Hydraulic waste drilling machine

Abstract

The invention discloses a hydraulic waste drilling machine, which adopts a combined drill bit with a leading drill bit and rotating bucket drill drilling structure, realizes the functions of the preliminary hole formation of the leading drill bit and the reaming, strengthening and drilling of the rotating bucket drill, and ensures the stability of hole drilling and hole forming rate during gradual drilling. The assembly and disassembly structure of a sliding multi-drill pipe improves the handling efficiency of the drill pipe, and is combined with the leading drill bit and rotating bucket drill drilling structure to shorten the hole forming time and improve the hole forming efficiency of the drilling machine. A hydraulic system is used for loading drilling force so as to greatly reduce thehole forming time. The drilling machine can quickly form holes and does not need strengthening, solves the difficulties of difficult hole formation, poor stability and low drilling efficiency of landfill, and indirectly improves the construction efficiency of a drilling and gas collecting system of landfill sites, and reduces the operating cost.

Description

technical field [0001] The invention discloses a hydraulic garbage drilling machine, which belongs to the category of engineering machinery. Background technique [0002] With the gradual implementation of national policies on environmental protection, low-carbon emission reduction and resource utilization, the resource utilization of landfill gas generated during the large-scale construction of domestic waste landfills has become an urgent problem in the field of national energy and environment. major environmental issues. The efficient collection of landfill gas is of great practical significance to promote the resource utilization of landfill gas and improve the operation and management of landfill sites. [0003] At present, landfill gas collection mainly adopts two methods: vertical collection and horizontal collection. Most domestic waste landfills adopt the vertical collection method, mainly for closed landfills or capped landfill units, using the landfill gas gabio...

Problems solved by technology

[0005] At present, relevant equipment has been developed for landfills in China. However, due to the small hole diameter and low stability, repeated drilling is common, resulting in very low hole formation efficiency. Moreover, a considerable part of the drilling rigs rely on manual drilling. If the degree is too high, it is also an important factor that drastically reduces the pore-forming efficiency.

In foreign countries, landfill gas resource utilization facilities and machinery have been developed earlier, but at present, the mechanical cost of drilling holes for landfill bodies is high, the quality assurance rate of holes is low, and the drilling rate is not high, which is difficult to meet the promotion of landfill in my country.
