Description

Technical Field

[0001] This utility model relates to a lifting and control system for a sugarcane machine's feed box and fan. Background Technology

[0002] Sugarcane harvesters are crucial agricultural machinery for efficient sugarcane harvesting. Existing segmented sugarcane harvesters primarily collect sugarcane segments through a hopper during operation and unload them once the hopper is full to ensure continuous operation. Currently, the commonly used unloading control method involves detection and control via proximity switches. When the hopper reaches a preset full load state, the proximity switch triggers a signal, causing the hopper to unload. However, this control method has certain limitations.

[0003] First, the proximity switch's triggering method is relatively simple, relying solely on mechanical activation when the material box reaches a certain position. This results in low control flexibility and difficulty in adapting to different operating environments. Second, during unloading, the movement trajectories of the material box and the blower may interfere, easily causing equipment collisions or malfunctions, thus affecting the smooth unloading process. Furthermore, traditional control methods rarely consider dynamic adjustments and cannot optimize the coordinated movement of the material box and blower according to different operating conditions, potentially leading to reduced operating efficiency or even the risk of equipment damage.

[0004] Therefore, there is still room for improvement in the existing technology for unloading control of sugarcane harvesters. A more intelligent control system is needed to avoid interference between the movement of the hopper and the blower, and to improve the automation and reliability of the unloading process. Utility Model Content:

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a lifting and control system for a sugarcane machine feed box and a blower.

[0006] A lifting and lowering control system for a sugarcane machine's feed hopper and fan includes a control module, a feed hopper, a fan, a first actuator, and a second actuator. The first actuator controls the movement of the feed hopper, and the second actuator controls the movement of the fan. Normally, the fan is positioned along the movement trajectory of the feed hopper. The control module contains a motion control program, which is called by a processor to execute the following steps:

[0007] Determine whether the blower is on the material box's movement trajectory. If the blower is on the material box's movement trajectory, the first actuator is in standby mode; otherwise, the first actuator controls the material box to move to the working position or reset.

[0008] Determine if the material box is in the normal position. If the material box is not in the normal position, the second actuator is in standby mode. Otherwise, the second actuator controls the fan to move to the working position or reset.

[0009] Furthermore, the aforementioned hopper and fan rotate.

[0010] Furthermore, the first and second actuators are linear telescopic hydraulic cylinders.

[0011] Furthermore, the control module includes a controller, a first proximity switch, a second proximity switch, and a third proximity switch. The first proximity switch is used to sense that the fan is in the normal position, the second proximity switch is used to sense that the fan is in the working position, and the third proximity switch is used to sense that the material box is in the normal position. The controller is used to receive signals from the proximity switches, and the controller stores a program.

[0012] Furthermore, it also includes a proximity switch activation determination procedure, which activates the proximity switch based on a signal received by the controller from the control panel.

[0013] Furthermore, the control module also includes an instrument used to display the status of the hopper and the blower.

[0014] Furthermore, it also includes an alarm program. When the proximity switch is activated, if the controller does not receive a signal that the fan is in the normal position but receives a movement signal from the entire unit, the alarm program will issue an alarm signal.

[0015] Beneficial effects: Compared with existing technologies, this system effectively avoids movement conflicts between the material hopper and the blower through specific programming, reducing the risk of equipment damage and improving the operating efficiency of the sugarcane machine. Automated control reduces manual intervention, improving operational safety and equipment lifespan. Furthermore, this control system can adapt to different operational needs, ensuring coordinated operation of the blower and material hopper and optimizing equipment performance.

[0019] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0020] A sugarcane machine material box and blower lifting control system includes a control module, a material box 5, a blower 4, a first actuator, and a second actuator. The first actuator controls the movement of the material box 5, and the second actuator controls the movement of the blower 4. Under normal conditions, the blower 4 is located on the movement trajectory of the material box 5. The control module contains a motion control program, which is called by a processor to execute the following steps: determining whether the blower 4 is located on the movement trajectory of the material box 5; if the blower 4 is located on the movement trajectory of the material box 5, the first actuator is in a standby state; otherwise, the first actuator controls the material box 5 to move to the working position or reset; determining whether the material box 5 is in the normal position; if the material box 5 is not in the normal position, the second actuator is in a standby state; otherwise, the second actuator controls the blower 4 to move to the working position or reset.

[0021] Working principle:

[0022] The core of this control system is to coordinate the movement of the material box 5 and the blower 4 through a control module, preventing interference between them. The blower 4 is initially positioned on the trajectory of the material box 5. Therefore, before the material box 5 moves, the system first checks the position of the blower 4. If the blower 4 is still on the trajectory, the movement of the material box 5 is stopped; otherwise, the material box 5 is allowed to move to the working position or reset. Similarly, during the movement of the material box 5, the system checks whether it is in the normal position. If not, the movement of the blower 4 is paused until the material box 5 reaches the required position, at which point the blower 4 will be controlled to move to the target position. This logic ensures the safety and reliability of the system operation.

[0023] In another possible implementation, the hopper 5 and the fan 4 rotate. That is, the first and second actuators drive the hopper 5 and the fan 4 to rotate along the axis of rotation, rather than in a linear motion.

[0024] In another possible implementation, the first and second actuators are linear telescopic hydraulic cylinders. That is, the movement of the material box 5 and the blower 4 is achieved by the extension and retraction of the hydraulic cylinders, ensuring the stability and accuracy of the system operation.

[0025] In another possible implementation, the control module includes a controller, a first proximity switch 1, a second proximity switch 2, and a third proximity switch 3. The first proximity switch 1 is used to sense that the fan 4 is in the normal position, the second proximity switch 2 is used to sense that the fan 4 is in the working position, and the third proximity switch 3 is used to sense that the material box 5 is in the normal position. The controller is used to receive signals from the proximity switches and stores corresponding programs.

[0026] In another possible implementation, a proximity switch activation determination procedure is also included, which activates the proximity switch based on the control panel signal received by the controller, thereby more intelligently managing the movement state of the hopper 5 and the fan 4.

[0027] In another possible implementation, the control module also includes an instrument for displaying the status information of the material bin 5 and the blower 4 in real time, so that operators can monitor the operation of the equipment.

[0028] In another possible implementation, an alarm program is also included. When the proximity switch is activated, if the controller does not receive a signal that the fan 4 is in the normal position, but receives a movement signal from the entire machine, the alarm program will issue an alarm signal to remind the operator that there may be an abnormality in the system, thereby improving the safety of the equipment.

[0029] Specific usage process: When unloading is required, the motion control program is called, and the proximity switch judgment program controls the proximity switch to start. At this time, both the blower 4 and the material box 5 are in the normal position. First, the blower 4 moves to the working position. After the second proximity switch 2 senses it, the material box 5 moves to the working position to unload the material and then resets. After the third proximity switch 3 senses it, the blower 4 resets.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
