Bucket movement control device for automatically shaking off foreign substances and method therefor

Abstract

An apparatus for controlling bucket movement for automatically shaking off foreign substances is disclosed, which includes a bucket movement control unit controlling the bucket movement by determining whether to output an automatic control signal for automatically driving the bucket forward and backward at a predetermined speed even if an input value of a joystick is not changed or to output a manual control signal for driving the bucket according to an operation value of the joystick, in accordance with a selection/non-selection of an automatic mode by an automatic mode selection switch, an operation value detected by an operation value detection means, and an operation angle detected by an operation angle detection means, and outputting a corresponding signal to a bucket driving unit. The movement of the bucket can be automatically controlled so as to control the foreign substances contained in the bucket and to sprinkle earth and sand without any separate operation of an operator.

1 . An apparatus for controlling bucket movement for automatically shaking off foreign substances, comprising:
 an automatic mode selection switch;   an operation value detection means for detecting an operation value generated by a stroke of a joystick;   an operation angle detection means for detecting an operation angle of the joystick; and   a bucket movement control unit controlling the bucket movement by determining whether to output an automatic control signal for automatically driving the bucket forward and backward at a predetermined speed even if an input value of the joystick is not changed or to output a manual control signal for driving the bucket according to the operation value of the joystick, in accordance with a selection/non-selection of an automatic mode by the automatic mode selection switch, the operation value detected by the operation value detection means, and the operation angle detected by the operation angle detection means, and outputting a corresponding signal to a bucket driving unit.   
     
     
         2 . The apparatus for controlling bucket movement according to  claim 1 , wherein the bucket movement control unit outputs the automatic control signal to the bucket driving unit in an automatic control state where the automatic mode is selected by the automatic mode selection switch, the operation value of the joystick is equal to or smaller than a set value, and a command direction obtained from the operation angle of the joystick coincides with a predefined direction, and
 outputs the corresponding manual control signal to the bucket driving unit in a manual control state where the automatic mode is not selected by the automatic mode selection switch, the operation value of the joystick is larger than the set value, or the command direction obtained from the operation angle of the joystick does not coincide with a predefined direction.   
     
     
         3 . The apparatus for controlling bucket movement according to  claim 2 , wherein in the automatic control state, the bucket movement control unit outputs a first automatic control signal for shaking the bucket slowly to the bucket driving unit if the operation value of the joystick belongs to a first range that is relatively small, and outputs a second automatic control signal for shaking the bucket quickly to the bucket driving unit if the operation value of the joystick belongs to a second range that is relatively large. 
     
     
         4 . A method for controlling bucket movement for automatically shaking off foreign substances, comprising:
 selecting an automatic mode;   detecting an operation value generated by a stroke of a joystick;   detecting an operation angle of the joystick; and   controlling the bucket movement by determining whether to output an automatic control signal for automatically driving the bucket forward and backward at a predetermined speed even if an input value of the joystick is not changed or to output a manual control signal for driving the bucket according to the operation value of the joystick, in accordance with a selection/non-selection of an automatic mode, the operation value of the joystick, and the operation angle of the joystick, and outputting a corresponding signal to a bucket driving unit.   
     
     
         5 . The method for controlling bucket movement according to  claim 4 , wherein the bucket movement control step outputs the automatic control signal to the bucket driving unit in an automatic control state where the automatic mode is selected, the operation value of the joystick is equal to or smaller than a set value, and a command direction obtained from the operation angle of the joystick coincides with a predefined direction, and
 outputs the corresponding manual control signal to the bucket driving unit in a manual control state where the automatic mode is not selected, the operation value of the joystick is larger than the set value, or the command direction obtained from the operation angle of the joystick does not coincide with a predefined direction.   
     
     
         6 . The method for controlling bucket movement according to  claim 5 , wherein in the automatic control state, the bucket movement control step outputs a first automatic control signal for shaking the bucket slowly to the bucket driving unit if the operation value of the joystick belongs to a first range that is relatively small, and outputs a second automatic control signal for shaking the bucket quickly to the bucket driving unit if the operation value of the joystick belongs to a second range that is relatively large.
