Description

Technical Field

[0001] The invention relates to the technical field of rotary tillage and sowing equipment, in particular to an all-in-one rotary sowing and furrowing machine. Background Art

[0002] The rotary tillage sowing and furrowing machine is an agricultural machinery equipment integrating rotary tillage, sowing, pressing and furrowing. The existing rotary tillage sowing and furrowing machine includes a frame, which is driven forward by the existing walking mechanism. The frame is provided with a rotary tillage mechanism, a furrowing mechanism, a sowing mechanism and a pressing roller group in sequence. The rotary tillage mechanism includes a rotating shaft and a plurality of rotary tillage blades arranged outside the rotating shaft. The rotary tillage gear box can drive the rotary tillage blade shaft to rotate, thereby driving the rotary tillage blades to rotate and rotary till the land; the furrowing mechanism includes two notched discs respectively arranged on both sides of the frame. When the frame moves, the ground on both sides of the notched disc frame is excavated and furrows are formed. A field ridge higher than the furrow is formed between the two furrows. The sowing mechanism includes a plurality of double disc furrowing devices and a seed feeding mechanism. The pipe mouth of the seed feeding mechanism is arranged at the rear end of the double disc furrowing device. After the disc furrowing device completes the furrowing of the planting furrow, the seed feeding mechanism controls the seeds to fall into the opened planting furrow, and then the pressing roller is used to complete the covering and leveling.

[0003] However, during the use of traditional rotary tillage and seeding machines, the distances between several double-disc furrowing devices arranged side by side are small, and the discharged soil is easily accumulated between adjacent double-disc furrowing devices. The accumulated soil increases the running resistance of the double-disc furrowing devices, and even causes congestion of some double-disc furrowing devices, resulting in excessive travel resistance of the rotary tillage and seeding furrowing machine. At the same time, the furrowing resistance of the notched disc is large, which further easily causes difficulty in the travel of the rotary tillage and seeding furrowing machine, affecting the normal operation of the rotary tillage and seeding furrowing machine.

[0018] The present invention has the following beneficial effects:

[0019] 1. Before the disc furrow opener 7 opens the furrow, the present invention performs a primary compaction by means of the first compaction roller in cooperation with the soil retaining disc, increasing the soil density in the area outside the area that needs to be opened as the planting furrow at the top of the ridge. During the subsequent furrow opening process of the planting furrow, the soil on both sides of the disc is not prone to collapse, facilitating the shaping of the planting groove, and the soil is flat, improving the furrow opening effect of the planting furrow. After the soil is compacted, the space on both sides of the disc furrow opener increases, avoiding soil accumulation between adjacent disc furrow openers and causing congestion, reducing the resistance during the furrow opening process of the planting furrow. At the same time, the notched disc and the digging bucket disc open the furrow in two steps, further reducing the resistance of the rotary seeding and furrow opening machine during travel. After the digging bucket disc opens the furrow, the side walls of the ridge are leveled in cooperation with the compaction discs on both sides of the compaction roller group, ensuring the shaping effect of the ridge groove, and the secondary compaction of the second compaction roller ensures that the ridge will not collapse during the planting furrow opening process, improving the stability of the ridge.

[0020] 2. The present invention drives the rotating ring plate to rotate in the opposite direction through synchronous transmission of the transmission shaft, so that the movable soil shoveling plate and the fixed soil shoveling plate cooperate to shovel the soil between adjacent compaction roller units, keeping the soil behind the first compaction roller flat, making the soil on which the disc furrow opener acts loose soil. Without increasing the furrow opening resistance of the disc furrow opener, it reduces the soil volume generated during the furrow opening of the planting groove, further avoiding soil congestion between the disc furrow openers. At the same time, the excavated soil is conveyed from the discharge pipe to the planting furrow after the seeds are filled, ensuring that there is enough soil backfilled into the planting groove later, ensuring the burial depth of the seeds. Moreover, the movable soil shoveling plate drives the discharge pipe to vibrate in sequence, and the vibration frequency of the discharge pipe increases as the rotational speed of the transmission shaft increases, that is, when the forward speed of furrow opening increases, the shoveling rate increases while accelerating the vibration of the discharge pipe, further ensuring sufficient soil backfill to cover the planting groove and reducing the disturbance to the already compacted soil on both sides of the planting furrow during the secondary compaction, improving the reliability of the use of this rotary seeding and furrow opening machine.

Detailed implementation manners

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1, please refer to Figures 1 - 5A rotary sowing and furrowing integrated machine, comprising a first frame 1, the first frame 1 is installed on the walking mechanism of the rotary sowing and furrowing integrated machine through a connecting mechanism, one end of the first frame 1 is connected to the second frame 2, a lifting mechanism for adjusting the height and angle of the second frame 2 is arranged between the first frame 1 and the second frame 2, a rotary tillage knife group 9 is arranged at the bottom of the first frame 1, the rotary tillage knife group 9 includes two rotary tillage knife shafts, and the shaft body of the rotary tillage knife shaft is fixedly provided with a plurality of rotary tillage blades, and one side of the first frame 1 is provided A rotary tillage gear box 10 is provided for driving the rotary tillage knife group 9 to move. The rotary tillage gear box 10 can drive the two rotary tillage knife shafts to rotate through two output shafts respectively. When the rotary seeding and furrowing machine moves forward, the field ridges are rotary tilled. A pressing roller group 6 is provided at the bottom of the No. 2 frame 2. The pressing roller group 6 includes a No. 1 pressing roller 601 and a No. 2 pressing roller 602. The bottom of the No. 2 frame 2 is rotatably provided with two transmission shafts 18 for driving the No. 1 pressing roller 601 and the No. 2 pressing roller 602 to rotate.

[0035] A pressing gear box 11 for driving the transmission shaft 18 to rotate is arranged on one side of the second frame 2. The pressing gear box 11 is connected to the rotary tillage gear box 10 through a coupling mechanism. The rotary tillage gear box 10 can synchronously transmit power to the pressing gear box 11 through the coupling mechanism, so that the pressing gear box 11 can drive the first pressing roller 601 and the second pressing roller 602 to rotate respectively through the two transmission shafts 18. The rotation speeds of the first pressing roller 601 and the second pressing roller 602 are the same as those of the first pressing roller 601 and the second pressing roller 602. The traveling speed of the rotary seeding and furrowing machine is adapted, that is, when the traveling speed of the rotary seeding and furrowing machine increases, the rotation speeds of the rotary tillage shaft, the No. 1 pressing roller 601 and the No. 2 pressing roller 602 all increase synchronously, the No. 1 pressing roller 601 and the No. 2 pressing roller 602 press and level the top surface of the field ridge after rotary tillage, and a disc furrow opener 7 is fixedly arranged at the bottom of the No. 2 frame 2, the disc furrow opener is a double disc furrowing device, and the rear end of the double disc furrowing device is connected to the output pipe of the sowing mechanism.

[0036] The number of the disk furrow openers 7 is set to several and they are arranged evenly at intervals between the first pressing roller 601 and the second pressing roller 602. The arrangement direction of the disk furrow openers 7 is adapted to the axial direction of the pressing rollers. When the rotary seeding and furrowing machine travels, the first pressing roller 601 flattens the top surface of the ridge. During the forward movement, the furrowing disks of the disk furrow openers 7 dig the soil on the ridge to both sides and form planting grooves in the forward direction. The seeding mechanism controls the seeds to fall into the planting grooves. In this process, due to the increased density of the soil after being pressed, the space size between several disk furrow openers 7 increases after the soil plane is pressed, avoiding the disk furrow openers 7 from being congested by the excavated soil. The soil after one-time pressing is flat and has a large density. After furrowing, it is beneficial to the shaping of the formed planting grooves, improving the effect of planting and furrowing and ensuring the seeding quality. After seeding, the second pressing roller 602 travels for further pressing, covering the soil on the planting grooves. The secondary pressing is carried out on the basis of the first pressing and leveling, improving the leveling effect of the ridge.

[0037] On both sides of the first frame 1, there are notch disks 3 rotatably connected through bearings. The notch disks 3 are located at the front end of the rotary tiller blade group 9 in the forward direction. On both sides of the second frame 2, there are fixed bucket disks 4. The bucket disks 4 are located at the front of the pressing roller group 6 in the forward direction. During the furrowing process of the ditches on both sides of the ridge, the notch disks 3 carry out furrowing. The notch disks 3 are inclined. The inclination angle of the notch disks 3 is preferably 30 degrees. The excavated soil enters onto the ridge. The furrowing size of the notch disks 3 is smaller than that of the bucket disks 4. The bucket disks 4 repair and level the bottom and side soils of the ditches during the subsequent furrowing process and further expand the size of the ditches of the notch disks 3. The two machines for furrowing can effectively reduce the furrowing resistance. On both sides of the first pressing roller 601 and the second pressing roller 602, there are fixed pressing disks 5 sleeved. The pressing disks 5 are frustum-shaped. After the bucket disks 4 furrow again, the inclined sides of the pressing disks 5 squeeze the side walls of the ditches, further compacting the side walls of the ditches, and cooperating with the rolling pressing of the first pressing roller 601 to make the ridge extruded into shape. The second pressing wheels of the second pressing roller 602 carry out secondary pressing to prevent the ridge soil from scattering during the seeding and furrowing process and stabilize the ground.

[0038] Example 2, refer to Figures 3 - 8, on the basis of the first embodiment, a soil-dividing mechanism is provided on the first pressing roller 601. The number of soil-dividing mechanisms is set to several and is adapted to the number of disc furrow openers 7. The several soil-dividing mechanisms divide the first pressing roller 601 into several pressing roller units. Fixed sleeves of the several pressing roller units and the inner side of the second pressing roller 602 are fixedly sleeved with fixing plates 19. The fixing plates 19 are fixedly connected to the corresponding transmission shafts 18. The soil-dividing mechanism includes two soil retaining discs 12. The soil retaining discs 12 are annular and the bottom height is adapted to the furrowing depth of the disc furrow opener 7. The distance between the two soil retaining discs 12 is adapted to the furrowing width of the corresponding disc furrow opener 7. One side of the two soil retaining discs 12 is respectively fixedly connected to two adjacent pressing roller units. The transmission shaft 18 rotates to drive the corresponding fixing plate 19 to rotate. The fixing plate 19 in the first pressing roller 601 drives the corresponding pressing roller unit to roll. The second pressing roller 602 is driven to rotate by the corresponding fixing plate 19. The rotation of the pressing roller unit drives the soil retaining disc 12 to rotate, so that the pressing roller unit presses the corresponding ridge area, and the soil retaining disc 12 prevents the soil in the pressing area from squeezing the area between two adjacent pressing roller units. After the first pressing roller 601 presses, the soil in the furrowing area of the disc furrow opener 7 is loose, and the soil between two adjacent disc furrow openers 7 is leveled and compacted. Thus, while ensuring the pressing effect at one time, the compactness of the soil acting on the disc furrow opener 7 is reduced. While ensuring the shaping effect of the planting groove and the sufficient stacking space for soil, the furrowing resistance of the disc furrow opener 7 is further reduced, and the wear speed of the disc furrow opener 7 is reduced.

[0039] The soil-dividing device further includes a connecting plate 14. The top of the connecting plate 14 is fixedly connected to the second frame 2. The bottom of the connecting plate 14 is fixedly connected with a support seat 17. The support seat 17 is integrally annular, and the cross-section of the support seat 17 is in a U shape. The transmission shaft 18 can rotate relative to the support seat 17. One side of the support seat 17 is rotatably connected with a rotating ring plate 33 through a bearing. One end of the inner side of the rotating ring plate 33 is fixedly sleeved with an internal gear ring 22. A transmission gear 20 is fixedly sleeved at the position corresponding to the internal gear ring 22 on the transmission shaft 18. Refer to Figure 7 , one side of the support seat 17 is fixedly connected with a connecting rod 32. One end of the connecting rod 32 is rotatably connected with a connecting gear 21 through a bearing. Both the internal gear ring 22 and the transmission gear 20 are meshed with the connecting gear 21. The rotation direction of the transmission shaft 18 is adapted to the traveling direction of the pressing roller group 6, that is, the rolling forward direction of the pressing roller is consistent with its own forward direction.

[0040] The rotation of the transmission shaft 18 drives the rotation of the transmission gear 20. The rotation of the transmission gear 20 drives the rotation of the connecting gear 21. The rotation of the connecting gear 21 drives the rotation of the internal gear ring 22, thereby driving the rotation of the rotating ring plate 33. The rotation direction of the rotating ring plate 33 is opposite to that of the transmission shaft 18. A fixed soil-shoveling plate 15 is fixedly connected to the outer side of the rotating ring plate 33. The number of the fixed soil-shoveling plates 15 is set to be several. Connecting grooves 26 are formed at positions between adjacent two fixed soil-shoveling plates 15 on the arc surface of the rotating ring plate 33. A retaining soil ring 16 for closing the connecting groove 26 is fixedly connected to one side of the support seat 17. The outer wall of the retaining soil ring 16 is in close contact with the inner wall of the rotating ring plate 33 to close the connecting groove 26. The top thickness of the retaining soil ring 16 is increased and a discharge groove 31 communicating with the connecting groove 26 is formed. A discharge pipe 13 communicating with the discharge groove 31 is arranged at the top of the support seat 17. The discharge pipe 13 is inclined and the outlet of the discharge pipe 13 is located on one side of the corresponding disc furrow opener 7. The rotation of the rotating ring plate 33 drives the rotation of the fixed soil-shoveling plate 15. The soil-shoveling depth of the fixed soil-shoveling plate 15 is adapted to the rolling pressure depth of the first pressure roller 601.

[0041] The fixed soil-shoveling plate 15 shovels up the soil higher than the leveling height. The fixed soil-shoveling plate 15 and the rotating ring plate 33 cooperate to drive the shoveled soil to rotate to the top. Under the action of gravity, the soil falls into the lower discharge groove 31 through the connecting groove 26. The discharge groove 31 is inclined in the direction of the discharge pipe 13. The soil is discharged from the outlet after passing through the discharge pipe 13, and thus falls into the planted trench filled with seeds, ensuring sufficient soil for subsequent secondary pressure and soil covering, reducing the secondary disturbance to the soil on both sides of the planted trench, ensuring the planting depth of the seeds, and at the same time ensuring the flatness of the ridge top surface after the rolling pressure of the first pressure roller 601, further reducing the volume of the soil accumulated when the disc furrow opener 7 excavates the planted trench, and avoiding the congestion of the disc furrow opener 7.

[0042] Embodiment 3, refer to Figures 3 - 7 , on the basis of Embodiment 2, refer to Figure 5, a telescopic mechanism 8 is provided on one side of the fixed earth-removing plate 15, and a movable earth-removing plate 27 is provided on the earth-carrying side of the fixed earth-removing plate 15. The telescopic mechanism 8 is used to drive the movable earth-removing plate 27 to expand and contract. The length of the movable earth-removing plate 27 in the radial direction of the rotating ring plate 33 is less than that of the fixed earth-removing plate 15, and the movable earth-removing plate 27 will not contact the support seat 17 when expanding and contracting. Specifically, the telescopic mechanism 8 includes a fixed block 801, a telescopic rod 802 is slidably connected in the fixed block 801. One end of the telescopic rod 802 is T-shaped, so that the telescopic rod 802 can slide relative to the fixed block 801 without detaching from the fixed block 801. A return spring 803 for driving the telescopic rod 802 to extend out of the fixed block 801 is movably sleeved in the fixed block 801. One end of the telescopic rod 802 is L-shaped and fixedly connected to the movable earth-removing plate 27. The telescopic rod 802 is used to drive the movable earth-removing plate 27 to slide. A baffle 28 is fixedly connected to the outside of the support seat 17, and a guide plate 29 is fixedly connected to one side of the baffle 28. The baffle 28 and the guide plate 29 are integrally formed, and the guide plate 29 is inclined.

[0043] When the movable earth-removing plate 27 extends out of the fixed earth-removing plate 15, the earth-removing width of the soil-dividing mechanism is adapted to the distance between two adjacent rolling units. When the movable earth-removing plate 27 rotates to contact the guide plate 29, the inclined surface of the guide plate 29 pushes the movable earth-removing plate 27 to contract toward the fixed earth-removing plate 15. When the movable earth-removing plate 27 moves to contact the baffle 28, the movable earth-removing plate 27 completes the contraction. At this time, the return spring 803 is compressed, and the movable earth-removing plate 27 scrapes off the soil on the fixed earth-removing plate 15, ensuring the earth-removing width of the soil-dividing mechanism and improving the discharging effect. The baffle 28 and the matching soil retaining disc 12 hermetically connect the two sides of the connecting groove 26 to prevent material leakage. The discharge pipe 13 is rotatably connected to the support seat 17. Refer to Figure 5 , an activity groove 25 for the activity of the discharge pipe 13 is opened on one side of the support seat 17. A part of the pipe body of the discharge pipe 13 is located in the activity groove 25. A spring seat 24 is fixedly connected to the bottom of the activity groove 25. An adjusting spring 23 is fixedly connected to the top of the spring seat 24. One end of the adjusting spring 23 is fixedly connected to the discharge pipe 13. An adjusting plate 30 is fixedly connected to one side of the baffle 28. The adjusting plate 30 is inclined.

[0044] After the movable shovel plate 27 discharges materials, one side of the movable shovel plate 27 abuts against the inclined surface of the adjustment plate 30, and the movable shovel plate 27 rotates and gradually extends under the action of the reset spring 803. The movable shovel plate 27 rotates and abuts against the discharge pipe 13 and drives the discharge pipe 13 to rotate until it is out of contact with the discharge pipe 13. The adjustment spring 23 pushes the discharge pipe 13 to reset. Several movable shovel plates 27 cyclically contact the discharge pipe 13, so that the discharge pipe 13 reciprocates to ensure the discharge rate of the discharge pipe 13, and the rotation speed of the rotating ring plate 33 increases with the The rotary tillage gearbox 10 is connected to the gearbox of the traveling mechanism through a coupling mechanism as the speed of the rotary sowing and furrowing machine increases. The soil-shoveling rate of the soil-dividing mechanism increases, and the frequency of the circulation of several movable shoveling plates 27 in contact with the discharge pipe 13 increases, thereby increasing the discharge rate and the matching degree between the discharge rate of the discharge pipe 13 and the furrowing speed of the disc furrow opener 7, thereby further ensuring that the planting furrow always has sufficient backfill soil when the speed of the rotary sowing and furrowing machine changes.

[0045] Example 4, see Figures 9 - 11 , which is different from the soil dividing mechanism in the second embodiment, a plurality of seed pressing wheels 34 for opening the sowing furrow are fixedly sleeved on the outer side of the No. 1 pressing roller 601, and the plurality of seed pressing wheels 34 are arranged at even intervals, and the width of the seed pressing wheels 34 is adapted to the width of the sowing furrow required for sowing, and a plurality of sowing tubes 39 are fixedly connected to the middle position of the inner side of the No. 2 frame 2, and the positions and numbers of the sowing tubes 39 correspond to the positions and numbers of the seed pressing wheels 34, respectively, and a loosening roller 35 is rotatably connected to the inner side of the No. 2 frame 2 near the bottom, and a loosening roller 35 is fixedly arranged on one side of the No. 2 frame 2 The soil gear box 36, the loosening roller 35 and the second pressing roller 602 are connected through the loosening gear box 36. The rotation of the second pressing roller 602 can drive the loosening roller 35 to rotate. The roller body of the loosening roller 35 is fixedly connected with a plurality of knife seats 37. The plurality of knife seats 37 are staggered in a uniformly spaced manner in the axial direction of the loosening roller 35. A tool 38 is fixedly connected to one side of the knife seat 37 by bolts. The bottom end height of the rotation radius of the tool 38 is higher than the bottom height of the groove of the seed pressing wheel 34. The tool 38 is used to rotate and break the soil on the top of the seed after sowing and pressing.

[0046] When in use, the No. 1 pressing roller 601 rotates to drive the seed pressing wheel 34 to rotate. The No. 1 pressing roller 601 presses and flattens the soil between the sowing furrows. The radius of the seed pressing wheel 34 is larger than the radius of the No. 1 pressing roller 601. The seed pressing wheel 34 rolls the soil after rotary tillage to form the sowing furrow. The pressing effect of the No. 1 pressing roller 601 is used to ensure the compactness of the soil on both sides of the sowing furrow to avoid collapse. After the sowing groove is formed, the top of the sowing tube 39 is connected to the seed spreader of the sowing mechanism. The sowing mechanism fills the seeds into the sowing furrow through the sowing tube 39. The diameter of the sowing tube 39 is adapted to the width of the seed pressing wheel 34 to ensure the distribution width of the seeds.

[0047] After sowing is completed, the second compaction roller 602 compacts the soil for the second time, covering the seeds with the compacted soil. The second compaction roller 602 drives the soil loosening roller 35 to rotate. The soil loosening roller 35 drives the tool holder 37 to rotate, and the tool holder 37 drives the tool 38 to rotate. The tool 38 is in an overall "7" shape. When the tool 38 rotates, it loosens the soil covering the top of the seeds, eliminates the cracks generated on the ridge during the second compaction by the second compaction roller 602, and at the same time avoids the excessive compaction of the soil on the top of the seeds during the compaction process, which may lead to a reduction in the germination rate of the seeds. By loosening the soil on the top of the seeds for the second time with the tool 38, it ensures that the soil near the seeds is hard at the bottom and soft at the top, and air can contact the seeds through the gaps in the loosened soil, thus improving the germination rate of the seeds.

[0048] The usage method (working principle) of the present invention is as follows:

[0049] When the rotary seeding and ditching machine travels, the notch discs 3 on both sides open ditches for the ridge. The digging bucket discs 4 cooperate with the compaction discs 5 to compact the side walls of the ditches during the subsequent ditching process, and cooperate with the compaction roller group 6 to ensure the flatness of the side walls and the top surface of the ridge. The rotary tiller knife group 9 tills the ridge formed after the notch discs 3 excavate. Several compaction roller units in the first compaction roller 601 compact the tilled soil for the first time, ensuring the compactness of the soil between the subsequent disc openers 7, which is beneficial to the stability and flatness of the side walls of the planting ditches and avoids soil congestion between the disc openers 7. The fixed soil shoveling plates 15 and the movable soil shoveling plates 27 between the compaction roller units cooperate to rotate and shovel the soil. The disc openers 7 open planting ditches on the leveled soil surface after the first compaction roller 601 levels and the soil shoveling plates excavate. The seeding mechanism drops the seeds into the planting ditches. The excavated soil by the disc openers 7 is loose while the two sides are dense, ensuring the ditching effect of the planting ditches and reducing the resistance of ditching.

[0050] After the soil is shoveled and transported to the top of the rotating ring plate 33, it passes through the connecting groove 26 and the discharge groove 31 and is discharged from the discharge pipe 13 into the planting ditches opened by the disc openers 7 for primary soil covering, ensuring the amount of subsequent soil covering and the burial depth of the seeds. During the rotation, the movable soil shoveling plate 27 cooperates with the telescopic mechanism 8 to drive the discharge pipe 13 to vibrate cyclically. Moreover, the rotating ring plate 33 is in transmission connection with the transmission shaft 18, matching the vibration frequency with the forward speed of the traveling mechanism, so that the discharge rate of the discharge pipe 13 matches the forward speed of the disc openers 7, further ensuring the depth of soil covering.
