Amphibious excavator

Abstract

The invention discloses an amphibious excavator, and the amphibious excavator comprises a buoyancy tank crawler excavator body, a front buoyancy tank and a rear buoyancy tank are respectively formed at the front side and the rear side of a rack of the machine body of the buoyancy tank crawler excavator body, the top of the rear side of the front buoyancy tank is hinged to a piston rod of a first hydraulic cylinder hinged to the rack, two ends of the rear side of the front buoyancy tank below the first hydraulic cylinder are hinged to the rack respectively, the top of the rear side of the rear buoyancy tank is hinged to a piston rod of a second hydraulic cylinder hinged to the rack, two ends of the rear side of the rear buoyancy tank below the second hydraulic cylinder are jointed to the rack respectively, the front sidewall of the front buoyancy tank leans backward from the upper side to the lower side, the top surface of the front buoyancy tank leans upwards from the front side to the rear side, the hydraulic cylinder operation button is formed in the cab of the machine body of the buoyancy tank crawler excavator, the first hydraulic cylinder and the second hydraulic cylinder are connected to the control device through the hydraulic cylinder operation button. The running resistance is small in the water, the running speed is high, and the anteverted phenomenon of the body at the time of mechanical arm of excavator for protracting can be avoided.

Description

Technical field: [0001] The invention relates to an amphibious excavator. Background technique: [0002] With the rapid development of the national economy, environmental protection and water resources issues are becoming more and more important. In recent years, engineering ships and dredging equipment have made great progress and development, but they still cannot meet the needs of economic development and environmental improvement. In particular, the dredging and dredging of inland rivers still adopts the traditional manual operation method at present. For the frequent mudslides in recent years and the resulting barrier lakes, except for a few areas where mechanical equipment can be used, most areas are Use troops to carry out manual dredging. For this reason, a pontoon crawler excavator has appeared. Side pontoons are arranged on both sides of the pontoon, and a crawler walking mechanism is arranged on the side pontoon. Strong, widely used in inland rivers, lakes, dan...

AI Technical Summary

Problems solved by technology

However, when the existing pontoon crawler excavator floats in water, the resistance is relatively large, and the driving speed is relatively slow, and when the mechanical arm is stretched forward in the water, the whole machine will lean forward.
