Multifunctional excavator
The invention relates to a multifunctional excavator. A drag-type agricultural tool mechanism is additionally arranged on an existing excavator. According to the structure of the excavator, a transition frame, crossbeams matched with a suspension bracket, connecting rods and the like are designed reasonably to be combined into a three-point suspension device, and the drag-type agricultural tool and the excavator are combined together reliably. Through matching of a lifting oil cylinder and lift arms, the drag-type agricultural tool can be retracted or released in the vertical direction so as to be controlled to enter a farming state or a general mechanical operating state. Meanwhile, on the basis of a valve way in the excavator, a control valve set is additionally arranged and matched with an operation handle, oil supply operation of the lifting oil cylinder is achieved through an oil way of the excavator, and normal mechanical operation of the excavator is not affected. Multipurpose application extension of the excavator is achieved, the majority of farmers are helped to use the excavator to carry out farming operation in a busy farming season, and the excavator is not left unused; the utilization rate of the excavator is increased, optimal configuration of resources is achieved reasonably, and a new income creating way is achieved for the users.
