Description

Technical Field

[0001] The utility model relates to a remote control system for unloading a barrel of a harvester. Background Art

[0002] The grain unloading drums currently widely used in agricultural harvesting operations are controlled by fixed operating panels or spring-pull handles inside the cab. These two operating panels have great limitations. It is not convenient to view the rotation angle of the anti-aircraft gun, the progress of grain unloading, and the real-time situation of the barrel falling back after unloading in the cab.

[0003] Even if the spring cable handle can be adjusted under the vehicle, the length of the spring cable is limited, which makes it difficult to observe properly. This results in grain being scattered due to the failure to adjust the grain barrel to the designated unloading position when unloading grain, and damage to the vehicle body or surrounding environment due to inaccurate and untimely angle adjustment when the anti-aircraft gun falls back. This does not provide users with better vehicle use assistance, but also increases labor costs and wastes time. Utility Model Content

[0004] The purpose of the utility model is to solve the above deficiencies in the prior art and provide a remote control system for unloading a harvester drum.

[0005] A remote control system for a harvester unloading drum comprises a motor, an unloading drum and a remote control system. The motor is provided with a controller. The remote control system comprises a wireless remote controller and a wireless receiver. The wireless receiver is connected to the controller via CAN protocol transmission. The wireless remote controller is used to send control signals. The wireless receiver is used to receive control signals. The wireless receiver and the wireless remote controller are connected via radio wave signals.

[0006] The controller transmits the signal to the solenoid valve that controls the lifting of the grain unloading barrel and controls the motor to rotate left and right, thereby driving the anti-aircraft gun grain unloading barrel to rotate left and right.

[0007] Preferably, the wireless remote control includes a plurality of control buttons, and the control buttons include an out button, an in button, an up button, a down button, a left button, and a right button.

[0008] Preferably, the wireless receiver comprises a radio receiving module, a microcontroller or a processor, and a corresponding output interface.

[0009] Preferably, the controller is connected to the control handle via CAN protocol transmission, the control handle is installed on the harvester body, the control handle is used to send a control signal to the controller, the control handle includes a plurality of control buttons, the control buttons include a transfer button, a transfer button, an up button, a down button, a left button, a right button, a one-button right transfer button, a one-button backward transfer button, a one-button return button, and a calibration button.

[0010] Preferably, the motor is a brushless motor.

[0011] Beneficial effects: Compared with the prior art, the utility model retains the original structure of the spring wire handle to control the grain unloading barrel adjustment, and adds a remote controller and a remote signal receiver for the grain unloading barrel to the original structure. A harvester equipped with a remote grain unloading function can use wireless remote control to unload grain even if the spring wire handle unloading method equipped on the original vehicle fails. This greatly reduces the parking and maintenance costs during rush harvesting, giving users a better vehicle experience.

[0012] When we are operating the grain unloading barrel, if the driver cannot observe the track of the grain unloading barrel better due to the limitations of the cab, then the personnel on the grain transport vehicle side can remotely operate the grain unloading barrel with a wireless remote control. Eliminating the blind spots and area restrictions of the driver's control of the grain unloading handle inside the cab makes grain unloading operation safer, more reliable, more convenient and faster, saving unnecessary time waste and giving users a better vehicle experience.

[0013] The system has a simple structure framework, and adds detailed control over the steering of the grain unloading drum during remote control. It saves time, is easy to use and maintain, and is not easy to damage, laying the foundation for all-round intelligent remote control of the harvester. BRIEF DESCRIPTION OF THE DRAWINGS
