The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
Such as these improvements: the groove weld is optimized to be a composite weld of the groove weld and the fillet weld, a simple groove weld is improved to be a groove weld with a backing plate, and an external process hole is improved to be an assembled structure.
Such as these wettings: on the basis of the structure of the invention, a reinforcing structure, a mechanical limiting structure, a hoisting structure and the like are added.
In conclusion, the invention provides a bucket rod of a multi-box back-hoe excavator, which solves the problem that the traditional bucket rod is easy to open and fail under the action of larger load and impact force. The whole bucket rod is divided into three large box bodies through the side plates, the inside of each large box body is divided into a plurality of small box bodies through the reinforcing plates, and the small box bodies are distributed in an orderly and crossed mode to form a multi-box-body structure of the bucket rod of the backhoe excavator. The distribution of the inner reinforcing plates of the middle box body is complicated because the middle rear supporting component connected with the outer oil cylinder and the middle lower supporting component connected with the movable arm in the middle box body are positioned at the rear part of the middle box body and are stressed greatly, and the force borne by the middle rear supporting component and the middle lower supporting component is dispersed into the left box body and the right box body through the plurality of reinforcing plates distributed in a crossed mode. The middle reinforcing plate III 308, the middle reinforcing plate IV 309, the reinforcing plate I310B and the reinforcing plate II 310C play roles in centering stress transmission of the rear bearing assembly and supporting the round pipe 310A and the middle rear closing plate assembly 304. The middle reinforcing plate I306 and the middle reinforcing plate II 307 are radially distributed around the middle and lower bearing assembly, so that the stress of the middle and lower bearing assembly can be transmitted to each box body. By the method, the load and impact force on the bucket rod can be quickly and effectively dispersed and transmitted to each small box body, the maximum stress on the bucket rod is reduced, and the damage of stress concentration is reduced, so that the structural strength of the bucket rod is improved, and the service life of the bucket rod is prolonged.
The invention also provides an excavator which comprises the bucket rod of the multi-box back-shovel excavator.
