[0002] During the operation of agricultural harvesting machinery, the engine power needs to be transmitted to various working parts to achieve efficient harvesting and processing of crops. As a key component of power transmission, the main clutch, its engagement and disengagement state directly determines whether the power can be smoothly transmitted to the working parts. Traditional main clutch control methods usually rely on mechanical structure or simple electrical control. Among them, the mechanical structure control method is usually controlled by a mechanical connecting rod or a joystick, and the electrical control method is usually to send the main clutch working instruction to the vehicle controller through an ordinary button switch, so that the vehicle controller controls the engagement solenoid valve or the disengagement solenoid valve of the main clutch to be energized, and then drives the main clutch to work through the hydraulic cylinder.

[0053] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It should be understood that the drawings in the present application only serve the purpose of explanation and description and are not used to limit the scope of protection of the present application.

In addition, those skilled in the art, under the guidance of the content of the present application, can add one or more other operations to the flowchart, or remove one or more operations from the flowchart.

[0054] In addition, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0055] The following methods, devices, electronic devices or computer-readable storage media of the embodiments of the present application can be applied to any scenario requiring harvesting machinery clutch control. The embodiments of the present application are not limited to specific application scenarios. Any scheme using the control method and device of the harvesting machinery clutch provided by the embodiments of the present application is within the protection scope of the present application.

[0056] It is worth noting that during the operation of agricultural harvesting machinery, the engine power needs to be transmitted to various working parts to achieve efficient harvesting and processing of crops. As a key component of power transmission, the main clutch, its engagement and disengagement state directly determines whether the power can be smoothly transmitted to the working parts. Traditional main clutch control methods usually rely on mechanical structure or simple electrical control. Among them, the mechanical structure control method is usually controlled by a mechanical connecting rod or a joystick, and the electrical control method is usually to send the main clutch working instruction to the vehicle controller through an ordinary button switch, so that the vehicle controller controls the engagement solenoid valve or the disengagement solenoid valve of the main clutch to be energized, and then drives the main clutch to work through the hydraulic cylinder. However, the traditional main clutch control method is difficult to meet the operating requirements of modern agricultural machinery under complex working conditions, reducing the safety and efficiency of the whole machine.

[0057] In response to the above problems, the embodiments of the present application propose a control method and a control device for a harvesting machinery clutch, which realizes adaptive engagement and separation control of the main clutch. It can be widely used in the complex operating environments of various types of harvesting machinery, can actively avoid the risk of misoperation under abnormal conditions, and improve the safety, work efficiency and adaptability of the entire machine to working conditions.

[0058] To facilitate the understanding of the present application, the technical solution provided by the present application is described in detail below in conjunction with specific embodiments.

[0059] See also Figure 1 , Figure 1 This is one of the flow charts of a control method for a harvesting machinery clutch provided in an embodiment of the present application.

[0060] Here, harvesting machinery includes: combine harvesters, cotton pickers and sugarcane harvesters, etc.

[0061] like Figure 1 As shown in the figure, the control method of the harvesting machinery clutch provided in the embodiment of the present application comprises the following steps:

[0062] Step S101, obtaining a state switching signal of a main clutch of the harvesting machinery.

[0063] Here, the main clutch of the harvester is used to control the power transmission and power interruption between the engine and the transmission system of the harvester, thereby indirectly adjusting the operating state of the actuator (such as a cutter, a conveyor, etc.). The state switching signal of the main clutch includes: an engagement signal and a disengagement signal. As an example, Figure 2 As shown in , if the main clutch is in the disengaged state, the operator presses the main clutch switch to generate a main clutch engagement signal; if the clutch is in the engaged state, the operator presses the main clutch switch to generate a main clutch disengagement signal.

[0064] Step S102: If the state switching signal of the main clutch is a connection signal, the main clutch is allowed to be connected and the main clutch is in a disengaged state, then based on the grain bin cover opening and closing state of the harvester, the top auger position and the engine speed, determine whether to connect the main clutch.

[0065] In this step, the main clutch is allowed to engage even if the enabling conditions are valid. Here, the enabling conditions usually include that the whole machine is in normal operation and there are no alarm signals from other components. The main clutch is in a disengaged state, that is, the main clutch engagement state is 0, and the disengaged state means that the main clutch has been separated or is in the process of separation. Among them, in a single-valve system, that is, a single solenoid valve controls the engagement and separation of the main clutch, and the main clutch engagement state corresponds to the state of a single solenoid valve; in a dual-valve system, that is, two solenoid valves control the engagement and separation of the main clutch, the main clutch engagement state represents a virtual concept, and the main clutch engagement state needs to be comprehensively judged by the states of the two solenoid valves.

[0066] Specifically, if the rising edge of the main clutch engagement signal is obtained, the enabling condition is valid and the main clutch engagement state is 0, it is determined whether to engage the main clutch based on the opening and closing state of the grain bin cover, the top auger position and the engine speed of the harvester.

[0067] Here, if Figure 2 As shown in , the controller can obtain the granary cover opening and closing state through the granary cover opening and closing state sensor, obtain the top auger position through the top auger position sensor, and obtain the engine speed through the engine speed sensor. As an example, the controller can be a PLC or an embedded controller, which is not limited here.

[0068] Here, the opening and closing state of the grain bin cover, the position of the top auger and the engine speed of the harvesting machinery affect the safety, operating efficiency and component life of the whole machine. Specifically, if the grain bin cover is not opened and the main clutch is engaged during harvesting, the pressure in the grain bin may increase suddenly, damaging the grain bin sealing structure or causing blockage; if the top auger is not fully engaged and the main clutch is still engaged, it will cause deformation of the mechanical structure; if the engine speed is high and the main clutch is still engaged, it may cause damage to the transmission belt and working parts. Here, as an example, if the harvesting machinery is a combine harvester, the working parts of the combine harvester include: a drum, a fan, a chopper, a grain elevator and a debris elevator, etc.

[0069] Combine the following Figure 3 To illustrate how to determine whether to engage the main clutch based on the opening and closing state of the grain bin cover of the harvester, the position of the top auger and the engine speed.

[0070] See also Figure 3 , Figure 3 This is the second flowchart of a control method for a harvesting machinery clutch provided in an embodiment of the present application.

[0071] like Figure 3 As shown in FIG. 1 , regarding step S102, in a specific implementation, as an example, the following steps may be included:

[0072] Step S1021, if the opening and closing state of the grain bin cover of the harvester is in the open state, the top auger position of the harvester reaches the set position and the engine speed of the harvester is less than or equal to the safety speed threshold, it is determined to engage the main clutch.

[0073] Step S1022, if the granary cover is in the closed state, a granary cover confirmation signal is generated; after the granary cover confirmation signal is generated, it is determined whether a confirmation reply signal of the granary cover is received, and based on the confirmation reply signal reception result of the granary cover, the engine speed and the forced engagement authority of the main clutch, it is determined whether the main clutch is engaged.

[0074] In this step, if Figure 2 As shown in , if the granary cover is in the closed state, the controller sends a granary cover alarm signal to the display screen, i.e., a granary cover confirmation signal. When the operator checks the granary cover confirmation signal, he checks the granary cover. If the operator checks that the granary cover is in the open state, he clicks the display screen to confirm that the granary cover is in the open state, and the controller receives the confirmation reply signal of the granary cover; if the operator checks that the granary cover is in the closed state, the problem of the granary cover or the granary cover-related parts is solved. After solving the problem, it returns to step S101. Among them, a real-time alarm prompt is sent to the operator through the display screen to ensure that the operator can understand the status of the vehicle components in time and take corresponding measures.

[0075] Here, the main clutch forced engagement authority is determined by whether the operator presses the forced engagement switch at the next power-on. The main clutch forced engagement authority is reset each time the power is off to ensure that the normal operating logic can be restored under abnormal conditions. If the operator presses the forced engagement switch at the next power-on, it is determined that the main clutch allows forced engagement; if the operator does not press the forced engagement switch at the next power-on, it is determined that the main clutch prohibits forced engagement.

[0076] Step S1023, if the grain bin cover is in the open state, the main clutch is allowed to separate and the top auger position has not reached the set position, a top auger confirmation signal is generated; after the top auger confirmation signal is generated, it is determined whether a confirmation reply signal of the top auger is received, and based on the confirmation reply signal reception result of the top auger, the engine speed and the forced engagement authority of the main clutch, it is determined whether the main clutch is engaged.

[0077] In this step, if the top auger position has not reached the set position, the controller sends a top auger alarm signal, i.e., a top auger confirmation signal, to the display screen. When the operator checks the top auger confirmation signal, it checks whether the top auger has reached the set position. If the operator checks that the top auger position has reached the set position, the display screen is clicked to confirm that the top auger position has reached the set position, and the controller receives a confirmation reply signal from the top auger. If the operator checks that the top auger has not reached the set position, the problem with the top auger or top auger-related components is resolved. After the problem is resolved, the process returns to execute step S101.

[0078] Combine the following Figure 4 To illustrate how to determine whether to engage the main clutch based on the confirmation reply signal reception result of the grain bin cover, the engine speed and the forced engagement authority of the main clutch.

[0079] See also Figure 4 , Figure 4 This is a third flow chart of a method for controlling a harvesting machinery clutch provided in an embodiment of the present application.

[0080] like Figure 4 As shown in , regarding the determination of whether to engage the main clutch based on the confirmation reply signal reception result of the grain bin cover, the engine speed and the forced engagement authority of the main clutch in step S1023, in specific implementation, as an example, the following steps may be included:

[0081] Step S10221, if a confirmation reply signal from the grain bin cover is received and the engine speed is less than or equal to a safety speed threshold, it is determined that the main clutch is engaged.

[0082] Step S10222: If a confirmation reply signal from the granary cover is received, the engine speed is greater than the safety speed threshold, and the forced engagement authority of the main clutch is to allow forced engagement, it is determined that the main clutch is engaged.

[0083] Step S10223, if a confirmation reply signal from the grain bin cover is received, the engine speed is greater than the safety speed threshold, and the forced engagement authority of the main clutch is to prohibit forced engagement, it is determined that the main clutch remains in a disengaged state.

[0084] Step S10224: if the confirmation reply signal from the grain bin cover is not received, it is determined that the main clutch remains in the disengaged state.

[0085] Combine the following Figure 5 To illustrate how to determine whether to engage the main clutch based on the confirmation reply signal reception result of the top auger, the engine speed and the forced engagement authority of the main clutch.

[0086] See also Figure 5 , Figure 5 This is the fourth flow chart of a method for controlling a harvesting machinery clutch provided in an embodiment of the present application.

[0087] like Figure 5 As shown in , regarding the determination of whether to engage the main clutch based on the confirmation reply signal reception result of the top auger, the engine speed and the forced engagement authority of the main clutch in step S1023, in specific implementation, as an example, the following steps may be included:

[0088] Step S10231: If a confirmation reply signal from the top auger is received and the engine speed is less than or equal to a safety speed threshold, it is determined that the main clutch is engaged.

[0089] Step S10232: If a confirmation reply signal from the top auger is received, the engine speed is greater than a first safety speed threshold, and the forced engagement authority of the main clutch is to allow forced engagement, then determine to engage the main clutch.

[0090] Step S10233, if a confirmation reply signal from the top auger is received, the engine speed is greater than the safety speed threshold and the forced engagement authority of the main clutch is to prohibit forced engagement, it is determined that the main clutch remains in a disengaged state.

[0091] Step S10234: If no confirmation reply signal from the top auger is received, it is determined that the main clutch remains in a disengaged state.

[0092] Regarding steps S10224 and S10234, if the confirmation reply signal of the grain bin cover or the confirmation reply signal of the top auger is not received, it is determined that the main clutch remains in the disengaged state. If the engine speed is greater than the first safety speed threshold at this time, an alarm prompt is sent to the controller, and the controller controls the display screen to display the alarm prompt message "Please reduce the engine speed to the predetermined safety value and re-engage the main clutch". At this time, if the engagement signal of the main clutch continues to be valid, the alarm will continue; if the falling edge of the main clutch engagement signal (that is, the rising edge of the main clutch disengagement signal) is detected, the system will continue to alarm. If the subsequent operator does not press the switch, that is, there is no operation instruction, the alarm state will stop after the set time; if the engine speed drops below the safety speed threshold during the alarm period, the system still does not perform automatic engagement, and returns to execute step S101, that is, wait for a new engagement signal to be triggered and then re-execute the engagement strategy.

[0093] See again Figure 1 In step S103, if the state switching signal of the main clutch is a separation signal and the main clutch is in an engaged state, it is determined whether to separate the main clutch based on the engine speed and the speeds of multiple working parts of the harvesting machinery.

[0094] In this step, the main clutch is allowed to be separated, that is, the enabling condition is valid. The main clutch is in the engaged state, that is, the main clutch engagement state is 1, and the engaged state is that the main clutch has been engaged or is in the process of being engaged. Specifically, if the rising edge of the main clutch separation signal is obtained, the enabling condition is valid and the main clutch engagement state is 1, then based on the engine speed and the speed of multiple working parts of the harvesting machine, it is determined whether to separate the main clutch.

[0095] Combine the following Figure 6 To illustrate how to determine whether to engage the main clutch based on the confirmation reply signal reception result of the top auger, the engine speed and the forced engagement authority of the main clutch.

[0096] See also Figure 6 , Figure 6 This is the fifth flow chart of a control method for a harvesting machinery clutch provided in an embodiment of the present application.

[0097] like Figure 6 As shown in FIG. 1 , regarding step S103, in a specific implementation, as an example, the following steps may be included:

[0098] Step S1031: if the engine speed is less than or equal to the safety speed threshold, determine to disengage the main clutch.

[0099] Step S1032: If the engine speed is greater than the safety speed threshold, the speed of each working component of the harvesting machinery is obtained.

[0100] Step S1033: If each of the plurality of working components has no rotation speed, it is determined to disengage the main clutch.

[0101] Step S1034: if any one of the plurality of working components has a rotation speed, the engine speed is reduced to a fixed speed, and after the speed is reduced, it is determined to disengage the main clutch.

[0102] In this step, if any of the multiple working parts has a rotation speed, a TSC1 (engine speed control) message is sent to the engine, and a separation alarm prompt message is issued at the same time to reduce the engine speed to a fixed speed. If the engine speed is reduced to below the safety speed threshold, the main clutch is disengaged; if the engine speed fails to be reduced to below the safety speed threshold or the current harvesting machinery is in a high throttle state, the main clutch is directly disengaged. The main clutch is disengaged after the engine speed is reduced to a fixed speed in order to ensure safety. Here, the fixed speed is obtained by setting the speed regulation time and setting the speed regulation rate. The high throttle state is when the throttle opening of the engine is large, and the harvesting machinery is in a high speed, high power output working mode.

[0103] In an embodiment of the present application, if it is determined to engage the main clutch, the engagement solenoid valve and the enable solenoid valve corresponding to the main clutch are controlled to continuously operate for a first preset time to engage the main clutch; if it is determined to disengage the main clutch, the disengagement solenoid valve and the enable solenoid valve corresponding to the main clutch are controlled to continuously operate for a second preset time to disengage the main clutch.

[0104] Here, if it is determined that the main clutch is to be engaged, the main clutch engagement state is set to 1; the engagement solenoid valve and the enabling solenoid valve corresponding to the main clutch are controlled to continuously operate for a first preset time, that is, the engagement solenoid valve and the enabling solenoid valve are powered on and then lose power after the first preset time. If it is determined that the main clutch is to be separated, the main clutch engagement state is set to 0; the separation solenoid valve and the enabling solenoid valve corresponding to the main clutch are controlled to continuously operate for a second preset time, that is, the separation solenoid valve and the enabling solenoid valve are powered on and then lose power after the second preset time.

[0105] It should be noted that, during the first preset time period during which the engaging solenoid valve and the enabling solenoid valve corresponding to the main clutch continue to operate, that is, the main clutch is in the engaging process, if a separation signal of the main clutch is received, the engaging solenoid valve and the enabling solenoid valve corresponding to the main clutch stop operating, that is, immediately lose power, and return to execute step S103, that is, the separation strategy.
