Description

Technical Field

[0001] The present invention relates to the technical field of corn planting, and particularly relates to a large-ridge single-row corn planting device and a method thereof. Background Art

[0002] Corn, also known as maize, corn cob, corn, pearl rice, etc., is an annual tall herbaceous plant of the genus Zea in the family Poaceae of the order Poales. In the southern regions with warm climates, corn can be planted in two crops, namely spring corn and autumn corn.

[0003] When planting corn currently, the corn straws remaining from the previous crop in the field are removed in advance. Since the roots of corn are relatively firm, it is laborious to remove them. Moreover, the number of corns in one row is relatively large, making the corn planting operation heavy. In addition, most of the removed corn straws are used as fuel or crushed to make fertilizer. However, when making fertilizer from corn straws currently, the corn straws need to be removed from the field, brought back, crushed by a crusher, and then the prepared fertilizer needs to be carried to the corn planting field for fertilization, which significantly increases the processing steps of corn straws and the workload of planting personnel. Therefore, a large-ridge single-row corn planting device and a method thereof are proposed to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the prior art, and a large-ridge single-row corn planting device and a method thereof are proposed.

[0005] To achieve the above purpose, the present invention adopts the following technical scheme:

[0006] The large-ridge single-row corn planting device includes a U-shaped moving frame for support and driving vehicles arranged at the bottom ends on both sides of the U-shaped moving frame. A pair of oppositely arranged lifting cylinders are installed at the top of the U-shaped moving frame. The output end of the lifting cylinder is fixedly connected with a connecting mounting plate. A crushing assembly for crushing corn straws is arranged on the connecting mounting plate. The bottom end of the connecting mounting plate is fixedly connected with a conical seat. The top end of the conical seat is of a planar structure. A traction opening is opened at the center of the top end of the conical seat. Symmetrical traction components are slidably arranged at the top end of the conical seat. A rotating outer ring plate is rotatably arranged at the side of the conical seat. A combing plate is fixedly connected to the inner wall of the rotating outer ring plate above the conical seat. A loosening inner gear ring is fixedly connected to the inner wall of the conical seat below the conical seat. A circular opening is opened at the bottom end of the conical seat near the side. A storage pipe is rotatably arranged inside the circular opening. The bottom end of the storage pipe is detachably connected with a sowing pipe.

[0007] A plurality of mounting seats are circumferentially distributed at the bottom end of the conical seat near the traction port. A soil loosening rod is rotatably arranged at the bottom end of the mounting seat. A driven gear is fixedly connected to the surface of the soil loosening rod near the top end. A hollow transmission column is rotatably arranged at the bottom end of the conical seat. A soil-breaking internal tooth ring meshing with the driven gear is fixedly connected to the inner wall of the hollow transmission column.

[0008] Preferably, the crushing assembly includes a crushing roller rotatably arranged between the connecting mounting plates. One-way gears meshing with each other are fixedly connected to one ends of the two crushing rollers. A crushing motor is connected to one end of one of the crushing rollers.

[0009] Preferably, the traction assembly includes a fixed block fixedly connected to the top end of the conical seat, a U-shaped block slidably arranged at the top end of the conical seat. A conveying roller is rotatably arranged inside the U-shaped block. A conveying motor for driving its rotation is arranged at one end of the conveying roller. Rubber protrusions with a reticulated pattern are arranged on the surface of the conveying roller to increase the friction between the conveying roller and the corn straw. A clamping spring is fixedly connected between the U-shaped block and the fixed block.

[0010] Preferably, a driving motor is installed near the side of the bottom end of the conical seat. A toothed edge transmission wheel meshing with the soil loosening internal tooth ring is fixedly connected to the output end of the driving motor. A transmission belt is connected between the toothed edge transmission wheel and the hollow transmission column.

[0011] Preferably, an external tooth ring meshing with the soil loosening internal tooth ring is fixedly connected to the surface of the storage pipe. A circumferentially distributed discharge port is opened on the side wall of the storage pipe. An inner sliding pipe is slidably arranged inside the storage pipe. A circumferentially distributed dislocation port is opened on the side wall of the inner sliding pipe.

[0012] Preferably, the bottom end of the inner sliding pipe is fixedly connected to a movable block through a connecting rod. A pressing cone is fixedly connected to the bottom end of the movable block. A sealing ring adapted to the movable block is fixedly connected to the inner wall of the sowing pipe.

[0013] Preferably, dragging plates are fixedly connected to the two side walls of the U-shaped moving frame near the bottom end. A conical rolling wheel is rotatably arranged at one end of the dragging plate. An earth covering roller is fixedly connected between the conical rolling wheels. Soil gathering inclined plates for gathering soil are fixedly connected to the two side walls of the U-shaped moving frame.

[0014] The method for single-row planting of corn in large ridges includes the following steps:

[0015] First step, plan the planting points: Mark the sowing points on the large ridges in advance so that the sowing points are located between adjacent corn straws. Ensure that when the sowing pipe is above the sowing point, the corn straw can be directly opposite to the traction port at the center of the conical seat. Then, drive the U-shaped moving frame to move by using a driving vehicle so that the U-shaped moving frame is erected above the large ridges and moves along the large ridges where corn is planted.

[0016] Step 2: Dig pits on the large ridge and sow corn kernels; use the driving vehicle to drive the U-shaped moving frame forward to the sowing point, control the lifting cylinder to work, so that the conical seat descends, thereby driving the sowing pipe to descend. The sowing pipe rotates at high speed under the driving of the driving motor and drills into the soil. During this process, the pressing cone will be squeezed upward, causing the movable block to move upward to open the bottom pipe orifice of the sowing pipe, so that the corn seeds pass through the gap between the pressing cone and the pipe orifice and fall into the soil pit, realizing the functions of automatic pit digging and sowing;

[0017] Step 3: Remove the residual corn straw and apply fertilizer: During the descent of the conical seat, the corn straw will pass through the traction port and extend between the conveying rollers. The conveying rollers are driven by the conveying motor to pull the corn straw upward. At the same time, the soil loosening rod will drill into the ground to loosen the roots of the corn straw, reducing the stability of the roots, so that the conveying rollers can convey the corn straw upward and realize the crushing of the corn straw under the action of the crushing roller. The crushed corn straw is gathered on the upper surface of the conical seat near the rotating outer ring plate under the action of the inclined surface of the conical seat. At the same time, pour a small amount of fertilizer on the upper surface of the conical seat. Under the rotation of the combing plate with the rotating outer ring plate, it can mix the fertilizer and the crushed corn straw and push the mixed fertilizer into the storage pipe. The fertilizer is discharged through the discharge port on the side wall of the storage pipe and falls around the corn planting area, realizing the functions of automatic removal of residual corn straw and fertilization;

[0018] Step 4: Reinforce the large ridge: During the movement of the device, the soil gathering inclined plate connected to the U-shaped moving frame gathers the soil scattered on both sides of the large ridge. At the same time, under the rolling action of the conical rolling wheel, the gathered soil can be shaped on both sides of the large ridge, realizing the function of reinforcing the large ridge.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. In this solution, by setting a driving motor, a toothed edge transmission wheel, a rotating outer ring plate, a storage pipe and a sowing pipe, the driving motor cooperates with the toothed edge transmission wheel and the soil loosening internal toothed ring to drive the storage pipe to rotate, and then drives the sowing pipe to rotate, so that the sowing pipe drills into the soil. During this process, the pressing cone is pressed upward and drives the movable block to move upward, so that the corn seeds inside the sowing pipe fall into the soil through the gap between the pressing cone and the bottom pipe orifice of the sowing pipe, realizing the functions of automatic pit digging and sowing.

[0021] 2. In this solution, by setting up a soil loosening rod, a crushing component, and a traction component, during the downward movement of the conical seat, the top of the corn straw passes through the traction opening and extends between the conveying rollers. At the same time, the high-speed rotating soil loosening rod drills into the soil to loosen the soil around the root of the corn straw, reducing the stability of the straw root, so that the traction component can pull the straw upward between the crushing rollers, realizing the removal and crushing functions of the residual corn straw on the large ridge.

[0022] 3. In this solution, by rotating the outer ring plate to drive the combing plate to rotate, it can mix the crushed corn straw and fertilizer, and push the mixed fertilizer into the storage pipe. When the sowing pipe is inserted into the soil, through the upward movement of the inner sliding pipe, the dislocation port and the discharge port are aligned, so that the fertilizer entering the storage pipe can be discharged through the discharge pipe and scattered around the corn planting area, realizing the automatic fertilization function for corn planting.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Example, see Figures 1 to 8 , a corn large ridge single row planting device, comprising a U-shaped mobile frame 1 that plays a supporting role and a driving vehicle 2 arranged at the bottom ends of both sides of the U-shaped mobile frame 1, and the driving vehicle 2 can drive the U-shaped mobile frame 1 to move along the large ridge direction;

[0037] At the top of the U-shaped moving frame 1, there are oppositely arranged lifting cylinders 3. The output end of the lifting cylinder 3 is fixedly connected with a connecting mounting plate. The lifting cylinder 3 drives the connecting mounting plate to lift, and then drives the conical seat 4 to lift, thereby controlling the lifting of the sowing pipe 10 so that the sowing pipe 10 can be inserted into the soil.

[0038] A crushing component for crushing corn straws is arranged on the connecting mounting plate. Further, the crushing component includes a crushing roller 7 rotatably arranged between the connecting mounting plates. One end of the two crushing rollers 7 is fixedly connected with a pair of meshing direction-changing gears. One end of one of the crushing rollers 7 is connected with a crushing motor 16.

[0039] It should be noted that: the crushing motor 16 cooperates with the direction-changing gears to drive the two crushing rollers 7 to rotate in opposite directions, realizing the crushing function of the upward-moving corn structure.

[0040] The bottom end of the connecting mounting plate is fixedly connected with a conical seat 4. The top end of the conical seat 4 is a planar structure. A traction opening is provided at the center of the top end of the conical seat 4. Symmetrical traction components are slidably arranged at the top end of the conical seat 4. Further, the traction components include fixed blocks 25 fixedly connected to the top end of the conical seat 4, U-shaped blocks slidably arranged at the top end of the conical seat 4, conveying rollers 8 rotatably arranged inside the U-shaped blocks. One end of the conveying roller 8 is provided with a conveying motor 15 for driving its rotation. The surface of the conveying roller 8 is provided with reticulated rubber protrusions for increasing the friction between the conveying roller 8 and the corn straws. A clamping spring 24 is fixedly connected between the U-shaped block and the fixed block 25.

[0041] It should be noted that: the conveying motor 15 drives the two conveying rollers 8 to rotate in opposite directions, and uses the friction between the conveying rollers 8 and the corn straws to realize the conveying function of upwardly conveying the corn straws;

[0042] It is worth noting that: the reticulated rubber protrusions on the surface of the conveying roller 8 can significantly increase the friction between the conveying roller 8 and the corn straws, ensuring that the conveying roller 8 has sufficient traction for the corn straws.

[0043] It is worth noting that: when the corn straw extends upward and contacts the conveying roller 8, it will push the conveying roller 8 to both sides. Under the guiding action of the arc surface of the conveying roller 8, the corn straw will have a pushing force on the two conveying rollers 8 on both sides, causing the two conveying rollers 8 to move to both sides and squeeze the clamping spring 24 through the U-shaped block. When the corn straw moves between the conveying rollers 8, under the elastic force of the clamping spring 24, the conveying roller 8 realizes the clamping function of the corn straw.

[0044] A rotary outer ring plate 5 is rotatably arranged on the side of the conical seat 4. An inner wall of the rotary outer ring plate 5 is fixedly connected with a carding plate 6 above the conical seat 4. The carding plate 6 can mix the fertilizer and crushed corn straw on the upper surface of the conical seat 4, and at the same time can push the mixed fertilizer and corn straw to the circular opening at the bottom end of the conical seat 4, so that the mixed fertilizer and corn straw enter the inside of the storage box;

[0045] An inner wall of the conical seat 4 is fixedly connected with a soil loosening inner gear ring 501 below the conical seat 4. A circular opening is formed at a position near the side of the bottom end of the conical seat 4. A storage pipe 18 is rotatably arranged inside the circular opening. A bottom end of the storage pipe 18 is detachably connected with a seeding pipe 10; Further, an outer gear ring 1801 meshing with the soil loosening inner gear ring 501 is fixedly connected to a surface of the storage pipe 18. A discharge port 1802 is formed in a side wall of the storage pipe 18 in a circumferential distribution. An inner sliding pipe 23 is slidably arranged inside the storage pipe 18. A dislocation port 2301 is formed in a side wall of the inner sliding pipe 23 in a circumferential distribution. Further, a bottom end of the inner sliding pipe 23 is fixedly connected with a movable block 20 through a connecting rod. A bottom end of the movable block 20 is fixedly connected with a pressing cone 21. A sealing ring 19 adapted to the movable block 20 is fixedly connected to an inner wall of the seeding pipe 10.

[0046] It should be noted that: the soil loosening inner gear ring 501 rotates under the driving action of the driving motor 26. The soil loosening inner gear ring 501 drives the outer gear ring 1801 to rotate. The outer gear ring 1801 drives the connected storage pipe 18 to rotate. The storage pipe 18 drives the seeding pipe 10 connected to its bottom end to rotate, so that the descending seeding pipe 10 can quickly drill into the soil. In this process, the pressing cone 21 first contacts the soil and retracts into the seeding pipe 10 under the extrusion of the soil, thereby driving the movable block 20 to move upward. When the movable block 20 moves upward, the pipe orifice at the bottom end of the seeding pipe 10 will be opened, so that the corn seeds below the sealing ring 19 inside the seeding pipe 10 fall into the soil through the gap between the pressing cone 21 and the pipe orifice, realizing the automatic seeding function;

[0047] It is worth noting that: when the movable block 20 moves upward, it will be combined with the central orifice of the sealing ring 19 to realize the sealing function of the sealing ring 19 and prevent too many corn seeds from entering the soil.

[0048] It should be noted that when the movable block 20 moves upward and combines with the central opening of the sealing ring 19, the inner sliding pipe 23 inside the storage pipe 18 moves upward, so that the dislocation opening 2301 on the side wall of the inner sliding pipe 23 aligns with the discharge opening 1802 on the side wall of the storage pipe 18. As a result, the mixed fertilizer and corn straw that enter the inside of the storage pipe 18 can be discharged through the discharge opening 1802, and under the action of the centrifugal force generated by the rotation of the storage pipe 18, the mixed fertilizer and corn straw are evenly spread around the corn planting points, avoiding the direct covering of the mixed fertilizer and corn straw above the soil at the planting site, and thus avoiding the phenomenon of burning seeds, realizing the automatic fertilization function.

[0049] A plurality of mounting seats 28 are circumferentially distributed at the bottom end of the conical seat 4 near the traction port. A soil loosening rod 9 is rotatably arranged at the bottom end of the mounting seat 28. A driven gear 22 is fixedly connected to the surface of the soil loosening rod 9 near the top end. A hollow transmission column 17 is rotatably arranged at the bottom end of the conical seat 4. A soil-breaking internal gear ring 1701 meshing with the driven gear 22 is fixedly connected to the inner wall of the hollow transmission column 17. Further, a driving motor 26 is installed at the bottom end of the conical seat 4 near the side. The output end of the driving motor 26 is fixedly connected to a toothed edge transmission wheel 27 meshing with the soil loosening internal gear ring 501. A transmission belt 14 is connected between the toothed edge transmission wheel 27 and the hollow transmission column 17.

[0050] It should be noted that the driving motor 26 drives the toothed edge transmission wheel 27 to rotate, thereby driving the soil loosening internal gear ring 501 to rotate. The soil loosening internal gear ring 501 drives the hollow transmission column 17 to rotate through the transmission belt 14. The hollow transmission column 17 drives the soil-breaking internal gear ring 1701 on its inner wall to rotate. The soil-breaking internal gear ring 1701 drives the driven gear 22 to rotate. The driven gear 22 drives the soil loosening rod 9 to rotate, so that the downward-moving soil loosening rod 9 drills into the soil, plays a role in loosening the soil at the root of the corn straw, reduces the stability of its root, and enables the conveying roller 8 to pull out the corn straw from the soil and convey it upward.

[0051] Further, dragging plates are fixedly connected to the two side walls of the U-shaped moving frame 1 near the bottom end. A conical rolling wheel 11 is rotatably arranged at one end of each dragging plate. An earth covering roller 12 is fixedly connected between the conical rolling wheels 11. Soil gathering inclined plates 13 for gathering soil are fixedly connected to the two side walls of the U-shaped moving frame 1.

[0052] It should be noted that during the movement of the U-shaped moving frame 1, the inclined soil gathering plates can gather the soil scattered on both sides of the large ridge, and then under the rolling action of the conical rolling wheels 11, the gathered soil can be shaped on both sides of the large ridge, playing a role in strengthening the large ridge.

[0053] Refer to Figure 9 , the single-row planting method for corn large ridges includes the following steps:

[0054] Step 1: Plan the planting points. Mark the sowing points on the large ridge in advance so that the sowing points are located between adjacent corn straws. Ensure that when the sowing tube 10 is above the sowing point, the corn straw can be directly opposite the traction opening at the center of the conical seat 4. Then, use the driving vehicle 2 to drive the U-shaped moving frame 1 to move, so that the U-shaped moving frame 1 is erected above the large ridge and moves along the large ridge where corn is planted;

[0055] Step 2: Dig pits on the large ridge and sow corn kernels. Use the driving vehicle 2 to drive the U-shaped moving frame 1 forward to the sowing point, control the lifting cylinder 3 to work, so that the conical seat 4 descends and drives the sowing tube 10 to descend. The sowing tube 10 rotates at high speed under the drive of the drive motor 26 and drills into the soil. During this process, the pressure cone 21 will be squeezed upward, so that the movable block 20 moves upward to open the bottom nozzle of the sowing tube 10, so that the corn seeds fall into the soil pit through the gap between the pressure cone 21 and the nozzle, realizing the functions of automatic pit digging and sowing;

[0056] Step 3: Remove the residual corn straw and apply fertilizer. During the descent of the conical seat 4, the corn straw will pass through the traction opening and extend between the conveying rollers 8. The conveying rollers 8 are driven by the conveying motor 15 to upwardly traction the corn straw. At the same time, the soil loosening rod 9 will drill into the ground to loosen the roots of the corn straw, reducing the stability of the roots, so that the conveying rollers 8 can convey the corn straw upward and realize the crushing of the corn straw under the action of the crushing roller 7. The crushed corn straw is gathered on the upper surface of the conical seat 4 near the position of the rotating outer ring plate 5 under the action of the inclined surface of the conical seat 4. At the same time, pour a small amount of fertilizer on the upper surface of the conical seat 4. Under the rotation of the combing plate 6 with the rotating outer ring plate 5, it can mix the fertilizer and the crushed corn straw and push the mixed fertilizer into the storage tube 18, so that the fertilizer is discharged through the discharge port 1802 on the side wall of the storage tube 18 and falls around the corn planting area, realizing the functions of automatic removal of residual corn straw and fertilization;

[0057] Step 4: Strengthen the large ridge. During the movement of the device, the soil gathering inclined plate 13 connected to the U-shaped moving frame 1 gathers the soil scattered on both sides of the large ridge. At the same time, under the rolling action of the conical rolling wheel 11, the gathered soil can be shaped on both sides of the large ridge, realizing the function of strengthening the large ridge.

[0058] When the present invention is used, mark the sowing points on the large ridge in advance so that the sowing points are located between adjacent corn straws. Ensure that when the sowing tube 10 is above the sowing point, the corn straw can be directly opposite the traction opening at the center of the conical seat 4. Use the driving vehicle 2 to drive the U-shaped moving frame 1 to move, so that the U-shaped moving frame 1 is erected above the large ridge and moves along the large ridge where corn is planted;

[0059] When the seeding tube 10 moves above the seeding point, the corn straw is directly opposite the traction port. At this time, the lifting cylinder 3 is activated, and at the same time, the driving motor 26, the crushing motor 16, and the conveying motor 15 are activated, causing the crushing roller 7 and the conveying roller 8 to rotate. The lifting cylinder 3 drives the connecting mounting plate to move downward, and further drives the conical seat 4 at the bottom of the connecting mounting plate to move downward. The conical seat 4 drives the soil loosening rod 9 and the seeding tube 10 to move downward;

[0060] When the driving motor 26 operates, it drives the toothed edge transmission wheel 27 at its conveying end to rotate. The toothed edge transmission wheel 27 drives the internal toothed loosening ring 501 to rotate. The internal toothed loosening ring 501 drives the external toothed ring 1801 to rotate. The external toothed ring 1801 drives the storage tube 18 to rotate. The storage tube 18 drives the seeding tube 10 connected to its bottom end to rotate, so that when the seeding tube 10 contacts the soil, it can quickly drill into the soil to achieve the function of automatic pit digging. During this process, the pressure cone 21 first contacts the soil and retracts into the seeding tube 10 under the extrusion of the soil, and then drives the movable block 20 to move upward. The upward movement of the movable block 20 will open the nozzle at the bottom of the seeding tube 10, so that the corn seeds below the sealing ring 19 inside the seeding tube 10 fall into the soil through the gap between the pressure cone 21 and the nozzle, achieving the function of automatic seeding;

[0061] When the soil loosening rod 9 contacts the soil, since the toothed edge transmission wheel 27 drives the transmission belt 14 to rotate, the transmission belt 14 drives the hollow transmission column 17 to rotate. The hollow transmission column 17 drives the internal toothed soil-breaking ring 1701 on its inner wall to rotate. The internal toothed soil-breaking ring 1701 drives the driven gear 22 on the surface of the soil loosening rod 9 to rotate, and further drives the soil loosening rod 9 to rotate quickly, so that the soil loosening rod 9 can quickly drill into the soil to loosen the soil at the root of the corn straw, reducing the stability of the root of the corn straw and facilitating the traction assembly to pull out the corn straw from the soil;

[0062] When the corn straw extends through the traction port to between the conveying rollers 8, under the frictional force between the conveying rollers 8 and the corn straw, the effect of upward conveying of the corn straw is achieved. When the corn straw contacts the crushing roller 7, under the action of the crushing roller 7, the crushing function of the corn straw is realized. The crushed corn straw is gathered on the upper surface of the conical seat 4 near the position of the rotating outer ring plate 5 under the action of the inclined surface of the conical seat 4. At the same time, a small amount of fertilizer is poured on the upper surface of the conical seat 4 near the position of the rotating outer ring plate 5. Under the rotation of the combing plate 6 following the rotating outer ring plate 5, the fertilizer and the crushed corn straw can be mixed, and at the same time, the mixed fertilizer and the crushed corn straw are pushed to the circular opening at the bottom end of the conical seat 4, so that the mixed fertilizer and the crushed corn straw enter the inside of the storage pipe 18. When the moving block 20 moves upward and combines with the central opening of the sealing ring 19, the inner sliding pipe 23 inside the storage pipe 18 moves upward, so that the misaligned opening 2301 on the side wall of the inner sliding pipe 23 is aligned with the discharge port 1802 on the side wall of the storage pipe 18, enabling the mixed fertilizer and corn straw that enter the inside of the storage pipe 18 to be discharged through the discharge port 1802, and under the action of the centrifugal force generated by the rotation of the storage pipe 18, the mixed fertilizer and corn straw are evenly scattered around the corn planting area, avoiding the direct covering of the mixed fertilizer and corn straw above the soil at the planting area, and thus avoiding the phenomenon of burning seeds; enabling the realization of the functions of automatically removing corn straw and automatically fertilizing corn seeds;

[0063] After that, control the lifting cylinder 3 to work, so that the conical seat 4 returns to its original position, thereby driving the soil loosening rod 9 and the sowing pipe 10 to return to their original positions. Then drive the driving vehicle 2 again to drive the U-shaped moving frame 1 to move, so that the sowing pipe 10 moves to the next sowing point for sowing operation;

[0064] During the movement of the U-shaped moving frame 1, the soil gathering inclined plate 13 connected to the U-shaped moving frame 1 gathers the soil scattered on both sides of the large ridge.
