Problems solved by technology

[0003] 1. The service life of the blade when digging grooves is much lower than the service life of parts such as chains, but in this chain, the blade and the chain are fixed together by welding. When the blade needs to be replaced, the chain can only be replaced as a whole , there is the disadvantage of high replacement cost, and when corresponding to different widths of ravines, it is necessary to replace chains of different widths, which not only increases product costs but also brings great inconvenience to construction
[0004] 2. Existing trenching machines cannot carry out special excavation grooves according to different lands, that is, the same blade is used for soft soil and hard body, resulting in too slow slotting in soft soil, and too fast wear of the blade in hard soil technical issues

Abstract

The invention relates to a trenching assembly of a chain type trencher. Trenching tooth sets are arranged on a cutter chain of the trenching assembly, the trenching tooth sets of different specifications can be conveniently replaced through a first mounting structure, then grooves of different specifications can be rapidly matched, after the trenching tooth sets are abraded, the trenching tooth sets only need to be detached and replaced with new trenching tooth sets, then the trenching tooth sets can be directly used, a chain mounting block does not need to be replaced, the construction cost is reduced, when trenching is carried out on soil with different hardness, different chain units are arranged, stress is more uniform, abrasion is smaller, efficiency is higher, and then the trenching assembly adapts to different land conditions. With adoption of a soil cleaning scraping plate device, accumulation of covering soil after trenching can be reduced, and the quality of a trench is improved; with adoption of a spiral soil discharging device, cut soil returning into the trench can be reduced, and the working efficiency and the quality of the trench are improved; meanwhile, dug soil is accumulated beside the trench through the spiral soil discharging device, and backfilling after construction is facilitated.

Description

technical field [0001] The invention relates to the field of ditching machines, in particular to a ditching assembly of a chain type ditching machine. Background technique [0002] In the prior art, before conventional laying of pipelines, manual or mechanical methods are mostly used to dig and groove. Among them, the trencher is one of the main types of construction machinery, and it is a trenching machine used in earthwork construction. It is widely used. It is used in the construction of farmland water conservancy, the laying of communication cables and oil pipelines, municipal construction and military engineering, etc. The functions of the trencher and the excavator have many similarities. Both of them have the functions of entering soil (soil or rock), crushing soil and taking soil. The advantages of the trencher are continuous operation, high construction efficiency, and small surface damage. It is especially suitable for laying pipelines. Even in hard geological con...
