During the operation of a harvester, there is a situation where the harvester stalls under load. When the harvester stalls under load and restarts, it needs to overcome a large load, which makes the harvester easy to be damaged. Summary of the invention

[0004] The purpose of the present invention is to at least solve the problem that a harvester with load shuts down and restarts needs to overcome a large load. This purpose is achieved through the following technical solutions:

[0048] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0049] It should be understood that the terms used herein are only for the purpose of describing specific example embodiments and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "one", "an" and "said" as used herein may also be meant to include plural forms. The terms "include", "comprise", "contain", and "have" are inclusive, and therefore specify the existence of stated features, steps, operations, elements and / or parts, but do not exclude the existence or addition of one or more other features, steps, operations, elements, parts, and / or combinations thereof. The method steps, processes, and operations described herein are not interpreted as necessarily requiring them to be performed in the specific order described or illustrated, unless the execution order is clearly indicated. It should also be understood that additional or alternative steps may be used.

[0050] Although the terms first, second, third, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the first element, component, region, layer or section discussed below can be referred to as the second element, component, region, layer or section without departing from the teaching of the example embodiments.

[0051] For ease of description, spatial relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure is turned over, then the elements described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." can include both upper and lower orientations. The device can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.

[0052] A harvester is an agricultural machine used for harvesting crops. The crops that a harvester can harvest include but are not limited to wheat, corn, soybeans, sorghum, millet, rapeseed and quinoa. When the harvester is working, the engine drives the working device to work to harvest crops. When the engine is started, it needs to be started by a starter. The starter can convert electrical energy into mechanical energy to drive the engine flywheel to rotate, thereby starting the engine.

[0053] During the operation of the harvester, there is a situation where the harvester stalls under load. When the harvester stalls under load and restarts, in addition to overcoming the resistance of the engine itself, it also needs to overcome the resistance of the harvester's working device, resulting in the starter needing to overcome a large load when the harvester starts, which makes the starter easy to damage, and then makes the harvester easy to damage.

[0054] In order to at least solve the problem that a harvester needs to overcome a large load when it is shut down and restarted with load, an embodiment of the present invention provides a harvester shutdown method, which can unload the harvester when it is shut down with load, thereby reducing the load that needs to be overcome when restarting.

[0055] Unloading refers to removing the load from the harvester's working device.

[0056] The harvester shutdown method according to an embodiment of the present invention will be described below in conjunction with the accompanying drawings.

[0057] like Figure 1 As shown, the harvester shutdown method of the embodiment of the present invention includes:

[0058] S100, acquiring working condition data, where the working condition data is used to characterize the working condition of the harvester;

[0059] S200, determining the working condition of the harvester according to the working condition data;

[0060] S300, according to the harvester being in a loaded working condition and in response to a flameout signal, controlling the gear to be shifted to neutral, disconnecting the main clutch, and controlling the harvester to stop and flame out.

[0061] Working condition refers to the working state of a machine under specific conditions. For a harvester, the harvester can be in a loaded working condition, such as a harvesting working condition, an original loaded working condition, etc. It is understandable that, according to actual needs, the harvester may not be in a loaded working condition, for example, the harvester may be in a non-loaded working condition, which includes an empty working condition, etc.

[0062] S100, obtaining operating data, where the operating data is used to characterize the operating state of the harvester.

[0063] As an example, the working condition data may be a drum speed, a harvester speed, etc. The drum speed and the engine speed can reflect the working condition of the harvester.

[0064] Optionally, the operating condition data is collected by sensors.

[0065] S200: Determine the working condition of the harvester according to the working condition data.

[0066] By processing the working condition data, the working condition of the harvester can be determined.

[0067] Combination Figure 1 , Figure 2 and Figure 6 As shown, in some specific embodiments, the working condition data includes the drum speed and the harvester speed, the loaded working condition includes the original loaded working condition and the harvesting working condition, and S200, the step of determining the working condition of the harvester according to the working condition data includes:

[0068] Determine whether the drum speed is 0;

[0069] When the drum speed is not 0, determine whether the harvester speed is 0;

[0070] When the harvester speed is 0, it is judged that the harvester is in the original load condition;

[0071] When the harvester speed is not 0, it is judged that the harvester is in the harvesting condition.

[0072] When the drum speed is not 0, it indicates that the harvester is in a loaded condition, and the specific working condition of the harvester can be further determined by the harvester speed.

[0073] When the drum speed is not 0 and the harvester speed is 0, it indicates that the harvester is in the original land loading condition. Therefore, it is determined that the harvester is in the original land loading condition.

[0074] When the drum speed is not 0 and the harvester speed is not 0, it indicates that the harvester is in the harvesting condition. Therefore, it is determined that the harvester is in the harvesting condition.

[0075] Therefore, the specific working condition of the harvester can be determined by the drum speed and the harvester speed.

[0076] Optionally, the vehicle speed sensor is controlled by the VCU to collect the harvester speed, and the drum speed sensor is controlled by the VCU to collect the drum speed.

[0077] VCU (Vehicle Control Unit) controls the execution of actions of relevant components of the vehicle.

[0078] S300, according to the harvester being in a loaded working condition and in response to a flameout signal, controlling the gear to be shifted to neutral, disconnecting the main clutch, and controlling the harvester to stop and flame out.

[0079] Optionally, the harvester is put into neutral gear by controlling the neutral gear relay to perform an action, thereby putting the harvester into neutral gear.

[0080] A relay is an automatic switch that uses a small current to control a large current in an automation control circuit.

[0081] In some optional embodiments, the main clutch is disconnected by controlling the main clutch relay to perform an action, thereby enabling control to disconnect the main clutch.

[0082] When the harvester is in a loaded condition and receives a flameout signal, the gear is shifted to neutral and the main clutch is disconnected to unload the harvester.

[0083] The harvester shutdown method of the embodiment of the present invention determines the working condition of the harvester through working condition data, and when the harvester is in a loaded working condition and receives a shutdown signal, controls the gear to be shifted to neutral and controls the main clutch to be disconnected to unload the harvester. As a result, the harvester can be unloaded when it is shut down with load, thereby reducing the load that needs to be overcome when restarting.

[0084] Combination Figure 3 and Figure 6 As shown, in some embodiments, S300, according to the harvester being in a loaded working condition and responding to the flameout signal, controlling the neutral gear to be engaged, disconnecting the main clutch, and controlling the harvester to stop and flame out, includes:

[0085] When the harvester is in a harvesting condition, in response to a flameout signal, determining whether the flameout signal is sent by a flameout terminal;

[0086] According to the flameout signal sent by the flameout terminal, it is judged that the flameout is caused by an incorrect operation, and the neutral gear is controlled, the main clutch is disconnected, and the engine is shut down.

[0087] The flameout terminal refers to the flameout circuit, which includes a flameout switch. When the flameout switch is turned, the flameout circuit sends a flameout signal, allowing the harvester to shut down.

[0088] When the harvester is in the harvesting condition and receives a shutdown signal from the shutdown terminal, it indicates that the harvester driver has mistakenly operated the shutdown switch, controlled the gear to be shifted to neutral, and controlled the main clutch to be disconnected to unload the harvester. Thus, the harvester can be unloaded when it is shut down with load, thereby reducing the load that needs to be overcome when restarting.

[0089] Furthermore, according to the judgment that the flameout is caused by an erroneous operation, a prompt signal is issued, and the prompt signal is used to instruct the prompt terminal to issue a prompt message of the flameout caused by an erroneous operation, so as to prompt the driver that there is an erroneous operation behavior.

[0090] In some possible implementations, the prompt terminal may be a speaker that issues a prompt message of ignition failure due to an incorrect operation by playing a voice.

[0091] Combination Figure 4 and Figure 6 As shown, in some embodiments, when the harvester speed is not 0, it is judged that the harvester is in a harvesting condition, and the harvester shutdown method further includes:

[0092] According to the harvester being in a harvesting condition, in response to not receiving a flameout signal, obtaining and determining a throttle opening;

[0093] According to the throttle opening of 100%, the engine speed of the harvester is obtained;

[0094] Determining whether a preset condition is met according to the engine speed, the preset condition being: the engine speed is less than a first threshold, or the decrease value of the engine speed in a unit time is greater than a second threshold;

[0095] The vehicle is controlled to shift into neutral gear based on the preset conditions being met.

[0096] The throttle opening refers to the degree to which the engine throttle is opened, and the throttle opening can reflect the engine intake and fuel supply. It can be understood that the throttle opening ranges from 0% to 100%. When the throttle opening is 0%, the throttle is closed, and when the throttle opening is 100%, the throttle opening reaches the maximum.

[0097] Satisfying the preset condition means that: the engine speed is less than the first threshold value. Or, the decrease value of the engine speed per unit time is greater than the second threshold value. Or, the engine speed is less than the first threshold value and the decrease value of the engine speed per unit time is greater than the second threshold value.

[0098] The engine speed is less than the first threshold, and the decrease in the engine speed per unit time is greater than the second threshold, both of which indicate that the harvester is under too much material load. There is a risk of the engine being stalled, and there is a risk of the material blocking the harvester. When the throttle opening is 100%, the driver can no longer solve the problem of the harvester being overloaded with materials by increasing the throttle opening. Therefore, controlling the gear to be in neutral can reduce the load and digest the materials, thereby reducing the load of the harvester and reducing the probability of the engine being stalled.

[0099] As some examples, the first threshold is 700 rpm (Revolutions Per Minute).

[0100] As some examples, the second threshold is 100 rpm, and the unit time is 1 second.

[0101] As a possible implementation method, the engine speed at the first time is obtained, and the engine speed at the second time is obtained, the interval between the first time and the second time is a value per unit time, and the engine speed at the first time is subtracted from the engine speed at the second time to obtain the decrease value of the engine speed per unit time. Taking the unit time as 1 second as an example, the engine speed at the first time is obtained, and the engine speed at the next second (i.e., the engine speed at the second time) is obtained. The engine speed at the first time is subtracted from the engine speed at the second time to obtain the decrease value of the engine speed per unit time.

[0102] Combination Figure 4 and Figure 6 As shown, in other embodiments, the preset condition is not met and no action is taken.

[0103] It should be noted that no action means no unloading action.

[0104] If the preset conditions are not met, the probability of the engine being stalled is relatively small, and no action is performed to avoid hindering the operation of the harvester.

[0105] like Figure 4 As shown, in some embodiments, after the preset condition is met and the harvester is controlled to be in neutral gear, the harvester stopping method further includes:

[0106] Determine whether the preset conditions are met;

[0107] When the preset conditions are met, the main clutch is disconnected.

[0108] After the control is shifted to neutral, the preset conditions are continued to be judged. If the preset conditions are still met, it means that the material load borne by the harvester is still large and the engine is facing a greater risk of being crushed and stalled. Disconnecting the main clutch can further reduce the load, thereby unloading the harvester before it stops and shuts down.

[0109] Combination Figure 4 and Figure 6 As shown, in other embodiments, no action is taken based on failure to meet a preset condition.

[0110] It should be noted that no action means no unloading action.

[0111] Since the preset conditions are not met, the neutral gear achieves a better material digestion effect, the probability of the engine being stalled is relatively small, and no action is performed to avoid hindering the operation of the harvester.

[0112] Combination Figure 5 and Figure 6 As shown, in some embodiments, when the harvester is in a harvesting condition, in response to not receiving the flameout signal, after obtaining and determining the throttle opening, the harvester shutdown method further includes:

[0113] According to the throttle opening being less than 100%, the engine speed is obtained;

[0114] Obtaining a judgment time according to the engine speed and the third threshold, the judgment time being: the continuous accumulated time during which the throttle opening is less than 100% and the engine speed is less than the third threshold;

[0115] Compare the judgment time and the fourth threshold;

[0116] According to the judgment that the time is greater than the fourth threshold, the gear is shifted to neutral and the main clutch is disconnected.

[0117] The continuous accumulated time when the throttle opening is less than 100% and the engine speed is less than the third threshold value refers to the time when the throttle opening is less than 100% and the engine speed is less than the third threshold value, and both conditions are satisfied at the same time and continuously satisfied. When the throttle opening is less than 100% and the engine speed is less than the third threshold value, one or both of the two conditions are not satisfied at a time, it is determined that the time should stop accumulating or re-accumulate.

[0118] When the engine speed is less than the third threshold, the harvester bears a greater load. When the throttle opening is less than 100%, the driver should increase the throttle opening to increase the engine speed to reduce the risk of engine stalling.

[0119] However, when the driver operates improperly and continues not to increase the throttle opening, the judgment time is greater than the fourth threshold, and the probability of the engine being stalled is relatively high. Controlling the gear to neutral and disconnecting the main clutch can further reduce the load, thereby achieving unloading of the harvester before the harvester stops and shuts down.

[0120] As some examples, the third threshold is 700 rpm.The fourth threshold may be determined by the model of the engine.

[0121] Combination Figure 5 and Figure 6 As shown, in some embodiments, based on the determination that the time is less than or equal to a fourth threshold, no action is taken.

[0122] It should be noted that no action means no unloading action.

[0123] According to the judgment time being less than or equal to the fourth threshold, the probability of the engine being stalled is relatively small, and no action is performed to avoid hindering the operation of the harvester.

[0124] In some embodiments, S200, after determining the working condition of the harvester according to the working condition data, the harvester shutdown method further includes:

[0125] According to the fact that the harvester is not in a loaded working condition, in response to the flameout signal, the harvester is controlled to stop and shut down.

[0126] Since the harvester is not in a loaded condition, the harvester can be shut down normally.

[0127] Combination Figures 2 to 6 As shown, optionally, when the drum speed is 0, the harvester is not in a loaded condition, and in response to a shutdown signal, the harvester is controlled to stop and shut down.

[0128] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0129] Based on the same inventive concept, the embodiment of the present application also provides a harvester stopping device for implementing the harvester stopping method involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more harvester stopping device embodiments provided below can refer to the limitations of the harvester stopping method above, and will not be repeated here.

[0138] When the harvester speed is 0, it is judged that the harvester is in the original load condition;

[0140] In some embodiments, the control module is further configured to:

[0142] According to the flameout signal sent by the flameout terminal, it is judged that the flameout is caused by an incorrect operation, and the neutral gear is controlled, the main clutch is disconnected, and the engine is shut down.
