[0045] Figure 1 A schematic diagram of a feeding device for a silage harvester according to an embodiment of this application is shown. (Reference) Figure 1 The feeding device 110 includes a feeding roller mechanism, which includes a first feeding roller 111 and a second feeding roller 112. The first feeding roller 111 and the second feeding roller 112 move in coordination. By adjusting the feeding gap between the first feeding roller 111 and the second feeding roller 112, the pressure applied by the feeding device to the crop at the feeding inlet can be adjusted so that the compacted crop can be chopped in the subsequent operation.

[0046] Figure 2 A schematic flowchart illustrating a control method for a forage harvester according to an embodiment of this application is shown. Figure 2 As shown, this application provides a control method for a forage harvester, which is applied to, for example... Figure 1 The silage machine shown may include the following steps.

[0047] S202, when the silage harvester is harvesting crops and the feeding device is activated, the change in the feeding gap of the feeding device at the feeding inlet is detected in real time at a preset time interval.

[0048] The feed inlet allows for pre-compression of crops. The feed gap refers to the clearance through which the crops pass. The feed gap is adjustable, thus changing the pressure applied to the crops by the feeding device. The preset time interval is a time interval set by a technician. The difference between the feed gap at the start of the preset time interval and the feed gap at the end of the preset time interval represents the change in feed gap during that time interval.

[0049] exist Figure 1 In this context, the current feeding gap is the distance between the first feeding roller 111 and the second feeding roller 112. The distance between the first feeding roller 111 and the second feeding roller 112 can be detected by detecting the position and orientation of the two feeding rollers. Preferably, one feeding roller can be set as a fixed roller, and the other as a moving roller; the distance between the first feeding roller 111 and the second feeding roller 112 can be detected by acquiring the position and orientation of the moving roller.

[0050] In the embodiments of this application, the feeding device is equipped with an angle sensor, and the feeding device includes a first feeding roller. Real-time detection of the change in the feeding gap of the feeding inlet of the feeding device during a preset time interval includes: obtaining the rotation angle of the first feeding roller during the preset time interval in real time through the angle sensor; and determining the change in the feeding gap of the feeding inlet during the preset time interval based on the rotation angle.

[0051] Specifically, refer to Figure 3 Angle sensor 310 is connected to the first feed roller 111 of the feeding device via hinge link 320. When the first feed roller 111 moves, it drives the hinge link 320 to move. The angle sensor 310 determines the position and orientation of the first feed roller 111 by measuring the rotation angle of the hinge link 320, thereby detecting the current rotation angle of the first feed roller 111 and calculating the current feeding gap at the feeding inlet based on the current rotation angle. Specifically, the radius corresponding to the rotation of the first feed roller 111 can be obtained, and the motion trajectory at the feeding inlet of the first feed roller 111 can be calculated using the arc formula to calculate the current feeding gap at the feeding inlet. 。

[0052] S204, determine the rate of change of the feed gap at the feed inlet within a preset time interval based on the change in the feed gap.

[0053] S206, if the rate of change of the feeding gap is greater than the first preset threshold, it is determined that there is a hard object in the feeding device.

[0054] The feed gap change rate refers to the ratio of the change in feed gap to the preset time interval. When the feed inlet performs pre-compacting operations on crops, the feed roller gap can be adaptively adjusted according to the harvest yield. Crops are usually uniformly compacted, so the change in feed gap is slow, and the feed gap change rate is also slow. The first preset threshold is a threshold set by technicians for the feed gap change rate. If the feed gap change rate exceeds the first preset threshold, it indicates a sudden change in the feed gap, confirming that a hard object has entered the feeding device. If the feeding device continues to operate at this time, the hard object will enter the subsequent crushing device, damaging the crushing blades. Therefore, the feeding device should be stopped to reduce the probability of hard objects entering.

[0055] S210, control the feeding device to stop operating.

[0056] In embodiments of this application, the control method further includes: acquiring the current angle of the first feed roller in real time via an angle sensor; determining the current feed gap at the feed inlet based on the current angle; and controlling the feed device to stop operation when the current feed gap is greater than a second preset threshold.

[0057] The angle sensor can directly detect the current angle of the first feed roller, that is, the angle between the current pose and the default pose of the feed roller. The second preset threshold is a threshold set by technicians for the feed gap. Based on the angle sensor, the current feed gap at the feed inlet is calculated. If the current feed gap is greater than the second preset threshold, it indicates that a hard object may be stuck in the feed roller. Furthermore, if the current feed gap is greater than the second preset threshold, the feed roller will not be able to compact the crops, affecting the working quality of the silage harvester.

[0058] In embodiments of this application, the forage harvester further includes a display device and a walking pump for controlling the movement of the forage harvester. The control method further includes: when it is determined that a hard object exists in the feeding device, sending a second signal containing the presence of a hard object in the feeding device to the display device and controlling the display device to display; controlling the feeding device to stop operation includes: controlling the feeding device to stop operation and the walking pump to stop moving.

[0059] The second signal contains information indicating the presence of a hard object in the feeding device. Upon confirming the presence of a hard object, the second signal is sent to the display device, which then shows the information on the screen, alerting the operator to the presence of a hard object in the feeding device. Simultaneously, the feeding device stops operating, the travel pump stops moving, and the header can be reversed to discharge material. Alternatively, the operator can control the header to reverse and discharge material via the handrail, searching for the stuck hard object within the area of ​​the feeding rollers in front of the header until it is found.

[0060] In embodiments of this application, the control method further includes: after the feeding device stops operating, upon receiving an operation instruction from the user and a third signal sent by the user through the display device, controlling the feeding device to start, the walking pump to move, and the header device to rotate forward to harvest crops.

[0061] The third signal refers to the signal converted from user input commands. After the feeding device stops operating, the operator can check for hard objects. After removing the hard objects, the user can input a command that the hard objects have been removed through the human-machine interface display device. The display device then sends a third signal to the processor based on this command, controlling the feeding device to start, the walking pump to move, and the header device to rotate forward to harvest crops.

[0062] In the embodiments of this application, the feeding device includes multiple hydraulic cylinders, each hydraulic cylinder is equipped with a pressure sensor, the forage harvester also includes a display device, and the control method further includes: during the real-time detection of the current feeding gap, detecting the pressure impact value of each hydraulic cylinder through each pressure sensor; determining the maximum pressure impact value among all pressure impact values; if the maximum pressure impact value is greater than or equal to a third preset threshold, determining the target position of the hard object based on the position of the hydraulic cylinder corresponding to the maximum pressure impact value; sending a first signal containing the target position to the display device, and controlling the display device to display.

[0063] Specifically, the feeding device is connected to multiple hydraulic cylinders, which can drive the first feeding roller of the feeding device to move, thereby adjusting the feeding gap at the feeding inlet. For example... Figure 4 As shown, there is a hydraulic cylinder 420 on each side of the feeding device 110. A pressure sensor is installed at the front end of the rod chamber or the end of the rodless chamber of each hydraulic cylinder. Since the resistance encountered when feeding hard objects into the feeding device is different from that encountered when feeding crops, the hard objects will cause a significant pressure impact on the hydraulic cylinders. The pressure impact caused by the hard object varies at different locations on each hydraulic cylinder. Therefore, the maximum pressure impact value can be determined by detecting the pressure impact value of each hydraulic cylinder using each pressure sensor. The third preset threshold is a threshold preset for the pressure impact value. If the maximum pressure impact value is greater than or equal to the third preset threshold, the target location of the hard object is close to the location of the hydraulic cylinder corresponding to the maximum pressure impact value. The target location of the hard object can be an area. A first signal containing the target location is sent to the display device, which displays the signal to provide feedback to the operator, facilitating the removal of hard objects from the feeding device. Furthermore, the processor can also control the feeding device to stop operating and the travel pump to stop moving based on the first signal, effectively preventing stones from being fed into the shredding drum and protecting the safe operation of the silage harvester.

[0064] After the feeding device stops operating, the operator can check for hard objects based on the target location. After the hard objects are removed, the user can input the instruction that the hard objects have been removed through the human-machine interface display device. The display device then sends a third signal to the processor based on the instruction, controlling the feeding device to start, the walking pump to move, and the header device to rotate forward to harvest crops.

[0065] The above technical solution detects the change in the feeding gap of the feeding device at a preset time interval in real time when the forage harvester is harvesting crops and the feeding device is activated. Based on the change in the feeding gap, the rate of change of the feeding gap at the preset time interval is determined. If the rate of change of the feeding gap exceeds a first preset threshold, a hard object is detected within the feeding device, and the feeding device is stopped. This effectively detects hard objects entering the feeding device, ensuring safe operation of the forage harvester.

[0066] An embodiment of this application provides a silage harvester, comprising:

[0067] Feeding device, used to feed harvested crops;

[0068] According to the control device for the forage machine described above.

[0069] In the embodiments of this application, such as Figure 5 As shown, the feeding device 510 includes multiple hydraulic cylinders 511, and the forage harvester also includes: an angle sensor 520, installed on the feeding device 510, for acquiring the rotation angle of the feeding device 510; multiple pressure sensors 512, each pressure sensor installed on each hydraulic cylinder, each pressure sensor for detecting the pressure impact value received by each hydraulic cylinder; a header device 530 for harvesting crops; a travel pump 540 for controlling the movement of the forage harvester; a display device 550 for displaying received signals and sending signals input by the user through the display device; and a control device 560 for the forage harvester, configured to execute the above-described control method for the forage harvester.

[0070] refer to Figure 1 , Figure 3 as well as Figure 4 In a specific embodiment, such as Figure 1 As shown, the feeding device 110 includes a feeding roller mechanism, which includes a first feeding roller 111 and a second feeding roller 112. The first feeding roller 111 and the second feeding roller 112 move in coordination. By adjusting the feeding gap between the first feeding roller 111 and the second feeding roller 112, the compaction pressure of the crop at the feeding inlet can be adjusted, so that the compacted crop can be chopped subsequently. The feeding roller mechanism is connected to a chopping roller 120, which is connected to a grain crushing roller. The chopping roller 120 can chop the crop, and the grain crushing roller 130 can crush the crop grains. The husks of the grains are discharged by a fan 140 connected to the grain crushing roller 130. Furthermore, the silage machine also includes a tail boom 150 to discharge the chopped crop. Figure 3As shown, the angle sensor 310 is connected to the first feed roller 111 of the feeding device via a hinged link 320. When the first feed roller moves, it drives the hinged link to move. The angle sensor measures the rotation angle of the link to determine the position of the first feed roller, thus detecting the current rotation angle of the first feed roller 111. Figure 4 As shown, the feeding device 110 has a hydraulic cylinder 420 on each side, and a pressure sensor is installed at the front end of the rod chamber or the end of the rodless chamber of each hydraulic cylinder. The cylinder barrels are fixed to the frame of the feeding device 110 by a fixing seat. The feeding device 110 also includes a spring assembly 430, one end of which is connected to the frame of the feeding device 110, and the other end is connected to the first feeding roller 111, which can effectively help the feeding roller pre-compact the crops.

[0071] In one embodiment, the current angle of the first feed roller can be acquired in real time using an angle sensor, and the current feeding gap at the feed inlet can be determined based on the current angle. It can be understood that the spring assembly is connected to the feed roller mechanism and moves along with the feed roller mechanism. Therefore, the spring force on the spring assembly can be calculated based on the spring constant and the current feeding gap. A preset spring force threshold can then be set by the technician. This preset spring force value can be set based on the technician's experience with the feed roller mechanism when it enters hard objects. If the spring force value exceeds the preset spring force threshold, the feeding device will stop operating.

[0072] This application provides a control device for a forage harvester, which may include:

[0073] The memory is configured to store instructions; and

[0074] The processor is configured to retrieve instructions from memory and, when executing the instructions, to implement the aforementioned control method for the forage machine.

[0075] Specifically, in this embodiment of the application, the processor can be configured as follows:

[0076] While the silage harvester is harvesting crops and the feeding device is activated, the change in the feeding gap of the feeding device at the feeding inlet during a preset time interval is monitored in real time.

[0077] The rate of change of the feed gap at the feed inlet within a preset time interval is determined based on the change in the feed gap.

[0078] If the rate of change of the feeding gap is greater than the first preset threshold, it is determined that there is a hard object inside the feeding device;

[0079] Stop the feeding device from operating.

[0080] In this embodiment of the application, the processor can also be configured to:

[0081] The feeding device is equipped with an angle sensor and includes a first feeding roller. Real-time detection of the change in the feeding gap of the feeding inlet of the feeding device during a preset time interval includes: obtaining the rotation angle of the first feeding roller during the preset time interval in real time through the angle sensor; and determining the change in the feeding gap of the feeding inlet during the preset time interval based on the rotation angle.

[0082] In this embodiment of the application, the processor can also be configured to:

[0083] The current angle of the first feed roller is obtained in real time by an angle sensor; the current feed gap at the feed inlet is determined based on the current angle; if the current feed gap is greater than a second preset threshold, the feeding device is controlled to stop operation.

[0084] In this embodiment, the feeding device includes multiple hydraulic cylinders, each equipped with a pressure sensor. The forage harvester also includes a display device, and the processor can be configured to:

[0085] During the real-time detection of the current feeding gap, the pressure impact value of each hydraulic cylinder is detected by each pressure sensor; the maximum pressure impact value among all pressure impact values ​​is determined; if the maximum pressure impact value is greater than or equal to a third preset threshold, the target position of the hard object is determined according to the position of the hydraulic cylinder corresponding to the maximum pressure impact value; a first signal containing the target position is sent to the display device, and the display device is controlled to display the content of the first signal.

[0086] In embodiments of this application, the forage harvester further includes a display device and a walking pump for controlling the movement of the forage harvester, and the processor may also be configured to:

[0087] If a hard object is detected in the feeding device, a second signal indicating the presence of a hard object is sent to the display device, and the display device is controlled to display the content of the second signal; controlling the feeding device to stop operation includes controlling the feeding device to stop operation and the walking pump to stop moving.

[0088] In this embodiment of the application, the processor can also be configured to:

[0089] After the feeding device stops operating, upon receiving the user's operation command and a third signal sent by the user through the display device, the system controls the feeding device to start, the walking pump to move, and the header device to rotate forward to harvest crops.

[0090] Through the above technical solution, when the silage harvester is harvesting crops and the feeding device is activated, an angle sensor detects the current rotation angle of the first feeding roller. This allows for real-time monitoring of the feeding gap change at the feeding inlet within a preset time interval, calculating the feeding gap change rate. If the feeding gap change rate exceeds a first preset threshold, a hard object is detected within the feeding device, thus stopping the operation. This effectively detects hard objects entering the feeding device, ensuring safe operation of the silage harvester. Simultaneously, pressure sensors can be installed on the hydraulic cylinders of the feeding device. Based on the pressure impact values ​​detected by different pressure sensors, the location of the hard object within the feeding device is determined and displayed on the display device. This solution allows operators to quickly locate and remove hard objects, improving the efficiency of the silage harvester. The human-machine interface display device receives equipment alerts from the silage harvester and, after removing the hard object, receives user operation information to restart the silage harvester, making its operation safer and more reliable.

[0091] This application also provides a machine-readable storage medium storing instructions that cause the machine to perform the above-described control method for a forage harvester.

When the processor A01 executes the computer program B02, it implements a control method for the silage harvester.
