Abstract

The invention relates to a chain excavator for excavating a deep ditch, comprising an arm lever, a driving wheel, a driven wheel, chains and buckets. The driving wheel is arranged on the upper end of the arm lever and driven by a hydraulic motor; the driven wheel is arranged on the lower end of the arm lever; the chains surround the arm lever; the buckets are fixed on the chain; the chain excavator is provided with only two buckets, and the two sections of chains arranged between the two buckets have the same length; the buckets comprise a left half bucket and a right half bucket which are connected by a pin shaft; two left mud scraping plates are arranged in the left half bucket and clung to the front side wall and the rear side wall of the left half bucket respectively; the right ends of the two left mud scraping plates are fixed on the upper opening end of the right half bucket; the two left mud scraping plates are located on the extended line of the upper opening edge of the right half bucket; two right mud scraping plates are arranged in the right half bucket and clung to the front side wall and the rear side wall of the right half bucket respectively; the left ends of the two right mud scraping plates are fixed on the upper opening end of the left half bucket; the two right mud scraping plates are located on the extended line of the upper opening edge of the left half bucket; a hydraulic oil cylinder is arranged on the right of the buckets; and a sliding chute is arranged below the buckets.

Description

1. Technical field [0001] The invention relates to an excavator, in particular to a chain excavator capable of digging deep trenches. 2. Background technology: [0002] At present, general excavators cannot dig too deep due to the limitation of the length of the boom. 3. Contents of the invention: [0003] The invention makes up for the above shortcomings of the excavator and provides a chain excavator capable of digging deep trenches. [0004] The present invention is achieved through the following technical solutions: [0005] A chain excavator, including a boom, a driving wheel driven by a hydraulic motor at the upper end of the boom, a driven wheel at the lower end of the boom, a chain around the boom, and a bucket fixed on the chain. Its special features are: chain excavation The machine only has two buckets and the length of the two chains between the two buckets is equal; the bucket is divided into a left half bucket and a right half bucket, and the left half buck...
