The right side of the fixed seat plate 31 is fixedly connected to a square tube 33. The right side of the right part of the square tube 33 is provided with a notch. By providing the notch, the rotation between the traction hook component and the traction ring component is facilitated, thereby facilitating the excavator. The body 1 drives the bucket 2 to turn. The present invention sets a square tube 33 to limit the traction hook 32 and the traction ring 42 to prevent the traction hook component and the traction ring component from being separated due to an accident.

[0030] The present invention can integrate the transportation and installation of the ditch cover. The transportation from the prefabrication factory to the construction site for installation can be completed by only using the machinery of the present invention. On the basis of realizing the integration of the transportation and installation of the ditch cover, the manual assistance of the machinery in the prior art to put the clamp on the cover and then place the cover on the transport vehicle and then disassemble the clamp is reduced, thereby saving a lot of labor and saving a large number of work links compared with the prior art.

[0031] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] Embodiment 1:

[0033] During construction, the ditch cover is installed on the bucket 2 connected to the rear of the excavator body 1 by using the cover clamping mechanism in the prefabrication processing plant. During the clamping process, the hydraulic cylinder 2 55 pushes outward, and then the curved clamping rod 54 rotates and opens at the U-shaped seat plate 52, and then the hydraulic cylinder 2 55 contracts, thereby driving the curved clamping rod 54 to clamp the ditch cover. After the ditch cover is fixed, it is transported to the construction site. After entering the site, the cover on the bucket is placed on the ditch in sequence by the cover clamping mechanism.

[0034] Embodiment 2:

[0035] First, the original bucket part of the excavator body 1 is converted into a cover clamping mechanism, and the excavator body 1 and the truck bucket 2 are connected by a traction mechanism. During the connection process, the traction mechanism moves the excavator body 1 to the front of the truck bucket 2, and makes the position of the traction hook component correspond to the position of the traction ring component. Then, the hydraulic cylinder 35 is contracted, so that the L-shaped connecting rod 351 pushes the traction block 331 to move to the outside of the square tube 33, and the fixed block 321 and the traction hook 32 move to the outside of the square tube 33 at the same time. When the traction hook 32 contacts the traction ring 42, the arc structure of the traction hook 32 presses against the traction ring 42 and rotates downward. When the hook end of the traction hook 32 is located at the ring opening of the traction ring 42, the torsion spring 34 drives the traction block 331 to rotate, and the traction hook 32 hooks the traction ring 42, and then the hydraulic cylinder 35 extends and drives the traction block 331 to move inward. At the same time, the traction hook 32 drives the traction ring 42 to shrink inside the square tube 33, thereby realizing the connection between the excavator body 1 and the bucket 2;

[0036] The ditch cover is then clamped by the cover clamping mechanism, and then the ditch cover is placed on the truck bed 2 using the rotation performance of the excavator body 1. After loading is completed, the ditch cover is tightened and bound with a hemp rope and then transported to the site for installation.

[0037] Embodiment three:

[0038] First, the excavator body 1 controls the boom hydraulic lever and the arm hydraulic lever through its own control device, and then the cover plate clamping mechanism is roughly located above the ditch cover plate;

[0039] The cover plate clamping mechanism is then controlled by the control system, and the cover plate clamping mechanism can realize 360-degree rotation under the drive of the motor 57, thereby controlling the angle of the cover plate clamping to realize flexible clamping and lifting of covers at different angles and positions;

[0040] Finally, the hydraulic system controls the hydraulic cylinder 2 55 to extend and retract. When the hydraulic cylinder 2 55 is shortened, the clamping of the cover plate can be controlled to ensure that the ditch cover plate is stable and will not fall off. The ditch cover plate is placed in the bucket 2 through the rotation of the excavator itself until the bucket 2 is full of the cover plate.

[0041] Embodiment 4:

[0042] When the inner side of the bucket 2 is filled with the ditch cover, the excavator body 1 drives the bucket 2 and pulls the ditch cover to the ditch construction site, and stops at the side of the ditch to ensure the normal flow of traffic on site. After ensuring that the ditch elevation is correct, when the excavator body 1 is parked, the bucket 2 will continue to move forward due to inertia, slide through the limit slide bar 44 and the limit slide cylinder 43, and the limit slide bar 44 is pushed up by the spring 2 45, and the inertia of the bucket 2 moving forward is offset by a large part of the limit slide bar 44;

[0043] The control system of the excavator body 1 controls the cover plate clamping mechanism to clamp and lift the cover plate, rotate it to the cover plate installation position, roughly determine the position, control the hydraulic cylinder 2 55 to extend, and then place the cover plate on the ditch and align it.
