Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of power distribution of cross-belt harvesters in soybean and corn compound planting mode, and particularly relates to a power system and method of a soybean and corn combined harvester and the harvester. BACKGROUND

[0002] In recent years, the import volume of soybeans in China increases year by year, and the dependence on foreign countries is high. The harvesting equipment of the soybean and corn combined harvester in China is still mainly mechanical transmission, and the power of the harvesting equipment of the soybean and corn combined harvester is still in a constant power transmission mode in the field, which makes the energy consumption of the soybean and corn combined harvesting equipment always at a high level. In recent years, intelligent machinery has been gradually introduced into agricultural equipment, and the design of intelligent power distribution system has become one of the research directions of intelligent agricultural equipment. Research on intelligent power distribution of agricultural equipment can improve the energy utilization rate of agricultural equipment in China and optimize the production efficiency of agricultural equipment to achieve the effect of energy saving and environmental protection.

[0003] However, there is a lack of research on intelligent power regulation system of soybean and corn combined harvesters in China at present, and intelligent technology is less applied to soybean and corn combined harvesters. The power distribution of soybean and corn combined harvesters is mainly changed by changing the mechanical transmission form and structure, which cannot achieve a good adjustment according to the changes of crop environment and working state. Moreover, the power transmission of existing soybean and corn devices is too complex, and the production is too cumbersome.

[0004] At present, some experts and scholars have carried out related research on the intelligent power regulation of the harvesting equipment of soybeans and corn. Chinese patent CN201310736935.1 discloses a tracked combined harvester power distribution test system, which overcomes the deficiencies and technical defects of field work power distribution test of combined harvesters, and provides a power distribution detection device and method for each working part of the tracked combined harvester in the field under the complex working environment of multiple working conditions. Chinese patent CN205454672U discloses a self-propelled corn harvester power distribution box, which optimizes the structure of the self-propelled corn harvester, the power distribution mode, and the problems such as complex structure, inconvenient installation and maintenance, and poor adaptability.

[0005] The above inventions can all complete the power optimization of the corresponding harvester, but there are still some deficiencies in the power auxiliary energy and safety warning of the soybean and corn combined harvesting machine. The intelligent technology is less applied to the soybean and corn combined harvesting machine, and the power distribution of the soybean and corn combined harvesting machine is mainly changed by changing the mechanical transmission form and structure, which cannot achieve a good adjustment according to the changes of crop environment and working state. During the soybean and corn combined mechanical harvesting process, the growth vigor of soybean and corn changes. When the corn grows well but the soybean grows poorly, the power required by the corn harvesting device and the soybean harvesting device changes constantly, and the machine still works at a fixed power in the "empty load" state, but the existing soybean and corn combined machine lacks an optimization system for the overall power and torque of the corresponding device during the harvesting process, so that the energy consumption of each device is high. SUMMARY

[0006] In view of the above technical problems, the present application provides a power system and method of a soybean and corn combined mechanical harvesting machine and a harvester. The soybean and corn transmission system is improved as a whole, and a self-adaptive power auxiliary energy system suitable for the soybean and corn combined mechanical harvesting machine is designed in combination with the power supply of the original diesel engine system of the machine. When the power required by the soybean and corn harvesting devices changes, the total power of the corn and soybean cutting and harvesting devices is intelligently distributed, achieving the purposes of auxiliary energy and energy saving.

[0007] The total power of the corn and soybean cutting and harvesting devices is intelligently distributed, so that the power of the soybean and corn transportation devices can be distributed according to the amount of the transported materials, so that the amount of harvesting and transportation is matched, and the energy consumption of each transportation and other devices is optimized.

[0008] When the working parts of the harvester are in a low working load or "empty load" state, the original mechanical transmission system provides power and torque to each structure, while the auxiliary energy system can adapt to the power changes of each device of the soybean and corn harvesting machine with different intensities and different densities. The auxiliary energy system determines whether to provide auxiliary energy or recover excess energy, and can provide early warning for each device, improve the energy utilization rate of the soybean and corn harvesting machine, reduce the energy consumption of the soybean and corn harvesting machine, and avoid damage to the device in abnormal working state.

[0024] A harvester comprising the power system of the soybean and corn combined harvesting machine.

[0025] A control method of the power system of the soybean and corn combined harvesting machine, comprising the following steps:

[0026] The power of the planetary power supply system is transmitted to the corn harvesting transmission system and the corn conveying transmission system, the corn conveying transmission system transmits power to the corn peeling transmission system; the power of the planetary power supply system is transmitted to the soybean harvesting transmission system, the soybean harvesting transmission system transmits power to the soybean conveying transmission system, and the soybean conveying transmission system transmits power to the soybean cleaning transmission system.

[0027] The adaptive control system comprises an energy storage mode and an adaptive power supply mode; when the diesel engine alone cannot supply enough power to meet the total power P 总 required by the planetary power supply system, the adaptive control system switches to the adaptive power supply mode, and if the power P1 of the corn harvesting transmission system and / or the power P2 of the soybean harvesting transmission system is lower than the preset value, the adaptive control system increases the power P m of the motor supplied to the planetary power supply system, i.e. the power of the auxiliary power supply system; if the power P1 of the corn harvesting transmission system and / or the power P2 of the soybean harvesting transmission system is higher than the preset value, the adaptive control system reduces the power P m of the motor supplied to the planetary power supply system.

[0028] When the diesel engine alone can supply enough power to meet the total power P 总 required by the planetary power supply system, the adaptive control system switches to the energy storage mode, and the adaptive control system controls the planetary power supply system to convert excess electrical energy into electrical energy of the motor for storage;

The gearbox power input gear 907 is connected to the power output shaft of the adaptive control system 7. The gearbox power input gear 907 is engaged with the second planetary carrier gear 909. The shaft of the second planetary carrier gear 909 is fixedly installed on the second planetary carrier 9010. The second sun gear 906 is engaged with the second planetary gear 905. One end of the shaft of the second planetary gear 905 is installed on the second planetary carrier 9010 through a bearing, and the other end is installed on the first planetary carrier 904 through a bearing and connected to the first planetary gear 903. The first planetary gear 903 is engaged with the first sun gear 902. The shaft of the diesel engine power input gear 908 is connected to the second sun gear 906 and the first sun gear 902 through the shaft of the second planetary carrier gear 909. The shaft of the diesel engine power input gear 908 is not connected to the shaft of the second planetary carrier gear 909 and can rotate freely relative to it. The second sun gear 906 is engaged with the second planetary gear 905. The first sun gear 902 is engaged with the first planetary gear 903. The first planetary gear 903 and the first sun gear 902 are installed in the gear ring 9011. The first planetary gear 903 is engaged with the gear ring 9011 and transmits power to the gear ring power output shaft 901. The gear ring power output shaft 901 is the overall power output shaft, which provides power for the soybean and corn harvesting device. The overall power source of the gear ring power output shaft 901 is the transmission of the motor and the diesel engine, which do not affect each other. However, the diesel engine transmission is the basic power supply method. When the motor transmission stops supplying energy, the diesel engine transmission can transmit energy to the motor and the gear ring power output shaft 901.

[0067] The power output shaft 901 of the planetary power supply system 9 is powered by a motor and a diesel engine; the motor power transmission is through the adaptive power auxiliary motor 701 after the reduction and torque increasing gearbox 702, through the input gear 907 of the gearbox, and engaged with the second planetary carrier wheel 909 to transmit power to the first planetary carrier 904 and the second planetary carrier 9010, and then to the gear power output shaft 901; the diesel power transmission is from the diesel engine to the diesel engine power input wheel 908, which is connected with the first sun gear 902, and the first sun gear 902 is engaged with the first planetary gear 903, which is engaged with the gear 9011, and the power is transmitted to the gear power output shaft 901; the power output shaft 901 is powered by the motor transmission and the diesel engine transmission, and the diesel engine transmission is the basic power supply mode, and when the motor transmission stops supplying power, the diesel engine transmission can transmit power to the motor and the gear power output shaft 901.

[0068] The rotational speed n2 of the gear power output shaft 901, the rotational speed n1 of the first sun gear 902, and the rotational speed n3 of the first planetary gear 903 and the first planetary carrier 904 are related as n3=k1*n1+k 2* n2, where k1 and k2 are related to the number of teeth of the gear and the number of teeth of the sun gear, and the rotational speed can be the same or opposite direction;

[0069] Then according to the torque T=coefficient K*power P / rotational speed n, the diesel engine power and the motor power can be combined to supply power to the whole machine, that is, the total power P 总 required by the device + auxiliary system power P k + auxiliary system power P m ; the power of the diesel engine can also be converted into the electric energy of the motor and the energy required by the mechanical device, that is, the total power P 总 required by the device + auxiliary system power P m = diesel engine system power P k .

[0070] As shown in Figure 8 and 9 , the specific control process is: after the adaptive control system 7 is started, it will first detect whether the power provided by the diesel engine to the planetary power supply system 9 is sufficient; when the diesel engine alone is not enough to meet the total power required by the planetary power supply system 9: the adaptive control system 7 detects whether the power, speed and torque of the soybean and corn device are reduced, and when the power, speed and torque of the soybean and corn device are reduced, the adaptive control system 7 will increase the power output to the planetary power supply system 9; when the power, speed and torque of the soybean and corn device are increased, the adaptive control system 7 will reduce the power output to the planetary power supply system 9;

[0071] If the adaptive control system 7 is started, it will first detect whether the power provided by the diesel engine to the planetary power system 9 meets the power needs of the planetary power system 9. When the diesel engine alone provides power to meet the total power required by the planetary power system 9, the adaptive control system 7 adjusts the planetary power system 9 to convert excess electrical energy into electrical energy of the motor for storage. When the diesel engine provides power to meet the power needs of the planetary power system 9 and the battery is fully charged, the motor directly assists the diesel engine. If the battery is not fully charged, the battery is charged until it is fully charged.

[0072] A harvester comprising the power system of the soybean and corn combined harvester.

[0073] As shown in Figure 4 , 8 and 9, a control method of the power system of the soybean and corn combined harvester, comprising the following steps:

[0074] The power of the planetary power system 9 is transmitted to the corn harvesting transmission system 1 and the corn conveying transmission system 2, and the corn conveying transmission system 2 transmits power to the corn peeling transmission system 3; the power of the planetary power system 9 is transmitted to the soybean harvesting transmission system 8, and the soybean harvesting transmission system 8 transmits power to the soybean conveying transmission system 6, and the soybean conveying transmission system 6 transmits power to the soybean cleaning transmission system 4;

[0075] The adaptive control system 7 comprises an energy storage mode and an adaptive power supply mode; the adaptive control system 7 switches to the adaptive power supply mode or the energy storage mode according to the required power, speed, torque and motor power of the machine;

[0076] When the diesel engine alone is insufficient to meet the total power P 总 required by the planetary power system 9, the adaptive control system 7 switches to the adaptive power supply mode. If the power P1 of the corn harvesting transmission system 1 and / or the power P2 of the soybean harvesting transmission system 8 is lower than the preset value, the adaptive control system 7 increases the power P m of the motor supplied to the planetary power system 9, i.e. the power of the auxiliary power system; if the power P1 of the corn harvesting transmission system 1 and / or the power P2 of the soybean harvesting transmission system 8 is higher than the preset value, the adaptive control system 7 reduces the power P m of the motor supplied to the planetary power system 9;

[0077] When the diesel engine alone provides power to meet the total power P 总 required by the planetary power system 9, the adaptive control system 7 switches to the energy storage mode, and the adaptive control system 7 controls the planetary power system 9 to convert excess electrical energy into electrical energy of the motor for storage;

[0078] When the power provided by the diesel engine to the planetary power supply system 9 meets the power supply needs of the planetary power supply system 9 and the battery of the motor is full, the adaptive control system 7 switches to the adaptive power supply mode, and the motor of the adaptive control system 7 assists the diesel engine to reduce fuel consumption, and if the battery is not full, the battery is charged until it is full, as shown in Figure 9 .

[0079] The energy storage mode of the adaptive control system 7 is that when the power required by the corn harvesting transmission system 1 and the soybean harvesting transmission system 8 is lower than the preset value, the adaptive power assisting motor 701 stops supplying power, and the power supply of the overall machine is only transmitted from the diesel engine power input wheel 908 to the first sun gear 902, and then to the gear ring power output shaft 901; and when the adaptive power assisting motor 701 stops supplying power, the first sun gear 902 will drive the first planet carrier 904, the second planet carrier 9010, and the second planet carrier wheel 909 to rotate, at this time, part of the energy supplied by the diesel engine is converted into mechanical power supply, and the excess energy is converted into electrical energy by the adaptive power assisting motor 701 and stored in the motor power supply 708, so as to achieve the recovery of excess energy, that is, the energy storage mode.

[0080] The adaptive power supply mode of the adaptive control system 7 is that the original diesel engine provides basic power for each device to allow the corn harvesting transmission system 1 and the soybean harvesting transmission system 8 to operate, and after the corn harvesting transmission system 1 and the soybean harvesting transmission system 8 perform the work, the required power changes and the required power is higher than the basic power, that is, when the required power P1+P2=P 总 increases, and P1+P2=P 总 >diesel engine power P k , the adaptive control system 7 adjusts the power motor frequency converter 706 to increase the power P m of the auxiliary power system, when the required power P 总 decreases, the adaptive control system 7 adjusts the power motor frequency converter 706 to reduce the power P m of the auxiliary power system, at this time, the total required power P 总 =P k +P m ; when the required power P 总 ≤diesel engine power P k , the power supply mode is switched to diesel engine power P k supply.

[0081] The adaptive power auxiliary energy system 7 also includes a safety warning mode: when the corn device range finder 1010 and the soybean harrow torque meter 804 cannot detect the required torque T, it is considered that the circuit detection instrument has failed; when the torque T1 of the auger tube 108 and / or the torque T2 of the soybean harvesting harrow 805 is abnormally high compared with the preset value, it is considered that the corn harvesting transmission system 1 and / or the soybean harvesting transmission system 8 encounters a "crop" that cannot be harvested, or foreign matter enters the corn harvesting transmission system 1 and / or the soybean harvesting transmission system 8, and the adaptive control system 7 will suspend the power P of the auxiliary energy system m supply, and apply reverse power to the second planetary carrier wheel 909 through the adaptive power auxiliary energy motor 701 to reduce the output power of the diesel engine power P k .

[0082] In a specific implementation process of the present application:

[0083] When the harvesting machine encounters a harvesting situation where the corn plants grow too little and the soybean plants grow well, the corn harvesting power and transportation power required by the corn harvesting transmission system 1 detected by the corn device range finder 1010 decreases, and the corn device range finder 1010 feeds back the collected parameters to the adaptive control system 7, which controls the power motor frequency converter 706 to reduce the power input to the planetary energy supply system 9 by the adaptive power auxiliary energy motor 701, so as to reduce the power loss. If there are only soybean plants, the corn device range finder 1010 will feed back the collected parameters to the adaptive control system 7, which will control the power motor frequency converter 706 to stop the power input to the planetary energy supply system 9 by the adaptive power auxiliary energy motor 701, at which time the power of the engine will drive the adaptive power auxiliary energy motor 701 to rotate to charge the motor power supply 708, so as to reduce the power loss.

[0084] When the harvesting machine encounters a harvesting situation where the corn plants grow too little and the soybean plants grow well, the corn harvesting power and transportation power required by the corn harvesting transmission system 1 detected by the corn device range finder 1010 decreases, and the corn device range finder 1010 feeds back the collected parameters to the adaptive control system 7, which controls the power motor frequency converter 706 to reduce the power input to the planetary energy supply system 9 by the adaptive power auxiliary energy motor 701, so as to reduce the power loss. If there are only soybean plants, the corn device range finder 1010 will feed back the collected parameters to the adaptive control system 7, which will control the power motor frequency converter 706 to stop the power input to the planetary energy supply system 9 by the adaptive power auxiliary energy motor 701, at which time the power of the engine will drive the adaptive power auxiliary energy motor 701 to rotate to charge the motor power supply 708, so as to reduce the power loss.

[0085] When there is no soybean and corn plant, at this time for energy storage mode, adaptive power auxiliary motor 701 stop working, the power of diesel engine drives the motor and each device operation, most of the power will be through the adaptive power auxiliary motor 701 and store excess energy to motor power supply 708, the remaining energy is just enough for the basic operation of other structures, until the corn device range finder 1010 and soybean rake meter 804 again feel the change, the adaptive power auxiliary motor 701 will start to work auxiliary energy;

[0086] When encountering hard stone, trees and other crops that cannot be harvested, the power and torque required by the device are too large, this condition is considered as abnormal operation, the adaptive power system will provide low power or stop power to the soybean and corn harvesting device, to ensure that the structure of the harvesting device is not damaged; When the transport device encounters stone and other foreign matter, it will also cause the power supply of the transport device to abnormally increase, and the adaptive power system will also provide low power or stop power to the soybean and corn transport device, to ensure that the transport device is not damaged.

[0087] When the soybean and corn harvesting machine harvests, the transmission power and torque required by the soybean harvesting rake 805 and the corn harvesting device on the rake plate 103 will change when the density of soybean and corn plants changes, and the adaptive control system 7 adjusts the adaptive power provided by the harvesting device according to the required transmission power and torque; The soybean and corn transport mechanism is equipped with corresponding raking wheels and augers, and the amount of material transported by the conveying device changes, so that the power and torque required by the conveying device are different, and the adaptive power auxiliary system can provide matching power for the conveying device according to the power required by the transport mechanism.

[0088] The adaptive power auxiliary system suitable for soybean and corn combined harvesting machinery is designed by improving the overall transmission system of soybean and corn and combining the power supply of the original diesel engine system of the machinery, when the density and growth of crops change during the harvesting of soybean and corn, the power required by the harvesting device of soybean and corn changes, the total power of the cutting and harvesting device of soybean and corn is intelligently distributed, and the purpose of auxiliary energy and energy saving is achieved.

[0089] The application provides a low-energy self-adaptive power auxiliary system for a soybean and corn harvesting and transporting device. The system solves the problem that the existing soybean and corn harvesting mechanical power system still provides power to the soybean and corn harvesting device at a fixed power when the crop density changes and the harvesting is in an "empty load" state, which makes the overall harvesting device energy consumption high. The system also solves the problem that the crop transporting device also runs at a fixed power in an "empty load" state, which makes the transporting device energy consumption high, and reduces the energy consumption of the original mechanical transmission system. The system is also provided with a safety warning. When foreign matter enters the harvesting device or the transporting device, the power and torque required by the harvesting system will be abnormal, the self-adaptive power auxiliary system will upload the parameter abnormality to the central control information platform and stop the abnormal device, so as to avoid the damage of the mechanical structure and facilitate the maintenance of the operator.
