Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0037] like Figure 1 As shown, an embodiment of the present application provides an automatic sowing device, which includes a housing 101, a sowing mechanism 200 and a feeding mechanism 400. Specifically, the automatic sowing device is used for planting peanuts.

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

[0039] In some examples, the housing 101 is hollow, and the sowing mechanism 200 and the feeding mechanism 400 are both 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, thereby improving the structural strength of the entire device.

[0040] The top of the front end of the housing 101 is provided with a downward slope, which is convenient for the user to observe the road conditions ahead when operating the device for automatic sowing, and helps to adjust the direction of the device in real time, so that the device can avoid obstacles or areas not suitable for planting in time. In addition, the housing 101 can also prevent external debris from entering the interior of the device and affecting the normal operation of the various mechanisms in the housing 101.

[0041] Furthermore, a bracket 102 is fixedly connected to the surface of the shell 101. Specifically, the bracket 102 is located outside the shell 101. The bracket 102 can support the device and provide a stable installation position for each component. It can be understood that the bracket 102 has high strength and stability, so that the device can withstand various forces during the planting process. During the movement of the device, the bracket 102 can effectively disperse the reaction force from the ground to ensure the smooth operation of the device.

[0042] At the same time, a handle 103 is provided at the rear end of the automatic seeding device, and the handle 103 is connected to the housing 101, or the handle 103 is connected to the bracket 102. The handle 103 provides a handle for the user to operate the device, and the design of the handle 103 conforms to the principle of ergonomics to ensure that the user can comfortably hold the handle 103 when operating the device. It can be understood that the user controls the direction and speed of the device by holding the handle 103.

[0043] In addition, a support plate 104 is provided at the bottom of the housing 101, and the support plate 104 can be used to place tools or spare seeds needed during the planting process. The support plate 104 is installed on the protective housing or the bracket 102, so that the user can take the items carried by the support plate 104 at any time. It is understandable that during the planting process, it may be necessary to replace tools or replenish seeds, and the presence of the support plate 104 provides convenience for the user.

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

[0045] The feeding mechanism 400 includes a particle-classifying component 402, which is connected to the housing 101 via a corresponding rotating shaft, so that the particle-classifying component 402 can rotate inside the housing 101. Meanwhile, a plurality of particle-receiving openings 403 are provided on the surface of the particle-classifying component 402. When the particle-classifying component 402 is roughly formed into a disc shape, each particle-receiving opening 403 is provided on the arc surface of the particle-classifying component 402, and each particle-receiving opening 403 is evenly distributed around the circumference.

[0046] Further, the shell 101 is provided with an extension structure 401, and the extension structure 401 extends from the inner wall of the shell 101 to the outer side of the particle-classifying component 402. Specifically, the extension structure 401 can be integrally formed with the shell 101, or the extension structure 401 is separated from the shell 101 and fixedly connected to the shell 101. That is, the extension structure 401 defines a space for accommodating the particle-classifying component 402, and the shape of the space is approximately consistent with the shape of the particle-classifying component 402. Specifically, the extension structure 401 closes each particle-receiving opening 403 without affecting the free rotation of the particle-classifying component 402.

[0047] In addition, the extension structure 401 defines a material guide channel 406 connected to the grain-classifying component 402. The material guide channel 406 is located at the bottom of the grain-classifying component 402, and the size of the material guide channel 406 corresponds to the size of the grain-receiving opening 403. During the rotation of the grain-classifying component 402, the extension structure 401 has a sealing effect on the grain-receiving opening 403, thereby preventing the seeds in the grain-receiving opening 403 that have not reached the material guide channel 406 from escaping from the grain-receiving opening 403; when the grain-receiving opening 403 reaches the position of the material guide channel 406, the seeds in the grain-receiving opening 403 are immediately introduced into the material guide channel 406, completing the feeding operation of the device.

[0048] At the same time, the automatic sowing device uses a sowing mechanism 200 to perform sowing operations. The sowing mechanism 200 includes a sowing channel aligned with the planting hole, and the seeds are introduced into the sowing channel along the guide channel 406. When the seeds are introduced into the sowing channel, the seeds fall into the planting hole along the sowing channel to complete the sowing operation.

[0049] Optionally, the feeding mechanism 400 further includes a connecting channel 407, and the feeding channel 408 can be defined by corresponding pipe fittings, one end of the connecting channel 407 is connected to the material guiding channel 406, and the other end extends to the sowing channel, so as to transport the seeds in the material guiding 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 fluidity 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-classifying component 402 is provided with a plurality of grain-classifying grooves 404, which define the position of the grain-receiving opening 403. The grain-classifying grooves 404 are evenly distributed in a circle on the surface of the grain-classifying component 402, and the grain-receiving opening 403 is used to receive seeds.

[0051] The depth of the grain-classifying groove 404 is greater than the depth of the grain-receiving opening 403, and the grain-receiving opening 403 is connected to the inside of the grain-classifying groove 404 through a first length-adjusting component 405. Specifically, the first length-adjusting component 405 adopts a telescopic rod, and the extension direction of the first length-adjusting component 405 is the radial direction of the grain-classifying component 402. When the length of the first length-adjusting component 405 increases, the distance from the grain-receiving opening 403 to the outer edge of the grain-classifying component 402 decreases; when the length of the first length-adjusting component 405 decreases, the distance from the grain-receiving opening 403 to the outer edge of the grain-classifying component 402 increases.

[0052] It is understandable that the material of the seed separation groove 404 should have certain strength and hardness to withstand the movement force of the first length adjustment component 405. The material of the seed receiving opening 403 should have certain wear resistance and corrosion resistance to withstand the friction and pressure of the seeds.

[0053] Specifically, when it is necessary to sow one seed at a time, the length of the first length adjustment component 405 increases so that the grain receiving opening 403 can only load one seed; when it is necessary to sow multiple seeds at a time, the length of the first length adjustment component 405 decreases so that the grain receiving opening 403 can load multiple seeds at a time. When the seeds reach the grain receiving opening 403, the grain separation component 402 rotates downward under pressure to send the seeds into the material guide channel 406. The grain separation component 402 can flexibly adjust the number of seeds sown according to different planting needs to improve the accuracy and efficiency of planting. It is understandable that the grain separation component 402 can also be equipped with a corresponding driver to facilitate the control of the rotation speed of the grain separation component 402.

[0054] In some examples, such as Figure 2 As shown, to facilitate seeds to enter the device, the extension structure 401 further defines a feed channel 408 connected to the grain-classifying component 402 . The feed channel 408 is located at the top of the grain-classifying component 402 , and the grain-receiving opening 403 receives seeds through the feed channel 408 .

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

[0056] Specifically, the horizontal dimension of the feed channel 408 gradually decreases in the direction close to the grain-separating component 402, so that the feed channel 408 presents a funnel shape, which is convenient for the smooth feeding of seeds. After the seeds are poured into the feed channel 408, due to the effect of gravity, the seeds will automatically slide down to the grain-separating component 402. The funnel-shaped feed channel 408 makes the seeds more concentrated during the feeding process, reducing the dispersion and blockage of the seeds. It is understandable that the size of the feed channel 408 at the position connected to the grain-separating component 402 corresponds to the size of the grain-receiving opening 403, ensuring that the seeds enter each grain-receiving opening 403 in sequence.

[0057] In addition, some guide plates 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 disc 203. The inner cavity of the sowing tube 201 defines a sowing channel, and the sowing disc 203 is connected to the housing 101 through a corresponding rotating shaft to ensure that the sowing disc 203 can rotate.

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

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

[0061] Furthermore, the inner wall of the housing 101 defines a sowing area, and the sowing mechanism 200 performs sowing operations in the sowing area. The soil conditions and humidity at the bottom of the sowing mechanism 200 will affect the germination and growth of seeds, so when designing the device, it is necessary to consider the sowing requirements under different soil conditions, select the appropriate material and size of the sowing tube 201, and the appropriate sowing depth and spacing.

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

[0063] In some examples, the sowing mechanism 200 includes a sowing rocker 204, a first end of the sowing rocker 204 is hinged to the sowing turntable 203, and a second end of the sowing rocker 204 is hinged to the sowing tube 201, so that the sowing rocker 204 and the sowing tube 201 form a connecting rod mechanism, so that the sowing turntable 203 drives the sowing tube 201 to reciprocate.

[0064] The position at which the first end of the sowing rocker 204 is hinged to the sowing turntable 203 can be adjusted, thereby adjusting the reciprocating stroke of the sowing tube 201. It is understandable that the reciprocating stroke of the sowing tube 201 is adjusted according to the depth of the planting hole, so as to facilitate the introduction of seeds into the bottom of the planting hole.

[0065] Specifically, the end face of the sowing turntable 203 is provided with a guide groove extending axially, and the interior of the guide groove is provided with a second length adjustment component 205 and a corresponding connecting piece which are interconnected. The connecting piece is hinged to the sowing rocker 204. The length change of the second length adjustment component 205 can change the position at which the sowing rocker 204 is hinged to the sowing turntable 203, and in this way adjust the reciprocating stroke of the sowing tube 201.

[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 a suitable size and transmission ratio of the sowing turntable 203 according to 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 driving wheel 108. Specifically, the roller body 107 is rotatably connected to the bottom of the housing 101 through a corresponding rotating shaft, the roller body 107 rotates synchronously with the rotating shaft, and the driving wheel 108 is fixedly arranged on the rotating shaft there.

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

[0069] Specifically, the driving wheel 108 adopts a sprocket wheel, and the surface of the sowing turntable 203 is also provided with a sprocket wheel, and the two are connected by a transmission chain. It is understandable that the design of parameters such as the size and number of teeth of the driving wheel 108 will affect the transmission ratio and working efficiency of the device.

[0070] In addition, the roller body 107 uses an anti-sinking wheel, and the roller body 107 includes an inner rim and an outer rim, thereby increasing the contact area between the roller body 107 and the soil. The inner rim and the outer rim fit each other at the ends and are both inclined toward the middle, so that when the anti-roller body 107 is traveling in the soil, the weight of the device can be better dispersed to prevent the device from sinking into the soil. During the planting process, the device needs to travel under different soil conditions, and the roller body 107 can effectively improve the passability of the device and ensure the smooth progress of the planting work.

[0071] It is understandable that the housing 101 is provided with an anti-sinking wheel fixing member for connecting the anti-sinking wheel with the corresponding rotating shaft to ensure that the anti-sinking wheel will not loosen or fall off during the driving of the device. The anti-sinking wheel fixing member is usually made of high-strength material and has good fastening performance. When installing the anti-sinking wheel, the anti-sinking wheel fixing member can firmly fix the anti-sinking wheel to the bracket 102 or the housing 101 to ensure 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 punching mechanism 300. The inner wall of the housing 101 defines a punching area. The punching mechanism 300 is located in the punching area and is used to punch holes in the soil to facilitate the subsequent introduction of seeds into the planting holes. It can be understood that the punching operation needs to be implemented before the seeding operation. Therefore, compared with the seeding mechanism 200, the punching mechanism 300 is closer to the front end of the device.

[0073] The punching mechanism 300 includes a punching rod 301 and a punching disc 302. The punching rod 301 is a solid rod. The punching disc 302 is connected to the housing 101 through a corresponding rotating shaft so that the punching disc 302 can rotate. Similar to the sowing mechanism 200, the punching disc 302 is linked to the punching rod 301, and the punching disc 302 drives the punching rod 301 to reciprocate by rotating.

[0074] Specifically, Figure 7 and Figure 8 As shown, the end surface of the punching disc 302 is provided with a sprocket, and the end surface of the sowing disc 203 is also provided with a sprocket, and the punching disc 302 and the sowing disc 203 are connected through a corresponding transmission chain. Therefore, the end surface of the sowing disc 203 is provided with two parallel sprockets, which are respectively connected to the driving wheel 108 and the punching disc 302. As the device moves forward, the driving wheel 108 drives the sowing disc 203 to rotate, and the sowing disc 203 then drives the punching disc 302 to rotate, thereby realizing the transmission connection of the entire device.

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

[0076] In addition, the soil conditions and hardness at the bottom of the punching mechanism 300 will affect the punching effect of the punching rod 301. Therefore, when designing the device, it is necessary to consider the punching requirements under different soil conditions and select the appropriate material and size of the punching rod 301. The punching rod 301 is the main execution component of the punching operation. The material of the punching rod 301 should have sufficient strength and hardness to be able to punch holes in the soil smoothly. The diameter and length of the punching rod 301 should be selected according to the planting requirements to ensure that the size and depth of the holes formed meet the growth requirements of the seeds. During the punching process, the punching rod 301 needs to withstand the resistance and friction from the soil, so 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 303, the first end of the punching rocker 303 is hinged to the punching turntable 302, and the second end of the punching rocker 303 is hinged to the punching rod 301, so that the punching rocker 303 and the punching tube form a connecting rod mechanism to facilitate the punching turntable 302 to drive the punching tube to reciprocate.

[0078] The position where the first end of the perforating rocker 303 is hinged to the perforating turntable 302 can be adjusted, thereby adjusting the reciprocating stroke of the perforating tube. It is understandable that the reciprocating stroke of the perforating tube is adjusted according to the required depth of the planting hole to ensure that the depth of the planting hole meets the current seed growth requirements.

[0079] Specifically, the end face of the punching turntable 302 is provided with a guide groove extending axially, and the interior of the guide groove is provided with a third length adjustment component 304 and a corresponding connecting piece that are interconnected. The connecting piece is hinged to the punching rocker 303. The change in the length of the third length adjustment component 304 can change the position at which the punching rocker 303 is hinged to the punching turntable 302, and in this way adjust the reciprocating stroke of the punching tube.

[0080] In addition, the length and angle of the punch rocker 303 should be designed according to the movement requirements of the punch tube to ensure that the punch 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 punch tube. Therefore, when designing the device, it is necessary to select a suitable size and transmission ratio of the punching turntable 302 according to actual needs.

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

[0082] Among them, the size and position of the sowing guide hole 105 correspond to the size and position of the sowing tube 201, so that the sowing tube 201 can move smoothly in the sowing guide hole 105, thereby guiding the movement of the sowing tube 201; the size and position of the punching guide hole 106 correspond to the size and position of the punching rod 301, so that the punching rod 301 can move smoothly in the punching guide hole 106, thereby guiding the movement of the punching rod 301. It can be understood that during the planting process, the punching rod 301 and the sowing tube 201 need to be frequently extended into the soil and retracted. The existence of the corresponding guide holes can ensure that the movement trajectories of the two are accurate and improve the accuracy and efficiency of planting.

[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 holes, the rolling mechanism 500 compacts the soil to promote the germination and production of the seeds.

[0084] The rolling mechanism 500 includes a pressing wheel 501 and a pressing wheel bracket 502, wherein the pressing wheel 501 is hinged to the bottom of the housing 101 through the pressing wheel bracket 502. When the pressing wheel bracket 502 rotates relative to the housing 101, the distance between the pressing wheel 501 and the ground changes.

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

[0086] During use, when it is necessary to cover and compact the planting hole into which the seeds have been introduced, the pressing wheel 501 can be placed on the ground by rotating the pressing wheel bracket 502. The pressing wheel bracket 502 provides stable support for the pressing wheel 501, and the pressing wheel bracket fixing part and the pressing wheel bracket rotating part enable the pressing wheel 501 to flexibly adjust the height. After the pressing wheel 501 is placed on the ground, as the device moves forward, the pressing wheel 501 will compact the soil to ensure that the seeds are in close contact with the soil, which is conducive to the germination and growth of the seeds.

[0087] Specifically, the roller bracket rotating member allows the roller bracket 502 to rotate within a certain angle range, so that the roller 501 can adjust the height and angle as needed. During the planting process, when the soil needs to be compacted, the roller 501 is placed on the ground by operating the roller bracket rotating member; when compaction is not required, the roller 501 is lifted to reduce the resistance of the device. In addition, the roller bracket 502 can be additionally provided with a locking component, and the roller bracket 502 is locked at the target height by the locking component.

[0088] In the actual implementation process, the various components cooperate with each other and work in coordination. First, the user pours the seeds into the feed channel 408. Under the action of gravity and the blocking of the feed port fence 409, the seeds enter the device. The seeds continue to slide downward and enter the grain receiving port 403 of the grain sorting component 402. As the grain sorting component 402 rotates, the grain receiving port 403 rotates to the material guide channel 406. The seeds pass through the material guide channel 406 and the connecting channel 407 to reach the position of the sowing tube 201.

[0089] As the device as a whole moves forward, the driving wheel 108 drives the sowing turntable 203 and the punching turntable 302 to rotate, so that the punching operation and the sowing operation of the punching rod 301 and the sowing tube 201 are carried out successively. During the sowing operation, the movement of the sowing tube 201 causes the sowing port 202 to connect with the connecting channel 407, so that the seeds enter the sowing tube 201 and further reach the bottom of the planting hole.

[0090] In addition, when it is necessary to sow one seed at a time, the length of the first length adjusting component 405 increases so that only one seed can be loaded into the seed receiving opening 403. When it is necessary to sow multiple seeds at a time, the length of the first length adjusting component 405 decreases so that the seed receiving opening 403 can load multiple seeds at a time.

[0091] The above is a detailed description of the implementation methods of the present application in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods. Various changes can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
