[0048] like Figure 1-19 As shown, in one embodiment of the present invention, a bean sowing and fertilizing integrated machine is provided, including a vehicle body 100, multiple furrowing plows 200, a spacing adjustment mechanism 300, a lifting mechanism 400, multiple sowing mechanisms 500, multiple fertilizing mechanisms 600, and a synchronization mechanism 700.

[0049] The vehicle body 100 is equipped with a suspension system. When the machine traverses terrain with significant undulations, the suspension system can adjust the angle between the suspensions of the two wheels to ensure that the wheels maintain contact with the ground even on uneven surfaces, thereby providing continuous power transmission. When traversing bumpy roads, shock-absorbing springs absorb the vibrations generated by the bumps to prevent damage to the machine from vibration, while also ensuring the stability of the sowing operation. The vehicle body 100 and the suspension system are existing technologies and will not be described in detail in this embodiment.

[0050] Three furrowing plows 200 are installed on the spacing adjustment mechanism 300. The three furrowing plows 200 are arranged at intervals along the width direction of the vehicle body 100. The furrowing plows 200 are used to dig furrows along the traveling direction of the vehicle body 100 and cover the furrows with soil. The spacing adjustment mechanism 300 is used to adjust the spacing between the two furrowing plows 200 on the outer side and the furrowing plow 200 in the middle, thereby realizing the adjustment of the furrow spacing, that is, the adjustment of the sowing spacing.

[0051] The lifting mechanism 400 drives the spacing adjustment mechanism 300 and the furrowing plow 200 to lift and lower, thereby adjusting the furrow depth. Three sowing mechanisms 500 are mounted on the vehicle body 100, each corresponding to one furrowing plow 200. The sowing mechanism 500 stores seeds and discharges them into the furrows created by the corresponding furrowing plow 200. Three fertilizing mechanisms 600 are mounted on the vehicle body 100, each corresponding to one sowing mechanism 500. The fertilizing mechanism 600 stores fertilizer and discharges it into the furrows created by the corresponding furrowing plow 200. A synchronization mechanism 700 drives the sowing mechanism 500 and the fertilizing mechanism 600 to discharge fertilizer synchronously, achieving synchronized sowing and fertilizing actions.

[0052] This embodiment discloses a bean planting and fertilizing integrated machine. Through the coordinated design of a spacing adjustment mechanism 300, a lifting mechanism 400, a planting mechanism 500, a fertilizing mechanism 600, and a synchronization mechanism 700, it can adjust the spacing and height of the furrowing plow 200 according to actual needs, thereby achieving bean planting operations at different depths and spacings. Simultaneously, the planting mechanism 500 and the fertilizing mechanism 600 can simultaneously discharge seeds and fertilizer into the opened furrows, and the furrowing plow 200 can cover the furrows with soil to ensure normal seed growth. Compared with existing small-scale planting machinery, this bean planting and fertilizing integrated machine can adapt to the complex terrain of hilly farmland, has diversified functions such as adjusting planting spacing and planting depth, solves the problem of mechanized planting in hilly areas, improves planting efficiency and utilization rate of hilly farmland, and reduces manual labor.

[0053] In one embodiment, the sowing mechanism 500 includes a seed box 501, a seed metering wheel, and a first feed pipe (not shown in the figures). The seed box 501 has a first discharge hole 502 at its bottom and a clearance hole 503 on its side wall. The seed metering wheel is disposed inside the seed box 501, forming a first channel 504 between the seed metering wheel and the inner wall of the seed box 501. The first channel 504 communicates with the first discharge hole 502. One end of the first feed pipe is connected to the first discharge hole 502, and the other end of the first feed pipe extends to the rear side of the furrowing plow 200.

[0054] The seed-rearing wheel includes a first wheel body 505, a second wheel body 507, and a drive mechanism. The side of the first wheel body 505 facing away from the clearance hole 503 abuts against the inner wall of the seed box 501. The outer wall of the first wheel body 505 is provided with multiple first receiving grooves 506. The second wheel body 507 is engaged with the first wheel body 505 without relative rotation. The second wheel body 507 is movably fitted within the clearance hole 503. The outer wall of the second wheel body 507 is provided with multiple second receiving grooves 508. The second receiving grooves 508 and the first receiving grooves 506 together form a seed trough 509 of variable size. The drive mechanism has a first rotation direction and a second rotation direction with opposite rotation directions.

[0055] During sowing, when the drive mechanism rotates in the first direction, it drives the first wheel 505 and the second wheel 507 to rotate in one direction, so as to discharge the seeds in the seed trough 509 to the first channel 504, and finally discharge them from the discharge hole and the first material pipe, thereby discharging the seeds into the furrow opened by the furrowing plow 200. Then, the furrowing plow 200 covers the furrow with soil, thereby burying the seeds in the soil.

[0056] When the size of the seed groove 509 needs to be adjusted, the drive mechanism rotates along the second rotation direction. The drive mechanism rotates relative to the first wheel body 505, and the drive mechanism drives the second wheel body 507 to move relative to the first wheel body 505 to adjust the size of the seed groove 509.

[0057] The sowing mechanism 500 has a seed dispensing function and a seed trough 509 size adjustment function. By switching the rotation direction of the drive mechanism, when the drive mechanism rotates the first wheel 505 and the second wheel 507 along the first rotation direction, the seeds in the seed trough 509 can be discharged through the first channel 504 to the first discharge hole 502, thereby realizing the seed dispensing function. When the drive mechanism rotates along the second rotation direction, the drive mechanism can drive the second wheel 507 to move closer to or further away from the first wheel 505. In this way, the distance between the second receiving trough 508 and the first receiving trough 506 can be changed, thereby realizing the size adjustment of the seed trough 509. This allows for the dispensing operation of different types and quantities of beans, meeting different usage needs and improving the applicability of the whole machine.

[0058] Furthermore, the drive mechanism includes a first rotating shaft 510, a unidirectional rotation drive assembly, a first end face cam 511, a second end face cam 512, and a first elastic element 513. The first rotating shaft 510 is coaxially mounted on the first wheel body 505 and the second wheel body 507, and the first rotating shaft 510 has no contact with the first wheel body 505 and the second wheel body 507. The first rotating shaft 510 can rotate in either a first rotation direction or a second rotation direction.

[0059] A unidirectional rotation drive assembly is disposed within the first wheel body 505 and connected to the first rotating shaft 510. The unidirectional rotation drive assembly drives the first wheel body 505 to perform a unidirectional rotational action. A first end face cam 511 is coaxially disposed within the first wheel body 505, and the first end face cam 511 is located on the end face of the unidirectional rotation drive assembly facing the second wheel body 507. A second end face cam 512 is coaxially disposed within the second wheel body 507, and the second end face cam 512 can cooperate with the first end face cam 511. A first elastic member 513 applies a spring force to the second wheel body 507, causing the second wheel body 507 to tend to move towards the first wheel body 505.

[0060] The end face of the first end face cam 511 is provided with two first protrusions, which are symmetrically arranged along the axis of the first end face cam 511. The end face of the second end face cam 512 is provided with two second protrusions, which are symmetrically arranged along the axis of the second end face cam 512, and the second protrusions can abut against the first protrusions.

[0061] When the first rotating shaft 510 rotates along the first rotation direction, the first rotating shaft 510 drives the unidirectional rotation drive component to cooperate with the first wheel body 505, thereby driving the first wheel body 505 and the second wheel body 507 to rotate along the first rotation direction as well. Since the first end face cam 511 will rotate synchronously with the first rotating shaft 510 along the first rotation direction, and the second end face cam 512 will also rotate synchronously with the second wheel body 507 along the first rotation direction, the first end face cam 511 will not cooperate with the second end face cam 512. In this way, the seeding mechanism 500 can be switched to the seeding function.

[0062] When the first rotating shaft 510 rotates along the second rotation direction, the unidirectional rotation drive assembly will not cooperate with the first wheel body 505, thus failing to drive the first wheel body 505 and the second wheel body 507 to rotate. At this time, the first wheel body 505 and the second wheel body 507 will not rotate. Since the first end face cam 511 rotates synchronously with the first rotating shaft 510 along the first rotation direction, and the second end face cam 512 is in a stationary state, the first end face cam 511 will intermittently push against the second end face cam 512. During the pushing process, the second wheel body 507 will move away from the first wheel body 505, thereby enlarging the seed groove 509.

[0063] When the first protrusion of the first end face cam 511 abuts against the second protrusion of the second end face cam 512, the size of the seed groove 509 is at its maximum. As the second wheel body 507 moves away from the first wheel body 505, the first elastic member 513 continuously applies elastic force to the second wheel body 507. As the first protrusion gradually moves to a position between the two second protrusions, the first elastic member 513 gradually moves against the second wheel body 507 towards the first wheel body 505, thereby gradually reducing the size of the seed groove 509.

[0064] Furthermore, the first wheel body 505 is provided with a first groove 514, and the second wheel body 507 is provided with a second groove 515 on the side facing the first groove 514. The unidirectional rotation drive assembly includes a ratchet 516, a pawl 517, and a plurality of second elastic elements. The ratchet 516 is fixedly sleeved outside the first rotating shaft 510 and located in the first groove 514, and the ratchet 516 is connected to the first end face cam 511. The pawl 517 is rotatably disposed in the first groove 514, and the pawl 517 can engage with the ratchet 516. The plurality of pawls 517 are arranged in a circular array along the axis of the first wheel body 505. Each second elastic element corresponds to one pawl 517, and the second elastic element is used to apply a spring force to the pawl 517 to prevent it from disengaging from the ratchet 516.

[0065] When the first rotating shaft 510 rotates in the first direction of rotation, the first rotating shaft 510 drives the ratchet 516 to rotate synchronously. When the ratchet teeth of the ratchet 516 mesh with the pawl 517, the ratchet 516 will drive the first wheel body 505 to rotate in the first direction of rotation, thereby causing the first wheel body 505 to drive the second wheel body 507 to rotate synchronously. In this way, the seeding mechanism 500 can be switched to the seeding function.

[0066] When the first shaft 510 rotates in the second direction of rotation, it drives the ratchet 516 to rotate synchronously. The ratchet teeth of the ratchet 516 cannot engage with the pawl 517, therefore the ratchet 516 cannot drive the first wheel body 505 to rotate, and consequently, the second wheel body 507 will not rotate. Since the first end face cam 511 rotates synchronously in the first direction of rotation along with the first shaft 510 and the ratchet 516, and the second end face cam 512 is stationary, the first end face cam 511 will intermittently push against the second end face cam 512. During this pushing process, the second wheel body 507 will move away from the first wheel body 505, thereby enlarging the seed groove 509.

[0067] The seeding mechanism 500 has an ingenious overall structural design, which facilitates the switching between the seed metering function and the size adjustment function of the seed trough 509, meeting the usage needs in different scenarios.

[0068] In one embodiment, a limiting sleeve 518 is fixedly sleeved on the first rotating shaft 510. A first elastic element 513, selected as a spring, is sleeved outside the first rotating shaft 510. One end of the first elastic element 513 abuts against the limiting sleeve 518, and the other end extends into the clearance hole 503 and abuts against the end face of the second wheel body 507. An annular retaining ring 519 extends from the end face of the second wheel body 507 away from the first wheel body 505. The outer diameter of the annular retaining ring 519 is the same as the outer diameter of the second wheel body 507, and the outer sidewall of the annular retaining ring 519 mates with the inner sidewall of the clearance hole 503. By designing the annular retaining ring 519 on the second wheel body 507, the second wheel body 507 can always cover the clearance hole 503 during movement, preventing seeds in the seed box 501 from leaking out of the clearance hole 503.

[0069] In one embodiment, the first wheel body 505 extends towards the end face of the second wheel body 507 to form multiple extension blocks 520. A first support portion 521 is provided between two adjacent extension blocks 520, and a first receiving groove 506 is disposed within the first support portion 521. The end face of the second wheel body 507 facing the first wheel body 505 has a slot 522 with an annular structure. The extension blocks 520 can extend into the slot 522. The side wall of the second wheel body 507 has multiple notches communicating with the slot 522. A second support portion 523 is provided within the notches, and a second receiving groove 508 is disposed within the second support portion 523. With the cooperation of the extension blocks 520 and the slot 522, as the second wheel body 507 moves away from the first wheel body 505, the extension blocks 520 can block the gap between the first wheel body 505 and the second wheel body 507, thereby preventing seeds from falling into the inner cavities of the first wheel body 505 and the second wheel body 507.

[0070] Furthermore, a groove is formed on the side of the first support portion 521 opposite to the axis of the first wheel body 505. The groove has a first inclined surface 524, and the end of the first inclined surface 524 near the second wheel body 507 is inclined towards the axis of the first wheel body 505. The second support portion 523 cooperates with the groove, and a second inclined surface is provided on the side of the second support portion 523 facing the slot 522. The second inclined surface cooperates with the first inclined surface 524. An elastic baffle 525 is provided on the second inclined surface, and the elastic baffle 525 abuts against the first inclined surface 524. By designing the first inclined surface 524 and the second inclined surface to cooperate, the depth of the seed groove 509 can be increased during the adjustment of the size of the seed groove 509, thereby accommodating different types of beans. At the same time, the elastic baffle 525 can prevent small impurities in the seed groove 509 from falling into the inner cavity of the first wheel body 505 and the second wheel body 507.

[0071] In one embodiment, a baffle brush 526 is provided in the first channel 504, and the baffle brush 526 contacts the outer wall of the seed metering wheel. The seed box 501 is provided with a hopper and a baffle block 527, with the hopper located above the seed metering wheel. A second channel 528 is formed between the seed metering wheel and the inner wall of the seed box 501, and the second channel 528 and the first channel 504 are respectively arranged on both sides of the seed metering wheel. The baffle block 527 contacts the outer wall of the seed metering wheel and is used to prevent seeds entering the hopper from entering the second channel 528. During the rotation of the seed metering wheel in the first direction of rotation, the baffle brush 526 will block the seeds, allowing only the seeds in the seed trough 509 to enter the first channel 504, thereby evenly conveying the seeds to the first discharge hole 502.

[0072] In one embodiment, the spacing adjustment mechanism 300 includes a first guide component 301, a second guide component 302, and a spacing adjustment drive component. Both the first guide component 301 and the second guide component 302 are mounted on the vehicle body 100, with the first guide component 301 positioned above the second guide component 302. Both the first guide component 301 and the second guide component 302 are used for guiding along the width direction of the vehicle body 100. Three trenching plows 200 are arranged at intervals along the width direction of the vehicle body 100. The trenching plow 200 located in the middle position is fixed to the first guide component 301 and the second guide component 302, while the other two trenching plows 200 are slidably engaged with the first guide component 301 and the second guide component 302, respectively. The spacing adjustment drive component drives the two outer trenching plows 200 to move synchronously closer or further apart.

[0073] For ease of distinction, the middle furrowing plow 200 is designated as furrowing plow 200a, and the two outer furrowing plows 200 are designated as furrowing plow 200b and furrowing plow 200c, respectively. Further, the spacing adjustment drive assembly includes a first motor 303, a first connecting rod 304, a second connecting rod 305, a third connecting rod 306, and two fourth connecting rods 307. The first motor 303 is fixed to furrowing plow 200b, and the first connecting rod 304 is connected to the first rotating shaft 510 of the first motor 303. One end of the second connecting rod 305 is hinged to the first connecting rod 304, and the other end is hinged to furrowing plow 200a. The third connecting rod 306 is rotatably mounted on top of furrowing plow 200a. Each fourth link 307 corresponds to a furrowing plow 200b and a furrowing plow 200c. One end of the fourth link 307 is hinged to the third link 306, and the other end of the fourth link 307 is hinged to the top of the corresponding furrowing plow 200b or c.

[0074] When the first motor 303 drives the first connecting rod 304 to rotate, since the furrowing plow 200a is stationary, the first connecting rod 304, as it rotates with the shaft of the first motor 303, will cause the furrowing plow 200b to move (closer or farther away) relative to the furrowing plow 200a along the first guide assembly 301 and the second guide assembly 302. Simultaneously, the fourth connecting rod 307 connected to the furrowing plow 200b will cooperate with the third connecting rod 306, causing the third connecting rod 306 to drive the other fourth connecting rod 307. This will cause the furrowing plows 200b and 200c to move synchronously toward or away from the furrowing plow 200a. Thus, the distance between the furrowing plows 200b and 200a, and between the furrowing plows 200c and 200a, can be adjusted, thereby adjusting the sowing spacing.

[0075] In one embodiment, the lifting mechanism 400 includes two third guide components 401, two first synchronous belt drive components 402, and a second motor 403. The two third guide components 401 guide the vehicle body 100 along its height, and a first guide component 301 is mounted on each of the two third guide components 401. Each first synchronous belt drive component 402 corresponds to one third guide component 401 and is connected to the first guide component 301. The second motor 403 is mounted on the vehicle body 100 and has a second rotating shaft 404, which is connected to the two first synchronous belt drive components 402. When the second motor 403 drives a second rotation, the second rotating shaft 404 drives the two first synchronous belt drive components 402, causing the synchronous belt to move. This causes the synchronous belt to drive the first guide components 301 and the three furrowing plows 200 to move up and down as a whole, thereby adjusting the sowing depth.

[0076] In one embodiment, the furrowing plow 200 includes a first rod 201, a second rod 202, a plow head 203, a covering fork 204, and a third elastic member. The first rod 201 is connected to a first guide assembly 301 and a second guide assembly 302, respectively. The top end of the second rod 202 is hinged to the bottom end of the first rod 201. The plow head 203 and the covering fork 204 are respectively located on both sides of the second rod 202. The third elastic member applies a spring force to the second rod 202 so that the second rod 202 rotates towards the covering fork 204 and then returns to its original position. The covering fork 204 is used to cover the soil on both sides of the furrow with soil after the plow head 203 has created the furrow, thereby covering the seeds and fertilizer.

[0077] During the trenching process, if the plowshare 203 encounters a hard object, the second rod 202 will flip relative to the first rod 201 to avoid the hard object. After passing the hard object, the second rod 202 will return to a vertical state under the action of the third elastic element.

[0078] In one embodiment, the fertilization mechanism 600 includes a feed box 601, a second feed pipe (not shown in the figures), a discharge wheel 602, and a third rotating shaft 603. The feed box 601 is mounted on the vehicle body 100, and a second discharge hole is provided at the bottom of the feed box 601. One end of the second feed pipe is connected to the second discharge hole, and the other end of the second feed pipe extends to the rear side of the plow head 203. That is, the discharge ports of both the first and second feed pipes are located inside the covering fork 204. In this way, after the seeds are discharged from the first feed pipe and the fertilizer is discharged from the second feed pipe, they will fall into the furrow opened by the plow head 203, and the covering fork 204 will then cover the furrow with soil from both sides, thereby covering the seeds and fertilizer.

[0079] The feeding wheel 602 is rotatably mounted inside the material box 601. Multiple material troughs 604 are provided on the outer wall of the feeding wheel 602. A third rotating shaft 603 is mounted on the vehicle body 100 and connected to each feeding wheel 602. The synchronization mechanism 700 includes a second synchronous belt drive assembly, which drives and connects the third rotating shaft 603 and the first rotating shaft 510 respectively. Under the action of the synchronization mechanism 700, the synchronous rotation of the seed feeding wheel and the feeding wheel 602 can be achieved, thereby realizing the synchronous action of sowing and fertilizing.
