The notch 7.4 of the hook groove 7.2 is inclined 60 degrees upwards and anticlockwise.

The power source 4 is a motor.

The specific workflow is as follows:

the initial state is the grab bucket open state:

the starter motor drives the clockwise rolling of haulage rope, grab bucket 1 promotes upwards, 3 couples the second of 1.1.1.1 of portion of colluding of palate 1.1 at grab bucket 1 this moment colludes in nest 1.1.1b, motor 4 continuously operates, locking lever 6 of chin 1.2 upwards shifts along the orbit slope of guide rail 5, promote 7 auricles of hasp, when breaking away from 7 auricles of hasp colluding groove 7.2's notch highest end, hasp 7 is because of under the action of gravity, the perpendicular decurrent position of backswing, hasp 7 is crossed at the both ends of the 6 body of rod of locking lever this moment, fall on the rear of hasp 7.

The motor is controlled to stop running and start to rotate anticlockwise, the traction rope 2 starts to fall back, the grab bucket 1 starts to slide downwards along the guide rails 5, the lock rod 6 pushes the lock catch 7 to turn over reversely, when the lock rod 6 slides to the position below the lock catch 7 and is not in contact with the lock catch 7, the lock catch 7 swings backwards and is positive, and the grab bucket 1 continues to fall along the guide rails 5 on the two sides.

When the opened grab bucket 1 falls to the bottom end of the guide rail, the lower jaw 1.2 of the grab bucket 1 cannot descend any more, the polyester belt 4 continues to be lowered under the condition that the motor 4 continues to rotate, and the upper jaw 1.1 is closed anticlockwise around a pin shaft at the hinged part of the upper jaw and the lower jaw under the action of gravity;

when the upper jaw 1.1 of the grab bucket is closed, the traction rope 2 is continuously lowered, the hook 3 can continuously descend for a certain distance due to the accommodating cavity 3.2, and the hook 3 swings and moves to the first hooking part 1.2.1 of the lower jaw 1.2 under the action of gravity.

The control motor 4 starts to rotate reversely, the traction rope 2 starts to be wound, the grab bucket 1 starts to ascend along the guide rails 5 on the two sides again, and the hook 3 is hung in the first hook nest 1.2.1b of the first hook part 1.2.1 at the moment.

When the grab bucket 1 rises to the position of the lock catch 7, the lock rod 6 of the lower jaw 1.2 pushes the lock catch 7 away in the backward direction, the lock rod 6 falls into the hook groove 7.2 after passing through the front end of the hook groove of the lock catch 7, the motor 4 is controlled to stop and run reversely, the grab bucket 1 descends for a short distance, the grab bucket 1 is hung on the lock catch 7, the motor 4 continues to run at the moment, the traction rope 2 is loosened, the hook 3 swings back to the lower part of the second hook part 1.1.1 of the upper jaw 1.1 under the action of gravity, the reason that the upper half section 7.2 of the guide rail 5 is inclined or bent is that the hook 3 swings back to a vertical angle, the motor 4 is controlled to start to rotate reversely, the polyester belt 4 starts to continue to rotate, the grab bucket 1 is gradually opened due to the fact that the second hook pit 1.1.1b of the upper jaw 1.1 is hooked by the hook 3, the motor 4 stops and returns to the.

The described embodiments are only some, but not all embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
