Problems solved by technology

Because the frozen soil is hard, the operation is often more complicated when the frozen soil is excavated. The existing frozen soil excavation technology is mainly: firstly, the frozen soil is destroyed, and the means include cutting, hammering and crushing, etc., and then the frozen soil after the crushing is broken. Excavation, the efficiency of this process and method is very low, and the loss is very large

Abstract

A frozen earth excavator comprises a walking device, wherein a frozen earth excavating system is arranged on a lifting device of the walking device and comprises a motor, a power transmission system and an earth taking knife, the earth taking knife is in a form of a cylinder with an opening in the bottom surface, the motor adopts the power transmission system to drive the earth taking knife to perform circumferential rotating motion, a vibration source is connected with the earth taking knife through a piston rod to drive the earth taking knife to vertically vibrate at high frequency, and by means of the cooperative effect of the power transmission system and the vibration source, the earth taking knife performs vertical high-frequency vibrating motion while performing rotating cutting motion under driving of the motor and the vibration source. The frozen earth excavator c is stable and reliable to operate and efficient in excavating work, and the problems of tedious steps of frozen earth excavation, low efficiency and high equipment loss in the prior art are solved; by means of ingenious linkage of the vibrating hydraulic cylinder, the motor and the ring earth taking knife, the knife vibrates at high frequency during rotary cutting and excavating of the frozen earth, and the knife can move downwards smoothly for cutting.

Description

technical field [0001] The invention relates to the field of excavating machines, in particular to a frozen soil excavator. Background technique [0002] Permafrost refers to various rocks and soils below zero degrees Celsius and containing ice. Because the frozen soil is hard, the operation is often more complicated when the frozen soil is excavated. The existing frozen soil excavation technology is mainly: firstly, the frozen soil is destroyed, and the means include cutting, hammering and crushing, etc., and then the frozen soil after the crushing is broken. Excavation, this process and method is very inefficient and the loss is very large. Contents of the invention [0003] The present invention directly cuts out the frozen soil by rotating and cutting the soil cutting tool, but this cutting method will gradually deepen with the cutting depth, and the friction force between the tool and the soil will gradually increase, and the friction force will continue to move down...
