Abstract

The present disclosure relates to a construction machine based on a high dump bucket. The construction machine based on a high dump bucket includes a boom that rotatably connected to a main body of the construction machine based on a first rotating shaft; a bucket support rotatably connected to the boom based on a second rotating shaft and configured to support a high dump bucket; the high dump bucket rotatably connected to the bucket support based on a third rotating shaft; a bucket angle sensor configured to detect a rotation angle of the high dump bucket; and a control unit configured to determine a posture of the construction machine based on bucket angle data obtained from the bucket angle sensor.

 a boom that rotatably connected to a main body of the construction machine based on a first rotating shaft;   a bucket support rotatably connected to the boom based on a second rotating shaft and configured to support a high dump bucket;   the high dump bucket rotatably connected to the bucket support based on a third rotating shaft;   a bucket angle sensor configured to detect a rotation angle of the high dump bucket; and   a control unit configured to determine a posture of the construction machine based on bucket angle data obtained from the bucket angle sensor.   
     
     
         2 . The high dump bucket-based construction machine of  claim 1 , wherein when the control unit receives a first user input for performing a high dump operation, the control unit changes a rotation angle of the high dump bucket to a predetermined first angle through the second rotating shaft based on the bucket angle data. 
     
     
         3 . The high dump bucket-based construction machine of  claim 2 , wherein when a rotation angle of the boom is equal to or greater than a predetermined standard, in a case where the control unit receives a second user input for setting an angle of the high dump bucket, the control unit sets an angle corresponding to the second user input to the predetermined first angle. 
     
     
         4 . The high dump bucket-based construction machine of  claim 2 , wherein the predetermined first angle is tilted further by a predetermined angle toward a front side in a full crowd state of the high dump bucket. 
     
     
         5 . The high dump bucket-based construction machine of  claim 2 , wherein the control unit receives the first user input based on whether a bucket kick-out function is activated and a joystick associated with the construction machine is operated to the first end. 
     
     
         6 . The high dump bucket-based construction machine of  claim 1 , further comprising a boom angle sensor configured to detect a rotation angle of the boom,
 wherein when the control unit receives a third user input to perform a high dump operation, the control unit changes the rotation angle of the boom to a predetermined second angle through the first rotating shaft based on boom angle data obtained from the boom angle sensor, and changes the rotation angle of the high dump bucket to a predetermined first angle through the second rotating shaft based on the bucket angle data.   
     
     
         7 . The high dump bucket-based construction machine of claim  8 , wherein the control unit receives the third user input based on whether the joystick is operated to the second end in a state in which a kick-down button of a joystick associated with the construction machine is pressed. 
     
     
         8 . The high dump bucket-based construction machine of  claim 7 , wherein when the joystick is operated while at least one of the rotation angle of the boom and the rotation angle of the high dump bucket is changed, the control unit stops changing the angle. 
     
     
         9 . The high dump bucket-based construction machine of  claim 1 , wherein when the control unit receives a fourth user input for performing a high dump operation, the control unit dumping-drives the high dump bucket through the third rotating shaft. 
     
     
         10 . The high dump bucket-based construction machine of  claim 9 , wherein the control unit receives the fourth user input based on whether a kick-down button of the joystick is pressed. 
     
     
         11 . A high dump bucket-based construction machine comprising:
 a boom that rotatably connected to a main body of the construction machine based on a first rotating shaft;   a bucket support rotatably connected to the boom based on a second rotating shaft and configured to support a high dump bucket;   the high dump bucket rotatably connected to the bucket support based on a third rotating shaft;   a bucket angle sensor configured to detect a rotation angle of the high dump bucket;   a boom angle sensor configured to detect a rotation angle of the boom; and   a control unit configured to change the high dump bucket to a predetermined first angle when the boom is change to a predetermined second angle to perform a high dump operation.   
     
     
         12 . A posture control method of a high dump bucket-based construction machine performed by at least one processor, the posture control method comprising:
 determining whether a kick-out function associated with the construction machine is activated;   determining whether a joystick is operated to a second end in a state where a kick-down button of a joystick associated with the construction machine is pressed; and   controlling the high dump bucket of the construction machine to a predetermined first angle and controlling a boom of the construction machine to a predetermined second angle when it is determined whether the kick-out function is activated and whether the joystick is operated.   
     
     
         13 . The posture control method of  claim 12 , further comprising:
 determining whether the kick-down button of the joystick is input when the angles of the boom and high dump bucket of the construction machine are changed; and   performing a dumping operation of the high dump bucket when it is determined that the kick-down button is input.   
     
     
         14 . The posture control method of  claim 12 , further comprising stopping changing of the angle when the joystick is operated while at least one of a rotation angle of the boom and a rotation angle of the high dump bucket is changed.
