Description

Technical Field

[0001] The present application relates to the field of agricultural machinery, and in particular to a hybrid power mode trencher. Background Art

[0002] In recent years, with the rapid growth of population and the increasing pressure on the ecological environment, human beings are facing tremendous pressure to survive. The rapid development of agricultural machinery and equipment has brought many problems in energy and environment, and mobile source pollution has become an important source of urban air pollution. Faced with severe challenges, seeking a reasonable balance between environmental protection and work efficiency has become a key issue in the research and development of trenchers. Hybrid trenchers have ushered in vigorous development under this background.

[0003] At present, agricultural trenchers are still mainly powered by traditional energy, and there is still a blank in the research and development of hybrid power intelligent trenchers. Most traditional agricultural trenchers are driven by a single power source (such as an internal combustion engine). When operating in complex terrain or hard soil conditions, such equipment often suffers from insufficient power and low efficiency. In addition, single fuel-powered trenchers consume a lot of fuel and cause serious emissions pollution during use, which is not conducive to the sustainable development of agriculture.

[0004] With the development of new energy technologies, hybrid power technology has been gradually applied to various types of mechanical equipment. The hybrid power mode combines the advantages of internal combustion engines and electric motors, and can adjust the power output according to actual needs, thereby achieving energy conservation and emission reduction while ensuring operating efficiency. However, the hybrid power mode for agricultural trenchers in the prior art has not been fully studied and applied, especially how to switch power modes under different terrain and soil conditions to improve trenching efficiency and adaptability, which is still a problem to be solved. Therefore, the present invention combines the third-generation photovoltaic technology to develop a hybrid power mode trencher. Summary of the invention

[0005] The purpose of this application is to provide a hybrid power trencher that can be used in different scenarios through multiple modes, thereby improving trenching efficiency, saving fuel and protecting the environment.

[0006] To achieve the above objectives, this application provides the following solutions:

[0007] In a first aspect, the present application provides a hybrid power mode trencher, comprising: a power switching device, an engine group device, an electric motor group device and an execution device;

[0008] The power switching device is used to switch the first power mode, the second power mode or the third power mode, and control the engine group device to generate the first power in the first power mode; control the motor group device to generate the second power in the second power mode; and control the engine group device and the motor group device to jointly generate the third power in the third power mode;

[0009] The execution device is used to perform trenching according to the first power, the second power or the third power.

[0010] According to the specific embodiments provided in this application, this application has the following technical effects:

[0011] The present application provides a hybrid power mode trencher, which cooperates with a power switching device, an engine unit device and an electric motor unit device to switch different modes according to different scenarios of the trencher. It can be switched to the first power mode when the terrain is relatively flat and the soil is soft, and it can be switched to the second power mode when the terrain is relatively complex and the soil is relatively hard. When the terrain is extremely complex and the soil is extremely hard, it can be switched to the third power mode. The hybrid power mode intelligent trencher can be applied to different scenarios, saving fuel and protecting the environment. The present application improves the efficiency of trenching by switching between multiple modes, and the addition of the electric motor unit saves energy resources, reduces energy pollution, and protects the environment.

[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] In order to make the purpose, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] In an exemplary embodiment, Figure 1 As shown, a hybrid power mode trencher is provided, and the hybrid power mode trencher includes: a power switching device 1, an engine group device 2, an electric motor group device 3 and an execution device. The power switching device 1 receives the mode selected by the user and switches the power mode according to the mode selected by the user. The user can switch the mode according to the terrain conditions based on experience to meet the needs of different working environments and ensure efficient operation under different terrain and soil conditions.

[0019] One end of the engine group device 2 and one end of the motor group device 3 are both connected to the power switching device 1; the other end of the engine group device 2 and the other end of the motor group device 3 are both connected to the execution device.

[0020] The power switching device 1 is used to switch between the first power mode, the second power mode or the third power mode, and controls the engine group device 2 to generate the first power in the first power mode; controls the motor group device 3 to generate the second power in the second power mode; and controls the engine group device 2 and the motor group device 3 to jointly generate the third power in the third power mode.

[0021] The execution device is used to perform trenching according to the first power, the second power or the third power. The engine group device 2 is connected in parallel with the motor group device 3, and can drive the trenching machine to work respectively.

[0022] The power switching device 1 is the core control unit of the trenching machine, which is connected to the engine unit 2 and the motor unit 3 through a communication cable, and is used to send instructions to control the power output of the engine unit 2 and the motor unit 3 according to different working conditions and requirements. These modes usually include the first power mode, the second power mode or the third power mode. The second power mode is the electric mode, which is a low-power mode and is used under normal starting and low power. In the second power mode, only the motor unit 3 works and the engine unit 2 stops running, which is suitable for low-speed driving or short-distance operation, and can reduce fuel consumption and noise. The first power mode is the oil-powered mode, which is a medium-powered mode and is suitable for the trenching machine to work at a stable power. In the first power mode, only the engine unit 2 works and the motor unit 3 stops running, which is suitable for high-speed driving or working conditions requiring high power output. The third power mode is the oil-electric hybrid mode, which is a high-power mode, and the high-power mode is used in complex terrain, muddy roads, and hard soil. In the third power mode, the engine unit 2 and the motor unit 3 work together to optimize power output and improve fuel efficiency and power performance.

[0023] In another exemplary embodiment of the present application, the execution device includes: a first clutch 4, a second clutch 5, a transmission group device, a power transmission system 6 and a trenching tool device 7.

[0024] One end of the first clutch 4 is connected to the engine group device 2; one end of the second clutch 5 is connected to the motor group device 3; the other end of the first clutch 4 and the other end of the second clutch 5 are both connected to one end of the transmission group device; the other end of the transmission group device is connected to the power transmission system 6; the power transmission system 6 is connected to the trenching tool device 7.

[0025] The first clutch 4 is used to engage in the first power mode or the third power mode and transmit the first power or the third power to the transmission group device.

[0026] The second clutch 5 is used to engage in the second power mode or the third power mode and transmit the second power or the third power to the transmission group device. The first clutch 4 and the second clutch 5 are used to switch the power mode.

[0027] The transmission group device is used to generate a first torque, a second torque or a third torque according to the first power, the second power or the third power.

[0028] The power transmission system 6 is used to transmit the first torque, the second torque or the third torque to the trenching tool device 7 to perform trenching.

[0029] In another exemplary embodiment of the present application, the engine assembly device 2 includes: a fuel tank, an engine and an engine controller.

[0030] One end of the engine controller is connected to the power switching device 1; the other end of the engine controller is connected to the first clutch 4 and the engine respectively; the engine controller is used to start the engine under the control of the power switching device 1 and engage the first clutch 4. At this time, the second clutch 5 is disconnected, and the control accuracy of the clutch directly affects the smoothness of power switching and the overall efficiency of the trencher.

[0031] The engine is connected to the oil tank, and is used to generate a first power according to the fuel stored in the oil tank. The engine is provided with the first power by an internal combustion engine.

[0032] In another exemplary embodiment of the present application, the motor group device 3 includes: a photovoltaic battery pack, a motor and a motor controller.

[0033] The motor controller is connected to the photovoltaic battery pack, the motor and the power switching device 1 respectively; the motor is connected to the second clutch 5 .

[0034] The photovoltaic battery pack is used to absorb solar energy and convert it into electrical energy, and the motor controller is powered by the electrical energy, and the motor controller is powered by the electrical energy to extend the working time of the photovoltaic battery pack. The photovoltaic battery pack provides stable power to the motor controller and the motor through an inverter. The photovoltaic battery pack is mounted on the top of the trencher or in a suitable position, and contains high-efficiency photovoltaic components and power management modules inside to provide green energy for the motor. Due to the working environment, climate conditions, energy-saving and emission reduction policies of the trencher, the trencher does not need to be equipped with a fast charging port. The advantage of the fast charging port is that it reduces the charging time. However, if you want to fully charge the battery in the shortest possible time, you have to increase the charging voltage or charging current, which may cause certain pressure on rural electricity use. The third-generation photovoltaic battery panel is installed on the trencher. Among them, the photovoltaic battery pack has higher conversion efficiency, lower cost, and more convenient application. The technical guarantee for low cost is that the "gasification plating" method can be adopted, which can save materials and can be mass-produced. The technical guarantee for high efficiency is that the "multi-junction" semiconductor method can be adopted to improve the photoelectric conversion efficiency. In order to improve the efficiency of sunlight utilization, semiconductors with different "nodules" are produced. The "spectral effect range" of the semiconductors is different. They are combined to make "multi-junction semiconductors"; such a combination, a "multi-junction solar cell", will have a "wider spectral effect range" for incident light, which can improve the conversion efficiency of the solar cell.

[0035] The motor controller is used to start the motor under the control of the power switching device 1. The motor is used to generate the second power according to the electric energy under the control of the motor controller and engage the second clutch 5. At this time, the first clutch 4 is disconnected to avoid engine idling and reduce energy loss.

[0036] In another exemplary embodiment of the present application, the hybrid mode trencher further includes: a speed switching device connected to one end of the transmission group device, for switching different gears of the transmission group device. The speed switching device 1 receives a mode selected by a user and switches the power mode according to the mode selected by the user.

[0037] The transmission group device adjusts the magnitude of the first torque, the second torque or the third torque according to the different gears. The transmission group device adjusts the speed and torque of the power output through different gear combinations to adapt to different driving speeds and load conditions. The reasonable design of the transmission group device can improve the overall efficiency and fuel economy of the system.

[0038] In another exemplary embodiment of the present application, the transmission group device includes: a transmission and a transmission controller.

[0039] One end of the transmission is connected to the first clutch 4 and the second clutch 5; the other end of the transmission is connected to the power transmission system 6; the transmission is used to generate a first torque, a second torque or a third torque according to the first power, the second power or the third power, and transmit it to the power transmission system 6. The transmission is also used to adjust the forward speed and power output of the trencher to adapt to different working conditions of the trencher.

[0040] One end of the transmission controller is connected to the transmission; the other end of the transmission controller is connected to the speed switching device; the transmission controller is used to adjust the size of the first torque, the second torque or the third torque according to different gears.

[0041] The other end of the transmission controller is connected to the speed switching device via a communication cable.

[0042] In another exemplary embodiment of the present application, the transmission includes: a sun gear, planetary gears, a planetary gear carrier and a ring gear.

[0043] The planetary gears are meshed with the sun gear and the ring gear respectively, and the planetary gears are mounted on a planetary gear carrier; the sun gear is connected to the first clutch 4 and the second clutch 5 respectively; and the planetary gear carrier is connected to the power transmission system 6.

[0044] In the transmission, multiple planetary gears realize the power distribution of the engine and the motor through the interaction of the sun gear, the planetary gear carrier and the ring gear, and both the engine and the motor drive the sun gear. In the first power mode, the motor drives the sun gear to rotate, and the multiple planetary gears rotate around the sun gear and drive the planetary gear carrier to rotate. If the ring gear is fixed, the planetary gear carrier serves as the output and transmits the output torque to the trenching tool device 7 through the power transmission system 6. In the second power mode, the engine drives the sun gear to rotate, and the multiple planetary gears rotate around the sun gear and drive the planetary gear carrier to rotate. If the ring gear is fixed or has a certain rotation constraint, the planetary gear carrier serves as the output to realize power transmission. In the third power mode, the engine and the motor drive the sun gear at the same time, and the power of the two is added. The multiple planetary gears rotate under the joint action of the power of the two and transmit the power to the planetary gear carrier or the ring gear. By controlling the ring gear (such as making it rotate freely, locking it or applying a certain resistance), the output ratio of the torque can be adjusted to realize torque distribution. The present application realizes the coupled output of the first power and the second power through the cooperation of multiple planetary gears through the sun gear, the planetary gear carrier and the ring gear, and further realizes the coupling or independent output of the power generated by the engine and the power generated by the motor through the gear ratio.

[0045] In another exemplary embodiment of the present application, the hybrid mode trencher further includes: a differential, a left drive wheel and a right drive wheel. The differential is used to balance the output shaft power of the left drive wheel and the right drive wheel to ensure stable operation.

[0046] The differential is respectively connected to the power transmission system 6, the left drive wheel and the right drive wheel, and the differential is used to distribute the first torque, the second torque or the third torque to the left drive wheel and the right drive wheel; the left drive wheel and the right drive wheel jointly drive the trencher according to the distributed torque.

[0047] In another exemplary embodiment of the present application, the hybrid mode trencher further includes: a transmission shaft.

[0048] The transmission shaft is connected to the power transmission system 6 and the trenching tool device 7 respectively, and the transmission shaft is used to transmit the first torque, the second torque or the third torque to the trenching tool device 7.

[0049] In another exemplary embodiment of the present application, the power transmission system 6 of the present application not only connects the transmission and the drive shaft, but also connects the engine / motor and the transmission. Its main functions include: Power transmission: efficiently transmitting the power of the engine or motor to the transmission and the drive shaft. Torque distribution: reasonably distribute the torque generated by the engine and the motor according to the working conditions to ensure the smoothness of the power output. Torque amplification: in some cases, the power transmission system 6 can amplify the torque through the transmission to meet the high torque requirements of heavy machinery such as trenchers.

[0050] In another exemplary embodiment of the present application, the hybrid mode trencher also includes: an intelligent control module. The intelligent control module is composed of a sensor group, a control chip and a display and interaction unit. The intelligent control module is used to monitor the working status and external environment of the trencher in real time, and adjust the power mode according to preset parameters or manual instructions. And intelligently select the optimal power mode according to the battery power, engine load and equipment operation status. The sensor group monitors torque, speed, load and terrain characteristics; the control chip is based on the Advanced RISC Machines (ARM) or Field Programmable Gate Array (FPGA) architecture to process sensor data and send power mode instructions; the display and interaction unit can monitor the device status through the touch screen by the user and switch different modes according to manual instructions. Through the intelligent control module, the present application can enable the trencher to switch between different power modes according to parameters such as terrain complexity and soil hardness, and automatically optimize the operation strategy of the trencher, so as to achieve efficient operation while reducing fuel consumption and environmental pollution, and improve the intelligence and accuracy of agricultural management.

[0051] The first power mode of this application is suitable for flat and soft terrain. The working principle is that the photovoltaic battery pack supplies power to the motor, and the motor drives the transmission shaft through the transmission. The sun gear of the transmission is driven by the motor, and the engine is in the off state. The second clutch 5 is locked to the motor alone.

[0052] The second power mode is suitable for scenes with more complex terrain or harder soil. The working principle is that the engine starts, and the power enters the transmission through the main output shaft to drive the power transmission system 6. The sun gear of the transmission is driven independently by the engine, and the motor is on standby. Switch the first clutch 4 to engine drive.

[0053] The third power mode is suitable for extremely complex or hard soil scenarios. The working principle is that the engine and the motor run simultaneously, the engine provides high torque output, and the motor provides instantaneous high power. The transmission realizes the coupled output of the two powers. The intelligent control module dynamically monitors the load and adjusts the power distribution ratio of the engine and the motor in real time.

[0054] This application is driven by the synergy of fuel and electricity. It combines the power output of traditional gasoline engines and electric motors to achieve a unique conversion and switching mechanism. When the engine is running, it can not only provide support for power output, but also supply energy to the electric motor through the photovoltaic battery pack. In the hybrid trencher, the engine and the electric motor work together to ensure that the trencher is always in the best condition.

[0055] The trencher in this application is a parallel hybrid agricultural trencher, that is, the engine and the motor can drive the trencher to work separately. Its advantage is that the engine and the motor will use multiple planetary gears, sun gears, planetary gear carriers and gear rings to cooperate with each other to complete power coupling. The parallel hybrid agricultural trencher is based on the powertrain composed of the engine and transmission of the traditional agricultural trencher, and a set of photovoltaic battery packs and electric motors are added to the powertrain, and the two jointly drive the agricultural trencher to work. The parallel hybrid agricultural trencher is mainly composed of an engine, a transmission, a suspended chassis, an electric motor, a photovoltaic battery pack, a drive shaft, a fuel tank, etc. The trencher mainly uses No. 0 diesel as its main energy source. The agricultural trencher reserves some space at the location where the engine is installed for installing the photovoltaic battery pack, which mainly transmits power from the installed third-generation photovoltaic panels. The suspension chassis uses a "massive" amount of aluminum alloy parts. All control arms, bearing seats (also called steering knuckles), and brake calipers are made of aluminum alloy, which can greatly reduce the unsprung mass and improve the suspension response speed and the overall ground-keeping performance of the trencher. At the same time, a standard steel subframe is used, which is welded to form a full-frame structure. The thick anti-roll bar is matched with the shock absorber with very light damping, which makes the trencher work faster.

[0056] This application combines the advantages of the engine and the electric motor, and has the following advantages: First, fuel consumption is reduced in the first power mode, and power output is optimized in the third power mode, which improves fuel economy and achieves energy saving and high efficiency. Secondly, zero emissions in the first power mode and reduced tail gas emissions in the third power mode achieve environmental protection. In addition, the engine and the electric motor work together to provide higher power and torque output, and the power is strong. Furthermore, this application can also adopt intelligent control, using sensors and control chips, and automatically adjusting modes to improve operation accuracy. Finally, this application can flexibly switch between different modes according to different terrains to adapt to a variety of operating environments.

[0057] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

The description of the above embodiments is only used to help understand the method and core ideas of this application. At the same time, for those skilled in the art, according to the ideas of this application, there will be changes in the specific implementation methods and application scope.
