Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, and more specifically, to a seeding machine. Background Technology

[0002] my country's mountainous and hilly regions exhibit significant spatial heterogeneity in their arable land resources. On the one hand, due to topographical constraints, arable land is generally fragmented, characterized by scattered spatial distribution, irregular field boundaries, and significant area differences, with adjacent fields often exhibiting an elevation difference of 1-3 meters. On the other hand, due to historically formed land ownership relationships, arable land within the same area often involves multiple operators, resulting in complex contractual relationships. This unique topographical condition and property rights structure pose a severe challenge to traditional agricultural mechanization—standardized wheeled tractors and other large agricultural machinery are ill-suited for the needs of moving between irregular fields. Frequent field changes not only significantly reduce operational efficiency but also increase the risk of accidents such as machinery overturning. Especially during the crucial spring and autumn planting seasons, farmers are often forced to revert to manual and animal-powered farming methods, severely hindering the modernization of agriculture in mountainous areas. Summary of the Invention

[0003] This invention provides a seeding machine that improves upon the problem of large agricultural implements used in seeding operations being difficult to move flexibly between different fields, enabling more flexible movement between different fields.

[0004] To achieve the above objectives, the present invention provides a seeding machine, comprising:

[0005] A traction device, the traction device comprising a vehicle body and a moving system, the moving system being mounted on the vehicle body and the moving system being configured to rotate at least partially to drive the vehicle body to move;

[0006] A connecting device is rotatably connected to the vehicle body, and the plane of rotation of the connecting device is parallel to the plane of rotation of the moving device;

[0007] A sowing device includes a sowing wheel and a wheel frame, the wheel frame being connected to a connecting device, and the sowing wheel being rotatably connected to the wheel frame. In use, the sowing machine is deployed in a field, the moving system contacts the ground, and the sowing wheel is filled with crop seeds. During sowing, the moving system drives the vehicle body to move, and the sowing wheel rolls under the traction of the vehicle body, sowing the crop seeds in the field. Because the connecting device is rotatably connected to the vehicle body, the sowing wheel rolls forward with the vehicle body, allowing for more uniform pressure contact with the soil, thus stabilizing the sowing depth. Since this traction device replaces standardized wheeled tractors and other large agricultural implements, its size and weight are significantly reduced, its flexibility is improved, it is easy to move between different fields, and it can adapt to fields with irregular edges.

[0008] As an optional technical solution, the seeding wheel includes a wheel body and a seeding component. The wheel body includes an outer peripheral surface and two side surfaces. The two side surfaces are arranged opposite to each other and connected to the outer peripheral surface. The two side surfaces and the outer peripheral surface enclose an internal space. The outer peripheral surface is provided with a plurality of mounting ports. The mounting ports extend from the outside of the outer peripheral surface to the internal space. The plurality of mounting ports are distributed circumferentially along the outer peripheral surface.

[0009] The sowing assembly includes a sowing tube, a sealing plate, and a lever. The sowing tube passes through the mounting opening and slides into it, connecting the internal space to the outside of the wheel. The sealing plate covers the opening of the sowing tube on the side opposite to the wheel and is hinged to the side of the sowing tube near the wheel, with its hinge axis parallel to the wheel's rotation axis. The side of the sealing plate near the wheel has a connecting portion, which has a connecting position and a disengaging position along the sliding direction of the sowing tube, wherein the connecting position is closer to the wheel than the disengaging position. The lever is at least partially parallel or coaxial with the hinge axis between the sowing tube and the sealing plate, and slides along the direction from the connecting position to the disengaging position to the connecting portion. The lever is used to connect the connecting position to drive the sealing plate to rotate relative to the sowing tube, or to slide to the disengaging position to stop driving the sealing plate to rotate. In related technologies, fields, especially newly reclaimed fields, sometimes have large debris such as stones and residual plant roots in the shallow soil layer. When the seed tube rotates over this debris, it is blocked from penetrating the soil. Due to the large size of the debris, the seed tube cannot push it down. As a result, the seeded crop seeds remain on the surface of the soil above the debris, leading to shallow sowing. This makes the seeds susceptible to seedling loss due to dry topsoil or animal pecking. Furthermore, the presence of debris also hinders root development during germination. Under these circumstances, seeds cannot grow normally, resulting in a low germination rate. Sowing over debris is essentially a waste of crop seeds. To address this, in use, the seeding machinery of the present invention loads crop seeds into the internal space, and the traction device drives the connecting device to drag the wheel frame. After the seeding tube is inserted into the soil, the lever can be turned. At this time, the lever is connected to the connecting position, and the lever drives the sealing plate to rotate away from the seeding tube, thereby opening the opening of the seeding tube and allowing the crop seeds to be sown from the seeding tube into the soil. If there are large debris such as stones or residual plant roots in the soil surface, the end of the seeding tube will press against the debris, causing the seeding tube and the sealing plate to retract inward along the mounting opening into the internal space. At this time, the connecting part moves with the sealing plate, causing the part connected to the lever to slide from the connecting position to the disengaged position. At this time, turning the lever will not drive the sealing plate to open the seeding tube, thereby preventing the crop seeds from being sown in the debris area. After the seeding tube leaves the area where the debris is located, it can slide outward from the wheel body. At this time, the lever is reconnected to the connecting position to prepare for the next sowing.

[0010] As an optional technical solution, the connecting part is provided corresponding to the hinge axis between the sealing plate and the seeding tube. A sliding groove is provided on the connecting part; the sliding groove is an open groove that extends from the inside of the connecting part to the edge of the connecting part along the sliding direction of the seeding tube. The length of the sliding groove is less than or equal to the travel distance of the seeding tube relative to the mounting opening. The closed end of the sliding groove is the connecting position, and the open end is the disengaging position. When the seeding tube slides into the internal space against the debris, the lever also slides from the closed end to the open end relative to the sliding groove. Since the length of the sliding groove is less than or equal to the travel distance of the seeding tube relative to the mounting opening, the lever will disengage from the sliding groove, thus losing its driving ability on the sealing plate, allowing the sealing plate to maintain the seal on the seeding tube. After the seeding tube leaves the area where the debris is located, it can slide outwards from the wheel body. At this time, the lever slides back into the closed end from the open end of the sliding groove, restoring its driving ability on the sealing plate, in preparation for the next seeding.

[0011] As an optional technical solution, the lever rotation part, extension part, and actuating part are configured such that the rotation part is parallel or coaxial with the hinge axis between the seeding tube and the sealing plate, and is slidably connected to the connecting part along the extension direction of the sliding groove; the extension part is spaced apart from the side along the extension direction of the rotation part, with one end connected to the rotation part and the other end connected to the actuating part; the actuating part is parallel to the side and inclined towards the direction from the sealing plate to the seeding tube.

[0012] The wheel frame includes a toggle assembly, which is disposed corresponding to the toggle part. The toggle assembly is used to toggle the toggle part so that the rotating part drives the sealing plate to rotate relative to the seeding tube. The wheel rolls on the ground, and the seeding tubes distributed on the outer circumference are inserted into the soil in sequence. Since the wheel frame does not roll, when the wheel rotates, the toggle part of the lever will be toggled in sequence by the toggle assembly, thereby causing the rotating part to rotate to open the sealing plate and opening the outlet of the seeding tube in sequence. Thus, sowing is completed spontaneously as the wheel rolls forward, without the need for additional operation by the user.

[0013] As an optional technical solution, the lever further includes a slider, which is disposed on the rotating part and slidably connected to the sliding groove;

[0014] Starting from the connection point between the slider and the rotating part, the width of the slider towards the closed end of the sliding groove gradually decreases, and the length of the slider towards the open end of the sliding groove is greater than or equal to the distance between the axis of the rotating part along the tangential direction of the wheel body and the closed plate. When the seeding tube retracts into the internal space, the open end of the slider towards the sliding groove can overlap the closed plate to prevent the lever from rotating excessively. When the seeding tube extends outward from the wheel body, the gradually decreasing width of the slider towards the closed end of the sliding groove facilitates the slider's re-entry into the sliding groove.

[0015] As an optional technical solution, the seeding tube includes a back side that fits against and slidably connects to the mounting port. A connecting groove is provided on the back side, arranged along the sliding direction of the seeding tube. The distance between the end of the connecting groove near the mounting port and the internal space is less than the sliding stroke of the seeding tube, while the distance between the end of the connecting groove near the mounting port and the internal space is greater than the sliding stroke of the seeding tube. A marking chamber is provided in the internal space, with its opening corresponding to the connecting groove. The marking chamber is used to communicate with the connecting groove when the seeding tube slides into the internal space. A marker of a different color from the soil can be placed in the marking chamber. When the seeding tube retracts due to debris in the soil, the marking chamber connects with the connecting groove, and the marker in the marking chamber is transported to the debris location through the connecting groove to form a marker. This allows for manual identification of the debris and replanting at that location in subsequent processes.

[0016] As an optional technical solution, the connecting device includes:

[0017] A base, which is slidably disposed on the vehicle body and the sliding direction is parallel to the plane of rotation of the moving system;

[0018] Mounting bracket, which is hinged to the base, has a plane of rotation parallel to the plane of rotation of the moving system;

[0019] A connecting frame is included, with the connecting rod hinged to the mounting frame. An elastic component is provided at the hinge point between the connecting frame and the mounting frame, applying a torque to the connecting frame to rotate towards the moving system. By changing the angle between the mounting frame and the base, the proximity of the seeding wheel to the ground can be altered, thereby changing the pressure of the seeding wheel on the soil during sowing, and consequently, the sowing depth. The elastic component at the hinge point between the connecting frame and the mounting frame can compress or extend as the seeding wheel rolls over protrusions or depressions in the field, thus continuously supporting the seeding wheel.

[0020] As an optional technical solution, two mobile systems are provided, positioned on opposite sides of the vehicle body. Each mobile system includes a drive wheel, a track, and a support wheel. The drive wheel is rotatably connected to the vehicle body, and the support wheel is positioned corresponding to the drive wheel, spaced apart from the vehicle body. The track connects the drive wheel and the support wheel. Using the track improves the vehicle body's passability and enhances the reliability of the seeding machinery in field movement.

[0021] As an optional technical solution, a control device is also included, which is signal-connected to the mobile system and is used to control the mobile system.

[0022] As an optional technical solution, the control device is connected to the vehicle body or the connecting device.

[0023] One or more technical solutions provided by this invention have at least the following technical effects or advantages:

[0024] The seeding machinery of the present invention comprises a body and a moving system, and a seeding device. The seeding wheel of the seeding device is mounted on a wheel frame, which is connected to the body via a connecting device, which is rotatably connected to the body. In use, the seeding machinery is deployed in the field, the moving system contacts the ground, and the seeding wheel is filled with the crop seeds to be sown. During sowing, the moving system drives the body to move, and the seeding wheel rolls under the traction of the body, sowing the crop seeds in the field. Because the connecting device is rotatably connected to the body, the seeding wheel can contact the soil with relatively uniform pressure while rolling forward with the body, thereby stabilizing the sowing depth. Since the traction device replaces standardized wheeled tractors and other large agricultural implements, the size and weight are greatly reduced, the flexibility is improved, it is easy to move between different fields, and it can adapt to fields with irregular edges.

[0044] Example 1

[0045] This embodiment provides a seeding machine, including:

[0046] The traction device 1 includes a vehicle body 11 and a moving system 12. The moving system 12 is mounted on the vehicle body 11 and is used to at least partially rotate to drive the vehicle body 11 to move.

[0047] Connecting device 2 is rotatably connected to vehicle body 11, and the plane of rotation of connecting device 2 is parallel to the plane of rotation of moving device;

[0048] The sowing device 3 includes a sowing wheel 31 and a wheel frame 32. The wheel frame 32 is connected to the connecting device 2, and the sowing wheel 31 is rotatably connected to the wheel frame 32. In use, the sowing machinery is deployed in the field, the moving system 12 contacts the ground, and the sowing wheel 31 is filled with crop seeds. During sowing, the moving system 12 drives the vehicle body 11 to move, and the sowing wheel 31 rolls under the traction of the vehicle body 11, sowing the crop seeds in the field. Because the connecting device 2 is rotatably connected to the vehicle body 11, the sowing wheel 31 rolls forward with the vehicle body 11, allowing it to contact the soil with relatively uniform pressure, thus stabilizing the sowing depth. Since the traction device 1 replaces standardized wheeled tractors and other large agricultural implements, its size and weight are significantly reduced, its flexibility is improved, it is easy to move between different fields, and it can adapt to fields with irregular edges.

[0049] The mobile system 12 can have multiple pairs of tires, which are mounted in pairs and rotate on both sides of the vehicle body 11. The multiple pairs of tires are spaced apart along the length of the vehicle body 11. There can be two, three, or more pairs of tires.

[0050] Example 2

[0051] Based on Embodiment 1, the seeding wheel 31 includes a wheel body 311 and a seeding assembly. The wheel body 311 includes an outer peripheral surface 3111 and two side surfaces 3112. The two side surfaces 3112 are arranged opposite to each other and connected to the outer peripheral surface 3111. The two side surfaces 3112 and the outer peripheral surface 3111 enclose an internal space. The outer peripheral surface 3111 is provided with a plurality of mounting ports. The mounting ports extend from the outside of the outer peripheral surface 3111 to the internal space. The plurality of mounting ports are distributed circumferentially along the outer peripheral surface 3111.

[0052] The seeding assembly includes a seeding tube 41, a sealing plate 42, and a lever 5. The seeding tube 41 passes through the mounting opening and slides into it, connecting the internal space to the outside of the wheel body 311. The sealing plate 42 covers the opening of the seeding tube 41 on the side opposite to the wheel body 311 and is hinged to the side of the seeding tube 41 closest to the wheel body 311, with its hinge axis parallel to the rotation axis of the wheel body 311. A connecting part 421 is provided on the side of the sealing plate 42 closest to the wheel body 311, and the connecting part 421 has a sliding direction along the seeding tube 41. The connecting position 4211 and the disengaging position 4212 are provided, wherein the connecting position 4211 is closer to the wheel body 311 than the disengaging position 4212; the lever 5 is at least partially parallel or coaxial with the hinge axis between the seeding tube 41 and the sealing plate 42, and is slidably connected to the connecting part 421 in the direction from the connecting position 4211 to the disengaging position 4212. The lever 5 is used to connect the connecting position 4211 to drive the sealing plate 42 to rotate relative to the seeding tube 41, or slide to the disengaging position 4212 to stop driving the sealing plate 42 to rotate.

[0053] In related technologies, fields, especially newly reclaimed fields, sometimes have large debris such as stones and residual plant roots in the shallow soil layer. When the seed tube rotates over this debris, it is blocked from penetrating the soil. Due to the large size of the debris, the seed tube cannot push it down. As a result, the seeded crop seeds remain on the surface of the soil above the debris, leading to shallow sowing. This makes the seeds susceptible to seedling loss due to dry topsoil or animal pecking. Furthermore, the presence of debris also hinders root development during seed germination. Under these circumstances, seeds cannot grow normally, resulting in a low germination rate. Sowing with the seed reel 31 over debris is essentially a waste of crop seeds. In response to this, when the seeding machine of this embodiment is used, crop seeds are filled into the internal space, and the traction device 1 drives the connecting device 2 to drag the wheel frame 32. After the seeding tube 41 is inserted into the soil, the lever 5 can be turned. At this time, the lever 5 is connected to the connecting position 4211. The lever 5 drives the sealing plate 42 to rotate away from the seeding tube 41, thereby opening the opening of the seeding tube 41, so that the crop seeds can be sown from the seeding tube 41 into the soil. If there are large debris such as stones or residual plant roots in the soil surface, the end of the seeding tube 41 will press against the debris, causing the seeding tube 41 and the sealing plate 42 to retract into the internal space along the installation opening. At this time, the connecting part 421 and the sealing plate 42 move, so that the part of the connecting lever 5 slides from the connecting position 4211 to the disengagement position 4212. At this time, turning the lever 5 will not drive the sealing plate 42 to open the seeding tube 41, thereby preventing the crop seeds from being sown in the debris. After the seeding tube 41 leaves the area where the debris is located, in the state where the seeding tube 41 is retracted into the internal space, the weight of the crop seeds filled in the internal space can be used to push the seeding tube 41 out and slide it to the outside of the wheel body 311 to complete the reset. It can slide out to the outside of the wheel body 311. At this time, the lever 5 is reconnected to the connection position 4211 to prepare for the next seeding.

[0054] like Figure 6 As shown, in some embodiments, the connecting part 421 is a sheet-like structure with a groove along its thickness direction. The width of the groove near the wheel 311 is smaller than the width of the wheel 311. The side of the groove near the wheel 311 serves as the connecting position 4211, and the side away from the wheel 311 serves as the disengagement position 4212. The axial cross-section of the connection between the lever 5 and the connecting part 421 is rectangular, elliptical, or oblong, etc., with its diagonal length or major axis length being greater than the width of the groove at the connecting position 4211 and less than the width of the groove at the disengagement position 4212. Thus, the side of the groove near the wheel 311, i.e., the connecting position 4211, can engage with the connecting part 421 to drive the closing plate 42, while the side of the connecting part 421 away from the wheel 311, i.e., the disengagement position 4212, can rotate freely without causing the connecting part 421 and the closing plate 42 to rotate.

[0055] like Figure 7As shown, in some embodiments, the connecting part 421 is provided corresponding to the hinge shaft between the sealing plate 42 and the seeding tube 41. A sliding groove is provided on the connecting part 421. The sliding groove is an open groove that extends from the inside of the connecting part 421 to its edge along the sliding direction of the seeding tube 41. The length of the sliding groove is less than or equal to the travel distance of the seeding tube 41 relative to the mounting opening. The closed end of the sliding groove is the connecting position 4211, and the open end is the disengaging position 4212. When the seeding tube 41 slides into the interior space against debris, the lever 5 also slides from the closed end to the open end relative to the sliding groove. Since the length of the sliding groove is less than or equal to the travel distance of the seeding tube 41 relative to the mounting opening, the lever 5 will disengage from the sliding groove, thus losing its driving ability on the sealing plate 42, allowing the sealing plate 42 to remain closed to the seeding tube. After the seeding tube 41 leaves the area where the debris is located, it can slide out to the outside of the wheel body 311. At this time, the lever 5 slides back into the closed end from the open end of the sliding groove to restore the driving ability of the closed plate 42 in preparation for the next seeding.

[0056] As an optional implementation, the lever 5 has a rotating part 51, an extension part 52, and a toggle part 53. The rotating part 51 is arranged parallel or coaxially with the hinge axis between the seeding tube 41 and the sealing plate 42, and is slidably connected to the connecting part 421 along the extension direction of the sliding groove. The extension part 52 is spaced apart from the side surface 3112 along the extension direction of the rotating part 51. One end of the extension part 52 is connected to the rotating part 51, and the other end is connected to the toggle part 53. The toggle part 53 is arranged parallel to the side surface 3112 and is inclined toward the direction from the sealing plate 42 to the seeding tube 41.

[0057] The wheel frame 32 includes an actuating component 321, which is disposed corresponding to the actuating part 53. The actuating component 321 is used to actuate the actuating part 53 to drive the rotating part 51 to rotate the closing plate 42 relative to the seeding tube 41. The wheel body 311 rolls on the ground, and the seeding tubes 41 distributed on the outer peripheral surface 3111 are inserted into the soil in sequence. Since the wheel frame 32 does not roll, when the wheel body 311 rotates, the actuating part 53 of the lever 5 will be actuated in sequence by the actuating component 321, thereby causing the rotating part 51 to rotate to open the closing plate 42, so that the outlet of the seeding tube 41 opens in sequence. Thus, the seeding is completed spontaneously as the wheel body 311 rolls forward, without the need for additional operation by the user.

[0058] As an optional implementation, the lever 5 also includes a slider 54, which is disposed on the rotating part 51 and slidably connected to the sliding groove;

[0059] Starting from the connection point between slider 54 and rotating part 51, the width of slider 54 towards the closed end of the sliding groove gradually decreases, and the length of slider 54 towards the open end of the sliding groove is greater than or equal to the distance between the axis of rotating part 51 along the tangential direction of wheel body 311 and the closing plate 42. When the seeding tube 41 retracts into the internal space, the open end of slider 54 towards the sliding groove can overlap with the closing plate 42 to prevent the lever 5 from rotating excessively. When the seeding tube 41 extends outward from wheel body 311, the gradually decreasing width of slider 54 towards the closed end of the sliding groove facilitates slider 54 re-entering the sliding groove.

[0060] As an optional implementation, the seeding tube 41 includes a back surface 411, which is fitted to and slidably connected to the mounting port. A connecting groove 412 is provided on the back surface 411. The connecting groove 412 is arranged along the sliding direction of the seeding tube 41. The distance between the end of the connecting groove 412 near the mounting port and the internal space is less than the sliding stroke of the seeding tube 41, and the distance between the end of the connecting groove 412 near the mounting port and the internal space is greater than the sliding stroke of the seeding tube 41. A marking chamber 413 is provided in the internal space. The opening of the marking chamber 413 is set corresponding to the connecting groove 412. The marking chamber 413 is used to communicate with the connecting groove 412 when the seeding tube 41 slides into the internal space. The marking chamber 413 can be filled with markers such as fine sand or pigment that are different in color from the soil. When the seeding tube 41 retracts due to the debris in the soil, the marking chamber 413 is connected to the connecting channel 412. The markers in the marking chamber 413 are transported to the debris through the connecting channel 412 to form a mark. In subsequent processes, the debris can be identified manually and replanted at that location.

[0061] As an optional implementation, the connecting device 2 includes:

[0062] The base 21 is slidably disposed on the vehicle body 11, and the sliding direction is parallel to the rotation plane of the moving system 12;

[0063] Mounting bracket 22 is hinged to base 21, and its plane of rotation is parallel to the plane of rotation of moving system 12;

[0064] A connecting frame 23 is connected to a mounting frame 22 via a connecting rod. An elastic component 231 is provided at the hinge point between the connecting frame 23 and the mounting frame 22. The elastic component 231 applies a torque to the connecting frame 23 to rotate towards the moving system 12. By changing the angle between the mounting frame 22 and the base 21, the proximity of the seeding wheel 31 to the ground can be changed, thereby altering the pressure of the seeding wheel 31 on the soil during sowing and consequently changing the sowing depth. The elastic component 231 at the hinge point between the connecting frame 23 and the mounting frame 22 can compress or extend as the seeding wheel 31 rolls over protrusions or depressions in the field, thus continuously supporting the seeding wheel 31.

[0065] The elastic component 231 may include a spring and an adjusting screw. One end of the adjusting screw is hinged to the connecting frame 23, and the other end is slidably connected to the mounting frame 22. An adjusting nut is provided at the end of the adjusting screw on the side of the mounting frame 22 away from the connecting frame 23. The spring is sleeved on the adjusting screw, with one end abutting against the connecting frame 23 and the other end abutting against the mounting frame 22. The degree of compression of the spring can be changed by rotating the adjusting nut.

[0066] In addition, the elastic component 231 can also be an airbag, a leaf spring assembly, etc.

[0067] As an optional implementation, two mobile systems 12 are provided, positioned on opposite sides of the vehicle body 11. Each mobile system 12 includes a drive wheel 121, a track 122, and a support wheel 123.
