Detailed implementation manners

[0041] The following will describe the detailed implementation manners of the present application with reference to the accompanying drawings. It should be understood that the detailed implementation manners described herein are only for explaining and illustrating the present application, and are not used to limit the present application.

[0042] An embodiment of the present application provides a husking system for a hybrid corn harvester, as Figure 1 - Figure 2 shown, the husking system 6 includes:

[0043] A husking driving part 601, which is used for electrically connecting with the generator 402 of the hybrid corn harvester;

[0044] A main husking transmission shaft 602, the input end of the main husking transmission shaft 602 is in transmission connection with the husking driving part 601 through a first transmission assembly 605;

[0045] A husking auger 603, the input end of the husking auger 603 is in transmission connection with the first output end of the main husking transmission shaft 602 through a second transmission assembly 606;

[0046] The peeling roller 604 is drivingly connected to the second output end of the peeling main transmission shaft 602 through the first transmission gear assembly 607.

[0047] Specifically, the hybrid corn harvester in this embodiment may be a four-row plate-type corn harvester and further includes an engine 401 and a generator 402. The input end of the generator 402 is connected to the power output end of the engine 401. The engine 401 may be a diesel engine, and the generator 402 may be a range extender. The peeling driving member 601 may be an electric motor (such as a permanent magnet synchronous motor). The peeling system 6 belongs to the main operating system of the hybrid corn harvester. The electric energy generated by the generator 402 is transmitted to the peeling driving member 601 to make the peeling driving member 601 rotate and drive other components in the peeling system 6.

[0048] The peeling system 6 further includes a peeling frame. The peeling main transmission shaft 602 is pivotally arranged at the top of the peeling frame. The peeling auger 603 is arranged inside the peeling frame, and part of the peeling auger 603 is exposed outside the peeling frame. The peeling roller 604 is pivotally arranged at the top of the peeling frame and on one side of the peeling main transmission shaft 602. The peeling frame, the peeling main transmission shaft 602, the peeling auger 603, the peeling roller 604, etc. together form a peeling machine. The first transmission gear assembly 607 includes a first driving gear and a first driven gear. The first driving gear is arranged on the peeling main transmission shaft 602 and is axially spaced from the first driven sprocket on the peeling main transmission shaft 602. The first driven gear is arranged on the peeling roller 604. The peeling driving member 601 is arranged on one side in the width direction of the peeling frame and above the peeling frame. When the peeling driving member 601 rotates, the power is transmitted to the peeling main transmission shaft 602 through the first transmission assembly 605. After the peeling main transmission shaft 602 rotates, the power is respectively transmitted to the peeling auger 603 and the peeling roller 604 through the second transmission assembly 606 and the first transmission gear assembly 607, so as to realize the power transmission between the peeling main transmission shaft 602 and the peeling roller 604, and further enable the peeling roller 604 to perform peeling operations.

[0049] In the peeling system 6 of this embodiment, the power transmission between the generator 402 and the peeling driving member 601 is the first-stage power transmission, the power transmission between the peeling driving member 601 and the peeling main transmission shaft 602 is the second-stage power transmission, and the power transmission between the peeling main transmission shaft 602 and the peeling auger 603 and the peeling roller 604 is the third-stage power transmission. As can be seen from the above, in this embodiment, there are three-stage power transmissions between the peeling driving member 601 and the peeling auger 603 and the peeling roller 604. The transmission structure is simple, the number of transmission components is small, the transmission efficiency and reliability are improved, and the failure rate is reduced.

[0050] In this embodiment, the operator can adjust the rotation speed of the peeling drive member 601 according to the signal feedback of the load change of the cutter bar drive member 501 to achieve the best matching of the action speeds of the components in the peeling system 6, avoid the occurrence of crop jams inside the peeling system 6, that is, effectively prevent jams in the peeling system 6, which is beneficial to improving the applicability of the peeling system 6 and the hybrid corn harvester.

[0051] In an embodiment of the present application, the first transmission assembly 605 includes a first driving sprocket, a first driven sprocket and a first transmission chain. The first driving sprocket is arranged on the output shaft of the peeling drive member 601, the first driven sprocket is arranged at the input end of the main peeling transmission shaft 602, and the first transmission chain is sleeved on the first driving sprocket and the first driven sprocket.

[0052] Specifically, the first driving sprocket and the first driven sprocket are spaced apart vertically. When the peeling drive member 601 rotates, it first transmits power to the first driving sprocket, the first driving sprocket then transmits power to the first transmission chain, after the first transmission chain rotates, it transmits power to the first driven sprocket, and the first driven sprocket then drives the main peeling transmission shaft 602 to pivot, thereby realizing the power transmission between the peeling drive member 601 and the main peeling transmission shaft 602. Further, the first driving sprocket can be selected as a double-row small sprocket (such as a 19-tooth double-row small sprocket), and the first driven sprocket can be selected as a double-row large sprocket (such as a 46-tooth double-row large sprocket). Driving the large sprocket with the small sprocket can reduce the rotation speed, so that the main peeling transmission shaft 602 rotates at a low speed.

[0053] In an embodiment of the present application, the second transmission assembly 606 includes a second driving sprocket, a second driven sprocket and a second transmission chain. The second driving sprocket is arranged on the main peeling transmission shaft 602, the second driven sprocket is arranged on the peeling auger 603, and the second transmission chain is sleeved on the second driving sprocket and the second driven sprocket.

[0054] Specifically, the second driving sprocket and the first driven sprocket are coaxially arranged and are both located on one side of the peeling frame in the width direction, and the second driven sprocket is arranged on the portion of the peeling auger 603 exposed from the peeling frame. Further, there are multiple peeling auger 603, and the multiple peeling auger 603 includes an upper peeling auger and a lower peeling auger spaced and distributed inside the peeling frame, and the number of the second driven sprocket is multiple and consistent with the number of the peeling auger 603, and the multiple second driven sprockets include a second upper auger driven sprocket and a second lower auger driven sprocket respectively arranged on the upper peeling auger and the lower peeling auger, and the first driven sprocket, the second upper auger driven sprocket and the second lower auger driven sprocket are all located on one side of the peeling frame in the width direction, and the first transmission chain is sleeved on the first driving sprocket, the second upper auger driven sprocket and the second lower auger driven sprocket. When the peeling main transmission shaft 602 rotates, it first transmits power to the second driving sprocket, and the second driving sprocket then transmits power to the second transmission chain. After the second transmission chain rotates, it transmits power to the second upper auger driven sprocket and the second lower auger driven sprocket at the same time. The second upper auger driven sprocket drives the upper peeling auger to pivot, and the second lower auger driven sprocket drives the lower peeling auger to pivot, thereby realizing the power transmission between the peeling main transmission shaft 602 and the upper peeling auger and the lower peeling auger. Furthermore, the number of gear teeth on the second driving sprocket is smaller than the number of gear teeth on the first driven sprocket, so that after the first driven sprocket transmits power to the peeling main transmission shaft 602 and rotates the peeling main transmission shaft 602, the second transmission assembly 606 can increase the rotation speed relative to the peeling main transmission shaft 602, thereby meeting the rotation speed requirements of the peeling auger 603 and the components connected to the peeling auger 603.

[0055] Furthermore, the second transmission assembly 606 also includes a tensioning wheel disposed on the peeling machine frame and used to keep the second conveying chain in a tensioned state.

[0056] In one embodiment of the present application, the peeling system 6 further includes a press 609 , and the output end of the peeling auger 603 is transmission-connected to the input end of the press 609 via a second transmission gear assembly.

[0057] Specifically, the presser 609 is used to perform a pressing operation on the crops to improve the peeling effect of the crops. The second transmission gear assembly includes a second driving gear and a second driven gear. The peeling system 6 further includes a first presser transmission chain assembly and a second presser transmission chain assembly. Among them, the first presser transmission chain assembly includes a first presser driving sprocket, a first presser driven sprocket, and a first presser transmission chain. A first bearing seat and a second bearing seat are also provided on the peeling frame. A first bearing seat rotating shaft and a second bearing seat rotating shaft are respectively provided on the first bearing seat and the second bearing seat. The first presser driving sprocket is arranged at the output end of the upper peeling auger. The first presser driven sprocket is arranged on the first bearing seat rotating shaft. The first presser transmission chain is sleeved on the first presser driving sprocket and the first presser driven sprocket. The second driving gear is also arranged on the first bearing seat rotating shaft and is coaxially distributed with the first presser driven sprocket. The second driven gear is arranged on the second bearing seat rotating shaft and meshes with the second driving gear. The second presser transmission chain assembly includes a second presser driving sprocket, a second presser driven sprocket, and a second presser transmission chain. The second presser driving sprocket is arranged on the second bearing seat rotating shaft and is coaxially distributed with the second driven gear. The second presser driven sprocket is arranged at the input end of the presser 609. The second presser transmission chain is sleeved on the second presser driving sprocket and the second presser driven sprocket, so as to realize the power transmission between the peeling auger 603 and the presser 609, and further enable the presser 609 to perform the pressing operation.

[0058] In an embodiment of the present application, the peeling system 6 further includes a throwing roller 608. The output end of the presser 609 is in transmission connection with the throwing roller 608 through a third transmission assembly.

[0059] Specifically, the throwing roller 608 is used to perform a throwing operation on the crops to throw the crops into the next working component (such as the grain box 14). The third transmission assembly includes a third driving sprocket, a third driven sprocket, a transition sprocket, and a third transmission chain. The third driving sprocket is arranged at the output end of the presser 609. The third driven sprocket is arranged on the throwing roller 608. The third transmission chain is sleeved on the third driving sprocket, the transition sprocket, and the third driven sprocket. The power is transmitted to the third driven sprocket by using the outer side of the third transmission chain, and the rotation direction of the throwing roller 608 is changed through the above settings, so that the throwing roller 608 can throw the crops into the grain box 14.

[0060] The second aspect of the present application provides a hybrid corn harvester, as Figure 14 shown. The hybrid corn harvester includes a hydraulic oil source, a traveling system 1 (as Figure 6 shown), a grain recovery device 3 (as Figure 8 shown), a power system 4 (as Figure 4 - Figure 5 shown), and a returning field system 2 (as Figure 7as shown), header system 5 (such as Figure 9 - Figure 10 as shown), elevator system 7 (such as Figure 11 as shown), and the above-mentioned husking system 6 for the hybrid corn harvester. The power system 4 includes:

[0061] An engine 401, including a first power output end and a second power output end;

[0062] A generator 402, the input end of the generator 402 is drivingly connected to the first power output end, and the power output end of the generator 402 is electrically connected to the traveling drive member 101 of the traveling system 1, the husking drive member 601 of the husking system 6, the header drive member 501 of the header system 5, the returning drive member 201 of the returning system 2, and the elevating drive member 701 of the elevator system 7;

[0063] A hydraulic pump 403, drivingly connected to the second power output end and used to pump hydraulic oil in the hydraulic oil source to the grain recovery drive member 301 of the grain recovery device 3.

[0064] Specifically, the hybrid corn harvester in this embodiment can be selected as a four-row plate-type corn harvester. The hydraulic oil source can be selected as a fuel tank storing hydraulic oil. The traveling system 1 (such as Figure 6 as shown) is used to enable the hybrid corn harvester to achieve the traveling function. The returning system 2 is used to convert agricultural waste into fertilizer and return it to the farmland. The header system 5 is used to pick corn ears and transport them to the elevator system (i.e., the elevator inlet). The traveling system 1, the power system 4, the returning system 2, the husking system 6, and the elevator system 7 all belong to the main operating systems of the hybrid corn harvester. The grain recovery device 3 is used to collect the corn grains that fall from the corn ears when the husking system 6 of the hybrid corn harvester husks the corn ears. The engine 401 in this embodiment can be selected as a diesel engine, and the traveling drive member 101 can be selected as an electric motor. After the engine 401 does work, it can output mechanical power outward through the first power output end and the second power output end. The output power of the first power output end is greater than the output power of the second power output end. The mechanical power output from the first power output end drives the generator 402 to implement the power generation function and generate electric energy. The above electric energy can be transmitted to the traveling drive member 101 and the husking drive member 601, so that the traveling drive member 101 and the husking drive member 601 can respectively implement the traveling drive function and the husking drive function, and further enable the traveling system 1 and the husking system 6 to respectively perform the traveling operation and the husking operation. In this embodiment, the traveling system 1 adopts an electric drive method, which can improve the traveling efficiency of the traveling system 1, greatly reduce the traveling fuel consumption. In addition, it can also utilize the peak power and peak torque characteristics of the traveling drive member 101 (i.e., the electric motor) to improve the off-road ability and the ability to cross ditches and bumps of the whole hybrid corn harvester.

[0065] In the header system 5, the header drive member 501 can be selected as a motor, and the electric energy generated by the generator 402 is supplied to the header drive member 501 to rotate the header drive member 501 and drive other components in the header system 5. Compared with the structure of the header system 5 in the prior art, this driving method can adjust the rotation speed of the header drive member 501 in real time, and then adjust the rotation speed of the header drive member 501 according to the planting situation and yield of crops in different regions, so as to realize the intelligent matching of the rotation speed and feeding amount of the header system 5 and improve the adaptability of the whole machine.

[0066] In the elevating system 7, the elevating drive member 701 can be selected as a motor, and the electric energy generated by the generator 402 can also be supplied to the elevating drive member 701 to rotate the elevating drive member 701 and drive other components in the elevating system 7. The operator can also adjust the elevating drive member 701 according to the signal feedback of the front-end feeding amount of the elevating system 7 to achieve the best matching of the rotation speed of the elevating system 7, which is beneficial to improving the applicability of the elevating system 7.

[0067] The grain recovery drive member 301 in this embodiment can be selected as a hydraulic motor. The grain recovery device 3 includes a recovery housing and a recovery auger. A grain recovery chamber is formed inside the recovery housing. A grain inlet and a grain outlet communicating with the grain recovery chamber are formed on the recovery housing. The recovery auger is arranged in the grain recovery chamber. The grain recovery drive member 301 is drivingly connected to the recovery auger. During the harvesting operation (or cutting operation) of the hybrid corn harvester, the grains scattered from the peeling system 6 can enter the grain recovery chamber through the grain inlet. After the hybrid corn harvester stops the harvesting operation, the grain recovery drive member 301 can drive the recovery auger to act to output the grains in the grain recovery chamber from the grain outlet. In this embodiment, compared with the main operating systems of the hybrid corn harvester, the power requirement of the grain recovery device 3 is lower.

[0068] In this embodiment, the traveling system 1, the tillage system 2, the header system 5, the peeling system 6 and the elevating system 7 of the hybrid corn harvester, as the main operating systems, are all driven by an electric drive method. This driving method has high efficiency, low energy consumption, convenient rotation speed adjustment and strong adaptability; the grain recovery device 3 is driven by a hydraulic drive method, and the energy consumption loss brought by this driving method is smaller. That is, in this embodiment, the hybrid corn harvester combines electric drive and hydraulic drive more reasonably, so that the power generated by the engine 401 is more reasonably distributed, which can effectively improve the overall driving efficiency of the hybrid corn harvester, is beneficial to reducing the overall energy consumption loss of the hybrid corn harvester. The above settings also optimize the overall transmission structure of the hybrid corn harvester, reduce the failure rate of the hybrid corn harvester, and improve the use reliability of the hybrid corn harvester.

[0069] Further, in this embodiment, the operating speed of the engine 401 is limited between 1200 rpm and 1900 rpm, so that the engine 401 can always operate in the high-efficiency energy-saving zone, reducing the fuel consumption of the engine and achieving the effect of energy conservation.

[0070] Further, in this embodiment, the speed and torque of the driving part in the form of a motor are not related to the speed of the engine, so the speed can be adjusted in real time, improving the flexibility of the operating speed of the operating parts of the whole machine and the adaptability to different working conditions.

[0071] In an embodiment of the present application, the power system 4 further includes a coupling 404 with two ends respectively connected to the first power output end and the input end of the generator 402.

[0072] Specifically, the coupling 404 is connected to the flywheel of the engine 401 and can be selected as a high-elastic flange coupling 404. The setting of the coupling 404 compensates for the coaxiality deviation between the flywheel of the engine 401 and the input end of the generator 402, improving the connection reliability between the engine 401 and the generator 402 and protecting the engine 401.

[0073] In an embodiment of the present application, the power system 4 further includes a power distribution device 17 (in this embodiment, the power distribution device 17 can be selected as the controller of the range extender and the double-electric-control multi-in-one controller assembly) communicatively connected to the generator 402, the traveling driving part 101, and the peeling driving part 601. The power distribution device 17 is used to distribute the electric energy generated by the generator 402 to the traveling driving part 101 and the peeling driving part 601 as needed.

[0074] In an embodiment of the present application, the traveling system 1 further includes a traveling gearbox 102, a wheel side reducer 103, and traveling wheels 104. The input shaft of the traveling gearbox 102 is drivingly connected to the traveling driving part 101, the output shaft of the traveling gearbox 102 is connected to the input shaft of the wheel side reducer 103 through a first transmission key, and the traveling wheels 104 are arranged on the output shaft of the wheel side reducer 103.

[0075] Specifically, the input shaft of the travel gearbox 102 is connected to the travel drive member 101 (such as a permanent magnet synchronous motor) through a first transmission key (such as a spline), so that the direct connection between the travel gearbox 102 and the travel drive member 101 can be realized, and when the travel drive member 101 rotates, the input shaft of the travel drive member 101 is directly driven to rotate; in this embodiment, an external spline body is formed on the output shaft of the travel gearbox 102, and a spline sleeve 16 matched with the above-mentioned external spline body is provided on the input shaft of the wheel-side reducer 103, thereby realizing the power transmission between the travel gearbox 102 and the wheel-side reducer 103, and when the output shaft of the wheel-side reducer 103 rotates, the travel wheel 104 rotates accordingly. Further, in the travel system 1 of this embodiment, the power transmission between the generator 402 and the travel drive member 101 is the first-level power transmission, and the power transmission between the travel gearbox 102 and the wheel-side reducer 103 is the second-level power transmission. It can be seen from the above that in this embodiment, the travel drive member 101 and the travel wheel 104 undergo two-level power transmission.

[0076] In one embodiment of the present application, the field returning system 2 also includes a field returning gearbox 202 and a first field returning machine 203, the input shaft of the field returning gearbox 202 is drivingly connected to the field returning drive member 201, and the output shaft of the field returning gearbox 202 is drivingly connected to the field returning machine 203 through the first conveyor belt assembly 204.

[0077] Specifically, the returning system 2 is used to convert agricultural waste into fertilizer and return it to the farmland, and it also belongs to the main operating system of the hybrid corn harvester. The returning driving member 201 can be selected as a motor, and the electric energy generated by the generator 402 can also be distributed by the distribution device 17 to the returning driving member 201, so that the returning driving member 201 rotates and drives other components in the returning system 2. The input shaft of the returning transmission 202 is connected to the returning driving member 201 (such as a high-speed permanent magnet motor) through a second transmission key (such as a spline), so as to realize the direct connection between the returning transmission 202 and the returning driving member 201. When the returning driving member 201 rotates, it directly drives the input shaft of the returning driving member 201 to rotate; the returning system 2 further includes a returning frame 206, and the front shredder 506 is arranged below the returning frame 206 and can perform a second returning shredding operation, such as shredding the lower part of the corn stalks in the farmland; the first conveyor belt assembly 204 includes a first driving pulley, a first driven pulley and a first conveyor belt. The first driving pulley is connected to the output shaft of the returning transmission 202, the first driven pulley is arranged on the rotating shaft of the front shredder 506 and is arranged at an interval from the first driving pulley, and the first conveyor belt is sleeved on the first driving pulley and the first driven pulley, so as to realize the power transmission between the returning transmission 202 and the front shredder 506. That is, when the returning driving member 201 rotates, it sequentially transmits the power to the returning transmission 202, the first conveyor belt assembly 204 and the front shredder 506, and the front shredder 506 performs the second returning shredding operation driven by the first conveyor belt assembly 204. In this embodiment, when the front shredder 506 performs the second returning shredding operation, the rotation speeds of the first driving pulley and the first driven pulley are the rated working speeds (such as 2433 r / min) to ensure that the front shredder 506 has sufficient power; further, the operator can also adjust the rotation speed of the returning driving member 201 according to the actual shredding effect of the front shredder 506, and then realize the adjustment of the rotation speed of the front shredder 506 to achieve a better returning effect, which is beneficial to improving the adaptability of the whole agricultural harvesting equipment.

[0078] Further, in the returning system 2 of this embodiment, the power transmission between the generator 402 and the returning motor is the first-stage power transmission, and the power transmission between the returning transmission 202 and the front shredder 506 is the second-stage power transmission. As can be seen from the above, there are two-stage power transmissions between the returning driving member 201 and the front shredder 506 in this embodiment.

[0079] In one embodiment of the present application, the returning system 2 further includes a returning transmission shaft 205 and a returning bearing. The input end of the returning transmission shaft 205 is connected to the output shaft of the returning gearbox 202 through a fourth transmission key. The output end of the returning transmission shaft 205 is drivingly connected to the front shredder 506 through a first conveyor belt assembly 204. The returning bearing is sleeved on the returning transmission shaft 205 and is used to bear the radial tension from the first conveyor belt assembly 204.

[0080] Specifically, the fourth transmission key in this embodiment can be selected as a spline. For example, a spline connection is provided between the input end of the returning transmission shaft 205 and the output shaft of the returning gearbox 202, which can achieve a direct connection between the returning gearbox 202 and the returning transmission shaft 205. When the returning gearbox 202 rotates, it directly drives the returning transmission shaft 205 to rotate. The first driving pulley is arranged at the output end of the returning transmission shaft 205. After the returning transmission shaft 205 rotates, the power is transmitted to the first conveyor belt assembly. Since the radial tension of the first conveyor belt in the returning system 2 is relatively large, the inner ring of the returning bearing is sleeved on the outer peripheral side of the returning transmission shaft 205, the outer ring of the returning bearing is arranged on the bearing seat, and the bearing seat is arranged on the returning frame 206. The radial tension from the first conveyor belt is sequentially transmitted to the returning transmission shaft 205, the returning bearing, the bearing seat, and the returning frame 206, thereby playing a protective role for the returning gearbox 202.

[0081] In one embodiment of the present application, the header system 5 further includes a header gearbox 502, a header auger 503, and a corn picker assembly 504. The input shaft of the header gearbox 502 is drivingly connected to the header drive member 501. The first output shaft of the header gearbox 502 is simultaneously drivingly connected to the header auger 503 and the corn picker assembly 504 through a first drive chain assembly 505.

[0082] Specifically, there are two header driving members 501 in this embodiment. The header system 5 further includes a first header unit, a second header unit, and a header frame welding 508. Both the first header unit and the second header unit include a header driving member 501, a header gearbox 502, and two ear picking assemblies 504. The first header unit and the second header unit are respectively arranged on both sides in the width direction of the header frame welding 508. There is one header auger 503, which is arranged along the width direction of the header frame welding 508. The number of ear picking assemblies 504 is four. Two ear picking assemblies 504 form a group, and the two groups of ear picking assemblies 504 are respectively arranged on both sides in the width direction of the header frame welding 508. The header gearbox 502 is arranged on the header frame and has a first output shaft and a second output shaft. Among them, the rotational speed of the first output shaft is less than that of the second output shaft. The input shaft of the header gearbox 502 is connected to the header driving member 501 (such as a permanent magnet synchronous motor) through a third transmission key (such as a spline), so as to achieve a direct connection between the header gearbox 502 and the header driving member 501. When the header driving member 501 rotates, it directly drives the input shaft of the header gearbox 502 to rotate. The first transmission chain assembly 505 includes a fourth driving sprocket, a fourth driven sprocket, a fifth driven sprocket, and a fourth transmission chain. The fourth driving sprocket is arranged on the first output shaft of the header gearbox 502. The fourth driven sprocket is arranged on the header auger 503. The fifth driven sprocket is arranged on the ear picking assembly 504 (the two ear picking assemblies 504 in the same group are connected together by an ear picking assembly coupling and are jointly driven by the fifth driven sprocket). The fourth transmission chain is sleeved on the fourth driving sprocket, the fourth driven sprocket, and the fifth driven sprocket. When the header driving member 501 rotates, it sequentially transmits power to the header gearbox 502 and the first transmission chain assembly 505, and then the first transmission chain assembly 505 transmits power to the header auger 503 and the ear picking assembly 504 at the same time, so that the header auger 503 and the ear picking assembly 504 act simultaneously. The above settings are beneficial to improving the working efficiency of the header system 5, and also simplify the transmission structure, which is beneficial to reducing the failure rate of the header system 5 and the hybrid corn harvester.

[0083] In an embodiment of the present application, the ear picking assembly 504 includes an ear picking gearbox 509, a stalk pulling roller 510, and a finger chain 511. The input shaft of the ear picking gearbox 509 is in transmission connection with the first output shaft of the header gearbox 502 through the first transmission chain assembly 505. The first output end of the ear picking gearbox 509 is connected to the stalk pulling roller 510, and the second output end of the ear picking gearbox 509 is connected to the finger chain 511.

[0084] Specifically, the second driven sprocket is arranged on the input shaft of the ear picking gearbox 509. The first output shaft (i.e., the first output end) of the ear picking gearbox 509 is connected to the pulling roller 510. The ear picking assembly 504 further includes an ear picking platform frame, a driving reel, and a driven reel. The ear picking platform frame is arranged above the ear picking gearbox 509. The driving reel is arranged on the second output shaft (i.e., the second output end) of the ear picking gearbox 509. The driven reel is arranged on the ear picking platform frame. The reel chain 511 is sleeved on the driving reel and the driven reel. Driven by the second driven sprocket, the first output shaft and the second output shaft of the ear picking gearbox 509 rotate simultaneously, thereby driving the pulling roller 510 and the reel chain 511 to act simultaneously, so that the pulling roller 510 performs the pulling and ear picking operation and the reel chain 511 performs the reel operation.

[0085] In an embodiment of the present application, the header system 5 further includes a front shredder 506. The second output shaft of the header gearbox 502 is in transmission connection with the front shredder 506 through a second conveyor belt assembly 507.

[0086] Specifically, the front shredder 506 is used to perform a second field chopping operation on the crop stalks (in this embodiment, the second field chopping operation is performed before the first field chopping operation), such as chopping the upper part of the corn stalks in the farmland. In this embodiment, the first header unit and the second header unit are respectively connected to the sprockets on the left and right sides of the front shredder 506 to drive both sides of the front shredder 506 simultaneously. The second conveyor belt assembly 507 includes a second driving pulley, a second driven pulley, and a second conveyor belt. The second driving pulley is arranged on the second output shaft of the header gearbox 502. The second driven pulley is arranged on the rotating shaft of the front shredder 506 and is arranged at an interval from the second driving pulley. The second conveyor belt is sleeved on the second driving pulley and the second driven pulley, thereby realizing the power transmission between the header gearbox 502 and the front shredder 506. That is, when the header driving member 501 rotates, it sequentially transmits the power to the header gearbox 502, the second conveyor belt assembly 507, and the front shredder 506. Driven by the second conveyor belt assembly 507, the front shredder 506 performs the field chopping operation. Compared with the transmission connection between the second output shaft of the header gearbox 502 and the front shredder 506 through a conveyor chain assembly, the setting in this embodiment can avoid problems such as high chain linear speed, fast wear, and large noise. Using the second conveyor belt assembly 507 to drive the front shredder 506 to work can reduce the failure rate, reduce vibration and noise, and at the same time can play a role in overload slipping and protecting the front shredder 506.

[0087] In one embodiment of the present application, the elevating system 7 further includes an elevator 702, a lower blower 703, an upper blower 704, and a stem discharging roller 705. The input end of the first transmission shaft of the lower blower 703 is drivingly connected to the elevating driving member 701. The output end of the first transmission shaft is drivingly connected to the input end of the second transmission shaft of the upper blower 704 through a third conveyor belt assembly 706. The input end of the stem discharging roller 705 is drivingly connected to the output end of the second transmission shaft through a fourth conveyor belt assembly 707. The output end of the stem discharging roller 705 is drivingly connected to the elevator 702 through a fifth transmission chain assembly.

[0088] Specifically, an elevating cavity is formed inside the elevator 702. An elevating channel for transporting crops (such as corn) is formed in the elevating cavity. A lower blower mounting bracket is provided on one side of the elevator 702. The lower blower 703 is disposed on the lower blower mounting bracket. The air outlet of the lower blower 703 is communicated with the elevating cavity for blowing air into the elevating cavity. The upper blower 704 is disposed above the lower blower 703 and the lower blower 703 and the upper blower 704 are respectively on opposite sides of the elevator 702. The air suction port of the upper blower 704 is communicated with the elevating cavity for extracting the gas in the elevating cavity outwards. The stem discharging roller 705 is disposed on the elevator 702 and above the upper blower 704.

[0089] The elevating drive member 701 is connected to the first transmission shaft of the lower blower 703 through a fourth transmission key (such as a spline), so as to achieve a direct connection between the first transmission shaft and the elevating drive member 701. When the elevating drive member 701 rotates, it directly drives the first transmission shaft to rotate, thereby enabling the lower blower 703 to perform the air supply operation; The third conveyor belt assembly 706 includes a third driving pulley, a third driven pulley and a third conveyor belt. The third driving pulley is arranged on the first transmission shaft and located at the output end of the first transmission shaft. The third driven pulley is arranged on the second transmission shaft of the upper blower 704 and located at the input end of the second transmission shaft. The third conveyor belt is sleeved on the third driving pulley and the third driven pulley, so as to achieve power transmission between the lower blower 703 and the upper blower 704; The fourth conveyor belt assembly 707 includes a fourth driving pulley, a fourth driven pulley and a fourth conveyor belt. The fourth driving pulley is arranged on the second transmission shaft and located at the output end of the second transmission shaft. The fourth driven pulley is arranged on the stem discharging roller 705 and located at the input end of the stem discharging roller 705. The fourth conveyor belt is sleeved on the fourth driving pulley and the fourth driven pulley, so as to achieve power transmission between the upper blower 704 and the stem discharging roller 705; The second transmission chain assembly includes a fifth driving sprocket, a sixth driven sprocket and a fifth transmission chain. The fifth driving sprocket is arranged on the stem discharging roller 705 and located at the output end of the stem discharging roller 705. The sixth driven sprocket is arranged on the power input end of the elevator 702. The fifth transmission chain is sleeved on the fifth driving sprocket and the sixth driven sprocket, so as to achieve power transmission between the stem discharging roller 705 and the elevator 702. That is, when the elevating drive member 701 rotates, it sequentially transmits power to the lower blower 703, the third conveyor belt assembly 706, the upper blower 704, the fourth conveyor belt assembly 707, the stem discharging roller 705, the second transmission chain assembly and the elevator 702, thereby enabling the lower blower 703, the upper blower 704, the stem discharging roller 705 and the elevator 702 to perform their respective functions. The use of the third conveyor belt assembly 706 and the fourth conveyor belt assembly 707 is beneficial to reducing the noise generated by the elevating system 7, and can also ensure that the lower blower 703 and the upper blower 704 have a sufficiently high rotational speed, which is beneficial to improving the removal efficiency of the residual parts (such as corn whiskers) of the crops in the elevating cavity. Further, the fifth driving sprocket is a small sprocket, and the sixth driven sprocket is a large sprocket, that is, the number of teeth of the fifth driving sprocket is less than that of the sixth driven sprocket. In this embodiment, the rotational speed of the elevator 702 is relatively low. After the stem discharging roller 705 rotates, its rotational speed is reduced through the third transmission assembly and then drives the elevator 702 to rotate, so that the rotational speed of the elevator 702 is adapted to the movement speed of other components in the hybrid corn harvester, thereby ensuring the harvesting quality of the hybrid corn harvester.

[0090] In the elevating system 7 of this embodiment, the power transmission between the generator 402 and the elevating driving member 701 is the first-stage power transmission, the power transmission between the lower blower 703 and the upper blower 704 is the second-stage power transmission, the power transmission between the upper blower 704 and the stem discharging roller 705 is the third-stage power transmission, and the power transmission between the stem discharging roller 705 and the elevator 702 is the fourth-stage power transmission. As can be seen from the above, in this embodiment, there are four stages of power transmission between the elevating driving member 701 and the elevator 702. The above power transmission route is simple and greatly improves the transmission efficiency.

The second hydraulic driving member 9 is arranged on one side of the bract shredder 8, and the second hydraulic driving member 9 and the main shaft of the bract shredder 8 are connected together through a fifth transmission key (such as a spline), so as to realize the direct connection between the second hydraulic driving member 9 and the bract shredder 8. After the second hydraulic driving member 9 acts, it drives the main shaft of the bract shredder 8 to rotate, and then the bract shredder 8 performs the bract shredding operation. As can be seen from the above, there is only one stage of power transmission between the bract shredder 8 and the hydraulic pump 403 (or the engine 401). The transmission route is simple, and it also makes the maintenance of the bract shredder 8 more convenient and fast.

[0093] In one embodiment of the present application, as Figure 13 shown, the hybrid corn harvester further includes a grain cleaning blower 10 and a third hydraulic driving member 11 that is drivingly connected to the grain cleaning blower 10.

The third hydraulic driving member 11 is arranged on one side of the grain cleaning blower 10, and the third hydraulic driving member 11 and the main shaft of the grain cleaning blower 10 are connected together through a sixth transmission key (such as a spline), so as to realize the direct connection between the third hydraulic driving member 11 and the grain cleaning blower 10. After the third hydraulic driving member 11 acts, it drives the main shaft of the grain cleaning blower 10 to rotate, and then the grain cleaning blower 10 performs the grain cleaning operation. As can be seen from the above, there is only one stage of power transmission between the grain cleaning blower 10 and the hydraulic pump 403 (or the engine 401). The transmission route is simple and the transmission efficiency is improved.

[0095] In an embodiment of the present application, the hybrid corn harvester further includes a fourth hydraulic driving member 12 for driving the header system 5 to lift, and the hydraulic pump 403 is also used to pump hydraulic oil to the fourth hydraulic driving member 12.

[0096] Specifically, in this embodiment, the fourth hydraulic driving member 12 may be selected as a hydraulic cylinder. The fourth hydraulic driving member 12 is drivingly connected to the lifting driving end 512 of the header system. The fourth hydraulic driving member 12 expands and contracts under the pumping action of the hydraulic pump 403, so that the header system 5 can be lifted, so as to change the height of the header system 5 according to actual operation requirements, which is convenient for improving the operation convenience of the header system 5 and can also prevent the header system 5 from colliding with the ground (or crops on the ground, etc.) when in a non-working state. In addition, as can be seen from the above, only one-level power transmission occurs between the lifting driving end 512 of the header system and the hydraulic pump 403 (or the engine 401), which has the advantages of simple transmission route and low failure rate.

[0097] In an embodiment of the present application, the hybrid corn harvester further includes a fifth hydraulic driving member 13 for driving the traveling system 1 to steer, and the hydraulic pump 403 is also used to pump hydraulic oil to the fifth hydraulic driving member 13.

[0098] Specifically, in this embodiment, the fifth hydraulic driving member 13 may be selected as a hydraulic cylinder. The fifth hydraulic driving member 13 is drivingly connected to the rear axle 105 in the traveling system 1. The fifth hydraulic driving member 13 expands and contracts under the pumping action of the hydraulic pump 403, so that the rear axle 105 acts to realize the steering function of the traveling system 1, and thus the forward direction of the hybrid corn harvester can be changed according to actual needs. As can be seen from the above, only one-level power transmission occurs between the rear axle 105 of the traveling system 1 and the hydraulic pump 403 (or the engine 401), effectively improving the transmission efficiency between the rear axle 105 of the traveling system 1 and the hydraulic pump 403 (or the engine 401).

[0099] In an embodiment of the present application, the hybrid corn harvester further includes a grain tank 14 and a sixth hydraulic driving member 15 for driving the grain tank 14 to flip, and the hydraulic pump 403 is also used to pump hydraulic oil to the sixth hydraulic driving member 15.

A storage cavity is formed inside the grain box 14, and a crop inlet and outlet communicating with the storage cavity is formed at the top of the grain box 14; the sixth hydraulic driving member 15 can be selected as a hydraulic cylinder, and the sixth hydraulic driving member 15 is connected to the grain box 14. The sixth hydraulic driving member 15 expands and contracts under the pumping action of the hydraulic pump 403, so that the grain box 14 rotates relative to the frame to pour out the collected crops from the grain box 14. As can be seen from the above, only one-stage power transmission occurs between the grain box 14 and the hydraulic pump 403 (or the engine 401), and the transmission route is short and convenient for maintenance.

[0101] In this application, since the seed recovery device 3 is driven only when the hybrid corn harvester stops harvesting operations (that is, when the corn ear transfer operation of the elevating system 7, the lifting operation of the cutting table system 5, the tilting operation of the grain box 14, the bract chopping operation of the bract chopper 8, and the seed impurity removal operation of the seed impurity removal fan 10 all stop) to achieve seed recovery (that is, to output the seeds in the seed recovery cavity from the seed outlet), that is, when the seed recovery device 3 operates, the elevating system 7, the cutting table system 5, the grain box 14, the bract chopper 8, and the seed impurity removal fan 10 are all in a stopped state. Therefore, the seed recovery device 3 can use the idle time of the hydraulic pump 403 to pump hydraulic oil for it.
