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. The present invention uses a No. 1 pressing roller in cooperation with a soil retaining plate to perform a pressing operation before the disc furrow opener 7 opens the furrow, thereby increasing the soil density outside the area where the top of the field ridge needs to be opened as a planting furrow, so that the soil on both sides of the disc is not easy to collapse during the subsequent furrowing of the planting furrow, which is convenient for the shaping of the planting furrow and the soil is leveled, thereby improving the furrowing effect of the planting furrow. After the soil is compacted, the space on both sides of the disc furrow opener is increased to avoid congestion caused by accumulation of soil between adjacent disc furrow openers and reduce the resistance during the furrowing of the planting furrow. At the same time, the notched plate and the bucket plate open the furrows twice to further reduce the resistance of the rotary seeding and furrowing integrated machine. After the bucket plate opens the furrows, the pressing plates on both sides of the pressing roller group are used to level the side walls of the field ridges to ensure the shaping effect of the furrows, as well as the secondary pressing of the No. 2 pressing roller to ensure that the field ridges of the disc furrow opener will not fall apart during the planting furrowing process, thereby improving the stability of the field ridges.

[0020] 2. The present invention drives the rotating ring plate to rotate in the opposite direction through the synchronous transmission of the transmission shaft, so that the movable shovel plate and the fixed shovel plate cooperate to shovel the soil between the adjacent pressing roller units, so that the soil behind the No. 1 pressing roller remains flat, and the soil acted on by the disc opener is loose soil, which does not increase the opening resistance of the disc opener and reduces the soil volume generated when the planting groove is opened, further avoiding soil congestion between the disc openers. At the same time, the excavated soil is transported from the discharge pipe to the planting groove after the seeds are filled, ensuring that there is enough soil to be backfilled into the planting groove later to ensure the burial depth of the seeds, and the movable shovel plate drives the discharge pipe to vibrate in turn, so that the vibration frequency of the discharge pipe increases with the increase of the transmission shaft speed, that is, when the forward speed of trenching increases, the shoveling rate increases and the vibration of the discharge pipe is accelerated, further ensuring that sufficient soil is backfilled to cover the planting groove, and reducing the disturbance of the compacted soil on both sides of the planting groove during the secondary suppression, thereby improving the reliability of the rotary seeding and furrowing integrated machine.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] For example, see Figure 1-Figure 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 disc furrow openers 7 is set to be several and they are evenly spaced and arranged between the No. 1 pressing roller 601 and the No. 2 pressing roller 602. The arrangement direction of the disc furrow openers 7 is adapted to the axial direction of the pressing roller. When the rotary seeding and furrowing integrated machine is moving, the No. 1 pressing roller 601 flattens the top surface of the field ridge, and the furrowing discs of the disc furrow opener 7 dig the soil on the field ridge to both sides during the forward process and form planting grooves in the forward direction. The sowing mechanism controls the seeds to fall into the planting grooves. In this process, since the soil is flattened, The density after pressing increases. After the soil plane is pressed, the space between several disc openers 7 increases to avoid congestion of the disc openers 7 with the excavated soil. The soil after one pressing is flat and dense, which is conducive to the shaping of the planting grooves after ditching, improves the effect of planting ditching, and ensures the quality of sowing. After sowing, the No. 2 pressing roller 602 moves forward and presses again to cover the soil on the planting grooves. The second pressing is carried out on the basis of the first pressing and leveling to improve the leveling effect of the field ridges.

[0037] Both sides of the No. 1 frame 1 are rotatably connected with a notched disk 3 through a bearing, and the notched disk 3 is located at the front end of the rotary tillage blade group 9 in the forward direction. Both sides of the No. 2 frame 2 are fixedly connected with a bucket disk 4, and the bucket disk 4 is located at the front degree of the pressing roller group 6 in the forward direction. In the process of ditching the furrows on both sides of the field ridge, the notched disk 3 is used for ditching. The notched disk 3 is inclined, and the inclination angle of the notched disk 3 is preferably 30 degrees. The excavated soil enters the field ridge, and the ditching size of the notched disk 3 is smaller than the ditching size of the bucket disk 4. The bucket disk 4 will dig the bottom surface and The side soil is repaired and leveled, and the size of the ridge of the notched plate 3 is further expanded. The two machines dig ditching, which can effectively reduce the ditching resistance. Both sides of the No. 1 pressing roller 601 and the No. 2 pressing roller 602 are fixedly sleeved with pressing plates 5, and the pressing plates 5 are frustum-shaped. After the bucket plate 4 digs the ditch again, the inclined side of the pressing plate 5 squeezes the side wall of the ditch to further compact the side wall of the ditch, and cooperates with the rolling pressing of the No. 1 pressing roller 601 to squeeze the field ridge into shape, and the second pressing wheel of the No. 2 pressing roller 602 performs secondary pressing to prevent the field ridge soil from falling off during the sowing and digging process and stabilize the ground.

[0038] Example 2, see Figure 3-Figure 8, on the basis of the first embodiment, a soil separating mechanism is provided on the first pressing roller 601. The number of the soil separating mechanisms is set to be several and is adapted to the number of the disc furrow openers 7. The several soil separating 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 with the corresponding transmission shafts 18. The soil separating 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 sides of the two soil retaining discs 12 are respectively fixedly connected with two adjacent pressing roller units. The rotation of the transmission shaft 18 drives 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. Therefore, while ensuring the pressing effect at one time, the compactness of the soil acted on by 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 separating device further includes a connecting plate 14. The top of the connecting plate 14 is fixedly connected with 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 engaged 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 transmission shaft 18 rotates to drive the transmission gear 20, the transmission gear 20 rotates to drive the connecting gear 21, the connecting gear 21 rotates to drive the inner gear ring 22, thereby driving the rotating ring plate 33 to rotate, and the rotation direction of the rotating ring plate 33 is opposite to the rotation direction of the transmission shaft 18. The outer side of the rotating ring plate 33 is fixedly connected with a fixed shovel plate 15, and the number of fixed shovel plates 15 is set to be several. The arc surface of the rotating ring plate 33 is located between two adjacent fixed shovel plates 15. A connecting groove 26 is opened, and one side of the support seat 17 is fixedly connected with A retaining ring 16 is used to close the connecting groove 26, and the outer wall of the retaining ring 16 fits with the inner wall of the rotating ring plate 33 to close the connecting groove 26. The top thickness of the retaining ring 16 is increased and a discharge groove 31 connected to the connecting groove 26 is opened. A discharge pipe 13 connected to the discharge groove 31 is set on 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 fixed shovel plate 15 to rotate, and the shoveling depth of the fixed shovel plate 15 is adapted to the pressing depth of the No. 1 pressing roller 601.

[0041] The fixed shovel plate 15 scoops up the soil that is higher than the leveling height, and the fixed shovel plate 15 cooperates with the rotating ring plate 33 to drive the scooped soil to rotate to the top. Under the action of gravity, the soil falls into the discharge trough 31 below through the connecting groove 26. The discharge trough 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 then falls into the planting groove filled with seeds, ensuring that there is sufficient soil for the subsequent secondary compaction and covering, reducing the secondary disturbance of the soil on both sides of the planting groove, ensuring the planting depth of the seeds, and at the same time ensuring the flatness of the top surface of the field ridge after the No. 1 compaction roller 601 rolls and compacts, further reducing the volume of soil accumulated when the disc opener 7 digs the planting groove, and avoiding congestion of the disc opener 7.

[0042] Example 3, see Figure 3-Figure 7 Based on the second embodiment, refer to Figure 5A telescopic mechanism 8 is provided on one side of the fixed shovel blade 15, and a movable shovel blade 27 is provided on the soil-carrying side of the fixed shovel blade 15. The telescopic mechanism 8 is used to drive the movable shovel blade 27 to extend and retract. The length of the movable shovel blade 27 in the radial direction of the rotating ring plate 33 is smaller than that of the fixed shovel blade 15. When the movable shovel blade 27 is extended and retracted, it will not contact the support seat 17. Specifically, the telescopic mechanism 8 includes a fixed block 801, and 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 It can slide relative to the fixed block 801 without separating from the fixed block 801. A movable sleeve in the fixed block 801 is provided with a return spring 803 for driving the telescopic rod 802 to extend out of the fixed block 801. One end of the telescopic rod 802 is L-shaped and fixedly connected to the movable earth-moving plate 27. The telescopic rod 802 is used to drive the movable earth-moving plate 27 to slide. A baffle plate 28 is fixedly connected to the outer side of the support seat 17, and a guide plate 29 is fixedly connected to one side of the baffle plate 28. The baffle plate 28 and the guide plate 29 are made of one piece, and the guide plate 29 is arranged at an angle.

[0043] The movable shovel plate 27 extends out of the fixed shovel plate 15 so that the shoveling width of the soil-dividing mechanism is adapted to the spacing between the two adjacent pressure roller units. When the movable shovel plate 27 rotates to contact the guide plate 29, the inclined surface of the guide plate 29 pushes the movable shovel plate 27 to retract toward the side of the fixed shovel plate 15. When the movable shovel plate 27 moves to contact the baffle plate 28, the movable shovel plate 27 completes the retraction. At this time, the return spring 803 is compressed, and the movable shovel plate 27 drops the soil on the fixed shovel plate 15 to ensure the shoveling width of the soil-dividing mechanism and improve the discharge effect. The baffle plate 28 and the matching retaining plate 12 close the two sides of the connecting groove 26 to avoid leakage. The discharge pipe 13 is rotatably connected to the support seat 17, see Figure 5 A movable groove 25 for the movement of the discharge pipe 13 is provided on one side of the support seat 17, and part of the tube body of the discharge pipe 13 is located in the movable groove 25. A spring seat 24 is fixedly connected to the bottom of the movable groove 25, and 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, and the adjusting plate 30 is arranged at an angle.

[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 Figure 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 No. 2 pressing roller 602 performs secondary pressing to compact the soil and cover the top of the seeds. The No. 2 pressing roller 602 drives the loosening roller 35 to rotate, the loosening roller 35 drives the knife holder 37 to rotate, the knife holder 37 drives the cutter 38 to rotate, and the cutter 38 is in the shape of a "7" as a whole. The cutter 38 rotates to loosen the soil covering the top of the seeds, eliminating the cracks on the ridges caused by the secondary pressing of the No. 2 pressing roller 602, and at the same time avoiding excessive compaction of the soil on the top of the seeds during the pressing process, which leads to a decrease in the germination rate of the seeds. The soil on the top of the seeds is broken up for the second time by the cutter 38 to ensure that the soil near the seeds is hard at the bottom and soft at the top, so that the air can contact the seeds through the gaps in the scattered soil, thereby improving the germination rate of the seeds.

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

[0049] When the rotary seeding and furrowing machine is moving, the notched discs 3 on both sides dig furrows, the bucket disc 4 cooperates with the pressure disc 5 to compact the side walls of the furrows in the subsequent furrowing process, and cooperates with the pressure roller group 6 to ensure the flatness of the side walls and top surfaces of the ridges, the rotary tillage blade group 9 performs rotary tillage on the ridges formed after the notched disc 3 is excavated, and several pressure roller units in the No. 1 pressure roller 601 press the soil after rotary tillage to ensure the density of the soil between the subsequent disc furrow openers 7, which is beneficial In order to make the side wall of the planting ditch stable and flat and avoid soil congestion between the disc openers 7, the fixed shovel board 15 and the movable shovel board 27 between the pressing roller units cooperate to rotate to shovel up the soil, and the disc opener 7 digs the planting ditch for the leveled soil surface after the No. 1 pressing roller 601 levels and the shovel board excavates, and the sowing mechanism drops the seeds into the planting ditch. The excavated soil of the disc opener 7 is loose and dense on both sides, which ensures the digging effect of the planting ditch and reduces the resistance of digging.

[0050] After the soil is scooped up and transported to the top of the rotating ring plate 33, it is discharged from the discharge pipe 13 into the planting furrow opened by the disc opener 7 through the connecting groove 26 and the discharge groove 31, and the planting furrow is covered with soil for the first time to ensure the amount of subsequent covering soil and the burial depth of the seeds. During the rotation process, the movable shovel plate 27 cooperates with the telescopic mechanism 8 to circulate and drive the discharge pipe 13 to vibrate, and the rotating ring plate 33 is connected to the transmission shaft 18 for transmission, so that the vibration frequency is matched with the forward speed of the walking mechanism, so that the discharge rate of the discharge pipe 13 is matched with the forward speed of the disc opener 7, and the depth of the covering soil is further guaranteed.
