Referring to fig. 4-7, in order to achieve that the anti-return rod 5 can be automatically clamped on the anti-drop gear row 9, a local avoiding groove is formed in the side wall of the rear positioning wheel 7, a reset push block 10 is movably installed in the local avoiding groove on the side wall of the rear positioning wheel 7, a reset spring 12 located in the rear positioning wheel 7 is fixedly installed on the side wall of the reset push block 10, an adjusting push rod 11 facing the reset push block 10 is fixedly installed on the side wall of the anti-return rod 5, therefore, in the actual use process, the reset push block 10 is pushed by the elastic force of the reset spring 12, the adjusting push rod 11 is driven to pull the anti-return rod 5 to deflect towards the anti-drop gear row 9, the anti-return rod 5 is always clamped on the side wall of the anti-drop gear row 9, the anti-drop gear row 9 is always in a unidirectional rotation state in a normal state, the middle line axis of the adjusting push rod 11 and the middle line axis of the anti-drop rod 5 can be selected between forty five degrees and ninety five degrees in the actual arrangement process, and the anti-return rod 5 is pushed to be pushed upwards, and the reset spring 10 is compressed when the anti-return rod 5 is pushed upwards.
Referring to fig. 4-7, in order to facilitate the rear positioning wheel 7 to unlock the bucket, and simultaneously ensure that the rear positioning wheel 7 is in a state capable of clamping the hanging lugs of the bucket, the rear positioning wheel 7 is forced to rotate by forced pulling of the anti-return rod 5 in the actual use process, so that the rear positioning wheel 7 is ensured to be separated from the hanging lugs of the bucket by adjusting the push rod 11 when the push rod 11 presses the rear positioning wheel 7, wherein the thickness of one end of the reset push block 10 is twice as thick as that of the other end of the reset push block 10, the side wall of the reset push block 10 is ensured to be an arc surface.
The working principle of the invention is as follows: when the excavator is used, the distance adjusting screw 2 is used for adjusting and rotating, the distance value between the front positioning hook 4 and the rear positioning wheel 7 is limited, so that the rapid fixing of the excavator buckets with different distances is realized, and the excavator buckets are not shown in the figure.
Then, the front positioning hook 4 is used for fixing one hanging lug of the excavator bucket at first, then the main hook body 1 is pressed, the rear positioning wheel 7 is directly pressed on the other hanging lug, the rear positioning wheel 7 is enabled to rotate when passing through the hanging lug along with the continuous pressing of the main hook body 1, until two hanging lugs on the excavator bucket are respectively arranged between the rear positioning hook angle 8 and the front positioning hook 4, at the moment, the hanging lug at the rear positioning hook angle 8 is synchronously clamped and fixed by the rear positioning wheel 7 and the rear positioning hook angle 8, meanwhile, the main hook body 1 is pressed downwards, and simultaneously, the reset push block 10 is enabled to push the adjusting push rod 11 to deflect downwards under the action of the elastic force of the reset spring 12, so that the anti-back rod 5 is pressed on the anti-back tooth row 9, and after the rear positioning wheel 7 is fixed, the anti-back rod 5 is directly clamped on the anti-back tooth row 9.
When the main hook body 1 lifts the bucket, the bucket is pulled to enable the rear positioning wheel 7 to rotate clockwise, the rotation direction is shown in fig. 6, at this time, the anti-falling gear row 9 has a trend of pushing the anti-falling bar 5 to the right side because the anti-falling gear row 9 is limited by the anti-falling bar 5, and the anti-falling bar 5 is pushed to the right side, and in combination with fig. 3, the anti-falling bar 5 is forced to slide closely to the inclined plane of the fastening guide groove 101, so that the anti-falling bar 5 is further forced to press downwards, and the anti-falling bar 5 is prevented from being separated from the anti-falling gear row 9.
When the bucket is required to be disconnected, the anti-reverse rod 5 is pulled upwards through the hydraulic oil cylinder 3, so that the anti-reverse rod 5 is forced to lift upwards, the anti-reverse rod 5 is separated from the anti-falling gear row 9, meanwhile, the anti-reverse rod 5 is lifted upwards to force the adjusting push rod 11 to extrude the reset push block 10 and compress the reset spring 12, when the adjusting push rod 11 extrudes the compressed reset spring 12 again through the reset push block 10, the rear positioning wheel 7 is forced to rotate clockwise, the direction is referred to in fig. 6, and then the bucket is separated from the rear positioning wheel 7 through the rotation of the rear positioning wheel 7 and the gravity of the bucket.
When the hydraulic cylinder 3 fails, at this time, the anti-reverse rod 5 is still blocked on the rear positioning wheel 7, normal use is not affected, and when connection is required to be released, because the failure of the hydraulic cylinder 3 is required to be sleeved on the anti-reverse rod 5 through tools such as steel pipes by an external person, the anti-reverse rod is lifted upwards, at this time, one end of the anti-reverse rod 5 takes a ball joint part as a fulcrum, the length of a power arm of the anti-reverse rod 5 is greater than the resistance arm of the adjusting push rod 11, the external person can lift the anti-reverse rod 5 in a labor-saving mode, and therefore the anti-reverse rod is used for releasing a bucket.
