A motor and a reduction gearbox are located on one side of the machine casing. A sowing disc is mounted on the output shaft of the reduction gearbox and is located inside the sowing chamber of the machine casing. An end cover is installed at the outer port of the sowing chamber, and the end cover has a feeding channel communicating with the sowing chamber. Multiple elastic finger clips that can automatically reset are evenly embedded and hinged along the circumferential direction of the edge of the sowing disc. A permanent magnet is inlaid on the finger clip near the outer edge of the seeding tray. A semi-circular top block is fixed inside the seeding chamber of the machine housing, corresponding to the inner side of the elastic finger clip.

The front of the protrusion on the inner side of the semi-circular top block is a slope. The semi-circular top block is located in the lower half of the seeding chamber. A Hall device is inlaid on the machine housing at the position of the screw-in end of the elastic finger clip corresponding to the semi-circular top block. The Hall device has two detection points, namely the first detection point and the second detection point.

[0004] In this prior art, since the maximum opening angle of the elastic finger clip cannot be adjusted, it cannot be adapted to seeds of different sizes (diameters), thus reducing the applicability of the product. Utility Model Content

[0005] To address the problem in existing technologies where the maximum opening angle of the elastic finger clamps cannot be adjusted, thus limiting their adaptability to different seed sizes and reducing product applicability, this invention provides a corn planting device.

[0010] In the above technical solution, the adjustment mechanism also includes: a feeding plate, an anti-jamming part, and a handle; the feeding plate is installed on the side of the pressing plate near the support wheel, and the feeding plate is located on the side of the opening and closing plate, and the feeding plate is located above the discharge port; the anti-jamming part is wavy and is set on the side of the feeding plate near the support wheel; the handle is connected to the second rotating shaft and is located on the outside of the housing.

[0011] In the above technical solution, the corn planting device further includes: a clamping part; the clamping part is disposed on the inner wall of the groove, and the clamping part is opposite to the finger clamp.

[0012] In the above technical solution, the corn planting device further includes: a driving cavity, a driving device, a first bevel gear, and a second bevel gear; the driving cavity is disposed inside the housing, the driving cavity is located between two receiving cavities, and at least part of the main shaft is located inside the driving cavity; the driving device is provided with a driving shaft, the driving device is installed on the outside of the housing, and the driving shaft is located inside the driving cavity; the first bevel gear is fitted on the outside of the main shaft, and the first bevel gear is located inside the driving cavity; the second bevel gear is connected to the driving shaft of the driving device, and the second bevel gear meshes with the first bevel gear.

[0014] The advantages of this corn planting device compared with the prior art are as follows:

[0015] 1. By rotatably connecting multiple first rotating shafts to the turntable assembly, connecting the finger clip to the first rotating shaft, and mounting the support wheel on the outer side of the first rotating shaft near the centerline of the turntable assembly, the turntable assembly can drive the first rotating shaft, finger clip, and support wheel to rotate within the receiving cavity. Simultaneously, the finger clip, first rotating shaft, and support wheel can rotate synchronously within the turntable assembly. By simultaneously abutting the pressure plate against multiple support wheels, installing the adjustment mechanism within the receiving cavity, and connecting the adjustment mechanism to the pressure plate, the adjustment mechanism can drive the pressure plate to move. This allows the pressure plate to press the support wheel and first rotating shaft to rotate, causing the finger clip to rotate within the groove. This adjusts the opening size between the finger clip and the turntable assembly, thereby adjusting the maximum opening angle of the finger clip to accommodate seeds of different sizes (diameters) and improve the product's applicability.

[0016] 2. By connecting the arc-shaped connecting plate to the pressure plate, the connecting groove is inclinedly set on the inner wall of the connecting plate, and at least part of the arc-shaped rack is embedded in the connecting groove, so that when the gear meshes and drives the arc-shaped rack to rotate, the arc-shaped gear drives the connecting plate and the pressure plate to move through the connecting groove, thereby enabling the pressure plate to press the support wheel and the first rotating shaft to rotate, so as to adjust the size of the opening between the finger clamp and the turntable assembly.

[0017] 3. By setting a trapezoidal adjustment groove inside the opening and closing plate, when the turntable assembly drives the support wheel to rotate to the adjustment groove, the support wheel does not contact the opening and closing plate. At this time, the torsion spring resets and drives the first rotating shaft and the finger clamp to rotate, thereby enabling the finger clamp to clamp the seed. When the support wheel moves out of the adjustment groove, the support wheel is in contact with the opening and closing plate again, thereby pressing the support wheel, the first rotating shaft and the finger clamp to rotate, so that the finger clamp is in the maximum opening and closing state. This ensures that the finger clamp can grasp the seed when the turntable assembly drives the finger clamp to rotate, thereby improving the efficiency of the finger clamp in picking up seeds.

[0018] 4. By setting the wavy anti-jamming part on the side of the feeding plate near the support wheel, the support wheel can move along the anti-jamming part. This allows the support wheel and the finger clamp to vibrate during movement, preventing seeds from sticking to the finger clamp and ensuring that the seeds can be discharged through the discharge port, thereby improving the user experience of the product.

[0019] 5. By setting the clamping part on the inner wall of the groove and making the clamping part opposite to the finger clip, the finger clip and the clamping part cooperate to clamp the seed, thereby improving the clamping effect on the seed and improving the user experience of the product.

[0020] 6. By fitting the first bevel gear onto the outside of the main shaft and engaging it with the second bevel gear, when the drive device drives the second bevel gear to rotate, the second bevel gear can engage the first bevel gear and the main shaft to rotate, thereby providing power for rotating the main shaft.

[0021] 7. By fastening the cover plate to the other end of the feed cylinder, the cover plate can be used to close the feed cylinder, thereby preventing foreign matter from entering the housing through the feed cylinder and the feed port; by connecting one end of the discharge cylinder to two discharge ports at the same time, the discharge cylinder can guide the seeds discharged through the discharge ports to ensure that the seeds can be sown to the predetermined position, further improving the user experience of the product.

Detailed Implementation

[0030] The following are specific implementation cases and appendices. Figures 1 to 6 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0031] A corn planting device, such as Figures 1 to 6As shown, the corn planting device includes: a shell 10, a receiving cavity 11, a feed inlet 12, a discharge outlet 13, partitions, a main shaft 15, a turntable assembly 16, a first rotating shaft 18, a finger clamp 19, a support wheel 20, a pressing plate 21, and an adjusting mechanism 22; the two receiving cavities 11 are respectively located on both sides of the shell 10; the feed inlet 12 is located at the top of one side of the shell 10, and the feed inlet 12 is simultaneously connected to both receiving cavities 11; the two discharge outlets 13 are located at the bottom of the other side of the shell 10, and the two discharge outlets 13 are respectively connected to the two receiving cavities 11; the two partitions are respectively located inside the bottom of the two receiving cavities 11, and the two partitions are respectively connected to the two inner walls of the shell 10, and the partitions are located between the feed inlet 12 and the discharge outlet 13; the main shaft 15 passes through the two side walls of the shell 10 in sequence, and the main shaft... 15 is rotatably connected to the housing 10; multiple grooves 17 are provided circumferentially for the turntable assembly 16, and the two turntable assemblies 16 are respectively embedded in the two receiving cavities 11, and the two turntable assemblies 16 are simultaneously connected to the main shaft 15; multiple first rotating shafts 18 are installed in the turntable assembly 16, and the first rotating shafts 18 are rotatably connected to the turntable assembly 16; finger clips 19 are located in the grooves 17, and the finger clips 19 are connected to the first rotating shafts 18; multiple support wheels 20 are respectively fitted on the outer side of the multiple first rotating shafts 18 near the center line of the turntable assembly 16; two pressure plates 21 are respectively located in the two turntable assemblies 16, and the pressure plates 21 are simultaneously in contact with the multiple support wheels 20; two adjustment mechanisms 22 are respectively installed in the two receiving cavities 11, and the two adjustment mechanisms 22 are respectively connected to the two pressure plates 21.

[0032] By setting two receiving cavities 11 on both sides of the housing 10, and setting the inlet 12 on the top of one side of the housing 10, and connecting the inlet 12 to both receiving cavities 11, two receiving spaces are created inside the housing 10, allowing workers to pour seeds into the two receiving cavities 11 through the inlet 12. By setting two outlets 13 at the bottom of the other side of the housing 10, and connecting the two outlets 13 to the two receiving cavities 11 respectively, and connecting two partitions to the two inner walls of the housing 10, with the partitions positioned between the inlet 12 and the outlet 13, seeds in the receiving cavities 11 can be discharged through the outlets 13. At the same time, the partitions separate the outlets 13 from the inlet 12, preventing seeds entering the receiving cavities 11 through the inlet 12 from being directly discharged through the outlets 13. By passing the main shaft 15 through the two side walls of the housing 10 in sequence and rotatably connecting the main shaft 15 to the housing 10, the housing 10 supports the rotating shaft, thereby enabling the main shaft 15 to rotate within the housing 10. By embedding the two turntable assemblies 16 into the two receiving cavities 11 respectively and connecting the two turntable assemblies 16 to the main shaft 15 simultaneously, the main shaft 15 can drive the two turntable assemblies 16 to rotate within the two receiving cavities 11. By installing multiple first rotating shafts 18 inside the turntable assembly 16 and rotatably connecting the first rotating shafts 18 to the turntable assembly 16, the turntable assembly 16 can support the multiple first rotating shafts 18, thereby enabling the first rotating shafts 18 to rotate within the turntable assembly 16. By placing the finger clip 19 inside the groove 17, connecting the finger clip 19 to the first rotating shaft 18, and respectively fitting multiple support wheels 20 onto the outer side of the multiple first rotating shafts 18 near the centerline of the turntable assembly 16, the first rotating shafts 18 can drive the finger clip 19 and the support wheels 20 to rotate, thereby adjusting the size of the opening between the finger clip 19 and the turntable assembly 16. By installing the adjustment mechanism 22 inside the receiving cavity 11, connecting the adjustment mechanism 22 to the pressing plate 21, and making the pressing plate 21 have multiple support wheels 20 in contact with each other, the adjustment mechanism 22 can drive the pressing plate 21 to move, thereby enabling the pressing plate 21 to press the support wheels 20 and the first rotating shaft 18 to rotate, thereby adjusting the size of the opening between the finger clip 19 and the turntable assembly 16 to accommodate seeds of different specifications (diameters).

[0033] Using the above structure, by rotatably connecting multiple first rotating shafts 18 to the turntable assembly 16, connecting the finger clip 19 to the first rotating shaft 18, and mounting the support wheel 20 on the outer side of the first rotating shaft 18 near the centerline of the turntable assembly 16, the turntable assembly 16 can drive the first rotating shaft 18, finger clip 19, and support wheel 20 to rotate within the receiving cavity 11. Simultaneously, the finger clip 19, first rotating shaft 18, and support wheel 20 can also rotate synchronously within the turntable assembly 16. By simultaneously connecting the pressure plate 21 to multiple supports... The support wheel 20 is fitted together, and the adjustment mechanism 22 is installed in the receiving cavity 11. The adjustment mechanism 22 is connected to the pressing plate 21 so that the adjustment mechanism 22 can drive the pressing plate 21 to move, thereby enabling the pressing plate 21 to press the support wheel 20 and the first rotating shaft 18 to rotate, so that the finger clip 19 rotates in the groove 17, thereby adjusting the size of the opening between the finger clip 19 and the turntable assembly 16, so as to adjust the maximum opening angle of the finger clip 19 to adapt to seeds of different specifications (diameters) and improve the applicability of the product.

[0034] In embodiments of this utility model, such as Figures 1 to 6 As shown, the adjusting mechanism 22 includes: a second rotating shaft 221, a gear 222, an arc-shaped rack 223, a connecting plate 224, and a connecting groove 225; the second rotating shaft 221 passes through one side wall of the housing 10, the second rotating shaft 221 is rotatably connected to the housing 10, and one end of the second rotating shaft 221 is embedded in the pressure plate 21; the gear 222 is located in the receiving cavity 11, and the gear 222 is fitted on the outside of the second rotating shaft 221; the arc-shaped rack 223 is arc-shaped. The arc-shaped rack 223 is wound around the outside of the gear 222 and meshes with the gear 222; the connecting plate 224 is arc-shaped and is placed on the pressure plate 21, and the connecting plate 224 is connected to the pressure plate 21, and the arc-shaped rack 223 is in contact with the inner wall of the connecting plate 224; the connecting groove 225 is inclinedly arranged on the inner wall of the connecting plate 224, and at least part of the arc-shaped rack 223 is embedded in the connecting groove 225.

[0035] By passing the second rotating shaft 221 through one side wall of the housing 10, the second rotating shaft 221 is rotatably connected to the housing 10, and one end of the second rotating shaft 221 is embedded in the pressure plate 21. This allows the housing 10 to support the second rotating shaft 221, enabling the second rotating shaft 221 to rotate within the housing 10. Simultaneously, the second rotating shaft 221 also limits the movement of the pressure plate 21, ensuring that the pressure plate 21 can only move along the axis of the second rotating shaft 221, thus preventing the pressure plate 21 from rotating and ensuring that the pressure plate 21 can press against the support wheel 20. Furthermore, by mounting the gear 222 on the outside of the second rotating shaft 221, and wrapping the arc-shaped rack 223 around the outside of the gear 222, the arc-shaped rack 223... 23 meshes with gear 222 so that the second rotating shaft 221 can drive gear 222 to rotate, thereby enabling gear 222 to mesh and drive the arc rack 223 to rotate; by connecting the arc-shaped connecting plate 224 to the pressure plate 21, the connecting groove 225 is inclinedly set on the inner wall of the connecting plate 224, and at least part of the arc rack 223 is embedded in the connecting groove 225, so that when gear 222 meshes and drives the arc rack 223 to rotate, the arc gear 222 drives the connecting plate 224 and the pressure plate 21 to move through the connecting groove 225, thereby enabling the pressure plate 21 to press the support wheel 20 and the first rotating shaft 18 to rotate, so as to adjust the size of the opening between the finger clip 19 and the turntable assembly 16.

[0036] In embodiments of this utility model, such as Figures 1 to 6 As shown, the adjustment mechanism 22 further includes: a torsion spring, an opening and closing plate 226, an adjustment groove 227, and a closing surface 228; the torsion spring is fitted on the outside of the first rotating shaft 18, one end of the torsion spring is connected to the first rotating shaft 18, and the other end of the torsion spring is connected to the turntable assembly 16; the opening and closing plate 226 is connected to the connecting plate 224, the opening and closing plate 226 passes through the pressure plate 21, and the opening and closing plate 226 is opposite to the support wheel 20; the adjustment groove 227 is trapezoidal and is disposed inside the opening and closing plate 226; the closing surface 228 is inclined and is disposed at the end of the opening and closing plate 226 away from the discharge port 13.

[0037] By fitting a torsion spring onto the outside of the first rotating shaft 18, connecting one end of the torsion spring to the first rotating shaft 18, and connecting the other end of the torsion spring to the turntable assembly 16, the turntable assembly 16 supports the first rotating shaft 18 through the torsion spring, thereby ensuring that the first rotating shaft 18 can be reset. By connecting the opening and closing plate 226 to the connecting plate 224, the opening and closing plate 226 passes through the pressure plate 21 and is opposite to the support wheel 20, so that when the turntable assembly 16 drives the support wheel 20 to rotate to the opening and closing plate 226, the opening and closing plate 226 is in contact with the support wheel 20, thereby pressing the support wheel 20, the first rotating shaft 18, and the finger clip 19 to rotate, so that the finger clip 19 is in the maximum open and closed state, so that the seed can be embedded in the finger clip 19, thereby enabling the finger clip 19 to hold the seed and drive the seed to rotate, so as to complete the single seed picking. By setting the trapezoidal adjustment groove 227 inside the opening and closing plate 226, when the turntable assembly 16 drives the support wheel 20 to rotate to the adjustment groove 227, the support wheel 20 does not contact the opening and closing plate 226. At this time, the torsion spring resets and drives the first rotating shaft 18 and the finger clamp 19 to rotate, thereby enabling the finger clamp 19 to clamp the seed. When the support wheel 20 moves out of the adjustment groove 227, the support wheel 20 is again in contact with the opening and closing plate 226, thereby pressing the support wheel 20, the first rotating shaft 18 and the finger clamp 19 to rotate, so that the finger clamp 19 is in the maximum opening and closing state. This ensures that the finger clamp 19 can grip the seed when the turntable assembly 16 drives the finger clamp 19 to rotate, thereby improving the seed picking efficiency of the finger clamp 19. By setting the inclined closed surface 228 at one end of the opening and closing plate 226 away from the discharge port 13, the support wheel 20 can move along the closed surface 228, so that the support wheel 20 gradually stops contacting the opening and closing plate 226, so that the torsion spring is reset and drives the first rotating shaft 18 to rotate, thereby ensuring that the finger clamp 19 clamps the seed.

[0038] In embodiments of this utility model, such as Figures 1 to 6 As shown, the adjustment mechanism 22 also includes: a feeding plate 229, an anti-jamming part 230, and a handle 231; the feeding plate 229 is installed on the side of the pressing plate 21 near the support wheel 20, and the feeding plate 229 is located on one side of the opening and closing plate 226, and the feeding plate 229 is located above the discharge port 13; the anti-jamming part 230 is wavy and is provided on the side of the feeding plate 229 near the support wheel 20; the handle 231 is connected to the second rotating shaft 221, and the handle 231 is located on the outside of the housing 10.

[0039] By mounting the feeding plate 229 on the side of the pressing plate 21 near the support wheel 20 and positioning the feeding plate 229 above the discharge port 13, when the turntable assembly 16 drives the support wheel 20 to rotate above the discharge port 13, the support wheel 20 contacts the feeding plate 229, thereby causing the feeding plate 229 to press the support wheel 20 and the first rotating shaft 18 to rotate, thus opening the finger clip 19 and ensuring that seeds can enter the discharge port 13 to complete the sowing. By setting the wavy anti-jamming part 230 on the side of the feeding plate 229 near the support wheel 20, the support wheel 20 can move along the anti-jamming part 230, thereby causing the support wheel 20 and the finger clip 19 to vibrate during movement, preventing seeds from sticking to the finger clip 19 and ensuring that seeds can be discharged through the discharge port, thus improving the user experience of the product. By connecting the handle 231 to the second rotating shaft 221 and positioning the handle 231 on the outside of the housing 10, the operator can rotate the second rotating shaft 221 from the outside of the housing 10 via the handle 231, thereby reducing the difficulty of rotating the second rotating shaft 221 and improving the user experience of the product.

[0040] In embodiments of this utility model, such as Figures 1 to 6 As shown, the corn planting device also includes a clamping part 24; the clamping part 24 is disposed on the inner wall of the groove 17, and the clamping part 24 is opposite to the finger clamp 19.

[0041] By setting the clamping part 24 on the inner wall of the groove 17 and making the clamping part 24 opposite to the finger clip 19, the finger clip 19 and the clamping part 24 cooperate to clamp the seeds, thereby improving the clamping effect on the seeds and enhancing the user experience of the product.

[0043] By placing the drive cavity 25 inside the housing 10, positioning the drive cavity 25 between the two receiving cavities 11, and placing at least a portion of the main shaft 15 within the drive cavity 25, the main shaft 15 can rotate within the drive cavity 25. By mounting the drive device 26 outside the housing 10, positioning the drive shaft of the drive device 26 within the drive cavity 25, and connecting the second bevel gear 28 to the drive shaft of the drive device 26, the drive device 26 can drive the second bevel gear 28 to rotate within the drive cavity 25 via the drive shaft. By sleeved the first bevel gear 27 on the outside of the main shaft 15 and meshing the first bevel gear 27 with the second bevel gear 28, when the drive device 26 drives the second bevel gear 28 to rotate, the second bevel gear 28 can mesh with the first bevel gear 27 and rotate the main shaft 15, thereby providing power for rotating the main shaft 15.

By fastening the cover plate 30 to the other end of the feed cylinder 29, the cover plate 30 can close the feed cylinder 29, thereby preventing debris from entering the housing 10 through the feed cylinder 29 and the feed inlet 12. By connecting one end of the discharge cylinder 31 to two discharge ports 13 at the same time, the discharge cylinder 31 can guide the seeds discharged through the discharge ports 13 to ensure that the seeds can be sown to the predetermined position, further improving the user experience of the product.

[0046] The specific usage process of this product is as follows:

[0047] First, the second rotating shaft 221 is rotated by the handle 231, so that the second rotating shaft 221 meshes with the arc-shaped rack 223 through the gear 222, causing the arc-shaped rack 223 to press the connecting plate 224 and the pressing plate 21 through the connecting groove 225, thereby causing the pressing plate 21 to press the support wheel 20 and the first rotating shaft 18 through the opening and closing plate 226 to rotate within the turntable assembly 16, so as to adjust the maximum opening and closing angle between the finger clip 19 and the pressing part to accommodate seeds of different specifications; then, the cover plate 30 is opened and the seeds are poured into the feed cylinder 29, so that the seeds enter the receiving cavity 11 and are pushed and accumulated at the lowest point of the receiving cavity 11 (the seed accumulation position is located below the opening and closing plate 226); then, the drive device 26 is started. The drive device 26 drives the main shaft 15 to rotate via the first bevel gear 27 and the second bevel gear 28, thereby causing the main shaft 15 to drive the two turntable assemblies 16 to rotate in the two receiving cavities 11 respectively. When the turntable assembly 16 rotates in the receiving cavity 11, it will drive the first rotating shaft 18, the finger clip 19, and the support wheel 20 to rotate in the receiving cavity 11. When the support wheel 20 moves to the opening and closing plate 226, the opening and closing plate 226 will press the support wheel 20 and the first rotating shaft 18 to rotate in the turntable assembly 16, thereby putting the finger clip 19 at its maximum opening and closing angle so that the seed can enter between the finger clip 19 and the clamping part 24. At this time, the torsion spring is in a compressed state. Then, the turntable assembly 16 will continue to drive the first rotating shaft 18, the support wheel 19, and the support wheel 20 to rotate in the receiving cavity 11. The wheel 20 and finger clip 19 rotate, causing the support wheel 20 to move to the adjustment groove 227. The support wheel 20 is not in contact with the opening and closing plate 226. At this time, the torsion spring resets and drives the first rotation, thereby clamping the finger clip 19 onto the seed. Then, the turntable assembly 16 continues to drive the first rotating shaft 18, support wheel 20, and finger clip 19 to rotate, causing the support wheel 20 to move out of the adjustment groove 227, thereby making the support wheel 20 in contact with the opening and closing plate 226, pressing the support wheel 20, the first rotating shaft 18, and the finger clip 19 to rotate, so that the finger clip 19 is in the maximum opening and closing state. This ensures that when the turntable assembly 16 drives the finger clip 19 to rotate, any excess seeds (more than one) between the finger clip 19 and the turntable assembly 16 can be removed, ensuring the finger clip 19 can be clamped onto the seed. The clamp 19 and the turntable assembly 16 can only hold one seed at a time. Then, the turntable assembly 16 continues to drive the first rotating shaft 18, the support wheel 20, and the finger clamp 19 to rotate, thereby disengaging the support wheel 20 from the opening and closing plate 226. At this time, the torsion spring resets and drives the first rotating shaft 18 to rotate, thereby causing the finger clamp 19 to clamp the seed to improve the stability of the seed. Then, the turntable assembly 16 continues to rotate. When the support wheel 20 moves to the feeding plate 229, the support wheel 20 contacts the feeding plate 229, thereby causing the feeding plate 229 to press the support wheel 20 and the first rotating shaft 18 to rotate, thereby causing the finger clamp 19 to open, so that the seed clamped by the finger clamp 19 can be discharged sequentially through the discharge port 13 and the discharge cylinder 31 to complete the sowing of the seed.
