Abstract

PURPOSE:To prevent an accident from occurring by controlling the execution of spin turn by the judgment based on the combination of the inclined angle with the vehicle speed of a machine frame to perform safe spin turn at all times. CONSTITUTION:Inclination sensors 61 and 62 to detect the inclined angle of a machine frame are provided and connected to the input of a control circuit 46, and a spin turn execution allowable value set in combination of inclined angle with vehicle speed is input into the control circuit 46 beforehand. When a calculation value detected by the inclination sensors 61 and 62 and a vehicle speed sensor 48 is the spin turn execution allowable value or less, an instruction is given from the control circuit 46 by the ON operation of a spin turn switch 59 so as to operate a spin turn operating member.

SUMMARY OF THE INVENTION In order to provide an object of the present invention to achieve the object described above, the present invention provides a spinner switch for controlling the spinner switch when the spin turn switch is turned on through a control circuit.
In a mobile agricultural machine equipped with a spin turn operation member for turning on and off, a spin sensor that detects the tilt angle of the machine body is provided and connected to the control circuit, and the spin angle is set by combining both the tilt angle of the machine body and the vehicle speed. When the calculated value detected by the tilt sensor and the vehicle speed sensor is less than or equal to the spin turn execution allowable value, the spin turn switch is turned on to cause the control circuit to input the start execution value to the control circuit. It is characterized in that a command is issued to operate the spin turn operation member.

Therefore, the spin turn execution permissible value pre-input to the control circuit becomes slow when the tilt angle of the body is large, and becomes slightly fast when the tilt angle is small. Then, the inclination angle and the vehicle speed are composed in a combination that is inversely proportional to each other. When the spin turn switch is turned on to spin-turn the vehicle while the vehicle is traveling with the inclination of the vehicle being small, the inclination sensor -And the vehicle speed sensor-calculated value is less than the spin turn execution permissible value, a command is issued from the control circuit to the spin turn operating member to perform spin turn, and
In that case, if the vehicle speed is unexpectedly high and is higher than the spin turn execution permissible value, the spin turn will not be performed even if the spin turn switch is turned on.

Further, when the vehicle body is tilted at a low speed such as when loading or unloading it on a truck or the like, the calculated value detected by the tilt sensor and the vehicle speed sensor is out of the spin turn execution allowable value. Even if the spin turn switch is operated, the control circuit does not give a command to the spin turn actuating member and the spin turn does not occur, so that the spin turn can be safely loaded and unloaded.

Further, the control circuit (46) is inputted with the spin turn execution allowable value (X) which is set by combining both the inclination angle (α) of the machine body and the vehicle speed (V). That is, the spin turn execution permissible value (X) is the safety limit tilt angle of the aircraft when the vehicle speed (V) is used as the reference, or the safety limit vehicle speed when the aircraft tilt angle (α) is used as the reference. It means that, as shown in "Fig. 9",
(A)-(b) is a line composed of a combination of the inclination angle (α) and the vehicle speed (V) and is equal to or less than the spin turn execution allowable value (X). Therefore, the spinner is executable.
