Detailed implementation mode

[0042] The following will describe in detail the specific implementation mode of the present application with reference to the accompanying drawings. It should be understood that the specific implementation mode described herein is only for the purpose of illustration and explanation of the present application, and is not used to limit the present application.

[0043] To achieve the above object, in the first aspect of the present application, a header system for a hybrid corn harvester is provided, as Figures 1 - 2 shown, the header system 5 includes:

[0044] A header driving part 501, configured to be electrically connected to the generator 402 of the hybrid corn harvester;

[0045] A header gearbox 502, the input shaft of the header gearbox 502 is drivingly connected to the header driving part 501;

[0046] A header auger 503;

[0047] An ear picking assembly 504, arranged on one side of the header auger 503;

[0048] The first transmission component 505 is drivingly connected to the first output shaft of the header gearbox 502 and is configured to simultaneously transmit the power from the header gearbox 502 to the header auger 503 and the ear picker assembly 504.

[0049] 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 header drive member 501 may be an electric motor (such as a permanent magnet synchronous motor). The header system 5 belongs to the main operating system of the hybrid corn harvester. The electric energy generated by the generator 402 is transmitted to the header drive member 501 to cause the header drive member 501 to rotate and drive other components in the header system 5.

[0050] In this embodiment, there are two header drive members 501. 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 drive member 501, a header gearbox 502, and two ear picker 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. The number of header augers 503 is one and is arranged in the width direction of the header frame welding 508. The number of ear picker assemblies 504 is four. Two ear picker assemblies 504 form a group, and the two groups of ear picker 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. When the header drive member 501 rotates, it sequentially transmits the power to the header gearbox 502 and the first transmission component 505, and then the first transmission component 505 simultaneously transmits the power to the header auger 503 and the ear picker assembly 504, so that the header auger 503 and the ear picker assembly 504 act simultaneously. The above arrangement is beneficial to improving the working efficiency of the header system 5, simplifies the transmission structure, and is beneficial to reducing the failure rate of the header system 5 and the hybrid corn harvester.

[0051] Furthermore, in this embodiment, the header drive member 501 is in an electric drive mode. Compared with the structure of the header system 5 in the prior art, this drive mode 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 conditions and yields of crops in different regions to achieve intelligent matching of the rotation speed and feeding amount of the header system 5 and improve the adaptability of the whole machine.

[0052] In an embodiment of the present application, the first transmission assembly 505 includes a first driving sprocket, a first driven sprocket, a second driven sprocket, and a first transmission chain. The first driving sprocket is disposed on the first output shaft of the header gearbox 502, the first driven sprocket is disposed on the header auger 503, the second driven sprocket is disposed on the ear picking assembly 504, and the first transmission chain is sleeved on the first driving sprocket, the first driven sprocket, and the second driven sprocket. Further, the first driven sprocket is disposed at one axial end of the header auger 503. In this embodiment, two ear picking assemblies 504 in the same group are connected together by an ear picking assembly coupling and are jointly driven by the second driven sprocket. When the header driving member 501 rotates, it sequentially transmits power to the header gearbox 502, the first driving sprocket, and the first transmission chain. The first transmission chain then transmits power to the first driven sprocket and the second driven sprocket simultaneously. The first driven sprocket and the second driven sprocket then respectively transmit power to the header auger 503 and the ear picking assembly 504, so that the header auger 503 and the ear picking assembly 504 act simultaneously, simplifying the transmission structure of the header system 5 and reducing the failure rate.

[0053] In an embodiment of the present application, the ear picking assembly 504 includes an ear picking gearbox 509, a pulling roller 510, and a reel 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 assembly 505. The first output end of the ear picking gearbox 509 is connected to the pulling roller 510, and the second output end of the ear picking gearbox 509 is connected to the reel chain 511.

[0054] Specifically, the second driven sprocket is disposed 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) 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 disposed above the ear picking gearbox 509. The driving reel is disposed on the second output shaft (i.e., the second output end of the ear picking gearbox 509) of the ear picking gearbox 509. The driven reel is disposed on the ear picking platform frame. The reel chain 511 is sleeved outside 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 operation of pulling and ear picking and the reel chain 511 performs the operation of reeling.

[0055] In an embodiment of the present application, the input shaft of the header gearbox 502 and the header driving member 501 are connected together by a first transmission key.

[0056] Specifically, the first transmission key in this embodiment can be selected as a spline, that is, the input shaft of the cutter bar gearbox 502 is connected to the cutter bar drive member 501 through a spline, thereby realizing a direct connection between the cutter bar gearbox 502 and the cutter bar drive member 501. When the cutter bar drive member 501 rotates, it can directly drive the rotation of the input shaft of the cutter bar gearbox 502, and energy loss between the cutter bar gearbox 502 and the cutter bar drive member 501 is minimized.

[0057] In an embodiment of the present application, the cutter bar system 5 further includes a front shredder 506. The second output shaft of the cutter bar gearbox 502 is drivingly connected to the front shredder 506 through a second transmission assembly 507, wherein the rotational speed of the second output shaft is greater than that of the first output shaft.

[0058] Specifically, in this embodiment, the first cutter bar unit and the second cutter bar 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 front shredder 506 is used to perform a first field chopping operation on the crop stalks (the first field chopping operation in this embodiment is performed before the second field chopping operation), such as chopping the upper part of the corn stalks in the farmland. The cutter bar system 5 in this embodiment realizes the power transmission between the cutter bar gearbox 502 and the front shredder 506 by setting the second transmission assembly 507. That is, when the cutter bar drive member 501 rotates, it sequentially transmits the power to the cutter bar gearbox 502, the second transmission assembly, and the front shredder 506. The front shredder 506 performs the first field chopping operation under the drive of the second transmission assembly.

[0059] In an embodiment of the present application, the second transmission assembly 507 includes a first driving pulley, a first driven pulley, and a first conveyor belt. The first driving pulley is arranged on the second output shaft of the cutter bar gearbox 502, 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.

[0060] Specifically, when the cutter bar drive member 501 rotates, it sequentially transmits the power to the cutter bar gearbox 502, the first driving pulley, the first conveyor belt, and the first driven pulley. The front shredder 506 performs the first field chopping operation under the drive of the first driven pulley. Compared with using a transmission chain assembly for driving connection, using a conveyor belt assembly to transmit power between the cutter bar gearbox 502 and the front shredder 506 in this embodiment can avoid problems such as high chain linear speed, fast wear, and large noise, 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.

[0061] The second aspect of the present application provides a hybrid corn harvester, such as Figure 14As shown, the hybrid corn harvester includes a hydraulic oil source, a traveling system 1 (as shown in Figure 6 ), a grain recycling device 3 (as shown in Figure 8 ), a power system 4 (as shown in Figures 4 - 5 ), a straw returning system 2 (as shown in Figure 7 ), a husking system 6 (as shown in Figures 9 - 10 ), a lifting system 7 (as shown in Figure 11 ), and the above-mentioned cutting table system 5 for the hybrid corn harvester. The power system 4 includes:

[0062] An engine 401, including a first power output end and a second power output end;

[0063] 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 cutting table drive member 501 of the cutting table system 5, the straw returning drive member 201 of the straw returning system 2, the husking drive member 601 of the husking system 6, and the lifting drive member 701 of the lifting system 7;

[0064] A hydraulic pump 403, drivingly connected to the second power output end and used to pump the hydraulic oil in the hydraulic oil source to the grain recycling drive member 301 of the grain recycling device 3.

[0065] 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, and the traveling system 1 (as shown in Figure 6The hybrid corn harvester is used to realize the walking function of the hybrid corn harvester. The field return system 2 is used to convert agricultural waste into fertilizer and return it to the farmland. The harvester system 5 is used to pick corn ears and transport them to the elevator system (i.e., the elevator entrance). The walking system 1, the power system 4, the field return system 2, the peeling system 6, and the elevator system 7 are all main operating systems of the hybrid corn harvester; the grain recovery device 3 is used to collect corn grains that fall from the corn ears when the peeling system 6 of the hybrid corn harvester peels the corn ears. The engine 401 in this embodiment can be selected as a diesel engine, and the travel drive 101 can be selected as a motor. After the engine 401 works, it can output mechanical power to the outside 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 electrical energy. The above electrical energy can be transmitted to the travel drive 101 and the header drive 501, so that the travel drive 101 and the header drive 501 can respectively implement the travel drive function and the header drive function, thereby enabling the travel system 1 and the header system 5 to respectively perform the travel operation and the harvesting operation (the harvesting operation in this embodiment includes the operation of pulling the stems and picking the ears and the operation of pulling the rice). In this embodiment, the travel system 1 adopts an electric drive mode, which can improve the travel efficiency of the travel system 1 and greatly reduce the travel fuel consumption. In addition, the peak power and peak torque characteristics of the travel drive 101 (i.e., the motor) can also be used to improve the ability of the hybrid corn harvester to get out of trouble and pass through ditches and ridges.

[0066] In the peeling system 6, the peeling drive 601 can be selected as a motor, and the electric energy generated by the generator 402 can also be allocated to the peeling drive 601 to make the peeling drive 601 rotate and drive other components in the peeling system 6. The operator can also adjust the rotation speed of the peeling drive 601 according to the signal feedback of the load change of the cutter drive 501 to achieve the best matching of the movement speed of each component in the peeling system 6, which can avoid the occurrence of crop blockage inside the peeling system 6, that is, it can achieve effective anti-blocking of the peeling system 6, which is beneficial to improve the applicability of the peeling system 6 and the hybrid corn harvester.

[0067] In the lifting system 7, the lifting drive component 701 can be selected as a motor, and the electric energy generated by the generator 402 can also be distributed to the lifting drive component 701 to make the lifting drive component 701 rotate and drive other components in the lifting system 7. The operator can also adjust the lifting drive component 701 according to the signal feedback of the front-end feed amount of the lifting system 7 to achieve the best match of the rotation speed of the lifting system 7, which is conducive to improving the applicability of the lifting system 7.

[0068] In this embodiment, the grain recovery driving member 301 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 driving member 301 is drivingly connected to the recovery auger. During the harvesting operation (or reaping 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 driving 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 operation systems of the hybrid corn harvester, the power requirement of the grain recovery device 3 is lower.

[0069] 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 are all driven in an electric drive mode as the main operation systems. This drive mode has high efficiency, low energy consumption, convenient speed adjustment and strong adaptability; the grain recovery device 3 is driven in a hydraulic drive mode. This drive mode brings less energy consumption loss. 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 drive 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.

[0070] Furthermore, in this embodiment, the working speed of the engine 401 is limited between 1200 rpm and 1900 rpm, so that the engine 401 can always work in the high-efficiency and energy-saving area, reduce the fuel consumed by the engine, and achieve the energy-saving effect.

[0071] Furthermore, in this embodiment, the speed and torque of the driving member in the form of a motor are not related to the speed of the engine, so the speed can be adjusted in real time, which improves the flexibility of the operation speed of the operation components of the whole machine and the adaptability to different working conditions.

[0072] In an embodiment of the present application, the power system 4 further includes a coupling 404 with both ends respectively connected to the first power output end and the input end of the generator 402. 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, improves the connection reliability between the engine 401 and the generator 402, and also plays a protective role for the engine 401.

[0073] In one embodiment of the present application, the power system 4 also includes a power distribution device 17 which is communicatively connected to the generator 402, the travel drive 101, and the cutter drive 501 (in this embodiment, the power distribution device 17 can be selected as a controller of the range extender and a dual-electric all-in-one controller assembly), and the power distribution device 17 is used to distribute the electric energy generated by the generator 402 to the travel drive 101 and the cutter drive 501 as needed.

[0074] In the embodiments of the present application, Figure 6 As shown, the travel system 1 also includes a travel gearbox 102, a wheel-side reducer 103 and a travel wheel 104. The input shaft of the travel gearbox 102 is drivingly connected to the travel drive member 101, and the output shaft of the travel gearbox 102 is connected to the input shaft of the wheel-side reducer 103 through a second transmission key. The travel wheel 104 is 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 second 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 matching the 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, Figure 7 As shown, the field returning system 2 also includes a field returning gearbox 202 and a field returning machine 203. The input shaft of the field returning gearbox 202 is drivingly connected to the field returning driving 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-to-field drive 201 can be selected as a motor, and the electric energy generated by the generator 402 can also be distributed to the returning-to-field drive 201 under the distribution action of the power distribution device 17, so that the returning-to-field drive 201 rotates and drives other components in the returning-to-field system 2. The input shaft of the returning-to-field gearbox 202 and the returning-to-field drive 201 (such as a high-speed permanent magnet motor) are connected together through a third transmission key (such as a spline), so that a direct connection between the returning-to-field gearbox 202 and the returning-to-field drive 201 can be realized. When the returning-to-field drive 201 rotates, it directly drives the input shaft of the returning-to-field drive 201 to rotate; the returning-to-field system 2 also includes a returning-to-field frame 206, and the returning-to-field machine 203 is arranged below the returning-to-field frame 206 and can perform a second returning-to-field shredding operation, such as shredding the lower part of the corn stalks in the farmland; the first conveyor belt assembly 204 includes a second driving pulley, a second driven pulley, and a second driven pulley. The second driving pulley is connected to the output shaft of the field return gearbox 202, the second driven pulley is arranged on the rotating shaft of the field return machine 203 and is arranged at an interval with the second driving pulley, and the second conveyor belt is sleeved on the second driving pulley and the second driven pulley, so as to realize the power transmission between the field return gearbox 202 and the field return machine 203, that is, when the field return driving member 201 rotates, it transmits the power to the field return gearbox 202, the first conveyor belt assembly 204 and the field return machine 203 in turn, and the field return machine 203 performs the second field return shredding operation driven by the first conveyor belt assembly 204. In this embodiment, when the field return machine 203 performs the second field return and shredding operation, the rotation speed of the second driving pulley and the second driven pulley is the rated working speed (such as 2433r / min) to ensure that the field return machine 203 has sufficient power; further, the operator can also adjust the rotation speed of the field return drive 201 according to the actual shredding effect of the field return machine 203, thereby realizing the adjustment of the rotation speed of the field return machine 203 to achieve a better field return effect, which is conducive to improving the adaptability of the entire agricultural harvesting equipment.

[0078] Furthermore, in the field returning system 2 of the present embodiment, the power transmission between the generator 402 and the field returning motor is the first-stage power transmission, and the power transmission between the field returning gearbox 202 and the field returning machine 203 is the second-stage power transmission. From the above, it can be seen that in the present embodiment, two-stage power transmission is experienced between the field returning drive 201 and the field returning machine 203.

[0079] In one embodiment of the present application, the field returning system 2 also includes a field returning transmission shaft 205 and a field returning bearing. The input end of the field returning transmission shaft 205 is connected to the output shaft of the field returning gearbox 202 through a fourth transmission key. The output end of the field returning transmission shaft 205 is connected to the field returning machine 203 through a first conveyor belt assembly 204. The field returning bearing is sleeved on the field returning transmission shaft 205 and is used to withstand 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, the input end of the straw returning transmission shaft 205 and the output shaft of the straw returning gearbox 202 are spline-connected, which can achieve a direct connection between the straw returning gearbox 202 and the straw returning transmission shaft 205. When the straw returning gearbox 202 rotates, it directly drives the straw returning transmission shaft 205 to rotate. The first driving pulley is arranged at the output end of the straw returning transmission shaft 205. After the straw returning transmission shaft 205 rotates, it transmits power to the first transmission belt assembly. Since the radial tension of the first conveyor belt in the straw returning system 2 is relatively large, the inner ring of the straw returning bearing is sleeved on the outer peripheral side of the straw returning transmission shaft 205, the outer ring of the straw returning bearing is arranged on the bearing seat, and the bearing seat is arranged on the straw returning frame 206. The radial tension from the first conveyor belt is sequentially transmitted to the straw returning transmission shaft 205, the straw returning bearing, the bearing seat, and the straw returning frame 206, thereby playing a protective role for the straw returning gearbox 202.

The first driving gear is arranged on the peeling main transmission shaft 602 and is axially spaced from the third driven sprocket on the peeling main transmission shaft 602. The first driven gear is arranged on the peeling roller 604 to achieve power transmission between the peeling main transmission shaft 602 and the peeling roller 604, so that the peeling roller 604 can perform the peeling operation.

[0085] Specifically, the press 609 is used to perform a pressing operation on the crops to improve the peeling effect of the crops; 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).

[0086] In an 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 the second 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 the third conveyor belt assembly 707. The output end of the stem discharging roller 705 is drivingly connected to the elevator 702 through the fifth drive chain assembly.

[0087] Specifically, a lifting cavity is formed inside the elevator 702. A lifting channel for transporting agricultural crops (such as corn) is formed in the lifting cavity. An installation bracket for the lower air blower 703 is provided on one side of the elevator 702. The lower air blower 703 is arranged on the installation bracket for the lower air blower 703. The air outlet of the lower air blower 703 is communicated with the lifting cavity for sending air into the lifting cavity. The upper air blower 704 is arranged above the lower air blower 703 and the lower air blower 703 and the upper air blower 704 are respectively located on opposite sides of the elevator 702. The air suction port of the upper air blower 704 is communicated with the lifting cavity for extracting the gas in the lifting cavity outwards. The stem discharging roller 705 is arranged on the elevator 702 and above the upper air blower 704.

[0088] The elevating drive member 701 is connected to the first transmission shaft of the lower blower 703 through a fifth 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 second 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 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 first conveyor belt assembly 706, the upper blower 704, the third conveyor belt assembly 707, the stem discharging roller 705, the fourth 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 first conveyor belt assembly 706 and the third 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, the rotational speed is reduced through the third transmission component and then drives the elevator 702 to rotate, so that the rotational speed of the elevator 702 is adapted to the movement speeds of other components in the hybrid corn harvester, thereby ensuring the harvesting quality of the hybrid corn harvester.

[0089] In the elevator system 7 of this embodiment, the power transmission between the generator 402 and the elevator drive 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 roller 705 is the third-stage power transmission, and the power transmission between the stem roller 705 and the elevator 702 is the fourth-stage power transmission.

The hydraulic pump 403 is also used to pump hydraulic oil to the first hydraulic drive 9.

[0091] Specifically, in this embodiment, the first hydraulic drive 9 can be selected as a hydraulic motor. The first hydraulic drive 9 is arranged on one side of the husk chopper 8, and the first hydraulic drive 9 is connected to the main shaft of the husk chopper 8 through a sixth transmission key (such as a spline), so as to realize the direct connection between the first hydraulic drive 9 and the husk chopper 8. After the first hydraulic drive 9 operates, it drives the main shaft of the husk chopper 8 to rotate, and then the husk chopper 8 performs the husk chopping operation. As can be seen from the above, there is only one stage of power transmission between the husk chopper 8 and the hydraulic pump 403 (or the engine 401). The transmission route is simple, and it also makes the maintenance of the husk chopper 8 more convenient and fast.

[0092] In one embodiment of the present application, as Figure 13 shown, the hybrid corn harvester further includes a grain cleaning blower 10 and a second hydraulic drive 11 that is drivingly connected to the grain cleaning blower 10.

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.

[0094] In an embodiment of the present application, the hybrid corn harvester further includes a header lifting hydraulic drive member 12 for driving the header system 5 to lift, and the hydraulic pump 403 is further configured to pump hydraulic oil to the header lifting hydraulic drive member 12.

[0095] Specifically, in this embodiment, the header lifting hydraulic drive member 12 may be selected as a hydraulic cylinder. The header lifting hydraulic drive member 12 is drivingly connected to the lifting drive end 512 of the header system. The header lifting hydraulic drive member 12 expands and contracts under the pumping action of the hydraulic pump 403, so that the header system 5 can be lifted or lowered, 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-stage power transmission occurs between the lifting drive end 512 of the header system and the hydraulic pump 403 (or the engine 401), which has the advantages of a simple transmission route and low failure rate.

[0096] In an embodiment of the present application, the hybrid corn harvester further includes a third hydraulic drive member 13 for driving the traveling system 1 to steer, and the hydraulic pump 403 is further configured to pump hydraulic oil to the third hydraulic drive member 13.

[0097] Specifically, in this embodiment, the third hydraulic drive member 13 may be selected as a hydraulic cylinder. The third hydraulic drive member 13 is drivingly connected to the rear axle 105 in the traveling system 1. The third hydraulic drive member 13 expands and contracts under the pumping action of the hydraulic pump 403, so that the rear axle 105 moves 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-stage 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).

[0098] In an embodiment of the present application, the hybrid corn harvester further includes a grain tank 14 and a fourth hydraulic drive member 15 for driving the grain tank 14 to flip, and the hydraulic pump 403 is further configured to pump hydraulic oil to the fourth hydraulic drive member 15.

[0099] Specifically, in this embodiment, the grain box 14 is rotatably arranged on the frame of the hybrid corn harvester and is used to collect the crops picked by the hybrid corn harvester. 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 fourth hydraulic driving member 15 can be selected as a hydraulic cylinder. The fourth hydraulic driving member 15 is connected to the grain box 14 and 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-level 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.

[0100] In the present application, since the seed recovery device 3 is driven only when the hybrid corn harvester stops harvesting operations (that is, when the corn cob 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. Thus, the seed recovery device 3 can utilize the idle time of the hydraulic pump 403 to pump hydraulic oil for it.
