Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery and equipment, and specifically discloses a rotary tillage, fertilization, ridging, film covering and hole sowing all-in-one machine. Background Art

[0002] In the process of dryland rice cultivation, in order to achieve water conservation, increase production, cover grass, reduce fertilizer and reduce pesticide use, ridge-forming and film-covering are required. The black fully biodegradable film covering the ridge surface can reduce water evaporation, inhibit weed growth, block fertilizer loss, and suffocate overwintering old larvae. Currently, agricultural machinery equipment used for dryland rice film-covering cultivation on the market has multiple functions such as rotary tillage, fertilization, ridge-forming, film-covering and hole-seeding, but its actual use effect is not ideal, especially the film-covering mechanism, which only has a simple film-covering function, but the edge sealing during the film-covering process, the film breaking and head sealing during the machine turning process require manual assistance.

[0003] For example, the invention patent with application number CN201710045231.8 discloses a rice dry seeding machine, which can complete the operations of leveling the land, laying drip irrigation pipes, laying film, pressing soil, shaping, furrow planting, and sowing at one time. The machine consists of a traction part, a land preparation part, a pipe laying part, a transmission part, a furrow film laying and soil pressing part, a shaping part, a film edge soil pressing part, and a sowing part. The land preparation part consists of a soil leveling shovel, a soil pressing roller, and a furrowing plow. The transmission part consists of a universal transmission shaft, a gearbox, a chain, and a sprocket to drive the main shaft to rotate. The furrow film laying and soil pressing part: four sets of soil throwing discs are installed on the main shaft, and multiple blades are installed on the soil throwing disc. When the main shaft rotates, the soil is thrown up and pressed on the film to complete the soil pressing operation. The shaping part is to smooth the soil and press it into a ridge shape. Although the rice dry seeding machine disclosed in this invention has the functions of land preparation, film laying, soil pressing, and sowing, the actual effects of many functions are not ideal. Taking the film-laying action as an example, when the machine turns around, not only does it need to be manually cut, but it also needs to be manually covered with soil after the film is cut to prevent the ground film from being blown away by strong winds. Then, when the machine turns around and lays the film again, it is necessary to manually tear off the film and cover it with soil again, resulting in the entire dryland rice planting being unable to be completed automatically. In addition, the fertilization of traditional machines is mainly driven by the motor to drive the fertilizer discharge shaft to rotate, and then the fertilizer discharge shaft drives the internal fertilizer wheel of the fertilizer discharger to rotate, which results in the machine's driving speed changing. The amount of fertilizer remains unchanged, so the amount of fertilizer per unit area of ​​soil cannot be kept consistent, and there is a problem of too much or too little fertilizer, which is not conducive to the subsequent uniform growth of rice. Therefore, in view of the above-mentioned series of shortcomings of the existing dryland rice seeding machine, the present application proposes a rotary tillage, fertilization, ridging, film covering, and hole sowing all-in-one machine that can effectively solve the above-mentioned problems. Summary of the invention

[0004] The purpose of the present invention is to provide a rotary tillage, fertilization, ridging, film covering and hole sowing all-in-one machine to solve the technical problems existing in the film covering and fertilization processes of the existing dry land rice seeding machines during operation.

[0006] As a further configuration of the above scheme, the driving mechanism includes a first hydraulic rod installed on the frame, the end of the first hydraulic rod is connected to a rack, and the end of the rotating rod is provided with a gear meshing with the rack.

[0007] As a further configuration of the above solution, the laminating roller is arranged on a circular path where the cutting serrated blade rotates along with the arc-shaped outer shovel plate.

[0008] As a further configuration of the above scheme, the front and rear sides of the chassis are both provided with connecting plates extending to the left, the right end of the frame is rotatably connected to the connecting plate, a third hydraulic rod is rotatably connected to the chassis, and the end of the third hydraulic rod is connected to the frame.

[0009] As a further configuration of the above scheme, the fertilizer discharge mechanism includes a fertilizer box arranged at the upper end of the chassis, and the lower end of the fertilizer box is connected to a row of fertilizer dischargers, and each fertilizer discharger is connected to a fertilizer discharge pipe extending into the chassis through a pipeline.

[0010] As a further configuration of the above scheme, the front side surface of the chassis is rotatably connected to a lever rotating bar which is generally U-shaped, one end of the lever rotating bar is connected to the chassis through a tension spring, and the other end is provided with a tension stabilizing pressure wheel, and a first transmission wheel is rotatably provided on the lever rotating bar between the tension stabilizing pressure wheel and the rotating connection, a gripping power wheel is provided at the end of the first transmission wheel, a second transmission wheel is provided on the chassis, a third transmission wheel is provided at the end of the fertilizer discharge shaft of the fertilizer discharger, a first transmission member is provided between the first transmission wheel and the second transmission wheel, and a second transmission member is provided between the second transmission wheel and the third transmission wheel.

[0011] As a further configuration of the above scheme, the rotary tillage mechanism includes a stubble-killing rotary tillage mechanism and a soil-crushing rotary tillage mechanism, and the stubble-killing rotary tillage mechanism, the soil-crushing rotary tillage mechanism and the ridging roller are sequentially arranged in the chassis from right to left.

[0012] As a further configuration of the above scheme, the front and rear sides of the chassis are both provided with side openings located on the left side of the soil crushing and rotary tillage mechanism, and the soil spreading trough is connected to the outer end of the side opening.

[0013] As a further configuration of the above scheme, furrow openers are provided on both the front and rear sides of the right end of the chassis, and a limited depth wheel is provided on the right end of the chassis between the two furrow openers.

[0014] As a further configuration of the above scheme, the hole-seeding mechanism includes a plurality of duck-billed hole-seeders arranged side by side, and each duck-billed hole-seeder is connected to a seed box, and a plurality of pressing wheels are arranged side by side, and each pressing wheel is aligned with the duck-billed hole-seeder one by one along the travel path of the machine.

[0015] The rotary tillage, fertilization, ridging, film covering, and hole seeding integrated machine disclosed in the present invention is connected to a tractor through a three-point suspension when in operation, and is towed and moved by the tractor. During the driving process of the integrated machine, the rotary tillage mechanism successively removes stubble and crushes the soil to make the soil loose, and then the ridging roller piles the soil toward the middle to form a ridge surface, and in the process of forming the ridge surface, the fertilizer discharge mechanism evenly sprinkles granular fertilizer into the soil, and at the same time, the furrow opener opens furrows on both sides of the ridge surface, and a small amount of soil in the rotary tillage process is discharged into the furrow through the soil discharge guide groove to form a strip soil ridge.

[0016] Next, the mulch film removed from the mulch film unloading roller is spread on the ridge surface by the mulch film pressing roller to complete the mulch film laying. At the same time, the mulch film pressing disc at the ridge edge presses the front and rear sides of the mulch film into the bottom of the gully. Then, the soil covering disc pushes the strip ridge soil to the upper surface of the front and rear sides of the mulch film to cover it, and the soil pressing wheel compacts the soft soil covering both sides of the mulch film. During the driving process of the machine, the duckbill mechanism on the outer surface of the duckbill hole seeder punctures the mulch film, and then the rice seeds are released and fall into the holes on the ridge surface. Finally, the rice seeds are compacted by the pressing wheel, so that the rice seeds are fully in contact with the soil and can fully absorb the moisture and nutrients in the soil.

[0017] When the integrated machine drives to the end of the field and needs to turn around, the film cutting and soil covering mechanism is started first. During its operation, the meshing transmission between the gear and the rack allows the arc-shaped outer shovel plate to rotate downward counterclockwise, and the cutting serrated blade cuts the mulch film in the process of pressing it into the ridge surface. At the same time, when the arc-shaped outer shovel plate is extended into the soil, the hinge plate will be opened by the soil squeezing force, and the soft soil will be filled into the cavity between the arc-shaped outer shovel plate and the anti-fall partition under the action of the squeezing force. In addition, the cutting serrated blade can press the cut mulch film to the lower end of the film pressing roller, and when the whole machine turns around and is lifted, the clamped film head is lifted together with the random tool When the machine turns around and the operation starts, the arc-shaped outer shovel plate rotates clockwise under the meshing transmission of the rack and the gear, so as to first release the pressing effect of the cutting serrated blade on the ground film, and let the end of the ground film cover the ridge surface; in the clockwise rotation process of the arc-shaped outer shovel plate, the hinge plate will seal the lower end between the arc-shaped outer shovel plate and the anti-fall partition plate to prevent soil from falling; when the arc-shaped outer shovel plate rotates clockwise to the upper right side of the film pressing roller, the soil in the cavity will fall from the other end by gravity and fall on the upper surface of the end of the ground film, so as to cover the end of the new row of ground film with soil to prevent the end of the ground film from being blown up by strong wind.

[0018] When the cutting sawtooth blade cuts the ground film, the soil covering head mechanism is started, and the inclined plug plate is inserted into the soil. During the insertion of the soil, the soil-carrying plate is rotated upward by the soil resistance until it fits with the inclined plug plate. Then, when the inclined plug plate is pulled back to pull out the soil, the soil-carrying plate will rotate in the opposite direction until it abuts against the limit strip, and a small amount of soil will be brought up by the soil-carrying plate. The brought up soil will then slide down from the upper surface of the soil-carrying plate, and finally the fallen soil will cover the end head position of the cut ground film, thereby covering the end of the ground film after the operation is completed, and preventing the end of the ground film from being blown up by strong wind.

[0019] In addition, during the movement of the machine, the gripping power wheel will cause the first transmission wheel to rotate, and then the first transmission member and the second transmission member will cause the fertilizer groove wheels in all fertilizer dispensing devices to rotate synchronously with the fertilizer dispensing shaft to complete the fertilizer dispensing action, and the speed of the fertilizer dispensing wheel rotation depends on the speed of the machine movement, ensuring the uniformity of fertilization under the ridge surface soil. When the gripping power wheel comes into contact with a hard object in the soil, the hard object will push the gripping power wheel upward, and at this time the lever rotation bar will rotate around the pin shaft to self-adjust. When the gripping power wheel is lifted, the tension stabilizing pressure wheel will press against the first transmission member, thereby effectively preventing the first transmission member from falling off between the first transmission wheel and the second transmission wheel, ensuring the stable operation of the fertilizer dispensing device transmission system.

[0020] Finally, since the film covering, hole sowing and suppression parts of the machine are arranged at the tail of the rotary tillage and ridging part, a certain length is added, resulting in the inability to bring the rotary tillage and ridging part close to the end of the farmland when the whole machine starts to work. The present invention further adopts a folding design, when the machine starts to work, the frame at the tail of the rotary tillage and ridging is completely folded and lifted, so that the rotary tillage and ridging part starts working close to the head of the field, and when the rear frame length is sufficient, the frame is lowered, thereby solving the common problem that other rotary tillage and ridging machines can only start working from the middle of the field.

[0021] Compared with the prior art, the present invention has the following beneficial effects: The rotary tillage, fertilization, ridging, film covering, hole sowing all-in-one machine disclosed in the present invention can automatically realize the functions of stubble removal, rotary tillage, fertilization, furrowing and ridging, film covering, hole sowing, pressing, film cutting, film releasing, and capping during the process of dry land rice planting, thereby making the dry land film covering planting of rice more efficient and achieving better planting effects.

[0022] The integrated machine disclosed in the present invention can not only quickly cut off the ground film through the film-cutting and covering mechanism and the covering and sealing mechanism before the machine turns around, and press the end of the ground film connected to the film unloading roller onto the film pressing roller to avoid dragging of the ground film during the turning process of the machine, but also store a certain amount of soil inside it. When the machine completes the turning around and starts a new line of operation, the soil stored in the cavity can be reversely discharged to the end of the ground film without manual assistance of covering and pressing. In addition, after the ground film is cut off, it can be obliquely inserted into the soil through the covering and sealing mechanism, and then a certain amount of soil can be brought up during the process of pulling out, so that this part of the soil can cover the end of the cut ground film, and there is no need for manual assistance of covering and pressing, realizing the full automation of the covering process. The design of the entire film-cutting and covering mechanism and the covering and sealing mechanism is novel and ingenious, which effectively solves the deficiency of the existing covering mechanism in the process of turning around the machine that requires manual assistance.

[0023] During the film covering operation, the all-in-one machine disclosed in the present invention can, on the one hand, discharge the broken soil generated during the rotary tillage process into the furrows on both sides; on the other hand, in conjunction with the sequential operation of the film pressing plate, the soil covering plate and the soil pressing wheel, it can press and fix both sides of the ground film covering the ridge surface, thereby ensuring the stability of the ground film after covering and improving the film covering effect.

[0024] During the operation of the fertilizer spreader in the present invention, the gripping power wheel converts the power of the machine's straight-line travel into rotational power, and then the fertilizer discharge shaft in the fertilizer spreader rotates synchronously through the power transmission of the transmission member, so that the fertilizer discharge speed of the fertilizer spreader can be adjusted synchronously with the travel speed of the machine, thereby ensuring the uniformity of fertilization of the ridge surface soil; in addition, when encountering hard objects in the soil, the gripping power wheel can not only be automatically lifted up and adjusted, but also the tension stabilizing pressure wheel can be pressed against the transmission member, thereby effectively preventing the transmission member from falling off during the adjustment process, thereby ensuring the stable operation of the fertilizer spreader transmission system.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Figure 1-8 , and describes the application in detail with reference to embodiments. Example 1

[0029] Embodiment 1 discloses a rotary tillage, fertilization, ridging, film covering, and hole sowing all-in-one machine, see the attached Figure 1-4 , including a chassis 1 and a frame 2, the frame 2 is connected to the left end of the chassis 1, a three-point suspension 3 is arranged at the right end of the upper surface of the chassis 1, and the entire integrated machine can be connected to the tractor through the three-point suspension 3. Ditch openers 4 are arranged on both the front and rear sides of the right end of the frame 2, and a depth limiting wheel 5 is installed on the right end of the frame 2 between the two trench openers 4. When the entire integrated machine is moving with the tractor, the depth limiting wheel 5 can limit the horizontal height of the entire integrated machine relative to the ground, and the trench openers 4 on the front and rear sides perform trenching operations on the ground soil.

[0030] Inside the chassis 1, there are arranged a stubble-killing rotary tillage mechanism 6, a soil-crushing rotary tillage mechanism 7 and a ridging roller 8 from right to left. The stubble-killing rotary tillage mechanism 6 and the soil-crushing rotary tillage mechanism 7 have similar structures, both of which are composed of a rotary tillage shaft + a rotary tillage blade, and the power of the tractor is transmitted to the two through a reducer, so that during the travel of the frame, the stubble-killing rotary tillage mechanism 6 first turns over and crushes the roots of the crops in the field, and then the soil-crushing rotary tillage mechanism 7 further crushes the turned-over soil to form loose soil. The ridging roller 8 then piles up the loose soil after rotary tillage to form a ridge surface, and the ridging roller 8 is connected to the shaft end of the soil-crushing rotary tillage mechanism 7 through a chain to achieve power transmission, and finally the furrows formed in the field by the furrow opener 4 are located on the front and rear sides of the ridge surface.

[0031] A fertilizer box 9 is provided at the left end of the upper surface of the chassis 1, and a row of fertilizer dispensers 10 are connected to the lower end of the fertilizer box 9, and the lower end of the fertilizer dispenser 10 is connected to a fertilizer pipe 101 extending into the chassis 1 and located between the ridging roller 8 and the soil crushing rotary tillage mechanism 7 through a pipeline, so that granular fertilizer is evenly spread into the soil during the process of loosening the soil to form a ridge surface. In addition, side openings are provided on both the front and rear sides of the chassis 1, and a downwardly bent soil spreading trough 11 is connected to the outer end of the side opening. The soil spreading trough 11 is arranged on the left side of the soil crushing rotary tillage mechanism 7, so that when the soil crushing rotary tillage mechanism 7 breaks up the soil blocks, a small amount of crushed soil is discharged from the soil spreading trough 11 to the front and rear sides of the chassis 1, and then falls into the gullies on the front and rear sides of the ridge surface to form a strip soil ridge.

[0032] The film coating mechanism 12, the film cutting and soil covering mechanism 13, the soil covering and sealing mechanism 14, the hole sowing mechanism 15 and the pressing wheel 16 are arranged on the frame 2 from right to left. Among them, the film coating mechanism 12 includes a film unloading roller 121 rotatably mounted on the upper end of the frame 2, and a film pressing roller 122 is rotatably arranged in the frame 2 below the film unloading roller 121.

[0033] Reference Figure 5 and attached Figure 6 The film-breaking and soil-covering mechanism 13 includes an arc-shaped outer shovel plate 131, and a fan-shaped end plate 132 is provided at the front and rear ends of the arc-shaped outer shovel plate 131. A rotating rod 133 is provided between the ends of the two fan-shaped end plates 132, and the rotating rod 133 is rotatably mounted on the frame 2, and then a driving mechanism for driving the arc-shaped outer shovel plate 131 to rotate around the central axis of the rotating rod 133 is also provided on the frame 2. The driving mechanism includes two front and rear first hydraulic rods 134, and the lower ends of the two first hydraulic rods 134 are connected to racks 135, and then gears 136 meshing with the corresponding racks 135 are provided at both ends of the rotating rod 133, so that in the process of the first hydraulic rod 134 extending or shortening, the arc-shaped outer shovel plate 131 rotates counterclockwise or clockwise around the rotating rod 133 through the meshing transmission between the rack and the gear. At the same time, a cutting sawtooth blade 139 is installed at the lower end of the arc-shaped outer shovel plate 131, and the cutting sawtooth blade 139 can press on the bottom of the film pressing roller 122 after rotating a certain angle counterclockwise with the arc-shaped outer shovel plate 131. An anti-falling partition plate 137 is arranged between the two fan-shaped end plates 132 inside the arc-shaped outer shovel plate 131, and a hinge plate 138 is rotatably connected to one end of the anti-falling partition plate 137 close to the cutting sawtooth blade 139.

[0034] When the machine travels to the ridge and needs to turn around, the first hydraulic rod 134 is started, and the arc-shaped outer shovel plate 131 rotates downward counterclockwise under the meshing transmission of the rack and the gear, and the cutting serrated blade 139 cuts the ground film while pressing it into the ridge surface. At the same time, when the arc-shaped outer shovel plate 131 extends into the soil, the hinge plate 138 is opened by the soil squeezing force, and part of the soil is filled into the space between the arc-shaped outer shovel plate 131 and the anti-fall partition plate 137. The cutting serrated blade 139 can press the cut ground film against the lower end of the film pressing roller 122 to prevent the ground film from being dragged during the machine turning around. When the machine has completed its U-turn, the first hydraulic rod 134 is controlled to extend and retract in the opposite direction, and the arc-shaped outer shovel plate 131 is rotated clockwise under the meshing transmission of the rack and the gear, thereby first releasing the pressing effect of the cutting serrated blade 139 on the ground film, allowing the end of the ground film to cover the ridge surface, and then in the process of the arc-shaped outer shovel plate 131 turning out the soil, the hinge plate 138 will block the lower end between the arc-shaped outer shovel plate 131 and the anti-fall partition plate 137 to prevent soil from falling, and when the arc-shaped outer shovel plate 131 rotates clockwise to the upper right of the film pressing roller 122, the soil dug up inside will be discharged from the other end and fall on the upper surface of the end of the ground film, thereby covering the end of the new row of ground film with soil to prevent the end of the ground film from being blown up by strong wind.

[0035] The soil covering head mechanism 14 includes a second hydraulic rod 141 installed on the frame 2 tilted to the right, and an inclined plate 142 is connected to the lower end of the second hydraulic rod 141. The inclined plate 142 can extend downward to the right side of the ground film cutting position along its tilting direction. A limit bar 143 is provided at the lower end of the left side of the inclined plate 142, and a soil carrying plate 144 is rotatably connected to the left side of the inclined plate 142 above the limit bar 143, and the soil carrying plate 144 will be limited by the limit bar 143 during the downward rotation until it rotates to a certain angle. The soil covering and sealing mechanism 14 in this embodiment 1 operates synchronously with the film cutting and covering mechanism 13. After the cutting serrated blade 139 cuts off the ground film, the inclined plug plate 142 will be inserted into the soil, and in the process of inserting the soil, the soil plate 144 will rotate upward due to the soil resistance until it is in contact with the inclined plug plate 142. Then, in the process of the inclined plug plate 142 pulling the soil upward, the soil plate 144 will rotate in the opposite direction until it abuts against the limit strip 143, and a small amount of soil will be brought up by the soil plate 144, and the brought up soil will slide down from the upper surface of the soil plate 144, and finally the slid down soil will cover the cut end position of the ground film, thereby achieving the sealing effect on the cut ground film and preventing the end of the ground film from being blown up by strong wind.

[0036] The hole sowing mechanism 15 includes a plurality of duckbill hole sowers 151 arranged side by side, and a seed box 152 is connected to the upper end of each duckbill hole sower 151. During the sowing process, the duckbill mechanism on the outer surface of the duckbill hole sower 151 punctures the ground film, and then releases the rice seeds and drops them on the ridge surface. In addition, a film pressing plate 17 is installed on the frame 2 on both sides of the front and rear of the hole sowing mechanism 15, and the film covering the ground film on both sides can be pressed into the soil through the film pressing plate 17. Finally, a soil covering plate 18 is installed on the frame 2 on the left side of the film pressing plate 17. After the film pressing plate 17 presses the ground film into the soil, the soil in the gully is pressed on its upper end by the soil covering plate 18, ensuring a better and more stable film covering effect.

[0037] There are multiple pressing wheels 16 arranged side by side, and each pressing wheel 16 is aligned with the duckbill hole sower 151 one by one along the driving path of the machine. After the duckbill hole sower 151 sows the rice seeds on the ridge surface, the pressing wheel 16 presses the rice seeds into the soil to ensure that the rice seeds can fully absorb the nutrients in the soil and grow. Finally, a soil pressing wheel 19 is installed at the left end of the frame 2 on both sides of the front and rear of the pressing wheel 16. The soil pressing wheel 19 can push the soil covering plate 18 to the side end of the ground film and press it on the ground, which can stabilize the film pressing effect on the one hand, and level the bottom of the gully on the other hand. Example 2

[0038] Example 2 discloses a rotary tillage, fertilization, ridging, film covering and hole sowing all-in-one machine which is optimized based on the technical solution in Example 1. The similarities between it and Example 1 will not be described again.

[0039] In this embodiment 2, a U-shaped lever rotating bar 20 is rotatably connected to the lower end of the front side of the chassis 1 through a pin shaft, and one end of the lever rotating bar 20 is connected to a tension spring 21, and the other end of the tension spring 21 is connected to the chassis 1. A tension stabilizing pressure wheel 22 is rotatably connected to the other end of the lever rotating bar 20, and then a first transmission wheel 23 is rotatably set on the lever rotating bar 20 between the tension stabilizing pressure wheel 22 and the pin shaft rotation connection, and a gripping power wheel 24 is fixedly connected to the front end of the first transmission wheel 23, and the lower end of the gripping power wheel 24 can be extended into the bottom of the gully to a certain depth. A second transmission wheel 25 is arranged at the upper end of the chassis 1, and then a third transmission wheel 26 is connected to the outer end of the fertilizer discharge shaft of a row of fertilizer discharging devices 10, a first transmission member is arranged between the first transmission wheel 23 and the second transmission wheel 25, and a second transmission member is arranged between the second transmission wheel 25 and the third transmission wheel 26. Specifically, the first transmission member and the second transmission member can be a transmission chain or a synchronous belt, and the first transmission wheel 23, the second transmission wheel 25 and the third transmission wheel 26 can select sprockets or synchronous wheels accordingly.

[0040] Through the above design, in the process of driving the machine, the gripping power wheel 24 will rotate with the movement of the machine, and then the fertilizer shaft in the fertilizer dispensing device 10 will rotate at a corresponding speed through the transmission action of the first transmission member and the second transmission member, so that the fertilizer dispensing wheel inside the fertilizer dispensing device 10 can automatically adjust the dispensing speed of the granular fertilizer according to the speed of the machine, thereby ensuring the uniformity of fertilizing the ridge surface soil. In addition, when the gripping power wheel 24 encounters a harder object (such as a stone) in the soil, the stone will push the gripping power wheel 24 upward, and at this time, the lever rotating bar 20 will rotate around the pin shaft to self-adjust. When the gripping power wheel 24 is lifted, the tension stabilizing pressure wheel 22 will press against the first transmission member, thereby effectively preventing the first transmission member from falling off between the first transmission wheel 23 and the second transmission wheel 25, thereby ensuring the stability of the operation of the fertilizer dispensing device transmission system.

[0041] In addition, since the film covering, hole sowing and suppression parts of the machine are arranged at the tail of the rotary tillage and ridging part, a certain length is added, resulting in the inability to bring the rotary tillage and ridging part close to the end of the farmland to start the operation when the whole machine starts working. The frame 2 in this embodiment 2 is rotatably connected to the chassis 1. In the specific design, a connecting plate 27 extending to the left is fixed on the front and rear sides of the chassis 1, and then the right end of the frame 2 is rotatably connected to the connecting plate 27 through a pin. At the same time, a third hydraulic rod 28 is rotatably connected to the upper end of the chassis 1, and the telescopic end of the third hydraulic rod 28 is connected to the upper end of the frame 2, so that when the machine turns around or is transported, the entire frame 2 and its attached parts can be lifted up by the third hydraulic rod 28. When the machine starts working, the frame at the tail of the rotary tillage and ridging is completely folded and lifted, so that the rotary tillage and ridging part starts working close to the head of the field, and the frame is lowered when the operation is sufficient to the rear tail frame length. It not only solves the common problem of other rotary tillage and hole seeding machines that can only start operation from the middle of the field, but also reduces the space occupied during the transportation of the machine, and can also avoid damage to the ridge surface with film covering and sowing when the machine turns around.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
