted into the soil. After the entire device is taken away, the furrowing plate 303 can open furrows in the dry land. The depth to which the furrowing plate 303 is inserted into the soil is the furrowing depth. When the entire device is horizontal, the soil moisture detector 413 does not contact the soil. During furrowing, the soil moisture can be analyzed in real time for different dry land conditions, thereby automatically adjusting the furrowing depth of the furrowing plate 303. In specific operation: the soil moisture can be detected by the soil moisture detector 413 before or during sowing. First, the controller 408 controls the drive component 409 to extend according to the preset program. 09 is a cylinder. Drive component 409 drives rack 410 downwards, which meshes with gear 411, thus rotating shaft 403. Drive plate 412 on shaft 403 descends to its right side, and then, through drive groove 417 and connecting rod 402, drives slide plate 401 downwards, causing soil moisture detector 413 to descend and insert into the soil. During operation, soil moisture detector 413 only needs to be in contact with the soil to detect soil moisture. The detector 413 transmits the data to controller 408. After analysis, controller 408 determines if the soil moisture is high and resets drive component 409, thus resetting rack 410. 0. Reset, gear 411 drives the two drive plates 412 horizontally, at which point the soil moisture detector 413 resets, and the trenching plate 303 returns to its initial height, allowing shallow trenching. If the soil moisture detected by the soil moisture detector 413 is low, the controller 408 controls the drive component 409 to retract, and gear 411 rotates counterclockwise, further lowering the left side of the drive plate 412 and raising the right side. As the left side of the drive plate 412 lowers, the drive groove 417 on the left side drives the connecting rod 402 to lower. Multiple connecting rods 402 simultaneously lower the sliding plate 401 on the side wall of the mounting frame 301, and the trenching plate 303 will insert into the soil. Deeper into the furrow, the descent depth is determined by the soil moisture detected by the controller 408, enabling automatic adjustment of the furrowing depth to adapt to different soil moisture conditions and provide a suitable growing environment for wheat seeds. Simultaneously, the soil moisture detector 413, under the action of the slide bar 405 and spring 406, can slide stably on the support frame 404, ensuring the accuracy of the detection data. Spring 415 between the inner plate 414 on the inner side of the slide plate 401 and the mounting frame 301 provides cushioning and stabilization, making the adjustment of the furrowing plate 303 smoother. After sowing, the furrowing plate 303 can be adjusted to its initial position via the controller 408.

[0040] Specifically, the storage mechanism 2 includes a feeding pipe 201, with feeding pipes 201 fixedly connected to multiple fixed frames 1. The feeding pipes 201 are welded to the mounting frame 301. Each feeding pipe 201 has a fixed shell 202 with an internal cylindrical structure, and a hopper 203 is fixedly connected to the fixed shell 202. The fixed shell 202 has a feeding port 204 communicating with the hopper 203. The feeding mechanism 6 includes a rotating drum 601, with rotating drums 601 rotatably connected inside the multiple fixed shells 202. The side walls of the multiple rotating drums 601 are... The feeding mechanism 6 also includes a protective groove 603, with a protective groove 603 at the end of the rotating drum 601. The sidewall of the rotating drum 601 has multiple sets of slots 607 arranged in a circular array. Four of the slots 607 in the circumferential direction are fitted with arc-shaped baffles 606. The four baffles 606 are inserted into the four corresponding slots 607, extending into the interior of the feeding groove 602. The ends of the four baffles 606 are fixedly connected with fixing rings 604, the width of which is greater than that of the same set of slots. The maximum distance between the four slots 607; a connecting plate 605 is fixedly connected to the fixing ring 604; the connecting plate 605 is fixed to the rotating cylinder 601 by bolts and nuts; the drive mechanism 5 includes a reinforcing plate 504; a reinforcing plate 504 is fixedly connected between each of two adjacent fixing frames 1; a drive component 506 is installed on the middle reinforcing plate 504; a column 501 is installed on each of the four fixing frames 1; a power shaft 510 is rotatably connected to each of the four columns 501; and a sliding housing 502 is fixedly connected to the end of each of the four power shafts 510. Inside the sliding housing 502, there is a hexagonal prism-shaped transmission rod 503 that is slidably connected. A spring 511 is clamped between the sliding housing 502 and the transmission rod 503. The ends of the four transmission rods 503 are rotatably connected to the connecting rods 505. The ends of the connecting rods 505 are rotatably connected to the side wall of the rotating drum 601. An intermediate plate 508 is fixedly connected to the two middle columns 501. The sides of the intermediate plate 508, the output end of the drive component 506, and the ends of the four power shafts 510 are all equipped with pulleys 509. Belts 507 are wound around the multiple pulleys 509.The entire device is connected to the farming device via the connecting seat on the trailer frame 9. The farming device serves as the power source, driving the entire device into the dry land. An appropriate amount of wheat seeds is loaded into each hopper 203. During loading, care should be taken not to overfill to avoid seed overflow due to vibration during subsequent sowing. As the farming device moves the entire device, the furrowing plate 303 contacts the soil, creating sowing furrows. The depth to which the furrowing plate 303 is inserted into the soil is the sowing depth. During furrowing, the second drive component 506 is activated. The second drive component 506 is a servo motor that drives the four power shafts 510 to rotate via the pulley 509 and belt 507. The drive shaft 510 drives the sliding housing 502 to rotate, and the transmission rod 503 inside the sliding housing 502 rotates accordingly. Since the transmission rod 503 has a hexagonal prism structure, it will not slip. It further drives the rotating drum 601 to rotate through the connecting rod 505. During the rotation of the rotating drum 601, the material trough 602 on its side wall aligns with the discharge port 204 on the fixed housing 202 in sequence. Wheat seeds enter the material trough 602 from the hopper 203 through the discharge port 204. After the material trough 602 with wheat seeds aligns with the discharge pipe 201, the wheat seeds fall into the interior of the discharge pipe 201, and then fall into the groove opened by the ditching plate 303 through the discharge pipe 201. After the wheat seeds fall into the groove, The soil covering plate 304, under the action of the torsion spring 305, covers the seeds with soil, completing the sowing and covering operations. The soil covering plate 304 is tilted to better cover the seeds with soil and ensure sowing quality. The disc 509 on the middle plate 508 can increase the friction of the other discs 509, preventing the drive shaft 510 from slipping and causing the rotating drum 601 to be unable to rotate, thus affecting the feeding. If it is necessary to adjust the single feeding amount, pull the transmission rod 503 away from the fixed shell 202. The transmission rod 503 retracts into the sliding shell 502, and the spring 511 retracts until the rotating drum 601 exits from the inside of the fixed shell 202. The rotating drum 601 can then be rotated to face the operator. The author removes the nut at the protective groove 603, pulls the connecting plate 605, and further removes the retaining ring 604 and the baffle 606. A corresponding model baffle 606 is then inserted into the slot 607. Multiple retaining rings 604 can be pre-fabricated, and the diameter of the circle formed by the four baffles 606 on the side wall of the retaining ring 604 is different. When different models of baffles 606 are inserted into the corresponding slots 607, the volume of the material groove 602 can be changed. After replacement, the connecting plate 605 is fixed to the protective groove 603 using a nut and studs. In short, the larger the diameter of the circle formed by the multiple baffles 606, the smaller the material groove 602, and vice versa.

[0041] Specifically, a stirring mechanism 7 is installed on the rotating drum 601. The stirring mechanism 7 includes a drive wheel 701. The drive wheel 701 is fixedly connected to the side wall of each of the four rotating drums 601. The stirring shaft 704 is rotatably connected to the side wall of each of the four hoppers 203. The end of each stirring shaft 704 is keyed to a driven wheel 702. The drive wheel 701 and the driven wheel 702 are rolled together. Multiple stirring rods 703 are fixedly connected in a spiral shape at equal intervals on the stirring shaft 704 inside each of the four hoppers 203. While the rotating drum 601 rotates, the drive wheel 701 on its side wall drives the driven wheel 702 to rotate, which in turn causes the stirring shaft 704 to rotate. The stirring rods 703 on the stirring shaft 704 stir the wheat seeds in the hopper 203 to prevent the seeds from becoming more compacted due to the vibration of the equipment, and to ensure that the seeds are fed smoothly.

[0042] A method for operating an intelligent wheat sowing device for dryland includes the following steps:

[0043] S1: The entire equipment is connected to the agricultural machinery via the trailer frame 9. The agricultural machinery travels on dry land as the power source for the entire equipment. Wheat seeds are added into the hopper 203. As the entire equipment moves, the ditching plate 303 automatically digs in the dry land. The drive unit 506 is activated to make multiple rotating drums 601 rotate simultaneously. When the trough 602 corresponds to the discharge port 204, the wheat seeds fall into the trough 602. After the seeds correspond to the discharge pipe 201, the wheat seeds fall into the ditch. As the equipment moves, the soil covering plate 304 covers the wheat seeds with soil.

[0044] S2: Then, as the rotating drum 601 rotates, the rotating drum 601 will drive the drive wheel 701 to rotate. Since the drive wheel 701 is in contact with the driven wheel 702 at the end of the stirring shaft 704, the stirring rod 703 stirs the wheat seeds inside the hopper 203 when the rotating drum 601 rotates.

[0045] S3: Finally, before or during sowing, the controller 408 can control the drive component 409 to descend, thereby causing the rack 410 to drive the gear 411 to rotate clockwise. This further enables the drive groove 417 inside the drive plate 412 to drive the two side rods 416 to descend. The soil moisture detector 413 is inserted into the soil for detection. After receiving and analyzing the soil moisture signal, the controller 408 controls the drive component 409 to increase the contraction distance or return to the initial position. When the rack 410 rises, the left side of the drive plate 412 will shift downward, thereby causing the slide plate 401 to descend, making the trenching plate 303 descend a greater distance and the trenching deeper, and vice versa.

[0046] In use, the entire device is first connected to the farming device via the connecting seat on the trailer frame 9. The farming device serves as the power source, driving the entire device into the dry land. An appropriate amount of wheat seeds is loaded into each hopper 203. During loading, care should be taken not to overfill to avoid seed overflow due to vibration during subsequent sowing. As the farming device moves the entire device, the furrowing plate 303 contacts the soil, creating sowing furrows. The depth to which the furrowing plate 303 is inserted into the soil is the sowing depth. During furrowing, the second drive component 506 is activated. The second drive component 506 is a servo motor, which drives the four... The rotation of the drive shaft 510 drives the sliding housing 502 to rotate, and the transmission rod 503 inside the sliding housing 502 rotates accordingly. Since the transmission rod 503 has a hexagonal prism structure, it will not slip. It further drives the rotating drum 601 to rotate through the connecting rod 505. During the rotation of the rotating drum 601, the material trough 602 on its side wall aligns with the discharge port 204 on the fixed housing 202 in sequence. Wheat seeds enter the material trough 602 from the hopper 203 through the discharge port 204. After the material trough 602 with wheat seeds aligns with the discharge pipe 201, the wheat seeds fall into the interior of the discharge pipe 201, and then fall into the groove opened by the ditching plate 303 through the discharge pipe 201. After falling into the trench, the soil covering plate 304, under the action of the torsion spring 305, covers the seeds with soil, completing the sowing and covering operations. The soil covering plate 304 is set at an angle, which helps to better cover the seeds with soil and ensure sowing quality. The disc 509 on the middle plate 508 can increase the friction of the other discs 509, preventing the drive shaft 510 from slipping and causing the rotating drum 601 to be unable to rotate, thus affecting the feeding. If it is necessary to adjust the single feeding amount, pull the transmission rod 503 away from the fixed shell 202. The transmission rod 503 retracts into the sliding shell 502, and the spring 511 retracts until the rotating drum 601 is withdrawn from the inside of the fixed shell 202, allowing the rotating surface of the rotating drum 601 to be rotated. For the operator, remove the nut at the protective groove 603, pull the connecting plate 605, and further remove the baffle 606 from the fixing ring 604. Replace it with the corresponding model baffle 606 and insert it into the slot 607. That is, multiple fixing rings 604 can be prefabricated, and the diameter of the circle formed by the four baffles 606 on the side wall of the fixing ring 604 is different. When different models of baffles 606 are inserted into the corresponding slots 607, the volume of the material groove 602 can be changed. After replacement, fix the connecting plate 605 to the protective groove 603 with the nut and stud. In short, the larger the diameter of the circle formed by multiple baffles 606, the smaller the material groove 602, and vice versa.

[0047] Then, as the drum 601 rotates, the drive wheel 701 on its side wall drives the driven wheel 702 to rotate, which in turn causes the stirring shaft 704 to rotate. The stirring rod 703 on the stirring shaft 704 stirs the wheat seeds in the hopper 203 to prevent the seeds from becoming more compacted due to the vibration of the equipment, and to ensure that the seeds are fed out smoothly.

[0048] Finally, when the entire device is in dry land, part of the furrowing plate 303 is inserted into the soil. After the entire device is taken away, the furrowing plate 303 can open furrows in the dry land. The depth to which the furrowing plate 303 is inserted into the soil is the furrowing depth. When the entire device is horizontal, the soil moisture detector 413 does not contact the soil. During furrowing, the soil moisture can be analyzed in real time for different dry lands, thereby automatically adjusting the furrowing depth of the furrowing plate 303. In specific operation: the soil moisture can be detected by the soil moisture detector 413 before or during sowing. First, the controller 408 controls the drive component 409 to extend according to the preset program. 409 is a cylinder. Driven by 409, the rack 410 moves downwards, meshing with gear 411, which in turn rotates the shaft 403. The drive plate 412 on the shaft 403 descends to its right side, and then, through the drive groove 417 and connecting rod 402, drives the slide plate 401 downwards, causing the soil moisture detector 413 to descend and insert into the soil. During operation, the soil moisture detector 413 only needs to be in contact with the soil to detect soil moisture. The detector 413 transmits the data to the controller 408. After analysis, if the controller 408 determines that the soil moisture is high, it resets the rack via drive 409. 410 resets, gear 411 drives the two drive plates 412 horizontally, at which point the soil moisture detector 413 resets, and the trenching plate 303 returns to its initial height, allowing shallow trenching to begin. If the soil moisture detected by the soil moisture detector 413 is low, the controller 408 controls the drive component 409 to retract, and gear 411 rotates counterclockwise, further lowering the left side of the drive plate 412 and raising the right side. As the left side of the drive plate 412 lowers, the drive groove 417 on the left side drives the connecting rod 402 to lower. Multiple connecting rods 402 simultaneously lower the sliding plate 401 on the side wall of the mounting frame 301, causing the trenching plate 303 to insert into the mud. The descent depth is determined by the soil moisture detected by the controller 408, enabling automatic adjustment of the furrowing depth to adapt to different soil moisture conditions and provide a suitable growth environment for wheat seeds. At the same time, the soil moisture detector 413 can slide stably on the support frame 404 under the action of the slide bar 405 and the first spring 406, ensuring the accuracy of the detection data. The second spring 415 between the inner plate 414 on the inner side of the slide plate 401 and the mounting frame 301 plays a buffering and stabilizing role, making the adjustment of the furrowing plate 303 more stable. After sowing, the furrowing plate 303 can be adjusted to the initial position by the controller 408.
