Description

Technical Field

[0001] This invention relates to the field of agricultural planting machinery technology, specifically to a planting machine that is adaptable to various cassava seedling planting methods. Background Technology

[0002] Cassava cultivation mainly relies on asexual reproduction of seed tubers. In agronomic production, to adapt to different soil conditions, climate environments, and cultivation management needs, four mainstream planting methods have emerged: flat planting on ridges, direct planting on ridges, slanted planting on ridges, and slanted planting on the middle of ridges. Different planting methods directly affect the cassava seedling emergence rate, tuber uniformity, lodging resistance, and the convenience of mechanized harvesting in the later stages. Among them, flat planting on ridges is conducive to seed germination and uniform seedling emergence; direct planting on ridges results in deep root development and strong wind and lodging resistance; slanted planting on ridges leads to rapid seedling emergence, concentrated tuber distribution, and convenient later harvesting; and slanted planting on the middle of ridges is suitable for planting on slopes and on wider ridges, which can optimize soil aeration and improve drainage, making it a key agronomic technique for high-yield cassava cultivation.

[0003] Currently, the cassava planting machines available in China have limited functions and poor structural adaptability. The vast majority can only achieve a single planting method of flat planting on the ridge surface, and only a few models can achieve simple straight planting on the ridge surface. They cannot be compatible with planting modes with higher agronomic requirements, such as slanted planting on the ridge surface and slanted planting on the ridge waist. The insertion mechanism of the existing planting machines is mostly a fixed structure design, and the planting angle and working position are not adjustable. It is difficult to match the tilt angle and lateral working position of the ridge body required for slanted planting on the ridge waist, and thus cannot meet the diverse agronomic needs of different production areas.

[0004] Currently, to achieve non-direct planting methods such as flat placement and oblique insertion, most planting scenarios still rely on manual labor. Manual planting suffers from high labor intensity, low work efficiency, poor consistency in planting depth and angle, and unstable germination rate, which seriously restricts the promotion and application of large-scale and mechanized cassava planting. Therefore, a planting machine adapted to various cassava seedling planting methods is proposed, which can realize four planting methods: flat placement on the ridge, direct insertion on the ridge, oblique insertion on the ridge, and oblique insertion on the ridge waist. It adapts to the cassava planting needs under different soil and ridge conditions, and greatly improves the versatility and operation quality of mechanized planting. Summary of the Invention

[0005] To address the problems in existing technologies, this invention provides a planting machine that adapts to various cassava seedling planting methods. It can realize four planting methods: flat planting on the ridge, straight planting on the ridge, oblique planting on the ridge, and oblique planting on the ridge waist. It is suitable for cassava planting needs under different soil and ridge conditions, and greatly improves the versatility and operational quality of mechanized planting.

[0012] Specifically, the planting frame is equipped with a switching structure for switching between the plug-in mode and the flat mode. The switching structure includes an inclined slide groove at the bottom of the planting frame, and a guide plate with an upward opening and an inclined arrangement is slidably connected in the inclined slide groove.

[0013] The planting frame is equipped with a drive structure for driving the slider to move upward along the chute; when the drive structure is activated, it drives the slider to move upward, and at the same time drives the material guide plate to tilt downward and extend into the ridge surface; the lower edge of the material guide plate is provided with an arc chamfer.

[0014] Specifically, the drive structure includes vertically arranged adjustment slots that run through both sides of the planting frame. A horizontally arranged adjustment rod is provided in the adjustment slot. The adjustment rod passes through the slider and is slidably connected to the slider. Vertically arranged connecting rods are fixedly connected to both ends of the adjustment rods. An adjustment frame is fixedly connected between the top ends of the two sets of connecting rods. An adjustment screw hole is provided on the upper part of the adjustment frame. A vertically arranged adjustment bolt is rotatably connected to the upper surface of the planting frame.

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] To achieve four planting methods—flat planting on the ridge, straight planting on the ridge, angled planting on the ridge, and angled planting on the ridge—and adapt to the different soil and ridge conditions required for cassava planting, thereby significantly improving the versatility and quality of mechanized planting, as one embodiment of the present invention, such as... Figure 1 , Figure 2As shown, the planting machine of the present invention, which is adapted to various cassava seed stem planting methods, includes a vehicle frame 1. Two sets of planting frames 2 are symmetrically arranged on the left and right sides of the vehicle frame 1. Each planting frame 2 is provided with a feeding funnel 3 on its upper part. Each planting frame 2 is provided with a planting structure inside for cutting and planting cassava seed stems. An adjustment structure is fixedly connected to the outside of each planting frame 2 to drive the planting frame 2 to swing along an arc trajectory to adjust the planting angle and planting position. Walking wheels 4 are installed on the bottom of both sides of the vehicle frame 1. The two sets of walking wheels 4 are connected by a drive shaft 5. A transmission component is provided on the vehicle frame 1 to drive the drive shaft 5. The power output end of the transmission component is connected to the planting structure on the corresponding side through a universal telescopic drive shaft. Each planting frame 2 has a planting outlet with an opening facing downwards.

[0038] When in use, first connect the vehicle frame 1 to the traction equipment. The traction equipment drives the whole machine to move forward. The walking wheels 4 roll with the ground and drive the drive shaft 5 to rotate. The drive shaft 5 transmits power synchronously to the planting structures on both sides through the transmission components and the universal telescopic drive shaft, so that the planting structures can operate continuously.

[0039] When performing direct planting on ridges, the cassava seed stems are put into the planting frame 2 from the feed funnel 3. The planting structure first automatically cuts the seed stems, then pushes the cut seed stems downwards and inserts them into the soil from the planting outlet to complete the direct planting.

[0040] When it is necessary to switch to slanted planting on the ridge surface or slanted planting on the ridge waist, the planting frame 2 is swung along the arc trajectory by adjusting the structure, adjusting the planting angle and planting position, and after locking the angle, the slanted planting can be completed according to the straight planting operation process.

[0041] When ridge planting is required, the planting structure only performs the cassava seed stem cutting operation. The planting action stops, and the cut seed stem falls directly from the planting outlet to the ridge planting hole or planting furrow to complete the flat planting. Through a single structure, it is compatible with four planting methods: ridge straight planting, ridge oblique planting, ridge waist oblique planting, and ridge flat planting. It can be flexibly switched according to different soil and ridge conditions, which solves the problems of existing cassava planting machines having single functions, only being able to realize a single planting mode, and not being able to adjust the planting angle and position, and being unable to adapt to diverse agronomic needs. It effectively reduces labor intensity, improves operating efficiency, and enhances the versatility, adaptability, and operating quality of cassava mechanized planting.

[0042] To meet the needs of different planting models, for example, such as Figure 5 As shown, the present invention also includes an adjustment structure comprising an arc-shaped slide rail 6 fixedly connected to the vehicle frame 1, a slide seat 7 fixedly connected to the outside of the planting frame 2 and slidingly engaging with the arc-shaped slide rail 6, the slide seat 7 having a plurality of threaded holes, and a locking bolt 8 threadedly connected to the threaded holes; and an adjustment handle 9 fixedly connected to the outside of the planting frame 2.

[0043] When using the machine, if the planting angle of the planting frame 2 needs to be adjusted to adapt to the slanted planting on the ridge surface or the slanted planting on the ridge waist, first loosen the locking bolt 8 on the slide block 7 to release the locking state between the slide block 7 and the arc-shaped slide rail 6. Then, hold the adjustment handle 9 and pull the planting frame 2 to make the slide block 7 slide stably along the arc-shaped slide rail 6, thereby flexibly adjusting the tilt angle and working position of the planting frame 2. After the adjustment is completed, tighten the locking bolt 8 to make the slide block 7 and the arc-shaped slide rail 6 firmly fixed, ensuring that the planting frame 2 maintains a stable posture during operation. This allows for quick adjustment of the planting angle, adapting to the angle requirements of different planting modes such as straight planting on the ridge surface, slanted planting on the ridge surface, and slanted planting on the ridge waist. This improves the overall adaptability and planting consistency of the machine, and makes the operation simple and the positioning reliable.

[0044] To improve planting efficiency, for example, such as Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the present invention also includes a planting structure comprising two sets of first drive shafts 10 located on the upper inner side of the planting frame 2. Each first drive shaft 10 is fixed with a plurality of circumferentially distributed cutting blades 11, and an arc-shaped elastic rubber seat 12 is fixedly connected between adjacent cutting blades 11. A positioning funnel 13 is provided in the middle inner side of the planting frame 2, and second drive shafts 14 are provided on both sides below the positioning funnel 13. Planting rubber rollers 15 are fixedly connected to each second drive shaft 14.

[0045] When in use, after the cassava seed stem falls from the feed funnel 3 into the planting frame 2, it first enters between the two sets of first drive shafts 10. The first drive shaft 10 drives the cutting blade 11 to rotate and cut the cassava seed stem to a fixed length. During the rotation, the arc-shaped elastic rubber seat 12 simultaneously flexibly clamps and conveys the cassava seed stem downward to ensure stable conveying and neat cutting.

[0046] After being cut, the seed stems are guided and gathered by the central positioning funnel 13 and accurately fall between the two sets of second drive shafts 14. The second drive shafts 14 drive the planting rubber rollers 15 to rotate synchronously. The rubber rollers push the seed stems downward for planting. The angle of the planting frame 2 can be adjusted to complete various planting operations such as straight planting on the ridge, oblique planting on the ridge, and oblique planting on the ridge waist. This realizes integrated continuous operation of cutting, conveying, positioning, and planting, effectively improving planting consistency and work efficiency.

[0047] For example, such as Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, the present invention also includes a vertically arranged partition 16 fixedly connected inside the planting frame 2, and the first drive shaft 10 is rotatably connected to the partition 16; the positioning funnel 13 is fixedly connected to one side of the partition 16; one end of the first drive shaft 10 passes through the partition 16 and is fixedly connected to a drive gear 17, and the two sets of drive gears 17 mesh with each other for transmission; the end of one set of the first drive shaft 10 passes through the planting frame 2 and is connected to the universal telescopic transmission shaft;

[0048] Two sets of rotating shafts 18 are rotatably connected to the partition plate 16, and a first gear 19 is fixedly connected to each rotating shaft 18; the first drive shaft 10 is connected to the rotating shaft 18 through a first pulley 20 and a first transmission belt 21.

[0049] Two sets of inclined sliding grooves 22 are provided on the partition plate 16. A slider 23 is slidably connected in the sliding groove 22. The second drive shaft 14 is rotatably connected to the slider 23. One end of the second drive shaft 14 passes through the slider 23 and is fixedly connected to a transmission gear 24. The transmission gear 24 meshes with the corresponding first gear 19 for transmission.

[0050] In use, the walking wheels 4 and the drive shaft 5 provide power, which drives one of the first drive shafts 10 to rotate through the transmission assembly and the universal telescopic drive shaft. The first drive shaft 10 drives the other first drive shaft 10 to rotate in the opposite direction through the meshing drive gears 17, ensuring that the two sets of cutting blades 11 work together and that the cutting and conveying actions are consistent.

[0051] The first drive shaft 10 simultaneously drives the rotating shaft 18 and the first gear 19 on the partition 16 to rotate via the first pulley 20 and the first transmission belt 21. The first gear 19 meshes with the transmission gear 24 on the second drive shaft 14, thereby driving the second drive shaft 14 and the planting rubber roller 15 to operate. The entire transmission structure adopts mechanical meshing and belt drive cooperation, which has high synchronization and does not require an additional independent power source. The structure is simple and has a low failure rate. It can maintain continuous and stable power output when the planting frame 2 swings to adjust the angle, ensuring that the cutting and planting operations are always stable and reliable.

[0052] To improve the efficiency of horizontal planting operations, for example, such as Figure 6 , Figure 7 , Figure 10 As shown, the present invention also includes a switching structure for switching between plug-in mode and flat mode in the planting frame 2. The switching structure includes an inclined slide groove 25 opened at the lower part of the planting frame 2, and a guide plate 26 with an upward opening and an inclined arrangement is slidably connected in the inclined slide groove 25.

[0053] The planting frame 2 is provided with a drive structure for driving the slider 23 to move upward along the slide groove 22; when the drive structure is activated, it drives the slider 23 to move upward, and at the same time drives the guide plate 26 to extend downward and insert into the ridge surface; the lower edge of the guide plate 26 is provided with an arc chamfer 48.

[0054] When in use, when it is necessary to plant on a flat surface, the drive structure drives the slider 23 to move upward along the groove 22 on the partition 16, so that the transmission gear 24 on the second drive shaft 14 and the first gear 19 on the rotating shaft 18 disengage from each other, and the planting rubber roller 15 stops rotating, and the planting function is turned off.

[0055] At the same time, the drive structure synchronously drives the guide plate 26 in the inclined chute 25 to extend downwards. During the operation, the lower end of the guide plate 26 inserts into the ridge surface and moves forward with the whole machine to complete the hole-opening and grooving operation, pre-opening planting holes that meet the requirements of flat planting. After the cassava seed stem is cut by the cutting blade 11, it falls directly from the positioning funnel 13 onto the guide plate 26 and slides smoothly into the opened planting hole to complete the flat planting. It can quickly realize the tool-free switching between the insertion mode and the flat mode, retain the cutting function and turn off the planting function. The action switching is smooth and the response is rapid. Hole opening and material dropping are carried out simultaneously, without the need for additional hole opening equipment. It effectively simplifies the structure, improves the continuity of operation, ensures that the seed stems are placed neatly and at a consistent depth, and improves the operation efficiency of flat planting.

[0056] To enable rapid switching of planting methods during operations, for example, such as Figure 5 , Figure 8 As shown, the present invention also includes a driving structure comprising a vertically arranged adjustment groove 27 extending through both sides of the planting frame 2, a horizontally arranged adjustment rod 28 disposed within the adjustment groove 27, the adjustment rod 28 passing through the slider 23 and slidably connected to the slider 23; vertically arranged connecting rods 29 fixedly connected to both ends of the adjustment rod 28, and an adjustment frame 30 fixedly connected between the top ends of the two sets of connecting rods 29; an adjustment screw hole is provided at the upper part of the adjustment frame 30, and a vertically arranged adjustment bolt 31 is rotatably connected to the upper surface of the planting frame 2, the adjustment bolt 31 passing through the adjustment screw hole, and a rotating handle 32 fixedly connected to the upper end of the adjustment bolt 31;

[0057] A vertically arranged first hydraulic telescopic rod 33 is fixedly connected to one side of the partition 16. The lower end of the first hydraulic telescopic rod 33 is fixedly connected to the middle of the adjusting rod 28 through a fixed seat. An inclined second hydraulic telescopic rod 34 is fixedly connected inside the inclined slide 25. The upper end of the second hydraulic telescopic rod 34 is fixedly connected to the upper end of the guide plate 26. The first hydraulic telescopic rod 33 and the second hydraulic telescopic rod 34 are connected by a pipeline.

[0058] When switching modes, rotating the handle 32 drives the adjusting bolt 31 to rotate, which in turn drives the adjusting frame 30 to move up and down. The adjusting frame 30 drives the adjusting rod 28 to move up and down synchronously along the adjusting groove 27 via the connecting rod 29. When the adjusting rod 28 moves, it pulls the slider 23 to slide along the sliding groove 22, thereby realizing the engagement and disengagement of the transmission gear 24 and the first gear 19, and completing the start and stop control of the planting function.

[0059] During the upward movement of the adjusting rod 28, the first hydraulic telescopic rod 33 in the middle is simultaneously squeezed. The first hydraulic telescopic rod 33 delivers hydraulic oil to the second hydraulic telescopic rod 34 through the pipeline, causing the second hydraulic telescopic rod 34 to retract. This drives the material guide plate 26 to move downward along the inclined slide 25 into place. Through the mechanical adjustment of the adjusting bolt 31 and the cooperation of the two sets of hydraulic telescopic rods, the synchronous action of the gear clutch and the extension and retraction of the material guide plate 26 is realized. Only one person and one hand are needed to complete the one-button switching between the insertion mode and the flat mode. It has strong stability and can quickly switch the planting mode during operation, effectively improving the convenience of operation and the continuity of operation of the whole machine.

[0060] To adapt to continuous multi-angle operations, for example, such as Figure 2 , Figure 3 , Figure 4 As shown, the present invention also includes a transmission assembly comprising a second pulley 35 fixedly connected to the transmission shaft 5, a third pulley 36 rotatably connected to the vehicle frame 1, and the second pulley 35 and the third pulley 36 being connected by a second transmission belt 37; a worm gear 38 is fixedly connected to the coaxial end of the third pulley 36, and a worm wheel 39 is engaged below the worm gear 38, and the worm wheel 39 is rotatably connected to the vehicle frame 1.

[0061] The universal telescopic drive shaft includes a first shaft body 40 and a second shaft body 41. The first shaft body 40 has a spline groove 42, and the second shaft body 41 has a spline shaft 43 that slides with the spline groove 42. Universal joints 44 are provided at the ends of the first shaft body 40 and the second shaft body 41 that are far apart from each other. One set of universal joints 44 is connected to the worm gear 39, and the other set of universal joints 44 is connected to a first drive shaft 10.

[0062] In use, the walking wheel 4 drives the drive shaft 5 to rotate. The second pulley 35 on the drive shaft 5 drives the third pulley 36 to rotate synchronously through the second drive belt 37. The third pulley 36 drives the worm 38 to rotate. The worm 38 meshes with the worm wheel 39 for transmission. When the worm wheel 39 rotates, it drives the universal joint 44 at one end to rotate. The power is transmitted to the universal joint 44 at the other end through the telescopic cooperation of the first shaft 40, the second shaft 41, and the spline shaft 43 and the spline groove 42. Finally, it drives the first drive shaft 10 to operate continuously, realizing the stable transmission of power from the vehicle frame 1 to the planting frame 2.

[0063] By combining belt drive, worm gear 38, worm wheel 39 and universal telescopic drive shaft, the planting frame 2 can adjust its angle by swinging along the arc-shaped slide rail 6. The spline telescopic and universal joint 44 adaptively compensate for changes in angle and distance, maintaining continuous power without interruption. This allows for continuous operation at multiple angles and greatly improves the reliability and versatility of the whole machine.

[0064] For example, such as Figure 2 As shown, the present invention also includes a quick-connect connector 45 for quick docking with traction equipment fixedly connected to the side of the vehicle frame 1 near the walking wheel 4; and two sets of ridge-opening discs 46 symmetrically arranged in front of the quick-connect connector 45 on the vehicle frame 1.

[0065] When in use, the vehicle frame 1 can be quickly connected and fixed to tractors and other traction equipment via quick-connect connectors 45. It is easy to assemble and disassemble and the connection is firm, which can meet the needs of quick splicing operations in the field.

[0066] Two sets of ridge-opening discs 46 are set in front of the quick-connect connector 45 on the vehicle frame 1. They can pre-open furrows, ridges and loosen the soil as the whole machine moves forward, providing regular planting conditions for subsequent cassava seed planting, reducing seed damage and improving planting verticality and seedling emergence rate.

[0067] For example, such as Figure 1 As shown, the present invention also includes a plurality of mounting seats 47 fixedly connected to the side of the vehicle frame 1 away from the quick-connect connector 45. The mounting seats 47 are used for detachably connecting the manned operating platform and the cassava seed storage bracket.

[0068] When in use, multiple mounting seats 47 are set on the side of the vehicle frame 1 away from the quick-connect connector 45. They can quickly and detachably connect the manned operating platform and the cassava seed storage rack according to the operation requirements. This provides the operator with a stable and safe working position, which is convenient for real-time observation, replenishment and mode switching. It can also store the cassava seed in an orderly manner to ensure continuous and smooth supply.

[0069] When using this invention, before operation, the vehicle frame 1 is quickly connected and fixed to the tractor or other traction equipment via quick-connect connectors 45, which is convenient for disassembly and assembly and meets the needs of quick attachment in the field; the two sets of ridge-opening discs 46 at the front of the vehicle frame 1 move forward with the whole machine, and pre-ditch, ridge, and loosen the soil on the ridge surface, providing regular planting conditions for subsequent planting, reducing seed stem damage, and improving planting verticality and seedling emergence rate;

[0070] The traction device drives the whole machine to move forward. The walking wheels 4 roll with the ground and drive the drive shaft 5 to rotate. The drive shaft 5 transmits power synchronously to the planting structures on both sides through the transmission components and the universal telescopic drive shaft, so that the planting structures can operate continuously. The power is taken from the walking wheels 4, without the need for an additional independent power source. The structure is simple, the failure rate is low, and the power transmission is stable and continuous.

[0071] When performing direct planting on ridges, cassava seed stems are fed into the planting frame 2 through the feed funnel 3. The seed stems enter between the two sets of first drive shafts 10. The first drive shafts 10 drive the cutting blades 11 to rotate and complete the fixed-length cutting. The arc-shaped elastic rubber seat 12 simultaneously forms a flexible clamp and downward conveying for the seed stems, ensuring stable conveying and neat cutting. After cutting, the seed stems are guided and gathered by the positioning funnel 13 and fall between the two sets of second drive shafts 14. The planting rubber roller 15 rotates and squeezes and pushes them downward for planting. They are then planted into the soil from the planting outlet, realizing integrated continuous operation of cutting, conveying, positioning and planting, improving planting consistency and work efficiency.

[0072] When switching to slanted planting on the ridge surface or slanted planting on the ridge waist, first loosen the locking bolt 8 on the slide block 7 to release the locking state between the slide block 7 and the arc-shaped slide rail 6. Hold the adjustment handle 9 and pull the planting frame 2 to make the slide block 7 slide stably along the arc-shaped slide rail 6, flexibly adjusting the tilt angle and working position of the planting frame 2. After adjustment, tighten the locking bolt 8 to fix it tightly, ensuring the stable working posture of the planting frame 2, realizing quick and adjustable planting angle, adapting to the angle requirements of different planting modes such as straight planting on the ridge surface, slanted planting on the ridge surface, and slanted planting on the ridge waist, and improving the overall adaptability of the machine.

[0073] When planting on a ridge, rotating the handle 32 drives the adjusting bolt 31 to rotate, which in turn drives the adjusting frame 30, connecting rod 29 and adjusting rod 28 to rise and fall synchronously. The adjusting rod 28 pulls the slider 23 to slide along the slide groove 22, causing the transmission gear 24 to disengage from the first gear 19, and the planting rubber roller 15 to stop rotating, thus turning off the planting function. The adjusting rod 28 moves up and simultaneously squeezes the first hydraulic telescopic rod 33, which delivers hydraulic oil to the second hydraulic telescopic rod 34 through the pipeline, causing the second hydraulic telescopic rod 34 to retract. This drives the material guide plate 26 to extend downward along the inclined slide groove 25. The arc-shaped chamfer 48 at the lower end of the material guide plate 26 is inserted into the ridge surface and completes the hole-opening and grooving operation as the whole machine moves forward. The cut seed stems fall through the positioning funnel 13 onto the material guide plate 26 and slide smoothly into the planting hole to complete the flat planting. Only one person and one hand are needed to adjust and switch modes with one button. Hole opening and material dropping are carried out simultaneously, eliminating the need for additional hole opening equipment and improving the continuity of operation and the efficiency of flat planting.

[0074] During operation, the mounting base 47 at the rear of the vehicle frame 1 can be detachably connected to the manned operating platform and the cassava seed storage bracket, providing operators with a stable and safe working position, facilitating real-time observation, material replenishment and mode switching, while orderly storing cassava seed to ensure continuous and smooth material supply, adapting to long-term large-scale operations and reducing labor intensity.
