[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] The purpose of this invention is to provide a corn-soybean combined harvesting device that can harvest corn and soybeans quickly and efficiently at the same time, thus increasing its adaptability.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] As shown in Figures 1-11, this embodiment provides a corn-soybean composite harvesting device 100, including a frame 1, a corn harvesting mechanism, a soybean harvesting mechanism, a corn aggregation and conveying mechanism, a soybean aggregation and conveying mechanism, and a power mechanism. The corn harvesting mechanism is located above and in front of the soybean harvesting mechanism. In this embodiment, the soybean harvesting mechanism is horizontally arranged, while the corn harvesting mechanism is inclined downwards from back to front. The corn harvesting mechanism includes multiple corn dividers 6, multiple corn harvesting components, and multiple corn cutters 10. The multiple corn harvesting components are sequentially arranged on the frame 1. Specifically, the multiple corn harvesting components are arranged sequentially from left to right. A corn divider 6 mounted on the frame 1 is arranged above any two adjacent corn harvesting components, and a corn cutter 10 mounted on the frame 1 is arranged below any two adjacent corn harvesting components. The corn aggregation and conveying mechanism is mounted on the frame 1 and located behind the multiple corn harvesting components. The power mechanism is used to power the corn harvesting components, corn cutters 10, and corn aggregation and conveying mechanism. The transmission mechanism provides power; the soybean harvesting mechanism includes soybean cutting teeth 15, multiple soybean dividers 11, and multiple soybean harvesting components. The multiple soybean harvesting components are arranged sequentially on the frame 1. Specifically, the multiple soybean harvesting components are arranged sequentially from left to right. A soybean divider 11 mounted on the frame 1 is arranged above any two adjacent soybean harvesting components. The soybean cutting teeth 15 are mounted on the frame 1 and located below the multiple soybean harvesting components. The soybean aggregation and transmission mechanism is mounted on the frame 1 and located behind the multiple soybean harvesting components. The power mechanism is used to provide power to the soybean harvesting components and the soybean aggregation and transmission mechanism.

[0034] In this embodiment, for areas where corn and soybeans are planted simultaneously, a double-layer harvesting method is adopted by utilizing the height difference between corn and soybeans. This allows for the rapid and efficient harvesting of both corn and soybeans at the same time. In addition, areas where corn or soybeans are planted separately can also be harvested, meaning that corn or soybeans can be harvested independently. This increases the range of applications and solves the problem of the current lack of corn-soybean intercropping harvesting technology on the market.

[0035] Specifically, the power mechanism includes a power component 61, a first transmission assembly, a corn transmission rod 2, and a soybean transmission rod 3. Both ends of the corn transmission rod 2 are rotatably mounted on the frame 1 and located behind multiple corn harvesting assemblies. Both ends of the soybean transmission rod 3 are rotatably mounted on the frame 1 and located behind multiple soybean harvesting assemblies. The power component 61 is used to connect to an external power source. The power component 61 provides power to the corn transmission rod 2 and the soybean transmission rod 3 through the first transmission assembly. The corn transmission rod 2 provides power to the corn harvesting assembly and the corn cutter 10, and the soybean transmission rod 3 provides power to the soybean harvesting assembly.

[0036] In this specific embodiment, the power component 61 is a motor. The first transmission assembly includes a first chain 4, a second chain 5, two first sprockets, and two second sprockets. The two first sprockets are respectively mounted on the power output shaft of the motor and one end of the corn transmission rod 2. The first chain 4 is wound around the two first sprockets. The two second sprockets are respectively mounted on one end of the corn transmission rod 2 and one end of the soybean transmission rod 3. The second chain 5 is wound around the two second sprockets. During operation, the motor drives the corn transmission rod 2 to rotate via the first chain 4, and then drives the soybean transmission rod 3 to rotate via the second chain 5. That is, the motor provides power to the corn transmission rod 2 and the soybean transmission rod 3.

[0037] As shown in Figures 4 and 5, the corn harvesting assembly includes a corn header drive box, two corn picking rollers 9 arranged side by side, two corn reelers 8 arranged side by side, and two corn reeling chains 7 arranged side by side. The corn header drive box and the corn reelers 8 are both mounted on the frame 1. The corn drive rod 2 is connected to the corn header drive box. The two first corn power output shafts at the front end of the corn header drive box are respectively connected to the rear ends of the two corn picking rollers 9. The front ends of the two corn picking rollers 9 are rotatably mounted on the frame 1, and the two corn picking rollers 9 rotate in opposite directions. The two corn picking rollers 9 are used to apply a downward force to the corn stalks. Each corn picking roller 9 is located below a corn reeler 8. Specifically, the front ends of the corn picking rollers 9 are rotatably mounted on the frame 1 through a first bearing, and the first bearing is mounted on the frame 1 through a first bearing seat. A first corn reeling star wheel 20 is fixedly fitted on each of the two second corn power output shafts 19 at the lower end of the corn header transmission box. A corn star wheel shaft 21 is installed on the upper part of the front end of each corn reeler 8. A second corn reeling star wheel 22 is rotatably installed on each corn star wheel shaft 21. Each corn reeling chain 7 is wound around a first corn reeling star wheel 20 and a second corn reeling star wheel 22, and the two corn reeling chains 7 rotate in opposite directions. In this embodiment, the corn divider 6, corn reeler 8, corn reeling chain 7, corn ear picking roller 9, and corn cutter 10 are all inclined downward from back to front. The two corn reeling chains 7 are used to apply upward and backward forces to the corn stalks.

[0038] In this embodiment, the first corn power output shaft of the corn header transmission box is perpendicular to the second corn power output shaft 19. During operation, the corn transmission rod 2 drives the two corn picking rollers 9 and the two corn reeling chains 7 to work simultaneously through the corn header transmission box. By using the corn header transmission box, the reeling speed and the ear picking speed can be increased independently, thereby improving the efficiency of reeling and ear picking.

[0039] The corn harvesting assembly also includes two tensioning components corresponding to the corn reeling chain 7. Each tensioning component includes a first connecting plate 23, a second connecting plate 24, a clamping rod 25, a middle block 26, a stud 27, an adjusting nut 28, and a clamping spring 29. One end of the first connecting plate 23 is rotatably mounted on a second corn power output shaft 19 of the corn header transmission box. The other end of the first connecting plate 23 is connected to the stud 27. The clamping spring 29 is mounted on the stud 27, and the adjusting nut 28 is installed on the stud 27. 7 is located between the compression spring 29 and the first connecting plate 23; one end of the second connecting plate 24 is rotatably sleeved on the corn star wheel shaft 21, and the other end of the second connecting plate 24 is connected to the compression rod 25; the two ends of the intermediate block 26 are respectively provided with a first receiving groove and a second receiving groove, the end of the stud 27 away from the first connecting plate 23 can extend into the first receiving groove and abut against the intermediate block 26, and the end of the compression rod 25 away from the second connecting plate 24 can extend into the second receiving groove and abut against the intermediate block 26.

[0040] In this embodiment, the position of the corn star wheel shaft 21 remains unchanged, while the second corn power output shaft 19 extending from the corn header transmission box can make slight movements. When the adjusting nut 28 is turned to move it toward the middle block 26, the distance between the ends of the first connecting plate 23 and the second connecting plate 24 increases under the action of the compression spring 29, thereby increasing the distance between the second corn power output shaft 19 and the corn star wheel shaft 21 of the corn header transmission box, and thus achieving tensioning of the corn reeling chain 7. The corn harvesting mechanism adopts non-row harvesting, and in conjunction with the corn divider 6 and the corn reeling device 8, it adapts to most planting intervals.

[0041] The corn harvesting mechanism also includes multiple drive shafts 30 corresponding to the corn cutters 10. Multiple first bevel gears 31 are mounted on the corn drive rod 2. The drive shafts 30 are rotatably mounted on the frame 1, and their axial direction is perpendicular to the axial direction of the corn drive rod 2. Second bevel gears 32 and third bevel gears 33 are fixedly sleeved at both ends of the drive shafts 30, respectively. The second bevel gears 32 mesh with the first bevel gears 31. The corn cutter 10 includes a cutter shaft and a cutter body located below the cutter shaft. The cutter shaft is rotatably mounted on the frame 1, and a fourth bevel gear 34 meshing with the third bevel gear 33 is fixedly sleeved on its upper part. During operation, the corn drive shaft 30 drives the drive shaft 30 to rotate via the first bevel gears 31 and the second bevel gears 32. The drive shaft 30, in turn, drives the cutter shaft and cutter body to rotate via the third bevel gears 33 and the fourth bevel gear 34.

[0042] When harvesting corn, the corn divider 6 between the two corn harvesting components separates the corn stalks. The corn stalks are harvested in the gap between the two corn picking rollers 9 of the corn harvesting components. The two corn picking chains 7 convey the corn stalks upward and backward. The two corn picking rollers 9 rotate symmetrically to send the corn stalks downward, thereby removing the corn cobs from the corn stalks and conveying them to the rear corn aggregation and transmission mechanism. The corn cutter 10 cuts the corn stalks it encounters.

[0043] As shown in Figures 6 and 7, the soybean harvesting assembly includes a soybean header drive box, two soybean picking rollers 14 arranged side by side, two soybean reelers 13 arranged side by side, and two soybean reeling chains 12 arranged side by side. The soybean header drive box and soybean reelers 13 are both mounted on the frame 1. The soybean drive rod 3 is connected to the soybean header drive box. The two first soybean power output shafts at the front end of the soybean header drive box are respectively connected to the rear ends of the two soybean picking rollers 14. The front ends of the two soybean picking rollers 14 are rotatably mounted on the frame 1, and the two soybean picking rollers 14 rotate in opposite directions. The two soybean picking rollers 14 are used to apply an upward force to the soybean stalks. Each soybean picking roller 14 is located below a soybean reeler 13. Specifically, the front ends of the soybean picking rollers 14 are rotatably mounted on the frame 1 through a second bearing, and the second bearing is mounted on the frame 1 through a second bearing seat. A first soybean reeling star wheel 36 is fixedly mounted on each of the two second soybean power output shafts 35 at the lower end of the soybean header transmission box. A soybean star wheel shaft 37 is installed on the upper part of the front end of each soybean reeler 13. A second soybean reeling star wheel 38 is rotatably mounted on each soybean star wheel shaft 37. Each soybean reeling chain 12 is wound around a first soybean reeling star wheel 36 and a second soybean reeling star wheel 38. The two soybean reeling chains 12 rotate in opposite directions and are used to apply a backward force to the soybean stalks.

[0044] In this embodiment, the first soybean power output shaft 35 of the soybean header transmission box is perpendicular to the second soybean power output shaft 35. During operation, the soybean transmission rod 3 drives the two soybean picking rollers 14 and the two soybean reeling chains 12 to work simultaneously through the soybean header transmission box. By using the soybean header transmission box, the reeling speed and picking speed can be increased independently, improving the efficiency of reeling and picking. The soybean harvesting mechanism adopts non-row harvesting, and with the help of the soybean divider 11 and soybean reeling device 13, it is adaptable to most planting intervals.

[0045] When harvesting soybeans, the soybean separator 11 between the two soybean harvesting components separates the soybeans. The soybeans are harvested in the gap between the two soybean picking rollers 14 of the soybean harvesting components. Two soybean reeling chains 12 convey the soybean stalks backward, and the two soybean picking rollers 14 rotate symmetrically to pull the soybean stalks upward. In conjunction with the soybean cutting teeth 15, the lower end of the soybean stalks is harvested, and the soybean stalks with soybean grains are then conveyed to the soybean aggregation and conveying mechanism at the rear. In this embodiment, the soybeans enter the soybean aggregation and conveying mechanism with minimal damage through chain clamping and conveying, combined with the soybean cutting teeth 15 below.

[0046] The power mechanism also includes a second transmission assembly, through which the power component 61 provides power to the corn polymerization transmission mechanism and the soybean polymerization transmission mechanism.

[0047] As shown in Figures 8 and 9, the corn aggregation and conveying mechanism includes a corn storage bin 39, a corn auger shaft 40, a first corn auger blade 41, a second corn auger blade 42, a corn baffle plate 43, and two movable corn frames. The two movable corn frames are adjustablely mounted on both sides of the frame 1. The two ends of the corn auger shaft 40 are rotatably mounted on the two movable corn frames. The first corn auger blade 41 and the second corn auger blade 42 are respectively mounted on both sides of the corn auger shaft 40, and the rotation directions of the first corn auger blade 41 and the second corn auger blade 42 are opposite. The power unit 61 provides power to the corn auger shaft 40 through the second transmission assembly. The corn storage bin 39 is set on the frame 1 and located below the corn auger shaft 40. A corn discharge port is set in the middle of the corn storage bin 39. The corn baffle plate 43 is set on the frame 1 and located above the area between the first corn auger blade 41 and the second corn auger blade 42.

[0048] During operation, the corn auger shaft 40 drives the first corn auger blade 41 and the second corn auger blade 42 to rotate. The corn cobs, driven by the first and second auger blades 41 and 42, converge towards the center of the corn collection bin 39, and are then discharged through the corn outlet. A significant speed is generated between the first and second auger blades 41 and 42. If the corn cobs have different speeds at the center, they may collide. A corn baffle 43 prevents crop and debris from splashing around.

[0049] As shown in Figure 11, the corn movable frame includes a corn movable plate 44 and a corn mounting block 45 disposed at the lower part of the corn movable plate 44. The corn mounting block 45 is provided with corn mounting holes. The two ends of the corn auger shaft 40 are respectively rotatably mounted in the two corn mounting holes through a third bearing 59. The corn aggregation and conveying mechanism also includes two corn adjustment components corresponding to the corn movable frame. The corn adjustment components include a corn fixing plate 46, a first locking component, a second locking component, and two corn adjustment bolts 47. The first locking component is used to lock the corn fixing plate 46 to the frame 1. The corn fixing plate 46 is provided with two first through holes, and the corn movable plate 44 is provided with two first threaded holes. Each corn adjustment bolt 47 passes through a first through hole and is installed in a first threaded hole. When it is necessary to adjust the position of the corn movable frame in the vertical direction, the head of the corn adjustment bolt 47 is pressed against the bottom surface of the corn fixing plate 46 and screwed. At this time, the corn adjustment bolt 47 rotates in place, thereby causing the corn movable plate 44 to move relative to the corn adjustment bolt 47 to adjust the distance between the corn movable plate 44 and the corn fixing plate 46. Then, the second locking component locks the corn movable plate 44 to the frame 1. At this point, the height adjustment of the corn movable frame and the corn auger shaft 40 installed on the corn movable frame is completed. After adjustment, the corn drive belt 57 wound on the output pulley 54 and the corn pulley 55 can be replaced according to the actual situation.

[0050] In this specific embodiment, the first locking assembly includes four first locking bolts 48. The four first locking bolts 48 are arranged in pairs, and the two pairs of first locking bolts 48 lock and fix the two sides of the corn fixing plate 46 respectively. Among them, the two first locking bolts 48 in one pair are located above and below the corn fixing plate 46 respectively, thereby locking the corn fixing plate 46 between the two first locking bolts 48.

[0051] In this specific embodiment, the second locking assembly includes four second locking bolts 49. The four second locking bolts 49 are arranged in pairs, and the two pairs of second locking bolts 49 respectively lock and fix both sides of the corn movable plate 44. Among them, two second locking bolts 49 in one pair are located above and below the corn movable plate 44, thereby locking the corn movable plate 44 between the two second locking bolts 49. The frame 1 is provided with a plurality of first screw holes for installing the first locking bolts 48, and a plurality of second screw holes for installing the second locking bolts 49.

[0052] As shown in Figures 8 and 9, the soybean aggregation and conveying mechanism includes a soybean storage bin 50, a soybean auger shaft 51, a first soybean auger blade 52, a second soybean auger blade 53, a soybean baffle plate, and two movable soybean frames. The two movable soybean frames are adjustablely mounted on both sides of the frame 1. The two ends of the soybean auger shaft 51 are rotatably mounted on the two movable soybean frames. The first soybean auger blade 52 and the second soybean auger blade 53 are respectively mounted on both sides of the soybean auger shaft 51, and the rotation directions of the first soybean auger blade 52 and the second soybean auger blade 53 are opposite. The power unit 61 provides power to the soybean auger shaft 51 through the second transmission assembly. The soybean storage bin 50 is set on the frame 1 and located below the soybean auger shaft 51. A soybean discharge port is set in the middle of the soybean storage bin 50. The soybean baffle plate is set on the frame 1 and located above the area between the first soybean auger blade 52 and the second soybean auger blade 53.

[0053] During operation, the soybean auger shaft 51 drives the first soybean auger blade 52 and the second soybean auger blade 53 to rotate. Under the influence of these blades, the soybeans converge towards the center of the soybean collection bin 50, and are then discharged through the soybean outlet. A significant speed is generated between the first soybean auger blade 52 and the second soybean auger blade 53. If the soybeans move at different speeds at the center, they may collide. A soybean baffle is installed to prevent the crop and debris from splashing around.

[0054] The soybean movable frame includes a soybean movable plate and a soybean mounting block disposed at the lower part of the soybean movable plate. The soybean mounting block is provided with soybean mounting holes. The two ends of the soybean auger shaft 51 are respectively rotatably mounted in the two soybean mounting holes through a fourth bearing 60. The soybean aggregation and conveying mechanism also includes two soybean adjustment components corresponding to the soybean movable frame. The soybean adjustment components include a soybean fixing plate, a first locking component, a second locking component, and two soybean adjustment bolts. The first locking component is used to lock and fix the soybean fixing plate to the frame 1. The soybean fixing plate is provided with two second through holes, and the soybean movable plate is provided with two second threaded holes. Each soybean adjustment bolt passes through a second through hole and is installed in a second threaded hole. When it is necessary to adjust the vertical position of the soybean movable frame, the head of the soybean adjustment bolt is tightened against the bottom surface of the soybean fixing plate. At this time, the soybean adjustment bolt rotates in place, thereby causing the soybean movable plate to move relative to the soybean adjustment bolt to adjust the distance between the soybean movable plate and the soybean fixing plate. Then, the soybean movable plate is locked and fixed to the frame 1 by the second locking component. At this point, the height adjustment of the soybean movable frame and the soybean auger shaft 51 installed on the soybean movable frame is completed. After adjustment, the soybean drive belt 58 wound on the output pulley 54 and the soybean pulley 56 can be replaced according to the actual situation.

[0055] In this specific embodiment, the third locking assembly includes four third locking bolts, which are arranged in pairs. The two sets of third locking bolts lock and fix the two sides of the soybean fixing plate respectively. In one set, two third locking bolts are located above and below the soybean fixing plate, thereby locking the soybean fixing plate between the two third locking bolts.

[0056] In this specific embodiment, the fourth locking assembly includes four fourth locking bolts, which are arranged in pairs. The two pairs of fourth locking bolts respectively lock and fix both sides of the soybean movable plate. In one pair, two fourth locking bolts are located above and below the soybean movable plate, thereby locking the soybean movable plate between the two fourth locking bolts. The frame 1 is provided with multiple third screw holes for installing third locking bolts, and multiple fourth screw holes for installing fourth locking bolts.

[0057] Specifically, the second transmission assembly includes an output pulley 54, a corn pulley 55, a soybean pulley 56, a corn drive belt 57, and a soybean drive belt 58.

The corn drive belt 57 is wound around the output pulley 54 and the corn pulley 55. The soybean pulley 56 is fixedly mounted on one end of the soybean auger shaft 51. The soybean drive belt 58 is wound around the output pulley 54 and the soybean pulley 56. During operation, the motor can drive the corn auger shaft 40 and the soybean auger shaft 51 to rotate via the corn drive belt 57 and the soybean drive belt 58.

[0058] As shown in Figure 3, this embodiment also includes a lifting device, which includes a first connecting rod 16, a second connecting rod 17, and a linear drive component 18. The first connecting rod 16 is vertically fixed to the rear of the frame 1, and the second connecting rod 17 is mounted on the machine body, which refers to the main body capable of driving the entire corn-soybean composite harvesting device 100. The front end of the second connecting rod 17 is hinged to the upper end of the first connecting rod 16, and both ends of the linear drive component 18 are hinged to the first connecting rod 16 and the second connecting rod 17, respectively. In this embodiment, two lifting devices are provided, and the linear drive component 18 is a hydraulic rod. During operation, the frame 1 is moved forward and upward or backward and downward by controlling the extension and retraction of the hydraulic rod, thus achieving the overall lifting and lowering of the frame 1. This eliminates concerns about lodging during harvesting and can meet different road conditions.
