When the bucket 8 designed by the invention carries stones, if the position of the stone is lower than the ground height of the excavator track 3, the hydraulic telescopic rod 20 needs to be controlled, so that the hydraulic telescopic rod 20 stretches, the hydraulic telescopic rod 20 stretches and swings through the two swing rods 19, the two swing plates 16 swing to drive the transmission plate 10 to transversely move downwards, the transmission plate 10 drives the connecting plate 11 to swing downwards through the transmission rod 35, the connecting plate 11 drives the driving plate 13 to swing downwards, and the driving plate 13 swings downwards to drive the bottom supporting plate 14 and the two swing plates 16 arranged on the driving plate 13 to swing downwards, so that the front ends of the two swing plates 16 move to be flush with the bottom of the stone as much as possible.

In the invention, when the excavator rotates to move the excavator bucket 8 to carry lateral stone blocks, in order to ensure that the rotation of the bottom support plate 14 cannot be influenced by the stone blocks on the ground in the process that the bottom support plate 14 rotates along with the chassis and the excavator bucket 8, when no stone block is placed on the swinging plate 16, a gap is formed between the bottom support plate 14 and the ground; after the stone is pushed to the level and is put on two pendulum plates 16, the stone can press two pendulum plates 16, bottom sprag board 14 and the relative connecting plate 11 of drive plate 13 and move down for bottom sprag board 14 plays supporting role to the stone with ground contact, and bottom sprag board 14, two pendulum plates 16 and drive plate 13 all can upwards reset under the effect of first spring 34 after the stone is taken off, can not influence the rotation of digging the machine.

In the excavator, the base 4 drives the transmission plate 10 to rotate through the mounting plate 9 and the swing rod 19 in the rotation process of the excavator, and because the connection plate 11, the drive plate 13, the bottom support plate 14 and the swing plate 16 have certain weight, when the transmission plate 10 rotates, the connection plate 11 connected with the transmission plate 10 through the transmission rod 35 generates a hysteresis phenomenon, but after the rotation speed is adapted, the transmission plate 10 drives the connection plate 11, the drive plate 13, the bottom support plate 14 and the swing plate 16 to rotate at the same speed through the transmission rod 35.

In the rotation process of the excavator, if the bottom support plate 14 is contacted with a stone on the ground, the stone can generate rotation resistance on the bottom support plate 14, the bottom support plate 14 is transmitted to the connecting plate 11 through the drive plate 13, so that the connecting plate 11 generates a hysteresis phenomenon relative to the drive plate 10 under the action of the two guide chutes 40 and the drive rod 35, in this state, the connecting plate 11 can move upwards relative to the drive plate 10 under the action of the guide chutes 40 and the drive rod 35 to pass through the stone, and the connecting plate 11 and the drive plate 10 can reset under the action of the gravity of the connecting plate 11 and the third spring 36 after passing through the stone.

The third spring 36 plays a role in restoring the connecting plate 11 and the driving plate 10, and can restore itself by the gravity of the connecting plate 11 after the hysteresis phenomenon of the driving plate 10 and the connecting plate 11 occurs.

The specific working process is as follows: when the excavator bucket 8 designed by the invention is used for carrying a stone block, firstly, the excavator bucket 8 of the excavator is controlled to push the stone block, so that the stone block is obliquely placed on the upper sides of the two swing plates 16, then, the excavator bucket 8 is controlled to push the stone block to obliquely move upwards along the two swing plates 16, in the moving process, along with the backward movement of the gravity center of the stone block on the two swing plates 16, the originally oblique two swing plates 16 are pressed by the stone block to swing towards the horizontal state, in the process that the two swing plates 16 swing from the oblique state to the horizontal state, the two swing plates 16 drive the locking rods 17 to swing, when the two swing plates 16 swing to the horizontal state, the locking rods 17 installed on the two swing plates firstly contact with the locking plates 21 installed on the driving plates 13 and press the locking plates 21, so that the locking plates 21 swing downwards, after the locking rods 17 completely pass over the locking plates 21, the locking plates 21 swing upwards under the action of the second volute springs 28 to reset to play a limiting role on the locking rods 17, one end of the other end of the two swing plates 16 is just right away from the driving plates 13, namely, and the supporting ends of the two swing plates 16 are placed on the driving plates 13, and play a role in the supporting function of the stone block when the locking rods 17 is in the horizontal state.

Under the pushing of the excavator bucket 8 and the swinging action of the swing plates 16, after the stone swings to a horizontal state, the excavator bucket 8 is controlled to enable the excavator bucket 8 to wrap the stone from the lower sides of the two swing plates 16, namely the lower sides of the stone, in the process, the excavator bucket 8 can firstly contact with the trigger plate 18 arranged on the front side of the drive plate 13 and push the trigger plate 18 from bottom to top, so that the trigger plate 18 swings, the second pull rope 31 is pulled by the swinging of the trigger plate 18, the two first pull ropes 30 are pulled by the second pull rope 31, the two mounting sliding blocks 22 are pulled by the two first pull ropes 30 to move towards the middle, the two mounting sliding blocks 22 move to drive the mounting support lugs 27 on the mounting support lugs to move, the mounting support lugs 27 move to drive the two locking plates 21 to move to be separated from the two locking rods 17, the locking plates 21 are unlocked to the two swing plates 16 and the drive plate 13, the excavator bucket 8 is completely inserted into the lower side of the stone at the moment, and even if the two swing plates 16 are reset forward under the pressure of the stone, the excavator bucket 8 can not be influenced by the stone to wrap the stone.

After the stone is conveyed, the hydraulic telescopic rod 20 needs to be controlled to enable the hydraulic telescopic rod 20 to stretch, the hydraulic telescopic rod 20 stretches and retracts and swings through the two swing rods 19, the two swing plates 16 swing to drive the transmission plate 10 to transversely move upwards, the transmission plate 10 drives the connecting plate 11 to swing upwards through the transmission rod 35, the connecting plate 11 drives the driving plate 13 to swing upwards, the driving plate 13 swings upwards to drive the bottom supporting plate 14 and the two swing plates 16 mounted on the driving plate to swing upwards, and the front ends of the two swing plates 16 move far above the ground to facilitate the rotation of the excavator.
