[0032] If it is greater, the backflush according to the first backflush control signal is interrupted and the backflush is executed according to the second backflush control signal.

[0033] Furthermore, the method further comprises:

[0034] When the number of times the cooling fan is controlled to perform backblowing exceeds a preset number threshold, if within a preset time window, the water temperature value is still greater than the first preset threshold or the hydraulic oil temperature value is still greater than the second preset threshold, an alarm signal is generated.

[0050] 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. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different 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, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0051] Research has found that harvesters refer to mechanical equipment used for harvesting crops. In terms of application, their working environment is a complex and harsh environment, generally characterized by dust, bran, high temperature, humidity, and strong vibration. As the power source of harvesters, the heat dissipation performance of the engine is particularly important. The air inlet of the engine cooling fan is a screen structure, which is easily blocked during harvesting operations in a hot and dusty environment, resulting in poor heat dissipation.

[0052] The prior art uses a method of manually cleaning the air inlet at a fixed time or mechanically designing a method of cleaning the air inlet, such as using a rotating brush to sweep. This simple cleaning method cannot promptly and effectively remove debris blocking the air inlet, which can easily cause the engine to overheat.

[0053] Based on this, an embodiment of the present application provides a dust removal control method in a harvesting machinery, which can effectively remove debris blocking the air inlet and reduce the risk of engine overheating by controlling the cooling fan of the engine in the harvesting machinery to perform backblowing.

[0054] See also Figure 1 and Figure 2 , Figure 1 This is a flow chart of a dust removal control method in a harvesting machine provided in an embodiment of the present application. Figure 2 Schematic diagram of the structure of a harvesting machine provided in the embodiment of the present application. The dust removal control method provided in the embodiment of the present application is applied to a controller in a harvesting machine. Figure 2 As shown in , the harvesting machine includes a manual switch, a working clutch state, a water temperature sensor, a hydraulic oil temperature sensor, a fan back-blowing solenoid valve output, a display screen and a controller.

[0055] like Figure 1 As shown in , the method includes:

[0056] S101, determining the harvesting operation status of the harvester.

[0057] In this step, the controller can determine the harvesting operation status through the status of each working clutch in the harvester. The main clutch in the harvester is the power master control, the header clutch manages the harvesting parts, and the unloading clutch is dedicated to unloading grain.

[0058] In a possible implementation, step S101 may include:

[0059] When the main clutch, the bridge clutch and the grain unloading clutch of the harvesting machinery are all in a disengaged state, the harvesting operation status is determined to be not operating; when at least one of the main clutch, the bridge clutch and the grain unloading clutch of the harvesting machinery is in a engaged state, the harvesting operation status is determined to be in operation.

[0060] S102: When it is determined that the harvesting operation state is in operation, start the operation timing, and generate an automatic backflush control signal according to the temperature parameter information of the harvesting machine.

[0061] The temperature parameter information includes the parameter value of the temperature parameter and / or the change information of the parameter value. More specifically, the temperature parameter includes the engine water temperature and the hydraulic oil temperature.

[0062] In a possible implementation, step S102 may include:

[0063] Step a1: Continuously monitor the water temperature and hydraulic oil temperature.

[0064] Step a2: when the water temperature value is greater than the first preset threshold value or the hydraulic oil temperature value is greater than the second preset threshold value, an automatic back-blowing control signal is generated to control the cooling fan to perform back-blowing.

[0065] Step a3: After the backblowing of the cooling fan is completed, wait for a preset period.

[0066] Step a4: In response to the end of the preset cycle, within the preset time window, determine whether the water temperature value is still greater than the first preset threshold or whether the hydraulic oil temperature value is still greater than the second preset threshold.

[0067] Step a5: If the water temperature is still greater than the first preset threshold or the hydraulic oil temperature is still greater than the second preset threshold, an automatic backwash control signal is generated again to control the cooling fan to perform backwash again.

[0068] Step a6, after the cooling fan's backblowing ends, wait for the preset period again; and in response to the end of the preset period, determine whether the water temperature is still greater than the first preset threshold or the hydraulic oil temperature is still greater than the second preset threshold within the preset time window; that is, loop through the above steps a2 to a4 until the water temperature is less than or equal to the first preset threshold and the hydraulic oil temperature is less than or equal to the second preset threshold, then return to the step of continuously monitoring the water temperature and the hydraulic oil temperature, that is, the above step a1.

[0069] In one example, when the vehicle operation status is met (the harvesting operation status is in operation), if the water temperature is greater than 92°C or the hydraulic oil temperature is greater than 85°C, the first backflush is performed; after the first backflush, wait for 30 seconds, and continuously monitor the water temperature and hydraulic oil temperature during the 31st-35th second period. If the water temperature is still greater than 92°C or the hydraulic oil temperature is still greater than 85°C during the 31st-35th second period, the second backflush is performed. Otherwise, it goes to the starting point and waits for re-triggering;

[0070] After the second backflush is completed, a 5-minute countdown will begin. If the water temperature is ≤92°C and the hydraulic oil temperature is ≤85°C during this period, the countdown will end and the system will return to the starting point to wait for re-triggering. If the water temperature is still greater than 92°C or the hydraulic oil temperature is still greater than 85°C after 5 minutes, the third backflush will be executed.

[0071] After the third backblowing, if the temperature still does not drop, the fourth, fifth, sixth, ... nth backblowing will be performed for 5 minutes; otherwise, the system will return to the starting point and wait for re-triggering.

[0072] Furthermore, when the number of times the cooling fan is controlled to perform backblowing exceeds a preset number threshold, if within a preset time window, the water temperature value is still greater than the first preset threshold or the hydraulic oil temperature value is still greater than the second preset threshold, an alarm signal is generated.

[0073] Corresponding to the above example, after the fourth backflush: timing is 30s. If the water temperature is still greater than 92℃ or the hydraulic oil temperature is greater than 85℃ after 30s, an alarm signal is generated and a message alarm is sent to the instrument. After the alarm, the alarm needs to be lifted after the water temperature is ≤92℃ and the hydraulic oil temperature is ≤85℃.

[0074] The alarm prompt output can be a CAN message sent to the display screen, which can be used for text and animation prompts on the screen through bus communication; or it can be replaced by a hard-wired signal sound and light alarm, which can be connected to the sound and light alarm through hard wires to provide sound and light prompts.

[0075] In another possible implementation, when the temperature parameter information is information about changes in parameter values ​​of temperature parameters, step S102 may include:

[0076] Step b1, continuously monitor the water temperature and hydraulic oil temperature.

[0077] Step b2: when the water temperature value is greater than the third preset threshold, read the change information of the water temperature value in real time.

[0078] Step b3: when the hydraulic oil temperature value is greater than the fourth preset threshold, read the change information of the hydraulic oil temperature value in real time.

[0079] Step b4: when the water temperature change information and / or the hydraulic oil temperature change information indicate that the temperature rise value in the preset temperature rise window is greater than the preset temperature rise threshold, an automatic backwash control signal is generated to control the cooling fan to perform backwash.

[0080] Here, the controller monitors the changes in water temperature and hydraulic oil temperature in real time to determine the temperature rise. It should be noted that under normal conditions, the water temperature and hydraulic oil temperature change slowly, which is a slow change process. When there is a lot of dust, it will seriously affect the heat dissipation system, causing the temperature to rise faster.

[0081] In one example, after detecting that the water temperature is greater than 65°C, the water temperature change is read in real time. When the change is less than 5°C within 3 minutes, the temperature rise rate is considered normal. When the temperature rise changes by more than 5°C within 3 minutes, it is determined that the temperature rise is too fast, and the air intake system is deemed to be blocked, requiring backblowing to remove dust. After detecting that the hydraulic oil temperature is greater than 40°C, the oil temperature change is read in real time. When the change is less than 5°C within 3 minutes, the temperature rise rate is considered normal. When the temperature rise changes by more than 5°C within 3 minutes, it is determined that the temperature rise is too fast, and the air intake system is deemed to be blocked, requiring backblowing to remove dust.

[0082] In this way, the embodiment of the present application can make a logical judgment by determining the temperature rise, and perform backblowing to remove dust when a rapid temperature rise is determined, which can effectively avoid the lagging measures of processing after the temperature is too high, thereby increasing the processing rate and better protecting the system to prevent overheating.

[0083] In another possible implementation, when the temperature parameter information is information about changes in parameter values ​​of temperature parameters, step S102 may further include:

[0084] Step c1: predicting the change trend of the parameter value of the temperature parameter according to the change information of the parameter value of the temperature parameter of the harvesting machinery.

[0085] Step c2: when the change trend indicates that after the prediction period, the water temperature value will be greater than the first preset threshold or the hydraulic oil temperature value will be greater than the second preset threshold, an automatic backwash control signal is generated to control the cooling fan to perform backwash.

[0086] Here, based on the change information of the parameter values ​​of the temperature parameters of the harvesting machinery, that is, the historical changes, the change trend of the parameter values, that is, the future changes, can be predicted.

[0087] When the change trend indicates that after a shorter prediction period, the water temperature value will be greater than the first preset threshold or the hydraulic oil temperature value will be greater than the second preset threshold, the generation of an automatic backwash control signal can be triggered to control the cooling fan to perform backwashing. This can also effectively avoid the lagging measures of processing after the temperature is too high, thereby improving the processing rate and better protecting the system to prevent overheating.

[0088] S103 , in response to the operation timing reaching a preset period, generating a timed backflush control signal.

[0089] In this step, the operation timing can be started from the time when the vehicle operation status is met, and the timing can be suspended when the vehicle operation status is not met; the preset cycle can be set as needed, for example, a backflush control signal is timed with a cycle of 20 minutes to perform a backflush.

[0090] S104 . Generate a manual backflush control signal in response to a received fan backflush signal triggered manually.

[0091] In the embodiment of the present application, the manual triggering method can adopt a self-recovering rocker switch or a panel with a CAN bus communication method, and backblowing can be manually started.

[0092] In one example, when the controller is powered on and receives a manual fan blowback switch signal, the fan blowback solenoid valve and the enable solenoid valve are immediately energized. If the manual trigger signal is ≤5s, the fan blowback solenoid valve and the enable solenoid valve are energized for 5s; if the trigger signal is greater than 5s≤10s, the pressing time is executed; if the trigger signal is greater than 10s, the fan blowback solenoid valve and the enable solenoid valve are energized for 10s.

[0093] S105. Control a cooling fan of an engine in the harvesting machine to perform backblowing according to the automatic backblowing control signal and / or the timed backblowing control signal and / or the manual backblowing control signal.

[0094] In this step, the controller controls the execution of backflush according to the corresponding control strategy based on the received first backflush control signal, and clears the operation timer, that is, after any condition in manual, automatic, or timing triggers backflush, the timer is cleared.

[0095] In the process of backblowing, in response to the newly received second backblowing control signal, it is determined whether the priority of the second backblowing control signal is greater than that of the first backblowing control signal; if greater, the backblowing according to the first backblowing control signal is interrupted and the backblowing according to the second backblowing control signal is switched. The priority of the manual backblowing control signal is higher than that of the automatic backblowing control signal, and the priority of the automatic backblowing control signal is higher than that of the timed backblowing control signal. The first backblowing control signal and the second backblowing control signal include an automatic backblowing control signal, a timed backblowing control signal and a manual backblowing control signal.

[0096] For example, during the automatic backflush process, if a manual backflush control signal is received (for example, a manual fan backflush switch signal is received, or a manual fan backflush signal CAN message is received), manual backflush is performed, and after the timing is completed, the timing is set to 30S to enter timing or automatic.

[0097] A dust removal control method in a harvesting machinery provided in an embodiment of the present application, combined with the harvesting operation status of the harvesting machinery, provides multiple automatic, timed and manual methods to control the engine's cooling fan to perform backblowing, effectively clears debris blocking the air inlet and reduces the risk of engine overheating; among them, the manual control method ensures subjective operability, the timed control method ensures the frequency of timed cleaning, and the automatic control method based on the parameter value of the temperature parameter and the parameter value change information ensures the timeliness of backblowing in the event of high temperature.
