Problems solved by technology

However, in the technology disclosed in this patent, the air inlet is far away from the excavation surface and is fixed, so it cannot suck the dust near the excavation surface, so the dust removal effect is not ideal.

Embodiment Construction

[0022] Such as figure 1 and figure 2 The airborne dust removal roadheader shown includes a fuselage 1, and the two sides of the fuselage 1 are respectively equipped with a hydraulic system 2, an operating console 3, an airborne dust removal device 4 and an electric control box 5, and the front end of the fuselage 1 is provided with a cutting Part 6. The hydraulic system 2 may include a fuel tank and a pump station. The cutting part 6 provides the power for turning and lifting. The operation table 3 is the position where workers operate the roadheader. The electric control box 5 supplies power for the operation of various parts of the roadheader. The device 4 is used to absorb and filter the dust generated by the excavation face.

[0023] The airborne dust removal device 4 is connected with an air inlet pipe 7 , the inlet of the air inlet pipe 7 extends to the cutting part 6 and is linked with the cutting part 6 . During the excavation process, the cutting part 6 will lift ...

Abstract

The invention discloses an onboard dust removing tunneller. The onboard dust removing tunneller comprises a machine body, a hydraulic system, an operating platform, an onboard dust removing device and an electric control box, wherein the hydraulic system and the operating platform are located on one side of the machine body, and the onboard dust removing device and the electric control box are located on the other side of the machine body. A cutting part is arranged at the front end of the machine body. An air inlet duct is connected to the onboard dust removing device. An inlet of the air inlet duct extends to the cutting part and is linked with the cutting part. According to the onboard dust removing tunneller, the inlet of the air inlet duct extends to the cutting part and is linked with the cutting part, hence, the inlet of the air inlet duct and the cutting part can synchronously and rotationally go up and down when the cutting part tunnels, and the inlet of the air inlet duct can be closer to the tunneling surface at any time during tunneling, so that flying dust near the tunneling surface is sucked advantageously, and the dust removing effect is improved. The onboard dust removing tunneller can be applied to dust removing during tunneller tunneling.

Description

technical field [0001] The invention relates to the field of roadheaders, in particular to an airborne dust removal roadheader. Background technique [0002] The roadheader is a large-scale machine used to excavate roadways in coal mines. The whole machine is mainly divided into: cutting part, body, walking part, etc. When the roadheader excavates in the roadway, due to the friction between the cutting part and the rock wall, a large amount of dust will be generated when the rock is broken. Work. [0003] The Chinese patent "A roadheader with integrated wet dust removal device" with publication number 202250070U provides a roadheader equipped with a dust removal device. The air inlet of the airborne dust removal device is set between the cutting part and the loading part of the roadheader. At the front end of the machine frame, the dust is sucked from the air inlet and then removed during excavation. However, in the technology disclosed in this patent, the air inlet is fa...
