[0037] like Figure 1 As shown in the figure, this application embodiment provides an automatic seeding device, which includes a housing 101, a seeding mechanism 200, and a feeding mechanism 400. Specifically, the automatic seeding device is used for peanut planting.

[0038] In this process, seeds enter the automatic seeding device through the feeding mechanism 400, and the seeds of approximately the same quantity are transported in batches to the seeding mechanism 200. The seeding mechanism 200 then sequentially introduces each batch of seeds into each planting hole to ensure that the number of seeds in each planting hole is approximately the same, thereby improving the accuracy of the seeding operation.

[0039] In some examples, the housing 101 is hollow, and both the seeding mechanism 200 and the feeding mechanism 400 are located inside the housing 101. On the one hand, the housing 101 can protect the internal structure; on the other hand, the housing 101 can also provide a stable frame for the entire device, improving the overall structural strength of the device.

[0040] The front top of the housing 101 has a downward-sloping ramp, which allows the user to observe the road conditions ahead when operating the device for automatic seeding. This helps in real-time adjustment of the device's direction of travel, enabling the device to avoid obstacles or unsuitable planting areas in a timely manner. In addition, the housing 101 also prevents external debris from entering the device and affecting the normal operation of the various mechanisms inside the housing 101.

[0041] Furthermore, a bracket 102 is fixedly connected to the surface of the housing 101; specifically, the bracket 102 is located on the outer side of the housing 101. The bracket 102 supports the device and provides a stable mounting position for each component. It is understood that the bracket 102 has high strength and stability, enabling the device to withstand various forces during the planting process. During device movement, the bracket 102 effectively disperses the reaction force from the ground, ensuring the smooth operation of the device.

[0042] Meanwhile, a handle 103 is provided at the rear end of the automatic seeding device. The handle 103 is connected to the housing 101, or the handle 103 is connected to the bracket 102. The handle 103 provides the user with a handle for operating the device. The handle 103 is designed in accordance with ergonomic principles to ensure that the user can comfortably hold the handle 103 when operating the device. Understandably, the user controls the direction and speed of the device by holding the handle 103.

[0043] Additionally, a tray 104 is provided at the bottom of the housing 101, which can hold tools or spare seeds needed during the planting process. The tray 104 is installed on the protective housing or bracket 102, making it easy for the user to access the items carried by the tray 104 at any time. Understandably, during the planting process, there may be situations where it is necessary to change tools or replenish seeds, and the presence of the tray 104 provides convenience for the user.

[0044] In some examples, such as Figure 2 As shown, the inner cavity of the housing 101 includes a feeding area, and the feeding mechanism 400 is disposed in the feeding area.

[0045] The feeding mechanism 400 includes a pelletizing component 402, which is connected to the housing 101 via a corresponding rotating shaft, allowing the pelletizing component 402 to rotate within the housing 101. The surface of the pelletizing component 402 is provided with several pellet-collecting openings 403. When the pelletizing component 402 is approximately disc-shaped, each pellet-collecting opening 403 is located on the arc surface of the pelletizing component 402, and the openings 403 are evenly distributed circumferentially.

[0046] Furthermore, the housing 101 is provided with an extension structure 401, which extends from the inner wall of the housing 101 to the outer side of the pelletizing component 402. Specifically, the extension structure 401 can be integrally formed with the housing 101, or the extension structure 401 can be separate from the housing 101 and fixedly connected to the housing 101. That is, the extension structure 401 defines a space for accommodating the pelletizing component 402, and the shape of this space is approximately the same as the shape of the pelletizing component 402. Specifically, the extension structure 401 closes each pellet receiving port 403 without affecting the free rotation of the pelletizing component 402.

[0047] In addition, the extension structure 401 defines a guide channel 406 that connects to the pelleting component 402. The guide channel 406 is located at the bottom of the pelleting component 402, and the size of the guide channel 406 corresponds to the size of the pellet receiving port 403. During the rotation of the pelleting component 402, the extension structure 401 has a sealing effect on the pellet receiving port 403, preventing seeds in the pellet receiving port 403 that have not reached the guide channel 406 from leaving the port 403. When the pellet receiving port 403 reaches the position of the guide channel 406, the seeds in the pellet receiving port 403 are immediately guided into the guide channel 406, completing the feeding operation of this device.

[0048] Meanwhile, the automatic seeding device uses a seeding mechanism 200 to perform the seeding operation. The seeding mechanism 200 includes a seeding channel aligned with the planting hole, and the seeds are introduced into the seeding channel along the feed channel 406. When the seeds are introduced into the seeding channel, they fall into the planting hole along the seeding channel, thus completing the seeding operation.

[0049] Optionally, the feeding mechanism 400 also includes a connecting channel 407. The feeding channel 407 can be defined by a corresponding pipe fitting. One end of the connecting channel 407 is connected to the guide channel 406, and the other end extends to the sowing channel, thereby conveying the seeds in the guide channel 406 to the sowing channel. Specifically, the connecting channel 407 is inclined, and the inclination angle and length of the connecting channel 407 should be designed according to the size and flowability of the seeds to ensure that the seeds can slide smoothly into the sowing channel.

[0050] In some examples, such as Figure 2 and 3 As shown, the surface of the grain separating component 402 is provided with a plurality of grain separating grooves 404, which define the position of the grain receiving port 403. The grain separating grooves 404 are evenly distributed in a circle on the surface of the grain separating component 402, and the grain receiving port 403 is used to receive the seed.

[0051] The depth of the grain separating trough 404 is greater than the depth of the grain receiving port 403, which is connected to the inside of the grain separating trough 404 via a first length adjusting component 405. Specifically, the first length adjusting component 405 is a telescopic rod, and its extension direction is radial to that of the grain separating component 402. When the length of the first length adjusting component 405 increases, the distance from the grain receiving port 403 to the outer edge of the grain separating component 402 decreases; conversely, when the length of the first length adjusting component 405 decreases, the distance from the grain receiving port 403 to the outer edge of the grain separating component 402 increases.

[0052] Understandably, the material of the grain separating trough 404 should have a certain strength and hardness to withstand the movement force of the first length adjusting component 405. The material of the grain receiving port 403 should have a certain degree of wear resistance and corrosion resistance to withstand the friction and pressure of the seeds.

[0053] Specifically, when only one seed needs to be sown at a time, the length of the first length adjusting component 405 increases, allowing the seed-receiving port 403 to hold only one seed; when multiple seeds need to be sown at once, the length of the first length adjusting component 405 decreases, allowing the seed-receiving port 403 to hold multiple seeds at once. When a seed reaches the seed-receiving port 403, the seed-dividing component 402 rotates downward under pressure, feeding the seed into the guide channel 406. The seed-dividing component 402 can flexibly adjust the number of seeds sown according to different planting needs, improving planting accuracy and efficiency. It is understood that the seed-dividing component 402 can also be equipped with a corresponding driver to facilitate control of its rotation speed.

[0054] In some examples, such as Figure 2 As shown, to facilitate the entry of seeds into the device, the extension structure 401 also defines a feeding channel 408 that connects to the seed-dividing component 402. The feeding channel 408 is located at the top of the seed-dividing component 402, and the seed-receiving port 403 receives seeds through the feeding channel 408.

[0055] The feeding channel 408 forms a feeding port at the top of the housing 101, and a feeding port fence 409 is provided at the edge of the feeding port. The feeding port fence 409 can prevent seeds from spilling when poured into the feeding port. At the same time, the feeding port fence 409 can also prevent external debris from entering the feeding port and affecting the normal feeding of seeds.

[0056] Specifically, the horizontal dimension of the feed channel 408 gradually decreases towards the seed-dividing component 402, giving it a funnel shape to facilitate smooth seed feeding. After the seeds are poured into the feed channel 408, they automatically slide downwards to the seed-dividing component 402 due to gravity. The funnel-shaped feed channel 408 makes the seeds more concentrated during feeding, reducing seed dispersion and clogging. It can be understood that the dimension of the feed channel 408 at the point connecting to the seed-dividing component 402 corresponds to the dimension of the seed-receiving opening 403, ensuring that the seeds enter each seed-receiving opening 403 sequentially.

[0057] In addition, some guide vanes or other auxiliary structures can be set in the feeding area to guide the flow direction of the seeds and improve the feeding efficiency.

[0058] In some examples, such as Figure 4 and Figure 5 As shown, the sowing mechanism 200 includes a sowing tube 201 and a sowing turntable 203. The inner cavity of the sowing tube 201 defines a sowing channel, and the sowing turntable 203 is connected to the housing 101 through a corresponding rotating shaft to ensure that the sowing turntable 203 can rotate.

[0059] The seeding turntable 203 is linked with the seeding tube 201. The seeding turntable 203 drives the seeding tube 201 to move back and forth by rotating, so that the seeding tube 201 extends into the bottom of the planting hole and introduces the seeds into the bottom of the planting hole.

[0060] Meanwhile, the side wall of the seeding tube 201 is provided with a seeding port 202, the shape of which corresponds to the shape of the connecting channel 407. When the seeding tube 201 moves downward under the driving force of the seeding turntable 203, the seeding port 202 gradually approaches and connects with the connecting channel 407, allowing a predetermined number of seeds in the connecting channel 407 to be introduced into the seeding channel along the seeding port 202. It is understood that when the seeding port 202 and the connecting channel 407 are isolated from each other, the seeds cannot enter the seeding channel.

[0061] Furthermore, the inner wall of the shell 101 defines a sowing area, in which the sowing mechanism 200 performs sowing operations. The soil conditions and humidity at the bottom of the sowing mechanism 200 affect seed germination and growth. Therefore, when designing the device, it is necessary to consider the sowing requirements under different soil conditions, select appropriate materials and sizes for the sowing tube 201, and choose appropriate sowing depths and spacing.

[0062] Specifically, the material of the seeding tube 201 should have a certain strength and flexibility to move smoothly in the soil. The inner diameter and length of the seeding tube 201 should be selected according to the size of the seeds and planting needs to ensure that the seeds can pass smoothly through the seeding tube 201 into the soil.

[0063] In some examples, the sowing mechanism 200 includes a sowing rocker arm 204, with the first end of the sowing rocker arm 204 hinged to the sowing turntable 203 and the second end of the sowing rocker arm 204 hinged to the sowing tube 201. Thus, the sowing rocker arm 204 and the sowing tube 201 form a linkage mechanism, which facilitates the sowing turntable 203 to drive the sowing tube 201 to reciprocate.

[0064] The first end of the sowing rocker arm 204 is hinged to the sowing turntable 203, and its position can be adjusted to regulate the reciprocating stroke of the sowing tube 201. It can be understood that the reciprocating stroke of the sowing tube 201 is adjusted according to the depth of the planting hole to facilitate the introduction of seeds to the bottom of the planting hole.

[0065] Specifically, the end face of the sowing turntable 203 is provided with a guide groove extending along the axial direction. Inside the guide groove are a second length adjustment component 205 and a corresponding connector connected to each other. The connector is hinged to the sowing rocker arm 204. The change in length of the second length adjustment component 205 can change the position of the sowing rocker arm 204 hinged to the sowing turntable 203, and thus adjust the stroke of the sowing tube 201 reciprocating.

[0066] In addition, the length and angle of the sowing rocker 204 should be designed according to the movement requirements of the sowing tube 201 to ensure that the sowing tube 201 can accurately complete the sowing operation. The rotation speed and angle of the sowing turntable 203 will also affect the sowing efficiency and quality of the sowing tube 201. Therefore, when designing the device, it is necessary to select the appropriate size of the sowing turntable 203 and the transmission ratio according to the actual needs.

[0067] In some examples, such as Figure 6 As shown, the housing 101 is provided with a rotatable roller assembly, which includes a synchronously rotating roller body 107 and a drive wheel 108. Specifically, the roller body 107 is rotatably connected to the bottom of the housing 101 via a corresponding shaft, the roller body 107 rotates synchronously with the shaft, and the drive wheel 108 is fixedly mounted on the shaft at this location.

[0068] Among them, the drive wheel 108 is one of the core components of the power transmission of this device. The drive wheel 108 transmits power to the seeding turntable 203 through the transmission component, so that the movement of this device is linked with the rotation of the seeding turntable 203.

[0069] Specifically, the drive wheel 108 is a sprocket, and the surface of the seeding turntable 203 is also equipped with a sprocket; the two are connected by a transmission chain. Understandably, the design of parameters such as the size and number of teeth of the drive wheel 108 will affect the transmission ratio and working efficiency of the device.

[0070] Furthermore, the roller body 107 employs an anti-sinking design, comprising an inner rim and an outer rim to increase the contact area between the roller body 107 and the soil. The inner and outer rims fit together at their ends and are both inclined towards the center, allowing the anti-sinking roller body 107 to better distribute the weight of the device when traveling through the soil, preventing the device from sinking into the soil. During planting, the device needs to operate under different soil conditions; the roller body 107 effectively improves the device's passability, ensuring the smooth progress of planting work.

[0071] Understandably, the housing 101 is equipped with an anti-sinking wheel fixing component to cooperate with the corresponding rotating shaft to connect the anti-sinking wheel, ensuring that the anti-sinking wheel will not loosen or fall off during the operation of the device. The anti-sinking wheel fixing component is usually made of high-strength material and has good fastening performance. When installing the anti-sinking wheel, the anti-sinking wheel fixing component can firmly fix the anti-sinking wheel to the bracket 102 or the housing 101, ensuring the stability and safety of the device.

[0072] In some examples, such as Figure 4 and Figure 5As shown, the automatic seeding device includes a perforating mechanism 300. The inner wall of the housing 101 defines a perforation area. The perforating mechanism 300 is located in the perforation area and is used to perforate the soil to facilitate the subsequent introduction of seeds into the planting holes. It is understood that the perforation operation needs to be carried out before the sowing operation, so the perforating mechanism 300 is closer to the front end of the device than the sowing mechanism 200.

[0073] The punching mechanism 300 includes a punching rod 301 and a punching turntable 302. The punching rod 301 is a solid rod, and the punching turntable 302 is connected to the housing 101 via a corresponding rotating shaft, enabling the punching turntable 302 to rotate. Similar to the sowing mechanism 200, the punching turntable 302 is linked to the punching rod 301, and the rotation of the punching turntable 302 drives the punching rod 301 to reciprocate.

[0074] Specifically, such as Figure 7 and Figure 8 As shown, both the perforating turntable 302 and the sowing turntable 203 have sprockets on their end faces, and are connected via corresponding transmission chains. Therefore, the end face of the sowing turntable 203 has two parallel sprockets, which are respectively connected to the drive wheel 108 and the perforating turntable 302. As the device moves, the drive wheel 108 drives the sowing turntable 203 to rotate, which in turn drives the perforating turntable 302 to rotate, thus achieving the overall transmission connection of the device.

[0075] Understandably, the number of teeth and other parameters of each sprocket should be selected according to the transmission design requirements to ensure accurate transmission ratio. The material of the transmission chain should have certain wear resistance and corrosion resistance to maintain good performance during long-term use.

[0076] Furthermore, the soil conditions and hardness at the bottom of the drilling mechanism 300 affect the drilling effect of the drilling rod 301. Therefore, when designing the device, it is necessary to consider the drilling requirements under different soil conditions and select appropriate materials and dimensions for the drilling rod 301. The drilling rod 301 is the main executing component for the drilling operation. The material of the drilling rod 301 should have sufficient strength and hardness to successfully drill holes in the soil. The diameter and length of the drilling rod 301 should be selected according to planting needs to ensure that the size and depth of the formed holes meet the growth requirements of the seeds. During the drilling process, the drilling rod 301 needs to withstand resistance and friction from the soil; therefore, its surface should be properly treated to improve wear resistance and corrosion resistance.

[0077] In some examples, the punching mechanism 300 includes a punching rocker arm 303, with the first end of the punching rocker arm 303 hinged to the punching turntable 302 and the second end of the punching rocker arm 303 hinged to the punching rod 301. Thus, the punching rocker arm 303 and the punching tube form a linkage mechanism, which facilitates the punching turntable 302 to drive the punching tube to reciprocate.

[0078] The first end of the punching rocker 303 is hinged to the punching turntable 302, allowing for adjustment of the stroke of the punching tube's reciprocating movement. It can be understood that the stroke of the punching tube is adjusted according to the required depth of the planting hole, ensuring that the planting hole depth meets the current seed growth needs.

[0079] Specifically, the end face of the drilling turntable 302 is provided with a guide groove extending along the axial direction. Inside the guide groove are a third length adjustment component 304 and a corresponding connector connected to each other. The connector is hinged to the drilling rocker 303. The change in the length of the third length adjustment component 304 can change the position of the drilling rocker 303 hinged to the drilling turntable 302, and adjust the stroke of the reciprocating movement of the drilling tube in this way.

[0080] In addition, the length and angle of the punching rocker 303 should be designed according to the movement requirements of the punching tube to ensure that the punching tube can accurately complete the punching operation. The rotation speed and angle of the punching turntable 302 will also affect the punching efficiency and quality of the punching tube. Therefore, when designing the device, it is necessary to select the appropriate size of the punching turntable 302 and the transmission ratio according to the actual needs.

[0081] In some examples, the housing 101 is provided with a seeding guide hole 105 and a punching guide hole 106. The seeding guide hole 105 is used to limit the movement of the seeding tube 201 and prevent its rotation. The punching guide hole 106 is used to limit the movement of the punching rod 301 and prevent its rotation.

[0082] The size and position of the sowing guide hole 105 correspond to the size and position of the sowing tube 201, allowing the sowing tube 201 to move smoothly within the sowing guide hole 105, thereby guiding the movement of the sowing tube 201. Similarly, the size and position of the punching guide hole 106 correspond to the size and position of the punching rod 301, allowing the punching rod 301 to move smoothly within the punching guide hole 106, thereby guiding the movement of the punching rod 301. It is understandable that during the planting process, the punching rod 301 and the sowing tube 201 need to frequently extend into and retract into the soil; the existence of the corresponding guide holes ensures the accurate movement trajectory of both, improving planting precision and efficiency.

[0083] In some examples, such as Figure 2 As shown, the automatic seeding device includes a rolling mechanism 500. After the seeds are introduced into the planting hole, the rolling mechanism 500 compacts the soil to promote seed germination and production.

[0084] The rolling mechanism 500 includes a pressure roller 501 and a pressure roller support 502. The pressure roller 501 is hinged to the bottom of the housing 101 via the pressure roller support 502. When the pressure roller support 502 rotates relative to the housing 101, the distance between the pressure roller 501 and the ground changes.

[0085] Specifically, the pressure roller 501 is fixed to the bottom of the housing 101 by the pressure roller bracket 502, the pressure roller bracket fixing member, and the pressure roller bracket rotating member. The pressure roller bracket 502 has a certain length, the pressure roller bracket rotating member is formed as a rotating shaft, and the pressure roller bracket fixing member is used to install the pressure roller bracket rotating member.

[0086] During use, when it is necessary to cover and compact the planting holes where seeds have been introduced, the pressure roller 501 can be placed on the ground by rotating the pressure roller bracket 502. The pressure roller bracket 502 provides stable support for the pressure roller 501, and the fixing and rotating parts of the pressure roller bracket allow the height of the pressure roller 501 to be flexibly adjusted. After the pressure roller 501 is placed on the ground, as the device moves forward, the pressure roller 501 will compact the soil, ensuring close contact between the seeds and the soil, which is beneficial to seed germination and growth.

[0087] Specifically, the rotating component of the pressure roller bracket allows the pressure roller bracket 502 to rotate within a certain angle range, enabling the pressure roller 501 to adjust its height and angle as needed. During planting, when soil compaction is required, the pressure roller 501 is placed on the ground by operating the rotating component of the pressure roller bracket; when compaction is not required, the pressure roller 501 is raised to reduce the resistance of the device. Additionally, the pressure roller bracket 502 can be equipped with a locking component, which locks the pressure roller bracket 502 to the target height.

[0088] In actual implementation, the various components cooperate and work together. First, the user pours the seeds into the feeding channel 408. Under the action of gravity, and blocked by the feeding port fence 409, the seeds enter the device. The seeds continue to slide downwards and enter the receiving port 403 of the seed-separating component 402. As the seed-separating component 402 rotates, the receiving port 403 rotates to the guiding channel 406. The seeds reach the position of the sowing tube 201 through the guiding channel 406 and the connecting channel 407.

[0089] As the device moves forward, the drive wheel 108 drives the sowing turntable 203 and the punching turntable 302 to rotate, causing the punching rod 301 and the sowing tube 201 to perform punching and sowing operations sequentially. During the sowing operation, the movement of the sowing tube 201 causes the sowing port 202 to connect with the connecting channel 407, allowing the seeds to enter the sowing tube 201 and further reach the bottom of the planting hole.

[0090] Furthermore, when only one seed needs to be sown at a time, the length of the first length adjusting component 405 increases, so that the seed-receiving port 403 can only hold one seed. When multiple seeds need to be sown at once, the length of the first length adjusting component 405 decreases, so that the seed-receiving port 403 can hold multiple seeds at once.

[0091] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
